Abstract

A cut protection (1, 41, 61) has a plurality of protective layers (21, 22, 23, 51, 52, 71), wherein a first protective layer (21, 51, 71) has a smooth, slippery surface (21, 51, 71) on at least one side (24). 26, 46). A second outer protective layer (22) rests on the smooth, slippery surface (26, 46). The second protective layer (22) consists of an elastically extensible material (27) and is at least partially displaceable relative to the first protective layer (21, 51, 71).

Description

The invention relates to a cut protection, in particular a cut protection for a hand saw, the saw blade is moved in a working direction along the saw blade back and forth.

From the DE 200 04 654 U1 is a protective glove, especially for chainsawing known. In the back of the glove, an intermediate layer is also provided with highly tear-resistant yarn, which is folded once or several times and in which the chainsaw is to be caught and thereby braked.

The invention has for its object to provide a cut protection, which has a simple structure and offers a good protection against cuts when working with a manually operated saw.

This object is achieved by a cut protection with the features of claim 1.

It is envisaged that rests on a first protective layer with a smooth, slippery surface, an outer, second protective layer, which consists of an elastically extensible material. The outer protective layer is at least partially displaceable relative to the protective layer with the smooth, slippery surface. Thereby, a tooth of the tool, for example a saw, hook on the elastically extensible material and take along the elastically extensible material and thereby move against the smooth, slippery surface at least in a region of the elastic material. This will the kinetic energy of the tool, in particular the saw, at least partially absorbed and the tool is braked. The elastic material slips in this area together with the saw on the smooth, slippery surface of the first protective layer.

When working with a manually operated tool such as a hand saw, the tool is usually moved in one direction back and forth. During the working stroke, the teeth of the hand saw penetrate into the material to be cut and chop the material to form a kerf. The working stroke requires a comparatively high amount of effort on the part of the operator. The return stroke is done with higher speed and less effort.

If, for example, the saw slips out of the kerf during the working stroke and comes into engagement with the cut protection, the elastically extensible material of the second, outer protective layer brakes the movement of the handsaw. The teeth of the handsaw snag in the elastic material and are slowed down by the energy needed to stretch the elastic material. The elastically extensible material is tensioned like a spring and thereby exerts a kind of restoring force on the saw, which also brakes the saw. The hand saw slides over the smooth, slippery surface. The teeth take advantage of the elastic, stretchable material. Because the kinetic energy of the tool is at least partially absorbed by the elastically extensible material, further layers of the cut protection, in particular a planer protection of the cut protection, can be made with a smaller thickness. The layers need only be designed to absorb a portion of the kinetic energy of the tool, since some of the kinetic energy is already absorbed by the second, outer protective layer. Even if the saw passes in a movement obliquely to the working direction in engagement with the cut protection, the saw is braked in the manner described and the kinetic energy of the saw is absorbed by the second, outer protective layer.

For example, if the saw slides on the return stroke, ie if the handsaw is moved in the opposite direction to the direction of movement during the working stroke, it leaves the kerf and enters Intervention with the cut protection, so the elastic material is cut by the hand saw. However, penetration of the teeth into the underlying first protective layer is largely avoided on account of the smooth, slippery surface of the first protective layer. The saw slips over the first protective layer. The first and the second protective layer thus offer a simple and effective protection, especially when working with a manually operated saw, ie a hand saw such as a hacksaw, a tree care saw, a foxtail or the like.

The elastic, stretchable material of the second protective layer and the nature of the first protective layer are advantageously chosen so that the sliding friction coefficient μ between the first and the second protective layer is at most 0.2, in particular at most 0.1. This ensures that the second protective layer can slide well on the first protective layer.

Advantageously, the stretchable material is fixed in an edge region of the material on the first protective layer. The fixing takes place in particular only in the edge region, so that the stretchable material is movable relative to the first protective layer in all areas spaced from the edge region and movable relative to the first protective layer. However, it can also be provided to additionally fix the stretchable material in middle areas of the cut protection on the first protective layer, for example by means of stitching seams provided at regular intervals. The distance between the stitching is advantageously chosen so large that the elasticity of the stretchable material in the area between adjacent seams is sufficient to brake a manually operated tool such as a hand saw sufficiently. The braking of a saw or other tool is achieved by the ability of the material to elastic stretching and not by a special arrangement of the material, for example by the arrangement of the material in multiple layers or in folds. The ability to stretch elastically is dependent on the type of fiber and the type of surface formation, such as training as a knitted fabric, woven or knitted fabric, but not on the nature of the arrangement of the protective layer. As a result, the elastic material can be provided as an outer protective layer and does not need to be covered by another, smooth layer become. The stretchable material is in particular a flat, textile material which is woven, knitted or knitted from extensible threads. The stretchable material may also be a film at least partially made of an elastic material. The stretchable material preferably contains elastane, elastic polyester or modal.

