図４，５，６，７に示すように、カバー部材１６の第１下側部３５が、第１受け部３１の裏面３１ｂに取り付けられ、カバー部材１６の第１上側部３７が、第２受け部３２の裏面３２ｂに取り付けられている。これにより、受け部１５（第１受け部３１及び第２受け部３２）における荷物Ｂとの接触面３１ａ，３２ａの裏面３１ｂ，３２ｂ側に、カバー部材１６が設けられた状態となっている。   As shown in FIGS. 4, 5, 6, and 7, the first lower portion 35 of the cover member 16 is attached to the back surface 31 b of the first receiving portion 31, and the first upper portion 37 of the cover member 16 is the second It is attached to the back surface 32 b of the receiving part 32. Accordingly, the cover member 16 is provided on the back surfaces 31b and 32b of the contact surfaces 31a and 32a with the load B in the receiving portion 15 (the first receiving portion 31 and the second receiving portion 32).

図７に示すように、カバー部材１６の第１下側部３５と第２下側部３６との間隔を、第１幅Ｗ１とする（カバー部材１６の第１受け部３１に対応する部分において、第１受け部３１の接触面３１ａと直交する方向でのカバー部材１６の第１幅Ｗ１）。
カバー部材１６の第１上側部３７と第２上側部３８との間隔を、第２幅Ｗ２とする（カバー部材１６の第２受け部３２に対応する部分において、第２受け部３２の接触面３２ａと直交する方向でのカバー部材１６の第２幅Ｗ２）。 As shown in FIG. 7, the distance between the first lower side portion 35 and the second lower side portion 36 of the cover member 16 is set to a first width W1 (in a portion corresponding to the first receiving portion 31 of the cover member 16). The first width W1 of the cover member 16 in the direction orthogonal to the contact surface 31a of the first receiving portion 31).
An interval between the first upper portion 37 and the second upper portion 38 of the cover member 16 is set to a second width W2 (a contact surface of the second receiving portion 32 in a portion corresponding to the second receiving portion 32 of the cover member 16). The second width W2 of the cover member 16 in the direction orthogonal to 32a).

以上の状態において、図７に示すように、カバー部材１６の第１幅Ｗ１が、カバー部材１６の第２幅Ｗ２よりも小さなものに設定されている。
この場合、第１受け部３１の厚みと、第２受け部３２の厚みとが同じであり、両方の厚みがあまり大きなものではない。これにより、第１受け部３１の厚みと、カバー部材１６の第１幅Ｗ１との合計の幅も、大きなものとはならない。 In the above state, as shown in FIG. 7, the first width W <b> 1 of the cover member 16 is set to be smaller than the second width W <b> 2 of the cover member 16.
In this case, the thickness of the 1st receiving part 31 and the thickness of the 2nd receiving part 32 are the same, and both thickness is not so big. Thereby, the total width of the thickness of the first receiving portion 31 and the first width W1 of the cover member 16 does not become large.

図４，５，６，７に示すように、支持部３４側に位置するカバー部材１６の横側部３９に、親指開口部４３が形成されており、上昇操作スイッチ２３（下降操作スイッチ２４）が、カバー部材１６の親指開口部４３に対して第１受け部３１側の部分に備えられた状態となっている。   As shown in FIGS. 4, 5, 6, and 7, a thumb opening 43 is formed in the side portion 39 of the cover member 16 located on the support portion 34 side, and the ascending operation switch 23 (the descending operation switch 24). However, it is in a state of being provided in a portion on the first receiving portion 31 side with respect to the thumb opening 43 of the cover member 16.

（作業者の手へのハンド部の装着）
作業者がハンド部２０を手で持つ場合、図４，５，６，７に示すように、作業者は手をカバー部材１６の開口部４１からカバー部材１６の空間４２に入れるのであり、カバー部材１６の第１下側部３５の内面（第１受け部３１の裏面３１ｂ側）に人差し指から小指を当て、カバー部材１６の第１上側部３７の内面（第２受け部３２の裏面３２ｂ側）に手の平を当てて、親指をカバー部材１６の親指開口部４３から外側に出す。 (Attaching the hand part to the operator's hand)
When the operator holds the hand portion 20 by hand, the operator puts his hand into the space 42 of the cover member 16 from the opening 41 of the cover member 16 as shown in FIGS. A pinky finger is applied to the inner surface of the first lower portion 35 of the member 16 (the back surface 31b side of the first receiving portion 31), and the inner surface of the first upper portion 37 of the cover member 16 (the back surface 32b side of the second receiving portion 32). ) And put the thumb out of the thumb opening 43 of the cover member 16.

