Description

Brake pad mechanism using dry skates

[1] The present invention relates to a brake shoe mechanism for achieving one-way braking of roller skates by means of a brake swing block or a shoe wheel bracket deflection.

Background technique

[2] At present, the roller skates on the market are mostly brake blocks fixed on the wheel brackets, mainly relying on the friction between the brake blocks and the ground to achieve the purpose of braking. The applicant of the present invention applied in ₂₀₀₅ to "a roller skate with a shoe wheel bracket swinging brake" (application number is 200510022023.3), which divides the shoe wheel bracket into front and rear shoe wheel brackets, and in two shoe wheel brackets The brake mechanism is provided with a brake mechanism that is braked by the deflection of the shoe wheel bracket. The brake mechanism is connected by a brake link movably connected to the shoe wheel bracket, a brake block connected to the brake link, and a link top member and a brake link. The spring mechanism and the like have the brake effect, but the structure is complicated, and the brake block only contacts the side of the shoe wheel, the braking force is insufficient, and the unidirectional braking function is not provided, thereby affecting the safety of the whole roller skate. .

Summary of the invention

[3] It is an object of the present invention to provide a brake shoe mechanism for roller skates which can be deflected by the brake sway block or the front and rear shoe wheels are individually touched to cause the shoe wheel bracket to deflect to achieve a one-way braking effect.

[4] The inventive concept of the present invention is to mount the brake pad on the extended brake bracket of the brake swing block or the sole shell, and directly use the deflection of the brake swing block or the shoe wheel bracket to promote the contact of the brake pad with the shoe wheel. The brake pad can be displaced after the wheel is rotated with the shoe wheel, thereby directly forming a one-way pressing force on the soft surface of the shoe wheel and braking the shoe wheel to brake.

[5] Specifically, the technical solution to achieve the above object of the present invention is that the brake pad mechanism of the present invention (see FIG. 1) has a brake pad connectable to a brake swing block that is deflected by ground contact, and is characterized by a brake swing block. There is a brake pad swing restricting member, and the brake pad can be in contact with the shoe wheel with the brake swing block deflecting; the brake pad of the brake pad is a surface that is substantially smooth and can be matched with the outer upper half of the wheel surface of the shoe wheel. On the tread, the brake pads can be offset and brake the shoe wheel as the wheel rotates behind the wheel. When the brake swaying block connected to the extension bracket of the shoe wheel bracket touches the ground and is deflected, the brake pad and the shoe connected to the brake swaying block are driven. The outer upper half of the wheel is in contact with the surface of the wheel, and if the rear wheel continues to rotate forward (after the brake swing block is placed behind the roller skate), the lower end of the brake pad will then rotate inwardly, which is offset inward. The movement will promote the brake surface of the brake pad to gradually squeeze the rear shoe wheel, thereby immersing the soft surface of the wheel and unidirectional braking (the brake pad can be trapped on the surface of the shoe wheel to a greater extent than the deformation elasticity of the shoe wheel, thereby completely ending If the shoe wheel rotates backwards, if the shoe wheel reverses backwards, the brake pad has frictional resistance to the rear wheel, but there is no braking effect. When the brake swing block returns to the ground, the brake pads return to their own position.

[6] The brake pad is movably connected to the groove on the brake swing block through the connecting shaft, and the left and right outer sides of the groove directly constitute the swing restricting member of the brake pad. When the brake swing block is off the ground, the brake pads can be returned to the position due to their own weight.

[7] The brake pad is movably coupled to the groove on the brake swing block via the connecting shaft; the swing restricting member of the brake pad is composed of an elastic body disposed in the recess. The elastic body is a single piece of cymbal, embedded on the left side of the brake pad; the elastic body is a double piece of cymbal, which is embedded on the left and right sides of the brake pad.

[8] The brake pad may also be connected to a groove in the brake swing block by a connecting member, and the swing restricting member of the brake pad is composed of an elastic body disposed between the bottom of the brake pad and the brake swinging block.

[9] The above brake pad may also be coupled to the brake swing block via an elastic piece, and the swing restricting member of the brake pad is constituted by a bump provided on the brake swing block to restrict the swing of the elastic piece.