The smooth, slippery surface of the first protective layer is preferably at least partially formed by the surface of a woven, knitted or knitted fabric of a smooth yarn. The smooth, slippery surface is preferably at least partially formed by a paint-containing or plastic-containing paint or by a coating.

Advantageously, at least one protective layer is provided as planing protection. The planer brakes the movement of the tool during the working stroke, when the teeth of the tool engage in the planer guard. The kinetic energy of the tool is at least partially absorbed. It can be provided that the first protective layer forms the planing protection. However, it may also be provided a third protective layer, which is arranged on the side facing away from the second protective layer of the first protective layer and forms the planing protection. Between the first and the third protective layer, further protective layers can be provided. However, in order to achieve a low overall height of the cut protection, the third protective layer is advantageously applied to the first protective layer. In order to brake the powerful and planing movement of the tool, the planing protection advantageously consists of a tear-resistant, thick and dense fiber composite. The material of the planing protection comprises in particular a polyamide, for example an aramid, or an ultra-high molecular weight polyethylene such as Dyneema. Preferably, the planing protection is at least partially formed as a fleece, felt or fabric. Nonwovens, felts or fabrics have a dense fiber composite and can thereby brake the teeth of the tool well and at least partially absorb the kinetic energy of the tool. The elastic protective layer is stretched.

A simple construction is achieved when the cut protection has a plate-shaped basic shape, which is attached to the operator. The cut protection can be flat or be arched. The cut protection is advantageously formed dimensionally stable. Under the influence of the weight of the cut protection essentially retains its shape. The cut protection is advantageous so flexible that the cut protection can be bent by the operator with little effort and the curvature of the cut protection can be adapted for example with a fastening device such as a Velcro to the curvature of the body part of the operator to be protected.

The cut protection may be designed to protect different body parts such as the hand or leg or thigh of an operator. For attachment to the operator is provided that the cut protection has at least one fastening device. If the cut protection is provided to protect a hand, advantageously at least one fastening device is designed as a finger loop. As a fastening device may preferably be alternatively or additionally provided a Velcro. The cut protection has in particular in plan view of the second protective layer has an elongated basic shape, adjacent to its first narrow side a first fastening device, in particular a Velcro strip, and adjacent to its second narrow side a second fastening device, in particular a finger loop. About the attachment devices, the cut protection on the hand and arm or on the sleeve of the operator can be fixed. A design of the cut protection as a glove or the like is not necessary. The cut protection covers a user's hand favorably in the area of the back of the hand and the outside of the fingers. The palm of the operator remains advantageous largely, especially completely free. As a result, the operator is hardly hampered by the cut protection while working. The fingers remain largely free, and it ensures good airflow to the hand and arm. Other fastening devices may be advantageous for attaching the cut protection to the hand or arm of an operator.

If the cut protection is designed to protect another part of the body, for example a thigh of the operator, other fastening devices can also be used be beneficial. The fastening devices are advantageously adapted to the purpose and the mounting location of the cut protection.

Advantageously, the cut protection has at least one further layer in addition to the first and the second protective layer. The further layer may, for example, be a spacer layer, in particular a spacer fabric. In order to increase the rigidity and stability of the cut protection, the first protective layer with the at least one further layer, in particular with all other layers of the cut protection with the exception of the second outer protective layer, is sewn to at least one seam. In order to achieve a high rigidity, in particular several seams are provided at regular or different intervals. The rigidity of the cut protection can be suitably adjusted by suitably selecting the layers of cut protection sewn together, the number of seams and the distance between the seams. However, it may also be advantageous that all protective layers are interconnected only in their edge region. As a result, a high degree of flexibility and ease of manufacture of the cut protection are achieved.

