Description

  The present invention is a retracting device, in particular for a slide element, a drawer or a sliding door, provided with a housing, the housing containing a buffer element, the buffer element comprising a piston rod, The rod accommodates a piston which is guided so as to be displaceable in the buffer cylinder, the housing accommodates a connecting element, and the connecting element is located between the retracted position and the retracted position in the slide guide of the housing. A tension spring is connected to the connecting element, and the tension spring relates to the connecting element preloading the connecting element in the retracted position toward the retracted position.

  A retractor is known from EP 1 658 785 A1. Here, a shock-absorbing element is mounted in the housing, which comprises a shock-absorbing cylinder, in which the piston can be displaced with respect to the shock-absorbing fluid. A piston rod is connected to the piston.

  The piston rod is attached to the guide carriage at the free end. The guide carriage is linearly displaceable within the slide guide of the housing. The guide carriage includes a bearing overhanging portion, and the bearing overhanging portion engages with the bearing housing portion of the connecting member, and a swivel bearing is formed between the two portions. As a result, the connecting member can be turned to the lower turning position with respect to the guide carriage in the pulled-out position.

  The object of the present invention is to provide a device which improves the retracting device mentioned at the beginning and guarantees a high functional certainty with little effort on parts and mounting. This problem is solved by the fact that the piston rod is directly connected to the coupling element by means of a slewing bearing. Based on the direct attachment of the connecting element to the connecting rod, the guide carriage can be omitted. This greatly reduces the labor involved with the parts and mounting. Furthermore, the force application points of the connecting elements are placed relatively densely on the piston rod, so that a stable structure with a relatively high functional certainty is obtained.

  According to an advantageous embodiment of the invention, the swivel axis of the swivel bearing extends in the region of the slide guide. In this way, the bending forces which act on the piston rod and can occur during the downward pivoting of the connecting element are completely eliminated or at least very slightly maintained.

  Particularly in the space-saving structure, with respect to the retracting device, the connecting element is guided by the bearing pin so as to be displaceable in the slide guide, and the bearing pin is linearly moved in the linear guide section of the slide guide from the retracted position of the connecting element. And is realized by the piston rod being aligned with the linear guide section.

  In this way, the housing is realized in the form of a vertically long structure having a relatively small structural height or structural width. The vertically long structure type can be easily assembled, particularly in a narrow space situation in the drawer guide.

  If the connecting element is guided by the bearing pin so as to be displaceable in the slide guide, and the pivot axis of the connecting element extends through the bearing pin, the guide of the connecting element in the slide guide is simple and space-saving. Can be realized.

  In this case, if the bearing pin couples the connecting element with the bearing overhang of the piston rod, a further reduction in the partial costs can be realized. The bearing pins can be molded as individual components or directly on the connecting element or the piston rod.

  According to another aspect of the invention, the coupling element comprises a spring holder, to which the tension spring is spaced from the pivot axis of the slewing bearing and is directly connected in a knitted manner. Has been. A tilting moment can be formed by assigning the point of action of the spring to the connecting element. Assured by the tilting moment, the connecting element is reliably pulled to a position that is pivoted downwards in the extended position.

  The slide guide is provided with two guide slits, the guide slits are cut out from the two housing walls of the housing parallel to each other, and the connecting elements are respectively connected by bearing pins between the housing walls. By being guided in the guide slit, a reliable guide which is stable against tilting of the connecting element is achieved with little effort.

  According to one aspect of the present invention, the connecting element includes at least one guide element, the guide element is guided in the slide guide, and is placed in the receiving portion of the slide guide at the pulled-out position. It turns and enters.

  The connecting element includes first and second stoppers, the first and second stoppers are arranged with a mutual interval, and the second stopper is supported by the spring element; If the spring element is displaceable in a displacement direction extending generally in the swiveling direction of the connecting element, the retracting device can be used selectively on both sides of the slide element to be guided. The spring element always escapes towards the housing interior.

  A further reduction in labor associated with the parts is realized when the spring element is integrally joined with the connecting element.

  Furthermore, the invention is a retracting device, in particular for a slide element, a drawer or a sliding door, provided with a housing, the housing containing a buffer element, the buffer element comprising a piston rod, The piston rod accommodates a piston that is guided so as to be displaceable in the buffer cylinder, the housing accommodates a connecting element, and the connecting element is located between a retracted position and a retracted position within the slide guide of the housing. A tension spring is connected to the coupling element, the tension spring being related to preloading the coupling element in the retracted position towards the retracted position.

  The object of the present invention is to improve the above-mentioned retracting device, and the two retracting devices are arranged in space-saving on the opposite sides of the entrainment bodies such as furniture, doors, door frames, etc., and can be operated by the entrainment bodies at the same time. It is to provide something like that.

