Description

TITLE

Hand strap for a stick handle TECHNICAL AREA

The present invention relates to a hand strap for a pole grip, in particular for walking sticks, trekking poles, alpine skis, cross-country poles, Nordic walking poles, with a handle body and usually with a device for adjustable attachment of the wrist strap. Furthermore, the present invention relates to a pole grip with such a hand strap.

PRIOR ART So that the user does not have to hold a pole constantly for the above-mentioned application areas and also does not lose it when the pole grip once slides out of the hand, such pole handles have a hand strap. By such a hand strap, the user typically grips with his hand, so that in use, the wrist strap then typically runs over the back of the hand in the area of the wrist and lies on the inside of the hand in those areas which are guided into the pole grip.

Such stock loops are typically configured adjustable, for example by the hand strap is attached via a screw or a wedge on the pole handle, and the screw or the wedge provides an easy way to adjust the length of the wrist strap as possible without the aid of a tool to the needs of the user , Such mechanical devices should be as reliable as possible, and do not permit undesirable adjustment of the length of the loop during use. They should also allow adjustment without complicated manipulation, and they should be extremely simple in their construction to keep costs down. On the other hand, such attachment mechanisms, this is particularly important in the alpine area very important to be able to perceive this releasable locking function in the widest possible temperature range.

Such a construction is for example from German Utility Model DE 681 01 226 Ul known. There, a loop on the floor is adjustably fastened by the loop tape is guided around two pins in the attachment area in the floor. This via a tiltable element, which is arranged at the head of the stick handle, and in which these two pins are arranged. If this tilting element is folded upwards out of a recess in the pole grip, the length of the hand strap can be adjusted. If the tilting element is at least partially folded back down into the pole grip, the length of the hand strap is fixed.

In addition, there are solutions in which with the aid of a slotted region of the loop band, the adjustability is then given when the hand strap is moved up, while in downward hand strap the hand strap is fixed in length. Such possibilities are described for example in DE 19632718, DE 29906612 Ul, and the like in EP 1118362.

Further such constructions for adjustable hand loops are known from WO 2006/084403, and a particularly ergonomic handle, which may also have an adjustment mechanism for the hand strap, is known from EP 2168641.

Thus, the hand strap is able to withstand the sometimes large tensile loads and thus the above-mentioned adjustability can be made possible, the hand strap must be made of a tensile material. Typically, such loops are accordingly made of a wide webbing or a wide leather strap, which may optionally have patches of a soft material.

As explained above, hand straps must, on the one hand, absorb high tensile forces without being elastically deformed, which in turn requires particularly tensile but nevertheless flexible materials, but on the other hand, they are brought into intensive contact with the hands and thus the perspiration when used sportily. Accordingly, this moisture or moisture in the belt tapes usually used in the prior art in this contact area can not be dissipated, and accumulates, which on the one hand to increased slip behavior, on the other hand, but also cause skin problems. These problems can only be partially explained by the patches also used in the prior art Avoid a moisture absorbing material, since such materials are already completely saturated after a very short time, especially in intensive use and can not fulfill their task.

Here, the invention intervenes and proposes an improved pole handle, in particular for walking sticks, trekking poles, alpine skis, cross-country poles, Nordic walking poles, with a handle body and with a device for fixing a strip or band-shaped wrist strap before.

Such a pole grip according to the invention is characterized in that the hand strap in the coming into use in contact with the user's hand area two lateral, substantially the outer edge of the wrist strap in this area forming and substantially inelastic edge strips which perpendicular to the direction of the Hand strap are spaced from each other, and that the area lying between these edge strip is formed by a permeable strip of material. The edge strips are inelastic in the pulling direction of the wrist strap and tensile strength, perpendicular to this they can be elastic / stretchable (but need not).

The essence of the invention is accordingly to limit the absorption of the tensile forces on the edge areas and to provide between them an area in the form of a permeable strip of material that connects these inelastic edge areas and keeps at the correct distance, but on the other hand, as permeable, the means that moisture in this area can not accumulate or can be transported through the loop. In contrast to known solutions, where to some extent the tensile forces are absorbed by a single narrow strip in the central region and widening improve the application of force to the hand, and where then either these extensions are soft and accordingly can not take over the distribution of forces well or very stiff must be trained to allow the distribution of forces but then are uncomfortable to use, the proposed new hand strap leads to a very pleasant structure that does not apply and is very flexible but still in use optimally applied to the hand and also at intensive use does not create an unpleasant feeling of dampness.

Typically, the edge strips, which are normally of mirror-symmetrical configuration, have a width (measured perpendicular to the main course of the hand strap) in the range of 2-10 mm, preferably in the range of 4-7 mm. The edge strips preferably extend over a substantial portion of the length of the hand strap, where contact with the hand is substantially parallel.

