An anti-dust chamber for performing work with hand tools and other devices can be made in one of two types:

Type I. Anti-dust chamber with a rigid body.

In this type, the front wall (1), the side walls (2), the lower part of the body (3) and the rear wall (4) are held together by rigid joints, which can be in the form of bolts, screws, rivets, welded joints, etc. or are made in the form of a monolithic structure, for example, by melting. The transparent top (5) and the transparent wall (6) also look like a rigid connection.

Type II. Anti-dust chamber with a folding body (useful for households in the absence of sufficient space to accommodate the anti-dust chamber).

In this type, the front wall (1), the lower part of the body (3), the back wall (4), the transparent top (5) and the transparent wall (6) are connected using movable joints, which are hinges (furniture), ropes or other structure , and the side walls (2) predominantly have no movable connections with other elements and are connected to them by means of “quick-detachable”, i. e. connections that do not have increased complexity and do not require a lot of time. These connections can be made in the form of clamps, locks, magnetic fasteners.

It should be noted that depending on the modification of the dust chamber and the method of its folding, the method of connecting the elements may change. So, the side walls (2) in some modifications may have movable joints with other elements, or there may be no movable joints at all, which will lead to the folding of the dust chamber with its preliminary disassembly into components that will fit in the required way, and the fastening of the housing elements will be be made exclusively with the help of "quick-release".

Within the framework of this invention, a description of the folding of the anti-dust chamber is proposed, the body elements of which (with the exception of the side walls (2)) have movable joints:

Folding of the body elements (1, 3, 4, 5, 6) is carried out in such a way that the fixtures (8, 9, 10, 12) attached to them are not damaged by the body elements and at the same time do not interfere with the body elements during and after folding ... After folding the body elements connected by movable joints, side walls are applied to them from one of the sides.

An exemplary folding process can be followed in FIG. 5, which shows the beginning of the process, while it is proposed that the front wall (1) folds into the interior of the dust chamber, pressing against the lower part (3), and the lower part (3) folds outward of the dust chamber in the direction of the rear wall (4). The transparent wall (6) folds outward of the chamber in the direction of the transparent top (5), which folds into the dust chamber, pressing against the rear wall (4) and the elements fixed to it.

FIG. 6 you can see the continuation of the folding process of the anti-dust chamber. And in FIG. 7 and FIG. 8 shows views of the dust chamber in a folded state. It can be seen here that the side walls (2), which were not previously involved in folding, are simply applied to other elements. The front wall (1) can be either completely pressed against the lower part (3), or move away from it at a certain distance, which depends on the material of manufacture of the sleeves (7) and its flexibility.

To describe the operation of the invention, it is proposed to consider the fully functional model indicated in the images, but in some modifications some structural elements may be missing, which will be described in more detail later in the section "Features of the invention".

In general, regardless of the type, the invention works as follows:

Previously, the external wire (13), if any, is connected to a power source, which may be an ordinary household outlet.

To carry out work related to the appearance of dust, sawdust, shavings or other processing elements, the workpiece is placed inside the dust chamber through a gap formed by a raised transparent top and a transparent wall (5, 6) together or only by a raised transparent wall (6) or a transparent top (five). In this case, the tool, table-top machine or other device can be fixed directly on the fastening pad (15) or in the holder (14), if any, and the tool can also be unsecured and held in the hands of a person.

If necessary, the tool, machine or device is connected to the socket inside the dust chamber (10).

Before starting work, the light source (12) (if available) can be manually turned on for better illumination of the work area, and the fan (9) can also be manually turned on. In addition, the light source (12) and the fan (9) can be turned on during the work or during the work period, depending on the amount of dust and the convenience of the available lighting.

Immediately before starting work, the transparent elements (5, 6) are omitted. Next, a person pushes and places his hands in the holes (in the front wall (1)) with armbands (7), which mainly fit the hand, not letting in dust, and performs work inside the dust chamber for processing any part with the help of any tool or desktop machine.

The rear wall (4) may have holes for air exchange during operation, but the holes are covered with filters (8) to prevent dust, sawdust, shavings from escaping from the dust chamber.

In the event that a fan (9) is present in the anti-dust chamber, then it mainly works to remove air from the anti-dust chamber, since in this case it is able to collect dust from the air inside the chamber and deposit it on the filter (8), together with which it is located.

It is not recommended to use the fan (9) to enter (suck) air into the anti-dust chamber, since the air flow from the fan will only intensify dust dispersal and reduce the quality of work.

