Description

Piece of furniture with opener

The present invention relates to a piece of furniture with a cabinet door or drawer opener according to the preamble of claim 1.

Such a piece of furniture has a body which is formed with at least two wall parts and at least one cupboard door and / or drawer.

Pieces of furniture with opening devices are known in that the device for opening a door or a drawer takes up a not negligible part of the volume in the cabinet, limits the width according to which, for example, a drawer can be provided in the body or hinder the storage volume.

The object of the present invention is therefore to solve these disadvantages of the prior art. According to the invention, the object is achieved by a piece of furniture with the characterizing features of claim 1 and by an opener with the features of claim 4.

Preferred embodiments are specified in the dependent claims, the description and in the drawings. The piece of furniture according to the invention is characterized in that at least one bore is provided in at least one wall part, of which at least one bore has an opening which faces the cabinet door and / or drawer and that an opener is provided in the bore which is connected to a Positioning means or actuating body is provided, which is designed to move the cabinet door and / or the drawer at least partially out of a closed position when the opener is actuated.

The bore can in particular be a partial bore, which can be perceived as a depression from one side of the piece of furniture and cannot be seen from the other side of the wall. In any case, the invention is implemented when a piece of furniture is provided with a hole for (completely) receiving an opener, which is used to move an opening closure, such as a door or a drawer or a drawer pull for a closable and / or openable opener. is provided, which provides the opening closure between an open and a closed position, preferably without the application of force by the user, but by a drive.

The force required to relocate should relate in particular to an effective relocation of the opening closure (door, drawer pull-out, etc.). A possible application of force to an opening mechanism to activate it should Activation should by definition also be possible if the position of the opening closure is provided by the opener according to the invention without the user having to exert any force. This effect of force is not recorded by the powerless relocation of the door, since it only activates the mechanism but does not do the actual lifting work on the door.

According to the present invention, the opener is at least completely provided in a wall of the body of the furniture part if at least the actuating means in its rest position and the drive are provided within the wall. The opener is preferably completely accommodated in the wall when the housing is present within the wall, a small protrusion, for example with a retaining edge, being able to overlap and / or protrude over the bores.

The opener according to the invention can be realized in that it is designed with a housing and / or an actuating body (11) (which is arranged in the housing) and which can be moved relative to the housing between a rest position and a working position, in which the actuating body can protrude from the housing and the cabinet door or a drawer extension of the drawer is displaced, whereby the actuating body can be operatively connected to an electrical or mechanical drive by means of which the actuating body can be moved, and / or wherein the drive can be connected to an energy store.

According to a basic idea of the present invention, a piece of furniture with a cupboard door or drawer opener is specified, which can be automatically shifted between the rest position and the working position after a corresponding signal or impulse has been provided by a user. In principle, the pulse or the signal can be provided, in particular electronically, by pressing a trigger that is coupled to the drive. As an alternative or in addition to this, a signal for shifting the position of the opener according to the invention can be provided by means, for example by radio and / or via proximity sensors, which enable the mechanism to be actuated without contact. Insofar as this is necessary for the technical processing of the pulse or signal, the opener according to the invention can have a corresponding signal or pulse processing unit which is operatively connected to the drive and can be designed to drive the drive on the basis of the pulse or signal to operate.

According to the invention, it can be advantageous that the actuating body can be shifted between two defined positions, in particular the rest position and the working position. For this purpose, it can be advantageous that the control of the drive is adapted to limit actuation of the drive and thus a displacement of the actuating body to the displacement distance / distance between the rest position and the working position. This can prevent excessive strain on the material due to unnecessary force. According to the invention, the housing for the actuating body can be completely or partially closed. This allows the opener technology to be exchanged particularly easily. However, the housing for the opener can, for example, be drilled through a hole in the body material of a cabinet or drawer or the door or the drawer extension (if the opener is arranged accordingly in the door or the drawer extension instead of in the body to be worn out) ) be provided in whole or in part.

In principle, the opener can be arranged both in the cavity to be closed (cupboard, drawer, room) and in the closure element / opening cover, such as the door or the drawer pull-out. The rest position of the actuating body is provided according to the invention in such a way that a door, a drawer pull-out or another opening cover can close the opening properly, preferably flush. For this purpose, the actuating body can either make contact with the opening cover in its rest position or be in free contact with it.

