Description

The invention relates to devices that are intended for the care of surfaces, mainly leather and plastic products, and can be used in the construction of devices intended for the care of shoes, leather products, suede products, surfaces of household items and the like, namely devices containing a highly elastic porous synthetic sponge in a hard case, which, depending on the purpose of the device, may be dry or impregnated with a substance intended for application surface coating of shoes or leather products, furniture and the like, for example, with a substance for cleaning and / or dyeing and / or glossing and / or prophylactic treatment of the surface of shoes, leather products, furniture and the like.

A device is known in the form of a brush for cleaning leather, which contains a sponge element made of a porous synthetic material, mainly polyurethane polyester, which has sufficiently large pores. The sponge element has a handle that serves as a cover for the tool box in which the sponge element is stored in the closed position. Due to the height of the box, the sponge element is stored in it in a free (not compressed) state (see application EP 468912 A1, publ. 01.29.1992, IPC: A46D 1/00, F47L 23/12).

Also known devices for the care of shoes and leather products, which are similar to the above analogue and contain sponges in a hard case and are supplied by various manufacturers in a wide assortment to the market.

So are known devices for the care of shoes and leather products (sponges of the AKURA trademark), which are manufactured and marketed by Interkord LLC, Kiev (see http://zakaz.ua/uk/products/?q=sponge % 20shoes). Such devices have a plastic case that contains a body and a lid, to the inner surface of which is attached a highly elastic porous synthetic sponge impregnated with a substance intended for application to the surface of a shoe or leather product. The cases of the marked products are made of elongated shape in horizontal section for ease of use, in particular in the form of an elongated rectangle with rounded corners, an arched rounded shape and in a shape that resembles the shape of the sole of the iron. Accordingly, the sponge supplied in these cases also has a shape similar to the shape of the case in which it is stored. The case cover serves as a handle to hold the sponge.

The case cover is held on the case body freely or due to friction, so the case is very easy to open. Also, to prevent the lid from falling off the case of the elastic plastic case when it is turned over or dropped on the contact vertical surfaces of the cover and the case body, which is made of plastic, sometimes small ribbed peripheral protrusions with inclined surfaces are performed. When the elastic case body is closed by a cover, elastic deformation of the cover and the case body occurs and the ribbed protrusions come in and engage each other and hold the cover on the case body. Since the peripheral protrusions are small, several tenths of a millimeter, considerable effort is not required to open the case. The cover is quite easy to remove from the case.

The height of the case of the described known devices depends on the thickness of the sponge, since the sponge, when located in a closed case, is in a free (uncompressed state). Since the height of the sponge is usually chosen with a height of about 3.5-4 cm, then, accordingly, the height of the case for the sponge is even larger. Due to their size, such surface care products, such as shoes, need a significant amount of carry-on baggage, so they are inconvenient to take with you in a briefcase, diplomat, small suitcase and the like and use when necessary at any time throughout the day. Moreover, such sponges are completely inconvenient so that they can be carried with you in your pocket. The amount of plastic that is necessary for its manufacture depends on the size of the plastic case. Therefore, to reduce the cost of raw materials for the manufacture of the case and, accordingly, reduce the cost of the device, it is advisable to reduce its dimensions without reducing the dimensions of the sponge made of highly elastic porous synthetic material.

A shoe and smooth skin care device is also known which comprises a sponge made of highly elastic porous synthetic material and attached to the inside of the lid of a round plastic case (see <http://www.hotelstyle.by/catalog-gubka_dlya_obuvi_s_propitkoy_v_shaybe.html >). The cover of the case is connected to the case of the case by means of a thread. The case has a height that is much less than the thickness of the sponge, due to which the sponge is kept in a closed case in a compressed state, which significantly reduces the dimensions of the case and allows you to take a shoe care device with you (see http://www.bythimiya.com/gubki .shtml). When the sponge is inside the case in a compressed state, from the side of the contact surfaces of the sponge made of highly elastic porous synthetic material, elastic reaction forces act on the lower surface of the case cover and the bottom of its body, aimed at opening the case and the case cover. The threaded connection elements, which are formed by the abutting parts of the round lid and the round case body, serve as locking elements of the device, which ensure reliable holding of the case in the closed position when the sponge is in a compressed state therein.

This device design is selected as the closest analogue of the claimed device.

