The diameters of the moving parts 57 and 69 are slightly smaller than the widths of the guide grooves 61d and 61f and the regulation grooves 61e and 61g.

  When the hook 50 approaches the rotating rod 63, the moving portion 57 moves along the guide groove 61d and the moving portion 69 moves along the guide groove 61f, and the hook gear portion 55 and the rotating rod gear portion 68 guide. The rotating rod 63 approaches the hook 50 and is positioned inside the opening portion of the hook 50 while rotating while being guided by the grooves 61d and 61f. As shown in FIG. 11, the hook abutting surface 53 and the rotating rod abutting surface 66 abut each other, and the opening portion of the hook 50 is closed. When no load is applied to the hook 50, the moving parts 57 and 69 are positioned at the upper ends of the guide grooves 61d and 61f (lower ends of the restricting grooves 61e and 61g).

  When the hook 50 is separated from the rotating rod 63, the hook gear portion 55 and the rotating rod gear portion 68 are rotated, and the rotating rod 63 is also separated from the hook 50. Therefore, as shown in FIG. Opened.

  When a load is applied to the hook 50, for example, when the hook 50 is hooked on a hook or the like, the hook gear portion 55 and the rotating rod gear portion 68 together with the pivot shafts 54 and 67 and the connecting plate 70 move upward, as shown in FIG. As shown, the moving parts 57 and 69 move from the guide grooves 61d and 61f to the regulation grooves 61e and 61g. As described above, since the restriction grooves 61e and 61g are linearly extended upward, the moving parts 57 and 69 located in the restriction grooves 61e and 61g do not move in the lateral direction (left and right direction). That is, the rotation of the hook 50 and the rotation rod 63 is restricted, and the hook 50 and the rotation rod 63 do not rotate.

  Therefore, when clothes are pinched | interposed into the pinch 1a and the hook 50 is hooked on a bag etc. and a hanging tool is suspended, the hook 50 keeps a closed state and does not remove | deviate from a bag. On the other hand, when the hook support part 60 is grasped and the lifting tool is moved upward, the moving parts 57 and 69 move relatively downward and move to the guide grooves 61d and 61f, so that the operator hooks with one hand. When 50 is brought into contact with the heel, the hook 50 and the rotating rod 63 rotate, and the operator can remove the hanging tool from the heel.

  Of the configuration of the hanger according to the fourth embodiment, the same reference numerals are given to the same configurations as those of the first to third embodiments, and detailed description thereof is omitted.

A through hole 161a is provided at the end of each of the two plates 161 (the right end in FIG. 16). Both through-holes 161a are opposed to each other. Guide protrusions 167 that are inserted into guide grooves 154 to be described later and protrude from one plate 161 toward the other plate 161 are provided above the respective through holes 161a.

  A rotating rod 163 is rotatably inserted between the two plates 161. The rotating rod 163 includes an opening / closing portion 163a that opens and closes an opening portion of the hook 150, which will be described later, and a support portion 163b that is connected to the opening / closing portion 163a and supports the hook 150.

  The opening / closing portion 163a has a ¼ arc shape, and one end portion thereof faces upward. Rotating rod grooves 164 are formed on the front and rear surfaces of the opening / closing portion 163a. A plurality of ribs 65 are juxtaposed inside the rotating rod groove 164. An end surface of one end portion of the opening / closing portion 163a is a rotating rod abutting surface 166 that abuts against a hook abutting surface 153 described later.

  A support portion 163b projects from the other end of the opening / closing portion 163a along the tangential direction of the opening / closing portion 163a having an arc shape. The support portion 163b has an elongated plate shape substantially parallel to the vertical and horizontal directions, and through holes 163c and 163d are provided in the center portion and the protruding end portion, respectively. The support portion 163 b is inserted between the two plates 161, and the central through hole 163 c is located between the two long holes 166. The diameter of the through hole 163c is smaller than the long diameter of the long hole 166. The projecting end through-hole 163d is coaxially positioned between the two through-holes 161a.

