Description

Soul for a strip-like structure

This invention relates to strip structures for sealing, trimming, holding, and various other purposes. In particular, it relates to souls for such strip structures, the souls have an elongated shape, preferably made of sheet metal, and basically fillet-like shape to be attached in an encompassing spread fit to a corresponding object, Z ₀ B ₀ to a handpiece or an edge flange of the object

One of the main objectives of the invention is to provide a core for tire structure with which it is easy, fast and can effectively combine a material which serves as tissue, or the like as a coating and thereby, for example, _e provides a stripe structure for trimming purposes, or which yields and buffers such as rubber or the like and thus, for example, results in a strip structure for sealing purposes «,

Another of the main goals of the invention is provision a soul for a strip-like structure, which through its constructive simplicity, its economic Production and their all-round effectiveness in performing the tasks intended for them is marked »

More specific objects of the present invention are to provide the core of a strip structure with the following properties equip.

The soul "possesses unusually high flexibility both Longitudinally as well as transversely, so that it is capable of being easily and firmly attached not only to splashing, edges and other parts that adhere to different thicknesses, but also to those parts that twist and turn or that otherwise "show considerable and manifold straight-line deviation".

The core is formed from elements that are basically arranged in a zigzag and the edge parts of which overlap, preferably also touch and provided with at least one "projection" on each pair of such overlapping edge parts which is best shaped like a claw or point for attaching the soul.

The projections for attaching the core are correspondingly hardened, e.g. by chrome plating, in order to do their job better loosening up when pinning the soul and also giving the opportunity to the other parts of the soul if necessary made from cheaper metal.

These protrusions are designed and arranged to provide effective cohesion for the overlapping Edge parts of the zigzag-arranged elements that form the soul result in a reinforcement of the soul bring themselves without, however, impairing their desired flexibility.

BATH ORIGINAL 809803/03 12

Each pair of overlapping edge parts of the zigzagging elements forming the soul is through two projections adhering to the soul held together, which are each pair in aligned contact with one another to to reinforce it into a strong and rigid unit.

FIGS. 29 and 30 are views which basically correspond to FIGS. 2 and 3 and show a "soul" which differs from the first example of the invention shown there only in that the elements forming the soul are separate members which are suitable for formation held together in the soul.

As will appear in more detail below, can the souls according to the invention with a suitable covering material such as fabric or the like are united to thereby, for example, a strip structure for trimming or for other purposes where a soul cover is necessary or desired? the souls can with suitable, Resilient or resilient material such as rubber or the like are combined to thereby, for example, a strip structure for sealing purposes to yield j or the souls can with material both for covering and for sealing depending on the Type of strip structure used with them to be combined »

In short, the inventive souls are elongated Shape, U-shaped in cross-section and contain inner and outer layers of structural elements, which are basically in the Are arranged in a zigzag; the hand parts of neighboring elements overlap and each form a pair? that with at least a protrusion adhering to the core is provided. The core protrusions preferably have the shape of a point or Claw and are so constructed and arranged that they the effectively hold together overlapping edge parts of adjacent structural elements »

So the soul has a relatively robust shape and

but unusual, high flexibility both lengthways and auoh OLuer, so that it is easy and tight in an encircling spread seat at an edge part of an object independently τοη changes in its thickness or deviations from the straight line Line can be pinned.

In the inventive model illustrated in FIGS. 1 to 7 the core consists of a relatively narrow band of sheet metal, preferably steel, that way is bent or processed in some other way so that the soul emerges from upper and lower layers of elements leaves, which are basically arranged in a zigzag; while the edge parts 10 of adjacent upper and overlap lower elements, as best seen in Figure 1.

In this view and also in Figure 2, the core formed by the zigzag elements is in a flat state, whereby the elements 11 of the lower layer and the elements of the upper layer touch each other. "However, the soul has in its final shape, as can be seen in Figure 3, U-shaped cross-section for an enclosing expansion seat on an edge part or edge flange of the object on which it is used «

For such attachment to such parts 13 and Figures 6 and 7, there is each pair of the overlapping edge parts 10 of the core elements 11, 12 are provided with at least one attachment projection, which is preferably pointed, claws or Has a barbed shape, as shown here, in order to better hold itself when engaging in the object used with it.

bite, of course you can have such protrusions of the soul manufacture in different ways; here they were made economical and easy by pressing or punching out of the Elements of the soul self-made

If required, these protrusions can perform a single tacking function, namely (a) tacking the soul on the corresponding commodity, or (b) attaching a suitable layer to cover it and / or sealing the core, or (c) both types of attachment so However, it is best to design and arrange the projections on the core in such a way that they provide the additional and take on quite an important function, the overlapping. To solidify edge parts of the soul elements in itself.

