Description

Technical Field

[0001] This utility model belongs to the field of rowing machine technology, and in particular relates to a rowing machine with a convenient movable wooden track assembly. Background Technology

[0002] Currently, to improve user convenience and save home space, some rowing machines on the market are equipped with storage functions. For example, Chinese patent application number 202321307397.X discloses a rowing machine equipped with a self-locking component. This solution uses a wooden rail component that can slide against each other at the lower end of the rowing machine body to achieve the storage and unfolding operation of the whole machine by utilizing the relative sliding displacement between the components.

[0003] However, to ensure the stability of the rowing machine when in use and to prevent unexpected movement on the ground due to user movements or equipment vibrations, a rubber block (or other similar friction element) is usually fixed to the bottom of the wooden track assembly. This rubber block effectively increases the friction between the wooden track assembly and the ground, improving the anti-slip performance when the equipment is statically placed.

[0004] However, when storing or unfolding the device, the wooden track assembly needs to be slid along the ground. At this point, the rubber blocks, intended to prevent slippage, actually create significant and unstable sliding friction with the ground. This requires users to apply considerable pushing or pulling force to complete the sliding action, making the storage and unfolding process time-consuming and laborious. Utility Model Content

[0005] To address the shortcomings of existing technologies, a rowing device is provided that allows users to easily store and open the wooden track components.

[0006] This utility model is achieved by the following technical solution: a rowing device with a convenient movable wooden rail assembly, comprising a wooden rail assembly for supporting the rowing device, wherein the wooden rail assembly includes:

[0007] Fixed wooden rails;

[0008] A movable wooden rail, which slides in conjunction with the fixed wooden rail to allow the rail assembly to be stored or unfolded, and a seat cushion is mounted on the movable wooden rail; and

[0009] At least one pair of support components are provided at the lower end of the movable wooden rail. The support components include a support frame and a support part and a rolling part provided on the support frame. The rolling part includes a roller and an elastic element. The roller can undergo vertical elastic displacement under the action of the elastic element. When the movable wooden rail bears a set weight, the support part touches the ground. When the movable wooden rail is in an unloaded state, the preload of the elastic element causes the roller to touch the ground and the support part to be suspended.

[0010] During the unfolding and retraction of the wooden track assembly, the movable wooden track is in an unloaded state. Therefore, the rollers support the ground and support the movable wooden track, making it easy for the user to push or pull the movable wooden track to unfold or retract the assembly. When the user uses the rowing machine, they sit on the seat. At this time, the weight supported by the movable wooden track reaches the set value, and the support part touches the ground. Although the rollers also touch the ground, they do not bear any weight. In this situation, the movable wooden track is unlikely to slip, allowing for user operation.

[0011] The support section will be supported by any existing material with high friction, such as rubber.

[0012] Preferably, the support frame is provided with a downward-opening mating hole; the rolling part also includes a movable shaft extending into the mating hole; the movable shaft is provided with an abutting part that abuts against an elastic element, the elastic element being a compression spring, one end of the elastic element abutting against the inner end face of the mating hole, and the other end abutting against the abutting end of the movable shaft, thereby realizing the elastic displacement of the roller.

[0013] By providing mating holes on the support frame, and having the movable shaft connecting to the roller and the elastic element housed within these holes, the vertical displacement of the roller is limited, ensuring that the roller does not shift during rolling. The abutment portion of the movable shaft can be either a shoulder on the shaft or the elastic element directly abutting against the end face of the movable shaft.

[0014] Preferably, the support portion is integrally formed with the support frame; or

[0015] The support part is separately disposed from the support frame, and the support part is made of anti-slip material.

[0016] All of the above settings can ensure that the rowing machine will not slip when the user is using it.

[0017] Preferably, the upper end of the movable shaft is provided with a shoulder portion, which constitutes the abutment portion, and the elastic element is sleeved on the upper end of the movable shaft with the end of the elastic element abutting against the shoulder portion.

[0018] One end of the elastic element is fitted onto the movable shaft, and the end of the elastic element abuts against the shoulder of the shaft, which can enhance the stability of the elastic element.

[0019] Preferably, the inner end face of the mating hole is provided with a downwardly extending mating protrusion, and the upper end of the elastic element is sleeved on the mating protrusion.

