Description
- The present invention relates generally to a chair with a tiltable and lockable seat cushion according to the preamble of
patent claim 1. - For chairs it is known to arrange the seat cushion tiltable in all directions. Such tiltable seat cushions are for example useable on chairs comprising a centrally placed support leg, such as regular office chairs, stools or so called saddle chairs. A tiltable seat cushion provides a correct seating position for the user, because it adapts to the motions of the user. A certain instability in the seat cushion also activates certain muscles of the user, which may contribute to an increased muscle strength and decreased ache in the back and neck.
- In patent application
WO1996024274 it is for example disclosed a stool where the seat cushion is attached to a support leg comprising a semi-spherical foot resting on the ground. The seat and support leg pendulate around the ground contact surface of the support leg. - In
US6209958 another solution is disclosed where the seat cushion rests on a spherical joint arranged in the top part of the support leg, which make a pendulating motion of the seat cushion possible in all directions. The tilting motion inertia is determined by an elastomeric spring arranged concentrically around the support leg. The seat cushion is also lockable in all positions by pressing the elastomeric spring towards the spherical joint. - During certain circumstances it may be desirable to be able to lock the seating cushion in a basic position where the main seat surface is horizontal.
- An object of the present invention is to provide a chair which makes a pendulating seat cushion motion in all directions possible and which is easy to maneuver and lock in a basic position.
- The above mentioned object is according to the invention met by a chair according to the characterizing part of
patent claim 1. The inventive chair comprises a seat cushion and an essentially centrally below the seat cushion arranged support leg. It also comprises a joint comprising a first joint part fixedly connected to the seat cushion and a second joint part fixedly connected to the support leg and a spring arranged concentrically around the support leg , acting between the seat cushion and a, in the support leg attached, spring support. The spring is adapted to straighten the seat cushion up to an essentially horizontal basic position and to provide a counter force to the tilting. The invention is characterized in that the first joint part comprises a through-going locating hole in which a pin is moveably arranged, where the pin has a first end which is arranged to be vertically moved into a locking hole arranged essentially concentrically with the center axle of the support leg to lock the seat cushion in an essentially horizontal basic position. - When using this construction the chair may easily be locked in an essentially horizontal basic position. Since the pin rotates with the first joint part when it is not in the locked position, the tilting of the seat cushion is not prevented. Additionally, no sitting forces act directly on the pin. Instead they are absorbed in the spherical joint. This makes it possible to lock the position of the chair also when a person is seated on the chair.
- The invention is now described, by way of example, with reference to the accompanying drawings, in which:
-
- Fig. 1
- shows a chair with a tiltable seating cushion
- Fig. 2
- shows a cut view of the inventive chair comprising a locking pin.
- Fig. 3a-c
- shows locking pin in three different locked positions.
- Fig. 4
- shows an alternative embodiment of the locking pin.
- In the following, a detailed description of invention is disclosed.
-
Fig. 1 shows achair 1 comprising aseat cushion 2 and an essentially centrally below theseat cushion 2 arrangedsupport leg 3. Aspring 4 is arranged essentially concentrically around thesupport leg 3. Thespring 4 rests in its lower end on aspring support 5 and acts in its upper end on asupport plate 6 which theseat cushion 2 is firmly attached to. The spring is adapted to straighten theseat cushion 2 up to a basic position, which means an essentially horizontal position on thesupport plate 6 when no one uses the chair, and to provide a counter force to the tilting when a person is seated on theseat cushion 2..Thesupport leg 3 of the chair may extend all the way to the ground, but it is also possible that it may be attached to a frame part, resting on the ground, comprising for example one or more, not disclosed, legs, wheels or other support arrangements. - In the support leg it may be arranged a
height adjustment arrangement 13 adapted to adjust the length of the support leg. Preferably, theheight adjustment device 13 is a gas spring or a similar arrangement where the pressure can be adjusted by adjustment of avalve position 14. -
Figure 2 shows a cut view of the chair and itsseat cushion 2. Theseat cushion 2 is attached to thesupport plate 6, which in turn is connected to ajoint 8. Thejoint 8 comprises a firstjoint part 8a fixedly connected to thesupport plate 6 and a secondjoint part 8b fixedly connected to thespring support 5, which in turn is attached to thesupport leg 3. The firstjoint part 8a has a cut spherical shape with a ring shaped convex slidingsurface 8a'. The secondjoint part 8b, which is fixedly connected to thespring support 5, has a cylindrical shape with an essentially horizontally arranged inner ring shaped concave slidingsurface 8b'. Thesliding surfaces 8a', 8b' are arranged to slide against each other. - The first
joint part 8a also comprises a through-going locatinghole 9 in which apin 10 is moveably arranged. Thepin 10 has afirst end 10a, which is adapted to be moved vertically into alocking hole 11 arranged essentially concentrically with the center axle x-x of thesupport leg 3. In order to decrease the stress on the firstjoint part 8a, aguide sleeve 12 is inserted into the locatinghole 9. This guidingsleeve 12 is attached to thesupport plate 6. - The
pin 10 is connected to anadjustment arrangement 7, having the shape of a lever (see alsofig. 1 and3a-c ), by which the vertical position of thepin 10 is adjusted in relation to the locatinghole 9. Thelever 7 is articulatedly connected to thesecond end 10b of the pin and is rotatable around a point z, located between the two ends of thelever 7. This point z may be an attachment attached to thesupport plate 6. By moving thelever 7 upwards and downwards, respectively, the pin is moved in the opposite direction. - The
pin 10 can be locked in at least two positions with one or several spring supportedpegs 15, which interconnect withcavities 16 in thepin 10. - In
figure 3a-c three locked positions of thepin 10 is shown; a first position where thepin 10 is free from thelocking hole 11, a second position where thepin 10 is inserted into the locking hole 11 a first distance s1 and a third position where thepin 10 is inserted into the locking hole 11 a second further distance s2 and is therefore interacting with theheight adjustment device 13. It is also possible to adjust the height of the chair in other ways. Then thepin 10 has only two locked positions; one first position where thepin 10 is free from thelocking hole 11 and a second position where thepin 10 is inserted into thelocking hole 11. -
Figure 4 shows an alternative embodiment of the locking arrangement comprising thepin 10 and thelocking hole 11. I this embodiment thelocking hole 11 has a conical opening which decreases in diameter in a direction away from thepin 10. At the same time thepin 10 has a conicalfirst end 10a which is inserted into the lockinghole 11. By using a conical shape on thehole 11 and thepin 10, the locking of the chair in the upright basic position is facilitated since the conical surfaces guide the pin into the hole - In
figure 4 , theadjustment device 7, by with the vertical position of thepin 10 is adjusted, comprises a through-going hole in which a separatefirst activation part 17 is moveably arranged, which is adapted to act on a one in the pin arranged moveablesecond activation part 18, which in turn actuate theheight adjustment device 13. - The invention is not limited to the described embodiments, but can be freely varied within the scope of the patent claims. The features described in the different embodiments may be combined unless it is directly contradictory.
