Description

Technical Field

[0001] The utility model relates to a measuring instrument backpack used for carrying a laser measuring instrument. Background Art

[0002] Traditionally, hard cases made from resin molding have been used as carrying cases for laser measuring instruments. This is because laser measuring instruments are precision equipment that must accurately irradiate distant objects with laser light. This poses a risk of slight deformation of the housing, which could damage the glass window that emits the laser light, or the prism that receives the laser light.

[0003] In this respect, the hard case containing the laser measuring instrument is heavy and requires a lot of strength to carry. Therefore, the hard case is provided with a pair of shoulder straps in a detachable manner so that the hard case can be carried on the back (see, for example, Patent Document 1).

[0007] Problems to be solved by utility models

[0008] However, regarding the type of product of Patent Document 1 that requires carrying a hard case, no matter how it is carried, the case itself is heavy or hard, and furthermore, the shoulder strap must be attached and detached, making it difficult to carry.

[0009] Therefore, the inventors considered storing the laser measuring instrument in a lightweight fabric backpack rather than a hard case, and placing a cushion close to the perimeter of the laser measuring instrument for protection. Furthermore, since components such as the prism could be damaged when placed in and out of the measuring instrument, the inventors considered providing a space in the top cover to accommodate these components.

[0010] Furthermore, such a backpack cannot have its lid opened widely like a hard case, and it is difficult to take out the measuring machine while the mat is still in close contact with it, making it difficult to put in and take out the heavy measuring machine.

[0011] Furthermore, if the cover accommodates a prism or other components, when the main body of the measuring instrument is taken out of the backpack and the cover is removed, the prism or other components may be damaged due to the shaking.

[0012] The present invention is made to solve the above-mentioned problems, and its purpose is to provide a surveying instrument backpack that can be easily carried while protecting a laser surveying instrument, can easily put in and take out the laser surveying instrument, and effectively prevents damage to surveying instrument components.

[0013] Means used to solve problems

[0014] The above-mentioned problem is solved by a surveying instrument backpack, which comprises: a bag main body having a storage space for accommodating a laser measuring instrument on its inner side, a cushion for protecting the laser measuring instrument, a cover covering the storage space, and a pair of shoulder straps on the back side; the bag main body has an opening portion, the opening portion including a top opening portion and a front opening portion, the top opening portion being used for placing the laser measuring instrument into or taking it out of the storage space at the top side, the front opening portion being formed continuously with the top opening portion, and a part of the front side being open, the cover being attached to the peripheral edge portion of the opening portion in an openable and closable manner so that the cover can be flipped open with the lower peripheral edge portion of the front opening serving as a fulcrum, a storage box for accommodating parts and / or accessories of the laser measuring instrument being connected to the area of the cover covering the top opening, and a cushioning material is provided on the outer wall of the storage box in an area where the bag main body is placed and the cover is flipped open and touches the ground.

[0015] The surveying instrument backpack, according to the above structure, includes a flexible bag body with a storage space inside for accommodating a laser surveying instrument; a cushion for protecting the laser surveying instrument; and a pair of shoulder straps on the back. Thus, the flexible bag body can be adjusted to the body's shape while being carried, making it easy to carry the laser surveying instrument. Furthermore, the cushion protects the laser surveying instrument.

[0016] The bag body also features a top opening and a front opening. The top opening serves as the entrance and exit for the laser measuring instrument. The front opening is continuous with the top opening and partially opens onto the front. Therefore, when the cover covering the opening is opened, a large opening stretches from the top opening to the front opening, making it easy to insert and remove the measuring instrument.

[0017] The cover is attached to the peripheral edge of the opening in an openable and closable manner so that the cover can be flipped open with the lower peripheral edge of the front opening as a fulcrum. Therefore, as long as the cover can be opened and flipped open, the measuring instrument can be taken in and out of the large opening.

[0018] Because the fulcrum is located at the lower edge of the front opening, opening the cover could cause it to collide with a concrete floor or ground, potentially damaging components such as the prism inside the storage box connected to the cover. However, cushioning material is provided on the outer wall of the storage box in the area where the bag body lands when the cover is opened. This cushioning reduces the impact of impact with the ground, effectively preventing damage to components.

