Examples
Referring to fig. 1-3, the present invention provides a hinge 1, the hinge 1 includes a first mounting plate 11, a second mounting plate 12, a first supporting rod 13 and a second supporting rod 14. The first mounting plate 11 is used for installing the sofa cushion, the second mounting plate 12 is used for installing the sofa base, and the first mounting plate 11 is parallel to the second mounting plate 12. The first mounting plate 11 and the second mounting plate 12 are connected through a first supporting rod 13 and a second supporting rod 14, wherein one end of the first supporting rod 13 is rotatably connected with the right side of the first mounting plate 11, and the other end of the first supporting rod 13 is rotatably connected with the right side of the second mounting plate 12. One end of the second supporting rod 14 is rotatably connected with the left side of the first mounting plate 11, and the other end is rotatably connected with the left side of the second mounting plate 12. The two struts connect with the four connecting points of the two mounting plates to form a parallelogram so that the first mounting plate 11 can rotate relative to the second mounting plate 12. And the second strut 14 is bent toward the first strut 13 to form a bent portion 141, and the bent portion 141 is used for storing the articles. As shown in fig. 3, when the hinge 1 is rotated, if the second bar 14 is replaced by the straight bar 18, the storage cavity provided by the straight bar 18 is the storage cavity a17 a. And if be using the utility model provides a second branch 14 of buckling because second branch 14 buckles, kink 141 has formed storing chamber B17B, promptly the utility model provides a storing chamber size is storing chamber A17a and storing chamber B17B's the total volume in addition, and then uses the utility model provides a volume in the storing chamber of hinge 1's sofa increases.
Specifically, the first mounting plate 11 includes a mounting portion 111 and a connecting portion 112, the mounting portion 111 is disposed horizontally and is used for mounting a sofa cushion, and the connecting portion 112 is perpendicular to the mounting portion 111 and provides a mounting position for the first support rod 13 and the second support rod 14. To facilitate the installation of the seat cushion, at least two installation holes are usually provided on the installation portion 111, so as to fix the seat cushion and the installation portion 111 together by screws.
It will be appreciated that at least two mounting holes are also typically provided in the second mounting plate 12 to facilitate the fastening of the seat cushion to the mounting portion 111 by screws.
Referring to fig. 3 to 5, fig. 5 shows an initial state in which the hinge 1 is mounted on the sofa, and the first mounting plate 11 is provided with a first coupling hole 113 and the second mounting plate 12 is provided with a second coupling hole 121. As shown by the dotted line in fig. 5, if the straight rod 18 is connected to the first connection hole 113 and the second connection hole 121, the straight rod 18 is not bent, and the straight rod 18 encroaches on the storage space defined by the dotted line and the second support rod 14, so that the storage space of the sofa in the initial state is smaller.
The sofa is shown in the unfolded state (the rest of the storage space on the right side of the storage chamber a17a is not shown) in fig. 3 or 4, and the sofa is rotated by the hinge 1 to be extended into a temporary bed. Likewise, the straight bar 18 is illustrated in phantom, and when the straight bar 18 is used, the volume of the storage compartment B17B is encroached upon by the straight bar 18 as compared to the second bar 14.
Referring to fig. 4-5, fig. 5 is a structural diagram of the initial state of the hinge 1, that is, the structural diagram of the hinge 1 installed in the sofa and the sofa cushion in the normal state. At this time, the included angle between the second strut 14 and the second mounting plate 12 is the largest, and the bent portion 141 of the second strut 14 abuts against the mounting portion 111 of the first mounting plate 11. At this time, due to the support of the bent portion 141, when the user sits on the sofa cushion, the position of the first mounting portion 111 is stable and does not change.
Fig. 4 shows a schematic view of the structure of the sofa converted into a temporary bed by the rotation of the hinge 1. At this time, the bent portion 141 of the second bar 14 makes the storage cavity have a larger space, so that more articles can be stored. Meanwhile, the first supporting rod 13 is bent toward the second supporting rod 14, and after the first supporting rod 13 is rotated by a certain angle (i.e., when the included angle between the first supporting rod 13 and the second mounting plate 12 is the largest), the bent portion of the first supporting rod 13 abuts against the mounting portion 111 of the first mounting plate 11. The cushion of sofa stretches out this moment, if use straight-bar 18, then only rely on sofa cushion itself to support it and maintain current position this moment, the user can make the cushion unstable at long-term user. In the present application, the first support rod 13 abuts against the first mounting plate 11, and the support cushion is maintained at a fixed position.
Because the user is required to rotate the cushion and then drive the hinge 1 to rotate, the cushion is difficult to push to rotate due to small strength during rotation. As shown in fig. 6, a plurality of through holes 131 are provided on both the first support rod 13 and the second support rod 14, and a connection block 15 is installed in one of the through holes 131 of the first support rod 13, and a connection block 15 is also installed in one of the through holes 131 of the second support rod 14, and the two connection blocks 15 are arranged oppositely. An elastic piece 16 is arranged between the two connecting blocks 15, and two ends of the elastic piece 16 are respectively connected with the two connecting blocks 15. In the initial state (the state when the sofa is deformed into a bed), the elastic member 16 is in a stretching state, and when the sofa cushion needs to be rotated, the elastic member 16 has a tendency to contract, so that the sofa cushion is rotated more easily. After the sofa is transformed into a temporary bed, the elastic member 16 is also in a stretching state, and the sofa cushion is also more labor-saving because the elastic member 16 has a tendency to shrink.
It will be appreciated that the resilient member 16 is typically a spring,
fig. 7 shows a functional rack, which is composed of two hinges 1 and a connecting rod. The two ends of the connecting rod are respectively fixedly connected with the two hinges 1. In particular, in order to enable the two hinges 1 to move synchronously, the two ends of the connecting rod are fixedly connected in the same position opposite to the first strut 13 or the second strut 14. When the first arm 13 or the second arm 14 of one hinge 1 is rotated, the other hinge 1, which is oppositely arranged, starts to rotate simultaneously due to the connection of the connecting rod 2.
Further, the connecting rod is the telescopic link, after two hinge 1 connect connecting rod 2, in order to make the function frame can be applicable to the sofa cushion of different length, can adjust the distance between two hinge 1 through the telescopic link for the function frame can be applicable to the sofa of multiple specification.
It will be appreciated that the length of the telescopic rod can be deadlocked after determination to ensure the stability of the hinge 1.
The utility model also discloses a sofa, this sofa includes cushion, base and foretell function frame. The upper part of the functional frame is fixedly connected with the sofa cushion, and the lower part of the functional frame is fixedly connected with the base. When the seat cushion is far away from the upper side of the base, as can be known by combining fig. 5, the second support rod is abutted against the first mounting plate 11, and the surface of the seat cushion of the sofa is more stable through the support of the hinge 1. As can be seen from fig. 4, the first frame bar abuts against the first mounting plate 11, and the sofa cushion surface is supported by the hinge 1 more stably.
It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
