Description

Technical Field

[0001] The invention relates to a grip for a heat-resistant glove, in particular a fire-fighting glove, and to such a glove having at least one grip. Background Art

[0002] Heat-resistant gloves are known from the prior art, for example also having an additional protective plate.

[0003] US 5,822,796 A describes a firefighting glove having segmented, thicker hand and finger pieces. The glove provides the thermal insulation required for firefighting, as well as good dexterity provided by the segments, particularly on the back of the hand.

[0004] Furthermore, US 2007 / 0245453 A1 discloses a firefighting glove having a protective area on the back of the hand made of a semi-rigid material, thereby providing the required degree of flexibility.

[0005] Such gloves, especially firefighting gloves, are usually designed to be relatively sturdy. Because of the need for thermal insulation, they are usually lined with relatively thick linings, padding or insulation materials.

[0006] Problems with such gloves can arise, for example, when it is necessary to grip relatively small objects such as screws or metal pins with the gloves. Due to the protection-oriented properties of gloves, such small objects can usually only be felt or gripped with great difficulty or not at all. Summary of the invention

[0007] The object of the present invention is therefore to provide a heat-resistant or heat-insulating glove, in particular a firefighter's glove, which, in addition to temperature resistance, also has an improved sense of touch or the ability to grip relatively small objects.

[0008] The functionality of such gloves, namely in particular the ability to withstand temperature and high mechanical stress, is a prerequisite for the wearer to be able to use the gloves accordingly. The temperature resistance of the components and their thermal insulation work together to provide thermal protection for the hands.

[0009] The ability to withstand high mechanical stresses allows, on the one hand, improved protection for the wearer's hands. On the other hand, this expands the range of applications and gives the glove tool-like functions. For example, it can also be used as a striking tool.

[0010] The application range of such heat-resistant gloves ranges from motorcycle gloves to tactical gloves for military special forces to special firefighting gloves. Depending on the specific situation, thermal insulation or mechanical strength is relevant in different ranges.

[0011] Temperature resistance and thermal insulation are usually ensured by a coordinated structure of different materials, which are temperature-resistant in themselves and can act as thermal insulation when they interact with each other. However, in the simplest case, the basic structure of the glove can also be made of a single temperature-resistant material, which only provides short-term thermal protection through the heat capacity of the other homogeneous materials. However, layered structures consisting of different materials (e.g. lining fabric, membrane insert and / or outer layer material) which interact with each other to improve the protection of the hand from thermal loads are advantageous.

[0012] Due to the high protection requirements placed on such gloves and their resulting properties, it has hitherto been impossible or only partially difficult to pick up delicate objects, i.e. relatively small objects (especially compared to the size of the glove or one of its finger pieces), such as screws, narrow pins, carabiners, cables, ropes etc.

[0013] The invention relates to a gripping piece, which is designed to be connected to the finger end region of a heat-resistant glove and to grip an object with the glove. The gripping piece has a support surface defined by at least one first edge and a second edge, wherein the first edge has a defined edge contour, which is adapted to the contour of the finger end region, in particular the fingertip, of the glove finger. In addition, a connection region is provided for fixing the gripping piece to the finger end region. The gripping piece also has a retaining piece connected to the support surface and protruding in a first protruding direction perpendicular to the support surface, wherein the retaining piece has a longitudinal extension perpendicular to the first protruding direction.

[0014] Therefore, according to the present invention, a grip is accordingly proposed, which is designed to be combined with, in particular connected to, the finger end area of ​​a heat-resistant glove. The protruding retainer provides a simple way to grasp the above-mentioned small objects while still retaining other functional properties of the glove, such as temperature resistance.

[0015] In one embodiment, the longitudinal extension of the retainer in a direction perpendicular to the first projection can correspond to the edge profile of the first edge. Therefore, the retainer can be formed into the shape of the first edge, or extend along the edge, for example, also extend at a distance from the edge.

[0016] In one embodiment, the edge profile of the first edge may be at least partially curved or rounded and adapted to the profile of the fingertip of the glove finger.

