Locking wall accessory fastener

A bracket for securing an accessory to a standard having a plurality of upwardly-projecting hook-receiving members that are located in a space between opposed ends of a pair of modular walls, said bracket comprising:

• a flat mounting plate;
• a flat hook plate made integral with the mounting plate and having at least one L-shaped hook member extending from a topmost portion of the hook plate, said L-shaped hook member detachably engaging an aperture formed between two of said hook-receiving members of said standard;
• a flat locking member having a substantially rectangular body portion with a proximate end and a distal end, the proximate end of the rectangular body portion being rotatably attached to the topmost portion on a single side of said hook plate and in close proximity to said L-shaped hook member extending therefrom;
• a protrusion integrally formed with a portion of the distal end of the rectangular body portion, an inner edge of said protrusion and a portion of said distal end of the rectangular body portion forming an abutting surface;
• said locking member having a width which is not substantially wider than a width of said hook plate such that both may fit into an aperture between a pair of hook-receiving members in the space between the opposed pair of modular walls;
• said substantially rectangular body portion having a length defined between said proximate end and said distal end which is sized whereby, when said L-shaped hook member is engaged with a particular aperture, said abutting surface may be rotated into said aperture against an L-shaped hook-receiving member immediately above said aperture, to inhibit inadvertent disengagement of said L-shaped hook member from said particular aperture.

An improved bracket for mounting to an upright accessory standard, said standard having a plurality of identical upwardly-projecting hook-receiving members that define a plurality of apertures therebetween and that are located in a space between opposed ends of a pair of modular walls, wherein the apparatus comprises:

• a flat hook plate having at least one downwardly-projecting hook member for detachable engagement with a first upwardly-projecting hook-receiving member of the accessory standard;
• and
• a flat locking member having a proximate end and a distal end, the proximate end being rotatably mounted near a topmost portion on a single side of said hook plate, said distal end having an abutting surface complementarily shaped with lower, outer edges of hook-receiving members of said accessory standard;
• said locking member having a width which is not substantially wider than a width of said hook plate such that both may fit into an aperture between a pair of hook-receiving members in the space between the opposed pair of modular walls;
• said locking member being sized and positioned whereby, when the downwardly-projecting hook member of the hook plate is detachably engaged with a first upwardly-projecting hook-receiving member of the accessory standard, the abutting surface of the locking member fits within the space between the modular walls and abuts the lower outer edge of a second upwardly-projecting hook-receiving member positioned immediately above said first hook-receiving member.
