Abstract
Abstract Cover members such as wall panels are releasably attached to a load-bearing member by cooperating male and female connecting means. The connecting means are secured against unintentional disengagement by a mechanical locking device which is actuatable by the connecting means during movement of the cover members relative to the load-bearing member. The force applied in moving the cover members away from the load-bearing member releases the locking device.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
280 words
In a wall panel assembly, a combination, comprising, a loadbearing member having a pair of faces extending transverse to each other and a plate-shaped cover member having an inner surface, said cover member being movable with reference to said load-bearing member to and from a predetermined position in which said inner surface extends spaced from and substantially parallel to one of said faces of said load-bearing member; a male coupling element on one of said members extending substantially parallel to said one face and a female coupling element on the other member and extending with a portion thereof substantially normal to said one face, said male coupling element being arranged to enter said portion of said female coupling element in response to movement of said movable cover member to said predetermined position; locking means on said other member for releasably holding said male coupling element in said female coupling element, said locking means being movable by said male coupling element to a locking position in response to movement of said movable cover member to said predetermined position and away from said locking position to an open position in response to movement of said movable member away from said predetermined position; and a sealing ledge fixed to one of said members and extending between said one face of said load-bearing member and said inner surface of said cover member when the latter is in said predetermined position and cooperating with said coupling elements for maintaining said inner surface of said cover member substantially parallel to said one face of said load-bearing member when said locking means in said locking position holds said male coupling element engaged in said female coupling element.
Claim 2
Dependent Claim
280 words
In a wall panel assembly, a combination, comprising, a loadbearing member having a pair of faces extending transverse to each other and a plate-shaped cover member having an inner surface, said cover member being movable with reference to said load-bearing member to and from a predetermined position in which said inner surface extends spaced from and substantially parallel to one of said faces of said load-bearing member; a male coupling element on one of said members extending substantially parallel to said one face and a female coupling element on the other member and extending with a portion thereof substantially normal to said one face, said male coupling element being arranged to enter said portion of said female coupling element in response to movement of said movable cover member to said predetermined position; locking means on said other member for releasably holding said male coupling element in said female coupling element, said locking means being movable by said male coupling element to a locking position in response to movement of said movable cover member to said predetermined position and away from said locking position to an open position in response to movement of said movable member away from said predetermined position; and a sealing ledge fixed to one of said members and extending between said one face of said load-bearing member and said inner surface of said cover member when the latter is in said predetermined position and cooperating with said coupling elements for maintaining said inner surface of said cover member substantially parallel to said one face of said load-bearing member when said locking means in said locking position holds said male coupling element engaged in said female coupling element.
Claim 3
Dependent Claim
66 words
A combination as defined in claim 1, wherein said male coupling element is a pin and said female coupling element is a bracket having two legs inclined with reference to each other, one of said legs being attached to one of said members and the other of said legs forming said portions of said female coupling element having a notch for receiving said male coupling element.
Claim 4
Dependent Claim
99 words
A combination as defined in claim 2, wherein said plate-shaped cover member has a pair of longitudinal side edges, wherein said bracket is attached to said cover member with said other leg located inwardly of one of said side edges and engaging the other face of said load-bearing member when said cover member is in said predetermined position, said sealing ledge extending fixed to said cover member along the other edge of the latter and projecting from said inner surface toward said one face of said load-bearing member, said pin projecting from said other face of said load-bearing member.
Claim 5
Dependent Claim
23 words
A coMbination as defined in claim 1, wherein said locking means comprises a hook which is pivotally attached to said female coupling element.
Claim 6
Dependent Claim
15 words
A combination as defined in claim 4, wherein said hook comprises two substantially parallel arms.
Claim 7
Dependent Claim
18 words
A combination as defined in claim 5, wherein one of said arms is shorter than the other arm.
Claim 8
Dependent Claim
43 words
A combination as defined in claim 6, comprising two detent means, one of said detent means being engageable with said locking means in said open position and the other of said detent means being engageable with said locking means in said locking position.
Claim 9
Dependent Claim
28 words
A combination as defined in claim 7, wherein movement of said locking means between open and locking positions involves a pivotal movement through an angle of about 45*.
Claim 10
Dependent Claim
24 words
A combination as defined in claim 3, wherein one of said arms extends across said notch in the locking position of said locking means.
Claim 11
Dependent Claim
31 words
A combination as defined in claim 1, wherein said female coupling element comprises means for receiving a removable blocking device arranged to prevent movement of said locking means to open position.
Claim 12
Dependent Claim
63 words
A combination as defined in claim 1, wherein said locking means comprises a pair of cam faces one of which is engaged and moved by said male coupling element during movement of said movable member to said predetermined position, and the other of which is engaged and moved by said male coupling element during movement of said movable members from said predetermined position.
