Description

Casters

This invention relates to a caster, and in particular to an improvement in the technical structure of a caster with a braking function.

Generally, casters with braking function are also provided with a brake plate that can be pressed on the wheel body by pushing. A pedal is also installed on the housing. When the pedal is swung downward, the pedal can push the brake plate against the wheel body to brake. When the pedal is swung upward, the brake plate will not be pushed against the wheel body, and the wheel body can rotate.

However, when the pedal is to be swung upward, for convenience, the user will use the back of the foot to hook the pedal upward from the bottom, which is easy to scratch the leather shoes or the toes or the back of the foot. In addition, the upward or downward swinging feature of the pedal is not observed, which often results in the staff being unable to effectively confirm whether the caster is in a braking state, which easily causes safety concerns in the working environment, and there is a shortcoming that needs to be improved urgently.

Therefore, it is necessary to provide a novel and advanced caster to solve the above-mentioned problems.

The main purpose of this invention is to provide a caster that can be stepped on from top to bottom when braking or releasing the brake, and the caster can effectively provide an indication of the braking state.

To achieve the above-mentioned purpose, the invention provides a caster, including a housing, a brake, a first pedal, a marking portion and a second pedal. The housing is provided with a wheel body, and the wheel body rotates around an axis. The brake is swingably arranged on the housing. The first pedal is arranged on the housing and can be swingably arranged between a first position and a second position, and the first pedal includes a first pedaling end and a top-butting portion. The marking portion is arranged on a side of the first pedal away from the wheel body. The second pedal includes a second pedaling end, which is swingably arranged on the housing. When the first pedal is located at the first position, the second pedal covers the portion of the first pedal provided with the marking portion, the first pedaling end is far away from the wheel body, and the brake member is not in contact with the wheel body; when the first pedal swings toward the second position, the first pedaling end swings toward the wheel body, the first pedal abuts against the brake member to cause the brake member to swing and abut against the wheel body, the abutting portion drives the second pedal to swing so that the first pedaling end and the second pedaling end swing away from each other, and the second pedal does not cover the marking portion so that the marking portion is exposed.

The following is merely an example to illustrate possible implementations of the present invention, but it is not intended to limit the scope of protection for the present invention, so it should be stated in advance.

Please refer to Figures 1 to 7, which show a preferred embodiment of the present invention. The caster of the present invention includes a housing 1, a brake member 2, a first pedal 3, a marking portion 4 and a second pedal 5.

The housing 1 is provided with a wheel body 11 , and the wheel body 11 rotates around an axial direction 12 .

The brake member 2 is movably disposed on the housing 1 .

The first pedal 3 is disposed on the housing 1 and can be swung between a first position and a second position. The first pedal 3 includes a first pedaling end 31 and a top-butting portion 32 .

The marking portion 4 is disposed on a side of the first pedal 3 away from the wheel body 11 .

The second pedal 5 includes a second pedal end 51 movably disposed on the housing 1 .

When the first pedal 3 is in the first position, the second pedal 5 covers the portion of the first pedal 3 where the marking portion 4 is provided, the first pedal end 31 is far away from the wheel body 11, the brake member 2 is not in contact with the wheel body 11 (as shown in FIG. 1 and FIG. 5 ), the wheel body 11 can rotate arbitrarily, and the marking portion 4 is covered by the second pedal 5 and cannot be viewed from the outside, so that it can be known that the caster is in a rotating state; when the first pedal 3 is swung toward the second position, the first pedal end 31 When the caster 10 is swung toward the wheel body 11, the first pedal 3 abuts against the brake member 2 so that the brake member 2 is swung and abuts against the wheel body 11, and the abutting portion 32 drives the second pedal 5 to swing so that the first pedaling end 31 and the second pedaling end 51 are swung away from each other, and the second pedal 5 is not covered by the marking portion 4 so that the marking portion 4 is exposed (as shown in FIGS. 2 and 6 ). The marking portion 4 can be seen from the outside, which can effectively remind the outside world that the caster is in a braking state, and can have a better safety reminder function.

When the caster is to be restored to the rotating state (i.e., the first pedal 3 is to be reset to the first position), the second pedal end 51 only needs to be stepped on in the direction of the first pedal end 31, the second pedal 5 presses against the top portion 32, and the first pedal 3 is restored to the first position. Therefore, the invention is convenient and simple to operate. When braking or releasing the brake, the action of stepping from top to bottom is used to avoid scratching the shoe surface or skin.

The marking portion 4 includes a receiving groove 41 recessed in the first pedal 3 and a marking member 42 . The marking member 42 is installed in the receiving groove 41 . The color of the marking member 42 is different from the color of the first pedal 3 to achieve a striking reminder effect.

Specifically, a spring sheet 21 is protruded from one end of the brake member 2 facing upward, and the spring sheet 21 bounces against the top of the housing 1 so that the spring sheet 21 normally swings toward the first pedal 3. Therefore, when the first pedal 3 is in the second position and the second pedal end 51 is stepped on in the direction of the first pedal end 31, the spring sheet 21 drives the brake member 2 to bounce toward the first pedal 3, thereby driving the first pedal 3 to bounce toward the first position, thereby achieving a labor-saving effect. It is worth mentioning that the marking member 42 protrudes from the accommodating groove 41. When the first pedal 3 is located at the first position, the second pedal 5 abuts against the marking member 42 (as shown in FIG. 7 ). Therefore, when the first pedal 3 bounces toward the first position, the marking member 42 can provide noise reduction and shock absorption effects. In this embodiment, the marking member 42 is a rubber member, which can provide better noise reduction and shock absorption effects. In other embodiments, it can also be a plastic member or other material with a hardness lower than that of metal.

The brake member 2 is pivoted to the housing 1 via a first pivot 61, the extension direction of the first pivot 61 is parallel to the axial direction 12, the first pedal 3 is pivoted to the housing 1 via a second pivot 62, the second pivot 62 is located between the first pedaling end 31 and the abutting portion 32, so that the first pedaling end 31 and the abutting portion 32 form a warping plate manner to swing.

The abutting portion 32 is pivotally connected to the second pedal 5 by a third pivot 63. The second pedal 5 is provided with two spaced coupling portions 52 on one side facing the first pedal 3. The third pivot 63 is inserted into the two coupling portions 52, thereby the abutting portion 32 is linked to the second pedal 5.

The second pedal 5 further includes a sliding end 53, and the two coupling parts 52 are located between the sliding end 53 and the second pedaling end 51. The sliding end 53 is slidably arranged to abut against the shell 1, so that the second pedal 5 slides and swings relative to the shell 1, and the first pedaling end 31 and the second pedaling end 51 can be moved away from each other with a larger swing range to avoid the second pedal 5 covering the marking part 4 when the first pedal 3 is in the second position, and the second pedal 5 can push the first pedal 3 to return to the first position with less effort.

The housing 1 includes two side walls 13 and a top wall 14. The top wall 14 is connected between the two side walls 13. The wheel body 11 is pivoted between the two side walls 13. The brake member 2 is located between the wheel body 11 and the top wall 14. The top wall 14 is concavely provided with a groove 15. The two sides of the groove 15 are respectively provided with a stopper 16. The sliding end 53 A pin 54 is inserted through the groove 15, and the sliding end 53 is accommodated in the groove 15. The top wall 14 is further provided with a baffle 17 spaced apart from the two limit baffles 16. The pin 54 crosses the groove 15 and is slidably disposed between the two limit baffles 16 and the baffle 17 to prevent the pin 54 from detaching from the housing 1, thereby limiting the sliding range of the sliding end 53.
