Description

Technical field

The utility model refers to a tool for cleaning smooth surfaces and is used in everyday life.

BACKGROUND OF THE INVENTION

It is known from WO 2009/097531 (A1) a tool for cleaning smooth surfaces consisting of a housing closed with a lid that is fixed to the housing by means of pins located therein and inserted into openings formed on the lid. There is an inner groove in the body volume in which a knife is inserted in the safety element. On the front, the sides of the lid and housing are slanted. The safety element is made in the form of a clamp, with plastic hinges in which the blade is placed. The walls of the blade have rectangular openings to accommodate the retaining pins, and the rectangular openings determine the stroke and the possibility of the safety element slipping into the groove of the housing. By sliding the safety element with the blade into the groove, two positions of the tool are made, respectively working, whereby the cutting edge of the blade is out of the housing and the lid and the non-working position in which the blade is completely located in the housing and the lid. For ease of use with the tool on the lid there is an embossed shaped section. Through it, the user is able to release the blade of the blade outside the housing in its working position by pushing the cap forward and back to retract the blade into the housing in the idle position.

When working with the tool, which is related to the opening and closing of the safety element, as well as moving it back and forth in the working and non-working position, the tool comes out of use faster and breaks the hinges, since they are made of plastic material and over time, they lose their flexibility.

The technical nature of the utility model

The task of the utility model is to create a tool for cleaning smooth surfaces that is simple, functional, convenient and safe, both when working with it and when carrying it, as well as quickly and easily. performs replacement of the worn blade.

The problem is solved by means of a tool for cleaning of smooth surfaces, including the housing and the lid, with the inside of the housing a groove at the bottom of which are formed pins, arranged in two rows for fixing a knife in two positions, working and non-working position. There are openings on the lid for receiving the pins, with the lid closed, which is tightly seated in the groove of the housing.

For convenience of gripping the tool on the outer surface of the lid there is a shaped relief section. Immediately adjacent to the retaining pins, the exterior side of the housing and the lid are slanted, whereby an oblique edge is formed through which, in a working position, the cutting edge of the blade extends between the housing and the lid outside. On both sides of the inner groove, the housing extends in shaped elastic wings, inside which there are shaped sockets, both front and rear.

On the housing wall opposite to the bevelled edge there is a shaped notch providing open access for gripping the lid when opening it. There is an opening in the notch area on the lid that is required to hang the tool. There are teeth on either side of the notch on the sides of the lid and on the housing, forming a peripheral serrated wash, with a lateral serrated portion on the side wall of one chord, and a tapered tapered tapered side wall of the other wing.

In one embodiment of the instrument, the closed-lid housing is in the form of a low prism, with a trapezoidal base on which the large base is an arch projecting outwards, the bevelled edge being formed on the walls of the prism on the small base, and the cutout with the peripheral notched portion being formed on the walls of the prism from the large base.

In another embodiment of the instrument, the housing and the lid fitted thereto are formed by a rectangular prism.

Explanation of the annexed figures

The utility model is explained in more detail by the accompanying figures, where:

1326 Ul figure 1 is an axonometric view of the instrument;

Figure 2 is a side view of the A tool;

Figure 3 is a side view of the B tool;

Figure 4 is an axonometric view of the housing, with the lid open, with the two positions of the blade;

Figure 5 is an axonometric view of the lid.

Examples of implementation of the utility model

As shown in Figures 1,4 and 5, the tool for cleaning smooth surfaces includes a housing 1 and a lid 2, with a groove 14 in the volume of the housing 1, at the bottom of which there are two pins 6 arranged in two fixing rows. on blade 3 in two positions, working and non-working position. There are openings 7 on the lid 2 for receiving the pins 6, with the lid 2 closed, so that the lid 2 is firmly in the groove 14.

For convenience of gripping the tool on the outer surface of the lid 2 there is a shaped relief section 9. Immediately adjacent to the locking pins 6, the walls are slanted on the outside of the housing 1 and of the lid 2, whereby an oblique edge 12 is formed through which position of the blade 3, its cutting edge extends beyond the housing 1 and the lid 2. On the two sides of the inner groove 14, the housing 1 extends in shaped elastic wings 4, inside which there are shaped sockets 5, both on their front and rear parts.

On the wall of the housing 1, located opposite to the beveled edge 12, there is a shaped notch 15, which provides free access for gripping the lid 2 when it is opened. In the area of the notch 15 on the lid 2 there is an aperture 10 necessary to hang the tool. On both sides of the recess 15, there are teeth on the walls of the lid 2 and the housing 1, forming a peripheral notched portion 11, with a lateral serrated portion 13 on the side wall of one wing 4, and a pointed tapered projection on the side wall of the other wing 4. lane 8.

Additional peripheral cleaning opportunities are created through the peripheral toothed section 11 and the tapered tapered belt 8.

In one embodiment of the instrument, the housing 1 with the lid closed 2 is in the form of a low prism, with a trapezoid base on which the large base is an arch projecting outwards, the bevelled edge 12 being formed on the walls of the prism on the small base, and the recess 15, with the peripheral notched portion 11 are formed on the walls of the prism from the large base.

In another embodiment of the instrument, the housing 1 and the lid 2 fitted thereto are formed in the form of a rectangular prism.
