Description

Technical Field

[0001] The present invention relates to work gloves.

Background Art

[0002] Conventionally, thin work gloves made of a film such as polyethylene, which are worn when working, have been commercially available, and such work gloves are mainly disposable and are disposed of after the work is completed. Such film-type work gloves are manufactured by overlapping two thin films (polyethylene films), pressing a hand-shaped mold, cutting and welding at the peripheral edge of the glove (see, for example, Patent Document 1). Therefore, it can be manufactured at a lower cost than a glove having a three-dimensional shape such as a rubber glove, and has an advantage that the risk of chemical substances can be reduced in design.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since film-type work gloves cannot be formed into a three-dimensional shape like rubber gloves, etc., they are generally designed to be larger than a human hand and are used in a state where there is slack (a loose state) when worn on the hand. Then, since a gap is generated between the work glove and the hand when worn, only the hand moves inside the glove during work, resulting in a decrease in workability. Also, when working while wearing work gloves, it is important that the thumb and index finger fit into the finger insertion part of the gloves, which is related to workability. However, there are very large individual differences in the way the thumb and index finger are attached and their lengths among people. For this reason, it has been difficult to design work gloves with a finger insertion part having a length and width that fit both the thumb and index finger of everyone. The present invention has been made in view of the above circumstances, and an object thereof is to provide work gloves that fit the hand during wearing and improve workability.

Means for Solving the Problems

[0005] In order to achieve the above-described object, an embodiment of the present invention is a work glove to be worn during work, comprising: a tubular part having an opening and into which at least the wrist is inserted; a palm insertion part connected to an end of the tubular part opposite to the opening and into which the palm is inserted; and a finger insertion part provided to extend from the palm insertion part in a direction opposite to the tubular part and into which fingers are inserted. The finger insertion part has at least a thumb insertion part and an index finger insertion part into which the thumb and index finger are independently inserted. A first angle at which a thumb insertion part center line passing through the center in the width direction of the thumb insertion part and an index finger insertion part center line passing through the center in the width direction of the index finger insertion part intersect is formed to be larger than an angle at which a thumb center line passing through the center in the width direction of the thumb and an index finger center line passing through the center in the width direction of the index finger intersect in a state where all fingers are extended away from each other without applying force. In addition, one embodiment of the present invention is a work glove to be worn during work, which has an opening and a tubular portion into which at least the wrist is inserted, a palm insertion portion connected to an end of the tubular portion opposite to the opening and into which the palm is inserted, and a finger insertion portion provided to extend from the palm insertion portion in a direction opposite to the tubular portion and into which fingers are inserted. The finger insertion portion has at least a thumb insertion portion and an index finger insertion portion into which the thumb and the index finger are independently inserted. A first angle at which an edge of the thumb insertion portion on the index finger insertion portion side and an edge of the index finger insertion portion on the thumb insertion portion side intersect is formed to be larger than an angle at which an edge of the thumb on the index finger side and an edge of the index finger on the thumb side intersect when all fingers are extended while being separated from each other without applying force.

[0006] In addition, one embodiment of the present invention is that the finger insertion portion further has a ring finger insertion portion and a little finger insertion portion into which the ring finger and the little finger are independently inserted. A second angle at which an edge of the thumb insertion portion on the side away from the index finger insertion portion and an edge of the little finger insertion portion on the side away from the ring finger insertion portion intersect is formed to be larger than an angle at which an edge of the thumb on the side away from the index finger and an edge of the little finger on the side away from the ring finger intersect when all fingers are extended while being separated from each other without applying force. In addition, one embodiment of the present invention is that all fingers are inserted into the finger insertion portion, the tip of the index finger is brought into contact with the tip of the index finger insertion portion, and in a state where all fingers are extended while being separated from each other without applying force, the base of the edge of the thumb on the side away from the index finger and the edge of the palm connected to this base, and the base of the edge of the thumb insertion portion on the side away from the index finger insertion portion and the edge of the palm insertion portion connected to this base are in contact with each other, and the base of the edge of the little finger on the side away from the ring finger and the edge of the palm connected to this base, and the base of the edge of the little finger insertion portion on the side away from the ring finger insertion portion and the edge of the palm insertion portion connected to this base are in contact with each other, and the belly of the thumb and the tip of the thumb insertion portion are in contact with each other.

[0007] Further, in one embodiment of the present invention, a first dimension of the palm insertion portion connecting the first location at the edge of the palm insertion portion connected to the base of the thumb insertion portion on the side away from the index finger insertion portion and the second location at the edge of the palm insertion portion connected to the base of the little finger insertion portion on the side away from the ring finger insertion portion is formed to be smaller than the width of the cylindrical portion orthogonal to the extending direction of the cylindrical portion.

