BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a batting practice set, and more particularly, to a batting practice set with a base in which a weight is received so that the device is set firmly on the ground.
2. The Prior Arts
A conventional baseball batting practice set includes a base and a rod extends from a top of the base. The base generally is made by rubber which is heavy enough so that when the base does not move when practicing. However, the price of the rubber is getting higher and higher that the cost for the baseball betting practice device cannot keep the device to be competitive in the market.
SUMMARY OF THE INVENTION
A primary objective of the present invention is to provide a batting practice set which includes a weight received in the base which is set firmly on the ground and the material for the weight is less expensive and easily got.
According to the present invention, a batting practice set is provided and comprises a base having first and second walls extending from an underside thereof and a receiving space is defined between the first and second walls. A rod is connected to a top of the base and a weight is received in the receiving space. A cover is connected to the underside of the base and covers the receiving space. A securing unit secures the cover to the base. Thanks to the weight, the batting set is firmly set on the ground.
The shape of the receiving space can be rectangular, ring-shaped, or square and the material for the weight can be pebbles, sands or cement.
By using the weight of the present invention, the price can be reduced when compared with the use of rubber for the conventional batting set. Even if the weight is not sold with the batting set, the user can collect pebbles, cement or any material at hand to be the weight. The batting set can be easily stored and the base does not move when using the batting set.
The material of the weight can be easily removed to reduce the weight of the whole batting set so as to be conveniently carried.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to the drawings and in particular to FIG. 1, a batting practice set in accordance with the present invention comprises a base 1, a weight 2, a cover 3 and a securing unit 4. The securing unit 4 includes a first part 41 and a second part 42. The base 1 includes first and second walls 11, 12 extending from an underside thereof, and a receiving space 13 is defined between the first and second walls 11, 12. The weight 2 is received in the receiving space 13 and the cover 3 is connected to the underside of the base 1 and covers the receiving space 13. The securing unit 4 securely connects the cover 3 to the base 1 so that the weight 2 is received in the receiving space 13. When in use, a rod 5 is connected to a top of the base 1.
With reference to FIGS. 1 and 2, the second wall 12 has a larger diameter than the first wall 11 so that the receiving space 13 is defined between the first and second walls 11, 12. The shapes of the first and second walls 11, 12 are not limited to the shapes as shown and can be any desired shape such as round, square, rectangle, or pentagon. A first space 14 is defined within the area enclosed by the first wall 11. The base 1 includes a first through hole 15 defined therethrough which is located at the center of the base 1 and in the first space 14 enclosed by the first wall 11. The inner diameter of the first through hole 15 is smaller than that of the first space 14. The second wall 12 of the base 1 includes a flange 121 extending from an outer periphery thereof and a plurality of ribs 16 are connected between the second wall 12 and peripheral sidewalls of the base 1. In this embodiment, the weight 2 is made by cement, however, the material for the weight 2 can be pebbles or sands and is filled in the receiving space 13 when using the batting practice set. The cover 3 has a tubular protrusion 31 extending from a center thereof and a peripheral wall 32 extends from a periphery of the cover 3. The tubular protrusion 31 has a lip 321 extending inward from an inner periphery thereof and the tubular protrusion 31 encloses a stepped passage 33.
The first part 41 of the securing unit 4 includes a second through hole 411 which includes a first inner threads 412 and the second part 42 includes first outer threads 421. The first part 41 is located on the top of the base 1 and the second part 42 extends through the passage 33 and the first through hole 15 and are threadedly connected with the first part 41 so as to connect the cover 3 to the base 1. The securing unit 4 further includes a sleeve 43 which is mounted to the first part 41 and connected with the rod 5. The sleeve 43 includes second inner threads 431 and third inner threads 432, wherein the inner diameter of the second inner threads 431 is larger than that of the third inner threads 432. The rod 5 has third outer threads 51 at a lower end thereof and the third outer threads 51 are connected with the third inner threads 432. The first part 41 further has second outer threads 413 which are connected with the second inner threads 431. The method for connecting the rod 5 to the base 1 is not limited the embodiment disclosed above.
Referring to FIGS. 1 to 3, when assembling the batting practice set, the weight 2 is received in the receiving space 13 and the thickness of the weight 2 does thicker than the height of the first and second walls 11, 12. The tubular protrusion 31 of the cover 3 is then inserted in the first space 14 so as to align the passage 33 and the first through hole 15. The underside of the cover 3 is in contact with the end surfaces of the first and second walls 11, 12, the lip 321 and the flange 121 are engaged with each other so as to position the cover 3 to the base 1. The underside of the cover 3 is in flush with the underside of the sidewalls of the base 1. The first part 41 is then put on the top of the base 1 and the second through hole 411 is in alignment with the first through hole 15, the second part 42 is then inserted through the passage 33 and the first through hole 15 and is threadedly connected to the first part 41. The rod 5 is then connected to the third inner threads 432 of the sleeve 43 whose second inner threads 431 are connected to the second outer threads 413 of the first part 41.
FIG. 4 shows another embodiment of the connection of the cover 3 and the second wall 12, wherein the cover 3 includes a circular peripheral wall 32 and second inner threads 322 are defined in an inner periphery of the peripheral wall 32, the second wall 12 is a circular wall and includes second outer threads 122 defined in an outer periphery thereof, the second inner threads 322 are engaged with the second outer threads 122.
FIG. 5 shows that the rod 5 is fixed to the top of the base 1 by the sleeve 43. The weight 2 and the cover 3 are hidden by the base 1 so that the base 1 is heavy and does not move when using the batting practice set. The material for the weight can be sands or pebbles which are easily obtained and can be filled in the receiving space 13 when assembling the batting practice set. The pebbles or sands are removed from the receiving space 13 after use. This makes the user to easily carry the batting practice set.
Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
