Detailed Description

In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and for a person skilled in the art, other drawings and other embodiments can be obtained without inventive effort, and the invention is not limited to this example.

Referring to fig. 1, fig. 2 and fig. 3, a three-person sofa with a side seat capable of lying in a horizontal position according to an embodiment of the present invention includes a sofa main body 1, the sofa comprises a sofa main body 1, a first sofa backrest 2, a second sofa backrest 3 and a third sofa backrest 4 which can be connected to the sofa main body 1, and further comprises a plurality of chair back adjusting devices 5 which are respectively arranged between the sofa main body 1 and the first sofa backrest 2, the sofa main body 1 and the second sofa backrest 3, and the sofa main body 1 and the third sofa backrest 4, wherein each chair back adjusting device 5 comprises a height adjusting mechanism 51 and an angle adjusting mechanism 52, each height adjusting mechanism 51 comprises a connecting support keel 511 which is fixedly arranged on the sofa main body 1, a fixed plug-in shaft 512 which is fixedly arranged on the first sofa backrest 2, the second sofa backrest 3 and the third sofa backrest 4, and further comprises a plurality of plug-in slotted holes 513 which are uniformly distributed on the connecting support keel 511 and used for inserting the fixed plug-in shaft 512. In the present embodiment, although the first, second and third sofa supports 2, 3 and 4 are all connected to one sofa main body 1, in practice, the angle adjustment and the height adjustment of the first, second and third sofa supports 2, 3 and 4 are independent and are not linked to each other, even if the three parts adopt the same structure of the backrest adjusting device 5.

As one of the preferred embodiments, the connecting support keel 511 comprises a first arm 5111 fixed on the sofa body 1 and a second arm 5112 connected and fixed to the first arm 5111 and used for setting the plugging slot 513, wherein the first arm 5111 is fixed on the sofa body 1 in a bolt fixing manner. And the connection between the first arm 5111 and the second arm 5112 is an articulated connection. Thus, after the sofa backrest is initially connected to the second arm 5112 in a manner that the fixed plug shaft 512 and the plug slot 513 are fixedly connected, the overall angle between the sofa backrest and the sofa main body 1 can be initially adjusted by rotating the second arm 5112, which can be understood as a rough adjustment of the opening angle between the sofa main body 1 and the sofa backrest. After the angle adjustment is completed, the limit locking member 5113 may be screwed to the hinge bolt 5114, which enables the first arm 5111 and the second arm 5112 to be hinged to each other, and since one end of the bolt has a relatively thick nut structure, after the limit locking member 5113 is screwed to the hinge bolt 5114, the limit locking member may be combined with the bolt to clamp the first arm 5111 and the second arm 5112, so as to largely limit the second arm 5112 or the first arm 5111 from rotating again around the hinge. The fixed plug shaft 512 can be installed in different plug slots 513, so that the height of the sofa backrest can be adjusted, and the head and neck of people with different heights can be attached to the protruding back cushion of the sofa backrest. Resulting in good quality comfort.

As a supplement to this embodiment, corresponding latch structure may be provided on the two surfaces of the first arm 5111 and the second arm 5112 that contact each other, so as to be engaged and butted after the first arm 5111 and the second arm 5112 are clamped to each other, thereby better restricting the first arm 5111 or the second arm 5112 from rotating again around the hinge.

The angle adjusting mechanism 52 of the chair back adjusting device 5 includes a plurality of axial limiting grooves 521 disposed on the fixed insertion shaft 512, a limiting shaft cap 522 provided thereon with a limiting rib 5221 insertable into the axial limiting groove 521 to cover the fixed insertion shaft 512, and a clamping pin 5222 disposed on the limiting shaft cap 522 for clamping on the connecting support keel 511 after the limiting shaft cap 522 is covered on the fixed insertion shaft 512. In use, the limiting shaft cap 522 is covered on the fixed inserting shaft 512, wherein the limiting edge 5221 on the limiting shaft cap 522 is inserted into the axial limiting groove 521 at a certain angle, the clamping pin 5222 arranged on the limiting shaft cap 522 is partially inserted into two side walls of the inserting groove 513, and the rest part is tightly attached to the edge of the outer wall of the connecting support keel 511. The plurality of clamping pins 5222 are coupled to each other. Thereby limiting the rotation of the sofa backrest around the fixed insertion shaft 512. The structure is convenient for the user to finely adjust the angle between the sofa backrest and the sofa main body 1. Corresponding to precise regulation. The user does not need to move the sofa, and then adjusts the angle by rotating the second support arm 5112, which is more convenient.

The sofa connecting cushion is characterized by further comprising a plurality of sofa connecting cushions 6 which are connected and arranged between the sofa main body 1 and the first sofa backrest 2, between the sofa main body 1 and the second sofa backrest 3 and between the sofa main body 1 and the third sofa backrest 4. Because in the present embodiment, there is a gap between the sofa backrest and the sofa main body 1 when the sofa backrest rotates. Therefore, the sofa connecting pad 6 is used for connecting the sofa main body 1 and the sofa backrest for blocking the gap.

Where not mentioned above, all are applicable to the prior art.

Specific embodiments of the present invention have been described above in detail. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by logical analysis, reasoning or limited experiments in the prior art, which are already known to those skilled in the art, should be within the scope of protection defined by the claims.
