[Figure 11] This diagram shows a modified version of the goal movement device. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below with reference to the attached drawings. Note that terms such as "first," "second," etc., used in the following description are merely used to distinguish similar elements, and do not limit the elements to which they are attached.

[0010] Figures 1 to 3 show a goal moving device 1 according to one embodiment of the present invention. Figure 1 is a front view of the goal moving device 1, Figure 2 is a top view of the goal moving device 1, and Figure 3 is a cross-sectional view AA of Figure 1. The goal moving device 1 according to this embodiment is used to move a competition goal 20, such as a soccer goal.

[0011] First, let's describe the goal 20 for competition. Figure 4 is a perspective view showing an example of the goal 20 for competition. As shown in Figure 4, the goal 20 for competition includes a crossbar 21 extending in the left-right direction, a pair of left and right goalposts 22, 22 extending downward from both ends of the crossbar 21, a pair of left and right side frames 23, 23 behind the pair of left and right goalposts 22, and a rear lower frame 24 extending in the left-right direction, and is constructed with a goal net (not shown) attached. The side frame 23 is formed by a lower side frame 23L extending rearward from the lower back of the goalpost 22 and an upper side frame 23U extending from the upper back of the goalpost 22 and connected to the rear end of the lower side frame 23L, and the rear lower frame 24 has both ends connected to the rear ends of the left and right lower side frames 23L.

[0012] Next, the goal moving device 1 will be described. As shown in Figures 1 to 3, the goal moving device 1 includes wheels 3, a lever member 5, and a holder 7. The goal moving device 1 is configured to hold the lower side frame 23L of the competition goal 20 with the holder 7, and by operating the lever member 5, the holder 7 and the lower side frame 23L of the competition goal 20 held therein can be lifted off the ground, allowing the competition goal 20 to be moved on the wheels 3. The following describes each component of the goal moving device 1.

[0013] The wheel 3 is rotatably mounted on a first axle member 4 that extends horizontally. In other words, the wheel 3 is rotatable around the first axle member 4. Although not particularly limited, the wheel 3 is preferably a puncture-proof tire with bearings and a diameter of about 200 to 300 mm. The first axle member 4 only needs to function as a wheel axle that rotatably supports the wheel 3, and although not particularly limited, in this embodiment, a bolt member having an outer diameter corresponding to the axle hole of the wheel 3 and a shank length greater than the width of the wheel 3 is used as the first axle member 4.

[0014] The lever member 5 is provided adjacent to the wheel 3 and is rotatably attached to the first shaft member 4 so as to be operable by an operator. Specifically, in the present embodiment, the lever member 5 has a base end portion 51 rotatably attached to the exposed portion of the first shaft member 4 exposed from the wheel 3, and is formed as a plate-like member extending from the base end portion 51 to the tip end portion 52. The tip end portion 52 of the lever member 5 is located on the outer side in the radial direction of the wheel 3, and the lever member 5 is configured such that an operator can grip a predetermined portion on the tip end portion 52 side and rotate it around the first shaft member 4 (in the direction of arrow B in FIG. 1).

[0015] FIG. 5 shows the lever member 5. As shown in FIGS. 5(a) and 5(b), in the present embodiment, a circular first through-hole 53 penetrating the lever member 5 in the thickness direction is formed in the base end portion 51 of the lever member 5. The first through-hole 53 has a diameter corresponding to the outer diameter of the first shaft member 4. Further, a connecting portion 54 to which the holding body 7 is connected is provided between the base end portion 51 and the tip end portion 52 of the lever member 5, and a circular second through-hole 55 penetrating the lever member 5 in the thickness direction is formed in the connecting portion 54. The connecting portion 54 (second through-hole 55) is located closer to the base end portion 51 (first through-hole 53) than the tip end portion 52, and the second through-hole 55 has a diameter corresponding to the outer diameter of the second shaft member8 described later. The lever member 5 is rotatably attached to the first shaft member 4 (the exposed portion thereof) through the first through-hole 53 formed in the base end portion 51.

[0016] In the present embodiment, a bolt member as the first shaft member 4 extends through the first through-hole 53 formed in the base end portion 51 of the lever member 5, inside the cylindrical first spacer 6, and the shaft hole of the wheel 3, and a nut 41 with a washer is screwed onto the tip end portion of the first shaft member 4 (see FIGS. 1 to 3). Thereby, the wheel 3 is rotatably attached to the first shaft member 4, and the lever member 5 (the base end portion 51 thereof) is rotatably attached to the first shaft member 4 (the exposed portion thereof).

