Abstract

A tear-off roller comprising a casing and a sliding element fixed to the casing, which are complemented by rotation elements of the tear-off roller around the attachment point to household wheel equipment and fixation elements of the tear-off roller in a selected position. The tear-off roller can be attached to the wheel itself (to its hub (axis)) or to other elements of household wheeled equipment, for example, to a frame, to a frame, to a chassis or to a housing. The tear-off roller can move around the place of its attachment to household wheeled vehicles, including to such positions when the wheeled household wheeled wheel loses contact with the surface on which it is located. In cases where the wheel of household wheeled appliances loses contact with the surface on which the wheeled household appliances are located, and the support falls on the tear-off roller, the sliding element of the tear-off roller is in contact with the surface.

Description

Technical field

The utility model belongs to the class of devices that provide household wheeled vehicles (prams, shopping bags, bicycles, etc.) with the ability to move around on clean surfaces without contaminating these surfaces after this household wheeled equipment was operated on contaminated surfaces.

BACKGROUND: Movable wheel caps with sliding elements are similar to this device, utility model patent No.RU 167029.

The disadvantages of this type of device in comparison with the claimed utility model is the use of several sliding elements, which leads to an increase in the weight of the device and its fastening to the wheel axis of the household wheel equipment, which may not always be convenient to use due to the design features of the household wheel equipment.

Disclosure of utility model: The problem solved by this utility model is to provide a simple method of operating (moving) household wheeled equipment on clean surfaces without contaminating these surfaces after this household wheeled machinery has been operated on contaminated surfaces.

The essence of the technical solution lies in the possibility of changing the position of the tear-off roller relative to the wheel. As a result of this change (from the “above the wheel” to the “under the wheel” position), the support of household wheeled equipment is not on the wheel, but on the tear-off roller. In view of the fact that household wheeled equipment ceases to rest on the surface with wheels, the contact of the wheels with the surface on which the household wheeled equipment is stopped, and, consequently, the transfer of pollution from the wheel to a clean surface also ceases.

Diagrams 1 and 2 schematically show the various device variants of the utility model. In order to more fully and clearly disclose the operating principles of the utility model, one tear-off roller on one wheel is disclosed in the diagrams, although in reality household wheeled equipment can have a large number of tear-off rollers, in accordance with the number of wheels. The number, shape, size, inclination angles and relative position of the functional elements of the utility model shown in the diagrams may also differ from the actual ones, insofar as this does not impede the implementation of the functions of the utility model in general, and the functional elements of the utility model in particular. Thus, the number of variants of the device of a utility model is not limited only to those options that are shown in schemes 1 and 2. Schemes 1 and 2 are given in order to more fully disclose the principles of functioning of the utility model, for a faster and more complete understanding by a specialist of these principles.

Brief description of the schemes: Figure 1 (figures 1, 2, 3, and 4) shows one of the options for the tear-off roller device when the tear-off roller is attached to the wheel axis.

Under No. 1 in figures 1, 2, 3 and 4 shows the wheel. Under No. 2 in figures 1, 2, 3 and 4 shows the hub (axis) of the wheel. Under No. 3 in figures 1, 2, 3 and 4 shows the housing of the tear-off roller. Under No. 4 in figures 1, 2, 3 and 4, the sliding element of the tear-off roller is shown (the function of the sliding element can be performed by rollers, wheels, bearings, balls, etc.). The figure 1 shows the side view of this embodiment of the utility model when the tear-off roller is in the “above the wheel” position. Figure 2 shows the front view of this embodiment of the utility model when the tear-off roller is in the “above the wheel” position.

Figure 3 shows a side view of this embodiment of the utility model when the tear-off roller is in the “under the wheel” position. Figure 4 shows the front view of this embodiment of the utility model when the tear-off roller is in the “under the wheel” position.

Diagram 2 (figures 5, 6, 7, and 8) shows one of the options for the tear-off roller device, when the tear-off roller is attached to elements of the wheel equipment other than the axis on which the wheels are attached, for example, to the frame, frame, chassis, housing of the household wheeled techniques or to their elements. Under No. 1 in figures 5, 6, 7 and 8, the wheel is shown. Under No. 2 in figures 5, 6, 7 and 8 shows the hub (axis) of the wheel. Under No. 3 in figures 5, 6, 7 and 8 shows the housing of the tear-off roller. Under No. 4 in figures 5, 6, 7 and 8, the sliding element of the tear-off roller is shown (the function of the sliding element can be performed by rollers, wheels, bearings, balls, etc.). Under No. 5, figures 5, 6, 7 and 8 show a fragment of an element of a wheeled vehicle that is different from the axis of the wheel onto which a tear-off roller is mounted, for example, a fragment of a frame, frame, chassis or housing of a household wheeled vehicle. Figure 5 shows a side view of this embodiment of the utility model when the tear-off roller is in the “above the wheel” position. Figure 6 shows the front view of this embodiment of the utility model when the tear-off roller is in the “above the wheel” position.

Figure 7 shows a side view of this embodiment of the utility model when the tear-off roller is in the “under the wheel” position. Figure 8 shows the front view of this embodiment of the utility model when the tear-off roller is in the “under the wheel” position.

In view of the fact that the methods of rotation of the tear-off roller around the place of its attachment and the methods of its fixation in the selected position are not the essence of this utility model, in order to leave the schemes in a more convenient form for understanding the principles of operation of the utility model, the elements of the utility model for the rotation of the tear-off a roller around the place of its attachment to household wheeled vehicles, and elements of a utility model that secure the detachable roller in a selected position are not shown in the diagrams. The absence of these elements on the diagrams does not mean the absence of these elements on actual tear-off rollers. Tear-off rollers, supplemented by rotation elements around the attachment point to household wheeled equipment and fixing elements in the selected position, are variants of this utility model.

Utility Model Implementation

The principle of operation of the utility model is that the tear-off roller is attached to the wheeled vehicle in such a way that its rotation around the attachment point is allowed. When the tear-off roller rotates around the place of its attachment to household wheeled equipment, the element of household wheeled equipment changes, which this household wheeled vehicle relies on the surface. So, when the tear-off roller position “above the wheel”, the support of household wheeled vehicles is carried out on the wheel, and when the tear-off roller is “under the wheel”, the support of household wheeled vehicles is carried out on the tear-off roller, namely its sliding element. In view of the fact that the tear-off roller is equipped with a sliding element, when it is positioned “under the wheel”, household wheeled equipment can move along the surface without contact of its wheels with the surface. Thus, due to the fact that the wheel resting on the contaminated surface is replaced with a sliding element of the tear-off roller, the movement of household wheeled equipment on a clean surface does not entail pollution of this surface from the wheel.

The device includes:

- tear-off roller housing (No. 3 in schemes 1 and 2);

- sliding element of the tear-off roller (No. 4 in schemes 1 and 2);

- an element for the rotation of the tear-off roller around the place of its attachment to household wheeled vehicles (not shown in the diagrams, since this is not the essence of the utility model);

- an element for fixing the tear-off roller in the selected position (not shown in the diagrams, since it is not the essence of the utility model).

In diagrams 1 and 2, wheel number 1 is shown, wheel number (axis) is shown under number 2.

Diagram 2 under No. 5 shows a fragment of an element of a wheeled vehicle that is different from the axis of the wheel onto which a tear-off roller is mounted, for example, a fragment of a frame, frame, chassis or housing of a household wheeled vehicle.

The tear-off roller can be attached to the wheel itself (to its hub (axis)) and (or) to other elements of household wheel equipment other than the wheel hub (axis), for example, to the frame, to the frame, to the chassis or to the body of the household wheel equipment.
