Description

[Technical field]

[0001] The present invention relates to a tool bag that is hung from a worker's waist for carrying tools and the like. [Background technology]

[0002] Traditionally, at work sites, etc., waist pouches that are hung from the waist are used to store and carry tools (tools, small items, and equipment) used during work. Most of these waist pouches are of the type that are attached to the waist belt of trousers, etc., and have a storage section for storing tools, etc., and a belt loop section.

[0003] For example, Patent Documents 1 and 2 each disclose a waist bag in which a waist belt is inserted into a belt loop formed by sewing (welding or riveting) both ends of a belt-shaped member. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Publication No. 01-114287 [Patent Document 2] JP 2018-134715 A Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned waist bag is attached by inserting the waist belt through the loop-shaped belt loop, so it is difficult to come off during work. However, on the other hand, when attaching it, it is necessary to pass the waist belt through the belt loop, and when removing it, it is necessary to pull the waist belt out of the belt loop. In other words, there is a problem that attaching and removing the above-mentioned waist bag is not easy and takes a lot of time. The object of the present invention is to provide a waist bag that is difficult to come off during work and can be easily attached and detached to the waist belt. [Means for solving the problem]

[0006] The waist bag of the present invention is hung from a waist belt worn around the waist of a worker, A bag-shaped storage section having an opening; a belt attachment member that is folded in two and plastically deformed and connected to an upper side of the storage portion; A first magnetic body attached to an outer surface of the storage portion; A second magnetic body attached to the belt attachment member; Equipped with The belt attachment member has a belt receiving portion that is hooked onto the waist belt, and a long belt insertion portion that is inserted between the waist belt and the worker, When the belt attachment member is folded, the belt insertion portion covers a part of the outer surface of the storage portion in a flap shape, and at least a part of the first magnetic body and the second magnetic body face each other, The belt insertion portion is characterized in that the first magnetic body and the second magnetic body are attracted to each other by magnetic force, thereby being fixed to the storage portion.

[0007] Generally, there are many types of waist bags that are attached to a waist belt by inserting the waist belt through a loop (annular or cylindrical) belt loop. These waist bags may need to be attached and removed repeatedly several times throughout the day, such as when traveling by car or on foot, when entering a restaurant, etc., and when resuming work. However, the above-mentioned conventional waist bags require attachment and removal from the waist belt, so that attachment and removal are time-consuming. According to the configuration of the present invention, when attaching, the belt insertion part is inserted between the worker and the waist belt, the belt receiving part is hooked on the waist belt, and then the first magnetic body and the second magnetic body are attracted by magnetic force to be fixed, so that attachment is easy. In addition, when removing, the first magnetic body and the second magnetic body are separated by simply pulling the storage part or the belt insertion part upward, and the waist bag can be easily removed. In this way, a waist bag that can be easily attached and removed even with one hand without extra time or effort can be realized.

[0008] In addition, the present invention has a structure in which the first magnetic body and the second magnetic body are attached to the storage section and the belt attachment member, which are made of a material with a relatively high rigidity, respectively. For example, if the storage section or the belt attachment member has low rigidity, they are easily deformed (easily twisted) by external forces, etc., and the first magnetic body and the second magnetic body are easily displaced, which may result in poor fixation between the belt attachment member and the storage section. Therefore, with the above configuration, the relative positions of the first magnetic body and the second magnetic body are less likely to shift when attaching the waist bag, and fixation of the belt attachment member and the storage section is stabilized.

[0009] In addition, in the present invention, the belt receiving portion is plastically deformed in a state where it is folded in two. If the belt receiving portion on which the waist belt is hooked is not plastically deformed, stress due to the weight of the waist bag or the like is applied to various parts of the belt attachment member, and the first and second magnetic bodies that are attracted to the belt attachment member may easily separate. If the belt receiving portion on which the waist belt is hooked is not plastically deformed, the place where the waist belt is hooked is different each time, and there is a risk that the fixation of the belt attachment member and the storage portion (the first and second magnetic bodies) may become unstable. On the other hand, by plastically deforming the belt receiving portion in a state where it is folded in two, it is possible to suppress the application of unnecessary stress to the first and second magnetic bodies, and to make them less likely to come off. Furthermore, according to the above configuration, the place where the waist belt is hooked when attaching is approximately the same position each time, so that the fixation of the belt attachment member and the storage portion is stabilized. Effect of the Invention

