Description

Shell handle with operable shutter

The invention relates to a shell handle, in particular for a piece of furniture with at least one movable furniture part, comprising a housing with at least one engagement opening, wherein the housing is connectable to the movable furniture part of the furniture or the housing is at least partially worked out of the furniture part and wherein the housing has a partially in the engagement opening projecting stop, and a movable relative to the housing shutter, which is arranged in the housing and which rests against the stop of the housing when not in operation. Furthermore, the invention relates to a furniture part, which has a shell handle and a piece of furniture with such shell handles or furniture parts.

Known are such depressible shell handles, for example, from DE 20 2006 005 648 Ul Here, the shutter is supported by two springs and pressed by them against the stop. The disadvantage here is that the springs can be very rigid, whereby the operation becomes unwieldy. Furthermore, by frequent use, the spring force can be adjusted or decrease, causing the

Shutter is no longer optimally pressed against the stop and thus the visual impression of an almost continuous surface is no longer given. Even with very rigid suspension set the opening - especially for children - be dangerous, as by an immediately spring back spring between

Stop and shutter can be clamped. Also, the attachment and use of springs is a relatively expensive and expensive form of depressibly holding or placing a shutter in a shell handle.

Furthermore, from AU 597 440 B2, a shell grip is known, in which a pivotable closure flap is arranged. This flap is acted upon by a kind of leaf spring. This means that upon actuation of the flap in the direction of the interior of the shell handle, the leaf spring is flattened, while the contact point between the leaf spring and flap in the direction of the axis of rotation of the flap on the shell handle wanders. It is disadvantageous that you can not impress at any point of the flap, but only in a remote from the axis of rotation region of the flap. The object of the invention is to provide a shell handle which avoids the disadvantages described above, whereby a prior art improved shell grip is specified.

This object is achieved in that at least one elastically bendable return element in the form of a suction cup or Spreizkorbs, preferably made of plastic, is arranged on the rear side of the shutter, which presses the shutter against the stop when not in operation, whereas the shutter can be moved away from the stop when actuated is, wherein the restoring element deformed against the inherent rigidity, preferably flattened and / or spread, is. This embodiment is less expensive than the prior art and can avoid the pinching of fingers mainly by the, after operation relatively slowly, moving back into the stop position shutter.

According to one embodiment, it is provided that the housing comprises an integral with the housing bottom element on which the restoring element is supported. Alternatively, however, it can also be provided that the housing comprises a separately executed bottom element, which is connected to the housing. Different embodiments of the combination options of housings and bottom element are shown in figures below, wherein also shows a figure., That the bottom element is clipped on the housing via a snap-in connection.

A possible embodiment provides that the restoring element bears against the bottom element or is connected thereto, preferably glued. As a result of the restoring elements present here, which will be explained in more detail later, in contrast to the prior art, there is an unobtrusive mounting of the restoring elements. If springs are used as restoring elements as in the prior art, they must be fixed with respect to the shutter or the housing, since otherwise they could adversely affect the actuation of the Verschfussbfencfe or could block this operation by tipping over or pinching the spring. A preferred embodiment of the present invention mussel handle provides that the restoring element via abutment points or one or more abutment surface (s) such on the shutter or on the bottom element of the housing rests, that upon actuation of the shutter, the abutment points or abutment surface (s) at Non-actuation of different sized area on the shutter or surrounded on the bottom element of the housing. Thus, the return element does not have to be in fixed connection with the housing or the floor element or the shutter, but it can be relatively freely angeordent in the housing of the shell handle and limited only by bottom element, housing and shutter in the movement.

An exemplary embodiment provides that the surface surrounded by the abutment points or abutment surface (s) on the shutter is greater when the shutter is actuated than when it is not actuated.

Furthermore, it can be provided that the abutment points or abutment surface (s) of the restoring element abut circular or circular section on the shutter, wherein the radius of these circles or circular sections changed upon actuation, preferably increased.

A first embodiment of this invention mussel handle and its restoring element provides that the restoring element is designed as a suction cup, wherein preferably the open side of the suction cup rests against the shutter and presses the shutter against the stop when not operated. Alternatively, however, it could also be provided that the open side of the suction cup points in the direction of the bottom element of the housing or bears against it.