In the working position, the actuating body of the opening cover can be positioned in such a way that it at least partially from the position in which it closes the opening in the direction of an open position, for example a position in which access through the opening into the interior allows is, is moved. Particularly preferably, the deflection of the opening cover from an opening-closing position can be provided by the actuating body at least in such a way that reaching behind the door or the drawer pull-out is made possible.

This can be conducive to particularly easy opening of a door or a drawer pull out by dog. In the working position of the actuating body, an opening cover should at least be shifted out of the closed, opening-covering position such that a further facilitated dog-like shifting of the opening cover into an even further open position is made possible.

The drive according to the invention is realized at least when means are provided which are operatively connected to an energy store which enables movement, in particular a rotational movement of the drive, energy being used up by the drive from the energy store. In this case, the energy store and drive can be provided both as two separate units and as a common unit.

According to the present invention, a combination of energy store and drive in the form of a spring, which only transmits its positional energy present in a tensioned state to an actuating body, is preferably excluded his. According to the invention, a spring element should neither form the drive nor a combination of drive and energy store. According to the invention, a spring does not represent a drive which consumes the energy of an energy store when an actuating body is displaced, a drive can therefore in particular represent a complex component.

It is preferably provided that a transmission element, in particular a transmission, is provided between the drive and the actuating body, which can be brought into engagement with the actuating body or an extension thereof. In principle, such a transmission can be provided with at least one, preferably two, motion-transmitting elements, in particular gear wheels. These can move the actuating body directly or via an extension, for example in the form of a toothed rack, between the working position and the rest position. The rack can be operatively connected to the actuating body and can be in engagement with the gear.

It is particularly preferably provided that the energy store is an electrochemical energy store. In principle, the energy store can be of any design and, for example, energy can be provided in the form of spring tension, position energy or in some other way. According to the invention, however, it is particularly preferred that the energy is provided electrochemically, in particular in the form of a battery or rechargeable batteries, which are preferably interchangeable with and connected to the drive. An electrochemical energy source also means, for example, a solar cell with or without an intermediate store for electricity in the form of an energy storage cell, such as a lithium battery, and thus also includes photovoltaic solutions for supplying energy to the drive.

According to an expedient development of the present invention, it is provided that the cabinet door or drawer opener has an actuating element, by means of which the drive can be activated and / or deactivated. The actuating element can provide feedback of an action by a user with the cabinet door or drawer opener and, in particular through the feedback, can actuate the opener mechanism, in particular the drive. The actuating element can be a spring-mounted switch, for example, which is operatively connected to an activation unit of the drive. However, radio and / or other sensory devices (for example a motion sensor, proximity sensor, touch sensor, in particular a pushbutton element, etc.), which detect, for example, a touch, a movement or a push of a button (preferably remote), can be provided for the drive to set in motion after appropriate actuation of the device and to cause a displacement of the actuating body.

Should this be necessary for the respective individual device, control elements can be provided between the drive and the actuating element, or the other sensory devices for actuating the drive, which control the respective interaction of the user with the actuating element or the sensory device in a corresponding signal translated for the drive.

According to a preferred development of the present invention, it is provided that the actuating element is arranged in a front region of the actuating body, which can be contacted with the door or the drawer pull in the operating state. According to such an embodiment, a signal to the drive can be provided that the latter is activated and activated, for example by a pressure on the opening lock / opening cover, in particular the door or the drawer pull-out, which can be in contact with the actuating element is set in motion, whereby a displacement of the actuating body between the rest position and the working position is provided, preferably out of the rest position. A displacement of the actuating body from the working position into the rest position initiated by such a pulse / signal / switch actuation can be expedient, for example, when the opening cover, in particular the door or the drawer pull-out, is provided with a restoring force in a closed position, as a result of which Opening cover is movable from an open position to an opening covering position. Such an independent closing movement of the opening cover can strike / contact the actuating element in a front region of the actuating body and initiate a displacement of the actuating body into its rest position by actuating the actuating element. By means of the drive of the opener according to the invention, a displacement of the opening cover into the rest position can be provided in a guided manner by the drive, whereby an accompanying closing of the opening cover can be provided lying on the actuating element / body. This can prevent the opening cover from hitting a frame area of the opening to be covered.

