Description

  The present invention relates to a retraction device, in particular a retraction device for drawers, sliding doors or hinged doors or swivel doors or hinged windows or swivel windows, etc., wherein the spring force is applied by a spring. The connecting piece is of a type that is movable between a retracted position and a delivery position. The invention further relates to a method for operating a drawer or the like or a sliding door or a hinged door or a swivel door or a hinged window or a swivel window.

  A retraction device for withdrawal is known from German Offenlegungsschrift 10 2007008688 A1. The known retracting device has a tilting member as a connector or a connecting piece, and the tilting member (swivel member) is moved from the retracted position to the running position against the spring stress when the drawer is opened. It has become. In this case, the tilting member is moved by the accompanying body. When the tilting member reaches the running position, the tilting member disengages from the entrainment body, and the drawer is continuously pulled out by inertia. If the drawer is closed again, the drawer is moved until the entrainment body is caught by the tilting member. Subsequently, a pre-tensioned spring pulls the drawer to the closed position. In this case, in order to prevent a strong collision of the drawer, the pull-in movement is braked using a damper.

  There is a tendency for drawers without handles for aesthetic reasons. However, known drawers with a retracting device hold the drawer in a closed position under the action of a spring, so that it can still not be pulled out without a handle or grip, i.e. it cannot be opened. is there.

  An object of the present invention is to improve the drawer operability by improving the drawer apparatus of the type described at the beginning.

In order to solve the above-described problem, according to the configuration of the present invention, the extrusion device is connected to the connection piece indirectly or directly, and the slide piece of the extrusion device is activated when the extrusion device is operated. It has come to be. The extrusion apparatus, the drawer from a closed position, is caused to travel to the partially extruded parts partial open- position, that is adapted to be moved. In this case, the slide piece becomes effective and the drawer is moved. As a result, the partially opened drawer is, for example, grasped by its front plate and further pulled out to the opened open position.

  In the retracting device according to the present invention, the damper is configured to attenuate or brake the moving motion of the connecting piece from the delivery position to the retracted position, so that a controlled closing motion is obtained. .

  According to an advantageous embodiment of the invention, the connecting piece is actuated or operated (eg a slit-like guide or guide, guide (guide) when the slide piece is in its delivery position, ie when the slide piece is in its delivery position. ), A notch or guide extension extending substantially perpendicularly to the guide, and an entrained body guided in the guide). In this case, the slide piece is It is movable relative to the connecting piece held at the mooring position.

  According to the embodiment of the present invention, the slide piece of the extrusion device is movable between the pushing position (running position) and the pushing position (running position) in order to obtain a prescribed movement process of the pushing device. It has become.

  According to the embodiment of the present invention, in order to form the pull-in device with a simple and inexpensive structure, the push-out device has a spring element, and the spring element (for example, a coil spring) is inserted into the slide piece in its push-in position. A load (spring force, for example, pressing force) is applied. The spring element is adapted to apply the spring energy of the spring element to the slide piece in the closed position of the drawer during operation of the push-out device. Thereby, the drawer is moved to a partially opened position.

  According to a particularly advantageous form of the invention, the extrusion device has an overstroke mechanism for eliminating or releasing the push-in position, i.e. an over-stroke for allowing the slide piece to move beyond its defined push-in position. It has a mechanism. This makes the retraction device particularly easy to operate. In order to start (start) the operation of the push-out device, the overstroke mechanism is operated by simply pressing the front face of the drawer, for example, corresponding to the configuration of the drawer.

  According to an advantageous embodiment of the present invention, the push-out device has a support and is provided with a latch supported by the support, and the latch is effective in moving the slide piece from the push-out position to the push-in position. That is, the locking portion provided on the rail made of two wall elements, i.e., angle members, is arranged, for example, at an angle with respect to the predetermined distance of the slide piece or the pushing stroke of the push rod of the pushing device. The latch allows the relative movement of the slide piece relative to the support, so that the actuated (released) extrusion device is again charged (charged). It has become so.

