Description

  The present invention relates to a tool holder for carrying a tool at a work site such as a construction work.

  At work sites such as construction work, electrical work, and civil engineering work, there are many tool holders that attach a bag-like or box-like container to the operator's waist using a belt, etc., for workers to carry tools. Has been.

  Such tool holders are generally open at the top, and are easy to put in and out of the tool, but when the user's upper body is tilted, the opening faces downward and is stored. There was a problem that the tool that had been dropped. If a lid covering the opening is provided, the falling of the tool can be suppressed, but this makes it difficult to put in and out the tool. In other words, conventionally, the ease of putting in and out of tools and the difficulty of dropping tools have been incompatible.

  Therefore, a tool holder has been proposed that is intended to allow the tool to be easily taken in and out while covering the upper part of the container (see Patent Document 1). In this case, a circular opening is provided in a cover covering a box-shaped container, and the opening is sealed with a plurality of flexible tongue pieces that are radially cut and separated from each other. . With this configuration, by inserting the user's hand into the opening, it is possible to widen the gap between the flexible tongue pieces, and to insert and remove the tool. It becomes resistance to being pulled out together and falling.

  However, in the conventional tool holder described above, since the container is covered with a cover and the opening is also covered with a tongue, it is difficult to visually recognize the tool contained in the container. Also, tools longer than the depth of the container cannot be accommodated because they interfere with the cover. Furthermore, the tool has to be taken in and out by widening the gap between the tongue pieces through an opening of limited size, and the work efficiency is low. In the case of the flexible tongue, when the user's upper body is tilted and the opening portion is directed downward, the tool may not be able to resist the fall of the tool due to gravity.

JP 2009-45677 A

  Therefore, in view of the above circumstances, the present invention has an object to provide a tool holder in which a tool to be carried is easy to put in and out, and the contained tool does not easily fall regardless of the posture of the user.

  In order to solve the above-described problems, the tool holder according to the present invention includes a container that opens upward, a mounting portion that is mounted on the waist of a user, and the container and the mounting portion that are rotatably connected to each other. And a pivotal connecting portion.

  The “container” is a part that accommodates the tool, and can be a box shape or a bag shape having rigidity. Moreover, it can also be set as the container of the structure which has the pocket which can further accommodate a tool in the structure by which the inside of the container was divided by the partition, or the outer part of the box shape etc. which accommodate a tool.

  Examples of the “mounting part” include a ring-shaped member through which the belt is inserted, a belt body that can be engaged with both ends with a hook-and-loop fastener after crossing the belt, and a belt loop of trousers and a hook that is hooked on the belt Can do. There may be a plurality of these mounting portions, and the plurality of mounting portions may be attached to a base portion such as a flat plate.

  Examples of the “rotating connection portion” include a configuration including a pair of flat plate members that slide relatively along a circular track. Here, as a mode of sliding relatively along the circular track, the inner peripheral edge of the circular hole provided in one of the pair of flat plate members, and the outer peripheral edge when one outer shape of the flat plate member is circular Or a slidably fitted circular or arc-shaped projecting piece on the other flat plate member, a circular groove provided on one of the pair of flat plate members, and the other A mode in which a circular or arc-shaped protrusion provided on the flat plate member is slidably fitted can be exemplified. In addition, the “rotation connecting portion” may be a shaft portion that fastens the mounting portion with respect to the container in place of the above configuration. In this case, the mounting portion is provided with a base portion, the mounting portion is fastened to the container via the base portion with the shaft portion, the container is attached with the base portion, and the shaft portion is attached to the container via the base portion. An example of a structure that is fastened, or a structure that has both a base part to which a mounting part is attached and a base part to which a container is attached, and the mounting part and the container are fastened by a shaft part via two base parts. can do.

