Description

[Technical field]

[0001] The present invention relates to the technical field of expanders, and more particularly to an expander fixing device and an expander to which the same is applied. [Background technology]

[0002] Nowadays, people are increasingly pursuing a healthier lifestyle. As a new generation of fitness product, the expander is lightweight and easy to carry, allowing people to train anytime and anywhere, and is well-liked by people.

[0003] Chinese patent (CN201920905356.8) discloses a fitness expander, which uses a motor as a force generating device, and combines the controllability of the traditional motor torque with an expander structure to enable the magnitude of the force generated to be changed according to the user's actual usage needs, making the user's fitness experience richer and more effective. Furthermore, the structure of the invention is lightweight and convenient to carry when traveling.

[0004] In the above solution, the outer end surface of the housing is provided with a buckle and / or a bolt hole for fixing to other equipment. The buckle is connected to a rope-like object, for example, by using a string. The bolt hole is used to directly fix the expander to an external object, for example, a wall, by a bolt. Summary of the Invention [Problem to be solved by the invention]

[0005] However, when actually using an expander for fitness or training, the expander needs to be fixed at different positions or different heights according to different training postures or actual usage scenarios. In particular, when trying to fix the expander through various gaps such as door gaps, the buckles and / or bolt holes of the above solutions make it difficult to fix the expander.

[0006] Furthermore, the above solutions and the conventional expander fixing devices cannot ensure that the fixing device of the expander is stably fixed at a certain point on the gap when the user exercises, and the fixing height of the expander cannot be conveniently changed.

[0007] Furthermore, it is not possible to ensure that the fixed point does not move as the user changes his / her training posture, which affects the expander's ability to be used anywhere and at any time, which is disadvantageous to its widespread use.

[0008] SUMMARY OF THE PRESENT DISCLOSURE In order to overcome the deficiencies of the prior art, the first objective of the present invention is to provide an expander fixing device, which can fix the expander in the gap and provide a stable fixing point for the expander for the user's training.

[0009] The second objective of the present invention is to provide an expander fixing device, which is provided with a locking member having at least one locking block, and the locking block can stably lock the expander in various gaps such as door gaps, window gaps, etc., and by installing different numbers of locking blocks, it can be suitable for different gap widths, and the solution is simple, practical, and ingenious.

[0010] The third objective of the present invention is to provide an expander fixing device, which is provided with a locking member and a fixing member, which are respectively arranged inside and outside the gap, forming a flexible and adjustable locking and clamping structure, which can fix the resistance band and the expander at different heights or different positions in the gap, and is suitable for trainees of different heights or different usage habits, and which has a simple structure, an ingenious concept, is easy to produce and manufacture, has low manufacturing costs, and is convenient for popularization and use.

[0011] As the fourth object of the invention, an expander is provided, and an expander fixing device is provided at one end of the expander, which fixes the expander in the gap and provides a stable fixing point for the expander, which is used for training the user. [Means for solving the problem]

[0012] In order to achieve one of the above objectives, the first technical solution of the present invention is as follows: An expander fixing device includes a resistance band, one end of the resistance band having a fixing member that allows the resistance band to pass in only one direction through a gap through which the fixing member cannot pass, and the other end of the resistance band having a connecting member for connecting to an expander, the resistance band having a locking member, the thickness of which is adjusted to adapt according to the width of the gap, thereby holding the fixing member fixed.

[0013] The expander fixing device provided by the present invention can stably fix the expander in various gaps such as door gaps, and can adapt to the width of various gaps by using a locking member to stably fix the fixing member at a certain point on the gap, so that it will not move during the user's training process and affect the use of the expander.

[0014] Furthermore, the locking member and fixing member of the present invention are used in cooperation to form a flexible and adjustable locking and clamping structure, which can fix the resistance band and expander at different heights or different positions in the gap to suit exercisers of different heights or different usage habits, and ensure that the fixing point does not move as the user's training posture changes, so that the expander can be used anytime and anywhere, with a simple structure, ingenious concept, easy to produce and manufacture, low manufacturing costs, and convenient for popularization and use.

