Abstract

A damping device used for buffering motion energy and/or impact of mobile furniture in relative motion, especially for buffering motion of a drawer guided and on a guiding element, comprises a damping means fastened to a stationary or mobile furniture part. In order to avoid the occurrence of an undesirable rebound on a furniture part or the like, while enabling the furniture part to perform a regular closure movement when the furniture part is performing a rapid movement or moving towards the closure position, the stop part comprises a portion with a spring elasticity or capable of absorbing energy or damping means.

Description

Cushion the kinetic energy of mobile furniture parts relative motion and/or the device of bump

Technical field

The present invention relates to the kinetic energy of the furniture parts relative motion that a kind of buffering is guided and moves and/or the device of bump, in particular for being buffered in the motion of the drawer that is guided on the guider, this device has a buffer gear that is fixed on a fixed-site or the movable furniture parts, and the parts that furniture parts absorbs motion or bump move towards a backstop of another parts.

Background technology

By EP1 120 066 A2 and for example known drawer slide with drawn-back device of EP01 111 420.4, this guider is furnished with buffer gear, and this device moves the effective range the inside that the drawer kinetic energy that pushes is buffered in drawn-back device with impacting type.For the furniture parts that relatively moves and especially kinetic energy may occur and can not be cushioned mechanism fully and absorb for the drawer of above-mentioned form, therefore be closed or be drawn into before device moves its closed position at furniture parts or drawer, may produce resilience.

Summary of the invention

Therefore the objective of the invention is, a kind of device of above-mentioned form is provided, when the furniture parts move with fast speed or clash into, can prevent that in this device furniture parts or like from producing the resilience of not expecting and can also realize normal closing movement thus on its closed position direction.

Realize therefrom for this purpose of device of above-mentioned form according to the present invention, backstop by one flexible or power consumption parts or a buffer gear formed.Because for according to device of the present invention, described backstop is flexible, power consumption or is designed to buffer gear, so also can cushion the quick of mobile furniture parts and impacting type motion, and have only a buffer gear that moves with respect to fixed stop effectively not cushioned and to absorb.

Described backstop is made up of a vibration damping slide plate or push rod.

Described slide plate preferably by a stage clip vibration damping that is arranged in the cylinder blanket, can adjust by bolt by the pretightning force of this stage clip.

According to another embodiment of the present invention, described backstop is made up of a damper piston-cylinder unit.

According to a kind of preferred embodiment, constitute the elasticity of described backstop or consume energy parts constitute the braking of buffer gear of described backstop or cushioning effect less than the cushioning effect of first buffer gear.

First buffer and/or elasticity or power consumption parts or second buffer gear can be fixed on the support plate, and this support plate is connected and/or the power transmission connection with described furniture parts or a guide rail shape.

According to another embodiment, described support plate and described furniture parts or guide rail welding or bolt are connected.

The specific embodiment

At drawer slide right side vertical view shown in Fig. 1 and 2.Unshowned drawer slide left side mirror image equally constitutes.

Drawer slide is made up of a support rails 1, and its vertical leg 2 is fixed on the sidewall 4 of a furniture parts by method shown in Figure 3.The horizontal support legs of support rails 1 is converted into Z-shaped on its edge by right angle corner.The supporting leg of turning projection is surrounded by a pull out guide rail 5 by method shown in Figure 3, and this pull out guide rail is connected with method shown in Figure 3 limit portion with drawer 6 bottoms.Horizontal sides marginal zone 7 roller bearing by illustrating between the horizontal leg of the box-shaped bent section of pull out guide rail 5 that turns from support rails 1 supporting leg of projection.The drawer slide here is corresponding to by the known drawer slide of EP01 111 420.4, and more detailed description can be referring to the document.

Be furnished with a drawn-back device 9 by the drawer slide shown in Fig. 1 to 3, this device corresponds essentially to by drawn-back device known among the EP01 111 420.4.

On the horizontal galianconism parts 10 of support rails 1, fix the buffer gears of forming by a piston-cylinder unit 12 by support plate 11.

For support plate 11 being fixed on the galianconism parts 10 of support rails, these galianconism parts are provided with two rectangle open-works 13 that the space certain distance is provided with on center line with method shown in Figure 1, its side 14 towards the back edge wedge shape of open-work 13 extend to together.Support plate 11 is provided with the tongue piece 16 that is made of towards material (Freischnitte) 15 open type with open-work 13 mutual places at regular intervals, this tongue piece becomes the end portion 18 at turning to be formed with one with this part by the part 17 of a projection, and this end portion tilts for the plane of support plate 11 with acutangulating.There is inclined plane 19 at the edge of end portion 18.For support plate 11 being fixed on the galianconism parts 10 of support rails 1, the tongue piece 16 to 18 of hook-type bending injects open-work 13.Then with on the direction of support plate arrow A in Fig. 1 towards open-work 13 back extreme direction roof pressures.The side of hook part 17 is hung on the lateral edges of open-work 13, because equal or more preferably greater than the distance of open-work 13 sides 14 at the width of the right part of open-work 13 part 17.Tilt on support plate 11 directions because link up with 16 end portion 18, so these end portions also can be engaged on open-work 13 edges of galianconism parts 10 with tightening.

The buffer gear cylinder body of forming by piston-cylinder-unit by an end right-angle bending lug 20 and the crooked tongue piece 21 of circular arc of a bent projection from the support plate 11 be fixed on the support plate 11, crooked tongue piece local shape connects and chucking ground surrounds the cylindrical part of buffer gear.In order to improve buffer gear cylindrical part fixing on support plate 11, this support plate is furnished with

projection

24,25, at the base profile outline line of this projection upper support cylindrical part.

Pull out guide rail 5 has a backstop 26, the push rod cap 27 of collision buffering mechanism 12 when this backstop pushes drawer 6 along the arrow A direction.

Backstop 26 is made up of cylinder blanket 30, stage clip 31 tensioning between the enlarged width end portions of the push rod 33 of supporting header board 32 and adjustment bolt 34 that is screwed into cylinder blanket 30 base plates in shell.Can adjust the pretightning force of stage clip 31 by adjusting bolt 34.Cylinder blanket 30 is connected with pull out guide rail 5 by a fixed head or fixture.

Buffer gear 12 and the backstop 26 with push rod 33 and slide plate 32 are fixed on support rails 1 and the pull out guide rail 5 like this, make the drawer that acts on the closed position on direction A impinge upon drawn-back device and draw in the terminal of motion and be cushioned.The spring force of drawn-back device 9 is big like this, makes this power move two push rods 28 and 33 to closed position shown in Figure 2 at leisure after bump is cushioned.

The difference of Fig. 7 to 12 embodiment and Fig. 1 to 6 embodiment is, described backstop 26 is made of a buffer gear, and this mechanism is basic identical with the structure that is fixed on the buffer gear 12 on the support rails 1.

Second buffer gear 40 that constitutes backstop 26 is fixed on the support plate 41, and the lug 42 that this support plate is provided with an end right-angle bending is used for bearing plate and has the elastic tongue piece 43 of a side arc-shaped bend to be used for the cylindrical part that local envelopment constitutes second buffer gear 40 of backstop.Support plate 41 has the cylindrical part of

projection

44,45, second buffer gear 40 that stamping-out comes out to lean these projections at profile outline line place.Support plate 41 has turning lug 46 in addition, and this lug is used for by welding or other method support plate 41 being fixed on pull out guide rail 5.