  In this configuration, the tool is easy to put in and out because the container opens upward. Moreover, since it does not have the part which obstruct | occludes the upper direction of a container, the tool accommodated in the container is easy to visually recognize. Furthermore, since the container is opened upward, a tool longer than the depth of the container can be accommodated. In addition, in this configuration, the container freely rotates with respect to the mounting portion fixed to the user via the rotation connecting portion. Therefore, even if the upper body of the user is tilted and the mounting portion is tilted along with this, the container does not follow it and rotates by its own gravity, so that the opening remains facing upward. Therefore, even if the posture of the user changes, the opening of the container does not face downward and always faces upward, so that the stored tool is prevented from falling. Thus, according to this configuration, it is possible to achieve both ease of taking in and out of the tool and difficulty of dropping the tool.

  The tool holder according to the present invention has the above-described configuration, wherein “the rotation coupling portion is concentric with the track between a pair of flat plate members that slide relative to each other along a circular track and the pair of flat plate members. And a plurality of rolling elements arranged in the orbit space ”.

  As the “orbital space”, circular grooves each having a circular arc shape or a U-shape are provided concentrically and with the same diameter on the facing surfaces of a pair of flat plate members, and one space is formed by the grooves on both sides. Can be exemplified. Moreover, the aspect by which the circular groove | channel was provided only in one side of a pair of flat plate member, and the space was formed between the other flat plate members may be sufficient. A plurality of “orbit spaces” may be concentric with the circular orbit.

  As the “rolling element”, a rotating element having a circular cross section in the circumferential direction of the orbital space, such as a spherical shape, a cylindrical shape, or a spindle shape, can be used.

  In this configuration, the pair of flat plate members of the rotation connecting portion slide relative to each other along the circular track, so that the container and the mounting portion are rotatable with respect to each other. That is, the rotation connecting portion does not have a shaft portion. Here, in the configuration having the shaft portion, since the load of the tool accommodated in the container is concentrated on the shaft portion, it is necessary to make the shaft portion high in strength, and the shaft portion is supported in the container and the mounting portion. The part must also be of high strength. On the other hand, in this structure, since the container and the mounting part are connected by a pair of flat plate members, the portions where the pair of flat plate members are respectively attached to the container and the mounting part receive a load on the surface. Thereby, since the load is dispersed, the container and the mounting portion can be rotatably connected without the need to particularly strengthen the portion where the pair of flat plate members are attached in the container and the mounting portion.

  Further, in this configuration, the rolling resistance rolls between the opposing surfaces of the pair of sliding flat plate members, so that the frictional resistance is greatly reduced. Thereby, a container can be smoothly rotated with respect to a mounting part.

  As described above, as an effect of the present invention, it is possible to provide a tool holder in which a tool to be carried can be easily taken in and out and the contained tool is difficult to fall regardless of the posture of the user.

They are (a) the perspective view seen from the container side of the tool holder which is one Embodiment of this invention, and (b) the perspective view seen from the mounting part side. FIG. 2A is an exploded perspective view of the tool holder of FIG. 1, and FIG. 2B is an exploded perspective view of a rotation connecting portion. It is explanatory drawing of operation | movement of the rotation connection part in the tool holder of FIG.

  Hereinafter, a tool holder 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The tool holder 1 according to the present embodiment includes a container 10 that opens upward, a mounting part 20 that is mounted on the waist of a user, and a rotation connecting part 30 that rotatably connects the container 10 and the mounting part 20 to each other. And.

  In the above-described configuration, the rotation connecting portion 30 includes a pair of flat plate members 31 that slide relatively along a circular track, and a track formed between the pair of flat plate members 31 in a circular shape concentric with the circular track. And a plurality of rolling elements 35 disposed in the orbit space.

  More specifically, the container 10 is a substantially rectangular parallelepiped having an opening 11 opened upward, one side surface is a flat plate-shaped container plane portion 12, and the other three side surfaces are lower than the container plane portion 12. It has a U-shaped cross section with rounded corners on three sides. The mounting portion 20 includes a flat plate-like base portion 21 and two ring-shaped members 22 attached side by side with the base portion 21.

  The pair of flat plate members 31 of the rotation connecting portion 30 are formed in a square having the same size, and a circular hole 32 having the same size is provided on both sides. One of the pair of flat plate members 31 has a protruding piece 33 rising along the inner periphery of the circular hole 32, and the protruding piece 33 overlaps with the inner peripheral edge of the circular hole 32 of the other flat plate member 31 and is loosely fitted. Thus, the pair of flat plate members 31 are slidably coupled. That is, a circular track is formed by the inner peripheral edge of one circular hole 32 of the pair of flat plate members 31 and the protruding piece 33 loosely fitted thereto.