[0010] According to the present invention, it is possible to realize a waist bag that is difficult to come off during work and can be easily attached to and detached from a waist belt. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, several specific examples will be given with reference to the drawings to show a number of embodiments for carrying out the present invention. In each drawing, the same reference numerals are given to the same parts. For the sake of convenience, the embodiments are shown separately in consideration of the ease of explanation or understanding of the main points, but partial replacement or combination of the configurations shown in different embodiments is possible. In the second and subsequent embodiments, the description of matters common to the first embodiment will be omitted, and only the differences will be described. In particular, similar actions and effects due to similar configurations will not be mentioned in each embodiment. Note that in each drawing (FIG. 2(B), FIG. 5(A), FIG. 5(B), FIG. 6(A) and FIG. 6(B)), the length, thickness, etc. of each part are shown exaggerated and may not match the actual dimensions. This also applies to each drawing in each of the following embodiments.

[0013] The "waist bag" of the present invention is a waist bag that has a storage section for storing props, tools, etc., and is attached to and hung from the waist belt of a worker's trousers, etc. The "waist bag" of the present invention is, for example, a scissor case for a barber or hairdresser, or a portable storage device for a tradesman (electrical contractor, remodeler, plumber, etc.) to carry a scale, cutter, magic marker, etc. The waist bag according to the first embodiment is a small bag made of leather with relatively high rigidity, and a belt attachment member made of a flat plate plastically deformed into a U-shape or V-shape is attached to the upper back side. The belt attachment member has a long, tapered belt insertion section that is inserted between the waist belt and the worker when attaching the waist bag. When the belt attachment member is folded in half, the belt insertion section and the storage section (base member) face each other. A first magnetic body and a second magnetic body are attached to the portions where the belt insertion section and the storage section face each other, respectively. When attaching, the first magnetic body and the second magnetic body are attracted to each other by magnetic force, and the vicinity of the tip of the belt insertion part is fixed to the outer surface of the storage part, forming a loop between the belt attachment member and the storage part. Since the vicinity of the tip of the belt insertion part and the outer surface of the storage part are fixed by magnetic force, it is easy to attach and detach from the waist belt.

FIG. 7 is a front view of the waist bag 1. FIG. 8 is a rear view of the waist bag 1. FIG. 9 is a plan view of the waist bag 1. FIG. 10 is a bottom view of the waist bag 1. Fig. 11 is a right side view of the waist bag 1. Fig. 12 is a left side view of the waist bag 1.

[0015] The waist bag 1 includes a storage section 2, a belt attachment member 3, a first magnetic body G1, a second magnetic body G2, etc. In this specification, the +Z direction is the upper side of the waist bag, the -Z direction is the lower side, the +Y direction is the back side, the -Y direction is the front side, and the X-axis direction is the side.

[0016] The storage section 2 is a bag- or box-shaped member having an opening 21 formed on the upper side (a portion located on the +Z direction side of 1 / 2 the height in the Z-axis direction) and side openings 22 formed on the sides (portions located in the X-axis direction). The storage section 2 has a base member 11, a cover member 12, partition members 13, 14, and the like. The base member 11 is a member that abuts (or is close to) an operator when mounting, and is a flat plate having a trapezoidal planar shape. The cover member 12 is a flat plate having a T-shape planar shape, and is a member that is attached to the front side (-Y direction side) of the base member 11 by riveting or sewing in a folded state. As shown in FIG. 2(A) and FIG. 2(B), etc., by mounting the cover member 12 to the front side of the base member 11, the elliptical opening 21, the two substantially semicircular side openings 22, and the storage space 6 are formed. The partition members 13, 14 are both disposed in the storage space 6. The partition member 13 is a flat plate having a rectangular planar shape, and is attached to the surface S1 of the base member 11 in a state where it is bent into a substantially M-shape. The partition member 14 is a flat plate having a rectangular planar shape, and is attached to the surface of the partition member 13. As shown in Figs. 2(A) and 2(B), etc., by attaching the partition member 13 to the surface S1 of the base member 11, two teardrop-shaped openings 23 and two storage spaces 7 are formed. In addition, by attaching the partition member 14 to the surface of the partition member 13, an approximately semicircular opening 24 and a storage space 8 are formed. The material of the base member 11, the cover member 12, and the partition members 13 and 14 is, for example, 4 mm thick tanned cowhide.

