[Figure 5] 4 is a schematic diagram showing another schematic configuration of a training machine to which the support device according to the first embodiment of the present invention is attached. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] [First embodiment] 1 is a schematic diagram showing the general configuration of a training tool to which a support device according to a first embodiment of the present invention has been attached. The training tool 100 is used for exercise or rehabilitation aimed at strengthening muscles. Hereinafter, the up-down direction, left-right direction, and front-rear direction will be defined as shown in FIG. 1.

[0009] The training device 100 shown in FIG. 1 employs a weight stack system and includes a frame 101, a cable 102, a pulley group 103, a weight stack 104, a lift shaft 105-1, a left guide shaft 105-2, and a right guide shaft 105-3.

[0010] The frame 101 is a skeleton that supports the weight stack 104. The frame 101 shown in FIG. 1 includes a right frame 101-1, an upper frame 101-2, a left frame 101-3, and a lower frame 101-4. The right frame 101-1 and the left frame 101-3 are pillars that extend in the vertical direction. The upper frame 101-2 connects the upper end of the right frame 101-1 to the upper end of the left frame 101-3. The lower frame 101-4 connects the lower end of the right frame 101-1 to the lower end of the left frame 101-3.

[0011] One end 102a of cable 102 is located outside frame 101 of training device 100. A user of training device 100 (hereinafter simply referred to as the user) connects an attachment to one end 102a of cable 102 according to the training to be performed. The other end 102b of cable 102 is fixed to upper frame 101-2. For example, by connecting a handle to be held by the user to one end 102a of cable 102, training device 100 functions as an adjustable pulley.

[0012] The pulley group 103 is arranged to smooth the movement of the cable 102, and each pulley has a rotatable structure. The pulley group 103 shown in Fig. 1 includes pulley 103-1, pulley 103-2, pulley 103-3, and pulley 103-4. The pulley 103-4 is hung on the cable 102 and is connected to the tip of the lift shaft 105-1.

[0013] The weight stack 104 has multiple weight plates stacked vertically along the left guide shaft 105-2 and the right guide shaft 105-3. The weight stack 104 is configured so that the load applied to the cable 102 can be adjusted for each weight plate. In FIG. 1 , a weight pin P is inserted into one of the multiple weight plates. The weight plate into which the weight pin P is inserted and the weight plate positioned above it are integrated with the lift shaft 105-1. When a user performs training by pulling the handle connected to one end 102a of the cable 102, a load equivalent to the weight plates integrated with the lift shaft 105-1 is applied upward to one end 102a of the cable 102. When the user pulls down the handle against the load, the cable 102 is reeled out to the outside of the training apparatus 100. Since the other end 102b of the cable 102 is fixed to the upper frame 101-2, when the cable 102 is unwound outside the training device 100, the pulley 103-4, the lift shaft 105-1 connected to the pulley 103-4, and the weight plate integrated with the lift shaft 105-1 are lifted upward.

[0014] The pulley 103-4 is not essential to the training apparatus 100. Providing the pulley 103-4 in the training apparatus 100 provides the following effects. The pulley 103-4 is a movable pulley, and has the effect of increasing the stroke when the user pulls on a handle or the like connected to one end 102a of the cable 102. The stroke is doubled compared to when the pulley 103-4 is not provided. Providing the pulley 103-4 in the training apparatus 100 increases the stroke, thereby providing the effect of enabling more effective training. If the pulley 103-4 is not used, the tip of the lift shaft 105-1 is connected to the other end 102b of the cable 102 fixed to the upper frame 101-2 in FIG. 1.

[0015] A load control unit 200 may be disposed directly below the weight stack 104 of the training apparatus 100. The load control unit 200 is connected to, for example, the lift shaft 105-1, and can add an additional load to the training load provided by the weight stack 104.

[0016] The support device 1 supports an external device that is retrofitted to the training apparatus 100. The external device 20 is, for example, a tablet-type display device having a display screen, an operating device for the load control unit 200, or the like. The position at which the support device 1 supports the external device 20 varies depending on the purpose of use of the external device 20. For example, if a user trains in an upright position and the external device 20 is an operating device for the load control unit 200, the external device 20 is preferably placed at the eye level of the user in an upright position or at a height that allows the user to operate it without bending over. Furthermore, if the external device 20 is a display device and the user trains while looking at the display screen, the external device 20 is preferably placed in an extension of the user's line of sight while training, and at a position that does not collide with the training apparatus 100 or the user. Because the user's posture and line of sight during training vary depending on the training, it is necessary to support the external device 20 in an appropriate position.