[0017] The holding body 7 is configured to be able to hold the lower side frame 23L of the competition goal 20 and is rotatably connected to the connecting portion 54 of the lever member 5. Specifically, in the present embodiment, the holding body 7 includes a holding portion 71 capable of holding and releasing the holding of the lower side frame 23L of the competition goal 20, and a support portion 72 that supports the holding portion 71 and is rotatably connected to the connecting portion 54 of the lever member 5 via a second shaft member 8. In the present embodiment, as the second shaft member 8, a bolt member having a shank portion of a predetermined length is used.

[0018] FIG. 6 shows the holding body 7. As shown in FIGS. 6(a) to 6(c), in the present embodiment, the support portion 72 of the holding body 7 is formed in an L-shaped cross section and has a bottom plate portion 721 and a vertical plate portion 722 that rises from one end of the bottom plate portion 721. A circular third through hole 723 penetrating the vertical plate portion 722 in the thickness direction is formed in the vertical plate portion 722. The third through hole 723 has a diameter corresponding to the outer diameter of the second shaft member 8. Further, a stopper pin 724 of a predetermined length is provided on the outer surface of the vertical plate portion 722 facing away from the bottom plate portion 721 side. The stopper pin 724 prevents further rotation of the lever member 5 when the lever member 5 abuts against it. In the present embodiment, the rotation position of the lever member 5 that abuts against the stopper pin 724 is the initial rotation position of the lever member 5.

[0019] The holding portion 71 of the holder 7 includes a first holding member 711 and a second holding member 712. The first holding member 711 is fixed to the outer surface of the bottom plate portion 721 of the support portion 72, facing away from the vertical plate portion 722, and the second holding member 712 is connected to the first holding member 711 via a hinge 713. In this embodiment, the holding portion 71 is configured such that the second holding member 712 rotates around the hinge axis 713a, sandwiching the lower side frame 23L of the competition goal 20 between the first holding member 711 and the second holding member 712 from above and below, and in this state the second holding member 712 is fixed to the first holding member 711, thereby holding the lower side frame 23L of the competition goal 20. The holding portion 71 is also configured such that the holding of the lower side frame 23L of the competition goal 20 is released when the fixing of the second holding member 712 to the first holding member 711 is released. The second retaining member 712 can be fixed to the first retaining member 711, for example, by a bolt 9 inserted into a bolt hole 714 provided in the first retaining member 711 and the second retaining member 712, and a nut 91 screwed onto the bolt 9 (see Figure 3).

[0020] In this embodiment, the bolt member serving as the second shaft member 8 extends through a second through-hole 55 formed in the connecting portion 54 of the lever member 5, through the inside of the cylindrical second spacer 10, and through a third through-hole 723 formed in the support portion 72 of the retainer 7, and a nut 81 with a washer is screwed onto the tip of the second shaft member 8 (see Figures 1 to 3). As a result, the retainer 7, which has a retaining portion 71 capable of holding the lower side frame 23L of the competition goal 20, is rotatably connected to the connecting portion 54 located between the base end portion 51 and the tip portion 52 of the lever member 5.

[0021] Next, the operation of the goal moving device 1 will be explained with reference to Figures 7 and 8.

[0022] When moving the competition goal 20, the worker positions the goal moving device 1 adjacent to the lower side frame 23L of the competition goal 20. At this time, the goal moving device 1 is in the state shown in Figures 1 to 3. That is, in the goal moving device 1, the lever member 5 is in the initial rotation position where it abuts against the stopper pin 724 and is almost horizontal, and the holding part 71 of the holder 7 is in the holding position for holding the lower side frame 23L of the competition goal 20. The worker then rotates the second holding member 712 of the holding part 71 of the holder 7 around the hinge axis 713a to sandwich the lower side frame 23L of the competition goal 20 between the first holding member 711 and the second holding member 712 from above and below, and in that state, the second holding member 712 is fixed to the first holding member 711 using the bolt 9 and nut 91 (Figures 7(a) to (c)). As a result, the lower side frame 23L of the competition goal 20 is held by the holding part 71 of the holder 7 of the goal moving device 1.