To accomplish this consolidation, the projections from the elements of one layer are allowed to pass through appropriately aligned holes in the elements of the other layer. If the projections are to go into the groove 15 of the core, as in this first sample of the invention (FIGS. 1 to 7), the projections can be printed from the edge parts of the elements 11 of the outer element layer (the lower layer in FIGS. 1 and 2) or punched and inserted through correspondingly aligned holes in the adjacent edge parts of the elements 12 of the inner element layer (the upper layer in Figures 1 and 2) In FIGS. 16 and 16, the invention pattern illustrated, the projections

8 0 9 8 C 3/0 3 1 2

from the edge parts of the elements 12 of the inner element layer pressed or punched and through aligned holes in the "adjacent Eandteile of the elements 11 of the outer Element layer can be plugged outwards.

Preferably, however, as shown in this first inventive pattern, each edge portion of each of these is overlapping Pairs 10 of the elements 11, 12 are each provided with a projection; the "two projections of a couple created in this way butt against each other in alignment with the result of doubled protrusions, which in themselves are extraordinarily solid and coarse Represent the whole.

In this respect, the soul protrusions in this first inventive pattern go inwardly into the groove 15, the projections 16 of the edge parts of the elements 11 of the outer layer inward through aligned holes 17 in the edge portions of the elements 12 of the inner layer; included As can easily be seen, the holes 17 arise from the nature of the production of the inwardly pointing projections 18 of the edge parts of the elements 12 of the inner layer. Ba the protrusions 16 and 18 of each butting pair of protrusions have approximately the same size and shape, the projections 16 fit in the edge parts of the outer elements 11 in the tight fit or An interference fit in the holes 17 of the edge portions of the inner members 12 with the result that within each pair of overlapping Edge parts 10 a firm and effective cohesion is created. However, since these tightly overlapping edge parts the free longitudinal edges of the side walls 19 and 20 of the Seeleh-

809803/0312

profile, its desired flexibility is neither longitudinally still transversely impaired.

Figures 4 and 5 show how easy the U-shaped Soul of Figure 3 can be bent; either convex. like in FIG. 4, the overlapping end portions 10 of the elements moving apart at a distance or angle, or concave as in FIG FIG. 5 »wherein the overlapping edge parts 10 of the elements move together at a distance or angle; Figures 6 and show how the soul looks at the edge parts or edges 13 »14 can be easily adjusted, which varies in strength change and / or twist and turn and / or have other, manifold and approximately straight deviations «)

It is therefore out of the peculiar G-efüge of the core (of the zigzag position of the elements, etc _o) visible and indicated in Figures 4 to 7 that the present soul both longitudinally and transversely shows unusually high flexibility and yet as a result of the effective cohesion of the overlapping edge parts 10 of adjacent elements has the required strength and coarseness.

Although the souls according to the invention can be made from any suitable sheet metal, it is particularly satisfactory a steel with a relatively high carbon content, as it gives the core protrusions a hardness that is desired at all times and at times it is quite necessary "if the soul protrusions are made sufficiently hard in another way" a steel with a low carbon content and therefore a lower cost can be used.

809803/03 12

A suitable way on which the soul protrusions are sufficient can be hardened is by cladding or plating them with a metal such as chromium; such a FIG. 8 shows the invention sample. In this view, 21 denotes the chrome plating for the core projections 22, 25, projections which, like the rest of the soul, come from one proportionately cheap low carbon steel can be made. The chrome plating can of course can be performed in any manner.

As mentioned before, the inventive souls can are coated accordingly in order to create a strip-like structure Stocking or to supply for other purposes, if required, and / or the souls can with appropriate, compliant or resilient material such as rubber can be provided to provide a strip structure for a tight seal.

A sealing, strip-like structure is illustrated in FIG. 9, which is formed by the core of FIGS Makes use of; you can see there that the core designated with the collective number 24 is from the U-shaped part 25 of a rubber seal is tightly enclosed, the sealing wing 26 from the upper edge of one of the side walls of the U-shaped part 25 to the side protruding? The rubber seal is best an injection-molded one Profile, the U-shaped part 25 is provided here on the upper edges of its side walls with flanges 27, which according to is turned down into the hollow groove around the upper edges of the inner side walls, around the rubber seal on the To attach soul. It will be noted that the rubber flanges 27 remove the upper edges of the inner side walls from the flanges 28,

In the core of FIGS. 1 to 7 and 9, the projections of the core protrude into its groove, while in FIGS. 16 and 17 to be described later, the other way round protrudes out of it. However, there may be times when you want some projections to protrude and others to protrude. Such a core can be seen in the figure, in which the projections point alternately inwards and outwards, those pointing inwards are designated with 32 and those pointing outwards with 33. The inward projections, as discussed in the earlier inventions, can be used to attach the core to the edge portion or edge flange of an article as in Figures 6, 7 and 9, while the outward projections can be used for various purposes , Z ₀ B ₀ for attaching a coating of sealing material to the core or for inserting it into a groove or the like for trimming or for combined purposes

In the previously described cores of Figures 1 to, the projections are pressed out or punched transversely to the core and point downwards at their base point both inwards (FIGS. 1 to 9) and inwards and outwards (FIG. 10). If desired, however, the projections can also be pressed or punched lengthways to the core and then to its side walls

Ea is easy to understand that the soul of the characters 11, 12 and 13 in approximately the same way as that shown as the first inventive sample in FIGS. 1 ″ to 7 Soul fulfills its task.

