Description

Information Presentation Device

Technical field

The utility model relates to devices for presenting information, namely, projection devices, in particular, projection devices intended for carrying, and can be used to dynamically present information to third parties, for example, during a presentation, lecture, or video and animated films.

BACKGROUND OF THE INVENTION Designs of portable projection devices equipped with a carrying device in the form of a handle or a flexible element, for example, a belt, are known.

For example, a portable projector is known, consisting of several parts articulated between each other, containing an autonomous power source, as well as a flexible element - a belt for carrying the projector. During operation, the device is disassembled, one of the parts of the projector forms a support element and is mounted on a certain surface to start displaying information (see German patent for invention JVb DE10021162, IPC H 04N 5/74, G 03B 21/30, H 04N 1/23 , published on November 15, 2001). However, displaying information using a known device is difficult in the absence of a flat surface or its placement away from a vertical surface serving as a screen. Thus, the mobility of the device is reduced, which negatively affects the consumer properties of the projector.

Also known is a projection device for creating visual images on a vertical surface, equipped with a handle for supporting it, placed on the projector case (see U.S. Patent N ° US5526076, IPC G 09F 19/16, G 09F 19/12, G 03B 21/28, published on June 11, 1996).

A disadvantage of the known device is also its low consumer properties, which is associated with the need to use the hands of the operator during operation of the projector, which makes it difficult, in particular, to display information for a long time due to the significant load on a person’s hands. However, there are known designs devoid of the above disadvantages associated with the workload of the operator’s hands or low mobility of the device.

So, for example, a projector is known that receives information about the presented image via a radio channel and is made in the form of an earphone worn on a person’s head, while the light source in the projector is mounted in the body of the earphone, and the information source, for example, a radio station, is attached to the belt person (see the application for a Japanese patent for the invention of JVb JP2000152202, IPC G 02B 27/02, G 09F 9/00, H 04N 5/225, H 04N 5/40, H 04N 5/44, H 04N 5/64 , H 04N 7/14, H 04N 7/18, H 04Q 7/38, H 04N 5/38, publ. 05/30/2000).

However, a disadvantage of the known device is also its low consumer properties. This is due to the long-term operation of the source of electromagnetic radiation (projector) located near the human brain, as well as the need for constant wearing on the head of a famous projector. This may entail, for example, increased operator fatigue, and, accordingly, a decrease in its working capacity. In addition, it is difficult to use the known projector in the open air due to the high degree of exposure to climatic factors, for example, precipitation, dust.

Known projector for displaying and projecting onto the surface of electronic information issued by at least one electronic device, the electronic device is a portable external device, and the projector is separate, made with the possibility of attaching to the user's clothing, and the electronic device is connected with said projector, which comprises at least one light emitting means for projecting the information to be displayed, as well as optical components onenty and electronic components necessary for the projection to be displayed information (see. the application for semi chenie RF patent 2002133232 Na, IPC G 06F 1/16, publ. 20.04.2004).

A disadvantage of the known device is its susceptibility to negative effects from various climatic factors, for example, precipitation, when it is used in open space, which may entail when it is used in an open space, which may result in a projector malfunction, and indicates its low consumer properties and unreliability.

A projector and a projection system mounted on the head are also known, the projector being equipped with a support element repeating the head contour and mounted on the head so that the screen is placed in front of the user's eyes (see Japanese Patent Application N ° JP2004252095, IPC G 02B 27 / 02, G 02B 27/18, G 03B 21/00, G 03B 21/30, H 04N 5/64, published 09.09.2004). A disadvantage of the known device is also its susceptibility to the negative effects of weather environmental factors, for example, dust, precipitation, as well as increased operator fatigue caused, for example, by the presence of a long time on the head of a foreign object, which is at the same time a source of electromagnetic radiation, which indicates low consumer properties of a famous projector. At the same time, only one person can observe the information.

Closest to the proposed technical solution is a known projection device equipped with a container for carrying it, thereby facilitating the carrying of the projector by reducing the physical force necessary to carry out the transfer, as well as simplifying the installation of a projection device for displaying information. The projection device is contained in a container attached to a long support rod with a handle by means of a rotating hinge. During operation, the container with the projector rotates relative to the support rod until it is placed in a horizontal position, while the container is supported from below by a support element consisting of several arms, bent to each other at the required angle and abutting against the support rod (see application for obtaining a Japanese patent for invention N ° JP2001275729, IPC A 45C 5/14, A 45C 7/00, A 45C 7/02, A 45C 11/00, H 04N 5/64, A 45C 5/00, publ. 09.10. 2001). However, during operation, unauthorized movement of the container with the projector is possible, for example, due to a change in the position of the support rod, after which the container on the movable hinge will fall down, will shift to an undefined angle, which will cause the image to shift zheniya. This complicates the use of the known device, which indicates its insufficient consumer properties. In addition, to shift or slightly move the image, it is necessary to turn the entire installation as a whole, which is also difficult due to its size and design, in particular, the integral connection of the casing and the support. At the same time, in the connection of the casing and the support, for example, by the hinge, the appearance of backlashes is possible, which will also negatively affect the use of the known device, since when turning it, namely turning the support by a certain angle, the projector, and, accordingly, the image will shift due to backlash to another angle, which will distort the image, or move it to an unsuitable surface for display.

