実公平５−１７１６３号公報Japanese Utility Model Publication No. 5-17163

上記構成では、作業者の背中に生じた湿気が、背当部材の溝部の空気と共に溝部の複数の孔を通って背負部材の通気孔に排出され、送風機に吸引される。このため、作業者の背中の蒸れが軽減される。しかしながら、背当部材の溝部以外の部分は作業者の背中に当接し、その部分に生じた湿気は排出されない。このため、上記構成では、作業者の背中の蒸れが十分に軽減されなかった。   In the above configuration, moisture generated on the operator's back is discharged together with the air in the groove portion of the backrest member through the plurality of holes in the groove portion to the vent hole of the backpack member and sucked into the blower. For this reason, the stuffiness of a worker's back is reduced. However, portions other than the groove portion of the backrest member abut against the operator's back, and moisture generated in the portion is not discharged. For this reason, in the said structure, the stuffiness of the operator's back was not fully reduced.

本発明は、このような問題点を解決するためになされたものであり、作業者の背中の蒸れを十分に軽減することができる背負式動力作業機の提供を目的とする。   The present invention has been made to solve such problems, and an object of the present invention is to provide a backpack-type power working machine that can sufficiently reduce the stuffiness of an operator's back.

本発明による背負式動力作業機（１００）は、作業者に背負われ当該作業者の背中に面する背負部材（１）と、背負部材（１）の下端部から後方に延びた架台（３）と、架台（３）の上に搭載された送風機（６）と、背負部材（１）の作業者側に取り付けられ作業者の背中に当接する背当部材（４）と、を備えた背負式動力作業機（１００）であって、送風機（６）は、背負部材（１）との隙間の空気を吸引する吸気口（９）を有し、背負部材（１）は、作業者側から送風機（６）側に貫通した通気孔（１１）を有し、背当部材（４）は、内部の空気を背負部材（１）側に排出可能とされ、通気孔（１１）を覆うように背負部材（１）に取り付けられ、背当部材（４）の作業者側の表面は通気性のある素材で構成されていることを特徴とする。   A backpack-type power working machine (100) according to the present invention includes a backpack member (1) that is carried by a worker and faces the back of the worker, and a pedestal (3) that extends rearward from the lower end of the backpack member (1). And a fan (6) mounted on the gantry (3) and a backrest member (4) attached to the worker side of the backpack member (1) and abutting on the back of the worker. It is a power working machine (100), Comprising: A fan (6) has an inlet (9) which attracts | sucks the air of a clearance gap with a backpack member (1), and a backpack member (1) is a blower from an operator side. (6) It has a vent hole (11) penetrating on the side, and the backrest member (4) is capable of discharging the internal air to the backpack member (1) side and covers the vent hole (11). It is attached to the member (1), and the surface of the back side member (4) on the operator side is made of a material having air permeability.

このような背負式動力作業機（１００）によれば、作業者の背中に生じた湿気は、送風機（６）の吸引力により、通気性のある素材で構成された表面を通って背当部材（４）の内部に進入し、背当部材（４）の内部の空気と共に背負部材（１）の通気孔（１１）に排出され、送風機（６）に吸引される。背当部材（４）の内部の空気が排出されると、通気性のある素材で構成された表面を通して新たな空気が吸入される。そして、背当部材（４）による空気の吸入及び排出が連続的に行われ、作業者の背中に生じた湿気の吸入及び排出も連続的に行われ、その結果作業者の背中の蒸れが十分に軽減される。   According to such a backpack type power working machine (100), moisture generated on the operator's back passes through the surface made of a material having air permeability by the suction force of the blower (6), and the backrest member. It enters the inside of (4), is discharged into the vent hole (11) of the backpack member (1) together with the air inside the backrest member (4), and is sucked into the blower (6). When the air inside the backrest member (4) is discharged, new air is sucked through the surface made of a breathable material. Then, the suction and discharge of air by the back support member (4) is continuously performed, and the suction and discharge of moisture generated on the back of the worker is also continuously performed. As a result, the worker's back is sufficiently steamed. To be reduced.

