Description

The present invention relates to a fitting system for guiding a closure flap of a piece of furniture according to the preamble of claim 1.

Corresponding fitting systems are well known and are usually arranged or fastened on inner sides of the piece of furniture. Usually, the known fitting systems comprise a linkage construction, by means of which the closure flap is coupled to the piece of furniture.

The piece of furniture is usually a cabinet or a cabinet unit, such as a wall cabinet. However, the cabinet may also be a part of a cabinet system with a plurality of cabinet modules having a plurality of openings, each of which is closable by means of corresponding flaps. The piece of furniture may also be, for example, a wall unit of a desk below a desk top or a container.

In the known from the prior art fitting systems, a damping device may be provided by means of the end phase of the movement of the shutter is damped. By a corresponding damping of the movement of the closure flap, the closure flap is gently brought to its end position, whereby the impact speed of the closure flap is reduced to the rest of the body of the piece of furniture, so that the noise and the burden for both the piece of furniture and for the flap are reduced ,

Since the known fitting systems are placed on the inner surfaces of side walls of furniture, this leads to a loss of storage space within the furniture or within the cabinet. Also, due to the complicated linkage designs, the production of the fitting systems is complicated and costly.

The DE 203 07 207 U1 discloses a hinged-sliding door fitting for flaps or doors of a cabinet cabinet. In the respective two side walls of the cabinet furniture grooves are provided, in each of which an L-shaped guide rail is arranged. The guide rail comprises a first guide groove and a second guide groove, wherein the guide groove is vertical and the guide groove are aligned horizontally. In the guide grooves and each guide pins of the flap are receivable and feasible. In the first guide groove damping means are arranged in the form of damping and / or braking cam. The damping cams cause a damping of the movement sequence when turning a flap in the closed position. The lower of the two guide pins of the flap can be brought into contact with the damping cams. The damping cams thereby exert on the guide pin one of the weight of the flap counteracting braking force, the smaller as the weight force exerted by the guide pins on the damping means.

The US 2004/0174101 A1 discloses a striker comprising a cylinder, a piston rod engageable in and out of the cylinder, and a piston. The buffer mechanism is attached to a telescopic rail for a drawer, so that when closing the drawer, a stop of the telescopic rail with the piston of the locking mechanism is brought into contact, so that a closing movement of the drawer is damped by the buffer mechanism.

From the US 2,189,233 A. a fitting system according to the preamble of claim 1 is known. The damping device comprises a helical spring there, which can be compressed by the force of gravity when the closure flap is closed. The coil spring is supported at its lower end on a fixed base.

Furthermore, from the EP 2 088 270 A1 a clip system with which a piston-like damper can be attached to a slider.

The object of the present invention is therefore to provide an improved, but simple fitting system, which leads to little or no loss of storage space within the piece of furniture or cabinet, is inexpensive to manufacture, requires only a low installation effort and easy to different flap geometries and flap weights is customizable.

This object is achieved with the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

In the fitting system according to the invention, a damping device is embedded in the fitting body in an end region of a fitting body which is part of the fitting system. In this case, a guide pin, which is provided in a side region of the closure flap, can be brought into contact with the damping device, and the damping device can be acted upon by a force exerted via the guide pin weight of the closure flap during transfer of the closure flap in an end position via a damping section. In this case, the damping device exerts on the guide pin a counterforce which is smaller than the force exerted by the guide pin on the damping device weight. The fitting system according to the invention is characterized in that the fitting body in the end region has an undercut in cross-section and is designed to be elastic in the region of the undercut, so that the damping device is detachably connected to the fitting body by means of the undercut. "Undercut" means that the side walls, which limit the receiving space for the damping device, engage behind the damping device and thereby fix it in the receiving space. Furthermore, in the fitting system according to the invention, a position adjustment device for the damping device is embedded in the fitting body and designed to adjust the position of the damping device relative to the fitting body, wherein the damping device abuts the position adjusting device.

