Description

The invention relates to the designs of complexes as part of an optically opaque partition between space A and space B, and surveillance and/or video surveillance and/or video recording devices that allow viewing space A from space B. The primary purpose is domestic and prison doors with peepholes, fixed partitions (walls), testing and technological chambers.

Known bolts with a central through hole [1. Bolt 10 mm with inner hole / Fig. [Electronic resource] - URL: Hf5f3d43fb8a34e3fa52b2eb2040a105f8.jpg]. "Hollow" bolts will be used in cases where it is advisable to lighten them due to their large size, or when it is necessary to pass something through them (for example, a cable), or for both of these reasons at the same time. Of course, while maintaining the performance of the bolt of its main function - fastening.

However, they are only the basis for specific applications as part of certain constructs.

Known optical surveillance devices and/video recordings, including embedded in the door "door pupils" [2. RU 2315343 C1, IPC G02B 25/04, 01/20/2008, "Door peephole (options)"; 3.. RU 2149517 C1, IPC; H04N 5/33; H04N 7/18, "CCTV system for the area in front of the front door)"].

However, they are single-functional: they are used only for the optical interconnection of spaces A and B, separated by a partition.

Название «штуцер» используют, чтобы выделить патрубки с резьбовым соединением среди прочих и чтобы отличить таковые с наружной резьбой от таковых со внутренней, называя последние «патрубками» с гайкой.There are various fittings (pipes) with cut wrench heads that are threaded into through holes in metal structures (casings, crankcases) to enter the internal space from the external space or remove liquid (water, oil, fuel, etc.) from it. , gas, etc. [4. Union. - URL: https://ru.wikipedia.org/wiki/Main_page (date of access: 06/14/2022); 5. Uponor Q&E male 25-G3/4''HP (1047862)-1048

- URL: pipes-shop.ru (date of access: 06/08/2022). The name "nipple" is used to distinguish threaded fittings from others and to distinguish those with male threads from those with internal threads, calling the latter "nipples" with a nut.

However, they are single-functional, do not participate in the screeding of metal structure parts and require the allocation of additional areas and volumes for them.

Known LED lamps (slots) on the bolt [6. Bolt-on LED slots. - URL: https://ledpremium.ru/catalog/spoty_na_bolte/svetodiodnyy_spot_na_bolte_d23_2w_black_12v_23mm_chernyy (date of access: 06/08/2022)].

In fact, these are LEDs partially embedded in a through central hole in the bolt, while the latter is used to mount the lamp on any structure.

However, such devices are “one-sided” (it is located in the same space and illuminates this space) and do not carry the function of screeding parts of the structure, which is characteristic of a bolted connection.

The closest analogue to the claimed device in terms of purpose and set of essential design features (prototype) is a complex of a partition and an observation device containing a partition with a bolted connection of at least two of its layers between space A for the observer and space B for the object of observation, and a through hole for installation observation devices, and an observation device as part of coaxial optical elements, including an eyepiece, an objective and intermediate lenses, built into a cylindrical metal body with an external thread at one end and with an end thrust head at the other end with a tool tie device, a housing rotation lock and an axial body retainer, provided with an internal thread, the response in relation to the said external thread [7. What are door eyes / Ruslan Polishchuk. - URL: https:// legkovmeste.ru/stroitelstvo-i-remont/dveri/glazok-dvernoy-panoramnyiy.html (date of placement: 08/03/2018; accessed date: 06/08/2022)].

In the prototype, the partition (the front door of the living quarters) is made, as a rule (as befits such products), at least two-layer - with a base steel sheet and a decorative non-metallic layer, while the layers (cloths) are connected to each other by bolted or screwed, along the perimeter of these layers (cloths). The body of the observation device is assembled at the place of installation - from two cylindrical parts ("ocular" with an external threaded section and "objective" with an internal threaded section) and screwed, by means of these threads, directly in the opening of the partition simultaneously from the sides of spaces A and B, up to their total length in accordance with the thickness of the partition. To do this, slots for a screwdriver are provided on the end thrust heads as a device for a tool coupler of these parts of the housing. In terms of external dimensions and material, the body is made as an original product, structurally and geometrically different from standard bolts (with nuts) or screws for connecting layers (cloths) of the partition. The optical device is distributed, as we see, between these two parts of the body. In this case, the coaxial optical elements, judging by the illustrations given in the source [7], are rigidly installed in the housing. An eyepiece shutter is provided, which is recognized as an “optional element” and has no fundamental significance in determining the subject of discussion.

