Description

Handle bar for a drawer, especially for a drawer of storage and

Resource means

The invention relates to a handle bar for a drawer, which has a fastening part with which the handle bar can be fastened to a drawer and is provided with a visible part in which information carriers can be attached.

Drawers for cupboards, especially for cupboards that are used as operating and storage equipment in industry, handicrafts and manufacturing, must first and foremost meet high functional requirements. This includes, for example, high mechanical stability, even when the drawers are used intensively. In addition, the drawers should also be ergonomically favorable and simple and inexpensive to manufacture.

All of these aspects must also be taken into account in the handle part of the drawer with which the drawer is pushed in and out by a user from a frame such as a cupboard. A constructive solution has now proven to be advantageous in which the drawer forms a sheet metal front, which can also be part of the front of a cabinet. This type of drawer has a fastening section which is generally connected in one piece to a front of the drawer and to which a handle strip can be fastened. In the grip strips used by the applicant in her products since then, a positive connection between the grip strip and the fastening section is provided for this purpose.

The known handle bar mentioned is essentially made of aluminum. In order to give the front of the drawer a pleasing appearance and to avoid the risk of injury, caps are pushed onto the two end faces of the receiving part, which lie more or less flush against the handle bar.

The handle bar also has a viewing window on its visible side, in which a Labeling strips can be arranged. The label should contain information about the contents of the drawer. To protect the labeling strip, a transparent cellophane strip is inserted into the viewing window.

This previously known handle bar can not satisfy in several ways. In order to obtain a secure attachment of the handle strips, they usually sit so firmly on the receiving part that they can only be replaced with a very considerable effort and using non-standard special tools. In addition, the side plastic caps have to be removed and replaced. The dismantling and assembly effort required to change the labeling strips is also considerable. Eventually the cellophane strips tend to do so

TO V €

The way in which labeling strips have to be inserted and removed from the visible part has found particularly low acceptance among users of drawers. The cellophane and labeling strips must be inserted from the side into the visible part of the handle. Since both strips are not stiff in themselves, this process creates difficulties and is often very time-consuming. Since the labeling strips are elongated paper strips with a low height, they have always had to be labeled laboriously by hand. This also means that labeling strips are rarely changed and their labeling often does not reflect the actual contents of the respective drawer.

The invention is therefore based on the object of providing a solution for a handle strip of a drawer which is more favorable in terms of its usage properties, in particular with regard to the visible part.

The object is achieved according to the invention in the case of a handle bar of the type mentioned at the outset in that the handle bar is provided with at least one snap connection for closing the visible part. In the case of the grip strips according to the invention, it should therefore be possible to open and close the visible part of the grip strip in a suitable manner without the use of a tool due to a snap connection. In addition, the area behind the visible part should be accessible in a few simple steps, advantageously only by releasing the snap connection. Because of the snap connection, there is also a defined closure end position of the visible part, which is easily recognizable as such both visually and haptically by a user.

In a preferred embodiment, the snap connection can have an undercut, into which a projection engages in the closed end position. In order to lead the projection out of the undercut, a resistance must be overcome, for example a restoring force that builds up reversibly.

In a further preferred embodiment, the undercut can run parallel to a longitudinal extent of the grip strip. A secure and yet structurally simple closure can also be achieved in that at least either the undercut or the projection extends essentially over the entire length of the visible part. However, it is preferred if both the undercut and the projection extend over the entire length of the visible part.

If it is to be avoided that a transparent viewing window of the handle bar can be lost, it can be expedient to connect it in one piece to the handle bar. Additional advantages can be achieved here if the connection point is designed to be flexible, so that the viewing window can be opened and closed by a pivoting movement around the connection point. This enables a labeling strip to be inserted and removed from the front in a particularly simple manner. In contrast to known handle strips, the labeling strip does not have to be inserted from the side. Insertion of the labeling strip from the front can, however, also be achieved by the at least one snap connection without an integral connection of the viewing window on the handle bar. If the connection point extends at least substantially over the entire length of the viewing window, the risk of dirt penetrating behind the closed viewing window can also be significantly reduced. The connection point can therefore advantageously be located above the snap connection in the assembled state of the grip strip. A transition from the fastening part to the visible part can be smooth. This means that even the dust that always sits on the handle bar from above has little chance of penetrating behind the viewing window or getting stuck in recesses.