The disadvantage of a round sponge, which is stored in a round case of the device, is the inconvenience of its use for cleaning the least accessible surfaces, for example, near the welts of shoes and the like. In addition, an increase in the working surface of the sponge can only be achieved by increasing its diameter, and therefore the diameter of the case in which it is stored. Since holding a large diameter lid with a sponge attached to it is rather inconvenient, round cases of devices for caring for the surfaces of products, in particular shoes or leather products, are made with a diameter of not more than 8 cm.

Most well-known devices for the care of shoes or leather products contain an elongated case, an approximate or similar form of a shoe brush, that is, non-circular. Such forms of cases and accordingly the shape of the sponges that are stored in them allow you to process or clean surface areas of products that are poorly accessible when using round sponges.

The objective of the invention is to provide a compact and easy-to-use device for surface care products that contains an elongated case, mainly close to the shape of a shoe brush, and which allows you to reliably hold and keep in it a compressed sponge made of highly elastic porous synthetic material that is attached to the bottom surface of the case cover.

This object is achieved using a device for surface care products, which includes a case containing a housing and a cover, as well as a sponge made of highly elastic porous synthetic material, which is attached to the bottom surface of the cover, while the case has a height that is much less than the thickness of the sponge and contains locking elements for holding it in a closed position with a sponge located in its cavity, which is in a compressed state between the bottom of the case body and its cover, in which According to the invention, the locking elements are formed by latches, which are connected by elastic legs to the bottom of the case body and are located near its opposite sides, and the corresponding supporting sections of the case cover, which are made from the side of its upper surface.

This embodiment of the proposed device allows the manufacture of cases of any longitudinal shape with a case height that is much less than the thickness of the sponge in its free (uncompressed) state, using structurally simple locking elements that securely hold the case in a closed position with a compressed sponge inside. This makes it possible to produce compact devices for surface care containing sufficiently compact cases in which the sponge is stored, with the shape of the lid convenient for holding in the hand, to the lower surface of which a sponge is attached, which has a larger working surface area than the sponge that is stored in a round case, and more effective when using a form for the care of poorly accessible surface areas of products.

Thus, the claimed device combines the advantages of a device that has an elongated case, comprising a cover that is convenient for holding a sponge attached to it and which has an elongated shape and is capable of processing poorly accessible surfaces of products, and a device containing a small round case , in which the cover of the case is connected to its body by means of a thread, and the round sponge is stored inside the case in a compressed state between the lower surface of the cover of the case and the bottom of the case.

The applicant is not aware of devices that contain a combination of essential features of the proposed device. This allows us to conclude that the claimed invention meets the condition of "novelty."

The use in the proposed device of the above locking elements that hold the case of the device in a closed position, which is acted upon by the reaction force from the side of the compressed lip to open it, together with its other essential features mentioned above, provides a solution to the problem of the invention.

Since technical solutions are unknown from the current level of technology that contain the distinctive features of the proposed device and which allow one to obtain the technical result of the proposed invention, this allows us to conclude that the claimed invention meets the condition of "inventive step".

The elastic legs can be made of bent shape, which contain horizontal and vertical sections, while the horizontal sections of the legs are connected to the bottom of the case body, and their vertical sections are connected with latches.

Thanks to this form of elastic legs, the case of the device is easier to open, since during the removal of the latches from the supporting sections on the cover, they deviate simultaneously to the side and up.

In the lid of the case, from the side of its lower side, in sections opposite the supporting sections for latches, guide inclined sections for latches are made.

The presence of these guide inclined surfaces provides easy closing of the case of the device.

The latches are in the form of narrow strips that are parallel to each other.

This embodiment of the latches simplifies the opening of the case by moving them with the fingers in two opposite directions.

When the case is closed, the elastic legs are closed by the outer walls of the case cover, and in the case cover there are windows for accommodating latches in the case when the case is closed, these windows have a width that allows the latches to be forced to move within these windows, which is sufficient to insert the latches onto supporting sections made in the cover of the case when closing the case and to release them from engagement with these supporting sections when opening the case.

Such a structural embodiment of the device ensures that the latches are held in the closed position of the case inside the latter, which prevents the latches or their legs from catching on other objects and accidentally opening the case, and also limits the amount of movement of the latches within the windows made in the case cover, which prevents significant elastic deformation of the latch legs when closing and opening the case, and consequently the accidental breakage of the latches or their legs.

In the closed position of the case, the latches partially protrude above the upper surface of the case cover.

