Abstract
The invention relates to a folding seat (1) with back support (2) which can be made by folding and gluing operations of different parts composed of a sheet of cardboard (3).
Description
- The present invention relates to a seat with back support. More specifically, the invention relates to a seat stamped out of a sheet of cardboard consisting of parts which are folded along fold lines and glued so as to produce a folding seat with back support. The invention is intended for use at festivals and the like.
- Participating in festivals requires a great deal of standing and sitting on the ground. This may result in both the back and legs becoming tired. In order to rest the back, it is an advantage to have a seat device with back support.
- Seat devices intended for festivals can be found in the form of deckchairs and other folding chairs. Storing these chairs requires a relatively large space, and even though the weight per chair is not necessarily so very great, a large number of chairs will represent a considerable weight.
- There is a need for a type of seat device which is light and easy to move, and where a substantial number can be stored in as small a space as possible. The seat device, moreover, should be easy and inexpensive to produce.
- U.S. Pat. No. 4,385,782 describes how a seat can be made from cardboard. This seat has several drawbacks, one of which is that it is relatively flimsy and therefore unable to stand the strain when one leans against the back support for a long period. Furthermore the user is required to perform several folding and fastening operations in order to arrange the seat as it is intended to be used.
- U.S. Pat. No. 5,020,854 describes a seat which has a back support that will stand more weight, and will be better suited for leaning against than the seat described in the previous paragraph. Nevertheless it is not particularly suitable for use at arrangements where a great many people are gathered, since the part that holds up the back support is exposed to blows or kicks which may cause the back support to give way.
- The present invention solves the above-mentioned problems, and describes a folding seat device in the form of a seat with a solid back support.
- During production of a seat according to the present invention, a stamped-out piece of cardboard is folded along fold lines and glue is applied to some parts in order to form a seat with a back support. After this, the chair is folded up so that it becomes completely flat and thereby suitable for stacking, storage and transport.
- Transportation, storage and handling of such seats will be a matter of simply bundling stacks of cardboard sheets together.
- Thus when the seat has to be put to use, only one simple operation is required to set it up.
- The present invention describes a seat with back support which is made of a sheet of cardboard stamped out in one piece which is folded along fold lines and glued so that the seat is formed by means of folding and gluing operations.
- The inventive feature of the seat is that it can be converted from a folded to an unfolded state by means of one folding operation. This is made possible by side members which have a fold line that causes the side members to be folded in between a back support and a rear panel, and moreover that a part of an underside located between the back support and the rear panel has a fold line that causes it to be unfolded from the two last-mentioned parts when the seat is folded up.
- The seat has a high reuse value and is particularly well suited for use at concerts and festivals held outdoors.
- The invention also describes how to fold and glue different parts of a sheet of cardboard in order to provide a seat according to the invention.
- The inventive features are further described in the independent claims in the following set of claims. More detailed features are indicated in the dependent claims.
- The invention will now be described in greater detail with reference to the figures, in which:
-
FIG. 1 illustrates an example of a stamped-out cardboard sheet with a shape which forms the basis for making the seat according to the invention; -
FIG. 2 illustrates the unfolded seat viewed partly from behind; -
FIG. 3 illustrates the folded seat viewed from the side, and -
FIG. 4 illustrates details in a folded seat. -
FIG. 1 illustrates an example of a basis for making aseat 1. Here we see the shape of a blank stamped out of a sheet ofcardboard 3, where the different parts are defined by dividing lines that facilitate folding and gluing the parts in order to turn thecardboard sheet 3 into aseat 1 according to the invention. The letters indicate fold lines which are described in more detail below. - As already mentioned, the
seat 1 withback support 2 is made of a sheet ofcardboard 3 stamped out in one piece which is folded along fold lines, thereby forming theseat 1 by means of folding and gluing operations. Thecardboard sheet 3 comprises a plurality of parts which are interconnected at the fold lines, and where the parts comprise asitting surface 8, aback support 2, twoside members rear panel 9 and anunderside 6. - In a preferred embodiment the
seat 1 can be converted from a folded to an unfolded state by one folding operation which is made possible by theside members side members back support 2 and therear plate 9, and moreover the part of theunderside 6 located between theback support 2 and therear panel 9 has a fold line that causes it to be unfolded from the two last-mentioned parts when theseat 1 is folded up.Small grooves cardboard sheet 3 in order to ease the load at a stress point. Thegrooves sitting surface 8 and theback support 2. - The cardboard sheet is further provided with a
handle 10 and aflap 11 for inserting in agroove 12 which will be described in greater detail below. - In
FIG. 1 , as already mentioned, the letters A to D indicate fold lines, and each letter describes how the different surfaces bordering on the fold lines should be folded in order to assemble a seat according to the invention, and in order to open or fold up the seat. - The letters A and B indicate folding operations required to make the seat by means of folding and gluing operations. A indicates that the surfaces bordering on this fold line are folded up from the paper plane, and B indicates that the surfaces bordering on this fold line are folded down in the paper plane.
