Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a floating brake pedal. Background Art

[0002] With the continuous improvement of living standards, people are paying more and more attention to the impact of furniture on children. High-quality children's furniture that meets parents' psychological expectations often gains more market share. Therefore, based on user feedback, product updates and iterations are very necessary. In order to make it more suitable for children, manufacturers have developed a children's chair with rollers to facilitate the movement of the children's chair. However, parents hope that the rollers on the children's chair can be locked when the child is sitting in the children's chair or when sitting on and getting up to improve safety. Therefore, manufacturers choose brake wheels as rollers. Specifically, there are at least two brake wheels on the children's chair, which are generally set on the two front legs of the children's chair. When locking, both brake wheel switches need to be stepped on. When unlocking, both brake wheel switches need to be lifted up, which is inconvenient to operate. What's more troublesome is that you even need to squat down and use your hands to pry the switch to unlock.

[0003] Moreover, the cost of brake wheels is high. Compared with ordinary universal wheels, the cost of a single brake wheel is 4-8 times that of ordinary universal wheels. The high cost greatly reduces the manufacturer's profit. Moreover, when the brake wheels are replaced during after-sales service, the cost is further increased.

[0004] In addition, since the legs of the children's chair are horizontal and the brake wheel is set under the legs, the protruding switch of the brake wheel interferes with the legs when the brake wheel turns. Once the interference occurs, the other rollers are oriented differently from the brake wheel, and the children's chair cannot be moved. Therefore, a positioning pin is required on the brake wheel to limit the rotation range of the brake wheel. In short, the brake wheel is different from the ordinary universal wheel. It cannot achieve 360° rotation. Therefore, the brake wheel can only move the children's chair in a straight line, and it is difficult to make the children's chair rotate. The movement of the children's chair becomes very rigid.

[0005] It can be seen from this that using brake wheels on children's chairs is not a preferred solution. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems, the utility model provides a floating brake pedal, including a base, a brake component and a footrest, the base including a mounting seat located at the front, a roller being provided under the base, the footrest being floated on the mounting seat and linked with the brake component; in the use state, the footrest is subjected to a downward force due to the resting of the human foot, at which time the footrest floats downward on the mounting seat, and the brake component also moves downward in linkage until its lower end is pressed against the ground to prevent the roller from rolling; in the movable state, the foot is withdrawn, the footrest floats upward due to the disappearance of the downward force, the brake component moves upward and becomes empty, and the roller can continue to roll; the pedal not only has a footrest function, but also has a brake and anti-skid function, and the roller no longer needs to use a brake wheel, only an ordinary universal wheel is required.

[0007] The technical solution of the present utility model is achieved as follows:

[0008] A floating brake pedal comprises a base, a footrest and a brake component, a roller is provided under the base, the base comprises a mounting seat located in the front part thereof, the footrest is floatingly arranged on the mounting seat, and the footrest and the brake component are arranged in linkage; the pedal has a use state and a movable state, in the use state, the footrest is subjected to a downward force and floats downward on the mounting seat, the brake component is linked with the footrest, the brake component moves downward to the lower end and presses down on the ground to prevent the roller from rolling; in the movable state, the downward force on the footrest disappears, the footrest floats upward on the mounting seat, the brake component moves upward accordingly and becomes airborne, and the roller can roll.

[0009] This type of footrest is mainly used in children's chairs. When in use, the child sits on the children's chair with his feet resting on the footrest. At this time, the downward floating brake part presses down on the ground to generate friction to prevent the rollers from rolling and causing the children's chair to move, thereby providing stability for the child's sitting; the implementation method and structure are both simpler.

[0010] The footrest not only has the function of resting the feet, but also has the function of braking and anti-skidding. In this way, the braking and anti-skidding function of the brake wheel is replaced. The roller no longer needs to use a brake wheel, and only an ordinary universal wheel is needed. The advantages are: first, the cost is greatly reduced, which improves the manufacturer's efficiency; second, the operation of locking and unlocking the brake is more convenient, and there is no need to stand up or bend over to operate. You only need to step on the footrest to brake, and you can unlock it by leaving the footrest; thirdly, the interference problem between the brake wheel and the base is solved, which makes the steering of the roller flexible and the children's chair more flexible when moving.

[0011] Preferably, the mounting seat is provided with a through hole extending from top to bottom; the brake member is arranged downwardly below the footrest, and the brake member is vertically arranged in the through hole; an elastic member is provided between the footrest and the mounting seat, and the elastic member is configured to always give the footrest an upward elastic force; the footrest and the brake member are floatingly arranged on the mounting seat through the elastic member. The brake member is directly connected to the footrest, and the two can also be formed in one piece, so as to realize the linkage between the brake member and the footrest; of course, a transmission mechanism, such as a connecting rod, can also be provided between the brake member and the footrest to realize the linkage between the two; when switching from the movable state to the use state, the user's foot rests on the footrest, the footrest is subjected to a downward force, the elastic member is deformed, and the footrest and the brake member float downward together; when switching from the use state to the movable state, the footrest is released, the elastic member drives the footrest to reset, and the footrest is free again.