Typically, the permeable area resp. Material strip over a width (measured perpendicular to the main direction of the hand strap) in the range of 5-50 mm, preferably in the range of 10-30 mm.

According to a preferred embodiment, the permeable strip of material is not only permeable to air and permeable to moisture, but preferably also liquid-permeable. It may preferably be at least one layer of a braided and / or woven textile material, but it is also possible foamed materials or the like.

A particularly comfortable feeling and at the same time a hand strap, which is not excessively stiff perpendicular to the main course direction, can be achieved if the permeable strip of material is elastic (in contrast to the edge strips, which should be specifically targeted as inelastic). In this case, the permeable material strip preferably has an elastic extensibility of more than 1%, preferably more than 5%, in particular preferably more than 10%. Such extensibility values are preferably perpendicular to the course direction, or in both directions, that is, perpendicular and parallel to the direction of the hand strap. In contrast, the edge strip preferably has an elastic extensibility of less than 5%, preferably less than 2% or less than 1% in the pulling direction of the wrist strap.

The permeable strip of material may be formed from a layer, but it may also be composed of at least two layers. In addition, one or more intermediate layers may be arranged between such two layers.

A further preferred embodiment is characterized in that the edge strip is one or more edge seams executed in the edge region of the permeable material strip, for example a tightly guided zigzag seam, which makes this edge region inelastic. In other words, the edge region does not necessarily consist of a separate strip material or strip material, but can be formed to some extent from such a seam or suture from the edge region of the permeable strip of material.

Alternatively, the non-elastic region of the loop can be formed, for example, by means of low-stretch (round) cords or braids, which result in the seaming of the edge region let in, fastened by a seam or sewn on the opposite side (outside of the hand). For example, in the form of a known in textile processing piping, but not only can be taken in a fabric tape but also can be simply sewed on or.

A further preferred embodiment is characterized in that the edge strip is a strap strip folded around and around the edge region of the permeable material strip and sewn and / or glued to the permeable material.

Alternatively, it is possible to use two webbing strips arranged on the opposite sides of the permeable material strip and sewn together and / or glued to one another and to the permeable material strip.

Preferably, such a hand strap is adjustably mounted in the handle. Preferably, the fixed attachment region of the wrist strap and the adjustable region of the wrist strap are formed in the form of a webbing extending over the entire width of the wrist strap, that is, there is no permeable strip of material in these regions. This can be achieved, for example, by sewing that area with the permeable strip of material and the edge strips at each end with a strap section. One of these sections then serves at one end of the wrist strap for fixed attachment to the handle, and the other portion forms the free end guided by the handle in the adjustment area. Since most adjusting mechanisms are based on a clamping of the strap of the wrist strap, in these areas the permeable and thus usually elastic material strip is often disturbing.

The permeable strip of material may for example consist of at least two woven textile layers with holes in the weave structure. These may well be holes of the order of 0.5-2 mm to ensure excellent permeability. Such layers can be used in different colors, so that through the holes a translucent effect can be achieved.

Furthermore, transverse webs, preferably made of an inelastic material, can be provided between the two edge strips, offset along the direction of progression, in order to further ensure the optimum spacing of the two edge strips. These transverse webs may for example be formed of the same material as the edge strips respectively together with these into a sewing process. But the transverse webs may for example also be formed by a webbing material, while the edge strips are formed by a further material. A preferred embodiment of the invention is characterized in that the area of the wrist strap coming into contact with the palm of the user is formed of a layer of breathable material, followed by a layer consisting essentially of transverse webs, preferably zigzag-like from one edge strip to the other, followed by a net-like layer as a cover layer. In this case, the edge regions of all layers are preferably comprised of an edge strip, which in turn is preferably formed of another material.

The edge strips are preferably formed from a plastic material, but may also consist of leather with low elasticity. The edge strips may for example consist of or contain a polyamide or polyester material, aramid, Dyneema or other low-expansion material or combinations thereof. The edge strips are preferably in plaited and / or woven form. The permeable strip of material preferably comprises at least one layer of a woven and / or braided and / or foamed and / or non-woven plastic material. In particular, the above-mentioned intermediate layers may for example consist of a foamed (open-pore) or non-woven material for the permeable material strips are preferably plastic materials such as polyamide, polyester, polyethylene, chloroprene or combinations thereof in question, but there are also natural materials such as soft and accordingly permeable and flexible leather, or natural woven or braided materials such as cotton etc. possible.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

Figure 1 shows a side view of a stick handle 1 with a breathable hand strap according to the present invention. The pole grip 1 has an actual handle body, in the lower region of which a receiving opening for the actual pole tube 2 is arranged. The grip region 4 of this grip body is typically coated with a grip-friendly coating. In the region of the handle head 3, the wrist strap is attached, in this case screwed with the end shown above firmly in a recess in the handle head 3 and adjustable in the lower end. For this purpose, an eccentric element is mounted on the axis 8 in the head region, specifically, this is an adjusting mechanism, as described in WO 2006/084403. With regard to the adjustment mechanism, the disclosure of this document is expressly included in the disclosure of this application. As far as the basic design of the handle is concerned, reference is made to EP 2 168 641, the disclosure of which should also be included in the present disclosure with regard to the geometric configuration of the pole grip.

