Abstract
Abstract This invention provides a support device for a mirror or like flat member in which upper and lower horizontal edges of the flat member are engaged by hook portions carried by upper and lower cross pieces mounted on a common vertical support rod by which the device is suspended. The upper cross piece is spring urged downwardly to enable the device to grip flat members of different heights.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
Device for supporting mirrors, plates, panels and like flat members, comprising in combination: - a. a vertical cylindrical support member having suspension means at its upper end; - b. a lower tubular cross piece secured to the lower end of said support member, said lower cross piece having a rectangular cross section; - c. two upwardly projecting hook portions carried at the ends of said lower cross piece; - d. an upper tubular cross piece of rectangular cross section mounted slidably and rotatably on the upper part of said support member; - e. two downwardly projecting hook portions carried at the ends of said upper cross piece, and - f. a spring mounted on the support member and attached to the upper tubular cross piece to pull the latter downwardly towards thE lower cross piece, said hook portions being adapted to engage respective upper and lower horizontal edges of a said flat member to grip the latter by virtue of the force exerted on the upper cross piece by said spring.
Claim 2
Dependent Claim
171 words
Device for supporting mirrors, plates, panels and like flat members, comprising in combination: - a. a vertical cylindrical support member having suspension means at its upper end; - b. a lower tubular cross piece secured to the lower end of said support member, said lower cross piece having a rectangular cross section; - c. two upwardly projecting hook portions carried at the ends of said lower cross piece; - d. an upper tubular cross piece of rectangular cross section mounted slidably and rotatably on the upper part of said support member; - e. two downwardly projecting hook portions carried at the ends of said upper cross piece, and - f. a spring mounted on the support member and attached to the upper tubular cross piece to pull the latter downwardly towards thE lower cross piece, said hook portions being adapted to engage respective upper and lower horizontal edges of a said flat member to grip the latter by virtue of the force exerted on the upper cross piece by said spring.
Claim 3
Dependent Claim
29 words
Device as claimed in claim 1, wherein the spring is a helical tension spring coaxially surrounding the support member and anchored at its lower end to said support member.
Claim 4
Dependent Claim
28 words
Device as claimed in claim 2 wherein the support member is provided with a number of perforations in which the lower end of the spring is selectively engageable.
Claim 5
Dependent Claim
26 words
Device as claimed in claim 1, wherein the hook portions are formed by respective stirrup elements secured to the ends of the respective tubular cross pieces.
Claim 6
Dependent Claim
