Abstract

Abstract A device for joining panels, including first and second sections which, when connected together, provide recesses for receiving the edges of the panels. Each section has two wall portions adapted to lie substantially parallel to the panels to be joined and a connection member between the wall portions. Each connection member includes two spaced limbs, the two limbs of the first section being adapted to be inserted into a recess formed between the two limbs of the second section and each limb of the first section being provided with a series of serrations engageable with a series of serrations provided on a respective one of the limbs of the second section. The limbs of the second section are substantially rigid and the limbs of the first section diverge before insertion and are resilient, so that upon insertion they are pressed together and cause their associated wall portions to be pushed into clamping contact with surfaces of the panels.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 310 words
A device for joining panels, said device comprising: a first section; a second section mounted to said first section, said first and second section mounted together to define recesses between said first and second section for receiving the edges of said panels to be joined; said first and second section each having at least two wall portions; a first connection member interposed said at least two wall portions of the first section, said first connection member having two diverging resilient limbs, each of said two limbs further being provided with a plurality of serrations; a second connection member interposed said at least two wall portions of the second section, said second connection member having two substantially rigid limbs fixed relative to each other defining a recess therebetween, each of said two limbs being provided with a plurality of serrations; and said two diverging resilient limbs of said first connection member further being adapted to be inserted into said recess defined by said two substantially rigid limbs of the second connection member and being sufficiently flexible toward each other yet rigid with their associated wall portions such that upon insertion of the two diverging resilient limbs of the first connection member into the recess defined by said two substantially rigid limbs of the second connection member; said resilient limbs are deflected toward each other and the associated wall portions of said first section are, as a result, deflected toward the other wall portions, the first and section sections are also pressed toward each other and the plurality of serrations on the two diverging resilient limbs engage the plurality of serrations on the two substantially rigid limbs to secure said first connection member to said second connection member whereby the associated first and second section wall portions are pushed into clamping contact with the respective surfaces of the panels to be joined.
Claim 2
Independent Claim 310 words
A device for joining panels, said device comprising: a first section; a second section mounted to said first section, said first and second section mounted together to define recesses between said first and second section for receiving the edges of said panels to be joined; said first and second section each having at least two wall portions; a first connection member interposed said at least two wall portions of the first section, said first connection member having two diverging resilient limbs, each of said two limbs further being provided with a plurality of serrations; a second connection member interposed said at least two wall portions of the second section, said second connection member having two substantially rigid limbs fixed relative to each other defining a recess therebetween, each of said two limbs being provided with a plurality of serrations; and said two diverging resilient limbs of said first connection member further being adapted to be inserted into said recess defined by said two substantially rigid limbs of the second connection member and being sufficiently flexible toward each other yet rigid with their associated wall portions such that upon insertion of the two diverging resilient limbs of the first connection member into the recess defined by said two substantially rigid limbs of the second connection member; said resilient limbs are deflected toward each other and the associated wall portions of said first section are, as a result, deflected toward the other wall portions, the first and section sections are also pressed toward each other and the plurality of serrations on the two diverging resilient limbs engage the plurality of serrations on the two substantially rigid limbs to secure said first connection member to said second connection member whereby the associated first and second section wall portions are pushed into clamping contact with the respective surfaces of the panels to be joined.
Claim 3
Dependent Claim 23 words
A device as claimed in claim 1, wherein the two wall portions of each section are parallel or substantially parallel to each other.
Claim 4
Dependent Claim 22 words
A device as claimed in claim 1, wherein the two wall portions of each section are at an angle to each other.
Claim 5
Dependent Claim 15 words
A device as claimed in claim 3, wherein the angle is 90° or substantially 90°.
Claim 6
Dependent Claim 52 words
A device as claimed in claim 1, wherein one of the first and second sections is elongated and wherein a plurality of the other of said first and second sections are adapted to be connected to said one elongated section in spaced relationship along the longitudinal extent of the one elongated section.
Claim 7
Dependent Claim 15 words
A device as claimed in claim 5, wherein the elongated section is the second section.
Claim 8
Dependent Claim 29 words
A device as claimed in claim 5 or 6, further comprising an elongated cover strip, each of the other sections being provided with means for supporting the cover strip.
Claim 9
Dependent Claim 35 words
A device as claimed in claim 7, wherein the support means comprises a pair of grooves formed in each of the other sections at or adjacent the edges thereof remote from the associated connection member.
Claim 10
Dependent Claim 47 words
A device as claimed in claim 8, wherein the elongated cover strip has adjacent each longitudinal edge an elongated flange engageable in a respective groove of each of the other sections and a cover portion which extends beyond the respective edge of each of the other sections.
