Description

The utility model relates to the production of collapsible metal frames or bed frames and can be used in the manufacture of beds or other sitting or lying furniture made of metal pipes.

The problem of making collapsible metal frames and bed frames has existed since the advent of metal beds and remains relevant today.

The fact is that such collapsible products are more transportable, but for reliable operation they require strong connecting nodes.

Known metal frame (RU, 200055, A47C 19/00, 05/10/2020) for installing a mattress of upholstered furniture, containing a frame and elastic elements fixed to the frame, which is formed from a metal profile with a constant cross-sectional shape and made with end sections , connected to each other to form a closed frame, characterized in that the connected end sections of the profile are made with the possibility of installing one of these end sections in the hollow other end section, ensuring direct contact of the mating surfaces of the connected end sections.

The disadvantage of such a connection is that connecting elements are required to connect the end sections of the frame, which increases the cost of the structure. In addition, this design does not provide for fixing the connected ends of the frame pipes from arbitrary disconnection.

Also known is the pipe fastening assembly (RU, 2210012, F16D 12/44, publ. 08/10/2003). The assembly contains a fastening element and an element for fixing the first end of the fastening element inside the first pipe, in the wall of which a through hole is made for the fastening element. The second pipe has at least two wall parts opposite each other and parallel to each other. The fixing element of the second end of the fastening element is located inside the second pipe, and at least one groove is made in the first pipe to accommodate the end of the wall of the second pipe. The groove is located transversely to the length of the first pipe. Increases the operational reliability of the unit.

The disadvantage of the connection is that in order to connect the pipes, two additional parts must be made: a washer and a spacer sleeve. In addition, grooves must be made in one pipe by milling, and two adjacent walls must be cut off on the other pipe. Welding the washer in the pipe requires welding. The connection in production is structurally complex and, as a result, expensive.

The closest analogue, taken as a prototype, is a collapsible metal bed frame (RU, 189335 U1, A47C 19/12, publ. 05/21/2019), designed to accommodate a soft base for sitting or lying on it, containing metal pipes connected with the possibility of separation and liners, made by means of two metal U-shaped pipes and two straight pipes connected with the possibility of separation, and the pipes are connected to each other in such a way that each end of each straight pipe is connected to one of the ends of the U-shaped pipe, while in the assembled position, the frame is a rectangle, through holes are made at the ends of the pipes near the junction, and an insert with holes is installed at each pipe connection point inside the pipes, corresponding in shape to a part of the cross-section of the pipes to be connected at the place where the holes are made, where the holes in the insert coincide with the holes on ends of pipes, and a detachable connection is formed through the use of furniture bolts installed in the holes of the pipe ends and liners.

The disadvantages of this design are determined by the fact that the pipes are connected using many structural elements: threaded inserts and bolts, as a result of which this product is structurally complex, and its assembly requires high labor costs and highly qualified personnel.

The task solved with the help of this utility model is the creation of a structurally reliable, easy-to-use metal bed frame.

The technical result is to simplify the design by reducing the nomenclature of connection parts; the connecting unit (semi-frame with a transverse profile) does not have bolted connections and corresponding insert parts.

The technical result is achieved by using in a known design a collapsible metal frame of the bed, consisting of two half-frames and two transverse profiles, a pipe-to-pipe connection by means of a modified internal profile size of one of them by means of reduction (Reducing the pipe end, that is, reducing the size of the profile or, on the contrary, expanding the pipe (increasing the profile size) for effective coupling). This is achieved by a flat area formed in the course of reduction, wider than the diameter of the cap of the exhaust nut, and located below the inner surface of an uncompressed (non-reduced) pipe at least to the height of the cap of the exhaust nut. In the connection, the number of pulling nuts with thread size M6 or M8 varies from 1 to 2.

The utility model is illustrated by the following drawings:

FIG. 1 is a general view of a collapsible metal bed frame;

FIG. 2 - pipe-to-pipe connection of a semi-frame with a transverse profile.

The collapsible metal frame of the bed is a prefabricated structure of two half-frames (1), two transverse profiles (2) (Fig. 1). Semi-frames (1), transverse profiles (2) are made of square metal pipes. The connected end sections of the pipes are made with the possibility of installing one of these end sections in the other, ensuring a tight connection (Fig. 2) "pipe to pipe", due to the reduced (compressed) end of the transverse profile (2) with the formation of a flat area (3) , the width of which is greater than the diameter of the chimney nut head (4), and located below the inner surface of the uncrimped pipe by at least the height of the chimney nut head

Thus, as a result of the implementation of the utility model, the fulfillment of all the tasks set by the authors is achieved. The connection of the half-frames with a cross-section is simple, strong and reliable.

Claims (1)

A collapsible metal bed frame, consisting of two half-frames and two transverse profiles made of metal pipes, the connected end sections of which are installed one into the other, characterized in that the inserted end section of the pipe is made reduced to form a flat platform with a width exceeding the diameter of at least one cap of the exhaust nut, and a height less than the inner diameter of the unreduced pipe by at least the height of the cap of the exhaust nut.
