[0001] The invention relates to a set of door fittings, such as door handle rosettes, the
set comprising a first fitting, a second fitting and at least one fixing arrangement
with a corresponding screw for the mounting of the fittings on two opposed sides of
a door, the fixing arrangement having the form of a hollow leg with a first end surface
and a second end surface for abutment against each of the fittings, respectively,
the area at the first end surface being receivable around a stub on the first door
fitting, said stub having a threaded hole for screwing in of a thread of the screw,
the second door fitting having a mounting hole for insertion of the screw so that
a head of the screw abuts the second door fitting around the mounting hole. The set
of door fittings is characterized in that the screw is a trap-screw and under its
head has a further head in the form of a so-called trap which by screwing in of the
screw to its mounted position enters the hollow leg of the fixing arrangement at its
second end surface and thereby expands the fixing arrangement.
[0002] The invention also relates to a method of mounting a set of door fittings, such as
door handle rosettes, on opposed sides of a door, the set comprising a first fitting,
a second fitting and at least one fixing arrangement with a corresponding screw having
a head, the fixing arrangement having the form of a hollow leg with a first end surface
and a second end surface for abutment against each of the fittings, respectively,
whereby the fixing arrangement with the area at its first end surface is placed around
a stub on the first door fitting, the first door fitting is placed on a first side
of the door so that the fixing arrangement extends through a hole in the door, the
second door fitting is placed on a second side of the door and the screw is inserted
through a mounting hole in the second door fitting, inserted through the hollow leg
of the fixing arrangement and screwed into a thread of the stub on the first door
fitting. The method is characterized by that a further head in the form of a so-called
trap placed under the head of the screw, which has the form of a trap-screw, by screwing
in of the screw to its mounted position enters the hollow leg of the fixing arrangement
at its second end surface and thereby expands the fixing arrangement to abutment against
the wall of the hole in the door.
[0003] In connection with the mounting of door fittings and the like, it is a problem with
the known solutions that these require that the hole which is drilled in the door
corresponds substantially to the diameter of the thread on the screw in order that
there shall not be too loose a fit, and so that the screws do not work themselves
loose with time. It is customary, however, that the tradesmen carry out a pre-drilling
of a hole in the door, and for this hole to be substantially larger than the actual
diameter of the screw, which means that a loose fitting takes place and that the screw
will work itself loose with time. The solution to this will thus be to produce the
fittings in different sizes, so that the stubs provided on the fittings correspond
substantially to the diameter of the drilled hole. However, this would give rise to
a relatively large stock of products.
[0004] Moreover, such a solution does not allow for the fact that when a tightening is effected,
the two sides of the door move towards each other, in that there is no internal counter-resistance.
Furthermore, it can be difficult to engage the stub by means of the end of the thread
on the screw.
[0005] From DE-A-2,837,614, a mounting of door fittings is known where the mounting units
constitute an integrated part of the door rosettes, and where the fitting of the mounting
units and herewith the door rosettes is carried out individually depending on the
thickness of the door.
[0006] Moreover, the mounting units are configured in a stiff, non-expandable material,
which means that the pre-drilling must be effected with great accuracy.
[0007] A fixing arrangement for door rosettes and the like is known from German patent publication
no. 2,615,322. In this publication, the fixing arrangement consists of two or three
parts made of a plastic material, which are put together to form an assembled plastic
part. The arrangement comprises several loose parts, which means that it is difficult
and troublesome to assemble in connection with the door rosette. Moreover, it is not
possible to effect an expansion of the plastic part and thus ensure that this sits
firmly in the hole drilled in the door. Furthermore, it is only in those cases where
all three parts are assembled that the plastic part will serve as a bracing stay,
in that in its normal two-part version, where only one plastic part sits in each side
of the door, no rigidity is achieved around the door handle fixture. In these cases
there will therefore be a distinct "sponge effect" when a tightening of the plates
towards each other is effected.
[0008] DE 94 18 266 U describes a set of two door fittings, of which one has prefitted sleeves
with internal thread, and of which another has mounting holes corresponding to the
sleeves and intended for the insertion of screws, which by the attachment of the fittings
on either side of a door are screwed into the sleeves. By the attachment, bushings
are placed around each sleeve and fitted tight in corresponding through-going holes
in a lock case mounted in a recess in the door, whereby the door fittings are fixed
securely in relation to the lock case, which in turn is secured in the door.
