Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and more specifically, to a handle assembly for a rowing machine. Furthermore, this utility model also relates to a rowing machine including the aforementioned handle assembly. Background Technology

[0002] Rowing machines are commonly used fitness equipment, and their handles are mostly rod-shaped structures with a traction cable connected in the middle. When using a rowing machine, the user holds both ends of the handles and exerts force with both arms simultaneously, usually in a seated position. However, when the user is kneeling or exercising with one arm, the traction cable connection point is in the middle of the handles, making it difficult to achieve a good force exertion posture. This is not conducive to kneeling or single-arm training, reducing the applicable scenarios for rowing machines and limiting the types of exercise that can be done with them.

[0003] Furthermore, the repeated bending and deformation of the traction rope at the connection point during exercise accelerates the wear and tear of the traction rope.

[0004] In summary, how to solve the problems of users not being able to obtain a good force exertion posture and severe wear and tear on the traction rope connection point during exercise when using rowing machines for kneeling or unilateral arm training is a problem that urgently needs to be solved by those skilled in the art.

[0035] The handle assembly for rowing machines provided by this utility model has at least the following advantages compared with the prior art:

[0036] 1. By setting shaft holes at both ends of the handle, adapters can be set at either end of the handle and a traction rope can be connected through the adapter. When performing seated paddling training, connecting the traction rope to both ends of the handle ensures that both arms exert force simultaneously, resulting in a better force exertion posture. When performing kneeling or single-arm paddling training, only one end of the handle needs to be connected to the traction rope. The user holds the handle with both hands simultaneously, using the hand furthest from the traction rope connection point as a fulcrum, and exerts force with the other arm. Alternatively, both hands can be used as fulcrums, and the two arms can exert force alternately for paddling training, both of which can achieve a better force exertion posture.

[0037] 2. The adapter and handle can rotate relative to each other, and there is a non-zero included angle between the two ends of the adapter's axis. This reduces repeated bending of the traction rope at the connection point during use, thereby reducing wear on the traction rope and extending its service life.

[0038] The rowing device provided by this utility model includes the above-mentioned rowing device handle assembly and has the same beneficial effects. Attached Figure Description

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] The core of this utility model is to provide a handle assembly for a rowing machine, which is used for rowing training. By providing shaft holes at both ends of the handle, either end of the handle can be connected to a traction rope via an adapter, ensuring that the user can obtain a good force application posture during various training methods. Furthermore, the adapter and the handle can rotate relative to each other, thus preventing repeated bending of the traction rope at the connection point with the handle and reducing wear on the traction rope. Another core aspect of this utility model is to provide a rowing machine including the aforementioned handle assembly. This rowing machine has both a rowing handle and the paddle handle of this application. Both the rowing handle and the paddle handle are used for rowing training and have the same technical features, solving the same technical problems.

[0052] Please refer to Figure 1 A handle assembly for a rowing machine, used to connect a tow rope inside the rowing machine, comprising:

[0053] Handle 1;

[0054] The adapter 2 has a first end connected to one end of the handle 1 and a second end used for fixed connection with the traction rope. There is a non-zero included angle between the axis of the first end and the axis of the second end of the adapter 2.

[0055] At least one end of the handle is provided with an adapter 2.

[0056] The end of the handle 1 is provided with a shaft hole, and the adapter 2 is rotatably installed with the handle 1 through the bearing 21, and the bearing 21 is fixedly installed in the shaft hole.

[0057] like Figure 1As shown, shaft holes are provided at both ends of the handle 1. According to user needs, the adapter 2 is installed and the traction rope is connected at the appropriate end. For example, when performing seated training, the traction rope is connected to both ends of the handle 1 through the adapter 2. Therefore, the two ends of the handle 1 are balanced by force. When the user holds the handle 1 with both hands, both arms can exert force at the same time, resulting in a better force exertion posture.

[0058] When performing kneeling or single-arm paddling training, connect only one end of handle 1 to the traction rope via adapter 2. During training, use the hand furthest from the traction rope connection point as the fulcrum, and exert force with the other hand and corresponding arm, or use both hands as fulcrums and alternately exert force with both arms to simulate paddling motion. Both methods can achieve a better force exertion posture and provide good arm training results.

