DE2358997A1 - Folding bookcase with normally rigid structure - can be folded to occupy only half its volume for transport - Google Patents

Abstract

The bookcase has a single piece back with top two sides, five shelves and a bottom cupboard door. The top has a horizontal hinge so that the part can be swung downwards. Similarly a part of each shelf can be swung upwards. The sides have vertical hinges to allow them to be swung inwards. The cupboard door is hinged to a shelf which is also hinged and can be swung upwards. The volume of the bookcase can thus be reduced by half for convenience of transport. The shelf portions swinging upwards are provided with pins which engage in eyes in the sides to hold the structure rigid when in normal use.

"Collapsible Shelf"

The invention relates to a collapsible shelf with section heights that can be folded around vertical axes.

In a known shelf of this type (DT-AS 1 429 600) 'the side panels of the shelf are continuous, the back wall is divided into several, placed one next to the other like an accordion Divided into areas. To collapse, the furniture body is folded up like a harmonica. This known construction can be very space-saving fold up or fold up, their main disadvantage, however, is their many parts and its numerous joint parts that impair the strength of the body.

The invention is based on this prior art The underlying task is to create a shelf that is as stiff as possible in itself despite its collapsibility should be designed that is simple and inexpensive too finished is easy to set up and use in a variety of ways

This object is achieved according to the invention in that a shelf of the type mentioned has a rigid body -has, the side walls of which can be folded around vertical axes. Have Vqrderteile, also to be firmly arranged in the body Soils or the like. The front areas in the direction of the The back panel of the carcass can be folded around horizontal axes, with the top and bottom panels also folding around horizontal axes have front areas.

It has proven to be useful that the depth of the fixed areas of the floors is smaller than the depth of the fixed Areas of the side walls. This makes it possible to send all of the individual shelves towards the Fold down the rear wall and fold the inwardly foldable areas of the side walls onto the front.

To achieve a particularly stable, inherently rigid shelf The invention also proposes that the foldable front areas of the floors and side walls can be locked to one another are.

The solution according to the invention has the advantage that it is a rigid one Has a basic structure that gives the shelf the necessary rigidity and stability when it is set up. Furthermore is due to the foldability of the floors and side walls "in their front sub-areas a reduction in the Shipping volume when folded by at least 50% compared to the volume when the shelf is set up achievable. When delivered in several attachments, like them is quite common, is with the construction according to the invention not only to keep the height of the individual elements small, but also their overall depth. The assembly of the invention Construction is extremely simple. To set it up, the folded shelf is put upright, the front side panels are folded out, then the top panel is folded up and then all of the foldable ones can automatically be opened front floor areas fall one after the other into their final position. - - - 3 -

The unfolded front areas-the floors are in their final position held in Faehbodenentragern, which are designed, for example, as a snap. In a preferred embodiment, the front areas of the floors on their underside each pin, which in attached to the front areas of the side cheeks eyelets-Od the like. insertable are. Such a lock is extremely simple and absolute stable and reliable.

The invention also proposes that the front area of the Top bottom can be folded down, while the front Area of the sub-floor "is hinged to the top so that it can be folded up.

It has been found to be useful that the sub-floor has a further, about a horizontal axis upwardly foldable area, which has a front flap for the lower compartment formed of the shelf.

The fixed areas of the shelf can, instead of being unsolvable to be connected to the fixed area of the body, can also be changed in their height adjustment. To this Purpose can be done in a known manner in the side walls of the fixed body part perforated strips with shelf supports are provided. In this case, the corresponding in different heights arranged locking elements for the foldable areas of the floors are provided in the foldable areas of the side walls.

The following is a preferred embodiment of the invention described in detail using the drawing ». Show it:

3 shows a section along III - III according to FIG. 2,

4 shows the detail IV according to FIG. 2 on a larger scale,

Fig. 5 is a partially sectioned view of the

Pin-and-eye connection between the foldable area of a floor and the foldable area a side cheek,

FIG. 6 shows a section along VI - VI in FIG. 5.

The fixed area of the furniture body is made up of a rigid rear wall 1, a fixed area 2a of the top floor, a fixed one Area 3a of the underbody, a fixed area 4a of the left side cheek and a fixed area 5a of the right side cheek educated. The parts mentioned are inextricably linked. They form a rigid and rigid basic structure for the shelf. The floors are each down about horizontal axes or pivotable at the top. So the front area 2b is around one horizontal axis can be folded down, the front areas 6b of the floors 6 can be folded upwards about horizontal axes on the hinged rear fixed areas 6a foldable. The front area 4b of the side cheek 4 is about a vertical axis hinged inwardly foldable to the rear fixed area 4a. The front area 5b is analogous to the rear area 5a the side wall 5 is articulated. The foldable parts are linked to one another with the help of a so-called "piano hinge".

In addition to its front area 3b which can be folded upwards, the sub-floor 3a has a further foldable area 3c, which is hinged to the front edge of the area 3b. From Fig. 1 and 2 it can be seen that the area 3c is a cover flap for the forms the lowest compartment 7 of the shelf.

At the top, the compartment 7 is closed off by the bottom ^ ¹ . The foldable areas 6b of the floors 6 have downwardly opposite side edges on their side walls 4 and 5

pointing pin 8. On the foldable areas 5b and 4b of the Side cheeks are firmly screwed on eyelets 9, into which ' the pegs 8 engage in a locking manner when the shelf is set up. A lamp 10, known per se, is also provided on the top floor 2. The lamp 10 is forwarded by a billboard

11, which is simply inserted from above into corresponding vertical slots after the shelf has been set up.

The shelving can be set up without any assembly tools take place. In Figures 2, 3 and 4 it is the collapsed position of the various foldable elements indicated by dash-dotted lines. To set it up, the foldable side panel areas are pivoted by a little more than 90 ° in relation to the folding position, so that the front area · 2b of the topsoil past the eyelets be pivoted above and with its pin 8 from above into the ent speaking eyelets 9 can intervene. When the pins 8 are in the eyelets 9, the fixed side cheek areas are with them the foldable side wall areas in one level. Afterward the foldable areas 6b of the floor can all fold into their locking position. The ready-to-use installation of the Regals can be done in the shortest possible time.