[0008] Further, in one embodiment of the present invention, the palm insertion portion and the cylindrical portion are formed in a tapered shape in which the width gradually increases from the first location and the second location toward the opening of the cylindrical portion, and the width of the cylindrical portion is formed to create a space on the thumb insertion portion side and the little finger insertion portion side when the wrist is inserted. Further, in one embodiment of the present invention, the cylindrical portion has a length that is inserted from the wrist to the middle portion of the forearm length, and the width of the cylindrical portion is formed to be a dimension that can accommodate the waste that has become unnecessary by performing work and turning the work glove inside out while holding the waste.

[0009] Further, in one embodiment of the present invention, a straight line passing through the edge of the palm insertion portion connected to the edge of the thumb insertion portion where the angle with the straight line passing through the edge of the thumb insertion portion on the side away from the index finger insertion portion is the smallest and the straight line passing through the edge of the thumb insertion portion intersect at a first intersection point, and a straight line passing through the edge of the palm insertion portion connected to the edge of the little finger insertion portion where the angle with the straight line passing through the edge of the little finger insertion portion on the side away from the ring finger insertion portion is the smallest and the straight line passing through the edge of the little finger insertion portion intersect at a second intersection point. A point where a straight line passing through the first intersection point and the second intersection point intersects with the edge of the palm insertion portion connected to the edge of the thumb insertion portion is a third intersection point, and a point where a straight line passing through the first intersection point and the second intersection point intersects with the edge of the palm insertion portion connected to the edge of the little finger insertion portion is a fourth intersection point. Then, the third intersection point is the first location, the fourth intersection point is the second location, and the first dimension is the length connecting the third intersection point and the fourth intersection point. Further, in one embodiment of the present invention, the cylindrical portion is characterized by having a length that can be inserted from the wrist to the elbow.

Advantages of the Invention

[0010] According to one embodiment of the present invention, the first angle at which the center line of the thumb insertion portion passing through the center in the width direction of the thumb insertion portion intersects the center line of the index finger insertion portion passing through the center in the width direction of the index finger insertion portion is larger than the angle at which the center line of the thumb passing through the center in the width direction of the thumb and the center line of the index finger passing through the center in the width direction of the index finger intersect in a state where all fingers are stretched apart from each other without applying force. Therefore, it is advantageous for fitting to the hand during wearing and improving workability. That is, when performing work with the hand wearing the work glove, tension is applied in the direction in which the thumb side and the little finger side of the palm are pulled against each other and in the direction in which the base and the tip of the thumb are pulled against each other. By the belly of the thumb abutting against the tip of the thumb insertion portion, the work glove fits tightly on the hand and is difficult to come off, improving workability. Further, according to one embodiment of the present invention, the first angle at which the edge of the thumb insertion portion on the index finger insertion portion side intersects the edge of the index finger insertion portion on the thumb insertion portion side is larger than the angle at which the edge of the thumb on the index finger side and the edge of the index finger on the thumb side intersect in a state where all fingers are stretched apart from each other without applying force. Therefore, it is advantageous for fitting to the hand during wearing and improving workability. That is, when performing work with the hand wearing the work glove, tension is applied in the direction in which the thumb side and the little finger side of the palm are pulled against each other and in the direction in which the base and the tip of the thumb are pulled against each other. By the belly of the thumb abutting against the tip of the thumb insertion portion, the work glove fits tightly on the hand and is difficult to come off, improving workability.

[0011] In addition, if the second angle at which the edge of the thumb insertion part on the side away from the index finger insertion part intersects with the edge of the little finger insertion part on the side away from the ring finger insertion part is formed to be larger than the angle at which the edge of the thumb on the side away from the index finger and the edge of the little finger on the side away from the ring finger intersect when all fingers are extended away from each other without applying force, it is advantageous for fitting to the hand during wearing and improving workability. That is, when working with the hand wearing the work glove, a tension is applied in the direction in which the glove tends to slide from the thumb and little finger toward the wrist, which is advantageous for the work glove to fit the hand and improve workability. Further, with all fingers inserted into the finger insertion parts and the tip of the index finger abutted against the tip of the index finger insertion part, in a state where all fingers are extended away from each other without applying force, the base of the edge of the thumb on the side away from the index finger and the edge of the palm connected to this base abut against the base of the edge of the thumb insertion part on the side away from the index finger insertion part and the edge of the palm insertion part connected to this base, and the base of the edge of the little finger on the side away from the ring finger and the edge of the palm connected to this base abut against the base of the edge of the little finger insertion part on the side away from the ring finger insertion part and the edge of the palm insertion part connected to this base, and the belly of the thumb abuts against the tip of the thumb insertion part. Such a configuration is advantageous for fitting to the hand during wearing and improving workability.

