Abstract
A method and tool for forming convexities (3, 4) in a plate body (1), which plate body (1) comprises a main face (2) and a plurality is of side edges The plate body (1) is inserted between two tool halves (11, 12), which are brought together and interact to press a first set of convexities (3) in a first direction relative to the main face (2) of the plate body (1) and a second set of convexities (4) in a second, opposite direction relative to the main face (2) of the plate body (1). The convexities (3, 4) are formed along a straight line across the plate body (1) between two of the side edges thereof. The plate body (1) is secured so that the main face (2) thereof maintains its orientation, and each of the convexities (3) in the first set of convexities is pressed out by a length (1) measured from one side of the convexities (3) at a point (20) on the main face (1) of the plate body (1) along the convexity (3) to the second side of the convexity (3) at a point (21) on the main face (2) of the plate body (1), which is substantially equal to the corresponding length (1) by which each of the convexities (4) in the second set of convexities is pressed out.
Description
- The present invention relates to a method in accordance with the preamble in
independent claim 1 below, a tool in accordance with the preamble inindependent claim 3, and a plate in accordance with the preamble inindependent claim 6. - A method, a tool and a plate in accordance with the above are known from U.S. Pat. No. 5,318,176. This publication teaches a rail that is produced by placing a plate-shaped body in a tool, which forms convexities in two opposite directions relative to the main face of the plate body. However, at the same time as the convexities are formed, the plate is also bent so that it becomes essentially U-shaped in cross-section. Owing to the substantial bending of the plate, only rail-shaped bodies having just one row of convexities can be made by means of this method and tool. A plate of greater extent and having several rows of convexities cannot be produced using the taught method and tool.
- U.S. Pat. No. 3,851,846 teaches a plate-shaped body where convexities are formed in opposite directions. However, these convexities are only made at one side edge of the plate, which results in tension arising in the juncture between the innermost convexity and the distal planar portion of the plate. It is therefore not possible to produce such convexities over a major area of the plate, since these convexities will result in the plate twisting markedly. Also, the plate is only intended to receive an adjustable leg of a dishwasher. U.S. Pat. No. 3,062,570, U.S. Pat. No. 3,208,505 and U.S. Pat. No. 4,711,420 teach other variants of plates equipped with convexities. All the plates are produced with specific uses in view, such as a comer connector for a stand, a holder for a burner and a post for use in a shopfitting system. None of these publications teach convexities which are suitable for arranging over a major extent of a plate.
- The main objective of the present invention is to make possible the provision of convexities over a larger area of a plate than is possible with the known methods and tools. A plate of this kind having convexities over a major area of the plate, for example, across the entire plate, may, for instance, be used as a suspension plate, for use, for example, in a shopfitting system; as a substructure for a floor, wherein the plate has convexities ensuring a suitable distance between, for example, a wooden floor and a concrete floor, and may also be made of a somewhat yielding material so that it springs a little under pressure; as a sound-absorbing wall in that, for example, two such plates can be arranged with insulation therebetween, where the purpose of the convexities is to scatter the reflected sound; as a lamp shade, wherein a light source is mounted on the back of the plate and the plate serves to disperse the light so as to provide indirect illumination from, for example, a wall or a ceiling; as anchoring for, for instance, reinforcement bars, in that the plate can form a connection between several reinforcing rods and hold them correctly spaced apart; as decorative plates on walls or ceilings, optionally also for decorative purposes on other articles, e.g., lamp shades; and as a hinge connection, the convexities formed along the respective side edges of two plates being intermeshed and a hinge pin fed through the convexities.
- The aforementioned are merely examples of the use of a plate produced according to the method of the invention and using the tool of the invention. More possible uses will almost certainly come to light as the invention begins to be used.
- The above-mentioned possibilities are achieved by means of the features disclosed in the characterising clauses in the said independent claims hereinbelow.
- The dependent claims disclose advantageous embodiments of the invention.
- The invention will now be explained in more detail with reference to the accompanying drawings, wherein:
- FIGS. 1a, b, and c show a tool according to the present invention in three different stages of the production of a plate according to the invention, using the method of the invention;
- FIG. 2 is a fragmentary lateral view of a tool according to the invention;
- FIGS. 3a, b and c are sectional views of different possible embodiments of a plate according to the invention;
- FIG. 4 is a fragmentary plan view of a plate according to the invention;
- FIG. 5 is a sectional view of the plate of FIG. 4; and
- FIG. 6 is a lateral view of the plate of FIG. 4, used as a suspension plate.
