The details of the hanger hook according to the present invention are described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a hanger hook (hook member) 10 attached to a wall 1 of a vehicle or the like. The wall 1 has a front-rear direction A, a vertical direction B, and a lateral direction C, which are orthogonal to each other. Wall 1 has a thickness t defined by a front surface 2 and a rear surface 3 . The hanger hook 10 has a first hook 11 and a second hook 12 for separately hanging articles (not shown). The hanger hook 10 also has a case member 13 to which the first and second hooks 11 and 12 are attached, and a clamping member 14 that cooperates with the case member 13 to clamp the wall 1 .

FIG. 2 is a perspective view of the hanger hook 10 in FIG. 1, but illustration of the wall 1 is omitted. In the hanger hook 10, the first hook 11 is housed in the upper portion of the case member 13, but is swiveled forward in the front-rear direction A as indicated by the arrow F by being operated with a fingertip to lift the article. Functions as a hanger that can be hung. The first hook 11 is urged to turn in the direction opposite to the arrow F, in other words, in the direction to be accommodated in the case member 13. It is possible to automatically return to the state of 1 hook 11 . In FIG. 2, the second hook 12 is also housed in the lower portion of the case member 13, and when the first hook 11 is swiveled forward or operated with a fingertip, the second hook 12 can be opened as indicated by an arrow G. It advances obliquely downward toward the front and functions as a hanger capable of hanging articles. The second hook 12 is urged to move in the direction opposite to the arrow G, that is, in the direction to be housed in the case member 13. It is possible to automatically return to the 12 states. The outer peripheral edge of the case member 13 in FIG. 2 is a flange portion 16 (see FIG. 1) that contacts the front surface 2 of the wall 1 in FIG. has a clearance CL. In FIG. 1, the clearance CL is substantially the same as the thickness t of the wall 1 so that the rear surface 19 of the flange portion 16 and the front surface 18 of the clamp member 14 press against the wall 1, i.e. clamp the wall 1. By doing so, the hanger hook 10 is attached to the wall 1 (see later FIG. 3).

FIG. 3 is a side view of the hanger hook 10 in FIG. 1, and the section of the portion of the wall 1 where the hanger hook 10 is fitted is shown in phantom lines. 3, the flange portion 16 of the case member 13 is pressed against the front surface 2 of the wall 1, and the clamp member 14 is pressed against the rear surface 3 of the wall 1. As shown in FIG. This state between the flange portion 16 and the clamp member 14 relative to the wall 1 is maintained by screwing a male screw 17 extending rearward of the case member 13 in FIG. The wall 1 is formed with a mounting hole 5 (see FIG. 10) through which the portion of the case member 13 located behind the flange portion 16 and the clamp member 14 can pass from the front to the rear. It is The first hook 11 housed in the case member 13 extends upward beyond the flange portion 16 in the up-down direction B of the case member 13, and the upper end portion 11a faces the front surface 2 of the wall 1 so that it can be easily operated with a fingertip. It is pointed in a manner spaced apart from. The second hook 12 housed in the case member 13 also has a pointed front end portion 12a away from the front surface 2 of the wall 1 so that it can be easily operated with a fingertip.

4, 5 and 6 are similar to FIG. 3 showing the procedure for removing the hanger hook 10 from the wall 1. FIG. However, in FIG. 4, a portion of the clamping member 14 is broken so that the presence of the coil spring 15 and the male screw 17 can be clearly shown.

4, the male screw 17 is inserted through a through hole 21 formed in the case member 13 and extending in the front-rear direction A, and the tip portion 22 is screwed into a screw hole 23 of the clamp member 14. As shown in FIG. With the first hook 11 pivoted forward as shown in FIG. 4, the screwdriver 24 is used to rotate the external thread 17 in the counterclockwise direction W so that the clamping member 14 leaves the rear surface 3 of the wall 1. so as to create a separation distance H between the front face 18 of the clamping member 14 and the rear face 3 of the wall 1 . The upper surface 26 of the upper end portion 11a of the first hook 11 that is swiveled toward the front of the wall 1 forms a groove 27 extending in the front-rear direction A. As shown in FIG. The groove 27 is also parallel to the center line J of the male screw 17 extending in the front-rear direction A. As shown in FIG. Therefore, when the shaft portion 24a of the screwdriver 24 having an appropriate size for the male screw 17 is placed along the groove 27, the tip of the screwdriver 24 substantially coincides with the center of the male screw 17 and is formed on the head portion 17a of the male screw 17. It fits easily into a cross groove (not shown). With the hanger hook 10 in which the screwdriver 24 can be so set, tightening and loosening the external thread 17 becomes easier and faster.