[0017] The belt attachment member 3 is a member obtained by bending a long flat plate in two (into a U-shape or V-shape) and plastically deforming it. The belt attachment member 3 has a belt insertion section 31 and a belt receiving section 32. As shown in FIG. 2(B) and other figures, one of the folded parts of the belt attachment member 3 is connected to the upper side of the outer surface (the back surface S2 of the base member 11) of the storage section 2 by riveting and sewing. The belt insertion section 31 is the other folded part, and as shown in FIG. 2(B) and FIG. 6(A) and other figures, is a long part that is inserted between the waist belt 50 and the worker 40 when the worker attaches it. In addition, the surface PS1 of the belt insertion section 31 is the surface that actually abuts against the worker when attaching it. The belt receiving section 32 is a part of the belt attachment member 3 that is plastically deformed in a folded state and is a part that is hooked onto the waist belt 50. The material of the belt attachment member 3 is, for example, 4 mm thick tanned cowhide.

[0018] As shown in FIG. 2(B) and FIG. 3, the belt insertion part 31 covers a part of the storage part 2 in a state where the belt attachment member 3 is folded (it hangs down in a flap shape so as to overlap the back surface S2 of the base member 11 when viewed from the Y-axis direction). The planar shape of the belt insertion part 31 is a "tapered shape" in which the width is wide on the belt receiving part 32 side and narrows as it approaches the tip (moves in the -Z direction). In addition, the belt insertion part 31 has a relatively high rigidity so that it does not bend easily, so that it can be easily inserted between the waist belt 50 and the worker 40. Specifically, the belt insertion part 31 according to this embodiment has a structure in which two flat plates are bonded together with a 1.5 mm thick reinforcing polyethylene terephthalate plate (specific gravity 1.27) sandwiched in the middle (not shown).

[0019] The first magnetic body G1 is a round magnetic body and is attached to the lower side (a portion located on the -Z direction side of 1 / 2 the height in the Z-axis direction) of the outer surface (back surface S2 of the base member 11) of the storage section 2. The second magnetic body G2 is a flat magnetic body with a rectangular planar shape and is attached near the tip of the back surface PS2 of the belt insertion section 31. As shown in FIG. 3 and FIG. 5(A), when the belt attachment member 3 is fixed to the storage section 2 (when the belt attachment member 3 is folded), at least a portion of the first magnetic body G1 and the second magnetic body G2 face each other. The first magnetic body G1 is, for example, a round neodymium magnet (axial magnetization. Maximum vertical load on the axis is 10 kg, 200 mT or more) with a diameter of 20 mm and a height of 6 mm. The second magnetic body G2 is, for example, a rectangular (13 mm x 43 mm) iron plate.

[0020] The first magnetic body G1 and the second magnetic body G2 are attracted to each other by magnetic force, and the belt insertion section 31 is fixed to the storage section 2. That is, the first magnetic body G1 and the second magnetic body G2 are attracted to each other by magnetic force, and a loop (belt loop section) is formed by the storage section 2, the belt attachment member 3, the first magnetic body G1 and the second magnetic body G2. When the belt insertion section 31 and the storage section 2 are fixed, the gap D1 in the thickness direction of the portion that clamps the waist belt (for example, the gap in the Y-axis direction of the portion that clamps the waist belt in FIG. 5) is 10 mm.

[0021] The actual dimensions of the utility bag 1 are a depth (length in the Y-axis direction) of 115 mm, a width L1 (length in the X-axis direction) of 125 mm, and a height (length in the Z-axis direction) of 195 mm, a height H2 of the cover member 12 of the storage section 2 of 148 mm, and a height of the base member 11 of 190 mm. The width L2 (length in the X-axis direction) of the belt receiving section 32 is 100 mm, and the length H1 (height in the Z-axis direction) from the belt receiving section 32 to the bottom of the utility bag 1 is 185 mm. Furthermore, the length H3 of the loop (the length from the belt receiving section 32 to the part where the first magnetic body G1 and the second magnetic body G2 come into contact when attached) is 125 mm, the height of the belt inserting section 31 in the Z-axis direction is 168 mm, and the width L3 of the tip of the belt inserting section 31 is 50 mm.

[0022] Next, a method for attaching and detaching the waist bag 1 of the present invention will be briefly described.

