Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
Suspension slide apparatus comprising in combination: an elongated track member having front and rear ends, an elongated slide member for sliding suspension mounting with said track member having front and rear ends, the said track and slide members being arranged for fully nested closure and partially nested opening and forming an elongated volume therebetween, one of said track and slide members having a latching detent mounted thereon and the other of said track and slide members having a latching key mounted thereon for engaging said latching detent to lock said track and slide members in nested closure position against inadvertent opening movement, and wherein, the latching key has a cantilever mounted resilient key end which is movable laterally in response to and in a direction perpendicular to a longitudinal actuating force while engaging said latching detent to ride over the latching detent during locking and unlocking, and the said latching detent and latching key are located essentially entirely within the said elongated volume.
Claim 2
Dependent Claim
163 words
Suspension slide apparatus comprising in combination: an elongated track member having front and rear ends, an elongated slide member for sliding suspension mounting with said track member having front and rear ends, the said track and slide members being arranged for fully nested closure and partially nested opening and forming an elongated volume therebetween, one of said track and slide members having a latching detent mounted thereon and the other of said track and slide members having a latching key mounted thereon for engaging said latching detent to lock said track and slide members in nested closure position against inadvertent opening movement, and wherein, the latching key has a cantilever mounted resilient key end which is movable laterally in response to and in a direction perpendicular to a longitudinal actuating force while engaging said latching detent to ride over the latching detent during locking and unlocking, and the said latching detent and latching key are located essentially entirely within the said elongated volume.
Claim 3
Dependent Claim
81 words
Apparatus in accordance with claim 1 wherein, the said latching key has a base portion frictionally engaged in a cutout in one of said slide and track members and said key portion is cantilever mounted from said base portion and extends between said slide and track members and parallel thereto, the other of said slide and track members having said lateral detent as a turned up end thereof extending between said slide and track members and juxtaposed to said latching key.
Claim 4
Dependent Claim
53 words
Apparatus in acCordance with claim 2 wherein, the one of said slide and track members supporting said latching key base has an end cutout laterally aligned with the latching detent in the fully nested position to allow for lateral movement of said resilient latch key end over the end of the latching detent.
Claim 5
Dependent Claim
74 words
Apparatus in accordance with claim 3 wherein, the one of said slide and track members supporting said latching key base has a recessed surface portion therein with a port in the recess accommodating said base, the base has an internally relieved construction to pass through said port for assembly and to expand against the edges of said port for frictional holding, and the base is further in laterally hooked engagement with the port edges.
Claim 6
Dependent Claim
57 words
Apparatus in accordance with claim 1 further comprising: an elongated intermediate slide/track member having front and rear ends and being nestable between said slide and track members and when so nested between said track and slide members acting as a slide with respect to said track member and as a track with respect to said slide member.
Claim 7
Dependent Claim
49 words
Apparatus in accordance with claim 6 wherein, one of said slide and track members comprises a rear end barrier and the other of said slide and track members comprises a front end barrier, the said barriers laterally overlapping respective front and end rear ends of the intermediate slide/track member.
Claim 8
Dependent Claim
73 words
Apparatus in accordance with claim 6 further comprising: a sliding storage device with at least one slidable storing element and a support structure therefor, one of the said slide and track members of the suspension slide apparatus being connected to the support structure and the other of said slide and track being connected to said slidable storage element, the suspension slide apparatus thereby forming a lockable suspension mount for said slidable storage element.
Claim 9
Dependent Claim
73 words
Apparatus in accordance with claim 1 further comprising: a sliding storage device with at least one slidable storing element and a support structure therefor, one of the said slide and track members of the suspension slide apparatus being connected to the support structure and the other of said slide and track being connected to said slidable storage element, the suspension slide apparatus thereby forming a lockable suspension mount for said slidable storage element.