Hanger hook 10 in the state shown in FIG. When the case member 13 is slightly moved forward so as to protrude outward, as shown in FIG. The portion 31 is positioned in the mounting hole 5 .

4 and 5, when the support frame 31 is positioned in the mounting hole 5, the case member 13 is separated from the upper end portion 31a of the support frame 31 by a distance K in the vertical direction B. When the hanger hook 10 is lifted to the point where the upper end portion 31a contacts the upper end portion 5a between the upper end portion 5a of the mounting hole 5, the lower end portion 31b of the support frame portion 31 and the lower end portion 14b of the clamp member 14 are mounted. Positioned above the lower end portion 5b of the hole 5, a separation distance k smaller than the distance K is created between the lower end portion 14b of the clamp member 14 and the lower end portion 14b. Therefore, as shown in FIG. 6, when the entire hanger hook 10 is turned clockwise D so that the lower end portion 14b of the clamp member 14 turns clockwise D, the lower end portion 31b of the support frame portion 31 is turned. and the lower end portion 14b of the clamp member 14 come out of the mounting hole 5. As shown in FIG. Next, as shown in FIG. 7, when the entire hanger hook 10 is moved obliquely downward as indicated by an arrow E, the hanger hook 10 is pulled out of the mounting hole 5, and the hanger hook 10 is removed from the wall 1. can be removed.

When attaching the hanger hook 10 to the wall 1, the order of the operations shown in FIGS. 3 to 7 may be reversed. However, in the mounting operation, the upper end portion 14a of the clamp member 14 is inserted into the mounting hole 5 from the direction opposite to the direction indicated by the arrow E in FIG. 7, and the direction opposite to the direction indicated by the arrow D in FIG. The fitting guide portion 29 of the hanger hook 10 is fitted into the mounting hole 5 while the hanger hook 10 is rotated. Then, when the hanger hook 10 is released, the upper end portion 16a of the flange portion 16 of the hanger hook 10 is located above the upper end portion 5a of the mounting hole 5 in front of the wall 1, that is, on the outer side (see FIGS. 4 and 5). , the lower end portion 16 b of the flange portion 16 is located below the lower end portion 5 b of the mounting hole 5 . Further, behind the wall 1, that is, inside, the upper end portion 14a of the clamp member 14 (see FIGS. 6 and 7) is positioned above the upper end portion 5a of the mounting hole 5, and the lower end portion 14b of the clamp member 14 is located above the mounting hole 5. It is below the lower end portion 5b (see FIG. 4). A lower end portion 29 b of the fitting guide portion 29 is in contact with the lower end portion 5 b of the mounting hole 5 . Therefore, the hanger hook 10 is temporarily fixed to the mounting hole 5 so as not to come out of the mounting hole 5 either forwardly or rearwardly.

When the hanger hook 10 in such a state is rotated in the tightening direction by supporting the fitting guide portion 29 in the mounting hole 5 and rotating the male screw 17, the clamping member 14 is held. Approaching the rear face 3 of the wall 1, the wall 1 can be clamped at the periphery of the mounting hole 5 in cooperation with the flange portion 16 so that the hanger hook 10 can be mounted on the wall 1.

When a large number of hanger hooks 10 that can be handled in this way are to be attached to the wall 1, one worker sequentially attaches the large number of hanger hooks 10 to the attachment holes 5 in a temporarily fixed state, Another worker can hold the screwdriver 24 and concentrate on tightening the male screw 17 . In such a way of working, the operator has to press the hanger hook against the wall with one hand to keep the hook pivoted forward, while the other hand is used to operate the screwdriver. You can install many hanger hooks on the wall in a short time.

