Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of practicing the invention will occur to those skilled in the art and are within the scope of the invention.
The present invention provides a swing arm mechanism for exercise equipment that can be used to provide a gripping location for the handler or to provide support for the handler himself or a load bearing element (e.g., cable, etc.) operated by the handler. The swing arm mechanism is provided with a swing arm with an adjustable position so as to meet various position requirements required by training.
Figure 1 shows an exercise apparatus 1 having a swing arm mechanism 2. Fig. 2 shows a specific structure of the swing arm mechanism 2, which generally includes a base 10, a swing arm assembly 20, and a lock assembly 30. The base 10 on which the swing arm assembly 20 is mounted may be the base of the exercise apparatus 1 itself, or may be other structure independent of the exercise apparatus 1, such as a wall or the like. The base 10 is used to provide support for the swing arm assembly 20. According to the present invention, the swing arm assembly 20 is mounted on the base 10 by means of a linkage. The connecting rod transmission mode can enable the swing arm assembly 20 to stably move when the position is adjusted, noise generated by friction between parts is reduced, the structure is simple, the failure rate of the fitness equipment can be reduced, the service life can be prolonged, and maintenance is convenient. The locking assembly 30 may lock the swing arm assembly 20 in a desired predetermined position of the trainer when the swing arm assembly 20 is moved relative to the base 10 to that position.
With continued reference to fig. 1, as the exercise apparatus 1, in addition to the swing arm mechanism 2, it is preferable to further include a load element 40, an operation element (not shown), and a display screen 50. The load element 40 is used to provide the load required for training, and may be embodied as any device capable of providing resistance, such as an electric motor, a spring, or a weight. The load member 40 may be provided on the base 10 or may be separately installed from the base 10. The display screen 50 may be used to present a training tutorial or entertainment information to the trainer or to act as a mirror to facilitate the trainer observing corrective training actions. The operating element provides the point of strength for the training of the trainer, which can be a device such as a bracelet, a handle and the like, thereby increasing the diversity of the training modes. The operating element may be coupled to the load element 40 by, for example, a cable or a rope, and the load generated by the load element 40 is transmitted through the cable when operated. The operating elements may be attached to the swing arm assembly 20. The trainer can switch the training position by adjusting the position of the swing arm assembly 20 relative to the base 10. For example, the position adjustment of the swing arm assembly 20 may be a change thereof in the height direction with respect to the base 10. Of course, in some training modes, the position adjustment of the swing arm assembly 20 may also be a change in the horizontal direction, etc.
The specific structure of the swing arm mechanism 2 will be described in further detail with reference to the accompanying drawings.
In the illustrated embodiment, the swing arm assembly 20 includes a swing arm 21 and a mount 22. The swing arm assembly 20 is movably mounted to the base 10 by a mount 22, with a swing arm 21 extending outwardly from the mount 22. An operating element such as a bracelet or a handle may be attached to the swing arm 31, for example at the end of the swing arm 31, to facilitate operation by the trainer. Preferably, the swing arm 21 may be pivotably mounted with respect to the mount 22. In this way, the trainer can make fine adjustments to the position of the operating element by moving the swing arm 21. Preferably, the pivot axis of the swing arm 21 may be perpendicular to its own length direction. The positional relationship between the swing arm 21 and the mount 22 can be adjusted and fixed by a means such as a ratchet.
As shown in fig. 3, the linkage assembly for connecting the swing arm assembly 20 and the base 10 includes at least two links 11. Both ends of each link 11 are pivotably coupled with the base 10 and the mounting seat 22 of the swing arm assembly 20, respectively, so that the base 10, the mounting seat 22 and the link 11 therebetween together constitute a planar four-bar linkage. Preferably, the at least two connecting rods 11 are identical and arranged parallel to each other. The four-bar linkage is now effectively a parallelogram four-bar linkage. In this way, only the height and lateral distance of the mount 22 with respect to the base 10 are changed during the position adjustment, and the posture of the mount 22 itself is not changed, thereby achieving stable adjustment. Fig. 4 schematically shows three different positions of the swing arm assembly 20, an upper, higher training position, a lower, lower training position, and a storage position against the side of the base 10. It can be seen that in these three positions, the mount 22 remains in the same attitude at all times.
