Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a heightened folding rowing machine. Background Art

[0002] Foldable rowing machines are popular for their ease of storage and portability. These machines typically consist of two hinged sections, front and back, that fold and unfold using a rotating mechanism to accommodate various space requirements. Traditionally, to ensure stability during use, the front and back sections are designed with equal heights, while the seat is mounted on the back section, typically at a fixed height.

[0003] Some consumers with larger bodies or special preferences have expressed a desire to raise the seat height to enhance leg and back movement during rowing, thereby improving overall comfort. The traditional solution to this problem is to increase the height of the front and rear bases of existing rowing machines using extensions. However, this approach requires a large number of extensions, significantly increasing the size of the rowing machine when folded, making it more difficult to carry and store.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] In the prior art, a foldable rowing machine usually includes two parts, a front part and a rear part, which are rotatably connected so that the folding function can be achieved by rotation. The bases of the front and rear parts are usually the same height to maintain the stability of the rowing machine when in use. The seat is usually set on the rear part and the height is usually fixed. Some consumers have the need to increase the seat height to improve the comfort of use. The traditional practice is to add heightening components to the bases of the front and rear parts respectively, but this method will increase the height of the front half, and in order to ensure stability in use, more heightening components are required, which is not conducive to folding and storage.

[0040] In order to solve the above technical problems, this embodiment provides a heightened foldable rowing machine, please refer to Figures 1 to 4 As shown, Figure 1 This is a three-dimensional diagram of the elevated foldable rowing machine in the embodiment in use. Figure 2 This is a front view of the elevated foldable rowing machine in the embodiment when in use. Figure 3 This is a three-dimensional diagram of the elevated foldable rowing machine in the folded state in the embodiment. Figure 4 Schematic diagram of the connection component in use in the embodiment.

[0041] The heightened foldable rowing machine of this embodiment is as follows Figure 1 and Figure 2 As shown, it includes: a front frame 1, a reinforcement plate 2, a rear frame 3 and a connecting component 4.

[0042] The front frame 1 can be provided with a resistance device 5 as needed. The resistance device 5 is provided with a handle for the user to pull. The connecting end of the front frame 1 and the rear frame 3 is provided with a first inclined surface 11 facing upward.

[0043] The reinforcement plate 2 is fixedly connected to the top of the front frame 1, as shown Figure 4 As shown, a second inclined surface 21 facing upward is provided. The second inclined surface 21 is coplanar with the first inclined surface 11 , that is, the second inclined surface 21 is in the upward extension direction of the first inclined surface 11 .

[0044] The rear frame 3 is provided with a seat 6, and a heightening component 7 is provided at the bottom thereof. Figure 4 As shown, a third inclined surface 31 facing downward is provided at the connection end between the rear frame 3 and the front frame 1 .

[0045] Connecting component 4, such as Figure 3 and Figure 4 As shown, it includes a first rotating page 41, a second rotating page 42, a rotating shaft 43 and an inclined plate 44. The first rotating page 41 and the second rotating page 42 are connected by the rotating shaft 43 to form a hinge structure. The inclined plate 44 is fixedly connected to the first rotating page 41, the inclined plate 44 is fixedly connected to the rear frame 3 and is in contact with the third inclined surface 31. The second rotating page 42 is fixedly connected to the front frame 1.

[0046] Among them, when the elevated folding rowing machine is in use, Figure 4 As shown, the heightening member 7 and the front frame 1 are supported on the ground, the rear frame 3 and the reinforcing plate 2 are at the same height and their ends abut against each other, so as to restrict the rear frame 3 from rotating in the direction opposite to the folding direction, that is, restricting it from continuing to rotate in the unfolding direction and allowing it to rotate only in the folding direction. At this time, the inclined plate 44 is in contact with the first inclined surface 11 and the second inclined surface 21, so that the rear frame 3 is supported on the reinforcing plate 2 and the front frame 1 through the inclined plate 44.

[0047] The elevated foldable rowing machine of the above technical solution connects the front frame 1 and the rear frame 3 via a connecting assembly 4. The hinge structure enables the rotation and folding of the front and rear frames 3. Simultaneously, the height of the rear frame 3 is increased by a heightening component 7. The rear frame 3 is supported on the reinforcing plate 2 and the front frame 1 via an inclined plate 44, allowing the front frame 1 and the rear frame 3 to jointly support the user's weight when in use. The rear frame 3 aligns with the first inclined surface 11 and the second inclined surface 21 via the inclined plate 44, thereby enhancing its stability in conjunction with the front frame 1 and the reinforcing plate 2 during use. It can be seen that the elevated foldable rowing machine of the present invention only requires the addition of a reinforcing plate 2 and a connecting assembly 4, and the installation of a heightening component 7 on the rear frame 3 to increase the height of the seat 6 without increasing the height of the front frame 1. This effectively reduces the use of the heightening component 7 and its impact on the folding function.

[0048] In one embodiment of the above-mentioned rear frame 3 and the end portion of the reinforcing plate 2 abutting against each other, see Figure 3 and Figure 4 As shown, the connecting assembly 4 further includes a vertical plate 45 connected to the top of the inclined plate 44. The vertical plate 45 extends vertically and fits against the end of the rear frame 3. The end of the reinforcing plate 2 is provided with a vertically extending end surface, which fits against the vertical plate 45 in the use state. In this manner, the vertical plate 45 fits against the ends of the rear frame 3 and the reinforcing plate 2, respectively, which can further enhance the reliability and stability of the rear frame 3 and the reinforcing plate 2 when the ends are in contact with each other.

