The present technology provides a telescoping or collapsible batting tee that extends or collapses to accommodate different batters and to improve portability of the tee. Examples of this technology are illustrated in FIGS. 1-6.
Turning now to the drawings, FIGS. 1 and 2 illustrate a batting tee 100 in accordance with an embodiment of the present technology. A base portion or base 110 supports concentric telescoping rods 115 including a first or lower rod 120, a second or intermediate rod 130, and a third or upper rod 140. The base 110 may support the rods 115 by way of an attachment portion 150 that holds the lower rod 120 upright. The telescoping rods 115 support a ball holder 160, which may support a ball 170 in a position for a batter to hit. As illustrated in FIGS. 1 and 2, the rods 115 can telescopically collapse and extend so that the tee 100 has an adjustable height. In particular embodiments, the upper rod 140 may have an outer diameter of approximately 0.75 inches, the intermediate rod 130 may have an outer diameter of approximately 1 inch, and the lower rod 120 may have an outer diameter of approximately 1.5 inches. In other embodiments, the rods 115 may have other suitable diameters. The rods 115 may have various lengths suitable for accommodating users of different height ranges.
A first or lower collar 180 may be attached to the lower rod 120 and positioned to allow the intermediate rod 130 to pass therethrough with sufficient friction to maintain the rods in a desired position. In some embodiments, the collar 180 may be glued or otherwise fastened to the lower rod 120. Similarly, a second or upper collar 190 may be attached to the intermediate rod 130 and positioned to allow the upper rod 140 to pass therethrough with sufficient friction to maintain the rods in a desired position. In some embodiments, the collar 190 may be glued or fastened to the intermediate rod 130. In other embodiments, the collars 180 and 190 may be sized such that they do not provide sufficient friction to maintain the height of the tee, and they may instead work in conjunction with the O-rings described below to maintain the tee's height.
The base 110 may comprise a heavy rubber material or other material suitable for providing a solid or resilient support for the tee 100 on the ground. The telescoping rods 115 may be made of aluminum, fiberglass, carbon fiber, plastic, rubber, or other suitable structural materials. In one embodiment, the lower rod 120 and the intermediate rod 130 may be made of aluminum, while the upper rod 140 may be made of fiberglass. The attachment portion 150 may be made of aluminum, steel, plastic, or another suitable structural material.
Turning now to FIG. 3, a ball holder 160 is shown mounted atop the upper rod 140. In some embodiments, the ball holder 160 may comprise a generally tubular structure such as a roll, tube, or cone made of rubber or another suitably resilient material. Optionally, as illustrated in FIG. 1, for example, the ball holder 160 may include slots, notches, or cutouts 165 extending downward from the top of the ball holder 160 to vary the flexibility of the ball holder 160. Returning to FIG. 3, the ball holder 160 may be attached to the upper rod 140 with tape or a sleeve 300, or with glue or another adhesive. With reference now to FIG. 4, in some embodiments, the ball holder 160 may be releasably attached to the upper rod 140 using a threaded bolt 460. In other embodiments, the ball holder 160 may be attached to the upper rod 140 using other suitable removable or permanent attachments.
The attachment portion 150 may include an attachment cup 400 that receives an end of the lower rod 120. The attachment portion 150 may also include an attachment plate 405 to provide stability to the attachment portion 150 on the base 110. The attachment portion 150 may further include a threaded attachment-plate extension or rod 410, which may mate directly with threads in the base 110, or with a threaded bore 415 in a lower plate 420. The lower plate 420 may be received in a corresponding recess 425 in the base 110. In some embodiments, the attachment cup 400 may be attached or mounted to the base 110 in other suitable ways.
Aspects of the telescoping rod mechanism are now described with reference to FIGS. 4 and 5. A first O-ring 430 may be positioned around a portion of the intermediate rod 130. The intermediate rod 130 with the first O-ring 430 may be telescopically received in the lower rod 120. The thickness of the O-ring 430 generally fills the gap between the lower rod 120 and the intermediate rod 130. The O-ring 430 provides friction or resistance to telescoping motion between the lower rod 120 and the intermediate rod 130 as it rolls or slides between an outer diameter of the intermediate rod 130 and an inner diameter of the lower rod 120. In some embodiments, additional O-rings may be used to modify the resistance to telescopic expansion or collapse.
To retain the O-ring 430 on the intermediate rod 130, a first rod cap 435 may be installed on the end of the intermediate rod 130 within the lower rod 120. The first rod cap 435 may be in the form of a washer 437 and a fastener or screw 439 threaded into the end of the intermediate rod 130. In another embodiment, the first rod cap 435 may be pressed or threaded directly into the intermediate rod 130, or it may be integral with the intermediate rod 130.
