Gloves for handling transported goods

Abstract

This glove reduces the effort required by the person carrying heavy objects and is suitable for use with a power assist suit. [Solution] The glove 1 for carrying goods has a main body 2, a thumb portion 3, an index finger portion 4, a middle finger portion 5, a ring finger portion 6, and a little finger portion 7. The surface of the main body 2 has a first rubber coating 11 and a second coating 12 further provided on the palm side. The middle finger portion 5 and the ring finger portion 6 have block-shaped locking members 13 on the palm side. The locking members 13 are provided between the metacarpophalangeal joint G and the proximal interphalangeal joint F. When a carrier holds a box T, the corners of the box T are locked by the locking members 13. Since the locking members 13 are held between the bottom of the box T and the proximal phalanges C of the middle and ring fingers, the carrier can easily carry the box T. Alternatively, a second locking member 13a may be provided between the distal interphalangeal joint and the metacarpophalangeal joint.

Description

Technical Field

[0001] The present invention relates to gloves suitable for carrying heavy loads.

Background Art

[0002] When carrying heavy loads, gloves with anti-slip processing on the palm are generally used. For example, as disclosed in Patent Document 1, there is a glove in which anti-slip protrusions made of an elastic member are provided on substantially the entire surface of the palm.

[0003] Such conventional work gloves have a plurality of anti-slip protrusions formed on the palm. When carrying a load, the frictional resistance between the glove and the load increases, so there is an advantage that the load is difficult to slip.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the work gloves described in Patent Document 1 provide a certain degree of anti-slip effect due to the frictional force between the anti-slip protrusions of the glove and the load when the load is heavy. However, when a person moves while holding the load, the load will gradually slip, so an operation such as readjusting the hold is necessary. Also, the frictional force between the inner surface of the glove and the person's hand is not very large, so the glove will gradually slip off the hand.

[0006] Thus, while some conventional work gloves have anti-slip surfaces, their anti-slip effect is insufficient when carrying heavy objects. Furthermore, conventional work gloves do not reduce the effort required of the person carrying heavy objects.

[0007] Furthermore, in recent years, power assist suits have been used to assist the movements of carriers in order to reduce the burden on carriers (see Patent Document 2). When such a power assist suit is used, it is possible to reduce the burden on carriers when lifting heavy objects or when in a crouched position by assisting the muscles of the waist, thereby reducing the burden on carriers when transporting objects.

[0008] However, since this type of power assist suit assists the muscles of the user's waist, the hands that carry the object still rely on human strength as before. Therefore, even with the use of a power assist suit, the effort required of the hands is not reduced.

[0009] The present invention aims to provide gloves that can reduce the effort required by a person when carrying heavy loads. Another objective of the present invention is to provide gloves that reduce the effort required by the hands when using a power assist suit, thereby enabling the carrying of heavier loads than before. [Means for solving the problem]

[0010] To achieve the above objective, the present invention provides a glove for carrying transported goods, which is a glove usable when transporting transported goods, comprising a main body that covers the palm and the back of the hand, and a thumb portion, index finger portion, middle finger portion, ring finger portion, and little finger portion that covers each finger, and having a locking surface formed on the palm side of any of the thumb portion, index finger portion, middle finger portion, ring finger portion, or little finger portion, between the location of the metacarpophalangeal joint of the hand and the location of the proximal interphalangeal joint, and having a height that rises from the installation location, and having a locking member provided such that when the transported goods are held, the locking surface is positioned between the transported goods and the middle or distal phalanx of the hand, and the transported goods are locked in place.

[0011] According to the present invention's glove for carrying objects, when a carrier holds an object, such as a box-shaped object, the locking surface of the locking member is positioned between the object and the middle or distal phalanges of the hand, and the locking surface locks onto the object. As a result, the object can be held by the middle or distal phalanges of the hand via the locking member, making it easier to grasp the object.

