Description

Toilet seat and seat swivel device

One aspect of the invention relates to a toilet seat for supporting physiological bladder and defecation.

US 4,254,514 relates to a toilet seat having front, rear and side sections defining an upper seating surface and an associated lid. The seat extends upwardly concave from the front to the rear of the toilet seat. Furthermore, a footrest is arranged at the front portion of the toilet seat to cause a physiologically favorable sitting position during evisceration through the seat shape and the footrest.

In US 4,457,029 an annular toilet seat is described having a surface having a raised front segment and an elevated rear segment. The two segments are connected by inclined against the horizontal intermediate segments. A heart-shaped contour line, which indicates the edge of the highest points, extends through the middle region of the front and rear segments and along a central opening into the intermediate segments. The posterior raised element is said to stimulate intestinal perestalsis and emptying.

US 4,175,294 discloses a toilet seat having a beaded upwardly rounded portion at the front end. In addition, an inclined footrest is arranged on the toilet bowl on the floor. These features cause the user's feet to be at a certain angle to the ground and the legs in one position so that an angle between thigh and calf is set between 40 ° and 50 °, and set a more physiologically favorable position becomes.

US 2,099,118 relates to a toilet seat with a physiologically favorable sitting position. The surface is concave upwardly from a front portion to a rear portion of the toilet seat. The caused by the known toilet seats support the physiological bladder and bowel movement is limited, with the occupied for emptying the bladder and bowel sitting posture on the known toilet seats no physiologically correct posture and usually perceived as less pleasant.

Object of the present invention is to provide a toilet seat of the type mentioned above, which contributes to the occupied by the emptying of the bladder and intestines sitting posture on the toilet seat to a much better support the physiological bladder and bowel evacuation, which on the toilet seat taken posture is perceived as pleasant. Moreover, it is an object of the present invention to provide a toilet seat of the type mentioned above, which is characterized by a high level of comfort and allows easy sitting down and getting up.

The above objects are achieved in a toilet seat with the features of claim 1. The angle data according to the invention relate to a relaxed sitting position on the toilet seat according to the invention, which, however, is dictated by the shape of the seat surface to the user.

According to the invention, it has surprisingly been found that the physiological bladder and defecation can be influenced to a significant degree by specifying a certain angle between the femoral axis and the trunk axis of the user positively. Hereby, the puborectal sling in the area of the pelvic floor musculature is of crucial importance, as it causes an acute-angled bending of the rectum by means of a special suspension inside the bony pelvis and thus prevents the gravitational pressure on the lower sphincter apparatus in an energy-saving manner. The squat position or posture which is predetermined when sitting on the toilet seat according to the invention and largely corresponds to the natural squat position of the human during bladder and defecation makes passive slackening of the puborectal sling possible and thus a door opening for free passage of the chair. The triggering moment for the defecation is not the pressure increase of the abdominal cavity by pressing the abdominal press, as in the prior art often falsely assumed, but a certain Köφerhaltung, which should largely correspond to the natural squat position. As a result, the seat position of a user predetermined by the shape of the seat provided according to the invention provides undisturbed bladder and defecation. The toilet seat according to the invention can therefore be used advantageously for the treatment of bowel dysfunction. Hemorrhoids, fissures, fistulas, and prolapses to colorectal cancer can be prevented.

Further preferably, the seat surface may be formed in such a way and define a position of the user when sitting on the seat surface such that the angle between the thigh axis and a horizontal axis is less than 20 °, preferably less than 10 °. In this case, a seat height is perceived as pleasant if approximately a right-angled position is achieved in the upper jump and knee joints. Of course, this also depends on the height of the toilet keys or the location of the attachment of the toilet bowl on a wall. Moreover, the angle between the fuselage axis and a vertical axis may preferably be between 20 ° to 50 °, in particular between 30 ° to 40 °. The sitting position achieved with the aforementioned angle data also has a positive effect on undisturbed bladder and defecation.