Therefore, the air exchange in the modification, which is shown in the images, when the fan is running, is carried out as follows:

Air is introduced through filters (8) located separately (filters in this case are designed to cover openings in the rear wall (4)). Further, fresh air mixes with air in the dust chamber and picks up the existing dust particles. Dusty air is sucked in by the fan (9) and discharged outside the dust chamber, while the existing dust particles settle on the filter (8), which is located together with the fan (9).

In some cases, the anti-dust chamber can have an outlet pipe (16), which is designed to remove air from the anti-dust chamber in a given direction (the direction of the pipe and its location is set before the start of work by a person). These cases may be situations when parts with an unpleasant or toxic odor are processed in the dust chamber, which manifests itself immediately or during processing. In this case, the outlet pipe can be placed in window or door openings or connected to the ventilation available in the room.

Features of the invention and possible modifications:

1. Automatic fan start-up. In some cases, the dust chamber can be equipped with air purity control sensors, which will automatically turn on the fan (9) when dust appears in the air inside the dust chamber.

2. Varieties of filters. Filters (8) can be placed separately or together with a fan (9). Filters (8) designed to introduce air into the dust chamber can be made of the simplest materials, since the only requirement imposed on them is not to release dust and other elements from the dust chamber. The filter designed to remove air from the dust chamber and placed together with the fan (9) should be more complicated, since an additional requirement is imposed on it - to collect the generated dust and other elements. It can have a denser structure for better dust retention and / or it can be made in the form of a cyclone type filter (like a cyclone filter in a vacuum cleaner) with dust and other elements retention on the side walls, or the filter can be supplemented with a dust collection system ( dust compartment or bag).

3. Anti-odor filter. When carrying out work related to the appearance of toxic and unpleasant odors, it is possible to use a filter (8) together with the fan (9), which neutralizes the odor. Such a filter can have a natural (eg charcoal) or synthetic base and can be supplemented with a fragrance or fragrance (eg impregnation). The odor filter can be used with or without a discharge pipe (16).

4. United transparent elements. The transparent top and the transparent wall (5, 6) can be made in the form of one single piece of glass, organic glass, plastic. In this case, the corner of the connection of transparent elements can be rounded.

5. Placement of light sources. The light source (12) is not an obligatory structural element, but when using it, the number of light sources (12) and their location is unlimited. They can be located both at the front wall (1) and at the back (4) and unlimited in height and shape. But there are two requirements for the location of the light source:

1) the light source should not block the view when working inside the dust chamber;

2) the light emanating from the light source should not blind the person working in the dustproof chamber.

6. Desktop machines and special equipment. The anti-dust chamber almost does not limit the type and set of tools that can be used inside it, it is important to observe only ease of use and the ability to ensure safety when working with the tool. So inside the anti-dust chamber, desktop machines can be placed (for example, they can be fixed on a mounting plate (15)), burners, chemicals (in a container), specialized jewelry, engraving and other tools.

7. Availability of additional fastening. The tool holder (14), although not an obligatory structural element, is capable of increasing the ease of use of the dust chamber. In the images, the holder (14) is shown schematically and can have any other form, intended for a specific type of tool. And also, together with one anti-dust chamber, several holders (14) can be used, each of which is compatible with one or another tool.

8. Method of folding the dust chamber. The folding of the Type II anti-dust chamber has been described using the example of the presented images. But it should be borne in mind that other folding methods are possible, depending on the size of the dust chamber, the availability of equipment, the method of fastening the structure, etc.

9. Fastening the sidewalls. The sides (2) can be attached to the rest of the structure using bolts, screws, screws, latches, pins, blockers, dowels or magnets. For example, in FIG. 9 shows a possible method of fastening the sidewalls (2) using a metal insert (17) inserted into the structure (in the picture, the rear wall (4)), which can be inserted using an interference fit, screwed in, glued or otherwise locked inside. And a magnetic pin (18) is inserted into the hole in the sidewall (2), which is magnetized in such a way as to be held inside the metal insert (17). Further, the sidewall (2) together with the magnetic pin (18) is brought to the counterpart with the inserted metal insert (17) and is attracted to it due to the alignment of the pin (18) and the insert (17).

10. Tightness. Although there is no need for complete tightness to work in a dust chamber, the presence of large gaps between body parts (1, 2, 3, 4, 5, 6) is unacceptable. In some cases, a seal can be used to reduce the gaps (for example, between the sidewall (2) and the transparent elements (6, 5)).