[0019] In addition, preferably, it is characterized in that the pad has a first pad that contacts the peripheral side of the laser measuring instrument and a second pad that presses the head of the laser measuring instrument from above, the first pad is configured so that the upper surface of at least the front side is equal to or lower than the fulcrum, and the second pad is connected to the lower surface of the cover.

[0020] Therefore, when the cover is opened, the first mat does not block the front opening of the bag body, allowing the laser meter to be easily inserted and removed through the wide opening. Furthermore, the first mat has no height and does not come into contact with the entire side surface of the laser meter, thus preventing the mat from clinging too tightly to the bag, making it difficult to remove the laser meter.

[0021] In this regard, if the first pad is not raised above the fulcrum, the pad will not cover the circumference of the laser measuring instrument. However, the second pad located on the lower surface of the cover can press the head of the laser measuring instrument from above and securely secure it. Moreover, since the second pad is connected to the cover, it moves with it when the cover is opened, making it easy to insert and remove the laser measuring instrument.

[0022] Furthermore, when the cover is inverted and flipped open, the second cushion attached to the cover's lower surface is positioned on the front side of the storage box, thereby also serving as a cushion to protect the front of the storage box. Furthermore, in this configuration where the second cushion is attached to the cover's lower surface, the left and right sides of the storage box are preferably colored more prominently than the surrounding left and right sides. In this way, when the cover is flipped open, the front side of the storage box is protected by the second cushion, the back side by the first cushion, and the bottom side by the cushioning material 50. Furthermore, the prominent colors of the left and right sides attract the user's attention and prevent the user from being kicked.

[0023] Furthermore, the first mat is preferably interchangeable to accommodate a variety of laser measuring instruments and is shaped so that the battery of the laser measuring instrument contained therein is positioned on the back side. Therefore, the first mat can be appropriately interchanged to create a backpack for various laser measuring instruments. Furthermore, when worn, the heavy battery can be naturally positioned near the back, making it easier to carry.

[0024] In addition, preferably, it is characterized in that the storage box is arranged on the upper surface of the cover,

[0025] The top surface of the storage box slopes downward as it approaches the front side when the cover covers the storage space. This allows rain that strikes the top surface of the storage box to flow directly toward the front side, preventing the components inside from getting wet. Furthermore, even if small stones or the like strike the sloped surface, the impact is mitigated, effectively protecting the components inside.

[0026] Furthermore, the bag body preferably includes a side surface of a cloth longer than the front-to-back length of the side surface of the bag body, and a pressing unit that freely presses the side surface of the bag body when the cloth is folded. This allows a large cloth to be folded and held against the side surface. Furthermore, by releasing the pressing unit and unfolding the folded cloth, a long object, such as a measuring rod, can be inserted into the cloth. The long object can then be held in the bag by pressing the cloth again with the pressing unit.

[0027] Utility model effect

[0028] As described above, according to the present invention, a surveying instrument backpack can be provided that can be easily carried while protecting a laser surveying instrument, can be easily inserted and removed, and can effectively prevent damage to surveying instrument components.

[0039] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0040] In addition, the embodiments described below are preferred specific examples of the present invention, and therefore various preferred limitations are added technically. As long as there is no special description of the subject matter of the present invention in the following description, the scope of the present invention is not limited to these embodiments. In addition, in each of the drawings, the same reference numerals are given to the same structural elements, and their detailed descriptions are appropriately omitted.

[0041] In addition, the "front side" below refers to the side opposite to the shoulder straps for the user to wear on the back, and each side is shown with reference to the front side.

[0042] (Overall structure of a measuring instrument backpack)

[0043] Figures 1 to 4B It is a backpack called a knapsack, a rucksack, etc., and is particularly suitable for carrying a laser measuring instrument (hereinafter referred to as a "measurement instrument") TD. In addition, Figures 1 to 3 A portion of the shoulder strap 8 is omitted.