It can particularly preferably be provided that the actuating body is operatively connected to a damper which is arranged to absorb a kinetic energy of a closing door or a closing drawer pull and to dampen it in relation to the cabinet door or drawer opener. For this purpose, the damper can be arranged, for example, in a front region of the actuating body, in particular on an end face which faces an opening cover. As a result, the damper can absorb the energy of, for example, a spring-loaded door, which spring is relocated to a closed position in a relaxing manner, which can be beneficial to the durability or the service life of the components of the cabinet door or drawer opener.

Particularly preferably, the actuating element and the damper can both in the front region of the actuating body, which is the opening cover turns is to be arranged. The arrangement in this case is particularly preferred (door) actuating element damper actuating body or (door) actuating element actuating body damper, whereby both the activation of the drive by actuating the actuating element and the damping function of the steamer are provided particularly effectively can.

According to a further development of the present invention, it is preferred that an electronic control element is provided which is connected to the drive in a drive-controlling manner and / or is designed to at least activate the drive on the basis of an actuation of the actuation element. In principle, the actuating element already described can be designed such that actuation leads directly to activation of the drive. All technically necessary means, in particular a possible control unit for actuating the drive, can be provided in the actuating element.

However, such an electronic control element can also be provided as a separate unit, preferably in or on the housing of the cabinet door or drawer opener. Regardless of the solution to the control question of the drive, the control element can be designed on the one hand with means to detect an actuation of the actuation element and on the other hand (and / or) be provided with means which control the drive, in particular an electrical drive - drive, enable. The electronic control element can in particular help to provide a path limitation for the displacement of the actuating body between its rest position and at least one working position.

To limit the path between the rest position and the working position, programming of the control element can be provided which provides a predefined movement sequence, in particular a predefined number of revolutions of the drive or a stroke path for the actuating body. In addition io

or alternatively, a mechanical resistance, for example in the form of a stop between the actuating element and the housing or an extension of the actuating element and the housing, can be provided. Particularly preferably, both the mechanical resistance and (and / or) the electronic control element can be adjusted, as a result of which the stroke path of the actuating body, that is to say the path between the rest position and the working position, can be adapted as required.

According to an expedient development of the present invention, it is provided that the drive and / or the electronic control element are provided with time-determining means, and the actuating body is designed automatically from the extended position to the retracted position after a predefined time method. The time determination means can comprise an electrically controlled quartz element, a processor-controlled time cycle or some other means (also mechanical, e.g. egg timer) for determining a predefined time unit. As a result, the actuating body should preferably be able to be returned independently from its working position to its rest position after a predefined time. For this purpose, the time determination means are operatively connected to the control and / or the drive as required or are an integral part thereof.

For this purpose, it may be necessary for the drive to be controlled accordingly in order to bring about a displacement of the actuating body from the working position into the rest position. This shifting back into the rest position of the actuating body can thus take place without the influence of a user or a door on the actuating body. This can prevent damage to the actuating body or a user getting caught on the actuating body.

In principle, the actuating body can also be returned to its rest position without the action of a door or other opening closure, for example in which the actuating element is activated manually and thereby itself opened opening (door, drawer, etc.) the actuating body can be shifted in its position.

An expedient development of the present invention is that the housing is at least partially provided as a guide sleeve, against which the actuating body can be moved coaxially when the housing is extended and retracted. According to the invention, the actuating body and the housing surrounding the actuating body can have any shape. However, it is particularly expedient that the actuating body has an approximately cylindrical, but at least elongated shape, one end of which is provided along its longitudinal axis in a housing, preferably a guide sleeve, and the other end of which is an opening closure (door, Drawer, drawer pull-out, ...) can be moved out of the housing.

A housing, in particular a guide sleeve, can be provided coaxially to this longitudinal direction, with respect to which the actuating body can be displaced and can thus be moved out of this housing and into it. In principle, it is advantageous if the entire technology for actuating the actuating body is arranged in the guide sleeve. As a result, the entire opener according to the invention can be used in a simple bore, which is provided, for example, in an end face of a frame element of a door or a drawer.

In principle, it is advantageous that the cabinet door or drawer opener can be provided in a housing wall of a body, the body being limited, for example, by the door or the drawer pull-out opening or closing at least on one side. The housing wall of a body can be, for example, a door passage of a door, the body of a wall cupboard or base cabinet or the body of a drawer or a drawer system. In the case of such devices, the opening closure, for example the door or the drawer pull-out, is at least partially in the closed state against a frame which is designed as part of the housing wall. In this contact area, the opener according to the invention can be provided, for example, on the housing wall or within the housing wall, for example in one or more bores.

