Cross reference of related application

The present application is a continuation-in-part of U.S. Patent Application No. 14 / 793,680, filed July 7, 2015 entitled "Torsional Swivel Device ", incorporated herein by reference in its entirety and claims its benefits.

The present invention relates generally to exercise machines, and more particularly to a chest exercise machine for training muscles of the chest.

With the increased awareness of health problems caused by lack of exercise, the popularity of exercise machines has steadily increased. These machines can be designed with resilient components to provide a reaction force against the movement exerted by the user for exercise purposes. There is a chest movement machine with elastic components based on spring elements. However, these machines are complicated in structure, expensive to construct, and difficult to maintain and can be limited by heavy weight spring elements.

Therefore, it is necessary to provide a better chest movement machine.

The exercise machine may include a main shaft having a bottom end and an upper end along the longitudinal direction. The rotatable element may be provided at the bottom end of the main shaft. The rotatable element can rotate about an axis substantially transverse to the longitudinal direction. In one embodiment, the rotatable element can be positioned to roll back and forth across the surface. The handle bars may be attached to the main shaft at the upper end.

In one embodiment, the exercise machine may include a torsionally resilient assembly having a stationary torsion structure, a pivotable structure, and an elastic element. The pivotable structure may be pivoted about a torsional axis about a torsional axis. The elastic elements can be longitudinally arranged along a torsional axis substantially transverse to the longitudinal direction of the main shaft. The fixed torsion structure can be fixed to the main shaft. The pivotable structure may be pivoted to deform the resilient element to induce a resilient torque force.

In one embodiment, the exercise machine may include an engagement frame having a high end and a low end. The engagement frame can be rotatably mounted to the pivotable structure of the torsional elastic assembly through the high end portion. Additionally or alternatively, the engagement frame may be defined in angular relationship with the spindle about a torsional axis. The footrest can be rotatably secured to the engagement frame at the lower end. The user force applied through the handlebar and the footplate can cause a cloud of the spindle to change the angle relationship between the engagement frame and the spindle. Alteration of the angular relationship may cause the swivel structure to pivot to induce a resilient torque force for user motion.

Other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description and the accompanying drawings, which illustrate preferred structural embodiments incorporating the principles of the present invention by way of example only.

Reference in the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

Figure 1 is a perspective view illustrating an embodiment of a chest movement machine. The device 100 may include a major axis 101 having a bottom end 113 and an upper end along the longitudinal direction. The length of the main shaft 101 (or the height of the device 100) can be adjusted through the knob 113.

In one embodiment, a rotatable element 111, such as a wheel, ball, or other applicable rotatable mechanism, may be configured at the bottom end 113 of the spindle 101 to provide a rollable ground support for the device 100 have. For example, the rotatable element 111 may be positioned to roll back and forth across the surface along the direction between the front side and the back side of the device 100. The rotatable element 111 may be rotatably coupled to the main shaft 111 through a longitudinal axis of the main shaft 111 and / or an axis substantially transverse to the direction between the front side and the back side of the device 100.

The handle bars 105 may be attached to the upper end of the main shaft 101 on both sides of the device 100 through the coupling structure 115. The lateral direction between the two sides (e.g., the right and left sides) of the device 100 may define a sideway direction substantially transverse to the longitudinal direction of the main shaft 101. [ The rotational axis of the rotatable element 111 may be configured to be substantially parallel to the lateral direction of the device 100. [ The chest support 117 may be attached to the handle bars 105. The pin insert 119 may enable various angular configurations or modes of operation of the device 100, for example, between the handlebars 105 and the main shaft 101 to accommodate users of different heights. In some embodiments, the coupling structure 115 may define a plurality of insert holes for different angular configurations. The pin insert 119 may be disposed through one of the insert holes to select one of the angular configurations (or relationships) between the main shaft 101 and the handle bars 105.

The torsionally resilient assembly 107 is coupled to the spindle 101 between the upper end and the lower end 113 of the spindle 101 to provide a resilient torque force about the torsional axis through a pivotable structure (not shown) Lt; / RTI > The torsional elastic assembly 107 may comprise an elastic element (not shown) that substantially defines a torsional axis. The torque force can be induced as a result of deforming the elastic element caused by the pivoting motion of the swivel structure.

In one embodiment, the device 100 may include a containment frame 103 in which the high and low ends are arranged. The engagement frame 103 can be rotatably mounted to the pivotable structure of the torsional elastic assembly 107 through the high end such that the engagement frame 103 is pivoted about the torsional axis of the torsional elastic assembly 107 to the spindle 101 Thereby making it possible to turn around. The engagement frame 103 and the main shaft 101 may be defined in an angular relationship about the torsional axis of the torsional elasticity assembly 107 when not in motion (e.g., when there is no user motion).

The acceptance frame 103 may include two (or at least one) support bars 117 provided longitudinally between the high and low ends. The support bar 117 can be rotatably coupled with the pivotable structure of the torsional elastic assembly 107 at the high end. The scaffold 109 can be rotatably attached to each support bar 117 at the lower end of the engagement frame 103 to provide a user scaffold (or contact retention). For example, a user force applied through the handle bar 105 and the foot plate 109 may roll the main shaft 101 back and forth, thereby changing the angle relationship with the engagement frame 103. [ (E.g., a backward cloud to reduce the forward or relative angle to increase the relative angle) pivots the pivotable structure of the torsional resilient assembly 107 to provide a resilient torque force for user motion .