However, in the prototype [7], both the partition and the observation device are also single-functional: each of these components of the complex of the partition and the observation device perform only the functions corresponding to their intended purpose and name (the partition partitions off rooms A and B, the observation device provides the ability to observe the situation in room B from room A). This means that the organization of the observation device is associated with the allocation of additional area and volume “under it”, which is especially problematic in small-sized test and technological chambers with flange structures, chambers with a large pressure drop in spaces A and B. While there remains the problem of the sufficiency of the number and size of the tie bolts of the partition layers. To tie the layers of the partition, a different tool is required.

All this narrows the technical and operational capabilities (TEV) of known complexes, does not fully correspond to the design principle of unification.

This implies the task of the claimed invention: the creation of a complex of a partition and a surveillance device (a set of essential design features of the complex), partially or completely devoid of these shortcomings of the prototype and other analogues.

In another, general formulation, it is to expand the TEV of the complex by enabling the baffle to perform the additional function of the axial lock of the body, and the observation device - the additional function of tightening the layers of the baffle, and with the same tool of the same standard size.

The indicated problem is removed (the problem is solved), with the technical result that in the complex of the partition and the observation device, containing the partition with a bolted connection of at least two of its layers between space A for the observer and space B for the object of observation, and a through hole for installing the device observation, and an observation device consisting of coaxial optical elements, including an eyepiece, an objective and intermediate lenses, built into a cylindrical metal body with an external thread at one end and with an end thrust head at the other end with a tool tie device, a housing rotation lock and an axial lock of the housing provided with an internal thread, reciprocal with respect to the said external thread, according to the claimed invention, the body of the observation device is made in the form of a bolt with a faceted end stop head for a wrench as the said tool tie device, and the mentioned reciprocal internal the thread is made in the mentioned through hole, at least in the layer of the partition, which is extreme from the side of space B, with the possibility of the partition performing the additional function of the axial fixation of the body, and the observation device - the additional function of tightening the layers of the partition, and with a tool of the same standard size.

The technical result (in accordance with the task) is also achieved due to additional features of the claimed invention, forming four sets of them:

- the bolt-body can be made identical to the mentioned bolted connection of the partition layers in terms of external dimensions and material (this rationalizes the design due to the implementation of the principle of unification in it as one of the engineering guidelines);

- coaxial optical elements can be installed in the housing by means of elastic gaskets, at least tubular, and gaps between the optical elements and the housing, with the possibility of reducing the effect of stresses in the tightened housing bolt (this further improves the image quality through the observation device, by compensating for the indicated stresses in the bolt housing);

- the partition can be made either movable, for example, in the form of a door, door or cover, or fixed, for example, in the form of a wall (in the first case, this expands the capabilities of more common complexes with movable partitions, in the second, less common fixed partitions).

A clear distinction between the restrictive and distinctive parts of the given sets of essential features, reflecting the results of a comparative analysis of the proposed device with the prototype, correlates with the world level of novelty of the technical solution. The world level of novelty is the first of the triad of features (criteria) of an invention.

Further, for all its brevity of the wording, the totality of the distinctive essential features of the claimed means of salvation is not a simple sum of the known technical results of using separately known components of the device. There is a "super-effect" (in the patent meaning of this term), which was not obvious to a specialist from the state of the art (of course, before considering the proposed technical solution). With a whole range of additional technical and operational capabilities. This convincingly demonstrates inventive development as the second of the triad of invention qualifications.

The third qualification feature - industrial applicability - is also indisputable and follows, first of all, from the same accumulated experience in the design, production and operation (practical use) of various sea rescue equipment.

The claimed complex is explained, in addition to the description and operation (functioning) below in the text, by drawings:

in fig. 1 shows the inventive complex, side view with local cuts, where A is the space with the observer, B is the space with the object of observation;

in fig. 2 - observation device, side view in section;

In FIG. 1, 2 positions are marked: 1 - partition; 2 - partition layer from the side of space A; 3 - partition layer from the side of space B; 4 - coupling bolts for connecting the layers of the partition; 5 - through hole in the partition 1; 6 - surveillance device; 7 - eyepiece; 8 - lens; 9 - intermediate lenses; 10 - housing of the surveillance device; 11 - external thread on the body; 12 - body head; 13 - device (hexagon) of the instrumental screed with the body of the partition layers; 14 - lock against rotation of the body; 15 - axial lock of the body; 16 - internal thread in the partition; 17 - elastic gaskets between the optical elements and the body; 18 - local (local) gaps between the optical elements and the case; 19 - technological hole for installing the rotary shutter of the eyepiece; 20 - rotary shutter of the eyepiece.