- One of the
side members 5 has a fold line that forms afirst locking part 4 which is glued to the lateral edge of therear panel 9. The bottom part of the sittingsurface 8 has alower part 13, with asecond locking part 14, both of which are glued to the underside of thesitting surface 8. Thegroove 12 is stamped out and forms a part of the locking mechanism when the seat is folded up. Thelocking part 14 is preferably glued to the underside of the sittingsurface 8, close against and flush with the edge of theunderside 6 which is also glued to the underside of the sittingsurface 8. -
FIG. 2 illustrates the seat that results when the folding operations A and B as well as the gluing described above have been completed. The seat is then operative in the sense that it can be used to sit on. - In order to increase the stability and rigidity of the
seat 1, in a preferred embodiment parts of theunderside 6 are glued to the underside of thesitting surface 8. - In order to produce a
folding seat 1 withback support 2 by means of a sheet ofcardboard 3 stamped out in one piece with parts and fold lines as described above, the parts are folded along the fold lines A and B so that theside members back support 2 and therear panel 9. Furthermore afirst locking part 4 in oneside member 5 is glued to the lateral edge of therear panel 9, thereby forming a cavity between theback support 2, therear panel 9 and theside members underside 6 is at around 60° to therear panel 9 and theback support 2, thereby closing the said cavity. Finally, alower part 13, which is at 180° to the sittingsurface 8, is glued with asecond locking part 14 to theunderside 6. - The letters C and D in
FIGS. 1 and 2 indicate folding operations required for opening and folding up the operative seat. C indicates that the surfaces bordering on this fold line are folded up from the paper plane, and D indicates that the surfaces bordering on this fold line are folded down in the paper plane. - When the
back support 2 and therear panel 9 are pressed against each other, the side walls are folded in between theback support 2 and therear panel 9. Furthermore, the part of theunderside 6 located between theback support 2 and therear panel 9 is folded out from the last-mentioned surfaces. The next operation is to pivot the sittingsurface 8 down and round therear panel 9 in the direction of the arrow and round the axis of the fold line indicated by the broken line inFIG. 2 . This operation will cause the part of theunderside 6 located between theback support 2 and therear panel 9 to be folded in the same direction, with the result that it will be located between therear panel 9 and the underside 6 (which is glued to the underside of the sitting surface 8) when the two last-mentioned parts are pressed closely together. -
FIG. 3 illustrates theseat 1 in a folded state with parts of theunderside 6 located between therear panel 9 and theunderside 6 which is glued to the underside of the sittingsurface 8. In the figure there is also illustrated aprotuberance 15 marking the edge of thegroove 12 shown inFIG. 1 . Thehandle 10 for carrying the folded seat is also shown. -
FIG. 4 illustrates details of the folded seat, and how the folded position is secured by theseat 1 being provided with aflap 11 in the upper part of theback support 2 and agroove 12 in the lower end of the sittingsurface 8 for receiving theflap 11, thereby fastening them to each other. - Even though a specific and preferred embodiment is described in this description, it will be obvious how other designs can be attained without deviating from the concept and scope of the present invention.
