Description
Background of the Invention
1. Field of the Invention
The present invention relates to connectors, and more particularly to a connector assembly for connecting adjacent panels edge to edge and to a building frame to assemble a wall or ceiling.
Summary of the Invention
A primary object of the invention is to provide a connector assembly which enables easy assembling of a wall or ceiling.
Another object of the invention is to provide a connector assembly with which a joint opening between adjacent wall or ceiling panels, when assembled, can be covered nicely regardless of dimensional errors of the individual panels and/or joint opening.
According to the present invention, a connector assembly comprises at least a pair of first members for connecting two panels edge to edge and to a building frame with a joint opening, and a second member for covering the joint opening. Each of the first members includes a base having a first portion adapted to be secured to the building frame and a second portion adapted to be held in a groove extending along an edge of a respective one of the panels. Each first member further includes retainer means formed on the first portion of the base integrally therewith and adapted to be disposed adjacent to one face of the joint opening that is to be covered. The second member has at least one leg extending into the retainer means and engageable therewith.
Many other advantages, features and additional objects of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying drawings in which preferred embodiments incorporating the principles of the present invention are shown by way of illustrative example.

Detailed Description of the Preferred Embodiments
FIG. 1 shows a part of a wall or ceiling 1 in which adjacent wall or ceiling panels 2,3 are connected edge to edge and to a building frame 4 (FIG. 2) by a connector assembly 5 with a space or joint opening between such panel edges 6,7 (FIG. 2). The panels 2,3 are made of a substantially rigid material, such as wood, particle board (or chip board), synthetic resin and the like. As shown in FIG. 2, each of the panels 2,3 has a groove 8,9 extending along one of the panel edges 6,7.
The connector assembly 5 comprises a plurality of pairs of first members 10,11 made of a rigid material such as extruded aluminum, and an elongated second member 12 made of a relatively rigid but slightly resilient synthetic resin such as polyvinyl chloride.
As shown in FIG. 2, each of the first members 10,11 includes a base having a first portion 13 fixedly received in the groove 8,9 of a respective one of the panels 2,3, and a second portion 14 secured to a portion 15 of the building frame 4 which portion extends into the joint opening from one face thereof. The second base portion 14 has a hole 16 (FIGS. 3 and 4) through which a fastening screw 17 loosely extends, the screw 17 extending threadedly into the building frame portion 15. Formed in the building frame portion 15 is a groove 18 having un-numbered threaded portions engaging the fastening screw 17. The second base portion 14 also has a projection 19 loosely extending into the groove 18. This projection 19 serves as a guide so that, when assembling, the hole 16 of the second base portion 14 can be easily and exactly aligned with the threaded portions of the groove 18 in the building frame portion 15.
Each first member 10,11 is further provided with a pair of parallel spaced arms 20,20 projecting from the second base portion 14 toward the other face of the joint opening and terminating in a pair of inwardly directed flanges 21,21, respectively. The arms 20 serve as a retainer means for the second member 12, as described below.
The second member 12 is elongate and has a generally T-shaped transverse cross section defined by a base 22 (FIG. 2) covering the joint opening on the other face and a leg 23 projecting perpendicularly from the base 22 and having on its free end a pair of lateral protruberances 24,24. The leg 23 on the second member 12 is received in a space between the opposed arms 20,20 on the first member 10,11, the protruberances 24,24 being held by or in locking engagement with the flanges 21,21 of the arms 20,20, respectively. Thus, the second member 12 is retained by the retainer means.
The base 22 of the second member 12 has a sufficient width so that the joint opening between the panels 2,3, when connected, can be covered regardless of dimensional errors of the individual panels, requiring no high degree of accuracy in attaching the first members 10,11 to the respective panels 2,3 as well as to the building frame 4.
For assembly, the first base portions 13,13 of the first members 10,11 are forced into the grooves 8,9 of the adjacent panels 2,3, respectively. Then the panels 2,3 are applied, simultaneously or one after the other, to the building frame 4 with the projection 19 loosely received in the groove 18 of the building frame portion 15 so as to have the holes 16 of the first members 10,11 aligned with the corresponding threaded portions of the groove 18. The individual first members 10,11 are then fixed at their respective first base portions 13 to the building frame 4 by the fastening screws 17. Finally, the second member 12 is forced into the joint opening from the other face thereof until the lateral protruberances 24,24 on the second member 12 are held by or come into locking engagement with the inwardly directed flanges 21,21 of the arms 20,20 on the first members 10,11. Preferably, the first members are arranged in a staggered pattern as shown in FIG. 1.
FIG. 5 illustrates a modified connector assembly 25 having a modified second member 26, with which the panels 2,3 are connected edge to edge but at a right angle to constitute a corner of the wall and/or ceiling. At such corner the building frame 4 has a pair of grooves 28,28' so that the first members 10 attached to the panel 2 are at a right angle with respect to the first members 11 attached to the panel 3, when assembled. The modified second member 26 includes a base 27 generally of L-shaped transverse cross section and a pair of parallel spaced legs 29,30 projecting one from each arm of the "L" (27) into the joint opening and terminating in a pair of inwardly projecting protruberances 31,32, respectively. The protruberances 31,32 of the legs 29,30 on the second member 26 are in locking engagement with the flanges 21 of one of the opposed arms 20 on the first member 10 and that of the first member 11, respectively.
For assembly, the panels 2,3 are attached to the building frame 4 by means of the first members 10,11, respectively, as shown in FIG. 5. Then the second member 26 is applied to the joint opening with the arms of the L-shaped base 27 parallel to the respective panel faces and moved toward the building frame 4 until the protruberances 31,32 of the legs 29,30 on the second member 26 come into locking engagement with the flange 21 of one of the opposed arms 20 on the first members 10 and the flange 21 of one of the opposed arms 20 on the first member 11, respectively.
Although various minor modifications may be suggested by those versed in the art, it should be understood that I wish to embody within the scope of the patent warranted hereon, all such embodiments as reasonably and properly come within the scope of my contribution to the art.
