Abstract
Abstract A mounting bracket system mounts a factory data collection terminal vertically to a wall to secure the terminal rigidly to the wall surface and also to permit a quick disconnect of the terminal. This is accomplished by fastening two brackets with keyhole slots which are attached to the upper area of the terminal and using two spring loaded captive fasteners which are accessible from the front of the terminal and attached to the bottom of the terminal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A factory data collection terminal including a quick disconnect wall bracket for mounting said terminal on a vertical surface without removing a cover from said terminal, said terminal comprising: terminal backplate means fastened to said terminal including a plurality of brackets with keyhold slots; and wall bracket means fastened to said vertical surface having support means for supporting the weight of said terminal and preventing said terminal from vibrating; said terminal backplate means including captive screw means threadably engaging said wall bracket means for securely fastening said terminal backplate means to said wall bracket means and providing an indication when said terminal backplate means is free of said wall bracket means; both said terminal backplate and wall bracket means extending below said terminal.
Claim 2
Dependent Claim
123 words
A factory data collection terminal including a quick disconnect wall bracket for mounting said terminal on a vertical surface without removing a cover from said terminal, said terminal comprising: terminal backplate means fastened to said terminal including a plurality of brackets with keyhold slots; and wall bracket means fastened to said vertical surface having support means for supporting the weight of said terminal and preventing said terminal from vibrating; said terminal backplate means including captive screw means threadably engaging said wall bracket means for securely fastening said terminal backplate means to said wall bracket means and providing an indication when said terminal backplate means is free of said wall bracket means; both said terminal backplate and wall bracket means extending below said terminal.
Claim 3
Dependent Claim
39 words
The terminal of claim 1 wherein said terminal backplate means comprises: a flat plate fastened to said terminal and including a plurality of tapped holes; said plurality of brackets fastened to said flat plate; and said captive screw means.
Claim 4
Dependent Claim
116 words
The terminal of claim 2 wherein said captive screw means comprises: a plurality of coil springs; a plurality of captive screws, each having a head portion, an unthreaded portion and a threaded portion; and a plurality of collars, each having a tapped hole and permanently fastened to said flat plate so as to have said tapped hole aligned with each of a plurality of holes; said captive screw means being assembled by placing said coil spring over said unthreaded portion so that said coil spring remains compressed between said head portion and said collar when said captive screw is screwed completely through said tapped hole so that said unthreaded portion fits loosely in said tapped hole.
Claim 5
Dependent Claim
37 words
The terminal of claim 3 wherein said wall bracket means comprises: a wall bracket for fastening to said vertical surface and having a plurality of tapped holes for receiving said captive screw means; and said support means.
Claim 6
Dependent Claim
144 words
The terminal of claim 4 wherein said support means comprises: a plurality of threaded studs, each fastened to said wall bracket; a nut threaded onto each of said studs; a lock washer placed over each of said studs; a washer placed over each of said studs; and a stop fastened to the end of each of said studs; said terminal being assembled to said wall bracket means wherein each of said stops are passed through a large diameter of each of said keyhole slots and said terminal positioned relative to a small diameter of each of said keyhole slots so that the said terminal is prevented from vibrating when said nuts are tightened to force each of said plurality of brackets between respective ones of said washers and said stops, each of said lock washers preventing the respective one of said nuts from loosening.
Claim 7
Dependent Claim
75 words
The terminal of claim 5 wherein each of said plurality of captive screws are screwed into respective ones of said tapped holes of said wall bracket, thereby compressing each of said plurality of coil springs between said head portions and said collar, each of said plurality of captive screws "popping out" when removing said terminal from said vertical wall indicating that each of said plurality of captive screws is disengaged from said wall bracket means.