ここで、上記作用を効果的に奏する構成として、背当部材（４）は、背負い時に作業者の背中と背負部材（１）とに挟まれて潰れる弾性部材（１２）と、弾性部材（１２）の作業者側を被覆する前側シート（１３）と、を有し、弾性部材（１２）及び前側シート（１３）は、通気性のある素材で構成されているものが挙げられる。   Here, as a configuration that effectively exhibits the above-described operation, the backrest member (4) includes an elastic member (12) that is sandwiched between the back of the worker and the backpack member (1) when carrying the back, and an elastic member (12 And the front side sheet (13) covering the worker side, and the elastic member (12) and the front side sheet (13) are made of a breathable material.

また、弾性部材（１２）は、ウレタンフォームで構成され、前側シート（１３）は、メッシュシートで構成されていると、弾性部材（１２）及び前側シート（１３）の通気性が確保されると共に、背当部材（４）と作業者の背中との接触面積が小さくなり、作業者の背中の蒸れがより十分に軽減される。さらに、弾性部材（１２）のクッション性が確保される。   Further, when the elastic member (12) is made of urethane foam and the front sheet (13) is made of a mesh sheet, the air permeability of the elastic member (12) and the front sheet (13) is secured. The contact area between the backrest member (4) and the worker's back is reduced, and the stuffiness of the worker's back is more sufficiently reduced. Furthermore, the cushioning property of the elastic member (12) is ensured.

また、背当部材（４）は、背負部材（１）の通気孔（１１）と対応する位置に、弾性部材（１２）が存在しない中空部（１７）を有する構成であると、中空部（１７）の通気性が向上し、背当部材（４）の内部を空気が流れ易くなる。このため、背当部材（４）の内部に進入した湿気がより早く送り出され、作業者の背中の蒸れが一層十分に軽減される。   Moreover, when the backrest member (4) is a structure which has the hollow part (17) in which the elastic member (12) does not exist in the position corresponding to the vent hole (11) of the backpack member (1), the hollow part ( The air permeability of 17) is improved, and air easily flows through the backrest member (4). For this reason, the moisture which entered the inside of the backrest member (4) is sent out earlier, and the stuffiness of the operator's back is further reduced.

また、背当部材（４）は、弾性部材（１２）の背負部材（１）側を被覆する後側シート（１５）を有し、後側シート（１５）は、前側シート（１３）よりも曲げ剛性の高い素材で構成され、背負部材（１）の通気孔（１１）と対応する位置に通気孔（１６）を有する構成であると、背当部材（４）の通気性が確保されると共に、背当部材（４）の型崩れが抑制され、背当部材（４）の管理、組付に好都合である。   The backrest member (4) has a rear sheet (15) that covers the back bearing member (1) side of the elastic member (12), and the rear sheet (15) is more than the front sheet (13). When the structure is made of a material having high bending rigidity and has a vent hole (16) at a position corresponding to the vent hole (11) of the backpack member (1), the breathability of the backrest member (4) is secured. At the same time, deformation of the backrest member (4) is suppressed, which is convenient for management and assembly of the backrest member (4).

このように本発明の背負式動力作業機によれば、作業者の背中の蒸れを十分に軽減することができる。   Thus, according to the backpack type power working machine of the present invention, it is possible to sufficiently reduce the stuffiness of the operator's back.

背当部材４は、背負い時に作業者の背中と背負部材１とに挟まれて潰れる弾性部材１２と、弾性部材１２の前側を覆う前側シート１３と、弾性部材１２の後側を覆う第１後側シート１４と、第１後側シート１４のさらに後側を覆う第２後側シート１５と、を有している。   The backrest member 4 includes an elastic member 12 that is crushed by being sandwiched between the operator's back and the backpack member 1, a front seat 13 that covers the front side of the elastic member 12, and a first rear that covers the rear side of the elastic member 12. It has the side sheet | seat 14 and the 2nd rear side sheet | seat 15 which covers the further rear side of the 1st rear side sheet | seat 14. In FIG.

