Description

[0055] The invention is described in more detail below by means of a preferred example embodiment and with reference to the accompanying drawings, in which:

[0056] FIG. 1 shows an isometric representation of an inside of an inner glove surface of an arc fault protective glove according to the invention;

[0057] FIG. 2 shows an isometric representation of an inside of a glove back of the arc fault protective glove according to the invention;

[0058] FIG. 3 shows an isometric representation of an outside of the inner glove surface of the arc fault protective glove according to the invention; and

[0059] FIG. 4 shows an isometric representation of an outside of the glove back of the arc fault protective glove according to the invention.

[0060] FIGS. 1 to 4 show the structure of an arc fault protective glove 10, FIGS. 1 and 2 explaining the structure of the inner sides, whereas FIGS. 3 and 4 show the structure of the outer sides of the arc fault protective glove 10.

[0061] The arc fault protective glove 10 shown in FIGS. 1 to 4 basically consists of a hand area 12 and a forearm area 14. The arc fault protective glove 10 thus serves both to protect the hand of the wearer and also to protect the forearm.

[0062] The hand area 12 corresponds to the negative of a human hand and is designed such that it can accommodate and completely surround a human hand. For this purpose, the hand area 12 includes a total of five finger elements 16 which can fully accommodate the fingers of a hand when worn. The forearm area 14 is configured so as to fully enclose a forearm in the circumferential direction when worn.

[0063] To ensure the correct fit of the arc fault protective glove 10, an elastic band 18 is additionally provided on the inner side at the transition from the forearm area 14 to the hand area 12, i.e. only in the area of an inner glove surface 20 which is shown in FIG. 1.

[0064] The elastic band 18 constricts the arc fault protective glove 10 in the area of the wrist of the wearer, i.e. between the forearm area 14 and the hand area 12. The elastic band 18 is in particular sewn to the hand area 12 and/or the forearm area 14. The seam is preferably formed by an aramid thread.

[0065] FIG. 1 shows the structure of an inner side 22 of the inner glove surface 20 of the arc fault protective glove 10.

[0066] In other words, the inner side 22 of the arc fault protective glove 10 shown in FIG. 1 is turned to the outside for a better overview, or the arc fault protective glove 10 is turned inside out.

[0067] The inner side 22 of the hand area 12 is formed by a first layer 24. The first layer 24 is designed so as to form the inner side of the finger elements 16, the inner side of a palm section 26 and the inner side of the forearm area 14. In this respect, the first layer 24 corresponds to a base layer of the arc fault protective glove 10 which extends over the entire length of the arc fault protective glove 10.

[0068] The first layer 24 is made of a leather, in particular a genuine leather, particularly preferably a cowhide leather.

[0069] The palm section 26 only covers the palm of a hand when worn. The palm section 26 is therefore provided between the finger elements 16 and the forearm area 14.

[0070] The palm section 26 has an edge area 28 which is provided with a seam 30 designed as a single seam. The single seam 30 in particular comprises an aramid thread.

[0071] The seam 30 is intended to sew the first layer 24 to an additional second layer 32 which is provided only in the palm section 26 and thus reinforces the first layer 24 in the region of the palm section 26, as can be seen from FIG. 3, which shows the outer side of the inner glove surface 20 of the arc fault protective glove 10. The seam 30 runs in the edge area 28 of the second layer 32, as can be seen in FIG. 3.

[0072] Basically, the first layer 24 and the second layer 32 each have a thickness in the range from 0.3 to 2.0 mm, preferably from 0.5 to 1.5 mm, particularly preferably from 1.0 to 1.2 mm.

[0073] A thumb section 34 which is connected, in particular sewn to the palm section 26 is provided adjacent to the palm section 26.

[0074] The thumb section 34 is designed so as to fully cover the back of the thumb when worn. In contrast thereto, the inner side of the thumb is covered by the first layer 24.

[0075] The thumb section 34 is formed from three layers arranged one above the other.

[0076] The three layers consist of an inner thumb lining 36 (first layer), which is clearly visible in FIG. 1 and forms part of the inner side 22 of the arc fault protective glove 10.

[0077] In addition, the three-layer thumb section 34 comprises a backing layer (second layernot shown here), which is bonded to the inner thumb lining 36.

[0078] Furthermore, the palm section 26 has a flame protection layer 38 (third layersee FIG. 3), which forms part of an outer side 40 of the arc fault protective glove 10 and is arranged on a side of the backing layer which faces away from the inner thumb lining 36.

[0079] The inner thumb lining 36 in particular consists of an aramid fabric which is also referred to as Kevlar fabric.

[0080] The backing layer in particularly consists of a chloroprene rubber, which is also referred to as neoprene.

[0081] The flame protection layer 38 consists of a foamed chloroprene rubber which is optionally provided with a special additive.

[0082] The additive may be carbon, in particular in the form of carbon black.

[0083] The flame protection layer 38 can be formed of a material, in particular a neoprene, which is a self-contained, extruded and vulcanized cellular rubber to which carbon black or pure carbon is added.

[0084] The inner thumb lining 36 has an edge area in which a double seam 42 is provided. The double seam 42 connects the thumb section 34, in particular the inner thumb lining 36 and/or the backing layer, to the first layer 24 and/or the second layer 32 (in the area of the palm section 26). The corresponding double seam 42 runs in a transition area between the different materials.

[0085] The inner thumb lining 36 can thus be both bonded and sewn to the backing layer.

