Abstract

Abstract Pedestal-type tables are joined together along two planar edges by using two pairs of alignable spaced-apart openings in the table tops. A sleeve member includes a resilient circumferential constriction closely spaced from the terminal of the sleeve wherein a fastener is used to secure the sleeve within the opening in the table top. Cylindrical connector elements each includes circumferential recesses spaced from the terminal ends to releasably receive the resilient constrictions in the sleeve member to form releasable interconnection elements in the aligned openings in the table tops when the planar edges are disposed in a juxtaposed relation.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 174 words
Apparatus to removably join together two tables comprising the combination of first and second tables each including a support secured to a top having at least one planar edge, the planar edges of the two tops having equally-spaced and alignable bored openings, a sleeve member supported in each of said openings by the table tops, the internal projected portion of each sleeve member including a resilient circumferential constriction spaced from the terminal end of the sleeve member to lie within the table top, two elongated connector elements each including two circumferential recesses spaced from the terminal ends thereof to releasably receive said resilient circumferential constrictions in the sleeve members while supported in aligned openings in the two table tops, the circumferential recesses in each connector element being spaced by a distance corresponding to the space between the circumferential constriction of two sleeve members while supported in aligned openings in the table tops when the planar edges thereof are disposed in a juxtaposed relation, and fastening means to secure each sleeve to a table top.
Claim 2
Dependent Claim 174 words
Apparatus to removably join together two tables comprising the combination of first and second tables each including a support secured to a top having at least one planar edge, the planar edges of the two tops having equally-spaced and alignable bored openings, a sleeve member supported in each of said openings by the table tops, the internal projected portion of each sleeve member including a resilient circumferential constriction spaced from the terminal end of the sleeve member to lie within the table top, two elongated connector elements each including two circumferential recesses spaced from the terminal ends thereof to releasably receive said resilient circumferential constrictions in the sleeve members while supported in aligned openings in the two table tops, the circumferential recesses in each connector element being spaced by a distance corresponding to the space between the circumferential constriction of two sleeve members while supported in aligned openings in the table tops when the planar edges thereof are disposed in a juxtaposed relation, and fastening means to secure each sleeve to a table top.
Claim 3
Dependent Claim 18 words
The apparatus according to claim 1 wherein said sleeve member is tubular and said connector elements are cylindrical.
Claim 4
Dependent Claim 35 words
The apparatus according to claim 2 wherein one end of said sleeve member includes a collar and said planar edges of the two table tops include recesses to receive the collar of each sleeve member.
Claim 5
Dependent Claim 21 words
The apparatus according to claim 2 wherein said connector elements include spherical ends between the circumferential recesses and the terminal ends.
Claim 6
Dependent Claim 27 words
The apparatus according to claim 4 wherein each sleeve member includes a spherical end wall between the circumferential constriction and the terminal end within the table top.
