Description

CHALIT SET
Field of the invention:
The present invention relates to an aluminum bedstead assembly.

description of the prior art
Classic bedsteads are generally made of wood, steel or copper. Due to their weight and strength, the components of the beds are assembled and fixed in factories before delivery. The space occupied by the assembled beds is therefore considerable, and one cannot pack these beds like ordinary articles. Likewise, it is difficult to move a large and heavy bed freely. Nowadays, as people are attracted to the "do it yourself" fashion, there is a demand for a light bedstead set with sufficient strength that can be easily packed.

 In addition, existing bedstead assemblies must be secured with screws using a screwdriver. In some sets, you have to drill holes to adjust the height of the bedstead, which is boring and time-consuming.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The bedstead is composed of a set of a plurality of columns and aluminum plates, preferably comprising four vertical columns (1), eight first connecting elements (2), four first lateral elements (3), four second elements side (4), eight positioning elements (5), eight studs (6), eight second connecting elements (7), four spacers (8) and four covering elements (9).

 Each vertical column (1) has a plurality of notches (11) as well as two grooves (12) separated by a right angle. Each groove (12) is designed to be narrower towards the outside and wider towards the inside in order to form a vertical insertion space (121). A plurality of insertion grooves (14) is provided on the periphery of the vertical column (1) in order to receive a plurality of plates (15) of the pull-out type.

 The first connecting element (2) consists of a plate (21) provided with two parallel vertical plates (22) placed in suitable places. A side end of each vertical plate (22) projects outward to form a flange (23), so that each plate (22) can be inserted through any end of the groove (12) of the column (1), thus preventing the two vertical plates (22) from horizontally disassembling the grooves (12). Two perforations (24A) and one perforation (24B) are provided in the plate (21).

 The first side element (3) which has a hollow rectangular section and a longitudinal reinforced element (31) is arranged on its inner side. A flange (32) projects from one side of its lower end, and on the same side as the first lateral element (3), screw holes (33) are also provided in predetermined locations, while a first screw (34) oriented in a vertical direction is provided on the other side of said element. A second screw hole (35) oriented in a vertical direction is also provided on the other side. The first (34) and second (35) screw holes of the first lateral element (3) as well as the corresponding perforations (24A) of the first connecting element (2) are connected together by screws. of inverted U extends along the upper side (36) of said element to form a first longitudinal insertion space (371). Furthermore, this inverted U-shaped element (37) rises above the lateral side (36) and the inverted U-shaped element (372).

The second side element (4) is also a hollow rectangular structure. A third screw hole (41) oriented in a vertical direction is provided on one side of the lower end of this element. The third screw hole (41) as well as the perforation (24B) of the first connection element (2) are connected together by a screw. A U-shaped member (42) extends upward from this side member to form a second longitudinal insertion space (421) such that the groove (422) of this U-shaped member (42) as well as the groove of the inverted U-shaped element (37) are located opposite one another in the longitudinal direction
The positioning elements (5) consist of a connecting section (51), the two ends of which extend perpendicularly from this section to form two L-shaped sections (52). A perforation (53) is provided at a predetermined location of the connection section (51) in order to be able to connect it to the perforation (33) of the first lateral element (3). Likewise, a lower end of this positioning element (5) comes into contact with the rim (32) of the first lateral element (3).

 The tenon (6) consists of a plug (61) and a block (62), the plug (61) being engaged in an insertion space (73) located at each end of the connecting element (7), the block remaining outside after insertion of the plug (61).

 As regards the plurality of second connection elements (7), each of these has a central connection part (71), two second grooves (72) as well as two second flanges (73). The two second grooves (72) extend on one side of the central connecting part (71) to engage vertically in the L-shaped sections (52) of the positioning elements (5) and to further prevent these elements to disassemble horizontally. Likewise, two second flanges (73) extend on the other side of the central connection part (71). These second flanges (73) are substantially parallel and are spaced apart from each other.

 The spacer (8) is a hollow rectangular longitudinal structure. Edges are respectively provided on the inner and outer sides of the upper part of this spacer (8). The height between the external support flanges (81) and the upper side is equivalent to that between the upper side (36) of the first lateral element (3) and the upper side of the inverted U-shaped element ( 37) so that the bed plates (86) can be inserted horizontally between the upper side (36) of the first lateral element (3) and the external edges (81) of the spacer (8). The inner edges (82) and the upper side of the spacer (8) form the insertion space (83) intended to receive the plug (61) of the stud (6). The width of the section of the spacer (8) is equivalent to that of the two second flanges (73) of the second connecting element (7), so that the spacer (8) can be inserted between the two second flanges (73), the two flanges of external supports (81) coming into contact with the upper side of the second connection element (7). Then, the second flanges (73) and the positioning element can be firmly assembled using pins.

