Description

Bicycle support frame structure with buffering inclined force

In this case, a bicycle support frame structure with a buffering tilting force function is provided to provide a child with a biased position during riding, and can be bent by an auxiliary wheel positioned on both sides of the rear wheel center shaft bolt of the vehicle body. The folding angle and the cushioning sheet have a cushioning effect to generate a shock-absorbing effect, and the concave slope of the horizontal section end of the support frame is used to restrict the re-tilt from occurring, so as to achieve the purpose of protection.

According to the general information about the auxiliary wheels installed on both sides of the bicycle rear wheel, the purpose is to protect the riding children from being caused by the riding of the ground or the unfamiliar factors. Supported by the auxiliary wheels on both sides to avoid car crash damage; the auxiliary wheels that are currently seen are assembled on both sides of the rear wheel of the car body, and are assembled by a diagonally shaped L-shaped support frame at both ends. The central axle pin of the wheel and the auxiliary wheel are used as a timely balance to provide the ride body.

However, the auxiliary wheel support frame currently seen is mostly an integral L-shaped angle, so whenever one of the auxiliary wheels touches the ground, It is a hard-pressed state of gravity, so there is a kind of collision with the touch of the ground, as if there is a feeling of being "crashed", so the situation repeats from time to time.

Therefore, the applicant has to study repeatedly to develop the original creation and apply. The purpose of the present invention is to provide a bicycle support frame structure with a buffering tilting force function, which provides a child with a bias when riding, but can be placed on both sides of the central axle pin of the rear wheel of the vehicle body. The auxiliary wheel is bent at an angle and has a cushioning sheet to suppress the shock to achieve a protective purpose.

The purpose of the present invention is to provide a bicycle support frame structure with a buffering tilting force, wherein the support frame is assembled on the side of the rear axle center axle of the vehicle body, and the middle section of the support frame is inclined at an angle and above The extension is bent into a vertical paragraph, and the lower portion is extended and bent into a horizontal section, so that a perforation in the vertical section is placed in the central axle pin of the rear wheel, and then a nut is combined and positioned; The horizontal section can be pivoted with a wheel seat, and two screw holes are provided beside the pivot arm of the horizontal section, and a concave slope is provided above the end edge of each pivot arm.

The purpose of this creation is to provide a cushioning tilting force The bicycle support frame structure, wherein the wheel base is assembled in the mandrel of the auxiliary wheel, and has a recessed space on the surface of the wheel seat for attaching a buffer sheet to the recessed space on the surface of the wheel seat and below the support frame After the horizontal section, the two bolts are passed through the perforations of the buffer sheet and then screwed into the screw holes of the horizontal section.

The purpose of the present invention is to provide a bicycle support structure having a cushioning tilting force, wherein when the vehicle body is deflected, that is, by the pivot between the wheel base of the auxiliary wheel and the horizontal section below the support frame The knot acts and appears to be bent.

The purpose of the present invention is to provide a bicycle support frame structure with a buffering tilting force, wherein when the wheel base of the auxiliary wheel and the horizontal section below the support frame exhibit a bending effect, the buffer piece located above the two is made. Suppression, in order to slow down the force, the cooker has a shock-absorbing effect.

The purpose of the present invention is to provide a bicycle support frame structure with a buffering tilting force, wherein when the car body is tilted and the wheel seat of the auxiliary wheel and the horizontal section below the support frame are bent, the support is supported. The concave bevel at the end of the horizontal section of the frame is used to limit the occurrence of re-tilt.

First of all, please refer to the details as shown in the first and second figures and the following detailed description: In this case, a bicycle support frame structure with a buffering inclined force function is to assemble the two support frames 2 at the center of the rear wheel 11 of the vehicle body 1, respectively. The two sides of the shaft bolt 111, wherein the vehicle body 1 can be installed with different vehicle functions (such as the third and fourth figures), the middle section of the support frame 2 is inclined at an angle, and is extended and bent into a vertical section 21 at the top. And the lower portion is extended and bent into the horizontal section 22, so that the vertical section 21 has a through hole 211 which is nested in the central axle pin 111 of the rear wheel 11, and is then positioned by a nut 1A; The horizontal section 22 can be pivoted with a wheel base 3, and two screw holes 222 are provided beside the pivoting arm 221 of the horizontal section 22, and a concave slope 223 is provided above the end edge of each pivoting arm 221. On the surface of the wheel base 3, there is a recessed space 31 for a buffer sheet 4 to be attached to the recessed space 31 on the surface of the wheel base 3 and the horizontal section 22 below the support frame 2, and then buffered by the two bolts 2A. The perforations 41 of the sheet 4 are then screwed into the screw holes 222 of the horizontal section 22, and the wheel base is positioned. 3 is assembled on the auxiliary wheel 5 In the mandrel 51.

提供 Providing a ride after assembly, when there is a tendency to deflect, it can be bent by the pivotal action between the wheel base 3 of the auxiliary wheel 5 and the horizontal section 22 below the support frame 2, that is, In the first stage of the buffering effect, and then by the buffer sheet 4 located above the two (such as the fifth figure), in order to form the second stage of the damping force to have a shock-absorbing effect.

Since the tilting of the vehicle body has its limit to avoid the occurrence of panic caused by the excessive tilt angle, the concave bevel 223 of the end of the horizontal section 22 of the support frame 2 is used to limit the wheel base 3 and the auxiliary wheel 5. Tilt angle (as shown in Figure 6).

To sum up, it is true that this creation does meet the requirements for the establishment of Article 104 of the Patent Law. Please ask for the establishment of the patent right, and the granting of the legal patent right.
