Description

Technical Field

[0001] This application pertains to the field of furniture manufacturing, specifically a brake wheel that allows for easy identification of braking status. Background Technology

[0002] Most chairs on the market use brake wheels that require manual operation and are not easy to operate, or even more complicated brake wheels. At the same time, most brake wheels on the market are not easy to distinguish whether the wheel is in the brake state or the unlocked state. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a brake wheel that easily identifies the braking state by setting an identification mark on the wheel seat to cooperate with the brake pedal. This allows the identification mark to be seen when braking and to be covered by the pedal when not braking, thus solving the problem of how to indicate whether the wheel is in a braking or unlocked state.

[0004] To achieve the above objectives, the technical solution adopted in this application is:

[0005] A brake wheel with easily identifiable braking status includes a wheel seat, a wheel, and a brake plate. The wheel is rotatably mounted on the wheel seat. The wheel has a brake response structure that cooperates with the brake plate. The brake plate has a brake structure that cooperates with the brake response structure. The brake plate is rotatably mounted on the wheel seat. The wheel seat has a first position and a second position that cooperate with the brake plate. The wheel seat also has an identification mark. The brake plate has a pedal. When the brake plate is in the first position, the brake structure triggers the brake response structure, causing the wheel to brake, and the pedal does not cover the identification mark. When the brake plate is in the second position, the brake structure does not trigger the brake response structure, and the pedal covers the identification mark.

[0006] Preferably, the braking response structure includes an annular wall and grooves. The annular wall is coaxially provided on the end face of the wheel, and a plurality of grooves are provided equidistantly around the central axis of the wheel on the inner circumferential wall of the annular wall.

[0007] Preferably, the brake plate is rotatably mounted on the wheel seat at both ends. One end of the brake plate is provided with a brake structure that extends into the space enclosed by the end face of the wheel and the annular wall and cooperates with the groove. The other end of the brake plate is a free end. The rotation axis of the brake plate is parallel to the rotation axis of the wheel, and there is a preset distance between the rotation axis of the brake plate and the rotation axis of the wheel.

[0008] Preferably, the brake structure is a locking post that mates with the groove, and the locking post is radially disposed at one end of the brake plate within the space enclosed by the end face of the wheel extending into the wheel and the annular wall.

[0009] Preferably, the brake plate has an elastic plate on the end face near the rotation axis of the wheel, and the side of the elastic plate facing the rotation axis of the wheel has two arc-shaped grooves. The connecting line segment between the two arc-shaped grooves is parallel to the end face of the wheel. The wheel seat has an arc-shaped protrusion that cooperates with the arc-shaped grooves. When the arc-shaped protrusion is engaged in one of the arc-shaped grooves, the engaging post is engaged in the groove. When the arc-shaped protrusion is engaged in the other arc-shaped groove, the engaging post is disengaged from the groove.

[0010] Preferably, the distances from the two arc-shaped slots to the rotation axis of the brake plate are equal.

[0011] Preferably, the elastic plate and the brake plate are integrally formed, and a hollow structure is provided between the two ends of the brake plate and the elastic plate.

[0012] Preferably, the wheel seat has an arc-shaped plate on the side facing away from the wheel. The center of the virtual circle B containing the arc of the arc plate is located on the rotation axis of the brake plate. The identification mark is provided on the raised surface of the arc plate. The plane containing the virtual circle B is parallel to the end face of the wheel. The pedal is provided at the free end of the brake plate. The length of the connection between the brake plate and the pedal is greater than the center of the virtual circle B. The projection of the identification mark on the axis of the wheel is a straight line L. The projection of the pedal on the axis of the wheel is a straight line M. The straight line L is located between the two ends of the straight line M. The curvature of the pedal is greater than the curvature of the identification mark.

[0013] Preferably, the identification mark is a colored area coated on the raised surface of the curved plate.

[0014] Preferably, the identification mark is a phosphor area coated on the raised surface of the arc-shaped plate.