[0086] The thumb section 34 further merges into an intermediate section 44 which is provided in the forearm area 14 described at the beginning. The intermediate section 44 is also sewn to the first layer 24 by means of the double seam 42, in particular in a transition area.

[0087] At the end opposite the hand area, i.e. the open end, the forearm area 14 ends with a hem 46 which has a single seam 48, provided as a zig-zag seam.

[0088] The hem 46 extends completely in the circumferential direction and forms the opening for inserting the hand into the arc fault protective glove 10.

[0089] Like the thumb section 34, the intermediate section 44 is formed from the aforementioned three layers. This means that the intermediate section 44 has an inner lining 50 which forms part of the inner side 22 of the arc fault protective glove 10. The inner lining 50 in particular comprises an aramid fabric.

[0090] The inner lining 50 is arranged on a backing layer (not shown here), in particular bonded thereto, the backing layer consisting of a chloroprene rubber.

[0091] On a side of the backing layer which faces away from the inner lining 50, a flame protection layer 52 is provided which forms part of the outer side 40 of the arc fault protective glove 10. The flame protection layer 52 in particular consists of a foamed chloroprene rubber which is optionally provided with a special additive.

[0092] In principle, the seams are formed by aramid threads, i.e. Kevlar threads.

[0093] FIG. 2 shows the inner side 22 of a glove back 54 of the arc fault protective glove 10.

[0094] The glove back 54 in particular covers the forearm area 14 and the hand area 12. In addition, the glove back 54 extends from the hem 46 to the ends of finger elements 16.

[0095] The glove back 54 has the same three-layer structure as the thumb section 34 and the intermediate section 44.

[0096] The glove back 54 thus has an inner lining 56 on the back of the hand, which faces the back of the hand when worn, i.e. the inner side 22 of the arc fault protective glove 10.

[0097] The inner lining 56 on the back of the hand in particular consists of an aramid fabric.

[0098] The inner lining 56 on the back of the hand is bonded to a backing layer (not shown here). In particular, the inner lining 56 on the back of the hand is sewn in an edge area to the backing layer and/or to the first layer 24 of the arc fault protective glove 10 which serves as a base layer using a double seam 42. The double seam 42 is formed by an aramid thread.

[0099] The backing layer is made of a chloroprene rubber.

[0100] Furthermore, the glove back 54 has a flame protection layer 58 which is provided on a side of the backing layer which faces away from the inner lining 56 on the back of the hand, the flame protection layer 58 being in particular made of a foamed chloroprene rubber which is optionally provided with a special additive.

[0101] As already explained, the glove back 54 is sewn to the first layer 24 which forms finger side sections of the arc fault protective glove 10. The first layer 24 is preferably sewn to the glove back 54 by a single seam which is in particular formed by an aramid thread.

[0102] FIG. 3 shows the outer side 40 of the inner glove surface 20 of the arc fault protective glove 10.

[0103] FIG. 3 basically shows the same components and features as FIGS. 1 and 2, and in this respect, reference is made to the description of FIGS. 1 and 2.

[0104] As is clearly visible in FIG. 3, the inner glove surface 20 of the arc fault protective glove 10 has the additional second layer 32 which is assigned to the palm section 26. The first layer 24 of the arc fault protective glove 10 serving as a base layer is therefore accordingly reinforced in the area of the palm section 26.

[0105] The second layer 32 is in particular sewn to the underlying first layer 24 (as seen from the outside) by means of a single seam 30 in an edge area 28 of the palm section 26.

[0106] In particular, the seams have been produced using an aramid thread.

[0107] Furthermore, the seams are placed on the inside so that they are not visible on the outer side of an arc fault protective glove 10.

[0108] The second layer 32 is made of a leather, preferably a genuine leather, particularly preferably a cowhide leather.

[0109] In this respect, both the first layer 24 and the second layer 32 are made of the same material, namely a leather, for example a genuine leather such as a cowhide leather.

[0110] The leather may be provided with a flame protection coating, the leather being in particular siliconized to form the flame protection coating.

[0111] In other words, the second layer 32 covers the palm of a wearer of the arc fault protective glove 10, while the inner surfaces of the finger elements 16, in particular of the thumb, are only covered by the first layer 24.

[0112] In this way, the protection against the thermal effects of an arc fault can be increased without restricting the freedom of movement when wearing the arc fault protective glove 10. Due to the arrangement of the second layer 32 in the area of the palm section 26, the finger elements 16 in particular remain movable.

[0113] As in FIG. 3, the arc fault protective glove 10 is turned right side out, the outermost layer of the three-layer structure described above is now visible on the thumb section 34. It is formed by a flame protection layer 38. The flame protection layer 38 extends from the end of the finger element 16 intended for the thumb, up to the intermediate section 44 which also has a three-layer structure, i.e. also the flame protection layer 52, which extends up to the hem 46. Therefore, a section of the forearm area 14 is also covered by the flame protection layer 52. This section also has the three-layer structure already described above.

[0114] In principle, the thumb section 34 and the intermediate section 44 can together form a section, as can be seen in particular from FIG. 3. The two sections 34, 44 are overlaid by the elastic band 18 only on the inside and are thus functionally separated from each other. However, the elastic band 18 is attached to the inner first layer of the sections 34, 44, i.e. the inner lining 36, 50.

[0115] FIG. 4 shows the outer side 40 of the glove back 54 of the arc fault protective glove 10.

[0116] On the outer side 40, the glove back 54 consists of the flame protection layer 58. The flame protection layer 58 of the glove back 54 extends from the ends of finger elements 16 up to the hem 46 of the forearm area 14.