[0044] The backpack 1 shown in these figures is generally shaped like a square prism with a bottom and a hollow interior. The base is made of a woven or non-woven synthetic fiber fabric, and is flexible enough to adapt to the user's body shape when worn. Furthermore, despite the base's flexibility, the backpack 1 is able to stand independently thanks to various cushions described below.

[0045] The backpack 1 includes a "bag body 2," a "cushion 4," a "cover 5," and "shoulder straps 8." These components will be briefly described below.

[0046] First, the overall structure of the bag main body 2 will be described.

[0047] The bag body 2 includes a storage space S for storing the measuring instrument TD in a standing state inside. In addition, a means for fixing components that are not prone to damage even if slightly damaged may be provided in the storage space S.

[0048] At least the surface of the lower portion 2A including the bottom of the bag body 2 is made of rubber cloth, which exhibits waterproof and stain-resistant properties to prevent the measuring instrument TD from getting wet or dirty when placed on the ground.

[0049] A front bag 16 having a small thickness and serving as a bag is provided on the front of the bag body 2. Figure 1 as well as Figure 3 As shown, the front pocket 16 can be opened and closed by a zipper 17 provided along the side in a vertical direction. The zipper 17 is composed of zipper teeth and a slider that engages with the zipper teeth. The slider is provided with a rubber handle 17A as an anti-slip portion. In this embodiment, the zippers described later have the same structure.

[0050] like Figure 2 As shown, a side pocket 43 is provided on one side of the bag body 2 for storing the power cord of the measuring instrument, etc. The upper portion of the side pocket 43 can be opened and closed by a zipper 19. Furthermore, a small pocket 21 is provided on the surface of the side pocket 43. This small pocket 21 does not have a zipper, allowing for quick insertion and removal of items.

[0051] Moreover, if Figure 1 as well as Figure 3 As shown, a cloth 20 and a pressing unit 60 are provided on the other side of the bag body 2 opposite to the side pocket 43 for fixing objects of a length such as a measuring rod that cannot be placed in the front pocket 16 and the side pocket 43 to the bag body 2. This will be described in detail later.

[0052] like Figure 4A 、 Figure 4B As shown, the back of the bag body 2 features a terminal storage section 29 for storing a portable information terminal such as a tablet or laptop computer, which serves as a remote control device for the measuring instrument. A zipper 27 is attached to the terminal storage section 29, allowing the portable information terminal to be inserted and removed. The terminal storage section 29 is made of polyurethane or sponge, providing overall cushioning, enhancing the user's wearing comfort. It also protects not only the portable information terminal but also the measuring instrument within the storage space from the back.

[0053] like Figure 3 As shown, the bottom surface of the bag body 2 has a plurality of anti-slip portions 36. The anti-slip portions 36 are made of rubber and, through their grip, prevent slipping and absorb shock when the backpack 1 is placed. Each anti-slip portion 36 is composed of a pair of blocks 36B, 36B and a central groove 36A sandwiched between the pair of blocks 36B, 36B.

[0054] The anti-slip portion 36 is composed of a first anti-slip portion 37 having a groove 36A extending in the left-right direction and an anti-slip portion 38 having a groove extending in the front-back direction, thereby preventing sliding in the front-back and left-right directions.

[0055] Next, the overall structure of the mat 4 will be described.

[0056] As described above, in the backpack 1, the terminal storage portion 29 (see Figure 4A 、 Figure 4B ) to protect the back of the measuring instrument. Figure 1 As shown, the backpack 1 has a first pad 46 (see FIG. 4 ) that contacts the peripheral side and bottom surfaces of the measuring instrument and is used to protect the left and right side surfaces, the front surface, and the bottom surface. Figure 6 ) and a second mat 45 for protecting the top surface (see Figure 6 Thus, the mat 4 of this embodiment protects all six surfaces of the measuring instrument TD, including the terminal storage portion 29, the first mat 46, and the second mat 45. The first and second mats 45, 46 are formed of shock-absorbing materials such as sponge or polyurethane. The first and second mats 45, 46 will be described in detail later.

[0057] Next, the overall structure of the cover 5 will be described. Figures 1 to 4B Most of the area is covered by the storage box 25 described later, so it is also appropriate to refer to the cover 5 opened. Figure 6 Provide explanation.

