Description

[Technical Field]

[0001] The present invention relates to a site inspection bag used when inspecting a construction site or the like. [Background technology]

[0002] Tool cases, measuring instruments, tools, machines, etc. that can be attached to waist belts and used as waist tools have been developed for workers such as craftsmen at construction sites. For example, a system that combines a bracket and holder called SEF (registered trademark) offers a variety of waist tool cases and measuring instruments with integrated brackets. By attaching the holder to a work belt or waist belt, the worker can select the tool case or measuring instrument needed for the job and attach it to the belt holder.

[0003] On the other hand, not only construction site workers but also managers such as company presidents and site supervisors may use a variety of measuring instruments, tools, machines, etc. to carry out surveys and work at construction sites. However, managers often do not stay at the site for long periods of time because they have a lot of work to do off-site, such as meetings and business negotiations, and they often wear business attire at the site. As a result, managers often carry the measuring instruments, tools, machines, etc. used for site surveys in a regular business bag rather than attaching them to a belt. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-89185 Summary of the Invention [Problem to be solved by the invention]

[0005] Here, for measuring instruments and tools used by managers and others in on-site investigations, it is preferable to use bracket-equipped types that are easy for craftsmen and other workers to use as waist tools, from the perspective of reducing individual variations between products, unifying handling methods, and standardizing spare parts.

[0006] However, when managers and others carry measuring instruments and tools used in on-site surveys in a regular business bag, the advantages of measuring instruments with brackets that are easy to attach to a waist belt and are convenient to use as waist tools are not utilized, and in fact they have disadvantages such as being bulky compared to measuring instruments without brackets.

[0007] The present invention has been made in view of the above circumstances, and relates to a site inspection bag that can be suitably used by managers and the like when inspecting construction sites. [Means for solving the problem]

[0008] The site investigation bag according to the present invention comprises a bag first surface; The second side of the bag and a storage section formed between the bag first surface and the bag second surface, through which items can be put in and taken out via an opening and closing section; a belt extending in a horizontal direction is attached to the first bag surface with a horizontal slack of 2 to 25% relative to the opposing first bag surface; the belts are fixed to the bag first surface at 2 to 12 fixed positions each extending along a vertical direction perpendicular to the horizontal direction and spaced apart from one another in the horizontal direction; Between at least one pair of adjacent fixing positions among the 2 to 12 fixing positions, the horizontal spacing between the fixing positions is 30 to 100 mm, and a waist tool holder insertion portion is formed that passes vertically through the gap between the first surface of the bag and the belt.

[0009] In this type of site investigation bag, a waist tool holder that is attached to a waist belt or the like can be suitably attached to the waist tool holder hole formed on the first surface of the bag. That is, in this site investigation bag, a holder for attaching a bracket-equipped measuring instrument or the like can be fixed to the belt attached to the first surface of the bag, just like a waist belt for attaching waist tools. In particular, because the belt fixed to the first surface of the bag is fixed with a moderate amount of appropriate slack and at appropriate intervals along the horizontal direction by fixing positions extending vertically, holders for attaching bracket-equipped measuring instruments or the like can be reliably fixed in a state suitable for use.

[0010] Furthermore, this type of site investigation bag allows measuring instruments and tools with brackets to be detachably attached to a holder fixed to a belt and carried around, making the measuring instruments and tools easier to use and contributing to the efficiency of site investigations. Also, by standardizing the tools and measuring instruments used by craftsmen and other workers as waist tools and the tools and measuring instruments used by managers and others for site investigations, it is possible to streamline the management of tools and measuring instruments and training on their use. Furthermore, by fixing measuring instruments and tools with brackets to a belt, it is possible to avoid placing measuring instruments and documents in the storage compartment together, which effectively prevents problems such as documents getting wrinkled.

[0011] The width of the belt in the vertical direction may be 25 to 60 mm, and the thickness of the belt in the direction away from the first surface of the bag may be 0.5 to 5 mm.