Preferably, the connecting rod assembly may comprise more than two connecting rods. Three links 11 are shown in figure 3. The additional connecting rods can enhance the connection strength between the mounting seat 22 and the base 10, and further improve the movement stability of the mounting seat 22 during the position adjustment process. It will be appreciated that the specific number of links may be flexibly selected by the skilled person during the design process, depending on factors such as the weight and length of the mounting. The parallelogram four-bar linkage mechanism is an exemplary preferred embodiment. In an alternative embodiment, when only two links are provided, the two links are not necessarily parallel. That is, the planar link structure formed by the base, the mounting seat and the link may also be a non-parallelogram four-link structure, as long as the height of the mounting seat (i.e., the swing arm assembly) can be adjusted by the link assembly.
Preferably, the link 11 may be pivotably coupled to the base 10 and/or the mount 22 by means of a joint bearing 12. The spherical plain bearing 12 can bear large axial and radial force and can perform centering motion within a certain angle. The swing arm assembly 20 thus maintains a smooth and even movement even when subjected to large loads during training.
As shown in fig. 4 and 5, the locking assembly 30 for locking the swing arm assembly 20 includes a first locking lever 31 and a second locking lever 32. Each locking lever is pivotably provided on the base 10. Wherein the first locking lever 31 corresponds to the upper training position shown in fig. 4, the second locking lever 32 corresponds to the lower training position and the storage position, and the position moving path of the swing arm assembly 20 is located between the two locking levers. The locking function will be described below by taking the first locking lever 31 as an example.
With continued reference to fig. 5, the first locking lever 31 is pivotally disposed on the base 10 about a first pivot axis AX 1. The first pivot axis AX1 is preferably offset relative to the pivot axis of the link 11 on the base 10. The first locking lever 31 is provided with a first stopper notch 311 opened at the lower side. Accordingly, the mount 22 of the swing arm assembly 20 is provided with a limit post 221 extending generally parallel to the pivot axis. When the mounting seat 22 moves with the connecting rod 11 to the upper training position as shown in fig. 4, the stopper column 221 can be snapped into the first stopper notch 311 (as shown in fig. 7).
In the illustrated embodiment, the retaining post 221 and the first retaining notch 311 are configured to secure the mounting block 22 in a self-locking manner. It will be appreciated that the mount 22 is moved relative to the base 10 by the link 11, whereby, in the plane of movement of the mount 22 (i.e. the plane perpendicular to the pivot axis of the link 11), the line between the link 11 and the pivot axis of the mount 22 and the base 10 respectively forms a radius of movement of the mount 22, and this radius of movement defines the path of movement of the mount 22. That is, the moving direction of the stopper rod 221 is necessarily perpendicular to the moving radius. In the upper training position, the radius of travel is shown as dashed line L2. Accordingly, no matter what load the swing arm assembly 20 is subjected to at this time, the moving direction thereof can be only in the direction of D2 or the direction of D2 which is perpendicular to the imaginary line L2. The radius of travel for the first locking bar 31 is shown as a dashed line L1. The moving direction of the first restriction notch 311 can be only in the direction of D1 or the direction of D1 perpendicular to the imaginary line L1. Obviously, D1 is oriented differently than D2. Further, the first locking lever 31 is configured such that the stopper column 221 abuts against the inner side edge of the first stopper notch 311 in the direction D2 or the reverse direction of D2. Thus, no matter what load the swing arm assembly 20 is subjected to, the stopper post 221 cannot actively escape from the first stopper notch 311. Only when the first locking lever 31 is actively moved to the disengaged position, the stopper pin 221 can be disengaged from the first stopper notch 311 and move with the connecting rod 11. This achieves a secure locking of the swing arm assembly 20 in the upper training position by means of a self-locking mechanism.
Fig. 8 shows the radius of movement (dotted line L4), the direction of movement (reverse of D4 or D4) of the mount 22, and the radius of movement (dotted line L3) and the direction of movement (reverse of D3 or D3) of the second stopper notch 321 of the second lock lever 32 when the mount 22 is in the lower training position. Similar to when in the upper training position, the direction of D3 is different from the direction of D4, and the second lock lever 32 is configured such that, in the direction of D4 or the reverse direction of D4, the stopper post 221 abuts against the inner side edge of the second stopper notch 321. Similarly, no matter what load the swing arm assembly 20 is subjected to, the stopper pin 221 cannot be actively disengaged from the second stopper notch 321, and only when the second locking lever 32 is actively moved to the disengaged position, the stopper pin 221 can be disengaged from the second stopper notch 321 and move with the connecting rod 11. Thereby securely locking the swing arm assembly 20 in the low exercise position in a self-locking manner.
