Description

The invention relates to a pendulum suspension device for pendulum suspension of a support body according to the preamble of claim 1. Furthermore, the invention is directed to a support arrangement with at least one such pendulum suspension device.

For many people, prolonged standing, sitting, and / or lying is a significant burden. In general, only certain muscles or muscle groups are consistently exposed over a longer period of time while others are not activated at all. Such uninterrupted tension of individual muscles or muscle groups can easily lead to tension, especially in the area of the spinal column. A reduced well-being, a decrease in the ability to concentrate and damage to health can be the result. In order to avoid such consequences, regular exercise, targeted supportive muscular training and therapeutic measures are recommended. Such measures are time consuming and expensive.

The following is with reference to the Fig. 4 a third embodiment of the support arrangement explained. Identical parts are given the same reference numerals as in the first embodiment, the description of which is hereby incorporated by reference. Structurally different, but functionally similar parts receive the same reference numerals with a subordinate "b".

The support arrangement is designed here as a stand-up arrangement. This comprises a base 1b comprising a foot body 17 and a support frame 18 extending upwardly from the foot body 17. The foot body 17 is preferably designed plate-like and may have a plurality of bottom feet 19 below. The foot body 17 is supported against a background.

On the support frame 18, the first holding means 5b is arranged above. On the holding arms 11 b of the first holding device 5 b, the pendulum suspension devices 4 are suspended via their first attachment devices 12.

The following are with reference to the Fig. 5 to 11 various embodiments of the pendulum suspension devices 4 described in more detail, each of which can be found in the support arrangements disclosed here application. Since the pendulum suspension devices 4 used in the various support arrangements are each preferably identical, only one of the pendulum suspension devices 4 will be described below.

According to Fig. 5 the pendulum suspension device 4 has a longitudinal central axis 19, which runs vertically, for example, in the unloaded or uniformly loaded state of the pendulum suspension devices 4. It is substantially rotationally symmetrical to the longitudinal central axis 19 and extends along the same.

The pendulum suspension device 4 has a first or upper end portion 20 and a second and lower end portion 21, respectively. Between the first end portion 20 and the second end portion 21, a connection portion 22 extends. In the first end region 20 is the first attachment means 12, while in the second end region 21, the second attachment means 15 is arranged.

The first or upper fastening device 12 comprises a first sleeve body 23 and a first bearing body 24. The first bearing body 24 is substantially hemispherical-shaped and has an outwardly facing first bearing surface 25, which thus is uniform is curved.

The first bearing body 24 also has a first bearing surface 25 facing away from the first flat surface 26, from which a first continuous receptacle 27 extends along the longitudinal central axis 19 to the first bearing surface 25. The first receptacle 27 is executed stepwise. In the area of the flat first surface 26, the first receptacle 27 is wider than in the first bearing surface 25.

The first sleeve body 23 has a cylindrical first tube sleeve 28 with an open first end 29 and a first plate-shaped fixing piece 30, which adjoins the first tube sleeve 28 opposite to the first end 29 and preferably radially with respect to this protrudes outwards. The first tube sleeve 28 and the first fixing piece 30 are preferably made in one piece. The first fixing piece 30 engages positively in the first receptacle 27 and abuts flat with its inner, first planar fixing surface 31 on an inner first step surface 32 of the first bearing body 24, which is transverse to the longitudinal central axis 19 extends. The first tube sleeve 28 preferably passes through the first bearing surface 25 and protrudes radially relative to the same in the direction of the longitudinal central axis 19.

The first bearing body 24 and the first sleeve body 23 are preferably pivotable about the longitudinal center axis 19 relative to each other. However, they are with respect to the longitudinal center axis 19 unverkippbar each other. The first bearing body 24 and the first sleeve body 23 are only together and similar to the longitudinal central axis 19 transversely to this tiltable or pivotable.

The first bearing body 24 engages with its first bearing surface 25 at the top in the first holding device 5, which has a complementary to the first bearing surface 25 first bearing receptacle 33 or -Pan. The first bearing receptacle 33 is followed by a first continuous push-through opening 34, whose diameter is substantially larger than the outer diameter of the first tube sleeve 28. The first tube sleeve 28 preferably passes through the first push-through opening 34.

Opposite to the first bearing body 24 is located on the first holding device 5, a first spring element 35, which is designed annular. The first tube sleeve 28 preferably passes through the first spring element 35 axially in the direction of the longitudinal center axis 19. The first spring element 35 is preferably formed from a resilient material, such as plastic or rubber. Alternatively, at least one plate spring, coil spring, fluid spring or the like can be used.

Opposite to the first holding device 5 is located on the first spring element 35, a first receiving element 36 at. The first receiving element 36 is circular in cross section. It has a first inner receiving opening 37 which widens in the direction of the longitudinal central axis 19 of the first spring element 35 going away. The first tube sleeve 28 preferably penetrates the first receiving element 36 axially in the direction of the longitudinal central axis 19.

