Description

[Technical Field]

[0001] The present invention relates to a fingertip protector and a work glove. [Background technology]

[0002] Conventionally, for example, in heavy work sites where heavy objects must be held down or gripped, work gloves equipped with reinforcing members for protecting the fingers have been known to prevent accidents such as the fingertips colliding with or being pinched by the heavy object. For example, work gloves have been proposed in which the finger portions corresponding to the second to fifth fingers are covered with tubular reinforcing members (see Patent Document 1).

[0003] The work gloves in Patent Document 1 have reinforcing members made up of multiple tubes, allowing each finger to bend and stretch. However, because the tubular reinforcing members are present even on the pads of the fingers, the fingers come into contact with the work object via the reinforcing members, which impairs workability.

[0004] Therefore, finger protection members have been proposed as reinforcing members that cover parts other than the finger pads, and are attached to each finger to block the transmission of external forces to the fingers (see Patent Document 2).

[0005] However, when the load capacity of the reinforcing member in Patent Document 2 is set to, for example, about 1 ton, it must be manufactured using a fairly high-strength material with a large thickness, resulting in a problem of a heavy and bulky member. Also, with the structure in Patent Document 2, the first joint of the back of the finger comes into contact with the reinforcing member, which also causes a problem of impaired workability.

[0006] Furthermore, a protector that fixes multiple fingers has been proposed as an item with improved load-bearing capacity (see Patent Document 3). However, a structure in which multiple fingers are fixed together reduces workability. [Prior art documents] [Patent documents]

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the following description shows only one aspect of the present invention and can be modified as desired within the scope of the present invention. In each drawing, the same reference numerals indicate the same components, and their description will be omitted as appropriate. Note that the components shown in each drawing, i.e., the shape, size, thickness, relative positional relationship, etc. of each part, may be exaggerated for the purpose of explaining the present invention.

[0019] (Embodiment 1) FIG. 1 shows a perspective view of the fingertip protection equipment of the first embodiment, FIG. 2 shows a plan view and a front view thereof, and FIG. 3 shows a perspective view of work gloves fitted with these fingertip protection equipment.

[0020] As shown in these drawings, fingertip protection device 1 is a metal plate made of steel, stainless steel, or the like that is bent into a U-shape and includes two side plate portions 10 and a curved portion 20 connecting them. As shown in FIG. 3, this fingertip protection device 1 is used by being inserted over fingertips 101-105 of five fingers of a work glove 100. Each fingertip (not shown) is inserted into an internal space S between side plate portions 10 and curved portion 20 of fingertip protection device 1, with the tip of the fingertip positioned inside curved portion 20. As shown in FIGS. 1 and 2, each finger is inserted with the pad of the fingertip facing downward. FIG. 2(a) is a plan view (top view) of fingertip protection device 1 placed on a support surface in use, as viewed from above, and FIG. 2(b) is a front view viewed from the side where the fingertips are inserted.

[0021] Therefore, the width X of the space S, which is the distance between the two side plate portions 10, is set to be larger than the width of the fingertip, and the length Y, which is the distance between the end portion 11 of the side plate portion 10 opposite the curved portion 20 and the central inner surface 21 of the curved portion 20, is set to be larger than the length from the tip of the fingertip to the first joint and smaller than the length to the middle between the third joint and the second joint, and preferably smaller than the length to the second joint, and the height Z, which is the distance between the end faces 12, 22 on both sides of the side plate portion 10 and the curved portion 20, is set to be larger than the thickness of the fingertip.

[0022] If the width X is smaller than the width of the fingertip, the fingertip will not fit in, so it is set to be larger than the width of the fingertip. However, if it is too larger than the width of the fingertip, it may interfere with the fingertip protectors for other fingers, which could make it difficult to work, so the specified size is set taking these factors into consideration.

[0023] If the length Y is smaller than the length from the tip of the fingertip to the first joint, the height Z will be larger, making it more likely to fall over and potentially preventing the fingertip from being protected. Therefore, it is preferable to set the length Y larger than the length from the tip of the fingertip to the first joint. However, if the length Y is larger than the length between the third joint and the second joint, or if the length Y is larger than the length to the second joint, finger movement may be hindered, reducing workability. Therefore, it is preferable to set the length Y appropriately, taking these factors into consideration.

