Description

Handle, in particular for holding loops in vehicles

FIELD OF THE INVENTION

The invention relates to a handle, in particular retaining loop in vehicles, with a bent in the form of eight belts of flexible material with a ner loop for holding and a loop for fastening and a multi-part socket for holding the loops relative to each other.

BACKGROUND OF THE INVENTION

Such handles have long been known. A handle made of a one-piece belt is described in DE 78 24 276 U1, in which two individual cantilevers per loop position and the cantilever each are provided with correspondingly positioned and dimensioned perforations of the belt for three connection regions of the one-piece belt held in the lampholder. Here, for two belt sections, the trunnions on opposite inner sides of a arranged rectangular mounting ring, while the two Kragzapfen for the third belt portion are arranged on an independent, insertable into the socket member such that the third pair of pins between the two ringinnenseiti- ZEN pin pairs comes to rest. The threading of the male part in the mounting ring requires a considerable skill, especially since this insertion can only take place when two belt sections are already introduced into the associated pins of the mounting ring. In order to ensure sufficiently large holding forces all components of the two-part version would have to be made of relatively high-quality material and / or with very large dimensions.

Moreover, it is known to use generic handles as advertising material. For this purpose, DE 203 09 342 IM proposes to produce the retaining loop part of such a handle from two transparent PVC parts welded together and to insert a suitably dimensioned, ready-made, individually printed advertising carrier made of a strong carrier material between the two PVC parts.

SUMMARY OF THE INVENTION

On this basis, the invention is based on the problem to provide a handle, which ensures high holding forces with low material costs. Desirable is also a quick interchangeability or installation of the handles by not or only a few trained personnel, without compromising safety. Another object of the invention is the provision of a concept of advertising serving as an advertising medium, which ensures the required security despite low production costs.

To solve this problem, a handle with the features of claim 1 is proposed. The invention is therefore based on the basic idea, in the interior of a holder clamping the clamping together the belt holes penetrating fasteners in a block-like structure. This optimizes the transmission of force between the belt and the socket in the area of the perforation with minimal belt weakening. Claw means according to claim 7 act independently on the belt in the sense of a power transmission. This is possible without unduly weakening the tensile strength of the belt, especially if this is done by claw means acting laterally from longitudinal reinforcing fibers or fiber strands within the belt. Such clawing agents are of inherently inventive importance. In a combination of block-like Haltemittelausbildung in the punching area and acting on the belt surface Krallmitteln, the forces between the socket and the belt are transmitted in such a way that both the belt and the socket even with extreme shock loads, such as occur in rear-end collisions of a means of transport can withstand the stresses. This while using the straps from novel materials in this area, which allows a multifunctionality of the belt, for example, as an advertising medium at a reasonable cost.

In order to improve the pull-out strength of the handle, its loops and / or the socket for extreme loads, it is proposed to form double-layered loops for attachment to a carrier (second). For this purpose, the two end regions of the belt are preferably superimposed on one another in order to achieve the double layer in the region of the (second) loop which is used for attachment to the carrier. To fasten both loop layers, the belt 4 on both sides of the (second) loop forming end portions provided perforations of the belt, which are held together by the multi-part frame and in particular interspersed with a holding block. Handles with a two-ply second loop for attachment to a support are - independently of the feature of claim 1 - of independent inventive importance. It is especially advantageous if the inner end region of the belt forming the second loop is shorter than the outer one. ing end area is, so that the two end portions in use over their entire length abut each other. As a result, particularly high frictional forces are transmitted in the load case, which relieve the connection point on the socket.

Advantageous embodiments of the invention, which in themselves are of independent inventive significance, are evident from claims 2 to 38.

The width of the straps is comparatively large and is preferably between about 30 mm and 50 mm, preferably about 40 mm. As a result, it is not only possible to transfer low retaining forces at low cost, but also to allow this belt to slightly deform the belt cross section between the two side edges, so that the side surfaces of the belt curve concavely or convexly and thus adapt to the user's hand.

