Definitions
- the invention relates to a seat device, in particular stool, with a platform and a seat mounted on the platform by means of a tilting surface, the platform and the seat concave, successive shells are assigned, between which the tilting element is arranged.
- Such a seat device is from the DE 103 11 998 A1 known.
- Such a seat device namely stool, is also from the DE 103 57 162 B4 known.
- a ball as a tilting element between them.
- the seat is thereby displaced and tilted in all directions, so that the entire spine and in particular the lumbar region of the user remains mobilized and is not immobilized, as in otherwise conventional seating devices.
- the user is thereby urged to always take an active, dynamic sitting position, which leads to an invigoration of the corresponding holding muscles and thus postural damage and further consequential damage can be avoided.
- the shells are formed in this prior art such that they have a flat, central area which is surrounded by a curved edge region or inclined edge region. At the transition from the plane central region to the bent or inclined region, a "stopping effect" arises, which is unpleasantly noticeable to the user sitting on the seat surface when the ball reaches this transition region. The seating comfort is impaired.
- the invention is based on the problem, a seat device, in particular stool, of the type mentioned in such a way that the seating comfort and range of motion are increased for the user.
- At least one of the concave shells is formed with a radially decreasing in the radial direction of the shell outwardly decreasing radius, wherein the radii with the same tangential angle merge into one another.
- the middle, central region of the shell is already concave in itself, but with a radius larger than the edge region. This does not create a stop effect at the transition. Rather, the resistance increases only by further tilting and / or moving the seat relative to the platform, which is noticeable to the user in a gentle increase in resistance to further movement. Furthermore, there is a self-centering for the ball, since the already concave design of the central region of the shell results in a defined equilibrium position. It is also important that the radii merge into one another with the same tangential angle. In other words: a convex recess in the shell must be formed continuously differentiable. Otherwise, cracks or edges would be created in the shell, which would also be noticeable in a shock effect for the user.
- the seat assembly thus has a common rotational, sliding and center of gravity directly on the seat plate and allows a soft, differentiated movement of the lumbar spine over the thoracic and cervical spine to the head joint.
- the shell can have two or more different radii viewed radially outwards. For example, a central central region with a large concave radius and the edge region with a smaller radius are formed. The important thing is that the radius in the edge area is not smaller than the radius of the ball, because this would again lead to the stop effect. The radius in the middle area must be correspondingly larger. The same applies if, according to another embodiment of the invention, the shell is formed with a radially outwardly continuously decreasing radius. It is particularly favorable for the comfort, if both shells, so both the shell in the seat and the shell in the platform, as described above are formed, which is of course possible that one shell with two different radii and the other shell is formed with continuously decreasing radius or similar.
- the platform and / or the seat is assigned a support of an elastic, anti-slip material.
- the seat is cushioned when tilting against the platform and braked at the same time. No user sits on the seat, tilts it on the platform and is held here by the anti-slip property of the material, so that it does not fall. At the same time a shock against the platform is cushioned when the user sits on it, which in turn makes comfort noticeable.
- the support can be the same height, higher or lower than the corresponding shell.
- the seat device may have a backrest, which is arranged fixed relative to the seat surface. It is particularly preferred if the backrest is attached to the platform or on a frame supporting the frame in particular depth adjustable and releasably. Such a backrest can support a uncontrolled movement of the user in a timely manner when tilting the seat in the direction of the backrest to the rear. It is essential that the backrest does not affect the movement of the seat in any way, so that caused by the movable seat mobilization of the spine and strengthening of the corresponding holding (trunk) muscle is not hindered by this movement affecting backrest. Such a trained backrest thus also allows the change from an active seating position to a rather passive seating position.
- POM polyoxymethylene
- the ball is preferably made of a metal, in particular of stainless steel (stainless steel).
- stainless steel has good slide bearing properties in combination with the POM cups.
- a steel ball has a high dead weight, which helps that the ball safely remains in the shell associated with the platform.
- the combination of a metal ball with a plastic shell also leads to a reduction of rolling noise of the ball in the shells.