In addition, it has been recognized in the context of the invention that when sitting on the toilet seat according to the invention, the spread of the O- thigh between 50 ° to 80 °, preferably between 60 ° to 70 °, may be to the bladder and bowel movement continues to support. The angle between thigh axis and lower leg axis may preferably be between 60 ° to about 90 ° or more.

Moreover, the erfϊndungsgemäße toilet seat with or without footstool or the like can be used, which ultimately depends on the height of the toilet seat or the height of the toilet bowl or the amount of attachment of the toilet bowl on the wall.

In order to achieve a natural squat position of the human during the emptying of bladder and intestine by the special shape of the toilet seat according to the invention To ensure zes, the height difference between the rear elevation and the front elevation of the toilet seat may be more than 15 mm, preferably more than 20 mm, in particular more than 40 mm, each based on the height difference between the highest point on the back Raise and the highest point on the front elevation of the toilet seat.

In the context of the invention it has been found that a particularly good support of bladder and defecation is ensured when the pitch of the seat in the longitudinal direction with respect to the course of the highest points on the seat in a first area less than ± 1% and / or in a second range -30% to -50%, and / or in a third range -80% to -100% and / or a fourth range -40% to -60% and / or in a fifth range less than -15%, preferably -10%, and / or in a sixth range less than + 10% and / or in a seventh range + 10% to + 30% and / or in an eighth range + 30% to + 50% and / or a ninth range + 10% to + 30%, in each case based on a width of the region in the longitudinal direction of the seat frame of 40 mm to 60 mm, preferably of about 50 mm.

In another embodiment of the seating surface, which likewise very effectively supports bladder and defecation, the inclination of the seat surface in the longitudinal direction with respect to the course of the highest points on the seating surface in a first area may be less than ± 1% and / or in a second area. rich -20% to -40% and / or in a third range -60% to -90% and / or in a fourth range -30% to -50% and / or in a fifth range less than -10%, preferably less than -5%, and / or in a sixth range less than + 20%, in particular less than + 10%, and / or in a seventh range between + 20% to + 40% and / or an eighth range between +40 % to + 60% and / or in a ninth range between + 20% to + 40%, also based on a width of the region in the longitudinal direction of the toilet seat of 40 mm to 60 mm, preferably of about 50 mm. The gradients indicated above always refer to the difference height of a start and an end point of a longitudinal region in the longitudinal direction of the toilet seat.

Another aspect of the invention relates to a toilet seat having a pivotally attachable to a toilet bowl base plate and a pivotally mounted on the base seat cradles, wherein the base plate rests in the assembled state of the toilet seat on the toilet bowl and a first axis of rotation at the rear end of the Grundplat - te is pivotable together with the seat upwards and wherein the seat frame is pivotable about a second axis of rotation at the front end of the base plate relative to the base plate upwards. This aspect can also be realized independently of the aspect described above. The toilet seat described above is characterized by a simple structural design with high stability. Moreover, it allows the selected construction of the toilet seat according to the invention due to the pivoting of the seat frame relative to the base plate to use in a simple way damping elements or lifting devices for lifting the rear end of the seat in order to increase the seating comfort and / or a certain inclination of the Preserve goggles, which can have a positive effect on the bladder and defecation and can facilitate the emergence after completion of bladder and defecation. This will be discussed in detail below.

A third aspect of the invention relates to a toilet seat having a toilet seat pivotally mounted on a toilet seat and with a hinged toilet lid, wherein a height adjustment is provided for lifting the seat and the flip cover at the rear end of the toilet seat. This aspect of the invention can also be implemented independently of the aspects described above.

