Definitions

  • the invention relates to a damping device, in particular to dampen the swiveling movement of toilet seats and / or lids, with a housing that with a Damping fluid is filled, an axis that rotates in the Housing is arranged and the one outside the housing has lying first axis section, at least one wing connected to the axis, which together with the axis and the inside of the housing at least a first and a defines the second chamber, the damping fluid being used for damping at least on a first flow path from the first flows into the second chamber.
  • rotary damper is known.
  • a rotary damper with a central axis of rotation which has two diametrically opposed wings.
  • the Sashes define a connection opening with the inner wall of the housing for the passage of the fluid. If the axis of the Turned damper, the damping fluid flows through the connection opening from one chamber to the other and dampens the axis movement.
  • a rotary damper is also known in practice, whose axis is also rotatably arranged in the housing, however, not centrally, but rather decentrally, being arranged on one side directly on the inside wall of the housing is and on the other side a single wing carries, which performs a pivoting movement when the axis rotates.
  • This known damping device also flows when the axis rotates, the fluid moves from the first to the second chamber.
  • the two known rotary dampers have proven. They work reliably in normal operation. in the The latter, for example, becomes related to a toilet lid manually set to close initially, whereupon it closes by itself slowly, until it goes to circulation comes to the associated toilet seat. If so far was necessary to quickly close the toilet lid you also push it down. With the corresponding The toilet seats and / or covers were also able to exert force equally can be opened quickly.
  • the invention has for its object the longevity by increasing dampers that are not just normal damping operation are exposed, but also additional Subject to stress.
  • the task is performed by a generic one Damping device solved, which is marked by at least one valve that is in normal damping mode is closed and that between the first and the second chamber an additional flow in both directions creates second flow path when the pressure difference reached a certain value between the chambers.
  • the invention is based on the knowledge that the The rotary damper does not leak due to aging the seals is due, but rather to the extremely high pressures that occur in the chambers when the Damping device is operated with great effort. Such high pressures occur, for example, when one sits on a toilet lid that is not yet closed. Due to the rapid movement of the wing or wings through the Damping fluid cannot "quickly" inside the housing flow enough "from the first to the second chamber. It there is a risk of leakage of fluid from the Casing. This affects in particular the position where the axis comes out of the housing. Doing it turned out that a small diameter of the Sealing the axis is much better than a large diameter.
  • the invention alleviates the problem of leakage simple way.
  • the valve is in normal damping mode closed. It only opens when the pressure difference a critical between the first and the second chamber Value reached. So the valve is set so that the damping device in unchanged - proven - Way performs its damping function and - as just now mentioned - only at a critical pressure below the pressure leading to an exit of the damping fluid, triggers. This not only leads to protection of the burdened Seals, but also leads to a meaningful Extension of the damping device in such a way that if for example a quick actuation of the toilet seat or the toilet lid is desired, this operation without considerable resistance is feasible.
  • rotary dampers have been increasingly used used, which have particularly small dimensions.
  • An essential one Further development of the invention is characterized in that the valve is integrated in the axis.
  • the valve can be designed as a ball valve be, the ball in a hole in the axis sitting. As a rule, one becomes the damping device according to the invention make of plastic so that the hole is relatively easy to insert into the axis.
  • a particularly favorable construction results if the ball has a maximum of half its diameter closes the second flow path. Then it offers one sufficiently large attack surface to be moved.
  • valve body is not must necessarily be designed as a ball, if so represents a particularly simple and advantageous embodiment.
  • a cylindrical one is also conceivable Valve body with a tapered end section.
  • the valve is preferably preloaded via a screw that can be screwed into the front of the axle.
  • the damping device can therefore depend on Field of application to be adapted. The lower the preload is selected, the more "the valve triggers". With regard on a toilet lid to be damped, this means that the Manual cover with relatively little effort is closable.
  • An advantageous embodiment of the invention is characterized in that the second flow path is transverse goes through the axis.
  • the second flow path can, for example be designed as a hole in normal operation through the valve body - in the case of a ball valve the ball - is closed. At a certain pressure the valve body is pushed to the side, for example in the axial direction.
