[0001] The present invention relates to a frame assembly kit for construction work, to a
fixation device mountable on the frame assembly kit, to a method for manufacturing
and for mounting a frame assembly kit.
[0002] For construction work there are known frames for supporting wall openings or frames
for mounting windows or doors. Conventional frames are pre-assembled in factory by
a skilled worker and afterwards are transported to the site where they are installed
and fixed for supporting wall openings. The installation on site may need further
tools, such as a hammer and nails or a screw driver and screws for fixing the pre-assembled
frame to a wall opening.
[0003] Often the pre-assembled frames have a size that two person may carry it in order
to prevent damages to the surrounding and to the frame itself. Therefore each frame
may be carried separately.
[0004] Moreover, a pre-assembled frame may need space during transportation in a transportation
vehicle. A conventional frame for a door with standard dimensions of 2100 x 820 x
100 millimeters may require a volume for transporting or storing of about 0,1722 cubic
meters.
[0005] KR 101024267 B1 describes a prefabricated timber window frame and door frame using an edge connection
member. A vertical member and a horizontal member are cut in a desired length. The
edge connector is fixed to the four corners of the vertical member and horizontal
member. The edge connector is integrally fixed to the vertical member and horizontal
member by using a plurality of screw nails.
[0006] There may be a need to provide a frame assembly which may be built up on site without
using additional tools for building up.
[0007] This problem is solved by a frame assembly kit for construction work according to
claim 1. Moreover, the problem is solved by a fixation device for a frame assembly
kit according to claim 13. Furthermore, there is provided a method for manufacturing
a frame assembly kit according to claim 14 and a method for mounting a frame assembly
kit according to claim 15 in order to provide a solution for the given problem.
[0008] According to an exemplary embodiment of the present invention there may be provided
a frame assembly kit for construction work comprising a permanent frame section and
a temporary frame section for stabilizing the permanent frame section in an operating
mode of the frame assembly kit. The permanent frame section may comprise a first supporting
member, a second supporting member and an attachment member. Moreover, the attachment
member may be connected with the first supporting member via a first plug connection
in the operating mode and the attachment member may be connected with the second supporting
member via a second plug connection in the operating mode. The temporary frame section
may comprise at last one stabilization member, wherein the first supporting member,
the second supporting member and the attachment member are building a frame and the
stabilization member may be surrounded by the frame. Furthermore, the temporary frame
section may be connected with the permanent frame section via a plurality of third
plug connections in the operating mode.
[0009] In other words, the invention relates to a frame assembly kit for construction work
comprising a permanent frame section and a temporary frame section. The temporary
frame section is utilized for stabilizing the permanent frame section in an operating
mode of the frame assembly kit. The frame assembly kit comprises at least three outer
members forming a frame and at least one inner member stabilizing the frame. All members
are connected to each other via plug connections.
[0010] The frame assembly kit according to exemplary embodiments of the present invention
may be transported and stored in a disassembled mode and may be mounted on site or
at a place of installation being in operating mode. For installation there may be
no need of any tools, which may reduce the risk of injuries for a craftsperson. The
installation time for the frame including the permanent section and the temporary
frame section may be less than five minutes, in average two minutes. The assembling
may be performed on site, which may reduce costs of skilled labor for mounting.
[0011] The frame assembly kit is easy to transport, since only one person may be needed
for transporting and mounting. In the disassembled transporting mode the individual
parts of the frame assembly kit can be stacked on each other and also the frame assembly
kit may be stackable on a further frame assembly kit. In relation to the stackable
characteristic the frame assembly kit may comprise profiles.
[0012] The frame assembly kit may be utilized to support door frames or window frames. The
frame assembly kit may allow mounting of firm structures and may be attached permanently
to vertical faces by fixation elements. Furthermore it is also possible to use the
frame assembly kit for different kind of construction work, for example for supporting
tunnel constructions in mining or for similar fields of application.
[0013] By providing a frame comprising a permanent section and a temporary section it is
possible to adapt each section to its individual requirements. For example, the permanent
section can be made of particularly robust material for properly supporting masonry
and the temporary section can be made of material, which is easily to work with, to
adapt to changing requirements. Because of the variable sections, the individual parts
can be chosen.
[0014] According to an exemplary embodiment of the present invention, at least one third
plug connection connecting the permanent frame section and the temporary frame section
may comprise a male geometry and a female geometry, wherein the male geometry may
be located at the temporary frame section and the female geometry may be located at
the permanent frame section.
[0015] A similar to plug and socket geometry may be utilized for connecting parts of the
temporary frame section with parts of the permanent frame section. For example the
male geometry may be a pin, whereas a female geometry may be a recess. Plug and socket
geometries have the advantage that the plugging may be connected and disconnected
in a fast manner without any need of a tool. Thus, a simple, fast and accurate connection
method is provided.