In Fig. 1 a cut protection 1 is shown schematically. The cut protection 1 has a protective area 30, which is formed by a flexible, constructed of several protective layers material. The protection area 30 is plate-shaped and may be flat or curved. Due to the flexibility of the material, the cut protection 1 with its protection area 30 can adapt to the hand and arm of an operator in moderation. The protective area 30 is bordered at its circumferential edge by a bordering tape 4, which is fixed to the protective area 30 with a seam 3. However, the binding tape 4 can also be omitted. Fig. 4 shows a view of an outer side 2 of the cut protection 1. This outer side 2 is disposed away in operation to the outside and the hand of an operator. In the exemplary embodiment, the cut protection 1 is designed as a hand guard. However, the cut protection can also be designed to protect other body parts, for example as leg protection.

The cut protection 1 has an elongated, approximately rectangular basic shape. On a first narrow side 7 a Velcro strip 5 is provided for fastening the cut protection 1 on a sleeve of the operator. The Velcro hooks protrude to the outside 2, in Fig. 1 So from the leaf level up. The second narrow side 8 of the cut protection 1 is in operation adjacent to the fingers of an operator, as well Fig. 2 shows. On the second narrow side 8 of the cut protection 1 is rounded. Adjacent to the second narrow side 8, a finger loop 6 is provided, which in the illustration in Fig. 1 is below the protection area 30. In the exemplary embodiment, the cut protection 1 is designed mirror-symmetrically to a plane which contains a center line 9 of the cut protection 1 and is perpendicular to the plane of the protection area 30. Is the cut protection 1 to Provided protection of other parts of the body, it is advantageous to provide other or additional suitable fastening means.

The protection region 30 has a width e that is significantly smaller than a length d of the protection region 30. In the exemplary embodiment, the width e is about 9 cm to 18 cm and the length d about 20 cm to 30 cm. The cut protection 1 has a length c measured without the Velcro strip 5, which corresponds to the length d of the protective area 30 plus twice the width of the binding strip 4. The length c may be, for example, about 21 cm to about 35 cm. In the exemplary embodiment, the length c is about 25 cm. The cut protection 1 has a total length a, which is about 22 cm to about 40 cm. In the exemplary embodiment, the length a is about 28 cm. The cut protection 1 has a width b which corresponds to the width e of the protective area 30 plus twice the width of the bordering tape 4. The width b may be, for example, about 10 cm to about 20 cm. In the exemplary embodiment, the width b is about 15 cm.

Fig. 2 shows the cut protection 1 from its inside 10. The inside 10 is in operation adjacent to a hand 11 of an operator. In this case, the back of the hand of the operator on the inside 10 of the cut protection 1. The palm is facing away from the cut protection 1. The palm is not covered by the cut protection 1. By the finger loop 6 protrudes at least one finger of the operator. In the embodiment, the finger loop 6 is provided in the region of the center line 9 of the cut protection 1, and a middle finger 12 of the operator protrudes through the finger loop 6. There may also be other or additional fasteners for the cut protection 1, for example on other fingers of the operator or on the palm or the wrist, be provided. As Fig. 2 shows the fingers of the operator are outstretched hand on the second narrow side 8 on the cut protection 1 over. The thumb of the operator projects laterally over the cut guard 1. When the operator angles the fingers, for example, to hold a workpiece, the fingers of the operator are preferably largely covered by the cut guard 1. The back of the hand of the operator is completely covered by the cut protection 1.

Fig. 3 schematically shows the cut protection 1 with a manually moved by the operator saw 13. The cut protection 1 is curved, wherein the curvature is adapted to the curvature of the hand and / or the arm of an operator. The saw 13 has a handle 14 and a saw blade 15 fixed to the handle 14. During the working stroke, the saw 13 is moved by the operator in a working direction 16. The workpiece is machined and a kerf is produced in the workpiece. The saw teeth 17 of the saw 13 engage the workpiece. If, for example, the saw 13 slides out of the groove during movement in the working direction 16 and comes into engagement with the protective area 30 of the cut protection 1, then the teeth 17 engage in an outer protective layer 22 of the cut protection 1. The outer protective layer 22 is made of an elastic, sheet material formed, which is stretched by the saw 13. The elastic material behaves similar to a spring and is stretched by the saw 13. In this case, the kinetic energy of the saw 13 is reduced, and the saw 13 is braked. The elastic material exerts due to its tension a kind of restoring force on the saw 13, which acts counter to the working direction 16. As a result, the saw 13 is additionally braked. In a lateral movement of the saw, for example, obliquely or perpendicular to the working direction 16, the saw 13 is slowed down under strain of the elastic material accordingly. If, for example, the saw 13 slides out of the kerf during a movement in the opposite direction to the arrow 16, ie during the return stroke, then the back sides of the saw teeth cut through the second outer protective layer 22.