- bowls and balls may both be made of metal (e.g., aluminum, stainless steel, etc.) or of POM and other materials such as e.g. Wood, stone, or glass are made.
- the seat can be made of wood, plastic or metal and optionally covered with a textile, leather or the like, optionally with an intermediate layer of a soft, resilient material such as foam or the like ,
- the seat plate is preferably oval or elongated, whereby this gives the possibility that a user while sitting down or getting up laterally hold on the seat plate and this can stabilize first.
- one of the shells is designed as a ball bearing, in which the tilting element is freely rotatably received.
- the seat or / and the platform and the respective associated shell can be made in one piece, in particular be made of the same material.
- a two- or multi-part design is possible in which the shells and the seat or the platform are materially connected and / or positively connected with each other, for example, welded, glued, screwed or the like.
- the invention relates to the use of the seat assembly as an active seating device in the field of therapy, particularly traditional physiotherapy, Pilates, Gyrotonic®, Feldenkrais, workspace seat training and health coaching.
- the presented seat device allows in addition to a passive sitting, a favorable active sitting.
- Particularly beneficial effects are the conscious or reactive coordination training, an increased perception of posture, the improvement of the intra- or / and intermuscular coordination as well as the strengthening and mobilization of the entire trunk musculature.
- Such self-control is in known seating devices for active sitting, such as air-filled cushions or balls, difficult to achieve, because these known seating devices rather sluggish react in the movement.
- the seat device according to the invention allows an extraordinary ease of simultaneous rotation, tilt, and displacement movements to this active sitting from the sitter can also be particularly advantageous under the guidance of traditional physiotherapy, Pilates, Gyrotonic®, PC seat training and general health coaching. In such a case, the seat assembly is used for therapeutic purposes.
- the illustrated seat device has a platform 10 and a seat 11. Under the platform 10 may still be a conventional, optionally mounted on wheels frame, which may also be adjustable in height in the usual way, as this is known, for example, office chairs. The platform 10 may also be placed directly on the floor or other surface.
- a shell 12 is arranged and fastened by means of screws 13.
- the shell 12 has a concave, up to the seat 11 open
- the seat 11 On the underside, that is, the side facing the platform 10, the seat 11 is also a shell 15 with a downward, so the platform 10 out, concave recess 16 is mounted. She is as in Fig. 1 to 3 recognizable, by a bolted to the seat 11 (screws 17) collar 18 secured. Between the shells 12, 15, a tilting device, namely a ball 19, is arranged, which supports the seat 11 on the platform 10.
- the convex recesses 14, 16 in the shells 12, 15 are designed so that in the central region 20 they have a much larger radius R compared to the spherical radius. In an edge region 21, the radius r is smaller than the radius R in the central region 20, but still larger than the spherical radius (FIG. Fig. 4 ). In that regard, the convex recesses 14, 16 of the shells 12, 15 are identical and also provided with the same radii R, r.
- a collar 22 Around one of the shells 12, 15 around a collar 22 is arranged made of an elastic and non-slip material.
- the collar is preferably only overlaid and interchangeable. Depending on the strength of the collar, the size of the tilt angle of the seat can be changed, which has an effect on the degree of difficulty when sitting. Instead, a replaceable, solid ring such as wood or plastic, the platform and the seat firmly connect. This allows the choice between a movable and a stationary seat.
- the collar 22 is arranged around the shell 10 associated with the shell 12 and has the same outer diameter as the platform 10, but this need not necessarily be the case.
- the collar 22 encloses with its central bore 23 a shell 24 of the shell and is held in such a force-locking manner.
- the seat 11 is associated with the collar 18 at maximum tilting of the seat 11 on the platform 10 associated collar 22.
- the ratio of the diameter of the collar 22 to the collar 18 on the seat and the anti-slip properties of the collar 22 prevent the seat 11 completely from slipping off the ball 19 and thus the platform 10.
- the elastic property provides some cushioning when the user tilts the seat 11 so much that the collars 18 and 22 collide.
- the seat device shown has only one shell 12, 15 on the platform 10 and the seat 11 on course can also, as in the DE 103 57 162 B4 shown, three shells each be provided
- FIG. 5 is a further embodiment of an upper shell 15 'shown in cross section.
