Abstract

The invention relates to a rotary shaft for a piece of seating furniture, comprising a rotary spindle (3) that is rotatably guided in a rotary sleeve (2). The rotary spindle (3) has a radial slot (4) into which a pin (5) radially protrudes from the rotary sleeve (2) and which does not extend all the way around the spindle.

Description

The rotating shaft of furniture piece

Technical field

The present invention relates to a kind of rotating shaft and the furniture piece with corresponding rotating shaft。

Background technology

It is known that its sitting face should be designed to relative to the rotatable around of leg as the such revolving chair of office chair。Such as patent DE1903637U just discloses a kind of such revolving chair。

But people be often reluctant it is seen that, sitting face relative to leg rotating 360 degrees, but can not have any stop device, is therefore just easy to occur that leg is wound around for powering or controlling the danger of electric wire of massage functions。

Therefore, some seat design becomes to have a stop device, and this device is arranged on sitting face bottom side, outwardly directed bolt and a stop element installed on the rotary shaft by one and forms。

But problem is that this stop device is far from rotating shaft now, therefore bears very big active force。This this may result in stop device and is destroyed, it is also possible to cause that leg produces the undesired movement of people due to the pulsed load that bears near stop device。

In addition, it is known that, also have some cannot fully rotating one circle revolving chair because rotating shaft carries out the displacement in vertical direction due to the inclined-plane of a counterproductive in rotary course, so that sitting face backs within initial position when not by load。But, displacement and self-return in vertical direction are not that people want。

Summary of the invention

The task of the present invention is, can rotate although creating a kind of sitting face, but this rotation is restricted, and the method not havinging vertical direction displacement。

By the rotating shaft set forth in claim 1 or set forth in claim 7, be addressed with the furniture piece of corresponding rotating shaft。

According to the present invention, rotating shaft has a rotation main shaft with radial groove, one pin radially probes into this groove from turnbarrel, simultaneously groove is designed to not be intactly around a circle, thus produce in a straightforward manner a kind of avoid sitting face intactly revolve turn around, close to the stop mechanism of axle。Thus can control to rotate produced active force on the one hand, not destroy moulded on the other hand。

In other words, the groove not exclusively enclosed around is an incomplete cannelure in the work surface rotating main shaft。Do not have reeded position or remaining flange (namely the two ends of the groove) stop mechanism as the pin probeing into groove。

The stop device of damping non-fully can be furnished with around the two ends of the groove of a circle。Thus the backstop action damping to pin, can make the user of furniture piece be comfortable on, be avoided that again surfacing is impaired。

The stop device playing cushioning effect can be made up of elastomer plug-in unit。

These elastomer plug-in units may be inserted into inside the support coupled together between the two ends of groove, by two ends, thus becoming an entirety and keeping clamped condition。Then, these elastomer plug-in units are substantially in the form of double-T。

Additionally, design has the plug-in unit reducing frictional force between turnbarrel and rotation main shaft。

The groove preferably milling non-fully surrounding a circle on rotation main shaft。

Accompanying drawing explanation

The side view of Fig. 1 rotating shaft assembly；

The Section A-A view of Fig. 2 Fig. 1；

The side view of main shaft is rotated shown in Fig. 3 Fig. 1；

The main shaft side view from another position is rotated shown in Fig. 4 Fig. 1。

Detailed description of the invention

By means of diagram, one preferred embodiment is carried out following explanation。

Illustrate a rotating shaft assembly as the overall couch with 1 mark in these figures, and this couch is with a rotatable rotation main shaft 3 in turnbarrel 2。Rotating main shaft 3 and have a radial groove 4, a pin 5 radially stretches into this groove from turnbarrel 2。

Not exclusively the groove 4 around a circle be one in the work surface rotating main shaft 3 incomplete " cannelure "。Do not have reeded position or remaining flange 6 (referring to Fig. 3 and 4) to define two ends 7A, 7B of groove, and be used as to probe into the stop mechanism of the pin 5 of groove；Pin 5 can be bolt arrangement。

Not exclusively having, around the groove 4 of a circle, the stop device playing cushioning effect at two ends 7A, 7B, its form is be arranged on elastomer plug-in unit 8 herein。

Additionally, have at turnbarrel in the design of the upper and lower of turnbarrel 2 and rotate the plug-in unit 9,10 playing reduction frictional force effect between main shaft。

The plug-in unit 9 on top and a snap ring 11 on the downside of rotation main shaft 3 make rotation main shaft 3 be maintained in turnbarrel 2。

Claims

1. the rotating shaft of furniture piece, it is characterized in that, furniture piece is with the rotation main shaft of a rotatable movement in turnbarrel, and rotate main shaft and there is a radial groove, one pin radially stretches into this radial groove from this turnbarrel, and groove is designed as non-fully around a circle。

2. meeting the rotating shaft of claim 1, it is characterized in that, described non-fully around the two ends of the groove of a circle, design has the stop device playing cushioning effect。
