Practijumps

The features of the present invention will be more readily understood when the following detailed description is considered in conjunction with the accompanying drawings wherein like characters represent like parts throughout the several views and in which:

FIG. 1 shows a front view of a high jump according to the present invention.

FIG. 2 shows a side view of the high jump.

FIG. 3 shows a perspective view of pieces of vinyl sliding connected together in the manner used by the present invention.

FIG. 4 shows an exploded view of parts of a broad jump according to the present invention.

FIGS. 5, 6, 7, and 8 show front views of different size broad jumps.

FIGS. 9, 10, 11, and 12 show side views corresponding respectively to the broad jumps of FIGS. 5, 6, 7, and 8.

FIG. 13 shows a perspective exploded view of parts of a bar jump according to the present invention.

The high jump 10 according to the present invention includes a frame 12 and will now be discussed with references to FIGS. 1, 2, 3, and 13. It should be noted that FIG. 13 shows an exploded view of a bar jump 210 using an identical frame 12 as used with the high jump 10.

The frame 12, which is best shown in FIG. 13, has right and left bases 14R and 14L. Each of the bases includes front and back base members 16F and 16B respectively. Each of the front base members 16F is connected to a coresponding back base member 16B by a tee 18R or 18L. The tees 18R and 18L are glued to the corresponding base members. Each of the base members has a corresponding end cap 20 which is glued to it.

Right and left nipples 22R and 22L extend below corresponding tees 24R and 24L and allow these tees to be respectively connected to the corresponding tees 18R and 18L. Extending between the tees 24R and 24L is a cross-brace 26. Mounted in each of the tees 24R and 24L is a corresponding upright 28R or 28L, each of which has a corresponding cap 30R or 30L glued as its top.

Each of the tubular members of the frame 12 (28R, 28L, 26, 16F, and 16B) is made of white PVC pipe, preferably 11/2" PR160 and Schedule 40 pipe. Although the frame material is quite light in weight, the frame 12 provides for added stability in that the cross-brace 26 and right and left bases 14R and 14L are hollow and can be filled with water or sand to increase the stability of the jump 10 or 210. As shown in FIGS. 1, 2, and 13, the cross-brace 26 extends at a higher vertical position that the bases 14R and 14L.

The uprights 28R and 28L include a series of mount holes 32 which are drilled therein and which may be used to accommodate a bolt such as bolts 234 in FIG. 13 which are used to support the bar 236 upon the uprights. The mount holes serve as a plurality of mounts. The bar 236 is made from square white vinyl downspout material and includes outdoor black tape at 2" intervals. The tape is 2" wide and provides a bar 236 having alternating 2" white and black stripes.

Although not shown, the uprights 28R and 28L may include numbers above each of the holes 32 corresponding to the height of the high jump, these numbers starting with 10". Numbering for the bar jump may begin at 12" (this numbering also not being shown) in order to incorporate the 2" thickness of the bar 236 into the measurement.

The mounting of boards upon the frame 12 to realize the high jump 10 will now be discussed with reference to FIGS. 1, 2, and 3. Advantageously, the present invention uses standard vinyl siding to provide the boards for the high jump (as well as for the broad jump discussed below). The vinyl siding, which is usually sold in 12' boards, may be cut into 4' lengths. FIG. 3 shows a perspective view of 2 pieces of vinyl siding 36. The vinyl siding may come flat or may be a double type of siding (includes a fold in the middle of the siding as shown). The lower of the siding pieces 36 includes an upper securing means 38U which is disposed outside of a bottom securing means 38B. As will be appreciated from the drawings, each of the securing means 38U and 38B are lock strips which mate to a complementary lock strip. Although not shown in FIG. 3, each of the pieces of vinyl siding 36 would be modified before use with the present invention by removal of the nailing strips 40 and, additionally, rounding of any sharp edges.

After the nailing strips 40 are removed from a plurality of pieces of house siding 36, one of the pieces 36 may be converted into a top board by placement of a 1/2" diameter PVC brace-pipe 42 (FIGS. 1 and 2) along the upper edge of the top board 44. The brace 42, which is preferably Schedule 40 PVC, is drilled and bolted to the top board 44. As will be readily appreciated, such bolts may extend into the holes 32 (labeled in FIG. 13 only). As best shown in FIG. 2, lower boards 46 may simply hang from the immediately above board by having the upper securing means 38U secure the board to the bottom securing means 38B (securing means best shown in FIG. 3). As best shown in FIG. 1, a bottom board 48 may have a different height and width from the boards 46 in order to allow it to fill the space below the bottom edge of the lowest of boards 46. The board 48 additionally has the shown smaller width so that it may fit within the bases 14R and 14L (bases labeled in FIG. 13 only). In the preferred embodiment, the boards 44 and three boards 46 would each be 8" in height, whereas two board 48, one 6" in height and the other 4" in height would be included. The use of the alternate boards 48 would allow one to accommodate different heights, as the holes 32 are preferably spaced at 2" intervals.