Fig. 4 schematically shows the structure of the cut protection 1. The cut protection 1 consists of a first protective layer 21, on which an outer, second protective layer 22 is located. At the first protective layer 21 facing away from the outer second protective layer 22, a spacer layer 23 is arranged. In its edge region 20, the protective layers 21, 22 and 23 are joined together by the seam 3. In the embodiment, the bordering tape 4 is additionally provided, which covers and embraces the edge of the protective layers 21, 22 and 23. The outer protective layer 22 forms the outer side 2 of the cut protection 1. The outer, second protective layer 22 consists of an elastic, stretchable material 27. The material 27 is a flat, woven from stretchy threads, knitted or knitted textile material. The second protective layer 22 is formed by a single layer of the material 27, which is smooth and without wrinkles on the first protective layer 21. The elastic, stretchable material 27 may also be a film at least partially made of an elastic material. The elastically extensible material 27 preferably contains elastane, for example Lycra. The elastically extensible material 27 may also include elastic polyester, modal or the like. The elastic material 27 is advantageously stretchable by at least about 50%, in particular by at least about 80%, preferably by at least about 100%. The elongation of the elastic material 27 is in particular less than 300%. The elastic material 27 has no cut protection effect, but is in a return stroke of the saw 13 against the working direction 16 ( Fig. 3 ) cut through smoothly.

The first protective layer 21 has on its outer side 2 of the cut protection 1 side facing 24 a smooth, slippery surface 26. In the exemplary embodiment, the surface 26 is at least partially formed by a smooth layer 31. On its side 10 facing the inside 10, the first protective layer 21 rests on the spacer layer 23. The first protective layer 21 is formed in the embodiment of several strips of material 28, which overlap at their longitudinal edges 29. In a further advantageous embodiment, the strips of material 28 are arranged with their longitudinal edges 29 adjacent to each other, so that the longitudinal edges 29 abut each other and results in a continuous surface. Advantageously, the strips of material 28 are not connected to each other at their longitudinal edges 29. By forming the first protective layer 21 from individual, adjacent strips of material 28, a high flexibility of the first protective layer 21 is achieved. However, it can also be provided that the individual strips of material 28 are sewn onto a base material. It can also be provided that the first protective layer 21 is formed by a single piece of material and not by individual strips of material.

The first protective layer 21 has a carrier material 19, which is formed in the embodiment as planing protection and on which the smooth, slippery surface 26 is arranged. The carrier material 19 is advantageously a material made of a tear-resistant, thick and dense fiber composite. The support material 19 is at least partially as a fleece, felt or fabric educated. The carrier material 19 may be, for example, a woven belt material, wherein the width of the material strip 28 corresponds to the belt width.

The material of the planing protection comprises in particular a polyamide, in particular an aramid or an ultrahigh molecular weight polyethylene, in particular Dynema. The carrier material 19 may be formed from a smooth, stable yarn. The smooth, slippery surface 26 is advantageously formed from the protruding to the surface 26 portions of the smooth yarn of the substrate 19. Alternatively or additionally, on the side 24, a coating or a coating may be applied to the carrier material 19, which is in particular plastic-containing or lacquer-containing. The smooth, slippery surface 26 is advantageously formed by the coating or the paint. However, it can also be provided that the smooth, slippery surface is formed by a woven, knitted or knitted fabric of a smooth yarn, which is arranged on the substrate 19 and is connected thereto, for example by gluing or laminating. The smooth, slippery surface may also consist of a combination of these designs.

