FIELD OF THE INVENTION
This invention relates to a pole vaulting device. More specifically, but not by way of limitation, this invention relates to a pole vaulting net device and method.
BACKGROUND OF THE INVENTION
Pole vaulting is an exciting, challenging sport. In the early days of the sport, the poles utilized were made of bamboo and the pit contained saw dust. Now, the poles are made of high tech synthetic plastics and the pits contain mats. The poles are longer and stronger, and the athletes are jumping ever higher distances. As those active in the sport will recognize, greater heights entail greater risk.
One of the most common injuries are those associated with the pole vaulter landing improperly onto the mat. In other words, after the pole vaulter utilizes the pole to vault him (or her) into the air, the pole vaulter may land in such a way that causes serious injuries to him (or her). For instance, the pole vaulter may land face forward in the vaulter's planting box, or the pole vaulter may completely miss the mat, or the pole vaulter may bounce off the mat and onto the ground. This list is illustrative. Since 1971, there have been at least 45 catastrophic injuries or deaths which have occurred due to pole vaulting activities.
Prior art vaulting techniques include utilization of mats. However, this safety technique requires the horizontal application of mats, which may be cost prohibitive. Additionally, many track and field areas have limited space thereby limiting the usefulness of large horizontal mats. Further, some prior art techniques use specialized mats. However, these designs still require the application of horizontal mat placement to solve the problem. Further, these prior art designs are awkward and expensive.
Therefore, there is a need for a device that will allow for safer pole vaulting. There is also a need that will allow for a netting device for use in pole vaulting. There is also a need for a pole vaulting device that can distribute the forces caused by the falling and bouncing athlete. These needs, and many others, will be met by the following disclosure.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to FIG. 1A, a top view of the preferred embodiment of the base frame 2 for the present invention will be described. The base frame 2 may sometimes be referred to as the grid 2. The base frame 2 includes a longitudinal beam means (sometimes referred to as length), a latitudinal beam means (sometimes referred to as width) and diagonal beam members. The longitudinal beam, the latitudinal beam, and the diagonal beams, in the most preferred embodiment, are channel bar segments, as will be more fully explained later in the application. The longitudinal beam means contains member 4a, member 4b, member 6a, member 8b, member 8a and member 8b, wherein members 4a and 4b cooperate to form a first variable length beam, members 6a and 6b cooperate to form a second variable length beam, and members 8a and 8b cooperate to form a third variable length beam. On the opposite side, the longitudinal beam means contains the member 10a, member 10b, member 12a, member 12b, member 14a, and member 14b, wherein members 10a and 10b cooperate to form a fourth variable length beam, members 12a, 12b cooperate to form a fifth variable length beam, and members 14a, 14b cooperate to form a sixth variable length beam.
The latitudinal beam means contains member 16a, member 16b, member 18a, member 18b, member 20a, member 20b, member 22a, and member 22b. The beam means also include the diagonal variable length beams that include member 22b, member 24a, and member 24b, member 26a and member 26b. As seen in FIG. 1A, members 16a and 16b form a seventh variable length beam, members 18a and 18b form an eight variable length beam, members 20a and 20b form a ninth variable length beam, members 22a and 22b form a tenth variable length beam. The members 24a and 24b form a variable length beam, and members 26a, 26b form a diagonal variable length beam.
Referring now to FIG. 1B, an expanded, rotated view of the channel bar beam seen in FIG. 1A taken along line 1B-1B will now be described. More specifically in FIG. 1B, the member 4a and member 4b are shown, and wherein the members 4a/4b are channel bar segments as noted earlier. Additionally, the wing nut 28 and bolt 29 are shown disposed through perforated apertures in the channel bar segments. In the preferred embodiment, each individual length beam member will be slidably connected in this way. Another variable length arrangement may be used that includes a tongue in groove arrangement. For instance members 4a and 4b may be slidably connected by a tongue in groove arrangement, and can be fastened by fastener means such as a screw and wing nut (the tongue and groove embodiment not shown). Referring now to FIG. 1C, a partial perspective view of the beam member (channel bar segment) 4a is shown, along with apertures, such as 1a, 2a, 3a, for placement of the wing nuts and bolts. Hence, the length of the beams can be varied and are therefore adjustable in length.
