Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when a user performs an exercise to improve muscle strength by applying a load to his / her own muscles using the above-described exercise assisting tool for training, it is difficult to concentrate the load on a specific part that he / she wants to improve preferentially.

Means for Solving the Problems

[0005] The exercise equipment that solves the above problems is an exercise device that allows the user to perform exercises in a hanging position while gripping the handles. The exercise equipment comprises a rotating shaft, an insertion part connected to the rotating shaft, and a receiving part into which the insertion part can be inserted. The handles rotate in conjunction with the rotational movement of the rotating shaft, and the receiving part has a plurality of holding parts located along the circumferential direction of the rotating shaft. In a first state, when the insertion part is not inserted into the holding parts, the angle of the handles can be varied to any angle in the circumferential direction of the rotating shaft, and in a second state, when the insertion part is inserted into the holding parts, the angle of the handles can be fixed to any angle in the rotational direction of the rotating shaft.

[0006] According to this configuration, the user can change and fix the angle of the grip to any desired angle by manipulating the grip. This allows the user to change the angle of the grip to match the body part they want to apply load to, and by fixing the angle of the grip in that position and exercising, they can concentrate the load on the desired body part.

[0008] Below, one embodiment of the exercise equipment will be described with reference to Figures 1 to 7. <Overall composition of exercise equipment> As shown in Figure 1, the exercise equipment 1 is erected on the floor and has a pair of left and right legs 15 positioned on the floor. A support column 16 is provided between the two legs 15. The support column 16 maintains the distance between the legs 15 to ensure the stability of the exercise equipment 1. A pair of left and right support columns 14 are erected vertically from the pair of left and right legs 15. Between the two support columns 14, at the upper ends of both support columns 14, is a chin-up bar 10 to which a pair of left and right grips 20 are attached. Footrests 14a are provided on both support columns 14, extending horizontally in the depth direction of the exercise equipment 1. The footrests 14a allow the user to rest their feet when gripping the grips 20. By providing the footrests 14a, the user can easily transition to a hanging position while gripping the grips 20. Exercises performed in this hanging position include pull-ups. In this specification, the vertical, horizontal, and depth directions refer to directions relative to the state in which the exercise equipment 1 is placed on the floor, as shown in Figure 1.

[0009] <Chinning bar> As shown in Figure 2, the chin-up bar 10 comprises a bar body 11 and a shaft 12. The bar body 11 comprises a main body portion 11a made of a hollow square timber and plate-shaped side portions 11b attached to the left and right sides of the main body portion 11a. The shaft 12 is attached to the pair of side portions 11b. The main body portion 11a has a plate-shaped central portion 11c attached to its center in the left-right direction, through which the shaft 12 passes. The central portion 11c receives the load applied to the elongated shaft 12. The main body portion 11a has two insertion portions 11d. Each insertion portion 11d is a comb-shaped hole drilled on the surface visible from the depth direction when the exercise equipment 1 is installed. Each insertion portion 11d is provided in a symmetrical position with respect to the central portion 11c. Each insertion portion 11d has the same configuration.

[0010] Each insertion portion 11d includes a first insertion portion 111 extending in the left-right direction, which is the extension direction of the shaft 12, and a plurality of second insertion portions 112 projecting upward in a direction perpendicular to the extension direction of the first insertion portion 111. The first insertion portion 111 and the second insertion portions 112 are integrally formed, and the insertion portion 23b of the grip 20, which will be described later, can be inserted into it, and the insertion portion 23b is movable between the first insertion portion 111 and the second insertion portions 112. In this embodiment, each insertion portion 11d has nine second insertion portions 112 provided at predetermined intervals in the left-right direction, which is the extension direction of the first insertion portion 111.

[0011] <Grip installation> As shown in Figures 1 and 2, the grips 20 are provided one on each side of the central part 11c of the chin-up bar 10. As shown in Figures 2 and 3, the grip 20 comprises a gripping portion 21 that serves as the user's grip, a grip body portion 22 located above the gripping portion 21, and a connecting portion 23 that is joined to the grip body portion 22 and connected to the chin-up bar 10. The detailed configuration of the gripping portion 21 and the grip body portion 22 will be described later.