[0012] In addition, if the first dimension of the palm insertion part connecting the first location of the edge of the palm insertion part connected to the base of the thumb insertion part on the side away from the index finger insertion part and the second location of the edge of the palm insertion part connected to the base of the little finger insertion part on the side away from the ring finger insertion part is formed to be smaller than the width of the cylindrical part perpendicular to the extending direction of the cylindrical part, it is advantageous for fitting to the hand during wearing and improving workability. That is, when working with the hand wearing the work glove, a tension is applied in the direction in which the thumb side and the little finger side of the palm are pulled toward each other and in the direction in which the base and the tip of the thumb are pulled toward each other. By the joints at the base of the thumb and the base of the little finger abutting against the palm insertion part, the work glove fits the hand and is difficult to come off, improving workability.

[0013] In addition, if the palm insertion part and the cylindrical part are formed in a tapered shape in which the width gradually increases from the first location and the second location toward the opening of the cylindrical part, and the width of the cylindrical part is formed to have a dimension that creates a space on the thumb insertion part side and the little finger insertion part side with the wrist inserted, then, by the cylindrical part spreading evenly on the thumb insertion part side and the little finger insertion part side, it is advantageous in improving workability without causing interference. In addition, if the cylindrical part has a length that allows it to be inserted from the wrist to the middle part of the forearm, and the width of the cylindrical part is formed to have a dimension that allows waste that has become unnecessary during work to be contained by turning the work glove inside out with the waste held, then it can be used as a garbage bag for containing and discarding waste, and the cylindrical part can be tied and closed after containing the waste.

[0014] Also, the point where the straight line passing through the edge of the palm insertion part connected to the edge of the thumb insertion part with the smallest angle with respect to the straight line passing through the edge of the thumb insertion part on the side away from the index finger insertion part intersects the straight line passing through the edge of the thumb insertion part is defined as the first intersection point, and the point where the straight line passing through the edge of the palm insertion part connected to the edge of the little finger insertion part with the smallest angle with respect to the straight line passing through the edge of the little finger insertion part on the side away from the ring finger insertion part intersects the straight line passing through the edge of the little finger insertion part is defined as the second intersection point. The point where the straight line passing through the first intersection point and the second intersection point intersects the straight line passing through the edge of the palm insertion part connected to the edge of the thumb insertion part is defined as the third intersection point, and the point where the straight line passing through the first intersection point and the second intersection point intersects the straight line passing through the edge of the palm insertion part connected to the edge of the little finger insertion part is defined as the fourth intersection point. If the first dimension is the length connecting the third intersection point and the fourth intersection point, it is advantageous for easily determining the first dimension. In addition, if the cylindrical part is configured to have a length that allows it to be inserted from the wrist to the elbow, it is advantageous in suppressing contact of not only the hand and the wrist but also the forearm and the elbow with the work object during work.

Mode for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The work glove is worn on the hand when performing various operations, for example, waste treatment operations such as handling dirt and food processing operations. In this embodiment, a case where the work glove is worn on the hand and a waste treatment operation is performed will be described. Further, the work glove of this embodiment can accommodate waste by turning it inside out while holding the waste after performing the waste treatment operation, and it also serves as a glove for waste treatment work and a garbage bag for accommodating waste. Specifically, for example, when changing a diaper, after putting on work gloves and changing the diaper, the used diaper can be contained in the work gloves and discarded as it is by turning it over while holding the used diaper.

[0017] As shown in FIGS. 1 and 2, the work glove 10 includes a tubular portion 12, a palm insertion portion 14, and a finger insertion portion 16. For the work glove 10, a film, non-woven fabric, etc. can be used. In this embodiment, it is made of colorless transparent or translucent polyethylene, and the outer or inner side of the work glove 10 is embossed. In this embodiment, a polyethylene film sheet is folded in half or stacked in two, and is manufactured by being cut by heat welding with a molding machine. However, the manufacturing method of the work glove 10 is not limited to this manufacturing method, and various conventionally known manufacturing methods such as ultrasonic welding can be adopted. Also, the material constituting the work glove 10 is not limited to polyethylene, and any flexible material having airtightness and water impermeability can be used, such as polypropylene, polyester, nylon, ethylene-vinyl acetate copolymer resin, thermoplastic elastomer, polyvinyl chloride, etc., regardless of whether it is transparent or not.

