Description

A combination sofa with adjustable oblique back

Technical field:

The utility model relates to the field of sofas in furniture, in particular to a detachable combined sofa which can adjust the inclination of the backrest.

Background technique:

The sofa is a common furniture item, and it is usually a necessary piece of furniture in the family. Some improvements to the sofa are mostly in the design of the appearance. As for its structure, there is generally no major improvement. It is all made up of a seat and a backrest, and then a cladding layer made of a soft material is added to the structure. Due to the large size and weight of the sofa itself, it is very inconvenient during moving or transportation, and the angle between the backrest of the sofa and the seat is fixed and cannot be adjusted, so it cannot be adjusted according to the needs of the user. The most suitable angle makes the human body feel comfortable.

Invention content:

The purpose of the utility model is to provide an ideal sofa with an adjustable and detachable oblique back, which is convenient for transportation, saves freight, is easy to move into the narrow door of the apartment, and is easy to assemble by improving the prior art. Especially for export, the capacity of sea containers can be increased by 80%, which not only saves sea freight but also improves competitiveness.

In order to achieve the above object, the utility model is realized through the following technical solutions:

The utility model is mainly composed of a backrest, a seat frame and its covering layer. The backrest has two layers, wherein the upper end of the inclined back is hinged on the straight back; the seat frame is composed of left and right side panels and a front panel, and one end of the side panel is fixed on the straight On the back, the other end is hinged and fixed to the front plate; a fixing frame including an adjustable oblique back screw is respectively fixed on the inner side of the left and right side plates, and a positioning frame is respectively provided on the left and right side plates and the front plate.

There is a bracket with a chute on the rear end of the slant, and the other end is clamped on the screw on the straight back through the positioning hole on the chute.

The positioning frame includes sleeve plates fixed on the left and right side plates and the front plate and a support plate sleeved therein.

The fixing frame is fixed on the screw through two sets of positioning holes on it, and can also be fixed directly by the screw.

The left and right side plates and the front plate are respectively equipped with hinged frames, which are connected and fixed by inserting a tapered positioning pin therein after being combined, and an extension plate is vertically arranged above the tapered positioning pin.

A vertically upward limiting plate extends from the supporting plate on the positioning plate.

After adopting the above method, the user can adjust the inclination angle of the oblique back according to his needs, so that the user himself feels comfortable. At the same time, because the entire sofa is assembled, it can be disassembled into several separate pieces when it needs to be transported or moved, which is very convenient to carry separately.

Detailed ways:

As shown in the figure, the utility model is mainly composed of a backrest 1, a seat frame 2 and its cladding layer. The backrest 1 has two layers, wherein the upper end of the oblique back 1 is hinged on the straight back 12; Right side board 21,22 and front board 23 are formed, and side board 21,22 one ends are fixed on the straight back 12, and the other end is hingedly fixed with front board 23; The fixing frame 4 of the oblique back screw rod 3, the left and right side plates 21, 22 and the front plate 23 are also respectively provided with a positioning frame 5.

There is a bracket 6 with a sliding groove 61 at the rear end of the oblique back 11 , and the other end is clamped on the screw 121 of the straight back 12 through the positioning hole 611 on the sliding groove 61 .

The positioning frame 5 includes a cover plate 51 fixed on the left and right side plates 21 , 22 and the front plate 23 and a support plate 52 sleeved therein.

The fixing frame 4 is fixed on the screws through two sets of positioning holes 41 thereon, and can also be directly fixed by screws.

Left and right side plates 21,22 and front plate 23 respectively are equipped with articulation frame 7, connect and fix by inserting a tapered positioning pin 8 wherein after the combination, vertically be provided with extension plate 81 above the tapered positioning pin 8.

A vertically upward limiting plate 53 extends from the supporting plate 52 on the positioning frame 5 . During use, whole sofa as shown in Figure 1 and Figure 2, seat cushion part is placed on the seat frame 2, and the positioning frame 5 of left and right side board 21,22 and front plate 23 can make whole seat cushion keep steady, and in On the positioning frame 5 of the left side plate 21 or the right side plate 22, a spacer plate 53 can ensure that the seat cushion can not move back and forth. When the user feels that the angle of the backrest 1 is not particularly comfortable, the user can pick up the seat cushion, and the structure of the entire seat frame 1 can be seen, and the middle part is hollow. As shown in Figure 3, the lower end of the oblique back 11 is free to lean against the screw rod 3 on the fixed frame 4 inside the left and right side plates 21, 22, and the screw rod 3 only needs to be twisted so that it has a direction relative to the fixed frame 4. The forward or backward displacement is sufficient, and the tilt angle of the oblique back 11 will change to achieve the purpose of adjustment. If the embodiment shown in Fig. 2 is adopted, it can be seen that, as shown in Fig. 4, the oblique back 11 is supported by a bracket 6 with a chute 61, and there are several positioning holes 611 with different positions in the chute 61, and the The screws 121 fixed on the left and right side plates 21, 22 are passed through the chute 61 of the bracket 6, and then snapped into different positioning holes 611 in the chute 61 to make the oblique back 11 have different inclinations. the goal of. Both methods are very simple and can realize the function of adjusting the oblique back. Simultaneously, as can be seen from Fig. 3, there are two sets of positioning holes 41 connected on the fixed frame 4. When installing, enter the screw through the large hole, and then press down the fixed frame 4 so that the screw snaps into the small hole. In this way, there is no need to temporarily use screws to fix the side plate during installation, and it is very convenient to remove and install.

When the utility model needs to be moved, the whole sofa can be dismantled into blocks. First, the positioning pin 8 connecting the left and right side panels 21, 22 and the front panel 23 can be taken out from the hinged frame 7, so that the front panel 23 can be taken off, and then the left and right side panels 21, 22 rear ends are fixed on the Screw 121 on the straight back 12 is taken off, and then left and right side plates 21,22 also can be taken off. The support plate 52 can also be directly taken out from the cover plate 51 and transported separately.

Because there is a vertical extension plate 81 above the positioning pin 8, there is a right angle part on it, when placing, can guarantee the vertical placement of left and right side plates 21,22 and front plate 23.