The handle bar is preferably made entirely of plastic, wherein the fastening part and the visible part can have the same or different plastics. PVC, for example, is suitable for the fastening part and can be colored in any color. The visible part should have a window made of transparent plastic, which contains, for example, PVC, Xylex ™ (trademark of the Generei Electric Company), polycarbonate and / or ABS plastic. If the two parts of the handle bar are connected to one another in one piece, it is possible to produce the handle bar in a single continuous casting or extrusion process.

An information carrier to be arranged in the visible part can be part of a printable sheet, for example a paper sheet. This can be segmented, for example by a perforation, a segment corresponding to a labeling strip. As a result, the labeling of a large number of drawers can be carried out very quickly and yet in a visually appealing manner by printing on labeling strips.

Further preferred embodiments of the invention result from the dependent claims.

The invention is explained in more detail with reference to the exemplary embodiments shown schematically in the figures; show it: Figure 1 shows a drawer cabinet in a perspective view.

8 shows a cross-sectional illustration of a further grip strip according to the invention.

The drawer cabinet 1 shown in FIG. 1 has a housing 2 which is closed on all sides except for a front side 3. The front side 3 of the cabinet 1 is essentially formed by the entirety of the front sides 4a of the drawers 4 arranged one above the other in the cabinet. Both the housing 2 and the drawers 4 are made of metal sheets. The drawers can be pulled out of the housing 2 and inserted again in a manner known per se and not shown in detail.

Each of the drawers 4 preferably has four walls 5, 6, 7 which, together with a base plate 8, form a rectangular bearing receptacle 9 accessible from above. 1, the rear wall of the bearing holder cannot be seen when the drawer 4 is pulled out. The storage receptacle 9 is for storing stored goods intended.

The sheet metal designated 5 in FIGS. 1 and 2 serves as the front wall of the drawer 4. It is a one-piece sheet metal bent part which has a horizontal bottom section 10. The latter is provided for connection, preferably for welding to the base plate 8 of the drawer 4. The bottom section 10 merges via a multiply curved section 11 into a front section 12 which has an inclined part 12a and a substantially vertically oriented part 12b.

At its upper end seen in cross section or in a side view, the front section 12 merges into a profiled fastening section 12c. With respect to an outer side, the fastening section 12c forms a kink angle α with the vertical section 12b at a first kink 15. As a result, the fastening section 12c runs obliquely downward from the first to a second kink 16. At the second kink 16, the fastening section 12c is provided with a kink angle β, as a result of which the fastening section is oriented obliquely up to a third kink part 17. At the third kink 17, the front includes a kink angle γ, as a result of which the fastening section is inclined downwards to its free end 18 and is essentially flat.

The handle strip 20 shown in FIGS. 2, 3 and 4 has a cross-sectional shape, which in turn is matched to the cross-sectional shape of the fastening section 12c of the drawer 4. This coordination is carried out by a predetermined geometric design of the handle bar 20 and a material selection that enables the handle bar 20 to be fastened by means of only one snap connection.

For this purpose, a fastening part 21 is formed on the handle bar 20, which extends essentially over the entire area of an inner side 22 of the handle bar 20 opposite the fastening section 12c of the drawer 4. In other exemplary embodiments, the handle strip can also extend only over part of the front of the drawer. With a first end section 23 of the inner side 22 which is concavely curved in cross section, the grip strip 20 lies against the fastening section 12c in the region of the first kink 15 and engages behind it. Here, the grip strip 20 is in contact with the fastening section 12c at two points, the first being located directly in front of the first kink 15 and the second immediately behind. The first contact point is also located in the area of an upper longitudinal edge 24 of the grip bar 20.