  A stepped bolt 201 (pivot) having a groove at the tip is inserted into the two through holes 161a and the through hole 163d at the protruding end. The tip of the stepped bolt 201 protrudes from the plate 161, and a C-shaped washer 201a is engaged with the groove. The diameter of the washer 201a is larger than that of the through hole 161a and is locked to the plate 161. Therefore, the stepped bolt 201 does not come out of the two through holes 161a and the through hole 163d at the protruding end. The support portion 163b, that is, the rotation rod 163 can be rotated about the stepped bolt 201 as a pivot.

  The hook 150 has a semicircular hook portion 150a arranged vertically with the opening / closing portion 163a side as an opening portion, and projects downward from a lower end portion of the hook portion 150a and is connected to a support portion 163b. With.

  A hook groove 151 is formed on each of the front surface and the rear surface of the hook portion 150a. A plurality of ribs 152 are juxtaposed inside the hook groove 151. An end surface of the upper end portion of the hook portion 150 a is a hook abutting surface 153 that abuts against the rotating rod abutting surface 166.

  The connecting part 150b includes projecting plates 155 and 155 that project downward from the front part and the rear part of the lower end part of the hook part 150a. The two protruding plates 155 face each other and are substantially parallel. An insertion groove 156 for inserting the support portion 163b is formed between the two protruding plates 155. The opening / closing part 163a side on the upper surface of the insertion groove 156 is curved so that the vertical width of the insertion groove 156 on the opening / closing part 163a side gradually increases.

  Guide grooves 154 into which the guide protrusions 167 are inserted are formed on the outer surfaces of the two protruding plates 155. The guide groove 154 extends in the vertical direction. A through hole 150c is provided below the guide groove 154 in each of the two protruding plates 155. Both through-holes 150c are opposed to each other.

  The connecting portion 150b is inserted between the two plates 161, and the support portion 163b is inserted into the insertion groove 156. The two through holes 150c of the connecting portion 150b and the through hole 163c at the center of the support portion 163b are coaxially positioned.

  A stepped bolt 202 having a groove at the tip is inserted into the two long holes 166, the two through holes 150c of the connecting portion 150b, and the through hole 163c at the center of the support portion 163b. The tip of the stepped bolt 202 protrudes from the long hole 166 of the plate 161, and a C-shaped washer 202a is engaged with the groove. The diameter of the washer 202 a is larger than the short diameter of the long hole 166. Therefore, the stepped bolt 202 does not come out of the long hole 166.

  The diameter of the stepped bolt 202 is slightly smaller than the short diameter of the long hole 166 and the diameter of the through hole 163c at the center of the support portion 163b. Therefore, the stepped bolt 202 can move up and down along the long hole 166. Further, the stepped bolt 202 can be rotated in the through hole 163c at the center of the support portion 163b.

  Next, opening and closing of the hook 150 will be described. When the hook 150 is hooked on a laundry basket or the like with the opening portion opened, a downward force is applied to the hook support 160 due to the weight of the laundry held on the pinch 1a or the support frame 1. The hook support part 160 moves downward with the guide protrusion 167 inserted in the guide groove 154 as a guide.

  At this time, the hook 150 moves relatively upward. An upward force acts on the rotating rod 163 via the stepped bolt 202. The rotating rod 163 rotates upward with the stepped bolt 201 as a fulcrum. The rotating bar 163 approaches the opening part of the hook 150, and as shown in FIG.

  Since the opening / closing portion 163a side of the upper surface of the insertion groove 156 is curved, the rotating rod 163 does not interfere with the upper surface of the insertion groove 156 when approaching the opening portion of the hook 150. Note that the entire upper surface of the insertion groove 156 may be formed in a tapered shape or a curved surface so that the opening / closing portion 163a side is on the upper side.

  When the hook 150 is hooked on a clothesline with the opening portion closed, when the operator moves the hanging tool in the left-right direction to bring the rotating rod 163 into contact with the clothespin, etc. The rotating rod 163 rotates downward, and the opening portion of the hook 150 opens. The operator can perform these operations with one hand, and the operator can easily hook the hanging tool on the hook and remove it from the hook.
