Description

  The present invention relates to a motion for pushing and lifting a load, such as weight lifting, power lifting, etc., for training using a barbell or similar bar material, which has a relatively simple structure. It is related with the training machine which can exercise safely in.

  What is well known as a kind of exercise equipment is a barbell (in this application, when simply described as a barbell, it means a barbell set in which a bar or a disk as a load material is attached to the bar. )

  The barbell has a structure in which disc-shaped weights (discs), spherical weights, and the like are attached to both ends of the bar or in the vicinity of the ends. A shoulder press that lifts the barbell upward from the shoulder and trains the strength of the arms and shoulders, a squat that stretches the knee and stretches the strength of the legs and hips while holding the barbell on the shoulder, sleeps on the bench Bench press that pushes the barbell upward from the chest to strengthen the power of the arms, chest, shoulders, etc., and well-known snatch and clean and. Used for various training methods such as weightlifting like jerk.

  By the way, in order to perform training using a barbell, a device that supports the barbell is often used (see, for example, Patent Document 1). However, in the support device disclosed in Patent Document 1, the barbell may fall if the inner side of the bar weight is not carefully placed on both metal fittings while balancing the left and right of the barbell, and the user may be in a posture. If it breaks down, it is difficult to support the barbell, resulting in danger to the user. Therefore, in Patent Document 2 and Patent Document 3, a link or cable is connected to the barbell bar to allow the bench press or the like to move while restricting the barbell from falling toward the user. A support device is disclosed.

  However, the support device for barbells disclosed in these documents has a problem that the manufacturing cost is increased by the amount of the link and the cable, and the device becomes large. Furthermore, in order to maintain the mobility and safety when using the barbell, there is a problem that the maintenance of links, cables and other components is troublesome and difficult.

  Further, in Patent Document 4, the support mechanism is configured to include a pair of support portions and a base portion, and the support portion is provided on the bar so that the support mechanism is displaced integrally with the rod. As a result, even if the user suddenly loses his / her posture, the base part is placed on the placement surface, which restricts the movement of the weight and bar, and the weight and bar impact the user. It is said that the safety of training using a barbell can be advantageously improved.

“Analysis of Raising Technology from Barbell's Trajectory: Snatch Event” (CiNii 091 Country C14, Japan Society of Physical Education (44B) pp.632 19931005, Tadao Isaka: Ritsumeikan University, Naoki Okamoto: Ritsumeikan University, Kazuo Funato : University of Tokyo)

  However, even in the apparatus disclosed in Patent Document 4 described above, it can be said that exercise using a barbell or the like can be performed safely, but for example, the same as a delicate and exquisite barbell operation in a weightlifting competition or the like Or, if it can be said that it is possible to safely cope with the movement of the bar which can be said to be almost equivalent (for example, see Non-Patent Document 1: FIG. 8), the fact is that it cannot be said. In addition, although safety can be achieved for the time being, the device has a completely different structure from that of actual weightlifting, powerlifting, and other competitions, and improvements are also desired in this respect.

  Among the training machines according to the present invention, the training machine according to claim 1 is a training machine that performs a motion to push up and lift a load such as weight lifting and power lifting, and a support frame and a base end side to the support frame. A pair of arm-like bodies supported so as to be pivotable in the vertical direction, a long connecting member for connecting the pair of arm-like bodies, and a rod or a hydraulic pressure or pneumatic pressure provided so as to be able to protrude and retract above the casing. It consists of a cylinder and a bar that can attach the load to both ends, and has both ends supported by the arm-like body, and is supported by attaching the lower end of the casing of the cylinder to the support frame so as to be vertically rotatable. And attaching the rod of the cylinder to the connecting member at a central position of the pair of arm-like bodies, The cylinder is connected to the cylinder so as to be pivotable in the vertical direction, and a buffer valve for allowing the liquid or gas existing inside the casing of the cylinder to freely pass through or to reduce the passage amount is connected. When the arm-like body rotates upward, the rod does not resist the protrusion operation from the casing, and when the arm-like body rotates downward, the rod does not move into the casing. It becomes resistance and becomes means for buffering the descending speed of the arm-like body.

  According to the second aspect of the present invention, in the training machine according to the first aspect of the present invention, the training machine according to the first aspect includes load connecting means that is attached to the tip of the arm-like body so as to be rotatable in the vertical direction, and the bar is attached to the load connecting means. It is characterized by.

  According to a third aspect of the present invention, in the training machine according to the second aspect, the load connecting means includes a second arm-like body having a base end attached to the arm-like body so as to be rotatable in the vertical direction. The bar is attached to the free end of the second arm-shaped body.

  According to the fourth aspect of the present invention, in the training machine according to any one of the first to third aspects, the pair of arm-shaped bodies are positioned with the support frame interposed therebetween, and the support frame is a wide box-shaped frame body. Thus, the width dimension of the support frame and the width dimension between the pair of arm-shaped bodies are substantially equal to the distance between the pair of loads attached to the bar.

