Description

[Detailed description of the invention] This invention relates to a reciprocating motion detector device that is attached to an exercise machine that reciprocates, such as an indoor rowing machine, and counts the reciprocating motion. It relates to something that can be installed in a predefined state.

Conventionally, there are devices that are linked to exercise equipment such as indoor rowing machines for health management, but this proposal is designed to be attached to such exercise equipment to measure the number of times you exercise and count the amount of exercise. In such a device, the positional relationship between a detection element such as a Hall element and a detected object such as a magnet is defined in advance so that accurate reciprocating motion can be detected and the device can be easily attached to exercise equipment. This is what I did.

Hereinafter, the reciprocating motion detector of the present invention will be explained according to the embodiment shown in the drawings. 1 is an indoor rowing machine, and this rowing machine 1 is installed in a fixed cylinder cylinder 3 by pulling an arm 2 which serves as an oar. The cylinder shaft 4, which is a moving body, is pulled out against the pressure of the spring in the fixed cylinder cylinder 3, and can perform reciprocating motion as if rowing a boat.

Furthermore, the moment of this arm 2 changes by raising and lowering the shaft fulcrum 4. The length of the pullout (the moving distance) changes.

Reference numeral 5 denotes a reciprocating movement detection device attached to the surface of the fixed cylinder 3 on the side from which the cylinder shaft 4 protrudes.

In this detection device 5, a case 6 is fixed to the surface of the fixed cylinder 3 on the side where the cylinder shaft 4 protrudes, and has an open lower portion on the side where the cylinder shaft 4 protrudes, and has a detection element fixing rib 8 and a slider on the inner surface of the case. Support plate fixing ribs 9, 9 are provided protrudingly.

Reference numeral 10 denotes a detection element such as a Hall element attached to the detection element fixing rib 8.

Reference numeral 11.11 denotes a pair of slide support plates fixed by screws between the slide support plate fixing ribs 9, 9, and these slide support plates 11, 11 have sliding slots 12.12 on their opposing sides. It has been deleted.

13 is a sliding groove 12 of the slide support plates 11, 11.
, 12, and is supported slidably in the direction of the slot. One end of this sliding plate 13 protrudes from the open lower part of the case 6, and the tip is bent. This serves as the action section 14.

Reference numeral 15 denotes a biasing coil spring stretched between the hooking portion 16 of this sliding plate 13 and the case 6;
3 in the projecting direction at all times.

Reference numeral 17 denotes an object to be detected, such as a magnet, fixed to a location of the sliding plate 13 corresponding to the detecting element 10, which comes into contact with and separates from the detecting element 10 as the sliding plate 13 slides.

Reference numeral 18 denotes a contact plate disposed around the axis X of the cylinder shaft 4 with respect to the arm 2, and the acting portion 14 of the sliding plate 13 is brought into elastic contact with the plate surface to prevent further protrusion of the sliding plate 13. This prevents the sliding plate 13 from moving when the arm 2 is pulled, that is, the abutting plate 18 is in the A position, and when the arm 2 is loosened, that is, the abutting plate 18 is in the B position.
By abutting and locking the action portion 14 of the cylinder shaft 4, the sliding plate 13 slides with the reciprocating movement of the cylinder shaft 4, and the detected object 17 is brought into contact with the detecting element 10, thereby causing the detecting element to A detection pulse signal is obtained from 10.

Further, even if the cylinder shaft 4 protrudes beyond the A position, the operating portion 14 does not protrude beyond the A position.

Reference numeral 19 denotes a digital display counter attached to the rowing machine 1, which inputs the detection pulse signal from the detection element 10, counts the number of reciprocations, and displays the result digitally on the display surface 20.

The reciprocating device for exercise equipment of the present invention is as described above, and in particular, in a device that counts the number of reciprocations of a movable body relative to a fixed body due to the reciprocating motion of the exercise machine, the case is attached to the fixed body and has a detection element fixed thereto. a sliding plate that is slidably supported by the case and has one end protruding from the case; and a detected object that is fixed to the sliding plate and moves toward and away from the detection element by sliding of the sliding plate. and a contact plate that is provided on the moving body and makes elastic contact with one end of the sliding plate to cause the sliding plate to slide as the moving body reciprocates. It is possible to obtain something that can be easily attached to exercise equipment with the positional relationship between the detection element and the object to be detected being completely defined within the case, and thus can accurately count the number of reciprocations of a moving object with respect to a fixed object. can.

Furthermore, according to the present invention, the reciprocating motion of the movable body is transmitted to the sliding plate through one end that is in elastic contact with the contact plate, and the sliding plate is slid, so that the number of reciprocating motions of the movable body can be calculated regardless of the amount of reciprocating motion of the movable body. You can get what you can detect.