[0017] The support device 1 can be detachably attached to the training tool 100. The user attaches the support device 1 to the training tool 100 to be used for training, and supports the external device 20 in a desired position and facing in a desired direction.

[0018] The support device 1 includes an attachment portion 10, an arm 11, and a holding portion 12. The attachment portion 10 is attached to a non-movable portion of the training apparatus 100 at a height desired by the user. The non-movable portion of the training apparatus 100 is, for example, the frame 101 of the training apparatus 100. In this application, the "non-movable portion" refers to a portion of the training apparatus 100 that does not move and provides stability during training by the user. In addition to the frame 101 of the training apparatus 100, the "non-movable portion" may also include, for example, the seat and backrest on which the user sits. In FIG. 1 , the attachment portion 10 of the support device 1 is attached to the left frame 101-3 of the frame 101 of the training apparatus 100.

[0019] The mounting unit 10 has a connecting portion 10-1. An arm 11 is connected to the connecting portion 10-1 so as to be rotatable in the yaw direction. The arm 11 is provided so that an external device 20 can be attached to its tip. For example, the arm 11 shown in FIG. 1 is a multi-joint arm having a first arm 11-1, a second arm 11-2, and a third arm 11-3. One end of the first arm 11-1 is connected to the connecting portion 10-1 of the mounting unit 10, and the other end is connected to the second arm 11-2. That is, one end of the arm 11 is connected to the mounting unit 10. One end of the second arm 11-2 is connected to the first arm 11-1, and the other end is connected to the third arm 11-3. One end of the third arm 11-3 is connected to the second arm 11-2, and the other end is connected to the holding unit 12. That is, the arm 11 is connected to the holding unit 12 at the other end opposite to the one end connected to the mounting unit 10.

[0020] The connecting portion 10-1 has a rotation axis extending in the vertical direction at a connecting portion where it is connected to the first arm 11-1. The first arm 11-1 is provided to be rotatable in the yaw direction around the rotation axis of the connecting portion 10-1. The second arm 11-2 is provided to be rotatable in the yaw direction around a connecting portion with the first arm 11-1. The third arm 11-3 is provided to be rotatable in the yaw direction around a connecting portion with the second arm 11-2. The arm 11 can change the relative position of the holding portion 12 with respect to the mounting portion 10 in the horizontal direction by rotating the first arm 11-1, the second arm 11-2, and the third arm 11-3 in the yaw direction. By moving the arm 11, the user can change the relative position of the holding portion 12 with respect to the position of the mounting portion 10 in the front-rear and left-right directions.

[0021] The holder 12 has a storage unit 12-1 and a tilting mechanism 12-2. The storage unit 12-1 stores the external device 20. The tilting mechanism 12-2 tilts the storage unit 12-1 with respect to the extending direction 11a of the third arm 11-3. The storage unit 12-1 holds the external device 20 so that the external device 20 will not fall off regardless of the direction in which it is oriented. In other words, the holder 12 holds the external device 20 so that it can tilt with respect to the extending direction 11a of the arm 11. The tilting mechanism 12-2 is, for example, a two-axis hinge, and can tilt the storage unit 12-1 in two directions that are perpendicular to the extending direction 11a of the third arm 11-3.

[0022] FIG. 2 is an enlarged perspective view of the mounting unit 10 shown in FIG. 1. As shown in FIG. 2, the mounting unit 10 has a fixed part 30 and a movable part 40. The fixed part 30 shown in FIG. 2 has a columnar shape with an L-shaped bottom, and a connecting part 10-1 protrudes from the surface of a first part 30-1. The first part 30-1 of the fixed part 30 extends in the front-rear direction, and a clamping part 30-2 extends from its front end to the right. A friction member 32 is disposed on the back surface of the clamping part 30-2. The friction member 32 is formed of an elastic member such as rubber. The friction member 32 is disposed opposite the left frame 101-3. A side surface 30-3 on the rear end side of the first part 30-1 faces the movable part 40 and has a first fitting part 33.

