DE2422300A1 - Plastics moulded front plate for drawers - is blow moulded with integral handle formed from double-walled body - Google Patents

Abstract

The front plate and handle for the drawer is blow moulded in one piece as a hollow body with one part curved inwards to form the handle. This front plate is economically produced in that the hollow body is formed as a plastics hose which, in the deformable state, can be inflated into a bubble between the parts of a multipart hollow mould which corresponds to the outline of the hollow body. As the mould is closed the bubble can be compressed against the pressure of inflation. The front plate is preferably a rectangular double-walled pocket-type structure where the inner base defines the depth of the handle groove.

Front piece for drawers

The invention relates to a front piece
for drawers, trains or the like.

In grocery stores, especially though
In drugstores and pharmacies, the goods are usually stored in drawers or in walking trains and used by a large number of people. For easier handling, the drawers or pulls are provided with separate handle strips or handle shells in the case of the wooden version and with molded handle strips in the case of the plastic version. Such front pieces are relatively complicated to manufacture and, especially when they are made from plastic, differ only by changing the molds
Adaptable to taste requirements.

The object of the invention is to create a front piece that is simple and inexpensive in the most varied of ways: design can be produced.

According to the invention, this object is achieved by that the front piece of a one-piece plastic hollow body with at least one arched wall section as a grip groove is formed. This configuration of the front piece according to the invention ensures a secure gripping the same by the user of the drawer or the train and allows a very simple production with the help of Blow molding process in which the hollow body consists of a plastic tube is formed, which in the plastically deformable state between the parts of a multi-part, the outer contour the hollow shape corresponding to the hollow body can be inflated to form a bladder and the mold is closed against the inflation pressure is pinchable. In this way one is extraordinary over the other plastics processing techniques inexpensive production possible.

The front piece advantageously has the shape of a rectangular double-walled pocket, the inner pocket bottom of which the Grip groove depth determined.

In a further development of the invention, in the front wall of the hollow body there are zv / ei arched wall sections with opposing ones Arching direction provided. Di © enables basically grasping the front piece with both hands.

If the two arched wall sections form two pockets facing away from one another with their openings, as in accordance with an advantageous embodiment of the invention, it is possible to use the grip grooves formed by the two pockets
to intervene with one hand at the same time, which makes pulling out the drawer or the pull very easy.

The two wall sections are advantageously arched horizontally so that even when both hands are engaged in
the grip grooves no hand needs to be particularly twisted.

Another advantageous development of the invention is that the rear wall of the pockets with the rear wall
of the hollow body is connected. This connection is created when the molded parts are closed in the blow molding process by baking or welding the wall areas and in contact with one another
ensures that the front wall of the hollow body with the
two arched, pocket-shaped wall sections when applying greater tensile forces to open a heavy drawer
is not bulged against the rear wall of the hollow body. A further consolidation can of course also be achieved thereby
be achieved that the two wall sections forming the pocket bottoms abut one another and glued or bonded to one another.
are welded.

The front wall section located between the pockets expediently has one which is provided for receiving an identification Recess .-- This can be slightly dovetail

509847/0151

have shaped edges so that the marking is clamped, v / can earth.

A favorable appearance of the front piece results in the same rectangular shape especially when the The outer edge of each bulge is substantially rectangular.

According to an essential embodiment of the invention, the front piece consists of macroion. Makroion is a plastic from polycarbonate of 4,4'-dihydroxydiphenyl-2,2-propane. Makroion is extraordinarily scratch-resistant, against acids, oxidizing and reducing agents, i.e. against all possible agents Attacks within the scope of the intended use persistent, and therefore particularly suitable for use in drugstores and pharmacies.

The invention is explained below on the basis of the description of exemplary embodiments with reference to FIG Drawing explained in more detail.

Fig. 1 shows a front view of an inventive Front piece;

FIGS. 2 and 3 show, on an enlarged scale, sections along the lines H-II and IH-III in FIG. 1.

Figure 4 shows a front view of one with two pockets

provided front piece; 509847/0151

FIG. 5 shows a section along the line V-V in FIG. 4.

The front piece 1 shown in FIGS. 1 to 3, for example, serving as a front piece for a drawer is formed by a Makrolon hollow body, the front wall of which is depressed in the manner shown, so that a double-walled pocket results, the inner pocket bottom 2 of which corresponds to the depth of the grip groove 3 formed by the pressing certainly. In the present case, the pocket top 4 is set back in an arc shape over the entire width of the front piece, the inner pocket bottom 2 being correspondingly curved, so that an essentially constant handle groove depth is obtained.

Such a front piece is made in such a way that one blows a hollow body from macroion, around which one then a multi-part mold closes, or by placing the plastic as a bubble in a closed mold from the start blows in. The process is very simple and the shapes required here can be made up with a fraction of those Manufacture costs necessary for plastic injection molding are.

Due to the design as a hollow body, the present front piece also has extraordinary stability in the Comparison, for example, with an extruded profile with an approximately U-shaped cross section.

4 and 5, a front piece 1 'is shown, which is also formed by a Makrolon hollow body, the front wall of which forming two pockets 5 and 6 in is depressed in the manner shown. The two pockets

5 and 6 are horizontal with their openings facing away from each other are. The two rear walls 7 and 8 of the pockets 5 and

6 are firmly connected to the rear wall 9 of the front piece 1 ', what happens during the blow molding of this front piece in such a way that the moldings forming the bulges of the front wall 10 are brought up close to the molded part provided on the rear wall 9 or are brought up, so that a material connection takes place.

The lying between the pockets 5 and 6 front wall portion is provided with an indentation 11, which is a Can hold a label indicating the contents of the drawer.

The outer edge of each indentation 6 is essentially rectangular.
