The present disclosure relates generally to throwing cages, and more particularly to forms for forming gate supports for throwing cages.
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.
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.
In some embodiments, the first form further includes a net pole support for supporting an end of a net pole for supporting a netting of the throwing cage, and the second form further includes a net pole support for supporting an end of a net pole for supporting the netting of the throwing cage. In some embodiments, the first form includes the gate post support being a sleeve and the net pole support being a sleeve, and the second form includes the gate post support being a sleeve and the net pole support being a sleeve.
In another embodiment, a method includes, for example, installing the pair of forms in the support structure relative to a location for a throwing circle. The method may include excavating the support structure, placing the pair of forms in the excavated support structure, and placing cement in the cavities of the pair of forms. The method may further include installing a plurality of net pole supports in the support structure to support a plurality of net poles around the location for the throwing circle, and installing a throwing circle.
In another embodiment, a pair of forms for constructing a first gate foundation and a second gate foundation in a support structure of a throwing cage. The pair of forms includes a first prefabricated form and a second prefabricated form. The first prefabricated form includes an enclosure defining a cavity having an open upper end. The first form is installable in the support structure so that the enclosure is operable for forming a horizontal pad to support a wheel of a first rotatable gate of the throwing cage. The second prefabricated form includes an enclosure defining a cavity having an open upper end. The second form is installable in the support structure so that the enclosure is operable for forming a horizontal pad to support a wheel of a first rotatable gate of the throwing cage.
In another embodiment, a method includes, for example, excavating a first portion of a support structure, placing a first prefabricated form in the excavated first portion of the support structure, the first prefabricated form having an enclosure, excavating a second portion of the support structure; placing a second prefabricated form in the excavated second portion of the support structure, the second prefabricated form having an enclosure; placing uncured cement in the enclosure of the first prefabricated form with a top surface of the uncured cement even with a top edge of the enclosure of the first prefabricated form; placing uncured cement in the enclosure of the second prefabricated form with a top surface of the uncured cement even with a top edge of the enclosure of the second prefabricated form, and allowing the cement to cure.
In another embodiment, a method includes, for example, excavating a first portion of an support structure, placing a first prefabricated form in the excavated first portion of the support structure, the first prefabricated form having an enclosure connected to a gate post support, excavating a second portion of the support structure, placing a second prefabricated form in the excavated second portion of the support structure, the second prefabricated form having an enclosure connected to a gate post support, placing uncured cement in the enclosure of the first prefabricated form, placing uncured cement in the enclosure of the second prefabricated form, and allowing the cement to cure.
The subject matter which is regarded as the disclosure is particularly pointed out and distinctly claimed in the concluding portion of the specification. The disclosure, however, may best be understood by reference to the following detailed description of various embodiments and the accompanying drawings in which:
The present disclosure and certain features, advantages, and details thereof, are explained more fully below with reference to the non-limiting embodiments illustrated in the accompanying drawings. Descriptions of well-known materials, fabrication tools, processing techniques, etc., are omitted so as to not unnecessarily obscure the disclosure in detail. It should be understood, however, that the detailed description and the specific examples, while indicating embodiments of the present disclosure, are given by way of illustration only, and are not by way of limitation. Various substitutions, modifications, additions and/or arrangements within the spirit and/or scope of the underlying concepts will be apparent to those skilled in the art from this disclosure.
The present disclosure is generally directed to forming systems for throwing cages such as discus, hammer, or discus/hammer throwing cages. In particular, the present disclosure is directed to forms, such as prefabricated forms, for forming gate foundations for rotatable gates for throwing cages. As will be appreciated from the description below, the present disclosure may simplify and standardize the forming of the radiused concrete pads for the rotatable gates for throwing cages.
For example, the present disclosure as described further below is directed to a pair of prefabricated forms that allow for easy installation and support for a pair of rotatable gates for throwing cages. The forms are operable for use in a support structure such as the ground of an athletic field. The gate foundation forms may be prefabricated under manufacturing conditions thereby assuring accuracy and economy. The gate foundation forms can be readily transported, assembled, and installed to produce at the same time a pair of vertical gate post supports and a pair of horizontal pads for supporting the gate posts and the gate wheels of the throwing cages that is permanent and economical. In some embodiments, the gate foundation forms may be operable to provide a pair of a pair of horizontal pads. In some embodiments, the gate foundation forms may be operable to provide a pair of a pair of horizontal pads and a pair of vertical gate post supports. In other embodiments, the gate foundation forms may be operable to provide a pair of horizontal pads, a pair of vertical gate post supports, and a pair of vertical net pole supports. In some embodiments, the gate foundation forms may allow readily forming horizontal pads and passageways for vertical gate posts and vertical net poles in which the pads and the passageways are maintained perpendicular to each other.
For example, discus/hammer throwing cage 10 may generally include a plurality of upright net pole assemblies 100, a plurality of net pole sleeve assemblies 200, a main netting 300, a first rotating gate assembly 400, a second rotating gate assembly 500, a first gate foundation form 600, and a second gate foundation form 700. Discus/hammer throwing cage 10 may be operable for protecting spectators and others on a support structure such as a track field from an errantly thrown discus or hammer. As described in greater detail below, first and second gate foundation forms 600 and 700 are employed for use in forming a pair of arcuate pads 601 and 701 for supporting a wheel 410 of first rotating gate 400 and a wheel 510 of second rotating gate 500, respectively, on support structure 14 adjacent to throwing circle 12. In addition, as described below, first and second gate foundation forms 600 and 700 may be operable for providing support for the gate posts and the net poles. First and second gate foundation forms 600 and 700 may be mirror images of each other.
Plurality of upright net pole assemblies 100 may include spaced part elongated net poles 110 having a curved upper portion 120, and a straight lower portion 130. Plurality of net pole sleeve assemblies 200 may be disposed and installed in the support structure 14.

In other embodiments, a layout for a discus/hammer throwing cage with a single throwing circle meeting the World Athletics (formerly known as IAAF (International Association of Athletics Federation) regulations may include gate foundation forms having an enclosure having an inner wall having a radius of about 3 feet, 3¾ inches. An outer wall may be spaced a distance from the inner wall about 16 inches. In other embodiments, a layout for a discus/hammer throwing cage with a pair of throwing circles meeting the World Athletics regulations may include gate foundation forms having an enclosure having an inner wall having a radius of about 3 feet, 1 inch. An outer wall may be spaced a distance from the inner wall about 16 inches. The layouts of the throwing cages may follow the World Athletics, NCAA (National Collegiate Athletic Association), or other rules and requirements.
From the present disclosure, it will be appreciated that the gate foundations forms may be employed with discus throwing cages, hammer throwing cages, and discus and hammer throwing cages.
The throwing circle may be formed manually in the support structure or may be formed using a prefabricated throwing circle form. For example, a suitable prefabricated throwing circle may include the prefabricated throwing circle forms disclosed in U.S. Pat. Nos. 8,925,280, 8,578,678, and 8,186,684 by Oliver, which patents are incorporated herein in their entirety by reference.
The net may include a plurality of openings. For example, the net may include a plurality of generally square-shaped openings having a height and a width of about 1¾ inch to about 4 inches.
The net pole sleeve may have an outside diameter of about 4 inches and have a ⅛ inch wall. 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.