The smooth, slippery surface 26 and the elastic material 27 are advantageously designed and matched to one another such that the sliding friction coefficient μ between the surface 26 of the first protective layer 21 and the material 27 of the second protective layer 22 is at most 0.2, in particular at most 0.1 ,

The protective layers 21, 22 and 23 are connected to each other in their edge regions 20 by the seam 3. In order to achieve a simple construction and a high flexibility of the cut protection, the protective layers 21, 22 and 23 are interconnected only in their edge regions 20. To increase the rigidity of the cut protection 1 can also be provided that the protective layers 21 and 23 are additionally connected to each other in the protection area 30, for example by further seams. The distance between the seams may be, for example, about 2 cm to about 10 cm, advantageously about 4 cm to about 6 cm. The distances between adjacent seams can be the same for all seams. However, different seam spacings can also be advantageous.

The spacer layer 23 advantageously has a plurality of ventilation openings and serves to improve the circulation of air on the inside 10 of the cut protection and thus to increase the wearing comfort. The spacer layer 23 may be, for example, a spacer fabric.

As Fig. 1 shows, the protection area 30 extends over the entire area, which is bordered by the binding tape 4. In the in Fig. 5 shown section, so in a section in the transverse direction of the cut protection 1, only one strip of material 28 is shown. The material strips 28 extend in the transverse direction of the cut protection 1. The protective region 30 has a total thickness f, which is advantageously from about 2.0 mm to about 15.0 mm, in particular from about 3.0 mm to about 10.0 mm. The total thickness f is measured in the protection area 30. In the schematic illustration, the thickness of the cut protection 1 is constant over its entire width. However, the thickness of the cut protection 1 can be reduced in the region of seams, in particular on the binding tape 4, since the protective layers are compressed by the seam 3. The protective layers 21, 22 and 23 are connected to each other in their edge region 20 by the circumferential seam 3. The protective layer 22 is advantageously attached to the protective layer 21 only in the edge region 20 and movable in the protective region 30 relative to the protective layer 21. Advantageously, all protective layers are connected to each other only in the edge region 20. Due to the fact that the protective layers are limitedly movable relative to one another, a high degree of flexibility of the cut protection 1 results. To increase the rigidity, the protective layers 21 and 23 can, however, additionally be connected to one another in the protective region 30, in particular by additional seams. Also, other than the second protective layer 22 provided additional protective layers may be connected by the additional seams with the protective layers 21 and 23. This results in an increased stability of the smooth, slippery surface 26, whereby penetration of a tool into the smooth, slippery surface 26 is largely prevented.

Fig. 6 shows the thicknesses of the individual protective layers 21, 22, 23 schematically. In the figures, the individual protective layers for better visibility are shown at a distance from each other. In the actual embodiment, the individual protective layers 21, 22, 23 together. The thickness f of the protective region 30 is composed of the thickness g of the outer protective layer 22, the thickness p of the first protective layer 21 and the thickness k of the spacer layer 23. The thickness g is advantageously from about 0.2 mm to about 2.0 mm , The thickness p of the first protective layer 21 is advantageously from about 0.3 mm to about 3.0 mm, in particular from about 0.5 mm to about 2.0 mm, preferably from about 0.8 mm to about 1.0 mm. The thickness p is measured in a range in which the longitudinal edges 29 of the material strips 28 do not overlap. The thickness p thus corresponds to the thickness of the material strip 28. The thickness p is approximately composed of the thickness h of the smooth layer 31 and the thickness i of the substrate 19. The smooth layer 31 is, for example, a coating applied to the substrate 19 or a coating the substrate 19 applied paint. The thickness h of the smooth layer 31 may vary, wherein the smooth layer 31 advantageously at least partially fills depressions in the carrier material 19. The thickness h is advantageously up to about 1.5 mm. In this case, the smooth layer 31 may be interrupted in places, ie have a thickness of 0 mm. The smooth surface is accordingly formed by the carrier material 19 and the smooth layer 31. The thickness i of the carrier material is advantageously from about 0.3 mm to about 3.0 mm.

The spacer layer 23 has a thickness k, which may advantageously be from about 0.5 mm to about 10.0 mm, in particular from about 2 mm to about 8 mm, preferably about 5.0 mm. A greater thickness of the spacer layer 23 results in improved air circulation and thus increased wearing comfort. At the same time a padding of the cut protection 1 is achieved by a large thickness of the spacer layer 23.