[0017] By correspondingly shaping the edge and / or the holder, the shape of the holder can be further designed in a particularly advantageous manner in order to improve the tactility and grip of the object.

[0018] In one embodiment, the thickness of the retaining element can decrease in a direction perpendicular to its extension in the projection direction. In particular, the retaining element accordingly has a shape that tapers towards its free end, in particular in terms of thickness. The thickness is in particular a dimension in a direction perpendicular to the first projection direction and perpendicular to the longitudinal extension of the retaining element. Alternatively, the contour of the retaining element can also be curved in the projection direction. The retaining element can in particular be formed in the shape of a shovel.

[0019] The length of the second edge can in particular be at least twice as long as the length of the retaining element over its longitudinal extension.

[0020] By means of such a shape of the holder, gripping of a thin metal pin, for example on a flat surface, can be further simplified. The holder is thus shaped in such a way that it is easy to slide the pin onto the holder or to pry the pin. In particular, by means of the tapering shape, it is easier to slide the holder under the pin.

[0021] When grasping an object, the position of the pin in the retaining member can be deepened by the reaction force of the opposing finger piece of the glove (for example, the reaction force of the index finger when the gripping piece is set on the thumb of the glove), and the pin can be stably lifted with the glove.

[0022] In one embodiment, the second edge may be straight and the first edge may be curved within a first angle of 180°, in particular wherein the support surface may at least partially have a semi-elliptical, semi-circular, parabolic or hyperbolic shape. Such a shape may provide a customized application of the gripper to the fingertip of the glove finger.

[0023] According to one embodiment, the retaining element may be arranged in a first portion of the support surface, wherein the first portion is defined by a first axis defined by the contour of the second edge and a second axis intersecting a midpoint of the second edge, and the first axis and the second axis enclose a first angle of at most 90°.

[0024] In one embodiment, the retaining surface of the retaining element may face the second edge and define a corresponding central retaining axis of the retaining element. The retaining axis preferably extends through a midpoint of the retaining surface.

[0025] In particular, the extension direction of the retaining axis and the second edge may enclose an angle in the range of 30° to 60°, in particular an angle of 45°.

[0026] Thus, the holding element can be arranged on the side of the gripping element. This makes it easy to place the holding element on the base from which the object is to be lifted during gripping. Thus, this further simplifies the gripping of the object.

[0027] In particular, the shape of the retaining surface may correspond to a portion of the side surface of a pyramid with a circular base, ie have a curvature both in its extension direction and in its projection direction.

[0028] In one embodiment, the gripping member may have a clamping member connected to the supporting surface and protruding in a second protruding direction perpendicular to the supporting surface, wherein the second protruding direction is opposite to the first protruding direction.

[0029] In particular, the clamping element can be arranged opposite the retaining element with respect to the support surface and can be configured to secure the gripping element to the finger end region of the glove.

[0030] The clamping piece enables a more stable connection of the gripping piece to the finger piece of the glove. For example, the clamping piece can be additionally sewn to the glove material and / or connected to both sides of the glove material. The clamping piece can also provide a stable and uniform transition between the gripping piece and the glove.

[0031] Alternatively or additionally, the clamping element can be configured and arranged such that its shape and / or spatial dimensions provide an increase in the contact surface of the gripping element on the base when gripping an object. This simplifies the positioning of the holding element relative to the object to be gripped.

[0032] In one embodiment, the support surface can have an anti-slip, in particular friction-increasing surface structure at its top. The top is understood to be that side of the support surface which is not located on the glove or is not intended to be located on the glove. By means of the surface structure, objects can be gripped or held more reliably. The surface structure can provide increased roughness and / or waviness. The surface structure can be formed, for example, by ribs, bumps, corrugations, etc.

[0033] The present invention also relates to a heat-resistant glove, in particular a fire-fighting glove, which has a fire-resistant outer layer material and at least one gripping element as described above.

[0034] The gripping member can be particularly arranged on a thumb member, an index finger member, a middle finger member, a ring finger member or a little finger member (a finger member of a little finger) of a glove. In particular, the gripping member can be arranged on a finger end region, in particular a fingertip, of a corresponding finger member.