  In order to prevent the unintentional start of operation of the push-out device, the slide piece is locked (secured or fixed in position) using a lock piece in the push-in position of the slide piece, according to an advantageous embodiment of the invention. ing.

In a method for operating a drawer (or sliding door or hinged door or swivel door or hinged window or swivel window, etc.), in order to solve the problems of the present invention, according to the structure of the present invention, the closed position of the drawer in the extrusion apparatus is started (operation starting) from the drawer by the extrusion device its closed position, is moved to the section partial open- position partially opened, then, when the drawer of subsequent transfer from part partial open- position, the spring Generates a stress or a tensile force.

In a method for operations such as drawers, the extrusion device is used for easy opening from the closed position of the drawer. If the further drawing out from a drawer a part partial open- position, the drawer movement is used for the generation of stress or tension force of the spring (energy storage), springs, later, the stress upon retraction of the drawer into the closed position It releases, that is, it consumes energy.

To particularly easily implement the above operation process, according to an advantageous embodiment of the present invention, during the opening of the drawer from Part partial open- position, connecting pieces, transferred from the retracted position to the extended position, the drawer position In achieving this, the connecting piece is moved to the parking position (spring mooring position), and the connection between the push-out device and the connecting piece is released.

  For the start-up of the push-out device (release or trigger) from the closed position of the drawer or the push-in position of the push-out device, the overstroke mechanism is operated, in particular a simple operation of pull-out without a handle is achieved.

  When the drawer is moved in the direction from the open position or open position of the drawer or partially opened position or partial open position to the closed position, the push-out device is moved from the push-out position (running position) to the push-in position (running-in). The position of the push-out device is moved to the push-in position as the drawer is closed, that is, the return movement of the push-out device to the push-in position is incorporated into the natural movement process of the drawer. Therefore, it is extremely simple, that is, easy to operate without requiring a troublesome additional operation.

  According to an advantageous embodiment of the invention, the extrusion device is pulled using a spring to the closed position of the drawer and at the same time using a damper in order to loosen the return movement stroke of the extrusion device or the closing process of the drawer. Damped or damped.

  FIG. 1 shows a retracting device, which is used for, for example, a drawer. In other possible embodiments, the retraction device according to the invention is also used for movable building components, such as doors, flaps, hinged doors or revolving doors or revolving windows. The retracting device includes a coupler 29, which may be formed in a plate shape, for example, attached to a drawer (not shown).

  The retracting device further includes a casing 10, which has a screw receiving portion 11.1, which enables the retracting device to be fixed to the outer frame side of furniture or the like. Yes. The casing 10 has two side walls 11 that are spaced apart from each other in parallel, and a guide 11.2 is formed on the side walls. The guide 11.2 has a slit-shaped through portion, and the through portion communicates with a notch portion 11.21 having an increased width. The guides 11.2 on both side walls 11 coincide with each other, i.e. align relative to each other, i.e. they are formed mirror-symmetric with respect to each other. The casing 10 is integrally provided with a rail 40, which includes two wall elements 41, 43 positioned at an angle to each other. The wall elements 41 and 43 are used for supporting the outer frame surface. The wall 41 has a locking portion, which is formed by a row of locking elements 42. The locking elements 42 are preferably arranged spaced apart at the same pitch. The locking element 42 has a locking release inclined surface 42.2 that is inclined in the pull-out direction of the drawer, and the locking release inclined surface has shifted to a steep locking surface 42.1. .