A further aspect of the invention, which may also be provided independently of the aspects described above and if necessary combined with the features described above, relates to a seat pivoting device for a toilet seat as a stand-up aid, with a support for two fastened to a toilet bowl for the side next to the toilet bowl to be arranged lifting cylinder, the lifting cylinder are held only on the carrier and are supported on the carrier when lifting the toilet seat only on the toilet tenschüssel. In addition, the present invention relates to an arrangement with a toilet seat and a seat pivoting device of the aforementioned type and a toilet arrangement with a toilet bowl, a toilet seat and a seat pivoting device of the aforementioned type. Lifting devices for toilet seats as a stand-up are already known from the prior art. DE 196 15 567 A1 discloses a seat lifting device for a stool or a chair, for example a toilet bowl, which consists essentially of three units which can be assembled, namely two lifting units arranged on the left and right of the pool and one connecting frame interconnecting the lifting units , Each lifting unit has a guiding and lifting device and a cable drive, which are connected to each other via guide cables for traction cables. Each guide and lifting device has a guide rail on which a sliding plate is displaceable. On the slide plate, a seat support is pivotally mounted, wherein a gas spring is provided, which presses the rear portion of the seat support up, so that the seat support and the seat mounted on it tilt forward. The known seat lift device is intended to perform a vertical, powered movement of the seat of a toilet bowl to assist physically disabled or elderly persons when they want to sit on the toilet seat or get up from it again.

From DE 42 15 448 Al a water closet for physically disabled, especially in the area of people with disabilities, with a stationary dishwashing bowl and a seat arranged thereon is known, which can be raised and lowered by a arranged between the floor and the seat lift. In one embodiment of the known water closet a base frame is provided, which rests on the upper annular edge of the sink. On the base frame a folding frame is connected at the front by a hinge, so that the folding frame can be folded forward to the top. The seat frame is attached to the folding frame and articulated by a hinge at the rear end of the folding frame. At the rear end of the basic frame, an L-shaped boom projecting downwards behind the dishwashing bowl is provided, on the angled part of which an actuating cylinder is articulated. The piston rod of this actuating cylinder is in turn mounted at the bottom of the snap frame by a hinge on this. By actuation of the actuating cylinder, the folding frame is pivoted upwards about the joint on the front of the basic frame, in order to facilitate getting up or else sitting down or sitting a person. Another seat lift device is known from US 4,993,085, in which a toilet seat with a correspondingly formed device from the edge of the toilet bowl is fully raised and thereby folds down to facilitate getting up.

The known from the prior art devices for raising or pivoting the toilet seat have a structurally complex structure and can not be retrofitted in existing toilet facilities in the rule. The complex structural design of the known seat lifts with a variety of components that make up the seat lift, contributes to high manufacturing costs and increases the susceptibility. Incidentally, the operation of the known seat lifts, in particular for old and disabled people is not fully possible. This has meant that the known seat lift devices achieve only low acceptance among the addressed target groups.

In particular, the seat pivoting device should advantageously be used in conjunction with the support of the physiological bladder and defecation by the toilet seat described above. In addition, the seat pivoting device according to the invention should be producible at low cost. Finally, the seat pivoting device according to the invention should be operable in a simple manner, in particular for elderly or disabled users, and allow a comfortable sitting down, sitting and getting up on or from the toilet bowl.

The above object is achieved by a seat pivoting device with the features of claim 11. It is provided that the reciprocating pistons are arranged with respect to the longitudinal axes pivotally to the longitudinal axis or to the level of the toilet seat or indirectly or directly pivotally connected to the toilet seat. It is essential that it can come on the extension of the reciprocating piston to a relative movement between the reciprocating piston and the toilet seat, so that the toilet seat when lifting from the rear on the reciprocating piston at least a front bearing point of the toilet seat on the toilet bowl is pivoted upwards. As a result, the toilet seat is tilted when lifting from back to front. The traverse may preferably be web-shaped. The lifting cylinders can be rigidly fastened or attached to the crosshead via an elastic sleeve with spring-loaded degrees of freedom.

In a toilet assembly according to the invention with a toilet bowl, a toilet seat and a seat pivoting device of the aforementioned type is accordingly provided that the toilet seat attached to a rear end liftably attached to the seat pivoting device and is supported behind the seat pivoting device on the toilet bowl, the toilet seat with a front end rests on at least one support point on the toilet bowl unpaved and when lifting from behind the support point is pivotable forward.

