Embodiment 1

[0037] In the caster with brake according to Embodiment 1 of the present invention, the brake of the elongated U-shaped elastic resin member is installed horizontally at the position directly above the tire of the left and right arms of the fork that holds the wheel rotatably with the axle. Pushing the operation portion at the tip downward causes the friction portion to enter between the arm of the fork portion and the tire to pinch the tire to prevent rotation.

[0038] exist Figure 1 ~ Figure 3 Among them, the wheel 10 is a grounded rotating component composed of a tire and a hub. The tire 11 is a tire made of urethane resin. The hub 12 is a plastic rim that doubles as a bearing. The axle 13 is a member that rotatably supports the wheel. The fork 14 is a member that holds the wheel via the axle. The bearing 15 is a bearing that supports the rotating shaft. The rotation shaft 17 is the rotation center axis of the fork. The caster mounting plate 20 is a base plate for h...

Embodiment 2

[0048] In the caster wheel with brake according to the second embodiment of the present invention, a slender U-shaped spring with different left and right lengths is installed horizontally at the position directly above the tire of the left and right arms of the fork that holds the wheel rotatably with the axle. The brake of the metal part pushes the operation part at the tip downward so that the friction part enters between the arm of the fork part and the tire and pinches the tire to prevent rotation.

Abstract

A castor wheel with a brake, a wheel (10) composed of a tire (11) and a hub (12) is held rotatably by a fork (14) through an axle (13). Use bearing (15) and rotating shaft (17) to keep fork (14) into rotatable castor mounting plate (20) and be installed on the luggage etc. A stopper (30) made of elongated U-shaped elastic resin member is mounted horizontally directly above the tires (11) of the left and right arms of the fork (14). As long as it is not operated, the brake (30) returns to a stable horizontal state and does not inadvertently prevent the rotation of the wheel (10). If the operation part (31) at the top end of the brake (30) is operated, and the friction part (33) at the center of the brake (30) enters between the arm of the fork (14) and the tire (11), the tire ( 11) to stop the wheel (10) from rotating. The present invention can prevent the rotation of the tire of the caster with a simple structure, light weight, and low-cost brake.

Description

technical field [0001] The invention relates to a caster wheel with a brake for luggage, in particular to a caster wheel with a brake with simple structure, light weight and low cost. Background technique [0002] Conventionally, various types of casters with brakes for bags have been developed. Figure 9 In the casters shown in (a) and (b), when the rod member in the caster housing is lowered, the brake pawl is embedded in the concave portion of the rim of the wheel to prevent the wheel from rotating. Figure 9 In the casters shown in (c) and (d), when the lever member provided on the fork of the caster is rotated and lowered, the brake pawl is embedded in the concave portion of the wheel rim to prevent the wheel from rotating. Hereinafter, some examples of conventional technologies related to this will be given. [0003] The "brake device for caster wheels" disclosed in Patent Document 1 can freely adjust the braking force on the caster wheels. Such as Figure 9 As shown ...
