Description

  The present invention relates to a glove palm reinforcement structure and a glove, and more particularly, a glove used under severe conditions, such as a glove used by a rescue team in rescue of a helicopter. About.

  In rescue teams such as fire departments, self-defense forces, Japan Coast Guard, and police in each local government, rescue operations such as rescue from water accidents and rescue from mountain disasters are not possible by human power. Helicopter rescue activities cover a wide range, including emergency transport of victims, cautionary command support in the event of disaster or transport of materials, materials, and personnel, but in particular, hoist rescue that uses hoists to lift and rescue victims etc. This is a rescue method unique to helicopter rescue.

  In this hoist rescue, as shown in FIG. 8 (a), the rescuer guides the lifting / lowering operation of the wire cable b of the hoist with one hand (right hand in the case of illustration) or moves the wire cable b at the stop position. While supporting, the other hand (not shown) performs the on / off operation of the hoist drive motor and the operation speed adjustment operation.

  By the way, the hand a on the side that supports the wire cable b of the hoist is usually operated by wearing the reinforcing gloves d on the normal leather working gloves c. This is because the work gloves c have insufficient strength and poor heat insulation, and are quickly worn and damaged by frictional heat with the wire cable b when directly supporting the wire cable b of the hoist. This is because the work gloves c alone cannot withstand actual use.

  As shown in FIG. 8 (b), the reinforcing glove d is made of thin leather having a thickness of about 1 mm, and the wrist part is opened, as well as the normal work glove c, and 5 fingers This is an overglove type that is formed in a bag shape with a cut-opened fingertip part, and is structured to be worn over the work gloves c as described above. In this way, by repeatedly wearing the reinforcing gloves d on the normal working gloves c, the disadvantages of the working gloves c can be compensated.

  However, since the conventional reinforcing glove d is made of the same thin leather as the normal working glove c, although it is excellent in workability, it is still insufficient in strength, and the hoist with the wire cable b of the hoist. Although the frictional heat quickly wears out and breaks, and the life of the working glove c can be extended, the reinforcing glove d itself becomes substantially unusable by one or two rescue operations. Therefore, there is a problem that the durability is poor and the lifetime is remarkably short, which is very uneconomical, and further improvement in this respect has been demanded.

  As far as the present applicant knows, there is no patent document that discloses this prior art.

  The present invention has been made in view of such conventional problems, and the object of the present invention is, in particular, wear and damage in gloves used under severe conditions, such as gloves used in rescue operations by helicopters.

Configured to work.

The glove palm reinforcement technique of the present invention was born as a result of various test and research efforts by the present inventors.
That is, the present inventor, particularly in gloves used for lifesaving by rescue teams, does not impair wearing workability that is originally required as a glove that is the most familiar work tool that should save the life. We have sought a glove palm reinforcement structure that has a long life even when used under conditions.

  And this inventor overturned the common knowledge about the leather material used for conventional work gloves, thick leather (though it is sufficient in strength, but hard and inflexible and difficult to bend, wearing It was not suitable as a material for working gloves because it was uncomfortable and the workability was extremely bad, so we focused on the possibility of using it as a reinforcing material for the palm part of gloves.

  In other words, by taking advantage of the thick leather (having sufficient strength) and repeating various researches and experiments to overcome the poor wearing workability that is its disadvantage, by devising its sewing structure It was discovered that the disadvantages of thick leather could be eliminated, and after further trial and error by the inventor, the present invention was completed.

  That is, according to the present invention, a main body reinforcing piece made of thick leather having an outer contour corresponding to the contour shape of the palm portion of the glove main body, and a bent portion of the main body reinforcing piece are fixedly supported. And a bending portion of the main body reinforcing piece is set in a line shape along a side edge of the palm portion of the glove body, and the three-dimensional forming piece is In addition, a part of the outer contour edge is a forming support portion that supports and fixes the bent portion of the main body reinforcing piece, and the contour shape of the forming support portion follows the shape of the palm portion of the glove body. The main body reinforcing piece and the three-dimensionally formed piece are integrated with the palm portion of the glove main body in a state where the forming support portion of the three-dimensional formed piece is positioned and polymerized on the back surface of the bent portion of the main body reinforcing piece. The above-mentioned main body Strong piece can be realized sewing structure along a curved three-dimensional shape of the palm portion of the glove body.

