Description

  The present invention relates to the structure of a rock climbing machine, and more particularly, to a structure of a rock climbing machine that is strong and light in weight and easy to assemble and for personal or domestic rock climbing exercises. is there.

  At present, rock climbing exercises are flourishing, but there are few natural rock climbing places in the outdoors and there are safety problems when climbing. For this reason, an artificial rock climbing field has been developed, and the artificial rock climbing field is appropriately designed. Therefore, the safety is higher, but the space for installing the conventional artificial rock climbing field is large. The installation cost is high and the price is too high for general rock climbing users.

  A conventional rock climbing machine has a structure like a catapillar installed in the frame, and the catapillar structure is connected to a transmission mechanism to control the rotation speed of the catapillar structure. Note that both sides of the catapillar structure have link belts or rolling elements. Is installed in the rail of the frame body, so that the caterpillar structure circulates and rotates along the rail, and the caterpillar structure is provided with a number of locks, which allows the user to perform rock climbing (See Patent Document 1, Patent Document 2, or Patent Document 3).

  The catapillar structure of the various rock climbing machines described above is supported on both sides of the caterpillar and not supported at all in the middle part of the catapillar. To avoid this, the catapillar with the above structure is made very thick, otherwise it cannot withstand the weight of the user.

  For example, as disclosed in Patent Document 1, a large number of thick plates are fitted and connected to each other to form a caterpillar structure with one connecting element, and as disclosed in Patent Document 2, a large number of A metal frame is pivotally connected to each other, and a caterpillar structure is formed by fitting a plate into each metal frame. Also, as disclosed in Patent Document 3, a large number of extrusions are used. A caterpillar structure is formed by pivoting plates together. In order to avoid swinging or deformation of the catapillar, the catapillar of the above structure is made extremely thick, and the catapillar structure occupies most of the weight of the entire rock climbing machine, and the weight of the entire rock climbing machine is several hundred kilograms The mobile work is difficult, that is, the above-mentioned rock climbing machine is not suitable for a personal or home rock climbing exercise.

  In addition, the above-mentioned various rock climbing machines are designed to have a large and thick frame in order to support a heavy catapillar structure, which makes it difficult to assemble and transport, and makes a personal or home-like rock climbing exercise. Not suitable for.

  On the other hand, since all of the above-mentioned various rock climbing machines adopt a caterpillar structure, a gap is formed between the plate and the plate, and in particular, the gap becomes larger at the portion where the catapillar structure is folded. The gap may cause an unexpected accident with the user's hair or clothes in between.

  Therefore, the applicant of the present invention has proposed a rock climbing machine, and a rock climbing machine having a lighter structure is provided with a circulation rotation mechanism between two frames of the base, and the circulation rotation mechanism is circulated. There are a plurality of rotating link belts, each link belt is provided with a large number of lugs at an equal distance, a plurality of lateral rods are installed by the lugs, and each lateral rod has two ends at two ends. It is fitted in the opening of the frame, so that the transverse rod connected to each link belt can circulate and rotate at the inner edge of the opening of the two frames, and the link belt and the transverse rod A mud for covering each link belt and the lateral rod is provided on the outer surface, and a lock is fastened at a position corresponding to the lug on the outer surface of the mud, and each link is between two frames. Stop plate exhibiting a U-shaped corresponding to the belt is provided (see Patent Document 4).

  By installing a link belt that can rotate in rotation between the two frames, a lock can be installed, and the external force received by the lock is applied to the link belt, and multiple lateral rods are equidistant to the link belt. The two ends of each lateral rod are inserted into the opening of the frame, and a plurality of U-shaped bases with which each link belt abuts are provided between the two frames. The external force pulled inward and outward is absorbed, the circulation rotating device can be simplified, and the entire rock climbing machine can be reduced in weight.

  However, some drawbacks have been found in the above-mentioned rock climbing machine during the actual use process. The lock is fixed to the link belt, and when the lock receives an external force inward, the link belt contacts the U-shaped base with the link, and when the link belt circulates and rotates, wear and noise occur, When used for a long period of time, the link and U-shaped base will wear out, rotation will be unsatisfactory, the strength of the link belt will decrease, and when the lock receives external force to the outside, Both ends of the rod rub against the inside of the frame opening, and wear and noise are generated inside the transverse rod and the frame opening.

  Also, since the rock climbing machine is lighter, it can be used for a personal or home-use rock climbing machine, but the length of the frame is longer than the height of an adult, and the frame is divided into two parts. However, since it is difficult to combine the two parts, the rock climbing machine cannot be combined individually, and there is no support structure between the two frames, only the base at the bottom end. Therefore, the strength of the whole structure is insufficient.

  In addition, since each lateral plate of the rock climbing machine is installed at an equal distance, a gap is formed between the lateral plate and the lateral plate, and a mud covers the outer surface of the lateral plate. However, when climbing, the user erroneously contacts the gap and pushes the mud down, and the mud contacts the link belt or the frame in the frame and wears.

  In addition, the mud needs to maintain an appropriate tension, but the mud covers the outer surface of each lateral plate and is fixed to the link belt by a lock, and when the lateral plate is moved to the sprocket, The lateral plate touches the circumference of the sprocket. As shown in Fig. 12, both sides of the lateral plate pull the mud, and the pulled mud breaks at the place where the lock is fixed. When it becomes impossible to rotate and an elastic material is adopted for the mud, the inner surface of the mud is worn by contact with the link belt or the frame in the frame, and if used for a long time, the elasticity of the mud tends to decrease. .
