SHOE SOLE CLEANER

The sole sole cleaning device is used to remove dirt from the shoes when entering the 5 buildings.

Carpets and grilles have been commonly used to remove dirt from shoes. Brushing devices have been developed for more efficient cleaning. They either require connection to an external energy source or are based on the exploitation of a person’s weight to produce a scattering motion. The problem with models based on the utilization of a person's weight is the large force required for the operation of the 10 diverting devices. They are based on a solution model in which, by pressing the foot in connection with brushing, a spring is tuned, which performs the return movement of brushing. During the return movement, the energy stored by the spring is needed to raise the mass of the moving parts of the equipment to the initial position and to overcome the internal friction of the equipment. The spring force increases with the pressure of the foot, being at its maximum in the extreme position. To ensure operation 15, the springs must also be pre-tensioned, which increases the total force required during brushing. For lighter brush users, there is not enough power and the range of motion of the brush is insufficient.

The device now invented is based on the utilization of a person's weight. The shoe sole cleaning device according to the invention is characterized by what is stated in claim 20 1.

In the device, the brushes are placed in separate puppies at the ends of the rocker arms. By using the rocker arms, the energy required for the return movement of the brush is obtained in connection with the brushing of the shoe directly from the person's weight without energy storage mechanisms. The pedals balance each other's weight, so during brushing, in addition to the friction 25 of the equipment, only the energy used for brushing in the brushes resists movement. Compared to previous brush device models, less power is required to operate the device and the brush device works even under light conditions.

The invention will now be described in detail with reference to the drawings.

Figure 1 shows rocker arms 2 96575 (6) articulated to the body part (1) of a shoe sole cleaning device, the ends of which are articulated with lattice (2) pedals (5). The push rods (4) are articulated to the body and the brushes (3). When the pedals are moving vertically up and down in opposite directions to each other, the push rods are forced to make the brushing movement back and forth 3 horizontally, guided by the slots (7) at the ends of the pedals.

Drawing 2 shows how the brushing movement can be made more efficient by moving the brushes (3) in addition to the horizontal movement. The rotational movement is provided by the teeth (8) on the calves by means of gears (10) attached to the brush shafts (9).

Claims (4)

3,96575 Shoe sole cleaning device comprising a body part (1), gratings (2) and shells (3) under the gratings, characterized in that the brushes (3) are arranged in recesses (5) 5 which reciprocate vertically under the effect of the weight of the user the rocker arms (6) articulated to the body in opposite directions on each other and the brushes are associated with a mechanism for displacing them. Cleaning device according to Claim 1, characterized in that when the calves 10 move vertically, the sticks (3) move horizontally by means of push rods (4) which are articulated to the body (1). Cleaning device according to Claim 2, characterized in that, when the calves move vertically, the brushes (3) make a rotational movement about their axis (9) by means of teeth (8) in the calipers and gears (10) attached to the axes of the brushes. «4 96575
