Description

Standing bicycle with movable folding seat

The technology to which the present invention pertains provides a bicycle, especially a standing bicycle with a movable folding seat, which can reduce the pressure of the knee joint and the ischial node when the pedal member is stepped on.

A bicycle is a device that can drive the entire structure of a car by stepping on a pair of pedals. In China, Taiwan, and Southeast Asia, the device also has a bicycle, an iron horse, or a Kong Ming car. Cycling is a very good fitness activity for modern people. It not only consumes natural energy and damages the environment, but also strengthens the individual's heart function and prevents high blood pressure. When riding a bicycle, it mainly uses the muscles of the lower body of the human body, especially The muscles on the front side of the thigh and the muscles on the back of the calf can be exercised by riding a bicycle. However, in the design of the bicycle, the posture of the rider is designed to be sitting. This type of riding will make the ischial tuberosity. The point (the protruding point of the thigh bone and the pelvic joint) bears the weight of the upper body of the human body, and when the pedal is stepped on, the butt not only moves left and right, but the two thighs must also be stepped up and down in turn; wherein the ischial node is again It is the fulcrum of the rotation of the thigh, so when the person rides for too long, the spine near the ischium may be caused by excessive friction. The intervertebral disc protrudes, causing pain in the lower back; and stepping on the pedals uses the strength of the thigh to push the body. If the height of the seat is set low, the knees of the legs will be very large when applied. Load, and even sports injuries; therefore, in order to avoid the sports injuries caused by the traditional riding posture, the rider usually raises the buttocks away from the seat to avoid the above situation, but this posture will make the cervical vertebra The disc protrudes and causes a sore neck.

Therefore, the above problems will be the difficulties that the technicians in this field want to solve.

The inventor of the present invention has in view of the above-mentioned deficiencies of the prior art, and proposes a standing bicycle having a movable folding seat, which mainly has the following objects: The first object of the present invention is to enable a person to ride When the time is taken, the pressure on the knee joint and the ischial node is reduced; the standing bicycle with the movable folding seat of the present invention provides the rider to ride the bicycle in a standing position, and the body structure is the front support frame. Forming a V-shape with the rear support frame, the gear frame is provided with a gear portion pedal member, and the driver can directly stand on the bicycle to reduce the bending angle between the thigh and the lower leg to reduce the load on the knee. And a spring member is respectively disposed at the intersection of the front support frame and the rear support frame and the upper support bar frame to achieve the double suspension effect.

A second object of the present invention is that the rider can adopt any posture in a standing position or a sitting position when riding the bicycle. The present invention has a folding seat, and the folding seat is folded in the upper support frame when the person is folded. Riding the bicycle structure in a standing position; when a person wants to ride on the folding seat, the movable folding frame of the upper support frame can be directly pulled to lay the folding seat, by opening or closing the folding seat In order to achieve the function of sitting and standing.

In order to achieve the above objects and effects, only a preferred embodiment will be described herein, and those skilled in the art will be able to carry out the various embodiments.

First, please refer to the first and second figures, which are perspective views of a preferred embodiment of the present invention, and clearly show a standing bicycle 1 with a movable folding seat, mainly including a front support frame 2 , gear portion pedal member 21, upper support rod frame 3, accommodating space 31, movable folding frame 32, folding seat 33, faucet portion 4, front wheel axle body 5, rear wheel axle body 6, spring member 7 and rear support The frame 8 is characterized in that the front support frame 2 and the rear support frame 8 form a V-shape, and the design thereof can produce high added value on the production structure; the rear support frame 8 is provided with a gear portion pedal member 21, The driver can directly stand on the gear portion pedal 21 to drive the standing bicycle 1 with the movable folding seat; the front support frame 2 and the upper support bar frame 3 intersect the faucet portion 4, and the rear support frame 8 is in a U-shaped, the apex of which is connected with the rear axle body 6, the other end of which is connected with the upper support bar frame 3, and the front support frame 2 and the rear support frame 8 and the upper support bar frame 3 are respectively arranged at intersections a spring member 7 to achieve a double suspension effect; the upper support rod frame 3 has a space The accommodating space 31 can store a movable folding frame 32 and a folding seat 33, and can be further opened or closed by pulling the movable folding frame 32 to lay the folding seat 33 connected thereto. The seat 33 is used to achieve the functions of sitting and standing.

The standing bicycle 1 with the movable folding seat of the present invention has the functions of sitting and standing, and can reduce the pressure on the knee joint and the ischial node when the person rides. The method for implementing the invention is as follows Show: When riding the standing bicycle 1 with the movable folding seat of the present invention in a standing position, the feet can be directly stepped on the pedal portion 21 of the gear portion, and the weight of the body can be directly converted into the propulsion power. Then, the faucet portion 4 is held by both hands to control the traveling direction of the standing bicycle 1 with the movable folding seat; when riding the standing bicycle 1 with the movable folding seat of the present invention, the faucet portion 4 and the front portion The spring member 7 between the axle body 5 and the spring member 7 at the central portion of the upper support bar frame 3 respectively produce a shock absorber effect on the front and rear wheels, which can overcome the shortcomings of the road bump and prevent the rider from being affected by the body. The upper support rod frame 3 is not only connected to the spring member 7, but also has a concave accommodating space 31 for placing a movable folding frame 32 and a folding seat 33. , the folding seat The cushion portion of 33 can be any shape and material, and the storable structure design is an important feature of the present invention; if the invention is to be seated in a sitting position, the activity in the accommodating space 31 can be directly pulled. The folding frame 32 is used to lay the folding seat 33 so that a person can ride on it, but the design of the standing bicycle 1 with the movable folding seat according to the present invention can still reduce the bending angle between the thigh and the lower leg. Therefore, the pressure on the knee joint and the ischial node can be reduced.

In the above, the above is a preferred embodiment of the present invention, and the scope of the patent is not limited thereby, and the scope of the patent should be determined by the scope of the patent application attached below.
