Detailed Description
Please refer to fig. 1 and fig. 2 first. The present invention provides a wave-type jumping board, which has two lifting surface portions 10, a concave portion 20, and a supporting portion 30. The concave portion 20 is disposed between the two lifting surface portions 10, so that the wave-shaped jumping board of the present invention has a different fluctuation from the lifting surface portion 10 in addition to the fluctuation of the lifting surface portion 10, and a player in extreme sports can perform more various fancy motions during the movement of the wave-shaped jumping board of the present invention. In order to make the structure of the concave portion 20 strong, one end of the supporting portion 30 is fixed on the bottom surface of the concave portion 20, and the opposite end abuts against the ground, so as to support the concave portion 20 and the player moving on the concave portion 20. The support 30 may extend in the lengthwise direction or the widthwise direction of the wave-shaped jump plate. The concave portion 20 and the supporting portion 30 may be integrally formed, or may be combined and separated. Of course, the supporting portion 30 may not be provided in other embodiments.
Please refer to fig. 3 and fig. 4 together. Each of the raised surface portions 10 has a ground terminal 11, a high point terminal 12, and a first inclined surface 13, wherein the height of the high point terminal 12 is higher than that of the ground terminal 11, and the first inclined surface 13 is a top surface of the raised surface portion 10 and is connected between the ground terminal 11 and the high point terminal 12. In this embodiment, the first inclined surface 13 is a concave curved surface, and the slope of the first inclined surface 13 adjacent to the ground terminal 11 can approach to horizontal, so that the connection between the first inclined surface 13 and the ground surface is a smooth continuous surface. By smooth continuous surface is meant that the surface is free of corners or slits. Each lifting surface portion 10 has at least one engaging recess 14, which is located on the top surface of the high point end 12 of the lifting surface portion 10 and extends downward from the top surface. In this embodiment, each of the lifting surface portions 10 further forms at least one slot 15, and the number of the slots is equal to the number of the engaging grooves 14 of each of the lifting surface portions 10. The slot 15 is located on the side of the lifting surface portion 10 facing the other lifting surface portion 10 and extends downward from the top surface of each lifting surface portion 10, and the slot 15 communicates with one of the catching grooves 14.
In each engaging groove 14 of each lifting surface portion 10, the width of the position closer to the other lifting surface portion 10 is smaller than the width of the position farther from the other lifting surface portion 10 in the length direction of the wave-shaped jump board. Therefore, the cross-sectional shape of the engaging groove 14 may be dovetail-shaped, wedge-shaped, stepped, or the like. In this embodiment, the cross-sectional shape of the engaging groove 14 is a step shape. Specifically, each engaging groove 14 is formed with a first width space 141 and a second width space 142. The second width space 142 is distant from the grounded end 11 of the disposed lifting face portion 10 (i.e., closer to the other lifting face portion 10) than the first width space 141. In the length direction of the wave-shaped jump board, the size of the second width space 142 is larger than that of the first width space 141. In other words, the interval T1 of the first width space 141 is smaller than the interval T2 of the second width space 142, thereby enhancing the structural strength of the engaging groove 14. In the present embodiment, the second width space 142 communicates with the slot 15.
Please refer to fig. 2, fig. 5, and fig. 6. The two ends of the concave portion 20 are connection ends 201, and the two connection ends 201 are respectively connected to the high point ends 12 of the two lifting surface portions 10. The concave portion 20 has an outer shape with two ends higher and a center lower, and has a plurality of engaging protrusions 21, two extending pieces 22, and a plurality of protruding ribs 23.
The two extending pieces 22 are respectively located at the two connecting ends 201 of the concave portion 20 and protrude in the length direction of the wave-shaped jump board. The two extending pieces 22 respectively abut downwards against the high point ends 12 of the two lifting surface parts 10. The upper side surface of each extending piece 22 is a part of the top surface of the concave part 20, and the slope of the joint of the first inclined surface 13 of the lifting surface part 10 is equal, so that the joint of the lifting surface part 10 and the concave part 20 is a smooth continuous surface.
Please refer to fig. 2, fig. 3, and fig. 7. The engaging protrusions 21 are formed on the bottom surfaces of the two connecting ends 201 of the concave portion 20 and protrude downward, and one of the engaging protrusions 21 is detachably received in one of the engaging grooves 14 on the lifting surface portion 10. In the present embodiment, the cross-sectional shape of the engaging groove 14 matches the cross-sectional shape of the engaging protrusion 21 to form a tight engagement, and the engaging groove 14 and the engaging protrusion 21 do not dislocate after the engagement.