[0018] The tubular portion 12 has an opening 1202 for inserting and removing a hand into and from the work glove 10, and the tubular portion 12 is at least a portion where the wrist is inserted. The palm insertion portion 14 is connected to the end of the tubular portion 12 opposite to the opening 1202 and is a portion where the palm is inserted. The finger insertion portion 16 extends from the palm insertion portion 14 in the opposite direction to the tubular portion 12 and is a portion where the fingers are inserted. The finger insertion portion 16 has a thumb insertion portion 18, an index finger insertion portion 20, a middle finger insertion portion 22, a ring finger insertion portion 24, and a little finger insertion portion 26 into which the thumb, index finger, middle finger, ring finger, and little finger are independently inserted. In addition, in the present embodiment, the extending direction (hand insertion direction) of the work glove 10 is defined as the Y direction or the length direction shown in FIG. 1, and the direction orthogonal to the extending direction (Y direction) of the work glove 10 is defined as the X direction or the width direction.

[0019] The angle between the thumb insertion part 18 and the index finger insertion part 20 of the work glove 10 will be described. The angle between the thumb insertion part 18 and the index finger insertion part 20 is formed to be larger than the angle between the thumb and the index finger in a state where all fingers are extended with no force applied and separated from each other. Specifically, in the present embodiment, for example, the thumb insertion part 18 and the index finger insertion part 20 are formed using the angles calculated by the following calculation methods 1 and 2. Note that other calculation methods may be used to calculate the angle.

[0020] First, in calculation method 1, as shown in FIG. 3(A), a line passing through the center in the width direction of the thumb insertion part 18 from the vertex 18A of the thumb insertion part 18 is defined as the thumb insertion part center line 18B, and a line passing through the center in the width direction of the index finger insertion part 20 from the vertex 20A of the index finger insertion part 20 is defined as the index finger insertion part center line 20B. Then, the angle between the thumb insertion part 18 and the index finger insertion part 20 is the angle α (first angle) at which the thumb insertion part center line 18B and the index finger insertion part center line 20B intersect. The angle α (first angle) is formed to be larger than the angle at which a thumb center line passing through the center in the width direction of the thumb and an index finger center line passing through the center in the width direction of the index finger intersect in a state where all fingers are extended with no force applied and separated from each other. Note that since the thumb insertion part 18 and the index finger insertion part 20 are not symmetric with respect to the thumb insertion part center line 18B and the index finger insertion part center line 20B, the line passing through the approximate center is also included. The same applies to the thumb and the index finger.

[0021] Also, in calculation method 2, as shown in FIG. 3(B), the angle between the thumb insertion part 18 and the index finger insertion part 20 is the angle α (first angle) at which the edge 1802 of the thumb insertion part 18 on the index finger insertion part 20 side and the edge 2002 of the index finger insertion part 20 on the thumb insertion part 18 side intersect. The angle α (the first angle) is formed to be larger than the angle at which the edge of the thumb on the index finger side and the edge of the index finger on the thumb side cross when all fingers are extended with no force applied and separated from each other. Since the edges 1802 of the thumb insertion part 18 and 2002 of the index finger insertion part 20 are not straight lines, the approximate lines along the edges 1802 and 2002 are also included. The same applies to the edges of the thumb and the index finger.

[0022] Next, the angle between the thumb insertion part 18 and the little finger insertion part 26 of the work glove 10 will be described. The angle between the thumb insertion part 18 and the little finger insertion part 26 is formed to be larger than the angle between the thumb and the little finger when all fingers are extended with no force applied and separated from each other. Specifically, as shown in FIG. 1, the angle between the thumb insertion part 18 and the little finger insertion part 26 is the angle β (the second angle) at which the edge 1802 of the thumb insertion part 18 on the side away from the index finger insertion part 20 and the edge 2602 of the little finger insertion part 26 on the side away from the ring finger insertion part 24 cross. The angle β (the second angle) is formed to be larger than the angle at which the edge of the thumb on the side away from the index finger and the edge of the little finger on the side away from the ring finger cross when all fingers are extended with no force applied and separated from each other. Similar to the above, since the edge 2602 of the little finger insertion part 26 is not a straight line, the approximate line along the edge 2602 is also included. The same applies to the edge of the little finger. An example of the calculation method of the angle β (the second angle) will be described later (see FIG. 4).

[0023] Next, the length of the portion of the edge that is recessed inward in the direction of approaching each other in the palm insertion part 14 will be described. As shown in FIG. 1, the portion that is recessed inward of the edge 1402 of the palm insertion part 14 connected to the base of the thumb insertion part 18 on the side away from the index finger insertion part 20 is defined as point N (the first location), and the portion that is recessed inward of the edge 1402 of the palm insertion part 14 connected to the base of the little finger insertion part 26 on the side away from the ring finger insertion part 24 is defined as point M (the second location). Then, the length of the portion of the edge that is recessed inward in the palm insertion part 14 is the length U (the first dimension) of the palm insertion part 14 connecting point N and point M. The length U (first dimension) of the palm insertion part 14 is formed to be smaller than the width of the cylindrical part 12 in the direction orthogonal to the extending direction of the cylindrical part 12. An example of the method for calculating the length U (first dimension) will be described later (see FIG. 4).

