Abstract

A joint in a window frame is formed by locating a connector 10 in a channel or rebate cut in one frame member e.g. a sill and inserting the other frame member into the connector which is internally shaped to correspond to its external profile. The connector of Figure 1 is used to join a cill to a jamb or mullion and that of Figure 5 to join a transom to a jamb or a mullion. <IMAGE>

Description

SPECIFICATION Window frame This invention relates to frames used in buildings and more particularly wooden window frames.

A rectangular window frame includes a cill, a head and two jambs. It is normal practice for the jambs to be morticed at each end into the head and cill. The shaping on the surface of the head and cill against which the jambs abut requires the jambs to be correspondingly shaped. This shaping of the jambs adjacent the mortice joints with the head and cill has always required a certain degree of skill so that construction of window frames in the traditional way is usually beyond an unskilled "do-it-yourself" enthusiast. The same problem arises in fitting a transun or lintel to a window frame and in the construction of a sash.

The present invention has been made from a consideration of this problem.

According to the invention there is provided a window construction wherein the connection between two parts of said window construction comprises a member received in an appropriately sized channel or rebate in one part, the member being internally shaped to correspond to the external shape of the other part which is received in said channel member.

In a preferred embodiment of the invention the member is of substantially rectangular external section so that only a simple rectangular section channel or rebate needs to be formed in the said one part for reception of the member. Preferably the member defines a channel and is also profiled, on the side thereof which defines an exposed part of the window so as to be flush with the adjacent surface of the window construction so that, once painted, the member cannot readily be seen in the finnished product.

The member can be made of any suitable material but is preferably made of plastics.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 is a plan view of member for use in the invention; Figure 2 is an end view of the member of Figure 1 in the direction of arrow A; Figure 3 is a side view of the member of Figure 1 in the direction of arrow B; Figure 4 is an end view of a cill; Figure 5 is an end view of a jamb; Figure 6 is a plan view of another member for use with a transom; Figure 7 is an end view of a transom.

Figure 8 is a plan view of a member used for a sash and Figure 8a is an end view of the profiled timber used for making a sash.

Figure 9 is a side view of the exterior of a part of a sash incorporating the member of Figure 8.

Referring to Figures 1 to 3 of the drawings a channel member comprises a base 10 with walls 12 and 14 on two opposite sides. Side 12 is of uniform height and thickness and extends along the full length of the base 10. A wedge shaped boss 16 projects into the channel defined by walls 12, 14 from substantially the mid point along wall 12.

Wall 14 extends over about 2/3 of the length of the base 10. The wall is of gradually decreasing height, in the direction towards the upper edge of the base (as viewed in the drawing). As the wall 14 decreases in height it increases in width as can be seen in Figure 1.

A rectangular cut-out 18 is provided in the base at the part thereof over which wall 14 does not extend.

To form a window frame using the channel member a channel is formed, for example, in a ciil as shown in Figure 4. The channel in the cill is indicated by the dotted lines 20 and is cut in the upper shaped surface 22 of the cill down to a depth level with the glazing rebate 24.The channel member is then secured in the channel as by screws through apertures 26 in the base 10. When the channel member is in place the upper surface of wall 14 is flush with the upper surface 22 of the cill.

A jamb of the section illustrated in Figure 5 can now be received in the channel member. By comparison with the end view of the jamb and the area defined by the inner surfaces of walls 12 and 14 it will be seen that they correspond. Thus the boss 16 is received in groove 30 in the jamb, the wall 12 lies along the sides 32 and 34 of the jamp on either side of groove 30 and the wall 14 follows the shaped surface 36 of the jamb.

A window frame can be very quickly made by positioning another channel member in the cill at the desired location and two more channel members in the head. It will be appreciated that by using the invention a window frame of any dimensions can be made.

If a transom is required to extend across the window the channel member of Figure 6 can be used. This channel member is the same as that of Figure 1 except that instead of wall 12 and boss 16 a mirror image of wall 14 is provided, referenced 14'. The space defined between walls 14 and 14' corresponds to the section of a transom 40 as shown in Figure 7.

The channel member of Figure 6, in use, is placed in a channel indicated by the dotted lines 42 marked on the side of the jamb in Figure 5. As with the cill (and head) the channel is cut to the depth of the glazing rebate 44 in the jamb so that when the channel member is in position the walls 14 and 14' are flush with surface 36 of the jamb.

It will be appreciated that by using the channel member of Figure 6 in the cill and head one or more mullions, having a section similar to that of the transom 40 of Figure 7, can be included in the window construction. The mullions can themselves be fitted with members to accept transoms and so forth.

For fixing the corner of a sash the member 50 illustrated in Figure 8 can be used which comprises a base 51 having a wall 52 along one edge thereof.

The base area corresponds to the cross-sectional area of the inner part of 54 latched in Figure 8a of the profiled timber from which the sash is formed.

The inner wall surface is profiled as at 56 to correspond to the surface 58 of the profiled timber.

To form a sash joint a rebate is formed at the end of one piece of timber 60 to a depth equal to the depth of area 54. Member 50 is fixed to the face 54 as by screws which extend through apertures 53 in the base. A corresponding rebate is formed in a secured piece of timber 62 and the two pieces put together as shown in Figure 9 with the profiled surface 58 of the second piece of timber 60 being received in the correspondingly shaped member 50. The joint can be secured by adhesive and, if desired, screws or other like fastening means 66 extending through the flange part 64 of the rebate at the end of the first piece of timber 60 into the second piece of timber 62.

The invention is not restricted to the above described embodiments and many variations are possible. For example by altering the inner surfaces of walls 12, 14 and 14' appropriately, any shape of jamb, mullion or transom can be made up with a cill and a head into a window.
