Abstract

A pedestal assembly for an EAS system comprises an antenna, an electronic assembly, and a support member having at least first and second recesses. The antenna is seated in the first recess and the electronic assembly is seated in the second recess. Bumpers are secured to opposed sides of the support member and a top cap member is applied to the assembled support member and bumpers. Upper ends of front and rear covers are inserted interiorly of the top cap member and thereby retentively circumscribed. Lower ends of the first and second covers are then secured to the support member to complete the pedestal assembly. Field service is facilitated in that all interior components of the pedestal assembly are accessible simply upon unsecuring the lower ends of the covers from the support member and downwardly sliding the covers from the top cap member. The support member comprises a two-layer plastic body, one layer of which defines the first and second recesses. The two-layer plastic body is preferably a thermoformed molded body.

Claims

1. An upstanding pedestal assembly for an electronic article surveillance system, comprising:

(a) an antenna;

(b) an electronic assembly;

(c) a support member having first and second recesses, said antenna being seated in said first recess, said electronic assembly being seated in said second recess;

(d) first and second bumpers secured to sides of said support member;

(e) a top cap member secured to said support member; and

(f) first and second covers secured to said support member to jointly enclose front and rear sides of said support member;

upper ends of said first and second covers being circumscribed by said top cap member and said bumpers abutting said covers and applying transverse compressive force thereto.

2. The pedestal assembly claimed in claim 1, wherein said support member further defines first sockets, first securement members extending through said electronic assembly and being retentively disposed in said first sockets.

3. The pedestal assembly claimed in claim 2, wherein securement members are quick release fasteners.

4. The pedestal assembly claimed in claim 1, further including a fan having an exhaust port adjacent said electronic assembly, said support member further defining an inlet air duct in communication with an inlet of said fan for conducting air ambient to said pedestal assembly to said fan.

5. The pedestal assembly claimed in claim 4, wherein said support member further defines an outlet air duct at an upper end thereof issuing air into said top cap member.

6. The pedestal assembly claimed in claim 5, wherein said first and second covers define exhaust openings communicating with said top cap member interior and wherein air issuing into said top cap member is deflected downwardly to issue to ambient environment through said first and second cover exhaust openings.

7. The pedestal assembly claimed in claim 1, wherein said top cap member includes a lens structure.

8. The pedestal assembly claimed in claim 1, wherein said support member further defines conduit means for receiving electrical cables for providing electrical communication with said electronic assembly and said antenna.

9. The pedestal assembly claimed in claim 8, further including a template secured to a lower end of said support member and defining a passage therethrough in registry with said conduit means permitting feeding of said electrical cables into said conduit means.

10. The pedestal assembly claimed in claim 1, wherein said first and second covers each define first and second apertures at said lower ends thereof, the assembly further including first and second securement members extending through said first and second apertures and retentively disposed in first and second sockets formed in said support member.

11. The pedestal assembly claimed in claim 10, wherein said first and second securement members are quick release fasteners.

12. The pedestal assembly claimed in claim 1, wherein said support member comprises a two-layer plastic body, one layer of which defines said first and second recesses.

13. The pedestal assembly claimed in claim 12, wherein said two-layer plastic body is a thermoformed molded body.

14. The pedestal assembly claimed in claim 1, wherein said antenna comprises first and second coils and wherein said first recess includes first and second grooves for respective seating of said first and second coils.

15. A method for assembling an EAS pedestal, comprising the steps of:

(a) preforming a support member with first and second recesses of configurations respectively to receive an electronic assembly for said EAS pedestal and at least one antenna;

(b) inserting said electronic assembly and said at least one antenna into said first and second recesses;

(c) securing first and second bumpers to opposed sides of said support member;

(d) securing a top cap member to said support member to form a preassembly;

(e) forming first and second covers of configuration to jointly enclose front and rear sides of said preassembly;

(f) inserting upper ends of said first and second covers interiorly of said top cap member; and

(g) securing lower ends of said first and second covers to said support member in facing relation to front and rear sides of said preassembly.

16. The method claimed in claim 15, wherein said support member is further formed with sideward projections and said bumpers formed with channels for receiving said projections and

said step of securing first and second bumpers to opposed sides of said support member is practiced by inserting said projections in said channels.

17. The method claimed in claim 15, wherein said top cap member is selected to be of configuration for retentively circumscribing upper ends of said first and second covers and upper ends of said bumpers.

18. The method claimed in claim 15, wherein said step of securing lower ends of said first and second covers to said support member in facing relation to front and rear sides of said preassembly is practiced by use of quick release fasteners.