[0012] The connecting portion 23 comprises a sliding member 23a and an insertion portion 23b. The sliding member 23a has a configuration in which a linear ball bearing that assists linear motion is housed in a cylindrical case. The shaft 12 is inserted through the sliding member 23a. The sliding member 23a is slidable in the left-right direction, which is the direction in which the shaft 12 extends. The insertion portion 23b is a rod-shaped member. The insertion portion 23b is connected to the sliding member 23a and is provided protruding from the outer circumferential surface of the sliding member 23a so that the radial direction and depth direction of the sliding member 23a coincide.

[0013] With the shaft 12 inserted through the sliding member 23a, the insertion portion 23b is inserted into the insertion portion 11d. In this state, each grip 20 is attached to the chin-up bar 10 and is movable in the left-right direction between the side portion 11b and the central portion 11c of the chin-up bar 10 in conjunction with the sliding member 23a. Figure 3 shows the insertion portion 23b inserted into the second insertion portion 112 of the insertion portion 11d. In this state, the insertion portion 23b is locked to the second insertion portion 112, restricting the left-right movement of the sliding member 23a. On the other hand, Figure 4 shows the grip 20 rotated around the axis of the shaft 12 as if being pulled up in the depth direction. In this state, the locking of the insertion portion 23b in the second insertion portion 112 is released, and the insertion portion 23b is positioned in the first insertion portion 111. This allows the sliding member 23a to move in the left-right direction.

[0014] <Grip configuration> As shown in Figure 5, the grip 20 comprises a gripping portion 21, a grip body portion 22, and a connecting portion 23. The grip body portion 22 comprises a rotating shaft 30, a fitting portion 40, and a fitted portion 50. The rotating shaft 30 is provided to extend in the vertical direction. The fitting portion 40 is a shaft located at the top of the rotating shaft 30 and penetrates the rotating shaft 30 along its radial direction. In other words, both ends of the fitting portion 40 and a part of the shaft connected thereto protrude from the outer circumferential surface of the rotating shaft 30.

[0015] The insertion portion 50 comprises a main body 51, a substantially cylindrical case 52 that houses the main body 51, and a bottom plate 53 that forms the circular bottom surface of the case 52. The main body 51 is a substantially cylindrical member through which the portion of the rotating shaft 30 below the insertion portion 40 can be inserted. The rotating shaft 30 inserted into the insertion portion 40 is capable of rotational movement and vertical movement within the insertion portion 40.

[0016] The main body 51 includes a holding portion 60. The holding portion 60 is composed of twelve convex portions 61 and twelve concave portions 62 that protrude from the upper end portion of the main body 51. The convex portions 61 and the concave portions 62 are alternately and continuously arranged along the circumferential direction of the main body 51. The sizes of each of the convex portions 61 and the concave portions 62 are equal. The holding portion 60 is configured to be able to accommodate the insertion portion 40. According to the arrangement of the convex portions 61 and the concave portions 62 as described above, the insertion portion 40 can be accommodated in the concave portion 62 at a position where the rotation axis 30 rotates approximately 30 degrees. That is, the insertion portion 40 can be inserted into the inserted portion 50. In addition, in a state where the main body 51 is accommodated in the case 52, the upper opening end of the case 52 and the upper ends of each of the convex portions 61 of the holding portion 60 are at the same position in the vertical direction.

[0017] The gripping portion 21 includes a rod-shaped gripping member 21a that a user grips and a U-shaped support member 21b that supports both ends of the gripping member 21a. The gripping member 21a and the support member 21b are, for example, fastened and fixed. The rotation axis 30 inserted through the main body 51 of the inserted portion 50 has its lower end fixed to the upper central portion of the support member 21b. The rotation axis 30 and the support member 21b are fixed by pressing, such as by press-fitting, a reduced-diameter portion provided at the lower end of the rotation axis 30 into a hole provided in the support member 21b. The gripping portion 21 integrated with the rotation axis 30 performs a rotation operation in conjunction with the rotation operation of the rotation axis 30.

[0018] <Action regarding the rotation angle adjustment of the grip> [[ID=,10]]As shown in FIGS. 6(a) to (c), the grip 20 can change the angle of the gripping portion 21. The angle of the gripping portion 21 is the angle when rotating about the axis of the rotation axis 30 along the vertical direction as the rotation center.

