Description

The utility model relates to the field of construction and work under facing with finishing materials (tiles, artificial stone, porcelain tiles, wallpaper, painting, etc.) of bathrooms, toilets and other rooms of residential and industrial premises, where access to hidden communications (taps, pipelines, all kinds of meters, wiring devices, etc.). In particular, the utility model relates to a construction for facing with finishing materials for wall and floor installation.

A device is known for providing access to hidden communications (for example, pipelines, water flow meters, etc.) inside and outside rooms or buildings in the form of a removable door installed in a ceiling or wall opening, the surface of which is prepared for further cladding with decorative materials with its own thickness comparable but not exceeding the thickness of the wall surface sheathing made of drywall sheets (see the official website of Hammer Manufacturing Company, production and sale of inspection Yukov, located on the Internet at: http://www.xammer-luki.ru/).

However, such a device does not provide the possibility of lining the surface of the removable door with finishing materials with its own thickness exceeding the thickness of the drywall (i.e. more than 12 mm), for example, with artificial stone or porcelain stoneware, since such a door does not have sufficient bearing capacity with respect to the frame and the loops holding it in the opening. In addition, a removable door is fixed inside the opening using magnetic latches, which does not exclude its arbitrary loss from the technological opening.

Known solutions that provide access to hidden ones include utility models according to Russian patents No. 51390, E063 / 32, published on 02.10.2006 in Bulletin No. 4 and No. 57785 E063 / 32, published on 10.27.2006 in Bulletin No. 30.

So in these patents, inspection hatches are described for lining with finishing materials for ceiling, wall and floor installations, which include a hinged-mounted door on a box frame, a door bounding the hatch opening, made in the form of a frame supporting the door leaf, an shockless latch or lock device and door travel limiters fixing its position in the frame, while the door frame is hung on the frame by means of a double-lever hinge-link loop, comprising at least one vertical support arm, in filled with a length comparable to the length of the frame, and at least a pair of horizontal supporting arms rigidly connected to the vertical arm and connecting it to the frame and the frame by the door, and mounted in hinge supports mounted accordingly, one on the side of the frame, and the other is on the part of the door frame that is internal to the frame, and the door frame in the frame is fixed to a support mounted at the lower end of the door.

However, such useful models, due to the fact that they have a double-hinge lever loop, have a pair of fixed horizontal (70 mm) supporting horizontal

levers which do not have the ability to change (decrease - increase) along the length (a = 25 mm) and as a result do not provide:

1. Moving the door frame to the box frame in width and height;

2. The increase in the bearing capacity of the hinge-lever loop hatch revision;

3. Installation of a single gap (b = 3-4 mm) between the box frame and the door frame both in height and in width of the hatch;

4. Regulation of the amount of "sagging" (in = 2 mm) of the door frame with glued finishing material during operation of the hatch;

The objective of the proposed utility model is the development of a varying (adjustable) along the length of the construction of the supporting horizontal levers (four), the installation of a single gap between the box frame and the door frame and the amount of “sagging” of the hatch door frame under the lining with finishing materials, the implementation of which would provide an opportunity to increase the bearing the ability (up to 50 kg) of the hinge-lever loop and increase the warranty period of operation of the revision hatch from one year to five.

The technical result achieved in this case is to increase the operational and technical parameters and expand the assembly capabilities of the inspection hatch.

To solve this problem, the design of the revision hatch is proposed to be performed using two pairs of horizontal support arms assembled using studs with left-hand thread 9, studs with right-hand thread 4, union coupling with right and left-hand thread 6, and two lock nuts 5, 7, which provide change ( increase - decrease) the length of the construction of the supporting horizontal levers, while to increase the strength of the connection of the stubs of the thrust 12 (four) with the box frame 13 and the frame of the door 2, in addition to welding, use the power finger 23 (four).

At the same time, it is advisable that the change (increase - decrease) in the length of the structure assembled of two pairs of support arms does not exceed 25 mm.

It is desirable that the selected size of a single gap (b) does not exceed 4 mm, and the value of "sagging" (c) should not exceed 1.5 mm.

The specified technical result is achieved in that the inspection hatch for facing with finishing materials, comprising a box frame made of vertical and horizontal elements connecting them, a door pivotally mounted on a box frame, having a frame of horizontal and vertical elements connecting them, to which the door leaf is attached , a latch or a locking device and door travel limiters, fixing its position in the frame, while the frame of the door is hung on the frame by a hinge double lever hinge loop, comprising at least one vertical supporting arm and at least a pair of horizontal supporting levers that are rigidly connected to the vertical arm and connecting it to the box frame and door and mounted in hinged supports

using a power finger mounted respectively, one on the side of the box frame and the other on the vertical frame of the door relative to the box frame, and the door frame in the box frame moves in width and height, which allows you to choose the best lever to reduce static load those. increase the bearing capacity of the hinge-lever loop, install a single gap (b) and control the amount of "sagging" during operation, and at the lower end of the door frame in the closed position is fixed to at least one support movably mounted relative to the box frame.

These signs are significant and interconnected with the formation of a stable set of essential features sufficient to achieve the specified result.

This useful model is illustrated by specific examples, which, however, are not the only possible ones, but clearly demonstrate the possibility of achieving the above set of features of the required technical result.