FIG. 8 is a rear perspective view of the hanger hook 10 in which the case member 13 and the clamp member 14 are separated and the entire second side wall 42 of the case member 13 is visible. The case member 13 includes a flange portion 16, a fitting guide portion 29, and a support frame portion 31, as well as a first hook 11, a second hook 12, and a ring cam 50. FIG. A perspective view of ring cam 50 is also added.

In the case member 13 , the dimensions in the vertical direction B and the horizontal direction C of the flange portion 16 are larger than the dimensions in the vertical direction B and the horizontal direction C of the mounting hole 5 of the wall 1 . The fitting guide portion 29 has a shape and size that fits into the mounting hole 5, and the thickness P of the fitting guide portion 29 is substantially equal to the thickness t of the wall 1 (see FIG. 1). A preferable fitting guide portion 29 has a shape, a size and a thickness P that make sliding contact with the peripheral wall of the mounting hole 5 . The support frame portion 31 extends rearward from the fitting guide portion 29, and has an upper end portion 31a forming an upwardly convex arc and a lower end forming a downwardly convex arc. It has a portion 31b and a first side wall 41 and a second side wall 42 extending between the upper end portion 31a and the lower end portion 31b and opposed in the lateral direction C. As shown in FIG. A through hole 21 for inserting the male screw 17 extends in the front-rear direction A in the upper end portion 31a. Through holes 41a and 41c (refer to FIG. 10) and through holes 42a, 42b, 42c and 42d (see FIG. 10) and through holes 42a, 42b, 42c and 42d (above) are formed in the first side wall 41 and the second side wall 42 to support a plurality of pin members which will be described later. 8) are formed. The first side wall 41 and the second side wall 42 are formed with oval guide holes 45 and 46 into which the slide pin 43 of the second hook 12 is slidably inserted (see also FIG. 10). reference). Between the support frame portion 31 and the fitting guide portion 29, the upper end portions 31a and 29a are separated from each other by a dimension M, and the lower end portions 31b and 29b are substantially coincident with each other. The first and second side walls 41 and 42 of the support frame portion 31 are spaced apart from the side edges 29c (see FIG. 10) and 29d of the fitting guide portion 29 by a dimension N, respectively.

The ring cam 50, shown removed from the case member 13, comprises a rotating shaft 51, a second gear portion 52 concentric with the rotating shaft 51, an arm portion 54 for pressing against the second hook 12, and a first biasing spring which will be described later. and a pin portion 55 for hooking one end of 71 . The rotating shaft 51 is inserted into the through hole 42b of the second side wall 42 of the support frame portion 31. As shown in FIG. 10, the ring cam 50 is also formed with a third gear portion 53 coaxial with the rotary shaft 51. As shown in FIG.

In FIG. 8, the clamp member 14 shown behind the case member 13 has an upper end portion 14a and a lower end portion 14b that are opposed in the vertical direction B and form an arc, and in addition, are opposed in the lateral direction C and are vertically aligned. Side wall portions 14c and 14d extend straight to B, and a connecting portion 56 extends between both side wall portions 14c and 14d. A threaded hole 23 for screwing the male screw 17 is formed in the connecting portion 56 . A step 57 is formed between the front surfaces 18 of the upper end portion 14a and the lower end portion 14b and the front surfaces 14e of the side wall portions 14c and 14d. equal to or slightly greater than the thickness P.

Between the case member 13 and the clamp member 14 thus formed, the dimension R1 of the fitting guide portion 29 is equal to the inner dimension R2 of the clamp member 14 in the vertical direction B, in other words, the height direction of the hanger hook 10 . , and the outer dimension R4 of the clamping member 14 is greater than the dimension R5 of the mounting hole 5 (see FIG. 10). In the lateral direction C, in other words, the width direction of the hanger hook 10, the dimension S1 of the case member 13 is larger than the dimension S6 of the mounting hole 5 (see FIG. 10). Also, the dimension S4 of the fitting guide portion 29 is slightly smaller than the dimension S6. The dimension S5 of the support frame 31 is smaller than the dimension S4 and slightly smaller than the inner dimension S2 of the clamp member 14, so that the support frame 31 can be fitted to the clamp member 14 from the inside. . The outer dimension S3 of the clamping member 14 is smaller than the dimension S6 of the mounting hole 5 . If the dimensions R1 to R5 and the dimensions S1 to S6 are as described above and the mounting hole 5 of the wall 1 is large enough to allow the fitting guide portion 29 to be fitted, the clamp member 14 will force the mounting hole 5 into place. can pass without 3 and 4, the clamp member 14 passed through the mounting hole 5 does not slip out of the mounting hole 5 when directed in the vertical direction B so as to be parallel to the wall 1. As shown in FIGS. In addition, as illustrated in FIG. 4, even if the male screw 17 is rotated by the screwdriver 24, the clamp member 14 to which the male screw 17 is screwed can smoothly move linearly in the front-rear direction A along the support frame portion 31. It does not show any movement or rotation around the external thread 17 . The preferred clamp member 14 moves in the front-rear direction A while sliding relative to the support frame 31 .