[0012] Alternatively, the glove for carrying goods of the present invention may be provided with a second locking member, which is formed on the palm side of any of the thumb, index finger, middle finger, ring finger, or little finger portions, between the location of the distal interphalangeal joint and the location of the metacarpophalangeal joint, has a locking surface that rises from the installation location, and has a height such that when the glove is held, the locking surface is positioned between the goods and the distal phalanges of the hand to lock the goods.

[0013] With this second locking member, when a carrier holds an object, the locking surface of the locking member is positioned between the object and the distal phalanx of the hand, and the locking surface locks onto the object. As a result, the object can be held by the distal phalanx of the hand via the locking member, making it easier to grasp the object.

[0014] In the glove for carrying goods according to the present invention, the locking member or the second locking member may have a locking surface height that is 1 / 5 or more and 4 / 5 of the outer diameter when the finger portion on which the locking member or the second locking member is provided is cylindrical. If the locking member is less than 1 / 5 of the outer diameter when the finger portion is cylindrical, it becomes difficult to lock the goods when holding them. Conversely, if the locking member exceeds 4 / 5 of the outer diameter when the finger portion is cylindrical, inconveniences such as difficulty bending the fingers when not holding goods will occur.

[0015] Furthermore, in the glove for carrying transported goods according to the present invention, the locking member or the second locking member may be provided at two locations on the middle finger and the ring finger. With this configuration, the transported goods can be secured by two locking members on one hand, making it possible to transport even heavy objects.

[0016] Furthermore, in the glove for transporting goods of the present invention, at least the palm side of the finger portion on which the locking member or the second locking member is provided is coated with a rubber material, and the locking member may be bonded to or integrally molded with the surface of the coating. With this configuration, the bond between the rubber material on the palm side and the locking member becomes strong, making it possible to transport even heavy objects.

[0017] Furthermore, in the glove for carrying transported goods according to the present invention, the locking member or the second locking member may be formed in a fan shape along the surface of the finger portion on which the locking member or the second locking member is provided, when viewed from the fingertip side. With this configuration, the end of the locking member in the width direction will not get excessively caught on the transported goods, and the locking member will not get in the way when releasing the transported goods.

[0018] Furthermore, in the glove for carrying goods of the present invention, the locking member or the second locking member may be formed such that the angle between the locking surface and the mounting surface is acute when viewed from the side with the palm side facing forward. With this configuration, when a carrier holds a box or other item, the bottom surface of the item is locked by the locking surface formed at an acute angle with the mounting surface, so that the item is less likely to shift even if the locking member deforms due to the weight of the item.

[0019] Furthermore, in the glove for carrying transported goods of the present invention, the locking member or the second locking member may have a friction-enhancing portion formed on the wrist-side surface of the locking surface to improve frictional force. With this configuration, when a transporter holds a transported item such as a box, the friction-enhancing portion improves the frictional force between the transported item and the locking surface, making it less likely for the transported item to slip relative to the locking member. [Effects of the Invention]

[0020] According to the present invention, when carrying a heavy load, it is possible to provide gloves that can reduce the labor of the person carrying the load. Further, according to the present invention, when using a power assist suit, it is possible to provide gloves that reduce the labor of the hand and as a result, enable carrying a heavier load than before.

Modes for Carrying Out the Invention

[0022] Next, a glove 1 for carrying a load, which is an example of an embodiment of the present invention, will be described with reference to FIGS. 1 to 4. As shown in FIG. 1, the glove 1 for carrying a load in this embodiment has a main body 2 that covers the back of the hand and the palm, and a thumb part 3, an index finger part 4, a middle finger part 5, a ring finger part 6, and a little finger part 7 that cover each finger. The main body 2 is provided with a wrist part 8 that covers the wrist of the person wearing it.

[0023] In this embodiment, knitted fabric is used as the material of the glove 1 for carrying a load. Further, in this embodiment, the main body 2, the thumb part 3, the index finger part 4, the middle finger part 5, the ring finger part 6, and the little finger part 7 are integrally formed. Note that the fabric of the main body 2 may be not only knitted fabric but also other knitted or woven fabrics, or non-woven fabric, etc.

