Description

Cover for waste from a waste container, in particular for a vehicle

The invention relates to a waste lid of a waste container, in particular for a vehicle, with particular preference for an airplane, according to the preamble of claim 1.

It is generally known, for example, a waste container that is integrated in a console washbasin, which is mounted on a vehicle, in particular on an airplane, in a train car or on a ship. In a known arrangement of this type, the waste lid is pivotally supported on a pivot shaft in the upper edge area of the container opening, and can be manually folded inwardly against the force of a device recoil to release an entry hole. The recoil device is disposed between a fixed position support point and a support point in the waste lid, used with a rechargeable energy accumulator, in particular a recoil spring. By manually operating the waste lid, the energy accumulator is charged or the recoil spring is tensioned in the open position. After releasing the waste cover, it is automatically repositioned using the recoil device from the open position in the initial position as the closed position. The arrangement is sized in such a way that in the closed position the energy accumulator is not yet fully discharged or a recoil spring is not yet fully tensioned, so that the waste lid is supported from below against the edge of the opening of the container under a certain initial tension.

The known waste cover must be operated in this way by a hand pressure from above on the previously tensioned waste cover by means of a spring. Due to the forced contact of this type with the hand or even with the residue itself held by the hand, a cover for waste of this type is generally dirty and smeared even after a brief use, so that on the one hand it is visually little attractive and also presents hygienic problems.

From EP1600373A2 a waste cover is already known, which has a recoil device with a rechargeable energy accumulator in connection with a controllable electric motor. Specifically, the electric motor works in this case as a shock absorber. A rigid lever is provided here as a device for opening the waste lid. Therefore, in the powerless state of the electric motor, rattling noises cannot be silenced or reduced safely for operation. In addition, a simple manual operation of the cover is not possible in case of an electric motor failure.

Therefore, the object of the invention is to prepare a cover for waste in which movements that generate noise, such as vibrations and oscillations, and that function safely also in the event of an electric motor failure of a motor are reduced. opening device

This objective is met with the characteristics of claim 1.

According to claim 1, an opening device is provided with at least one adjustment element that transmits the movement between a fixed position clamp and a clamp in the waste lid. The opening device has an electric motor that can be controlled in a direction of rotation corresponding to the opening direction of the waste cover for a movement of the adjustment element and thereby of the waste cover to its open position. The electric motor is sized for this purpose with enough force to overpress the recoil device and charge the energy accumulator inside. In this way the opening of the container is left open to dispose of the waste. Then the electric motor control is disconnected. In this state without electric motor current, its secondary shaft coupled with at least one adjustment element can rotate in the opposite direction through the discharge of the energy accumulator, such that the waste cover is automatically returned from the open position to the closed position, as well as to the adjustment element in the corresponding initial position.

It is also provided that the waste lid is supported and articulated by way of a unilateral lever, where it can be opened downwards towards the inside of the container hole. In this way, the opening device and the recoil device are arranged in an interior area of the container under the waste lid, so that for a corresponding dimensioning a suitable kinematics is obtained. As the adjustment element, a tension belt is used according to the invention, connected on one side with the fastener in the waste cover and on the other hand a winding coil connected to the secondary shaft of the electric motor. When the electric motor is operated, the traction belt is wound for a traction opening of the waste cover, and when the electric motor is not activated, it is unwound again by means of the recoil device to an initial tensioned position. A particular advantage of the traction belt is that the waste lid can also be opened directly at any time by hand, for example in the event of a failure of the opening device, where the traction belt is only discharged and form loops. The automatic return to the closed position of the waste lid is not affected by this, since the tension belt is only transferred back to a tensioned position.

The aforementioned reverse rotation capacity of the secondary shaft of the electric motor coupled with the adjustment element in the no-current state is easily achieved in accordance with the invention by making the electric motor present an internal inhibition against the reverse rotation so small that the The electric motor can be turned in the reverse direction by the recoil force of the charged energy accumulator to the closed position of the lid.

Also, according to the invention, a combination of a recoil spring and a shock absorber acting parallel to it and with proportional speed is provided in the recoil device as a rechargeable energy accumulator. By means of this spring-damper combination, a quiet and uniform pleasant recoil movement of the waste lid is achieved. When only a recoil spring without a shock absorber is used, this can result in the movement of the waste cover slightly rising above the support edge and rattling for movements conditioned by operation, such as vibrations and oscillations. The effect of the shock absorber prevents rattling of this type. The recoil spring and the shock absorber are integrated in a cylinder-piston unit as a spring-shock absorber unit, which is hingedly supported on one side at the point of support of the waste cover and on the other hand in the fixed position of support in the waste container. In this way, a compact unit is advantageously obtained that requires little assembly space and works without maintenance with proper operation.

To open the lid for waste it is no longer necessary according to the invention to open it with the hand against the force of the recoil device, but the opening occurs automatically by means of an electric motor control. The control can be produced simply by means of a button in the vicinity of the waste cover, which activates a time element during a certain control time for a power supply of the electric motor. Alternatively to a manually operated button, other known control elements, such as contactless sensors, motion sensors, light bars, foot switches, etc., can also be used for an electric motor control.

Advantageously, the waste lid is thus generally open before the waste is discarded, so that it is not rubbed on the waste lid as usual until now, resulting in dirt and hygienic problems. It is obvious that comfortable and simple use is another additional advantage.