[0058] Figure 1 as well as Figure 2 The cover 5 is a lid covering the storage space S of the bag body 2. In order to be able to be turned over in the R direction (the direction of the front side), a flexible member made of nylon or polyester fiber fabric is used as a base. In addition, when the storage space S is covered by the cover 5, the top surface opening 30 (see Figure 6 ) area, is connected to a storage box 25 for storing measuring components or accessories such as prisms.

[0059] The storage box 25 has a lid 51 that can be opened and closed by a zipper 26. The zipper 26 is only provided on the left and right side surfaces and the back surface, and the lid 51 can be opened in the R direction similarly to the cover 5 with the front surface as a fulcrum.

[0060] Next, the overall structure of the shoulder strap 8 will be described.

[0061] The shoulder strap 8 is called a shoulder harness, a shoulder belt, etc. Figure 2 as well as Figure 4A 、 Figure 4BAs shown, a pair of shoulder straps 8 are provided on the back, worn on the left and right shoulders. Each shoulder strap 8 has an upper end 8A connected to the bag body 2, and a lower end 8B connected to the left and right sides of the lower portion 2A of the bag body 2 via webbing 41. Furthermore, a waist belt 44 is provided on the back of the backpack 1 via webbing 42 sewn to the lower portion 2A of the bag body 2. The waist belt 44 is adjustable in length. A looped handle 28 is also provided on the back.

[0062] The backpack 1 described above also has the following features.

[0063] Storage Box

[0064] Figure 5 The present invention relates to a storage box 25 for storing prisms and other components. The top view thereof is observed with its lid 51 opened. A plurality of prism storage sections 14 (three in the figure) for storing prisms PM are arranged inside. The prism PM is used to receive laser light from the measuring instrument and return it to the measuring instrument. Each prism storage section 14 is separated from other spaces by a first and a second partition 13, 53 having a buffering property. The first partition 13 and the second partition 53 are orthogonal to each other and are connected in a movably manner by means of Velcro 52, 33 so as to be detachable. In this way, the prism PM is pressed into each prism storage section 14 by the first and the second partitions 13, 53 for protection.

[0065] The storage box 25 of this embodiment can also accommodate a battery BT and a charger CH. To prevent the battery BT and charger CH from adversely affecting the prism PM, their movement is restricted by a second partition plate 53 and a wall 54. The wall 54 is also movably connected by a hook and loop fastener 55.

[0066] A core material (not shown) made of a thin plate or a high-hardness cushioning material is placed inside the outer wall of the storage box 25. Figure 5 The left and right side surfaces 25A and the front surface 25C shown and Figure 2 The back surface 25B shown has appropriate rigidity. Therefore, even if the cover has flexibility, the flexibility of the area where the storage box 25 is connected is substantially eliminated.

[0067] In addition, Figure 5 The illustrated storage box 25 has a net 57 disposed on the inner side of the lid 51 .

[0068] Moreover, if Figure 2As shown in the figure surrounded by a single dotted line, the upper surface (cover 51) of the storage box 25 is an inclined surface that tilts downward toward the front side when covering the storage space. The inclination angle θ1 of the inclined surface in the figure relative to the horizontal direction is about 20 degrees, but the present invention is not limited to this, and it can also be any range of 10 to 45 degrees. Therefore, even if a small stone or the like falling from above hits the storage box 25, its impact can be mitigated, and the measuring components in the storage box can be effectively protected. In addition, even if it rains, the rain can flow quickly to the front side to prevent the components therein and the user's back from getting wet.

[0069] In addition, the color of the left and right side surfaces 25A of the storage box 25 is more conspicuous than the surroundings. In the case of this embodiment, the surroundings of the left and right side surfaces 25A of the storage box 25 are black or gray, and the left and right side surfaces 25A are yellow. Yellow is one of the most conspicuous colors in the backpack 1. Figure 6 By turning the cover 5 upside down and opening it in this manner, the user can avoid contact with the left and right side surfaces 25A of the storage box 25 when putting in and taking out the measuring instrument TD.