[0016] Female parts of the connection may be located at the permanent frame section while
male parts of the connection may be located at the temporary frame section. This configuration
may have the advantage, that in a disassembled mode, the frame assembly kit is reduced
in size, since no male connection appears at an outer surface of the supporting member
when stacked. The male connection may be located at one or at both ends of a stabilization
element and thus extending in length of the member and not on a side surface of a
member.
[0017] It is of advantage to provide the female part at the permanent frame. In case the
temporary frame section is removed and the permanent frame section stays installed,
no further part of the permanent frame may need space into the inner of the permanent
frame and therefore avoiding hurting passing persons and goods through the frame.
In case of using the permanent frame as a pre-frame for further installation, the
female parts may be covered by other parts to be mounted on the permanent frame, such
as a window frame or a door frame without any need to remove parts of the permanent
frame.
[0018] Moreover, it is possible to split the permanent section and the temporary section
after the surrounding of the permanent frame section is in its final status, for example
after a wall is dried. The permanent frame section could stay installed and could
serve for further installation, while the temporary frame section could be removed
in order to provide an opening in the wall. In such a case the permanent frame may
be utilized as a pre-frame for mounting a window, a door or a decoration on it. In
addition during construction work of a surrounding wall the temporary frame section
could be temporarily removed for passing through the permanent frame section, for
example when a craftsman may need to go through inner of the permanent frame section
for leaving the site.
[0019] According to an embodiment of the invention, at least one third plug connection connecting
the permanent frame section and the temporary frame section may be a dovetail connection.
[0020] A dovetail connection is a special geometry of a male and female geometry. A dovetail
connection is easy to manufacture. Female parts of the dovetail connection may be
located at the permanent frame section while male parts of the dovetail connection
may be located at the temporary frame section.
[0021] According to an exemplary embodiment of the present invention, the frame assembly
kit may comprise a first volume in the operating mode and may comprise a second volume
in a non-operating mode, wherein the second volume in the non-operating mode is about
nine times smaller compared to the first volume in the operating mode.
[0022] The frame assembly kit may be packable in a compact manner in the non-operating mode
for transport and storage of the frame assembly kit. In the non-operating mode the
assembly kit may have an ashlar-formed geometry. A small volume of the frame assembly
kit in the non-operating mode is advantageous for storing or transporting the frame
assembly kit. The reduced volume in the non-operating mode has the advantage that
damages to the frame assembly kit, damages to parts of a surrounding or a transport
vehicle may be reduced as well as possible injuries to a person handling the frame
assembly kit.
[0023] It may not be necessary to mount the frame assembly kit in factory as a pre-assembly.
Therefore, the capacity for frame transportation may be increased compared to pre-assembled
frames. A conventional door frame or the frame assembly kit in the operating mode
may have for example dimensions of 2100 x 820 x 100 millimeters, which may result
in a volume of about 0,1722 cubic meters in the operating mode. The same frame assembly
kit may have a volume of about 0,0189 cubic meters in the non-operating mode or disassembled
mode for storing or transporting.
[0024] According to an exemplary embodiment of the present invention, the attachment member
may comprise a shape which is one of the group of shapes consisting of an arc, a half
cycle, a section of a cycle, a half ellipse, a section of a half ellipse, a horizontal
line, a pointed shape, a pointed shape combined with an arched form, a pointed shape
combined with a straight line, a straight line, and combinations thereof.
[0025] The attachment member may be exchangeable. The frame assembly kit may be utilized
for different shapes of openings. The geometrical form of the permanent frame section
may be easily adapted by changing the attachment member while using unchanged supporting
members.
[0026] There may be provided different kinds of geometrical forms for the attachment member,
such as an arched form, which may be used for window frames, a straight form, like
a conventional rectangular window frame or door frame, a semicircular form, a form
having a quadrant rounding at the corners of the attachment member, a pointed form
with straight sides or a pointed form with circular sides. Depending on the style
of the building or the requirements to the form of the window or door to be mounted
afterwards, it may be understood to use additional geometrical forms for the attachment
member.
[0027] According to an embodiment of the invention, the frame assembly kit may made of wood
or of material partly comprising wood.
[0028] Wood is a material, which is easy to handle, not only during manufacturing of the
frame assembly kit, but also on site. During transportation wood is light in weight
compared to metal. Different kinds of wood may be suitable for the manufacture of
the frame assembly kit.
[0029] It is possible that a different kind of woods may be utilized for the permanent frame
section and for the temporary frame section, respectively. It may also be possible,
that other material than wood may be utilized, such as metal or plastic, for example
for at least some parts of the frame assembly kit, for example for the stabilization
elements. A material partly consisting of wood would also be suitable for manufacturing
the different members of the frame assembly kit. Thus, material derived from wood
may be utilized.
[0030] According to an exemplary embodiment of the present invention a member of the permanent
frame section may comprise a first height, wherein the stabilization member of the
temporary frame section may comprise a second height. It may be foreseen that the
second height is smaller than the first height.