  This problem is solved by the fact that the stopper is arranged between the central cross section and one of the fixed planes, and the stopper does not protrude beyond the central plane.

  Here, the retracting device can be positioned on both sides of the entrainment body, in which case the stoppers of the connecting elements overlap. In this way, in particular the same two retracting devices can be used, which provides a clear handling advantage.

  In particular, according to one aspect of the present invention, the connecting element includes two stoppers, the stoppers are arranged one after the other in the displacement direction of the connecting element, and both stoppers are arranged on one side of the central plane. Or each stopper is arranged on one side of the central plane, and both stoppers do not protrude beyond the central plane.

  Next, the present invention will be described in detail based on the illustrated embodiment.

It is a side view which shows a drawing-in apparatus in the state with a connection element in a drawing-out position. It is a side view which shows a drawing-in apparatus in the state which has a connection element in the drawing-in position corresponding to FIG. It is a fragmentary perspective view of the drawing-in shock absorber shown in FIG. It is a perspective view which shows the connection element to which the buffer element and the tension spring were connected. FIG. 5 is a perspective view showing the connecting element at a changed functional position corresponding to FIG. 4. It is a horizontal fragmentary sectional view which shows a drawing-in apparatus along the VI-VI line of FIG. It is a perspective view which shows two drawing-in apparatuses which form a row | line | column mutually. It is a figure which shows two drawing-in apparatuses arrange | positioned relatively.

  1 and 2 show a retracting device 10 including a housing 12, and the housing 12 includes a fixed overhanging portion 11 at an end portion on the longitudinal direction side. The fixed overhanging portion 11 includes a screw accommodating portion. As can be clearly seen from FIG. 3, the housing 12 comprises two housing walls 12.3 that are parallel to each other, the housing wall 12.4 extending between the fixed overhangs 11. ing. A slide guide 12.2 formed as a guide slit is cut out from the fixed wall 12.4. Both slide guides 12.2 are overlapped. The slide guide 12.2 is provided with a linear guide section, and the linear guide section moves to the wide accommodating portion 12.3. A connecting element 20 is attached to the housing 12 so as to be displaceable. The structure of the connecting element 20 formed as an injection-molded part can be seen in detail from FIGS. As shown in FIGS. 4 and 5, the connecting element 20 includes a base portion 21.1, and a holder 21 as an extension arm is integrally formed with the base portion 21.1.

  The holder 21 includes a spring element 23 formed in a plate shape. The spring element 23 is provided with a second stopper 24 having a stopper surface 24.1 at the free end. The second stopper 24 ends at a locking overhang 24.2 directed to the holder 21. As can be clearly seen from FIG. 6, the second stopper 24 contacts the retracted guide surface 26 of the holder 21. At the same time, the second stopper 24 and the holder 21 are provided with an undercut surface, and the undercut surfaces contact each other to form a guide 24.3. The guide 24.3 prevents escape of the second stopper 24 perpendicular to the guide surface. In FIG. 4, the spring element 23 is shown displaced inward, and in FIG. 5, it is shown displaced outward.

  In the displaced state, the locking overhang 24.2 restricts the complete expansion. When the locking overhang 24.2 is disengaged from the holder 21, the spring element 23 is fully expanded, so that the locking overhang 24.2 is released and exceeds the holder 21. Occupy an extended posture. The extended position is the starting position from which the connecting element is removed from the injection mold and can therefore be produced without undercutting.

  The base portion 21.1 further includes a first stopper 25, and the first stopper 25 projects in the same direction as the second stopper 24. As shown in FIG. 5, since both the stoppers 24 and 25 have a mutual space | interval, the stoppers 24 and 25 define the accommodation space between them.

  The buffer element is connected to the connecting element 20 so as to be directly pivotable. The buffer element comprises a buffer cylinder 30 in which the piston can slide with respect to the pressure of the buffer fluid (gaseous or liquid). The piston includes a piston rod 32, and the piston rod 32 is guided outward from the buffer cylinder 30.

  The piston rod 32 includes a bearing overhang portion 33 at the free end. The bearing overhang portion 33 is rotatably held in the bearing housing portion 28 of the connecting element 20. FIG. 6 illustrates the coupling between the piston rod 32 and the connecting element 20. Accordingly, the bearing overhang portion 33 and the bearing housing portion 28 are provided with holes that are aligned with each other, and the bearing pin 29 that is formed as a separate component part and that is formed as a separate component is guided through the hole. ing. The bearing pin 29 is held on the bearing overhang portion 33 or the bearing housing portion 28 by frictional coupling (kraftschluessig). Accordingly, a slewing bearing is formed, and the slewing axis of the slewing bearing extends through the central axis of the bearing pin 29. In another form, not shown, according to the present invention, the piston rod 32 and the connecting element 20 comprise a molded component that engages and interleaves to form a swivel bearing.