Returning to FIG. 1A, FIG. 1A depicts member 4a and member 16a are connected by conventional means such as nuts and bolts, seen generally at 28. FIG. 1A shows the stands, such as stand 32. FIG. 1A further depicts the cylindrical sleeve of the stand 32 which the support poles can be placed therein. The support poles and stands will be described later in the application. Hence, FIG. 1A depicts the openings 30a, 30b, 30c, 30d, 30f, 30g, 30h, 30i of the various stands for placement of the support poles. FIG. 1A also depicts the contour of the net N, as will be more fully explained later in the application.
As per the teachings of the present invention, the base frame 2 is constructed so as to make it possible to vary the length and width in order to accommodate various size mats. Hence, an operator can adjust the length of each beam by simply sliding or expanding members, and thereafter bolting the cooperating members together. For instance, member 4a and member 4b can be shortened by simply sliding the two members together, as well as sliding members 10a and 10b together. Additionally, with the design of the present invention, the base frame 2 can be disassembled after use and moved to another location or stored.
Referring now to FIG. 2A, a partial side view of the preferred embodiment of the support pole and stand of the present invention will now be described. Generally, the stand 32 has a base 34 that has two (2) supporting braces 36, 38, as well as the tubular sleeves 40, 42 which will have the cylindrical pole 44 disposed there through. The cylindrical pole 44 is sometimes referred to as the support pole. The tubular sleeve 42 is attached on top of channel bar segment 46; braces 36, 38 attach to sleeve 40. Channel bar segment 46 is used, along with the tubular sleeve 40 and 42 to attach the pole 44 to the frame 2, and wherein the channel bar segment 46 is one of the adjustable beams 2, as previously described. The channel bar segment 46 may be attached to the stand via nut and bolt means; tack welding could also be used. The support pole 44 has the first end disposed through the tubular sleeves 40, 42.
As seen in FIG. 2B, which is a partial side view of the support pole 44 seen in FIG. 2A rotated 90 degrees, the second end of the support pole 44 has the curved portion 48. As will be explained in greater detail later in the application, the curved portion 48 will be oriented in the direction of the mat. At the end of the curved portion 48 is the eyelet 50, and wherein the eyelet 50 can be used to attach to the net, as will be more fully explained. FIG. 2B depicts the distance “L” from the eyelet to the vertical segment of the pole 44.
FIG. 3 is a partial top view of a mat 52 placed on top of the base frame 2 seen in FIG. 1. It should be noted that like numbers appearing in the various figures refer to like components. In FIG. 3, the pole vaulter's planting box 54 is shown, along with the cutaway in the mat 52 so that the planting box 54 can be surrounded on three sides by the mat, as is well understood by those of ordinary skill in the art. FIG. 3 depicts support poles 56, 58, 60, 62, 64, 66, 68, 70 which are placed within their respective stands. The variable length beams are shown in hatched format since the mat 52 is positioned on the top of the base frame 2. As those of ordinary skill in the art will recognize, the cutaway parts 71a, 71b of the mat near poles 56, 70 represent the location of the standards which support the cross-bars. Note that the support poles 56-70 are set back from the edge of the mat due to the distance from the vertical part of the pole to the eyelet, which is at least the previously discussed distance “L”. This distance is allowed due to the curved top portion and allows a distance from the pole to the net so that the vaulter does not hit the support pole while bouncing in the bowl section of the net, as will be discussed in further detail later in the application. FIG. 3 also depicts the three-sided nature of the net since one side will have to be open to allow the vaulter through. The open side corresponds to the side adjacent the planting box 54 and denoted by the letter “O” in FIG. 3.
Referring now to FIG. 4, a front view of the preferred embodiment of the pole vaulting device of the present invention will now be described. The support pole 70 is shown disposed within a stand, and where the brace 72 of a support stand is shown and wherein the stand is attached to the base frame 2, using conventional means. The beam members are attached to each other such as seen, at point 73. The support pole 56 is shown within a stand and where the brace 74 is shown and wherein the stand is attached to the base frame, using conventional means. The support poles 62, 64 are also shown in this view. Note that in this embodiment, the distance from the support pole 70 to the edge of the mat is the previously described distance “L”. The support pole 70 has the curved portion 76 with eyelet 78, and the support pole 56 has the curved portion 80 with eyelet 82. In one preferred embodiment (not shown), there may be three layers of mats. Other mat configurations are possible such as the mats being in blocks that are positioned adjacent each other, with a top blanket covering the mats. The curved portions 76 and 80 are oriented in the direction of the mat 52 so that the vaulter does not strike the poles 70, 56.