[0049] In another embodiment in which the ends of the rear frame 3 and the reinforcing plate 2 abut against each other, the ends of the rear frame 3 and the reinforcing plate 2 directly contact and abut against each other.

[0050] In order to further enhance the stability of the front frame 1 and the connecting assembly 4, and thus improve the stability of the connection between the front and rear frames 3, refer to Figure 3 As shown, the front frame 1 is provided with a fourth inclined surface 12 facing downward at the lower end of the first inclined surface 11 . In the use state, the fourth inclined surface 12 is in contact with the first rotating leaf 41 .

[0051] In one embodiment of the above-mentioned connection between the first rotating page 41 and the second rotating page 42 via the rotating shaft 43, see Figure 3 and Figure 4 As shown, the first rotating page 41 is provided with a first shaft sleeve 401 , the second rotating page 42 is provided with a second shaft sleeve 402 , and the rotating shaft 43 is sleeved between the first rotating page 41 and the second rotating page 42 to connect the first rotating page 41 and the second rotating page 42 .

[0052] In another embodiment in which the first rotating page 41 and the second rotating page 42 are connected via a shaft 43 , one of the first rotating page 41 and the second rotating page 42 is fixedly provided with a sleeve, and the other is provided with a shaft 43 , and the shaft 43 cooperates with the sleeve to achieve a rotatable connection.

[0053] In order to strengthen the structure of the inclined plate 44 and the connection strength between the inclined plate 44 and the rear frame 3, as shown in FIG. Figure 3 and Figure 4 As shown, a notch is provided in the middle of the inclined plate 44, and inner plates 46 are extended to the inner side of the rear frame 3 on both sides of the notch. The inner plate 46 is fixedly connected to the rear frame 3 and can be fixedly connected to the rear frame 3 together with the inclined plate 44, thereby improving the connection strength; the connecting assembly 4 also includes a handrail 47, which is fixed between the two inner plates 46. The handrail 47 can not only serve as a handrail when transporting products, but also be connected to the inner plate 46 into an integrated structure, thereby strengthening the structural strength of the inner plate 46 and the inclined plate 44, so that the structure of the connecting assembly 4 is more compact and firm.

[0054] In order to improve the firmness of the connection between the second rotating page 42 and the front frame 1, as shown in FIG. Figure 3 and Figure 4 As shown, the second rotating page 42 is horizontally arranged and fixedly connected to the bottom of the front frame 1. The connecting assembly 4 also includes a side plate 48 fixedly connected to the second rotating page 42. The side plate 48 is vertically arranged and fixedly connected to the reinforcing plate 2 and the inner side of the front frame 1 by bolts respectively.

[0055] In order to increase the firmness of the connection between the reinforcing plate 2 and the front frame 1, as shown in 5, Figure 5 for Figure 2 In the cross-sectional view of section A, a first bolt 8 and a second bolt 9 are respectively inserted into the interior of the front frame 1 and the reinforcement plate 2. The first bolt 8 is arranged horizontally and has a connecting hole 80 extending vertically therethrough. The second bolt 9 is arranged vertically and extends into the connecting hole 80, where it is threadedly connected to the first bolt 8. In this arrangement, the first bolt 8 and the second bolt 9 cooperate with each other to enhance the tensile and shear resistance of the reinforcement plate 2 and the front frame 1 in the horizontal and vertical directions, thereby improving the firmness of the connection.

[0056] For example, see Figure 5 As shown, the reinforcing plate 2 is provided with a transversely extending bolt hole 22 and a through-hole 23 vertically connected to the bolt hole 22. The second bolt 9 is disposed in the bolt hole 22, and its connecting hole 80 is opposite to the through-hole 23. The front frame 1 is provided with a vertically penetrating stepped hole 13. One end of the first bolt 8 abuts against the shoulder of the stepped hole 13, and the other end extends out of the front frame 1 and into the through-hole 23, where it is threadedly connected to the connecting hole 80.

[0057] Exemplarily, the first bolt 8 and the second bolt 9 can be swapped, that is, the first bolt 8 is set on the reinforcement plate 2, and the second bolt 9 is set on the front frame 1, and the reinforcement plate 2 and the front frame 1 are connected with reference to the above-mentioned matching method.

[0058] It is understandable that the first bolts 8 and the second bolts 9 may be provided in one, two or more groups in the length direction of the reinforcing plate 2 and the front frame 1 as required to ensure that the connection between the reinforcing plate 2 and the front frame 1 is sufficiently firm.

[0059] To improve product durability and reduce its own weight, the connecting component 4 is made of metal, such as stainless steel or aluminum alloy, to ensure connection strength, while the front frame 1, rear frame 3 and reinforcement plate 2 are made of wood to ensure structural strength while effectively reducing the weight of the product.

[0060] Illustratively, the first rotating page 41 and the side plate 48 are integrally formed, and the second rotating page 42 , the inclined plate 44 , the vertical plate 45 and the inner plate 46 are integrally formed.

[0061] It is understood that the elevated foldable rowing machine includes a folded state, and the front and rear frames are switched from the use state to the folded state by rotating around the rotation axis. For example, see Figure 3 As shown, in the folded state, the rear frame 3 is located at the bottom of the front frame 1 , and the heightening component 7 is in contact with the front frame 1 .

[0062] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