Due to this design of the fitting system a simple replacement of the damping device is possible. Furthermore, no additional holding device for the damping device in the fitting body is necessary, so that the fitting body can be produced inexpensively. Furthermore, different damping devices with different degrees of hardness or with different damping forces can be used. The fitting system according to the invention can thus be used for different closure flap geometries and closure flap weights, since only the damping device has to be replaced and adapted to the corresponding closure flap.

By means of the fitting system according to the invention, which can be completely or at least predominantly embedded in the wall, in particular side wall of the piece of furniture, the storage space of the piece of furniture is reduced only to a small extent or not at all. Furthermore, the closure flap can move in a damped, ie braked way, in particular by its weight alone, in its end position. This allows a very smooth movement completion and an almost noiseless transfer of the flap in its final position. This end position is preferably the closure position, but may also be the open position. The cost of the hardware system can be kept low. Due to the guidance of arranged in the side regions of the flap guide pins in the angled or curved guide slot no complicated linkage between the flap and the fitting systems is necessary. There no linkage is used for coupling the fitting system with the closure flap, and since the damping device is recessed in the region of one end of the fitting body, the damping device is not projecting laterally beyond the fitting body. The fitting system thus has only a small depth and can be embedded in the walls, in particular side walls, of the piece of furniture without undesirably weakening or breaking the walls.

By adjusting the position of the damping device via the position adjustment device, the position of the closure flap can be adjusted in its end position, so that, for example, in the end position the closure flap is arranged over its entire circumference at a uniform distance from the body of the piece of furniture.

The position adjustment device can be realized for example by an eccentric, which is integrated below the damping device in the fitting body or inserted into a recess in the wall of the piece of furniture. The eccentric in this case has an axis about which the eccentric is rotatably mounted. By rotation of the eccentric about this axis of rotation due to the contact of the eccentric with an end face of the damping device, the position of the damping device is varied relative to the fitting body.

Preferably, the damping device comprises a damping cylinder with an extendable piston rod, and the damping device is actuated by the piston rod is inserted by means of the guide pin of the closure flap in the damping cylinder or pulled out of this.

Such a damping device provides a defined damping distance and a defined counterforce or damping force. The damping is usually carried out in that when moving the piston rod, a fluid is displaced within the damping cylinder and / or a spring arranged within the damping cylinder is deformed. The piston rod is biased so that when the guide pin of the flap is removed, it is pushed back into its original position.

Preferably, the end position of the damping device also determines the end position of the closure flap. In this case, no separate end stop is required for the flap. However, it is also conceivable that the closure flap is decoupled shortly before reaching its end position of the damping device and is thus moved with increased closing force against an end stop.

Preferably, the fitting body has a substantially U-shaped cross section with two side walls, a rear wall and an open side oriented towards the front of the fitting body. The guide slot is formed by two opposing inner surfaces of the side walls. As a result, the fitting body is very compact and can also be embedded in a correspondingly provided recess of a side wall of the furniture, so that the storage space loss of the Furniture is minimal.

Preferably, the cross section of the fitting body in the region in which the damping device is provided, substantially equal to the cross section of the fitting body in which the guide slot is provided. As a result, the fitting body can be designed in a particularly simple manner and therefore produced in a particularly cost-effective manner. The transverse extent of the cross-section of the fitting body in the region in which the damping device is provided can either be greater or smaller than the transverse extent of the cross-section of the fitting body in the region in which the guide slot is provided, so that existing damping devices can be used ,

In the following description, it is assumed that an unillustrated piece of furniture, in particular a cabinet or container, comprises two vertically oriented side walls, a horizontally oriented base plate and a horizontally oriented ceiling plate. The side walls, the bottom plate and the ceiling plate enclose a storage space which can be closed by means of a closure flap 200. In this closed position of the closure flap 200, this is oriented perpendicular to the side walls, the bottom plate and the ceiling plate of the cabinet or piece of furniture.

FIG. 1 shows an embodiment of the fitting system according to the invention for guiding a closure flap 200 in a side wall such a piece of furniture. In the opposite side wall of the furniture, a corresponding, mirror-image designed fitting system is provided so that the closure flap 200 is guided accordingly in its two side areas.