[0009] It is the object of the present invention to provide a method which ensures control
of the mounting screws, so that these enter into direct engagement with the threaded
stubs on the one door handle rosette, and also that a good bracing arises as a consequence
of the plug or fixing element extending in a continuous manner in the whole breadth
of the door handle, and where by tightening an expansion of the plug takes place,
so that the plug sits immovably firm in the drilled hole. It is also achieved that
it is easy to "catch" the opposite side, in that the flexibility of the plug makes
it possible to follow the holes, even though these do not extend in a straight line
and/or at right-angles to the surface of the door.
[0010] According to an embodiment of the method, on two opposite sides of a door leaf/door
plate, in which door leaf/plate there is drilled at least one through-going hole,
and comprising a fixing arrangement consisting of an elastic expandable material and
comprising a hollow leg with a first outer diameter and with a first inner diameter
in the formation of a cavity in the whole longitudinal axis of the leg, said leg terminating
at each end in a first and a second end surface, at least one fixing arrangement with
its one end part is placed on and surrounds a threaded stub provided on the one door
fitting, and the door fitting is subsequently placed on the one side of the door with
the fixing arrangement(s) in the holes provided in the door, and on the opposite side
of the door is placed the second door fitting/the second rosette comprising mounting
holes through which a trap-screw is inserted, said trap-screw sliding into the inner
cavity of the fixing arrangement.
[0011] In connection with the use of the fixing arrangement, there is thus first carried
out a clamping of the conical end of the fixing arrangement on the threaded stub which
sits on the rosette, either integrated herewith or disposed loosely in a hole arranged
for this purpose in the rosette. After this has been pressed in, the complete rosette
is now set in place in the holes which are in the door. It is ensured that the length
of the fixing arrangement corresponds to the thickness of the door, which can be done
by cutting the fixing arrangement to a suitable size. It is thus characteristic that
the fixing arrangement is a loose unit, for which reason the door fittings are produced
smooth with holes for mounting, including mounting of thread-stubs, or with at least
one integrated thread-stub on at least the one door fitting.
[0012] A rosette is then mounted from the other side, and a screw is now inserted through
the holes in this rosette. The screw used is a so-called trap-screw, which is characterised
in that it has at least a thread in the one end, and under the head at the other end
it has a further head with a diameter which is less than the outermost head, but still
larger than the thread on the screw. This trap-screw is inserted into the fixing arrangement,
and when it meets with resistance, a screwing-in is effected. It is thus easy to engage
the threaded stub on the other door rosette as a consequence of the screw being guided
via the fixing arrangement. The screw is screwed in to the bottom, and in that the
screw is configured with said under-head, which is designated a "trap", an expansion
of the walls of the fixing arrangement occurs, whereby these will expand out against
the limiting surfaces of the hole. It is hereby ensured that the screw sits firmly
in its attachment. Due to the through-going extent of the fixing arrangement, it is
also ensured that a bracing between the door plates is effected.
[0013] It is thus important that the leg in the other area has an outer diameter which exceeds
the rest of the fixing arrangement, in that this ensures that the part which is placed
over the stub and is subsequently inserted in the pre-drilled hole, sits tightly between
the surrounding walls of the hole and the outer walls of the stub itself.
[0014] It is also important that the fixing arrangement is a loose unit, i.e. it is not
integrated with the door fittings.
[0015] By providing a method according to the invention and further being characterized
by that after a certain movement through the cavity, the trap-screw is screwed in
and cuts a thread on the inside of the fixing element, it is achieved that a locking
of the screw occurs at the moment it cuts a thread in the elastic material before
it is screwed firmly in the primary thread in the threaded metal stub on the opposing
side.
[0016] By providing a method according to the invention and further being characterized
by that, when it is screwed in, the trap-screw with its trap part expands the second
end part of the fixing element into abutment with the inner surfaces of the hole,
it is achieved that an expansion of the fixing arrangement occurs, in that the trap
on the screw is drawn into the fixing arrangement by the screwing-in of the screw,
whereby an expansion of the material occurs which is pressed and lies tightly between
the walls of the hole and the outer surface of the trap itself.
[0017] As discussed earlier, the invention also concerns a fixing arrangement as disclosed
in the introduction, and where the leg in the one end area - the plug-stub area -
has an outer diameter which exceeds the first outer diameter, said plug-stub area
extending from the first end surface of the fixing arrangement and for a given distance
from this surface. The fixing arrangement is particularly suitable for use in connection
with the method as described above.