The seat pivoting device according to the invention can be easily attached to a toilet bowl or mount and retrofit existing toilet facilities. In addition, the inventive seat pivoting device is characterized by a simple structural design with a small number of parts, which allows the production of the seat pivoting device at low cost and at the same time greatly reduces the susceptibility to interference during operation. The structurally simple structure allows a compact design with an elegant design, which further increases the acceptance of the user compared to the seat pivoting device according to the invention. Finally, the seat pivoting device according to the invention is characterized by a simple operation and offers a user the ability to support the sitting and getting up or from the toilet seat in a very comfortable way.

In FIGS. 1 a to 1 c, a seat frame 1 of a toilet seat 2 shown in FIGS. 5 and 6 is shown, wherein the seat frame 1 has a seat surface 3 adapted to the natural squat position of the human during bladder and defecation. The seat surface 3 is formed trough-shaped or inwardly curved and is formed by a central lower seating area 4 between see a rear elevation 5 and a front elevation 6 of the seat 3. The rear elevation 5 has a greater height than the front elevation 6. The height difference is approximately 21 mm with respect to the highest points of the respective elevation 5, 6. Moreover, the seat surface 3 is formed such that a (sitting) posture of a user 7 when sitting on the seat surface is predetermined such that the angle α between the thigh axis Y ₁ and the trunk axis Y _{2 of} the user 7 about 50th ° is. The angle β between the thigh axis Y ₁ and the horizontal axis Y ₃ is about 10 °. The angle γ between the fuselage axis Y ₂ and a vertical axis Y ₄ is about 30 °. This is shown in FIG. 2. The aforementioned angles are predetermined by the shape of the seat surface 3 when sitting on the toilet seat. The values for the slope of the seat 3 in Longitudinal direction X with respect to the course of the highest points on the seat surface 3 results from FIGS. 1 a to 1 c and, based on a width of the regions a i of 50 mm:

The aforesaid values for the pitch of the seat surface 3 are relative to the start and end points of a region a-i in the longitudinal direction X and to the region width. The lengths, heights and width dimensions given in FIGS. 1a to 1c are given in [mm].

FIGS. 3 a to 3 c show a seat frame 1 with a different shape of the seat surface 3. As is apparent from Fig. 4, which shows a user 7 in the sitting position when sitting on the seat 3 shown in Fig. 3a to 3c, the seat surface 3 is formed in this embodiment, and provides an attitude of the user 7 such that the angle α between the upper limb axis Y ₁ and the trunk axis Y _{2 is} approximately 50 ° and the thigh axis Yi runs in the horizontal direction. The angle γ between the fuselage axis Y ₂ and a vertical axis Y ₄ is about 40 °.

The height difference between the rear elevation 5 and the front elevation 6 of the seat surface 3 is approximately 50 mm in the embodiment illustrated in FIGS. 3a to 3c. The pitch of the seat 3 in the longitudinal direction X with respect to the course of the highest points on the seat 3 is shown in FIGS. 3a to 3c with respect to a width of the areas a-i in the longitudinal direction X of 50 mm, as indicated below:

It is understood that the dimensions indicated in FIGS. 1 a to 1 c and FIGS. 3 a to 3 c can each differ by ± 5%. The seat glasses 1 shown in Fig. Ia to Ic and 3a to 3 c support the natural squat position of humans and thus facilitate complete bladder and defecation. As can be seen from FIGS. 2 and 4, the angle δ between the thigh axis Yi and the lower leg axis Y _{5 is} between 80 ° (FIG. 2) and 90 ° (FIG. 4). Moreover, by the shaping of the seat surface 3, a spread of the thighs between 60 ° to 90 °, preferably between 70 ° to 80 °, given. This contributes to further support in bladder and defecation.