[0035] In one embodiment, the gripping member may be sewn to the outside of the outer layer material, bonded to the outside of the outer layer material and / or welded to the outside of the outer layer material. In particular, the glove may have a seam connecting the connecting portion of the gripping member to the fire-resistant outer layer material. Thus, the seam may pierce the connecting portion.

[0036] In one embodiment, the gripping element may be at least partially arranged below the fire-resistant outer layer material, in particular between the outer layer material and the lining, or at least partially integrated into the outer layer material. In particular, at least the retaining element may not be arranged below the outer layer material. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The gripping element and the heat-resistant glove according to the invention will be described in more detail below with reference to the embodiments schematically shown in the accompanying drawings, but this is merely exemplary. Identical parts are indicated by the same reference numerals in the drawings. The described embodiments are generally not drawn to scale and should not be understood as limiting.

[0038] Specifically,

[0039] Figure 1 An embodiment of a gripping member according to the present invention is shown;

[0040] Figure 2 Shows Figure 1 A cross-sectional view of a gripping member according to the present invention;

[0041] Figure 3a to Figure 3b shows an embodiment of a heat-resistant glove according to the present invention; and

[0042] Figure 4 Another embodiment of the heat-resistant glove according to the present invention is shown. DETAILED DESCRIPTION

[0043] Figure 1 An embodiment of a gripping element 1 according to the invention is shown in a top view. The gripping element 1 is configured to be connected to a glove, in particular to a heat-resistant glove (e.g. a fire-fighting glove). To this end, the gripping element 1 can be connected, for example, to a thumb piece of such a glove. Preferably, the gripping element 1 is arranged at the end region of a finger or thumb, in particular at the fingertip.

[0044] The gripping element 1 has a support surface 2. The support surface 2 is suitable for connection with a glove, in particular with a corresponding glove or a finger piece of a glove (such as a thumb or index finger) in terms of spatial extension and / or shape. The support surface is defined by a first edge 3 and a second edge 4.

[0045] The contour of the first edge 3 is curved. In the embodiment shown, the edge contour approximately describes a portion of an ellipse. However, the edge contour of the first edge 1 can have alternative shapes, such as a partial parabola, hyperbola or semicircle. In particular, the edge contour of the first edge 1 is adapted to the shape of the end region of the glove finger. The curvature of the edge 3 here extends in particular within a first angular range 8 of 180°.

[0046] The gripping element 1 also has a connection region 5. The connection region 5 serves to provide a connection or fixation of the gripping element 1 to the glove. The connection region 5 is formed here as a sewn edge. The gripping element 1 can be sewn to the glove and thus connected to the glove via the sewn edge 5. For example, the sewing is performed with the outer material of the glove, for example with a woven or woven fabric.

[0047] In an alternative embodiment (not shown), the connection area may be provided by at least a portion of the bottom surface of the support surface 2 lying on the glove. The connection to the glove may then be achieved, for example, by bonding or (polymer-based) cross-linking.

[0048] The grip 1 also has a retaining element 6. The retaining element 6 is connected to the support surface 2, protrudes in a first protrusion direction 7 perpendicular to the support surface 2, and in particular extends along a portion of the first edge 3, for example parallel to the edge 3 or on the edge 3. The connection between the retaining element 6 and the support surface 2 is provided in particular by gluing, welding or by integral production of the two parts.

[0049] The holder 6 may be formed in particular in the shape of a shovel. Thus, at least the contour of the inner side surface of the holder 6 may be curved in the protruding direction 7.

[0050] The holder 6 is arranged in the first portion 9 of the support surface 2. The first portion 9 is defined or delimited by a first axis 10 corresponding to the contour of the second edge 4 and a second axis 11 which intersects the middle point of the second edge 4 (in terms of its length). The first axis 10 and the second axis 11 enclose a first angle 12 of 90°. The holder 6 is therefore not arranged centrally but laterally relative to a central axis corresponding to the second axis 11 in the embodiment shown.