At the second end section 25, a groove-shaped receptacle 26 is formed on the inside. Arranged in this receptacle 26 is a lower longitudinal edge 27 of the fastening section 12c which extends over the entire width of the drawer 4. A leg 26a of the receptacle 26 thus engages behind the lower longitudinal edge 27.

The grip bar 20 is also supported on the fastening section by a third contact point 30 on its inside between the second and the third kink 16, 17. An outer side or outer surface 31 of the grip strip 20 runs essentially flat between the first and the third contact point and is oriented approximately horizontally in the assembled state.

Between the third kink 17 and the receptacle 26, the grip bar 20 is concave on its inside 22 and convex on its outside 31, the radii of curvature being identical.

The fastening part 21 of this exemplary embodiment of the grip strip 20 is made homogeneously from a specific plastic, namely PVC, and by an extrusion process.

As part of a visible part 32, a transparent viewing window 33 is provided approximately from the height of the third contact point 30 in the area of the outside of the handle 20. The viewing window 33 is non-detachably connected to the handle bar 20, consists for example of Xylex ™ (brand of the General Electric Company), polycarbonate or the like and has approximately the same curvature as the area of the fastening part 21 that connects it directly opposite. Furthermore, the viewing window 33 extends approximately down to the receptacle 26 of the fastening part 21.

In the area in which the viewing window 33 is extruded in a coextrusion process, the plastics of the fastening part 21 and the viewing window 33 are integrally connected to one another. Because of the materials and / or a suitably thin cross section, a movable hinge 34, a so-called film hinge, can be formed here. By means of the latter, the viewing window 33 can be pivoted about the hinge 34 in the direction of the double arrow 35. It may be advantageous to use a further plastic, which differs from both the fastening part and the viewing window, to form the hinge.

Along its lower longitudinal edge 36 and facing the fastening part 21, the viewing window 33 is formed with an undergrowth 37 which extends over the entire length of the viewing window. The lower longitudinal edge 36 of the viewing window 33 itself is thus arranged at a distance from the fastening part 21 in the closed end position of the viewing window.

The back grip 37 is provided for engaging in a first undercut 38, which is formed by a leg 40 which also extends over the entire length of the viewing window and is approximately T-shaped in cross section. The first undercut 38 faces the lower longitudinal edge of the grip bar.

A second undercut 41, however, is open to the film hinge 34. The fastening part 21 and the viewing window 33 thus form a receptacle 42 between the film hinge 34 and the second undercut 41, into which a label strip (not shown in more detail) can be inserted. In the illustrated embodiment, the receptacle 42 has a curved cross section. The labeling strip is located with its lower longitudinal edge in the second undercut 41. This ensures, on the one hand, a secure and predefined position of the labeling strip in the receptacle 42. On the other hand, this prevents the labeling strip from opening when the Viewing window 33 unintentionally falls out of the receptacle 42.

Finally, the handle bar 20 can have an impact protection (not shown) on each of its two end faces, which covers the front edges of the handle bar 20 and the fastening section 12c. This provided as a replacement for the hitherto usual end caps can advantageously be integrally formed with the handle bar.

In order to mount the handle bar 20 on the fastening section 12c of the drawer, the leg 26a of the groove-shaped receptacle 26 can, for example, first be arranged behind the lower longitudinal edge 27. The grip strip 20 is then pivoted toward the fastening section 12c in a pivoting movement according to the arrow 43. Here, the upper longitudinal edge 24 reaches the fastening section and should be guided over the first kink 15 with the application of a force. The grip bar 20 is elastically deformed here until the upper longitudinal edge 24 comes to lie behind the first kink 15. In this end position, the grip bar 20 has a lower but still an elastic pretensioning force, with which it is held against an unwanted longitudinal displacement on the drawer or even an unwanted disassembly.