  In FIG. 2, the right-hand part of the retracting device is shown enlarged in cross-section for easy understanding of its function. A damper 12 is accommodated in the casing 10. The damper 12 is formed as a fluid attenuator or a fluid damper, preferably as an air damper. As an advantage of using the air damper, there is no occurrence of liquid leakage at the time of breakage, and therefore there is no possibility of soiling the contents in the drawer. The damper 12 has a cylinder 12.6 and a piston 12.2 received in the cylinder, and the piston 12.2 is located in the pushing position (running-in) shown in FIG. From the position), it is moved in the running direction, that is, pulled out. During the return movement (running movement) of the piston 12.2, the piston 12.2 works against the air cushion, and in this case, the air pressure is continuously released. For this purpose, the insert 12.3 is provided with a small opening that allows the compressed air to escape and be controlled. The piston rod 12.1 has a head portion 12.4 at the end of the piston rod opposite to the insert 12.3, the head portion forming a pivot support 12.5. ing. In the swivel support portion 12.5, a connecting piece 13 formed as a swiveling element or a tilting element is rotatably held. In this case, the turning motion is performed around a turning axis perpendicular to the drawing plane of FIG. A spring holder 13.1 is arranged on the connecting piece 13, and the spring holder holds one end of the spring 14. The other end of the spring 14 is hung on the casing side.

  The connecting piece 13 has a trigger 13.2 arranged at a distance from the pivot axis. Further, the connecting piece 13 is provided with an entraining body 13.4, which may be integrally formed with the arm 13.3 of the connecting piece 13, for example. The coupling portion 30 of the extrusion device 20 is detachably coupled to the entrainment body 13.4.

  Next, the configuration of the extrusion device 20 will be described in detail with reference to FIG. The extrusion device 20 includes a coupling portion 30 as described above, which has a support 31 and an end piece 35 for releasable coupling with the coupling piece 13. It is used for.

  The coupling portion 30 has a receiving portion 36, and the entrainment body 13.4 enters the receiving portion. The receiving portion 36 is provided on the end piece 35 of the coupling portion 30. The end piece 35 is integrally formed with a protrusion-like additional portion as an unlocking portion 37. The end piece 35 is held by the support 31. The support 31 has a lock receiving portion 32. Furthermore, a latch 33 is supported on the coupling part or push-out device 20 so as to be pivotable about a pivot axis 33.4 extending perpendicular to the plane of the drawing. The latch 33 consists of a locking section 33.1, a locking release section 33.2 and a stopper 33.3.

  In the coupling portion 30, the push rod 24 is held at an end portion 38 on the side opposite to the end piece 35 via a screw coupling portion. For this purpose, the push rod 24 is screwed into the female screw 38.1 of the coupling part 30 with the male screw 24.1. The push rod 24 supports a locking ring 24.2, and the locking ring is held in the bearing receiving portion of the push rod 24 so as to be rotatable in the circumferential direction. The locking ring 24.2 has a locking element, which is guided in the control cam 23 of the slide piece 21 formed in the shape of a hollow cylinder. The control cam 23 is formed by a groove formed on the inner wall of the slide piece 21. The control cam 23 and the locking ring 24.2 of the push rod 24 form an overtravel mechanism. The function of the overstroke mechanism corresponds to the function of the knock mechanism of the knock type ballpoint pen. In this case, the push rod 24 corresponds to the knock head of the knock mechanism of the knock type ballpoint pen (also called a ratchet mechanism). To do. A spring element 22 formed by a coil spring is accommodated in the slide piece 21 and guided by the wall of the slide piece 21 so as not to buckle.

  As can be seen from FIG. 3, a lock piece 28 is pivotally attached to the holder 26 of the slide piece 21 via a support portion 27. The lock piece 28 has an unlocking piece 28.1 and an arm 28.2. Arm 28.2 supports locking element 28.3.

  As can be seen from FIG. 1, the coupler or coupling device 29 is integrally connected to the slide piece 21, and the number of parts is reduced by such a configuration.

  Next, based on FIGS. 4-14, the function of the drawing-in apparatus of this invention is demonstrated in detail.