[0012] By setting the vertical width and thickness of the belt fixed to the first surface of the bag within a specified range close to the width of currently used work belts and waist belts, a bracket mounting holder for waist tools, which is intended to be attached to a waist belt, etc., can be properly fixed without any processing.

[0013] Also, for example, the belt may be a fabric belt. The belt may be sewn and fixed to the first surface of the bag at the fixed position.

[0014] There are no particular restrictions on the material of the belt fixed to the first surface of the bag, but a cloth belt is preferable because the fixed position by sewing is highly durable, and it is lightweight and inexpensive.

[0015] Further, for example, the belt may be fixed to the first surface of the bag at four or more of the fixing positions, and a plurality of waist tool holder threading portions may be formed, The plurality of waist tool compatible holder passing portions may include first passing portions in which the horizontal spacing between the fixing positions is 30 to 50 mm, and second passing portions in which the horizontal spacing between the fixing positions is 60 to 80 mm.

[0016] By forming the first through-portion and the second through-portion, two types of holders with different standards can be securely fixed in place in an easy-to-use state.

[0017] Furthermore, for example, the plurality of waist tool compatible holder passing portions may include a plurality of the first passing portions and a plurality of the second passing portions, and the first passing portions and the second passing portions may be arranged alternately along the horizontal direction.

[0018] By arranging the first and second threading parts alternately, when fixing holders of the same standard to multiple belts, the fixing intervals of the holders can be appropriately ensured, and all can be reliably fixed in a state that is easy to use.

[0019] The belt may be provided in a lower half region of the first surface of the bag.

[0020] When a measuring instrument with a bracket is attached to a holder fixed to the belt, the measuring instrument itself protrudes away from the first surface of the bag. However, by providing the belt in a lower area, the attached measuring instrument can be prevented from interfering with other structures of the bag, such as pockets. Furthermore, with this type of site investigation bag, it is easy to attach long tools or measuring instruments to the holder fixed to the belt. Another advantage is that the site investigation bag 10 can easily stand on its own with a measuring instrument with a bracket attached.

[0021] Also, for example, a clip for clamping and fixing paper may be provided on the second surface of the bag, The second bag surface may include a support board having a substantially rectangular flat plate shape that supports the second bag surface so that the surface is substantially flat.

[0022] The second side of such a site survey bag can be used as a binder for viewing and writing on paper drawings during a site survey.

[0023] Further, for example, the work bag according to the present invention may include a pair of handles provided so as to protrude upward from the first surface and the second surface of the bag; It may further include a shoulder belt having a width of 30 to 50 mm.

[0024] This type of on-site investigation bag with a handle and shoulder strap allows for easy attachment and detachment of bracket-equipped measuring instruments to and from the holders attached to the belt, contributing to the efficiency of on-site investigations. It is also possible to attach different types of holders to the shoulder strap. Furthermore, on-site investigation measuring instruments and tools can be easily carried regardless of the type of clothing worn.

[0025] Furthermore, for example, the bag bottom, which is the bottom of the storage section, may be provided with a length-adjustable bottom fixing belt that can fasten and hold a long object to the bag bottom.

[0026] This type of field survey bag is convenient for field surveys because it allows long objects such as tripods to be secured to the bottom of the bag.

[0027] In addition, in the field investigation bag according to the present invention, a holder to which a bracket-equipped waist tool can be detachably attached may be fixed to at least one of the waist tool holder insertion portions.

[0028] The holder to be fixed to the waist tool holder hole may be selected and attached by the user of the field investigation bag, or a holder corresponding to a specific bracket may be fixed in advance. [Brief explanation of the drawings]

[Figure 5] FIG. 5 is an external view of the field investigation bag shown in FIG. 1, observed from the second surface side of the bag. DETAILED DESCRIPTION OF THE INVENTION

[0030] 1 is an external view showing a site investigation bag 10 according to one embodiment of the present invention. The site investigation bag 10 has a bag body 12 that is generally rectangular in front view and has a rectangular parallelepiped shape with a predetermined thickness, but the shape of the site investigation bag 10 is not limited to the shape shown in FIG.

