[0001] This invention relates to a method and means for securing a frame member such as
a door frame or lining, window frame and the like to a wall or similar surface defining
an opening for the frame member.
[0002] Internal door linings and window frames are normally fixed in place within openings
defined by walls or similar surfaces, by means of any suitable securing means such
as nails or screws, which are normally hammered or screwed through the frame into
the wall or similar surface. Because of imperfections in construction of the wall
or similar surface defining the opening, it is often necessary to pack any space or
gaps between the frame and the wall face of the opening, with packing pieces of for
example timber, to compensate for such imperfections in construction, thereby avoiding
distortion of the frame or lining during the fixing process.
[0003] It is extremely difficult to ensure accurate, location of the frame or lining in
the opening by this crude method of fixing. Adjustment of the frame or lining with
respect to the wall defining the opening can also be a time consuming operation, and
fixing of the frame or lining can sometimes result in damage to the frame or lining
necessitating additional filling and finishing operations to be performed on the inside
surfaces of the lining or frame member.
[0004] It is an object of the present invention to provide a method and means of securing
a frame or lining to a wall or like surface defining an opening for the frame or lining
incorporating a device which combines the operations of adjusting the frame or lining
to the correct position with respect to the wall or similar surface, and secures the
frame or lining in the adjusted position, to the wall or similar surface, rendering
any further fixing or finishing operations unnecessary at the same time achieving
greater accuracy than with previously known methods.
[0005] According to one aspect of the invention there is provided a frame member securing
device serving the dual function of both adjusting the position of a frame member
with respect to a wall surface defining an opening for the frame member, and of permanently
fixing the frame to the wall surface, the device comprising at least one externally
threaded member connected to or formed integrally with a planar member extending normal
to the longitudinal axis of the or each externally threaded member, and arranged to
engage in means formed in the frame member or secured to or formed integrally with
the frame member, the or each planar member being arranged to be secured to a wall
surface normal to the wall surface arranged to be fixed to the said frame member,
and the or each externally threaded member engaging in said means such as to fix the
frame member to the wall and allow the position of the frame member to be adjusted
relative to the wall by relative movement of the or each externally threaded member
and the means engaged thereby, the combination and interengagement of planar member,
externally threaded member and said means allowing both the position of the frame
member to be adjusted in two planes, and the frame member to be permanently secured
to the wall surface.
[0006] According to another aspect of the present invention there is provided a frame member
securing device for securing a frame member to a wall surface defining an opening
for the frame member and comprising at least one open-ended tubular member internally
threaded at at least one end and formed integrally with or arranged to be secured
to the outer surface of the frame member intended to be fixed to the said wall surface,
and a complementary externally threaded member for the or each internally threaded
end of the at least one tubular member, the or each externally threaded member being
connected to or formed integrally with a planar member extending normal to the longitudinal
axis of the or each externally threaded member, the or each planar member being arranged
to be secured to a wall surface normal to the wall surface arranged to be fixed to
the said outer surface of the frame member, and the or each externally threaded member
engaging in the respective internally threaded end of the respective tubular member
such as to fix the frame member to the wall and allow the position of the frame member
to be adjusted relative to the wall by rotation of the or each externally threaded
member in the respective ends of the respective tubular member fixed to or formed
integrally with the frame member.
[0007] In practice, at least three such tubular members would be fixed to the outer surface
of the frame member allowing adjustment and fixing at the top, middle and bottom of
the outer surface of the frame member.
[0008] According to a further aspect of the present invention there is provided a method
of securing a frame member to a wall surface defining an opening for the frame member
comprising the steps of securing at least one open-ended tubular member, internally
threaded at at least one end, to an outer surface of the frame member, or forming
the said at least one tubular member integrally therewith, providing for the or each
internally threaded end, an externally threaded member connected to or formed integrally
with a respective planar member, locating the or each externally threaded member in
its respective internally threaded end of the tubular member, securing the or each
planar member to a surface of the wall extending normally to the surface of the wall
arranged to abut the outer surface of the frame member, and adjusting the position
of the frame member with respect to the wall by rotation of the or each externally
threaded member in a respective internally threaded end of the tubular member to correctly
align the frame member with respect to the wall and couple the frame member to the
wall.
[0009] The invention will now be described by way of example only with particular reference
to the accompanying drawings, wherein:
Figure 1 is a plan view of the fixing device of the present invention for fixing a
frame member to a wall;
Figure 2 is a plan view of an externally threaded member and planar member of the
device of the present invention;
Figure 3 is a side elevation of the externally threaded and planar members of Figure
2;
Figure 4 is a perspective view of one construction of an internally threaded member
of the fixing device of the invention;
Figure 5 is a plan view of a different construction of internally threaded member;
and
Figure 6 is a plan view of a modified form of fixing device in accordance with the
present invention where the means formed in the frame is a pre-drilled hole.