[0023] 6(A), when the waist bag 1 is attached to the waist belt 50, the first magnetic body G1 and the second magnetic body G2 are attracted by magnetic force, and the belt attachment member 3 is fixed to the base member 11 of the storage section 2. At this time, the belt attachment member 3 (the surface of the belt insertion section) abuts against the buttocks 41 of the worker 40.

[0024] When attaching the waist bag 1, as shown in FIG. 6(B), the belt insertion portion 31 of the belt attachment member 3 is inserted between the waist belt 50 and the worker 40 from above to below (-Z direction) with the first magnetic body G1 and the second magnetic body G2 separated. When the belt insertion portion 31 is inserted all the way through, the waist belt 50 is caught in the belt receiving portion 32. Then, by bringing the storage portion 2 (base member 11) closer to the belt insertion portion, the waist belt 50 is clamped by the bent belt attachment member 3. Then, the first magnetic body G1 and the second magnetic body G2 are attracted to each other by magnetic force, and the belt insertion portion 31 is fixed to the base member 11.

[0025] Conversely, when removing the waist bag 1, the waist bag 1 can be easily pulled out by pulling the storage section 2 or the belt attachment member 3 upward (in the +Z direction). Specifically, by pulling the waist bag 1 upward, the first magnetic body G1 and the second magnetic body G2 that have been attached by magnetic force are caught on the waist belt 50 and separated, and the fixed storage section 2 and the belt attachment member 3 are released. Note that before pulling the waist bag 1 upward, the storage section 2 may be lifted in the -Y direction to separate the first magnetic body G1 and the second magnetic body G2 first.

[0026] The waist bag 1 according to this embodiment has the following advantages.

[0027] (a) In general, most of the waist bags that are hung on a waist belt are of the type that are attached by inserting the waist belt through a loop (annular or cylindrical) belt loop. These waist bags may need to be attached and removed repeatedly several times throughout the day, such as when moving by car or on foot, when entering a restaurant, etc., and when resuming work. However, the above-mentioned conventional waist bags require attachment and removal from the waist belt, which is a problem in that it takes time and effort to attach and remove them. The waist bag 1 of the present invention is easy to attach because it can be fixed simply by inserting the belt insertion part 31 between the worker 40 and the waist belt 50, hooking the belt receiving part 32 on the waist belt 50, and then attracting the first magnetic body G1 and the second magnetic body G2 with magnetic force. In addition, when removing the waist bag, the first magnetic body G1 and the second magnetic body G2 can be separated by simply pulling the storage part 2 or the belt insertion part 31 upward, and the waist belt can be easily removed. Thus, according to the present invention, attachment and detachment can be easily performed with one hand without requiring extra time or effort.

[0028] There are also waist bags that are fastened with buttons or hook-and-loop fasteners to form loops, but since it is necessary to fasten the buttons or hook-and-loop fasteners when attaching them and to remove them, it is necessary to use both hands. Furthermore, in the case of buttons and hook-and-loop fasteners, there is a risk that the material may deteriorate or break due to repeated use, and the fastening force may decrease. On the other hand, according to the present invention, the storage section 2 and the belt attachment member 3 are fixed by the magnetic force of the first magnetic body G1 and the second magnetic body G2, so there is a low possibility of deterioration or damage due to repeated use. In other words, it is possible to realize a waist bag that can be easily attached and removed with one hand and whose fastening force (between the belt attachment member 3 and the storage section 2) is unlikely to decrease even with repeated use.

[0029] The waist bag 1 of the present invention has a structure in which the first magnetic body G1 and the second magnetic body G2 are attached to the storage section 2 and the belt attachment member 3, which are made of a material with a relatively high rigidity. For example, if the rigidity of the storage section 2 and the belt attachment member 3 is low, they are easily deformed (twisted) by external forces, etc., and the first magnetic body G1 and the second magnetic body G2 are easily displaced, which may cause problems in fixing the belt attachment member 3 and the storage section 2. In other words, the first magnetic body G1 and the second magnetic body G2 may not face each other, and the first magnetic body G1 and the second magnetic body G2 may not be attracted by magnetic force. Therefore, this configuration makes it difficult for the first magnetic body G1 and the second magnetic body G2 to be displaced relative to each other when the waist bag is attached, and the fixation of the belt attachment member 3 and the storage section 2 is stabilized. Note that "relatively high rigidity (strength)" means that the bending rigidity (or strength) is higher than, for example, soft polyvinyl chloride (soft PVC) or a 3 mm thick polyvinyl chloride plate.

