Description

  The present invention relates to a work assist suit that assists a work such as bending and lifting a heavy load and carrying it with both arms in front of the body.

  In order to reduce the burden of work such as bending, lifting, holding and moving, a hard assist suit that supports muscle strength with the driving force of an actuator etc., and muscle strength is supported by the elasticity and repulsion of the material Some of the inner-type assist suits have already been put into practical use and supplied to the market.

  However, hard-type assist suits that use driving force require external energy such as batteries and actuators such as motors, so they tend to be large-scale and can be used in work environments where there is a lot of work involving sweating such as construction sites. In addition, the inner-type assist suit using the stretchability of the material has a problem that it is not suitable for work assist such as carrying and carrying heavy objects that require large muscle strength.

  In view of the above problems, the outer-type assist suit that can be easily worn like an apron even from the top of work clothes does not require a driving part like a hard-type assist suit, and is not troublesome to attach and detach. Since there is no problem that it is unsuitable for supporting heavy cargo handling work like an assist suit, it is suitable as a means for assisting work such as bending the baggage and carrying it with both arms.

  From the above viewpoints, those disclosed in Patent Documents 1 to 3 and the like have been proposed as outer-type assisting means for assisting operations such as holding the baggage and lifting it up in the past. .

  The conventional work assisting means for assisting the load holding work proposed in Patent Documents 1 to 3 includes a load support body having a substantially L-shaped cross section for supporting a load held with both hands from below, on a waist belt. It is installed and positioned on the front of the abdomen of the worker, and the front side of the bottom of the load held by both arms as seen from the worker is supported by the load support from below, but there is a problem to be solved .

Japanese Utility Model Publication No. 63-56105 JP 11-56473 A JP 2007-302448 A

That is, in the conventional work assist means shown in the above-mentioned patent document, the means for positioning the load support including the substantially L-shaped cross section for supporting the load held by both hands on the front surface of the abdomen is disclosed in the above-mentioned patent documents 1 and 2. As described in the above, it is a form in which a normal width (thin width) waist belt or other belt is connected to the load support body, so there is not only a function to reduce muscle fatigue, but also the weight of the load held. Sometimes bites into the worker's body through a thin belt and hurts muscles.
It is an object of the present invention to provide a hanger front type or best type work assist suit that has a good wearing feeling, has a function of reducing muscle fatigue, and is less likely to damage muscles.

  The configuration of the work assist suit of the present invention made for the purpose of solving the above-mentioned problem is a wide belt-shaped front portion that contacts a substantially entire area of the front and side surfaces from the chest to the abdomen of the operator with a required vertical width, A baggage support portion arranged with a convex portion on the front side of a substantially central portion of the front portion, a back belt portion connected to both left and right end portions of the front portion, and obliquely upward from left and right end portions of the front portion And a shoulder belt that crosses on the back side, passes through both shoulder portions of the operator, and is connected to be separated at a substantially center of the front portion.

In the above-described configuration of the work assist suit of the present invention, it is desirable to use a belt having a wide vertical width at the portion corresponding to the waist, and the back belt portion may be coupled to the front portion via a connecting belt. . Further, the required vertical width of the front part is, for example, at least about 30 cm to about 50 cm, preferably about 35 to 45 cm, most preferably about 40 cm, and the wide back belt part is about 20 to 30 cm. It can be a thing. Further, the front portion is preferably a woven fabric of nylon resin fibers, but may be a woven fabric or sheet fabric of other fibers.
The size of the front portion is such a size that the front and side regions of the wearer's chest and abdomen can be covered by the front portion, and the clothing and body can be protected from the luggage. Therefore, the numerical values of the front part and the types of fibers listed here are merely examples, and are not limited thereto.

  In the work assist suit of the present invention, the luggage support portion includes a core material holding portion for holding a core material by a cylindrical body or a rod-shaped body for forming a convex portion having a substantially L-shaped or substantially T-shaped side section. At least one woven fabric made of, for example, nylon resin fiber similar to the portion is formed and fixed to the front surface of the front portion by fastening or the like. Examples of the core material include a solid square bar, a round bar, or a hollow square pipe or a round pipe. In the present invention, the reason why the load supporting portion is separated from the front portion is to ensure the strength of the load supporting portion that is in direct contact with the load and the body adhesion of the front portion.

  At least two of the core material holding portions are provided in parallel in the horizontal direction, for example, so that the core material can be held at different heights in the vertical direction of the front portion. This is to change the support position of the load according to the difference in the physique of the worker. The core material holding part may have a shallow V shape in addition to the horizontal straight line shape.

  It is desirable that a flexible foam is stored as a cushion material as an example in at least one or both of the inside of the core material holding part or the inside of the front part facing the core material holding part. This is in order to prevent body corners such as the corners of the luggage held and supported from biting into the body, and to prevent contamination and damage of clothing due to the luggage held.

  The reason why the vertical width of the back belt portion is widened in the present invention is that when the heavy load is lifted by both arms, the wide belt is brought into close contact with the waist portion of the operator so that the waist portion is protected by the belt. .

  In the work assist suit of the present invention, the shoulder belt is pulled out upward from the left and right ends of the front portion, and the shoulder belt is crossed with the back and brought to the front side of the body through both shoulder portions, and the front portion is abbreviated. The central part is connected to the left and right sides in order to bring the front part into close contact with the abdomen from the chest of the operator in combination with the tightening of the back belt part and the weight of the luggage on the luggage support part. This is to convey effectively to the shoulder belt. For this reason, the said back belt part and the shoulder belt are each provided with the buckle (it is also called a buckle) provided with the length adjustment function.

The work assist suit of the present invention is configured so that the front side of the front portion and the shoulder belt are on the front body side of the best, and the back side of the back belt portion and the shoulder belt are on the back body side of the vest, respectively. The part, the back belt part, and the shoulder belt can be integrated into a vest as a whole.
When the entire assist suit is formed in a vest shape, it is preferable to connect the front and rear body parts of the left and right shoulders and the front and rear body parts of the side parts (both side parts) of the vest with a connecting adjustment band. This is to match the size of the vest to the wearer's physique.

  The work assist suit according to the present invention has a front portion provided with a load supporting portion including a substantially L-shaped section and a substantially T-shaped section by a front portion having a large vertical width, a wide back belt portion, and a shoulder belt. Since it is closely attached to the front and side surfaces from the chest to the abdomen, the waist of the operator is supported by the wide back belt part, and the weight of the luggage supported by the luggage support part is effectively transmitted to the left and right shoulder belts. It is extremely useful as an auxiliary means for reducing muscle fatigue during work such as bending and moving while holding a heavy load with both arms.
