Abstract
Abstract The poster display device includes a base upon which is mounted a poster frame for receiving posters and like advertising media. The means for mounting the poster frame onto the base comprise a spring structure interconnecting the lower portion of the poster frame to the base at at least two points. The poster frame normally extends vertically upwardly from the base. The surface area of the frame is relatively large. The spring structure upon which the frame is mounted permits the frame to deflect downwardly upon the application of a force thereto, as for example, the wind when the structure is located out-of-doors. The frame may deflect in either direction without danger of tipping the base. The stronger the applied force, the more the frame will deflect downwardly thus reducing the component of any force tending to topple the display device. Further, the frame size, center of gravity and base size are so dimensioned as to prevent tipping as a result of gravity leverage after the frame has been deflected by the wind.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
266 words
A display device comprising an unanchored base, said base including a pair of spaced apart elongated ground-engaging means, an upstanding frame structure having a relatively large surface area for receiving display indicia, a spring structure mounting the frame structure onto the base, said spring structure comprising spring means connected at two spaced apart locations between the lower portion of the frame structure and the base, said spring structure being mounted centrally of the groundengaging means with the plane of the frame structure at substantially right-angles to the longitudinal axis of said ground-engaging means, the surface area of the frame being of a size which normally causes displacement of the base upon application of a sufficient wind force thereagainst, said spring structure normally maintaining the frame structure in an upright position and being yieldable in either direction along an axis generally parallel to the plane of the frame structure in the direction of the longitudinal axis of the ground-engaging means, the resistance to deflection of said spring structure being such that the spring structure will deflect upon application of a force thereto less than that necessary to tip the display device and permit downward deflection of the frame structure, and where the display device is designed in accordance with the following formula: Wf (Dg - Db) < Wb Db Where: Wf is the weight of the frame structure including the spring structure. Wb is the weight of the base. Dg is the distance from the center of gravity of the sign frame structure to the bottom of the base. Db is one-half the length of the base.
Claim 2
Dependent Claim
266 words
A display device comprising an unanchored base, said base including a pair of spaced apart elongated ground-engaging means, an upstanding frame structure having a relatively large surface area for receiving display indicia, a spring structure mounting the frame structure onto the base, said spring structure comprising spring means connected at two spaced apart locations between the lower portion of the frame structure and the base, said spring structure being mounted centrally of the groundengaging means with the plane of the frame structure at substantially right-angles to the longitudinal axis of said ground-engaging means, the surface area of the frame being of a size which normally causes displacement of the base upon application of a sufficient wind force thereagainst, said spring structure normally maintaining the frame structure in an upright position and being yieldable in either direction along an axis generally parallel to the plane of the frame structure in the direction of the longitudinal axis of the ground-engaging means, the resistance to deflection of said spring structure being such that the spring structure will deflect upon application of a force thereto less than that necessary to tip the display device and permit downward deflection of the frame structure, and where the display device is designed in accordance with the following formula: Wf (Dg - Db) < Wb Db Where: Wf is the weight of the frame structure including the spring structure. Wb is the weight of the base. Dg is the distance from the center of gravity of the sign frame structure to the bottom of the base. Db is one-half the length of the base.
Claim 3

172 words
A display device comprising an unanchored base, said base including elongated ground-engaging means, an upstanding frame structure having a relatively large surface area for receiving display indicia, a spring structure mounting the frame structure onto the base, said spring structure comprising spring means connected at least at two spaced apart locations between the lower portion of the frame structure and the base, the said spring structure normally maintaining the frame structure in an upright position and being yieldable in either direction along an axis generally parallel to the plane of the frame structure to permit downward deflection thereof, and where the display device is designed in accordance with the following formula: Wf (Dg - Db) < Wb Db Where: Wf is the weight of the frame structure including the spring structure. Wb is the weight of the base. Dg is the distance from the center of gravity of the sign frame structure to the bottom of the base. Db is one-half the length of the base. Db is substantially equal to Dg.
Claim 4
Dependent Claim
172 words
A display device comprising an unanchored base, said base including elongated ground-engaging means, an upstanding frame structure having a relatively large surface area for receiving display indicia, a spring structure mounting the frame structure onto the base, said spring structure comprising spring means connected at least at two spaced apart locations between the lower portion of the frame structure and the base, the said spring structure normally maintaining the frame structure in an upright position and being yieldable in either direction along an axis generally parallel to the plane of the frame structure to permit downward deflection thereof, and where the display device is designed in accordance with the following formula: Wf (Dg - Db) < Wb Db Where: Wf is the weight of the frame structure including the spring structure. Wb is the weight of the base. Dg is the distance from the center of gravity of the sign frame structure to the bottom of the base. Db is one-half the length of the base. Db is substantially equal to Dg.
Claim 5
Dependent Claim