  • the opening characteristics of the Valve different in both directions of rotation of the axis. This can be achieved, for example, in that the formed inlet of the second flow path is made larger is as the outlet or vice versa. With this constructively simple measure can be caused to the valve triggers in one direction rather than the opposite Direction. With reference to use in connection with Toilet lids would mean, for example, lifting of the toilet lid is easier than lowering, because that Valve triggers faster when lifting the toilet lid. in the a similar effect can be achieved by that the attack surfaces exposed to the damping fluid are inclined to different degrees.
  • the invention Damping device is versatile, wherever two swivel or rotatably connected components against each other in their swivel or rotary motion should be damped.
  • An advantageous one The area of application is sanitary engineering.
  • the damping device preferably has a wing assigned closable passage for the passage of the Damping fluid that opens when the pressure difference between the first and the second chamber a certain one second value reached, the first value being greater than the second value.
  • Such a damping device is already designed to be essentially only one Dampens direction while moving the other in the other direction parts pivotable or rotatable relative to each other.
  • One of the main things that dampens a toilet lid provide in the closing direction so that the lid does not fit on the Toilet seat beats.
  • opening the lid should be possible be possible without damping. Still are in both Directions of transfer of damping fluid from the first set limits in the second chamber. This is where the damping device comes into play one that only opens when a value that is above the normal damping value - in Damping direction - or "opening value" - in the opening direction - lies.
  • the damping device according to FIG. 1 has a housing 1 with at its rear end a housing cover 2 can be closed tightly. On the front Bottom of the case is integrally elongated Threaded section 3 formed by an opening of a (not shown) toilet bowl pluggable and from the bottom the toilet bowl is screwable.
  • the damping device 1 is used to dampen toilet seats and / or lids used.
  • an axis is rotatably arranged, such as it explained in more detail later in connection with Figure 3 becomes.
  • the axle is mounted in the cover 2 and occurs with a first axle section 4 from the housing.
  • the intercept 4 is profiled and engages when assembled a toilet seat or a toilet lid with a positive fit. equally Of course, a frictional connection is also conceivable Connection.
  • Figure 2 shows the damping device according to the invention in a rear view, and for better illustration without Cover.
  • the axis 5 already mentioned in FIG. 1 is arranged decentrally and carries an integral wing 6.
  • the wing 6 divides the interior of the housing into a first chamber 7 and a second chamber 8.
  • the inner contour 11 of the wing 6 opposite Housing is "wave-shaped". In the starting position is the distance between the wing and the case relatively large and thus the damping relatively small. It requires therefore only a small amount of force is required to pull the wing 6 in To pivot towards 9. About in the middle of the direction of movement of the wing 6, the damping effect is greatest, since the distance between the inner contour 11 and the wing 6 is the smallest is. In the direction of the end position of the wing Distance again larger.
  • FIG. 3 in which the axle wing unit is shown on an enlarged scale.
  • Axis 5 has a through opening 12 formed through it a ball 13 guided in the axis is closed.
  • the Ball 13 is biased by a spring 14, the degree the bias is adjustable via a screw 15, the is in threaded engagement with axis 5.
  • the passage 12 creates a connection between the Chamber 7 and chamber 8 (see Figure 2).
  • the passage 12 is released when the pressure difference between the chamber 7 and the chamber 8 reached a certain value.
  • the Tripping characteristics can include the preload the ball 13 can be adjusted. Of essential influence is also the size of the sphere and the degree of coverage of the passage 12. It is proposed that the ball 13 the passage 12 at most with half of its diameter covers to attack the damping fluid on the domed To allow outer surface of the ball.
  • flutter valve 16 In the wing itself there is a so-called flutter valve 16 formed that a bore 17 and a dashed line Lamella 18 has a rivet 19 with the Wing is connected.
  • the flutter valve 16 is only in one Direction of flow, whereby in connection with a Toilet seat or a toilet lid will make the arrangement so that the fluid when opening, which is regularly damped is dispensable, is flowed through.
  • the opening 17 through the slat 18 closed.
  • the invention also in connection with a flutter valve or a comparable valve is applicable. It exists namely when opening the toilet lid or toilet seat quite the risk of overload. This is where the invention comes into play on.
  • the spring preload is a matter of course chosen so that the passage 12 only at a higher Pressure when the flap valve is opened.
