Description

Technical Field

[0001] The utility model patent relates to chairs, and in particular to a reclining chair frame. Background Art

[0002] A recliner is a chair with a long backrest that tilts backwards, where people can lie diagonally. There are many types of recliners on the market, which can be divided into fixed recliners and folding recliners according to their structural types. Among them, fixed recliners have a simple structure and are easy to use, and their frames are mostly made of wooden structures.

[0003] like Figure 1 As shown in FIG. 1 , the side bars on the fixed reclining chair frame play an important supporting role in the structural stability of the reclining chair. During use, the pressure exerted by the user on the reclining chair will act on both the seat and the backrest, which will cause a bending moment between the seat side bars 1 and the backrest side bars 2 connected as one, forcing the angle between the two to further expand. Over time, cracks will appear at the connection between the seat side bars 1 and the backrest side bars 2 (such as Figure 1 The chair may even break directly, thus shortening the normal service life of the chair. Summary of the invention

[0004] The utility model provides a reclining chair frame, which improves the structural strength of the connection between the seat side rods and the chair back side rods and reduces the possibility of fracture at the connection between the seat side rods and the chair back side rods.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted is: a reclining chair frame, including a seat frame and a chair frame connected to the rear side of the seat frame and extending from bottom to top and from front to rear, the seat frame including a front frame rod and seat frame side rods extending rearward at both ends of the front frame rod, the chair frame including an upper frame rod and chair frame side rods arranged downward and forward obliquely at both ends of the upper frame rod, the seat frame side rods and the chair frame side rods are butt-jointed at their rod ends and a reinforcing plate is provided at the joint, the joint between the rod ends of the seat frame side rods and the chair frame side rods is located in the middle of the reinforcing plate, and the two ends of the reinforcing plate are respectively extended in the rod length direction of the seat frame side rods and the chair frame side rods.

[0006] Compared with the prior art, the technical effect of the utility model is as follows: by arranging a reinforcing plate at the joint of the rod ends of the seat frame side rods and the chair frame side rods, the two ends of the reinforcing plate are extended from the joint toward the rod length direction of the seat frame side rods and the chair frame side rods respectively, so as to strengthen the structural firmness of the joint between the seat frame side rods and the chair frame side rods, enhance the bending moment resistance of the joint, avoid the fracture of the connection between the seat frame side rods and the chair frame side rods, and ensure the normal service life of the recliner frame.

[0011] The following is combined with Figure 1-4 And related content, the utility model is further described in detail:

[0012] A reclining chair frame comprises a seat frame 10 and a chair frame 20 connected to the rear side of the seat frame 10 and extending from bottom to top and from front to rear, the seat frame 10 comprises a front frame rod 11 and seat frame side rods 12 extending rearward at both ends of the front frame rod 11, the chair frame 20 comprises an upper frame rod 21 and chair frame side rods 22 arranged obliquely downward and forward at both ends of the upper frame rod 21, the seat frame side rods 12 and the chair frame side rods 22 are butted against each other at the rod ends and a reinforcing plate 30 is provided at the butt joint, the butt joint between the seat frame side rods 12 and the chair frame side rods 22 is located in the middle of the reinforcing plate 30, and the two ends of the reinforcing plate 30 are respectively extended in the rod length direction of the seat frame side rods 12 and the chair frame side rods 22.

[0013] In the above scheme, the seat surface for supporting the human body is arranged in the frame area of ​​the seat frame 10 and the chair frame 20. By arranging a reinforcing plate 30 at the joint of the rod ends of the seat frame side rod 12 and the chair frame side rod 22, the two ends of the reinforcing plate 30 extend from the joint to the rod length direction of the seat frame side rod 12 and the chair frame side rod 22 respectively. After the reinforcing plate 30 is fixed to the seat frame side rod 12 and the chair frame side rod 22, the structural firmness of the joint between the seat frame side rod 12 and the chair frame side rod 22 can be strengthened, the bending moment resistance performance of the joint is enhanced, the fracture of the connection between the seat frame side rod 12 and the chair frame side rod 22 is avoided, and the normal service life of the reclining chair frame is ensured.

[0014] As a preferred solution, the rod end sections of the seat frame side rod 12 and the chair frame side rod 22 that extend and connect with each other have a seat frame side rod concave surface 121 and a chair frame side rod concave surface 221 on the same side rod surface, respectively. The seat frame side rod concave surface 121 and the chair frame side rod concave surface 221 form a receiving cavity whose peripheral contour is consistent with the peripheral contour of the reinforcing plate 30 and accommodates the reinforcing plate 30. The recessed depth of the seat frame side rod concave surface 121 and the chair frame side rod concave surface 221 is consistent with the reinforcing plate 30. The receiving cavity formed by the seat frame side rod concave surface 121 and the chair frame side rod concave surface 221 can position the reinforcing plate 30, and the reinforcing plate 30 is built into the receiving cavity. The reinforcing plate 30 is flush with the rod surface at the joint of the seat frame side rod 12 and the chair frame side rod 22, and the periphery of the reinforcing plate 30 is attached to the edge of the seat frame side rod concave surface 121 and the chair frame side rod concave surface 221, so that the appearance is neat, the structural arrangement is reasonable and beautiful.

[0015] It should be noted that the reinforcing plate 30 can be arranged on one of the upper, lower, left and right rod surfaces of the rod end section at the joint between the frame side rod 12 and the chair frame side rod 22, or the reinforcing plate 30 can be arranged on multiple rod surfaces at the same time to improve the structural strength of the joint between the frame side rod 12 and the chair frame side rod 22.

[0016] In order to further improve the bending moment resistance performance of the joint between the seat frame side rod 12 and the chair frame side rod 22 after the reinforcement plate 30 is installed, the left and right reinforcement plates 30 are arranged on the plumb plane and their plate surfaces are opposite to each other. As shown in the figure, compared with the arrangement of the reinforcement plate 30 in which the plate surface is perpendicular to the left and right sides of the seat frame side rod 12 and the chair frame side rod 22, the reinforcement plate 30 has reliable bending strength and is conducive to the connection with the chair leg 50.

[0017] Combination Figure 2 , 3 As shown, the reinforcing plate 30 is detachably connected to the seat frame side rod 12 and the chair frame side rod 22 by bolts, and the bolts are connected to the corresponding bolt holes on the chair legs 50 to connect and fix the reinforcing plate 30 and the chair legs 50. Independent bolts can also be used to separately fix the reinforcing plate 30 and the chair legs 50.