[0030] In addition, in the present invention, the belt receiving portion 32 is plastically deformed in a state where it is folded in two. If the belt receiving portion 32 on which the waist belt 50 is hooked is not plastically deformed, stress due to the weight of the waist bag or the like is applied to various parts of the belt attachment member 3, and the first magnetic body G1 and the second magnetic body G2 that are attracted to the belt attachment member 3 may easily come off. In addition, if the belt receiving portion 32 on which the waist belt 50 is hooked is not plastically deformed, the part where the waist belt 50 is hooked may be different each time, and the fixing force between the belt attachment member 3 and the storage portion 2 (the first magnetic body G1 and the second magnetic body G2) may vary, and the fixation may become unstable. On the other hand, according to the present invention, since the belt receiving portion 32 is plastically deformed in a state where it is folded in two, it is possible to suppress the application of unnecessary stress to the first magnetic body G1 and the second magnetic body G2, and it is possible to make them less likely to come off. Furthermore, with this configuration, the waist belt 50 is hooked at approximately the same position every time it is attached, so that the fixation of the belt attachment member 3 and the storage section 2 is stable.

[0031] (b) In the waist bag 1 of the present invention, the belt insertion portion 31 has a relatively high strength (rigidity), so that when attaching the waist bag 1, it is easy to insert it between the worker 40 and the waist belt 50. In addition, in the waist bag 1 of the present invention, the entire belt attachment member 3 (the belt insertion portion 31 and the belt receiving portion 32) has a relatively high strength (rigidity). If the strength (rigidity) of the belt attachment member 3 is low, the belt attachment member 3 may be deformed by the weight of the waist bag, etc. (the waist bag itself, the tools stored in the storage portion 2, etc.), and an excessive load may be applied between the fixed first magnetic body G1 and the second magnetic body G2, causing the waist bag to fall off the waist belt 50. Therefore, by increasing the strength (rigidity) of the belt attachment member 3, the fixation between the storage portion 2 and the belt attachment member 3 can be stabilized, and the waist bag can be prevented from falling off during work. The load capacity of the belt receiving portion 32 of the waist bag 1 according to this embodiment was about 10 kg. The rigidity (bending rigidity) or strength of the belt insertion portion 31 is higher than that of, for example, soft polyvinyl chloride (soft PVC) or a 3 mm thick polyvinyl chloride plate.

[0032] (c) The belt insertion part 31 of this embodiment has a "tapered shape" in which the width narrows toward the tip, so that the belt insertion part 31 can be easily inserted between the waist belt 50 and the worker 40 compared to a shape in which the width widens toward the tip. In this embodiment, the belt insertion part 31 is illustrated as having a flat shape in which a sword shape is combined with the end of the upper side (short side) of a trapezoid, but the "tapered shape" is not limited to this. In this specification, the "tapered shape" refers to a tapered shape in which the width narrows from the base toward the tip. In other words, even if the belt insertion part 31 has a shape such as a triangle or a trapezoid, or a shape combining two or more figures (for example, a shape obtained by adding a triangle to a rectangle), if the width roughly narrows toward the tip, it is called a "tapered shape". Conversely, if there is a portion in which the width becomes wider toward the tip, it is not called a "tapered shape". The belt insertion section 31 does not necessarily have to be tapered, and may have a portion that becomes wider toward the tip, but in that case, there is a risk that it may get caught on the waist belt 50 when attaching it. Therefore, the belt insertion section 31 is preferably tapered.

[0033] (d) The material of each part of the waist bag 1 (base member 11 and belt attachment member 3) is cowhide (tanned leather, 4 mm thick). By using a material that is relatively rigid and can be plastically deformed for each part of the waist bag, it is possible to realize a waist bag that achieves the functions and effects of the present invention without using additional reinforcing members, etc.

[0034] (e) In this embodiment, the vertical strength and vertical load in the axial direction of the first magnetic body G1 and the second magnetic body G2 (load capacity in the Z-axis direction) is 10 kg, and the tensile strength in the axial direction (load capacity in the Y-axis direction) is 8 kg. In this way, the attracted first magnetic body G1 and second magnetic body G2 do not easily separate in the axial direction (Y-axis direction) or the direction perpendicular to the axial direction (Z-axis direction), so the fixation between the belt attachment member 3 and the storage section 2 during work is stable and does not easily come off.