[0024] Next, the length and width of the cylindrical part 12 will be described. The cylindrical part 12 of the present embodiment extends in the Y direction (length direction) and has a length that allows it to be inserted from the wrist to the middle part of the length of the forearm as shown in FIG. 2. For this reason, the wrist and forearm can be inserted into the cylindrical part 12.

[0025] The width of the cylindrical part 12 is formed to be such that a space is created on the thumb insertion part 18 side and the little finger insertion part 26 side when the wrist is inserted. That is, as shown in FIG. 2, the width of the cylindrical part 12 is formed to be a dimension that creates a space with respect to the wrist and forearm on both sides in the width direction of the cylindrical part 12 when the wrist is inserted (a dimension that allows slack on the thumb side and the little finger side). Also, the width of the cylindrical part 12 is formed to be a dimension that allows the waste (for example, used diapers) that has become unnecessary by performing work to be accommodated by turning the work glove 10 inside out while holding the waste. Therefore, as described above, by grasping the waste and turning the cylindrical part 12 inside out, the work glove 10 can be used as a garbage bag for accommodating and discarding the waste. Further, since the cylindrical part 12 has a length that allows it to be inserted from the wrist to the middle part of the length of the forearm as described above, the cylindrical part 12 can be tied and closed after accommodating the waste.

[0026] Also, as shown in FIG. 1, the palm insertion part 14 and the cylindrical part 12 are formed in a tapered shape in which the width gradually increases as they go from the point N (first location) and the point M (second location) toward the opening 1202 of the cylindrical part 12.

[0027] Next, with reference to FIG. 4, the method for calculating the angle β (second angle) and the length U (first dimension) will be described. The following calculation method is an example, and the angle β (second angle) and the length U (first dimension) may be calculated by other calculation methods. First, let a straight line connecting the finger crotch 22B between the middle finger insertion part 22 and the index finger insertion part 20 and the finger crotch 22C between the middle finger insertion part 22 and the ring finger insertion part 24 be line g. Let a straight line passing through the midpoint of line g from the finger crotch 22B to the finger crotch 22C and the apex 22A of the middle finger insertion part 22 be line h.

[0028] And let the length X of line h from the apex 22A of the middle finger insertion part 22 to line g be the length of the middle finger insertion part 22. Extend line h to the cylindrical part 12, and let the point where the length X is extended three times be point P. Let a perpendicular line to line h passing through point P be line i.

[0029] Let a straight line passing through the edge 1802 of the thumb insertion part 18 on the side away from the index finger insertion part 20 be line b, and let a straight line passing through the edge 2602 of the little finger insertion part 26 on the side away from the ring finger insertion part 24 be line c. Let the intersection point of line b and line c be point O, and let the angle at which line b and line c intersect be angle β (the second angle).

[0030] And let the area including the edge 1402 of the palm insertion part 14 connected to the edge of the thumb insertion part 18 from line i to line b be area Y1, and let the area including the edge 1402 of the palm insertion part 14 connected to the edge of the little finger insertion part 26 from line i to line c be area Y2. Within area Y1, let a straight line passing through the edge 1402 of the palm insertion part 14 connected to the edge of the thumb insertion part 18 where the angle with line b is the smallest be line e. That is, search for the position where the angle at which line b and line e intersect within area Y1 is the smallest angle and determine line e. Similarly, within area Y2, let a straight line passing through the edge 2602 of the palm insertion part 14 connected to the edge of the little finger insertion part 26 where the angle with line c is the smallest be line d. That is, search for the position where the angle at which line c and line d intersect within area Y2 is the smallest angle and determine line d.

[0031] Let the intersection point of line b and line e be point Q (the first intersection point), let the intersection point of line c and line d be point R (the second intersection point), and let a straight line passing through intersection point Q and intersection point R be line f. Let the point where the line f intersects the edge 1402 of the palm insertion part 14 connected to the edge of the thumb insertion part 18 be point N (the third intersection point and the first location), and let the point where the line f intersects the edge 1402 of the palm insertion part 14 connected to the edge of the little finger insertion part 26 be point M (the fourth intersection point and the second location). And let the length connecting point N (the third intersection point) and point M (the fourth intersection point) be length U (the first dimension).

[0032] Also, let the intersection point of the line i and the edge 1002 of the working glove 10 on the thumb insertion part 18 side be point S, let the intersection point of the line i and the edge 1002 of the working glove 10 on the little finger insertion part 26 side be point T, and let the length connecting point S and point T be length V. In this way, the angle β (the second angle) and the length U (the first dimension) are calculated, and the angle α (the first angle) is calculated by the above-described calculation method to form the working glove 10.