[0051] The retaining element 6 has a retaining surface 13 facing the second edge 4. The surface 13 thus defines the position of a corresponding central retaining axis 14. The retaining axis 14 extends in particular through the midpoint of the retaining surface 13. The retaining element 6 is oriented such that the retaining axis 14 intersects the first axis 10 (corresponding to the extension direction of the second edge) at an angle of 45°.

[0052] In the embodiment shown, the retaining element 6 is designed such that its outer side 15 opposite the retaining surface 13 has a uniform transition to the first edge 3. Alternatively, the retaining element 6 can be arranged offset from the edge 3.

[0053] Figure 2 Shows Figure 1 FIG. 1 shows a view of a grip 1 according to the invention in cross section (section parallel to the second axis 11 ).

[0054] As shown, the gripping element 1 has a clamping element 16 on its bottom side. The clamping element 16 extends in a second protrusion direction 17 perpendicular to the support surface 2, wherein the second protrusion direction 17 is opposite to the first protrusion direction 7. The clamping element 16 provides a firm and reliable fixation of the gripping element 1 on the finger end area of ​​the glove. In order to achieve such a reliable connection with the glove, a part of the outer material of the glove finger can be sewn to the clamping element 16 on both sides of the clamping element 16. By using this additional fixation of the clamping element 16, the gripping element 1 can be clamped together with the outer material of the glove.

[0055] The support surface 2 is designed in two layers in this embodiment. For example, the two layers 2a and 2b can be connected to each other by bonding or welding and thus jointly provide the support surface 2. Alternatively, the support surface 2 can be manufactured so that the two layers 2a, 2b are connected to each other by a manufacturing process, for example by a manufacturing-side cross-linking process in plastic processing, and can be considered as one piece. In an alternative embodiment, the support surface 2 is formed by a single material layer.

[0056] The layer 2a has in particular a surface structure 18 which provides an improved (increased) surface roughness and / or waviness. This can provide an anti-slip or anti-slip and / or friction-increasing effect on the top side of the grip 1. Such a structure 18 is very advantageous for gripping and / or holding relatively small objects, since a greater holding force is achieved by a relatively greater surface roughness or waviness (compared to a smooth surface).

[0057] The layer 2b is connected to the clamping element 16, in particular is formed integrally therewith. The retaining element 6 may be connected only to the layer 2a, or to both the layer 2a and the layer 2b.

[0058] Figure 3a and Figure 3b A possible embodiment of a heat-resistant glove 20 according to the present invention is shown. In the embodiment, the glove 20 is designed in a five-finger form, wherein it can also be optionally designed in a three-finger form or a mitten form. The glove 20 consists of a lining 22, which has one or more layers and includes a heat-resistant outer layer material 21, which is in particular assembled or formed from a plurality of material blanks.

[0059] The material constituting the outer layer 21 (outer layer material) or other layers of the lining 22 may be selected, for example, from the following group: leather material, textile material or plastic material. In addition, one or more layers of the lining 22 may be formed by functional layers, which fulfill specific purposes. For example, a liquid-tight functional layer, in particular a semipermeable membrane or film, may be provided in the lining 22.

[0060] The outer material 21 and / or one or more layers of the lining 22 and / or the lining material or the insulating material of the glove 20 may be composed, for example, of the following raw materials or mixtures thereof:

[0061] - (aromatic) polyamides with a high melting point, in particular meta- or para-aramids, such as Kermel, Nomex, Kevlar, Technora, PBI, Apyeil, Teijinconex or Twaron,

[0062] - crystalline polymers, in particular PBO fibers such as Zylon or Vectran,

[0063] - Adhesive FR, such as Lenzing FR,

[0064] - Fiberglass,

[0065] - Flame-retardant leather or corresponding textiles or flexible substrates, for example with a coating made of silicone, polyurethane or silicon carbon.

[0066] Figure 3a The underside of the glove 20, ie, the palm side, is shown. Figure 3b The top side of the glove 20, ie, the back of the hand side, is shown.

[0067] The glove 20 has, on its palm side, a grip 1 according to the invention, which has a retaining element 6. The grip 1 is arranged on the index finger 23 of the glove 20 in the fingertip region.

