Specific implementation mode
By the description got off will use such as "horizontal", " vertical ", " transverse direction ", " front and back ", " upper and lower ", " top ", " under
Portion ", "inner", the term of "outside" or the like.These terms be usually directed to it is as shown in the figures and with the normal use of chair
Associated view and orientation.The term is only used for reader conveniently and is not intended to be restrictive.
Fig. 1 shows that the embodiment of the incline controller on the tilt component 4 on office chair, the office chair have by column
The seat 3 of 2 supports.Column 2 is connected to pedestal (not shown) in a manner known in the art.Advantageously, which can also wrap
Include backrest (not shown).
Tilt component is type commonly known in the art, has the bottom housing part 5 for being connected to column 2 and is connected to seat
3 upper housing portion 6.Housing section 5,6 is pivotally connected to via hole 8 by axis (reference numeral 28 in Fig. 4 a).Spring (does not show
Go out) it is arranged between housing section, which is used for damping pivoting action, and is constructed such that neutrality (balance) state of spring
Corresponding to more or less horizontal seat position.This spring structure is commonly known in the art, and therefore need not be
This is described further.
Referring further to Fig. 2,3a, 3b, 4a-c and 5a, the diagram embodiment for the incline controller invented includes main body 12,
Main body 12 is connected to upper housing portion 6 via footing mechanism (footing fundation) 9 and bolt 10.In the embodiment of diagram
In, there is main body 12 generally cylindrical shape to move towards axial hole with the flute profile for being configured to slidably receive locking bolt 16
31.Bolt 16 has bar portion 17, front end 20 and intermediate shoulders 19.The hole is in both ends open, and inner end 33 (Fig. 3 a)
It is shaped as and accommodates bar portion but do not accommodate front end.Therefore bar portion 17 can partly slide through inner end 33 and upper housing portion 6
In guide opening 30.
Interior disc spring 27 is disposed about bar portion 17 and coaxial with bar portion 17.In assembled state, in the hole of main body 12,
Inner spring 27 is configured to abutment shoulder portion 19 at one end, and inner wall part 32 is abutted at the other end.
Control handle 7 is slidably disposed on the outside of main body 12.Knob 7 has inner cavity and is configured for containing main body
The annular groove 29 of 12 part.In assembled state, outer helical spring 26 is arranged in the inner cavity of knob, and abuts at one end
The front end 20 of bolt, and the bottom of knob chamber 34 is abutted at the other end.
Knob 7 includes two grooves 14 (diametrically opposed to each other), and each groove is configured for and pair in main body 12
Cam 24 and pawl 23 is answered to cooperate.When knob 7 is assembled into main body 12, pawl 23 is used as past in main body for knob
The outer limiting device moved again.Fig. 5 a show the knob in the outer fix：Knob lantern ring 25 abuts against main body pawl 23
On.Cam 24 is connected to main body 12 (referring to Fig. 4 c) via strap 21 so that cam can be elastically inwards bent.Therefore,
When position shown in knob 7 is pushed to Fig. 5 b, cam is depressed by lantern ring 5 immediately.Cam is then used for knob being maintained at
In position shown in Fig. 5 b.When user is pulled back on knob knob will be made to be in position shown in Fig. 5 a, set is circumferential
Buckle (snap) is returned on elastic cam.
Therefore control handle 7 and locking bolt 16 are not connected directly, but control handle 7 is via middle elastic members (bullet
Spring 26,27) control locking bolt 16 movement.
Bottom housing part 5 includes multiple receiving portions 18, and the multiple receiving portion 18 is arranged at regular spacings into corresponding to arch
The bow-shaped structural of banking motion M.Each receiving portion 18 is configured for containing a part for locking bolt bar portion 17.Therefore, lead to
It crosses and locking bolt 16 is inserted into one in receiving portion 18 (such as shown in Figure 5 c), upper casing can be interlocked with multiple inclination angles
Body portion 6 and bottom housing part 5.