[10] The above-mentioned elastic body or elastic piece not only has the effect of limiting the swinging amplitude of the brake pad, but also acts to prompt the brake pad to quickly return after the brake swinging block is off the ground.

[11] Another technical solution of the present invention for achieving the above object is that the brake pad mechanism of the present invention (see FIG. 7_8) has a brake pad attachable to an extended brake bracket of a sole shell or a column of a sole, characterized in that The brake pad has a certain elasticity, and the brake pad can be in contact with the shoe wheel when the shoe wheel bracket is deflected; the brake surface of the brake pad is a contact surface which is substantially smooth and can match the outer upper half of the wheel surface of the shoe wheel. The brake pad can be offset and brake the shoe wheel after the wheel is rotated. When the shoe wheel bracket deflects the front end of the shoe wheel bracket by the front shoe wheel, the brake surface of the brake pad contacts the front upper wheel surface of the front shoe wheel, and if the front shoe wheel continues to rotate forward (ie, the front wheel rotates counterclockwise), the brake pad has frictional resistance to the rear wheel, but there is no braking effect; and if the front shoe wheel rotates backward (ie, the front wheel rotates smoothly), the lower end of the brake pad will Lateral (ie, inward) shifting with the rotation of the front shoe wheel (because the brake pad is long, there is some elasticity, so offset can occur), as the brake pad is shifted backward, the brake pad of the brake pad Gradually strong Squeeze the front wheel, thereby squeezing the surface of the soft wheel and braking in one direction; similarly, the brake pad above the rear shoe wheel will also exert a reverse strength on the surface of the soft rear wheel due to the rearward displacement of the wheel. brake.

[12] The brake pads are fixedly attached to the extended brake bracket. Due to the long brake pads, there is a certain deflection flexibility

[13] The brake pad is connected to the extended brake bracket through a connecting shaft, a tension spring is arranged between the brake pad and the extended brake bracket, and a brake pad block is arranged on the extended brake bracket. When the brake pad is turned upside down, the tension spring can be positioned; the block prevents the brake pad from excessively moving. An elastic body may also be disposed between the block and the brake pad on the extended brake bracket, and the elastic body can increase the return force of the brake pad after the brake is released, and realize the return position.

[14] The brake pad is movably connected to the groove in the extended brake bracket through the connecting shaft, and the groove is embedded with an elastic body capable of limiting the amplitude of the brake pad. The elastic body also has the effect of limiting the amplitude of the brake pad swing, and the same can increase the return force of the brake pad after the brake action is released.

[15] The invention has the following advantages: (1) The brake pad directly performs one-way braking on the soft surface of the shoe wheel, and the effect helps to improve the safety of the sliding, and the roller skate has a good prevention of front and rear fall. The role is especially suitable for beginners to learn about roller skating. (The brake pad is deflected by the brake swing block or the shoe wheel bracket to contact the surface of the shoe wheel, and then the shoe wheel is rotated to drive its own offset, causing the brake pad to directly press the soft surface of the shoe wheel and press it in The surface of the shoe wheel is formed in the concave surface to brake the shoe wheel, so the braking force is large, and the braking action is reliable. (3) When the brake swinging block is off the ground or the shoe wheel bracket is gradually level, the braking power is released, and the brake pad is Under the action of gravity or elastic force, it can realize automatic returning, and returning and squatting. (4) The brake mechanism is simple and easy to install. The invention has applied for a utility model patent on the same day.