[0024] Furthermore, the cargo handling glove 1 of this embodiment has a rubber coating on the surface except for the wrist portion 8 of the main body 2. The rubber coating consists of a first coating 11 that is applied to the entire surface except for the wrist portion 8, and a second coating 12 that is further provided on the palm side. By providing the second coating 12 on the palm side of the first coating 11 in this way, the strength of the cargo handling glove 1 is improved.

[0025] Figure 1 schematically represents the skeletal structure of the wearer using dotted lines. Taking the ring finger as an example, from the fingertip, it consists of the distal phalanx A, middle phalanx B, proximal phalanx C, and metacarpal D. The bones on the wrist side of metacarpal D are omitted. The joint between distal phalanx A and middle phalanx B is the distal interphalangeal joint E, the joint between middle phalanx B and proximal phalanx C is the proximal interphalangeal joint F, and the joint between proximal phalanx C and metacarpal D is the metacarpophalangeal joint G. This is the same for all fingers except the thumb, where proximal phalanx C follows distal phalanx A.

[0026] In this embodiment, the glove 1 for carrying goods is provided with block-shaped locking members 13 on the palm side of the middle finger portion 5 and the ring finger portion 6. When a person puts their hand inside the glove 1 for carrying goods, the locking members 13 are provided between the location of the metacarpophalangeal joint G and the location of the proximal interphalangeal joint F of the fingers. In this embodiment, the locking members 13 are made of rubber, and multiple grooves 15 are formed on their surface in the width direction of the fingers, creating an uneven surface.

[0027] Figure 2 is a view of the cargo handling glove 1 shown in Figure 1, from the fingertip side. As shown in Figure 2, the locking member 13 is formed in a roughly fan shape along the surface when the middle finger portion 5 and ring finger portion 6 are made into a cylindrical shape. That is, the shape of the locking member 13 when viewed from the front is formed such that the arc length closer to the surface of the middle finger portion 5 and ring finger portion 6 is short, and the arc length further away from the surface is long.

[0028] Figure 3 is a cross-sectional view taken along line III-III in Figure 2. Referring to this figure, the locking member 13 is formed in a roughly fan-shaped cross-section. That is, the side cross-sectional shape of the locking member 13 is wider at the tip and narrows towards the finger side. Due to this shape, the angle R of the locking surface 14 on the palm side is formed to be acute with respect to the mounting surface. Also, as shown in Figure 3, in this embodiment, the locking member 13 is bonded to the second coating 12 using rubber adhesive so that it becomes one with the coating.

[0029] In this embodiment, the locking member 13 is formed to have a height of 1 / 5 to 4 / 5 of the outer diameter when the middle finger portion 5 or ring finger portion 6 is formed into a cylindrical shape. Specifically, as shown in Figure 3, if H is the outer diameter when the middle finger portion 5 or ring finger portion 6 is formed into a cylindrical shape, and h is the height of the locking member 13, then in this embodiment, the ratio is formed to be approximately 3 / 5.

[0030] In this embodiment, the material of the locking member 13 is a general rubber material used for coatings on general work gloves, etc. Any material can be used as the rubber material, such as natural rubber, synthetic rubber, or elastomer.

[0031] Referring to Figure 4, the operation of the locking member 13 when carrying a box T, which is the cargo, while wearing the cargo handling gloves 1 of this embodiment will be explained. Normally, when holding a box T while wearing the cargo handling gloves 1, the index finger is also placed on the box T, but in Figure 4, the index finger is extended so that the locking member 13 is visible.

[0032] As shown in Figure 4, when the glove 1 for carrying cargo of this embodiment is worn and the box T is held, the corners of the box T are locked by the locking member 13. The locking member 13 is held between the bottom of the box T and the fingers at the location of the middle phalanges B of the middle and ring fingers.