[0023] The movable part 40 has a second fitting portion 41 and a friction member 42. The second fitting portion 41 is disposed in a position facing the first fitting portion 33 of the fixed part 30 when the fixed part 30 and the movable part 40 are combined together. One of the first fitting portion 33 of the fixed part 30 and the second fitting portion 41 of the movable part 40 is a hole, and the other is a protrusion that fits into the hole. In FIG. 2 , the first fitting portion 33 of the fixed part 30 is a hole, and the second fitting portion 41 of the movable part 40 is a protrusion. The movable part 40 is integrated with the fixed part 30 by fitting the second fitting portion 41 into the first fitting portion 33 of the fixed part 30.

[0024] The movable part 40 is biased toward the fixed part 30. For example, the second fitting part 41 of the movable part 40 is biased toward the fixed part 30 by a spring, a solenoid, or the like arranged inside the first fitting part 33. In FIG. 2, the movable part 40 is biased forward.

[0025] The friction member 42 of the movable part 40 is made of an elastic material such as rubber and is disposed on the rear surface of the movable part 40, opposite the front surface 40-1. The friction member 42 is disposed facing the left frame 101-3. When the mounting unit 10 is attached to the left frame 101-3, the left frame 101-3 is sandwiched between the friction member 32 of the fixed part 30 and the friction member 42 of the movable part 40. In other words, the mounting unit 10 sandwiches a portion of the left frame 101-3, which is an example of a non-movable part of the training apparatus 100, between the fixed part 30 and the movable part 40. The biasing force that biases the movable part 40 presses the friction member 32 and the friction member 42 against the left frame 101-3. The mounting unit 10 prevents the support device 1 from falling by the friction force generated by pressing the friction member 32 and the friction member 42 against the left frame 101-3.

[0026] A force corresponding to the mass of the arm 11, the holding part 12, and the external device 20 is applied to the connecting part 10-1. The frictional force generated by pressing the friction members 32 and 42 against the left frame 101-3 prevents the mounting part 10 from shifting in the direction in which the connecting part 10-1 protrudes from the surface of the fixed part 30, and prevents the connecting part 10-1 from tilting downward.

[0027] The direction in which the movable part 40 is urged toward the fixed part 30 is perpendicular to the direction in which the connecting part 10-1 protrudes from the surface of the fixed part 30. Therefore, the force applied to the connecting part 10-1 from the arm 11 etc. and the force urging the movable part 40 do not cancel each other out, and the force preventing the support device 1 from falling off is not weakened. Note that the direction in which the movable part 40 is urged toward the fixed part 30 does not need to be strictly perpendicular as long as it intersects with the direction in which the connecting part 10-1 protrudes from the surface of the fixed part 30 at an angle within a range in which the function of preventing the support device 1 from falling off is not lost.

[0028] A friction member 32 is disposed between the fixed part 30 and the left frame 101-3, and a friction member 42 is disposed between the movable part 40 and the left frame 101-3. Because the friction members 32 and 42 are made of a soft material such as rubber, they can protect the left frame 101-3 from impacts and the like applied by the movable part 40 when the mounting part 10 is attached.

[0029] The mounting part 10 has the movable part 40 provided so as to be movable in the front-to-rear direction relative to the fixed part 30, so that the mounting part 10 can be attached to various training equipment with different front-to-rear dimensions.

[0030] Since the support device 1 has a multi-joint arm as the arm 11, when supporting the external device 20 at a desired position, it can appropriately circumvent the positions through which the training equipment 100 or the user's body passes during training.

[0031] Since the rotation direction of the first arm 11-1, the second arm 11-2, and the third arm 11-3 that make up the arm 11 is limited to the yaw direction, it is possible to reduce the displacement of the external device 20 in the up / down or pitch direction due to vibrations that occur during training.

[0032] Second Embodiment A second embodiment of the present invention will be described below. For ease of explanation, members having the same functions as those described in the first embodiment will be denoted by the same reference numerals, and their description will not be repeated.