According to a preferred development of the present invention, it is provided that the housing is constructed in at least two parts, the actuating body being provided in a first housing part and the drive being provided in at least a second housing part. In principle, the opener can be designed in several parts, at least in two parts, the actuating body with the housing, for example a pin or an ejection stamp, being arranged in a bore which is coaxial with the actuating body and the opening of which is in the direction of the opening closure, for example a door or shows a drawer pull.

According to a development of the invention, it is particularly preferred that the at least two parts of the housing are operatively connected to one another in the at least two openings in the housing wall. Due to the multi-part construction of the housing, it can be fixed in a particularly reliable manner in or on the body, without additional fixing means between the housing part and the opener according to the invention being necessary. A detachable or non-detachable connection, in particular a snap or snap connection between the individual housing parts, is particularly preferably provided. In particular when individual housing parts are provided in different bores, which preferably have openings in different spatial directions, this can enable the opener according to the invention to be fixed, in particular without further damage to the outer body layer by additional fastening means, such as screws, nails or rivets, for example. For this purpose, the individual housing parts can be operatively connected to one another and can be provided in communicating openings or in a common opening in the body.

The method according to the invention is characterized in that a cupboard door or drawer opener according to one of claims 1 to 14, which is located on a corresponding cupboard door or a corresponding drawer or another opening lock, is triggered and the cupboard door or drawer opener detects the Cabinet door or drawer operated by an operating body the cabinet door or drawer opener is relocated to the cabinet door or drawer pull-out.

The method according to the invention is implemented at least when a cabinet door or drawer opener according to the invention is activated by appropriate actuation in such a way that it moves an opening cover, for example a cabinet door or a drawer pull-out, from a first position into a second position by means of an actuating body. wherein the first position is preferably a position in which the opening cover covers the opening and the second position is a position in which the opening cover at least partially opens the opening, that is to say the opening cover is partially opened.

It is particularly preferably provided that the housing is constructed in at least two parts and / or the actuating body is provided in a first housing part and the drive is provided in at least a second housing part.

Each housing part can consist of one or more elements, such as a receiving space and an associated cover.

FIG. 1 shows a preferred embodiment of the opener 10 according to the invention, which in this embodiment can be provided with (at least) two separate housing parts 12, 12 '. In the first of the housing parts 12, the preferably elongate actuating body 11 is arranged to be movable along its longitudinal axis. In The second housing part can be provided with at least one of drive 16 and / or an energy source in the form of a battery 17. In addition, at least one toothed wheel 14, which can also be designed as a worm wheel 15, can be provided in the second housing part. Preferably, a gear is provided from at least one gear 14, 15, preferably from a worm gear 15 and a gear 14. In principle, the components of the opener can also be distributed to the housing parts in a different way if it is not a common housing.

The gear (arrangement), which consists of at least one gear, preferably a worm gear, can transmit the movement of the drive 16 to the actuating body 11. For this purpose, the actuating body 11 can be designed with transmission means, which can transmit a movement of the drive 16 or of the gear 14, 15 to the actuating body 11. It can preferably be a toothing on the outer circumference of the actuating body 11 or a separate toothed rack 13 which is approximately coaxial with the actuating body

12 arranged and / or can be at least partially movable together with the actuating body 12 between a rest position within the housing 12 and a working position outside the housing 12.

1 shows the actuating body 11 in an extended position, which can represent a working position. In this, the rack 13 is at least partially extended out of the housing. Depending on how the proportions of the actuator body 1 1 and gear rack 13 are proportional, the rack

13 can also be provided in the working position of the actuating body 12 within the housing, since the length of the actuating body 11 can in itself be sufficient to be extended from the rest position into the working position without the toothed rack 13 leaving the housing 12 got to. The housing 12 can accommodate the rack 13 and the actuating body 11 at least in the rest position (completely). In at least one area of the housing 12 of the actuating body 11, an area is provided in which the actuating body 12 or the toothed rack 13 can interact with the gear 14, 15.

Although the opener 10 is provided here with two housing parts 12, 12 ', a, preferably form-fitting, contact region with the second housing part 12' can be provided in the region of the recess 19 of the first housing part 12, as a result of which the movement of the drive 16 or of the transmission on the actuating body 11 or the rack 13 can be made possible.

