Platform assembly
A platform assembly adapted for securement to a support. The platform assembly includes a base having a front end and a rear end, and a brace adapted to be secured to the support. The rear end of the base is pivotally secured to the brace. At least one flexible strap supports the front end of the base at a selective angle relative to the base.
The present invention relates generally to a platform assembly for securement to a support.
Platform assemblies that are capable of being secured to a support (e.g., a tree, boat, building) have a wide variety of uses and applications. For example, a platform assembly that is secured to a tree (often called a tree stand) can be used to support hunters elevated above game. As another example, a platform assembly that is secured to the exterior of a hull of a boat can be used to support a hunting dog used to retrieve killed game from the water. The platform assembly allows the dog to spot the killed game that is in the water and allows to dog to have easy and quick access to the water.
A typical platform assembly comprises a brace that is secured to a support and a base that extends outward from the brace. Typically, the angle of the base with respect to the brace is fixed at 90 degrees. This configuration may be adequate or even desirable in many situations, however sometimes it may be more desirable to have the base extend at an angle less than or greater than 90 degrees. For example, if the support (e.g., a tree) is slanted, and the user wants the base to extend horizontally (i.e., parallel with horizon), then the user must be able to adjust the angle of the base with respect to the brace to properly configure the platform. One such platform assembly allowing the user to adjust the angle of the base is a tree stand disclosed in my U.S. Pat. No. 5,995,475, the entirety of which is herein incorporated by reference. This tree stand includes rigid metal arms adjustable in length for supporting a base of the stand. Varying the length of the arms changes the angle of the base with respect to the brace.
In another exemplary prior art platform, metal chains support the front end of the base. Typically, the metal chains are secured to the brace using pins that are received through selected links of the chain and detachably secured the brace. To adjust the angle of the brace with respect to the base, the user must remove the pins from the brace thereby detaching the chains from the brace, adjust the lengths of the chains extending between the brace and the base, and then, when the desired angle is reached insert the pins through the corresponding links and into the brace. Detaching the chain from the brace is not desirable. There is also a possibility that the pin (or other device(s) securing the chains to the brace) may inadvertently become disconnected from the brace while the platform is in use.
SUMMARY OF INVENTIONIn general, the present invention relates to a platform assembly adapted for securement to a support. The platform assembly comprises a base having a front end and a rear end, and a brace adapted to be secured to the support. The rear end of the base is pivotally secured to the brace. At least one flexible strap supports the front end of the brace at a selected angle relative to the base.
In another aspect, the present invention relates to a tree stand for securement to a tree. The tree stand comprises a base having a front end and a rear end, and a brace. The base is sized and shaped for supporting an adult human in a standing position on the base. The rear end of the base is pivotally secured to the brace. A securement device having opposite ends adapted for connection to the brace is adapted to pass around the trunk of the tree to secure the brace to the tree. At least one flexible strap supports the front end of the base. The flexible strap is adjustable in length for selectively adjusting an angle of the base with respect to the brace for use in leveling the base.
In yet another aspect, the present invention relates to a platform assembly adapted for securement to a support. The platform assembly comprises a base having a front end and a rear end, and a brace adapted to be secured to the support. The rear end of the base is pivotally secured to the brace. At least one flexible member is attached to the base and the brace for supporting the front end of the base. The platform assembly also comprises an adjustment device for adjusting a length of the flexible member without detaching the flexible member from either the base or the brace.
Other objects and features will be in part apparent and in part pointed out hereinafter.

DETAILED DESCRIPTION OF THE DRAWINGS Referring now to the drawings and in particular to
The base 15 of the illustrated embodiment comprises a frame 26 having a pair of laterally spaced elongate side members 28A, 28B and a front cross member 30 (
The brace 17 of the illustrated embodiment is pivotally secured to the base 15 at a lower end and projects up from the base (

Referring to
In the illustrated embodiment (
Because of frictional forces produced by sliding movement of the intermediate portion 55 of the strap 24 on the engagement bar 44 and the forces exerted on the bar by the strap to support the base 15, the intermediate portion of the strap is preferably reinforced so that it is stronger and more durable than other portions of the strap. For example (

As shown in
It is understood that in the embodiment where the strap 22 is selectively adjustable, the adjustable strap, in its broadest sense, is an adjustable flexible member and the buckle 60, in its broadest sense, is an adjustment device. It is contemplated that in other embodiments (not shown) the adjustable flexible member can be a cable or a chain, for example, or other flexible member without departing from the scope of this invention. Accordingly, it is also contemplated that the adjustment device can be a cable grip or a chain-hoist, for example, or any other device that is suitable for selectively adjusting the length of the adjustable flexible member without having to detach the adjustable flexible member from either the brace or the base.
In the illustrated embodiment (
As shown best in
The tree stand 10 of the illustrated embodiment also comprises a safety belt 123 having opposite ends secured to the brace 17, at least one of which is detachably secured to the brace. The belt 123 engages and extends around the tree T. The safety belt 123 has a buckle 124 for adjusting the length of the belt to accommodate differing diameters of trees. The safety belt 123 is a back-up device in case the chain 115, which is the primary securement device securing the stand to the tree, fails.
