Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to exercise equipment, in particular, swaying by holding the elastic bar gripping part and vibrating both ends of the elastic rod to effectively exert a load on muscles, thereby reducing muscle strength and endurance. It relates to the body blade to train.

[0002]

[Prior art]

 In recent years, many indoor exercise equipments having various functions have been developed, and among them, the body blade is one of the most popular exercise equipments.

As shown in FIG. 6, the conventional body blade has a rod-shaped spring bar (30), and iron blocks (31) are inserted into both ends of the spring bar (30) by welding, respectively. The outer periphery of the spring bar (30) is covered with a covering (32) made of a sponge material up to the positions of the iron blocks (31) on both sides, and the covering (32) at both ends of the spring bar (30) and the iron block (31). By covering the obstruction body (33) with the iron block (31), injury to the human body due to the iron block (31) is prevented.

[0004] In addition, the method of use is to hold the center of the spring bar (30) by hand, swing the spring bar (30) with the force of the hand, and hold the holding portion by the reaction of the spring bar (30). By flexing both sides (unsigned), the muscles such as the hands, elbows, shoulders, and chest are put on a proper load to strengthen muscle strength and endurance.

[0005]

[Problems to be solved by the present invention]

 However, the conventional body blade has the following disadvantages. <B> The elasticity of the conventional body blade is due to the coil spring, which is wound in the axial direction. When the spring bar is vibrated in the vertical direction, the wires of the coil spring collide with each other. In addition to generating noise, the impact force of the collision is transmitted to the muscles of the human body and forces are applied to the joints of the arms, which may cause injury to the human body. Also, the greater the vibration, the greater the impact force, and the shorter the coil pitch, the more likely the collision phenomenon occurs. <B> Although a cover made of a sponge material is provided on the outer periphery of the spring bar, it tends to burst when used for a long time, and cannot be used if the spring bar is exposed. Further, since the cover is tightly covered with a rod-shaped spring rod, it is difficult for the user to replace the cover by himself. <C> Since the conventional body blade is composed of a combination of a number of members such as a spring bar, a cover, and a closing body, the process becomes complicated and the manufacturing cost increases.

[0006]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention has a rod-shaped elastic rod (10) made of a flexible material, and a grip portion (11) is provided at the center of the elastic rod (10). At the same time, small-diameter portions (12) having smaller diameters than the grip portion (11) are provided on both sides of the grip portion (11), respectively, and a weight adjusting weight member () is provided at the end of each small-diameter portion (12). 14. A body blade, which is characterized in that 14) is combined.

[0007]

[Action]

 The present invention has the above structure, that is, it has a rod-shaped elastic rod made of a flexible rubber material, and a grip portion is provided at the center of the elastic bar, and both sides of the grip portion are provided. Each of the small-diameter portions has a smaller diameter than the grip portion, and a weight member for adjusting the weight is combined at the end of each of the small-diameter portions, so that the conventional spring bar is vibrated in the vertical direction. At this time, no collision occurs between the wires in the coil spring, and no force is applied to the joints of the arms by the impact force of the collision, so there is no risk of injuring the human body. Therefore, excellent flexibility and safety can be maintained.

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is an exploded perspective view of the body blade according to the present invention, FIG. 2 is a partially transparent perspective view of the body blade according to the present invention, and FIG. 3 is an elasticity of the body blade according to the present invention. FIG. 4 is a partial side cross-sectional view when a weight member is mounted on a rod, FIG. 4 is a reference view showing a use state of a body blade according to the present invention, and FIG. 5 is another embodiment of a body blade according to the present invention. FIG.

As shown in FIGS. 1 to 3, the body blade of the present invention has an elastic rod (10) formed by injection-molding a flexible rubber material, and a grip portion is provided at the center of the elastic rod (10). (11) is provided, a non-slip groove portion (no symbol) is formed on the surface of the grip portion (11), and a diameter of the grip portion (11) is larger than that of the grip portion (11) on both sides. A small diameter portion (12) having a small diameter is provided, and a weight member (14) for adjusting the weight is combined with the end of each small diameter portion (12).

Although there are several types of the weight member (14), those shown in FIGS. 1 to 3 show that when the elastic rod (10) is formed, one end of the threaded rod (15) is attached to the elastic rod (15). The other end of the threaded rod (15) is integrally provided in both ends of the rod (10), and the other end is exposed to the outside. The whole is columnar, and the threaded hole (141) formed at one end is It is screwed into the screw rod (15) at the end of the elastic rod (10). As shown in FIG. 5, when forming the elastic rod (10), the weight member (16) may be embedded in both ends together with the elastic rod (10).

As shown in FIG. 4, when using the present invention, the gripping part (11) of the elastic rod (10) is gripped by hand, and the elastic rod (10) is swung by hand. The small diameter portion (12) and the weight member (14) located on both sides of the hand portion are vibrated. And this vibration causes the muscles, hands and elbows to exert an exercise effect.

[0012]

[Effect of the invention]

 Since the present invention has the above configuration, the following effects can be obtained. <B> The body blade of the present invention has a rod-shaped elastic rod made of a flexible material, a grip portion is provided at the center of the elastic rod, and the both sides of the grip portion each have a diameter larger than the grip portion. Small diameter portions are provided, and weight members for adjusting the weight are combined at the ends of each small diameter portion.Thus, the small diameter portion having a small diameter can provide good bending, and the weight member can increase the magnitude of vibration. Can be adjusted appropriately. Therefore, the collision between the wires in the coil spring when the spring bar is vibrated in the vertical direction does not occur, and no force is applied to the arm joint by the impact force of the collision. In addition to eliminating the danger of giving exercise, excellent safety and moderate exercise effects can be achieved.

<B> The present invention eliminates the need to separately cover the cover made of sponge material as in the prior art, and directly injection-molds a flexible rubber material into the elastic rod, so that the production can be performed quickly. And the manufacturing cost can be reduced.

<C> The weight member shown in FIG. 1 adopts a detachable method, and the user can freely combine weight members having a desired weight, which is excellent in practicality. In another embodiment shown in FIG. 5, the weight member is embedded in the elastic rod. According to this configuration, the product can be completed in one step, so that the manufacturing cost can be reduced and the manufacturing time can be shortened. As described above, since the body blade of the present invention may adopt either of the designs, the range of use is extremely wide.