[0031] Fig. 1 is an external view of the site investigation bag 10 as seen from the bag first surface 20 side, and Fig. 4 is an external view of the site investigation bag 10 as seen from the bag second surface 40 side. As shown in Figs. 1 and 4, the site investigation bag 10 has the bag first surface 20 which is the surface on the front side, the bag second surface 40 which is the surface on the back side, and a storage section 50 which is formed between the bag first surface and the bag second surface and through which items can be put in and taken out via an opening and closing section (not shown in Figs. 1 and 5) which is provided with a zipper or the like.

[0032] The size of the field investigation bag 10 is not particularly limited, but for example, each side of the bag first surface 20 and bag second surface 40 can be approximately 30 to 40 cm, but it is preferable that the storage section 50 be able to store A4-sized (A3 folded in half) documents and drawings.

[0033] 1, the bag first surface 20 is provided with multiple outer pockets 31 and a belt 22. The outer pockets 31 are provided above the belt 22 on the bag first surface 20 and can store writing implements, small items, communication devices, etc. The belt 40 is provided below the outer pockets 31 in the lower half of the bag first surface 20.

[0034] 1, the belt 22 extends in the horizontal direction D1 on the bag first surface 20. The belt 22 is attached to the bag first surface 20 with a slight slack in the horizontal direction D1 of 2 to 25% relative to the bag first surface 20 that the belt 22 faces. The horizontal direction D1 refers to the direction that is horizontal to the ground when the field investigation bag 10 is carried by the handle 72 or shoulder belt 74.

[0035] The belt 22 is fixed to the bag first surface 20 at two to twelve fixing positions 24 spaced apart from one another in the horizontal direction D1. The belt 22 shown in FIG. 1 is fixed to the bag first surface 20 at eight fixing positions 24, including a first fixing position 24a, a second fixing position 24b, a third fixing position 24c, a fourth fixing position 24d, a fifth fixing position 24e, a sixth fixing position 24f, a seventh fixing position 24g, and an eighth fixing position 24h. Each fixing position 24 extends along a vertical direction D2 that is perpendicular to the horizontal direction D1. In particular, each fixing position 24 preferably extends over substantially the entire vertical direction D2 of the belt 22, and the belt 22 is fixed to the bag first surface 20 continuously from the upper end to the lower end of the width direction of the belt 22 at each of the fixing positions 24a to 24h.

[0036] The width of the belt 22 in the vertical direction D2 is not particularly limited, but is preferably about 25 to 60 mm. The thickness of the belt 22 in the direction away from the bag first surface 20 is not particularly limited, but is preferably about 0.5 to 5 mm. By setting the width and thickness of the belt in the vertical direction D2 within a predetermined range, the holder 94 described below can be properly supported. Furthermore, by setting the width and thickness of the belt 22 in the vertical direction D2 to values ​​similar to those of currently used waist belts, etc., a bracket mounting holder (such as the holder 94) intended for attachment to a waist belt can be properly fixed without any processing. The vertical direction D1 refers to the direction perpendicular to the ground when the site investigation bag 10 is carried by the handle 72 or shoulder belt 74.

[0037] Furthermore, among the two to twelve fixing positions 24a-24g for fixing the belt 22, at least one pair (seven pairs in the example shown in FIG. 1) of adjacent fixing positions 24a-24g has a waist tool holder passing-through portion 26 formed between them. The horizontal intervals L1, L2, L3 between the adjacent fixing positions 24a-24g that form the waist tool holder passing-through portion 26 are 30 to 100 mm, and the waist tool holder passing-through portion 26 has a gap that penetrates between the bag first surface 20 and the belt 22 in the vertical direction D2.