[0010] Referring particularly to Figure 1, in order to secure a frame member 1 to a surface
2 of a wall 3 defining an opening in which the frame member is to be located, there
is provided a tubular member 4 internally threaded at each end as shown in Figure
1 and arranged to be fixed to the outer surface of the frame member 1 by securing
means 5. In Figure 1 an architrave for a door frame is shown at 1A and plaster 1B
is shown between the architrave and wall surface 3. One form of internally threaded
tubular member 4 is shown in Figure 4, wherein a rectangular section member 6 is provided
with a tubular portion having an internal screw thread 7 at each end and provided
with a series of holes 5a to accommodate fixing means (not shown) to allow the rectangular
section member 6 to be secured to the outer surface of the frame member 1. A modified
internally threaded member 4 is shown in Figure 5 in which the fixing means 5b are
shown.
[0011] The second component of the frame fixing and adjustment device of the invention consists
of an externally threaded member and associated planar member for each respective
internally threaded end 7 of the tubular member 4. Thus, as shown in Figures 1 and
2 in particular, each planar member 8 is formed integrally with an externally threaded
portion 9 arranged to engage in the respective internally threaded end 7 of the tubular
member 4 as shown in Figure 1. By engaging the externally threaded members 9 in the
respective internally threaded ends 7 of the tubular member 4, and rotating the externally
threaded member with respect to the internally threaded member, the position of the
frame member 1 with respect to the wall 3 can be adjusted and the frame member 1 fixed
to the wall 3 in the correctly aligned adjusted position required.
[0012] To locate the frame member 1 in a correct aligned position with respect to the wall
3, it is first necessary, prior to placing the frame member 1 within the wall opening,
to fix a plurality of said internally threaded members 4, preferably three, on the
outer surface of the frame member intended to abut the surface of the wall adjacent
the opening. The internally threaded members 4 are arranged parallel to and, preferably
at the top, middle and bottom of the frame member. The length of each tubular member
4 is such that the ends thereof are slightly inset from the surfaces 2a, 3a, of the
wall when the frame is affixed thereto as shown in Figure 1. The lining or frame 1
is placed as near as possible in the correct position in the opening and the externally
threaded portions located in engagement with the complementary threaded portions 7
of the tubular members 4, secured to the frame or lining 1. The externally threaded
members are screwed into the respective internally threaded members until the planar
portion 8 associated with each externally threaded portion 9, is flush with the wall
surfaces 2a, 3a.
[0013] The lining or frame 1 is then adjusted in two different planes. Firstly, the lining
or frame is adjusted in a fore and aft plane to an intermediate position, following
which the planar portions 8 are secured to the respective wall surfaces 2a, 3a, by
securing means 8a such as masonry nails. Adjustment in the second or transverse plane
is effected by adjusting the position of the externally threaded members in their
respective female internally threaded counterparts, either by screwing or unscrewing
the externally threaded member in their respective internally threaded members. The
lining of frame 1 is thus firmly fixed to the wall by means of the planar members
and by the interengagement of the internally and externally threaded members with
adjustment in both planes to the correct aligned position required and without damage
to the surfaces of the lining or frame members. It will be appreciated that the invention
is applicable to the fixing of any planar member or surface to a second planar member
or surface and is not limited to the fixing of door linings and window frames to walls.
For instance, a first planar member or surface can be secured to a second planar member
or surface by fixing at least one tubular member having at least one internally threaded
end to the first planar member or surface, and by engaging an externally threaded
member in a respective internally threaded end of said at least one tubular member,
and securing the planar portion of the or each externally threaded member, to the
second planar member or surface.
[0014] The advantages of the device of the present invention are that the frame member or
lining can be fixed to a wall and adjusted to the correct aligned position with respect
to the wall, and can be re-fixed in place if necessary without damage to the lining
or frame member. The lining or frame can be adjusted to the correct aligned position
with respect to the wall much more easily and with a greater degree of accuracy than
with previously known arrangements, and the tubular members by acting as a brace across
the width of the lining or frame member, serve to strengthen the lining or frame,
which with previously known arrangements, often bows and twists during and after fixing
and plastering of the wall.
[0015] Although the drawings illustrate the internally threaded tubular members 4 fixed
to the outer surface of the frame 1 by securing means 5, it will be appreciated that
the internally threaded tubular members may be formed integrally on the outer surface
of the frame member.
[0016] Furthermore, the internally threaded tubular members may be dispensed with as shown
in Figure 6. The frame member is pre-drilled to accept an externally threaded member,
such as a screw incorporated within the planar member 8.
[0017] Although the drawings illustrate the tubular members as being internally threaded
it will also be appreciated that the tubular members may be formed without threads
but in such a manner that they will accept an externally threaded member such as a
screw incorporated within the planar member 8.