[0059] Meanwhile, the adapter 2 is connected to the end of the handle 1 via a bearing 21, allowing the adapter 2 and the handle 1 to rotate relative to each other. Combined with the fact that the first and second ends of the adapter 2 have a non-zero included angle, preferably an obtuse angle, the traction rope has less frictional contact with the adapter 2 and the handle 1 during use. At the same time, when the handle 1 rotates, the adapter 2 rotates relative to the handle 1, thereby reducing repeated bending at the connection point of the traction rope, thus reducing the wear of the traction rope, and ensuring the linear change of the resistance experienced by the handle 1, improving the user experience.

[0060] In some embodiments, the first end of the adapter 2 is a stepped shaft, and the end of the stepped shaft is provided with an external thread. The inner ring of the bearing 21 is coaxially fitted on the minor diameter portion of the stepped shaft, and the end of one end of the inner ring of the bearing 21 abuts against the shoulder of the stepped shaft, and the end of the other end of the inner ring of the bearing 21 abuts against the end of the nut that is engaged on the external thread.

[0061] like Figure 1 As shown, the first end of the adapter 2 limits the inner ring of the bearing 21 through the shoulder and the threaded nut, so as to prevent the bearing 21 from axially displacing from the adapter 2.

[0062] In some embodiments, the inner ring of the bearing 21 is directly abutted against by a shoulder at the first end of the adapter 2, and a retaining ring is provided on the outer circumferential surface of the first end for the other end of the inner ring of the bearing 21 to abut against. Alternatively, the inner ring of the bearing 21 is directly fixedly connected to the first end of the adapter 2 by welding, or the inner ring of the bearing 21 and the outer circumferential surface of the first end are installed by an interference fit. All of these methods can achieve the above-mentioned effects.

[0063] In some embodiments, the outer ring of the bearing 21 is fitted into the shaft hole, and the inner wall of the shaft hole is provided with a shaft retaining ring 11 for abutting against the end of the outer ring of the bearing 21.

[0064] The inner diameter of the shaft hole is larger than the outer diameter of the outer ring of the bearing 21. The outer ring of the bearing 21 is installed in the shaft hole with an interference fit or a transition fit. The bearing 21 is limited by the shaft retaining ring 11 to ensure the stability of the bearing 21 in the shaft hole and prevent the adapter 2 from separating from the handle 1.

[0065] In some embodiments, the outer ring of the bearing 21 is directly fixed to the shaft hole by welding, or the outer ring of the bearing 21 is installed with an interference fit to the inner wall of the shaft hole, which can also achieve the above-mentioned effect.

[0066] In some embodiments, the second end of the adapter 2 is provided with a ball head connector 3, which includes a ball head and a ball cage. The ball head is wrapped inside the ball cage and can rotate in any direction inside the ball cage. The ball head is fixedly installed to the second end of the adapter 2, and the ball cage is used to be fixedly connected to the traction rope.

[0067] There is a non-zero included angle between the axis of the second end of the adapter 2 and the axis of the ball cage.

[0068] like Figure 1 As shown, the ball head connector 3 includes a ball head and a ball cage, which can rotate relative to each other in a spherical shape. The ball head is fixed to the second end of the adapter 2, and the traction rope is fixedly connected to the ball cage. When the user holds the handle 1 for training, the angle between the traction rope and the handle 1 changes. This angle change can be offset by the relative rotation between the ball head and the ball cage, thereby reducing the bending of the traction rope and reducing the wear of the traction rope.

[0069] Meanwhile, the ball cage is equipped with an extension shaft, and the traction rope is connected to the shaft end of the extension shaft. The axis of the extension shaft and the axis of the second end of the adapter 2 have a non-zero angle, which can reduce the wear between the traction rope and the adapter 2 during movement. At the same time, in conjunction with the non-zero angle between the axes of the first and second ends of the adapter 2, the lever arm between the connection point of the traction rope and the bearing 21 is effectively increased, so that the traction rope can drive the adapter 2 to rotate more smoothly. This effectively avoids the traction rope from applying rotational force to the handle 1, preventing the handle 1 from rotating in the user's hand and improving the user experience.

[0070] In some embodiments, the second end of the adapter 2 is a stepped shaft, and the end of the stepped shaft is provided with an external thread. The ball head is coaxially fitted onto the small diameter portion of the stepped shaft, and one end of the ball head abuts against the shoulder of the stepped shaft, while the other end of the ball head abuts against the end of the nut that is engaged on the external thread.

[0071] like Figure 1 As shown, the second end structure of the adapter 2 is the same as the first end structure. Both adopt a stepped shaft and an external thread at the end. The ball head is limited by the shoulder and the threaded nut to prevent the ball head connector 3 from disengaging from the adapter 2.