作業者が手をカバー部材１６の開口部４１からカバー部材１６の空間４２に入れた状態において、作業者の手首はカバー部材１６の開口部４１から上方に出ている。接続部３３が、第２受け部３３から第１受け部３１側に少し曲がりながら上方に延びていることにより、接続部３３が作業者の手首に当たることは少ない。   In a state where the operator puts his / her hand into the space 42 of the cover member 16 from the opening 41 of the cover member 16, the wrist of the operator protrudes upward from the opening 41 of the cover member 16. Since the connecting portion 33 extends upward while slightly bending from the second receiving portion 33 toward the first receiving portion 31, the connecting portion 33 rarely hits the wrist of the operator.

これにより、カバー部材１６により作業者の手が保護された状態で、ハンド部２０が離れないように作業者の手に支持された状態となるのであり、作業者は手を動かすことによって、ハンド部２０の位置や姿勢を容易に変更することができる。   As a result, when the operator's hand is protected by the cover member 16, the hand unit 20 is supported by the operator's hand so as not to be separated, and the operator moves the hand to move the hand. The position and posture of the unit 20 can be easily changed.

作業者が手をカバー部材１６の開口部４１からカバー部材１６の空間４２に入れた状態において、カバー部材１６の親指開口部４３から親指を外側に出すことにより、親指を自由に動かすことができる。   When the operator puts his / her hand through the opening 41 of the cover member 16 into the space 42 of the cover member 16, the thumb can be freely moved by taking the thumb out of the thumb opening 43 of the cover member 16. .

カバー部材１６の親指開口部４３から親指を外側に出して、親指を自然に延ばした位置に、上昇操作スイッチ２３（下降操作スイッチ２４）が位置しており、親指による上昇操作スイッチ２３（下降操作スイッチ２４）の押し操作が容易に行える。
カバー部材１６の親指開口部４３から外側に出した親指と、カバー部材１６の空間４２の人差し指とにより、カバー部材１６の横側部３９を挟み込むようにして持つことによって、ハンド部２０から作業者の手が抜け出ようとする状態を抑えることができる。 The raising operation switch 23 (lowering operation switch 24) is located at a position where the thumb is extended outward from the thumb opening 43 of the cover member 16 and the thumb is naturally extended. The pressing operation of the switch 24) can be easily performed.
By holding the lateral side portion 39 of the cover member 16 with the thumb extending outward from the thumb opening 43 of the cover member 16 and the index finger in the space 42 of the cover member 16, It is possible to suppress the state where the hand is about to escape.

（ハンド部による荷物の保持）
例えば米袋やセメント袋等のように、粉粒体を入れた布製や紙製、ビニール製等の形状が変化し易い袋状の荷物Ｂを、ハンド部２０により保持する場合、作業者は、前述の（作業者の手へのハンド部の装着）に記載のように、右手及び左手に右及び左のハンド部２０を装着する。 (Holding luggage by hand)
For example, when holding the bag-like luggage B, such as a rice bag or a cement bag, whose shape is easily changed, such as cloth, paper, vinyl, etc., in which the granular material is put, The right and left hand parts 20 are attached to the right hand and the left hand as described in (Attaching the hand part to the operator's hand).

荷物Ｂが床に置かれている場合、第１受け部３１の先端部及びカバー部材１６の先端部４０を、荷物Ｂと床との間に入り込ませて、第１受け部３１の接触面３１ａ（滑り止め部材２８）を荷物Ｂの下側に位置させ、第２受け部３２の接触面３２ａを荷物Ｂの横側に位置させる。カバー部材１６の親指開口部４３から外側に出した親指により、荷物Ｂを動かす等の操作を行うと、前述の操作の助けとなる。   When the load B is placed on the floor, the front end portion of the first receiving portion 31 and the front end portion 40 of the cover member 16 are inserted between the load B and the floor to contact the contact surface 31a of the first receiving portion 31. The (slip prevention member 28) is positioned below the load B, and the contact surface 32a of the second receiving portion 32 is positioned on the side of the load B. When an operation such as moving the load B is performed with the thumb that is exposed to the outside from the thumb opening 43 of the cover member 16, the above-described operation is aided.

次に、後述する（アシスト器具の作業形態）に記載のように、ハンド部２０を上昇させることにより、図８に示すように、ハンド部２０により荷物Ｂを保持することができる。主に第１受け部３１により荷物Ｂの重量が支持されて、第２受け部３２により荷物Ｂを安定させることができるのであり、作業者が自身の手で実際に荷物Ｂを保持する状態に近い状態を得ることができる。   Next, as will be described later (operation form of assist device), by lifting the hand unit 20, the baggage B can be held by the hand unit 20 as shown in FIG. The weight of the load B is mainly supported by the first receiving portion 31, and the load B can be stabilized by the second receiving portion 32, so that the worker can actually hold the load B with his / her hand. A close state can be obtained.