- This shell 15 ' is characterized in that it has three different radii r1, r2 and r3 in the radial direction from the center 30 of the shell 15' to the peripheral edge 32, wherein the radius r3 is smallest.
- Such a shell 15 ' can also be used as the lower shell 12'.
- the ball is in the center 30 at the lowest point of the lower shell 12 and 12 ', which is based on the peripheral edge 32 by the size h lower. From the representations of Fig. 1-5 It can also be seen that the ball in a movement having a radial component, a constantly changing vertical position with respect to the platform (10) ( Fig. 1-3 ) occupies. A constant vertical position is assumed by the ball only in a circumferentially occurring rolling movement of the ball when the radial distance to the center 30 remains constant (no radial component of the movement).
- the additional, smaller radius r3 causes a greater resistance in the movement of the ball in the shell 12 'or 15' than the slightly larger radius r2, so that a stronger slowing down movement of the ball and thus the seat surface is achieved when the ball in the edge region of the shell 12 'and 15' is moved. Due to the larger slope, which has the radius r3, this shell allows 12 'or 15' an even better grip of the ball and excludes falling out or jumping out of the ball from the shell under load completely.
- FIG. 6 shown seat assembly of a third embodiment, which from the Fig. 1-3 known components, which are provided with the same reference numerals, but will not be explained further.
- the upper shell 15 'of this seat device is in the Fig. 5 illustrated shell with three different radii r1, r2 and r3.
- the ball In a maximum tilted seat 11, which rests on the collar 22, the ball is in a transition region between the shell radii r2 and r3 of the upper shell 15 'on Further, it is in the lower shell 12, which in this example has two different radii, in the range of the smaller radius r ( Fig. 4 ) on.
- FIG. 7 From the FIG. 7 is an embodiment can be seen in which a geieri medicinal on the platform 10 depth adjustable and removable backrest 40 is indicated.
- the backrest 40 is configured such that it does not affect the movement of the seat 11 and is not touched by a user in the normal case during the execution of movements.
- the illustrated backrest is intended to provide support for the rearwardly moving user's back when the seat surface 11 is tilted backwards in the direction of the backrest 40 and when the backrest movement is not carried out by the user, so that falling down of the seat device is precluded can.
- An Indian FIG. 7 indicated frame 42 of the seat device may have a height adjustment, for example in the form of a gas spring, wherein in the figure an actuating ring 44 is indicated for the gas spring.
- the frame has in its lower part a base for a stable stand, preferably with five feet, as is common for office / tilt chairs. On the feet can optionally be provided under load self-locking rollers that allow easy movement of the seat assembly in the unloaded state and ensure a secure state of the seat assembly in the loaded state.
- the fourth embodiment according to Fig. 8 shows that the shell 12 "is formed in the platform as a ball bearing 46, in which the ball (tilting element) 19 is freely rotatably mounted.
- the seat 15 of the associated shell 15 has the concave curvature with two or three different radii, so that the seat 11 is free to move relative to the fixed platform 10 and in this embodiment to the rotatable but horizontally and vertically fixed ball 19. The same effects are achieved as in an embodiment without ball bearings 46.
- the diameter of the shell in the seating surface has to be increased slightly with a corresponding adjustment of the radii of curvature of the shell, in order to allow a sufficient freedom of movement for the seating surface with respect to the platform
- the ball bearing can be designed such that the tilting element is held therein, ie not out fall out of the ball bearing orndg can be taken. In such a case, it would also be conceivable that the ball bearing is designed in the shell of the seat.
- the presented seating device can be used and used for therapeutic purposes, for example in rehabilitation centers, physiotherapies and the like. In particular, it can also be used for various types of gymnastics, such as Pilates or Gyrotonics® and the like. In addition to this therapeutic field of application, the seat assembly can also be used as an active seating in the private sector or in the office. Finally, it can also be thought to accommodate a seat assembly of platform, tilting element and seat in a wheelchair, so that a mobilization of the spine for paraplegics is possible.
