Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a backpack frame device for a backpack type working machine, and more particularly to a backpack frame device in which a backpack band can be easily attached and detached.

[Prior art]

Known examples of backpack-type working machines include a power sprayer and a brush cutter that carries only an engine, which is a power source, on a backpack frame. For example, in a backpack type brush cutter, an endless frame is formed of a pipe material or the like, and the frame is formed into an L shape in a side view and is provided between the top end and both side portions near the bent portion. The backpack frame device is configured by locking the backpack bands, the engine is mounted on a horizontal mounting portion, and the backrest pad is mounted on the vertical portion. Further, a mounting metal fitting for mounting the lower end portion of the backpack band is fixed to the frame in a state of protruding in the width direction.

[Problems to be solved by the device]

In the backpack frame device as described above, the frame itself can be housed in a certain shape, but since only the mounting bracket for mounting the lower end portion of the backpack band has a shape that is projected in the width direction, It is necessary to increase the maximum value of the packaging container by the amount of the overhanging mounting hardware. In addition, after packing once, a gap is formed between the frame and the container in the portion excluding the fittings, and the packed load moves inside the container, so it is necessary to close the gap with a filler. Furthermore, in the case of a backpack-type working machine, first pass one of the left and right arms into one backpack band, and from the state where it is written on one shoulder, next to the inside of the remaining backpack band whose lower end is locked. It was very cramped to carry on my back because I put it on my back by passing my arm through. Therefore, this device is designed so that the hooks at the lower end of the backpack band are free so that the mounting metal fittings that extend in the width direction of the backpack do not interfere with the packing process and that the work of carrying on the back is easy, and it is easy to carry it after carrying the backpack. It is intended to be installed.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention has a backpack frame.
Lower bracket 14 that integrates 10 with the pad 12 on the back
And a hook ring whose end is pivotally attached to the partial cylindrical portion 14V of the lower bracket 14 to lock the hook 21 of the backpack band.
15 and the hook ring 15 includes a lower bracket 14
, The spring edge 14Y of the locking plate 14X and the locking groove 14Z
The hook link 15 and the spring edge 14Y and the locking edge 14Z side away from each other.
When the hook 21 of the backpack band is inserted into this, it is characterized in that it has a larger through hole 15X. Further, a reinforcing member 17 is provided diagonally at the bent portion of the backpack frame 10, and the reinforcing member 17 is configured to have a vertically elongated through hole 17X when inserting the hook 21 of the backpack band. It is characterized by.

[Action]

With the above configuration, the backpack frame device for a backpack shoulder working machine of the present invention has the hook ring 15 with respect to the lower bracket 14,
The locking plate 14X is rotatable between a position projecting toward the spring edge 14Y and the locking edge 14Z side and a position away from the spring edge 14Y and the locking edge 14Z, and the reinforcing member 17 has a vertically long through hole. Formed 17X, so it does not get in the way of packing. Also, attach the hook ring 15 to the locking plate 14X of the lower bracket 14.
The hook 21 of the backpack band can be easily attached to the position projecting to the spring edge 14Y and the locking edge 14Z side or to the through hole 17X of the reinforcing material 17.

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7. In these figures, reference numeral 10 indicates a backpack frame formed by molding a pipe material or the like into an endless type, and has a mounting portion 10X on which an engine is mounted and a backpack portion 10Y standing upright at a substantially right angle. An engine mounting base 11 is attached to the mounting portion 10X, and a backpack pad 12 in which a cushion material 12B is fixed to a plate 12A is attached to the backpack portion 10Y. The upper end of the backing pad 12 has a hook 13A whose one end is locked to the pipe material of the backpack frame 10, and the other end has an upper bracket 13 having a flap 13B capable of making surface contact with the plate 12A. It can be attached by screwing the bolt 13X. The lower end of the backpack pad 12 is fixed to the backpack frame 10 by a lower bracket 14 different from the bracket 13. The lower bracket 14 includes a flap 14A that can be in close contact with the plate 12A and a hook portion 1 that makes a half turn around the pipe of the backpack frame 10.
It has a 4B, and a pad 1
The locking plate 14X extends over the entire width of 2, and this locking plate
A spring edge 14Y is formed on the upper edge of 14X so that a hook ring 15 described later can be locked and accommodated, and the edge of the locking plate 14X corresponds to the size of the hook ring 15. A locking edge 14Z is formed. Further, the hook portion 14B has a substantially semicircular shape capable of accommodating the pipe material of the backpack frame 10, and a small partial cylindrical portion 14V accommodating the end portion of the hook ring 15 is formed adjacent to the semicircular portion. There is. The flap 14A and the locking plate 14X are provided with screw holes 14H which are screwed to the plate body 12A and fixed with screws 16. The hook ring 15 is an L-shaped ring as a whole with an insertion end 15A at the end of a wire rod, and has a through hole 15X having a large size in the vertical direction as a locking hole. A reinforcing member 17 is obliquely provided in a cross-shaped form at the bent portion between the placing portion 10X of the backpack frame 10 and the backpack portion 10Y, and the upper end of the backpack band 20 is provided at the top end of the backpack frame 10. A fitting 18 for locking is fixed. Further, as shown in FIG. 7, the reinforcing member 17 may be made to have a width dimension, and a long and narrow window hole 17X may be formed in the longitudinal direction so that the hook 21 at the lower end of the backpack band 20 can be easily hooked. it can. The hook link 15 has its insertion end 15A inserted into the partial cylindrical portion 14V of the lower bracket 14 and attached so as to be rotatable about the insertion end 15A. Therefore, the hook ring 15 extends in the width direction centering on the partial cylindrical portion 14V, holds it between the spring edges 14Y of the locking plate 14X, and positions the through hole 15X on the back of the pad 12 on the back. As a result, the hook 21 of the backpack band 20 is replaced by the dimension 1 of the hook 21
Insert hook 21 into through hole 15X with larger size L
Lock to the top edge of 5X. This operation can be easily performed even if the operator extends his / her hand to the rear and gropes. Further, facilitation of the work of locking the backpack band 20 can also be realized by the second embodiment (Fig. 7). Further, when the backpack frame is packed in the container, the hook ring 15 is rotated about the insertion end 15A and folded inward to eliminate the overhang state.

[Effect of device]

As is clear from the above description, according to the backpack frame device for a backpack type working machine of the present invention, the end of the hook ring 15 can be freely rotated with respect to the lower bracket 14 attached to the backpack frame 10. The hook ring 15 can be attached to the lower bracket 14 in the extended state by using the spring edge 14Y, and the hook ring 15 can be provided with a through hole 15X larger than the hook 21 of the backpack band or the backpack. Frame 1
Since the vertically elongated through hole 17X is formed in the reinforcing material 17 that is diagonally provided at the bent portion of 0, the hook ring 15 or the reinforcing material 17 is used at the time of packing.
Does not get in the way, and has an effect that the hook 21 of the backpack band can be easily locked in the through hole 15X or the through hole 17X when carrying a backpack.