[0024] If the height Z is smaller than the thickness of the fingertip, the fingertip cannot be protected, so it is set to be larger than the thickness of the fingertip. However, if the height Z is too larger than the thickness of the fingertip, it may fall over easily, making it difficult to protect the fingertip, or may make it difficult to work with, so it is preferable to set the height Z taking these factors into consideration.

[0025] The width X, length Y, and height Z of such fingertip protector 1 may be set differently for each of the five fingertips, or there may be two types, one for the thumb and one for the other four fingers, or there may be three types, one for the thumb and one for the little finger, and one for the other three fingers, and there are no particular limitations. Figure 3 shows two sizes of fingertip protector, one for the thumb and one for the other fingertip protectors.

[0026] When fingertip protection device 1 of the present invention is placed on a flat support surface P with end surfaces 12, 22 facing downwards, side plate portions 10 and curved portions 20 are perpendicular to the support surface P. Here, when side plate portions 10 and curved portions 20 are flat, the surfaces of side plate portions 10 and curved portions 20 need only be perpendicular. However, when the surfaces are not flat, the centers of gravity of side plate portions 10 and curved portions 20 need only be oriented within end surfaces 12, 22.

[0027] In either case, when a heavy object H is placed on the fingertip protection device 1 placed on the support surface P and a load Q perpendicular to the support surface P is applied, the side plate portion 10 and the curved portion 20 simply become walls perpendicular to the load Q, thereby making the load-bearing capacity of the fingertip protection device 1 extremely high.

[0028] Furthermore, as described above, if a heavy load H is placed on the two side panels 10 and a force is applied from an oblique direction, the force acts in a direction that causes the side panels 10, which have become vertical walls, to fall. However, because the two side panels 10 are connected by the curved portions 20, the curved portions 20 act to resist the force that tends to cause the side panels 10 to fall, significantly increasing the load-bearing capacity. On the other hand, the arch-shaped finger protector described in Patent Document 2 does not ensure the load-bearing capacity of the arch-shaped roof member. Therefore, the roof member is first crushed. When the roof member is crushed, a force acts on the sides in a direction that opens to both sides (the direction of collapse), causing the two side panels to open, and therefore a large load-bearing capacity cannot be ensured. Furthermore, the crushed roof member may break into an M-shaped cross section, which may crush the fingertips, resulting in a risk of serious injury despite its use as a finger protector.

[0029] The fingertip protection device 1 of this embodiment has a simple shape, is lightweight and compact, yet has extremely high load-bearing capacity. In addition, since there are no components in the areas corresponding to the pad and back of the fingertip, workability is excellent.

[0030] In this embodiment, the side plate portion 10 and the curved portion 20 are integrally press-formed, but the side plate portion 10 and the curved portion 20 may be separate bodies and connected by welding or the like. Also, the side plate portions 10 located on both sides of the fingertip are parallel to each other, but they do not necessarily have to be parallel, and the side plate portions 10 may be slightly open in the direction of insertion of the fingertip.

[0031] Furthermore, in the above-described example, the vertical end faces 12 of the side plate portion 10 and the vertical end faces 22 of the curved portion 20 are continuously flush, but this is not necessarily limited to this, and the vertical dimension of the curved portion 20 may be gradually reduced toward the tip. In this case, the tip of the end face 22 of the curved portion 20 will be slightly raised above the support surface P, but this will not have a significant effect on the load-bearing performance.

[0032] In the above example, the end face 12 of the side plate 10 and the end face 22 of the curved portion 20 are perpendicular to the surfaces of the side plate 10 and the curved portion 20, but this is not necessarily limited to this. As shown in FIG. 4, the side plate 10A may have an end face 12A that is curved when viewed from the front, and the curved portion 20 may have a curved end face 22A. However, when placed on a support surface P, most of the end faces 12A, 22A of the side plate 10A and the curved portion 20A must be in contact with the support surface P, and the side plate 10A and the curved portion 20A must be perpendicular to the support surface P. In this case, the larger the contact area between the support surface P and the end faces 12A, 22A, the better the load-bearing capacity, so the end faces 12, 22 that are perpendicular to the surface are preferred.

