Description

Climbing machine structure

Technical Field

The present invention relates to a climbing machine, and more particularly to a climbing machine with a reduced height of a sliding rail.

Background

The climbing machine is a common sports equipment, a displaceable pedal and a handle are arranged on a vertical track, an operator steps on the pedal by means of two feet in turn, and the two hands grasp the handle, so that the two feet and the two hands reciprocate in a straight line state, and the effect of simulating rock climbing is achieved.

Examples of climbing machines include a climbing machine provided by chinese patent publication No. CN210205813U, and a column-type combined climbing exercise machine provided by US patent publication No. US10758776B 2.

In the CN210205813U patent, a connecting frame capable of moving up and down relative to the frame is provided, and a handle and a foot pedal are respectively provided on the connecting frame. Wherein, because handle and running-board set up on same link, in order to let the operator grasp the handle smoothly, step on the running-board and reciprocating motion, the link must be higher, and in order to keep the balance of climbing machine, the link must set up in the center of climbing machine for the link can shelter from operator's sight.

In the above-mentioned US10758776B2 patent, the handles and the pedals are also provided at both ends of the same column, and similarly to the above-mentioned CN210205813U patent, the column must be high, and there is a problem that the operator's vision is also shielded.

With the operator's view being obscured, for example, once the screen is to be installed on the climbing machine, the screen would be obstructed by the connection frame if the screen were to be installed on the side of the connection frame remote from the operator; if the screen is mounted on the side of the connector frame that is closer to the operator, the screen will be too close to the operator for the operator to see. Even if the screen is set sideways as in the aforementioned US10758776B2 patent, the operator must turn the head to see the screen, which is still inconvenient to use.

Referring to fig. 1 to 3, a first embodiment of the climbing machine according to the present invention is disclosed for an operator a to operate in a standing position (the operator a is shown with fig. 14), and the extending direction of the trunk of the body is defined as a height direction when the operator a operates the climbing machine in the standing position. The terms left and right, up and down, body width, near and far, and the like are referred to below with reference to the position of the operator a in the operating state.

The climbing machine structure comprises: a bracket 10, a first slide rail set 20, a second slide rail set 30, a first pedal 40, a second pedal 50, a first handle 60, a second handle 70, a transmission unit 80, a resistance unit 90 and a screen 100. The first pedal 40 and the first handle 60 are slidably disposed on the first sliding rail set 20, and the second pedal 50 and the second handle 70 are slidably disposed on the second sliding rail set 30.

The stand 10 comprises a column 101, a base 102 and a screen frame 103, wherein the column 101 extends obliquely along a Z direction (i.e. the height direction), the base 102 is disposed on an XY plane perpendicular to the Z direction, and the XY plane is jointly constructed by an X direction and a Y direction perpendicular to each other, wherein the X direction is the body width direction of the operator a. The screen frame 103 extends obliquely upward from the upright 101 in a direction away from the operator a. The bracket 10 defines a first side 104 on the left and a second side 105 on the right in the X direction.

The screen 100 is disposed on the screen frame 103, and the screen 100 corresponds to a position of a eyes of the operator a in the height direction. Since the screen frame 103 extends obliquely upward in a direction away from the operator a, the screen 100 can be kept at a proper distance from the operator a in addition to the eye position corresponding to the operator a, thereby reducing the eye load of the operator a.

Preferably, the base 102 is provided with two support rods 1021 in parallel in the Y direction, the support rods 1021 extend along the X direction, and the support rods 1021 may have different lengths and appearances according to the gravity center position of the climbing machine structure, so as to ensure the stability of the climbing machine structure and the operation safety of the operator a.

The first sliding rail set 20 and the second sliding rail set 30 are vertically arranged on the upright 101, and the first sliding rail set 20 and the second sliding rail set 30 are arranged on the upright 101 in parallel in the X direction, so that the first sliding rail set 20 is located on the first side 104, and the second sliding rail set 30 is located on the second side 105.

Preferably, the first sliding rail set 20 has a first top end 20a with the highest position in the height direction, the second sliding rail set 30 has a second top end 30a with the highest position in the height direction, the upright 101 has an upright top end 101a with the highest position in the height direction, and the first top end 20a, the second top end 30a and the upright top end 101a are all lower than the eye position of the operator a in the height direction.