This embodiment of the return element causes the suction cup to suck against the closure panel when it is actuated, and negative pressure is created between the suction cup and the closure panel.

A shutter which slowly moves back into the stop position is thereby achieved in that the surface of the suction cup facing the suction cup Shutter is formed such that the negative pressure between the suction cup and shutter dissipates by infiltration of air after a short time.

A short time in this context means a period of a few seconds, for example, of about 10 seconds, until the shutter rests again after pressing the stop of the housing. The necessary infiltration of air is guaranteed by the fact that the suction cup facing surface of the shutter is roughened, whereby air penetrates between the shutter and adjacent suction cup. In experiments, it has been found that a thin sheet of paper, which is applied to the side facing the suction cup, already supports the infiltration of air and thus the slow dissolution of the negative pressure and moving the shutter due to the inherent rigidity of the return element or suction cup in Direction rash effected.

As already indicated above, according to one embodiment it is provided that the surface surrounded by the contact surface of the suction cup on the shutter is greater by approximately 5 to 10% when the shutter is actuated than when it is not actuated. In this regard, it has been shown in tests that a suction cup used by way of example, when not operated, has a diameter of 43 mm, whereas when operated, this diameter is 46 mm. This leads to an increase of the contact surface of the suction cup on the shutter by about 7 percent.

Upon actuation, the adjacent surface of the suction cup moves from each other or wander apart from the suction cup midpoint. The abutment surface thus does not remain constant during actuation on the shutter and also the abutment points do not remain constant to each other.

A second alternative possibility according to the invention for specifying a restoring element suitable for the invention is that the restoring element is designed as a spreader cage. This Spreizkorb has at least two resilient or spring-loaded Spreizfortsätze, wherein the Spreizfortsätze flower-shaped or projecting radially from a common central element. Depending on the design of this Spreizkorbes (see Fig. 37 and 38), it is advantageous if the Spreizfortsätze at an angle between 30 ° and 85 °, preferably between 60 ° and 80 ° from the plane of the central element or bottom element in the direction of shutter or project the Spreizfortsätze at an angle between 95 ° and 150 °, preferably between 100 ° and 120 ° protrude from the plane of the central element or floor element in the direction of shutter.

When using a Spreizkorbes is thereby provided that the direction away from the central element ends of the Spreizfortsätze abut the shutter panel in a circular section. Preferably between 4 and 10 expansion processes with central element can form the expansion basket. Thus, in contrast to the suction cup no continuous circle forms the contact surface on the shutter or on the bottom element.

In general, the restoring elements preferably have a substantially trapezoidal cross-section, wherein one of the two parallels - preferably the longer of these parallels (base) - is missing, as a result of which a restoring element open in cross-section is created. The two legs are connected to the remaining parallel in such a way that an angle change between the parallel and the respective legs takes place by actuation of the restoring element. Not to be excluded, of course, all geometric shapes (U-shaped, W-shaped, N-shaped, Y-shaped, M-shaped, Schüsseiförmig, etc.), which allow a flattening and thus caused spread. In particular, those forms are favorable, which cause an enlargement or reduction of the surface surrounded by the contact surface. Thus, an S-shaped cross section of the return element for the inventive execution of a shell handle is indeed possible, however, surrounds in this embodiment, the contact surface no area on the shutter or the bottom element, but forms a straight line. This is similar to a spring and requires in particular a more complex fixation or stabilization in the housing or on the shutter to not affect the operability. A cross-section in the form of a horizontal S forms two mutually parallel abutment surfaces, whereby a spreading of the return element is made possible. For the suction cup comes as a material silicone, rubber or soft PVC with a hardness of 70 Shore A in question, for example TPE (Santoprene from Exxon), MPR (Alcryn from APA) and EVA (Elvax from DuPont ) can be used.

For the Spreizkorb are slightly harder plastic materials, such as polyoxymethylene (POM), polypropylene (PP) and polyamide (PA, PA6) are preferably used. By adjusting the material to the desired inherent rigidity of the expansion basket thus the return movement speed and thus the movement of the shutter in the direction of stop on the housing is adjustable.

