Abstract

An assembly to connect a panel to a support member. The assembly may include a saddle fitting configured to connect to the support member and including first and second plates. A back fitting may be positioned between the second plate of the saddle fitting and a second face of the panel. An index fitting includes a flange that may be positioned between the first plate of the saddle fitting and a first face of the panel, and a boss that extends outward from the flange and through the opening in the panel. The index fitting is wider than the panel and sized to fit within the gap of the saddle fitting with a first end of the index fitting contacting against the first plate and a second end of the index fitting contacting against the second plate. One or more fasteners may connect the saddle fitting to the index fitting.

First claim

What is claimed is:

1. An assembly connecting a panel to a support member, the assembly comprising:
a saddle fitting that extends from the support member, the saddle fitting comprising first and second plates that are spaced apart by a gap that receives the panel;
an index fitting configured to engage with an opening in the panel, the index fitting comprising:
a flange with an inner side and an opposing outer side, the inner side configured to contact against a first face of the panel at the opening;
a boss that extends outward from the inner side of the flange and is sized to fit within the opening in the panel, the boss comprising a face at an end away from the flange;
a back fitting with an inner side configured to contact against a second face of the panel at the opening, the back fitting further comprising an opening that aligns with the opening in the panel; and
the index fitting sized for the boss to extend through the opening in the panel and the opening in the back fitting with the inner side of the flange in contact against the first face of the panel, the index fitting further sized to fit within the gap in the saddle fitting with the outer side of the flange in contact with the first plate and the face of the boss in contact with the second plate;
wherein the saddle fitting further comprises a body that forms a channel that receives the support member, the first and second plates extending from the body, and the body further comprising one or more openings configured to receive one or more support member fasteners to attach the saddle fitting to the support member.

2. The assembly of claim 1 , wherein the boss comprises a non-circular sectional shape with a larger major axis and a smaller minor axis and with the major axis being perpendicular to the minor axis.

3. The assembly of claim 1 , wherein the face of the boss lies within a first plane and the inner side of the flange lies in a second plane with the first plane parallel to the second plane.

4. The assembly of claim 1 , wherein the flange and the back fitting are both bonded to the panel with an adhesive.

5. The assembly of claim 1 , wherein an outer side of the back fitting is spaced away from the second plate of the saddle fitting.

6. The assembly of claim 1 , wherein the flange further comprises a cut-out along an outer edge, the cut-out sized to receive a fastener to orient the index fitting relative to the opening in the panel.

7. A method of attaching the panel to the support member of the assembly of claim 1 , the method comprising:
inserting the index fitting through the opening in the panel;
positioning the outer side of the flange of the index fitting outward from the first face of the panel and the face of the boss of the index fitting positioned outward from the second face of the panel;
contacting the index fitting against the back fitting that is connected to the second face of the panel;
inserting the panel, the index fitting, and the back fitting into the gap of the saddle fitting that extends from the support member;
inserting one or more fasteners through the saddle fitting and the index fitting and connecting the panel to the saddle fitting; and
inserting the one or more support member fasteners through the one or more openings in the saddle fitting and attaching the saddle fitting to the support member.

8. The method of claim 7 , further comprising bonding the flange of the index fitting to the first face of the panel and bonding the back fitting to the second face of the panel.

9. The method of claim 7 , further comprising preventing the index fitting from rotating within the opening in the panel.

10. The method of claim 7 , further comprising positioning a top edge of the panel within the gap of the saddle fitting and positioning a bottom edge of the panel away from the saddle fitting.

11. The method of claim 7 , further comprising contacting the outer side of the flange and the face of the boss of the index fitting against the saddle fitting and spacing the saddle fitting away from the back fitting.

12. The assembly of claim 1 , wherein the boss comprises a circular sectional shape.

13. An assembly connecting a panel to a support member, the assembly comprising:
a saddle fitting configured to be connected to the support member, the saddle fitting comprising first and second plates that are spaced apart by a gap that receives the panel;
a back fitting positioned between the second plate of the saddle fitting and a second face of the panel, the back fitting shaped to extend around an opening in the panel, the back fitting further comprising an opening that aligns with the opening in the panel; and
an index fitting comprising a flange positioned between the first plate of the saddle fitting and a first face of the panel, the index fitting further comprising a boss that extends outward from the flange and through the opening in the panel and the opening, in the back fitting, the boss comprising a face positioned outward beyond the second face of the panel,
wherein the index fitting is wider than the panel and sized to fit within the gap of the saddle fitting without extending outward beyond inner surfaces of the first and second plates of the saddle fitting with an outer face of the flange of the index fitting facing away from the first face of the panel contacting against the inner surface of the first plate of the saddle fitting and the face of the boss of the index fitting contacting against the inner surface of the second plate of the saddle fitting,
wherein the saddle fitting comprises a body comprising, one or more openings to receive one or more support member fasteners to attach the saddle fitting to the support member, the first and second plates extending from the body.

14. The assembly of claim 13 , wherein the flange of the index fitting is connected to the first face of the panel with an adhesive and the back fitting is connected to the second face of the panel with the adhesive.

15. The assembly of claim 13 , wherein one or more fasteners extend through the index fitting and the saddle fitting and connect the saddle fitting to the index fitting, the fasteners comprise quick release pins with a head, an elongated shaft, and a spring loaded member that extends from the shaft.

16. The assembly of claim 13 , further comprising one or more openings that extend through the boss and the flange of the index fitting with each of the one or more openings configured to receive one of the fasteners to connect the saddle fitting to the index fitting.

17. The assembly of claim 13 , wherein the face of the boss is positioned farther outward away from the second face of the panel than an outer side of the back fitting.

18. The assembly of claim 13 , wherein the boss comprises an elongated sectional shape with a major axis that is larger than and perpendicular to a smaller minor axis.

19. The assembly of claim 13 , wherein the flange further comprises a cut-out along an outer edge, the cut-out sized to receive a fastener to orient the index fitting relative to the opening in the panel.
