An "L" shaped protective screen is provided within the batting practise cage for the coach to stand behind as he pitches the ball to the batters . There have been batting cages marketed as being "portable" but to date these portable batting cages still require a considerable amount of time for assembly.
2 0 SUN~IARY OF THE INVENTION
What is required is a portable batting cage that can be rapidly erected with a minimum of assembly.
According to one aspect of the present invention there is provided a portable batting practise cage which includes several support poles and a non-supporting mesh shell. The shell has a substantially planar end wall, depending anchor lines and several transversely extending rows of externally positioned loops. The shell is supported and held erect by inserting one of the several support poles through each of the several transversely positioned rows of externally positioned loops, and anchoring the mesh shell to a ground surface by means of the anchor lines. A pitching port is provided through the planar end wall of the shell.
According to another aspect of the present invention there is provided a method of using the described structure of portable batting practise cage. A structure, as described above, is first obtained and erected. A pitcher is then positioned outside of the structure. The pitcher pitches balls through the pitching port to a batter positioned inside of the structure.
The described batting practise cage structure and its method of use are believed to represent a paradigm shift in thinking regarding batting cages. In terms of the method of use, prior batting cages required both the pitcher and the batter to be positioned within the batting cage . This required the batting cage to be of a sufficient size to accommodate both the pitcher and the batter. The distance between the pitcher and the batter in professional leagues is 60 feet. The distance between the pitcher and the batter in amateur leagues is 48 feet. Although it has never been a requirement that batting cages be of a regulation distance, most batting cages are manufactured to a length of over 40 feet. With the present method the pitcher is positioned outside of the batting cage. There need only be sufficient room for a batter to function comfortably, as a consequence a much smaller structure can be utilized. The pitcher can, of course, stand any desired distance away from the pitching port of batting practise cage.
The only limitations are practical considerations. One practical consideration is the ability of the pitcher to accurately pitch the ball through the pitching port to the batter strike zone from a given distance. Another practical consideration is having the batter far enough back from the pitching port that it is unlikely that he will drive the ball back out through the pitching port. In terms of the structure, as will hereinafter be further described, the batting practise cage is intended to more closely resemble a tent, than prior art batting cage structures. Unlike a tent, in order to function as a batting cage the shell must have a planar face where a pitching port is located. The poles must be exterior to the shell, as otherwise the light weight poles would be exposed to balls and would shatter upon impact.

Although beneficial results may be obtained through the use of the portable batting practise cage, as described above, even more beneficial results may be obtained through the addition of selected features and combinations of features, as will hereafter be further described. It is preferred that a domed shell be used. It is preferred that each of the several support poles be capable of bending to assume an arch configuration. It is preferred that foldable poles be used with a plurality of interlocking sections held together with a flexible line, such as are now becoming popular with tents.
It is preferred that ends of each of the several transversely extending rows of externally positioned loops terminate in pole engaging members so that the poles can be slid through the loops and engaged with the pole engaging members to maintain them in an arch configuration. For reasons of safety, it is preferred that a closure be provided for blocking off a portion of the pitching port and reducing the likelihood of the batter driving a ball back through the pitching port.

Referring to FIGURE 1, there is provided a portable batting practise cage 10 which includes several flexible support poles 12 and a non-supporting mesh dome shell 14.
Support poles 12 have opposed ends 16 and are capable of bending to assume an arch configuration. Referring to FIGURE
7, support poles 12 consist of a plurality of interlocking sections 18 held together with a flexible line 20 that enables support poles 12 to be folded for storage.
Referring to FIGURE 6, dome shell 14 has a substantially planar end wall 22, depending anchor lines 24 and several transversely extending rows of externally positioned loops 26.
In the illustrated embodiment, dome shell 14 is depicted as having upper anchor lines 28 or lower anchor lines 30.
Referring to FIGURE 4, upper anchor lines 28 terminate in a loop 44. Referring to FIGURE 5, lower anchor lines 30 have grommets 34 which server as pole engaging members. Referring to FIGURES 2 and 6, a pitching port 36 is provided through planar end wall 22 of dome shell 14. An lower closure 38 is provided for blocking off an lower portion 39 of pitching port 36 and an upper closure 41 is provided for blocking off an upper portion 43 of pitching port 36. Referring to FIGURE 7, portable batting practise cage 10 fits into a small carrying bag 60. Carrying bag 60 is 14 inches high, 14 inches wide and 42 inches long. The weight is approximately 50 pounds and, as such, can easily be carried by one person.
5 Operation:
The use and operation of portable batting practise cage will now be described with reference to FIGURES 1 through 7. Referring to FIGURE 7, portable batting practise cage 10 is transported to the site of the practise in carrying bag 60.
10 Once at the site, support poles 12, non-supporting mesh shell 14 and ground spikes 42 are removed from carrying bag 60.
Foldable support poles 12 are then assembled. Referring to FIGURE 3, portable batting practise cage 10 is erected by inserting one of flexible support poles 12 through each of transversely positioned rows of externally positioned loops 26.
Referring to FIGURE 5, opposed ends 16 of support poles 12 are secured to grommets 34 of lower anchor lines 30 to maintain each of support poles 12 in an arcuate orientation. Although in the illustrated embodiment, pole engaging members are depicted as being grommets 34, it will be appreciated that there are other means available which could function as pole engaging members. Referring to FIGURE 6, mesh dome shell 14 is anchored to a ground surface 40 by means of upper anchor lines 28. Referring to FIGURE 5, upper anchor lines 28 are secured to ground surface 40 by inserting ground spikes 42 though loops 33 and then into ground surface 40.
Referring to FIGURE 6, in use, a pitcher 46 positions himself outside of the dome shell 14. Pitcher 46 then pitches balls 48 through port 36 to a batter 50 positioned inside of dome shell. Either lower closure 38 is used to block off lower portion 39 of pitching port 36 or upper closure 41 is used to block off upper portion 43 of pitching port 36. This is done to reduce the likelihood of batter 50 driving ball 48 back through pitching port 36. Pitcher 46 can stand back any desirable pitching distance from port 36. V~lhich closure 38 or 41 is used will depend upon whether the pitcher pitches overhand style such as is common for hard ball or underhand style such as it common for soft ball.
Referring to FIGURE 7, portable batting practise cage 10 can be erected or collapsed in the time it would take to erect a tent. Once collapsed, non-supporting mesh shell 14, foldable poles 12, and ground spikes 42 can be stuffed back into carrying bag 60.
