Abstract

A hand grip device comprising a rotatable bail is provided to help a user take grip exercise easily without doing damage to palmar skin or slipping out of user's grasp during the grip exercise. A hand grip device(1) comprising a rotatable bail includes a head body(12) integrated with a bail by inserting a semicircular sliding unit into a semispherical sliding curve surface(5), an elasticity control unit(8) and a support unit(9) placed in a receiving part(6), and an elasticity control handle(7) placed in a cylindrical control part. The head body integrated with a bail is fitted with an axial pin(2). A compressive spring and an auxiliary spring(11) are interposed between the sliding unit and elasticity control unit. A sliding protruded structure(5a) protruded from the semispherical sliding curve surface is connected to a sliding concave unit(10a) of a semicircular sliding support unit(10). A fixed protrusion and a triangular protrusion are provided on the lower end of a bail axis, and a rotational body(18) is put on the lower part of the bail axis(15) to rotate around a bail axis rod(20), wherein an elastic spring(19) is placed under the rotational body. The rotational body comprises an inclined lower groove, an inclined top part, and protruded structures(21,21'). As the protruded structures are inserted into both groove structures(14,14') within the rotational bail(13), the rotation body revolves with rotation of the rotational bail, and the triangular protrusion is connected to the inclined lower groove to achieve going up and down, rotation, and restoration to the original state. A spring(17) is fitted into a lower guide groove of the bail axis and an upper guide groove of the rotation body. An upper end of the spring is fixed to the bail axis, and the lower end of the spring is fixed to the rotation body. As the rotation body revolves, the spring is twisted to widen, and is, after the widening, restored to the original state by elasticity.

The present invention is to hold the handle of the gripper grip when the rat is the grip movement, the rotation of the rotary handle is rotated by the elasticity of the torsion spring inside the handle to be released to repeat the handle, so that the grip can be smoothly Is about the rotating gripper,

Conventionally, the applicant of the present application filed on June 13, 2008, the "hand grip rotates the grip" there is a tilting configured in the rotating body by rotating the rotating body is inserted into the groove groove by the rotation knob rotation during the grip movement As the triangular projection of the handle shaft slides up and down the slope from the bottom groove to the inclined vertex, the triangular projection at the bottom of the handle shaft is gradually rotated and returned to its original position by the elastic spring elasticity. It is connected to the inclined apex from the inclined low point groove of the rotating body and grasped the rotation handle by the sliding action of ascending and descending. It did not damage it, and was able to conveniently and easily exercise grip.

The present invention is different from the configuration in which the handle of the gripper, the applicant of the present application as described above rotates the built-in torsion spring between the handle shaft and the rotating body and the top end of the spring is fixed to the handle shaft, the bottom end of the spring is rotated It is a defensive concept for the first application where the handle is rotated by fixing it to the whole so that the torsion of the spring occurs when the rotor rotates, and after the rotation, the rotor rotates to the original position with the restoring force of the spring. As drawn from, when described in detail by the accompanying drawings as follows.

Cylindrical adjustment of the resilient fitting 8 and the support 9 to the head body 12 and the receiving body 6 inside the head body 12 integrated with the handle by inserting the sliding sphere of semi-circular cross section into the hemispherical sliding curved surface 5. Configure the elastic adjustment handle (7) in the section (4),

The head body 12 'integrated with the handle 13' is bonded to the shaft pin 2, and the compression spring 3 and the auxiliary spring are formed between the sliding hole 8 and the elastic adjustment port 8 of the semi-circular cross section. 11) to the head body 12 to protrude the sliding protrusion (5a) to the hemispherical sliding surface (5) on the head body 12 to be connected to the sliding request (10a) of the half-moon sliding support (10),

A fixed protrusion and a triangular protrusion are formed at the lower end of the handle shaft 15, and the rotor 18 is inserted at the lower portion to slide in the handle shaft 20, and the inclined bottom groove and the inclined vertex part and the protrusion 21 and 21 'are provided. Underneath the rotating body 18, the elastic spring 19 is supported, and the cap 22 is covered with the end of the lower end of the shaft, and the protrusions 21 and 14 are formed on both side grooves 14 and 14 'in the rotary knob 13. 21 '), so that the rotating body is rotated in accordance with the rotation of the rotary knob 13,

In the gripper (1), the handle is rotated, characterized in that the triangular projection is connected to the inclined bottom groove inclination of the rotating body to the lifting and lowering and rotation and the original position to the inclined peak portion,

Insert the spring (torsional rotation spring) 17 into the guide groove 15 'at the bottom of the handle shaft 15 and the guide groove 18' at the top of the rotor 18, and the upper end 16 is the handle shaft 15. ), And the lower end 16 'is fixed to the rotating body 18 so that the spring 17 is twisted and rotated according to the rotation of the rotating body, and then returned to its original position by elasticity. It is characterized by

Referring to the operation of the present invention as described above is as follows.

In Figure 1, the handle 13 'is located in the palm of the hand, and the rotary knob 13 is grasped by grasping the inner surface of the four fingers, the rotary knob 13 is gripped to be connected to the handle 13', the upper end The compression spring (3) is compressed together with the auxiliary spring (11), the sliding request (10a) of the half-moon sliding support (10) is slid vertically up or down in the sliding projection (5a) to the compression spring (3) Corresponds to the bend (curved) of the,

At this time, the rotary knob 13 rotates by a distance connected to the handle 13 ', and when the rotary knob 13 rotates, the protrusions 21 and 21' fitted into the grooves 14 and 14 '. Is rotated in accordance with the rotation of the rotary knob, and the lower end 16 'of the torsion spring 17 is fixed to the rotor 18 during rotation. In the example, as shown in the solid arrow direction, the spring 17 is opened, and when the release knob 13 is released, the spring 17, which is twisted and opened, is restored to its original position by rotating the rotor 18 by the elastic force to be returned to its original position. Rotating body 18 rotates to its original position and groove grooves 14 and 14 'with protrusions 21 and 21' are rotated by the force to be rotated by the handle 13 to rotate. Is restored to its original position,

That is, because the upper end 16 is fixed to the handle shaft 15 and the lower end 16 'is fixed to the rotor 18, the elasticity of the spring restored by twisting and elasticity of the spring 17 is restored. The rotary knob 18 is to be rotated by.

According to the present invention, the spring of the torsion is fixed when the upper end is fixed to the handle shaft, and the lower end is fixed to the rotating body, when the rotating handle rotates (when picked up by hand), the spring is opened when the handle is released and the rotating handle is released. Since the rotation handle is rotated in the reverse position by the restoring force of the present invention, the applicant of the present application invented a defensive concept by simplifying the rotation method of the gripper to which the handle is elected. It is effective to exercise smoothly without any damage from the skin of the inside or the dislocation of the hand in the process of getting rid of the rat.