[0018] By configuring the fixing arrangement according to the invention and the fixing arrangement
for the mounting of door fittings, for example door handle rosettes, consisting of
an elastic expandable material comprising a hollow leg with a first outer diameter
and with a first inner diameter in the formation of a cavity along the whole longitudinal
axis of the leg, said leg terminating at each end in a first and a second end surface,
and being characterized in that the leg in the one end area - the plug-stub area -
has an outer diameter which exceeds the first outer diameter, said plug-stub area
extending from the first end surface of the fixing arrangement and for a given distance
from this surface, it is further achieved that the mounting of the door fitting adapts
itself to the holes pre-drilled in the door plate, so that only a small product range
of both fittings and fixing arrangements is necessary.
[0019] By providing the fixing arrangement according to the invention and further characterized
in that the cavity comprises a second inner diameter which is smaller than the first
inner diameter, said second inner diameter extending in an area at a distance from
the end surfaces of the fixing arrangement, there is achieved the forming of an area,
the so-called thread-lock, where the result of the narrowing-down is that the screw
will cut a thread in the elastic material.
[0020] The inner diameter of the plug-stub area may be larger than the inner diameter of
the remaining part of the cavity, and the inner cavity of the plug-stub area may be
conical with the largest diameter towards the end surface.
[0021] The leg may on its outer surface be provided with with at least one longitudinal
fluke which extends parallel with the longitudinal axis.
[0022] By providing the fixing arrangement according to the invention, it is achieved that
the plug-stub area has some dimensions which are suitable in connection with the pressing-on
of the stub of the door handle/rosette. By providing the fixing arrangement according
to the invention, with these flukes it is achieved that the fixing arrangement is
prevented from turning when the screw cuts a thread in the thread lock itself. It
is expedient for four longitudinal flukes to be provided, these being disposed with
90° displacement on the outer surface of the fixing arrangement.
[0023] The invention will now be explained in more detail with reference to the drawing,
where
Fig. 1 shows a longitudinal section through a fixing arrangement according to the
invention,
Fig. 2 shows a sectional view of the fixing arrangement shown in fig. 1 placed in
a door, and in which fixing arrangement a trap-screw is mounted,
Fig. 3 shows a fixing arrangement according to the invention seen from the one end.
[0024] Fig. 1 shows a fixing arrangement 1 produced in an elastic and expandable plastic
material, for example nylon. The fixing arrangement comprises a leg part 2 formed
as a cylinder and with an outer diameter 6 and an inner diameter 5, said inner diameter
5 forming a cavity 9 into which a screw can be inserted. The leg part 2 of the fixing
arrangement terminates in a second end surface 12 which extends substantially at right
angles to the longitudinal axis of the leg part. The leg part continues over in a
plug-stub part 10 which is similarly cylindrical in configuration, but its outer diameter
exceeds the first outer diameter 6. The inner diameter of the plug-stub part 10 is
similarly larger than the first inner diameter 5, and is preferably conical in configuration
with the largest diameter facing towards its end surface, i.e. the first end surface
11. This end surface extends parallel with the second end surface 12.
[0025] By configuring the plug-stub part as described, it is ensured that its outer diameter
lies against the hole which is drilled in the limiting, surrounding surfaces of a
door, and that the inner part is such that it fits the stub which is fastened to a
door rosette/fitting.
[0026] The fixing arrangement also comprises an area in the leg part 2 which has a smaller
diameter than the inner diameter 5, this inner diameter 13 being preferably 0.3 mm
smaller. There is hereby formed a lock part, i.e. that when the screw is inserted
in the fixing arrangement via the cavity and starting from the second end surface
12, the screw will meet with resistance when it reaches the thread-lock part 4, which
means that when the screw is rotated, the cutting of a thread is effected in the inner
surface of the thread-lock part.
[0027] Fig. 3 shows a cross-section of the fixing arrangement 1 shown in fig. 1 seen from
the one end, and where it will be seen that its outer surface is provided with so-called
flukes 7, preferably four in number, which extend parallel with the longitudinal axis
of the leg part and are displaced 90° in relation to one another. With these flukes
it is prevented that the fixing arrangement turns when the screw cuts the thread in
the thread-lock 4.