[0070] [Opening, cover, and storage box]

[0071] like Figure 6 As shown, the bag body 2 includes a top opening 30 connected to the storage space S and a front opening 32 , which constitute an opening serving as an entrance and exit for the laser measuring device DT.

[0072] The top opening 30 is located on the top surface (upper surface) of the bag body 2. The top opening 30 in the figure has a substantially quadrilateral shape when viewed directly, and is inclined downward toward the front side.

[0073] The front opening 32 is formed in a portion of the front surface of the bag body 2. Since it is continuous with the top opening 30, at least the upper portion of the front surface is open. The front opening 32 in the figure is generally rectangular when viewed from the front, extending from the center of the bag body 2 in the height direction to both the left and right ends. This wide opening area facilitates the insertion and removal of the laser measuring device DT.

[0074] The cover 5 covering the top opening 30 and the front opening 32 can be turned over and opened with the lower peripheral edge 32A of the front opening 32 as a fulcrum to expose the storage space S. Specifically, the cover 5 is fixed to the bag body 2 at the lower peripheral edge 32A of the front opening 32, but the other edges can be opened and closed. Figure 1 as well as Figure 2The left and right side zippers 12 and the back zipper 18 are opened and closed. The left and right side zippers 12 are composed of a first zipper 12A between the side and top surface of the bag body 2 and a second zipper 12B between the side and front surface.

[0075] Among them, Figure 6 As shown, because the fulcrum for opening the cover 5 is the lower peripheral edge 32A of the front opening 32, when the cover 5 is opened, the storage box 25 attached to the cover 5 will hit the ground or floor, etc., and this impact may adversely affect the prisms and other components inside. However, cushioning material 50 is provided on the outer wall of the storage box 25 in the area where the bag body 2 touches the ground when the cover 5 is opened. This can mitigate the impact of the impact with the ground, etc., effectively preventing damage to components.

[0076] In the case of this embodiment, the front end portion of the storage box 25 on the opposite side of the lower peripheral portion (support point) 32A (at the portion where the cover 5 covers the storage space) is Figure 2 The back side 25B of the storage box 25 in the state is provided with a plurality of cushioning materials 50, 50. Moreover, the lower peripheral edge portion (support point) 32A is arranged in such a manner that the cushioning materials 50, 50 touch the ground when the cover 5 is opened. Figure 1 As shown, the second zipper 12B between the side surface and the front surface of the bag body 2 is not arranged below the fulcrum.

[0077] Figure 2 Each cushioning material 50 is made of rubber and has a pair of blocks 50B, 50B and a central groove 50A sandwiched between the blocks 50B, 50B. This facilitates deformation of each block 50B, thereby improving the cushioning effect and grip. Furthermore, the groove 50A is formed in the left-right direction, thereby improving the grip in the front-back direction.

[0078] 〔First and second mat〕

[0079] Main Use Figure 6 as well as Figure 7 The first and second cushions 45 and 46 will be described. Figure 6 This is a perspective view of the state in which the cover 5 is opened, and the state thereof is visually recognized through the side surface of the bag body 2 and the measuring instrument TD. In addition, a zipper and the like are also omitted. Figure 7 This is an explanatory diagram of the attachment and detachment structure of the first cushion 46 with respect to the bag body 2 , in which the left and right side surfaces of the bag body 2 are made transparent, and the cover 5 and the front surface are omitted.

[0080] like Figure 6 As shown, the backpack 1 includes a first pad 46 that contacts at least the peripheral side surface of the measuring device TD and a second pad 45 that presses the head of the measuring device TD from above.

[0081] First, the first cushion 46 will be described. The first cushion 46 of this embodiment is a cushioning material that contacts the left and right side surfaces, the front surface, and the bottom surface of the measuring instrument TD and protects the above structure. That is, in the first cushion 46, the back surface of the six surfaces of the measuring instrument TD is left as the cushion for the terminal storage portion 29 (see Figure 4A 、 Figure 4B ), leaving the upper surface for the second pad 45 to protect the other surfaces. Figure 7 As shown, the first mat 46 includes side protection portions 46B and 46C for protecting the left and right sides of the measuring instrument TD, a front protection portion 46D for protecting the front, and a bottom protection portion 46E for protecting the bottom. These protection portions 46B, 46C, 46D, and 46E are integrally formed.

