Abstract

The damping system for drawer rails comprises a frame (3) fitted on the fixed rail (1). This has a hook-shaped slot (31) with a locking section (32), through which a pin (42) on a slide (4) protrudes, limiting its movement. A spring (6) is mounted between a hook (43) on the slide and a second hook (51) on the on the frame. A compression damper (7) is mounted on the frame and attached to the slide. This slows the movement of the slide if the pin comes out of the slot.

Description

The The invention relates to a Schließdämpfungsmechanismus for one Slide rail, in particular to e.g. Drawers, barriers and the like Slide rails application finds. In this case, an anti-pressure damping device used to the closing speed to reduce the slide rail and thereby possible damage an excessive closing force too prevent.

The Field of application of slide rails is widespread. Mainly serve to do so, to close and open to facilitate the drawers. When the slide rail by compressive force goes back to the starting point, However, it often happens that another sliding motion is due to the inertial force caused by the system. The drawer and the cabinet can not close exactly. To overcome this problem, most companies still put a locking mechanism at the end of the slide rails, and hope through this locking mechanism the slide rails when pushed by the pressure force on the starting point returned be quick to stop and hold on to the effect of automatic closing function to reach. This is the situation because of the inertial force the drawer does not close exactly, eliminates and meets the requirements for closing the furniture drawers Fulfills.

• 1. Um die Wirkung der schnellen Fixierung und engen Schließung der Rutschschiene zu erreichen, werden hauptsächlich Federn eingesetzt, um eine schnelle Positionierung der nach hinten schließenden Schubladen zu erzwingen. Gleichzeitig werden Federn mit höherer Federkraft verwendet, um zu garantieren, dass die Rutschschiene nach längerem Gebrauch immer noch die automatische Schließwirkung beibehält. Aber durch die hohe Geschwindigkeit der sich schließenden Schublade werden insbesondere bei sich wiederholenden Einsätzen durch die Stöße Beschädigungen der Rutschschiene auftreten. Dies wiederum verringert die Lebensdauer der Rutschschiene.
• 2. Durch die Eil-Schließfunktion der Rutschschienen, bieten sie eine ideale Schließwirkung für Schubladen und Regalschränke. Jedoch, falls der Benutzer seine Kraft während des Schließvorgangs nicht richtig einsetzt, oder wenn die Rutschschiene schief installiert wurde, kann die durch eine schnelle Schließung verursachte Stoßkraft die Schubladen oder den Regalschrank aus Holz oder dünnem Metallmaterial beschädigen.
• 3. Die Stöße der Rutschschiene durch die Eil-Schließung verursachen außerdem viel Lärm. Besonders in der Nacht oder in einem ruhigen Innenraum kann dieser Lärm die Umgebungsstille beeinflussen oder den Nachbarn erschrecken.

However, the above-mentioned construction involves many shortcomings that occur especially in manufacturing and later use.

• 1. To achieve the effect of quick fixation and close closure of the slide rail, springs are mainly used to force rapid positioning of the rear closing drawers. At the same time, springs with higher spring force are used to ensure that the slide rail still retains the automatic closing action after prolonged use. But due to the high speed of the closing drawer, damage to the slide rail will occur, especially in the case of repetitive operations due to the impact. This in turn reduces the life of the slide rail.
• 2. Due to the fast closing function of the slide rails, they offer an ideal closing effect for drawers and shelving cabinets. However, if the user does not use his power properly during the closing operation, or if the slide rail has been installed crookedly, the impact force caused by rapid closure can damage the drawers or the wooden or thin metal storage cupboard.
• 3. The impact of the slide rail caused by the rapid closure also cause a lot of noise. Especially at night or in a quiet interior, this noise can affect the surrounding silence or scare the neighbors.

task the invention is to provide a closing damping mechanism, which avoids the aforementioned disadvantages by the closing speed at the end of the closing process is reduced, so by a smooth-running closing process Locking noise reduced and at the same time the life of the slide rail is thereby extended.

These Task is solved by that a closing damper mechanism for one Rail is created, the pressure damping device at the end the rail has, by which the closing speed of the rail reduced and thus the rail is spared, whereby the life of the Rail extended and the usual closing noise considerably muted becomes.

Around the objective to achieve constructive, is proposed according to the invention, that a frame is provided, which is mounted on a rail base and a guide slot Has. The front side of this guide slot is bent, so that a nip arises. A slider is located at the end of the above frame. A clamping part extends in the slider through the guide slot, to allow the sliding movement of the slider. The slider has at least on one side a first hook. A base at the rear Side of the frame and attached to the rail base has, at least on one side a second hook. According to the invention is at least a spring element is provided which extends between the first hook and the second hook. Furthermore, there is still a pressure damper mounted on the above base and connected to the slider is.

If the clamping part of the slider by the pressure of the slide rail, the nip on the guide slot leaves, In the construction described above, the slider moves on the ground the resilience of the spring element with great acceleration to the rear. Due to the braking effect of the pressure damper, which is designed in the form of a shock absorber can be, the slider then moves slowly to the end position to.

With reference to the 1 . 2 . 3 , and 4 Now, a first embodiment of the invention will be described in detail. The locking mechanism according to the invention is located at the end of the rail base 1 and works with the drawing part 21 the slide rail 2 together. The article according to the invention consists essentially of a frame 3 a slider 4 , a base 5 , two spring elements 6 , a pressure damper 7 and other components. This is the frame 3 , the base 5 and the pressure damper a unit, the latter may be in the form of a shock absorber.

The frame 3 that is on the rail base 1 attached has a guide slot 31 , The front side of this guide slot 31 is curved, so that a nip 32 arises. On the two long sides of the frame 3 extend in the longitudinal direction of the slide extending wings 33 ,

The slider 4 that is at the end of the above frame 3 has at least one passage opening 41 , A trained in the form of a pin clamping part 42 extends through the passage opening 41 and the guide slot 31 to the sliding movement of the slider 4 to enable. On the two sides of the slider 4 there is a first hook each 43 and on the rear side of the slider 4 is an insertion hole 44 available.

The base 5 at the rear of the frame 3 at the rail base 1 is attached, has on both sides in each case a second hook 51 ,

The two spring elements 6 are pressure-resistant springs and are located between the first hook 43 and the second hook 51 ,

The pressure damper 7 Here is a pneumatic cylinder and is on the above basis 5 and is with the slider 4 connected. The pressure damper 7 consists essentially of a cylindrical kettle 71 who is based on 5 is fixed and has a sealed air chamber in its front area. At the rear end of the boiler 71 is an action opening 711 intended. The front end of the boiler 71 is with a closing lid 72 locked. To achieve an effective seal of the boiler end, there is a sealing ring 73 intended. A sliding rod 74 , which has a slightly smaller diameter than the action opening 711 has, protrudes through the action opening 711 in the cauldron 71 , That the boiler 71 remote end of the slide rod sits in the insertion 44 in the slider 4 , That in the kettle 71 located end of the slide rod 74 carries a piston 75 that with several opposing vents 754 is provided. The piston is between a rubber seal 76 and the sealing ring 73 arranged.
