RU234427U1 - Greenhouse door unit - Google Patents

Abstract

The utility model relates to gardening, to growing flowers, vegetables, berries, etc. in hotbeds and greenhouses, to the designs of ventilation devices - doors and vents. The utility model solves a technical problem - eliminating the need to use seals to ensure air insulation of the interior of a greenhouse. For this purpose, the door frame and door, the under-vent lintel and the lower part of the vent frame are made of a profile pipe with a rectangular cross-section with one of the profile corners molded inward (in construction terms - "with a removed quarter"). At the same time, when the openings are closed, these profiles form a rectangle (a "quarter-to-quarter" connection).

Description

The utility model relates to gardening, to growing flowers, vegetables, berries, etc. in hotbeds and greenhouses, to the design of ventilation devices - doors and vents.

Greenhouses with door blocks made of rectangular pipes are widely known, for example, the door block of the Novator greenhouses - Novator-Premium, Novator-Titan, Novator-Gost, etc. https://novator18.ru/catalog/teplici, including a door frame, a door frame hinged on it, in which a window frame made of a rectangular metal profile of a closed section, opening handles and closed position locks are hinged. This door block is taken as a prototype.

The general essential features of the prototype, coinciding with the essential features of the proposed technical solution, are the following: a door unit of the greenhouse, including a door frame, hingedly fixed to it and equipped with a lintel, a door frame, in which a window frame made of a closed-section metal profile is hingedly fixed, and opening handles.

This prototype door unit has non-removable gaps between the frames, which necessitates additional seals to ensure acceptable air insulation of the greenhouse interior.

The utility model solves a technical problem - eliminating the need to use seals to ensure air insulation of the internal volume of the greenhouse.

In order to solve the said technical problem, in the door unit of the greenhouse, which includes a door frame made of a closed-section metal profile pipe, a door frame hingedly attached to it and equipped with a vent lintel, in which the vent frame is hingedly attached, as well as opening handles, unlike the prototype, the door frame and door, the vent lintel and the lower part of the vent frame are made of a profile pipe with a rectangular cross-section with one of the corners of the profile molded inward (in construction terms - "with a removed quarter"), forming a rectangle when the opening is closed (a "quarter to quarter" connection).

The distinctive features of the proposed technical solution from the known (prototype) are the following - the door frame and door, the under-vent lintel and the lower part of the transom frame are made of a profile pipe with a rectangular cross-section with one of the corners molded inward, forming a rectangle when the opening is closed.

Due to the presence of the specified distinctive features, the following technical result is achieved - due to the above "selected" (concave in the rolling process) quarters, when closing quarter to quarter, the frames fit tightly to each other, which eliminates most of the gaps "on the light" (they remain only on 3 sides of the window), and therefore allows you to do without seals, and in addition, the very area of contact of the rebate (the length of the gap, which in this case becomes zigzag) is significantly increased. Also, for the door and window frames, the need for structural stops (limiters) to prevent the door frame from being pressed into the greenhouse is eliminated.

The proposed technical solution can be used in the construction of greenhouses and hothouses for various agricultural purposes. This door unit can either be included in the greenhouse kit initially or supplied separately for installation, for example, in the end part of the greenhouse, where there was no door before, or to replace an existing less hermetic one. Naturally, the delivery kit may include brackets for fastening to the greenhouse frame.

The described device is illustrated in Fig. 1-4.

Fig. 1 shows the end part of the greenhouse (without a translucent fence, for example, cellular polycarbonate) with a door block installed in it and a rotary window made in it.

Fig. 2 shows the end part of the greenhouse (without a translucent fence, for example, cellular polycarbonate) with a door block installed in it and a hinged window made in it.

The end part 1 of the greenhouse frame shown in Fig. 1, 2 includes a door unit 2, which can be either initially supplied with the greenhouse or installed instead of the standard unit or in addition (if it is absent in the end part). The door unit includes a door frame 4, a door frame 5, a vent frame 6 (rotary - Fig. 1 and folding - Fig. 2). The door frame is provided with a vent lintel 16. The door unit is installed in the end part 1 of the greenhouse frame using brackets 3. The folding vent 6 is provided with an open position lock 18.

The door unit 2 of the greenhouse shown in Fig. 1-4 includes a door frame 4, a door frame 5 and a vent frame 6 hingedly attached to it, made of a metal profile pipe, opening handles with closed position locks 11 and 13. The door unit 2 can be either a part of the end 1 initially, having standard fasteners, or, for example, installed in the "blind" end part 1 using brackets 3 and other fasteners (not shown in the figures). Frames 4-5, under-vent lintel 16 and lower part 17 of the vent frame 6 are made of a profile pipe 8-9 with a cross-section in the form of a rectangle with one of the corners of the profile molded inward (in construction terms - "with a removed quarter"), forming a rectangle when the opening is closed (a "quarter to quarter" connection). The upper and side parts of the window frame 6, as well as the stiffener 14, can be made from a closed profile of any cross-section (in this case, a rectangular profile pipe 10).

The door frame 5 is mounted on the door frame 4 in a hinged manner using hinges 7, and is also provided with a handle with a closed position lock 11. The window frame 6 is mounted on the door frame 5 in a hinged manner using hinges 16, and is also provided with a handle with a closed position lock 12.

In section A-A of Fig. 3 the following are shown: profile pipe with a quarter of door frame 8 removed, profile pipe with a quarter of door frame 9 removed, door handle with closed position lock 11, and polycarbonate 13. In section B-B of Fig. 3 the following are shown: profile pipe with a quarter of under-ventilation lintel 17 removed, profile pipe with a quarter of lower part of vent frame 17 removed, vent handle with closed position lock 12. In section C-C of Fig. 3 the following are shown: profile pipe with a quarter of door frame 8 removed, profile pipe with a quarter of vent frame 10 removed. In section D-D of Fig. 3 the following are shown: profile pipe with a quarter of door frame 8 removed, profile pipe with a quarter of door frame 9 removed. In view E of Fig. 3 shows the bracket for fastening the door block to the end part of the frame 3 and the hinge loop for fastening the door frame to the door frame 7. In section F-F of Fig. 3, the profile pipe with a removed quarter of the door frame 8, the profile pipe with a removed quarter of the door frame 9, the rectangular profile pipe of the vent frame 10, the hinge loop for fastening the door frame to the door frame 7 and the hinge loop for fastening the vent frame to the door frame 15 are shown. In section G-G of Fig. 3 shows a profile pipe with a removed quarter of the door frame 8, a profile pipe with a removed quarter of the door frame 9 and a hinge for attaching the door frame to the door frame 7. To increase the rigidity of the door frame 5, it contains a stiffener 14 (its profile is not important, in this case it is of square cross-section). In all corners of frames 4-5, the profiles are joined orthogonally and symmetrically relative to the plane of the connection.

The above-described door block 2 can be supplied in the form of welded frames 4-5 from profile pipes with selected quarters and frame 6, but can also be assembled by the consumer from separate linear parts using brackets, corners, etc. The welding option is preferable, since it also allows increasing the rigidity of the block frames. This door block can be installed, for example, at the end of a greenhouse to replace the existing one or be included in the installation kit of a new greenhouse.
