Description

  The present invention relates to a rucksack having a function of supporting a support object such as a drawing, a check list, or a sketch book.

  When a construction company staff visits a construction site for "Investigation of construction progress", "Investigation of defects", or "Consideration of repairs and modifications", record the information obtained at the site Therefore, necessary items are often written in drawings and checklists. In that case, conventionally, (a) a drawing, a check list and a board with a clip are accommodated in a bag, and these are carried into a construction site, and (b) the bag is placed in an appropriate place, and the drawing, the check list and the clip are placed. Take out the attached board, (c) place the drawing or checklist on the removed board with clip, and (d) write the necessary items in the drawing or checklist while moving the construction site. It was. Also, since bags are usually placed around the construction site, when other materials are needed during the work, (e) return to the place where the bag is placed and remove it from the bag. I tried to take out the materials. For this reason, conventionally, there is a problem in that work time is poor because it takes a long time to take in and out things (drawings, checklists, materials, etc.) from the bag. On the other hand, when working with a rucksack on the back, it is possible to save the trouble of returning necessary materials, etc., but when taking out the materials etc., the backpack must be taken down once, so the work efficiency is reduced. Could not be improved sufficiently.

  In order to solve such a problem, it is necessary to be able to quickly take out necessary materials from a bag (such as a rucksack) even during work, and Patent Document 1 satisfies this need to some extent. A “sketching bag” that can be used is disclosed. This "Sketch Bag" is equipped with a frame that forms the skeleton of the bag and a sketch board that can be detachably attached to the frame. By attaching the sketch board to the frame, work for placing a sketch book, etc. It constitutes a stand.

JP 2008-212602 A

  According to the “bag for sketching” in Patent Document 1, a work table can be configured by a frame and a sketch board, and a sketch book or the like can be placed on the work table to draw a picture. The bag is always located within the reach of the operator's hand, so that necessary materials can be quickly taken out from the bag. However, this "Sketch Bag" is designed to be used on the ground, etc., and the shoulder belt is "reversed" and the bag is worn in front of the body, moving around the site. However, it was not suitable for the intended use.

  That is, in the “Sketch Bag” of Patent Document 1, it is necessary to assemble the work table by fitting the hook member of the sketch board to the horizontal part of the frame, but the assembly work is performed in a “reverse” state. Is extremely difficult and has poor workability. Further, in the “reversed” state, the lid attached to the upper end opening of the bag covers the upper surface of the workbench, so that the lid interferes with the feeling of use.

  The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a rucksack that can improve workability and a feeling of use when used as a workbench in a state of “reversing”. And

  In order to solve the above-described problems, a rucksack according to the present invention includes a storage portion having a luggage compartment for storing a load, and a left and right integrally provided with the storage portion so as to be positioned on the back side of the storage portion. A pair of shoulder belts, a front opening provided in front of the accommodating portion, a blocking portion that seals the front opening so as to be openable and closable, a base portion disposed in the luggage compartment, and a rotation with respect to the base portion It is movably mounted and is configured to be switchable between a housed state housed in the cargo compartment and a projecting state projected from the front opening to the outside of the cargo compartment, and supports a support object in the projecting state. A rotation support part.

  In this configuration, when the rotation support portion is shifted from the “accommodated state” to the “projection state”, the front opening is opened and the rotation support portion is protruded from the front opening to the outside of the luggage compartment. Because it is a simple operation that only turns, even if the rucksack is worn in front of the body, the transition operation can be performed without any problem by turning the shoulder belt “in reverse”. In the “protruding state”, the rotation support part functions as a work table that supports the support object. For example, after placing the board with the clip as the “support object” on the rotation support part, the clip Necessary items can be written by putting drawings and checklists on the attached board. Further, if the rotation support portion is plate-shaped, a necessary item can be written by directly placing a drawing or checklist as a “support object” on the rotation support portion.

  On the other hand, when shifting from the “protruding state” to the “accommodating state”, the rotation support portion is rotated so as to be accommodated in the cargo compartment from the front opening portion, and the front opening portion is sealed by the blocking portion. In the “accommodating state”, since the base portion and the rotation support portion are accommodated in the cargo compartment, they do not protrude outside the accommodating portion, and the size during transportation can be reduced.

  One end is fixed to the plate-like member placed on the rotation support portion in the protruding state, and a fixing portion located at the center in the left-right direction of the plate-like member, and the other end is fixed to the left side portion of the base portion. The rotation support part, wherein the plate member is in the projecting state, and the first string is fixed to the fixing part and one end is fixed to the right side of the base part. The first string and the second string may be stretched without slack when placed in the regular position.

  In this configuration, when the plate-like member is placed at the normal position of the rotation support portion, the first cord and the second cord are stretched in a substantially V shape around the fixing portion, so that the fixing portion moves left and right. It is possible to prevent the plate-like member from undesirably moving and dropping from the rotation support portion. In addition, since the plate-like member placed on the rotation support portion can be turned around the fixed portion, the plate-like member can be used when writing necessary information by placing a drawing or checklist on the plate-like member. The member can be rotated in an easy-to-write direction together with the drawings and checklist.

  It may be provided with an annular neck belt which is provided at the upper part of the housing part and is hung on the user's neck.

  In this configuration, the weight of the rucksack can be borne on the neck by hanging the neck belt around the neck, so even if you turn the rucksack on your back in front of your body and put it in the `` back-hanging '' state The operation can be performed easily and quickly without taking down the rucksack.

  According to the rucksack of the present invention, the rotation support portion can be used as a work table simply by rotating the rotation support portion so as to protrude from the front opening to the outside of the luggage compartment. No special assembling work is required for the construction, and the preparatory work for use as a workbench in the “reverse hanging” state can be easily performed. Moreover, since the rotation support part protrudes from the front opening part to the exterior of the cargo compartment, even if a lid is attached to the upper end opening part of the housing part, the cover covers the upper surface of the rotation support part. In other words, it is possible to enhance the feeling of use when used as a workbench in the “reverse” state.
