Abstract
Abstract An attachment assembly for releasably joining panels or partitions along their edges is disclosed which comprises two channel members each being secured along the edge portions of the panels to be joined. Separable fastening members are secured in each channel member in a manner permitting the fastening members to slide along each channel member. The panels or partitions are secured together by engagement of the fastening members on each channel member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
214 words
An attachment assembly for releasably joining two panels together along a joint defined by abutting edge portions of the panels comprising: a. first and second relatively rigid channel members secured to the respective edge portions of said panels; b. first and second flexible backing members slidably mounted within the respective channel members for selective removal therefrom; c. first and second complementary piles of releasably interengageable hooking elements disposed on the facing surfaces of the respective backing members, the hooking elements of said piles being characterized by the property that with the two piles in interengaged condition forming the joint separation of the panels is strongly resisted by forces to which the joint is normally subjected applied generally parallel or perpendicular to the interfacial plane of engagement between the piles, but quite readily effected by peeling the flexible backing members apart, each of said channel members being suf-ficiently rigid to prevent the application of peeling forces to the backing members when the piles are in interengaged condition; and d. retaining means for holding the backing members in slidably removable condition within the respective channel members in such a manner as to prevent each backing member from being otherwise removed from the respective channel member by forces to which the joint is normally subjected during use.

Claim 3
Dependent Claim
74 words
The attachment assembly according to claim 1 wherein: a. each backing member is sufficiently stiff to prevent it from being bent out of its retained position within the respective channel by forces to which the joint is normally subjected during use; and b. said retaining means includes a pair of oppositely disposed flanges carried by each of said channel members for engaging the opposite margins of said facing surface of the respective backing member.
Claim 4
Dependent Claim
17 words
An attachment assembly according to claim 2 wherein said channel members and backing members are continuous strips.
Claim 5
Dependent Claim
28 words
An attachment assembly according to claim 2 wherein the backing members each include a plurality of individual sections placed in end to end relationship along said channel members.
Claim 6
Dependent Claim
32 words
An attachment assembly according to claim 4 wherein the ends of said backing member sections in one channel member overlap the ends of said backing member sections in the other channel member.
Claim 7
Dependent Claim
29 words
An attachment assembly according to claim 2 wherein grooves are provided along the end portions of said channel members to facilitate removal of said backing members from said channels.
