Definitions
- the invention relates to a piece of seating furniture, in particular an actively dynamic piece of seating furniture according to claim 1.
- the invention relates in particular to an actively dynamic piece of seating furniture with an improved spring strut.
- Various pieces of seating furniture are known in the prior art, which are designed in such a way that the body sits in an anatomically most comfortable position thanks to appropriately designed seat surfaces and backrests.
- Such seating furniture is often felt to be pleasant and comfortable, it distinct disadvantages.
- Sitting on such seating furniture is passive sitting, ie the muscles in the back are subjected to little or hardly any stress and the intervertebral discs are statically subjected to pressure. As a result, wear and tear in the intervertebral disc, degeneration of the back muscles and damage to health as well as pain can occur.
- the foot portion consists of an open ring which is attached to the leg portion by a radially extending traverse such that the leg portion is held substantially in the predetermined position, typically at the center of the slotted ring.
- the stool is designed so that during a pendulum movement, which is caused by the rubber joint installed between the leg part and the radial traverse, a supporting movement takes place at the same time via a rubber buffer on the floor.
- the prior art rocking stool In order to enable an up and down oscillation, which is useful for the dynamic loading of the spine, the prior art rocking stool also has a spring in or on the leg part, such as a spiral spring.
- DE-GM 731114 describes an active dynamic seat device with a seat part which is connected to a support shaft via a first tilting joint, the support shaft in turn being articulated by means of a second tilting joint on the foot part of the seat device.
- Each tilting joint preferably consists of a cap formed at the end of the support shaft, which is guided in a hollow cylinder and acted upon by a helical spring arranged in the hollow cylinder.
- the object of the invention is therefore to overcome the known disadvantages of pendulum stools and pendulum chairs and to create an improved concept for the spring strut. This object is achieved by the combination of features according to claim 1 solved.
- a spring strut for a pendulum chair comprising a central cylindrical center shaft which is axially movably mounted on a number of guide elements in a shaft cage which can be accommodated in a cylindrical securing sleeve having an inner jacket, with the guide elements each having a spring body, on which resilient retaining arms are provided, each with a clamping contour, as well as having a roller rotatably mounted on a shaft, with the shaft cage forming recesses (openings) for resilient mounting of the spring bodies, in each of which a spring body is mounted in a clamping manner and the respective spring body while clamping supported with its clamping contour on a counter-contour on the shaft cage.
- the length, shape and form of the spring arms is selected in such a way that the desired freedom from play is achieved with a specific spring force.
- the clamping contour is designed as a retaining lug protruding from the retaining arm, which preferably forms a contact surface or an undercut on one side.
- the counter-contours provided on the shaft cage for clamping a holding arm are each realized by an edge, in particular an edge pointing inwards toward the center, on the respective recess, namely on the edge that forms the transition from the inner surface of the shaft cage to the side surface of the respective recess forms.
- the recesses for accommodating a spring body each have a substantially rectangular central opening cross section on which two are laterally diametrically opposite ones and adjoin recess areas extending in the circumferential direction for accommodating the holding arms, which in particular have a lower height viewed in the axial direction compared to the height in the area of the central opening cross section.
- the center shaft has at one end a section for attachment to or in a pendulum joint.
- a likewise preferred embodiment of the invention provides that a first set of guide elements (eg four guide elements) is mounted in recesses arranged in the circumferential direction in a first (lower) mounting area (lower mounting plane) of the shaft cage.
- a first set of guide elements eg four guide elements
- a second set of guide elements (e.g. likewise four guide elements) is mounted at a distance from this in the axial direction in an upper mounting area in further recesses each arranged in the circumferential direction. This results in two radially circumferential bearing sections for the center shaft, which are spaced apart from one another in the axial direction and thus contribute to a backlash-free and low-noise mounting of the center shaft.
- two holding arms on diametrically opposite sides of the spring body are each connected in one piece to the spring body via a curved section and these extend radially outwards when the spring body is in the assembled state.
- Another aspect of the present invention relates to a pendulum chair with a seat part and a foot part on which a pendulum joint is arranged, and a spring strut equipped with a coil spring, which is designed with the features as described above, the spring strut having one end on the pendulum joint is attached.
- a likewise further aspect of the present invention relates not only to the spring strut but also to the method for mounting such a spring strut at least the following steps: a. Assembling the several guide elements from the outside through the openings or the recesses of the shaft cage, so that the rollers of the guide elements are each aligned towards the intended position of the center shaft and clamping locking of the guide elements (30) with their holding arms (32) on the counter-contour on the shaft cage (20). The central shaft is then preferably pushed in. In particular, due to this clever design of the shaft cage, the guide elements remain in their intended clamping position even without the central shaft.
- FIG. 1 is a perspective view of a guide element according to the invention in an unassembled configuration
- FIG. 2 shows a perspective view of the guide element according to the invention according to FIG. 1 in the assembled position
- FIG. 3 is a sectional view of a guide element according to the invention in an unassembled configuration
- FIG. 4 shows a sectional view of a guide element according to the invention in the assembled situation
- 5 is a rear perspective view of the present invention guide element from Fig. 2;
- FIG. 6 shows a side view of a spring strut according to the invention
- FIG. 7 shows a sectional view along the section plane AA through FIG. 6
- FIG. 8 shows a sectional view through the spring strut according to FIG. 6;
- FIG. 9 shows a sectional view along the section plane BB through FIG. 6;
- FIG. 10 shows an overview of the parts of the spring strut according to the invention in a pre-assembly position; 11 shows a sectional view through the section plane AA of FIG. 10 to show the assembly of the guide elements.
- the guide elements 30 are Darge provides first.
- the guide elements 30 each have a spring body 31 on which two resilient retaining arms 32 are provided. Furthermore, a shaft 33 is attached to the spring body 31, on which a rotatably mounted roller 34 is mounted.
- the two resilient holding arms 32 have a section 32a which, in the mounted state, as shown in FIG. 9, extends through the openings in the shaft cage 20.
- the retaining arms have the clamping contour K indicated in FIG. 4. This clamping contour K forms at least the outwardly protruding lug 37. With this lug 37, the holding arm 32 clamps in the mounted state on the inner edge 24 of the respective recess 21, as can be seen clearly in the synopsis of FIG. 11 (before assembly) and FIG. 9 (after assembly).
- FIG. 5 shows a perspective rear view of the guide elements 30 to show the section 35.
- the section 35 of the spring body 31 is curved “convexly” for this purpose, specifically as a part-cylindrical surface, with a radius of curvature that corresponds to the radius of the cylindrical Corresponds to the shaft cage, so that the spring body 31 is arranged within the envelope of the outer jacket of the shaft cage 20 in the assembled state, as can be seen in FIG. 6 shows a side view of a spring strut 1.
- the spring strut 1 comprises a central, cylindrical center shaft 10 which is mounted in a shaft cage 20 on the upper and lower guide elements 30 so that it can move axially.
- Four guide elements 30 are arranged in each assembly level M1, M2.
- the securing sleeve 40 is arranged around the shaft cage 20 and accommodates the shaft cage 20 with the guide elements 30 . In the mounted state, the guide elements 30 are therefore all in contact with the cylindrical inner casing 41 of the securing sleeve 40 .
- a second set is four Guide elements 30 mounted in the upper mounting area M1 of the shaft cage 20 in the receptacles 21 provided there.
- the receptacles or recesses 21 are at least partially formed as openings, so that the resilient retaining arms 32 can extend through the openings at least with a section 32a (see the shape in FIG. 10).
- the implementation of the invention is not limited to the preferred exemplary embodiments specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different designs.