[0020] The upper end of the elastic element is fitted onto the mating protrusion, and the upper end of the elastic element abuts against the inner end face of the mating hole, which can increase the stability of the elastic element.

[0021] Preferably, the movable shaft includes a movable shaft body and a mounting sleeve, wherein the movable shaft body and the elastic element abut against and slide with the mounting sleeve;

[0022] The movable shaft body is provided with a side opening and a mounting groove that is complementary to the shape of the mounting sleeve. The outer wall of the mounting sleeve is provided with an external thread structure, and the mating hole is provided with an internal thread structure that mates with the thread of the mounting sleeve. When the mounting sleeve is threadedly mated with the mating hole, the mounting sleeve can limit the downward movement of the movable shaft body to its extreme position.

[0023] The installation sleeve limits the movement of the movable shaft body, allowing it to move vertically under the action of the elastic element, but without disengaging from the mating hole.

[0024] Preferably, the mating hole has a smooth section with a smooth inner wall, and the outer wall of the movable shaft body contacts and slides with the smooth section.

[0025] The above settings can enhance the stability of the movable shaft body during vertical displacement.

[0026] Preferably, the mounting sleeve has a C-shaped cross-section, and when the mounting sleeve mates with the mounting groove, the mounting sleeve and the movable shaft body are coaxially arranged.

[0027] Preferably, the wall of the support frame is provided with a first locking hole that extends radially and communicates with the mating hole, and the wall of the mounting sleeve is provided with a second locking hole that extends radially corresponding to the first locking hole. The first locking hole and the second locking hole are fitted with locking components.

[0028] When the first locking hole and the second locking hole are aligned, the locking member passes through the first locking hole and the second locking hole to restrict the rotation of the mounting sleeve. At this time, the rolling direction of the roller is the sliding direction of the movable wooden rail.

[0029] By having the locking element pass through both the first and second locking holes simultaneously, the mounting sleeve can be prevented from rotating. This design prevents the mounting sleeve from coming loose. The mounting sleeve will abut against the circumferential end faces of the movable shaft body, thereby limiting the circumferential position of the movable shaft body and preventing the roller from deflecting, ensuring that the rolling direction of the roller is always the sliding direction of the movable wooden rail.

[0030] Preferably, the support component is located at the end of the movable wooden rail away from the fixed wooden rail.

[0031] The above settings can improve the support effect of the support components.

[0032] Compared with the prior art, the beneficial effects of this utility model are: by switching back and forth between the support part and the rolling part, the roller part bears the force and is supported on the ground when unloaded, which makes it convenient for users to push and pull the movable wooden rail to realize the storage or unfolding of the wooden rail assembly; when under load, that is, when the user is using it, the support part bears the force and is supported on the ground, which is stable and reliable, thereby preventing the movable wooden rail from slipping.

[0042] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0043] like Figure 1As shown, this embodiment discloses a rowing device with a convenient movable wooden rail assembly, including a wooden rail assembly for supporting the rowing device. The wooden rail assembly includes a fixed wooden rail 2 and a movable wooden rail 1, which are slidably engaged by a groove or rail. A seat cushion 11 is slidably mounted on the movable wooden rail 1 along its length. The fixed wooden rail 2 and the movable wooden rail 1 are locked together by a wooden rail locking device 4, which is used in any existing rowing device, to lock the movable wooden rail 1 and the fixed wooden rail 2 when they are folded up or unfolded.

[0044] The fixed wooden rail 2 is equipped with a rowing machine damping device 3. The rowing machine damping device 3 is any damping device that exists in existing rowing machines, such as damping devices including water resistance, magnetic resistance, coils, and wheels. A pair of support components 5 are provided on the lower side of the movable wooden rail 1 away from the fixed wooden rail 2. The support components 5 support the movable wooden rail 1 and are located on the inner side of the movable wooden rail 1.

[0045] like Figures 2 to 8 As shown, the support assembly 5 includes a support frame 51, a support part 7, and a rolling part 6. The support part 7 and the rolling part 6 are disposed on the support frame 51, which is fixed to the movable wooden rail 1 by screws. The support frame 51 and the support part 7 are separately disposed, with the support part 7 located at the lower end of the support frame 51. The support part 7 is an anti-slip pad, which can be an existing rubber block with a large coefficient of friction to prevent the movable wooden rail 1 from slipping.