Preferably, it can be provided that two or more elastically bendable restoring elements, preferably made of plastic, are arranged on the rear side of the shutter, which press the shutter against non-actuation against the stop, whereas the shutter is moved away from the stop when actuated, the return elements against the Stiffness deformed, preferably flattened and / or spread. Depending on the size and shape of the desired shell handle can thus serve several restoring elements, such as suction cups or Spreizkörbe as restoring elements for the shell handles.

An advantageous embodiment may provide that in a movable furniture part a bore is formed, preferably milled, that this forms the housing together with stop for a shutter.

A preferred embodiment further provides that the bore is designed as a through hole and this is covered by a mounted on the back of the movable furniture part, preferably screwed there floor element.

Alternatively it can also be provided that the housing of the shell handle is inserted in a bore of the movable furniture part, preferably glued or screwed or the housing of the shell handle is mounted in a through hole or blind hole of the movable furniture part. Another important aspect of this invention, for which protection is sought, is a piece of furniture with a shell handle according to one of claims 1 to 21. One possible embodiment may provide that the furniture part, for example a door leaf, has a frame passing through the housing and the bottom element is formed, in which a preferably plate-shaped, adapted to the frame, shutter is operably disposed between a stop of the housing and return elements. The housing of this shell handle can be movably mounted on a piece of furniture, for example by means of hinges, the movement being carried out as usual in the case of shell handles by pulling on the stop.

Protection is also sought for a piece of furniture, which has a shell handle according to the invention or a just mentioned furniture part.

Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show in it

Reset element. Fig. 1 shows the cross section of a shell handle 1, which is inserted into a furniture part 3. This shell handle consists of a housing 4, a shutter 7, which abuts against the stop 6 of the housing, and a return element 8, which is designed as a suction cup 8a. This sucker 8a is located at the attachment point 11 on the shutter. This Fig. 1 shows the shell handle 1 when not operating the shutter. 7

In contrast, Fig. 2 shows the operation of the shutter 7, whereby the suction cup 8a is flattened and prevails in the area between the suction cup 8a and shutter 7 negative pressure and these are held together. By corresponding roughness of the shutter surface air can penetrate into the gap between the shutter 7 and suction cup 8a air, whereby the suction cup 8 by its inherent rigidity, the shutter 7 moves back towards the stop 6 of the housing 4 and thereby closes the engagement opening 5.

FIGS. 3 and 4 show the tilting mobility of the shutter 7 as a function of the point of engagement or the actuation point of the shutter 7.

Fig. 5 shows a suction cup 8a from below, Fig. 6 shows this in a cross section and Fig. 7, the suction cup 8a in a view.

8 to 11 show the same cross sections as Figs. 1 to 4, wherein instead of the suction cup 8a of Spreizkorb 8b is used. This Spreizkorb 8b is, as shown in Fig. 9, flattened and spread by actuation of the shutter, whereby the Spreizfortsätze 12, which bear against the abutment surfaces 11 on the shutter, are pressed apart. The spreading extensions 12 start from a common central element 13 which can be fastened to the housing or to the floor element or furniture part. By using a corresponding material for the Spreizkorb 8b, the speed of the return movement of the shutter in dependence on the inherent rigidity of the material used and thus the Spreizkorbes 8b can be adjusted or regulated accordingly.

Fig. 12 shows clearly the flower shape or radii of the Spreizkorbes 8b, which is shown in this case from below. Here go from the central element 13 eight Spreizfortsätze 12 or stand from it. Fig. 13 shows a cross section through the Spreizkorb 8b and Fig. 14 is a view of the Spreizkorbes. In the latter, it can be seen that the Spreizkorb 8b consists of areas of a truncated cone-shaped body.

Figs. 15 and 16 show views of the illustrations of Figs. 1 and 2, wherein additionally a bottom element 9 can be seen. Fig. 17 shows the housing 4, which is insertable with the shutter 7 and the suction cup 8a in a recess of the furniture part 3, wherein the housing 4 has retaining hooks 18 all around, whereby it better holds in the recess of the furniture part 3.

In a similar manner, FIGS. 18, 19 and 20 show embodiments of clamshell handles 1, wherein spreader baskets 8 b are used as return elements 8.

FIGS. 21 and 22 show alternative forms of clamshell handles 1, in which a plurality of return elements 8 can be arranged.