The structure of the brake pad of this embodiment is shown in FIG. 1 , and has a brake pad 2 connected to the ground-deflectable rear brake swing block 1 , specifically, the groove of the brake pad 2 movably connected to the brake swing block through the connecting shaft 3 . 4, in the groove on the left and right sides of the brake pad is embedded with an elastic body 5 that can limit the swing of the brake pad; the elastic body 5 can also be one, located on the left side of the brake pad (see Figure 2); The body 5 constitutes a swing restricting member of the brake pad, and the elastic body can also adopt a spring structure; the brake surface of the brake pad is a contact surface which is substantially smooth in surface and can match the outer upper half of the wheel surface of the shoe wheel 6 ( As shown in FIG. 3), the brake pad 2 is in contact with the shoe wheel 6 as the brake swinging block 1 is deflected to the ground; the brake pad is displaced after the contact wheel is strongly rotated by the ground contact of the shoe wheel 6, and the shoe is collapsed. The soft surface of the wheel and the surface of the wheeled wheel are about greater than the deformation elastic range of the shoe wheel, so that the shoe wheel can be completely stopped to realize the braking. Since the brake surface of the brake pad is a curved surface that fits the surface of the wheel, the surface of the shoe wheel is not damaged. The roller skate shown in Fig. 1 is composed of a shoe body 7, a sole case 8, a shoe wheel bracket 9 and a front shoe wheel 10, a middle shoe wheel 11 and a rear shoe wheel 6 mounted on the shoe wheel bracket, and the brake swinging block 1 The brake pads 2 and the brake bracket 12 form a complete brake device. The brake bracket 12 is fixed on the shoe wheel bracket 9 or the shoe wheel bracket 9 and the shoe shell 8 by screws; the brake swinging block 1 is connected to the brake bracket 12 through the connecting shaft 13, and the connecting shaft 13 is disposed at a relatively high position. Increase the proportion of the length of the lower part of the brake swing block, increase the pressure of the brake pad; open the limit hole 14 in the brake swing block 1, and set the limit post or limit rod 15 on the brake bracket 12 to extend into the limit hole In this way, the swing range of the brake swing block can be limited; since the lower part of the brake swing block is long and heavy, the brake swing block can be returned to the ground after being lifted by the weight, but it can also be between the brake swing block and the brake bracket. A return spring 16 is provided to enhance the return force.

[26] It is worth mentioning that, in the present embodiment, (1) the brake pad 2 is movably connected to the groove on the brake swinging block 1 through the connecting shaft 3, such as a relatively narrow groove and a 7 or brake pad design. If it is larger and heavier, it is not necessary to insert the elastic body. The left and right outer sides of the groove directly constitute the swing restricting member of the brake pad (see Fig. 4); (2) the brake pad is movably connected through the connecting member 17 After the groove on the brake swing block, the elastic body 5 constituting the brake pad swing restricting member may be disposed between the bottom of the brake pad and the brake swing block (see FIG. 5); (3) the brake pad 2 may also pass through the elastic piece 18 is connected to the brake swing block 1 (the elastic piece is fixed on the brake swing block, The brake pad and the elastic piece are fixed together. The swing restricting member of the brake pad is composed of a projection 19 which is disposed on the brake swing block and can restrict the swing of the elastic piece (see Fig. 6).

(ie, front) the upper wheel surface or the outer (ie, rear) upper half of the wheel surface of the rear shoe wheel 6 that fits the wheel surface (see Figure 3). The front wheel 10 individually forces the front shoe wheel bracket After the deflection, the brake pad 2 is in contact with the surface of the front wheel, and the front wheel 10 is rotated backwards (spinning the needle), the brake pad is driven to be displaced backward, and the braking surface directly collapses the softness of the shoe wheel. The surface and the surface of the shoe wheel are more than the deformation elastic range of the shoe wheel, so that the front wheel is pressed against the top wheel and braked, but the front wheel touches the ground and rotates forward (the reverse pin rotates), and the brake pad has no brake. Effect; the brake pad 2 on the rear wheel 6 has the opposite effect. That is, the rear shoe wheel 6 separately forcefully deflects the rear shoe wheel bracket, forcing the rear shoe wheel to contact with the brake pad, and the offset behind the brake pad contact wheel directly occupies the soft surface of the rear shoe wheel, so that the rear shoe wheel 6 You can't continue to turn and brake, but going backwards (backward) doesn't have much impact.

[28] The roller skate shown in FIG. 7 is composed of a shoe body 7, a sole case 8, mutually separated front and rear shoe wheel brackets 9a, 9b, and a front shoe wheel 10, a middle shoe wheel 11 and a shoe wheel bracket.