[0033] In this manner, when the locking member 13 is sandwiched between the bottom of the box T and the fingers at the location of the middle phalanges B of the middle and ring fingers, the corners of the box T are locked into the locking member 13. Therefore, unlike conventional anti-slip devices, the box T does not gradually slip and become difficult to hold, eliminating the need to change how the box T is held, and the box T can be easily transported.

[0034] Furthermore, in the glove 1 for carrying transported goods of this embodiment, a first coating 11 is applied to the part excluding the wrist portion 8, and a second coating 12 is applied to the palm side for reinforcement. A locking member 13 is provided on its surface, so that the locking member 13 is firmly fixed to the middle finger portion 5 and the ring finger portion 6.

[0035] Therefore, the angle R between the surfaces of the middle finger portion 5 and the ring finger portion 6 and the locking surface 14 of the locking member 13 is less likely to widen. In addition, the angle R of the locking surface 14 with respect to the mounting surface on which the locking member 13 is installed is formed at an acute angle. As a result, even if the locking member 13 deforms slightly when the box T is heavy, the bottom of the box T can be stably locked to the locking member 13.

[0036] Furthermore, as shown in Figure 4, even if the weight of box T causes the position of the transport glove 1 and the hand to shift during transport, the locking member 13 will stop at the distal interphalangeal joint E, and the locking member 13 will be sandwiched between the distal phalanx A and box T. The transporter can continue transporting box T in this state, or if transporting becomes difficult, they can put box T down temporarily.

[0037] Thus, the glove 1 for transporting goods according to this embodiment can reduce the effort required by the transporter when transporting goods. Furthermore, even when not transporting goods, the height of the locking member 13 is kept within 4 / 5 of the outer diameter when the finger portion is formed into a cylindrical shape, so there is less discomfort when gripping something.

[0038] Furthermore, when a carrier wears a power assist suit to transport goods, wearing the power assist suit makes it possible to transport heavier objects than anticipated. However, with the goods transport glove 1 of this embodiment, heavy objects can be easily transported even without relying on the grip strength of the hand, while maintaining the natural state of the hand.

[0039] Furthermore, when carrying items such as bags while wearing the carrying gloves 1 of this embodiment, the surface of the bag comes into contact with the locking surface 14 of the locking member 13. Therefore, even with such bags, they can be carried more easily compared to conventional work gloves.

[0040] Furthermore, in the glove 1 for transporting transported goods of this embodiment, multiple grooves 15 are formed on the surface of the locking member 13 in the width direction of the finger, creating an uneven surface. Therefore, in the case of transporting bagged goods, the frictional force with the transported goods increases due to this uneven surface, making it easier to transport the goods. Also, even if the transported goods are parts or other items with uneven surfaces, these uneven surfaces are locked by the locking surface 14 of the locking member 13, making them easy to transport.

[0041] In the above embodiment, locking members 13 are provided on both the middle finger portion 5 and the ring finger portion 6, but the invention is not limited to this, and may be provided on the surface of either one of the fingers. Furthermore, locking members 13 may be provided not only on the two fingers mentioned above, but also on the index finger portion 4 and the little finger portion 7.

[0042] Furthermore, in the above embodiment, the locking member 13 is formed in a substantially fan shape along the surface when the finger portion is made cylindrical, and its cross-sectional shape is also substantially fan-shaped, but the shape is not limited to this. The shape of the locking member 13 is such that when the carrier holds the transported object, the locking surface 14 is sandwiched between the transported object and the hand to lock the transported object. Also, the locking surface 14 does not have to be flat, and as long as it is a shape that can lock the transported object, it may have irregularities such as the second locking member 13a described later, or it may be arc-shaped or have other shapes.

[0043] In this embodiment, the block shape of the locking member 13 refers to a shape that differs from conventional small-diameter hemispherical anti-slip protrusions, having a locking surface 14 that rises from the surface of the finger portion, and is shaped so that the locking surface 14 can lock onto the transported object when the transported object is held.

