Description

FIELD OF THE INVENTION The present invention relates to a jump rope grip equipped with rope length adjustment means.

Traditionally, the length of a jump rope was adjusted to suit the user's physique by cutting the rope stored in the grip or tying a knot. Adjustment methods that involve tying a knot in the rope or cutting it short make it impossible to adjust the length of the rope to the optimum length depending on the type of jump (flat jump, cross jump, double jump, etc.). Another drawback is that once the rope is cut short, it becomes unusable as the user grows and grows larger.

Therefore, for example, in Patent Document 1, a function to adjust the length of the rope is provided by fitting a tightener through which the rope is inserted into a rotating terminal inside the grip, without cutting the rope short or tying it. have been disclosed.

Further, Patent Document 2 discloses a device equipped with a means for adjusting the length of the rope by folding and holding the end of the rope in a holder housed inside the grip and changing the amount of folding. .

(Embodiment)
As shown in FIGS. 1-5, the jump rope grip of this embodiment includes a grip body 10 and a length adjustment means for adjusting the length of the rope 40 inside the grip body 10. The means includes a rotor 30 that slides the rope 40 inserted into the grip body 10 and fixes the rope 40 at an arbitrary position, and an operating body 20 that switches the rope 40 by the rotor 30 between a fixed state and a free state. The rotor 30 has an outer rotor 31 and an inner rotor 32 that are formed separately, and the operating body 20 has an outer rotor 31 and an inner rotor 32 formed separately. The main part is to operate the inserting operation in conjunction with each other.

As shown in FIG. 1, the grip body 10 has a cylindrical shape that tapers from the rear end to the tip, and is provided at the front end side of the grip body 10, and has a recess 11 in which the operating body 20 is placed, and a recess 11 in which the operating body 20 is fitted. It has an opening part 12 that communicates the joint part 20b with the inside.

In addition, as shown in FIG. 2, the grip body 10 has a cross-sectional shape that is approximately triangular on the tip side so that it is easy to hold depending on the way you grip it (so-called gripping, holding a mouse with your index finger extended, holding a remote control with your thumb extended, etc.). It is continuously formed so that the rear end side is approximately elliptical. Furthermore, finger rests 14 are provided at the portions where the thumb and index finger are placed depending on the grip. Note that the terms "substantially triangular" and "substantially elliptical" herein include those with rounded vertices and sides.

The grip main body 10 is mainly made of a synthetic resin material that is entirely or partially transparent so that an indicator 41 (to be described later) and the state of the rope 40 can be visually confirmed, and the grip body 10 has a display section that shows the adjusted length of the rope 40. It has 13. This display section 13 is a combination of character strings such as LONG (long), MIDDLE (middle), SHORT (short), and a scale made up of equally spaced horizontal lines.

As shown in FIGS. 1 and 2, the operating body 20 includes a slider 20a that slides along the longitudinal direction with respect to the recess 11 of the grip body 10, and a slider 20a that protrudes toward the inside of the grip body 10 from the lower surface of the slider 20a. It has a fitting part 20b that loosely fits into the flange part 32b of the inner rotor 32.

The slider 20a has an upright piece 20c on its upper edge and a plurality of protrusions 20d, 20d on its upper surface so that the user can easily switch between a fixed state and a free state with a fingertip.

The fitting portion 20b is fitted loosely along the outer surface of the flange 32b so as to fit loosely to the flange 32b of the inner rotor 32 of the length adjusting means so as not to impede the rotational movement of the rotor 30. It is formed into a groove shape with a width larger than the thickness of the flange portion 32b (for example, see FIGS. 4 and 5).

As shown in FIG. 1-3, the rotor 30 is fitted into an outer rotor 31 rotatably attached to the grip body 10 through which a rope 40 is inserted, and a fitting hole 31a of the outer rotor 31. and an inner rotor 32 that engages the rope 40.

The outer rotor 31 has a substantially cylindrical shape and has a fitting hole 31a into which the inner rotor 32 is fitted from the rear end side. The fitting hole 31a may be formed into a cylindrical body having almost the same shape as the outer circumferential shape of the inner rotor 32, or may have a tapered truncated conical shape whose inner diameter becomes narrower than the outer diameter of the inner rotor 31 toward the tip. You may also do so. Further, the outer rotor 32 is rotatably housed between the inner side of the tip of the grip body 10 and the upper end of the inner plug 33.