If the belt is made of fabric reinforced or other multi-layered backing, the coating may be selected in a manner that allows for particular optics and / or durable printability without compromising the tensile strength of the belt high material costs is required. Belts made of multi-layer material also allow individual coloring of at least the visible outside in connection with a printing or even without printing. The producible holding forces therefore do not suffer from the printability of the outer layer. On the other hand, the outer layer can be selected to be comparatively thin, so that even if it contributes little to the strength, it requires only a minimum amount of material. Fabric coated with PVC on both sides has proved to be particularly advantageous, PSE fabric (polyester fabric) being particularly preferred as the fabric. As a PVC coating, a so-called soft coating, in particular in a thickness between 0.5 and 2.0 mm per coating side is preferred. Soft coating is understood in particular as meaning a PVC coating which contains a phosphate-containing plasticizer; weight proportions of 10 - 30% are preferred such a plasticizer. The PVC coating may additionally contain flame retardants and / or color pigments.

If the loop, at least on your visible side, consists of dyed material, in particular colored PVC, in a signal color, this not only increases the safety for the passenger, because he discovers the position of the handle more quickly, but also achieves an improved advertising effect. In addition to the colors preferred for printing white tones, especially bright colors are considered as signal colors, such as signal red, signal yellow, signal orange, signal green, magenta and others. The latter are especially suitable for the "inside" of the wrist strap.

If at least the visible outside of the loops receives a coating of thermoplastic material, in particular if a PVC coating of thermoplastic PVC is chosen, this will cause i.a. opens up the possibility of making strips which can be processed as holding straps, cut from wider webs, at their cut longitudinal edges by e.g. form thermomechanical shaping as so-called soft edges.

For printing a variety of printing methods can be selected, with a pressure in the so-called Saugtischverfahren (flatbed machine with standing under vacuum printing table) ensures a particularly high print quality and durability of the print. In this method, the substrate to be printed rests on a flat surface and a push button bends in the X direction and the base in the Y direction. The printing is preferably done in digital technology.

Particularly preferred for printing are light-curing, in particular UV-curing inks. These have proven to be particularly durable in conjunction with the flexibility of the loop material and the high loads from constant touching and deformation of the loops. AIs further printing techniques particularly preferred is the printing in jet technology, in which a large number of points in a row in separate Druckflüssig keits rays is applied to the substrate. This is done in the piezo technique.

If at least the printed side of the loops has a coating layer (after the printing layer), the resiliency is thereby obtained for a particularly long time. Such a coating layer is preferably e.g. from clearcoat. UV-curing clearcoats fulfill the protective purpose particularly well and ensure a particularly attractive optical brilliance. A preferred layer thickness for the, preferably transparent, coating layer is in the order of magnitude of 10 μm.

A PVC coating is particularly useful because the handles are subject to considerable chemical stress and contamination when used with dirty hands or sweat from the hands. Relatively long lasting aesthetics and good printability are achieved by suitable material selection for the surface, e.g. through a PVC coating.

In order to adapt relatively wide handles with their comparatively large attack surface for the hand of a user to hygienic needs, it is proposed that at least portions of the surfaces of the belt comprise antibacterial material. As such, it is generally possible to provide the entire strap material with an antibacterial finish, but it is usually sufficient to incorporate or apply antibacterial material to the surface, it being sufficient to provide those strap portions in this manner, which are usually provided by the hands of a user. be attacked.

Preference is given to qualities having a tensile strength of> 2000 N / 5 cm, preferably 4000 N / 5 cm and more. Despite the individual design of the handles and the possibly relatively short period of use in comparison to handles not used as advertising media, compliance with safety standards is important. Experiments have proven that handholds having the aforementioned or claimed features, even the strict European safety standards for local passenger transport can meet, without the grab handle significantly more expensive. To mention here are aspects of smoke or fire protection and the strength under such extreme loads.

