Description

  The present invention relates to a tool bag, and more particularly to a tool bag used to lift or suspend a tool or tool necessary for working at a high place in civil engineering, construction, electrical work, piping, or other work.

  Conventionally, a tool bag (commonly called “bucket”) in which both ends of a hanging strap are tied (fixed) to the mouth of a cylindrical bag has been used. The tool bag has a diameter of 200 mm to 320 mm, a height of 300 mm to 1500 mm, and accommodates tools and other parts (single pipe, joint parts, etc.) such as a spanner, a wrench, and a hammer and can be used. Is assumed to be 35 kg to 80 kg, and the breaking load is set to 7.3 N to 16.75 N. Therefore, strength is dealt with in consideration of the breaking load so that the belt is not cut or the bag is not torn.

  Since the tool bag is a conventional suspension structure with a single belt, the strength of the belt is the first point of attention, but in consideration of safety, in addition to the belt, the belt and the bag mounting portion, Consideration of strength is required for the cylindrical portion, the bottom of the bag, and the like.

  Since the conventionally known tool bag bears the entire weight of one belt (Patent Documents 1 and 2), there is a possibility that danger may immediately occur if a failure occurs in the belt. Further, since the bottom portion of the tool bag was not considered, there was a possibility that the tip of the tool hits and the tool might break through the bottom of the tool bag due to gravity.

  Moreover, although the bottom part of the tool bag is easy to come into contact with other objects and easily wears, no measures against wear have been taken.

  Further, since the tool bag is lifted to a high place or hung from a high place, the tool bag is subjected to gravity every time it is used, and a force larger than the weight may be applied rapidly, but no countermeasure has been taken.

  In addition, tool bags are used on construction sites under continuous and harsh conditions, so it is anticipated that tools exceeding the load capacity will be packed, and rapid speed changes will occur when lifting or hanging. There was a problem that no measures were taken.

  This device has solved the above problems as follows. That is, in the past, a single belt was normal, but this was hung with two belts to double the strength of the support when lifting, and both belts were turned to the bottom of the tool bag. The entire weight was supported by two belts.

  In addition, a reinforcing plate (for example, a thin metal plate) is accommodated in the inner bottom portion of the cylindrical bag, and the reinforcing plate is reinforced by providing a rising line on the solid line of the reinforcing plate. The bottom plate was prevented from being damaged even if it was dragged sideways.

  In addition, the two belts are configured such that a plurality of different color belts are overlapped, and a different color appears when the belt on the surface is partially worn, and the belt usage limit is automatically notified.

  In addition, since the mouth portion and the bottom peripheral portion of the cylindrical bag were reinforced by double sewing, it was considered that the portion had double strength and that the original strength did not decrease even if it was worn down.

  In addition, four protrusions were arranged on the bottom lower surface to serve as support protrusions at the time of placement to prevent contact between the bottom surface of the bag body and the floor surface.

  That is, the present invention installs both ends of the two belts at equal intervals on the outer wall and the bottom wall of the cylindrical bag, and accommodates a bottom plate on the inner bottom of the cylindrical bag. Is a tool bag characterized by intersecting at the top and bottom of the cylindrical bag.

  Further, both end portions of the two belts are installed at equal intervals on the outer wall and the bottom wall of the cylindrical bag, and a bottom plate is accommodated on the inner bottom of the cylindrical bag, to the mouth edge of the cylindrical bag. The tool bag is characterized in that the two belts are installed and intersect at the top and bottom of the cylindrical bag.

  Further, both end portions of the two belts are installed at equal intervals on the outer wall and the bottom wall of the cylindrical bag, and a bottom plate is accommodated on the inner bottom of the cylindrical bag, and the two belts are cylindrical. It is a tool bag characterized in that four synthetic resin protrusions are provided at equal intervals on the bottom surface of the bottom, intersecting at the top and bottom of the bag.

  Further, both ends of the two belts are equally spaced from the outer wall and the bottom wall of the cylindrical bag, and a bottom plate is accommodated on the inner bottom of the cylindrical bag, and the two belts are connected to the cylindrical bag. A tool bag characterized in that the belt has a plurality of layers, and the outer layer and the inner layer have different colors.

  Further, both ends of the two belts are equally spaced on the outer wall and the bottom wall of the cylindrical bag, and a bottom plate is accommodated on the inner bottom of the cylindrical bag, to the mouth edge of the cylindrical bag, The two belts intersect at the top and bottom of the cylindrical bag, and four synthetic resin protrusions are provided at equal intervals on the bottom bottom surface, the belt has a plurality of layers, and the outer layer and the inner layer have different colors. It is a tool bag characterized by.

  Further, the belt has three or four layers of different colors, and the front and back layers and the middle layer have different colors.

  The bottom plate was a metal plate or a synthetic resin plate whose peripheral edge was raised by 30 to 90 degrees. The belt can also be reinforced with a metal wire.