[0019] In Fig. 6(a), the gripping portion 21 is lifted upward in the direction away from the floor. When the gripping portion 21 is lifted, the rotating shaft 30 is also lifted. When the rotating shaft 30 is lifted, the insertion portion 40 is also lifted. When the insertion portion 40 is lifted, the insertion portion 40 moves in a direction relatively separating from the inserted portion 50. As a result, the insertion portion 40 is in a state of not being accommodated in the recess 62. That is, the insertion portion 40 is in a first state of not being inserted into the inserted portion 50. In the first state, the rotating shaft 30 is rotatable because the insertion portion 40 is not caught by the convex portion 61 in the rotation direction of the rotating shaft 30. Therefore, the gripping portion 21 is in a rotatable state in conjunction with the rotation operation of the rotating shaft 30. That is, the rotation of the gripping portion 21 is allowed.

[0020] Fig. 6(b) shows a state where the gripping portion 21 is rotated 90 degrees when the gripping portion 21 is in the first state. The rotation of the gripping portion 21 can be performed by a user who holds the gripping member 21a. Then, as shown in Fig. 6(c), when the gripping portion 21 is moved downward in the direction approaching the floor, the insertion portion 40 moves downward as the rotating shaft 30 also moves downward. When the insertion portion 40 moves downward, the insertion portion 40 moves in a direction relatively approaching the inserted portion 50. As a result, the insertion portion 40 is accommodated in the recess 62 at a position rotated 90 degrees from the position in Fig. 6(a). That is, the insertion portion 40 is in a second state of being inserted into the inserted portion 50. In the second state, the rotation of the gripping portion 21 is restricted. In the second state, the rotating shaft 30 cannot rotate because the insertion portion 40 is caught by the convex portion 61 in the rotation direction of the rotating shaft 30. Note that the angle adjustment of the left and right grips 20 can be performed independently. For this reason, the left and right grips 20 can be arranged at different angles.

[0021] <Function regarding alignment of the grips in the left - right direction> As shown in Figures 7(a) to 7(c), the grip 20 can change the left-right position of the gripping portion 21. In Figure 7(a), the gripping portion 21 is lifted towards the front in the depth direction. When the gripping portion 21 is lifted towards the front, the sliding member 23a rotates around the shaft 12. As the sliding member 23a rotates, the insertion portion 23b also rotates. As the insertion portion 23b rotates, it enters a third state in which it is inserted from the second insertion portion 112 into the first insertion portion 111. In the third state, the position of the insertion portion 23b becomes variable in the left-right direction while it is inserted into the first insertion portion 111. Therefore, the gripping portion 21 becomes variable in position between both ends of the shaft 12. In other words, movement of the gripping portion 21 is permitted.

[0022] Figure 7(b) shows the gripping portion 21 in the third state, moved from, for example, the position marked "1" in the figure to a position between the positions marked "5" and "7". The movement of the gripping portion 21 can be performed by the user holding the gripping member 21a. Then, as shown in Figure 7(c), when the gripping portion 21 is stopped from being lifted towards the user and moved toward the user, the insertion portion 23b enters the fourth state, inserted into the second insertion portion 112. In the fourth state, the insertion portion 23b is locked to the second insertion portion 112, so the gripping portion 21 becomes immobile in the left-right direction while inserted into the second insertion portion 112. Therefore, the gripping portion 21 can be fixed in a position between both ends of the shaft 12. In other words, the movement of the gripping portion 21 is restricted. Note that the left-right position adjustment of each grip 20 can be performed independently. Therefore, each grip 20 can be positioned in a different location. Furthermore, the angle and position of the grips 20 can be adjusted at any time. In other words, one can be adjusted after the other, or only one or only the other can be adjusted.

[0023] <Effects of the Embodiment> (1) The user can change and fix the angle of the grip 20 to any desired angle by manipulating the grip 20. This allows the user to change the angle of the grip 20 to match the part of the body they want to apply load to, and by fixing the angle of the grip 20 in that position and performing exercises in a hanging position, they can apply load intensively to the desired part of the body.

[0024] (2) The user can change and fix the angle of the grip 20 to any angle simply by moving the grip 20 away from the floor or towards the floor. This operation of changing and fixing is simple and can be done quickly. In other words, the configuration of this embodiment is simpler and faster than when the angle of the grip 20 is fixed separately with screws or bolts.

