Description

[Technical Field]

[0001] The present invention relates to assistive equipment used in physical training, and more particularly to a training slider. [Background technology]

[0002] As an assistive device used during training, a flat slider that moves freely on the floor in a predetermined direction is known. For example, Patent Document 1 describes a slider that has grips 500 on both sides and a top plate (board body 101). Patent Document 2 also describes a slider that has wheels on a running frame (2) so that a bar (5) can be gripped. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3221280 [Patent Document 2] Microfilm of the contents of the specification and drawings attached to the application of Utility Model Application No. 63-160583 (Utility Model Application No. 2-79970) Summary of the Invention [Problem to be solved by the invention]

[0004] During training, in order to effectively apply stress to the target body part and prevent physical injury, it is important to train with correct posture and to avoid generating unnecessary force. Assistive devices used during training are expected to guide trainees into correct posture, make it easier to maintain posture during training, and support the trainee in preventing unnecessary force from being generated when maintaining posture.

[0005] The abdominal exercises described in the above-mentioned patent documents, which use sliders and grips or bars to support the body while lying face down on the floor, have the problem that the upper body must be supported only by the palms of the hands, making it difficult for some trainees to maintain the posture without exerting unnecessary force.Furthermore, it is difficult to adjust the load according to the progress of the training or to accommodate a variety of exercises other than just abdominal muscle training, which makes the exercise monotonous.

[0006] The present invention has been made in consideration of the above circumstances, and its purpose is to provide a training slider that makes it easy to maintain posture during training, allows for easy load adjustment, and can be used for a variety of exercises. [Means for solving the problem]

[0007] The invention disclosed in this application to solve the above problems has various aspects, and representative aspects thereof are outlined below.

[0008] (1) A training slider comprising: a top plate having at least four wheels fixed to roll in a sliding direction; a flat surface arranged in an area surrounded by the wheels and having an area sufficient to support at least the palms of both hands; a groove arranged on one side of the flat surface in the sliding direction and extending in a direction perpendicular to the sliding direction; and a bar arranged on the one side of the groove in the sliding direction at a distance from the top plate and extending in a direction perpendicular to the sliding direction.

[0009] (2) In (1), the training slider, wherein the groove has a V-shaped cross section.

[0010] (3) In (1), the flat surface and the upper surface of the groove are smoothly connected.

[Figure 3] FIG. 10 is a diagram showing an example of how the training slider is used. [Figure 4] FIG. 10 is a diagram showing another example of how the training slider is used. DETAILED DESCRIPTION OF THE INVENTION

[0014] FIG. 1 is a perspective view showing the appearance of a training slider 1 according to a preferred embodiment of the present invention.

[0015] The training slider 1 is a low, flat rectangular plate with wheels 2 attached to its four corners, allowing it to slide freely on the floor in the direction indicated by the arrow D in the figure. Hereinafter, this direction will be referred to as the sliding direction D.

[0016] In this embodiment, the training slider 1 is composed of a pair of side panels 3 extending in the sliding direction D, wheels 2 fixed near both ends of each side panel 3 so as to roll in the sliding direction D, a top panel 4 fixed across the pair of side panels 3, and a bar 5 fixed across the pair of side panels 3 and extending in a direction perpendicular to the sliding direction D.

[0017] All of the wheels 2 are fixed so that they can roll in the sliding direction D, and therefore the training slider 1 placed on the floor surface can slide freely only in the sliding direction D, and movement in other directions is restricted. In addition, although the number of wheels 2 is four in this example, this number may be increased to, for example, six or eight. However, since the side panels 3, top panel 4, and bar 5 of the training slider 1 usually have sufficient rigidity to resist deformation due to the load during training, it is usually not necessary to increase the number of wheels 2. The wheels 2 can be fixed to the side panels by any method, and in the example shown, they are bolted.

[0018] The side panels 3, top panel 4, and bar 5 are formed from a material that is sufficiently rigid to resist deformation due to the load during training, and may be made from any material, such as steel, aluminum alloy, or other metal, hard synthetic resin or FRP (fiber-reinforced plastic), or wood. In this example, the side panels 3, top panel 4, and bar 5 are made from steel, and are each fixed by welding and painted for surface protection. If the side panels 3, top panel 4, and bar 5 are made from a material other than metal, they may be fixed to each other by adhesive or screws. Furthermore, the materials of the side panels 3, top panel 4, and bar 5 do not necessarily have to be the same; they may all or partly be made from different materials.

[0019] The top plate 4 has a flat surface 6 that is provided at the same height as the upper surface of the side plate 3, and a groove 7 that is located on one side of the flat surface 6 in the sliding direction D, which in this case is the far right side in the figure. The groove 7 has a V-shaped vertical cross section and extends in a direction perpendicular to the sliding direction D. The portion that forms the flat surface 6 of the top plate 4 and the portion that forms the groove 7 may be formed as an integrated member, or may be made as separate members and then fixed to the side plate 3 to form the top plate 4. In the former case, the portion that forms the flat surface 6 and the portion that forms the groove 7 may be formed in advance by bending the steel plate that will form the top plate 4, and then the steel plate may be welded to the side plate 3. In the latter case, the flat plate that forms the flat surface 6 and the V-shaped steel member that forms the groove 7 may be welded to the side plate 3, respectively.