[0035] (f) In addition, in the case of a waist bag in which the storage section 2 and the belt attachment member 3 are fastened with buttons or hook-and-loop fasteners to form a loop, once the waist bag comes off, it will not be fastened again unless it is fastened again manually. On the other hand, in the present invention, the storage section 2 and the belt attachment member 3 are fastened by the magnetic force of the first magnetic body G1 and the second magnetic body G2, so even if the fastening between the storage section 2 and the belt attachment member 3 comes off due to some accident (vibration, shaking, etc.) during use, the fastening will be re-fastened when the first magnetic body G1 and the second magnetic body G2 come close to each other. Therefore, it is possible to realize a waist bag 1 that is difficult to fall off the waist belt 50.

[0036] (g) If the gap D1 in the thickness direction of the portion that clamps the waist belt is too large, there is a risk that the vibration and shaking will become large when the worker is walking or working. On the other hand, in this embodiment, the gap D1 in the thickness direction of the portion that clamps the waist belt when the belt insertion section 31 and the storage section 2 are fixed is 5 mm or more and 20 mm or less. With this configuration, when the waist belt 50 is thick, the belt attachment member 3 clamps the waist belt 50. Also, with this configuration, even when the waist belt 50 is thin, the gap between the belt attachment member 3 and the waist belt 50 is narrow. Therefore, with this configuration, the vibration and shaking of the waist bag 1 when attached to the waist belt 50 is suppressed.

[0037] (h) If the width (length in the X-axis direction) of the belt receiving portion 32 that contacts the waist belt 50 and its vicinity is narrow, the waist bag 1 attached to the waist belt 50 is likely to become unstable, and vibration and shaking may increase when the worker walks or works. On the other hand, in this embodiment, the width L2 of the belt receiving portion 32 and its vicinity is 60 mm or more (3 / 5 or more of the width L1 of the waist bag 1). By widening the width of the belt receiving portion 32 and its vicinity, vibration and shaking of the waist bag 1 attached to the waist belt 50 are suppressed. However, while the human waist is curved, the belt receiving portion 32, which has high rigidity, is difficult to deform. In particular, if the width of the belt receiving portion 32 is too wide, discomfort is noticeable when attached to the waist belt 50. In addition, if the width of the belt receiving portion 32 is wide, a large load (bending) is applied to the belt receiving portion 32 when attached, and durability is also reduced. Therefore, in order to reduce discomfort when attached and to improve durability, the width of the belt receiving portion 32 and its vicinity is preferably 125 mm or less (less than the width L1 of the waist bag 1). In this specification, "the vicinity of the belt receiving portion 32" refers to a portion of the belt insertion portion 31 up to 50 mm away from the point where the waist belt 50 is actually hooked.

[0038] (i) In this embodiment, the loop length H3 (the length from the belt receiving portion 32 to the portion where the first magnetic body G1 and the second magnetic body G2 are in contact) when the waist bag 1 is attached is 50 mm or more (or is 1 / 3 or more of the height of the waist bag 1 in the Z-axis direction). If the loop length H3 is long, the waist bag 1 can be attached to a wide waist belt 50. If the loop length H3 is long, the gap (play) is also large, so even if the waist bag 1 shakes or receives a shock, it is absorbed by the gap and is difficult to come off. More preferably, the loop length H3 is 100 mm or more. However, if the loop length H3 is too long, it becomes difficult for the worker to remove the waist bag 1. Therefore, the loop length H3 is preferably 200 mm or less (or 4 / 5 or less of the height of the waist bag 1 in the Z-axis direction).

[0039] (j) If the length from the belt receiving portion 32 to the bottom of the waist bag 1 is too long, the waist bag 1 may hit the thighs or the like when the worker 40 walks, and become an obstacle. Also, if the worker sits down with the waist bag 1 attached, the storage portion 2 may hit the floor or the like and be pushed up, causing the waist bag 1 to come off. In this embodiment, the length from the belt receiving portion 32 to the bottom of the waist bag 1 (length in the Z-axis direction) is short, at 200 mm or less, so that the waist bag 1 is unlikely to get in the way of walking and is unlikely to come off even if the worker sits down with the waist bag attached. In this embodiment, the second magnetic body G2 is attached near the tip of the belt insertion portion 31. With this configuration, the loop length H3 (gap) can be increased without making the length from the belt receiving portion 32 to the bottom of the waist bag 1 longer than necessary.