Utility Model Disclosure

The objective of this utility model is to create a device for presenting information with a design having enhanced consumer properties, expressed in simplifying device management during operation.

The technical result achieved in solving the problem is to provide a rigid fastening of the device relative to the support, with the possibility of synchronously changing the orientation of the support and the projection apparatus and maintaining the isolation of the latter from the external environment, as well as minimizing the number of degrees of freedom of the elements of the device relative to each other.

This object is achieved in that in a device for presenting information comprising a projection apparatus and a device for carrying it, the projection apparatus is provided with a housing element, and the adaptation for carrying the projection apparatus comprises a housing covering at least two sides of the housing element , according to a utility model, a device for carrying a projection apparatus comprises at least one removable fastening element with the possibility of its installation on a vertically oriented one of its elements in contact with the rear side of the support, the device for carrying the projection apparatus in contact with the housing element.

The casing may be made of elastic material or hard material. The casing can be made in the form of a cover and cover the top and sides of the projection apparatus.

The removable fastening element can be made in contact with the casing and either contain a clothing element or be made in the form of a flexible belt.

In addition, the device for carrying the projection apparatus can additionally be equipped with a support mechanism in contact with the housing element of the projection apparatus, and attached to a removable mounting element. The presence in the device for carrying the projection apparatus of a removable fastening element relative to the support on which the device for carrying the projection apparatus can be placed allows it to be transported in a disassembled state from one place of operation to another as a whole without additional support, which simplifies the management of the device for presenting information during its operation. At the same time, the possibility of contact of the removable element with the back of a vertically oriented support, which may be played by the device operator to present information, allows the device to be rigidly fixed to the operator (or any other support), minimizing the number of degrees of freedom of the device elements relative to another, in this case, the projection apparatus relative to the carrying device. In this case, the device as a whole, rigidly fixed relative to the support, has a degree of freedom equal to 1. The degree of freedom is 1. This will allow you to synchronously change the orientation of the operator (or support) and the projection apparatus of the proposed device, which simplifies device control during operation, and also provides the ability to carry the device already in operation, without changing the weight of the installation, nor its dimensions and without the need for any additional manipulations for installation and dismantling, which increases consumer device properties and also simplifies its management. So, for example, if the installation operator acts as a support, then to rotate the projection apparatus and change the projection location of the image, it is enough, without additional help from the operator’s hands, only to turn the case, to correctly rotate the projection apparatus to the required angle in any direction. The presence of a casing covering at least two sides of the projection apparatus, for example, the upper and the front, allows you to save the protection of a fairly expensive projection apparatus from the negative effects of the external environment. The contact of the device for carrying the projection apparatus with one of its elements, for example, a casing or a removable element, with the housing element of the projection apparatus enhances its protection against any unauthorized movements in any direction.

The casing of the device for carrying the projection apparatus can be made of elastic material, for example, in the form of a cover, or of a rigid (solid non-deforming) material that ensures the constancy of the geometric (overall) dimensions of the casing. An embodiment of the casing of elastic material is preferable to further reduce the dimensions of the device as a whole, since in this case the dimensions of the device will actually be limited by the dimensions of the projection apparatus, the casing will fit tightly, and also to further reduce weight by reducing the weight of the casing. Such an implementation simplifies the use of the proposed device, at the same time, providing a synchronous change in the orientation of the support and projection apparatus and maintaining the isolation of the latter from the external environment. An embodiment of a casing made of solid non-deformable material, ensuring the constant geometric (overall) dimensions of the casing, is advisable when the device is operated in difficult climatic conditions, in which a hard rigid casing will provide more reliable isolation of the projection apparatus from the external environment, as well as unauthorized shocks during the movement of the operator. The removable mounting element can be made in contact with the casing, which will further increase the stiffness of the device as a whole and helps to ensure synchronous changes in the orientation of the support and projection apparatus while minimizing the number of degrees of freedom of the device. In this case, the removable fastening element can either contain a clothing element in contact with the back of the support (operator’s back), or be a flexible belt worn, for example, on the neck of the operator, and also in contact with its rear side, which provides a rigid fastening of the device relative to the support , however, does not require, unlike the prototype, one-piece binding the casing of the projection apparatus to the support, making it difficult to completely disassemble the device into structural elements.