[0072] In some embodiments, the ball head is directly fixed to the second end of the adapter 2 by welding, which can achieve the same effect.

[0073] In some embodiments, the ball cage portion of the ball joint 3 or the second end of the adapter 2 is connected to the traction rope via a quick-release structure.

[0074] The traction rope is connected to the ball joint 3 or the adapter 2 via a quick-release structure. Adapters 2 and / or ball joints 3 are provided at both ends of the handle 1. Depending on the training needs, the end of the handle 1 to connect the traction rope can be selected. When the traction rope needs to be connected, the traction rope can be disconnected from the corresponding connection position simply by using the quick-release structure. No changes need to be made to the handle 1 or other connecting parts, and the training method applicable to the handle 1 can be quickly changed.

[0075] In some embodiments, the quick-release structure includes a quick-release pin shaft 5 and a quick-release pin connector 4;

[0076] The fixed end of the quick-release pin 5 is coaxially and fixedly connected to the ball cage section;

[0077] The quick-connect pin connector 4 is fixedly connected to the traction rope, and the quick-connect pin connector 4 is provided with a locking mechanism for the quick-connect pin shaft 5 to be inserted and quickly locked or released.

[0078] like Figure 1 As shown, the quick-release pin shaft 5 is coaxially fixedly connected to the extension shaft of the ball cage. If an internal threaded hole is coaxially provided in the extension shaft, the fixed end of the quick-release pin shaft 5 is coaxially fixedly connected to the internal threaded hole through the thread, while the insertion end can be inserted into the quick-release pin connector 4. Under the action of the locking mechanism, quick locking is achieved. When it is necessary to disconnect the traction rope, the quick-release pin shaft 5 can be pulled out by simply operating the locking mechanism, thus separating the handle 1 from the traction rope.

[0079] In some embodiments, an annular groove is provided on the outer periphery of the insertion end of the quick-connect pin 5;

[0080] The locking mechanism includes several sets of locking elements that can be engaged in the annular groove and a drive component that drives the locking elements to move radially along the quick-release pin shaft 5.

[0081] like Figure 1 As shown, an annular groove is provided on the outer periphery of the insertion end of the quick-release pin 5. When the insertion end of the quick-release pin 5 is inserted into the locking mechanism, the driving component in the locking mechanism can drive the locking element to engage in the annular groove, thereby preventing the quick-release pin 5 from disengaging from the locking mechanism. When disengagement is required, the driving mechanism reverses and drives the locking element to disengage from the annular groove, so that the quick-release pin 5 can be pulled out from the locking mechanism, thus realizing the disengagement of the traction rope.

[0082] In some embodiments, the quick-connect pin connector 4 includes an upper end seat 42 and a connecting body 43 that are coaxially slidably mounted, and an elastic element 45 is provided between the upper end seat 42 and the connecting body 43 along the relative movement direction;

[0083] The upper end seat 42 is a hollow structure, and a first guide groove 421 is provided on its outer peripheral wall. The length direction of the first guide groove 421 is perpendicular to the axis direction of the upper end seat 42.

[0084] The connecting body 43 is a hollow structure, and a second guide groove 431 is provided on its outer peripheral wall. The length direction of the second guide groove 431 has a non-zero angle with the axial direction of the connecting body 43.

[0085] A connecting pin 44 is simultaneously inserted into the first guide groove 421 and the second guide groove 431;

[0086] The quick-release pin 5 has an annular groove on the outer periphery of its insertion end. When the insertion end of the quick-release pin 5 is inserted into the hollow structure of the upper end seat 42, the connecting pin 44 can be engaged in the annular groove.

[0087] When the upper end seat 42 moves relative to the connecting body 43 in the direction of pulling out the quick-release pin shaft 5, the first guide groove 421 and the second guide groove 431 drive the connecting pin shaft 44 to move in the direction of engaging the annular groove.

[0088] When the upper end seat 42 moves relative to the connecting body 43 in the direction of insertion of the quick-release pin shaft 5, the first guide groove 421 and the second guide groove 431 drive the connecting pin shaft 44 to move in the direction of disengaging from the annular groove.