[0033] The stand device 1 according to the second embodiment of the present invention differs from the first embodiment in the shape of the mounting portion 10. FIG. 3 is a plan view of the mounting portion 10 according to the second embodiment of the present invention. The mounting portion 10 shown in FIG. 3 has a cylindrical shape that encases the left frame 101-3. A portion of the side wall of the cylindrical mounting portion 10 shown in FIG. 3 constitutes the movable component 40, and the remaining portion of the side wall of the mounting portion 10 constitutes the fixed component 30. For example, the movable component 40 of the mounting portion 10 according to the second embodiment has a locking portion 40-2 located on the opposite side of the left frame 101-3 from the first component 30-1 of the fixed component 30. The portion of the movable component 40 having the surface 40-1 and the locking portion 40-2 are part of the cylindrical side wall. The locking portion 40-2 is an example of a second component. The first component 30-1 and the clamping portion 30-2 of the fixed component 30 are part of the side wall of the mounting portion 10 according to the second embodiment. The fixed component 30 has a locking portion 30-4 at a position opposite to the first portion 30-1 across the left frame 101-3. The locking portion 30-4 is a part of the cylindrical side wall and is an example of the second portion.

[0034] The mounting portion 10 of the second embodiment has the locking portion 30-4 and the locking portion 40-2 at a position opposite to the first portion 30-1, thereby preventing the mounting portion 10 from shifting in the direction in which the connecting portion 10-1 protrudes from the surface of the fixed component 30 and preventing the connecting portion 10-1 from tilting downward.

[0035] 3, friction member 32 extends between locking portion 30-4 and left frame 101-3, and friction member 42 extends between locking portion 40-2 and left frame 101-3. Friction member 32 between locking portion 30-4 and left frame 101-3 and friction member 42 between locking portion 40-2 and left frame 101-3 generate frictional force when pressed against left frame 101-3 by force applied to connecting portion 10-1 from arm 11, etc. This prevents support device 1 from falling.

[0036] [Modification] In each of the above-described embodiments, the mounting part 10 has the connecting part 10-1 provided on the first part 30-1 of the fixed part 30. However, in the mounting part 10, the connecting part 10-1 that connects the arm 11 may be provided on a part other than the fixed part 30, for example, on the movable part 40.

[0037] In the above-described embodiments, the arm 11 is a multi-joint arm including a first arm 11-1, a second arm 11-2, and a third arm 11-3. However, the configuration of the arm 11 is not limited to this. For example, the arm 11 may be a multi-joint arm including two or four or more arms, or may be a flexible arm. Furthermore, when the arm 11 is a multi-joint arm, one or more of the arms constituting the arm 11, such as the first arm 11-1, may be provided so as to be rotatable in a direction other than the yaw direction. The first arm 11-1 may be connected to the connecting part 10-1 so as to be rotatable in a direction other than the yaw direction. The connecting part 10-1 connecting the arm 11 may be provided so as to be rotatable in the roll direction around a rotation axis perpendicular to the surface of the first part 30-1 of the fixed part 30.

[0038] FIG. 4 is an enlarged perspective view of a mounting unit 10 according to a modified example of the present invention. The mounting unit 10 shown in FIG. 4 differs from the mounting unit 10 according to the second embodiment in that the connecting portion 10-1 is rotatable about a rotation axis perpendicular to the surface of the first portion 30-1 and the arm 11 is connected to the connecting portion 10-1 so as to be rotatable in the pitch direction. Also, in FIG. 4, an operating member 43 is provided on the surface 40-1 of the movable part 40. A user can easily attach the mounting unit 10 to the left frame 101-3 of the training apparatus 100 using the operating member 43. For example, the user can attach the mounting unit 10 to the left frame 101-3 by placing their hand on the operating member 43 and pulling the movable part 40 against the force biasing the movable part 40, separating the movable part 40 from the fixed part 30, and moving the mounting unit 10 so that the left frame 101-3 is sandwiched between the friction members 32 and 42. Furthermore, when a predetermined operation is performed on the operating member 43, the force urging the movable part 40 toward the fixed part 30 may be weakened. For example, when a predetermined operation is performed on the operating member 43, a spring urging the movable part 40 may be disengaged from the movable part 40, or power to a solenoid urging the movable part 40 may be stopped.

