Abstract
Abstract A swing down closet comprises a generally box-like closet body which can be swung from an upper rest position to a lower work position while remaining generally upright, the closet being especially adapted for mounting in the entrance to a stairwell. A pair of parallel support members are mountable to the end wall of the entrance and each pivotally carries one end of a corresponding support arm, the other end of which is pivotally attached to a corresponding side of the closet body proximate the top thereof. Spring return means connected to the arm and to the end wall or the support members provide a force to return the closet body to the rest position. Automatic latch means on the support members engage the support arm at the "work" position to prevent unwanted return motion of the body. The latch means are actuated by downward movement of the closet body and released by further downward movement, after which the closet body may return to its rest position under the influence of the spring return means.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
A swing down closet comprising a closet body having top, bottom, back and side faces, a pair of rigid support members mountable to an appropriate support surface, a pair of support arms, each arm being pivotable at one end to a corresponding one of said support members and at the other end to one of said side faces proximate said top face, resilient return means connectable between each said arm and said support surface and automatic latch means on at least one of said support members for engagement with at least the corresponding arm to lock said closet body against the force of said return means, said latch means being engagable through downward movement of said closet body and releasable through further downward movement of said closet body.
Claim 2
Dependent Claim
128 words
A swing down closet comprising a closet body having top, bottom, back and side faces, a pair of rigid support members mountable to an appropriate support surface, a pair of support arms, each arm being pivotable at one end to a corresponding one of said support members and at the other end to one of said side faces proximate said top face, resilient return means connectable between each said arm and said support surface and automatic latch means on at least one of said support members for engagement with at least the corresponding arm to lock said closet body against the force of said return means, said latch means being engagable through downward movement of said closet body and releasable through further downward movement of said closet body.
Claim 3
Dependent Claim
54 words
The invention of claim 1 wherein said latch means comprises a latch plate pivotably mounted to said at least one support member so as to be gravity biased to a disengaged position, said latch plate including a camming surface and a lock portion, and first and second pin means on said corresponding support arm.
Claim 4
Dependent Claim
76 words
The invention of claim 2 wherein said first and second pin means project outwardly from said corresponding support arm whereby said first pin means is engagable with said camming surface to cam said latch plate from said disengaged position into a position for engagement of said lock portion with said second pin means, release of said second pin means from said lock portion permitting said latch plate to return, under gravity bias, to said disengaged position.
Claim 5
Dependent Claim
22 words
The invention of claim 1 and including damping means connected between at least one of said support arms and said support surface.
Claim 6
Dependent Claim
150 words
A swing down closet comprising a closet body having top, bottom, back and side faces, a pair of rigid support members mountable to an appropriate support surface, a pair of support arms, each arm being pivotable at one end to a corresponding one of said support members and at the other end to one of said side faces proximate said top face, spring means connected between each said arm and the corresponding support member, and automatic latch means comprising a latch plate pivoted to one of said support members and having a camming surface along one edge and a lock portion, said camming surface being engagable with first pin means on said arm for pivoting said plate whereby said lock portion is engagable with second pin means on said arm, further engagement of said first pin means with said camming surface disengaging said lock portion from said second pin means.
Claim 7
Dependent Claim
150 words
A swing down closet comprising a closet body having top, bottom, back and side faces, a pair of rigid support members mountable to an appropriate support surface, a pair of support arms, each arm being pivotable at one end to a corresponding one of said support members and at the other end to one of said side faces proximate said top face, spring means connected between each said arm and the corresponding support member, and automatic latch means comprising a latch plate pivoted to one of said support members and having a camming surface along one edge and a lock portion, said camming surface being engagable with first pin means on said arm for pivoting said plate whereby said lock portion is engagable with second pin means on said arm, further engagement of said first pin means with said camming surface disengaging said lock portion from said second pin means.
Claim 8
Dependent Claim
22 words
The invention of claim 5 and including damping means connected between at least one of said support arms and said support surface.
