Abstract

Abstract A tree stand support platform assembly including a flexible strap or band for embracing a supporting upright and front and rear band supporting legs at opposite sides of the platform movable from and to a collapsed transport position to a raised operating position. The legs are each pivotally attached to the platform and pivotally joined to one another at their respective free inner ends. There is further provided improved means for detachably retaining slidable end portions of the flexible bands at the intermediate pivot connection of the front and rear legs with the use of an axially movable knob stem threadingly engageable with a slidable slotted retainer, and inside bracket on the platform for slidably retaining one of said legs relative to the platform.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 296 words
A tree stand including a platform with a notch formed at the rear of the platform and adapted to receive an upright member; a flexible metal band adapted to embrace the upright member and having a plurality of longitudinally spaced apertures disposed inwardly of the opposed ends of the band; adjustable support means on each side of the platform including a pair of legs pivotally joined with one another at a respective intermediate end and having their respective opposite ends pivotally connected with the platform, the platform pivot connection of at least one leg of each pair of legs being alternatively movable with respect to the front and the rear of the platform, said movable pivot connection comprising a slide rail bracket anchored to said platform and defining an elongate slot, a pivot pin supported by the said one leg of said pair of legs and adapted to be slidably received by said slot; and releasable latch means for securing the pivot connection in either of said alternative positions with respect to the platform, and wherein the said elongate slot includes a relatively narrow longitudinal opening defined by substantially parallel sides, said longitudinal opening terminating at at least one end in an enlarged slot opening, said pivot pin including a groove slidably received in said longitudinal opening and an enlarged cross-sectional area adjacent said groove and configured for releasable seating engagement in the enlarged slot opening, biasing means normally urging said pivot pin in an axial direction for seating in said enlarged slot opening, and said releasable latch means including manually operable means for releasing said enlarged cross-sectional area of said pin from said enlarged slot opening against the bias of said biasing means to permit longitudinal sliding engagement of said groove in said longitudinal opening.
Claim 2
Dependent Claim 296 words
A tree stand including a platform with a notch formed at the rear of the platform and adapted to receive an upright member; a flexible metal band adapted to embrace the upright member and having a plurality of longitudinally spaced apertures disposed inwardly of the opposed ends of the band; adjustable support means on each side of the platform including a pair of legs pivotally joined with one another at a respective intermediate end and having their respective opposite ends pivotally connected with the platform, the platform pivot connection of at least one leg of each pair of legs being alternatively movable with respect to the front and the rear of the platform, said movable pivot connection comprising a slide rail bracket anchored to said platform and defining an elongate slot, a pivot pin supported by the said one leg of said pair of legs and adapted to be slidably received by said slot; and releasable latch means for securing the pivot connection in either of said alternative positions with respect to the platform, and wherein the said elongate slot includes a relatively narrow longitudinal opening defined by substantially parallel sides, said longitudinal opening terminating at at least one end in an enlarged slot opening, said pivot pin including a groove slidably received in said longitudinal opening and an enlarged cross-sectional area adjacent said groove and configured for releasable seating engagement in the enlarged slot opening, biasing means normally urging said pivot pin in an axial direction for seating in said enlarged slot opening, and said releasable latch means including manually operable means for releasing said enlarged cross-sectional area of said pin from said enlarged slot opening against the bias of said biasing means to permit longitudinal sliding engagement of said groove in said longitudinal opening.
Claim 3
Dependent Claim 58 words
The tree stand of claim 1, wherein the elongate slot terminates at opposite ends in enlarged openings for receiving the enlarged cross-sectional area of the pivot pin, and wherein the movable pivot connection and its releasable latch means secure the pivot connection at both the front and rear positions of said one leg with respect to the platform.
Claim 4
Dependent Claim 128 words
The tree stand of claim 1, wherein the pivot connection for the intermediate ends of the respective legs of said pair of legs comprises a pivot pin having a hollow bore including a threaded portion, the pivot pin of said intermediate ends simultaneously supporting both legs of said pair and a retainer for receiving and supporting said flexible band, an axially movable stem containing a threated portion for engaging the threaded portion of said bore, a protruding and portion of said stem being adapted for entry and receipt of a selected aperture of said metal band and means for moving said stem and its end portion in an axial direction for engagement with and removal from said aperture for adjustment of said band with respect to said platform.
Claim 5
Dependent Claim 64 words
The tree stand of claim 1 further including noise minimizing means comprising a block of resilient material slidably supported on one of said pair of legs and adapted for movement to a position lying between the said one leg and a juxtaposed distal end portion on the flexible metal band to prevent the band portion of the leg from noisily rubbing against one another.