[0033] Next, with reference to FIG. 5, an example of the dimensions of the working glove 10 will be described. As shown in FIG. 5, the length L in the Y direction of the working glove 10 of the present embodiment (the length from the vertex 22A of the middle finger insertion part 22 to the opening 1202) is 44 cm, and it is preferably 35 cm or more (L = 44 cm). The width W in the X direction of the opening 1202 of the cylindrical part 12 of the present embodiment is 20.7 cm, and it is preferably 14.4 cm or more (W = 20.7 cm). Also, the length U (the length from point N to point M) is 11.3 cm, and it is preferably 12 cm or less (U = 11.3 cm). And the length V (the length from point S to point T) is 17.7 cm, and it is preferably 14.4 cm or more (V = 17.7 cm).

[0034] Next, with reference to FIGS. 6 to 9, the working glove 10 during use will be described. When wearing the work glove 10, first, widen the opening 1202 of the tubular part 12 (see Fig. 1), hold the vicinity of the opening 1202 with the opposite hand, and insert the fingers, palm, wrist, and forearm in this order, and further insert the fingers into the respective finger insertion parts 16. Then, pull the vicinity of the opening 1202 until the tip of the index finger abuts against the tip part (apex 20A) of the index finger insertion part 20, and the wearing is completed.

[0035] When wearing the work glove 10, since force is applied to the fingers for insertion, all the fingers are inserted into the finger insertion parts 16 of the work glove 10, and immediately after wearing with the tip of the index finger abutted against the tip part (apex 20A) of the index finger insertion part 20, all the fingers with force applied are separated and extended from each other. As shown in Fig. 6(A), when force is applied to the fingers and the angle between the thumb and the index finger is widely opened, the belly of the thumb does not abut against the tip of the thumb insertion part 18 (see D1).

[0036] After that, when all the fingers are separated and extended from each other without applying force, the fingers separate from each other and bend into a natural shape at the joints, and the thumb side and the little finger side of the palm bend inward into a natural shape. This state is defined as the state where "the hand bends into a natural shape". Then, since the angle α (see Fig. 3) between the thumb insertion part 18 and the index finger insertion part 20 is formed larger than the angle between the thumb and the index finger in the state where all the fingers are separated and extended from each other without applying force, as shown by the arrow in Fig. 6(B), tension is applied in the direction in which the thumb side and the little finger side of the palm are pulled toward each other and in the direction in which the base and the tip of the thumb are pulled toward each other. As a result, the belly of the thumb abuts against the tip of the finger insertion part 16, and the thumb insertion part 18 fits onto the thumb.

[0037] Also, when the hand bends into a natural shape, the length U (see FIG. 1) connecting point N and point M of the palm insertion part 14 on the hand is formed to be smaller than the width of the cylindrical part 12 orthogonal to the extending direction of the cylindrical part 12. Therefore, as indicated by the arrow in FIG. 7(A), tension is applied in the direction in which the thumb side and the little finger side of the palm are pulled toward each other. As a result, the base of the edge of the thumb on the side away from the index finger and the edge of the palm connected to this base, and the base of the edge of the thumb insertion part 18 on the side away from the index finger insertion part 20 and the edge of the palm insertion part 14 connected to this base come into contact (see D2), and the base of the edge of the little finger on the side away from the ring finger and the edge of the palm connected to this base, and the base of the edge of the little finger insertion part 26 on the side away from the ring finger insertion part 24 and the edge of the palm insertion part 14 connected to this base come into contact (see D3), and the working glove 10 fits on the palm. That is, when the hand bends into a natural shape and tension is applied in the direction in which the thumb side and the little finger side of the palm are pulled toward each other, as shown in FIG. 7(B), at the base bone E1 of the thumb (the metacarpal phalangeal joint of the thumb) and the base bone E2 of the little finger (the metacarpal phalangeal joint of the little finger), points N and M where the width direction (X direction) of the working glove 10 becomes narrower are caught, making it difficult for the working glove 10 to come off. As a result, the working glove 10 fits on the palm.

[0038] Also, when the hand bends into a natural shape, the angle β (see FIG. 1) between the thumb insertion part 18 and the little finger insertion part 26 is formed to be larger than the angle between the thumb and the little finger in a state where all fingers are extended away from each other without applying force. Therefore, as indicated by the arrow in the figure, tension is applied to the working glove 10 in the direction (downward) from the thumb and the little finger toward the wrist. As a result, the fingertips of the thumb and the index finger fit better into the finger insertion part 16. In addition, since the middle finger, the ring finger, and the little finger have less impact on workability compared to the thumb and the index finger, they are formed with some looseness.