  For example, the bearing pin 29 can be integrally formed with the connecting element 20 (or piston rod 32), and the piston rod 32 (or connecting element 20) can be fitted over the bearing pin 29 with a hole. Therefore, the bearing pin 29 as an individual member can be omitted.

  As can further be seen from FIG. 6, the bearing pin 29 protrudes from the connecting element 20 on both sides, in which case the protruding section engages the slide guide 12.2. The connecting element 20 is thus stably guided between the two housing walls 12.4 and in the slide guide 12.2.

  Furthermore, as can be seen from FIG. 5, a spring holder 27 is arranged below the swivel bearing. The spring holder 27 fixes the end of the tension spring 35, and the tension spring 35 is fixed to the housing 12 at another end. A rotational moment acting in the clockwise direction (FIG. 5) about the pivot axis of the slewing bearing can be formed by the arrangement structure in which the connection points of the tension springs 35 are spaced apart.

  As shown in FIGS. 1 to 3, the arrangement structure shown in FIGS. 4 and 5 is attached to the housing 12.

  In this case, the buffer cylinder 30 is inserted into the groove-shaped accommodation portion of the housing 12. In the axial direction, the buffer cylinder 30 is attached by an overhang portion 12.5 protruding from the housing wall 12.5, and the overhang portion 12.5 engages a circumferential groove 31 attached to the buffer cylinder 30.

  A through hole 12.1 is formed in the housing wall 12.4, and the through hole 12.1 ensures that the buffer cylinder 30 is not detached.

  In FIG. 1, the connecting element 20 is shown in the starting position. Here, the connecting element 20 is swiveled downward with respect to the piston rod 32 in a swivel bearing, and on both sides, guide elements 22 integrally formed on the side of the holder 21 of the connecting element 20 are slide guides 12.2. Are held in both housing parts 12.3. In this position, the tension spring 35 is in a tensioned position and exerts a preload on the connecting element 20, which is held in a position pivoted downward. As shown in FIG. 1, the connecting element 20 can already engage the entrainment body 40 in the position shown. In this case, the entrainment body 40 is stationary and can be attached to, for example, a furniture body (sliding door-door frame), and the retracting device can be attached to a slide portion (drawer, sliding door, etc.) to be moved (or its). Vice versa).

  When the entrainment body 40 abuts on the first stopper 25 in the movement direction of the slide portion to the closed position (see F in FIG. 1), the guide element 22 moves out of the housing portion 12.3. In this case, the connecting element 20 turns around the turning axis of the turning bearing. The entrainment body 40 is entrained by the second stopper 24.

  The collision of the entrainment body 40 with the first stopper 25 is buffered by the buffer element (buffer cylinder 30). Therefore, the slide portion is pulled to the closed position by the force of the tension spring 35. Upon opening of the closing part, the connecting element 20 is pulled by the entrainment body 25 in contact with the second stopper 24 and brought into the position shown in FIG. In this case, the tension spring 35 is tensioned again and the connecting rod 32 is pulled out. The slide part is thus disengaged from the retracting device and can continue to move to the open position. Therefore, for example, due to a functional error, the connecting element 20 exists at the position shown in FIG. 2, but the entrainment body 40 is outside the region formed between the stoppers 24 and 25, and the second stopper It is possible to exist in front of 24.

  When the entrainment body 40 moves toward the second stopper 24, the entrainment body 40 rides on the spring element 23 placed obliquely in the movement direction. The entrainment 40 displaces the spring element 23 into the housing 12 perpendicular to the direction of movement F. When the entraining body 40 passes through the second stopper 24, the spring element 23 pivots upward again, and the entraining body 40 is positioned between the stoppers 24 and 25 accurately (see FIG. 2).

  FIG. 7 shows an arrangement used for a relatively heavy slide portion (for example, a relatively large sliding door). In this case, the two retracting devices shown in FIGS. 1 to 6 are placed side by side. Accordingly, the retracting device brakes the entraining body 40 that is arranged in parallel and simultaneously contacts both the connecting elements 20 with the buffer element.

  Another arrangement structure arranged in parallel is shown in FIG. As shown in FIG. 8, the retracting devices are arranged to face each other, and in this case, the housing walls 12.4 are located on one plane in pairs.

  Here, the stoppers 24 and 25 overlap. As shown in FIG. 6, the retracting device has two fixing planes E that are parallel to each other. At the fixing plane E, the retracting device can contact the fixing surface and be attached to the fixing surface. A central cross section M of the retracting device is located in the center of the fixed plane E and parallel to the fixed plane E. As can be seen from FIG. 6, the stoppers 24 and 25 do not protrude from the central cross section M, so that the overlapping positions of the stoppers 24 and 25 shown in FIG. 8 are obtained.