The fitting system comprises a fitting body 100, which in FIG. 1 L-shaped with a first leg 112 and a second leg 114 is configured. The fitting body 100 can be embedded in a recess of a side wall of the furniture. It is assumed in the following that the fitting body 100 is inserted into the side wall of the piece of furniture so that the first leg 112 extends parallel to a horizontal upper edge of the side wall, so that in the assembled state, the first leg 112 also has a horizontal orientation. The second leg 114 then runs parallel to a vertical front edge of the side wall, so that the second leg 114 in the assembled state and with a corresponding orientation of the piece of furniture has a vertical orientation.

The in FIG. 1 illustrated fitting body 100 has a substantially U-shaped cross-section. FIG. 4 shows a section in the plane II of the fitting body 100. The U-shaped cross-section has two side walls 102, 102 ', a rear wall 104 and an oriented toward the front of the fitting body 100 open side 106. In this case, two opposing inner surfaces 103, 103 'of the two side walls 102, 102' form a guide slot 111 of the fitting body 100. The guide slot 110 runs in the in FIG. 1 shown fitting body 100 both in the horizontally oriented first leg 112 and in the to perpendicularly extending second leg 114, so that the guide slot is angled in an L-shape.

The guide slot 111 is configured to receive guide pins 210a, 210b which are mounted in side regions 202 of the closure flap 200 and protrude laterally beyond the closure flap 200. Like from the FIGS. 1 to 3 As can be seen, the guide pins 210a, 210b are S-shaped. One end of the guide pins 210a, 210b is thereby guided in the guide slot 110 of the fitting body 100, while the other end of the guide pins 210a, 210b is fastened in a bracket element 211, for example made of plastic or metal, which is anchored in the side area 202 of the closure flap 200 and at least partially embedded in this.

In the presentation of the FIG. 1 the closure flap 200 is in an initial position or in an open position, in which the two guide pins 210a, 210b are guided in the upper, horizontally oriented first leg 112 of the fitting body 100. In this position, the flap 200 is horizontally aligned and disposed near the bottom of the ceiling panel of the furniture.

Due to the U-shaped cross section of the fitting body 100, this can be used in correspondingly provided recesses of the side walls of the piece of furniture, so that the fitting system does not or only slightly protrudes from the inner surface of the side wall of the piece of furniture. So that the fitting system is not used arbitrarily deep in the correspondingly provided recesses of the side walls of the furniture, are pads 108th provided at the fitting body 100, which extend approximately perpendicular to its side walls 102, 102 '.

In the in FIG. 1 horizontally oriented first leg 112 of the fitting body 100, a mounting base 101 is provided, which is inserted into a corresponding recess of the side wall of the furniture and can be screwed to the side wall.

The fitting system further comprises a damping device, which is formed by a damping cylinder 120 with an extendable piston rod 122. The damping device 120, 122 is inserted into the fitting body 100 in the region of one end 100 'of the second leg 114. At the free end of the piston rod 122, a damper head 124 is mounted with an enlarged compared to the cross section of the piston rod 122 cross-section. The piston rod 122 and the damper head 124 protrude into the guide slot 110 of the fitting body 100.

FIG. 1a shows a side view of a portion of the second leg 114 of the fitting body 100. The piston rod 122 and the damper head 124 protrude into the guide slot 110, since the piston rod 122 is in an extended state.

FIG. 2 shows that in FIG. 1 shown fitting system, wherein the closure flap 200 in an intermediate position between the in FIG. 1 shown initial position and an end position is. In the intermediate position of the closure flap 200, which is achieved by pulling the closure cap 200 out of the body of the piece of furniture and by subsequently lowering the closure flap 200 is, is the guide pin 210 a in the second leg 114 arranged guide slot 110, whereas the other guide pin 210 b is guided in the arranged in the first leg 112 guide slot. Due to this arrangement of the guide pins 210a, 210b in the guide slot 110, the shutter 200 has an oblique orientation. At this time, the orientation of the shutter 200 changes depending on the relative positions of the guide pins 210a, 210b in the guide slot 110.