[0082] In addition, the first cushion 46 fits tightly against the contained measuring instrument, and the surface is covered with smooth cloth for easy insertion and removal.

[0083] like Figure 6 As shown, when attached to the bag body 2, the first cushion 46 preferably has at least its front-side upper surface 46A positioned at or below the fulcrum (i.e., the lower peripheral edge 32A of the front opening 32) when the cover 5 is opened. This prevents the first cushion 46 from obstructing the insertion and removal of the measuring instrument TD. In the illustrated embodiment, the upper surface 46A is positioned at the same level as the fulcrum (lower peripheral edge 32A) when the cover 5 is opened, and remains at the same level all the way to the upper surface of the rear side.

[0084] In addition, the first cushion 46 is configured to guide the battery (not shown) of the measuring instrument TD to be arranged on the back side of the storage space S. For example, in the case of the measuring instrument TD in the figure, the back side has a pair of handles HA, HA, and a heavy battery is provided near the lower side of the handles HA, HA. In addition, the distance between the pair of handles HA, HA is larger than the distance between the left and right sides of the measuring instrument body. The measuring instrument TD has such a shape, so the distance W on the back side between the side protection portion 46B on the left side and the side protection portion 46C on the right side of the first cushion 46 is the largest. Therefore, the user places the handle HA on the back side, thereby being able to naturally place the heavy battery near the back.

[0085] Such a first mat 46 is detachable and can be replaced in accordance with various measuring instruments, so its detachable structure will be described.

[0086] like Figure 7As shown, strip-shaped members 47, 47 are provided on the left and right side surfaces of the first mat 46. Only the upper end portion 47A of each strip-shaped member 47 is sewn to the upper side surface of the first mat 46, and the other end portion 47B is a free end. Moreover, the lower portion of the left and right side surfaces of the first mat 46 has a Velcro 48 that can load and unload the other end portion 47B of the strip-shaped member 47. In contrast, a belt 59 having only two end portions 59A sewn in the front-to-back direction is provided on the inner surface of the left and right side surfaces of the bag main body 2. By constructing such a structure, the free end, i.e., the other end portion 47B of the strip-shaped member 47 of the first mat 46 can be passed between the inner surface of the left and right side surfaces of the bag main body 2 and the belt 59, and thereafter, the other end portion 47B is mounted on the Velcro 48, as shown in FIG. Figure 6 As shown, the first cushion 46 is fixed in the bag body 2 .

[0087] As described above, since the first cushion 46 is detachable, it can be used with, for example, Figure 8 The first pad 146 is replaced with the shape shown. Figure 8 In the case of the first mat 146, it corresponds to the measuring instrument TD2 in which the measuring instrument body is substantially cylindrical and a battery BT protrudes from a portion of its back surface. That is, the first mat 146 is provided with a notch 70 corresponding to the battery BT on the back surface. Figure 8 In this case, the heavy battery BT is naturally arranged on the back side.

[0088] Next, mainly use Figure 6 The second cushion 45 will be described.

[0089] The second cushion 45 is not a thin plate as a whole, but rather a block-shaped structure with a predetermined thickness. The second cushion 45 is connected to the area AR indicated by the dashed line on the lower surface 5A of the cover 5 when the cover 5 covers the storage space S. In this embodiment, the second cushion 45 includes a cushion body 80 made of a cushioning material such as polyurethane, and a plate-like portion 81, which is at least harder than the cushion body 80 and is located on the side connected to the cover 5. In this embodiment, the plate-like portion 81 is a plastic plate.

[0090] If the cover 5 is opened again to cover the top opening 30 and the front opening 32, the second cushion 45 follows the cover 5 and is placed on the Figure 6 Moreover, if the zipper 12, 18 (refer to Figure 1 、 Figure 2 ) When the cover 5 is closed, the second cushion 45 is effectively pressed against the head of the measuring instrument TD, thereby fixing the measuring instrument TD and absorbing the impact.