Each engaging protrusion 21 is formed with a horizontal piece 211 and a vertical piece 212. The horizontal piece 211 and the vertical piece 212 are protruded downwards from the bottom surface of the concave part 20, but the horizontal piece 211 extends in the width direction of the wave-shaped jumping board, the vertical piece 212 extends in the length direction of the wave-shaped jumping board, and the vertical piece 212 is fixedly arranged on the inner side surface of the horizontal piece 211. In other words, in the engaging protrusion 21 of one of the connecting ends 201, the longitudinal piece 212 is closer to the other connecting end 201 than the transverse piece 211, so that the engaging protrusion 21 is less prone to bending deformation toward the other connecting end 201, and the structure of the engaging protrusion 21 can be strengthened. In addition, the longitudinal fins 212 may be integrally connected to the ribs 23.
The ribs 23 are located on the lower side of the concave portion 20, and a part of the ribs 23 extends in the length direction of the wave-shaped jump board, and another part of the ribs 23 extends in the width direction of the wave-shaped jump board. In other words, the ribs 23 form a lattice structure which is staggered, so that the structural strength of the concave portion 20 in the longitudinal direction and the width direction of the jump plate can be enhanced, and the bending deformation can be avoided.
Please refer to fig. 2, fig. 8 and fig. 9. On the other hand, the female portion 20 in this embodiment may be a two-piece female portion 20, but may be a one-piece or multi-piece female portion 20 in other embodiments. Specifically, the concave portion 20 includes two extending pieces 20A, one end of each extending piece 20A is the connecting end 201, the other end opposite to the connecting end 201 is a connecting end 202, and the connecting ends 202 of the two extending pieces 20A are connected to each other. The connecting end 201 of each extension 20A is higher than the connecting end 202, thus forming a variation in elevation. Each extension member 20A has a second inclined surface 203, and the second inclined surface 203 is a top surface of the extension member 20A and is connected between the connecting end 201 and the connecting end 202. The slope of the second inclined surface 203 of each extension member 20A at the connecting end 202 can be horizontal, so that when two extension members 20A are connected, the connecting end 202 is a continuous surface.
In the concave portion 20, a part of the engaging protrusion 21 is further formed on the bottom surface of the connecting end 202 of each extending member 20A and protrudes downward. In other words, a part of the engaging protrusion 21 is formed between the two connecting ends 201 of the concave portion 20. And correspondingly, the supporting portion 30 is also formed with a fastening groove 34. The catching groove 34 of the supporting part 30 extends downward from the top surface of the supporting part 30. In the embodiment, the supporting portion 30 is formed with a slot 35 towards two side surfaces of the two lifting surface portions 10, and the slot 35 extends downwards from the top surface of the supporting portion 30 and is communicated with the engaging groove 34 of the supporting portion 30. If not otherwise specified, the technical features of the engaging grooves 34 and the slots 35 can be referred to those of the engaging grooves 14 and the slots 15.
In the present embodiment, the engaging recess 34 of one supporting portion 30 receives the engaging protrusion 21 of one connecting end 202. However, in other embodiments, the two engaging grooves 34 on the same length direction extending line of the wave-shaped jumping plate on the supporting portion 30 may be connected to form a large engaging groove, and the large engaging groove may accommodate two engaging protrusions 21 belonging to different extending members 20A.
The shape of the engaging protrusion 21 at the connecting end 202 may be similar to or different from the shape of the engaging protrusion 21 at the connecting end 201. The engaging protrusions 21 on the connecting end 202 and the connecting end 201 are similar to each other in cross-sectional shape and length, but other features may be different. If the engaging protrusions 21 on the connecting end 202 and the connecting end 201 are close, the concave portion 20 can be engaged and fixed with the engaging groove 14 of the lifting surface portion 10 via the engaging protrusion 21 on the connecting end 201, so as to form a jumping board with fluctuating height; the jump board with a higher height can be assembled by the engaging protrusion 21 at the engaging end 202 engaging with the engaging groove 14 of the lifting surface 10, and the slope can be varied. When the engaging protrusions 21 at the connecting end 202 and the connecting end 201 are different, the engaging protrusions 21 at the connecting end 202 cannot engage with the engaging grooves 14 of the lifting surface 10 and/or the engaging protrusions 21 at the connecting end 201 cannot engage with the engaging grooves 34 of the supporting portion 30.
In summary, the wave-shaped jumping board of the present invention forms a concave shape between the two lifting surface portions 10 through the concave portion 20, so that the whole board has more height variations, and the player can perform more fancy motions through different height variations. In addition, the wave-shaped jumping board is formed by combining the lifting surface part 10, the concave part 20 and the like, so that the wave-shaped jumping board can be detached and folded when not used, and the occupied volume is reduced.