[0031] The members of the permanent frame section may have a squared cross section while
the members of the temporary frame section may have a rectangular cross section. This
is of advantage to reduce weight without limiting the stability of the assembled frame
assembly kit. Moreover, a different height in relation to the cross section of the
members is advantageous when building the plug connection between the permanent frame
section and the temporary frame section. The plug and socket connection may comprise
a body stop integrated inside a recess in order to stop the insertion movement during
mounting and avoiding slipping of the male part through the recess of the plug and
socket connection. Thus the male part has a predefined position within the female
part of the plug and socket connection.
[0032] According to an exemplary embodiment of the present invention the frame assembly
kit may comprise a fixation device for fixing the frame assembly kit to a surrounding
in the operating mode, wherein the fixation device comprises a two-dimensional geometry
in a first position and a three dimensional geometry in a second position.
[0033] The first position may be a position for preparing the mounting of the frame assembly
kit. The first position of the fixation device may be present during transportation,
during plugging the permanent frame section and connecting the temporary frame section
with the permanent frame section. After building up a frame comprising at least the
permanent frame section the fixation device may be utilized in a second position in
order to fix the permanent frame section onto a wall or surrounding.
[0034] The fixation device may have a flat geometry in the first position, which is understood
as a two dimensional geometry. A geometry which is not flat, for example a U-shape
or a V-shape is understood as a three dimensional geometry. In case the fixation device
comprises a fastening element, such as a screw or a nail, which may be located nearby
the surface of the fixation element with one of its end, then the geometry is also
understood as two-dimensional as long as further parts of the fixation device do not
provide any peaks in relation to the surface of the fixation device.
[0035] According to an exemplary embodiment of the present invention the fixation device
may comprise a fixation element and a fastening element, wherein fixation element
may comprise a longitudinal axis and a center part. Moreover, the fixation element
may be rotatable mounted at the center part by the fastening element. In the first
position the longitudinal axis of the fixation element may be in parallel to a longitudinal
extension of the member of the permanent frame section at the location where the fixation
element is installed. In the second position the longitudinal axis of the fixation
element may be approximately orthogonal to the longitudinal extension of the member
of the permanent frame section at the location where the fixation element is installed.
[0036] According to an exemplary embodiment of the present invention the three-dimensional
geometry of the fixation device in the first position may be provided by the fixation
element, wherein an angle of about 5 to about 90 degrees, preferably 45 degrees, may
be present between the longitudinal axis of the fixation element and a surface of
the permanent frame section.
[0037] According to an exemplary embodiment of the present invention the fixation device
may be completely embedded in a longitudinal groove of the permanent frame section
in the first position, and the fixation device may be partly embedded in the longitudinal
groove of the permanent frame section in the second position.
[0038] It may be foreseen that the groove in which the fixation device is installed may
be a longitudinal groove, which may extend over the whole length of a member of the
permanent frame section or only over a part of the length of the frame surface of
a member. Advantageously at least the supporting members comprise a groove extending
over the whole length of the outer frame surface. Therefore, it would be possible
to select flexibly at which positions the fixation device may be mounted inside the
groove.
[0039] A two dimensional geometry of the fixation device may save space during a transportation
of the frame profile assembly kit. A two dimensional geometry may be understood as
a geometry which is a flat geometry. The fixation device may be for example a metal
plate which is bendable from a two dimensional geometry into a three dimensional geometry,
for example a V-shape geometry.
[0040] Moreover, the fixation element may be a clamping plate, which may be adapted to serve
in the operating mode by providing a clamping pressure at the edges of a longitudinal
groove at the frame surface. In operating mode the part of the fixation element, with
which the fastening element is engaged, may be embedded in the groove and the other
part of the fixation element, which is rotated over the edge of the frame surface
to the groove, is sticking out of the groove and is clamped because of the mechanical
tension of the fixation element to the edge of the frame surface to the groove. Without
the use of force to the fixation element in a direction of rotation, the fixation
element may be clamped in operating mode so that the fixation element may not switch
to non-operating mode by itself.
[0041] The different levels of the outer frame surface and of a ground surface of the groove
allow, that the fixation element may be bended in that direction, which would be necessary
for the fixation element to stick out of the groove. As a consequence the fixation
element may touch the edge of the frame surface on its way out of the groove. Moreover,
the fixation element may be a clamping plate, made of bendable metal comprising at
least one circular recess for attaching the fastening element. Other materials may
also be suitable, such as synthetic material, rubber material or constructions made
of bendable wood.
[0042] According to an exemplary embodiment of the present invention the fixation device
may comprise a fixation element with a first end and a second end, wherein at least
the first end or the second end of the fixation element comprises a fork like manner
geometry.
[0043] A fork like manner geometry may be of advantage for fixation, since a fork like manner
geometry comprises at least two end parts, which may be available for fixing the permanent
frame section onto a surrounding.