To open the viewing window 33, it is possible, for example, to intervene with a fingernail between the lower longitudinal edge of the viewing window 33 and the fastening part 21, and the undercut 37 can be guided out of the undercut 38 by applying a force. An elastic deformation of the viewing window 33 that builds up in the region of the rear grip 37 allows a spring-elastic force to be built up which is reduced again as soon as the rear grip 37 is removed from the leg 40. The viewing window 33 here performs a pivoting movement about the hinge 34. After a labeling strip has been inserted into the receptacle 42, the viewing window 33 can be closed by an opposite pivoting movement. The undercut 37 comes to rest in the undercut 38. The latter two elements are therefore part of a snap connection, with which the Close the viewing window and let it open.

In a further embodiment according to the invention, the fastening part of the handle strip can be made of aluminum. The material of the viewing window can consist entirely or partially of Xylex ™ (brand of the General Electric Company), a transparent and very resistant plastic. The geometric design of the handle bar can essentially correspond to the exemplary embodiment shown in FIGS. 2-4. In contrast to this, however, the viewing window does not necessarily have to be connected in one piece to the fastening part. Instead of the one-piece connection of the viewing window on the handle strip, for example, a second snap connection can also be provided, which corresponds to the type of the snap connection in the region of the lower longitudinal edge.

Such a further exemplary embodiment is shown in FIGS. 5, 6 and 7. In contrast to the handle bar according to FIGS. 2-4, the viewing window 133 is a separate component in this handle bar 120. A hinge 134 of the viewing window which is approximately circular in cross section

133 is arranged in a circular bearing recess 128 provided in the fastening part 121. The bearing recess 128 has an opening width towards the viewing window 133 which is smaller than a diameter or a greatest width of the cross section of the hinge 134. The hinge 134 is thus rotatable in the bearing recess 128 on the one hand about an axis, not shown, which is perpendicular to the plane of the drawing 5 runs. On the other hand, the hinge 134 is fixed against movements in directions that are parallel to the plane of the drawing. The hinge can be used to mount the viewing window 133

134 are inserted into the bearing recess 128 from an end face of the grip strip. Alternatively, it can be provided that the hinge 134 is pressed into the bearing recess from the front and against an elastic resistance.

The viewing window 133 is concavely curved on its upper longitudinal edge 139 and is provided with a rear engagement 137 towards the fastening part (FIG. 7). The fastening part 121, on the other hand, is provided with an approximately circular-arc-shaped profile on a leg 140 running over its entire length. The leg 140 forms one Undercut 138, into which the undergrowth 137 can be pressed and removed in a spring-elastic manner. For this purpose, the viewing window 133 performs a rotary movement according to the double arrow 143 around the hinge 134 (FIG. 6). In this exemplary embodiment too, the viewing window 133 can thus be closed and opened by means of a snap connection.

In addition, in this embodiment, the visible part 132 has a groove-shaped receptacle 142 in the region of the lower end of the viewing window 133, into which the lower edge of a labeling strip can be inserted.

8 shows a further exemplary embodiment of the handle strip according to the invention. Except for the connection between the visible part and the fastening part explained below, the grip bar corresponds to the grip strips explained in connection with FIGS. 1 to 4. 8, the articulation of the visible part 32, which is pivotable relative to the fastening part 21, is produced by a third material which differs from the material of the visible part and the fastening part. The third material provided as an articulated part 44 is located in the region of an upper edge of the visible part. The articulation part 44 connects the viewing part (or the viewing window 33) and the fastening part to one another over essentially the entire length of the grip strip.

The materials of the overall transparent visible part 32 and of the articulation part on the one hand and of the articulation part and of the fastening part on the other hand are each integrally connected to one another. The material bond can be achieved in a continuous casting or extrusion process. In this case too, the articulation part forms a hinge 45, by means of which the visible part can be opened with a pivoting movement around the hinge.

For example, PVC materials can be used as materials for the fastening part and the visible part. For the articulated part, for example, a PVC material which is softer than the materials of the fastening and the visible part can be provided, with which the material required for an elastic deflection can be provided Allow properties of the articulated part to be achieved. Instead of the PVC materials, any other materials can be provided with which the required properties with regard to strength, elasticity and transparency can be achieved.