[0044] On the other hand, the locking member 13 is not limited to a block shape, but may also be plate-shaped. In this case, it may have a locking surface 14 that rises from the surface of the finger, i.e., the installation point, and an L-shaped metal fitting or synthetic resin reinforcing member that extends from the base end of the locking surface 14 toward the base end of the finger, with the surrounding area coated with a rubber material. With such a configuration, the locking member 13 can be made into a thin plate shape, making it lighter and more compact.

[0045] Furthermore, in each of the above embodiments, the locking member 13 is bonded to the second coating 12 using rubber adhesive, but the invention is not limited to this, and the locking member 13 may be molded integrally with the second coating 12. Also, the coating may consist of one layer, or three or more layers, rather than just two layers as described above.

[0046] Furthermore, although the locking member 13 is made of rubber in the above embodiment, it is not limited to rubber and may be made of other materials such as synthetic resin. Also, a reinforcing member made of metal or synthetic resin may be provided inside the locking member 13. Furthermore, although the first coating 11 and the second coating 12 are made of rubber in the above embodiment, they are not limited to rubber and may be made of other materials such as synthetic resin.

[0047] Next, a second embodiment of the present invention, a glove for transporting transported goods 1a, will be described with reference to Figures 5 and 6. In the second embodiment, components having the same configuration as in the above embodiment are denoted by the same reference numerals in the drawings, and detailed descriptions are omitted.

[0048] In the second embodiment, the glove 1a for carrying goods has a second locking member 13a at a position different from that of the locking member 13 in the glove 1 for carrying goods of the first embodiment. In the second embodiment, the second locking member 13a is formed at a position between the distal interphalangeal joint E and the metacarpophalangeal joint G, as shown in Figure 5. More specifically, the second locking member 13a is provided such that at least a portion of it is located between the distal interphalangeal joint E and the metacarpophalangeal joint G.

[0049] Furthermore, as shown in Figure 6, the second locking member 13a has a friction-enhancing portion 14a formed on the wrist-side surface of the locking surface 14 to improve frictional force. As shown in Figure 6, this friction-enhancing portion 14a may have a wedge-shaped groove in cross-section, or conversely, a protrusion that projects toward the wrist. Alternatively, the friction-enhancing portion 14a may be formed by creating fine irregularities on the locking surface 14 to create a rough surface, or it may be formed by coating the locking surface 14 with a material that has a high coefficient of friction.

[0050] When carrying an object such as a box with the glove 1a equipped with the second locking member 13a, the corners of the object are locked in place by the second locking member 13a. The second locking member 13a is held between the bottom of the object and the fingers at the location of the distal phalanges A of the middle and ring fingers.

[0051] In this manner, when the second locking member 13a is sandwiched between the bottom of the transported object and the fingers at the location of the distal phalanges A of the middle and ring fingers, the corners of the transported object are locked to the second locking member 13a. Furthermore, since the second locking member 13a is provided with a friction-enhancing portion 14a on the locking surface 14, the frictional force between the transported object and the second locking member 13a is increased, making the transported object even less likely to slip. Therefore, unlike conventional anti-slip devices, the transported object does not gradually slip and become difficult to hold, eliminating the need to reposition the object, and allowing for easy transport of the object.

[0052] In the second embodiment, a friction-enhancing portion 14a is provided on the locking surface 14, but this friction-enhancing portion 14a may also be provided on the locking surface 14 of the locking member 13 in the above embodiment.

[0053] Furthermore, in each of the above embodiments, the locking member 13 and the second locking member 13a are provided on the middle finger portion 5 and the ring finger portion 6, but the invention is not limited to these, and they may be provided on other fingers, and the number is not limited to two. For example, the locking member 13 or the second locking member 13a may be provided at one location on the index finger portion 4, or the locking member 13 or the second locking member 13a may be provided on the four fingers excluding the thumb portion 3. Since the configuration of each of these examples is clear, illustrations are omitted. [Explanation of Symbols]
