Description

rowing machine construction

This invention relates to a rowing machine device that can control two rowing paddles to independently operate reciprocating motions to transmit rotational resistance.

At present, the common paddle-type rowing machine structure, such as the utility model No. CN212439861 "a kind of double paddle rowing machine" patent published in mainland China on February 2, 2021, discloses: including the bracket, and also including the resistance system , two pedals, two paddles and seat cushions, the resistance system is arranged at the front end of the bracket, the resistance system is provided with two resistance ropes, and the two pedals are arranged on both sides of the bracket and are rotatably connected with the bracket , the bottoms of the two paddles are arranged on both sides of the bracket and rotatably connected with the bracket, the upper ends of the two paddles are respectively connected with two resistance ropes, and the cushion slides on the bracket. The resistance rope is tied to the upper end of the rowing paddle to achieve the function of rowing with sculls. Moreover, the rower can tie the ends of the two resistance ropes together to realize the existing rowing method, or it can be used between two resistance ropes. The ends of the ropes are respectively connected with rings, which can realize exercises such as chest expansion. Therefore, the rowing machine not only brings a good experience effect to the user, but also has diversified functions.

However, the bottoms of the two paddles in the prior case of this patent are arranged on both sides of the bracket and are rotatably connected with the bracket, while the upper ends of the two paddles are respectively connected with two resistance ropes. When the paddle is pulled, the resistance rope is stretched, which drives the rope recovery disc to rotate, thereby driving the resistance device to move through the one-way bearing. When the paddle is released, the resistance rope is recovered through the rope recovery disc, so the two paddles are pulled back and forth to realize double oars rowing. Since the two resistance ropes are located above the paddle, they will cause hindrance and inconvenience when pulled, and affect the operator's actions.

Therefore, there is the invention No. I644705 "rowing exercise device" patent case announced on December 21, 107, which discloses that it includes a base unit, two rowing units and a resistance unit. The base unit includes two bearing seats extending outwards laterally. Each rowing unit includes a guide rod and a paddle rod. The guide rods are arranged on respective bearing seats so as to be movable along their own axial directions, and extend outward and downward. The paddle has a first joint and a second joint. The first contact is rotatably arranged on the bearing base. The second joint is pivotally connected with the guide rod. The rotation of the paddle rod around the first contact point drives the guide rod to move along its own axis. The resistance unit provides resistance to the paddles. Due to the limitation of the movable orientation of the guide rods, the user will move inwardly and upwardly when pulling the paddle rods, thereby simulating the actual paddling action.

The paddle unit of this patent is linked by multiple connecting rods, so the structure is relatively complicated, and in order to make the paddle rods on the left and right sides reciprocate independently, two sets of independent paddles must be provided respectively. The paddle unit and the resistance unit are used to achieve the effect of the independent reciprocating motion of the paddle shaft. However, such a twice-increased component structure results in a larger overall volume, relatively increased manufacturing and maintenance costs and failures, and thus is not ideal for use.

When using the paddle force application mode, as shown in the third, fourth and ninth figures, the operator F can sit on the seat cushion 12 and hold the two paddles 21 with both hands. The holding end 24 of this. Then pull the two paddles 21 toward the rear end of the base frame 1 with both hands backward and outward, so that the two paddles 21 pivot according to the first axis X and the second axis Y respectively, to simulate rowing Actions. When the paddle 21 is pulled backward (as shown in the fifth figure and the fifth figure A), the first linkage 411 of the paddle linkage 41 can be pulled through the rocker arm end 251, and the first linkage 411 Then link the first small wheel of the first driven wheel 42 The wheel 421 and the first large wheel 422 rotate toward the first rotation direction R1, and the first large wheel 422 drives the paddle one-way driving wheel 43 through the second linkage 412 to drive the first shaft 3 to rotate toward the first rotation direction.

When the paddling one-way driving wheel 43 is idling on the first rotating shaft 3 in the second rotation direction R2, the first rotating shaft 3 remains stationary, so the resistance unit 5 will not affect the rowing one-way driving wheel 43 in the second rotating direction. The rotation of R2 creates any resistance. If the paddle 21 on the left side is used alone to pull backward, the paddle unidirectional drive wheel 43 on the left side will drive the first rotating shaft 3 toward the first rotation direction R1, thereby obtaining the resistance of the resistance unit 5. At this time, if the paddle on the right side 21 does not move, the rotation of the first rotating shaft 3 toward the first rotating direction R1 does not cause the right paddle one-way driving wheel 43 to rotate together, but the right paddling one-way driving wheel 43 idles on the first rotating shaft 3; Similarly, if only the right paddle 21 is used to pull backward, the left paddle unidirectional drive wheel 43 will also idle on the first rotating shaft 3 .

Therefore, the above two paddles 21 can be operated independently, that is, the single paddle operation or the double paddle operation can be freely selected in practice.

In this creative embodiment, the interlocking of the rowing unit 2 and the rowing interlocking unit 4 is used to obtain the rotation resistance, and the operator F can pull the two rowing paddles 21 back and forth to perform a training mode of rowing force, especially, The paddles 21 on the left side and the paddles 21 on the right side can be operated independently or simultaneously. The operation is diversified, and the volume of the entire rowing machine can be reduced, the effect of not occupying space and the diversification of operation modes can be achieved.
