Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chair for a muscle strength measuring apparatus, and more particularly to a seating apparatus for fixing a joint at a measurement site in a stable manner by fitting it to an input shaft of a muscle strength measuring apparatus body.

[0002]

[Prior Art]

 A device for measuring the muscle strength of various parts of the body is provided, which comprises a measuring device composed of a mechanical part and an electronic part, and a seating device for stably fixing the body of the person to be measured. The seating device is intended to stably fix the body of the person to be measured by properly aligning the joint of the portion to be measured with the input shaft of the measuring device.

[0003]

[Problems to be solved by the device]

 However, since the seating device moves the muscles of the site where the person to be measured sits down and actually measures, it requires strength and each part must be adjustable, so the existing normal Can not be made in time with the chairs, and requires a special configuration.

In view of the above-mentioned circumstances, an object of the present invention is to provide a chair that can be used as a seating device for a muscle strength measuring device.

[0005]

[Means for Solving the Problems]

 The chair for a muscle strength measuring device according to the present invention is such that a pedestal is movably mounted in the front-rear direction on a base that can be placed and fixed on the floor, etc., and a seat device is fixed on the pedestal. It is characterized by comprising a seating part, a seat restraint, and a tiltable backrest part that can be tilted and fixed at a desired angle.

[0006]

[Action]

 Move the seat device in the front-rear direction to determine the desired position, set the seat to the desired height, determine the inclination angle so that the backrest can take the optimum sitting posture, and then sit on the seat. A seat restraint can be attached to stabilize and fix the body, and proper muscle strength can be measured.

【Example】

 An embodiment of this invention will be described below. As shown in FIGS. 1 to 4, a pedestal 2 is placed on the upper surface of a base 1 so as to be movable in the front-rear direction, a seat device 3 is formed on the pedestal 2, and the seat device 3 is seated by a seat portion 4. And a backrest portion 6 to which a seat restraint 5 such as a seatbelt is attached, and the backrest portion 6 is tilted so that it can be fixed at a desired angle in the front-rear direction.

The base 1 is formed by firmly forming a quadrilateral frame body having a predetermined area, fixing tools 1a, 1a provided on the bottom surface of the front part thereof, and casters 1b, 1b provided on the rear part thereof, and both side parts. The middle frames 1c and 1c are connected between them. An appropriate supporting member 7a is suspended between the middle frames 1c, 1c, and a rail 7 is fixed on the supporting member 7a in the front-rear direction.

Slide blocks 8, 8 are straddled on the rail 7, and a gantry body 2 a is fixed to the slide blocks 8, 8. Therefore, the gantry 2 can move in the front-back direction of the base 1. A plurality of through holes 7b are formed on the side surface of the support member of the rail 7 at predetermined intervals, and lock pins 9 which can be engaged with and disengaged from the through holes 7b are attached to a bracket 2b fixed to the gantry body 2a.

As shown in FIGS. 5 (a) and 5 (b), the rail 7 and the slide block 8 have concave portions 7c and 7c formed on both side surfaces thereof, and arc-shaped grooves 7d and 7d are formed at upper and lower corner portions on both right and left sides thereof. A reverse concave slide block 8 is laid on the formed rail body, and circulates through the endless hole 8a in the slide block 8 between the slide block 8 and the arcuate grooves 7d and 7d. The ball bearing 8b is interposed.

The backrest portion 6 has a stay 11 projecting obliquely forward at a predetermined angle on the rear portion of the rod seat 10 placed at a substantially central portion along the longitudinal direction of the pedestal 2, and further, the stay 11 and the rod. The seat 10 is connected and the backrest isch 12 extending upward by a predetermined length is connected, and the cushion 13 is fixed to the backrest 12. The front portion of the rod 10 is rotatably connected to the front portion of the gantry 2 by a pivot 14, and the seating portion 4 is connected to the tip of the rod 10. A seat restraint 5 including a belt is connected to the stay 11.

Further, an inner pipe 17 is connected to a substantially central portion in the longitudinal direction of the backrest isch 12 via a bracket 15 and a pivot 16, and an outer pipe 18 for coaxially expanding and contracting the inner pipe 17 is provided. It is rotatably connected to the gantry 2 via a pivot 19. A lock pin 21 is attached to the upper end of the outer pipe 18 so as to engage with and disengage from through holes 20 (see FIG. 6) formed in the inner pipe 17 at predetermined intervals in the longitudinal direction.

The seating portion 4 has an outer pipe 22 connected to an end portion of the rod 10 and a seat cushion 24 attached and fixed to an upper end portion of an inner pipe 23 coaxially fitted to the outer pipe 22. A lock pin 25 is fixed to the outer pipe 22, and the lock pin 25 can be engaged with and disengaged from a through hole formed at a predetermined interval in the longitudinal direction of the inner pipe 23.

As shown in FIG. 6, the lock pin 21 has a tubular body 30 fixed orthogonally to the outer tube 18 and the like, and a threaded portion 31 is provided on the inner circumference of the tubular body 30 and screwed into the threaded portion 31. The inner cylinder 32 is inserted, and a spring 34 is elastically mounted between the inner cylinder 32 and the lock pin body 33 to urge the lock pin body 33 through a washer 35 which presses the lock pin body 33 against the rod. This is done by pulling the grip 36 attached to the outer end portion of the lock pin main body 33 and engaging the inner end portion of the lock pin body 33 with the through holes 20 formed at regular intervals in the height direction of the inner pipe 17 or the like. The lock pins 9 and 25 have substantially the same structure as the above.

The operation of the above embodiment will be described. When the lock pin 9 is pulled out to disengage the base 1 and the gantry 2 and the gantry 2 is moved in the front-rear direction, the seat device 3 is moved to the rail 7. Since it can be moved in the front-back direction of the base 1, the pedestal 2 and the seat device 3 movably fixed thereto can be attached to the base 1 by engaging the lock pin 9 with the through hole 7b at an appropriate position. It is fixed to and becomes stuck.

Next, the lock pin 25 is pulled out, the seat 4 is moved up and down, and the lock pin 25 is released at an appropriate position, whereby the height of the seat 4 can be adjusted. Further, by pulling out the lock pin 21 to extend / contract the inner pipe 17 from the outer pipe 18 and releasing the lock pin 21 at an appropriate position, the inclination angle of the backrest portion 6 can be set to an optimum angle for itself. When the inclination angle of the backrest portion 6 is inclined to move forward, the rod seat 10 rotates counterclockwise about the pivot axis as shown in FIG. Since the seat cushion 4 is also inclined, the seat cushion 4 changes in inclination angle.

Thus, when the front-back position of the seat device 3, the height of the seat portion 4 and the inclination angle of the backrest portion 6 are respectively determined, the training person 26 sits on the seat portion 4 as shown in FIG. Then, the seat restraint 5 is attached, and in this state, for example, the arm 27 is rotated to perform muscle training.

[0018]

[Effect of the device]

 According to the present invention described above, the seat restraint is attached to the seating portion, the backrest portion can be tilted so that the backrest portion can be fixed at a desired angle, and the entire seating device can be moved forward and backward on the base. Since it is configured so that it can be moved to, it can be used as an optimal seating device for a muscle strength measuring device, and can also be used as a seating device for solidifying the posture for proper and effective strength training with various strength training devices. Yes, it is versatile.