  As a result, sufficient strength, which is an advantage of thick leather, is utilized, while the disadvantage of wearing workability, which is a disadvantage, is also eliminated. Even when used under severe conditions, it has become possible to provide a work glove with a long life without impairing the wear workability, which is a function.

  That is, since the main body reinforcing piece has a sewing structure along the three-dimensional shape of the palm portion of the glove main body, the glove main body has a thick leather main reinforcing piece that is hard and less flexible. Despite being used, the glove body can be deformed in accordance with the natural hand movement from the beginning of wearing, and good wearing workability can be ensured.

  In addition, since the formation support portion of the three-dimensionally formed piece is provided with a bending groove for forming a bending operation portion of the main body reinforcing piece, the bending operation portion of the main body reinforcing piece is made constant so that the operation of the glove is more stable. And workability are ensured.

  In particular, in a glove used for helicopter rescue, the concave groove formed in the bending action part functions as a sliding support part of the rescue wire, that is, the wire cable of the hoist, and the wire cable slides through. This makes it possible to avoid the problem of the danger of being difficult to use because the location of the cable is stably obtained, the wire cable is violated in the palm, the support is not stable, and it is difficult to use.

  Similarly, for example, in a glove used for wheelchair operation, the concave groove formed in the bending operation portion functions as a wheel operation portion of the wheelchair, and the wheel operation location can be stably obtained. The risk of the user making a mistake in operation is effectively avoided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 and FIG. 2 show a glove according to the present invention. Specifically, the glove 1 is a helicopter rescue as shown in FIG. 6 by rescue teams such as fire departments, self-defense forces, Japan Coast Guard or police of each local government. The glove body 3 is provided with a palm reinforcing structure A as a main component at the palm portion of the glove body 3.

  The glove body 3 is made of thin artificial leather having an over glove type having a shape and size that is attached to the outside of the work glove 2 attached to the hand H. The fingertip portion is formed in a bag shape having a cut opening. Moreover, as shown in FIG. 5, the wrist part of the glove body 3 has a structure that can be tightened and released by a fixing belt 4 provided with a hook-and-loop fastener 4a.

  The palm reinforcement structure A is a reinforcement structure for reinforcing the palm portion of the glove body 3, and a palm reinforcement member 5 made of leather is integrally fixed to the palm portion of the glove body 3. In the illustrated embodiment, when the glove body 3 is sewn, the palm reinforcing member 5 is sewn to the glove body 3 at the same time.

  The palm reinforcing member 5 includes a main body reinforcing piece 10 and a three-dimensionally formed piece 11. In the illustrated embodiment, as shown in FIGS. 3 and 4, the main body reinforcing piece 10 and the main body are provided. The reinforcing piece 10 is composed of a pair of left and right three-dimensionally formed pieces 11 a and 11 b that are integrally fixed to the left and right sides of the reinforcing piece 10.

  The main body reinforcing piece 10 is made of thick leather having an outer contour corresponding to the contour shape of the palm portion of the glove main body 3, and the thickness dimension is set to 1.6 to 2.3 mm, more preferably 1. .8 to 2.0 mm. The thickness dimension of the main body reinforcing piece 10 is set in such a range. If the thickness dimension is smaller than 1.6 mm (thin), a desired strength cannot be obtained, while the thickness dimension is 2 If it is larger than 3 mm (thick), it is sufficient in strength, but it is hard, poor in flexibility and difficult to bend, and is not suitable for the constituent material of gloves.

  By the way, as mentioned above, the leather material of a normal working glove is a thin one with a thickness of about 1 mm, and a thick leather with a thickness of 1.6 to 2.3 mm has been conventionally used. It is used only for special purpose gloves such as baseball glove that require particularly high strength but does not require fine movement like normal manual work, and helicopter rescue like this embodiment. It was impossible to use gloves that require workability, such as gloves used in

  Further, as a tanning treatment of the leather material constituting the main body reinforcing piece 10, tannin tanning using tannin such as plant tannin or synthetic tannin as a tanning agent, or tannin such as plant tannin or synthetic tannin as a tanning agent Mixing tanning using a mixture of a basic chromium sulfate salt is suitably performed. By appropriately devising the mixing ratio of tannin and basic chromium sulfate salt in the tanning agent, it is possible to obtain optimal hardness, heat resistance, etc. according to the purpose.