[0040] (k) In the waist bag 1 according to the present embodiment, two side openings 22 are formed on the lower side of the side of the storage section 2. This configuration can prevent dust and the like from accumulating in the storage space 6 of the storage section 2. In the present embodiment, the storage section 2 is shown with one side opening 22 formed on each of the lower side of the side, but this configuration is not limited to this. There may be no side opening 22, or three or more openings may be formed in the storage section 2. In addition, the position where the side openings 22 are formed is not limited to the lower side of the side of the storage section 2, but may be near the upper side or center (center of height in the Z-axis direction) of the side, or may be on the front or back of the storage section 2. However, in terms of the above-mentioned effect, it is desirable that the side openings 22 are arranged on the lower side of the side of the storage section 2.

[0041] In this embodiment, the waist bag 1 is provided with a base member 11 having a trapezoidal planar shape, but the present invention is not limited to this configuration. The planar shape of the base member 11 may be, for example, a rectangle or a polygon, or may be a T-shape or an H-shape. Furthermore, the surface S1 of the base member 11 is not limited to a flat surface, and the surface S1 may be a curved surface, or the base member 11 may be configured to be bent.

[0042] In addition, in this embodiment, the waist bag 1 is provided with a cover member 12 having a substantially T-shaped planar shape, but the present invention is not limited to this configuration. The planar shape of the cover member 12 may be, for example, a rectangle, a polygon, a Y-shape, an H-shape, or the like. The shape and position of the side opening 22 vary depending on the planar shape of the cover member 12. In addition, in this embodiment, the cover member 12 is formed into a substantially T-shape by cutting out the outer edge of a rectangle, but the cover member 12 may be provided with a through hole (an opening that does not contact the outer edge).

[0043] In addition, in this embodiment, the storage section 2 having the base member 11, the cover member 12, the partition members 13 and 14, etc., is exemplified, but the present invention is not limited to this configuration. The storage section may be composed of only the base member 11 and the cover member 12. The storage section 2 may be bag-shaped or box-shaped, and may be, for example, a bag-shaped member made by folding only one member (base member), or a bag-shaped member made by assembling three or more members. Furthermore, the storage section 2 may be, for example, a base member bent into a cylindrical shape to which another member is attached as a bottom plate.

[0044] In the present embodiment, the waist bag 1 is exemplified in which the opening 21 formed on the upper side of the storage section 2 is open, but the opening 21 may be on the lower side. Also, the opening 21 may be covered with a lid or cover. Also, in the present embodiment, an example is shown in which the belt attachment member 3 is connected to the upper side of the outer surface of the storage section 2 (the back surface S2 of the base member 11) by riveting, but this configuration is not limited to this. The belt attachment member 3 may be connected to the inner surface of the storage section 2 (the front surface S1 of the base member 11). Also, the belt attachment member 3 may be connected by sewing, or may be integrated with the storage section 2.

[0045] In this embodiment, an example is shown in which the first magnetic body G1 is a round magnet and the second magnetic body G2 is a rectangular iron plate, but this is not limited to this configuration. Either the first magnetic body G1 or the second magnetic body G2 may be a magnet, or both may be magnets. In addition, the shapes of the first magnetic body G1 and the second magnetic body G2 can be changed as appropriate, but from the viewpoint of attachment and detachment, it is preferable that the surface is flat (with few irregularities, etc.) and the thickness (height in the Z-axis direction) is thin. The planar shape of the first magnetic body G1 and the second magnetic body G2 may be, for example, a circle or a rectangle, as well as a polygon, an ellipse, an L-shape, a T-shape, a crank shape, etc. In addition, in this embodiment, an example is shown in which the waist bag 1 includes one first magnetic body G1 and one second magnetic body G2, but this is not limited to this configuration. The number of the first magnetic body G1 and the second magnetic body G2 may be one or more. Furthermore, in the present embodiment, the waist bag 1 is illustrated in which the first magnetic body G1 and the second magnetic body G2 are partly opposed to each other (the first magnetic body G1 and the second magnetic body G2 are partly overlapped when viewed from the Y-axis direction) when the belt attachment member 3 is fixed to the storage section 2, but the present invention is not limited to this configuration. When the belt attachment member 3 is fixed to the storage section 2, the first magnetic body G1 may be entirely overlapped with the second magnetic body G2, or vice versa. The degree of overlap between the first magnetic body G1 and the second magnetic body G2 may be determined in consideration of the fixing force required for the belt attachment member 3 and the storage section 2 (magnetic force, type, shape, area, arrangement, etc. of the magnetic body).

