[0001] This invention relates to frames, more particularly but not exclusively this invention
relates to a joining system for wooden window frames.
[0002] It is usual for two adjoining members of a window frame to be joined together by
simply screwing, gluing or nailing. The joints can be unsightly and damaged by the
external environment and hence are usually covered by a cap strip or cover mould,
pinned, nailed or glued over the joint thus providing a protective and more attractive
finish.
[0003] This cap strip is usually manufactured from the same material as the window frame.
However, such cap strips can be visually obtrusive and expensive to fit.
[0004] It is therefore an aim of the present invention to provide an improved frame system
which may alleviate the aforementioned problems.
[0005] According to the present invention there is provided a frame system comprising at
least two abutting frame members forming a join, a slot being formed by the abutting
frame members wherein an elongate member is provided to fit within said slot so as
to substantially cover said join.
[0006] In an embodiment of the present invention said elongate member comprises two protrusions,
each protrusion adapted to fit within correspondingly formed slot within a frame member.
[0007] Also in an embodiment of the present invention each frame member comprises a protrusion
wherein said protrusions are provided opposite one another and are adapted to fit
within slots formed within said elongate member.
[0008] In an embodiment said elongate cover is a join cover.
[0009] In a further embodiment of the present invention said join cover comprises a rounded
side wherein, when in-situ, is externally visible.
[0010] In a further embodiment of the present invention, when in-situ, said join cover does
not extend beyond said frame members.
[0011] In another embodiment of the present invention, the frame members form the corner
of a frame system.
[0012] In a further embodiment of the present invention said frame members and said join
cover are manufactured from wood.
[0013] Also in an embodiment of the present invention said join cover fits over said join
such that when the frame members are joined together said join cover is provided over
said join in a substantially central location.
[0014] An embodiment of the present invention will be described with reference to the accompanying
drawings, in which:-
Fig. 1 is a section through a corner frame system comprising three frame members and
two joins;
Fig. 2 is a section through a frame system comprising two frame members and one join:
Fig. 3 is a magnified view of a join member inserted within a groove between two frame
members; and
Fig. 4 is another magnified view of a join cover in-situ.
Fig. 5 is a section through a corner frame system according to a further embodiment
of the invention;
Fig. 6 is an enlarged view of part of Fig. 5;
Figure 7 is a section through a further example of a frame system comprising two frame
members and one join.
[0015] Referring to Fig. 1 a frame system 10 comprises three frame members 12, 14, 16 joined
together to form the corner portion of a frame system 10. Frame portions 12 and 16
comprise channels 18, 20 which are shaped and formed to receive windows (not shown).
[0016] The frame members 12, 14, 16 abut at joins or seals 22, 24. These joins or seals
utilise a suitable method of joining the frame members such as screwing or nailing.
[0017] The frame member 14 comprises two similarly formed channels 26, 28 which correspond
with channels 30, 32 formed within frame members 12, 16. These channels 32, 26 and
30, 28 are positioned opposite one another so as to form a insert channel or groove
34 and 36. These channels 34 and 36 are shaped so as to receive a cover strip 38 shown
in groove 36 but not in groove 34.
[0018] The cover strip 38 comprises two protrusions 40, 42 which fit snugly within the grooves
28 and 30. The base portion of the cover strip 40 is substantially flat and covers
one end of join 36 although any suitable profile may be utilised. The top portion
of the cover strip 38 comprises a rounded portion 44 which provides an aesthetically
pleasing surface visible externally of the frame system.
[0019] The cover strip 38 may be slotted into place or comprise a flexible material which
enables a push fit to be achieved. Once in place, the cover strip 38 provides protection
for the join 24 from the ingress of water and other environmental hazards.
[0020] The joins 22 and 24 meet at an apex 46 and again similarly shaped channels 48 and
50 are formed within the frame members 12 and 16. A further cover strip 52 is provided
within the slot formed between the channels 50 and 48. The frame members 12 and 16
are therefore able to pivot about a second cover strip 52 so that frame members 12
and 16 may be positioned with any suitable angle from 90° to 180° therebetween at
their pivot point. The frame members 12 and 16 are formed with wedges 54 and 56 each
abutting either side of the second cover strip 52, to retain the cover strip 52 within
the slot.
[0021] Fig. 2 illustrates a further embodiment of the invention, however in this arrangement
only two frame members 58, 60 are utilised and hence only a single join 62 is required
to be concealed by first and second cover strips 64, 66. The first cover strip 64
is utilised in the same manner as shown in Fig. 1. The second cover strip 66 is mounted
within a notch formed by two corner chamfers 68, 70 of frame members 58 and 60 respectively.
The cover strip 66 is mounted within the notch formed by these abutting frame members
58 and 60 at their chamfered ends. The ends 72, 74 of the cover strip 66 are mounted
in correspondingly shaped slots 76, 78 formed within frame members 58 and 60 respectively.
This cover strip 66 is mounted in a notch rather than a substantially rectangular
slot as is the case with cover strip 64.
[0022] Fig. 3 shows a further embodiment of the present invention. Again a join 80 is covered
by cover strip 82 mounted within notch 84 formed by chamfered corners 86, 88 of frame
members 90 and 92 respectively. In this embodiment of the invention cover strip 82
is substantially hemispherical in shape and slots into notches 94 and 96 formed within
frame members 90 and 92 respectively. Fig. 4 shows a further envisaged shape of a
cover strip 98 mounted similarly in a shaped slot 100.
[0023] Now referring to Figures 5 to 7 further embodiments of the invention are shown. The
frame system is similar to those shown in Figures 1 and 2. In each of the embodiments
shown in Figures 5 to 7 the cover strips are formed with indentations 102, 104 which
cooperate with protrusions 106,108 formed in the frame members 12, 14, 16, 58 and
60.
[0024] The cover strips shown in the embodiments of the present invention may be manufactured
from any suitable material, usually of the same material as the frame members such
that an aesthetically pleasing external appearance is provided. Also it is desirable
but not essential, that the cover strips do not extend beyond the profile of the frame
members so as to further enhance the aesthetic appearance of the frame structure.