The abovementioned and the claimed components to be used according to the invention described in the exemplary embodiments are not subject to any special exceptional conditions in terms of their size, shape design, material selection and technical design, so that the selection criteria known in the field of application can be used without restriction.

Further details, features and advantages of the subject matter of the invention will become apparent from the dependent claims, as well as from the following description of the accompanying drawings and table, in which - by way of example - an embodiment of a handle is shown.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

From Figure 1, a generally designated 10 handle is visible, which serves as a retaining loop in vehicles and a one-piece belt 12 of a flexurally elastic material and one of two, identical in the example, identical half-shells 14A, 14B existing version. In a conventional manner, the one-piece belt 12, which is bent in the form of an eight, forms a first loop 12A which forms the actual handle, and a second loop 12B for attachment to a support of the vehicle.

As can be seen from FIGS. 2 and 3, in the region of the half-shells 14A and 14B, the strap 12 has perforations 13 for the passage of a central holding block 17 which is centrally arranged on the inside of the half-shell 14A and that of the half-shells enclosing receiving space for the belt 12 in the belt holes 13 passes through. The opposite half-shell 14B has at a location corresponding to the holding block 17 a receiving block 17B, which carries two holding elements 16A, 16B. These are in the illustrated and so far preferred embodiment of a peg-shaped and can be inserted into holding element receptacles 17A of the holding block 17, so that the holding block 17 is fixed at its freely projecting end to the opposite half-shell 14B. - Basically, the at least one holding element and its inclusion on or in the holding block 17 can be realized in various ways. - In the illustrated embodiment, two holding elements 16A, 16B in the belt longitudinal direction, as preferred, arranged at a mutual distance one behind the other. Between them is at its receiving block 17B, a reinforcing means 19A arranged (Fig. 2B) which is, for example, annular and cooperates with a corresponding configuration on the projecting front end of the holding block 17. Both the holding block 17 and the receiving block 17B have a through hole which between the positions of the holding elements 16A and 16B and the associated holding element receptacles 17A and can serve as a receiving means for a breakaway, as for receiving a bolt or a blind rivet, if with particularly high forces acting on the belt mount forces to be expected, leading to a tearing of the The socket could result from the perforation or otherwise bursting open the socket. A weakening of the belt is not caused despite this additional security option. The forces to be transmitted to the belt perforations are concentrated on the single holding block 17. Here, an approximately oval cross-sectional shape of the holding block 17 is to be mentioned, through which a belt width only relatively low occupying belt perforations and at the same time a low risk of tearing for the belt at the perforation edge is required. Incidentally, the projecting length of the holding block 17 can be freely selected. For example, from each of the half-shells, a sub-block may protrude inward and penetrate the belt holes by a corresponding amount, while the at least one retaining element may be provided on the one sub-block and its receptacle on the other sub-block. The recording block 17B shown, inter alia, in FIGS. 2B and 3L can therefore be extended to form a sub-block.

The inner sides of the half-shells 14A, 14B have in the illustrated and so far preferred embodiments clawing means 23 for impressing in the adjacent Belt surface on. These catching means are preferably combined like a strip (strip 23B) and leave, in the transverse direction of the belt, spaced-apart recesses 23A, the fiber strands (not shown in the drawing), which are incorporated in the belt 12 and arranged longitudinally at a lateral distance from each other can overlap. With such an association between the claw means or the intervening recesses and such fiber strands, the fiber strands remain largely unencumbered by the forces emanating from the frame and thus also unattenuated.

The claws carrying the claws 23B of the two half-shells are in the embodiments of Figures 2 and 3 (seen in the belt longitudinal direction) offset from each other, which u.a. may cause a certain waviness of the belt in the frame and serves to further power between socket and belt. The claw means 23 are truncated to reduce the notch effect on the belt. The socket half shells 14A, 14B have ball-shaped mouth ledges 24A, 24B at the entry and exit edges of the belt to minimize scoring and shearing forces on the belt 12. Springy latching connection means 25A, 25B on the narrow sides of the socket enable a quick and secure connection of the half-shells 14A, 14B usually without auxiliary tools and sufficient for securely closing the socket and fixing the belt in many applications.