[0046] Second Embodiment In the second embodiment, an example of a waist bag having a belt attachment member with a different shape is shown.

[0047] FIG. 13(A) is a rear view of the waist bag 1A, and FIG. 13(B) is a rear view of the waist bag 1A with the belt attachment member 3A opened 180 degrees.

[0048] The waist bag 1A differs from the waist bag 1 according to the first embodiment in that it includes a belt attachment member 3A, two first magnetic bodies G1A, and two second magnetic bodies G2A. The rest of the configuration is the same as that of the waist bag 1.

[0049] The belt attachment member 3A has a rectangular belt insertion portion 31A. The two first magnetic bodies G1A are magnets with a round planar shape attached to the lower outer surface of the storage section 2, and are arranged in the X-axis direction. The two second magnetic bodies G2A are round magnets with approximately the same shape and size as the first magnetic body G1A. The two second magnetic bodies G2A are arranged at positions corresponding to the first magnetic body G1A when the belt attachment member 3A is fixed to the storage section 2. As shown in FIG. 13(A), the first magnetic body G1A and the second magnetic body G2A are approximately overlapped when viewed from the Y-axis direction.

[0050] Third embodiment In the third embodiment, an example of a waist bag having a belt attachment member with a different shape is shown.

[0051] FIG. 14(A) is a rear view of the waist bag 1B, and FIG. 14(B) is a rear view of the waist bag 1B with the belt attachment member 3B opened 180 degrees.

[0052] The waist bag 1B differs from the waist bag 1 according to the first embodiment in that it includes a belt attachment member 3B, two first magnetic bodies G1B, and two second magnetic bodies G2B. Other than that, the configuration is the same as that of the waist bag 1.

[0053] The belt attachment member 3B has a tapered (sword-shaped) belt insertion portion 31B. The two first magnetic bodies G1B are magnets with a round planar shape attached to the lower outer surface of the storage section 2, and are arranged in the Z-axis direction. The two second magnetic bodies G2B are round magnets with approximately the same shape and size as the first magnetic body G1B. The two second magnetic bodies G2B are arranged at positions corresponding to the first magnetic body G1B when the belt attachment member 3B is fixed to the storage section 2. As shown in FIG. 14(A), the first magnetic body G1B and the second magnetic body G2B are approximately overlapped when viewed from the Y-axis direction.

[0054] Other Embodiments In the above embodiment, the material of the storage section 2 and the belt attachment members 3, 3A, 3B is 4 mm thick tannin-tanned cowhide, but the material is not limited to this. The material and thickness can be changed as appropriate as long as the storage section 2 and the belt attachment members 3, 3A, 3B have the required rigidity and plasticity. The material of the storage section 2 and the belt attachment members 3, 3A, 3B may be, for example, leather of other animals, chrome-tanned leather, canvas, iron plate, thermoplastic resin, etc. Furthermore, the entirety of the waist bag does not need to be made of the same material, and different materials may be combined for each part.

[0055] In the above embodiment, the waist bag has one belt attachment member, but there may be multiple belt attachment members. However, if there are multiple belt attachment members, it may be difficult to attach and remove the waist bag. Therefore, from the viewpoint of ease of attaching and removing the waist bag, it is preferable that there is only one belt attachment member.

[0056] The waist bag of the present invention is not limited to being attached only to the waist belt 50, and may be, for example, hooked and clamped on a thin fabric (pocket, trousers, bag, etc.) and secured with the first and second magnetic bodies. A magnetic body such as an iron plate may be embedded in the fabric, the belt attachment member may be hooked on, and secured with a magnet (the first and second magnetic bodies). When not in use, the belt attachment member may be hooked on a magnetic body such as an iron plate and secured with a magnet (the first or second magnetic body).

[0057] Finally, the above-described embodiment is illustrative in all respects and is not restrictive. Modifications and changes are possible for those skilled in the art. The scope of the present invention is indicated by the claims, not the above-described embodiment. Furthermore, the scope of the present invention includes modifications from the embodiments within the scope of the claims and the equivalent scope. [Explanation of symbols]