As shown in FIG. 2 only, a jump stick 50 may be rested on top of top board 44. The jump stick is preferably a pipe of 1" PVC cut to 49" long and capped at both ends. The jump stick 50 would also be striped in the same manner as the bar 236.

The high jump 10 of the present invention is highly advantageous in that the high jump is constructed by securing the top board 44 at the appropriate level of the uprights 28R and 28L. The rest of the boards (46 and 48) are then hung from the immediately preceding board to fill in the "air space" to the ground. For training purposes, one may place the jumping stick 50 as shown in FIG. 2 to provide the illusion of a bar jump. The bottom boards (46 and 48) can then gradually be removed until the bar 50 is all that remains to jump. Since the present invention is preferably sold in an assembly including both the high jump 10 and the bar jump 210, the use of identically constructed frames 12 for both the high jump and the bar jump allows one to convert easily to two bar jumps or two high jumps.

Note that the top board 44 and the high bar 236 each serve as jump members respectively in the high jump 10 and the bar jump 210.

With reference now to FIGS. 4 and 9, a broad jump 110A will now be discussed. Each of the components of the broad jump 110A will be labeled in the 100 series with the same last two digits as the corresponding component, if any, of the high jump 10. Additionally, the construction details of the smaller broad jumps 110B, 110C, and 110D will be readily appreciated by considering FIGS. 6-8 and 10-12.

The broad jump 110A includes a back cross-brace 126A extending between right and left uprights 128R and 128L. Elbow type fittings 124R and 124L are glued or connected by 1/2" aluminum sheet metal screws in order to secure them to the PVC pipe pieces used for cross-brace 126A an uprights 128R and 128L. In similar fashion, fittings 118R and 118L may be connected to bases 114R and 114L. A front cross-brace 160A extends between front uprights 162RA and 162LA. Fittings like those used for 124R and 124L may be used as shown to connect the front cross-brace 160A, front uprights or post portions 162RA and 162LA, and bases 114R and 114L. The structural members of the frame 112A are constructed of PVC pipe and may be filled with water or sand to stabilize the jump 110A.

A small amount of material may be removed from some of the fittings (such as 124R and 124L) and may be slid over to use as a shim (not shown) below the center of broad jump board 144. The board is attached to the frame 112A by aluminum sheet metal screws extending into holes at the corners of the frame. Advantageously, the board 144 is a piece of house siding, preferably vinyl, as used for boards 44 and 46 of the high jump. As shown, the board 144 has a major planar surface (i.e., its top surface) which extends at least partly in a horizontal direction.

The broad jumps 110B, 110C, and 110D are constructed in similar fashion to broad jump 110A. Jump 110B simply differs in dimensions from broad jump 110A. Broad jump 110C uses 45.degree. elbows 164 (only one visible in FIG. 11) such that the front post portions 162LC (and corresponding right post portion not visible) extend at a 45.degree. angle to vertical. The broad jump 110D does not include any front post portions. Instead, front cross-brace 160D extends directly between the fronts of the bases as best shown in FIG. 8.

Because of the differences in lengths of the various board jumps shown in FIGS. 5-8, the broad jumps may be easily stored and stacked together. As with the pieces of house siding used for the high jump, the pieces of house siding used for the board jumps have the nailing strips and sharp edges removed.

It should also be noted that the present jumps may be readily dismantled and placed in a zippered nylon tent pull bag.

It should be emphasized that the present invention is highly advantageous by way of its construction from common materials that provide durability, minimum upkeep, and reduced cost. Because all of the materials may be purchased at most local hardware stores or building supply centers, the present set of jumping devices do not require special manufacturing processes. This results in substantial savings in manufacturing costs.

Although various specific embodiments have been described herein, it is to be understood that these are for illustrative purposes only. Various modifications and adaptations will be apparent to those of skill in the art. Accordingly, the scope of the present invention should be determined by reference to the claims appended hereto.