[0020] The flat surface 6 has an area large enough to support at least the palms of the trainee. That is, the trainee can assume a posture in which both palms are placed on the flat surface 6 to support their upper body. The weave 8 between the flat surface 6 and the upper surface of the grooves 7 may have a slight gap or a bent shape, but is preferably smoothly connected. The reason for this is to prevent the trainee's fingers from getting caught in the weave 8 or from feeling pain when they place their palms on the flat surface 6 and hook their fingers into the grooves 7 to firmly hold the training slider 1, as will be described later. However, even if there is a gap in the weave 8, as long as it is sufficiently small, it will not hinder the use of the training slider 1.

[0021] Furthermore, the edge 9 on the other side of the flat surface 6 in the sliding direction D, which is the left front side in this figure, is bent downward, forming a bent portion 10 that hangs down. If the edge 9 were simply the cut surface of a steel plate, the trainee's wrist or the like might feel pain when it comes into contact with the edge 9 during training, so this is to prevent this and to improve the rigidity of the flat surface 6.

[0022] The bar 5 may be a hollow round bar. The cross-sectional shape of the bar 5 does not necessarily have to be circular, and it may also be solid, but a circular cross-section is preferable because it is preferable that there are no sharp edges when the trainee comes into contact with it during training, and a hollow material is preferable in order to reduce the overall weight of the training slider 1.

[0023] 2 is a top view of the training slider 1. In the figure, the area R surrounded by the wheels 2 is indicated by a dashed line. This area R is obtained by connecting the centers of the contact surfaces of the four outermost wheels 2 that support the training slider 1 and the four wheels 2 that contact the floor. In this example, since there are four wheels 2, the area R is a rectangle obtained by connecting the centers of the contact surfaces of each wheel 2 that contact the floor.

[0024] As shown in the figure, the flat surface 6 of the tabletop 4 is located in area R. That is, at least the area of ​​the flat surface 6 where the trainee's palms are placed is included in area R. This is because if the flat surface 6 were to extend outside area R and the trainee were to put their weight on the flat surface 6 outside area R, there is a risk that the training slider 1 would lift off the floor and tip over.

[0025] 3 is a diagram showing an example of how to use the training slider 1. The diagram shows a side view of a trainee P performing abdominal exercises on the floor using the training slider 1, with the side panel 4 of the training slider 1 partially cut away for illustration purposes.

[0026] In the training shown in the figure, trainee P kneels on the floor and supports the weight of his or her upper body with the palms of both hands on the flat surface 6 of the training slider 1, while hooking his or her fingers into the grooves 7, thereby firmly and stably holding the training slider 1. Therefore, when trainee P trains in this position, his or her upper body can be stably supported whether or not he or she stretches his or her body to slide the training slider 1 backward or contracts his or her body to pull the training slider 1 back, so that posture is maintained firmly and unnecessary force is not generated, which is expected to enable effective training.

[0027] Although this training is effective enough when the training slider 1 is left in a free state, the training load can be easily adjusted by fixing the bar 5 with an elastic body such as a rubber tube 11 and applying a repulsive force when the training slider 1 is pulled back toward the user.

[0028] In the illustrated example, the trainee P has his fingers hooked into the grooves 7, but he can also hold the training slider 1 by positioning his palm further back and gripping the bar 5 tightly.

[0029] 4 is a diagram showing another example of how to use the training slider 1. The diagram shows a front view of a trainee P using the training slider 1 to perform lower limb exercises on the floor, with the side panel 4 of the training slider 1 partially cut away for illustrative purposes.

[0030] In the training shown in the figure, trainee P stands on the floor and slides the foot he or she wants to train (the left foot in the figure) sideways into the groove 7 of the training slider 1 placed on the floor. While in this position, he or she squats while keeping the torso in position and extends the left leg, pushing the training slider 1 away (as shown in the figure). Then, while standing up, he or she shortens the left leg, pulling the training slider 1 closer. This exercise effectively trains the thigh muscles, such as the femoral muscles and hamstrings, as well as the gluteal muscles. Furthermore, because the foot placed on the training slider 1 is caught in the V-shaped groove 7 during training, it prevents accidents such as the training slider 1 coming off the foot and causing a fall, and allows the trainee to maintain a firm posture during training. Furthermore, training with the foot placed in the V-shaped groove 7 allows the trainee to be aware of the vector of force applied to the ground when pushing off, which supports more efficient movement learning.

[0031] The training shown in Figures 3 and 4 is one example of training using the training slider 1. In addition to this, a variety of floor-based training is possible by placing the palms or forearms on the flat surface 6 or hooking the toes of one or both feet in the grooves 7, and this compact unit can effectively train various parts of the body.