[0015] Preferably, a support member is provided on the lower surface of the end of the pedal facing away from the wheel. When the brake plate rotates to engage with the locking post in the lower groove of the two grooves, the end of the support member facing away from the pedal is flush with the lowest end of the wheel.

[0016] Compared with the prior art, this application has the following beneficial effects:

[0017] This application adopts an identification mark on the wheel seat that cooperates with the brake wheel when the pedal is pressed, and designs a brake wheel that is easy to identify the braking state. This makes the identification mark visible when braking and covered by the pedal when not braking, thus solving the problem of how to show whether the wheel is in a braking state or an unlocked state.

[0024] like Figure 1-5 As shown, a brake wheel with easily identifiable braking status includes a wheel seat 1, a wheel 2, and a brake plate 3. The wheel 2 is rotatably mounted on the wheel seat 1. The wheel 2 has a brake response structure that cooperates with the brake plate 3. The brake plate 3 has a brake structure that cooperates with the brake response structure. The brake plate 3 is rotatably mounted on the wheel seat 1. The wheel seat 1 has a first position and a second position that cooperate with the brake plate. The wheel seat 1 also has an identification mark 4. The brake plate 3 has a pedal 13. When the brake plate 3 is in the first position, the brake structure triggers the brake response structure, causing the wheel 2 to brake, and the pedal 13 does not cover the identification mark. When the brake plate 3 is in the second position, the brake structure does not trigger the brake response structure, and the pedal 13 covers the identification mark 4.

[0025] In this embodiment, when the pedal 13 on the brake plate 3 is pressed down, the brake plate 3 activates the brake response structure to lock the wheel 2, i.e., brake. At this time, the pedal 13 does not cover the identification mark, so the user can know that the brake is engaged. When the user hooks the pedal 13 with their foot, the brake plate 3 leaves the brake response structure, thereby releasing the wheel 2 from the brake. Then, the pedal 13 covers the identification mark 4. In this way, the user can determine whether the brake is engaged by whether the pedal 13 covers the identification mark 4, thus solving the problem of how to display whether the wheel is engaged or disengaged.

[0026] As a preferred embodiment, the braking response structure includes an annular wall 5 and grooves 6. The annular wall 5 is coaxially provided on the end face of the wheel 2, and a plurality of grooves 6 are provided at equal intervals around the central axis of the wheel 2 on the inner circumferential wall of the annular wall 5.

[0027] By using the groove 6, the brake structure can be controlled to engage with the groove 6. If it engages with the groove 6, the wheel 2 is braked; if the brake structure is outside the groove 6, the brake on the wheel 2 is released.

[0028] In a preferred embodiment, the brake plate 3 is rotatably mounted on the wheel seat 1 at both ends. One end of the brake plate 3 has a braking structure that extends into the space enclosed by the end face of the wheel 2 and the annular wall 5 and engages with the groove 6. The other end of the brake plate 3 is a free end. The rotation axis of the brake plate 3 is parallel to the rotation axis of the wheel 2, and there is a preset distance between the rotation axis of the brake plate 3 and the rotation axis of the wheel 2. In this embodiment, when the user presses down the pedal 13, the brake plate 3 rotates and engages with the groove 6 to achieve braking. When the user lifts the pedal 13 with their foot, the brake plate 3 rotates in the opposite direction, causing the braking structure to disengage from the groove 6, thereby releasing the brake on the wheel 2.

[0029] As a preferred embodiment, the brake structure is a locking post 7 that mates with the groove 6. The locking post 7 is radially positioned at one end of the brake plate 3, extending into the space enclosed by the end face of the wheel 2 and the annular wall 5. With this configuration, when the brake plate 3 rotates, it is possible to control whether the locking post 7 engages with the groove 6.