  FIG. 4 shows the starting position of the retracting device, in which the drawer is in the closed position. The closed position of the drawer or the starting position of the retracting device is a position where the connecting piece 13 is in the retracted position. The overstroke mechanism is in the locking position (lock position), that is, the locking ring 24.2 is locked to the locking addition portion of the control cam 23. The latch 33 is held in the unlocking position that is pivoted upward by the unlocking portion 25 of the slide piece 21. For the operation of the overstroke mechanism, an overstroke Ue is introduced in the direction of the original drawer movement, for example via the drawer front. The excess stroke Ue is transmitted to the slide piece 21 through the coupler 29. Thereby, the slide piece 21 is moved over a slight distance relative to the push rod 24 against the stress or compressive force of the spring element 22 in the direction of the over travel Ue. As a result, the locking position (locking position or fixing position) of the locking ring 24.2 in the control cam 23 is canceled or released, that is, the locking ring 24.2 is lifted from the locking position in the control cam 23. That is, it is moved beyond the locking position and rotated in the circumferential direction to reach the straight section of the control cam 23. FIG. 5 shows the position of the slide piece 21 that is moved and occupied by the excess stroke Ue. As shown in FIG. 5, the latch 33 also has its unlocking section 33.2 lightly lifted by the unlocking part 25, ie displaced upwards.

  Now, when the pushed drawer is released from the pushing force, the slide piece 21 is moved to the lock piece 24.2 and the slide piece 21 based on the release of the lock coupling portion between the control cam 23 of the slide piece 21. It is moved from the pushing position (FIG. 4) to the pushing position (running position), that is, moved (transition from FIG. 5 to FIG. 6). This movement is effected by a spring element 22 that is under stress in the indented position, that is, compressed in the illustrated embodiment and pressing the slide piece 21.

  FIG. 6 shows the pushing position. The movement (movement) of the slide piece 21 is transmitted to the drawer via the coupling device 29, and as a result, the drawer is moved to the first partial opening position.

When the slide piece 21 is moved, the latch 33 is released from the slide piece 21 and is turned downward to the position shown in FIG. 6 based on gravity. The movement (downward turning movement) of the latch 33 to the position shown in FIG. 6 may be supported by a spring as necessary. As shown in FIGS. 4 and 5, the lock piece 28 is engaged with the wall element 11.3 of the casing 10 as shown in FIGS. In other words, the unlocking piece 28.1 prevents the locking element 28.3 from engaging in the lock receiving part 32. When the slide piece 21 is moved, the lock piece 28 is disengaged from the wall element 11.3, that is, disengaged from the wall element 11.3, and is held in the position shown in FIG. 6 by a spring (not shown). Be drunk. In this case, the locking element 28.3 is adapted to slide along the surface of the support 31. When the position shown in FIG. 6 is achieved, the drawer is grasped to facilitate manually, partially drawn to another part partial open- position, or becomes to be fully extended to fully open the open position. In this case, the pushing device 20 connected to the drawer is also moved in the opening direction Oe. Since the connecting piece 13 is connected to the connecting portion 30 and thus connected to the extrusion device 20, the connecting piece 13 is moved in the opening direction Oe. In this case, the connecting piece 13 is guided by the guide 11.2. The connecting piece 13 entrains the piston rod 12.1 of the damper 12 and consequently moves the piston 12.2. Along with this, a stress is created in the spring 14, i.e., the spring 14 is pulled or stretched in the illustrated embodiment. In this case, the connecting piece 13 is pulled by the pushing device 20 until the entrainment body 13.4 guided in the guide 11.2 reaches the region of the notch 11.21. The connecting piece 13 is tilted (turned) about the turning shaft 12.5 by the spring 14 acting eccentrically with respect to the turning shaft 12.5, and the entrained body 13.4 is moved into the notch 11.21. Will get into. As a result, the entrainment body 13.4 is disengaged from the receiving portion 36 of the coupling portion 30. That is, since the coupling between the push-out device 20 and the connecting piece 13 is released, the drawer is continuously pulled out, that is, starts running due to inertia. The connecting piece 13 is moved to the starting position shown in FIG. In the transition of the extrusion device from the position of FIG. 6 to the position of FIG. 7, the latch 33 abuts against the edge 15 of the casing 10 at its unlocking section 33.2 and is lifted by this edge. In other words, it is swung upward and enters the region of the rail 40 (see FIG. 7). When traveling in the region of the rail 40, the latch 33 moves beyond each locking element 42, i.e. lifted along each locking release inclined surface (riding surface or displacement surface) 42.2, i.e. It is pivoted upwards so that after each locking element 42 it enters after each locking surface 42.1 with a locking section 33.1 of the latch 33. In this way, the drawer is moved to a desired respective portions partial open- position, or fully extended, where the latch 3, the rail 40 and engaged with will be locked.