This allows you to easily release the latches from their engagement with the cover of the case by releasing the latches from their supporting sections in the cover using the thumbs, acting on the protruding parts of the latches.

The case and the cover of the case have additional internal walls that are made at intervals to the side walls external relative to them and which, when the case is closed, form a closed chamber separated from the external side walls to hold the sponge in it between the bottom surface of the cover and the bottom surface of the case .

This embodiment of the device increases the shelf life of the sponge, which is impregnated with the substance and stored in a closed chamber of small volume, separated from the outer walls, thereby preventing its premature drying. In addition, the presence of additional internal walls increases the rigidity of the housing and the cover of the case, since the additional walls act as stiffeners. This is important for the claimed device, given that in the closed position of the case from the side of the compressed sponge, reaction forces act on the cover and bottom of the case, since with a small thickness of the walls of the case and cover of the case, their necessary rigidity is achieved, as well as the rigidity of the case as a whole.

Additional internal walls of the cover and case body are connected to the adjacent walls of the cover and case body, respectively, using jumpers.

The presence of jumpers additionally increases the rigidity of the case and the cover of the case.

The sponge can be made of flexible polyurethane foam. Such a sponge is capable of absorbing liquid, therefore, depending on the purpose of the device, this sponge may be impregnated with a substance that is necessary for applying to the surface of the products that are being looked after.

The sponge is made of reticulated polyurethane foam.

It is advisable to use such a sponge to care for nubuck.

Figure 1 and figure 2 shows in the closed position the inventive device for caring for the surfaces of the products. The device includes a hard case made of plastic, which contains the housing 1 of the case and the cover 2 of the case. A sponge 3 (see FIG. 1 and FIG. 7) made of a highly elastic porous synthetic material is glued to the bottom surface of the lid 2. The cover 2 of the case serves as a handle for holding the sponge 3 attached to it.

Sponge 3 can be made of flexible polyurethane foam (foam) or other highly elastic porous synthetic material that absorbs liquids well and is impregnated with a substance that is intended to be applied to the surface of the care products. In particular, it can be a substance for cleaning and / or coloring and / or prophylactic treatment of shoes or leather products, furniture polish and the like.

Sponge 3 can also be made of reticulated polyurethane foam to care for nubuck products.

The sponge 3 shown in FIG. 3 and FIG. 7 is in a free (uncompressed) state. As can be seen from the figures of the drawings, the height of the case of the device shown in Fig. 1 is much less than the height of the jaw 3 when the latter is in a free (uncompressed) state (see Fig. 3 and Fig. 8).

Sponge 3 as well as the case of the device are elongated. In particular, the figures of the drawings depict a shape close to the shape of an elongated parallelepiped. However, it is also possible to carry out a case and a sponge of a different shape. The housing 1 of the case (see Fig. 4, Fig. 6 and Fig. 9) has external walls 4, 5, 6, 7, inner opposite walls 8 and 9, which are perpendicular to and are connected by their edges to the outer longitudinal walls 5 and 7. The housing 1 also contains additional internal walls 10, 11, 12, 13, which are interconnected to form a closed loop. Additional internal walls 10, 11, 12, 13 of the housing 1 are made with gaps to the outer walls 4, 5, 8, 9 of the housing, respectively, and connected to them to increase the rigidity of the housing by means of jumpers 14, the height of which is less than the height of the walls that they connect (see Fig.6 and Fig.9).

As can be seen in figure 4, the drawings, the height of the outer walls 4 and 6 of the casing is made smaller than the height of its longitudinal walls 5 and 7, so that the inner walls 8 and 9 of the casing have external open sections that do not overlap with the outer walls 4 and 6 of the casing.

The cover 2 of the case (see Fig. 3, Fig. 5, Fig. 8 and Fig. 11) has external walls 15, 16, 17, 18, inner opposite walls 19 and 20, which are perpendicular to and are connected by their edges to the external longitudinal walls 16 and 18. Cover 2 also contains additional internal walls 21, 22, 23, 24, which are interconnected to form a closed loop. Additional inner walls 21, 22, 23, 24 of the cover 2 are made with gaps to the outer walls 15, 16, 17, 18 of the cover, respectively, and connected to them to increase the rigidity of the cover using jumpers 25, the height of which is less than the height of the walls that they connect (see Fig.5 and Fig.8).