[0015] As a preferred technical measure, the locking member is movably fitted to the resistance band, so that the distance between the fixing member and the locking member can be freely adjusted to suit different gaps, while the locking member can be slid on the resistance band to achieve the purpose of adjusting the thickness of the locking member.

[0016] As a preferred technical measure, the locking member includes a first elastic locking block and a second elastic locking block that are relatively movable. By arranging the first elastic locking block and the second elastic locking block that are freely slidable by the resistance band, the following options can be selected according to the width of the gap: 1, the first elastic locking block and the second elastic locking block are not used, that is, the fixing member can be stably fixed at a certain point on the gap only by the thickness of the resistance band itself; 2, the fixing member can be stably fixed at a certain point on the gap by using the first elastic locking block or the second elastic locking block; 3, the fixing member can be stably fixed at a certain point on the gap by using the first elastic locking block and the second elastic locking block simultaneously, which is suitable for use scenarios with a wide gap. Thus, the use scenarios of the expander are greatly expanded.

[0017] As a preferred technical measure, the first elastic locking block and the second elastic locking block have different thicknesses, so that the thickness variation of the combination of the first elastic locking block and the second elastic locking block is more uniform and suitable for more gap widths.

[0018] As a preferred technical measure, the surfaces of the first elastic locking block and the second elastic locking block are provided with uneven stripes, which can increase the surface friction of the first elastic locking block and the second elastic locking block, so that the first elastic locking block and the second elastic locking block are fixed more stably in the gap.

[0019] As a preferred technical measure, the fixing member is movably fitted to the resistance band, so that the resistance band and the fixing member can both be freely adjusted, which is convenient for use.

[0020] In order to achieve one of the above objectives, the second technical solution of the present invention is as follows: An expander fixation device, comprising: The resistance band includes a strip-shaped resistance band, and the resistance band is provided with a locking member that can abut against a certain gap wall surface, The locking member is provided with at least one locking block, whereby depending on the width of the gap, a different number of locking blocks are mounted on the locking member.

[0021] After continuous research and experimentation, the present invention provides a locking member having at least one locking block, and the locking block can stably restrict the position of the expander in various gaps such as door gaps, window gaps, etc., and by installing different numbers of locking blocks, it can be suitable for different gap widths, and the solution is simple, practical, and ingenious.

[0022] As suitable technical measures, A fixing member capable of contacting the wall surface of the gap is provided at one end of the resistance band, and a connecting member connected to the expander case is provided at the other end, the volume of the fixing member being larger than the volume of the connecting member, thereby allowing the resistance band to pass through gaps through which the fixing member cannot pass in only one direction.

[0023] The locking member and fixing member of the present invention are used in cooperation with each other and are arranged respectively inside and outside the gap, forming a flexible and adjustable locking and clamping structure that fixes the resistance band and expander at different heights in the gap and is suitable for exercisers of different heights or different usage habits, and has a simple structure, ingenious concept, easy to produce and manufacture, low manufacturing costs, and convenient for popularization and use.

[0024] The locking block is made from plastic, rubber, or wood and fits over the resistance band.

[0025] The fixing member has a columnar structure and is provided with a through hole for connecting the resistance band; The connecting member has an annular structure and is provided with a through hole for connecting the resistance band; The resistance bands pass through the through holes in the fixing member and extend to the through holes in the connecting member to form a circular interlocking structure, improving the structural strength of the expander while ensuring that the expander is subjected to more uniform forces.

[0026] As suitable technical measures, The locking block has a rectangular structure; Alternatively, the locking block has an arc-shaped structure, which reduces wear on the gap wall surface; Alternatively, the locking block may be of variable diameter construction to accommodate different gap widths.

[0027] In order to achieve one of the above objectives, the third technical solution of the present invention is: An expander comprising the expander fixation device described above.

[0028] When an exerciser uses the expander of this invention to perform fitness training, the expander of this invention can be fixed through various gaps, such as door gaps, according to different training postures, and the expander can be fixed at different points or different heights in the gaps according to actual needs. Furthermore, when the user exercises, the expander is stably fixed at a certain point on the gap, and the fixed point will not move with changes in the user's training posture. Furthermore, the expander of this invention can be used anytime and anywhere, which contributes to its popularization and provides a good user experience. Effect of the Invention