[0038] The belt 22 may be fixed to the bag first surface 20 at three fixing positions, but as shown in Fig. 1, it is preferable that the belt 22 is fixed to the bag first surface 20 at four or more fixing positions 24a to 24g, and the site investigation bag 10 is formed with multiple (more preferably three or more) waist tool holder insertion portions 26. This allows a variety of tools, measuring instruments, etc. to be attached to the bag first surface 20 using holders 94 (see Fig. 2).

[0039] 1, the plurality of waist tool holder threading sections 26 formed by the belt 22 and the bag first surface 20 include first threading sections 26a, 26b, and 26c, each having a horizontal distance D1 of 30 to 50 mm between adjacent fastening positions 24a to 24h, and second threading sections 26d and 26e, each having a horizontal distance D1 of 60 to 80 mm between the fastening positions 24a to 24h. That is, as shown in FIG. 1, first threading section 26a is formed between the second fastening position 24b and the third fastening position 24c, first threading section 26b is formed between the fourth fastening position 24d and the fifth fastening position 24e, and first threading section 26c is formed between the sixth fastening position 24f and the seventh fastening position 24g.

[0040] Second through-hole 26d is formed between third fixing position 24c and fourth fixing position 24d, and second through-hole 26e is formed between fifth fixing position 24e and sixth fixing position 24f. First fixing position 24a is located at one end of belt 22 in horizontal direction D1, and eighth fixing position 24h is located at the other end of belt 22 in horizontal direction D1, with second to seventh fixing positions 24b to 24g being located in order between first fixing position 24a and eighth fixing position 24h.

[0041] As shown in FIG. 1, the multiple waist tool holder threading portions 26 formed by the belt 22 and the bag first surface 20 include multiple (three in the embodiment) first threading portions 26a, 26b, 26c and multiple (two in the embodiment) second threading portions 26d, 26e, and the first threading portions 26a, 26b, 26c and the second threading portions 26d, 26e are arranged alternately along the horizontal direction D1.

[0042] Furthermore, the multiple waist tool holder threading portions 26 formed by the belt 22 and the bag first surface 20 include third threading portions 26f and 26g in addition to first threading portions 26a, 26b, and 26c and second threading portions 26d and 26e. The third threading portion 26f is formed between the first fixing position 24a and the second fixing position 24b, and the third threading portion 26g is formed between the seventh fixing position 24g and the eighth fixing position 24h. The third threading portions 26f and 26g are located at both ends of the belt 22 in the horizontal direction D1, and the first threading portions 26a, 26b, and 26c and the second threading portions 26d and 26e are located between the two third threading portions 26f and 26g.

[0043] The material of the belt 22 arranged on the bag first surface 20 is not particularly limited, but from the viewpoint of durability, for example, it is preferable that the belt 22 be a cloth belt. The belt 22 is fixed by sewing to the bag first surface 20 at fixing positions 24a to 24h. However, the belt 22 may also be a belt made of leather, synthetic leather, resin, or the like, and the method of fixing the belt 22 to the bag first surface 20 is not limited to sewing, but may be a method other than sewing, such as gluing or riveting.

[0044] FIG. 2 is an external view showing an example of a state in which a holder 94 (a Sef (registered trademark) system holder) designed for attaching tools and measuring instruments with brackets compatible with waist tools is fixed to the site investigation bag 10 shown in FIG. 1. In the example shown in FIG. 2, the holder 94 is fixed to each of the three first threading portions 26a, 26b, and 26c of the multiple waist tool compatible holder threading portions 26 shown in FIG. 1. By fixing the holder 94 as shown in FIG. 2 before using the site investigation bag 10, any type of tool or measuring instrument equipped with a bracket compatible with the holder 94 can be fixed to the bag first surface 20 as shown in FIG. 3.

[0045] The holder 94 shown in FIG. 2 is a mountable type holder 94 that can be attached to a waist belt (without passing the end of the belt through) to which tools and measuring instruments used as waist tools are attached.