[0091] The second cushion 45 is shaped so that when the top opening 30 and the front opening 32 are covered by the cover 5, Figure 6The one-dot chain line in FIG. 1 shows a shape that avoids the antenna AT protruding above the measuring instrument TD, and the right side of the figure is missing.

[0092] The upper surface (the surface on the plate-shaped portion 81 side) 45A of the second cushion 45 in the state covered with the cover 5 is an inclined surface that is inclined downward toward the front side. Figure 2 The inclination angle θ1 of the cover 51 of the storage box 25 is the same, and the inclination of the cover 51 is supported.

[0093] Figure 6 The second pad 45 can be attached and detached by means of a hook and loop fastener 65 provided on the lower surface 5A of the cover 5 (the surface arranged on the side of the storage space S). In order to be able to replace and connect a pad corresponding to another measuring instrument, a hook and loop fastener 65 is also provided in the area other than the area AR indicated by the dotted line on the lower surface 5A of the cover 5. Figure 6 The second mat shown is 45 large Figure 8 The second cushion 145 shown can also be connected to the lower surface 5A of the cover 5. Figure 8 The second pad 145 has a through hole 145A at its center. The through hole 145A is a hole for avoiding the antenna of the measuring instrument.

[0094] Figure 6 The second cushion 45 is constructed as above, so if the cover 5 is closed, the measuring instrument TD is pressed from the head for protection. Figure 6 When the cover 5 is opened, the second cushion 45 also protects the front side of the storage box 25. Furthermore, when the cover 5 is opened, the back side of the storage box 25 is protected by the first cushion 46, and the bottom side is protected by the cushioning material 50. Furthermore, the left and right side surfaces of the storage box 25 are a more conspicuous color (yellow in this embodiment) than the surrounding color (black in this embodiment), which attracts the user's attention and prevents being kicked, etc.

[0095] 〔Side view of the bag〕

[0096] like Figure 1 as well as Figure 3 As shown, a cloth 20 for holding a long object such as a spindle in the bag body 2 and a pressing unit 60 for freely pressing the cloth 20 are provided on one side surface of the bag body 2 .

[0097] The cloth 20 is a flexible woven or nonwoven synthetic fiber fabric. Only its two front-to-back ends 20A, 20A, are sewn to the bag body 2. When laid flat, the cloth 20 has a generally rectangular shape, with a length greater than the front-to-back length D1 of the side surface of the bag body 2. When not in use, the cloth 20 is folded and stored sideways. Furthermore, in this embodiment, at least the inner surface (the surface facing the side surface of the bag body 2) of the cloth 20 is knitted with a textured feel.

[0098] The pressing unit 60 is a component that presses and releases the cloth 20 and a long object to be held. Specifically, the pressing unit 60 is adjustable in length and consists of a pair of upper and lower straps. Each strap is equipped with a buckle 61, which allows the cloth 20 to be pressed sideways freely by attaching and detaching the buckle 61.

[0099] The side of the bag body 2 is such a structure, so if the buckle 61 is removed, for example Figure 3 The cloth 20 is unfolded as shown by the single-dot chain line, and a measuring rod or the like is inserted between the cloth 20 and the side of the bag body 2 to hold the object. Then, the length of the pressing unit (belt) 60 is adjusted and the buckle 61 is fastened. Since the cloth 20 is flexible, the shape of the cloth 20 can be changed to follow the shape of the long object (fixed object) while cooperating with the pressing unit 60 to fix the long object.

[0100] In addition, the pressing unit 60 of this embodiment is composed of a belt with a buckle, but the present invention is not limited to this, and it may also be a rubber belt. Figure 3 The cloth 20 shown by the one-dot chain line is a diagram showing the cloth 20 being maximally expanded. However, when inserting the object to be held, the cloth 20 does not need to be maximally expanded.

[0101] The above describes the embodiments of the present invention. However, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the claims. The structures of the above embodiments can be omitted or combined in any manner different from the above.

[0102] For example, the first cushion 46 of this embodiment serves as a cushioning material for protecting the left and right sides, front, and bottom of the measuring instrument. Other cushioning materials may also be fixed to the bottom of the bag body 2, and the first cushion only protects the left and right sides and front of the measuring instrument.