[0030] As a preferred embodiment, the brake plate 3 has an elastic plate 8 on its end face near the rotation axis of the wheel 2. The elastic plate 8 has two arc-shaped grooves 9 on its side facing the rotation axis of the wheel 2. The connecting line segment between the two arc-shaped grooves 9 is parallel to the end face of the wheel 2. The wheel seat 1 has an arc-shaped protrusion 10 that mates with the arc-shaped grooves 9. When the arc-shaped protrusion 10 is engaged in one arc-shaped groove 9, the engaging post 7 is engaged in the groove 6. When the arc-shaped protrusion 10 is engaged in the other arc-shaped groove 9, the engaging post 7 disengages from the groove 6. By providing the elastic plate 8, the rotation of the brake plate 3 can be restricted after rotation, thus ensuring that when the arc-shaped protrusion 10 is engaged in one arc-shaped groove 9, the engaging post 7 is engaged in the groove 6. Because there is a gap between the two arc-shaped slots 9, there must be an elastic plate 8; otherwise, the arc-shaped protrusion 10 cannot move from one arc-shaped slot 9 to the other arc-shaped slot 9 when the brake plate 3 rotates.

[0031] As a preferred embodiment, the distances from the two arc-shaped slots (9) to the rotation axis of the brake plate (3) are equal. This arrangement ensures that when the brake plate 3 rotates, the arc-shaped protrusion 10 can switch between the two arc-shaped slots 9.

[0032] As a preferred embodiment, the elastic plate 8 and the brake plate 3 are integrally formed, and a hollow structure 12 is provided between the two ends of the brake plate 3 and the elastic plate 8. By providing the hollow structure 12, when the brake plate 3 rotates to the point where the arc-shaped protrusion 10 abuts against the gap between the two arc-shaped slots 9, the gap between the two arc-shaped slots 9 can be pushed back, thereby allowing the arc-shaped protrusion 10 to move from one arc-shaped slot 9 into the other arc-shaped slot 9.

[0033] As a preferred method, such as Figure 5 As shown, an arc-shaped plate 11 is provided on the side of the wheel seat 1 facing away from the wheel 2. The center of the virtual circle B containing the arc of the arc plate 11 is located on the rotation axis of the brake plate 3. The identification mark 4 is provided on the raised surface of the arc plate 11. The plane containing the virtual circle B is parallel to the end face of the wheel 2. The pedal 13 is provided at the free end of the brake plate 3. The length of the connection between the brake plate 3 and the pedal 13 is greater than the center of the virtual circle B. The projection of the identification mark 4 on the axis of the wheel 2 is a straight line L15, and the projection of the pedal 13 on the axis of the wheel 2 is a straight line M14. The straight line L15 is located between the two ends of the straight line M14. The curvature of the pedal 13 is greater than the curvature of the identification mark 4. With this arrangement, the identification mark 4 is covered when the pedal 13 is pressed down, and exposed when the pedal 13 is lifted.

[0034] As a preferred embodiment, the identification mark 4 is a colored area coated on the raised surface of the curved plate 11. The colored area can be coated with a striking color such as red, yellow, or green, making it easy for the user to observe.

[0035] As a preferred embodiment, the identification mark 4 is a phosphor area coated on the raised surface of the curved plate 11. This phosphor coating allows the user to distinguish whether the brake is engaged even in low light conditions.

[0036] As a preferred embodiment, a support member 16 is provided on the lower surface of the end of the pedal 13 facing away from the wheel 2. When the brake plate 3 rotates to engage with the engaging pin 7 in the lower groove of the two grooves 6, the end of the support member 16 facing away from the pedal 13 is flush with the lowest point of the wheel 2. With this arrangement, when the brake plate 3 is in the braking state, the support member 16 is close to touching the ground, which can enhance the strength of the brake plate 3 and make it less likely to be damaged.

[0037] Preferably, the wheel 2 includes a first wheel piece 2-1 and a second wheel piece 2-2. The two wheel pieces are coaxially fixed on the rotation shaft of the wheel 2. The annular wall 5 is coaxially provided on the facing surfaces of the first wheel piece 2-1 and the second wheel piece 2-2, so that the wheel 2 has two sets of grooves 5. The brake plate 3 can be provided with two locking posts 7. Each locking post 7 cooperates with a set of grooves 5, thereby improving the braking effect.
