Abstract

The ejector (1) has a first ejector lever (2), which can be driven by an electric drive unit, especially an electric motor, an additional ejector lever (3) interspaced from the first ejector lever and mechanically coupled to it in such a manner that when the first ejector lever is driven by the drive unit the additional ejector lever is also displaced. The movement is detected by a sensor, whereupon the drive unit is activated by a control and/or regulating device. An independent claim is also included for an item of furniture with a carcass and an ejector.

Description

The present invention relates to an extruder for discharging a movable furniture portion from a closed end position of a furniture body provided with a first push lever that can be operated by an electric drive device (particularly, an electric motor).

  In particular, in a movable furniture part that is very wide (particularly a drawer part that is very wide), a general-purpose extruder is generally arranged at the center of the furniture body. This is because an improper force acts on the movable furniture part in a biased arrangement (risk of tilting).

In general-purpose extruders, an electric drive is activated when an attractive force or pushing force is applied to the push lever, and the movable furniture part is ejected from its closed end position. It is desirable to do. In order to complete the operation of such a device and enable a push-induced operation, the moving furniture part must be furniture even if it is in its closed position. A free space that can move a little into the body is needed. It is in this very wide range of movable furniture that the problem with the touch latch actuator is that the pusher described above is centrally located. This is because it is impossible for all users to apply a force necessary for releasing the acting force to the central portion of the movable furniture portion.

  Regardless of whether the general-purpose extruder has a touch-latch actuator, if the movable furniture is very wide, it is even optimal for the force application that the extruder is centrally located. There wasn't. For example, it is the rear wall of the drawer, but it is in the central region of the movable furniture that relatively large deformation occurs in the movable furniture.

  Of course, the above-mentioned two problems can be avoided by arranging two extruders in the vicinity of both side walls of the furniture body. Unfortunately, this solution is not costly desirable.

Accordingly, it is an object of the present invention to develop a single-purpose extruder in a universal form that solves at least one of the aforementioned problems.

  This object is achieved by an extruder with the features of claim 1.

  Providing a second push lever mechanically coupled to the first push lever eliminates the need to place two separate pushers in the furniture body. At the same time, the problem of the action of biased release force on the movable furniture part is eliminated. This is because, in the extruder according to the first aspect, the release force is applied to the edge of the movable furniture portion, and the deformation of the movable furniture portion is small.

  When the pusher is equipped with a touch latch actuator, the problem of the release force that is difficult but can only be detected at the center position is detected by the sensor that monitors the movement of the first pusher lever. This can be solved if the second pushing lever is mechanically connected to the first pushing lever.

  This makes it possible to detect the release force applied to the movable furniture portion near both side walls.

  Advantageously, the two embodiments described above allow attachment to the rear wall or side wall of the furniture body and avoid mounting on the transport.

  One particularly simple embodiment for this mechanical connection is in the form of a bar.

  Theoretically, however, the use of other more complex devices (eg lever devices) for the mechanical connection of the two extrusion levers is also envisaged.

  The invention also includes furniture with a furniture body and an extruder according to one of the embodiments described above. Here, the first push lever and the second push lever are disposed on both side walls of the furniture body.

  Further advantages and details of the invention will become apparent from the drawings and the description of the drawings.

  FIG. 1 illustrates a furniture 8 having a furniture body 5 and three furniture parts 9 in the form of drawers according to one embodiment of the present invention. These furniture portions 9 are movably mounted in the furniture body 5. However, the present invention can also be used in a movable furniture portion in the form of a furniture door.

  FIG. 2 illustrates the furniture 8 shown in FIG. 1 with the rear wall removed and the movable furniture portion 9 partially pulled out from the furniture body 5.

  Each of the lower two movable furniture parts 9 is equipped with one extruder 1 according to one embodiment of the present invention. In the lowermost movable furniture portion 9, the first push lever 2 is installed on the side wall 6, and the second push lever 3 is installed on the side wall 7. This arrangement of the central movable furniture part 9 is the opposite.

  Each extruder 1 is provided with a housing 10. The electric drive device, the open-loop or closed-loop control device for the drive device, the gear device, and a sensor (for example, a rotational potentiometer) for detecting the movement of the first push lever are housed.

  3 and 4 are detailed views of the furniture 8 shown in FIGS.

  FIG. 5a illustrates an extruder 1 with a first extrusion lever 2 of the present invention. In this embodiment, the winding member 12 is attached to the rod 4 in a state of being fixed in a rotational manner. The winding member 12 is designed and arranged with respect to the first pushing lever 2 so that it rotates together with the first pushing lever with a slight rotation of the rod body 4. This structure is important when the operation of the extruder 1 is canceled by moving the second extrusion lever 3.

  In actual use, if the movable furniture portion 9 is pushed by the side of the furniture main body 7 on which the second pushing lever 3 is mounted and pushed into the furniture main body 8, the movement is wound by the rod body 4. It is transmitted to the insertion member 12 and further transmitted to the first extrusion lever 2. The first pushing lever 2 is connected to a rotational potentiometer by a gear 13. After this movement is detected by the rotary potentiometer, the electric drive device of the extruder 1 is activated and the movable furniture portion 9 is discharged.

  FIG. 5 b illustrates the mounting of the rod 4 of the extruder 1 on the member 11. This mounting is a floating mounting configuration. That is, the rod 4 can be rotated without being disturbed by the locking of the electric drive device. Of course, the first push lever 2 also has a certain amount of play and can be moved a little by the gear without being locked. Such a design is disclosed, for example, in the description of the specification relating to FIG. 17 and the figure of AT413472B. Therefore, this structure will not be described further.