[0023] When the lower side frame 23L of the competition goal 20 is held by the holding portion 71 of the holder 7 of the goal moving device 1, the operator grasps a predetermined part of the lever member 5 on the tip end 52 side and rotates the lever member 5 from the initial rotation position in the direction of arrow B. As a result, the holding portion 71 of the holder 7 rises from the holding position, and the lower side frame 23L of the competition goal 20 held by the holding portion 71 floats (lifts) above the ground G. The operator then rotates the lever member 5 beyond the vertical line VL passing through the axis of the first shaft member 4 to a predetermined rotation operation completion position (Figures 8(a) to (d)). Here, in the goal moving device 1, when the lever member 5 is in the initial rotation position (Figure 8(a)), the connecting portion 54 (second shaft member 8) of the lever member 5 to which the holder 7 is connected is located on one side (the left side in Figures 8(a) to (d)) with respect to the vertical line VL. On the other hand, when the lever member 5 is in the rotation end position (Figure 8(d)), the connecting portion 54 (second shaft member 8) of the lever member 5 to which the holder 7 is connected is located on the other side (right side in Figures 8(a) to (d)) with respect to the vertical line VL.

[0024] As a result, the lower side frame 23L of the competition goal 20 is lifted off the ground G and held in a lifted state, allowing the competition goal 20 to be supported by the wheels 3. In other words, the competition goal 20 can be moved using the wheels 3.

[0025] Figures 9 and 10 illustrate an example of how to move the competition goal 20 using the goal moving device 1. Figure 9 is a right side view of the competition goal 20, and Figure 10 is a left side view of the competition goal 20.

[0026] In the examples shown in Figures 9 and 10, a total of four goal moving devices 1 (1A to 1D), two on each side, are used to move the competition goal 20. Specifically, the worker holds the lower right side frame 23L of the competition goal 20 in a front view using the holders 7 of the two goal moving devices 1A and 1B (Figure 9(a)), and lifts the lower right side frame 23L of the competition goal 20 in a front view off the ground G by rotating the lever members 5 of the goal moving devices 1A and 1B from the initial rotation position to the end of the rotation operation position (Figure 9(b)). Similarly, the operator holds the lower left side frame 23L of the competition goal 20 in a front view by the holders 7 of the remaining two goal moving devices 1C and 1D (Figure 10(a)), and lifts the lower left side frame 23L of the competition goal 20 in a front view from the ground G by rotating the lever members 5 of the goal moving devices 1C and 1D from the initial rotation position to the end of the rotation operation position (Figure 10(b)). Here, in this embodiment, the goal moving devices 1A and 1B and the goal moving devices 1C and 1D are arranged in opposite directions.

[0027] As a result, the competition goal 20 is supported by the wheels 3 of the four goal moving devices 1 (1A to 1D). Therefore, multiple workers can easily move the competition goal 20 using the wheels 3 of the four goal moving devices 1 (1A to 1D) by pushing the pair of left and right goalposts 22 and / or the pair of left and right upper side frames 23U forward or backward.

[0028] Once the competition goal 20 has moved to its destination, the worker returns the lever members 5 of the four goal moving devices 1 (1A-1D) from the rotation end position to the initial rotation position. This places the lower side frame 23L of the competition goal 20 on the ground G. The worker then releases the holding bodies 7 of the four goal moving devices 1 (1A-1D) from holding the lower side frame 23L and removes the four goal moving devices 1 (1A-1D). This completes the movement of the competition goal 20.

[0029] As described above, the goal moving device 1 according to this embodiment includes a wheel 3 rotatably mounted on a first shaft member 4, a lever member 5 whose base end 51 is rotatably mounted on the first shaft member 4, and a holder 7 which has a holding portion 71 capable of holding the lower side frame 23L of the competition goal 20 and is rotatably connected to a connecting portion 54 located between the base end 51 and the tip end 52 of the lever member 5. Here, more specifically, the lever member 5 has its base end 51 rotatably mounted on the exposed portion of the first shaft member 4 that is exposed from the wheel 3, and its tip end 52 extends from the base end 51 and is located radially outward from the wheel 3. Furthermore, the holder 7, in addition to the holding portion 71, has a support portion 72 that supports the holding portion 71 and is rotatably connected to the connecting portion 54 of the lever member 5 via a second shaft member 8.