The inner rotor 32 has a substantially cylindrical shape through which the rope 40 is inserted, and has claws 32a, 32a protruding from the rear end of the outer circumferential surface. It has a flange portion 32b provided therein. At least two claw parts 32a, 32a are provided on the outer circumferential surface of the inner rotor 32, and have enough elasticity to be elastically deformed when inserted into the insertion hole 31a of the outer rotor 31. Note that the inner rotor 32 may be formed with a plurality of narrow grooves along the longitudinal direction in order to be elastically deformed and to make it easier to hold the rope 40.

Further, the length adjusting means has an inner plug 33 fixed to the distal end side of the grip main body 10 and housing the rotor 30 inside the distal end of the grip main body 10. This inner plug 33 has a housing portion 33a that accommodates the inner rotor 32 of the rotor 30, and a protrusion 33b that engages and fixes inside the tip side of the grip body 10. The accommodating portion 33a has an opening in a portion where the fitting portion 20b of the operating body 20 and the flange portion 32b of the inner rotor 32 engage with each other. Further, in this accommodating portion 33a, when the rope 40 is fixed, which will be described later, the distal end side of the inner rotor 32 protrudes and is fitted into the insertion hole 31a of the outer rotor 31 disposed on the distal end side from the inner plug 33. 40 has a storage space with a vertical width that is large enough to fit into the storage portion 33a in the free state.

The rope 40 is preferably made of a synthetic resin material such as polyvinyl chloride (PVC) and has a diameter of about 3.8 mm to 4.0 mm so that it is light and easy to jump. An indicator 41 is attached to indicate the position within the grip body 10. This indicator 41 is clamped and fixed via an inserted sleeve tube 42, and is aligned with the display section 13 of the grip body 10.

Next, a method of adjusting the length of the rope 40 using the above-mentioned jump rope grip will be explained based on FIGS. 4 and 5.

First, in order to adjust the length of the rope 40, a free state in which the fixed state of the rope 40 by the rotor 30 is released is shown in FIG. By pushing down the slider 20a of the operating body 20 in the grip body 10 toward the rear end, the inner rotor 32 fitted into the outer rotor 31 moves in conjunction with the rear end direction, and is operated to be unfitted. At this point, the rope 40 becomes free. Since the rope 40 is not engaged by the claws 32a, 32a of the inner rotor 32, the rope 40 on the distal end side of the grip body 10 can be pulled up or pushed down to create a rope of any length. It is possible to change it inside the grip main body 10 so that it becomes 40. In addition, by aligning the indicator 41 attached to the lower end of the rope 40 with the display section 13 of the grip body 10, the length of the rope can be changed to the character string SHORT (shorter), MIDDLE (middle), and LONG (longer) on the display section 13. ), and the scale may be used as a guide for adjustment.

As shown in FIG. 5, after adjusting the length of the rope 40, by pushing up the slider 20a of the operating body 20 in the grip body 10 toward the distal end, the fitting portion 20b of the operating body 20 is connected to the inner rotor 30. Since the inner rotor 32 is loosely fitted to the flange portion 32b of the outer rotor 31, the inner rotor 32 moves in conjunction with the distal end direction and is operated to be inserted into the insertion hole 31a of the outer rotor 31. At this time, the claws 32a, 32a of the inner rotor 32 are elastically deformed in the center direction, thereby engaging to sandwich the rope 40 and becoming in a fixed state. At this time, the collar portion 32b of the inner rotor 32 is loosely fitted to the fitting portion 20b of the operating body 20, and is freely rotatable in the direction of rotation of the rope 40 when the user jumps rope. It becomes.

Therefore, with the above-mentioned jump rope grip, in order to set the rope 40 to the optimum length according to the physique and jumping style of the user, by operating the operating body 20 of the grip main body 10, the arbitrary length of the rope 40 can be quickly adjusted. It is possible to adjust to

Although the preferred embodiments of the present invention have been illustrated in the above embodiments, the present invention is not limited to the above embodiments, and improvements and changes can be made within the scope of the claims. For example, the operating body 20 may be placed at a position on the outer peripheral surface of the grip main body 10 where it can be easily operated, and may be changed to an appropriate position taking into consideration the size of the user's fingers.