  According to this device, both ends of the two belts are fixed to the outer wall and the bottom wall of the cylindrical bag, respectively, and when the cylindrical bag is suspended, the stability is good and the total weight is supported by the two belts. The balance against suspension load is improved.

  Further, the bottom plate can receive an external force applied to the bottom of the tool bag and can prevent the bottom plate from being damaged by a tool or the like.

  Furthermore, since it is possible to detect whether or not the tool bag can be used continuously due to damage to the belt, safe use can be expected.

  The rising angle of the peripheral edge of the bottom plate is 30 to 90 degrees, preferably 60 to 90 degrees. Therefore, it is possible to prevent the tool end from deviating outside the bottom plate.

  According to this device, since two suspension belts are used, the strength of the conventional suspension belt is ensured to be twice or more, and the stability is increased. Therefore, even when the weight of the contents exceeds the expected weight (nearly twice), it can be sufficiently tolerated.

  Further, since the bottom plate is accommodated to form a double bottom, there is an effect that a tool can be prevented from being stuck in the bottom of the tool bag and perforated.

  Next, since the belt is made of a plurality of layers having different colors, the wear of the belt is quickly found, and there is an effect that the use limit can be immediately known.

  Moreover, since the mouth edge part and bottom edge part of the tool bag are double walls, there is an effect that the strength of the cylindrical edge part that is easily worn is doubled or more.

  Furthermore, since the protrusion is provided on the bottom, the contact between the bottom surface of the bottom and the floor surface is prevented, and there is an effect that wear of the bottom surface of the bottom of the cylindrical bag can be prevented.

  The addition of each structure has the effect of dramatically increasing the usable period of the cylindrical bag (10 to 100 times).

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

        (Embodiment 1)

  The tool bag of this device is constructed as follows. The upper rim of the cylindrical body 1 made of a tough woven fabric is provided with an annular upper lip 2 covered with leather, and the rim 2 is covered with a leather strip 2a. A lower rim 3 made of the same quality woven fabric is connected to the lower rim of the rim, and the peripheral edge of the circular bottom 4 is sewn.

  Inside the bottom part 4, a bottom plate 6 having a rising edge 5 at the peripheral edge is installed (FIG. 2), and four protrusions 7 and 7 that are in contact with the floor surface etc. are evenly arranged on the bottom surface of the bottom part 4. And fix. The bottom plate 6 is a metal plate or a synthetic resin plate, but other materials can also be used.

Two belts 8 and 8 are arranged at equal intervals on the side surface of the cylindrical body 1, and are sewn and fixed at the upper and lower portions 9 and 9, respectively, and both edges in the longitudinal direction are sewn (FIG. 1).
The two belts 8 and 8 are arranged in a cross shape on the lower surface of the bottom portion 4, and the protrusions 7 and 7 are fixed to the fan-shaped exposed portion of the bottom portion 4. The upper portions of the belts 8 and 8 protrude above the mouth portion of the cylindrical body 1 to form intersections 10, and the belts 8a and 8a of the intersections 10 are bent to reduce the width so that hooks and the like can be easily hooked. is there. The tool bag 15 of the present invention was configured as described above.

  The belts 8 and 8 are formed by laminating woven belts 8a, 8b and 8c made of tough fibers, and the intermediate belt 8b is different from the outer belts 8a and 8c. For example, since the belts 8a and 8c are black and the belt 8b is red, when the outer belt 8a or 8c is worn, the red of the intermediate belt 8b can be seen. Therefore, if the red color is visible, it can be determined that the use has been stopped. Therefore, an unexpected accident can be prevented by replacing the tool bag with a new one. Since the lower part of the side wall of the tool bag is easily damaged, it is reinforced.

  Since the two belts are made of the same quality over the entire length, the danger can be immediately recognized even if somewhere weakens. Therefore, accidents due to band breakage can be prevented in advance. Moreover, there is no limitation on the number of laminated belt woven fabrics.

  Since the tool bag 15 has the two belts arranged evenly crossing the bottom plate, the weight of the tool bag 15 is applied to the two belts. Therefore, by setting the tensile strength of the two belts so that the maximum accommodation load can withstand the shock when the fall is stopped, safety can be ensured in any use method.

  Further, since the wear of the belt can be visually checked, the user can directly detect the danger and change the tool bag.

        (Embodiment 2)

  Another embodiment of the present invention will be described with reference to FIGS. 2 (d) and 2 (e). If the piano wires 14 and 14 are inserted between the woven fabrics 8a and 8b constituting the belt 8 or between 8b and 8c, the tensile strength of the belt 8 can be drastically improved. If the diameters of the piano wires 14 and 14 are determined in consideration of the tensile strength, the strength required for the belt can be obtained with certainty.

  In the above embodiment, two piano wires are inserted into the belt. However, even if a thin metal wire is woven into the woven fabric, the yield strength of the belt can be remarkably increased as described above.