The presence in the device for carrying the projection apparatus of the support mechanism in contact with its housing element and attached to the removable fastener also further increases the rigidity of the device relative to the support, providing a synchronous change in the orientation of the support and projection apparatus, which simplifies device control during operation.

Best embodiments of the utility model. A device for presenting information comprises a projection apparatus and a device for carrying it.

The projection apparatus is equipped with a housing element 1, and the device for carrying the projection apparatus includes a casing 2, covering at least two sides of the housing element 1 (Fig. 1, 2, 4, 6). In addition, the device for carrying the projection apparatus contains at least one removable fastening element 3 with the possibility of its installation on a vertically oriented support 4 and in contact with the rear side of the support 4 (for example, a person) (Fig. 1-6), while device for carrying the projection apparatus with one of its elements, either with a casing 2 (Fig. 1-6), or with a removable fastening element 3 (Fig. 2-6), is in contact with the housing element 1.

By a vertically oriented support in the present description of a utility model is meant such a support, the projection from which onto a vertically oriented coordinate axis exceeds that of a similar projection onto the horizontal coordinate axis.

The casing 2 is made of an elastic material and is, for example, a cover worn on the projection apparatus and covering the upper and side sides of its housing element 1 (Fig. 1). In this case, the removable fastener 3 can be made in the form of a flexible belt (Fig. 1) in contact with the casing 2.

The casing 2 may be a cloak or cape made of flexible, for example, woven material, and placed on top of the projection apparatus (Fig. 6).

At the same time, to solve the problem, it is sufficient to close at least two sides of the projection apparatus, for example, the upper and front sides (the back side is covered by a support 4), while the casing area in horizontal projection may exceed the area of the upper side of the projection apparatus that will maintain the isolation of the projection apparatus from the effects of the external environment.

The casing 2 can be made with fixed dimensional (geometric) dimensions of a rigid material, for example, plastic, aluminum (Fig. 2 and 4). In this case, the hard casing 2 is attached both to the housing element 1 of the projection apparatus and to the removable element 3, for example, its supporting mechanism.

The removable fastening element 3 in contact with the back of the support 4 may contain a clothing element (Figs. 2 and 3), for example, a vest made of elastic (flexible) material, for example, dense fabric or leather. At the same time, a support mechanism is attached to the vest, for example, a hook that serves as a horizontal support for the housing element 1 of the projection apparatus. The support mechanism, for example, in the form of a strap (Fig. 4-6), can also be attached to a removable element 3, made in the form of a rigid grip, enveloping the support 4, in contact with its rear part.

A device for presenting information works as follows. The projection apparatus, together with the device for carrying it, is delivered to the place of presentation of information, for example, advertising or educational.

The carrying device, namely the casing 2 or the removable element 3, are fixed on the housing element 1 of the projection apparatus. In this case, the casing 2 must cover at least two sides of the projection apparatus, for example, the upper or side, isolating the housing element 1 of the projection apparatus from the influence of the external environment, for example, precipitation.

After that, the removable element 3 of the carrying device is mounted on a vertically oriented support 4, for example, a person, so as to touch the back of the support 4, which will ultimately allow the projection apparatus to be rigidly mounted relative to the support 4, after which the presentation of information can be started by projecting it onto a surface, vertical or horizontal, serving as a screen.

Rigid fastening of the projection apparatus relative to the support 4, ensuring synchronous changes in the orientation of the support 4 and the projection device and minimizing the number of degrees of freedom of the elements of the device relative to each other and the device as a whole, for example, the projection apparatus from the support 4 will simplify the control of the device during operation, since will allow you to accurately calculate the angle of rotation of the support (or yourself) to the operator of the device, which corresponds to the angle of the image from the projection device, increasing the consumption sumer properties of the proposed device.

At the same time, when using the proposed design, the device operator always has his hands free, which will allow him to perform any additional manipulations, and to move the light spot from the projection apparatus, it is enough to turn in any direction, also leaving his hands and not risking dropping the projection apparatus and precisely controlling the angle of its movement, due to the provision of the necessary fixation.

Thus, the proposed device can provide a dynamic presentation of information, for example, in the process of presentation lectures, for showing video and animated films, while the device used has improved consumer properties, expressed in simplifying device management during operation, providing synchronous changes in the orientation of the support and projection apparatus while maintaining its isolation from external environmental influences .