[0046] Alternatively, in some other embodiments, the support part 7 and the support frame 51 are integrally formed. Typically, the support frame 51 is made of plastic material. When the support part 7 is supported on the ground, it can also achieve an anti-slip effect.

[0047] The rolling part 6 includes a roller frame 62, a roller 61 rotatably connected to the roller frame 62, a movable shaft 63 connected to the roller frame 62, and an elastic element 8 that realizes the vertical elastic displacement of the movable shaft 63. When the movable wooden rail 1 bears a set weight, the support part 7 bears the force and touches the ground; when the movable wooden rail 1 is in an unloaded state, the preload of the elastic element 8 causes the roller 61 to bear the force and touch the ground, and the support part 7 is suspended in the air.

[0048] The support frame 51 has a downward-opening mating hole 52. The movable shaft 63 extends into the mating hole 52. A downward-extending mating protrusion 523 is provided at the center of the upper inner end face of the mating hole 52. A shoulder 64 is provided at the upper end of the movable shaft 63. The elastic element 8 is a compression spring. The upper end of the elastic element 8 is sleeved on the mating protrusion 523 and abuts against the upper inner end face of the mating hole 52. The lower end of the elastic element 8 is sleeved on the upper end of the movable shaft 63 and abuts against the shoulder 64.

[0049] The movable shaft 63 includes a movable shaft body 631 and a mounting sleeve 633. The movable shaft body 631 is integrally formed with the roller frame 62. The upper end of the movable shaft body 631 is provided with the aforementioned shaft shoulder 64, which abuts against the elastic member 8. The mounting sleeve 633 has a C-shaped cross-section. The movable shaft body 631 is provided with a side-opening mounting groove 632 that is complementary in shape to the mounting sleeve 633.

[0050] The upper part of the mating hole 52 is a smooth section 521 with a smooth inner wall, and the lower part is a threaded section 522 with an internal thread structure on the inner wall. The outer wall of the movable shaft body 631 slides in fit with the smooth section 521, and the outer wall of the mounting sleeve 633 has an external thread structure. The mounting sleeve 633 is threaded in fit with the threaded section 522. When the mounting sleeve 633 is fitted with the mounting groove 632, the mounting sleeve 633 and the movable shaft body 631 are coaxially arranged, and the mounting sleeve 633 and the movable shaft body 631 can rotate synchronously along the axis of the movable shaft 63, so that the mounting sleeve 633 is screwed into the threaded section 522. Furthermore, after the mounting sleeve 633 is threaded in fit with the threaded section 522, when the movable shaft body 631 moves downward, the mounting sleeve 633 will abut against the lower end of the shoulder 64 of the movable shaft body 631, thereby limiting the extreme position of the downward movement of the movable shaft body 631.

[0051] like Figures 4 to 8 As shown, the wall of the support frame 51 is provided with a first locking hole 91 that extends radially and communicates with the mating hole 52. The wall of the mounting sleeve 633 is provided with a second locking hole 92 that extends radially corresponding to the first locking hole 91. The first locking hole 91 and the second locking hole 92 are fitted with locking elements (not shown in the figure); the locking elements can be pins or screws. When the mounting sleeve 633 is screwed into place with the threaded section 522, the first locking hole 91 and the second locking hole 92 are aligned. The locking elements pass through the first locking hole 91 and the second locking hole 92 to restrict the rotation of the mounting sleeve 633. The mounting sleeve 633 provides circumferential restraint to the movable shaft body 631 to restrict the entire movable shaft 63 from rotating along its own axis. At this time, the rolling direction of the roller 61 is the sliding direction of the movable wooden rail 1.

[0052] During the unfolding and retraction of the wooden track assembly, the movable wooden track 1 is in an unloaded state. Therefore, the rollers 61 are supported on the ground, making it easy for the user to push or pull the movable wooden track 1 to unfold or retract the wooden track assembly. When the user uses the rowing machine, the user sits on the seat 11. At this time, the weight borne by the movable wooden track 1 reaches the set value, and the support part 7 touches the ground. Although the rollers 61 also touch the ground, they do not bear any weight. At this time, the movable wooden track 1 is unlikely to slide, making it convenient for the user to use.