The second and lower attachment means 15 is similar to the first attachment means 12 is formed. This includes a second tube sleeve 38 which is open at its second end 39. The second end 39 of the second tube sleeve 38 faces the first end 29 of the first tube sleeve 28. The second tube sleeve 38 carries an external thread 40 which extends in an adjacent area to an end 41 opposite the second end 39. On the outer thread 40, a fixing nut 42 is turned on. The fixing nut 42 rests on the inside on a second bearing body 43 of the second fastening device 15, which has a half-spherical cap portion 44 with a uniformly curved second bearing surface 45. The second bearing surface 45 faces the first bearing surface 25.

Further, the second bearing body 43 has a second receptacle 46 which is open on the side facing away from the first attachment means 12 side of the second bearing body 43 to the outside. The fixing nut 42 is located in the second receptacle 46 and is located on the inside on an inner second step surface 47 of the second bearing body 43, which extends perpendicular to the longitudinal central axis 19.

The second tube sleeve 38 preferably passes through the semi-spherical cap portion 44 and protrudes radially with respect to this in the direction of the longitudinal central axis 19.

The second tube sleeve 38 and the second bearing body 43 are preferably pivotable about the longitudinal center axis 19 relative to each other. However, they are opposite to the longitudinal central axis 19 unverkippbar each other. A tilting with respect to the longitudinal central axis 19 transversely to this is only possible together.

The second bearing body 43 engages with its half-spherical cap portion 44 below in a second bearing receptacle 48 or -Pan in the second holding means 6, which is complementary to the second bearing surface 45. The second holding device 6 also has a second push-through opening 49 which is significantly larger in diameter than the outer diameter of the second tube sleeve 38 and adjoins the second bearing receptacle 48.

Opposite to the second bearing body 43, the second holding device 6 is adjoined by a second receiving element 50, which is identical to the first receiving element 36. It has a second receiving opening 51, which widens in the direction of the longitudinal central axis 19 to the first holding device 5 out. In the second end region 21 no spring element is provided here. Alternatively, there is at least one second spring element, which is designed according to the first spring element 35.

In the first tube sleeve 28 and the second tube sleeve 38 engages a soul 52, which is firmly connected thereto. The connection can be made, for example, by compressing the tube sleeves 28, 38. The core 52 connects the fastening devices 12, 15 with each other. Alternatively, a connection of the core 52 to the first or second bearing body 24, 43 without tube sleeve 28, 38 or with a shortened tube sleeve 28, 38th

In the connection region 22 extends a stabilizer element 53 which is tubular. It engages the first receiving opening 37 and the second receiving opening 51, each having the stabilizer element 53 transverse to the longitudinal center axis 19 center. The stabilizer element 53 surrounds the core 52 in the radial direction.

Between the first attachment means 12 and the second attachment means 15 extends a damping element 54 which surrounds the core 52 and the stabilizer element 53 in the radial direction. The damping element 54 preferably extends substantially the entire length of the core 52. The damping element 54 has a plurality of relatively rigid bead-like bodies 55, the diameter of which is greatest in the center of the connection region 22 and to the end Areas 20, 21 decreases in each case.

The damping element 54 is circular in cross section. Between adjacently arranged bead-like bodies 55 each elastic intermediate elements 56 are provided. The bead-like bodies 55 and the elastic intermediate elements 56 are preferably integrally connected to each other. Alternatively, these are carried out separately and positively, positively or materially connected to each other.

Hereinafter, the function of the pendulum suspension device 4 and the enclosing this support arrangement will be described. As already mentioned, the first holding device 5 is swingably connected to the second holding device 6 via the pendulum suspension devices 4. The support surface 3 is thus oscillatable or oscillating connected to the base 1.

In normal sitting, standing or lying on the support body 2; 2a; 2b this is vibrated in a horizontal plane, resulting in lateral deflections of the support body 2; 2a; 2b leads. Such oscillating bodies Run approximately in a horizontal plane and have only a small vertical component. This is via the second holding device 6; 6a; 6b transferred to the pendulum suspension devices 4 that perform pendulum movements.

The damping element 54 causes an amplitude-dependent, progressive damping of the pendulum movements. The damping in the range of small pendulum amplitudes is largely negligible, so that the pendulum suspension devices 4 in this area essentially free, that is undamped, can swing. The elasticity of the damping element 54 and the arrangement of the bead-like body 55, the mechanical properties of the pendulum suspension devices 4, such as the maximum achievable under normal circumstances pendulum amplitude, can be significantly influenced. The stabilizer element 53 supports this damping and also influences the mechanical properties of the respective pendulum suspension device 4. Further, the stabilizer element 53 prevents buckling of the respective pendulum suspension device 4th

The length of the core 52, however, has a direct influence on the intrinsic frequency of the pendulum suspension device 4. The natural frequency of the pendulum suspension devices 4 is in the range of 0.1 Hz to 10 Hz, in particular in the range of 0.5 Hz to 5 Hz.

In the unloaded state or evenly loaded state of the pendulum suspension devices 4, the soul 52 extends along the respective longitudinal center axis 19. The soul 52 is taut.