[0044] Using a fixation element with a fork like manner geometry is of advantage, since
the frame assembly kit may be mounted without any use of a tool, such as a hammer
and without any need of mounting nails to the frame surface of the supporting members
or the attachment element. The fixation element may be completely embedded in the
groove during a non-operating mode of the frame assembly kit. Thus the risk of injuries
may be reduced, because it may not be possible to come unintentionally in contact
with sharp edges of the fixation element.
[0045] According to an exemplary embodiment of the present invention the fixation device
may comprise a fixation element and a fastening element, wherein fixation element
may comprise a longitudinal axis and a center part. Moreover, the fixation element
may be rotatable mounted at the center part by the fastening element. The fixation
element may comprise a two-dimensional geometry in a first position and a three dimensional
geometry in a second position, wherein the first position is a position of preparing
a fixation and the second position is a position of fixing the fixation element to
a surrounding.
[0046] According to an exemplary embodiment of the present invention there is provided a
method for manufacturing a frame assembly kit. The method comprises manufacturing
a first supporting member comprising a first part of a first plug connection, manufacturing
a second supporting member comprising a first part of a second plug connection, manufacturing
an attachment member, comprising a second part of the first plug connection and comprising
a second part of the second plug connection, manufacturing a stabilization member,
comprising a first part of a third plug connection and comprising a first part of
a fourth plug connection, manufacturing a second part of the third plug connection
at the first supporting member, and manufacturing a second part of the fourth plug
connection at the second supporting member or at the attachment member.
[0047] The manufacturing of the frame assembly kit may be uncomplicated since several parts
of the frame assembly kit may comprise an identical connecting geometry and identical
dimensions in length, width and height. In case the supporting members are manufactured
in three parts then gluing together or clamping together may be performed in addition.
[0048] According to an exemplary embodiment of the present invention there is provided a
method for mounting a frame assembly kit. The method may comprise providing a first
supporting member, providing a second supporting member, providing an attachment member,
providing a stabilization member, building up a permanent frame section by connecting
the first supporting member with the attachment member via a first plug connection,
connecting the first supporting member with the attachment member via a plug connection,
building up a temporary frame section by connecting the stabilization member with
the first supporting member via a third plug connection, connecting the stabilization
member with the second supporting member or with the attachment member via a fourth
plug connection and fixing the permanent frame section to a surrounding.
[0049] The method may be performed at the place of installation of the frame assembly kit
into a frame. The plurality of members may be transported in a stacked way and may
be mounted by plug connections without any need of further tools. A fixation device
may be installed at members of the permanent frame section in advance before stacking
the frame assembly kit into a small unit and before transporting.
[0050] Due to a quick mounting of the frame profile assembly kit, for example in less than
five minutes, only one person may be needed to mount the assembly kit. Using the frame
profile assembly kit a person may save time and consequently reducing the costs during
manufacturing a wall opening.

[0052] Fig. 1 illustrates an exemplary embodiment of a frame assembly kit 100 in a disassembled
mode before mounting the frame assembly kit 100. The frame assembly kit 100 of Fig.
1 comprises a permanent frame section 10 and a temporary frame section 20 for stabilizing
the permanent frame section 10 in an operating mode, shown in Fig. 2. The permanent
frame section 10 comprises a first supporting member 11, a second supporting member
12 and an attachment member 13 of a straight form. The attachment member 13 may be
mounted on top of the frame assembly kit and may be connected with the first supporting
member 11 via a first plug connection 31 and with the second supporting member 12
via a second plug connection 32, wherein the supporting members may be mounted in
a vertical direction.
[0053] In Fig. 1 the first supporting member 11, the second supporting member 12 and the
attachment member 13 are arranged to build a U-shape as a permanent frame section
with orthogonal angles at the plug connections 31, 32. The first plug connection 31
and the second plug connection 32 comprise a male part 34 and a female part 35. The
attachment member 13 comprises a first end and a second end for plugging, wherein
the attachment member 13 comprises at each end a male part for connecting with the
first supporting 11 member and the second supporting member 12, respectively. The
first supporting member 11 and the second supporting member comprise a female part
for connecting with the attachment member 13, respectively.
[0054] In Fig. 1 the temporary frame section 20 comprises a first stabilization member 21
and a second stabilization member 22. The first stabilization member 21 and the second
stabilization member 22 may be connected via a third plug connection 33 with the permanent
frame section 10, respectively as shown in Fig. 2. The third plug connection 33 is
a dovetail connection 36, wherein a female part 35 of the dovetail connection 36 is
present at the supporting members 11, 12 and a male part 34 of the dovetail connection
36 is present at the stabilization members 21, 22 of the permanent frame. Thus, the
four dovetail connections 36 may connect the temporary frame section 20 with the permanent
frame section 10, as shown in Fig. 2.
