Description

Technical Field

[0001] The present disclosure relates to the technical field of treadmills, and in particular to a folding frame assembly and a folding treadmill. Background Art

[0002] Folding treadmills have been widely adopted due to their advantages such as convenient storage and space saving when not in use. In the current prior art, in order to achieve the foldable treadmill, the front and rear running decks of the folding treadmill are connected by a hinge, thereby achieving the folding purpose. For example, an existing patent application (CN107773913B) discloses a running deck assembly and a treadmill, which includes a front running deck; a rear running deck, the front end of which abuts the rear end of the front running deck; a flexible layer laid on the upper surfaces of the front and rear running decks; and an annular running belt that is transmittably interposed between the front and rear running decks. The flexible layer is laid on the surfaces of the front and rear running decks by bonding. This patent application uses the flexible layer to achieve the folding of the front and rear running decks, but this method of bonding the flexible layer complicates the manufacturing process and increases production costs. Moreover, after repeated folding and use over a long period of time, the bonding strength between the flexible layer and the front and rear running decks will decrease, and there is a risk of relative movement between the front and rear running decks and the flexible layer, thereby affecting the normal use of the folding treadmill. Based on this, it is necessary to further improve the folding method of the current treadmill. Utility Model Content

DETAILED DESCRIPTION

[0048] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0049] According to one embodiment of the present disclosure, Figure 1-12 As shown, the utility model provides a folding frame assembly 1, comprising:

[0050] First folding frame 11;

[0051] A front running board 12 is connected to the first folding frame 11;

[0052] The second folding frame 13 has a front end surface that abuts against the rear end surface of the first folding frame 11;

[0053] The rear running board 14 is connected to the second folding frame 13;

[0054] The base 15 is disposed outside the connection position between the first folding frame 11 and the second folding frame 13 . The base 15 is configured to simultaneously fix and support the first folding frame 11 and the second folding frame 13 .

[0055] like Figure 1-7 As shown, there are two first folding frames 11 and second folding frames 13, which are arranged in parallel. The first folding frames 11 and the second folding frames 13 are connected by connecting rods. The first folding frames 11 and the second folding frames 13 are the skeleton structure of the entire treadmill, and play the role of installing the front and rear running boards, rollers, and drive components. The folding frame assembly 1 provided in the embodiment of the present disclosure directly abuts the end faces of the first folding frame 11 and the second folding frame 13, and then uses the base 15 to fix the first and second folding frames while supporting the first / second folding frames. When the two folding frames of the folding frame assembly 1 need to be folded, it is only necessary to remove the base 15 and stack the second folding frame 13 on the first folding frame 11. At the same time, the rear running board and the corresponding annular running belt are also folded on the first folding frame, thereby realizing the folding function of the folding frame assembly 1, as shown in FIG. Figure 12 shown.

[0056] Furthermore, since the first and second folding frames are simply joined along the length of the folding frame assembly 1, they do not require a hinged connection, saving manufacturing steps and production costs. The front and rear running boards do not need to be connected by a flexible layer as in the prior art. In this embodiment, the front and rear running boards are directly and rigidly connected to the first and second folding frames, increasing their strength and service life. The entire folding frame assembly 1 only requires a base 15 to support the first and second folding frames when in a flat position, providing strong support for forward and backward running. When folding, the base can be removed to complete the folding process, making it simple and convenient.

[0057] In one possible implementation, Figure 1-11 As shown, the base 15 includes,

[0058] The base body 151 is provided below the first folding frame 11 and the second folding frame 13 along the width direction of the folding frame assembly 1;

[0059] The limiting protrusions 152 are provided at both ends of the base body 151 . An accommodating groove 153 for accommodating and fixing the first folding frame 11 and the second folding frame 13 is formed at the connection position between the limiting protrusions 152 and the base body 151 .

[0060] like Figure 10-11 As shown, the base 15 is generally in a concave shape, the limiting protrusion 152 is protruded from the base body 151, and the accommodating groove 153 is formed at the connection position of the limiting protrusion 152 and the base body 151. Figure 10 As can be seen in the figure, the inner surface of the limiting protrusion 152 is coplanar with the outer surface of the accommodating groove 153. When the accommodating groove 153 accommodates the first folding frame 11 and the second folding frame 13, at least the bottom of the first / second folding frame should extend into the accommodating groove 153.

