Tactile pointer

Technical field

The utility model relates to tactile pointers for the visually impaired.

State of the art

The tactile pointer is a means of displaying information, which is a strip of various materials of a certain color and corrugation pattern, which allows the visually impaired to recognize the types of road or floor coverings by touching with feet, walking sticks or using residual vision (see GOST 52875-2007 “Tactile pointers ground-based for the visually impaired ”, appeal date 09.16.2015). Depending on the information transmitted to the visually impaired, tactile pointers are made of two types: directional pointers and warning pointers. The directional signs provide the opportunity for the visually impaired to move in the right direction on their own, the warning signs provide the opportunity for the visually impaired to navigate in space and avoid dangers that could be harmful to health. The tactile pointer differs in structure and color from the pedestrian surface, which ensures its recognition in relation to the pedestrian surface by the visually impaired by touching the feet with a foot or cane and (or) visually. Pedestrian surface means a pedestrian zone adjacent to a tactile pointer.

The closest technical solution (prototype) are ceramic and paving concrete tiles with guides or warning protrusions on the supporting surface for orientation of the visually impaired (GOST R 52875-2007 "Tactile tactical signs for the visually impaired" Technical requirements). The device comprises a continuous web, abutment surface, lower part and protrusions. The combination of the supporting surface and the protrusions on it form an information layer that forms the set of information necessary for the movement and orientation of the visually impaired.

In the process of people moving on a pedestrian surface, dirt remains on the soles of shoes. When you step on the tactile pointer, dirt peels off the shoe and adheres to the supporting surface of the tactile pointer. Subsequently, dirt accumulates on the supporting surface.

A disadvantage of the known technical solution is the impossibility, problematic or erroneous recognition of a set of information by the visually impaired in the event of accumulation of dirt on the supporting surface.

The technical result of the proposed utility model is the ability, reliability and accuracy of recognition of a set of information in the event of accumulation of dirt on the supporting surface.

The specified technical result is achieved due to the fact that in the tactile pointer containing the canvas with the lower part and the supporting surface, and the information layer in the form of protrusions placed on the supporting surface, the mesh is made of dirt-retaining cells in the form of through holes starting from the bottom and ending on a supporting surface; in the particular case, the protrusions are placed in the middle zone of the canvas; in the particular case, the protrusions are placed between the through holes; in the particular case, the protrusions are made integral with the web.

Brief Description of the Drawings

The utility model is illustrated by the figures (Figs. 1-2), where in Figs. 1 shows a top view of a tactile pointer, FIG. 2 shows a side view of a tactile pointer.

Utility Model Disclosure

The figures indicated: pedestrian surface 1, protrusion 2, front part 3, tactile part 4, rear part 5, dirt-retaining cell 6, side wall 7, through hole 8, web 9, abutment surface 10, information layer 11, lower part 12.

The main element of the tactile pointer is the canvas 9. The canvas 9 is a product with a cellular structure, having a shape similar to a rectangular parallelepiped. The tactile pointer is equipped with two equal faces that are opposite to each other and have the largest area relative to other faces. One of them is facing the user (supporting surface 10), and the other is facing the pedestrian surface 1 (lower part 12). The edges of the sides of the parallelepiped correspond to the thickness of the web 9. The geometric dimensions of the sides of the supporting surface 10 and the lower part 12 are selected so that they are much larger than the thickness of the web 9.

The canvas 9 can be made of polymer, rubber materials or various metals. Through holes 8 are made in the material of the web 9 with the formation of a cellular structure. The cellular structure may occupy the web 9 in whole or in part. The cellular structure can be made either in the form of a set of separate dirt-retaining cells 6, or dirt-retaining cells 6 formed in a single fragment.

The dirt-retaining cell 6 is a discrete element of a certain shape, the combination of which forms a cellular structure. The shape and dimensions of the dirt-retaining cells 6 are selected depending on the necessary protection against dirt. For example, the larger the fraction of dirt, the larger the size of the dirt-retaining cells 6. The dirt-retaining cell 6 is structurally composed of side walls 7 and through holes 8 between them. The surface of the side walls 7, depending on the shape of the dirt-retaining cell 6, may be flat or curved. Through the surfaces of the side walls 7 from the supporting surface 10, through holes 8 pass to the lower part 12. The dirt-retaining cells 6 are designed to protect the premises from dirt penetrating into the premises on the soles of the shoes due to the separation of dirt by the upper ribs of the side walls 7 and the collection of dirt in the through holes 8 The height of the dirt-retaining cell 6 is equal to the thickness of the web 9 and is selected with the possibility of collecting the necessary amount of dirt.