In FIG. 14, the core projections 40 are pressed or punched transversely out of the elements 41, 42 as in the figures 1. "to 10. However, one notices that the pointed ends of the Soul projections 40 of FIG. 14 apart, if the soul assumes its preliminary, flat form as in Figure 14, and point inward upwards when the soul its final Assumes U shape (not shown). Because of their equality in all other parts with the soul of Figures 1 to 7, a further explanation of the core of FIG. 14 is not considered necessary.

In the invention pattern illustrated in Figure 15, the outer edges 44 of the overlapping edge parts of the core, in other words, the free longitudinal edges of the inner side walls are bent outwards pointing away from one another. Also is the core is provided with a suitable covering 45 made of fabric or the like, which does not only go around it on the outside, but also extends into its groove, where it is held by means of the projections 46 passing through it will. This pattern of the invention does not need to be explained further.

In the inventive pattern illustrated in FIGS. 16 and 17 ″, the foot part 48 of the core is essentially flat, with its side walls 49 »50 being displaced inwardly away from the side edges of the foot part. As can be seen in FIG Soul of this pattern are arranged so that it is inserted with its "foot part 48 facing outwards in the groove 51 of an object 52 in order to force the edge parts of a coating 53 for this object there _o

to which the soul is to be attached. However, their projections can also be shaped differently, as can be seen in FIGS. 19, 20 and 21, which basically correspond to FIGS. 1, 2 and 5 and 11, 12 and 13.

In the example of the invention illustrated in FIGS. 19, 20 and 21, the projections 60, which are pressed or punched out of the elements 61, 62, have a hollow, basically truncated cone-like shape and point into the groove of the core when it is in its final U-shape as in Figure 21 assumes. As the figures 20 and 21 show, the overlapping edge portions hold the members 61, 62 through the core projections together, and its engagement with the edge portion or the edge flange of an article ranges, although they are not pointed, generally composed of, in order to maintain the adherence ·

In the invention pattern of Figures 22, 23 and 24, the basically the figures 1, 2 and 3, 11, 12 and 13 and 19, 20 and 21, the core protrusions 64 are not zigzagged by pressing or punching the metal Elements 65 and 66, but by lateral bending of the outer edge parts of the overlapping edge parts of these elements, in this case by turning them at right angles. As you can see here, they show Core projections inward into the groove of the core when this assumes its final U-shape as in FIG. 24; But of course they can either all point outwards or some inwards and others outwards Fig. 22 gathers, the elements of the soul are referring to

. In the invention illustrated in FIGS. 25 and 26 If it is, the zigzagging elements 69/70 have an enlarged width so that they not just a U-shaped part 71 for the soul attachment as with the earlier inventions, but also one Side extension 72 has to a Abdient- or buffer piece 73 made of rubber or other flexible or resilient material to record.

For the purpose of attaching and also to hold together the overlapping parts of the elements 69, 70, which form the core, which lie on the upper edges of the side walls of the U-shaped core part 71 are claw-shaped or barb-shaped Projections 74 are printed or stamped on the elements, as in the inventive samples illustrated in FIGS sees, pressed or stamped from those overlapping edge portions 76 of the elements which form part of the side extension 72 form, and these projections 75 not only have to hold together the overlapping edge parts 76, but also, as FIG. 26 shows, for holding the sealing or buffer piece 73 on the side extension to care.

The overlapping edge parts 78 become the present invention of the elements 79 »80 forming the core by claw-shaped or barb-shaped projections 81 that adhere the core held together, as in a number of the inventions described above. However, this pattern is where the others lie Parts of the elements 79 »80 spaced apart over a greater distance and only one against the other over a smaller distance.

In the last example of the invention illustrated here in FIGS. 29 and 30, the elements that form the soul are 82, 83 separate pieces of metal and not parts of a continuous, long metal band as in those previously described Invention Patterns.

Although these elements 82, 83 of the pattern of FIGS. 29 and if necessary, they can be held together by additional means for the formation of the soul, they are that alone here by the projections 84 adhering to the core, which the overlapping edge parts of the elements reliably as in the previous to hold together the described invention patterns »

From the foregoing description of a number of inventive patterns it becomes quite clear that souls are separated by zigzagging elements with overlapping, by soul-clinging elements Projections formed by the edge portions held together have many important advantages, including here only a few have been explained.
