Patent Description:
As the living standard rises day by day, and people start to put more and more emphasis on physical health, exercise has become a very important entertainment for modern people. However, due to the crowded environment and poor air quality of the urban area, people tend to exercise indoors, for example, using exercise devices in a gym to conduct weight training, to maintain physical health and fitness. A conventional exercise device includes a frame body, a pulling mechanism and a counterweight mechanism, the pulling mechanism and the counterweight mechanism are connected through the cooperation of a rope and a roller set. When a user grasps a pulling member of the pulling mechanism, s/he needs to overcome the weight set on the counterweight mechanism to pull the pulling member and to train.

Document <CIT> discloses a conventional exercise device according to the preamble of claim <NUM>, including: a frame with a weighting seat; multiple pulley assemblies; multiple operation assemblies disposed on the frame each including two connecting members and at least one cable.

The conventional exercise device has just a single function, so the exercise device can only be used to train a specific muscle group. When the user wants to train other muscle groups, s/he needs to use other types of exercise devices, so it is inconvenient and costly.

The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.

The main object of the present invention is to provide an exercise device which is multi-functional to train different muscle groups and which can save the purchase cost and storage space.

To achieve the above and other objects, an exercise device according to claim <NUM> is provided, including: a frame, including a weighting seat which is movable, two first movable pulley assemblies and two second movable pulley assemblies; a first operation assembly, disposed on the frame, including two first connecting members and a first cable, the first cable curving back around one of the two first movable pulley assemblies, the weighting seat and the other of the two first movable pulley assemblies sequentially, the two first connecting members being connected to opposing ends of the first cable respectively; a second operation assembly, including two second connecting members and two second cables, each of the two second cables being connected to the frame and curving back around one of the two first movable pulley assemblies and one of the two second movable pulley assemblies, each of the two second connecting members being connected to an end of one of the two second cables; a third operation assembly, including two third connecting members and two third cables, each of the two third cables being connected to the frame and curving back around one of the two second movable pulley assemblies, each of the two third connecting members being connected to an end of one of the two third cables.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

Please refer to <FIG> for a preferable embodiment of the present invention. An exercise device of the present invention includes a frame <NUM>, a first operation assembly <NUM>, a second operation assembly <NUM> and a third operation assembly <NUM>.

The frame <NUM> includes a weighting seat <NUM> which is movable, two first movable pulley assemblies <NUM>, <NUM>' and two second movable pulley assemblies <NUM>, <NUM>'. In this embodiment, the weighting seat <NUM> is configured to carry at least one counterweight <NUM> to adjust the weight for exercising.

The first operation assembly <NUM> is disposed on the frame <NUM> and includes two first connecting members <NUM> and a first cable <NUM>. The first cable <NUM> curves back around one of the two first movable pulley assemblies <NUM>, the weighting seat <NUM> and the other of the two first movable pulley assemblies <NUM>'. The two first connecting members <NUM> are connected to opposing ends of the first cable <NUM>.

The second operation assembly <NUM> includes two second connecting members <NUM> and two second cables <NUM>. Each of the two second cables <NUM> is connected to the frame <NUM> and curves back around one of the two first movable pulley assemblies <NUM>, <NUM>' and one of the two second movable pulley assemblies <NUM>, <NUM>'. Each of the two second connecting members <NUM> is connected to an end of one of the two second cables <NUM>.

The third operation assembly <NUM> includes two third connecting members <NUM> and two third cables <NUM>. Each of the two third cables <NUM> is connected to the frame <NUM> and curves back around one of the two second movable pulley assemblies <NUM>, <NUM>'. Each of the two third connecting members <NUM> is connected to an end of one of the two third cables <NUM>.

Specifically, each of the two first connecting members <NUM>, the two second connecting members <NUM> and the two third connecting members <NUM> is configured to be connected to members such as grips, pull rings, drawstrings or other fitness members. As shown in <FIG>, when carrying out a first exercise, at least one of the two first connecting members <NUM> is pulled to drive the first cable <NUM>, the first cable <NUM> moves on the first movable pulley assembly <NUM>; since each of the two second cables <NUM> and each of the two third cables <NUM> are not driven to move, the first cable <NUM> moves relative to the weighting seat <NUM>, and the first movable pulley assembly <NUM> and the second movable pulley assembly <NUM> do not move relative to the frame <NUM>, so that the weighting seat <NUM> is driven by the first cable <NUM> to move upward relative to the frame <NUM>.

As shown in <FIG>, when carrying out a second exercise, one of the two second connecting members <NUM> is pulled to drive the second cable <NUM>, the second cable <NUM> moves on the second movable pulley assembly <NUM> and the first movable pulley assembly <NUM>; since the third cable <NUM> is not driven to move, the second movable pulley assembly <NUM> does not move relative to the frame <NUM>, the first movable pulley assembly <NUM> moves downward relative to the frame <NUM> and pulls the first cable <NUM>, so that the weighting seat <NUM> is driven by the first cable <NUM> to move upward relative to the frame <NUM>.

