Description

The utility model relates to the field of computer technology and can be used to ensure the user's work with information input devices in dusty conditions.

Known design of the housing, the front part of which is equipped with a dust cover, made with the possibility of reciprocating movement, and the front wall of the dust cover is made rotary (see application US No. 4600247, IPC G11B 33/02, publication date 07.15.1986).

The disadvantage of this technical solution is the design of the dust cover, the rotation of the front wall of which can be impeded by both the input devices themselves and their wires and / or power cords.

Known protective cover for machines with a keyboard, made in the form of a transparent casing, open in front, which is permanently fixed to the machine body and located above the keyboard at a relatively low height (see application US No. 4449763, IPC G06F 3/02, publication date 22.05 .1984).

The disadvantages of this design are the following factors:

- low dustproof properties, because the cover is open at the front for operator's hand access;

- despite the transparency of the protective cover, it (especially in case of contamination) limits the operator's view;

- the location above the keyboard at a relatively low height and the stationary fastening of the transparent cover on the machine body limits the range and size of the keyboards used.

As the closest analogue, a casing for storing the keyboard is adopted, made in the form of a closed case with a rectangular bottom and a front wall, and in the cavity of the case, parallel to the bottom, with the possibility of reciprocating movement there is a base for information input devices equipped with a dust cover (see application US No. 4709972, IPC A47B 21/00; A47B 21/03; B41J5 / 10; G06F 1/16; G06F 3/02, publication date 12/01/1987).

The disadvantage of the closest analogue is the low efficiency of dust protection, because in the open state, when the base for the information input devices is maximally extended outward, the dust freely settles in the cavity of the casing, on the base and the information input devices, and it must be additionally removed.

The problem to be solved by the proposed utility model is the development of a casing design to protect information input devices from dust.

The technical result, which is achieved when solving the problem, is expressed in ensuring the degree of protection IP43 in accordance with GOST 14254-2015 for information input devices in the closed state of the case while expanding the functionality.

The problem is solved in that a casing for protecting information input devices from dust, made in the form of a closed housing with a rectangular bottom and a front wall, and in the cavity of the housing, parallel to the bottom, with the possibility of reciprocating movement, a base for information input devices is that the width of the base for information input devices does not exceed the width of the bottom, the front wall of the case is removable and oriented perpendicular to its bottom, and the lower part of the front wall is made in the form of flexible swiping elements, the free ends of which are adjacent to the base surface facing them, and the length of the flexible swiping elements are greater than the maximum height of the input devices.

Comparative analysis of the totality of essential features of the proposed technical solution and the totality of essential features of the prototype and analogues indicates its compliance with the "novelty" criterion.

In this case, the distinctive features of the utility model formula solve the following functional tasks.

The feature "the width of the base for information input devices does not exceed the width of the bottom" ensures the formation of a closed casing due to the fact that the front edge of the base, when closed, does not protrude beyond the front wall.

The feature "the front wall of the housing is made removable" expands the functionality, since it allows you to install the front walls with different lengths of flexible swiping elements.

The sign "the front wall of the case ... is oriented perpendicular to its bottom, and the lower part of the front wall is made in the form of flexible swiping elements" prevents dust from settling on the base and input devices by swiping it off with flexible elements during the reciprocating movement of the base.

The feature "the free ends [of the flexible swiping elements] abut the surface of the base facing them" allows dust to be swept off the base by means of the flexible elements while minimizing the gap between them.

The feature "the length of the flexible swiping elements is greater than the maximum height of the information input devices" provides free passage of the information input devices inside the housing.

Making the swiping elements flexible makes it possible to remove dust more efficiently (by increasing the area and contact time) without damaging or displacing the information input devices.

FIG. 1 shows a casing for protecting information input devices from dust when closed.

FIG. 2 shows a casing for protecting information input devices from dust when the base moves back and forth.

FIG. 3 shows a casing for protecting information input devices from dust when open.

FIG. 4 shows an electrical cabinet in which an enclosure is integrated.

The drawings show the body 1, its bottom 2 and front wall 3, base 4, input devices 5, flexible swiping elements 6.

The casing is made in the form of a closed body 1 with a rectangular bottom 2 and a front wall 3, which is removable and oriented perpendicular to the bottom 2.

In the cavity of the housing 1, parallel to the bottom 2, with the possibility of reciprocating movement, a base 4 for information input devices 5 is installed, the width of which does not exceed the width of the bottom 2.

The lower part of the front wall 3 is made in the form of flexible swiping elements 6, the free ends of which are adjacent to the surface of the base 4 facing them, and the length of the flexible swiping elements 6 is greater than the maximum height of the information input devices 5.

The claimed device operates as follows.

First, the casing is brought into the open state (see Fig. 3), for which the base 4 (see Fig. 2) is moved outward from the casing 1, then the information input devices 5 are installed and connected. To bring the casing into the closed state (see Fig. 2) . 1), the base 4 is moved inside the body 1.

Accordingly, the user opens the casing for the period of work with the information input devices 5, and the rest of the time the casing is in the closed state.

During the reciprocating movement of the base 4, the flexible swiping elements 6 of the front wall 3 come into contact with the surface of the base 4 facing them and the information input devices 5 and dust off them.

Thus, when the base 4 is moved outward from the housing 1, additional cleaning of the information input devices 5 from dust occurs, and when the base 4 is moved inside the housing 1, the flexible swiping elements 6 of the front wall 3 prevent dust from entering the cavity of the housing 1.

A keyboard, computer mouse, joystick, trackball, etc. can be used as input devices.

As a front panel with flexible swiping elements, you can use the brush plates to protect industrial metal cabinets from dust (for example, the dust protection brush plate - IP 43 for Altis cabinets from Legrand or brush bushing 60A-35-10-30BL for the S3000 series cabinets and F30, http://www.eurolan.com/ru/products/1579/5805).

If necessary, the bristles can be trimmed, thinned or thinned.

The authors developed design documentation, in which a steel sheet with a thickness of 1.5 mm was chosen as the material for the casing.

A flat brush with nylon (polyamide) bristles was used as the front wall with flexible swipers.

Individual brush hair thickness 0.25 mm, brush bristle layer thickness 3 mm, bristle length 60 mm.

Experiments were carried out with a brush, as a result of which the thickness of the bristle layer was reduced to 1.8 mm in order to reduce its stiffness.

This device can be integrated into the design of the control cabinet (see Fig. 4), for which the casing is fixed at the bottom, in this case the bottom of the control cabinet acts as the upper wall of the casing.