[0089] like Figure 2 , Figure 3 and Figure 4 As shown, two sets of inclined second guide grooves 431 are symmetrically arranged inside the connecting body 43, and a transverse first guide groove 421 is arranged inside the upper end seat 42. When the connecting pin 44 is simultaneously inserted into the first guide groove 421 and the second guide groove 431, the connecting pin 44 is at the overlapping position of the first guide groove 421 and the second guide groove 431. When the upper end seat 42 and the connecting body 43 move axially, the overlapping position of the first guide groove 421 and the second guide groove 431 changes, that is, the relative position of the connecting pin 44 with the connecting body 43 or the upper end seat 42 changes. Specifically, the connecting pin 44 is displaced radially along the upper end seat 42 or the connecting body 43.

[0090] like Figure 3As shown, the two sets of second guide grooves 431 are arranged in a figure-eight shape. When the upper end seat 42 and the connecting body 43 are relatively far apart, when the two connecting pins 44 move upward under the action of the first guide groove 421, the distance between the two connecting pins 44 becomes smaller due to the restriction of the second guide groove 431. At this time, when the quick-connect pin 5 is inserted, the two connecting pins 44 can be engaged in the annular groove, thereby restricting the relative axial movement of the quick-connect pin 5 and the quick-connect pin connector 4.

[0091] When the upper end seat 42 and the connecting body 43 are relatively close, the two connecting pins 44 move downward under the action of the first guide groove 421. Restricted by the second guide groove 431, the distance between the two connecting pins 44 increases, that is, the connecting pins 44 can disengage from the annular groove. At this time, the quick-release pin 5 can be pulled out from the quick-release pin connector 4.

[0092] The elastic element 45 between the connector 43 and the upper seat 42 keeps the connector 43 and the upper seat 42 relatively far apart in the default state. Therefore, the quick-release pin connector 4 is in a normally locked state. When quick release is required, simply press down on the upper seat 42 to bring the upper seat 42 closer to the connector 43.

[0093] In some embodiments, the quick-connect pin 4 also includes a lower end seat 41, which is fixedly connected to the traction rope;

[0094] The lower end seat 41 is coaxially and fixedly connected to the connecting body 43, and a baffle 411 is provided inside the lower end seat 41. The two ends of the connecting pin 44 respectively abut against the inner wall of the baffle 411 at the corresponding position.

[0095] The lower end seat 41 has a sliding groove on its outer periphery along its own axis, and the upper end seat 42 has a guide block 422 that is slidably installed in the sliding groove.

[0096] like Figure 2 and Figure 4 As shown, a lower end seat 41 is added to wrap the connecting body 43. A baffle 411 is used to shield the outer periphery of the first guide groove 421 and the second guide groove 431, thereby effectively preventing the connecting pin 44 from moving axially and disengaging from it. At the same time, in order to prevent the connecting body 43 from rotating with the lower end seat 41, a limiting groove 432 is provided at the end of the connecting body 43, and a limiting block is provided in the lower end seat 41 to engage with the limiting groove 432, so that the lower end seat 41 and the connecting body 43 will not rotate relative to each other.

[0097] Meanwhile, a through hole is provided on the outer periphery of the lower end seat 41, and a threaded hole is provided at the corresponding position of the connecting body 43. The connecting screw 46 passes through the through hole on the side wall of the lower end seat 41 and connects with the threaded hole of the connecting body 43, thereby restricting the axial movement of the connecting body 43 and the lower end seat 41.

[0098] Furthermore, a sliding groove is provided in the lower end seat 41 along its own axis, and a guide block 422 is provided in the upper end seat 42 that is slidably installed with the sliding groove, so as to prevent the upper end seat 42 from rotating relative to the lower end seat 41 and the connecting body 43, that is, to ensure that the upper end seat 42 and the connecting body 43 can only undergo axial displacement, thereby ensuring the working stability of the quick-release structure.

[0099] like Figure 3 As shown, a rope hole 412 is provided at the end of the lower end seat 41. After the traction rope passes through the rope hole 412, it can be fixed in the lower end seat 41 by tying a knot, so as to achieve connection with the quick-connect pin connector 4.

[0100] In some embodiments, the insertion end of the quick-connect pin 5 is tapered, and the connecting pin 44 is cylindrical. When the quick-connect pin 5 is inserted, it can force the connecting pin 44 to move radially until the insertion end of the quick-connect pin 5 is inserted. The connecting pin 44 then resets and locks into the annular groove, thus achieving automatic locking of the quick-connect pin 5.

[0101] In addition to the rowing machine handle assembly disclosed in the above embodiments, this utility model also provides a rowing machine including the above-mentioned rowing machine handle assembly.
