This invention relates to a tee ball stand. More specifically, this invention relates to a tee ball stand which is fully collapsible for compact, lineal storage and which has a weighted base to resist tipping when inadvertently struck with a bat.
Tee ball stands are characteristically used in the process of teaching young children to hit a ball with a bat. The typical tee ball stand comprises a flat, ground engaging plate, most often in the shape of a baseball home plate, which supports an adjustable vertical pole having a ball support cup on the upper end. A ball is placed on the support cup so a youngster can then strike at the stationary ball by swinging a bat instead of the more difficult task of attempting to hit a moving ball. With limited experience or limited coordination, the youngster may occasionally strike the cup or pole holding the ball, rather than the ball itself. This can be expected as part of the learning process. As a result, however, the tee ball stand is frequently tipped over or moved and has to be repositioned for the training session to continue. This can be a source of frustration and discouragement, as well as a safety concern, for the youngster and coach in the event of inadvertent contact with errant bat swings.
U.S. Pat. Nos. 4,227,691, 4,709,924, 4,819,937, 4,962,924, 5,004,234, 5,916,045, 6,099,418 and 6,884,185, as well as others, are characteristic of various tee ball practice devices having a base plate that rests flat on the ground to support some type of ball holding apparatus.
Even though some of the prior art references disclose a telescopingly adjustable vertical pole, one can easily appreciate the problem of storing a tee ball stand with a large base plate when the equipment is not in use. My U.S. Pat. No. 8,734,274 offered some alternative solutions for storage by proposing an X-frame base that was either foldable alongside the vertical stanchion or disassembled. In either case, the overall length was not optimal for original merchandise packaging and the tee ball stand proved to be slightly unstable when struck with an errant bat.
Therefore, a need remains in the field of youth sports for a tee ball stand that can be easily and quickly assembled from a condition of compact lineal storage and that will be tip resistant when inadvertently struck with a bat. The primary objective of this invention is to meet these needs.
More specifically, an object of the invention is to provide a tee ball stand that will yield from an upright orientation in the event it is struck with an errant bat of a youngster so as to protect the user from experiencing the shock of impact, but, at the same time, the tee ball stand will remain in or return to a preselected location on the ground.
Another object of the invention is to provide a tee ball stand with an upright stanchion including a flex connection with the base to readily deflect when the stanchion is struck by an errant blow of a bat and then return to an upright position.
A corollary object of the invention is to provide a tee ball stand of the character described including a weighted base to assist in combination with the flex connection to resist tipping of the tee ball stand when struck by an errant bat swing.
Another object of the invention is to provide a tee ball stand of the character described wherein the upright stanchion is telescopically adjustable to accommodate youngsters of varying heights.
A further object of the invention is to provide a tee ball stand easily assembled or disassembled without tools for minimal lineal packaging or storage.
Yet another object of the invention is to provide a tee ball stand for minimal lineal packaging or storage wherein the component parts are removably interconnected by friction fit.
In summary, an object of the invention is to provide a tee ball stand with a ball holder fitted to a two-piece adjustable stanchion received by a flex sleeve supported from a base hub. Weighted legs formed from hexagonal tubing are fitted at right angles into hex sockets of the base hub to prevent twisting. The outer ends of the legs are closed with an end cap having a ground engaging spur to resist sliding on the ground.
Other and further objects of the invention, together with the features of novelty appurtenant thereto, will appear in the course of the detailed description of the drawings.
In the following description of the drawings, in which like reference numerals are employed to indicate like parts in the various views:
FIG. 1 is a perspective view of a tee ball stand constructed in accordance with a preferred embodiment of the invention;
FIG. 2 is an exploded view of the tee ball stand shown in FIG. 1 to illustrate the component parts of the assembly;
FIG. 3 is an enlarged side elevational view of the base hub fitted with a flex sleeve and showing fragmentary views of the base legs and stanchion with the flex sleeve slightly tilted as if hit by an errant bat swing;
FIG. 4 is an enlarged side elevational view of the base hub similar to FIG. 3 but showing the middle base leg and middle hub socket in section to illustrate the interconnection of these parts; and
FIG. 5 is a side sectional view of a base leg of the tee ball stand as weighted with sand, gravel, or the like.
Referring to the drawings in greater detail, the tee ball stand 10 includes a conical ball holder 12 adapted to support a ball 14 such as a baseball, softball, or similarly sized training ball. The ball holder 12 is removably installed by friction fit on the end of telescoping, upper stanchion tube 16. Tube 16 is cylindrical and sized with an outside diameter to slidably fit within the inside diameter of the cylindrical, lower stanchion tube 18. The overall height of the stanchion tubes 16 & 18 can be adjustably fixed by tightening the locking nut 20 on the uppermost end of the lower stanchion tube 18 in a manner commonly used in tee ball stands previously known in this art.
The lower stanchion tube 18 is removably installed by friction fit to a flex sleeve 22 having a corrugated portion 22a to permit slight flexure as shown in FIG. 3 when the ball holder 12, or stanchion tubes 16 or 18 are inadvertently struck with a bat. The flex sleeve 22, in turn, is removably installed by friction fit to a transition fitting 24 which may be a separate piece as illustrated or part of the base hub 26.
The base hub 26 has an upright socket 26a which receives the transition fitting 24 by friction fit or permanently joined thereto. The base hub 26 also includes four horizontal sockets 26b arranged at right angles to each other. Braces 26c are joined between the upright socket 26a and the horizontal sockets 26b. Interiorly, the horizontal sockets 26b are hexagonal in cross sectional shape as shown in FIG. 4.
Each horizontal socket 26b of the base hub 26 removably receives by friction fit a base leg 28. The base legs 28 are hexagonal in cross sectional shape (see FIG. 4) so as to prevent twisting or rotation when installed in the socket 26b of hub 26.
As shown in FIG. 5, each leg 28 includes a hexagonal tube 28a closed at each end with a plug 28b. Weighting material 28c, such as sand, gravel, lead shot, or the like, fills the interior of the tube 28a between the end plugs 28b.
The outer end of each leg 28 is fitted with an end cap 30 having a ground engaging spur 30a which registers with one of the flat hexagonal surfaces of the leg 28. It is intended that the leg 28 be inserted into a socket 26b of the hub 26 such that the spur 30a of the end cap 30 is oriented downwardly to engage the ground when the tee ball stand 10 is fully assembled. This prevents the tee ball stand 10 from sliding along the ground.
The tubular parts of the tee ball stand 10โnamely, upper stanchion tube 16, lower stanchion tube 18, and base legs 28โare all of comparable lengths. When disassembled, either for original merchandise packaging or for storage, this permits extremely compact positioning of the component parts. Assembly of the components is easily accomplished since all may be friction fitted together by hand without the need for installation tools. Disassembly is equally easy by simply reversing the assembly process and pulling the components apart for separation and storage.
From the foregoing it will be seen that this invention is one well adapted to attain all the ends and objects hereinabove set forth, together with the other advantages which are obvious and which are inherent to the invention.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