[0055] Fig. 2 illustrates the frame assembly kit 100 of Fig. 1 in an assembled mode forming
an assembled frame 10, 20 comprising the permanent frame section 10 and the temporary
frame section 20 connected to each other. The first supporting member 11, the second
supporting member 12 and the attachment member 13 are forming the permanent frame
section 10. The first stabilization member 21 and the second stabilization member
22 are located in the inner of the permanent frame section 10 and are surrounded by
the first supporting member 11, the second supporting member 12 and the attachment
member 13, respectively.
[0056] In Fig. 2 the first supporting member 11 and the attachment member 13 are forming
an orthogonal angle at a first corner of the assembled frame 10, 20, wherein the second
supporting member 12 and the attachment member 13 are forming a second orthogonal
angle at a second corner of the assembled frame 10, 20. The first supporting member
11, the second supporting member 12 and the attachment member 13 are building a frame
which surrounds the first stabilization member 21 and the second stabilization member
22.
[0057] Fig. 3 illustrates the frame assembly kit 100 of Fig. 1 and Fig. 2 in a disassembled
non-operating mode. In the non-operating mode the frame assembly kit 100 may be stored
or transported. In the non-operating mode the frame assembly kit 100 is compact and
comprises a small volume in comparison to the frame assembly kit 100 in the operating
mode or compared to a conventional frame profile. The volume of the frame assembly
kit 100 results from multiplying length 51, width 52 and height 53, which are indicated
in Fig. 3 and Fig 1 for a disassembled mode or non-operating mode and for an assembled
mode or operating mode.
[0058] In Fig. 3 the two supporting members 11, 12 are stacked one up each other as a first
and a second layer. The attachment member 13 is stacked above the first supporting
members 11, 12 at one side of the upper surface of the stacked outer supporting members
11, 12. The two stabilization members 21, 22 are stacked next to each other upon another
side of the upper surface of the stacked outer supporting members 11, 12. The female
part of the dovetail connection 30 and the male part of the dovetail connection 30
are mounted to the outer supporting members 11, 12, the stabilization members 21,
22 and the attachment member 13.
[0059] Fig. 4 illustrates an exemplary embodiment of a dovetail connection 36. The dovetail
connection 36 may be used for connecting the supporting member 11 with the stabilization
member 21. The stabilization member 21 comprises a male part 34 which fits into a
female part 35 present at the supporting member 11. The stabilization member 21 has
a thickness, which may be half of the thickness of the supporting member 11. The different
thicknesses create a body stop at the female part 35. The body stop has the effect
that the stabilization member 21 is fixed without any need of further preparations,
since the body stop may stop the stabilization member 21 during plugging in the direction
of insertion, wherein the insertion may be performed from a surface of the supporting
member 11 in orthogonal direction of longitudinal elongation of the supporting member
11.
[0060] In Fig. 4 the supporting member 11 of the permanent frame section 10 comprises a
first height 58 and the stabilization member 21 of the temporary frame section 20
comprises a second height 59, wherein the second height 59 is smaller than the first
height 58. For example the second height 34 is half of the first height 58. A different
height may provide a body stop in the inner part of the recess 35. The body stop is
formed by a surface inside the female part 35 and may support a fixing of the stabilization
member 21 onto the first supporting member 11.
[0061] It may be foreseen that all dovetail connections 36 utilized for the frame kit assembly
100 are provided with a body stop and are providing a same insertion direction in
relation to the assembled frame assembly kit 100. This would have the advantage, that
all members 21, 22, 23, 24, 25, 26, 27 of the temporary frame section 20 which may
be connected all via a dovetail connection 36 may be plugged and unplugged from one
front side of the frame assembly kit 100 during mounting and in the operating mode.
[0062] Fig. 5 illustrates a further exemplary embodiment of a frame assembly kit 100 in
an operating mode. The frame assembly kit 100 comprises permanent frame section 10
comprising a first supporting member 11, a second supporting member 12, a first attachment
member 13 and a second attachment member 14. The permanent frame 10 has a closed form
and may be utilized for example for preparing a window mounting.
[0063] It may be foreseen that the frame assembly kit 100 may be installed in a vertical
direction, wherein the first supporting member 11 and the second supporting member
12 are installed vertical in relation to ground. It would also be possible to install
the frame assembly kit 100 of Fig. 5 in a horizontal direction due to its closed form,
wherein one of the supporting members 11, 12 is mounted at the top of the permanent
frame 10 and the both attachment members 13, 14 are mounted in vertical direction
in relation to ground.
[0064] In the illustrated Figures a supporting member 11, 12 has a length which is longer
than a length of an attachment member 13, 14. However, it may also be possible, that
the length of the attachment member 13, 14 is longer compared to the length of the
supporting member 11, 12, respectively. Since the lengths of all members of the frame
assembly kit 100 are adaptable in relation to the requirements of installation, the
length of the supporting member 11, 12 could also be equal to the lengths of the attachment
member 13, 14. The members of the frame assembly kit 100 may also vary in cross section
whereas for example the members of the permanent frame section 10 may have a squared
size and the members of the temporary frame section 20 may have a rectangular size.