The washer 437, rod cap 435, or other element includes a diameter large enough to block the O-ring 430 from falling from the intermediate rod 130 into the lower rod 120. The lower collar 180 also optionally prevents the O-ring 430 from falling from the intermediate rod 130 into the lower rod 120. The lower collar 180 may be attached to the lower rod 120 with a portion of the lower collar 180 on the inside of the lower rod 120, and a portion of the lower collar 180 on the outside of the lower rod 120. The intermediate rod 130 passes through the lower collar 180 while the lower collar 180 may resist passage of the O-ring 430 out of the lower rod 120. In some embodiments, the lower collar 180 may be sized to provide sufficient friction between the lower collar 180 and the intermediate rod 130 to help maintain the tee 100 at a desired height.
The telescoping connection between the intermediate rod 130 and the upper rod 140 may be similar to the telescoping connection between the lower rod 120 and the intermediate rod 130. A second O-ring 440 may be mounted on the upper rod 140 within the intermediate rod 130 to provide friction between the upper rod 140 and the intermediate rod 130 as the upper rod 140 moves telescopically within the intermediate rod 130. A second rod cap 445 may retain the second O-ring 440 on the upper rod 140 within the intermediate rod 130. The second rod cap 445 may include a washer 447 and a fastener or screw 449 threaded onto the lower end of the upper rod 140, or it may be pressed or threaded directly into the upper rod 140, or it may be integral with the upper rod 140. The second rod cap 445 has a diameter large enough to block the second O-ring 440 from falling from the upper rod 140 into the intermediate rod 130. Similar to the lower collar 180, the upper collar 190 resists passage of the second O-ring 440 out of the intermediate rod 130 and it may also prevent the second O-ring 440 from falling from the upper rod 140. The upper collar 190 may be sized to provide sufficient friction between the upper collar 190 and the upper rod 130 to help maintain the tee 100 at a desired height. In some embodiments, the O-rings 430 and 440 may comprise silicone, rubber, or other resilient or flexible materials.
As described above with respect to FIG. 3, in some embodiments, the ball holder 160 may be mounted to the upper rod 140 using a tape or sleeve 300. Turning again to FIGS. 4 and 5, the ball holder 160 may additionally or alternatively be mounted to the upper rod 140 using a ball holder mount 450. The ball holder mount 450 may include a ball holder cap 455 installed on the upper rod 140 with a threaded rod, bolt 460, or other fastener that retains the ball holder 160. The threaded rod or bolt 460 may optionally mate with an adjoining nut or threaded portion in the upper rod 140.
In some embodiments, as shown in FIG. 4, for example, the threaded portion in the upper rod 140 may be a threaded plug 462 or other threaded receiving element pressed into an opening 463 in a side of the upper rod 140. In other embodiments, as shown in FIG. 5, for example, the threaded receiving portion may be fixed in the top end of the upper rod 140.
In some embodiments, the threaded fastener may be a screw or bolt 460 that passes through the ball holder cap 455 and the bottom of the ball holder 160 such that it is accessible for tightening by reaching into the ball holder 160 by hand or with a tool. In other embodiments, the cap 455 may be installed by pressing it onto the upper rod 140 without the need for a threaded rod, bolt 460, or other fastener.
Turning to FIG. 6, the lower rod 120 may have a groove 610 configured to receive a lug 620 extending from an interior surface of the attachment cup 400. When the lower rod 120 is positioned in the attachment cup 400, the lug 620 first slides through a vertical portion of the groove 610. The lower rod 120 may then be locked into the attachment cup 400 by rotating the lower rod 120 so that the lug 620 slides through a horizontal portion of the groove 610. In this manner, the lower rod 120 may be releasably locked into the attachment portion 150. Accordingly, the rods 115 may be readily attached to, and removed from, the base 110.
From the foregoing, it will be appreciated that specific embodiments of the disclosed technology have been described for purposes of illustration, but that various modifications may be made without deviating from the technology, and elements of certain embodiments may be interchanged with those of other embodiments. For example, in some embodiments, only two telescoping rods 115 may be used, and in other embodiments, more than three telescoping rods 115 may be used. In other embodiments, the base attachment portion 150 may be integral with the base 110.
Further, while advantages associated with certain embodiments of the disclosed technology have been described in the context of those embodiments, other embodiments may also exhibit such advantages, and not all embodiments need necessarily exhibit such advantages to fall within the scope of the technology. Accordingly, the disclosure and associated technology may encompass other embodiments not expressly shown or described herein, and the invention is not limited except as by the appended claims.