In the framework of this utility model, the design of the inspection hatch for facing with finishing materials, and installed in bathrooms, toilets and other rooms of residential and industrial premises where access to hidden communications (taps, pipelines, all kinds of meters, wiring accessories, etc.) is considered .

The revision hatch for all examples of execution (Figs. 1, 4) comprises a box-shaped frame 1, which is an external rectangular-shaped frame consisting of vertical box-shaped elements (two) and horizontal box-shaped elements (two) connecting vertical box-shaped elements with each other.

The door frame 2 is rectangular in shape and consists of vertical elements (two) and horizontal box elements (two) connecting the vertical box elements to each other.

The frame of the door 2 is inserted inside the box frame 1. A frame is attached to the frame of the door 2, onto which the facing material (not shown) can be installed by known methods. The door is pivotally mounted on the box frame 1 by means of a double-movement hinge-link loop 14, comprising at least one vertical lever, consisting of a rigidly connected sleeve 17 (two) with a calibrated rod 15 and a tube 16, and at least a pair supporting horizontal levers, varying in length, assembled into a single design of a horizontal supporting arm, consisting of

studs with left-hand thread 9, studs with right-hand thread 4, union sleeve 6, lock nuts 5, 7, rigidly connected to the vertical lever 16 and connecting it to the box frame 1 and the frame of the door 2 and installed in the hinge supports 18 (four), consisting from a stubborn bracket 12, a sleeve 10, a rivet 11, a power pin 23 mounted respectively, one on a large rack of the box frame 13, and the other on the vertical element of the door frame 2, which is internal to the box frame.

The frame of the door 2 in the box frame 1 in the closed position is fixed to installed at the lower end of the door, at least one support 3, movably mounted relative to the box frame 1.

Also, on the frame 1, a latch 24 (two) is mounted or a locking device and door travel stops 25 (two) are fixed, fixing its position in the frame. The door travel limiters 25 are “scarves” welded at the corners or along one corner to the box frame 1 so that when closing the frame of the door 2 it rests against the scarf (two). The latch 24 is a stop with a profile outer surface, which when closing the door is inserted into the gap between the two support rollers. Such latches, depending on the length of the vertical elements of the frame 1, may be two or more on each side of the frame.

Figure 1 shows the first example of the execution of the articulated lever loop double movement.

The double-lever hinge link 14 includes a first vertical power lever 16, in the cavity of which a second power lever 15 is located. A rigid pair of horizontal support arms consisting of a pin with a left-hand thread 9, a pin with a right-hand thread 4 is attached to the first power lever 16 , with a sleeve coupling 6, lock nuts 5, 7, the other ends of which are pivotally connected to the vertical element of the box frame 13. To the ends of the second vertical power lever 15 that exit from the cavity of the first power lever 16 are rigidly fixed about bushings 17 to which a pair of other horizontal support arms is rigidly attached, consisting of studs with left-hand thread 9, studs with right-hand thread 4, union sleeve 6, lock nuts 5, 7, the other ends of which are pivotally attached to the vertical element of the door frame 2. Thus, when the hatch door is opened, the latter first moves plane-parallel from the frame due to a rotation around the axis of the first vertical power element 16, and then opens like an ordinary hinged door to the required angle, for example 90 degrees.

Hinged connections are hinged supports 18 with the possibility of rotation of one part relative to another around a vertical axis.

Figure 4 presents the second example of the execution of the articulated lever loop double movement.

In this embodiment, the double-movement hinge-link loop 14 includes a first vertical power arm 16, in the cavity of which a second power arm 15 is located. A rigid pair of horizontal support arms consisting of a left-hand stud 9, a stud, is attached to the first power arm 16. with a right-hand thread 4, a sleeve coupling 6, a lock nut 5, 7, the other ends of which are rigidly connected to the third power lever 26, fixed with bushings 17 (two) on the frame of the door 2. To the ends coming out of the cavity of the first power lever 16 The other power arm 15 is rigidly fixed in the bushings 17 (two), to which a pair of other supporting arms is fixed at an angle of 40 degrees, the other ends of which are connected by means of a bolt connection consisting of a bolt 21, a sleeve 20, a washer 22 with a box frame 1 of the hatch revision. Thus, when opening the door of the hatch, the latter first moves parallel to the frame 1 parallel to the axis of the bolt connection of the second power lever, and

then opens like an ordinary door by means of a third power lever 26, at the desired angle, for example 180 degrees.

The proposed utility model works as follows:

After the manufacture of the box frame and the door frame, the assembly of the revision hatch structure is assembled using an articulated lever loop, a latch with a latch, and installation of the slab according to the size of the hatch door frame.

The assembled design of the inspection hatch is installed in the technological opening and is exposed in the same plane with the wall, it is fastened with self-tapping screws through the mounting holes. Then, the lining of the hatch door is lined with finishing materials with an “inlet” and preservation of a single inter-tile seam. Rotating the horizontal support arm (two) with a sleeve coupling, we move the frame of the hatch door in height and width i.e. we establish the optimum lever of the hinge of the hatch, a single gap between the box frame and the frame of the door and the amount of “sagging” of the hatch door. Then fixation with lock nuts.

Using suction cup handles or stationary handles, the hatch door with glued cladding material opens “onto itself” and leaves the technological opening, then it opens 90 or 180 degrees like an ordinary door, providing access to hidden communications.

This utility model is industrially applicable, as it can be implemented using profile elements, standard fasteners and conventional technologies that are used for procurement and assembly work.