[0061] The receiving grooves 153 formed at both ends of the base 15 are used to support the first folding frame 11 and the second folding frame 13, and also play a role in fixing the first / second folding frame so that after the first / second folding frame is unfolded, the first folding frame and the second folding frame remain stable when the user exercises on the circular running belt. Figure 3-4As shown, when the accommodating groove 153 is fixed on the first / second folding frame, the inner surface of the limiting protrusion 152 abuts against the outer surfaces of the first folding frame and the second folding frame, and the inner surface of the accommodating groove abuts against the outer surfaces of the first folding frame and the second folding frame, so that the accommodating groove 153 has a certain squeezing force on the first folding frame and the second folding frame in the X direction, limiting the freedom of the first / second folding frame in the X direction. In addition, since the endless running belt is drivably sleeved on the front running board and the rear running board, and the rollers provided at both ends of the endless running belt and used to drive the endless running belt to move are fixedly connected to the first folding frame and the second folding frame, the provision of the endless running belt limits the freedom of the first / second folding frame in the Y direction, so that the formation of the accommodating groove can stably fix and support the first folding frame and the second folding frame.

[0062] For example, the base 15 is an integrally formed structure consisting of a limiting protrusion 152 and a base body 151 . The integral structure is simple and convenient to manufacture and has high strength.

[0063] For example, the receiving groove 153 is fixed on the first folding frame 11 and the second folding frame 13 .

[0064] The receiving groove 153 and the first / second folding frame are configured as a snap-fit connection. That is, when the first folding frame 11 and the second folding frame 13 need to be unfolded, the end surfaces of the first folding frame 11 and the second folding frame 13 are brought into contact and downward pressure is applied. This allows the first / second folding frame to be snap-fitted into the receiving groove 153, thereby securing and supporting the first / second folding frame. This fixing method is simple and convenient, and is easy to install and remove.

[0065] To ensure that the base 15 can retain the first / second folding frame after repeated disassembly and installation, a wear-resistant layer can be provided on the surface of the receiving groove 153. The wear-resistant layer can be made of materials such as rubber and plastic. The wear-resistant layer can increase the service life of the base while maintaining the compressive force on the first / second folding frame. Furthermore, a rough surface or an anti-slip layer can be provided on the surface of the wear-resistant layer. Both the rough surface and the anti-slip layer can increase the friction with the first / second folding frame, ensuring the stability of the first / second folding frame when laid flat.

[0066] In one embodiment, Figure 6 As shown, the folding frame assembly 1 also includes a foot pad assembly 16, and the foot pad assembly 16 includes,

[0067] A first connecting block 161 is provided below the first folding frame 11 and connected thereto;

[0068] The second connecting block 162 is provided below the second folding frame 13 and connected thereto, and the front end surface of the second connecting block 162 abuts against the rear end surface of the first connecting block 161;

[0069] The foot pad 163 for supporting on the ground is provided below the first connecting block 161 or the second connecting block 162 and connected thereto.

[0070] The foot pad assembly 16 can support the first folding frame 11 and the second folding frame 13, ensuring that the entire folding frame assembly 1 can be placed horizontally on the ground without tilting.

[0071] Therefore, in order to accommodate the foot pad assembly, the base 15 also includes,

[0072] A first accommodating cavity 154 for accommodating the first connecting block 161 and the second connecting block 162 . The first accommodating cavity 154 extends downward from the bottom of the accommodating groove 153 and is in communication with the accommodating groove 153 .

[0073] The second accommodating cavity 155 is used to accommodate the foot pad 163 . The second accommodating cavity 155 extends downward from the bottom of the first accommodating cavity 154 and passes through the base body 151 . The second accommodating cavity 155 is communicated with the first accommodating cavity 154 .