Figures 23 and 24 are exploded views of such clamshells having multiple return elements 8. In this case, the housing 4 is additionally formed by side elements 4a, whereby the simple and uncomplicated assembly of the shell handles 1 is made possible by this.

FIGS. 25 to 28 now show embodiments of clamshell handles, which are designed as a furniture part 3, in particular as a door leaf 15. Here, the housing 14 together with the bottom element 9 forms the frame 14 of the door leaf 15, wherein a plate-shaped shutter 7 is arranged in a pass-shaped manner between the stop 6 and the return elements 8. The return elements 8 can in this case again be embodied as a suction cup 8a or as a spreader basket 8b.

FIG. 29 shows a through bore 16a through the furniture part 3. In this furniture part 3 is then (see FIG. 30) the housing 4 inserted from above, which holds at least on the retaining hooks 18 on the furniture part 3. Then, from below, the shutter 7 and then the suction cup 8 a is used. Finally, the rear side of the furniture part 3 is covered by the floor elements and connected by screws 10 to the housing 4. Fig. 31 shows a blind bore 16b in the furniture part 3, in which (see FIG. 32) the housing 4, the suction cup 8a and the shutter 7 are inserted and then held with screws 10 on the furniture part 3.

Fig. 33 shows a through hole which is milled into the furniture part 3, wherein the stopper 6 projects into the passage opening 5, whereby no separate housing is necessary. Subsequently, as shown in Fig. 34, the shutter 7 is brought into abutment. Below this, a suction cup δa and then the bottom element 9 is attached, which holds on the furniture part 3 via screws 10.

In Fig. 35, a bore 16 in the furniture part 3 is shown. As can be seen further in FIG. 36, a bottom element 9, which is fixed on the furniture part 3 via the screw 10, is first inserted into this bore 16. This bottom element 9 in this case has all around a latching lug 9a, via which a latching nose 4a of the housing 4 can be clipped. Before clipping, however, the suction cup 8a and the shutter 7 should be used.

Fig. 37 shows a cross section of the Spreizkorbes 8b with the central element 13 and the Spreizfortsätzen 12, wherein the Spreizfortsätze 12 protrude at an angle of 68 ° from the central element 13. Alternatively, as shown in FIG. 38, the spreading projections 12 could project at an angle of, for example, 112 ° from the central element 13. As a result, in contrast to the other embodiment, the area A2 would decrease on actuation of the shutter 7, which is surrounded by the abutment points 11. These angles can be chosen very freely and depend strongly on the material used and on the desired return properties.

FIG. 39 schematically shows the prior art in which a housing 4 and a shutter 7 are moved by a return member configured as a spring 19. Here, the force of the spring or the force curve after actuation of the shutter 7 is linear or straight.

In contrast, Fig. 40 shows the force course or the movement of the force in the present invention. Here, by way of example, the Spreizkorb 8b be shown, in which after actuation of the shutter 7, the Spreizfortsätze 12 to the Hinged point 20 between Spreizfortsätzen 12 and central element 13 curved or curved and not linearly move upwards. The force thus runs in a circle around the hinge point 20 and not linearly as in a spring or for example in a foam. This force curve is an essential difference between expandable and resilient restoring element.

Fig. 41 shows the abutment surface 11 of a suction cup 8a on the shutter 7 when not operated. Now, when the shutter 7 is actuated, the area A2 increases between the abutment surface 11. Equivalent, this is also the Spreizkorb 8b, as shown in Fig. 42, instead. In this case, the circular section-shaped abutment surfaces 11 surround a smaller area A1 when not actuated than when actuated (area A2). If a spreader basket 8b is used, which is implemented as shown in FIG. 38, the area A2 decreases in comparison with the area A1.

FIG. 43 also shows an alternative embodiment in which the restoring element 8 with the open side is arranged in the direction of the bottom element 9 in the housing 4. In this case, it is also preferably provided that the bottom element has a roughened surface in order to ensure a slow backward movement for the shutter 7 in the direction of the rash 6 when using a suction cup 8a as a restoring element 8.

Thus, the present invention shows a visually appealing shell handle, the engagement opening is covered by a shutter, with handy, simple running, flattened and / or spreadable return elements ensure comfortable handling without jamming and without complicated attachment of these return elements.