  Furthermore, circular grooves 34 having the same arc diameter and the same diameter are formed on the facing surfaces of the pair of flat plate members 31. Each of these circular grooves 34 is concentric with the circular hole 32. Then, when the pair of flat plate members 31 face each other, a circular orbit space is formed by both the circular grooves 34. In this orbit space, twelve spherical rolling elements 35 and a ring-shaped retainer 36 are arranged. The retainer 36 is provided with the same number of holes 37 as the rolling elements 35 at regular intervals, and the rolling elements 37 are rotatably inserted into the holes 37 one by one. As a result, the plurality of rolling elements 35 roll in the orbital space in a state where the spacing is maintained by the retainer 36.

  One of the pair of flat plate members 31 is attached to the container flat surface portion 12 of the container 10, and the other flat plate member 31 is attached to the base portion 21 of the mounting portion 20.

  Next, the usage method and operation | movement of the tool holder 1 are demonstrated. First, the belt 40 is inserted into the ring-shaped member 22, and the belt 40 is attached to the user's waist. Thereby, the mounting part 20 is mounted | worn with a user's waist | hip | lumbar part. And a tool can be carried by accommodating a tool (not shown) in the container 10.

  When the user tilts his / her upper body from the state where the user is raising his / her upper body (see FIG. 3A), the mounting portion 20 mounted on the user's waist is also tilted. Along with this, the flat plate member 31 attached to the mounting portion 20 of the pair of flat plate members 31 is also inclined. On the other hand, in the container 10 to which the other flat plate member 31 is attached, gravity acts on the container 10 itself and the tool accommodated in the container 10. Therefore, the flat plate member 31 on the container 10 side maintains the same posture by rotating relative to the flat plate member 31 on the mounting portion 20 side along a circular track. At this time, the rolling elements 35 roll in the orbit space concentric with the circular orbit, so that the pair of flat plate members 31 smoothly rotate relatively. In this way, the flat member 31 on the container 10 side maintains the same posture without being inclined following the flat member 31 on the mounting part 20 side, so that the container 10 is always maintained with the opening 11 facing upward. (See FIG. 3B). In FIG. 3, the flat plate member 31 on the container 10 side is shown by a solid line in order to clearly show the configuration.

  As described above, according to the tool holder 1 of the present embodiment, even if the posture of the user changes, the opening 11 of the container 10 does not face downward and is always directed upward, so that it is accommodated. The fall of the tool is suppressed. Moreover, since the container 10 has the opening part opened upwards, it is easy to take in and out of a tool, it is easy to visually recognize the tool accommodated in the container, and a tool longer than the depth of a container can be accommodated. .

  In addition, since the pair of flat plate members 31 are relatively slid along the circular track as the rotation connecting portion, the load applied to the container 10 is transferred to the container of the container 10 via the flat plate member 31. The flat portion 12 and the base 21 of the mounting portion 20 are received by the surface. Thereby, since the load is dispersed, the container 10 and the mounting part 20 can be rotatably connected without the container flat part 12 and the base part 21 having a very strong configuration.

  Furthermore, in the tool holder 1, the plurality of rolling elements 35 roll in a raceway space formed between the facing surfaces of the pair of sliding flat plate members 31, so that the relative rotation of the pair of flat plate members 31 is achieved. The frictional resistance accompanying movement is reduced.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  For example, in the tool holder 1 of this structure, the structure which restrict | limits the range which the mounting part 20 and the container 10 rotate can also be added. As such a configuration, in the pair of flat plate members 31, locking pieces are respectively provided on the inner peripheral edge of the circular hole 32 serving as a circular track and the circular protruding piece 33, and the locking piece is provided in the middle of the slide. The structure which mutually engages can be illustrated. As a result, it is possible to prevent the tool from dropping due to the container unintentionally pivoting unintentionally, such as when a surrounding object is inadvertently in contact with the container.