図４及び図８に示すように、収容ケース２９が第２受け部３２の接触面３２ａから荷物Ｂ側に出ており、収容ケース２９が荷物Ｂに当たる状態となって、荷物Ｂが動き難くなり、荷物Ｂの安定した保持の助けとなる。カバー部材１６の親指開口部４３から外側に出した親指により荷物Ｂを押える等の操作を行うと、荷物Ｂの安定した保持の助けとなる。   As shown in FIGS. 4 and 8, the storage case 29 protrudes from the contact surface 32 a of the second receiving portion 32 toward the luggage B, and the storage case 29 comes into contact with the luggage B, so that the luggage B becomes difficult to move. , Helps to hold the luggage B stably. When an operation such as pressing the load B with the thumb that is exposed to the outside from the thumb opening 43 of the cover member 16 is performed, it helps to hold the load B stably.

図８に示すように、ハンド部２０により荷物Ｂを保持した状態において、第１受け部３１の接触面３１ａ（滑り止め部材２８）及び第２受け部３２の接触面３２ａを、左右両側から荷物Ｂに押圧してやればよい。
これにより、荷物Ｂが第１受け部３１の接触面３１ａ（滑り止め部材２８）、及び第２受け部３２の接触面３２ａに馴染んで、第１受け部３１の接触面３１ａ（滑り止め部材２８）、及び第２受け部３２の接触面３２ａの広い範囲に亘って荷物Ｂが接触する状態となる。 As shown in FIG. 8, in a state where the load B is held by the hand portion 20, the contact surface 31 a (slip prevention member 28) of the first receiving portion 31 and the contact surface 32 a of the second receiving portion 32 are viewed from both the left and right sides. What is necessary is just to press to B.
Thereby, the load B becomes familiar with the contact surface 31a (slip prevention member 28) of the first receiving portion 31 and the contact surface 32a of the second reception portion 32, and the contact surface 31a (slip prevention member 28) of the first receiving portion 31. ), And the load B is brought into contact over a wide range of the contact surface 32 a of the second receiving portion 32.

（アシスト器具の作業形態）
例えば、パレットや床に置かれた荷物Ｂを高い棚やトラックの荷台に置くような場合、作業者がしゃがんでパレットや床の荷物Ｂを手で持ち、次に手を下に延ばした状態で荷物Ｂを持ちながら立ち上がり、次に手で荷物Ｂを持ち上げて、荷物Ｂを高い棚やトラックの荷台に置くような状態が想定される。 (Working form of assist device)
For example, when a load B placed on a pallet or floor is placed on a high shelf or truck bed, the operator squats down and holds the load B on the pallet or floor with his hand and then extends his hand down. It is assumed that the user stands up while holding the load B, then lifts the load B by hand, and places the load B on a high shelf or truck bed.

アシスト器具を装着した作業者が前述のような作業を行う状態において、上昇操作スイッチ２３及び下降操作スイッチ２４の押し操作に基づいて、制御装置８により右及び左の脚作用部３、昇降装置１７が作動する状態について説明する。   In a state where the worker wearing the assisting device performs the above-described work, the control device 8 controls the right and left leg action units 3 and the lifting device 17 based on the pressing operation of the lifting operation switch 23 and the lowering operation switch 24. The state in which will operate will be described.

図１及び図２に示すように、作業者がアシスト器具を装着した状態において、作業者が上昇操作スイッチ２３及び下降操作スイッチ２４の両方を押し操作していないと、昇降装置１７の電動モータ２７は停止して、右及び左の脚作用部３の電動モータは停止状態（自由回転状態）となる。   As shown in FIGS. 1 and 2, the electric motor 27 of the elevating device 17 is operated unless the operator pushes both the ascending operation switch 23 and the descending operation switch 24 in a state where the operator wears the assist device. Stops, and the electric motors of the right and left leg action portions 3 are stopped (freely rotated).

作業者が歩行する場合や、作業者が膝部を曲げて腰部を落とす場合（しゃがむ場合）、作業者の太腿部に追従するように操作アーム１２が揺動するのであり、作業者の動作が妨げられることはない。   When the worker walks, or when the worker bends the knee and drops the waist (when squatting), the operation arm 12 swings so as to follow the thigh of the worker. Will not be disturbed.

次に作業者がしゃがんでパレットや床の荷物Ｂを持つ場合、作業者が下降操作スイッチ２４を押し操作すると、昇降装置１７において、電動モータ２７が繰り出し側に作動し、ワイヤ１８，１９のインナー１８ａ，１９ａが繰り出されて、ハンド部２０が下降する。下降操作スイッチ２４の押し操作を止めると、電動モータ２７が停止して、ハンド部２０が停止する。これにより、作業者は、前述の（ハンド部による荷物の保持）に記載のように、ハンド部２０により荷物Ｂを保持する。   Next, when the worker squats down and holds the pallet or the floor load B, when the worker pushes the lowering operation switch 24, the electric motor 27 is operated to the feeding side in the lifting device 17, and the inner wires 18 and 19 18a and 19a are fed out and the hand part 20 descends. When the pressing operation of the lowering operation switch 24 is stopped, the electric motor 27 is stopped and the hand unit 20 is stopped. As a result, the worker holds the load B by the hand portion 20 as described above (holding the load by the hand portion).