[0039] In addition, since the palm insertion part 14 and the cylindrical part 12 are formed in a tapered shape whose width gradually increases from the point N (the first location) and the point M (the second location) toward the opening 1202 of the cylindrical part 12 (see FIG. 1), as shown in FIG. 9, when the work glove 10 is worn, the cylindrical part spreads well-balancedly on the thumb insertion part side and the little finger insertion part side, so that the work can be easily performed without being obstructive.

[0040] Furthermore, as shown in FIG. 9, since the width of the cylindrical part 12 is formed to have spaces F1 and F2 on the thumb insertion part 18 side and the little finger insertion part 26 side in a state where the wrist is inserted, by turning the work glove 10 inside out while holding near the opening 1202 of the cylindrical part 12 in a state of grasping the waste, the work glove 10 can be used as a garbage bag for containing and discarding the waste, and the cylindrical part can be tied and closed after containing the waste.

[0041] As described above, in the work glove 10 of the present embodiment, the angle α (the first angle) at which the thumb insertion part center line 18B passing through the center in the width direction of the thumb insertion part 18 and the index finger insertion part center line 20B passing through the center in the width direction of the index finger insertion part 20 intersect is larger than the angle at which the thumb center line passing through the center in the width direction of the thumb and the index finger center line passing through the center in the width direction of the index finger intersect in a state where all fingers are extended with no force applied and separated from each other. Therefore, it is advantageous for fitting on the hand and improving workability when worn. That is, when working with the hand wearing the work glove 10, tension is applied in the direction in which the thumb side and the little finger side of the palm are pulled toward each other and in the direction in which the base and the tip of the thumb are pulled toward each other, and the belly of the thumb abuts against the tip of the thumb insertion part 18, so that the work glove 10 fits on the hand and is difficult to come off, improving workability. In addition, in the work glove 10 of the present embodiment, the angle α (first angle) at which the edge 1902 of the thumb insertion portion 18 on the index finger insertion portion 20 side and the edge 2002 of the index finger insertion portion 20 on the thumb insertion portion 18 side intersect is the angle at which the edge of the thumb on the index finger side and the edge of the index finger on the thumb side intersect in a state where all fingers are extended away from each other without applying force. Since it is formed larger, it is advantageous for fitting on the hand during wearing and improving workability. That is, when working with the hand wearing the work glove 10, tension is applied in the direction in which the palm side of the thumb and the little finger side are pulled toward each other and in the direction in which the base and the tip of the thumb are pulled toward each other. By the belly of the thumb abutting against the tip of the thumb insertion portion 18, the work glove 10 fits on the hand and is difficult to come off, improving workability.

[0042] Further, the angle β (second angle) at which the edge 1802 of the thumb insertion portion 18 on the side away from the index finger insertion portion 20 and the edge 2602 of the little finger insertion portion 26 on the side away from the ring finger insertion portion 24 intersect is the angle at which the edge of the thumb on the side away from the index finger and the edge of the little finger on the side away from the ring finger intersect in a state where all fingers are extended away from each other without applying force. Since it is formed larger, it is advantageous for fitting on the hand during wearing and improving workability. That is, when working with the hand wearing the work glove 10, tension is applied in the direction in which the work glove 10 tends to slide from the thumb and the little finger toward the wrist, which is advantageous for the work glove 10 to fit on the hand and improve workability. Also, with all fingers inserted into the finger insertion part 16 and the tip of the index finger abutted against the tip of the index finger insertion part 20 (apex 20A), with all fingers separated from each other and extended without applying force, the base of the edge of the thumb on the side away from the index finger and the edge of the palm connecting to this base, and the base of the edge 1802 of the thumb insertion part 18 on the side away from the index finger insertion part 20 and the edge 1402 of the palm insertion part 14 connecting to this base abut, and the base of the edge of the little finger on the side away from the ring finger and the edge of the palm connecting to this base, and the base of the edge 2602 of the little finger insertion part 26 on the side away from the ring finger insertion part 24 and the edge 1402 of the palm insertion part 14 connecting to this base abut, and the belly of the thumb and the tip of the thumb insertion part 18 abut. Therefore, it is advantageous for improving workability by fitting to the hand during wearing.

