Abstract

PURPOSE: To enable the flexible distribution of loads applied to the entire shoulders and neck parts of a carrying person while matching the shape of the body of each carrying person by filling an elastic hollow body inserted below shoulder straps with gas or liquid. CONSTITUTION: A pack for an enlarging saw is provided with a plurality of shoulder straps 16, 1, a side belt 18, a pad 11, and a component assembling them together. An elastic hollow body 21 is inserted below the shoulder straps 16, 17 and filled with gas or liquid. The elastic hollow body suits the shape of the body of each carrying person and enables the flexible distribution of loads applied to the entire shoulders and neck part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a one-way O-equipment for use in supporting and transporting a saw handle during work.

The flat shoulder strap has shoulder straps 1 lateral support and padding along the hip, and the CO padding is equipped with a bell) and a hook. The shoulder struts are long and narrow to distribute the weight of the saw across the entire layer.
=hA Kudo O-shaped base, often -. However, since the backpack mainly stretches diagonally around the body, most of the load is supported by the shoulder straps that are positioned at a position IIK opposite to the support carrier with respect to the knot along the E tube. There is no way around it, so after a long support-carrying, the support-carrier feels fatigue and numbness in the shoulder where the load Kik is also exposed and tries to obtain a distribution of the O-load on both shoulders. Despite the OA pad below the shoulder wrap, it is difficult to avoid point loads that are unpleasant to the support carrier.

According to this invention, an arrangement is provided which solves the problem of asymmetric loading of the support carrier's shoulders and the discomfort caused by point loads below the support carrier's straps. This arrangement has the form of a yoke, which has a volume within it of at least /')0 air (IL body) or liquid O2 (at least 1).By means of this volume, the seal is supported *@@@1) According to body shape KIA,
Provides a flexible distribution of the load on the overall c+Jl) and neck area.

These and the additional advantages provided below are that the deployment consists of an external hollow body inserted below the shoulder strap, which elastic body is filled with gas or liquid. It is realized when it has the characteristics expressed in the feature "That".

For an example of deployment according to this invention, please refer to the drawings.
Starting from k, it will be explained below.

As mentioned above, the backpack is used to support and carry the cutting saw, and therefore has a hook for hooking the ring of the saw. The drive shaft tube of the saw, when supported by the support bearer's sentient being, rests on the pad/l along the hip. This pad has rear and front riveted joints,
This riveted joint is supported by the attached bell) /JK, and the ends of the pair of straps /4.1 are also tightened. The joint on the # side is the two belts, i.e. the left shoulder strap l? and side bell)/J〇〇〇me　O rapid I tsuk. There are two plates in the joint, 20, which can be pulled apart and have an order of 0 and 0 bel)/l,
The pull ah of /J (left shoulder strap 17, medullary belt /z) is now loosened, as shown in figure iii. Therefore, this is a safety lock that allows the support carrier to be quickly released from the backpack. 11-0 One shoulder strap should be supported from below by the shoulder of the support bearer, but the connection between the strap and the shoulder KFI
, there is a yoke/UK/Fig.) inserted into the backpack, so that the support lji on the shoulders is enlarged. The yoke is medium-sized and made of soft material. Furthermore, it has an OM-shaped interior that is shaped to accommodate the shoulders and neck area of an adult, and the 9-section is filled with overpressurized air or light liquid.

In this way, the bottom 1111 of the lift obtains a contact surface evenly against the support carrier's ]I and neck portion, and no point loads occur. The hollow IIO pressure at night can be determined individually by means of a valve through which liquid is fed into or out of the air chamber.

The possibility of using different pressures below the right and left shoulder straps is obtained by dividing the hollow into two spaces each equipped with a /':)0 valve.

A variant that allows the pressure in each layer Km to be determined individually is disclosed in the percent drop diagram. In this case, each shoulder strap has an elastic body filled with air (or liquid)3. has an independent deployment, where /') an elastic body is attached below each strap O. The medium in the elastic body O is pumped up to the desired pressure through the 9f here at the rear end of the deployment. Supplied. Unlike the stiff pads below the straps described above, with this deployment the pressure on the right and left shoulder straps can thus be determined, while point loads are eliminated.

One embodiment of the invention disclosed herein and described above is:
Of course, several zero variations can be coupled, depending on the layer and the most suitable for use.

[Brief explanation of drawings]

The iris/figure is a #1 view of the nine-cut saw saw carrying tool. Figure 1 shows a variant of the backpack and deployment. Referring to the diagram, /l is pad b / 4 * /ri is shoulder strut! , IS company side belt, Co1.・K3. Kosan shows 9 bodies in elasticity.

Claims (1)

[Claims] 1. A plurality of shoulder straps (16, 17), a side belt (
18), a pad (11), and an elastic hollow body (21, 23, 24