The first bearing body 24 is pressed with its first bearing surface 25 by the first fixing piece 30 against the first holding means 5, while the second bearing body 43 with its second bearing surface 45 via the fixing nut 42nd is pressed to the second holding device 6.

The first spring element 35 and - if present - the second spring element exert a certain compressive force or biasing force on the stabilizer element 53.

The pressure force is adjustable by adjusting the fixing nut 42. The farther the fixing nut 42 is moved in the direction of the first holding device 5, the greater the pressure force. The effective pendulum length and thus the vibration behavior of the respective pendulum suspension device 4 is also adjustable. The fixing nut 42 also allows easy installation.

When the pendulum suspension devices 4 are deflected in use transversely to the corresponding longitudinal central axis 19, the vertical distance between the first holding device 5 and the second holding device 6 shortens. In this deflection, the first bearing body 24 tilts opposite the first holding device 5 and / or the second bearing body 43 relative to the second holding device 6. The first bearing body 24 and the first holding device 5 thus form a first oscillating bearing, while the second bearing body 43 and the second holding device 6 form a second swing bearing. Due to the swing bearings, the pendulum suspension devices 4 are extremely vibratory and have a very fine response. The core 52 then runs at times obliquely to the longitudinal central axis 19. The first spring element 35 and - if present - the second spring element same the reduction in the distance between the first holding means 5 and the second holding means 6 substantially, so that the stabilizer element 53 is further exposed to substantially no changed pressure. The stabilizer effect of the stabilizer element 53 remains essentially unchanged due to the deflection of the respective pendulum suspension device 4.

The following is with reference to Fig. 6 an alternative embodiment of a pendulum suspension device described. Identical parts are given the same reference numerals as in FIG Fig. 5 , whose description is hereby referred to. Structurally different, but functionally similar parts receive the same reference numerals with a subordinate "a".

In contrast to the pendulum suspension device 4 according to Fig. 5 has the in Fig. 6 illustrated pendulum suspension device 4a, a first stabilizer part 57 and a second stabilizer part 58, which together form the stabilizer element 53a. The stabilizer parts 57, 58 are arranged in the direction of the longitudinal central axis 19 separated or spaced from each other.

The first stabilizer part 57 engages in the first receiving opening 37, while the second stabilizer part 58 engages in the second receiving opening 51.

The stabilizer parts 57, 58 may have an identical or different length in the direction of the longitudinal central axis 19. It is advantageous if the first stabilizer part 57 and the second stabilizer part 58 each extend over a length along the longitudinal central axis 19, the between 5% and 40%, more preferably between 7% and 20%, of the total length of the respective pendulum suspension device 4a.

The damping element 54a has for this in comparison to the embodiment according to FIG Fig. 5 preferably an increased wall thickness transversely to the longitudinal center axis 19. It can also act as a spring or compensating between the stabilizer parts 57, 58. The damping element 54a thus also intercepts a reduction in the spacing of the holding devices 5, 6 relative to one another. The first stabilizer part 57 and / or the second stabilizer part 58 presses against the damping element 54a, which can be elastically deformed.

The following is with reference to Fig. 7 Another embodiment of the pendulum suspension device described.

In contrast to the embodiments according to Fig. 5 . 6 the spring element 35b is arranged at a distance from the first holding device 5. It is located in the connection area 22b. More specifically, it is disposed between the first stabilizer part 57b and the second stabilizer part 58b. The first stabilizer part 57b rests with its free end 59 on one side of the spring element 35b, while the second Stabilizer part 58b rests with its free end 59 on the other side of the spring element 35b. The spring element 35b is preferably arranged centrally between the holding devices 5, 6. The stabilizer parts 57b, 58b are displaceable in the direction of the longitudinal central axis 19 relative to each other.

It is advantageous if the stabilizer parts 57b, 58b interengage in some areas so as to have a guide between them in the direction of the longitudinal central axis 19.

The spring element 35b may bear on the inside of the damping element 54 on the circumference. It begins again a reduction in the distance of the holding devices 5, 6 to each other. The first stabilizer part 57b and / or the second stabilizer part 58b presses against the spring element 35b, which is elastically deformed.

It is again essentially cup-shaped and essentially has a constant material thickness. Thus, in addition to its outer second bearing surface 45, it has an inner second bearing surface 65.

The fixing nut 42 c has a second abutment surface 66, which is curved outwardly and is complementary to the inner second bearing surface 65 is executed. The fixing nut 42c and the second bearing body 43c are tiltable relative to each other across the longitudinal center axis 19. As a result, the ability to vibrate or the response behavior of the pendulum suspension device is further improved.

In the second bearing surface 45, a second recess 68 extending around the longitudinal central axis 19 is provided to form a second collar surface 67. The second collar surface 67 extends transversely to the Longitudinal axis 19 and the second holding device 6 faces. It forms a lubrication groove.

The following is with reference to the 10, 11 a further embodiment of the first attachment means and second attachment means described. Identical parts are given the same reference numerals as in the previous embodiments referred to. Structurally different, but functionally similar parts receive the same reference numerals with a subordinate "d".