[0068] The holder 6 is oriented so that the outer side 15 of the holder 6 faces away from the glove 20. With this arrangement, the grip 1 or holder 6 can be used to provide the ability to easily grip small objects, such as screws or pins, with a relatively sturdy glove.

[0069] An object can be successfully grasped or picked up by merging the finger tip area of ​​the index finger 23 provided with the grip 1 with the thumb 24 , in particular with the finger tip area of ​​the thumb 24 , during a grasping movement, with the object being located between the grip 1 and the thumb 24 .

[0070] When gripping an object, for example, on a flat base, the holding element 6 can be guided or slid under the object, wherein the object is located on the holding element 6 by counter-holding with the thumb 24. The object can then be held and picked up by clamping or pressing between the gripping element 1 and the thumb 24.

[0071] The optional non-slip surface structure of the grip 1 helps to securely hold the object and prevent it from slipping.

[0072] Using typical firefighting gloves without the gripping aid 1 according to the invention, picking up, for example, a pin is only very difficult or not possible at all.

[0073] Figure 4 Another possible embodiment of a heat-resistant glove 20 according to the invention is shown. The palm side of the glove 20 is shown. The glove 20 has a grip 1 according to the invention on its thumb piece 24.

[0074] The grip 1 has a retaining element 6 and a surface structure 18 which prevents objects from slipping off. The surface structure 18 can be provided, for example, by a plurality of transverse ribs, by means of blades or by a wave-shaped surface profile.

[0075] The grip piece 1 also has a connection area 5, which here extends along the edge, in particular along the first edge and the second edge, of the grip piece 1. The grip piece 1 is sewn to the base glove 20 in the connection area 5, i.e. around the periphery of the grip piece 1. The connection area 5 and the glove 20 therefore have a corresponding seam.

[0076] This embodiment can be used similar to Figure 3a and Figure 3b Small objects are grasped in the same manner as in the embodiment of FIG. 1 , except that the reverse holding is performed using the index or middle finger member 23 , 24 and the object then interacts with the holding member 6 .

[0077] According to an alternative embodiment, the grip 1 can be sewn to at least one layer of the outer material or the decorative material or partially covered by it. The retaining element here in particular remains exposed. The grip 1 can be at least partially covered by a lining or insert layer, for example by a semipermeable membrane. In an alternative embodiment, the grip 1 can also be partially integrated between multiple layers of the outer material or between the palm-side liners.

[0078] The heat-resistant glove 20 with a grip according to the present invention, in particular a firefighting glove, in particular complies with the European firefighting standard EN 659 as well as the Australian firefighting standard AS2161.10 and the American firefighting standard NFPA 1971. In addition, the glove 20 according to the present invention also complies with the rescue standard NFPA 1951 and other globally known standards, such as EN 407 (thermal risk), heat and fire resistance standards, etc.

[0079] The glove 20 according to the invention thus meets the requirements for firefighting gloves, wherein the post-burn time is less than 2 seconds and the smoldering time is less than 5 seconds for a burning time between 3 and 15 seconds. The distance between the flame tip and the lowest point of the burning glove is between 10 and 30 mm. The glove can burn vertically or horizontally. The material used in the glove neither drips nor melts during burning and / or the burning site does not penetrate.

[0080] Furthermore, when the flame comes into contact with the glove, the time period for the temperature to rise by 24°C in the unburned area is less than 13 seconds.

[0081] At a heat flux of 40kW / m 2 The material removed from the back of the hand shall be exposed to a 24°C rise in temperature for a period of not less than 11 seconds in the unburned area. At a contact temperature of at least 250°C, the material of the palm structure shall withstand the heat for at least 10 seconds before burning. In addition, the lining material shall neither melt, drip, nor ignite at a minimum temperature of 180°C. At a temperature of at least 180°C for 5 minutes, the shrinkage of the glove shall not exceed 5%.

[0082] It should be understood that the figures shown only schematically represent possible embodiments. The different methods can also be combined with each other and with devices and methods of the prior art.