It can be seen from figure 4 that when the swing arm assembly 20 is in the stowed position, it is actually lowermost in the path of travel and abuts the side of the base 10. The swing arm assembly 20 does not have any tendency to move in its natural state. Correspondingly, the second locking lever 32 corresponding to the lower training position is further provided with a receiving position notch 322 for receiving the limit post 221. The receiving notch 322 is located inside the second stopper notch 321 in the longitudinal direction of the second locking lever 32. Since the swing arm assembly 20 has no tendency to move, it does not need to be restrained. And the outer side edge of the receiving slot 322 has a larger inclination angle to facilitate the sliding of the stopper rod 221, so that the trainer can move the swing arm assembly 20 out of the receiving position by pulling the swing arm assembly to overcome the gravity thereof without operating the second locking rod 32.
Preferably, referring to fig. 6, taking the first locking rod 31 as an example, an extension section 312 is provided on a side of the first limiting notch 311 away from the base 10, and the extension section 312 protrudes into a moving path of the mounting seat 22. In adjusting the mount 22 to the high training position, the stop post 221 first contacts the lower side of the extension 312, slides along the lower side as the mount 22 continues to move upward, and snaps into the first stop notch 311 as the mount 22 moves to the high training position. This snapping action may provide a tactile and audible cue to the trainer to alert the swing arm assembly 20 of the adjustment in position. The extension 312 is provided to more easily align the stopping post 221 and the first stopping notch 311. The same structure may be provided to the second locking lever 32.
Preferably, the locking assembly 30 further includes a biasing member 34 for biasing the first and second locking levers 31 and 32 toward a direction in which the stopper post 221 is engaged with the stopper notch. This can reduce the risk of the lock lever undesirably moving in the direction of disengagement due to disturbance by an external force. In the illustrated embodiment, the biasing member 34 is configured as a spring. In further embodiments, the biasing member may also be a torsion spring, a solenoid, or the like.
Further preferably, the lock assembly 30 also includes an intermediate link 33 pivotally coupled with the first lock lever 31 via a third pivot axis AX3 and pivotally coupled with the second lock lever 32 via a fourth pivot axis AX 4. And preferably, the third pivot axis AX3 and the fourth pivot axis AX4 are located on either side of a line connecting the first pivot axis AX1 and the second pivot axis AX2, respectively, in a plane perpendicular to the pivot axes of the intermediate link 33. Thereby, the first locking lever 31 and the second locking lever 32 are formed into a link structure that can be interlocked to be opened and closed simultaneously. Only one of the two parts needs to be applied with force, so that the two parts can be operated. For example, only one biasing member 34 may be provided, that is, both may be biased in the direction in which the stopper column 221 engages with the stopper notch. When the swing arm assembly 20 needs to be unlocked, only one of the first locking lever 31 and the second locking lever 32 needs to apply a force, and the two can be moved towards the direction in which the limiting column 221 is separated from the limiting notch. Such a configuration can simplify the operation.
It will be appreciated that in other embodiments, the swing arm assembly may have more training positions of different heights. One locking rod can be respectively arranged to correspond to one training position, and a plurality of limiting notches (at least two) can be arranged on one locking rod at intervals, wherein each limiting notch corresponds to one training position.
Furthermore, although not shown in the drawings, the locking assembly may have other embodiments in accordance with the present invention. For example, a locking lever may be provided on one of the swing arm assembly and the base that can be extended in lateral translation, and a corresponding receptacle on the other. When the swing arm assembly is moved to a predetermined exercise position, the swing arm assembly is locked relative to the base by the locking bar extending into the receptacle. For example, a locking lever may be provided on the base that pivots about a vertical pivot axis, and when the swing arm assembly is moved to a predetermined exercise position, locking is achieved by the locking lever pivoting laterally to a position in which the swing arm assembly engages a corresponding mating structure on the swing arm assembly (e.g., the locking lever snaps into a slot in the lateral opening, etc.).
The foregoing description of various embodiments of the invention is provided for the purpose of illustration to one of ordinary skill in the relevant art. It is not intended that the invention be limited to a single disclosed embodiment. As above, many alternatives and variations of the present invention will be apparent to those of ordinary skill in the art. Thus, while some alternative embodiments are specifically described, other embodiments will be apparent to, or relatively easily developed by, those of ordinary skill in the art. The present invention is intended to embrace all such alternatives, modifications and variances of the present invention described herein, as well as other embodiments that fall within the spirit and scope of the present invention as described above.
