Description
Technical field
The present invention relates to a kind of hinge arrangements applied at the folding devices such as folding seat, chair for fishing.
Background technology
In fields such as existing some folding class furniture, devices, the hinge arrangement at folding is various informative, some hinge knots
Structure has self-locating function, that is, is maintained at a certain state of folding, some hinge arrangements do not have positioning function then, pass through other
Class formation is assisted to realize positioning.Wherein there is a kind of hinge arrangement, can unidirectionally realize folding, reversely then there is positioning support function.
By taking chair for fishing as an example, the chair back and seat should realize forward folded (being contacted above the front of the chair back and seat), realize again
Reverse folded (reverse side of the back side of the chair back and seat folds), and the chair back is by reverse side folded state when being rotated in the forward direction, hinge is not
With positioning function, but when intermediate any state is wanted to reversely rotate, then positioning function is needed, the chair back is maintained at any
State, until rotating in the forward direction to during the folding of front, lock-out state is released from, and is reversely rotated to reverse side folded state, hinge
State is switched again.
It is disadvantageous in that existing for above structure, the stroke of the positioning states variation of hinge is long, adjusting back angle
Do not adjust in place once, to undergo a forward folded and it is reverse folded after could realize angular adjustment, convenience again
Poor, the experience sense of user is poor.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1 and Figure 2, a kind of hinge arrangement of the present embodiment, including two pin-joint pieces 2 20 and a pin-joint piece one
10, wherein pin-joint piece 1 is located in the gap between two pin-joint pieces 2 20.Pin-joint piece 1 passes through hinge with pin-joint piece 2 20
40 rotary moveable of spindle connects.Protection cap 30 is equipped with two sides of the pin-joint piece 2 20 far from pin-joint piece 1.Wherein
One end of pin-joint piece 1 is connecting portion 1, and one end of pin-joint piece 2 20 is connecting portion 2 21.
As shown in Figure 3, Figure 4, it is set on the pin-joint piece 1 of the present embodiment there are one profiled holes 12, the profiled holes 12 are interior to be installed
There are one block 50 and an elastic pieces 60.Wherein in profiled holes 12 there is the position 1 for accommodating 50 one end of block and use
In accommodating the position 2 14 of the block other end and position 3 15, have wherein between position 2 14 and position 3 15 there are one protrusion,
Block can be converted in the section of the section and position one of position one and position two with position three.
Above-mentioned profiled holes 12 also have elastic piece installation site 17, as shown in fig. 6, one end of elastic piece 60 is curved portion
62, elastic piece installation position 17 is installed on, the other end is abutment end 61, is resisted against stop-surface shown in fig. 5.
As shown in fig. 7, being set on the pin-joint piece 2 20 of the present embodiment, there are one the arc groove 25 around hinged center, the arcs
The major diameter arcwall face of slot 25 includes ratchet segment 26 and smooth section 28, and the above-mentioned one end of ratchet segment 26 far from smooth section 28 is equipped with one
A transposition protrusion 27, the transposition protrusion are used to the position of block switching to position one and position by the section of position one and position two
Put three section.
It should be noted that in the present embodiment, set that there are one transposition elasticity knots in ratchet segment 26 and 28 junction of smooth section
Structure 24, the transposition elastic construction 24 have cantilever end, can be spring leaf, preferably torsional spring.Using torsional spring in the present embodiment
Form, on pin-joint piece 2 20 be equipped with torsional spring mounting post 40 and fixed jack 22, the torsion spring set be set on in mounting post, torsional spring
One end be inserted into fixed jack in, the other end of torsional spring is extended in the region of arc groove.
In the present embodiment, when the block is between position one and position two, block is in meshing state with ratchet segment；
When the block is between position one and position three, block is in disengaged position with ratchet segment.
With reference to Fig. 8-Figure 19, illustrate the operation principle of the present embodiment hinge arrangement：
As shown in Figure 18,19, block is in meshing state between position one and position two with ratchet segment at this time, hinge
Contact pin one relative to pin-joint piece two can only single direction rotation, i.e. block can only move to the direction of transposition protrusion, and cannot be to smooth
Duan Yidong.At this point, pin-joint piece one and pin-joint piece two can unidirectionally adjust the angle between the block position of engagement and transposition protrusion.
As the direction of block to transposition protrusion is moved, when the position for being moved to Fig. 8, Fig. 9, block connects with transposition protrusion
It touches.Continue to rotate pin-joint piece one, then under the raised role that replaces, block is switched to position by the section of position one and position two
One with the section of position three, state at this time is as shown in Figure 10, Figure 11.Block will not be engaged with ratchet segment at this time, can be without hindrance
It is moved in the case of gear to smooth section.When the state for being moved to Figure 14, Figure 15, block is contacted with transposition elastic construction, is being changed
Under the active force of position elastic construction, block is switched to the section of position one and position two by the section of position one and position three, i.e.,
Figure 16, the state shown in 17.At this point, block can both be moved to the direction of transposition protrusion, engaged with ratchet segment realization；It can also
It is moved to the direction of smooth section, realizes and fold, folded state is as shown in Figure 12,13.
In short, the foregoing is merely illustrative of the preferred embodiments of the present invention, it is not intended to limit the invention, it is all in the present invention
Spirit and principle within all any modification, equivalent and improvement made etc., should be included in protection scope of the present invention it
It is interior.