弾性部材１２は、例えばウレタンフォーム等の通気性のある素材で構成されている。前側シート１３及び第１後側シート１４は、例えば布製のメッシュシート等の通気性のある素材で構成されている。第２後側シート１５は、例えば樹脂の板材など、前側シート１３よりも曲げ剛性の高い素材で構成されている。前側シート１３及び第１後側シート１４に比べ、通気性に乏しい第２後側シート１５には、図３及び図５に示すように、前後方向に貫通する通気孔１６が形成され、背当部材４の内部の空気を後側に排出することが可能となっている。また、弾性部材１２のうち、通気孔１６に対応する位置には、前後に貫通する孔が形成され、前側シート１３と第１後側シート１４との間に弾性部材１２のない中空部１７が形成されている。   The elastic member 12 is made of a breathable material such as urethane foam. The front sheet 13 and the first rear sheet 14 are made of a breathable material such as a cloth mesh sheet. The second rear sheet 15 is made of a material having higher bending rigidity than the front sheet 13, such as a resin plate. As shown in FIGS. 3 and 5, the second rear seat 15 having poor air permeability as compared with the front seat 13 and the first rear seat 14 is formed with vent holes 16 penetrating in the front-rear direction. The air inside the member 4 can be discharged to the rear side. Further, in the elastic member 12, a hole penetrating in the front-rear direction is formed at a position corresponding to the vent hole 16, and a hollow portion 17 without the elastic member 12 is provided between the front sheet 13 and the first rear sheet 14. Is formed.

このように構成された背当部材４は、背負部材１の通気孔１１を覆うように背負部材１に取り付けられている。また、背当部材４を背負部材１に取り付けた状態において、第２後側シート１５の通気孔１６及び弾性部材１２の中空部１７の位置は、通気孔１１の位置と対応し、ここでは通気孔１１の上部と対応している。   The backrest member 4 configured in this way is attached to the backpack member 1 so as to cover the vent hole 11 of the backpack member 1. Further, in the state where the backrest member 4 is attached to the backpack member 1, the positions of the vent holes 16 of the second rear seat 15 and the hollow portions 17 of the elastic member 12 correspond to the positions of the vent holes 11, and here, It corresponds to the upper part of the pores 11.

以上の背負式動力散布機１００によれば、通気性のある素材で構成された弾性部材１２の前側が、通気性のある素材で構成された前側シート１３に覆われ、背当部材４の作業者側の表面が通気性のある素材で構成されているため、作業者の背中に生じた湿気は、送風機６の吸引力により、通気性のある素材で構成された表面を通って背当部材４の内部に進入し、背当部材４の内部の空気と共に背負部材１の通気孔１１に排出され、送風機６に吸引される。背当部材４の内部の空気が排出されると、通気性のある素材で構成された表面を通して新たな空気が吸入される。そして、背当部材４による空気の吸入及び排出が連続的に行われ、作業者の背中に生じた湿気の吸入及び排出も連続的に行われ、その結果作業者の背中の蒸れが十分に軽減される。   According to the backpack type power spreader 100 described above, the front side of the elastic member 12 made of a breathable material is covered with the front seat 13 made of a breathable material, and the work of the backrest member 4 is performed. Since the surface on the worker side is made of a breathable material, the moisture generated on the operator's back passes through the surface made of the breathable material by the suction force of the blower 6, and the backrest member 4 enters into the vent hole 11 of the backpack member 1 together with the air inside the backrest member 4 and is sucked into the blower 6. When the air inside the backing member 4 is discharged, new air is sucked through the surface made of a breathable material. And, the suction and discharge of air by the back support member 4 is continuously performed, and the suction and discharge of moisture generated on the back of the worker is also continuously performed. As a result, the stuffiness of the worker's back is sufficiently reduced. Is done.

さらに、弾性部材１２は、ウレタンフォームで構成され、前側シート１３は、メッシュシートで構成されているため、弾性部材１２及び前側シート１３の通気性が確保されると共に、背当部材４と作業者の背中との接触面積が小さくなり、作業者の背中の蒸れがより十分に軽減される。さらに、弾性部材１２のクッション性が確保される。   Furthermore, since the elastic member 12 is made of urethane foam and the front sheet 13 is made of a mesh sheet, the breathability of the elastic member 12 and the front sheet 13 is ensured, and the backrest member 4 and the operator are secured. The contact area with the back of the operator is reduced, and the stuffiness of the operator's back is further reduced. Furthermore, the cushioning property of the elastic member 12 is ensured.