Fig. 7 shows an embodiment of a cut protection 41, which has a protection area 50. The protective area 50 comprises a first protective layer 51, a second, outer protective layer 22 and a third protective layer 52. In addition, a spacer layer 23 is provided. The structure of the outer protective layer 22 and the spacer layer 23 corresponds to that of the previous embodiment. The first protective layer 51 has a smooth, slippery surface 46 on which the elastic, stretchable material 27 of the outer protective layer 22 can slide and move relative to the first protective layer 51. The third protective layer 52 forms a planing protection and is at least partially formed as a fleece, felt or fabric. The material of the planing protection comprises in particular a polyamide or an ultra high molecular weight polyethylene and advantageously consists entirely of polyamide and / or ultrahigh molecular weight polyethylene. The planing protection 52 may be formed of adjacent strips of material 28, which may be arranged with their longitudinal edges 29 in abutment adjacent to each other or overlapping each other. It can also be provided to form the planing protection 52 from a piece of material that extends over the entire protection area 50. Also, the first protective layer 51 may be formed of adjacent strips of material to achieve increased flexibility of the cut protection 41, or be formed from a continuous piece of material. The protective layers 22, 51, 52 and 23 are connected to each other only in its edge region 20 via the seam 3. However, it may be provided that additional seams pass through the protection area 50. Advantageously, the protective layers 51, 52 and 23 are also connected to each other in the protection area 50. The second, outer protective layer 22 is advantageously connected only in its edge region 20 with the other protective layers 51, 52 and 23.

The first protective layer 51 is advantageously at least partially made of a woven, knitted or knitted fabric of a smooth yarn. The smooth, slippery surface 46 may be formed by the surface of this fabric, knit or knit. However, it may be provided that the fabric, knitted or knitted fabric is additionally coated or provided with a paint-containing or plastic-containing paint. The first protective layer 51 may also be formed by a carrier material which is provided with the smooth, slippery surface. When cut protection 41, the first protective layer 51 has no or only little protection against cutting. Due to the smooth, slippery surface 46, however, a tool slides over the surface in both working directions, so that penetration of the tool into the smooth, slippery surface 46 is usually avoided. If a tool nevertheless engages in the first protective layer 51, the teeth of the tool in the third protective layer 52, which is formed from a dense and tensile textile surface, braked. The first protective layer 51 has a thickness 1 which may be comparatively small and advantageously ranges from about 0.2 mm to about 3.0 mm. The third protective layer 52 has a thickness m, which is advantageously greater than the thickness of the first and may be about 0.5 mm to about 5.0 mm, more preferably about 1.0 mm to about 3.0 mm. The total thickness n of the protective region 50 of the cut protection 41 is advantageously from about 2.0 mm to about 15.0 mm, in particular from about 3.0 mm to about 10.0 mm.

Fig. 8 shows an embodiment of a cut protection 61. The cut protection 61 has an outer protective layer 22 which rests on a smooth, slippery surface 26 of a first protective layer 71. The first protective layer 71 rests on a spacer layer 23. The first protective layer 71 is formed by a continuous, flat textile material and not by individual juxtaposed strips of material. The first protective layer 71 comprises a carrier material 69, which advantageously forms a planing protection and on which a smooth layer 31 is arranged. The structure of the individual layers corresponds to that of the FIGS. 4 and 5 described structure. The cut protection 61 has between the two seams 3 in the edge region 20 of the protective layers 20, 71, 23 further seams 63. In the embodiment, two seams 63 are provided. However, a different number of seams 63 may be advantageous. In the exemplary embodiment, the seams 63 extend in the transverse direction of the cut protection 61. Additionally or alternatively, seams can also be provided in the longitudinal direction of the cut protection 61. Adjacent seams 3, 63 have a distance o to each other. The distance o is at least 1.0 cm, in particular at least 3.0 cm. The distance o is selected so that the elasticity of the outer protective layer 22 is sufficient to brake a tool when it engages the cut protection 61 in the working direction. In the exemplary embodiment, the seams 3, 63 connect all the protective layers 22, 71, 23 of the cut protection 61 with each other. However, it may be advantageous to provide, in addition to or as an alternative to the seams 63, seams which connect only the protective layers 71 and 23 with each other.

It can be provided to provide several protective layers as planing protection. Further protective layers between the first protective layer 21, 51, 71 and the spacer layer 23 may be appropriate.

A protective layer is to be understood as an individual material layer which is present in terms of substance and which may be formed integrally from a plurality of components.