Figure 8 shows one part partial open- position. It will now be described closing of the drawer from the partial open- position (pushing). Closing process shown in FIG. 8 (pushing process) also applies to the closure of the release other parts partial open position or fully open position (fully open position).

  The drawer is now pushed in the closing direction S. In this case, the pushing device 20 which is connected to the drawer via the coupling device 29 is also moved in the closing direction, which also means that the latch 33 of the first locking element 42 in front of the latch in the closing direction. It is moved until it hits the locking surface 42.1. The latch 33 is adapted to prevent (lock) movement of the coupling part 30 by striking against the locking surface 42.1 of the locking element 42 (see FIG. 9). However, since the slide piece 21 is moved towards the coupling part 30, the push rod 24 is pushed into the slide piece 21 and the spring element 22 is compressed, so that the pushing device is re-loaded, in other words. If energy is stored, that is, it will be charged. When the slide piece 21 reaches the push-in position shown in FIG. 10, the locking ring 24.2 is locked in the control cam 23, so that the slide piece 21 is secured in the push-in position on the coupling part 30. In other words, it will be stopped. At the same time, the locking element 28.3 of the locking piece 28 enters the lock receiving part 32. Thereby, reliable locking is achieved. Such a lock prevents the coupling between the slide piece 21 and the coupling portion 30 from being released due to, for example, shocking motion or vibration. The moved slide piece 21 also releases the locking connection formed by the latch 33 at the end of the moving stroke. For this reason, the unlocking portion 25 of the slide piece 21 pushes the latch 33 away from the locking surface 42.1 with the unlocking inclined surface (see FIG. 10).

  The drawer is moved by inertia until the drawer specifically reaches the position shown in FIG. Subsequently, the unlocking portion 37 of the push-out device 20 hits the trigger 13.2 and actuates the trigger, and as a result, the connecting piece 13 is actuated around the pivot axis 12.5. Thus, the entrainment body 13.4 is pushed out from the notch 11.21 until it reaches the area of the guide 11.2.

  The entrainment body 13.4 engages in the receiving portion 36 of the coupling portion 30 when being pushed out (running out) from the notch portion 11.21, whereby the coupling portion between the coupling piece 13 and the extrusion device 20 is engaged. (See FIG. 12). As a result, the parking position (spring mooring position) is canceled, and the spring 14 is relaxed, that is, contracts. The pushing device 20 is also pulled in the closing direction S by the spring force released while shrinking, and the drawer is pulled in the closing direction S via the pushing device. In this case, the damper 12 is also activated to brake the closing movement generated by the spring 14.

  As shown in FIG. 13, the locking piece 28 comes into contact with the wall element 11.3 during the aforementioned retraction movement with the unlocking piece 28.1 of the locking piece. As a result, the locking element 28.3 is removed from the lock receiving part 32, i.e. pulled out, i.e. unlocked, and the pushing device 20 is moved to a state for the next opening of the drawer.

  FIG. 14 shows the fully retracted position of the retracting device, with the connecting piece 13 in the retracted position and the slide piece 21 in the pushed in position. The drawer is also completely closed.