In the illustrated in more detail embodiments of Figure 3 further features are provided:

Figs. 3A to 3H show a half-shell 14A of a holding belt socket. Fig. 3A shows the various cutting positions, Fig. 3D perspective views from the inside and Fig. 3F from the outside and Fig. 3B shows a narrow side and Fig. 3C is an end view. FIGS. 31 to 3P show the second half-shell 14B, wherein FIG. 3I shows the cutting positions and at the same time an inside view, while FIGS. 3L and 3N show perspective views as an inside and outside view. Fig. 3J is a narrow side view and Fig. 3K is an end view.

3Q to 3W show the socket in an assembled view, wherein FIG. 3Q shows the cutting positions and FIG. 3T shows a perspective view and FIG. 3R shows a narrow side view and FIG. 3S shows an end view.

In Figs. 3A to 3W, the same reference numerals have been used as in Figs. 2A to 2C. In the following, only the special features of FIGS. 3A to 3W are explained in comparison with the embodiment according to FIGS. 2A to 2C:

On the narrow sides of the half-shell 14A, web-shaped clawing means 26 are provided on the inner side, which extend transversely to the longitudinal belt edges. These serve as a Randverkrallungsmittel with the belt 12 (Fig. 3C and 3S) and on the other hand increase the bending stiffness of the paired connecting means 25A and 25B of the two half-shells 14A and 14B.

The claws 23 carrying strips 23 B of a half-shell (14 A) are of different heights, as shown in FIGS. 3C and 3E. Their height, with which they protrude into the socket interior increases towards the belt edges and thus to the connecting means 25A. Thereby, the belt surface is subjected to some bending in the transverse direction of the belt, which is assisted by the fact that the opposing half-shell 14B is in this area e.g. wear shorter strips 23B with claw means 23 and claw means close to the belt edge - and thus close to the connecting means 25B - missing or comparatively low.

As can be seen, one belt section after the other has to be inserted into the first half-shell and the second half-shell must be inserted from the opposite side to mount the handle. Set side are pushed until the connecting means 25A, 25B lock together. This is possible without tools and safely carried out by a non-trained assistant. Unauthorized disassembly without tools is preferably prevented. The half-shells of the socket are usually not reusable and are preferably rejected for safety reasons, especially since these are very inexpensive and recyclable components. The large visible surfaces of the half shells can also be used as advertising space. This is possible by printing, in-mold labeling or inserting printed material behind a viewing window.

As can be seen from FIGS. 4A-H, the strap 12 of a handle, which can be made of a material as explained in the preceding examples, consists of an elongated belt section, whose mutual end regions (outer end region 12B "and inner end region 12B ') The inner end region 12B ¹ (FIGS. 4B / 4C) has a smaller spacing of the associated perforations 13.2, 13.3 in such a way that the two end regions are in mounting situations for the socket (FIG. 4C - 4G) are exactly aligned with one another and at the same time the belt end regions abut one another along their entire length, at least in the state of use. wherein the dimensioning of the socket to the enlarged by the fourth strap piece package thickness i m range of the socket is adapted. The height of the holding block 17 is shown in Figures 4D and 4E, for clarity, exaggeratedly long. In practical terms, he does not go beyond the tapping 13.4.

When the half-shells 14A and 14B are joined together via the loop ends inserted into them (Figure 4F), the package can be compressed by means of a pincer-like tool until the engagement of the connecting means 25A, 25B. The remaining perforation (receiving means 19 B) in the central socket area, which the holding block 17 passes through, can be used in case of need to enforce a blind rivet. At its head end, the holding block is provided with pressure pieces 17C, which can give the pressure of a blind rivet in case of need, in order to increase the contact pressure of the socket on the belt.