[0046] In the example shown in FIG. 2, the holders 94 are secured to the three first threading portions 26a, 26b, and 26c. However, the attachment positions of the holders 94 on the field investigation bag 10 are not limited to the example shown in FIG. 2. For example, holders for attaching bracket-equipped tools and measuring instruments for waist tools may be secured to the two second threading portions 26d and 26e, or holders may be secured to the third threading portions 26f and 26g at both ends of the belt 22. However, as shown in FIG. 2, by arranging the holders 94 at the first threading portions 26a, 26b, and 26c spaced apart by one, large measuring instruments and tools in the horizontal direction D1 can be attached without interference. Furthermore, by arranging the holders so as to avoid the third threading portions 26f and 26g at both ends, the attached measuring instruments and tools can be prevented from protruding from both sides of the bag's first surface 20.

[0047] 3 is an external view showing a state in which tools and measuring instruments with brackets that can also be used as waist tools, such as convex tools 95, laser rangefinders 96, and carabiners 97, are attached to each holder 94 fixed to first through portions 26a, 26b, and 26c in FIG. 2. Tools and measuring instruments, such as convex tools 95, laser rangefinders 96, and carabiners 97, have brackets that correspond to holders 94 and can be attached and detached with a single touch to each holder 94. Note that tools and measuring instruments that have brackets that correspond to holders 94 and can be used as waist tools include various measuring instruments, tools, and tool boxes that are attached to work belts or waist belts, and examples of these include LED lights, waist bags, tool holders, and levels in addition to those shown in FIG. 3.

[0048] As shown in FIG. 2, the site inspection bag 10 includes a holder 94 that can be attached to the waist tool holder slot 26 in advance. This allows the user to select and carry tools and measuring instruments needed for the site inspection from a stock of tools and measuring instruments with brackets that can also be used as waist tools, as shown in FIG. 3. As shown in FIG. 3, by attaching tools and measuring instruments compatible with waist tools, such as a convex 95, a laser rangefinder 96, and a carabiner 97, to the first surface 20 of the bag, construction site managers and others using the site inspection bag 10 can use and store these measuring instruments without opening the bag's storage compartment 50, thereby enabling efficient inspections and work. Furthermore, as shown in FIG. 3, the ability to attach bracket-equipped measuring instruments and tools to the belt 22 avoids placing measuring instruments and other items in the storage compartment 50 together with documents and drawings, thereby effectively preventing the documents and drawings stored in the storage compartment 50 from becoming wrinkled.

[0049] The site inspection bag 10 can be fitted with a holder 94 fixed to the first surface 20 of the bag, which is the same holder that is attached to a waist belt or the like by workers such as craftsmen at construction sites to attach waist tools. This allows the tools and measuring instruments that workers and others use as waist tools when working on site to be standardized with the tools and measuring instruments that managers and others use for site inspections, thereby streamlining the management of tools and measuring instruments and training on their use.

[0050] As shown in FIG. 3, waist-mounted tools and measuring instruments, such as a convex 95, a laser rangefinder 96, and a carabiner 97, secured to the site investigation bag 10 via a holder 94, are preferably secured firmly to the belt 22 without excessive slack. In the site investigation bag 10, the slack in the horizontal direction D1 of the belt 22 is set to 2 to 25% (the belt 22 connecting adjacent fixed positions is 2 to 25% longer than the distance between adjacent fixed positions), allowing the holders and measuring instruments to be secured to the site investigation bag 10 in an appropriate state. Furthermore, by allowing the belt 22 to have some slack, excessive force can be avoided from being applied to the fixed positions 24 when securing the holder 94 to the belt 22.

[0051] Furthermore, the site investigation bag 10 has a belt 22 provided in the lower half of the bag's first surface 20, which prevents waist tools such as measuring instruments attached via holders 94 shown in FIG. 2 from interfering with other structures of the bag, such as the outer pocket 31. Furthermore, the belt 22 provided in the lower half of the bag's first surface 20 makes it easier for the site investigation bag 10 to stand on its own when the convex 95, laser rangefinder 96, carabiner 97, etc. are attached to the bag's first surface 20 via the belt 22. In other words, the site investigation bag 10 has the advantage of being less likely to tip over due to the weight of measuring instruments, etc., when the site investigation bag 10 is installed with the bag's first surface 20 perpendicular to the installation surface.

