Abstract

A frame joint is described comprising two frame members (1 and 2) cut to form a mitred joint. The mitred ends are formed with grooves (3) which when placed adjacent one another form an aligned slot. A connector member (4) is hammered or pushed into the slot to form a rigid and reliable corner frame joint. The connector member (4) is made of metal or rigid plastics material and has a curved nose portion (5) at one end joined by a flat end face (6). Each side of the connector (4) has two grooves (7) with parallel inner walls (8) and diverging outer walls (9) formed in the side surfaces of the connector. Ribs (10, 11) with angled ends (12, 13) run along the outer walls (9). The end of the connector opposite to the round nose portion (5) is cut to a V-shape corresponding to the angle shape of the mitred frame members (1 and 2).

Description

A FRAME JOINT This invention relates to a joint for connecting two frame members, and more particularly but not exclusively for joining two wooden window frame members. Various forms of joints have been proposed for joining corner joints of window frames. These require careful machining and subsequent fixing by means of glue or screws.
An aim of the present invention is to provide a joint for connecting two frame members which is of simple and reliable construction.
According to one aspect of the present invention there is provided a frame joint for connecting two adjoining frame members, each member being formed with a groove which when the members are placed adjacent one another form an aligned slot, a connector member for insertion in the slot, wherein the connector member has a curved nose portion and two ribs at least on one side of the connector member which diverge towards the curved nose portion.
Preferably the connector has two longitudinal grooves extending along the length of the connector member on each side thereof. Conveniently, the opposite end of the connector member to the rounded nose portion is cut to an angled V- shape. The connector member may also be of different lengths for use with different width frame members. In a preferred construction the grooves in the frame members have curved ends corresponding to the curved nose portions of the connector member.
According to a second aspect of the present invention there is provided a method of assembling the frame joint as set fourth above, comprising forming a groove in the ends of two members so that they form a slot when positioned with the grooves adjacent one another, and inserting a connector member in the slot.
An embodiment of the present invention will now be described by way of example only, with reference to the accompanying drawings, in which:
Fig. 1 is a perspective view of two frame members cut to form a mitred joint;
Fig. 2 is a side elevation and end view of a grooved frame member shown in Fig. 1;
Fig. 3 is an elevation of a connector member shown in Fig. 1; and
Fig. 4 is a plan view of the connector member shown in Fig. 3. The frame joint illustrated comprises two frame members 1 and 2 which are cut at one of their ends to form a mitred joint. Each mitred cut end is formed with a groove 3 which when placed adjacent one another form a slot. A connector member 4 is hammered or punched in the slot to form a rigid and reliable corner frame joint.
The grooves 3 are curved at one end to form a blind end as shown in the frame member 1 in Fig. 1 and in dotted line in Fig. 2. The connector member 4 is preferably made of metal but may be made of a rigid plastics material. The connector member has a curved nose portion 5 at one end joined by a flat end face 6. Each side of the connector member have two grooves 7 with parallel inner walls 8 and diverging outer walls 9 formed in the side surfaces of the connector. Along the outer walls 9 are ribs 10 and 11 with angled ends 12 and 13. The end of the connector opposite to the round nose portion 5 is cut to a V-shape to correspond to the angled shape of the mitred frame members 1 and 2.
The method of assembling the frame members is as follows: Each frame member is cut at an angle to form a mitred joint with a groove, the two grooved ends are placed together to form a slot into which the connector member is hammered or punched. The diverging ribs form grooves in the frame members and displace the wooden member into the grooves. The curved nose portion abuts against the curved end of the grooves aligning the V- shaped end of the connector with the angled inner walls of the mitred frame members. The diverging ribs on the connector member engage the frame members pulling them together to produce a very strong secure joint.

Claims

CLAIMS:
1. A frame joint for connecting two adjoining frame members, each member being formed with a groove which when the members are placed adjacent one another form an aligned slot, a connector member for insertion in the slot, wherein the connector member has a curved nose portion and two ribs at least on one side of the connector member which diverge towards the curved nose portion.
2. A frame joined as claimed in Claim 1, wherein the connector member has two longitudinal grooves extending along the length of the connector member on each side thereof.
3. A frame joint as claimed in Claim 1 or 2, wherein the opposite end of the connector member to the rounded nose portion is cut to an angled V-shape.
4. A frame joint as claimed in any preceding claim, wherein the connector member is of different lengths for use with different width frame members.
5. A frame joint as claimed in any preceding claim, wherein the grooves in the frame members have curved ends corresponding to the curved nose portions of the connector member.
6. A method of assembling the frame joint as claimed in any preceding claim, comprising forming a groove in the ends of two members so that they form a slot when positioned with the grooves adjacent one another, and inserting a connector member in the slot.
7. A frame joint substantially as hereinbefore described, with reference to and as shown in the accompanying drawings.