In the present embodiment, the first sliding rail set 20 and the second sliding rail set 30 are respectively parallel to two sliding rails in the Y direction. The first sliding track set 20 includes a first proximal sliding track 201 near the operator a and a first distal sliding track 202 far from the operator a, and the second sliding track set 30 includes a second proximal sliding track 301 near the operator a and a second distal sliding track 302 far from the operator a. In the present embodiment, after the first distal rail 202 and the first proximal rail 201 are fixed to the upright 101, the upper end of the first distal rail 202 is slightly higher than the upper end of the first proximal rail 201 in the height direction, so the first top end 20a of the first rail set 20 refers to the upper end of the first distal rail 202; similarly, the upper end of the second distal slide rail 302 is slightly higher than the upper end of the second proximal slide rail 301 in the height direction, so the second top end 30a of the second slide rail set 30 refers to the upper end of the second distal slide rail 202.

Referring to fig. 1, 4 and 5, the transmission unit 80 is disposed on the first side 104 and the second side 105 of the bracket, and includes a first belt 801 and a second belt 802 that are coupled to each other. The first belt 801 and the second belt 802 are respectively located on the first side 104 and the second side 105, and the first belt 801 and the second belt 802 are both circularly disposed along the height direction and can rotate back and forth relative to the bracket 10.

In this embodiment, the first belt 801 includes a first distal section 8011 (please refer to fig. 14) away from the operator a, and a first proximal section 8012 adjacent to the operator a, wherein the first distal section 8011 and the first proximal section 8012 move in opposite directions; the second belt 802 includes a second distal section 8021 remote from the operator a and a second proximal section 8022 proximate to the operator a (the second proximal section 8022 is shown in fig. 6), the second distal section 8021 and the second proximal section 8022 also have opposite directions of movement.

Referring to fig. 4 to 6, the transmission unit 80 includes a first belt 803, a second belt 804, a third belt 805, a fourth belt 806 and a rotation shaft 807 in addition to the first belt 801 and the second belt 802.

The first pulley 803 is independently pivoted to the upper portion of the upright 101 at the first side 104, the second pulley 804 is fixed to the rotating shaft 807 at the first side 104, the rotating shaft 807 is pivoted to the lower portion of the upright 101, and the rotating shaft 807 can relatively rotate to the upright 101. The third pulley 805 is independently pivoted above the upright 101 at the second side 105, and the fourth pulley 806 is fixed to the shaft 807 at the second side 105. The first belt 801 circulates around the first pulley 803 and the second pulley 804, and the second belt 802 circulates around the third pulley 805 and the fourth pulley 806. Since the second pulley 804 and the fourth pulley 806 are fixed to the rotating shaft 807 together, the second pulley 804, the rotating shaft 807 and the fourth pulley 806 can rotate back and forth synchronously, thereby the first belt 801 and the second belt 802 also rotate back and forth synchronously with each other.

Referring to fig. 1, 7, 8 and 9, the first pedal 40 is provided with a first slider 401, and the first slider 401 is fixed to the first proximal section 8012 by a first connecting piece 402. The second pedal 50 is provided with a second slider 501, the second slider 501 being fixed to the second distal section 8021 by means of a second connecting piece 502. The first handle 60 is provided with a third slider 601, the third slider 601 being fixed to the first distal section 8011 by means of a third connecting piece 602. The second handle 70 is provided with a fourth slider 701, the fourth slider 701 being fixed to the first proximal section 8012 via a fourth connecting piece 702.

At least one roller 403, 503, 603, 703 is disposed on each of the first slider 401, the second slider 501, the third slider 601, and the fourth slider 701.

Referring to fig. 8 to 10, the rollers 403, 503, 603, 703 roll in the first sliding rail set 20 and the second sliding rail set 30, so that the first sliding block 401, the second sliding block 501, the third sliding block 601 and the fourth sliding block 701 slide relative to the first sliding rail set 20 and the second sliding rail set 30, respectively.

In more detail, the first slider 401 slides on the first proximal slide 201, the second slider 501 slides on the second proximal slide 301, the third slider 601 slides on the first distal slide 202, and the fourth slider 701 slides on the second distal slide 302.

By the rollers 403, 503, 603, 703, it is ensured that the first pedal 40, the second pedal 50, the first handle 60, and the second handle 70 can each slide smoothly and smoothly along the first slide rail set 20 or the second slide rail set 30.

Referring to fig. 3 and 11, with the above configuration, the first pedal 40, the second pedal 50, the first handle 60 and the second handle 70 are all coupled with the transmission unit 80, so as to slide back and forth on the first sliding rail set 20 and the second sliding rail set 30 respectively. The first pedal 40 and the first handle 60 are slidably disposed on the first side 104, the second pedal 50 and the second handle 70 are slidably disposed on the second side 105, such that the first pedal 40 and the second pedal 50 are adjacent to each other in the X direction and are separated by a distance, and the first handle 60 and the second handle 70 are also adjacent to each other in the X direction and are separated by another distance. Because the first sliding rail set 20 and the second sliding rail set 30 are disposed in the upright 101 in a concentrated manner, they are located just in the central position of the trunk of the operator a (the operator a please match fig. 14), so that excessive space is not occupied, and the operator a can operate the climbing machine more naturally.

