Abstract
Abstract A carrying case for a portable PA system is disclosed having a panel hinged at the top and two hinged support members, one hinged near the free end of the panel and the other pivoted near the bottom of the case such that one member extends downwardly from the panel to support it near its free end and the other member extends outwardly from the case near the bottom to secure the foot end of the one member in a fixed position relative to the case. To close the case, the hinge between the two support members is swung through an arc up and into the case. As the panel is closed the end of the other member pivoted in the case is permitted to rise in the case by slots on the sides of the case for the pivots.

Claim 1
Independent Claim
206 words
In a case having a front panel, two side panels, a top panel and a bottom panel, the combination of a rear panel connected along its top edge to said case by means for permitting it to be swung up and out through an angle greater than 90* and back to a desired slanted position of less than 90* from the starting vertical position. first and second members for supporting said panel in said slanted position, said first member extending down from said panel to one end of said second member resting on a supporting surface, one end of said first member being hinged to said panel near the free end thereof and the other end of said first member being hinged to said second member at said one end thereof, the other end of said second member extending into said case, and means for pivotally attaching said other end of said second member inside said case near said bottom panel, whereby the hinge between said support members may be swung up through an arc while said rear panel swings first upwardly from said slanted position and then downwardly to a vertical position to close said case with said support members securely stowed within said case.

Dependent Claim
206 words
In a case having a front panel, two side panels, a top panel and a bottom panel, the combination of a rear panel connected along its top edge to said case by means for permitting it to be swung up and out through an angle greater than 90* and back to a desired slanted position of less than 90* from the starting vertical position. first and second members for supporting said panel in said slanted position, said first member extending down from said panel to one end of said second member resting on a supporting surface, one end of said first member being hinged to said panel near the free end thereof and the other end of said first member being hinged to said second member at said one end thereof, the other end of said second member extending into said case, and means for pivotally attaching said other end of said second member inside said case near said bottom panel, whereby the hinge between said support members may be swung up through an arc while said rear panel swings first upwardly from said slanted position and then downwardly to a vertical position to close said case with said support members securely stowed within said case.
Claim 3
Dependent Claim

The combination of claim 1 wherein said pivotal attaching means includes means for allowing the pivot of said other end of said second member to move in a plane in order to permit said other end of said second member to rise in said case as said ends of said members hinged together reach a maximum height in said case while said panel reaches said vertical position.
Claim 4
Dependent Claim
89 words
The combination of claim 1 wherein said pivoting means comprises pivots extending from sides of said second member near said other end thereof into elongated slots on said sides of said case, both of said slots having their lengths in a common plane at an angle with said bottom panel so selected as to permit said other end of said second member to rise in said case as said ends of said members hinged together reach a maximum height in said case while said panel reaches said vertical position.
Claim 5
Dependent Claim
55 words
The combination of claim 1 wherein the lengths of said first and second members are selected to secure said ends thereof hinged together in a supporting position with said first member in a substantially vertical position and said second member in a substantially horizontal position while said case is being supported by a horizontal surface.
Claim 6
Dependent Claim
67 words
The combination of claim 4 wherein said pivotal attaching means includes means for allowing the pivot of said other end of said second member to move in a plane in order to permit said other end of said second member to rise in said case as said ends of said members hinged together reach a maximum height in said case while said panel reaches said vertical position.
Claim 7
Dependent Claim
89 words
The combination of claim 4 wherein said pivoting means comprises pivots extending from sides of said second member near said other end thereof into elongated slots on said sides of said case, both of said slots having their lengths in a common plane at an angle with said bottom panel so selected as to permit said other end of said second member to rise in said case as said ends of said members hinged together reach a maximum height in said case while said panel reaches said vertical position.
Claim 8
