Technical Field

[0001] The present invention relates to the technical field of sports equipment, and in particular to a treadmill shock-absorbing and buffering device with better efficiency, wherein a plurality of novel shock-absorbing blocks are arranged between a frame and a running board to effectively absorb the stepping gravity of the running board, reduce the vibration of the frame, and achieve the shock-absorbing and buffering effect of the running board. Background Art

[0002] The shock-absorbing structure of the prior art treadmill, such as Figure 1 , Figure 2 As shown, it is composed of a frame 1 in which a support plate 2 is provided, and a treadmill 3 is wound around the support plate 2. The athlete runs and steps on the treadmill 3. The inner side of the frame 1 is provided with a rubber material and elastic shock-absorbing block 5 by means of a plurality of bolts 4, and the shock-absorbing block 5 is made to support the support plate 2 upward to buffer the impact of the athlete's running and stepping, so as to achieve the effect of buffering and shock-absorbing. However, the above structure has the following disadvantages: (i) the shock-absorbing block 5 is in the shape of a solid straight cylinder, so the elasticity is poor and the force elasticity cannot be adjusted according to the weight of the athlete and the size of the running and stepping force. (ii) the direction in which the athlete runs and steps on the support plate 2 is not completely vertical downward, so that the shock-absorbing block 5 in the shape of a straight cylinder is easily distorted and becomes a curved straight cylinder in actual use, and the permanent deformation cannot be restored, resulting in poor buffering and shock-absorbing effect, and the shock-absorbing block 5 is easily damaged.

[0003] Therefore, how to develop a shock-absorbing structure that is different from traditional treadmills and has better cushioning and shock-absorbing effects is a goal that the relevant industry needs to work hard on. In view of this, the inventor thought of the idea of creation, and then used many years of experience to break through the design. After many discussions and sample tests and multiple production corrections and improvements, the present invention was launched. Summary of the invention

[0004] In view of the problems in the prior art of the shock-absorbing structure of the treadmill due to the straight-tube-shaped shock-absorbing block having lateral deflection and distortion, poor shock-absorbing effect and easy damage, the present invention provides a treadmill shock-absorbing and buffering device with better efficiency.

[0005] The present invention is implemented by the following scheme: The present invention provides a shock-absorbing and buffering device for a treadmill with better efficiency, comprising: a frame; a plurality of supporting members fixedly arranged at two sides inside the frame at intervals; a running board made of composite wood boards; a plurality of shock-absorbing blocks made of elastic plastic material and being quadrilateral hollow rings, which can define a top side, a bottom side, a left side, and a right side. The top side, bottom side, left side, and right side are connected to each other by a plurality of outer arc-shaped corners. A fixing hole is penetrated through each of the top side and the bottom side, and the cross-section of the ring wall is convex arc-shaped. The cross-section of the ring walls of the left side and the right side is concave arc-shaped. The bottom side is fixedly arranged on the top of each of the supporting members, and the top side is fixedly arranged and jointly supports the bottom of the running board upwards. When the running board is pressed down, the top side and the bottom side of the shock-absorbing block are compressed with each other. At the same time, the left side and the right side are extruded and expand outwards.

[0006] Through the technical solution provided by the present invention, the following technical effects are achieved: 1. When the shock-absorbing block is squeezed and deformed, the upper and lower sides and the left and right sides with opposite arc shapes can be used to evenly bear force, and with the elastic force of opposite bending, it can immediately and quickly rebound to the original normal state. Therefore, it is not easy to randomly deflect and twist under long-term repeated use, and has the advantage of extending the service life.

[0007] 2. When assembling the shock-absorbing block, the locking rod of the screwdriver can conveniently penetrate for screwing, making the structure of the shock-absorbing block have the convenience of assembly. Description of the Drawings

Detailed implementation manners

[0010] To further illustrate the embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0011] Now, the present invention will be further described in combination with the drawings and specific implementation manners.

[0012] First, as Figures 3 - 11 shown, the present invention provides a treadmill shock-absorbing and buffering device with better efficiency, including: A frame 10; A plurality of support members 20, fixedly arranged at intervals on both sides inside the frame 10; A running board 30, made of composite wood; A plurality of shock-absorbing blocks 40, made of elastic plastic material and in the shape of a quadrilateral hollow ring body 41, and capable of defining a top edge 411, a bottom edge 412, a left side 413, and a right side 414. The top edge 411, bottom edge 412, left side 413, and right side 414 are interconnected by a plurality of outer arc corners 415. A fixed hole 42 is provided through each of the top edge 411 and the bottom edge 412, and the cross-section of the ring wall is convex outward. The cross-section of the ring walls of the left side 413 and the right side 414 is concave inward. The bottom edge 414 is fixedly arranged on the top of each support member 20, and the top edge 411 is fixedly arranged and jointly supports the bottom of the running board 30 upward; when the running board 30 is pressed down, the top edge 411 and the bottom edge 412 of the shock-absorbing block 40 are compressed against each other. At the same time, the left side 413 and the right side 414 are squeezed and expand outward.

[0013] Among them, the diameter of the fixed hole 42 on the top side of the shock-absorbing block 40 is larger than the diameter of the fixed hole 42 on the bottom side.