[0033] (Embodiment 2) FIG. 5 shows a perspective view of a fingertip protection device according to the second embodiment. As shown in the figure, fingertip protection device 1B of this embodiment has chamfered portions 15 on both the upper and lower sides of the end of side plate portion 10B opposite curved portion 20. Since other points are the same as those of embodiment 1, the same reference numerals are used and redundant explanations are omitted.

[0034] In this embodiment, the chamfered portion 15 is a rounded surface, but it may be a sloped surface. The chamfered portion 15 is provided on the pad side of the fingertip in particular, which has the effect of improving workability. Therefore, although the chamfered portion 15 may be provided only on the pad side of the fingertip, in this embodiment, the chamfered portion 15 is provided on both the top and bottom sides because the same effect can be obtained even if the chamfered portion 15 is used upside down.

[0035] When chamfered portion 15 is provided, as shown in FIG. 2, the contact area between support surface P and end face 12 when the device is placed on support surface P is reduced, which may have some effect on the load-bearing performance. Therefore, the size of chamfered portion 15 may be determined by balancing the improvement in operability with the effect on load-bearing performance, and the size of chamfered portion 15 should be no more than 1 / 3, preferably no more than 1 / 4, of the length of end face 12 of side plate portion 10B.

[0036] (Embodiment 3) FIG. 6 shows a perspective view of a fingertip protection device according to the third embodiment. As shown in the figure, the fingertip protection device 1C of this embodiment has a curved portion 20, a part of the side plate portion 10 on the curved portion 20 side, and an upper plate portion 30 that covers the space between them.Other aspects are the same as in embodiment 1, so the same symbols are used and redundant explanations will be omitted.

[0037] In this embodiment, the upper plate portion 30 is integrally formed by press molding together with the side plate portions 10 and the curved portion 20, but it may be formed as a separate member and joined by welding or adhesive. Furthermore, the upper plate portion 30 may be formed as a separate member and made detachable.

[0038] The upper plate portion 30 is intended to protect the fingertips from collision with objects smaller than the spacing between the side plate portions 10. However, since the upper plate portion 30 comes into contact with the joint of the back of the finger when bending the fingertip, it must be provided with workability in mind. The maximum length Y1 of the upper plate portion 30 should be shorter than the length from the tip of the fingertip to the first joint, preferably the length to the first joint. The upper plate portion 30 may be provided so as not to cover the distal end side of the bending portion 20 .

[0039] (Other embodiments) The above-described embodiment is an example of a preferred mode, but the present invention is not limited to this and can be implemented with some modifications. The material of fingertip protection device 1 is not limited to metal, and may be selected as needed. For example, fingertip protection device 1 may be molded by pressure molding with heating or injection molding using synthetic resins such as polycarbonate, PC alloy (copolymer resin of polycarbonate and PBT resin, etc.), ABS, PET, which have excellent impact resistance and ease of molding, or polypropylene, nylon, etc., which preferably have excellent chemical resistance. Furthermore, fiber reinforced plastic (FRP), which is made by adding fibers such as glass fiber to the above-mentioned resins, may also be used.

[0040] The material of the fingertip protection equipment 1 can be, for example, a metal plate in a site where a high load capacity is required, or a synthetic resin in a case where a low load capacity is acceptable. Furthermore, since the shape of the synthetic resin can be freely selected depending on the material, the thickness and shape can be changed according to the required strength and function.

[0041] FIG. 7 shows plan views of various fingertip protection devices. 7(a) is provided with a plurality of reinforcing beams 41 extending in the Z direction on the inside of the curved portion 20D. This improves the load-bearing capacity of the curved portion 20D, making it stable and less likely to tip over, and improving the overall load-bearing capacity. A fingertip protection member 1E in FIG. 7(b) is provided with a thick portion 42 on the distal end side of a curved portion 20E, which improves the overall load resistance. The fingertip protection device 1F in Figure 7(c) has a bent portion 43 at the end of the curved portion 20F on the side plate portion 10 side, which increases the length of the curved portion 20F and makes it stable and less likely to tip over, thereby improving the overall load-bearing capacity. The fingertip protection device 1G in Figure 7(d) has a shape in which a bent portion 44 is provided continuously in the thickness direction of the entire curved portion 20G, which increases the length of the curved portion 20G and makes it stable and less likely to tip over, thereby improving the overall load-bearing capacity. The fingertip protection device 1H in Figure 7(e) has a bent portion 45 that is continuous with the side plate portion 10H, which increases the length of the side plate portion 10H and makes it stable and less likely to tip over, thereby improving the overall load-bearing capacity. The fingertip protection device 1I in Figure 7(f) has a curved portion 20I with an expanded portion 46 that is larger than the width of the side plate portion 10 in the X direction. This increases the length of the curved portion 20I, makes it stable and less likely to tip over, and improves the overall load-bearing capacity.