前述のように、電動モータ２７に電磁ブレーキ（図示せず）が備えられており、電動モータ２７の停止時及び非通電時に、電磁ブレーキは自動的に制動状態となる。
これにより、電動モータ２７が停止した状態において、昇降装置１７からワイヤ１８，１９のインナー１８ａ，１９ａが繰り出されることはなく、後述するようにハンド部２０に荷物Ｂの重量が掛かっても、ハンド部２０が下降することはない。 As described above, the electric motor 27 is provided with an electromagnetic brake (not shown), and the electromagnetic brake automatically enters a braking state when the electric motor 27 is stopped or not energized.
Thus, in a state where the electric motor 27 is stopped, the inner portions 18a and 19a of the wires 18 and 19 are not drawn out from the lifting device 17, and even if the weight of the load B is applied to the hand portion 20 as will be described later, The part 20 does not descend.

次に作業者は、ハンド部２０により荷物Ｂを保持した状態で、立ち上がることによって荷物Ｂを持ち上げる。この状態において、作業者が上昇操作スイッチ２３を押し操作すると、脚作用部３において、操作アーム１２が下側に駆動され、作業者の太腿部が下側に操作されて、作業者の立ち上がりが補助される。このように、作業者が立ち上がる際において、前述の電動モータ２７のブレーキ機能により、ハンド部２０が下降することはない。   Next, the worker lifts the luggage B by standing up while holding the luggage B by the hand unit 20. In this state, when the operator pushes the lifting operation switch 23, the operating arm 12 is driven downward in the leg action unit 3, and the operator's thigh is operated downward, so that the operator can stand up. Is assisted. Thus, when the worker stands up, the hand unit 20 does not descend due to the brake function of the electric motor 27 described above.

前述のように、作業者が上昇操作スイッチ２３を押し操作した状態で立ち上がった後、脚作用部３において、操作アーム１２が略真下に向く位置に達したことが検出されると、作業者が完全に立ち上がったと判断されて、脚作用部３の電動モータは停止状態（自由回転状態）となる。   As described above, after the operator has stood up in a state where the operator presses the ascending operation switch 23, when the leg action unit 3 detects that the operation arm 12 has reached a position that is substantially directly downward, the operator It is determined that the electric motor of the leg action unit 3 has been completely started up, and is in a stopped state (a free rotation state).

次に昇降装置１７において、電動モータ２７が巻き取り側に作動し、ワイヤ１８，１９のインナー１８ａ，１９ａが巻き取られて、ハンド部２０が上昇する。所望の位置までハンド部２０が上昇すると、上昇操作スイッチ２３の押し操作を止めることにより、電動モータ２７が停止してハンド部２０が停止する。   Next, in the lifting / lowering device 17, the electric motor 27 operates to the winding side, the inner portions 18a, 19a of the wires 18, 19 are wound, and the hand portion 20 is raised. When the hand unit 20 rises to a desired position, the push operation of the raising operation switch 23 is stopped, whereby the electric motor 27 is stopped and the hand unit 20 is stopped.

次に作業者は、荷物Ｂを置くべき高い棚やトラックの荷台等へ歩いて移動する。作業者が高い棚やトラックの荷台等に到着して、作業者が下降操作スイッチ２４を押し操作すると、昇降装置１７において、電動モータ２７が繰り出し側に作動し、ワイヤ１８，１９のインナー１８ａ，１９ａが繰り出されて、ハンド部２０が下降する。   Next, the worker walks to a high shelf on which the luggage B is to be placed, a truck bed, or the like. When the worker arrives at a high shelf, a truck bed, etc., and the operator pushes the lowering operation switch 24, the electric motor 27 is actuated to the feeding side in the elevating device 17, and the inner wires 18a, 19a, 19a is extended and the hand part 20 descends.

これにより作業者は、荷物Ｂを高い棚やトラックの荷台等に置いて、ハンド部２０を荷物Ｂから離す。このようにして、荷物Ｂを高い棚やトラックの荷台等に置くと、最初の状態に戻るのであり、次の荷物Ｂに対して同様な操作を行う。   As a result, the operator places the load B on a high shelf, a truck bed, etc., and separates the hand unit 20 from the load B. In this manner, when the luggage B is placed on a high shelf, a truck bed, or the like, the initial state is restored, and the same operation is performed on the next luggage B.
