Abstract

A frame apparatus for mounting a display panel of the type having frame members and frame connectors, the latter with fasteners. Each frame member includes a plurality of outwardly-extending arm structures and a grooved fastener-bearing surface between each adjacent pair of arm structures. The connector bears against the underside of coplanar opposed strips extending at the ends of an adjacent pair of arm structures. The connector has wing-like compression members facilitating the connection of adjoining frame members. Such connectors are configured to allow multiple joint forms and butt joints at any angle.

Claims

1. In an apparatus for mounting a display panel and including a frame member and a frame connector having a fastener, the frame member having (a) a plurality of arm structures extending outwardly from a frame axis, and (b) a fastener bearing surface between a pair of arm structures, the improvement wherein:

the connector comprises a center portion and a pair of wing-like compression members extending from the center portion at an angle of greater than 90° and

less than 180°

; and

the fastener bearing surface includes a pair of spaced elongate rails between the pair of arm structures,

whereby the fastener bears against the rails and urges the connector against the pair of arm structures.

2. The apparatus of claim 1 wherein:

the pair of arm structures defines an angle therebetween; and

a plane coincident with the rails is substantially perpendicular to a line bisecting the angle.

3. The apparatus of claim 2 wherein each elongate rail has a substantially flat surface and the flat surfaces are coplanar.

4. The apparatus of claim 1 wherein each of the pair of arm structures has:

a distal edge; and

a strip extending along the distal edge; and

wherein;

the rails have a groove therebetween;

the strips have a gap therebetween; and

the groove is in registry with the gap.

5. The apparatus of claim 4 wherein:

the pair of arm structures define an angle therebetween; and

a plane bisecting the angle also bisects the gap and the groove.

6. The apparatus of claim 4 wherein the gap and the groove each have a width and the width of the gap is substantially greater than the width of the groove.

7. The apparatus of claim 1 wherein:

the frame member has four arm structures; and

each pair of arm structures has a pair of rails therebetween.

8. The apparatus of claim 7 wherein at least one of the pair of rails between a pair of arm structures has a substantially flat surface.

9. The apparatus of claim 1 including a colored channel member engaging at least one arm structure.

10. The apparatus of claim 9 wherein the channel member includes a slot for receiving a display panel.

11. In an apparatus for mounting a display panel and including a frame member and a frame connector, the frame member having a plurality of arm structures extending outwardly from a frame axis, and wherein each arm structure has a strip, the improvement wherein:

the connector comprises a center portion and a pair of wing-like compression members extending from the center portion at an angle greater than 90° and

less than 180°

; and

each of the pair of compression members bears against a strip of each of two arm structures.

12. The apparatus of claim 11 wherein:

at least one arm structure and a strip define a V-channel;

at least one compression member has an edge; and

the compression member edge substantially fits into the V-channel.

13. The apparatus of claim 11 wherein at least one compression member includes a notch formed therein.

14. The apparatus of claim 13 wherein:

each compression member includes a pair of laterally disposed notches formed therein;

the apparatus has a pair of abutting frame members angular to one another; and

a strip of a separate arm structure is received in each notch.

15. The apparatus of claim 14 wherein:

each connector includes a long axis;

each compression member has an end;

the ends are angled with respect to the long axis of the connector; and

each compression member end bears against a separate adjacent arm structure.

16. The apparatus of claim 11 wherein each of the wing-like compression members is at about a 135°

angle to the connector center portion.

17. The apparatus of claim 11 wherein the connector center portion has a narrow substantially flat central region devoid of compression members.

18. The apparatus of claim 11 including a colored channel member engaging at least one arm structure.

19. In a frame apparatus for mounting a display panel having an outside and including a frame member and a frame connector, the frame member having a plurality of arm structures extending outwardly from a frame axis and forming a space therebetween, the improvement wherein:

the frame member has a center structure adjacent to the space and from which the arm structures extend;

the connector is bent to form an angle of about 90° and

has two portions, one portion on each side of such bend, at least one of the portions having an elongate aperture therethrough;

a bolt extending through the center structure and the elongate aperture and having a turn-engageable end exposed to the outside of the frame apparatus, and having on its threaded portion;

a trapped threaded member rotationally restrained within the space between the arm structures; and

a fixed member at an end opposite the turn-engageable end of the bolt, the threaded length of the bolt between the fixed member and the turn-engageable end being more than the combined dimensions of the frame member center structure and the thickness of the connector;

whereby bolt turning loosens and tightens the attachment of the frame member and the connector;

thereby allowing sliding expansion of the frame apparatus to facilitate display panel replacement.

20. The apparatus of claim 19 wherein the channel member includes a slot for receiving a display panel.

21. In an apparatus for mounting a display panel and including a frame member and a frame connector having a fastener, the frame member having (a) a plurality of arm structures extending outwardly from a frame axis, and (b) a fastener bearing surface between a pair of arm structures, the improvement wherein:

the fastener bearing surface includes a pair of spaced elongate rails between the pair of arm structures;

each of the pair of arm structures has a distal edge and a strip extending along the distal edge;

and wherein;

the rails have a groove therebetween;

the strips have a gap therebetween;

the groove is in registry with the gap;

the gap and the groove each have a width; and

the width of the gap is substantially greater than the width of the groove,

whereby the fastener bears against the rails and urges the connector against the pair of arm structures.

22. In an apparatus for mounting a display panel and including a frame member and a frame connector, the frame member having a plurality of arm structures extending outwardly from a frame axis, and wherein each arm structure has a strip, the improvement wherein:

the connector comprises a center portion and a pair of wing-like compression members extending angularly from the center portion;

each of the pair of compression members bears against a strip of each of two arm structures;

each compression member includes a pair of laterally disposed notches formed therein;

the apparatus has a pair of abutting frame members angular to one another; and

a strip of a separate arm structure is received in each notch.

23. The apparatus of claim 22 wherein:

each connector includes a long axis;

each compression member has an end;

the ends are angled with respect to the long axis of the connector; and

each compression member end bears against a separate adjacent arm structure.