[0028] Fig. 2 shows the fixing arrangement 1 when this is mounted in a door, and thus the
figure shows two door plates 14 extending in parallel and through which at least one
hole 15 has been drilled, and where on the outer side of each door plate there is
a door fitting 8, for example in the form of a door rosette. The diameter of the hole
is typically in the order of 8 mm. A lock-casing 20 is inserted between the door plates.
The mounting is carried out in that the one door rosette, on its surface facing towards
the door plate 14, is provided with at least one threaded stub 3, and the fixing arrangement
1 is pressed with its plug-stub part down over the thread-stub part, so that this
sits firmly on the rosette.
[0029] The door rosette with the legs is now inserted in the holes arranged for this purpose
in the sides of the door plates 14, and from the other side a correction of the leg
length is carried out, in that this leg part 2 is cut off so that it corresponds to
the thickness of the door. Hereafter, the second door fitting 8 is mounted, this having
holes in which two screws are placed. As a consequence of the fixing arrangement 1
extending the whole of the way through the door, in connection with the mounting it
is easy to guide the screws directly into engagement with the threaded stubs on the
opposite fitting, in that the inner cavity of the fixing arrangement 1 serves as a
guide.
[0030] When the screw meets with resistance, in that it has now reached the thread-lock
part 4, it is screwed in, and by this screwing-in a thread is cut in the inner surface
of the fixing arrangement. The screw is screwed in right to the bottom. In that a
so-called trap-screw is used for the mounting, it is ensured that the area at the
second end surface 12 of the fixing arrangement 1 expands in such a manner that the
leg parts are pressed out into abutment with the surrounding surfaces of the hole.
It is hereby ensured that the fixing arrangement etc. sits firmly without any risk
of the screw working itself out. Here it is important that use is made of a so-called
trap-screw 16, which is characterised in that the axis part comprises a tread part
17, and where the head part 18 in the area under the head has a so-called trap 19,
said trap being characterised in that it has a diameter which is larger than the diameter
of the thread itself, but is smaller than the actual head part.
[0031] The plug thus serves as a bracing stay, in that it increases the rigidity around
the door handle fitting, and particularly in connection with doors of steel plate
there is a distinct sponge effect which is prevented by the present invention.
[0032] The effect of the fixing arrangement is thus that the mounting of the fitting adapts
itself to the holes which are pre-drilled in the door plate, said holes lying typically
around 8 mm old. The dimensions of the plug are thus preferably a length of approx.
75 mm, which is adapted to the relevant door thickness, an outer diameter 6 of 5.3
mm and an inner diameter 5 of 3.9 mm which, however, at the thread-lock lies at around
3.7 mm old. The length of the actual plug-stub part is preferably 11-12 mm, and it
has an inner diameter of 5.1-5.7 mm, in that as mentioned the diameter is changed
when the inner cavity of the plug-stub part is conical in shape. The fixing arrangement
available for use with standard doors of 40 mm has a length just under 40 mm.
[0033] The flukes provided on the outer surface of the fixing arrangement 1 have a thickness
which is typically 0.75-1 mm, and a height of approx. 0.2 mm. These are provided on
the external side of the plugstubs.
[0034] The plug can be used both in connection with "loose" polygon thread-stubs which are
secured by polygon-shaped holes in the door handle plate/rosette, or in connection
with bolt-welded thread-stubs.
[0035] The effect of the plug as spacing stay in "soft door types" with only slight inner
counter-resistance, e.g. steel plate doors, is certainly not unimportant. In practice
the stay effect is obvious. The problem with "soft doors" is known to those familiar
with the art.
[0036] By expansion of the leg of the plug, a dish-shaped distension is formed around the
screw's "trap", and this lies up against the rear of the door handle plate/rosette,
so that the plug, stiffened by the screw, forms a through-going spacing stay which
effectively prevents that the mounting of door fittings with through-going screws
gives rise to an undesired partial pressing together of the opposing sides of the
door plates.
[0037] In the mounting of door fittings with through-going screws, it is a known fact that
it is difficult to get the ends of the screws to engage with the threaded-stub on
the opposing side, especially in the case of thick doors. The configuration of the
plug according to the invention with through-going plug leg affords the advantage
that the through-going mounting screws are led directly into the opposing thread-stubs.
This provides convenient mounting, and is not without significance with regard to
the mounting time, which seen from the tradesman's point of view is a part of the
product price.
