Abstract
Abstract A connector, or so called knock down fitting, for securing together two parts of an article of furniture, such as panels P1, P2 at right angles. The connector comprises two members in which one member A has a bore 5 and the other member B has a stud 8 enterable into the bore when the two members are brought together, the bore and stud having co-operating wings 10 and shoulders 7 with angled abutment surfaces 6 whereby relative rotation between the wings and bore causes the members to be drawn and secured tightly together.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
347 words
A connector for connecting two elements together in non-parallel relation, the connector comprising two elongated body members, means at one face of each body member to engage a respective one of said elements, a generally coaxially elongated cavity in another face of one of said body members non-parallel with said firstmentioned face thereof and dimensioned non-rotatably to receive the other body member whereby said one face of the latter is exposed from the cavity, a stud having a head engageable with the bottom of the cavity to limit displacement of the stud into the cavity while permitting rotation of the stud about its axis, the stud having a T-shaped end portion within the cavity, the surfaces of the limbs of the T presented toward the head being cam surfaces oppositely angularly inclined with respect to a plane to which the axis of the stud is perpendicular, and a bore in said other body member perpendicular to said one face thereof, two shoulders integral with said other body member flanking the end portion of the bore remote from said one face of the other body member to give said end portion the form of an elongated slot, the ends of the shoulders inward of the bore comprising respective abutment surfaces generally in a common plane to which the axis of the bore is perpendicular and cam surfaces oppositely inclined with respect to said common plane to extend from circumferentially opposite ends of the respective abutment surfaces away from said one surface of said other body member, the slot being dimensioned for passage therethrough of the limbs of the stud when the latter is suitably angularly oriented and the length of the stud between its head and limbs being such in relation to the dimensions of the shoulders that rotation of the stud will cause a camming action between the limbs of the stud and the cam surfaces of the shoulders which will draw said other body member into the cavity until the limbs of the stud ride onto said abutment surfaces releasably to hold said body members together.
Claim 2
Dependent Claim
347 words
A connector for connecting two elements together in non-parallel relation, the connector comprising two elongated body members, means at one face of each body member to engage a respective one of said elements, a generally coaxially elongated cavity in another face of one of said body members non-parallel with said firstmentioned face thereof and dimensioned non-rotatably to receive the other body member whereby said one face of the latter is exposed from the cavity, a stud having a head engageable with the bottom of the cavity to limit displacement of the stud into the cavity while permitting rotation of the stud about its axis, the stud having a T-shaped end portion within the cavity, the surfaces of the limbs of the T presented toward the head being cam surfaces oppositely angularly inclined with respect to a plane to which the axis of the stud is perpendicular, and a bore in said other body member perpendicular to said one face thereof, two shoulders integral with said other body member flanking the end portion of the bore remote from said one face of the other body member to give said end portion the form of an elongated slot, the ends of the shoulders inward of the bore comprising respective abutment surfaces generally in a common plane to which the axis of the bore is perpendicular and cam surfaces oppositely inclined with respect to said common plane to extend from circumferentially opposite ends of the respective abutment surfaces away from said one surface of said other body member, the slot being dimensioned for passage therethrough of the limbs of the stud when the latter is suitably angularly oriented and the length of the stud between its head and limbs being such in relation to the dimensions of the shoulders that rotation of the stud will cause a camming action between the limbs of the stud and the cam surfaces of the shoulders which will draw said other body member into the cavity until the limbs of the stud ride onto said abutment surfaces releasably to hold said body members together.
Claim 3
Dependent Claim
88 words
A connector as claimed in claim 1, wherein the head of the stud is circular and cooperates with a circular aperture in a wall of said one body member constituting the bottom of the cavity; and lip and groove means adjacent thereto which prevents axial displacement of said stud head but permits rotation of the stud relative to said one body member and wherein the head of the stud is formed in its face exposed from said aperture with means engageable by a tool to rotate the stud.
