Out TW 279516 Such a wheel block is known, which is equipped with a braking device. The wheel block includes the following components:

• - An inserted in the wheel block pivot axis, wherein a toothed disc is arranged at the bottom of the pivot axis;
• - A base frame consisting of a housing, a bearing block and a strut, which supports the bearing block eccentrically on the housing. The housing is connected at its head part by a pivotal connection with the pivot axis. The eccentric strut divides into an upper portion and a lower portion, the upper portion being connected to the lower portion of the housing deviating downward from the central axis line, while the lower portion is secured to the bearing block. In addition, the eccentric strut has on its inner side of the upper portion a transverse projection, while a raised rib is formed at an appropriate position of the lower portion;
• A foot pedal rotatably mounted on the housing;
• - An arcuate brake pad, which has at its front end a raised disc which is firmly clamped on the brake pad. In the middle portion of the brake pad, a recess is formed, which is placed on the projection of the eccentric strut during assembly, so that the brake pad can use the projection as a base in order to swing up and down can. At a suitable point in the rear portion of the brake pad at least one wing is formed;
• - A return spring which bears at one end at the bottom of the brake pad and at the other end to the raised rib of the eccentric strut; and
• - At least one cartwheel, which is rotatably mounted on the bearing block.

If the foot pedal is stepped down, the wing of the brake pad touches the cartwheel and creates a resistance. At the same time, the raised disc, which is firmly clamped to the front end of the brake pad, engages the clearance between the teeth on the toothed disc so that both the base frame and the carriage wheel stop turning. The above mentioned and in the TW 279516 However, the construction shown in the accompanying drawings is disadvantageous in practice because the bearing block is supported only on one side by an eccentric strut. To facilitate assembly, this construction has a hollowed-out condition on all other sides. If the wheel block is exposed to an external force, it can easily lead to the bearing block being crooked or broken.

From the TW 355823 is another wheel block with positioning and braking device is known, which consists of a wheel frame, a positioning assembly, a pivot assembly and a wheel assembly. The wheel frame has a main body on which a through-hole and a recess are formed, wherein the pivoting group are installed in the through-hole and the positioning assembly in the recess. Centered on the lower part of the base body, a bearing opening is formed, in which the wheel assembly is installed and stored. The pivot assembly, consisting of a pivot pin, a mounting piece, an upper bearing and a lower bearing is disposed in the through hole of the wheel frame. The wheel assembly, which consists of a pair of wheels and a wheel axle, is attached to the side of the wheel frame. Because the wheels are mostly made of plastic, reinforcing side plates extending from the bearing opening to the top are attached to both sides of the wheel frame. The disadvantage of this solution is that the pivot assembly and the positioning are installed during assembly only from the free space below the bearing axis, which complicates the assembly.
