COMPONENT FRAME OF A PITCHING SCREEN
A pitching screen frame formed from a generally planar rigid member separably interconnected with other structural members at joints formed in the rigid member. The planar rigid member can include a welded triangle. The welded triangle can be integrally formed into a vertical member including a T at a bottom portion, and interfitting points at a top and one or more ends for coupling with other tubes in order to construct a frame of a pitching screen as shown in the various drawings. The joints between the planar rigid member and other pitching screen components can be made by bolting, clipping, swaging, pinning, gluing, and so on. A variety of sets of components can be provided to produce a pitching screen frame. The figures depict example implementations of the disclosed subject matter. Other implementations would be understood in view of these examples.
This application claims priority from U.S. Provisional Application Ser. No. 61/581,385, titled “Pitching Screen”, and filed on Dec. 29, 2011, the entire contents of which is incorporated herein by reference in its entirety.
BACKGROUNDA pitching screen is often generally in an L shape (viewed from a position of a batter), such that a thrower maintains a body position behind a tall part of the screen, and throws around an edge of the screen. The terms pitching screen and L-screen generally are used interchangeably herein, unless otherwise evident from context.
An L-screen can be build from pieces of steel tubing fully welded together. The fully welded frames are considered high end and are expensive. Welded frames are typically constructed from heavy duty pipe or round tubing made of steel or aluminum.
L-screen kits exist that come as sections of tubing that are bolted or snapped together. Most bolt together frames are made of steel; and use traditional bolts or snap together frames for easy customer assembly.
SUMMARYA welded frame for a pitching screen is costly to ship, since it is typically around 6.5-8.5′ in height and width, and must ship via LTL/Freight because traditional residential carriers are not capable of handling or are unwilling to handle a package that large. Bolt together frames suffer from inadequate long-term lateral and horizontal rigidity. One reason for loss of lateral and horizontal rigidity is the comparatively flexible nature of a bolt together joint, as well as wear of the holes that allow the bolt, pin or snap to pass through the pipes. Increasing rigidity comes at a cost of increasing a strength of pipe used and/or hardware used to secure the pipes together. The relative movement of the pipes with respect to each other in a bolt together screen eventually wears on the bolt, through holes, and other components assembled components, such that these joints allow the frame to fail; leading to rapid replacement.
In one aspect, the disclosure presents a pitching screen with a welded vertical member that presents a rigid planar section in the plane of the screen. In one particular example, the welded vertical member includes a fully welded triangle portion generally in a middle portion of the pitching screen. The fully-welded triangle portion reduces twisting and bending of the frame in the center, in contrast to a bolt together screen. The vertical member can have a T-shaped section and a receiver portion distal the T-shaped intersection. Each end of the T-shaped section can interfit with tubing that defines a remainder of the pitching screen.
In some implementations of the disclosure, a sturdier screen can be shipped by residential carriers in a traditional size box or a smaller box size. The screen also can be disassembled, transported into buildings through regular 3′×7′ doorways, and taken off the field and stored during the off season. The screen is also capable of modular part replacement. Should one of the areas of the screen become dented or damaged by a baseball or object hitting it, the part could be replaced and bolted into place. As such, implementations provide an opportunity to reduce life cycle cost.
A variety of implementations and configurations of the members that can be used to complete a pitching screen frame using structure 17 can be provided. The following examples inform one of ordinary skill in the art concerning such implementations.
To further depict that the rigid structural component according to the disclosure can take a variety of forms,
The above disclosure described a rigid component centrally located in a pitching screen frame, which provides a plurality of attachment points, that are used to couple to other components, in order to complete the frame. In some portions of the description, such rigid component was described as being formed of steel and welded. Welding is an example of how such rigid component can be formed, but is not by exclusion of other approaches. For example, another approach may be to adhere separately formed components together with a glue or epoxy. For example, an end user may receive separate components and adhere them together to form the rigid structure. In general, however, it is anticipated that a welded rigid member will be cheaper and more user friendly. Materials other than steel may be used, although steel is a comparatively strong and light weight material, compared to more exotic materials. The steel may be of an appropriate gauge and shape. The steel may have a square, round, or rectangular cross section, for example. The ends of the steel may be swaged. The steel may be galvanized or painted.
The figures depict various examples of rigid and generally planar frame components that are formed to receive elongate components in order to form a pitching screen. For example, a triangular component can be located generally at a lateral center of a pitching screen and accept a lateral tube to complete a top edge of the bottom part of the L. In some examples, the frame component extends from a bottom edge to a top edge of the L screen, where the bottom edge forms a T with respect to a vertical part of the rigid member. The rigid member can accept a tube to complete the vertical portion of the L, Bolt or snap together components can be used to complete the remaining portions of the pitching frame.
These examples show how a pitching screen can be made more rigid by a rigid central member that can attach to other components in order to complete a desired frame configuration. One example frame configuration is an L shaped pitching screen. The description and claims at times use the term ‘planar’ to describe a characteristic of the rigid member that includes locations at which other components can attach in order to complete the frame of the pitching screen. This terminology is not by way of excluding elements of the rigid member that are not within the plane of the pitching screen, but rather is directed to a characteristic that the rigid member includes at least a portion that is planar in the plane of the pitching screen, even though other portions of the rigid member are non-planar. Also, where the rigid member includes non-planar portions, these portions may not be welded or rigidly attached. Thus, implementations of this disclosure fully encompass these additions and changes to the examples disclosed.
Components can be assembled to the rigid component or to other components using bolts, snaps, adhesives, or combinations thereof. Where disassembly is required, adhesives would be avoided. The components that attach to the rigid member can be referred to as “bolt together components”, for the sake of convenience. The bolt together components can be provided in a variety of shapes, sizes, and can have angles, bends or turns additionally. As such, the figures do not imply any particular limitation on how the bolt together components can be arranged or formed, but rather depict a variety of examples to show the breadth of approaches that conform to the disclosures herein.