The dimensions of the walls of the case 1 of the case and its cover 2 are made in such a way that when the device case is closed, the external walls 15, 16, 17, 18, the covers 2 of the case cover the outer walls 4, 5, 6, 7 of the case 1 of the case, and the walls 19 and 20 covers cover the outside walls 8 and 9 of the housing, and vice versa, additional internal walls 10, 11, 12, 13 of the housing cover with guaranteed overlap 26 additional internal walls 21, 22, 23, 24 of the cover (see Fig.7). Moreover, due to the dimensions of the walls of the housing and the lid of the case in the closed position of the case, the aforementioned enclosing walls and the walls enclosed by them are sufficiently close to one another and form a closed chamber 27 in which the sponge 3 is compressed (see Fig. 7), attached to the lower surface of the cover 2, which is covered by the inner additional walls 21, 22, 23, 24 of the cover. The chamber 27 (see Fig. 7) is sealed with two contours of the walls of the lid and the housing, which form a labyrinth seal.

The device also contains locking elements for holding it in a closed position, which are formed by two latches 28 and 29 made on the housing 2, which are located in the closed position of the housing 1 near its opposite walls 17 and 18, each of which has the shape of a narrow strip (see Fig. .1, FIG. 4, FIG. 6 and FIG. 9). In the closed position of the case, the latches are inside the case and only partially protrude above the upper surface of its cover 2.

The latch 28 is connected to the bottom of the case body by two curved elastic legs, each of which contains horizontal sections 30 (see FIG. 6), which are connected to the bottom of the housing 1 and connected to the latter vertical sections 31 (see FIG. 4 and FIG. .9) on which the latch 28 is held.

Similarly, the latch 29, which is made on the opposite side of the housing 1, is connected to the bottom of the case body by two curved elastic legs, each of which contains horizontal sections 32 (see FIG. 6) that are connected to the bottom of the housing 2 and connected to the latter vertical sections 33 (see figure 4 and figure 9), which holds the latch 29.

In the lid 2, on the side of its upper horizontal surface 34, on the two opposite edges are made support sections 35 for the latches 28 and 29, having a surface parallel to the upper surface 34 of the lid 2, located below the level of the surface 34 and located within the windows 36 and 37, respectively, which are made in the cover 2 (see figure 10). In the lid 2 from the side of its lower side, on sections opposite to the portions of the upper surface of the lid, on which the supporting sections 35 are placed, the guide inclined sections 38 for the latches are made.

Windows 36 and 37 serve to accommodate the latches in the closed position of the case and have a width that allows the latches to deviate within these windows, which is sufficient to install the latches 28 and 29 on the corresponding support sections 35 made in the lid 2, when closing the case and to release the latches from their engagement with these protrusions when opening the case.

When the case of the claimed device is closed, the sponge 3 is in a compressed state inside its closed chamber 27 (see Fig. 7). In this case, the compressed elastic sponge 3 exerts an elastic reaction action on the lower surface of the cover 2 and the bottom surface of the housing 1 of the case, which is aimed at opening the case. The opening of the case is counteracted by locking devices, which are formed by latches 28 and 29, which in the closed position of the case are engaged and reliably supported by their lower surfaces on the horizontal surfaces of the supporting sections 35 and hold the case in the closed position. In this case, tensile forces act on the elastic legs of the latches, which are caused by the reaction elastic forces of the compressed jaw 3.

The case of the proposed device is opened by releasing the latches 28 and 29 from contact with the surfaces of the supporting sections 35. This is achieved by horizontal movement of the latches 28 and 29 with the thumbs of the hands from the surface of the supporting sections 35 within the windows 36 and 37, when the index fingers and thumbs of two hands hold the case body. After releasing the latches, the case of the device quickly opens as a result of the action on its cover 2 and the housing 1 of the elastic reaction forces from the side of the compressed jaw 3.

After opening the case, the sponge 3 is in a free (uncompressed) state and takes the initial shape, which is shown in Fig.3 and Fig.8 of the drawings.

The applicants tested a prototype of the proposed device, which had a shape close to the shape of a parallelepiped, while the cover and case were made of polystyrene by plastic injection molding, which ensured high accuracy of their geometric dimensions and high tightness of the closed chamber 27 for accommodating the sponge. The tests of the prototype device confirmed the achievement of the above technical results of the invention. The manufactured prototype device had a case height of only 12 mm and, thanks to the proposed locking elements, held a sponge inside the chamber 27 of the case in a compressed position, which has a height of 40 mm in a free (uncompressed) state. At the same time, closing and opening the case of the device was quite easy and quick without undue effort.