[0052] As shown in Figures 1 to 3 and 5, the site investigation bag 10 may have a pair of handles 72 that protrude upward from the first bag surface 20 and the second bag surface 40, and a shoulder belt 74 that is 30 to 50 mm wide. By having the handles 72, it is possible to hold the site investigation bag 10 with one hand by grasping the handles 72, and easily attach and detach waist-mounted measuring instruments and the like that are fixed to the site investigation bag 10 with the other hand. Also, as shown in Figures 2 and 3, a vertical belt holder 94a can be attached to the shoulder belt 74, allowing other tools and measuring instruments to be attached to the shoulder belt 74.

[0053] As shown in Fig. 4, the direction in which the shoulder belt 74 to which the vertical belt holder 94a is fixed extends and the direction D3 in which the bracket is inserted into the vertical belt holder 94a are parallel. On the other hand, in the holder 94 shown in Fig. 2, the direction in which the bracket is inserted into the holder 94 is perpendicular to the horizontal direction D1, which is the direction in which the belt 22 to which the holder 94 is fixed extends.

[0054] Figure 5 is an external view of the field investigation bag 10 viewed from the side of the bag's second surface 40. As shown in Figure 5, the bag's second surface 40 is provided with clips 42 for clamping and securing paper. The bag's second surface 40 also has a support board 44 in the shape of a substantially rectangular plate that supports the surface of the bag's second surface 40 so that it is substantially flat. The support board 44 may be built into the inside of the bag's second surface 40 as shown in Figure 5, or may be exposed on the outer surface of the bag's second surface 40.

[0055] The support board 44 is preferably made of, for example, a resin plate, and preferably occupies 80 to 100% of the area of ​​the bag's second surface 40. In such a site investigation bag 10, the bag's second surface 40 can be used as a binder for viewing and writing on paper drawings during a site investigation. The support board 44 on the bag's second surface 40 also serves to maintain the roughly rectangular shape of the site investigation bag 10. Therefore, a site investigation bag 10 with a support board 44 can prevent the problem of the site investigation bag 10 losing its shape and becoming difficult to use, even when heavy measuring instruments or tools are attached to the bag's first surface 20.

[0056] 1 to 3 and 5, the bag bottom 60, which is the bottom of the storage section 50 of the field investigation bag 10, is provided with length-adjustable bottom fixing belts 62 that can fasten and hold a long object 92 to the bag bottom 60. The bottom fixing belts 62 are provided at three locations on the bag bottom 60: both ends in the horizontal direction D1 and the center. Examples of long objects 92 that can be fixed to the bag bottom 60 by the bottom fixing belts 62 include measuring instruments and camera tripods.

[0057] The bottom fixing belt 62 has a hook-and-loop fastener, and the length can be adjusted by changing the connection position of the hook-and-loop fastener. However, the method for adjusting the length of the bottom fixing belt 62 is not limited to using the hook-and-loop fastener, and the bottom fixing belt 62 may also be length adjustable using length adjustment metal fittings, etc.

[0058] While the site investigation bag 10 according to the present invention has been described above using the above-described embodiments, it goes without saying that many other embodiments and examples are within the technical scope of the present invention. For example, while the belt 22 forming the waist tool holder slot 26 is provided in one location on the first surface 20 of the site investigation bag 10, the waist tool holder slot 26 may be formed by other belts in multiple locations on the first surface 20 or on the second surface 40. Furthermore, the holder 94 secured to the waist tool holder slot 26 and the corresponding bracket-equipped measuring instrument or tool are not limited to those from a specific manufacturer, as long as they are detachable from each other.