In this configuration one side of the rectangular may be half of the side of the squared
cross section.
[0065] In Fig. 5 the frame assembly kit 100 comprises a temporary frame section comprising
a first stabilization member 21, a second stabilization member 22, a third stabilization
member 23, a fourth stabilization member 24, a fifth stabilization member 25, a sixth
stabilization member 26 and a seventh stabilization member 27. All stabilization members
21, 22, 23, 24, 25, 26, 27 are surrounded by the permanent frame section 10, respectively.
The stabilization members 21, 22, 23 are located in parallel to each other and in
parallel to both attachment members 13, 14. The stabilization members 21, 22, 23 are
connected between the first and second supporting members 11, 12, respectively. The
further stabilization members 24, 25, 26, 27 are located in a corner of the permanent
frame section 10 and are connected between one of the supporting members 11, 12 and
one of the attachment members 13, 14, respectively. The stabilization members 24,
25, 26, 27 are installed in an angle of 45 degrees between the supporting members
11, 12 and the attachment members 13, 14, respectively.
[0066] In Fig. 5 three stabilization members 21, 22, 23 are mounted orthogonal to the first
supporting member 11 and the second supporting members 12 within the permanent section
10. Further four stabilization members 51, 52, 53, 54 are mounted in nearby corners
of two orthogonal supporting members 11, 12, 13, 14 or in the corners of a supporting
member 11, 12 and the attachment member 13, wherein the attachment member 13 is orthogonal
to the first supporting member and the second supporting member 12.
[0067] In Fig. 5 and Fig. 6 the assembled frame assembly kit 100 comprises a plurality of
fixation devices 40 which are installed at an outer surface 15 of the permanent frame
10, especially at an outer surface of a supporting member 11, 12, which may be vertically
arranged at the installation location. The fixation device 40 is illustrated in more
detail in Fig. 7 and Fig. 8. The fixation device 40 comprises a fixation element 41
with a body having a longitudinal axis and a fastening element 42. The fastening element
42 is located in a center area of the fixation element 41, whereas the fixation element
41 is rotational movable in relation to the fixation element 41 as a rotation center.
The fixation device 40 is installed in a groove 43 of the permanent frame section
10.
[0068] The groove 43 may be a longitudinal groove which may extend from a first end of a
member 11, 12, 13, 14 to a second end of the member 11, 12, 13, 14 at the outer side
of the permanent frame section 10 as shown in Fig. 5 and Fig. 6. Several fixation
devices 40 may be installed within one groove 43 at an outer surface of the permanent
frame section 10, for example in a distance of fifty centimeters to each other or
other intervals.
[0069] Fig. 7 illustrates a fixation device 40 in a non-operating mode of the fixation device
40. Fig. 8 illustrates the fixation device 40 of Fig. 7 in an operating mode of the
fixation device 40 for fixing the permanent frame 10 into a surrounding.
[0070] Fig. 7 illustrates an exemplary embodiment of a fixation device 40 in a first position.
The fixation device 40 comprises a fixation element 41, which is mounted at an outer
frame surface of a member 11, 12, 13, 14 of the permanent frame section 10. The fixation
element 41 is fixed by a fastening element 42 in a longitudinal groove 43 of the permanent
frame section 10. The fixation element 41 has five openings 44, for example bore holes,
wherein a fastening element 42 is mounted at a center opening 44 in a central part
47 of the fixation element 41. The fastening element 42 provides fixing the fixation
device 40 rotatable inside the groove 43 in a rotation direction 55. The fastening
element 42 is mounted symmetrically to the ends of the fixation element 41, thus the
fixation element 41 has equal lengths to both sides of the fastening element 42.
[0071] In Fig. 8 the fixation element 41 is rotated by ninety degrees in one of the rotation
directions 55, clockwise or counter-clockwise, to a second position. In this position
the fastening element 42 is retaining the fixation element 41 partly in the groove
43. The outer part of the fixation element 41, not inside the groove 43 anymore, is
sticking out of the groove 43 in an angle 57. In the second position the fixation
element 41 is not able to rotate independently back to the non-operating mode of the
first position. The prevention of rotation is due to a clamping pressure between the
fixation element 41 and an edge of the groove 43 resulting in a fixing force, which
is fixating the fixation element 41 in position and ensures, that the part of the
fixation element 41, which is sticking out of the groove 43 and not able to arrive
back to a flat form without any further manipulation of a craftsman.
[0072] Fig. 9 and Fig. 10 illustrates a further exemplary embodiment of a fixation device
40, which may be utilized as an alternative of the fixation device 40 of Fig. 7 and
Fig. 8. In Fig. 9 the fixation element has a two dimensional shape in a non-operating
mode and in Fig. 10 the fixation element 41 has a three dimensional shape in an operating
mode.