Referring to fig. 7, 8 and 11, in operation, the left foot and the right foot of the operator a constantly keep stepping on each other (the operator a please match fig. 14), that is, when the left foot of the operator a steps down on the first pedal 40, the first belt 801 rotates along with it, so as to drive the first belt pulley 803 and the second belt pulley 804 to rotate; at this time, since the second pulley 804 and the fourth pulley 806 are synchronously coupled, the fourth pulley 806 drives the second belt 802 and the third pulley 805 to rotate again, so that the second pedal 50 and the first handle 60 are lifted. Similarly, when the operator a steps down on the second pedal 50, the first pedal 40 and the second handle 70 are raised by the actuation of the transmission unit 80. By alternately stepping on the first pedal 40 and the second pedal 50, the reciprocating motion is achieved. In addition, the climbing machine structure can enable the right hand and the left foot of the operator A to synchronously link up and down, and the left hand and the right foot also synchronously link up and down, so that the climbing machine structure is more in line with actual movement habits.

Referring to fig. 6, 11, 12, 13A and 13B, the resistance unit 90 is disposed on the support 10, and the resistance unit 90 includes a driving wheel 901, a driven wheel 902, a small driven wheel 9021, a resistance wheel 903, a resistance piece 904, a third belt 905, a fourth belt 906 and a control piece 907, so as to apply a resistance to the first pedal 40, the second pedal 50, the first handle 60 and the second handle 70, thereby enhancing the training effect. The driving wheel 901 is fixed on the rotating shaft 807, the driven wheel 902 and the small driven wheel 9021 rotate coaxially and synchronously, the small driven wheel 9021 is connected with the driving wheel 901 via the third belt 905, the driven wheel 902 is connected with the resistance wheel 903 via the fourth belt 906, and the resistance piece 904 corresponds to the resistance wheel 903. Preferably, the resistance element 904 is a magneto-resistive element, and the control element 907 is disposed on the bracket 10 and connected to the resistance element 904. The position of the magneto-resistive element is controlled by the control member 907, so as to change the resistance according to the own requirement of the operator a (the operator a please refer to fig. 14). The drag wheel 903 of the present invention may also employ other drag configurations, such as frictional drag, windage, water drag, motors, or electro-magnetic brake, among others.

Referring to fig. 12, 13A, 13B and 14, when the operator a steps on the first pedal 40 and the second pedal 50 in turn, the second pulley 804 and the fourth pulley 806 drive the driving wheel 901 to rotate, and then the driving wheel 901 drives the resistance wheel 903 to rotate via the third belt 905, the small driven wheel 9021, the driven wheel 902 and the fourth belt 906. The resistance force is applied to the resistance wheel 903 by the resistance piece 904, which is transmitted via the resistance unit 90 to the second pulley 804 and the fourth pulley 806, which in turn is applied to the first pedal 40, the second pedal 50, the first handle 60 and the second handle 70.

Referring to fig. 3, 14 and 15, by arranging the first slide rail set 20 and the second slide rail set 30 in parallel, the first top end 20a, the second top end 30a and the column top end 101a are not higher than the eye position of the operator a in the height direction, and the vision of the operator a is not blocked by the first slide rail set 20, the second slide rail set 30 and the column 101. Whether the screen 100 is provided on the climbing machine structure as in the present embodiment, or a separate television, projection screen, etc., the operator a can easily view without turning his head or looking obliquely.

In the second embodiment, the second distal slide rail 302a includes two parallel tubular guide rails 3021a, each of the four corners of the fourth slider 701a is provided with a sliding seat 7011a, each sliding seat 7011a is provided with a channel 7012a corresponding to the tubular guide rail 3021a, a bushing 7013a is fixed in each channel 7012a, the bushing 7013a is made of a low friction and wear resistant material, and the bushing 7013a is respectively sleeved on the tubular guide rail 3021a to enable the fourth slider 701a to slide on the second distal slide rail 302 a.

In practical implementation, the cross-sectional profile of the channel 7012a is approximately three-quarter circumference, as viewed in the cross-sectional direction perpendicular to the axial direction of the sliding seat 7011a, so as to be held by the tubular rail 3021a and be able to slide smoothly.

The remaining structures of the second embodiment can be applied to the corresponding structures of the first embodiment, and will not be repeated here.
