Abstract

Abstract A display device hooked to a signboard comprises a placard and a connecting member fixed to the signboard for hooking the placard which is provided with a L-shaped slot extending from the upper edge of the placard. The connecting member is characterized by a forwardly projecting stem adjacent one edge and an abutment member forwardly projecting from the signboard and located below the stem and further remote from the lateral edge which is adjacent the stem. The L-shape slot in the placard is adapted to engage the stem while the placard is in a tilted position and the abutment member is adapted to abut on the above-mentioned edge when the placard is pivoted in a vertical position.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 191 words
A display device comprising a placard releasably mounted on and adjacent a fixed support and a connecting member fixed on said support for allowing the hooking of said placard to said support, said connecting member including a stem forwardly projecting from said support adjacent a lateral edge thereof, an abutment member forwardly projecting from said support and located below and more remote from said lateral edge than said stem, said placard having a lateral edge, an upper edge and a generally L-shaped slot extending through said upper edge and adjacent said lateral edge of said placard, said slot having one channel extending downwardly from said upper edge and a second channel extending from said one channel to an area in the direction of the said lateral edge of the placard, the distance between said area and said lateral edge of the placard corresponding to the horizontal distance between said stem and said abutment member, whereby when said L-shaped slot is hooked on said stem at said area, said lateral edge of said placard rests against said abutment member in a substantially vertical direction and on a plane parallel to the support.
Claim 2
Dependent Claim 191 words
A display device comprising a placard releasably mounted on and adjacent a fixed support and a connecting member fixed on said support for allowing the hooking of said placard to said support, said connecting member including a stem forwardly projecting from said support adjacent a lateral edge thereof, an abutment member forwardly projecting from said support and located below and more remote from said lateral edge than said stem, said placard having a lateral edge, an upper edge and a generally L-shaped slot extending through said upper edge and adjacent said lateral edge of said placard, said slot having one channel extending downwardly from said upper edge and a second channel extending from said one channel to an area in the direction of the said lateral edge of the placard, the distance between said area and said lateral edge of the placard corresponding to the horizontal distance between said stem and said abutment member, whereby when said L-shaped slot is hooked on said stem at said area, said lateral edge of said placard rests against said abutment member in a substantially vertical direction and on a plane parallel to the support.
Claim 3
Dependent Claim 63 words
A display device as recited in claim 1, comprising a retaining plate secured to said stem and to said abutment member for maintaining said retaining plate in a substantially parallel relationship with said support at a distance slightly greater than the thickness of said placard for allowing a portion of said placard adjacent said area to slide between said plate and said support.
Claim 4
Dependent Claim 40 words
A display device as recited in claim 2, wherein said stem and said abutment member are mounted on a panel secured to said support, said panel having a lateral flange adapted to abut against said lateral edge of said signboard.
Claim 5
Dependent Claim 75 words
A display device as recited in claim 3, wherein said retaining plate comprises a brace extending in a direction substantially corresponding to a longitudinal prolongation of the direction between the stem and the abutment member, said brace having a knob projecting in a direction towards the support, said knob adapted to abut against an upper portion of the placard adjacent said one channel when said placard is hooked on said stem in a vertical position.
Claim 6
Dependent Claim 52 words
A display device as recited in claim 4, wherein said placard has a lower edge and is provided with a pair of parallel longitudinal slots extending from the lower edge of said placard and having different lengths, said longitudinal slots adapted to be engaged by a gripping rod for manipulating said placard.
Claim 7
Dependent Claim 113 words
A display device as recited in claim 5, wherein said gripping rod comprises a relatively rigid sheet having a lower flange and a tubular handle for supporting said rod, two pairs of stems projecting from said sheet in the same direction as said flange, the second pair of said stems located above said one pair, and at an angle relative to said flange, said second pair adapted to engage said longitudinal slots, a rigid strip connecting both stems of the second pair for supporting a portion of the placard between both longitudinal slots, whereby said placard is adapted to be supported by said strip and said flange and be manipulated by said handle.
Claim 8
Dependent Claim 61 words
A display device as recited in claim 6, wherein said sheet has a ridge parallel to said flange and above said two pairs of stems, said ridge protruding from the sheet on a side of the sheet corresponding to the direction of the stems, said ridge adapted to abut against said placard when the latter is manipulated by said gripping rod.