[0025] (3) The user can change the position of the grip 20 by moving it left or right. This allows the user to concentrate the load on a desired area, as described in (1) above. Furthermore, the left or right movement of the grip 20 can accommodate physical characteristics, such as having wide or narrow shoulders.

[0026] <Example of changes> The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0027] Although both ends of the insertion portion 40 are provided to protrude from the rotating shaft 30, it is also acceptable for only one end to protrude. The main body 51 and the case 52 are cylindrical members, but it is sufficient that the main body 51 can be housed inside the case 52; for example, the case 52 may be a rectangular tube.

[0028] Although a case 52 is provided, the main body 51 and the connecting part 23 may be directly connected without the case 52. Although a bottom plate 53 is provided, it is not necessary to provide the bottom plate 53 if the main body 51 is housed and fixed inside the case 52.

[0029] Alternatively, the rotating shaft 30 may be a simple shaft that does not rotate, and the fitted portion 50 through which the shaft is inserted may rotate. The shape of the protrusion 61 and recess 62 is sufficient as long as the insertion portion 40 can be inserted into them. Alternatively, the protrusion 61 and recess 62 may be formed directly on the upper open end of the case 52.

[0030] The exercise equipment 1 may consist only of the configuration of the grip 20 in the embodiment. That is, the exercise equipment 1 may not have a configuration for moving the grip 20 in the left-right direction, and the left-right position of the grip 20 may be fixed. Conversely, the exercise equipment 1 may consist only of a configuration for moving the grip 20 in the left-right direction, and the grip 20 may be fixed in position without rotating.

[0031] The grip 20 may be configured to be adjustable to at least two angles, for example, 90 degrees, and the variations in the adjustable angles can be arbitrarily changed by how the convex portion 61 and the concave portion 62 are formed.

[0032] The grip 20 only needs to be movable to at least two positions in the left-right direction. The number of adjustable positions and the range between them can be arbitrarily changed depending on how the second insertion part 112 is formed relative to the first insertion part 111.

[0033] The exercise equipment may be configured with a single vertically erected support column and the chin-up bar 10 of the embodiment positioned on that support column. The chin-up bar 10 may be directly attached to the single vertically erected support column. Alternatively, the chin-up bar 10 may be attached to a rod-shaped member that branches in the front-to-back direction from the single vertically erected support column.

[0034] The support columns 14 and the chin-up bar 10 may be fixed by being sandwiched between the floor surface and the ceiling surface opposite the floor surface. In this case, the number of support columns may not be two, but for example, one.

[0035] The insertion portion 11d may be a single insertion portion 11d without being divided into left and right sections. Two grips 20 may be placed on this single insertion portion 11d. The sliding member 23a may be a roller bearing or a needle bearing.

[0036] • Exercise equipment 1 can also be used as exercise equipment 1 for simply hanging. [Note] The technical concepts that can be understood from the above embodiments and alternative examples are described below.

[0037] (i) An exercise device that allows a user to perform exercises in a hanging position while gripping a grip, comprising a chin-up bar and the grip provided on the chin-up bar, wherein the chin-up bar includes a chin-up bar body and a shaft connected to the chin-up bar body and extending in the left-right direction, the grip includes a sliding member through which the shaft can be inserted and which is slidable in the direction of extension of the shaft, and an insertion part connected to the sliding member and which is slidable in accordance with the movement of the sliding member, the chin-up bar body includes an insertion part into which the insertion part can be inserted, and the insertion part is the same The shaft includes a first insertion portion extending along the extension direction of the shaft and a plurality of second insertion portions integrally formed with the first insertion portion, wherein the plurality of second insertion portions protrude in a direction perpendicular to the extension direction of the first insertion portion and are positioned at predetermined intervals in the extension direction of the first insertion portion, and when the insertion portion is inserted into the first insertion portion, the grip can be moved to any position between the ends of the shaft, and when the insertion portion is inserted into any of the second insertion portions, the grip can be fixed to any position between the ends of the shaft.

[0038] Because each user has different physical characteristics, for example, the training exercise aid disclosed in Patent Document 1 had to be designed assuming the average physique of the user, making it difficult to perform training tailored to the user's physique. In contrast, according to the above appendix (a), the user can apply load to a desired muscle group by changing the position of the grip in the left-right direction, and by fixing the position of the grip in the left-right direction, the user can apply load to that area intensively according to their physical characteristics.