[0014] With the structure of the above specific embodiments, the assembly and usage methods of the present invention are described as follows: (1). First, in actual implementation of the shock absorber block 40, the wall thickness A of the hollow ring body 41, the maximum outer diameter BB of the longitudinal section, the maximum outer diameter CC of the transverse section, and the axial length DD can be respectively set to 3.5 - 6.5 mm, 25 - 45 mm, 20 - 30 mm, and 20 - 30 mm. However, the above-mentioned dimensions are only for clearly describing a preferred embodiment of the present invention and cannot be used to limit the scope of implementation of the present invention, and can be adjusted according to customer requirements.

[0015] (2). When actually assembling all the shock absorber blocks 40, as Figure 11 shown, first pass the locking rod of a screwdriver 60 through the fixing hole 42 on the top edge 411 of the shock absorber block 40, and then screw-lock with a screw 61 one by one to fix the fixing hole 42 at the bottom edge 412 of the shock absorber block 40 to the top of the support member 20.

[0016] (3). Secondly, after all the shock absorber blocks 40 are assembled to the top of the support member 20, then cover the top of all the shock absorber blocks 40 with the running board 30 at the same time, and respectively screw-lock with a screw 62 and a U-shaped fixing piece 63 with a screw hole 64 one by one to fix the running board 30 to the fixing hole 42 at the top edge of each shock absorber block 40, and then the assembly between the running board 30, all the shock absorber blocks 40 and the support member 20 is completed.

[0017] (4). In addition, the following describes the test of a single shock absorber block 40 under different degrees of downward pressure as follows: (1). As Figure 8 shown, the running board 30 presses down with a force of 48 - 53 KG, and the shock absorber block 40 presents a reference appearance of being compressed by 5 mm.

[0018] (2). As Figure 9 shown, the running board 30 presses down with a force of 85 - 89 KG, and the shock absorber block 40 presents a reference appearance of being compressed by 10 mm.

[0019] (3). As Figure 10 shown, the running board 30 presses down with a force of 132 - 136 KG, and the shock absorber block 40 presents a reference appearance of being compressed by 15 mm.

[0020] With the structure of the above specific embodiments, the present invention can obtain the following beneficial effects: (1). First, as Figures 8 - 10As shown, when the user steps on the running board 30, the shock-absorbing block 40 is instantaneously pressed down by the upper running board 30 and is squeezed and deformed. It starts to be squeezed at the positions of the two fixing holes 42 in the center, and then gradually squeezes towards the two outer convex arc sides of the top edge 411 and the bottom edge 412, so that when being squeezed, the upper and lower sides can be evenly stressed and are not easily deflected or distorted. At the same time, the left side 413 and the right side 414 in the shape of an inner concave arc are also squeezed and expanded outwards on both sides, and the left and right sides are evenly stressed and are not easily deflected or distorted.

[0021] (2). Continuing the description in the previous paragraph (1), when the shock-absorbing block 40 is continuously squeezed and deformed by a greater downward pressure of the running board 30, at this time, until the running board 30 is pressed down more heavily as Figure 10 shown, for the top edge 411 and the bottom edge 412 in the shape of an outer convex arc, and the left side 413 and the right side 414 in the shape of an inner concave arc on the contrary, the shock-absorbing block 40 has an approximate rectangular shape, and the left side 413 and the right side 414 are also in a vertical straight line shape. At this time, the shock-absorbing block 40 has the maximum supporting force. At this time, the top edge 411, the bottom edge 412, the left side 413 and the right side 414 also all receive the maximum elastic force of opposite bending, and there is a reverse restoring force at the same time.

[0022] Therefore, when the user's foot instantaneously leaves the running board 30, and the downward pressure of the running board 30 instantaneously disappears, the top edge 411 and the bottom edge 412 of the shock-absorbing block 40 up and down, and the left side 413 and the right side 414 on both sides can immediately and quickly rebound to the original normal state due to the elasticity of the opposite arc bending, instead of being easily deformed under repeated use like the shock-absorbing blocks in the prior art with the same-direction arc (i.e., hollow circular) or straight cylinder shape. Therefore, the shock-absorbing block 40 of the present invention has better use elasticity and recovery efficiency under long-term repeated use, and has the advantage of extending the service life.

[0023] (3). When the customer needs to adjust the shock absorption effect of the running board 30, the number of assembled shock-absorbing blocks 40 can be adjusted and increased or decreased, or the plastic composition of the shock-absorbing block 40 can be adjusted to achieve different soft and hard degrees of elasticity.

[0024] (4). When actually assembling the shock-absorbing block 40, as Figure 11 shown, the locking rod of the screwdriver 60 and a screw 61 can pass through the fixing hole 42 with a larger hole diameter on the top side of the shock-absorbing block 40, and then it is convenient to screw the screw 61 into the fixing hole 42 on the bottom side of the shock-absorbing block 40 and the support member 20 at the same time, so that the structure of the shock-absorbing block 40 will not affect the assembly of the bottom side of the shock-absorbing block 40 and the support member 20 at all. Therefore, the present invention also has the convenience of assembly.

[0025] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined by the appended claims, and all such changes are within the scope of protection of the present invention.