[0012] Preferably, the mounting base is provided with a vertical sleeve, the through hole being formed in the sleeve. The sleeve protrudes upward and downward from the mounting base, with the lower end of the sleeve being free; in use, the brake member protrudes downward from the sleeve. Since the sleeve is free, braking and anti-skid function is not possible. Therefore, the through hole is formed through the sleeve, allowing the brake member to protrude from the sleeve below the through hole and contact the ground. The brake member is pressed down on the ground to brake and prevent skid.

[0013] Preferably, the sleeve is provided with a stopper that protrudes from the sleeve toward the interior of the through hole, and the brake member is provided with a stopper groove into which the stopper is inserted. The stopper and the stopper groove serve to limit the floating travel of the brake member and the footrest, preventing the brake member and the footrest from floating excessively and also preventing the brake member from being separated from the sleeve. When the brake member floats, the stopper changes position within the stopper groove.

[0014] Preferably, a gap is provided between the upper end of the sleeve and the footrest. In this embodiment, the gap between the upper end of the sleeve and the footrest varies from 5.5 to 15.5 mm, i.e., when in use, the gap is 5.5 mm, and when movable, the gap is 15.5 mm. The difference of 10 mm between the two represents the travel of the brake member and the footrest, which is related to the dimensions of the stop member and the stop slot.

[0015] Preferably, the number of the brake member and the number of the sleeve are both two, and the two sleeves are arranged on the mounting base at intervals on the left and right sides. The number of the brake member and the number of the sleeve are both two to further increase the stability of the footrest on the mounting base.

[0016] Preferably, the brake member is a columnar tubular member, and a friction pad is provided on the lower end surface of the brake member. When the brake member brakes to prevent slipping, the friction pad below it contacts the ground, which increases friction on the one hand and prevents the brake member from wearing the floor and the wear of the brake member on the other hand.

[0017] As a preference, the travel between the brake member and the footrest is 8-15 mm. In this solution, the travel is 10 mm, which is short, giving the user a small floating feeling and no sense of disobedience.

[0018] Preferably, the elastic member is a spring, which is sleeved on the brake member; an annular boss is provided on the inner wall of the through hole, the lower end of the spring abuts against the boss, and the upper end of the spring abuts against the footrest.

[0019] Preferably, the mounting base is fixedly connected to the base, and the two are fixedly connected by screws.

[0020] The design starting point, concept and beneficial effects of the utility model using the above technical solution are:

[0021] This type of footrest is mainly used in children's chairs. When in use, the child sits on the children's chair with his feet resting on the footrest. At this time, the downward floating brake part presses down on the ground to generate friction to prevent the rollers from rolling and causing the children's chair to move, thereby providing stability for the child's sitting; the implementation method and structure are both simpler.

[0022] When switching from the movable state to the use state, the user's feet are placed on the footrest, the footrest is subjected to downward force, the elastic part is deformed, and the footrest and the brake part float downward together; when switching from the use state to the movable state, the footrest is released, the elastic part drives the footrest to reset, and the footrest is empty again.

[0023] The footrest not only has the function of resting the feet, but also has the function of braking and anti-skidding. In this way, the braking and anti-skidding function of the brake wheel is replaced. The roller no longer needs to use a brake wheel, and only an ordinary universal wheel is needed. The advantages are: first, the cost is greatly reduced, which improves the manufacturer's efficiency; second, the operation of locking and unlocking the brake is more convenient, and there is no need to stand up or bend over to operate. You only need to step on the footrest to brake, and you can unlock it by leaving the footrest; thirdly, the interference problem between the brake wheel and the base is solved, which makes the steering of the roller flexible and the children's chair more flexible when moving.

[0035] The specific implementation of the utility model is as follows:

[0036] like Figure 1-5As shown, the utility model provides a floating brake pedal, including a base 1 and a footrest 2, the base 1 includes a mounting seat 3 located at the front thereof, and the mounting seat 3 is provided with a through hole 4 that passes through from top to bottom; a downwardly extending brake member 5 is provided on the footrest 2, and the brake member 5 is vertically arranged in the through hole 4, and an elastic member is provided between the footrest 2 and the mounting seat 3, and the elastic member is configured to always give the footrest 2 an upward elastic force; the footrest 2 and the brake member 5 are floatingly arranged on the mounting seat 3 through the elastic member; a roller 7 is provided under the base 1, and the mounting seat 3 is vacant; the pedal has a use state in which a human foot is placed on the footrest 2 and a movable state in which it can be moved by the roller 7; in the use state, the footrest 2 and the brake member 5 float downward on the mounting seat 3 due to the weight of the human foot, and the lower end of the brake member 5 is pressed down on the ground to prevent the roller 7 from rolling; in the movable state, the human foot leaves the footrest 2, the brake member 5 is vacant due to the elastic force of the elastic member, and the roller 7 can roll.