[0073] In Fig. 9 the fixation device 40 comprises a fixation element 41 having a body with
a longitudinal axis. The fixation device 40 comprises a wave like manner geometry
45 at two opposite sides of the body. A plurality of openings 44 is located between
the wave like manner lines 45. The fixation device 40 in Fig. 9 comprises five openings
44, wherein in a center opening in the center of the body of the fixation element
41 a fastening element 42 is mounted. The fastening element 42 fixes the fixation
device 40 which has a two dimensional shape inside a longitudinal groove 43. The fastening
element 41 allows a rotation of the fixation element 41 of at least 90 degrees in
case the fixation element 41 is transferred into a three dimensional shape, for example
by rotating and bending.
[0074] In Fig. 9 the fixation element 41 comprises a first end and a second end, wherein
at both ends the fixation element 41 comprises a fork like manner geometry 46, which
may be utilized for mounting and fixing the permanent frame 10 onto a wall or surrounding.
[0075] Fig. 10 shows the fixation device 40 of Fig. 9, whereas Fig. 10 may also be valid
for the fixation devices 40 illustrated in Fig. 8 and Fig. 9. In Fig. 10 the fixation
device 40 is bended into a three dimensional shape, wherein the fastening element
42 is fixing a center part of the fixation element 41 inside the groove 43. The three
dimensional fixation devise 40 has a V-like shape form and is bended away from the
surface 15 of the supporting member 11, 12. The bending is performed symmetrically
in relation to the center of the fixation element 42. Therefore the length and the
angle of the bended fixation element 41 are equal, measured from its center part 47.
In Fig. 10 the left side with a left leg and the right side with a right leg of the
fixation element 41 are of identical shape. The fixation element 41 provides a first
angle 56 between the right leg and the left leg. Moreover, a second angle 57 is present
between the surface 15 and one leg of the fixation element 41. In Fig. 10 this second
angle 57 is about 45 degrees and the first angle is about 90 degrees.
[0076] In Fig. 7, Fig. 8, Fig. 9 and Fig. 10 the fixation elements 41 may be made of metal,
for example the fixation elements 41 may be manufactured from galvanized metal plates.
The fixation elements 41 may be installed and fixed by the fastening element 42 before
the frame assembly kit 100 is transported in a disassembled mode. During transportation
the fixation elements 41 may have a two dimensional shape and may be stored and embedded
completely inside the groove 43 of a supporting member 11, 12 or of an attachment
member 13, 14. During installation on site one or more fixation elements 41 on each
member 11, 12, 13, 14 may be bended and turned into a three dimensional shape for
fixing the permanent frame section 10 onto a wall or a surrounding. It may be foreseen
that at least one fixation element 41 on each supporting member 11, 12 may be utilized
for fixation.
[0077] Fig. 11 to Fig. 14 illustrates two dimensional views of exemplary embodiments of
permanent frame sections 10 with different kind of attachment member 13. The different
shapes of attachment members 13 may be attached to the first supporting member 11
and the second supporting member 12, respectively. The attachment members 13 in Fig.
11 to 14 may have a similar connecting geometry as shown for the attachment member
13 in Fig. 1 and Fig. 14. Due to the assembly character of the frame assembly kit
100 the attachment member 13 may be interchangeable. Therefore, it is possible to
adapt the permanent frame section 10 according to construction requirements and sizes
of openings to be supported by the assembled frame 10, 20. Thus, any kind of opening
may be supported by the frame assembly kit 100 in order to suit for any form of door,
window or opening. The different forms of the attachment members 13, 14 in all Figures
including a straight form in Fig. 1 to 3 may be manufactured of one part or may be
combined by two or more parts.
[0078] In Fig. 11 the attachment member 13 has an arched form. The arched form may be a
section of a circular ring or a section of an ellipse.
[0079] In Fig. 12 the attachment member 13 has a curved form comprising a horizontal section
in the center part of the attachment member 13 which horizontal section is curved
in the direction towards the attached supporting members 11, 12, respectively, in
order to provide a vertical interface geometry to be connected via a plug connection
with the supporting members 11, 12 on each end of the attachment member 13. Thus,
the attachment member 13 has a straight form with circular quadrants at the corners
towards the supporting members 11, 12.
[0080] In Fig. 13 the attachment member 13 comprises a pointed form with a peak in the middle
and two sections on both sides comprising a form of a cycle section or comprising
at least partly circular sides attached to the supporting members 11, 12, respectively.
[0081] Fig. 14 illustrates an attachment device 13 which has a semicircular form.
[0082] The geometries illustrated in Fig. 11 to 14 may be attached to a temporary frame
section 20 in a similar or identical manner as shown and described in relation to
further embodiments of the present invention.