FIG. 3 shows that in the FIGS. 1 and 2 shown fitting system, wherein the closure flap 200 is in an end position. The end position of the closure flap 200 is achieved in that the closure flap 200 from the in FIG. 2 shown intermediate position is pulled slightly further down in the direction of the bottom plate of the cabinet / pressed, whereupon the flap 200 slides alone by their weight in its closed end position. In this case, the guide pin 210a moves toward the damping device 120, 122, and the other guide pin 210b is guided in the guide slot 110 arranged in the first leg 112 in the direction of the guide slot 110 arranged in the second leg 114. Before reaching the end position of the closure flap 200, the guide pin 210a of the closure flap 200 comes into contact with the damper head 124. A weight force of the closure flap 200 is exerted on the damper head 124 and thus on the piston rod 122 via the guide pin 210a. Due to the weight of the closure flap 200, the piston rod 122 is inserted into the damping cylinder 120. The damping device exerts on the guide pin 210 a from a counterforce that is smaller than the weight force applied by the guide pin 210a to the damper 120, 122 is such that the shutter 200 is transferred to the end position at a reduced speed.

FIG. 3a shows a side view of the second leg 114 of the fitting system, wherein the damping device is in the maximum collapsed position and thus in its end position. The damper head 124 forms an end stop for the closure flap 200 in this end position, which is then in its vertical closure position.

That in the Figures 1 to 3a The fitting system 130 also has a position adjustment device 130 in the form of an eccentric 130. The position adjustment device 130 is embedded in the fitting body 100 and is configured to adjust the position of the damping device 120, 122 in the fitting body 100. For this purpose, the damping cylinder 120 is received longitudinally displaceable in the fitting body 100. The Positionseinstelleinrichtung 130 is disposed immediately below the damping cylinder 120 so that it rests with its lower end face on the Positionseinstelleinrichtung 130. Due to the eccentric configuration of the position adjustment device 130, the position of the damping cylinder 120 in the fitting body 100 can be varied by rotating the position adjustment device 130 about an axis of rotation oriented perpendicular to the rear wall 104 of the fitting body 10, thereby also adjusting the position of the closure flap 200 with respect to the piece of furniture can be.

The Positionseinstelleinrichtung 130 is inserted via a laterally disposed recess 109 of the fitting body 100 in the fitting body 100.

In the Figures 1, 1a and 2 It is shown that the fitting body 100 in the end region 100 'at the height of the position adjusting device 130 facing away from the end of the damping cylinder 120, a shoulder 107 is provided. Due to the shoulder 107, the fitting body 100 has a smaller depth extent in the end area 110 'than in the remaining area of the fitting body 100. In the end area 110, a cover can be mounted in front of the damping cylinder 120, so that the damping cylinder 120 is not visible from the outside , The support 108 of the fitting body 100 preferably merges flush into the corresponding cover.

Out FIG. 5 It can be seen that the fitting body 100 has an undercut in the end region 100 'in cross-section, so that a first transverse extent Q1 of the open side 106 of the fitting body 100 is slightly smaller than a diameter D of the damping cylinder 120. Furthermore, a second extent Q2 of the fitting body 100 at least partially equal to or larger than the diameter D of the damping cylinder 120, so that the damping cylinder 120 between the side walls 102, 102 'finds room. A part of the fitting body 100 in the region of the undercut and thus in the end region 100 'is designed to be elastic, so that the damping device in the form of the damping cylinder 120 and the piston rod 122 can be pressed into the U-shaped profile of the fitting body 100 and the damping device 120, 122 detachable with the fitting body 100 by a snap connection connected is.

Due to the releasable connection between the damping device 120, 122 and the fitting body 100, the damping device can be replaced by another damping device, or a fitting body can be retrofitted with a damping device 120, 122. The damping device 120, 122 can be tilted out of the fitting body 100 about an axis of rotation, not shown in the figures, perpendicular to a side wall 102, 102 'of the fitting body 100.