The complex of a partition and an observation device (hereinafter referred to as the "complex") contains a partition 1 with a bolted connection of at least two of its layers - 2 and 3, respectively (in the drawings - from left to right) between space A for the observer and space B for the object of observation.

Said bolted connection includes a plurality of bolts 4, as a rule, distributed along the periphery of the layer of smaller area (in the case of layers with unequal area, while in the case of their equal area along the periphery of both). The power screed of layers 2 and 3 is provided either by an internal thread in layer 3 from the side of space B, or by a nut from the side of space A (to avoid unauthorized unscrewing from the side of space B).

A through hole 5 is made in the partition 1 for installing a surveillance device 6 (including, possibly, video surveillance, video recording).

The observation device 6 includes coaxial optical elements, including an eyepiece 7, a lens 8 and intermediate lenses 9, built into a cylindrical metal body 10 with an external thread 11 at one end (left in the drawings) and with an end stop head 12 at the other end ( on the drawings - on the right). The head 12 is made with a tool tie device 13 (for more details, see below).

A latch 14 is provided to prevent rotation of the body 10 (can be made, for example, a pin, in the form of a screw or in the form of a folding washer under the head 12, which is not essential here) and an axial latch 15 of the body 10. The latch 15 is provided with an internal thread 16, mating with respect to external thread 11 (see details later in the text).

The body of the observation device 6 is made in the form of a bolt with a cut (mainly hexagonal) of the end thrust head 12 for a wrench as a device 13 of the tool coupler of the "bolt-shaped" body 10 with a partition 1. The mating internal thread 16 is made in the hole 5, at least in the extreme on the side of space B, layer 3 of the partition 1, with the possibility of the partition 1 performing the additional function of the axial lock of the body 10, and the observation device 6 - the additional function of tightening the layers of the partition 2 and 3, with a tool (wrench) of the same size.

Further description of the device extends to special cases (examples) of the device.

The "bolted" body 10 can be made identical to the "coupling" bolts 4 connecting layers 2 and 3 of the partition 1 in terms of external dimensions and material (steel);

Coaxial optical elements 7-9 can be installed in the body 10 by means of elastic gaskets 17, at least tubular, and gaps (system of local gaps) 18 between the optical elements 7-9 and the body 10, with the possibility of reducing the effect of stresses in the tightened "bolted" case.

To avoid condensation in the cavity(s) of the observation device 6, the gaskets 17 are split (with drainage channels (not shown).

Partition 1 can be made either movable, for example in the form of a door, door or cover, or fixed, for example in the form of a wall.

A technological hole 19 can be provided on the head 12 for installing a rotary (in a transverse plane with respect to the main optical axis of the observation device) shutter 20 of the eyepiece 7. It is also possible to mirror the lens 8 from the side of space B.

The device (complex) works (functions, use) as follows.

Bolts 4 tighten layers 2 and 3 of partition 1 between themselves.

The observation device 6 in the initial state is closed by a damper 20 to prevent unauthorized reverse observation - from space B to space A.

The "bolt-shaped" body 10 of the observation device 6, previously (when mounting the device 6 in the partition 1) screwed with an external thread 11 of the body 10 into the internal thread 16 of the layer 3 of the partition 3, and tightened with a wrench through the head 12 with the device 13 (cutting), simultaneously fixes observation device 6 in the hole 5 of the partition 1, and participates, along with the bolts 4, in the connection of its layers 2 and 3 (this is the main thing in the described technical proposal).

The longitudinal stresses arising in the body of the body 10 are mainly partially compensated (smoothed) by the system of seals and local gaps with optical elements 7-9, reducing their influence on the image quality to an acceptable level. Since in this case the optical system 6 is not a microscope, telescope or sight, the image quality requirements are not so great.

In the observation mode (video surveillance, video recording) from space A of the situation (object of observation) in space B, open (by turning and fixing by friction) the shutter 20 and observe (at the level of the main optical axis of the observation device 6) the situation (object of observation) in space B, thanks to the optical system 7-9. If there is a video surveillance system and / or video recording, video surveillance and video recording of the image are carried out, respectively.

The latches 14, 15 and the location of the head 12 in space A do not allow unauthorized removal of the monitoring device 6 from the hole 5 from the side of space B.

The technical result consists in expanding the technical and operational capabilities (TEV), namely, enabling the partition to perform the additional function of the axial fixation of the body, and the observation device - the additional function of tightening the layers of the partition, with the same tool of the same size.