FIG. 4 further depicts the net, seen generally at 84. The net 84 has an outer periphery which runs along the top of the net 84, denoted by the numeral 85. According to the teachings of the present invention, the net 84 wilt have at one end a connection to the support poles, and more specifically, to the curved portions. Therefore, the outer periphery 85 of the net 84 will be attached to the eyelet 78 at point 86. Likewise, the outer periphery 85 of the net 84 will be attached to the eyelet 82 at point 88. The outer periphery 85 of the net may have a cable “C” disposed therein, and wherein the cable “C” can be connected to the eyelets. The outer periphery 85 may also be referred to as the upper periphery 85. FIG. 4 also depicts the primary strap 89 and the primary strap 90. Additional primary straps may be placed, even though not shown. Essentially, the primary straps 88, 90 will attach at one end (proximal end) to the netting (for instance at point 92, 94) and at a second end (distal end) to the underside of the matting 52, (for instance at point 96, 98). In the most preferred embodiment, the proximal end 92, 94 are at the bottom end of the net 84. The straps may be a nylon webbing strap with buckles, which is commercially available.
As shown in FIG. 4, the mass of the mats 52 act as a weight to anchor the netting 84. Also, with the use of the primary straps 89, 90, the net 84 can be selectively tensioned. In other words, the straps can contain buckle means (not shown) that can selectively place different levels of tension, as desired by the operator. In the preferred embodiment shown in FIG. 4, the netting 84 forms a bowl with three sides. As noted earlier, one of the sides of this netting bowl is missing in order to form a window for passage of the pole vaulter. Hence, as the pole vaulter completes his (or her) jump, the pole vaulter will be held within this bowl. If the pole vaulter bounces into one of the sides of the net 84, the force will be absorbed by the net via its anchor points including the underside of the mat and at the eyelets of the curved portion of the support poles. In other words, the force created by the movement of the vaulter will be absorbed by the net since the net is securely anchored to the underside of the mat in this bowl arrangement seen in FIG. 4. It should be noted that it is also possible to have attaching means for attaching the bottom of the net to the top side of the mat. In the most preferred embodiment, the attaching means will be secondary straps, such as seen at 100, 102 attaching the bottom of net 84 to the top side of the mat 52. Additionally, it is possible to use snaps or clips for secondary straps. It is within the teachings of this invention to allow for a plurality of primary and secondary straps.
Referring now to FIG. 5, a side view of the pole vaulting device seen in FIG. 4 will now be described. This view depicts the support pole 64 and the curved portion 104 oriented in the direction of the mat 52. The distance “2L” is shown, which is basically twice the previous distance “L” due to the set back area of the support pole relative to the stretched net 84. Due to the curved portion design, if the vaulter is bouncing around the bowl net, the vaulter will not hit the support poles. Also, the support poles 66, 68 and stands 105, 106, as well as support pole 70 and stand 108 are shown. In the most preferred embodiment, all the support poles will have the curved portion. The net 84 is shown having been anchored and tensioned via the underside of the mat, as previously noted. The primary straps 120, 122 and the secondary straps 124, 126 are shown. FIG. 5 also shows the vaulter's planting box 54. The arrow “A” depicts the direction that the pole vaulter would travel. FIG. 5 also shows the mat 52a about the vaulter's planting box 54.
FIG. 6 depicts a perspective view of the pole vaulting device of the present invention. FIG. 6 depicts the support poles 56, 60, 62, 64, 66, 68, and 70, disposed within their respective stands, net 84, and mating 52, 52a. A pole 110 is in the planter's box 54, A bar 112 has been placed for the pole vaulter, as is well understood by those of ordinary skill in the art. Hence, it can be seen the three sided netting bowl section formed according to the teachings of the present invention. Thus, the force created by the weight of the vaulter against the net will be absorbed, according to the teachings of this invention. FIG. 6 further shows the cable “C” disposed about the outer periphery of the net 84.
Although this disclosure has been described and illustrated certain preferred embodiments of the invention, it is to be understood that the invention is not restricted to these particular embodiments. Rather, the invention includes all embodiments, which are functional, or mechanical embodiments of the specific embodiments and features that have been described and illustrated herein.
