Abstract
Abstract A tree stand having a platform, preferably separated in a front-to-rear dimension to form a pair of side-by-side hinged platform sections for swinging movement between an operative coplanar position and an inoperative collapsed position, a pair of opposed side supporting arms pivotally mounted to the side edges of the platform and projecting upward and rearward in an operative position for straddling a tree against which the rear edge of the platform is mounted, and a cross bar connectable to the rear ends of the supporting arms behind the tree for securing the tree stand to the tree trunk in operative position. The support arms are pivotally connected to the side edge portions of the platform in such a manner that they may be swung between the operative position and an inoperative position in which the support arms are colinear with the side edges of the platform member, so that the tree stand may be folded to a compact position for transport on the back of the operator.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
249 words
A tree stand comprising: (a) a platform having a rear edge for engaging a tree trunk, a front edge, a pair of opposed straight, parallel side edge portions, and top and bottom surfaces, (b) a pair of opposed elongated support arms, each arm having a front and rear end portion and an intermediate portion, (c) a pair of struts, each strut having upper and lower ends, (d) first means pivotally connecting each of the upper ends of said struts to an intermediate portion of a corresponding support arm, (e) second means pivotally connecting each of the lower ends of said struts to a rear portion of the corresponding side edge portion of said platform, (f) pivotal mounting means for mounting the front end portions of both said support arms for swinging movement in planes normal to said platform and parallel to said side edge portions, whereby said support arms may be moved between an operative position inclined upward and rearward from said platform and extending rearward behind said rear edge, and a collapsed position in which said support arms lie substantially colinearly of said corresponding opposite side edge portions, (g) a cross bar having opposite end portions and adapted to engage a tree trunk, (h) connector means for adjustably connecting the opposite end portions of said cross bar to said pair of support arms, to position said cross bar against and behind a tree trunk straddled by said support arms and engaged by said rear edge of said platform.

A tree stand comprising: (a) a platform having a rear edge for engaging a tree trunk, a front edge, a pair of opposed straight, parallel side edge portions, and top and bottom surfaces, (b) a pair of opposed elongated support arms, each arm having a front and rear end portion and an intermediate portion, (c) a pair of struts, each strut having upper and lower ends, (d) first means pivotally connecting each of the upper ends of said struts to an intermediate portion of a corresponding support arm, (e) second means pivotally connecting each of the lower ends of said struts to a rear portion of the corresponding side edge portion of said platform, (f) pivotal mounting means for mounting the front end portions of both said support arms for swinging movement in planes normal to said platform and parallel to said side edge portions, whereby said support arms may be moved between an operative position inclined upward and rearward from said platform and extending rearward behind said rear edge, and a collapsed position in which said support arms lie substantially colinearly of said corresponding opposite side edge portions, (g) a cross bar having opposite end portions and adapted to engage a tree trunk, (h) connector means for adjustably connecting the opposite end portions of said cross bar to said pair of support arms, to position said cross bar against and behind a tree trunk straddled by said support arms and engaged by said rear edge of said platform.
Claim 3
Dependent Claim
68 words
The invention according to claim 1 in which said pivotal mounting means is operatively connected to the front end portion of each of said support arms to position said support arms in said inclined operative position in which each of said struts is in an upright position, and to position said support arms in an inoperative position in which said struts extend colinearly of said corresponding support arms.
Claim 4
Dependent Claim
77 words
The invention according to claim 2 in which said pivotal mounting means comprises a pair of pivot mounting bars each mounting bar being pivotally connected at a pivot point to a corresponding side edge portion, each of said pivot mounting bars having a free end pivotally connected to the front end portion of a corresponding support arm, whereby each of said corresponding support arms moves arcuately about said pivot point between said corresponding operative and inoperative positions.
Claim 5
Dependent Claim
25 words
The invention according to claim 2 in which each of said struts is substantially normal to the plane of said platform in said operative position.
Claim 6
Dependent Claim
32 words
The invention according to claim 2 further comprising first stop means on each of said side edge portions for limiting the downward movement of said corresponding support arm to its inoperative position.
Claim 7
Dependent Claim
30 words
The invention according to claim 4 further comprising stop means cooperating with said pivot mounting bar to limit the upward movement of said pivot mounting bar to said operative position.
Claim 8
Dependent Claim
52 words
The invention according to claim 6 in which said side edge portions comprise elongated, straight side frame bars and said stop means comprises a stop clip fixed to each of said pivot mounting bars for engagement with said corresponding side frame bar to limit the upward movement of said pivot mounting bars.
Claim 9
Dependent Claim
59 words
The invention according to claim 1 in which said platform comprises a pair of adjacent platform sections separated front-to-rear along the middle of said platform, hing means connecting said platform sections to permit said platform sections to fold from an operative coplanar position to an inoperative position in which the bottom surfaces of said platform sections oppose each other.
Claim 10
Dependent Claim
28 words
The invention according to claim 8 further comprising stop means to limit the upper movement of said adjacent portions of said platform sections to said operative coplanar position.
Claim 11
Dependent Claim
20 words
The invention according to claim 9 further comprising latch means for locking said platform sections in said operative coplanar position.
Claim 12
Dependent Claim
37 words
The invention according to claim 10 further comprising a foot strap secured to the top surface of each of said platform sections to secure the feet of a person standing on said platform in said operative postion.
Claim 13
Dependent Claim
47 words
The invention according to claim 8 further comprising harness means attached to one of said platform sections for securing said tree stand in an inoperative collapsed position, with said platform sections folded and said support arms collapsed, upon the back of a person carrying said tree stand.
Claim 14
Dependent Claim
123 words
The invention according to claim 1 in which said connector means for the opposite ends of said cross bar comprises a pair of brackets, each bracket adapted to receive the rear portion of a corresponding support arm, means journaling each of said brackets to the opposite end portion of said cross bar for swivel movement about parallel axes perpendicular to the plane of said cross bar, and means for adjustably securing each of said brackets to a rear portion of a corresponding support arm in an operative position, said bracket being adapted to be swivelled 90° so that they are axially aligned for engagement with the same support arm for securing said cross bar to said same support arm in an inoperative position.
Claim 15
Dependent Claim
63 words
The invention according to claim 1 in which said first and second pivotal connecting means and said pivot mounting means are located on the side edge portions of said platform so that the front end portions and the rear end portions of said support arms project beyond the corresponding front and rear edges of said platform substantially equally, in said inoperative collapsed position.