  The fifth aspect of the present invention is the training machine according to any one of the first to third aspects, wherein the pair of arm-shaped bodies are positioned with the support frame interposed therebetween, and the support frame is a narrow columnar frame body. The width dimension of the support frame is smaller than the width dimension between the pair of arm-like bodies and the distance between the pair of loads attached to the bar.

  According to the present invention, the training using the barbell can be performed safely with a simple structure, and the user can practice in a form close to that of the actual competition. There is an effect that an equivalent operation can be performed safely.

  An embodiment of a training machine according to the present invention will be described with reference to examples shown in the drawings. The training machine shown in the drawings as an embodiment of the present invention is merely an example, and the present invention is not limited to the illustrated apparatus. The present invention can be applied to various equivalent apparatuses. .

<Example 1>
A first embodiment of the present invention will be described with reference to FIGS. 1 is a perspective view conceptually showing a first embodiment of a training machine according to the present invention, FIG. 2 is a rear view thereof, FIG. 3 is a sectional side view, and FIG. 4 is a plan view. In FIG. 4, the illustration of a load disk and the like is omitted.

  The training machine according to the present invention is a training machine that performs an exercise of lifting and lifting loads such as weight lifting, power lifting, and the like, and mainly includes a support frame 1 and a base end side in the vertical direction ( In FIG. 4, the pair of arm-like bodies 2 and 2 supported so as to be rotatable in a direction perpendicular to the paper surface, a long connecting member 3 for connecting the arm-like bodies 2 and 2, and a rod 4 The cylinder 6 that can be protruded upward from the casing 5 and that can be immersed in the casing 5 and that operates with hydraulic pressure or pneumatic pressure, and the disks 7 and 7 that serve as loads can be attached to both ends, and the arm-like body 2 2 and a bar 8 supported at both ends. If a disk 7 or the like is attached to the bar 8, it is configured as a so-called barbell. Depending on the contents of the training, there may be a case where only the bar 8 is used, and the present invention allows such usage.

  The cylinder 6 supports the lower end of the casing 5 by being attached to the support frame 1 so as to be pivotable in the vertical direction (support point 5a), and the rod 4 is located at the center position in the width direction of the pair of arm-like bodies 2 and 2 and is arm-shaped. The body 6 is attached slightly on the front side (the disk 7 or the bar 8 side) of the attachment position of the body 2 to the connecting member 3 (attachment point 5b), and the cylinder 6 is rotatable in the vertical direction around the support position 5a. .

  A buffering valve 9 that allows the liquid or gas existing inside the casing 5 of the cylinder 6 to freely pass through or restricts the passage amount is connected by piping.

  Although the valve 9 is not shown in FIGS. 1 to 4, as shown in FIG. 5, for example, a flow control valve, for example, a throttle check valve is suitable. When the arm-like bodies 2 and 2 are rotated upward, that is, when the user lifts the barbell, the rod 4 protrudes from the casing 5, in other words, the action of the liquid or gas for performing such an operation. When the arm-like body 2 rotates downward, the resistance of the rod 4 moves into the casing 5, that is, the liquid or gas is squeezed so that it does not move smoothly in the casing 5. This is a means for buffering the descending speed of the arm-like body 2.

  Further, a load connecting means is attached to the tip of the arm-like body 2 so as to be rotatable in the vertical direction. The bar 8 is attached to the load connecting means. The load connecting means includes a second arm-like body 10 having a base end attached to the arm-like body 2 so as to be rotatable in the vertical direction. The bar 8 is configured to be attached to the free end of the arm-like body 10.

  As shown in the figure, the second arm-like body 10 is provided with a projection 10a provided so as to project in an orthogonal direction to an arm-like member and is pivotally supported at the tip of the arm-like body 2 so as to be rotatable in the vertical direction. In the figure, reference numeral 11 denotes a connection member for attaching the second arm-like body 10 to the arm-like body 2.

  In the first embodiment, the pair of arm bodies 2 and 2 are positioned with the support frame 1 interposed therebetween, and the support frame 1 is a wide box-shaped frame body as shown in the figure. The width dimension between the arm-like bodies 2 and 2 is substantially equal to the distance (internal dimension) between the pair of disks attached to the bar 8.

  By adopting such a configuration, not only the arm-shaped body 11 is rotated in the vertical direction, but also the second arm-shaped body 11 is rotated in the vertical direction so that the complicated operation of the user can be achieved. Accordingly, an action corresponding to a delicate movement as shown in FIG. 8, particularly a fine movement in the front-rear direction of the user's body (also the front-rear direction with respect to the support frame 1) is exhibited.

<Example 2>
A second embodiment of the present invention is shown in FIGS. FIG. 6 is a perspective view conceptually showing a second embodiment of the training machine according to the present invention, and FIG. 7 is a rear view thereof.

  The difference between the present embodiment and the first embodiment is the width dimension of the support frame 1. That is, the support frame 1 is a narrow columnar frame body as shown in the figure, and the width dimension of the support frame 1 is smaller than the width dimension between the pair of arm bodies 2 and 2 and the distance between the pair of loads attached to the bar. By adopting such a structure, the maximum load bearing value is reduced, but the cost can be reduced.