[0030] In the goal moving device 1 according to this embodiment, when the lever member 5 is in the initial rotation position, the holding portion 71 of the holder 7 is in a holding position to hold the lower side frame 23L. When the lever member 5 is rotated from the initial rotation position to the end of the rotation operation position, the holding portion 71 of the holder 7 moves from the holding position to a higher raised position, and the lower side frame 23L held by the holding portion 71 floats above the ground G, thereby enabling the competition goal 20 to be moved by the wheels 3.

[0031] Therefore, according to the goal moving device 1 of the embodiment, the competition goal 20 can be easily moved by the wheels 3. Furthermore, the goal moving device 1 of the embodiment does not have a long member like a handle in the prior art, and is a compact device overall. Therefore, according to the goal moving device 1 of the embodiment, portability and storage can be improved compared to the prior art. The first shaft member 4 corresponds to the "shaft member" of the present invention, the initial rotation position corresponds to the "first rotation position" of the present invention, and the rotation operation end position corresponds to the "second rotation position" of the present invention.

[0032] Furthermore, in the goal moving device 1 according to this embodiment, the connecting portion 54 of the lever member 5 to which the holder 7 is connected is located closer to the base end portion 51 than to the tip portion 52 of the lever member 5. In the lever member 5, the base end portion 51, which is rotatably attached to the first shaft member 4, acts as the fulcrum, the predetermined part on the tip portion 52 side that is grasped by the operator acts as the point of force application, and the connecting portion 54 acts as the point of application. Therefore, the operator can easily operate the lever member 5 to lift (raise) the lower side frame 23L of the competition goal 20 off the ground G.

[0033] Furthermore, in the goal moving device 1 according to this embodiment, the holding portion 71 of the holder 7 includes a first holding member 711 and a second holding member 712 connected to the first holding member 711 via a hinge 713, and is configured to hold the lower side frame 23L of the competition goal 20 by sandwiching it between the first holding member 711 and the second holding member 712. Therefore, the holding portion 71 of the holder 7 can hold and release the lower side frame 23L of the competition goal 20 relatively easily and reliably.

[0034] Here, although not shown in the diagram, an adjustment member may be attached to the first retaining member 711 and / or the second retaining member 712, depending on the external shape and size of the lower side frame 23L of the competition goal 20. Preferably, the adjustment member is formed in the shape of a plate from an elastic material such as rubber and is detachably attached to the inner surface of the first retaining member 711 and / or the inner surface of the second retaining member 712. When the adjustment member is attached, the retaining portion 71 of the retaining body 7 is configured to hold the lower side frame 23L of the competition goal 20 by sandwiching it between the first retaining member 711 and the second retaining member 712 via the adjustment member. In this way, regardless of the external shape and size of the lower side frame 23L of the competition goal 20, the retaining portion 71 of the retaining body 7 can stably and reliably hold the lower side frame 23L of the competition goal 20.

[0035] Furthermore, in the goal moving device 1 according to this embodiment, when the lever member 5 is in the initial rotation position, the connecting portion 54 of the lever member 5 to which the holder 7 is connected is located on one side with respect to the vertical line VL passing through the axis of the first shaft member 4, and when the lever member 5 is in the rotation end position, the connecting portion 54 of the lever member 5 is located on the other side with respect to the vertical line VL. Therefore, when the lever member 5 is rotated to the rotation end position, the lower side frame 23L of the competition goal 20 is lifted off the ground G and this state can be maintained. Thus, it is possible to move the competition goal 20 more easily.

[0036] Figure 11 shows a modified version of the goal moving device 1. In the modified version shown in Figure 11(a), the first retaining member 711 and the second retaining member 712 are formed separately, and the second retaining member 712 is fixed to the first retaining member 711 by two sets of bolts (9a, 9b) and nuts (91a, 91b). Otherwise, it is the same as the embodiment described above. In the modified version shown in Figure 11(b), only the position of the hinge 713 differs from the embodiment described above. The same effects as the embodiment described above can be obtained with these modified versions as well.

[0037] Although embodiments and variations of the present invention have been described above, the present invention is not limited to the embodiments and variations described above, and further modifications and changes are possible based on the technical concept of the present invention.