[0083] Fig. 15 illustrates an exemplary embodiment of a first or second supporting member
11, 12. In all embodiments in relation to the present invention the supporting members
11, 12 may be manufactured of one piece of material or may be manufactured of a plurality
of pieces. The material is utilized for manufacturing is preferably wood or material
comprising wood components, such as ply wood.
[0084] In Fig. 15 the supporting member 11, 12 is manufactured of three parts or three elements
16, 17, 18, which are attached to each other for example by adhering or by clamping.
A supporting member consisting of more than one piece may be easy to manufacture.
Firstly, the shape of the female part 35 may be manufactured at all three pieces and
afterwards all pieces 16, 17, 18 are connected to each other. This provides an easy
manufacturing due to uncomplicated cutting steps. For example the middle part 17 may
be cut only in length without any need for further shaping, since the female part
35 may comprise a horizontal line at the bottom of the opening. Moreover, the second
part 17 in the middle of the supporting member 11, 12 may be of reduced height in
comparison to the first part 16 and third part 18. This may be of advantage when providing
a groove 43, which may be created by choosing different heights of the parts 16, 17,
18 without any need of further manufacturing, such as cutting.
[0085] In Fig. 15 a female part 35 is provided on the top of the supporting member 11, 12
in order to receive a male part 34 of an attachment member 13, 14 of a plug connection
31, 32. It may also be foreseen to provide a female part 35 on the bottom of a supporting
member 11, 12 in order to enable a plugging of two supporting parts to each other
on one vertical side of the assembled permanent frame section 10. This may be of advantage
in case large sizes of openings are under construction work.
[0086] In Fig. 15 the male part 34 of the plug connection 31, 32 has a corresponding geometry
in order to fit into the female part 35. The male part 34 may be inserted from a horizontal
direction into one of the vertical mounted supporting members 11, 12. The female part
34 of the plug connection 31, 32 may comprise a geometry which prevents disconnecting
the male part 35 by lifting or by moving the male part 35 in a vertical direction.
This kind of geometry may prevent unintended dismounting of the permanent frame section
10 when pressing the assembled frame assembly kit into the opening of a wall. Thus,
the plug connection 31, 32 comprises a securing mechanism without any need of further
elements or tools.
[0087] Fig. 16 illustrates a plurality of plug connections 33 between the permanent frame
section 10 and the temporary frame section 20. A first stabilization member 21 and
a second stabilization member 22 are mountable to the second supporting member 12.
The two straight stabilization members 21, 22 differ in their connection geometry.
However, it may be foreseen that all plug connections 33 connecting the permanent
frame section 10 and the temporary frame section 10 are of identical shape and size.
This has the advantage that the temporary frame section 20 may be fixed in a flexible
way without exchanging part of the permanent frame section 10. A third stabilization
member 25 extending over a corner of the permanent frame section 10 has a connecting
geometry which fits in the same recesses 35 of the permanent frame section 10 as the
straight formed stabilization member 21 comprising a dovetail connection 36, respectively.
[0088] In Fig. 16 both straight formed stabilization members 21, 22 comprise a male part
34 of a plug and socket connection 33, whereas the second stabilization member 22
comprises one part of a dovetail connection 36 corresponding to a recess 35 in the
second supporting member 12. A dovetail connection is advantageous in manufacturing,
since only two cuts may be performed in order to receive an upper section of the male
part 34 and two cuts may be performed in order to receive a lower section of the male
part 34. It may be foreseen that the body of the stabilization member 22 comprises
a same extension in vertical direction as the extension of the male part 34 in vertical
direction illustrated in Fig. 16.
[0089] In general, the frame assembly kit 100 may be utilized during a construction of a
wall. Moreover, the frame assembly kit 100 maybe utilized as an extra frame or pre-frame
for supporting a mounting of a window or a door. For this purpose, the permanent frame
section 10 may stay installed after finishing the construction work in relation to
a wall or surrounding, whereas the temporary frame section 20 may be removed after
construction work.
[0090] During construction work the temporary frame section 20 may allow a passing through
the permanent frame 10 by a person. The members of the temporary frame section 20
may be removed and plugged fast and easily. A removing of members of the frame section
20 may be not necessary when using stabilization members connected between an upper
part of the supporting member 11, 12 and an upper attachment member 13. In such a
case it might be possible that there is enough space for a person to pass through.
[0091] In case further stabilization members are mounted then some or all of them may be
removed for the time of passing through and plugging these parts again to their original
position after passing the permanent frame section 10. Since all members of the installed
frame assembly kit 100 are pluggable, assembling and disassembling is possible in
a short time without any need for further equipment or tools.
[0092] In this context "first", "second", "third", etc. in relation to elements may not
be understood as hierarchy, it should be understood only to distinguish different
elements from each other. Moreover, it should be understood that features described
in relation to one supporting member, to one attachment member, to one fixation device,
to one groove, etc. may be valid for other supporting members, to other attachment
members, to other fixation devices and to other grooves, etc, respectively.
