Example Embodiment

[0065] Example 1

[0066] Such as Figure 1~8 As shown, the base plate 1 of the adjustable forward tilting swivel chair base is a one-piece cast iron stamping molding, and the whole is horizontally arranged. A lifting wrench 7 and a tilt adjustable wrench 8 are respectively arranged on both sides of the chassis base 1.

[0067] The middle plate 2 is fitted on the top of the chassis base 1 through the tilt rotation axis Q; the tilt rotation axis Q is hinged to the middle plate vertical wall 2.b of the middle plate 2 and the base plate vertical wall 1.b of the chassis base 1. The forward tilting plate 3 is fitted above the intermediate plate 2 through the forward tilting middle rotating shaft P'. The forward inclination pivot axis P'is hinged to the forward inclination board vertical wall 3.b of the forward inclination board 3 and the intermediate board vertical wall 2.b of the intermediate board 2.

[0068] The front end of the chassis base 1 is laterally fitted with a tilt shaft Q....

[0086] Example 2

[0087] Such as Figure 9-22 As shown, the base plate 1 of the adjustable forward tilting swivel chair base is a cast iron stamped and formed one-piece, and the whole is horizontally arranged. The main body is the central base plate 1.a, and the base plate 1.a is provided on both sides of the base plate 1.a. A base plate standing wall 1.b.

[0088] The middle plate 2 is fitted on the top of the chassis base 1 through the tilt rotation axis Q; the tilt rotation axis Q is hinged to the middle plate vertical wall 2.b of the middle plate 2 and the base plate vertical wall 1.b of the chassis base 1. The forward tilting plate 3 is fitted on the middle plate 2 through the forward tilting bottom rotating shaft P. The forward tilting bottom rotation axis P is hinged to the forward tilting plate vertical wall 3. b of the forward tilting plate 3 and the base plate vertical wall 1. b of the chassis base 1.

[0089] Each base plate vertical wall 1.b is sequentially provided w...

[0107] Example 3

[0108] This example Figure 23 As shown, it is generally the same as in Example 2, except that:

[0109] The forward tilting plate 3 is fitted above the intermediate plate 2 through the forward tilting middle rotating shaft P'. The forward inclination pivot axis P'is hinged to the forward inclination board vertical wall 3.b of the forward inclination board 3 and the intermediate board vertical wall 2.b of the intermediate board 2.

[0110] The middle plate 2 is provided with a forward-inclined intermediate shaft hole 2.6.3' for installing the forward-inclined intermediate shaft P’. The forward tilt pivot axis P'passes through the base plate forward pivot axis hole 1.b.3' of the base plate vertical wall 1.b of the base plate 1, and the forward tilt plate 3 and the intermediate plate 2 are hinged so that the forward tilt plate 3 can move forward. The tilt axis P'is the axis of rotation.

[0111] The design in other places is the same, adjust the distance between the...

Abstract

The invention discloses a swivel chair base capable of leaning forward in an adjustable mode. A swivel chair supporting rod is installed through a swivel chair rod hole in a subbase, an intermediate plate is installed above the subbase in a matched mode through a leaning rotation shaft, and the leaning rotation shaft is hinged to the vertical wall of the intermediate plate and the vertical wall of the subbase; a forward leaning plate is installed above the intermediate plate in a matched mode through a forward leaning bottom rotation shaft or forward leaning middle rotation shaft, and the forward leaning bottom rotation shaft is hinged to the vertical wall of the forward leaning plate and the vertical wall of the subbase; the forward leaning middle rotation shaft is hinged to the vertical wall of the forward leaning plate and the vertical wall of the intermediate plate. The swivel chair base and a chair back can lean forward simultaneously in a matched mode so as to fit the back, waist and whole pelvis of people who sit on a chair and better accord with human engineering; people feel more comfortable. The design can improve the practicality of the product, meet the requirements of consumers, and facilitate market expansion and product upgrading for enterprises.

Description

technical field [0001] The invention relates to the technical field of swivel chairs in the furniture industry, in particular to a swivel chair base with adjustable forward tilt. Background technique [0002] A swivel chair is a common piece of furniture. Existing swivel chairs can generally rotate horizontally and adjust height up and down. There are also some swivel chairs that can adjust the recline of the chair back. In particular, some swivel chairs can also ensure the tilting rocking motion of the chair back to match the posture of the human body, or to match the position of the center of gravity of different sitting postures. However, the structures and effects of various current swivel chairs are relatively single, and do not simultaneously satisfy multiple functions and human needs. [0003] For example, the design scheme of the Xiaoyao structure with the patent number DE202011002235U1 is to ensure that the seat plate can move forward and backward within a certai...
