Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority benefit of U.S. provisional patent application No. 63/367,157 filed Jun. 28, 2022, entitled “Forms For Forming Gate Supports For Throwing Cages,” which application is incorporated herein by reference in its entirety.

FIELD OF THE DISCLOSURE

The present disclosure relates generally to throwing cages, and more particularly to forms for forming gate supports for throwing cages.

BACKGROUND

Discus/hammer throwing cages often include a pair of rotatable gates that are used primarily to confine the discus or hammer during errant throws. Right-handed throwers typically close the left-hand gate, and vice-versa for left-handed throwers, to protect against over-rotation and “pulling” the throw outside of the landing area defined by sector lines that establish the appropriate landing area for legal throws.
Typically, a rotatable gate has a wheel for support and movement of the gate, which wheel is typically supported by a hand-formed radiused concrete pad that is formed on-site during installation of the discus/hammer throwing cages. Alternatively, discus/hammer throwing cages can include a large concrete pad formed spanning the entire footprint of the throwing cage, in which case the wheels rest on the oversized pad. The rotatable gates typically feature a locking pin that can be depressed within a series of drilled holes in the concrete. The locking pin and holes secure the gates in desirable positions, and prevents the gates from moving during wind/weather events.

SUMMARY

Shortcomings of the prior art are overcome and additional advantages are provided through the provision in one embodiment for a pair of forms for constructing a first gate foundation and a second gate foundation in the support structure of a throwing cage. The pair of forms includes a first form and a second form. The first form includes an enclosure defining a cavity having an open upper end and a gate post support attached to the enclosure. The first form is installable in the support structure so that the enclosure is operable for forming a horizontal pad for supporting a wheel of a first rotatable gate of the throwing cage, and the gate post support is operable for supporting a first gate post of the first rotatable gate of the throwing cage. The second form includes an enclosure defining a cavity having an open upper end and a gate post support attached to the enclosure. The second form is installable in the support structure so that the enclosure is operable for forming a horizontal pad for supporting a wheel of a second rotatable gate of the throwing cage, and the gate post support is operable for supporting a second gate post of the second rotatable gate of the throwing cage.

The net pole sleeve assembly may have a length of about 30 inches, about 40 inches, about 48 inches, about 60 inches, and about 72 inches depending on the height of the desired net poles and net. Plastic end caps may be provided for covering the opening of the net pole sleeves when the throwing cage is not being used and removed from the support structure.
The net poles may have a length or height of about 20 feet, about 30 feet, about 40 feet, about 50 feet, about 60 feet, or other suitable length or height. The hinged stabilizer extension arms may have a length of about 36 inches.
From the present disclosure, it will be appreciated that the gate foundation forms may include supports for supporting the gate post and the net pole such as sleeves having passageways for receiving the gate post or net pole therein, sleeves or posts on which passageways in the gate post and net pole are disposed over the sleeves or posts, operably connecting members, or other suitable configurations, and combinations thereof.
The gate foundation forms may include the enclosures having the inner curved wall and the outer curved wall having a height between about 1 foot and about 3 feet, and may have a height of about 2 feet. The outer wall may be spaced between about 1 foot and 2 feet, and may be spaced 16 inches from the inner wall.
From the present description it will be appreciated that the present disclosure may provide advantages over conventional manually installed gate foundations for throwing cages. For example, the prefabricated gate foundation forms may be operable to reduce the time and effort for installation versus hand-forming a gate foundation form, which is complicated by the curvature required. The gate foundation forms may allow proper placement, elevation, and dimensions relative to the gate or wheels of the gate.
The prefabricated gate forms may provide standard dimensions preventing the horizontal pad from being too narrow or installed too shallow. The gate form pads provide a smaller footprint compared to forming a conventional large concrete pad spanning the entire footprint of the throwing cage.
The gate foundation forms may allow forming horizontal pads consistently and having even elevation, and preventing binding of the gate compared to if the horizontal pad height varies (or is installed too low in general) and does not fully support the weight of the gate, which may result in the gate binding and becoming difficult to move.
The inclusion of the gate foundation form having stops or chocks prevent the wheel of the gate from leaving the pad, which may otherwise cause the gate to bind, and may result in damage during a wind/weather event if the gates are not properly secured. The stops or chocks reduce the likelihood or prevent the gates swinging freely and banging against the remainder of the throwing cage, and reduce the stress on the gate posts when the wheels leave the curb and are no longer supporting the cantilevered weight of the gate.
The enclosure may include other configurations, for example, providing a larger horizontal pad than illustrated, providing an enclosure having one, two or three straight sides, or other configurations, but which provides after installation a portion of the pad providing a surface upon which the wheel of the gate is supported. From the present disclosure, it will be appreciated that the gates may include more than one wheel.
The enclosure, net poles, net pole sleeves, gate post sleeves, and gates may be formed from a suitable metal such as aluminum or steel.