[0043] Also, the length U (first dimension) of the palm insertion part 14 connecting the point N (first location) of the edge 1402 of the palm insertion part 14 connected to the base of the thumb insertion part 18 on the side away from the index finger insertion part 20 and the point M (second location) of the edge 1402 of the palm insertion part 14 connected to the base of the little finger insertion part 26 on the side away from the ring finger insertion part 24 is formed to be smaller than the width of the cylindrical part 12 orthogonal to the extending direction of the cylindrical part 12. Therefore, it is advantageous for improving workability by fitting to the hand during wearing. That is, when working with the hand wearing the work glove 10, tension is applied in the direction in which the thumb side and the little finger side of the palm are pulled against each other and in the direction in which the base and the tip of the thumb are pulled against each other. The joints at the base of the thumb and the base of the little finger abut against the palm insertion part 14, so that the work glove 10 fits onto the hand and is difficult to come off, improving workability.

[0044] Also, the palm insertion part 14 and the cylindrical part 12 are formed in a tapered shape such that the width gradually increases from the point N (first location) and the point M (second location) toward the opening 1202 of the cylindrical part 12. The width of the cylindrical part 12 is formed to create a space on the thumb insertion part 18 side and the little finger insertion part 26 side with the wrist inserted. Therefore, it is advantageous for improving workability without causing interference as the cylindrical part 12 spreads well-balancedly on the thumb insertion part 18 side and the little finger insertion part 26 side. In addition, the cylindrical portion 12 has a length that allows it to be inserted from the wrist to the middle part of the forearm. Since the width of the cylindrical portion 12 is formed to have a dimension that can accommodate waste in a state where the waste, which has become unnecessary by performing the work, is grasped by turning the work glove 10 inside out, it can be used as a garbage bag for containing and discarding the waste, and the cylindrical portion 12 can be tied and closed after the waste is contained.

[0045] Also, let the point where the straight line (line e) passing through the edge 1402 of the palm insertion part 14 connected to the edge of the thumb insertion part 18 where the angle with the straight line (line b) passing through the edge 1802 of the thumb insertion part 18 on the side away from the index finger insertion part 20 is the smallest, and the straight line (line b) passing through the edge 1802 of the thumb insertion part 18 intersects be point Q (the first intersection point). Let the point where the straight line (line d) passing through the edge 1402 of the palm insertion part 14 connected to the edge of the little finger insertion part 26 where the angle with the straight line (line c) passing through the edge 2602 of the little finger insertion part 26 on the side away from the ring finger insertion part 24 is the smallest, and the straight line (line c) passing through the edge 2602 of the little finger insertion part 26 intersects be point R (the second intersection point). Let the straight line (line f) passing through point Q (the first intersection point) and point R (the second intersection point), and the point where the straight line (line f) intersects the edge 1402 of the palm insertion part 14 connected to the edge of the thumb insertion part 18 be point N (the third intersection point). Let the point where the straight line (line f) passing through point Q (the first intersection point) and point R (the second intersection point), and the edge 1402 of the palm insertion part 14 connected to the edge of the little finger insertion part 26 intersects be point M (the fourth intersection point). Since the length U (the first dimension) is the length connecting point N (the third intersection point) and point M (the fourth intersection point), it is advantageous for easily determining the length U (the first dimension).

[0046] The cylindrical portion 12 of the work glove 10 described above had a length that allowed it to be inserted from the wrist to the middle part of the forearm. However, as shown in the work glove 10A in FIG. 10(A), the cylindrical portion 12 may have a length that allows only the wrist to be inserted. This improves workability and is advantageous for easy attachment and detachment. Also, as shown in the work glove 10B in FIG. 10(B), the cylindrical portion 12 may have a length that allows it to be inserted from the wrist to the elbow. This is advantageous for suppressing the contact of not only the hand and the wrist but also the forearm and the elbow with the work object during work.

[0047] In the work glove 10 of the present embodiment, the finger insertion portion 16 is configured to include a thumb insertion portion 18, an index finger insertion portion 20, a middle finger insertion portion 22, a ring finger insertion portion 24, and a little finger insertion portion 26 into which the thumb, index finger, middle finger, ring finger, and little finger are independently inserted. However, the configuration of the finger insertion portion 16 is not limited to this. That is, as long as it has a thumb insertion portion 18 and an index finger insertion portion 20 into which the thumb and index finger are independently inserted, the shape of the finger insertion portion into which the other fingers (middle finger, ring finger, little finger) are inserted is arbitrary. Specifically, in addition to the thumb insertion portion 18 and the index finger insertion portion 20, by providing another finger insertion portion into which the middle finger, ring finger, and little finger are inserted together, the finger insertion portion may be configured to have three insertion portions. In addition, in addition to the thumb insertion portion 18 and the index finger insertion portion 20, a middle finger insertion portion into which the middle finger is independently inserted and another finger insertion portion into which the ring finger and little finger are inserted together may be provided, or a little finger insertion portion into which the little finger is independently inserted and another finger insertion portion into which the middle finger and ring finger are inserted together may be provided, so that the finger insertion portion may be configured to have four insertion portions.
