Abstract

An electrical junction block housing is mounted on a structural member in a raceway by means of spaced-apart L-shaped mounting brackets and a retaining tab integral to a support plate. The housing is provided with L-shaped attachment lugs for slidably engaging the support brackets. A latching device engaging the retaining tab is used to maintain the housing in position relative to the support bracket. The latching device includes a pair of opposing interlocking members hingedly attached to the housing allowing the housing to be inserted and removed from either side of the structural member. The opposing interlocking members, which define a channel between them for engaging the retaining tab, include a cooperating tongue on one of the interlocking members and groove on the other of the interlocking members. A force exerted on either of the interlocking members in the direction of the housing causes both interlocking members to move in the direction of the housing, thereby disengaging both members from the retaining tab and allowing the junction block housing to be removed in the direction of the interlocking member on which the force was exerted. The interlocking members are made of a resilient plastic material, providing a returning force on the hinged members in the direction of the retaining tab.

Claims

1. A mounting arrangement for mounting a housing having an outer wall on a structural support member, said arrangement comprising:

first and second spaced-apart support brackets on said structural support member;

first and second spaced-apart attachment lugs on said outer wall of said housing for slidably engaging said first and said second support brackets, respectively;

retaining means on said supporting member;

latch means comprising a pair of opposing interlocking movable latch members hingedly attached to said outer wall of said housing and defining therebetween a channel for engaging said retaining means; and

each of said interlocking latch members is operable to disengage both of said latch members from said retaining means in response to an external force on either of said latch members, whereby said retaining means is disengaged from said latch means by operation of either of said latch members to allow sliding movement of said housing in opposite directions on said support brackets.

2. The arrangement in accordance with claim 1 wherein said channel defined by said interlocking members extends in a direction parallel to a longitudinal axis of said housing and transverse to the direction of sliding engagement of said attachment lugs with said support brackets and wherein one of said interlocking members comprises an extension member extending across said channel for engagement with the other of said interlocking members, whereby movement of one of said interlocking members toward said outer wall causes movement of both of said interlocking members toward said outer wall and disengagement of both of said interlocking members from said retaining means.

3. The arrangement in accordance with claim 2 wherein said housing comprises an electrical junction block for interconnecting electrical wiring and supporting an electrical outlet.

4. The arrangement in accordance with claim 3 wherein said junction block is mounted within a raceway of a wall panel.

5. The arrangement in accordance with claim 1 wherein said latch members each comprise an attachment member attached to said outer wall and an angular member extending at an acute angle relative to said attachment member and hingedly attached to said attachment member.

6. The arrangement in accordance with claim 5 wherein said outer wall comprises an exterior and interior surface, wherein said angular members are disposed above the exterior surface, and wherein said attachment members are attached to said interior surface.

7. The arrangement in accordance with claim 6 wherein said outer wall is provided with first and second detents and wherein said angular members are attached to corresponding attachment members by means of an interconnecting sections disposed within said detents.

8. The arrangement in accordance with claim 1, further comprising a support plate attached to said structural member and wherein said support brackets and said retaining means form an integral part of said support plate.

9. An electrical junction block housing adapted for attachment to a support structure, comprising an outer wall and a pair of spaced-apart, substantially L-shaped attachment lugs extending outwardly from said outer wall for slidably engaging corresponding support brackets;

latch means disposed between said attachment lugs and comprising a pair of opposing interlocking movable latch members defining therebetween a channel for engagement with a retaining member, said latch members hingedly attached to said outer wall and movable with respect to said outer wall, wherein movement of one of said latch members toward said outer wall causes movement of both of said latch members toward said outer wall for disengaging said defined channel from a retaining member.

10. The housing in accordance with claim 9 wherein one of said latch members comprises an elongated member extending across said channel and the other of said latch members comprises an opening for engaging said extension member, wherein said extension member and said opening cooperate to cause movement of both of said latch members in the direction of said housing when one of said interlocking members is moved in the direction of said housing.

11. The housing in accordance with claim 10 and further comprising a pair of attachment members hingedly connected to corresponding ones of said latch members and attached to said outer wall.

12. The arrangement in accordance with claim 11 wherein said outer wall comprises exterior and interior surfaces, wherein said latch members are disposed outside said exterior surface and said attachment members are attached to said interior surface and hingedly attached to said interlocking members by means of interconnection sections and wherein said wall is provided with a pair of detents and said interconnecting sections are disposed within said detents.

13. The housing in accordance with claim 9 wherein said latch members are constructed of a material having resilient properties providing a restoring force to said latch members away from said outer wall.

14. The housing in accordance with claim 9 wherein said outer wall comprises opposite exterior edges extending in a direction substantially parallel to said channel and one of said latch members is attached to said outer wall near each of said edges.

15. The housing in accordance with claim 9 wherein said interlocking latch members are formed integral with said outer wall.
