Abstract
The present invention relates to a kind of rotary shaft of furniture piece, live spindle (3) of the furniture piece with a rotatable movement in turnbarrel (2), and live spindle (3) has a radial groove (4), one pin (5) radially stretches into this radial groove (4) from this turnbarrel (2), and radial groove (4) is designed as not being entirely around a circle.
Description
Technical field
The present invention relates to a kind of rotary shaft and the furniture piece with corresponding rotary shaft.
Background technology
It is well known that the turning chair as office chair should be designed to its sitting face relative to the rotatable around of leg.
Such as patent DE 1903637U just disclose a kind of such turning chair.
But people be often reluctant it is seen that, sitting face can be rotated by 360 ° relative to leg, but without any backstop
Device, therefore be just easy to occur to be used for the danger for powering or controlling the electric wire of massage functions in leg winding.
Therefore, some seat designs are into a stop device, and the device is arranged on sitting face bottom side, to overhanging from one
The stop element composition of the bolt gone out and an installation on the rotary shaft.
But present problem is that this stop device is far from rotary shaft, therefore bears very big active force this may
Stop device is caused to be destroyed, it is also possible to cause leg to produce people due to the pulsed load born near stop device
Undesired movement.
Additionally, it is also well known that also have some can not it is fully rotating one circle turning chair because rotary shaft is in rotary course
Displacement in vertical direction is carried out due to the inclined-plane of a counterproductive, so that sitting face is in not weight in the case of by load
Newly return to initial position.But the displacement and self-return in vertical direction, which are not people, to be wanted.
The content of the invention
The task of the present invention is that, although creating a kind of sitting face can rotate, this rotation is restricted, and will not
There is the method for vertical direction displacement.
It is addressed by the rotary shaft of the present invention or the furniture piece with corresponding rotary shaft.
According to the present invention, rotary shaft has a live spindle for carrying radial groove, and a pin is radially from rotation
This groove is probeed into rotaring sleeve, while groove is designed to it is not intactly thus to be manufactured in a straightforward manner around a circle
Go out it is a kind of avoid sitting face intactly revolve turn around, the stop mechanism close to axle.Rotation thus can be on the one hand controlled to be produced
Raw active force, on the other hand do not destroy moulded.
In other words, the groove not exclusively around a circle is an incomplete annular in the working face of live spindle
Groove.Do not have the stop mechanism of reeded position or remaining flange (the namely both ends of groove) as the pin for probeing into groove.
Can non-fully be furnished with the stop device of damping around the both ends of the groove of a circle.Thus the backstop of pin is acted
Damping, it can be comfortable on the user of furniture piece, and can avoids surfacing from being damaged.
Playing the stop device of cushioning effect can be made up of elastomer plug-in unit.
The support the inside that these elastomer plug-in units may be inserted between the both ends of groove, connect both ends, from
And become an entirety and keep clamped condition.Then, these elastomer plug-in units are substantially in double-T.
In addition, the plug-in unit for reducing frictional force is designed between turnbarrel and live spindle.
The groove non-fully around a circle in live spindle is preferably what milling formed.
Brief description of the drawings
The side view of Fig. 1 rotating shaft assemblies；
Fig. 2 Fig. 1 Section A-A view；
The side view of live spindle shown in Fig. 3 Fig. 1；
Side view of the live spindle from another position shown in Fig. 4 Fig. 1.
Embodiment
Following explanation is carried out to a preferred embodiment by means of diagram.
A rotating shaft assembly as the overall couch with 1 mark, and this sofa are illustrated in these figures
Chair carries a rotatable live spindle 3 in turnbarrel 2.Live spindle 3 has a radial groove 4, an edge of pin 5
Radial direction stretches into this groove from turnbarrel 2.
Groove 4 not exclusively around a circle is one incomplete in the working face of live spindle 3 " annular groove ".No
The position of groove or remaining flange 6 form both ends 7A, 7B of groove (referring to Fig. 3 and 4), and are used as probeing into groove
The stop mechanism of pin 5；Pin 5 can be bolt arrangement.
Groove 4 not exclusively around a circle has the stop device that cushioning effect is played in both ends 7A, 7B, and its form is to set
Put elastomer plug-in unit 8 here.
Rubbed in addition, being designed with the upper and lower part of turnbarrel 2 and reduction being played between turnbarrel and live spindle
Wipe the plug-in unit 9,10 of power effect.
The plug-in unit 9 on top and a snap ring 11 in the downside of live spindle 3 make live spindle 3 be maintained in turnbarrel 2.