Furthermore, an electronic controller 18 can be provided, which is arranged in one of the housing parts and is designed to control the drive 16 on the basis of an input signal and either to start it (and to maintain the operation for the desired duration) and / or to stop it. The opener 10 can be connected to any sensor or touch device that can trigger a movement of the drive 16. Preferably, a signal transmitter, for example in the form of a pin 20, is arranged in a front region of the actuating body 11, the relative movement of which relative to the housing 12, 12 'and / or relative to the electronic control 18 can activate the drive 16. This can be, for example, a pressure device that is spring-loaded with respect to the housing, which enables the actuating body 11, which is otherwise guided on the drive side, to be moved relative to the housing or the electrical control 18, and thus a signal for actuating the drive to provide.

This signal can be provided, for example, by the electronic control 18 by actuating a switch or other movable element which is attached to the electronic control and which can interact with the signal transmitter 20. poses. By actuating the switch on the electronic control 18, for example by contacting it with the pin 20, the control 18 receives a signal and can control the drive 16 so that it starts operating. In principle, both the drive 16 and the electronic control 18 can be designed to stop operating independently after a predefined time or distance of the actuating body 11 relative to the housing 12, that is to say when the actuating body 11 has reached the working position of the actuating body. This can prevent excessive loading of the drive 16 or the other components of the opener according to the invention.

In addition or as an alternative to this, the actuating body 11 can also be designed with a mechanical limitation relative to the housing 12, as a result of which the actuating body 11 can be prevented from moving beyond a maximum desired position. Both the electronic / electrical limitation of the distance of the actuating body between the rest position and the working position and the mechanical limitation can be provided in an adjustable manner. The mechanical limitation can be, in particular, a pin or a projection on the housing 12 of the actuating body, on the actuating body itself or on the rack 13, which is connected to the one corresponding part (housing 12 of the actuating body, actuating body itself or on the rack 13 or on the housing12) interacts to limit movement.

The connection between the electronic control 18 and the drive 16 is shown in FIG. 1 as a dashed line within the housing 12 'and can be provided as desired, for example as a wire connection. Basically, in addition to or as an alternative to the signal transmitter 20, an actuating element 21 can be provided between the actuating body 11 and the toothed rack 13 on the front side of the actuating body 11, which is in operative connection with the electronic control 18 and / or the drive 16 and, when actuated, has a connection Activation of the drive 16 causes whereby the actuating body 1 1 is movable between the rest position and the working position.

The recess 19 already discussed can also extend over part of the housing 12, as a result of which a particularly positive connection is provided between the individual housing parts. Thus, on the one hand, the housing 12 can have a recess for at least a second housing part 12 'and, on the other hand / or a guide in the housing 12 for the actuating body 11 or for the rack 13 can have an area in which an interaction between - The drive 16 or gear 14, 15 and the toothing, in particular the rack 13 or a toothing of the actuating body 11 is made possible.

The actuating body 1 1 can also be referred to as an ejection punch and the first housing part 12 as a guide sleeve. Together, these two parts can form a so-called ejection unit, which can be inserted at the end in a corresponding bore in a body or frame. In contrast, further parts of the opener 10 according to the invention can be provided at least in a second housing part, which is also referred to as a built-in housing, the built-in housing and ejection unit being at least partially positively connectable to one another. The transmission of the rotary movement of the drive to a flush movement of the ejection punch can be carried out via a gear in the contact area between the ejection unit and the installation housing.

In the front area of the ejection ram 12, a damper can be used, in addition or in addition to an actuating element 21, which controls the mechanics of the opener 10 according to the invention in the event of thoughtless additions or in the case of a strongly spring-loaded door, which can close independently, by absorbing the force acting on the door or of the opening lock, can protect.

Actuating element 21 and signal transmitter 20 can also form a unit and jointly provide a signal to the electronic control 18 around the drive 16 to control. According to the present invention, the elements 20 and 21 can also be provided as an alternative.

FIG. 2 shows in an exploded view an arrangement of a preferred embodiment of the opener 10 according to the invention, in which the ejection unit, that is to say the actuating body 11 in the housing 12, can be provided via an opening 23 for the first housing part, for example an end face bore, and the second Housing part 12 'can be provided in a lateral recess, for example a drilled blind hole 24.