 The covering element (9) has an opening (92) as well as a plurality of projections (91) intended to be inserted in the notches (11) formed on the upper side of the vertical column (1). The periphery of this element (9) covers part of the upper side of the first lateral element (3) when it is attached to it.

 With reference to FIGS. 1 and 2, a bed frame (100) consists of four vertical columns (1), eight first connecting elements (2), four first lateral elements (3), four second elements (4) as well as eight positioning elements (5). Each spacer assembly (200) includes two studs (6), two second connecting elements (7) and a spacer (8).

 As shown in Figure 2, the third screw hole (41) of each end of the second side member (4) and the perforations (24B) of two of the first connecting members (2) are connected together by screws. A decorative plate (39) is inserted through its lower end into the second longitudinal groove (421) of the U-shaped element (42). After having fixed the first longitudinal groove (371) of the inverted U-shaped element (37) of the first lateral element (3) on the upper edge of the decorative plate (39), the first (34) is adjusted together and the second (35) screw hole of the first lateral element with the corresponding perforations (24A) of the first connecting element (2).

Thus, four first lateral elements (3), four second lateral elements (4), eight first connecting elements (2) as well as four decorative plates (39) form a complete side of the bedstead. A plurality of positioning elements (5) are respectively screwed onto the corresponding perforations (33) of the first lateral elements (3) by means of screws passing through the perforations (53).

 Then, the longitudinal plates (22) of the first connecting elements (2) at the two ends of the above-described side of the bed frame are inserted into the vertical grooves (21) of the corresponding grooves (12) of the columns (1). A base (16) of base and a foot (17) are placed at the lower end of each column (1) so as to protect it. Then, decorative plates (15) of various colors and grain extractable by drawing, are inserted in grooves (14) formed at the periphery of each column (1). Finally, the projections (91) of the covering element (9) are inserted into the upper part of the plurality of grooves (11) of the column (1), so that the edge of the covering element (9) covers the upper part of the first two lateral elements (3), thus protecting the columns of the bed. Similarly, as a result of the presence of an opening (92), a continuous space is formed along the upper side of the first lateral element (3 ).

 In addition, several pins (6) are inserted by their plug (61) into insertion spaces (83) located at each end of the spacer (8), so that their blocks (62) are turned towards the outside. Each spacer (8) is fixed between the two second longitudinal edges (73) of the second connecting elements (7) which have the same height as the spacer (8). The two external support flanges (81) are in contact with the upper side of the second connection element (7). The L-shaped sections are then inserted into the second grooves (72) of the second connection element (7). (52) of the positioning element (5), the lower end of the latter pressing against the flange (32) of the first lateral element (3), as well as the block (62) of the tenon (6 ) comes to rest on the upper side (36) of the first lateral element (3), forming a horizontal support frame for the bedstead.

 Before leaving the factory for delivery, some of the items must first be assembled. For example, it is possible to assemble a first lateral element (3), a second lateral element (4), a decorative plate (39) as well as two first connecting elements (2) in order to form a simple unit intended for work of subsequent assembly. One can also attach together the pins (6), the spacers (8) and the second connecting elements (7) to form four sets of spacers (200) which constitute the four entire horizontal support plates of the bedstead. this way, the user only needs to assemble the four units and the horizontal support plates of the bedstead in the four vertical columns (1) and in the positioning elements (5), and also to place a plurality of bed (86) on the spacers (8) to complete the assembly process, without the need for tools.

 The four sides of the bedstead are assembled as described above, and the assembled rectangular bedstead as shown in Figure 2. There are many other possible variants. For example, it is possible to apply a structure of ribs to the first lateral element (3) or to the spacer (8). Likewise, an auxiliary support rod can be inserted into the interior hollow space of each first lateral element (3) or into the space of each spacer (8) in order to reinforce the entire structure.

 There are a variety of embodiments of the bedstead according to the present invention. For example, one can make screw holes in the lower side of the columns (1), these holes being intended to receive legs provided with screws in order to adjust the height of the bedstead.