The actual hand strap 5 is formed in that region which circulates in use the user's hand, such that there are two lateral and the edge of the hand strap forming inelastic edge strips 6, and between these two edge strips, which typically have a smaller width than that Intermediate area, a permeable strip of material 7 is arranged. This permeable strip of material 7 on the one hand has the function, the two edge strips 6 in the On the other hand, the material strip 7 is breathable, ie permeable to air and permeable to moisture, typically also liquid-permeable. But it is also possible, for example, to provide a functional membrane (breathable and liquid impermeable) in this area. In any case, the assumption of tensile forces on the wrist strap is taken over essentially exclusively by the two lateral edge strips 6, but not by the elastic permeable material strips. 7

Since such an elastic regions 7 comprehensive stripe construction can not be attached particularly well in the grip head 3, nor can be used in the adjustment in the clamping range, this is to some extent middle portion of the wrist strap at one end (shown in Figure 1 above) with a conventional Sewn webbing area 15 or eg connected by weaving with this. The not visible in Figure 1 and projecting into the recess of the pole grip end of this extending there over the full width webbing 15 is fixed, for example, with a screw fixed to the pole grip. At the other free end of the breathable designed loop area such a conventional webbing 15 is also arranged. This passes through the clamping adjustment mechanism inside the pole grip and then exits from this as a free end 9 out. At the outermost end, a widening 10 can be provided for simplified manipulation.

In Figure 2, different exemplary embodiments of such a breathable loop construction are now shown, with each section are shown perpendicular to the main course 11 of the hand strap. Here it can be recognized, for example, how the two lateral edge strips 6 (cf., FIG. 2 a) can be designed in the form of edge seams of the permeable material strip 7. These edge seams cause inelastic edge strips to form, and such a construction can be made in a simple manufacturing process.

The permeable material strip 7 can, as shown in Figure 2b, not only have a single permeable material layer, but a plurality of layers, here for example two. In this case, these two layers can be formed, for example, from a fabric with rather large holes, and when the two layers are then selected from two different colors, the result is an interesting optical effect, which differs depending on the viewing angle. As shown in Figure 2c, the respective edge strip but not only in terms of zigzag sewing (and possibly Längsvernähung), which is very tight, be formed, but it can also at the edge on the top and on the bottom two narrow strip of tape 12 are arranged, which are then sewn with a seam 13 and glued to the permeable material strips 7. It is also possible to only glue all the layers or to guide the seam 13 through the two tape strips 12 such that at the same time the permeable material strip 7 is fixed by this seam. A combination of gluing and sewing is possible.

In principle, care should be taken that in such a construction, the material of the tape strip 12 is not too thick, so that the transition from the edge strip 12 to the permeable strip of material 7 is not too strong paragraph. Accordingly, such edge strips 12 should preferably be formed of a thin webbing having a thickness of less than 2 mm, preferably less than 1 mm.

It is also possible, in a slight modification of Figure 2c, not on both sides (outside and inside) to provide two such strips of tape 12, but only one, and this either only on a surface to arrange (preferably on the outside relative to the User's hand), or to some extent to fold this strip around the peripheral edge and then connect to the permeable strip of material.

Figure 3 shows two different exemplary embodiments in each case in a plan view of the area that comes into contact with the hand. In FIG. 3 a, that design is shown, as it is also shown in FIG. Here, the two edge regions 6 are exclusively connected to one another via the permeable material strip 7. In Figure 3b is shown that it is also possible to provide between the two edge strips still perpendicular to the direction 12 transverse webs 14, in which the permeable strip of material is arranged. Basically, it is also possible to use a wide webbing strip as a starting material, then to some extent windows, which are separated from each other by such transverse webs 14, auszustanzen from this webbing and anschießend in or above these windows to arrange the material strip 7. The permeable strip of material can be attached either actually in the form of a strip on such a grid, but it is also possible, then in each case only the window with such a permeable material, respectively. with a Multi-layer structure of such a permeable material to close.

In this case, these windows can also be designed in the form of regular round perforations (for example a row as shown in FIG. 3c), but several rows are also possible), in the form of two rows of oppositely directed and interlocking triangles (delta frames See Figure 3d), realized for example by zigzag arranged transverse webs 14, or in the form of honeycomb structures as shown in Fig. 3e).

In general, a sandwich construction is possible by, for example, the following layers in the following order are connected to each other: breathable material, webbing, breathable material, and outside and / or possibly further layers and other intermediate layers.