  The specific outer peripheral contour shape of the main body reinforcing piece 10 corresponds to the contour shape of the palm portion of the glove main body 3 as shown in FIGS. 1 and 4, and the first finger (thumb) to the fifth finger (little finger). Finger portions 10a to 10e that are coated and polymerized are respectively provided on the palm side of the base portion. Further, the finger parts 10b to 10e corresponding to the base parts of the second finger to the fifth finger are provided with notches 12, 12,... For ensuring the ease of bending of the finger parts. In FIG. 4, reference numeral 13 denotes a notch that enables the main body reinforcing piece 10 to form a three-dimensional curve.

  The three-dimensionally formed pieces 11a and 11b are made of thick leather that three-dimensionally curves and forms the main body reinforcing piece 10 by fixing and supporting the bent portion of the main body reinforcing piece 10, and the thickness dimension and tanning treatment thereof are The same as the main body reinforcing piece 10.

  As shown in FIGS. 3 and 4, the compatible body forming pieces 11 a and 11 b are folded when part of the outer contour edges 15 a and 15 b are sewn to the glove body 3 of the main body reinforcing piece 10. It is the formation support part which supports and fixes the curved part 20 (20a, 20b).

  Moreover, the bending part 20 (20a, 20b) of the said main body reinforcement piece 10 is set to the linear form along the right-and-left side edge part 3a, 3b of the palm part of the said glove body 3, respectively, as shown in FIG. The

The formation support portions 15 a and 15 b of the three-dimensionally formed pieces 11 a and 11 b have curved shapes that follow the shape of the palm portion designed based on the ergonomics of the glove body 3.
In other words, when the human hand is naturally open, the glove body 3 is curved inward (palm side) as a whole, but the glove body 3 is formed in a shape corresponding to the natural open state of the human hand. The contour shapes of the forming support portions 15a and 15b of the three-dimensionally formed pieces 11a and 11b are formed so as to follow the curved three-dimensional shape of the palm portion of the glove body 3 designed based on this ergonomics.

  Further, as will be described later, the formation support portions 15a and 15b are provided with bending grooves 16a and 16b that form the bending operation portion 21 of the main body reinforcing piece 10, respectively.

  In other words, when the main body reinforcing piece 10 is sewn to the glove body 3, it is an essential design condition that the main body reinforcing piece 10 is easily bent corresponding to the bending operation portion of the glove body 3. In the present embodiment, a substantially linear portion of the main body reinforcing piece 10 to be bent corresponding to the bending operation portion of the glove body 3 is defined as a bending operation portion 21, and both ends of the substantially linear bending operation portion 21 are arranged. The bent grooves 16a and 16b are formed at the positions of the formation support portions 15a and 15b of the three-dimensionally formed pieces 11a and 11b corresponding to the portions.

  The main body reinforcing piece 10 and the three-dimensionally formed pieces 11a and 11b are in a state where the formation supporting portions 15a and 15b of the compatible body forming pieces 11a and 11b are respectively positioned and polymerized on the back surfaces of the bent portions 20a and 20b of the main body reinforcing piece 10. That is, in FIG. 4, the main body reinforcing piece 10 and the three-dimensionally formed pieces 11a and 11b are overlapped at a position where the forming support portions 15a and 15b are substantially in contact with the back surfaces of the bent portions 20a and 20b. (The hatched portion in FIG. 4 is a superposed portion), and is sutured and fixed integrally to the palm portion of the glove body 3 in this superposed state.

  Thereby, the palm reinforcing member 5 (10, 11a, 11b) is sewn along the three-dimensional outer peripheral surface of the glove body 3, and at this time, the edges of the compatible body forming pieces 11a, 11b. The forming support portions 15a and 15b serve as a solid curve forming edge of the main body reinforcing piece 10, and the main body reinforcing piece 10 completes a sewing structure along the curved solid shape of the palm portion of the glove main body 3 (FIG. 3 (a), (b) and (c)).

