KICKSTAND FOR BIKES BACKGROUND OF THE INVENTION

Field of the invention

[0001] The present invention relates to a kickstand of a bicycle, and more particularly, to a

kickstand that is secured to the chainstay firmly.

Descriptions of Related Art

[0002] The conventional kickstand of a bicycle has a head connected to the bicycle frame

such as the chainstay and includes a leg which is pivotably connected to the head. When

parking the bicycle, the leg is kicked downward and contacts the ground, and the leg extends at

angle relative to the bicycle to support the bicycle. The conventional kickstands are disclosed to

Taiwanese Utility Models M290841 and M468466, and CN210555274U of China.

[0003] However, the shape of the cross section of the chainstay is round, so that the head of

the kickstand must be curved to as to be mounted to the tube of the chainstay, and two bolts

are used to secure the tube of the chainstay to the head of the kickstand.

[0004] Usually, the tube of the chainstay is smooth, and the kickstand is difficult to be

properly secured to the tube. In other words, the head of the kickstand eventually will slip or

loose relative to the tube of the chainstay by vibration or impact. Therefore, the users must

check the tightness of the bolts to ensure that the kickstand functions as expected. On the contrary, if the bolts are overly tightened, the head of the kickstand may be deformed, and the deformed head cannot hold the tube of the chainstay, or even broken.

[0005] The present invention intends to provide a kickstand of a bicycle to eliminate

shortcomings mentioned above or to provide the user with an alternative.

SUMMARY OF THE INVENTION

[0006] The present invention relates to a kickstand and comprises a head and a leg is

pivotably connected to the lower end of the head. A clamp is connected to the head by multiple

locking members. A first pad is located at the inside of the clamp and faces the head. Multiple

screws are threadedly connected to the clamp and each include a contact end. The contact ends

of the multiple screws extend beyond the clamp and contact against the first pad to partially

deform the first pad. The tube of the chainstay is clamp between the head and the clamp.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[00022] Referring to Figures 1 to 5, the kickstand 100 of the present invention comprises a

head 200 and a leg 300 which is pivotably connected to the lower end of the head 200. A clamp

400 is connected to the head 200 by multiple locking members 110. A first pad 500 is located at

the inside 410 of the clamp 400 and facing the head 200. Multiple screws 600 are threadedly

connected to the clamp 400 and each include a contact end 610 and a driving end 620. The

contact ends 610 of the multiple screws 600 extend beyond the clamp 400 and contact against

the first pad 500 to partially deform the first pad 500 when the head 200 is mounted to the

chainstay 710 of a bicycle 700. In this embodiment, there are three locking members 110, two

of the three locking members 110 extend through the clap 400 and go above the chainstay 710

as shown in Figure 3 and are connected to the head 200. The third one of the three locking

members 110 extends through the clap 400 and go below the chainstay 710 and is connected to

the head 200. In this embodiment, there are four screws 600.

[00023] When installing the kickstand 100 to the bicycle 700, the head 200 is located between

the wheel and the chainstay 710, and the clamp 400 is located at outside of the chainstay 710.

The bolts 110 extend through the clamp 400 and are threadedly connected to the head 200.

The first pad 500 partially contacts the chainstay 710, and then rotating the screws 600 by using

a tool (not shown) toward the clamp 400 until the contact ends 610 of the multiple screws 600

extend beyond the clamp 400 and contact against the first pad 500 to partially deform the first

pad 500 which contacts against the chainstay 710 of the bicycle 700. There are four contact

points of the first pad 500 against the chainstay 710 of the bicycle 700 so that the kickstand 100

does not rotate or slip relative to the chainstay 710.

[00024] Specifically, the inside 410 of the clamp 400 includes a first face 411, a second face

412 and a curve face 413 which is formed between the first and second faces 411, 412. By the

inside 410 of the clamp 400, the chainstay 710 of different cross sections, such as round tube, oval tube, teardrop shaped tube or polygonal tube can be clamped by the clamp 400 and the head 200 as shown in Figures 6 and 7.

[00025] The clamp 400 includes an outside 420 which includes a first protrusion 421, a second

protrusion 422 and a recessed area 423 formed between the first and second protrusions 421,

422. Multiple first threaded holes 424 are defined through the first protrusion 421 and the first

face 411of the clamp 400. Multiple second threaded holes 425 are defined through the second

protrusion 422 and the second face 412 of the clamp 400. The screws 600 are threadedly

connected to the first and second threaded holes 424, 425. The axes of the first and second

threaded holes 424, 425 extend toward different directions so that the screws 600 contact the

first pad 500 and apply forces to the chainstay 710 in different directions to ensure that the

chainstay 710 is secured in a balance way. The recessed area 423 reduces weight of the clamp

400. The first and second protrusions 421, 422 are more visible when assembling the clamp 400

to the head 200.

[00026] As shown in Figure 6, each of the first threaded holes 424 includes a first axis L1, and

each of the second threaded holes 425 includes a second axis L2. An angle of 50 degrees to 70

degrees is formed between the first and second axes L1, L2. Preferably, the angle is 60 degrees.

Therefore, the screws 600 apply forces to the first pad 500 and the chainstay 710 in multiple

directions.

[00027] As shown in Figure 4, when the contact ends 610 of the screws 600 do not protrude

beyond the first and second threaded holes 424, 425, the driving end 620 of each of the screws

600 is protruded beyond the outside 420 of the clamp 400 to form the screws 600 as a warning status. When the contact ends 610 of the screws 600 protrude beyond the first and second threaded holes 424, 425, the driving end 620 of each of the screws 600 is not protruded beyond the outside 420 of the clamp 400 to form the screws 600 as a contacting status. The first pad

500 is partially deformed in the contacting status. As shown in Figure 5, by the warning status

and the contacting status of the screws 600, the users can easily tell whether the kickstand 100

is secured to the chainstay 710 or not.

[00028] It is noted that the first pad 500 includes a first contact portion 510 and two first

lateral portions 520 which are formed to two sides of the first contact portion 510. The first

contact portion 510 includes a first outer face 530 and a first inner face 540 which is located

opposite to the first outer face 530. The first outer face 530 contacts the inside 410 of the clamp

400. The two first lateral portions 520 respectively contact two lateral sides 430 of the clamp

400. Therefore, the first pad 500 does not shake when it is installed to the inside 410 of the

clamp 400.

[00029] As shown in Figure 8, the first outer face 530 of the first pad 500 includes separated

first ridges 550 protruded toward the two first lateral portions 520. The first ridges 550 provide

friction between the first pad 500 and the chainstay 710.

[00030] The head 200of the kickstand 100 includes an extension 210 and a connection end

220. The connection end 220 is connected to the leg 300. The clamp 400 is connected to the

extension 210 of the head 200 by multiple bolts. A second pad 230 contacts the extension 210

of the head 200. The second pad 230 includes a second contact portion 231and two second

lateral portions 232 which are formed to two sides of the second contact portion 231. The second contact portion 231includes a second outer face 233 and a second inner face 234 which is located opposite to the second outer face 233. The second outer face 233 contacts the extension 210 of the head 200. The two second lateral portions 232 respectively contact two sides of the extension 210. The second outer face 233 of the second pad 230 includes separated second ridges 235 protruded toward the two second lateral portions 232. By the first and second pads 500, 230, the kickstand 100 receives forces from two directions to be connected to the chainstay 710.

[00031] While we have shown and described the embodiment in accordance with the present

invention, it should be clear to those skilled in the art that further embodiments may be made