Cloth 9 can be performed in two versions: monolithic and modular. In a monolithic design, the web 9 is made with a non-separable product. In a modular design, the web 9 consists of separate sections that are reliably connected to each other like puzzles. In all versions, on the supporting surface 10 of the canvas 9, three consecutive rectangular zones are allocated: the front part 3, the tactile part 4, the rear part 5. The tactile part 4 is located between the front part 3 and the rear part 5. On the tactile part 4 there are protrusions 2, the location of which forms a specific tactile signal.

The protrusions 2 are convex elements of a certain shape, designed to inform the visually impaired of the ways of movement by touching the feet or walking stick. The protrusions 2 are made of wear-resistant materials, such as metal, granite, artificial rubber, polycarbonate. In the particular case, the protrusions 2 and the web 9 can be made of one material. The shape and relative position of the protrusions 2 are performed depending on the type of tactile pointer. In particular, the protrusions 2 of the guiding tactile pointer may be in the form of truncated cones or truncated square pyramids. The protrusions 2 of the warning tactile pointer may be in the form of straight edges with flat vertices or straight edges with a sinusoidal profile. At the same time, truncated pyramids, truncated cones and straight ribs have beveled or rounded edges to reduce the likelihood of injuries. The protrusions 2 can be located parallel or diagonally at an angle of 45 ° to the direction of movement. The protrusions 2 are securely fixed to the supporting surface 10 to prevent shear when in contact with shoes or a cane.

The fixing of the protrusions 2 on the supporting surface 10 can be performed in two ways. In the first method, the protrusions 2 can be cast together in one mass with the web 9 directly on its supporting surface 10. In the second method, the protrusions 2 can be manufactured separately from the web 9. Then, the protrusions 2 are fixed to the supporting surface 9 either with glue or with a snap item. The latching element can be located either on the protrusion 2, or on the supporting surface 10. The protrusions 2 together with the supporting surface 10 form an information layer 11. The information layer 11 (its configuration) forms the message necessary to inform the visually impaired when moving for their orientation in space.

Utility Model Implementation

The device is implemented as follows. In the particular case, the tactile pointer is made by pressing. The material of the tactile pointer is loaded into the mold, where under the action of pressure the web 9 is formed with through holes 8 and protrusions 2 on the supporting surface 10. As a result of curing, the predetermined configuration of the tactile pointer is fixed.

Tactile pointers are installed in places that can be visited by the visually impaired, namely: sidewalks, underpasses, floors inside public buildings and structures, stairs and ramps. Tactile pointers are placed so that its lower part 12 is facing the pedestrian surface 1, and the supporting surface 10 is towards the user. If the tactile pointer is located in front of the entrance to the room, then its front part 3 should be facing towards the entrance to the room, and the rear part 5 should be facing the incoming person. In the particular case, the rear part 5 can perform the function of the first stage of dirt protection, as a result of which the rear 5 part can have large dirt-retaining cells 6. In this case, the front part 3, respectively, will perform the function of the second stage of dirt protection and have dirt-containing cells 6 of a smaller size. Tactile pointers are secured in any known manner, in particular by gluing or using fasteners.

A visually impaired person steps on the rear part 5 of the supporting surface 10. The dirt-retaining cells 6 remove large fractions of the dirt entering the soles of the shoes as follows. The upper ribs of the side walls 7 divide large fractions of dirt into small parts, which settle and accumulate in the through holes 8. Next, the visually impaired leg or cane touches the tactile part 4, on which the information layer 11 is placed. Information layer 11 by tactile contact with the leg or the visually impaired person’s cane gives him a set of information about the further path of movement. Next, a visually impaired person steps on the front part 3 of the supporting surface 10, in which the dirt-retaining cells 6 stop the medium particles of dirt.

Thus, the implementation of the tactile pointer in the manner described above provides the possibility, reliability and accuracy of recognition of the information set in the case of accumulation of dirt on the supporting surface 10. This is due to the implementation in the canvas 9 of the cellular structure, the dirt-holding cells 6 which prevent the impossibility, problematic or erroneous recognition of the information set visually impaired in the event of accumulation of dirt on the supporting surface 10 by separating and collecting large fractions of dirt in front of the tactile part 4.