また、背当部材４は、背負部材１の通気孔１１と対応する位置に、弾性部材１２が存在しない中空部１７を有するため、中空部１７の通気性が向上し、背当部材４の内部を空気が流れ易くなる。これにより、背当部材４の内部に進入した湿気がより早く送り出され、作業者の背中の蒸れが一層十分に軽減される。   Further, since the backrest member 4 has the hollow portion 17 where the elastic member 12 does not exist at a position corresponding to the vent hole 11 of the backpack member 1, the air permeability of the hollow portion 17 is improved, and the interior of the backrest member 4 is improved. The air will flow easily. Thereby, the moisture which entered the inside of the backrest member 4 is sent out earlier, and the stuffiness of the operator's back is further sufficiently reduced.

また、背当部材４は、第１後側シート１４の後側、即ち弾性部材１２の後側を被覆する第２後側シート１５を有し、第２後側シート１５は、前側シート１３よりも曲げ剛性の高い素材で構成され、背負部材１の通気孔１１と対応する位置に通気孔１６を有するため、背当部材４の通気性が確保されると共に、背当部材４の型崩れが抑制され、背当部材４の管理、組付に好都合である。   The backrest member 4 includes a second rear sheet 15 that covers the rear side of the first rear sheet 14, that is, the rear side of the elastic member 12, and the second rear sheet 15 is more than the front sheet 13. Is also made of a material having high bending rigidity, and has a vent hole 16 at a position corresponding to the vent hole 11 of the backpack member 1, so that the breathability of the backrest member 4 is ensured and the backrest member 4 is deformed. It is suppressed and is convenient for management and assembly of the backrest member 4.

以上、本発明の好適な実施形態について説明したが、本発明は必ずしも上述した実施形態に限定されるものではなく、その要旨を逸脱しない範囲で様々な変更が可能である。   The preferred embodiments of the present invention have been described above. However, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

背当部材４の構成は、上記構成に限られず、内部の空気を背負部材１側に排出可能であり、作業者側の表面が通気性のある素材で構成されたものであれば他の構成であってもよい。例えば、弾性部材１２は、前側シート１３及び第１後側シート１４，１５に覆われていなくてもよい。この場合、背当部材４の作業者側の表面は、通気性のある弾性部材１２により構成される。また、弾性部材１２は、第１後側シート１４に覆われず、前側シート１３及び第２後側シート１５のみによって覆われていてもよいし、第１後側シート１４，１５に覆われず、前側シート１３のみに覆われていてもよい。   The configuration of the backrest member 4 is not limited to the above configuration, and any other configuration can be used as long as the air inside can be discharged to the backside member 1 and the surface on the operator side is made of a breathable material. It may be. For example, the elastic member 12 may not be covered with the front sheet 13 and the first rear sheets 14 and 15. In this case, the surface of the back support member 4 on the operator side is constituted by a breathable elastic member 12. Further, the elastic member 12 may not be covered with the first rear sheet 14 but may be covered only with the front sheet 13 and the second rear sheet 15 or may not be covered with the first rear sheets 14 and 15. The front sheet 13 may be covered only.

また、背当部材４の中空部１７は、通気孔１６の位置に対応して弾性部材１２に形成された孔によって構成されているが、これに限られない。例えば、図６に示すように、中空部１７は、前後から見てＵ字形状をなすように弾性部材１２に形成された切欠部により構成されていてもよい。   Moreover, although the hollow part 17 of the backrest member 4 is comprised by the hole formed in the elastic member 12 corresponding to the position of the ventilation hole 16, it is not restricted to this. For example, as shown in FIG. 6, the hollow portion 17 may be configured by a notch portion formed in the elastic member 12 so as to form a U shape when viewed from the front and rear.

また、弾性部材１２に通気性があるため、背当部材４は、中空部１７を有さないものであってもよい。   Further, since the elastic member 12 has air permeability, the backrest member 4 may not have the hollow portion 17.