As shown in <FIG>, when carrying out a third exercise, one of the two third connecting members <NUM> is pulled to drive the third cable <NUM>, the third cable <NUM> moves on the second movable pulley assembly <NUM> and drives the second movable pulley assembly <NUM> to move upward relative to the frame <NUM>, and the second cable <NUM> is driven by the second movable pulley assembly <NUM> so that the second cable <NUM> drives the first movable pulley assembly <NUM> to move downward relative to the frame <NUM>, and thus the first movable pulley assembly <NUM> moves relative to the frame <NUM> to pull the first cable <NUM> so that the weighting seat <NUM> is driven by the first cable <NUM> to move upward relative to the frame <NUM>. In this embodiment, the first cable 22curves around at least two top posts <NUM> of the frame <NUM>.

Since the two first movable pulley assemblies <NUM>, <NUM>' and the two second movable pulley assemblies <NUM>, <NUM>' are symmetrically arranged and operated in the same way, the second movable pulley assembly <NUM>' is not described in detail. In addition to the first, second and third exercises, the user can choose from the three types of exercises for three regions of muscle of the body, and the three training modes can also provide users with single-hand or two-hand operations. As such, the exercise device provides plural training modes, so as to attract users to more incentives to use the exercise device, and also obtain the optimal training effects.

The two first movable pulley assemblies <NUM>, <NUM>' are located outside the frame, and the two second movable pulley assemblies <NUM>, <NUM>' are located inside the frame <NUM>. During the third exercise, the two first movable pulley assemblies <NUM>, <NUM>' move in a distance greater than a distance relative to the two second movable pulley assemblies <NUM>, <NUM>', so the two first movable pulley assemblies <NUM>, <NUM>' located outside the frame <NUM> can be prevented from interfering with other part(s) of the exercise device.

Therefore, through the exercise device the purpose of multi-functional training and training different muscle groups can be achieved, so it can save the purchase cost and storage space.

The frame <NUM> further includes two adjustment members <NUM> which are slidable, and the opposing ends of the first cable <NUM> are slidably connected to the two adjustment members <NUM> respectively so that each of the two first connecting members <NUM> is normally positioned to one of the two adjustment members <NUM>. Each of the two adjustment members <NUM> can be adjusted to be located in different heights to change the location of the first connecting member <NUM>. Preferably, an end of each of the two second cables <NUM> corresponding to the second connecting member <NUM> is connected to one of the two adjustment members <NUM>, as shown in <FIG>. As the adjustment member <NUM> moves relative to the frame <NUM>, the first cable <NUM> is driven; since the adjustment member <NUM> is connected to the second cable <NUM>, the second cable <NUM> is also driven so that the first movable pulley assembly <NUM> moves relative to the frame <NUM>. Through cooperation of the first cable <NUM> and the second cable <NUM>, the weighting seat <NUM> is not driven by the first cable <NUM> and does not move relative to the frame <NUM>, which is advantageous for adjusting the adjustment member <NUM>. In this embodiment, each of the two adjustment members <NUM> includes a support member <NUM> configured for supporting a barbell, to provide barbell training.

Specifically, the frame <NUM> defines a front end, a rear end, a left end and a right end, and the two first connecting members <NUM>, the two second connecting members <NUM> and the two third connecting members <NUM> are located at the front end of the frame.

In this embodiment, as viewed in a direction from the front end toward the rear end of the frame <NUM>, an end of each of the two second cables <NUM> to which one of the two second connecting members <NUM> is connected, sequentially, curves around at least one fixed pulley disposed on a bottom post <NUM> of the frame <NUM>, extends upward, curves inside out around the two second movable pulley assemblies <NUM>, extends upward, curves frontward around the two first movable pulley assemblies <NUM>, extends underneath the frame <NUM>, and extends upward, and another end of each of the two second cables <NUM> is connected to the frame <NUM>. As viewed in the direction from the front end toward the rear end of the frame <NUM>, an end of each of the two third cables <NUM> to which one of the two third connecting members <NUM> is connected, sequentially, curves around at least one fixed pulley disposed on a central post <NUM> of the frame <NUM>, extends downward, curves inside out around the two second movable pulley assemblies <NUM>, and extends upward, and another end of each of the two third cables <NUM> is connected to an upper portion of the frame <NUM>.

Preferably, each of the two first movable pulley assemblies <NUM> includes a first upper pulley <NUM> and a first lower pulley <NUM>, the first cable <NUM> curves around the first upper pulleys <NUM> of the two first movable pulley assemblies <NUM>, and each of the two second cables <NUM> curves around the first lower pulley <NUM> of one of the two first movable pulley assemblies <NUM>, so that the first cable <NUM> and the second cable <NUM> can move relative to the first movable pulley assembly <NUM> without interference. Preferably, each of the two second movable pulley assemblies <NUM> includes a second upper pulley <NUM> and a second lower pulley <NUM>, each of the two second cables <NUM> curves around the second lower pulley <NUM> of one of the two second movable pulley assemblies <NUM>, each of the two third cables <NUM> curves around the second upper pulley <NUM> of one of the two second movable pulley assemblies <NUM>, so that the second cable <NUM> and the third cable <NUM> can move relative to the second movable pulley assembly <NUM> without interference.