In a technically advantageous arrangement suitable for mounting according to claim 2, the electric motor is fixed with the axis parallel to the axis of folding on a stand as a fixed support as well as the fixed position support point of the recoil device in a inner area of the container below the axis of despondency. The support position of the recoil device in the waste lid as well as the clamping of the opening device in the waste lid are thus displaced towards the center of the waste lid, thereby achieving an easily controllable motion kinematics. .

According to claim 3, an activatable control unit is connected to the electric motor, through which the power supply of the electric motor can be connected for a predetermined time corresponding to a time for the opening of the waste cover as well as an additional time to keep the waste lid open.

In a particularly preferred embodiment according to claim 4, a proximity sensor is integrated in the lid element and / or in the control unit of the waste lid, which in the case of an approximation of an object, in particular in case of approximation With one hand, it generates an approach signal for immediate or non-immediate excitation of the opening device. In particular, according to claim 5, the approach signal must be conducted to a titration and control unit, which from a predefined approach distance sends the electric motor of the opening device according to a given assigned approach signal.

In a specific improvement according to claim 6, the proximity sensor is a capacitive sensor, wherein the lid element of the waste lid itself is formed as a condenser plate, whereby its connection with the device with the titration unit and connected control is preferably produced through the hinge of the folding shaft.

Especially suitable is the arrangement according to the invention of the waste container with its waste lid as a component of a console washbasin for a vehicle, in particular for an airplane or for a train car or for a ship. In these applications it is also especially advantageous that the waste cover is always closed, in particular also when the power supply is missing and / or in case of failure of the electric motor, so that in any case the closing security is given, and from the waste container there is no risk of fire or unpleasant discomfort from bad odors. In addition, a high level of hygiene is guaranteed by a contactless drive.

The invention is described in more detail on the basis of a drawing.

In fig. 1 shows a console washbasin 1 with a washbasin 2 and a waste lid 3 fixed next to it, below which is located (not more explicitly represented) a waste container.

In fig. 2, a perspective representation is shown on the waste lid 3 from the inside face of the console washbasin, with a visual orientation tilted upwards. From it, a recoil device must be deduced in the form of a spring-damping unit 4, in which a spring element is integrated as a rechargeable energy accumulator as well as a parallel and speed-dependent damping element. The spring-damper unit 4 is hingedly fixed on one side to a fixed support point 5 in the console washbasin 1 and on the other hand to a support point 6 of the waste lid 3 near the pivot axis. 7.

In addition, an opening device 8 with an electric motor 9 is shown, which is fixed parallel to the axis to the axis of abatement 7 to a stand 10, and in which secondary shaft a winding coil 11 is arranged. Between the winding coil 11 and a fastener 12 on the underside of the lid runs a tension belt 13, which is held tensioned in the closed position shown of the waste lid 3.

In the corresponding lateral representation according to fig. 3, the waste cover 3 is shown again in the closed position, as well as the spring-damper unit 4, the winding coil 11 in the electric motor 9, as well as the tension belt 13. A unit is also shown schematically of evaluation and control 14 which is connected on the one hand with the electric motor 9 through an electrical connection 15 and with the waste cover 3 through another electrical connection 15 ', which in this case is part, shaped of condenser plate, of a proximity sensor 16 that acts without contact. The proximity sensor 16 delivers an approach signal to the evaluation and control unit 14 at the approach of the hand 17.

The operation of the arrangement shown in fig. 2 and in fig. 3 considering fig. 4 to 9:

At an approach of hand 17 to the waste cover 3 up to a predetermined distance, the evaluation and control unit 14 sends the electric motor 9 for a predetermined time. In this way the tension belt 13 is wound, whereby the waste cover 3 is brought to its open position, which is shown in fig. 4 and 5. The waste lid 3 thus leaves an opening of the container 18 free to discard the waste. At the same time, together with the opening of the lid, the recoil spring is tensioned in the spring-damper unit 4, which is shortened in this way.

In fig. 6 and 7 shows the operating state, in which the spring-damper unit 4 returns to the waste cover 3 back to its initial position or closed position, where approximately halfway has been traveled here. For this reverse movement, the evaluation and control unit 14 has disconnected the power supply to the electric motor 9 after a predetermined control time has elapsed. The electric motor 9 is sized with a force such that it opens the waste cover 3 against the recoil force of the spring-damper unit 4 with an initial tension of the recoil spring, but which in the state without current only has an internal inhibition against the inverse rotation so small that an inverse rotation occurs and thereby a recoil displacement of the waste cover 3 through the spring-damper unit 4.

Once the waste lid 3 has been completely closed, the closed position shown in fig. 2 and 3

In fig. 2 to 7 the automatic opening of the waste cover in conjunction with the automatic recoil has been shown and described. In fig. 8 and 9 instead represents the emergency opening, for example, in case of failure of the proximity sensor 16 and / or of the electric motor 9.

As can be deduced from fig. 9, the waste lid 3 can be pushed down and opened by hand 17 as before according to the state of the art. By means of this movement, only the tension belt 13 is discharged and placed in one or more loops, as shown in fig. 8. At the same time, by means of the opening movement with the hand 17, the recoil spring in the spring-damper unit 4 is tensioned. After discarding the residue and releasing the open waste cover 3, it is moved back again. to the closed position by means of the spring-damper unit 4, whereby the tension belt 13 is again tensioned according to fig. 2.