11. Material of the sleeve. The sleeve (7) is designed to prevent dust from escaping from the dust chamber through the hand openings. Therefore, it must ensure tight contact with the human hands. The material for its manufacture can be rubber, latex, silicone, dense fabric. In the case of the manufacture of a sleeve (7) from fabric, an elastic element, for example, an elastic band, is sewn or inserted into its inner diameter.

12. Used loops. The hinges in the structure can be used both for attaching the transparent top (5) to the rear wall (4) and in other places, which is especially important for a type II anti-dust chamber (for example, between the front wall (1) and the sidewall (2) or the bottom part (3)). It is permissible to use hinges of any design, including those screwed to the housing elements, but it should be borne in mind that some types of hinges increase the gaps between the housing elements and their presence can violate the aesthetic appearance of the dust chamber. Therefore, the most optimal option looks like in which the housing elements are inserted into each other and connected by an axis that ensures the movement of one part of the housing relative to the other. An example of such a loop is shown in FIG. 10 using the example of joining part of the rear wall (4) and part of the transparent top (5). As you can see, they have edges made in the form of protrusions, which allow the parts to be inserted into one another. Moreover, the protrusions have holes inside them, into which the axis (19) is inserted, which ensures the rotation of one part relative to the other.

13. The use of springs or stops on the opening part of the structure. It is assumed that the transparent elements (5, 6) will be carried out lifting together or separately in order to ensure the placement of workpieces and tools / equipment inside the dust chamber. Since it is inconvenient to hold the transparent elements (5, 6) in the raised state when placing the tool, it is assumed that the dust chamber can be equipped with springs, gas springs or stops to hold the transparent elements (5, 6) in the raised position. In this case, the stop can be applied manually, and the spring or gas spring can not only hold the transparent element or elements, but also lift them from the lower position. If one of the types of springs is used, then it is permissible to use latches, locks or blockers that prevent the lifting of the transparent element.

14. Thermal strength. It is assumed that parts can be processed inside the dust chamber using burners and other heating elements. In this case, the anti-dust chamber and its body (its elements) can be made of heat-resistant and non-combustible materials (refractory metals, ceramics, some types of minerals, etc.) or the material for the manufacture of the anti-dust chamber can be treated with impregnation (fire protection) to increase thermal strength ...

15. Impact resistance. When working with a tool, situations sometimes arise when a part or part of it is pulled out of the machining zone at high speed. Or, for example, the tool tip breaks. All these situations can lead to the fact that parts of the tool, tool bit or part and its parts can hit the elements of the anti-dust chamber at high speed. Therefore, the elements of the anti-dust chamber are made of shock-resistant materials (mainly the body) or from shock-absorbing materials (mainly the internal parts of the anti-dust chamber).

16. Bending of the back wall. In images such as FIG. 1, fig. 2, fig. 3, fig. 7, figs. 9, it is noticeable that the rear wall (4) is depicted with a slight bend (with an angle) in the upper part, due to which part of the rear wall runs perpendicular to the main space of the rear wall (4) and parallel to the lower part of the housing (3) in the unfolded state of the anti-dust chamber. The reason for this design is that the largest number of additional elements is supposed to be placed on the rear wall (4), such as a socket (10), a light source (12), a filter (8), a fan (9). In this case, the bend (angle) of the rear wall serves to improve the fastening of structural elements, for example, the light source (10), and to protect additional elements when folding the type II anti-dust chamber.

17. Application of an external wire. The external wire (13) is designed to connect the power supply to the electrical equipment of the dust chamber and to the socket (10). But in the absence of electrical equipment inside the dust chamber, the external wire (13) may be absent due to the widespread use of cordless tools. Also, instead of an external wire (13), the dust chamber may contain a small hole for connecting a wire from the tool used directly to a household outlet (meaning a socket in the room).

18. Material of the outlet pipe. It is assumed that the outlet pipe (16) should be made of flexible materials to ensure the best possible positioning in the room. Such materials can be corrugated metal, corrugated plastic, rubber. It is also possible to use solid materials (plastic, metal, wood) with the condition of the presence of movable joints in some places of the outlet pipe (16), which will ensure the rotation of its parts.

The declared result is achieved by using a closed chamber with transparent elements to control the work area, openings for hands and allowing to place inside a tool, table-top machines and other equipment.