  In the actual manufacturing process of the reinforcing glove 1, the palm reinforcing member 5 (10, 11a, 11b) is also sewn to the glove body 3 when the glove body 3 is sewn. The stitched portion 30 between the piece 10 and the three-dimensionally formed pieces 11a and 11b is set at a position where the work object of the reinforcing glove 1 (the hoist wire cable C in the illustrated embodiment does not interfere with contact).

  Thus, the reinforcing glove 1 configured as described above is used by being worn repeatedly on the outside of the work glove 2 attached to the hand H as shown in FIG.

  In this case, in the palm reinforcing structure A of the reinforcing glove 1, the main body reinforcing piece 10 conforms to the curved three-dimensional shape of the palm portion of the glove main body 3 due to the three-dimensional forming action of the forming support portions 15 a and 15 b of the three-dimensional forming pieces 11 a and 11 b. Since the glove body 3 is made of a sewn structure, the glove body 3 can be attached to the glove body 3 from the beginning even though the palm portion is made of a thick and thin flexible leather body reinforcement piece 10. It can be deformed in accordance with natural hand movement, and good wearing workability can be ensured.

  Further, the bending support 16a and 16b for forming the bending operation part 21 of the main body reinforcing piece 10 are provided in the forming support portions 15a and 15b of the three-dimensionally formed pieces 11a and 11b, so that the main body reinforcing piece 10 is bent. The part 21 is fixed, and more stable operability and workability of the glove are secured.

  In particular, in the reinforcing glove 1 used for helicopter rescue as in the illustrated embodiment, the concave groove formed in the bending operation portion 21 functions as a sliding support portion for the wire cable C of the hoist. The location where the wire cable C slides can be obtained stably, and the wire cable C can be violated in the palm of the palm, so that the support is not stable, and the problem that it is difficult to use is effectively avoided.

  As mentioned above, overturning the common general knowledge about the leather materials used in conventional work gloves, and by devising the sewing structure, thick leather (though it is strong in strength but hard and flexible) Because it is difficult to bend, it is not easy to bend, it is not easy to wear, and workability is also poor, it is not suitable as a material for work gloves. As shown in the embodiment, the rescue glove 1 used in rescue of the helicopter rescues the helicopter to rescue helicopter. Various gloves used under severe conditions can reinforce especially worn and damaged palm parts, greatly extending the life of the gloves.

  By the way, in this type of conventional glove, it has become substantially impossible to use due to the rescue operation in one or two helicopter rescues. In the reinforcing glove 1 of the illustrated embodiment, It has been experimentally found that it can be used in more than 20 rescue operations.

  The above-described embodiment is merely a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope thereof. Such modifications are possible.

(1) In the illustrated embodiment, when the glove body 3 is sewn, the palm reinforcement member is sewn to the glove body 3 at the same time. It may be attached to the glove body 3 by a fixing method.

(2) Instead of the outer peripheral contour shape of the illustrated main body reinforcing piece 10, a shape as shown in FIG. 7 can be adopted. That is, in FIG. 7, the main body reinforcing piece 10 corresponds to the contour shape of the palm portion of the glove body 3 and also superposes the palm side of the base part of the first finger (thumb) and the second finger (index finger). At the same time, the entire palm side of the base part of the remaining three fingers (third finger (middle finger) to fifth finger (little finger)) is covered and polymerized.

(3) In the glove body 3 of the illustrated embodiment, the glove body 3 is an overglove type formed by cutting and opening a fingertip part of five fingers, but in a bag shape having only a wrist part opened. It may be formed and used as a single-use type that is worn directly on the hand H.

(4) In the illustrated embodiment, the glove body 3 is made of thin artificial leather because it is a reinforced glove worn over the work glove, but it is used alone as a work glove. In this case, various design changes can be made according to the purpose, such as a relatively strong thin leather.

(5) The reinforcing glove 1 of the illustrated embodiment can also be applied as a wheel operating glove for a wheelchair user. In this case, in the palm reinforcing structure A, the forming support portions 15a and 15b of the three-dimensionally formed pieces 11a and 11b are used. The bending operation part 21 of the main body reinforcing piece 10 formed by the provided bending grooves 16a and 16b has the function of the concave groove functioning as a wheel operation part of the wheelchair, so that the operation part of the wheel can be stably obtained. The risk of incorrect operation is effectively avoided.