[0042] For example, the inner surfaces (surfaces that come into contact with the fingertips) of the curved portion 20 and the side plate portion 10 may be provided with lining materials made of rubber, elastomer, felt, fleece, etc. This protects the fingertips when they come into contact with the surface and improves the feel when used.

[0043] The lining material is preferably provided on at least the inner surface of the curved portion 20, and may be provided continuously on the inner surface of the side plate portion 10. Also, it may be provided on the inner surface of the upper plate portion 30.

[0044] Furthermore, the outer surfaces (surfaces that come into contact with gloves) of the curved portion 20 and the side plate portion 10 may be provided with lining materials such as rubber, elastomer, felt, or fleece. This softens the contact with the gloves and also softens the contact with the work object through the gloves, improving the feeling when using the gloves.

[0045] Furthermore, for example, a convex portion may be provided on the outer surface of the curved portion 20 (the surface that comes into contact with the glove). An example of this is shown in Fig. 8. Fig. 8(a) is a plan view of fingertip protection equipment 1J, and Fig. 8(b) is a side view, in which a convex portion 47 is provided on the tip side of the curved portion 20J. This allows small buttons and switches to be pressed even while wearing gloves.

[0046] Furthermore, for example, protrusions may be provided on the inner surface (surface that comes into contact with the finger) of the curved portion 20 or the side plate portion 10K. Fig. 9 is a plan view of such a fingertip protection device 1K, in which a ridge 48 extending in the Z direction is provided on the inside near the end of the side plate portion 10K. This allows the ridge 48 to come into contact with the first and second joints of the fingertip, making it difficult for the fingertip protection device to slip off the finger.

[0047] Furthermore, for example, protrusions may be provided on the curved portion 20 or the outer surface of the side plate portion 10 (the surface that comes into contact with the glove). Fig. 10 is a plan view of such a fingertip protection device 1L, in which a ridge 49 is provided on the outer side near the end of the side plate portion 10L, protruding outward in the X direction and extending in the Z direction. This allows the ridge 49 to be caught in the knitting of the glove, making it difficult for the fingertip protection device to slip off the glove. Note that a protrusion may be provided instead of the ridge 49, and multiple protrusions may be provided along the Z direction.

[0048] Furthermore, for example, the fingertip protector of the present invention may be used in gloves or in five-finger socks as a toe protector, thereby protecting the toes.

[0049] (Example) Two types of fingertip protectors with the shape shown in Figure 1 were manufactured: one for the thumb and one for the other fingers. For the thumb, a steel plate 30 mm wide and 92 mm long was curved to form a fingertip protector with dimensions of X=26 mm, Y=37 mm, and Z=30 mm. For other fingers, a steel plate 20 mm wide and 73 mm long was curved to form a fingertip protector with dimensions of X=20 mm, Y=29 mm, and Z=20 mm.

[0050] (Comparative Example) Using the same material as in the example, arch-shaped fingertip protectors as shown in FIG. 11 were molded in dimensions for the thumb and other fingers. For the thumb, a steel plate 30 mm wide and 54 mm long was curved to form a fingertip protector with dimensions of x=26 mm, y=30 mm, z=18 mm. For the other fingers, a steel plate 30 mm wide and 45 mm long was curved to form a fingertip protector with dimensions of x = 20 mm, y = 30 mm, z = 15 mm.

[0051] (Test example) The fingertip protection devices of the examples and comparative examples were placed on the base, and a load was applied in the vertical direction, and the load at which they broke was taken as the withstand load. The results are shown in Table 1, and it was confirmed that the fingertip protection device of the example had significantly greater load-bearing capacity than the arch-shaped device.

[0052] [Table 1] [Industrial Applicability]

[0053] The fingertip protectors and work gloves of the present invention are useful not only as gloves for heavy work but also as gloves for delicate work requiring the use of fingertips.Furthermore, they can also be used for five-finger socks. [Explanation of symbols]
