Description

Technology area

The present invention relates to fitness equipment, and more particularly to the structure of a fitness bike.

Since modern people are busy, they do not have enough time to exercise, and fitness equipment installed indoors, such as fitness bikes, can be conveniently used for spare time, and has attracted attention. However, since ordinary fitness equipment has an enormous volume, storage in a room is a troublesome problem.

Considering the convenience of storage, the industry has developed a foldable fitness bike that can be folded after use to reduce the storage space. The conventional fitness bike achieves the exercise training effect by repeating the movement of the user pedaling with both feet, but although only the user's lower limb can be trained, other parts cannot be trained and exercise There was a lack of completeness.

The purpose of the present invention is to provide a foldable fitness bike in which the handrail can swing relative to the bike frame. A further effect of training can be achieved.

It is a perspective view which shows the three-dimensional structure of this invention. It is an exploded view of the three-dimensional structure of the present invention. It is a figure which shows the folding state of this invention. It is a figure which shows the other Example of the drag apparatus of this invention. It is a figure which shows the use condition of this invention. It is a figure which shows the use condition of this invention.

1 and 2 show a foldable fitness bike according to the present invention, which includes a main bike frame 1 and a sub bike frame 2 which are pivotally connected to each other, and the sub bike frame 2 is a bar member installed at two intervals. 21, the main bike frame 1 penetrates between the two bar members 21. A saddle 11 is provided at the top of the main bike frame 1 and a rotating mechanism 12 that can be driven by a rowing operation is provided at the bottom. In addition, the rotation mechanism 12 can increase the training effect when the user is rowing by increasing the difficulty of rotation through a device that provides further drag.

Next, the main bike frame 1 is provided with a first fixed device, and one end of the main bike frame 1 is fixed to the sub bike frame 2 to fix the main bike frame 1 and the sub bike frame 2 after deployment. be able to. In the present embodiment, the first positioning device includes a connecting rod 13 and a positioning socket 22, one end of the connecting rod 13 is pivotally connected to the main bike frame 1, and the positioning socket 22 is connected to the sub bike frame 2. The connecting rod 13 is inserted into the stereotaxic socket 22. A number of localization holes 131 are provided along the connecting rod 13, and a first insertion hole 221 is provided in the localization socket 22, so that the deployment angles of the main bike frame 1 and the sub bike frame 2 are different. Along with this, the insertion position of the connecting rod 13 into the localization socket 22 also changes, the localization hole of the connection rod 13 is made to correspond to the first insertion hole 221, and the first insertion rod 222 is connected to the localization hole and the first insertion hole 221. By passing through one insertion hole 221 simultaneously, the main bike frame 1 and the sub bike frame 2 can be fixed.

Accordingly, when the first insertion rod 222 is pulled out, the main bike frame 1 and the sub bike frame 2 swing relative to each other to form a combined state as shown in FIG. Can be stored easily. In the present embodiment, by having the bent portions 23 bent toward the main bike frame 1 at the top end and the bottom end of the sub bike frame 2, both can be brought closer together and occupy the whole. Reduce space to the maximum.

On the other hand, a pivot portion 24 is provided at the top end of the sub bike frame 2, and the bottom end of the handrail 3 is pivoted on the pivot portion 24 so as to be swingable with respect to the sub bike frame 2. . Further, the sub-bike frame 2 is provided with a limiting member 25 that limits the swing range of the handrail 3. The sub-bike frame 2 is provided with a second localization device, and by fixing one end thereof to the handrail 3, the sub-bike frame 2 and the handrail 3 can be fixed. Limit movement. In the present embodiment, the sub bike frame 2 and the handrail 3 are provided with second insertion holes 26 and 31 at positions corresponding to each other other than both pivot contacts, and both the second insertion holes 26 and 31 are provided. The handrail 3 can be fixed by inserting the second insertion rod 27 when the positions are aligned.

Further, the handrail 3 increases the drag force of the swing via the drag device 4. In this embodiment, the drag device 4 is a hydraulic cylinder, one end of which is connected to the sub-bike frame 2, the other end is connected to the handrail 3, and the handrail 3 swings with respect to the sub-bike frame 2. Thus, the length can be changed, and a drag force against the swinging of the handrail 3 is generated. Further, the sub-bike frame 2 is provided with a first connection seat 28, the handrail 3 is provided with a second connection seat 32, and the first connection seat 28 or the second connection seat 32 is provided with A plurality of connection ports for connecting the drag devices 4 are provided. In this embodiment, the first connection seat 28 is provided with one connection port 281, and the second connection seat 32 is provided with three connection ports. One connection port 321 is provided, one end of the drag device 4 is connected to the connection port 281 of the first connection seat 28, and the other end is one connection selected from the three connection ports 321 of the second connection seat 32. Connected to the mouth. Due to the difference in the selection of the connection port, the original length of the drag device 4 is also different, and the initial drag provided to the handrail 3 is also changed and can be selected according to the demand of the user.

Another embodiment of the device 4 is shown in FIG. The first connection seat 28 and the second connection seat 32 are provided with one connection port 281, 321, respectively, and both ends of the drag device 4 are connected to the connection port 281, 321, respectively. The drag device 4 is an adjustable attenuator. The drag device 4 is provided with an adjustment head 41. By rotating the adjustment head 41, the initial drag provided to the handrail can be adjusted. it can.

With the structure described above, when performing training using the present invention, the user sits on the saddle 11 and repeats the operation of stroking the rotating mechanism 12 with both feet to achieve the training effect of the lower limb region, as shown in FIG. By pulling the handrail 3 backward as shown, and pushing the handrail 3 forward as shown in FIG. 6, the handrail 3 is swung with respect to the sub-bike frame 2, The user's arm and back muscle groups can be trained simultaneously. By responding to the above-mentioned movement of the upper limb part and the above-described movement of both feet, the user is given a general exercise training effect and the practicality of the present invention is enhanced.