[0037] This type of footrest is mainly used in children's chairs. When in use, the child sits on the children's chair with his feet resting on the footrest 2. At this time, the downward floating brake member 5 presses down on the ground to generate friction to prevent the roller 7 from rolling and causing the children's chair to move, thereby providing stability for the child's sitting; the implementation method and structure are both simpler.

[0038] When switching from the movable state to the use state, the user's feet are placed on the footrest 2, the footrest 2 is subjected to a downward force, the elastic member is deformed, and the footrest 2 and the brake member 5 float downward together; when switching from the use state to the movable state, the footrest is released, the elastic member drives the footrest 2 to reset, and the footrest 2 is empty again.

[0039] The footrest 2 not only has a footrest function, but also has a brake and anti-skid function. In this way, the brake and anti-skid function of the brake wheel is replaced. The roller 7 no longer needs to use a brake wheel, and only an ordinary universal wheel is needed. The advantages are: first, the cost is greatly reduced, which improves the manufacturer's efficiency; second, the operation of brake locking and unlocking is more convenient, and there is no need to stand up or bend over to operate. You only need to step on the footrest 2 to brake, and you can unlock the car by leaving the footrest 2; thirdly, the interference problem between the brake wheel and the base 1 is solved, so that the roller 7 can be turned flexibly, and the children's chair is also more flexible when moving.

[0040] Specifically, if Figure 1 、 6As shown in Figure 7, the mounting seat 3 is fixedly connected to the base 1, and the two are fixedly connected by screws, or the two can also be integrally formed; the elastic member is a spring 6, and the brake member 5 is a columnar pipe; a vertical sleeve 8 is provided on the mounting seat 3, and the sleeve 8 is a hollow cylinder with an inner diameter larger than the diameter of the brake member 5. The through hole 4 is opened on the sleeve 8, and the sleeve 8 is open both above and below; the sleeve 8 protrudes from the mounting seat 3 upward and downward, that is, the upper end of the sleeve 8 is higher than the upper surface of the mounting seat 3, the lower end of the sleeve 8 is higher than the lower surface of the mounting seat 3, and the lower end of the sleeve 8 is empty, that is, the lowest point of the sleeve 8 is higher than the ground, so that when the brake member 5 is not braking, The children's chair can move smoothly; the brake component 5 is inserted into the sleeve 8, and in the use state, the brake component 5 protrudes downward from the sleeve 8 to contact the ground; since the sleeve 8 is empty, it is impossible to brake and prevent slipping, so the through hole 4 is passed through the sleeve 8, so that the brake component 5 can protrude from the sleeve 8 from below the through hole 4 and contact the ground, and the brake component 5 is pressed down on the ground to prevent slipping; the number of the brake components 5 and the sleeve 8 are both two, and the two sleeves 8 are arranged at intervals on the mounting base 3, and the two brake components 5 are arranged at corresponding intervals and fixedly set below the footrest 2 to further increase the stability of the footrest 2 on the mounting base 3.

[0041] The spring 6 is sleeved on the brake member 5 , and an annular boss 9 is provided on the inner wall of the through hole 4 . The lower end of the spring 6 abuts against the boss 9 , and the upper end of the spring 6 abuts against the footrest 2 , thereby providing an upward elastic force for the footrest 2 .

[0042] In order to increase the braking and anti-skid effect, a friction pad 10 is provided on the lower end surface of the brake component 5. When the brake component 5 brakes and stops skidding, the friction pad 10 below it contacts the ground, which on the one hand increases the friction force, and on the other hand prevents the brake component 5 from wearing the floor and itself.

[0043] A limit piece 11 is provided on the sleeve 8, and the limit piece 11 protrudes from the sleeve 8 toward the inside of the through hole 4. A waist-shaped limit groove 12 is provided on the brake member 5, and the limit piece 11 is inserted into the limit groove 12; the limit piece 11 and the limit groove 12 are used to limit the floating stroke of the brake member 5 and the footrest 2 to prevent the brake member 5 and the footrest 2 from floating too much, and also to prevent the brake member 5 from being detached from the sleeve; when the brake member 5 floats, the limit piece 11 changes its position in the limit groove 12; the limit piece 11 is a screw with a knob. During installation, the brake member 5 is first inserted into the sleeve 8, and then the limit piece 11 is tightened to the sleeve 8, and the end of the screw is inserted into the limit groove 12.

[0044] There is a gap between the upper end of the sleeve 8 and the footrest; the stroke of the brake member 5 and the footrest 2 is 8-15mm; in this solution, the gap between the upper end of the sleeve 8 and the footrest changes from 5.5 to 15.5mm, that is, in the use state, the gap is 5.5mm, and in the movable state, the gap is 15.5mm. The difference of 10mm between the two is the stroke of the brake member 5 and the footrest 2, which is related to the size of the limit member 11 and the limit groove 12; and the shorter the stroke, the less floating feeling given to the user, and no sense of incongruity.