[0074] like Figure 10-11 As shown, a first accommodating cavity 154 is formed extending downward from the middle position of the accommodating groove 153. The first accommodating cavity 154 divides the accommodating groove 153 into two parts, front and back, for fixing and supporting the first folding frame 11 and the second folding frame 13. A second accommodating cavity 155 is extended downward from the middle position of the first accommodating cavity 154. The upper and lower ends of the second accommodating cavity 155 are open and the second accommodating cavity is used to accommodate the foot pad 163. Figure 10-11 As can be seen, the accommodating groove 153, the first accommodating cavity 154, and the second accommodating cavity 155 form a cavity structure with openings at both ends. Within this cavity structure, the first / second folding frame, the first / second connecting block, and the accommodating foot pad are secured and supported. The first / second folding frame is secured within the accommodating groove 153, and the bottom surface of the first / second folding frame abuts the bottom surface of the accommodating groove. The first / second connecting block is secured within the first accommodating cavity 154, and the bottom surface of the first / second connecting block abuts the first accommodating cavity. The inner wall of the first accommodating cavity abuts the outer surfaces of the first and second connecting blocks. The foot pad is accommodated in the second accommodating cavity 155, with a gap between them.

[0075] Furthermore, for example, the bottom surface of the foot pad 163 and the bottom surface of the base body 151 are on the same horizontal plane. Therefore, when the foot pad is supported on the ground, the base body 11 is also supported on the ground, which can ensure that the treadmill is more stable when working.

[0076] Alternatively, the bottom surface of the foot pad 163 is located below the bottom surface of the base body 151, that is, when the foot pad 163 is supported on the ground, the bottom surface of the base body 151 is a certain distance away from the ground. Because the setting of the foot pad 163 is sufficient to ensure the stability of the entire treadmill, the base body does not contact the ground, which makes it convenient for the foot pad to be randomly adjusted according to the ground conditions.

[0077] Furthermore, the contact positions of the first folding frame 11 and the second folding frame 13 are staggered with the contact positions of the first connecting block 161 and the second connecting block 162. Figure 6 As shown, the abutting position of the first / second connecting block is located behind the abutting position of the first / second folding frame, so that when the first / second folding frame, the first / second connecting block and the foot pad are accommodated in the cavity structure, the abutting position of the first / second folding frame is located on the first connecting block, so that the first connecting block can support the first / second folding frame, further enhancing the stability of the first / second folding frame at the folding position.

[0078] In one possible embodiment, the rear end surface of the front running board 12 and the front end surface of the rear running board 14 abut against each other;

[0079] Alternatively, a gap is left between the rear end surface of the front running board 12 and the front end surface of the rear running board 14 .

[0080] like Figure 13 As shown, when the adjacent end surfaces of the front and rear running boards are in contact, the gap problem between the front and rear running boards is solved. Of course, a certain gap can also be left between the front and rear running boards, and rollers can be set in the gap to support the annular running belt. Figure 1-7 As shown, a roller support frame is fixedly mounted on the first folding frame and the first connecting block, and a roller is mounted on the roller support frame. The roller is arranged in the gap and is used to support the endless running belt.

[0081] According to one embodiment of the present disclosure, Figure 14-15As shown, the present invention also provides a folding treadmill, including an annular running belt 2, and also including the folding frame assembly 1 of any one of the above-mentioned embodiments, wherein the annular running belt 2 is tactilely sleeved on the front running board 12 and the rear running board 14, and a gap is left between the annular running belt 2 and the base 15. The so-called "annular running belt is tactilely sleeved on the front running board and the rear running board" means: first, the annular running belt accommodates the front running board and the rear running board, and when in the original state without any external force, there is a gap between the annular running belt and the front running board and the rear running board, and there is no direct contact; second, the annular running belt can be transmitted around the front running board and the rear running board, that is, the annular running belt rotates around the front running board and the rear running board. Moreover, when the user steps on the annular running belt, the annular running belt will adaptively contact the front running board and the rear running board. The folding treadmill with the folding frame assembly 1 of the present application can achieve a foldable effect. There is a gap between the annular running belt 2 and the base 15. Specifically, as Figure 15 As shown, a certain gap is left between the lower half of the circular running belt and the upper surface of the base, so that the base does not interfere with the rotation of the circular running belt. The foldable treadmill of the present application has a base 15, which can ensure that the first and second folding frames are stably supported and fixed to the base, thereby improving the stability of the entire folding frame assembly when the user exercises on the circular running belt, thereby ensuring the stability of the entire treadmill.