[0039] In each of the above-described embodiments, the support device 1 is retrofitted to the training apparatus 100 by attaching the attachment unit 10 to the left frame 101-3 of the training apparatus 100. However, the frame 101 of the training apparatus 100 to which the attachment unit 10 is attached is not limited to the left frame 101-3. The attachment unit 10 may be attached to a frame 101 other than the left frame 101-3, such as the right frame 101-1 or upper frame 101-2 of the training apparatus 100, for example.

[0040] In the above embodiment, the support device 1 is retrofitted to the weight stack type training apparatus 100. However, the support device 1 may be retrofitted to other types of training apparatuses other than the weight stack type training apparatus 100. For example, the support device 1 may be retrofitted to other types of training apparatus such as plate loading type or power rack type.

[0041] Fig. 5 is a schematic diagram showing another schematic configuration of a training apparatus to which a support device according to the first embodiment of the present invention has been attached. The training apparatus 100 shown in Fig. 5 is a weight stack type chest press having a seat 300 and a handle 301. In Fig. 5, the external device 20 is a tablet-type display device, and the support device 1 supports the external device 20 so that the screen of the external device 20 is positioned in the line of sight of a user sitting on the seat 300.

[0042] In some training using a weight stack type chest press, the handle 301 is operated while standing facing the seat 300 rather than sitting on the seat 300. In this case, the support device 1 may support the external device 20 at a position behind and below the seat 300.

[0043] 〔summary〕 The support device of aspect 1 of the present invention is a support device that supports an external device that is installed on a training tool as an add-on, and comprises an arm to the tip of which the external device can be attached, and an attachment part to which the arm is connected and which is attached to a non-movable part of the training tool, and the attachment part has a fixed part and a movable part that is biased toward the fixed part, and sandwiches a portion of the non-movable part of the training tool between the fixed part and the movable part.

[0044] According to the above configuration, the support device for supporting the external device can be easily attached to the training equipment.

[0046] According to the above configuration, the direction in which the connecting portion protrudes from the surface of the fixed part intersects with the direction in which the movable part is urged toward the fixed part, thereby preventing the movable part from being pulled away from the fixed part by the force applied to the connecting portion from the arm.

[0047] A support device according to aspect 3 of the present invention is the same as aspect 2 above, except that the mounting portion has a cylindrical shape, a portion of the side wall of the mounting portion constitutes the movable part, and the remainder of the side wall of the mounting portion constitutes the fixed part, the connecting portion protrudes from the surface of the side wall of the mounting portion that constitutes the fixed part, and the side wall of the mounting portion has a first portion from which the connecting portion protrudes and a second portion located on the opposite side of the first portion and the non-movable part.

[0048] According to the above configuration, the mounting portion has a second part on the opposite side of the first part from which the connecting part protrudes, thereby preventing the mounting portion from being pulled away from the non-movable part of the training equipment and falling off due to the force applied to the mounting portion from the arm.

[0049] A support device according to a fourth aspect of the present invention is the support device according to the second or third aspect, wherein the connecting portion is provided rotatable about an axis perpendicular to the surface of the mounting portion.

[0050] Some training equipment is shorter than the user. By providing a connecting part that can rotate around an axis perpendicular to the surface of the mounting part, the external device can be supported at a desired height even when it is retrofitted to short training equipment.

[0051] A support device according to aspect 5 of the present invention is any one of aspects 1 to 4 above, in which the arm has one end connected to the mounting portion and the other end connected to a holding portion that holds the external device, and is configured so that the relative position of the holding portion with respect to the mounting portion can be changed.

[0052] The desired position for placing the external device varies depending on the purpose of use of the external device and the type of training the user is performing. With the above configuration, the external device can be easily placed in the desired position by changing the relative position of the holding part with respect to the attachment part.

[0053] A support device according to a sixth aspect of the present invention is the support device of the fifth aspect, wherein the holding portion holds the external device so as to be tiltable relative to the direction in which the arm extends.

[0054] According to the above configuration, the support device can support the external device in a state where the external device is oriented in a desired direction.

[0055] A supporting device according to a seventh aspect of the present invention is any one of the first to sixth aspects, wherein the fixed component and the movable component have friction members on surfaces facing the non-movable part.

[0056] With the above configuration, the training equipment can be protected from impacts applied to the non-movable part from the fixed part and the movable part, etc. Furthermore, the force that urges the movable part toward the fixed part presses the friction member against the non-movable part, generating frictional force that prevents the support device from falling off.