- FIG. 1a illustrates a
tool 10, consisting of afirst tool half 11 and asecond tool half 12. On each side of eachtool half plate 1. The ejectors are each pre-tensioned pairwise against one another by means of aspring 14. - Each
tool half projections 15, which are best illustrated in FIG. 2.Spaces 16 are formed between the projections. Thetool halves projections 15 on thetool half 11 fit into thespaces 16 on thetool half 12, and vice versa. Aplate 1 is inserted between thetool halves main surface 2 and a number of side edges. - In Figure 1b the two
tool halves ejectors 13 here are pressed right in against theirsprings 14, so that they come to rest against atool holder 17. The movement of the tool halves 11, 12 towards each other then comes to a standstill. The opposing faces 18 of theejectors 13 rest against theplate 1, and theplate 1 and thefaces 18 of theejectors 13 define the dividingplane 19 of the tool. Theprojections 15 of thefirst tool half 11 project beyond the dividingplane 19 by alength 1, measured from the dividingplane 19 of the tool at apoint 20 along theprojection 15, across the top of the projection, to the dividingplane 19 of the tool at apoint 21 on the opposite side of theprojection 15. Theprojections 15 of thesecond tool half 12 also project beyond the dividingplane 19 of the tool by thesame length 1, but in the opposite direction. Therefore, an equally large amount of plate material, measured in the figured plane of Fig. lb, is pressed out to each side of the dividingplane 19 of the tool, thereby ensuring that the plate is substantially free from tension, even after the convexities have been formed. In FIG. 1c thetool halves convexities - The shape of the
convexities convexities - The row of convexities must extend from one side edge of the plate in a straight line to the other side edge of the plate. When the convexities are formed in this way a tension-free plate is obtained which maintains its original principal shape. The plate will twist or bend to a very small degree, apart from the actual convexities, and the plate will be easy to bend into a desired shape once the convexities have been formed. Before, after, or at the same time as the pressed-out portions are formed, recesses may optionally also be punched out in the plate. The recesses may be located between the convexities in one line, or they may be located between the convexities in two adjacent lines.
- In FIGS. 4, 5 and6, a
plate 1 is shown which in general comprises a first side face 2 a and a second side face 2 b. From thisplate 1,areas 3 are pressed out in a first direction, so that theareas 3 form a curved face at a distance from the first side face 2 a.Other areas 4 are pressed out from theplate 1 in an opposite direction and form a second curved face at a distance from the second side face 2 b, so that theareas row 5 across the plate. A plurality ofsuch rows 5 can be arranged at a distance from each other, and defineareas 6 between each other, whichareas 6 are in the planarmain portion 2 of the plate. Between each of theareas openings 7 are formed for the insertion of, for example, a hook 8 (see FIG. 6), bolts, thread, wires, cables, pipes and so forth. - The alternating
areas areas 3 a have a longer length than theareas 3 b, and likewise theareas 4 a have a longer length than theareas 4 b. When theinner end 9 of thehook 8 is to be fixed in theplate 1, theend 9 is inserted towards, for example, anarea 4 a, and then passed down through theopening 7 behind anarea 3 b until theend 9 reaches anarea 4 b. Theend 9 of thehook 8 is then retained between theareas - The pressed-out
areas plate 1. - FIG. 6 shows a section of the
plate 1 where the alternatingareas - A
short area 3 b, ashort area 4 b, along area 3 a, ashort area 4 b, ashort area 3 b and along area 4 a. Naturally, other patterns of alternating areas are also possible, depending upon what is to be secured to the plate. - Although in the exemplary embodiment, a plate is shown that is primarily intended as a suspension means for hooks or the like, this plate can be used in virtually any situation where it is desirable to hold together various elements. One example may be the fastening together of reinforcing rods for reinforcing, for instance, concrete. A plate may then, for example, be bent into a cylinder and held in this position by means of bars disposed substantially diametrically on the inside of the cylinder and secured in the
openings 7, in the same way as thehooks 8. On the outside reinforcing rods can be inserted through theopenings 7 along therows 5. Several cylinders of this kind can be arranged along the reinforcing rods. In this way good reinforcement will be obtained for making, e.g., pillars or columns. - As mentioned in the introduction, other applications of the plate of the invention are also conceivable, and the invention is therefore not limited to only the said areas of application, but can be used in any area whatsoever where it is desirable to have a tension-free plate provided with pressed-out portions in opposite directions.