Fig. 5 a and Fig. 6 a illustrate the incline controller in " not actuated and unlocked " state：Knob 7 is drawn back into
Lantern ring 25 abuts the position of pawl 23, and locking bolt 16 is also withdrawn into main body 12.Bolt does not engage any receiving portion
18, and bottom housing part 5 and upper housing portion 6 are free to translate relative to each other (that is, being pivoted around axis 28, as shown in fig. 4 a).
In this state of incline controller, outer spring 26 and inner spring 27 are in equilibrium state.
Fig. 5 b and Fig. 6 b illustrate the incline controller in " starting and unlocked " state.Bottom housing part 5 and upper casing
Body portion 6 has been moved relative to each other so that locking bolt 16 is not aligned with any receiving portion.Knob 7 be pushed inwardly to
Lantern ring 25 has been moved across the position of cam 24, to compress outer spring 26 and therefore push locking bolt 16 to bottom housing part
5, and the free end of bar portion 17 adjacent bottom housing part 5 between adjacent receiving portion 18.The device is consequently set as locking.
In (being illustrated in Fig. 5 b and 6b) state, housing section 5,6 can be moved slightly relative to each other, once but bar portion 17 with accommodate
Portion 18 is aligned, then bar portion will be pushed by (outer spring 26 of compression) in described accommodation section, and housing section 5,6 is made to lock relative to each other
It is fixed.The state is shown in Fig. 5 c and 6c.
Fig. 5 c and Fig. 6 c illustrate the incline controller in " not actuated and locking " state：Such as above with reference to Fig. 5 b and
As 6b descriptions, knob 7 has been pushed inwardly, and the front of bar 17 is arranged in receiving portion 18.Housing section 5,6 is therefore
It is locked relative to each other.In the state of incline controller, the state of the spring illustrated in and Fig. 5 b, 6b is compared, outside
Spring 26 slightly stretches (relaxation), and inner spring 27 is compressed.
If user pulls back when housing section 5,6 is located at as in the position shown in Fig. 5 c and 6c on knob 7, then interior bullet
Spring 27 pushes bolt to knob and removes bar portion 17 from receiving portion 18.Housing section 5,6 will be pivoted relative to each other again (that is, such as
Shown in Fig. 5 a and 6a).
Fig. 5 d and Fig. 6 d illustrate the incline controller in " starting and locked " state：A part for bar 17 is still
In receiving portion (as shown in Fig. 5 c and 6c), but housing section 5,6 (e.g., moves him or she in seats by user
On weight) slightly move relative to each other, to make receiving portion 18 clamp and keep bar portion 17.Knob 7 has been pulled outwardly
It is dynamic, and when bar portion is kept in the suitable position of (clamping) in receiving portion (when being in the lock state), inner spring 27 is in
With the same state illustrated in Fig. 5 c and 6c.Compared with the state illustrated in Fig. 5 c and 6c, outer spring 26 is allowed to stretch.Work as rotation
Button has been set to unlock in this way the device, and when the clamping force between receiving portion and bar portion stops, compression
Inner spring 27 will make locking bolt bar 17 remove receiving portion, and therefore housing section 5,6 be allowed to be pivoted relative to each other (such as by scheming
Shown in 5a and 6a).
In use, the incline controller invented is thereby, it is ensured that locking bolt bar 17 is provided to make in the device
Always enter in nearest receiving portion 18 when locking (Fig. 5 b and 6b).The incline controller invented also assures housing section 5,6
It will not be released relative to each other and (be allowed to pivot), except non-user is just seated on the seat and discharges clamping force, such as with reference to Fig. 5 d
As being described with 6d.
It will be obvious to those skilled in the art that a variety of modifications can be carried out to the incline controller invented
And/or addition, but these modifications and/or addition should be maintained in the field of the invention and range.Although for example, reference
Disc spring 26,27 describes the present invention, it is to be understood that, any elastic element may be used.Although it is not shown, but being expected only
Using the embodiment of an elastic element.
Although in addition, describe the present invention with reference to seat leaning device, it is to be understood that, the present disclosure applies equally to
Backrest inclination mechanism.