2 is a block diagram showing an embodiment of a chest movement machine. For example, the view 200 may be based on the device 100 of FIG. In one embodiment, the main shaft 101 may be telescopically configured with a plurality of sections including an upper section 201, a middle section 203, and a lower section 205. The spindle 101 may extend or shorten through the knob 113 selectively inserted into one of a plurality of engagement locations defined along the upper section 201.

The torsional elastic assembly 107 may include a pivotable structure 211, a fixed torsional structure 217, and an elastic element 209. The pivotable structure 211 can be pivotally coupled to the stationary torsion structure 217 about a torsional axis that is substantially longitudinally aligned with the resilient element 209. The fixed pivot structure 217 may be attached to the middle section 203 of the main shaft. The elastic element 209 may be configured such that the middle portion and the two end portions are longitudinally oriented.

The resilient element 209 may be received within the housing elements of the fixed pivot structure 217 and the pivotable structure 211. For example, the fixed pivot structure 217 may include a sleeve element to accommodate a middle portion of the resilient element 209. The pivotable structure 211 may include two (at least one) cap elements that individually receive the end portions of the elastic element 209. Each end portion of the resilient element 209 may be suitably encapsulated through the cap element of the pivotable structure 211.

The sleeve element and the cap element can be shaped to grasp (or match) the outer surface of the elastic element 209. For example, the cross-section of the outer surface of the resilient element 209 is not smoothly shaped (e.g., based on other applicable shapes having squarely, angularly, or resistively). The sleeve element and the cap elements can be defined to substantially conform to the outer surface of the non-smooth shape of the resilient element 209 to facilitate biting the resilient element for a resilient torque force.

According to some embodiments, the central passageway may be longitudinally defined through the elastic element 209. The pivot rod 213 can be received in the central passage of the resilient element 209 to guide the deformation of the resilient element 209. The torsional axis of the torsional elastic assembly may be defined along the pivot rod 213.

In one embodiment, the strength of the resilient torque force induced through the elastic element 209 depends on the level of pressure applied. For example, the resilient element 209 may be longitudinally compressed to increase the strength of the torque force induced by the same amount of angular movement between the pivotable structures 211 relative to the stationary torsion structure 217. The torsional elastic assembly may include a resilient adjustment control, such as a coupling screw 215, to configure the level of compression applied to the resilient element 209 to allow for a change in the strength of the resilient torque force.

Figures 3A-C illustrate exemplary configurations of a chest movement machine according to one embodiment of the present invention, such as the device 100 of Figure 1. As shown in FIG. 3A, the coupling structure 115 may define a plurality of insert holes 301, 303 to attach the handle bar 105 and the main shaft 101 in different angular relationships. FIG. 3A illustrates a configuration having a pin insert 119 disposed through an insert hole 303. FIG. FIG. 3B illustrates an alternative configuration with pin insert 119 disposed through insert hole 301. FIG. The handle bar 105 may be configured to be upwardly tilted, for example 30 degrees, relative to the support floor in Figure 3A. Alternatively or alternatively, the handle bar 105 in Figure 3B may be attached to the main shaft 101 in a manner substantially parallel to the support floor. 3C shows the upper section 201 and the handle bar 105 separated from each other.

Figures 4 and 5 are perspective views showing alternative embodiments of a chest movement machine. For example, the view 400 of FIG. 4 may be based on an alternative configuration of the device 100 of FIG. In the view 400, the handle bar 105 may be angularly configured at a large angle with the spindle 101 as compared with the view 100 of FIG.

Referring now to FIG. 5, device 500 may be configured similar to device 100 of FIG. For example, the device 500 includes a graft frame 503, a spindle 501, and a torsional elasticity assembly 507. The handle bar 505 can be configured to be coupled to the upper end of the main shaft 501. The upper section of the main shaft 501 is angularly different from the upper section of FIG. 2 to enable the bottom end of the main shaft 501 to tilt away from the footplate 509 in a resting state (or in a rest without user exertion) Shape.

6A and 6B illustrate examples of application of a chest movement machine according to one embodiment of the present invention, such as device 100 of FIG. Referring now to FIG. 6A, a perspective view 600 shows a user sitting on a chair facing forward with both hands on the handlebars 105 and placing both feet on the footplate 109 Respectively. The view 600A shows an angle 601 between the main shaft 501 and the supporting bar 207 (or the embracing frame) when the user is seated without exerting a forward pushing force through the handle bars 105 . Alternatively, the angle 601 may be determined by the user while the handlebar 105 is lifted (and / or the footplate 109 is pushed forward) such that the bottom end of the main shaft 501 rolls back, And the support bar 207, as shown in Fig. A resilient torque force through the torsional elastic assembly 107 may be generated to reset (e.g., open up) the pivot position between the spindle 501 and the support bar 207 again.

6B, the perspective view 600B shows the user push and / or foot plate 109 downward (or forward) through the handle bars 105 so that the bottom end of the main shaft 501 rolls forward The rearward pulling can be exemplified. The pivotal position between the main shaft 501 and the support bar 207 can be opened at an angle 606. [ A resilient torque force through the torsional elastic assembly 107 may be used to reset the pivotal position between the spindle 501 and the support bar 207 to cause the spindle 501 to roll back, closing down)).