9 and 10, FIG. 9 is a partially broken perspective view of the hanger hook 10 shown in FIG. 8, and FIG. 10 is an exploded perspective view of the hanger hook 10 viewed from the rear. However, FIG. 9 also shows a perspective view of the ring cam 50 as a single unit. Moreover, in FIG. 10, the entire first side wall 41 of the case member 13 is visible. 9 and 10, the first hook 11 that is housed in the case member 13 and extends in the vertical direction B has a lower end portion 11b between both side walls 41 and 42 of the case member 13 and passes through the lower end portion 11b. It reciprocates with a shaft 60 supported by both side walls 41 and 42 as a pivot. A first gear portion 61 and a stopper engagement portion 62 are also formed on the lower end portion 11b so as to center on the shaft 60. As shown in FIG. The second hook 12 in FIG. 9 is also housed in the case member 13 . The second hook 12 is located outside the case member 13 and has a front end portion 12a (see FIG. 10) formed so that the user's (not shown) fingertip can be acted upon. and a rear end portion 12 b located inside the case member 13 . The rear end portion 12b includes a rear end surface 63 on which the tip of the arm portion 54 of the ring cam 50 acts, and a guide pin 43 extending horizontally in both lateral directions C through the rear end portion 12b. Both ends of the guide pin 43 enter respective oval guide holes 45 and 46 formed in the support frame portion 31 of the case member 13 . The rear end portion 12b also has a smooth upper surface 65 and an arcuate lower surface 66 at a portion connected to the front end portion 12a.

As is clear from FIG. 9, a ring cam 50 is interposed between the first hook 11 and the second hook 12. As shown in FIG. Between the shaft 60, which is a pin member extending between the side walls 41 and 42 of the case member 13, and the pin portion 55 of the ring cam 50, there is a first biasing spring 71 extending under tension. By the action of 71, the ring cam 50 in FIG. In FIG. 9, arrows V and F point in the same direction. The second gear portion 52 of the ring cam 50 meshes with the first gear portion 61 (see FIG. 10) formed on the first hook 11 to move the first hook 11 about the shaft 60 in the direction opposite to the arrow F. In other words, the first hook 11 is urged in the direction in which it is housed in the case member 13 so as to turn outward. The lower end portion 54b of the arm portion 54 of the ring cam 50 approaches or contacts the rear end surface 63 of the second hook 12 .

9, between the pin member 68 fixed to the second side wall 42 of the support frame portion 31 in the case member 13 and extending toward the first side wall 41 and the guide pin 43 in the second hook 12, The second biasing spring 72 extends in a tensioned state and biases the second hook 12 in a direction to be accommodated in the case member 13, that is, to ascend obliquely rearward along the guide holes 45 and 46. . Although not shown, the second hook 12 has an upper surface 65 and a lower surface 66 (see FIG. 10) facing each other in the case member 13 with complementary shapes. By sliding on the part, it is possible to move forward and backward smoothly with respect to the case member 13 without swinging in the vertical direction B or the lateral direction C.

In the hanger hook 10 of FIG. 9 formed in this way, when the fingertip is applied to the upper end portion 11a of the first hook 11 and the first hook 11 is turned in the direction indicated by the arrow F, the first hook 11 is rotated in the direction indicated by the arrow F. The 1 gear portion 61 also rotates clockwise. On the other hand, the ring cam 50 having the second gear portion 52 meshing with the first gear portion 61 rotates in the direction opposite to the arrow V against the biasing force of the first biasing spring 71 . When the ring cam 50 rotates in this manner, the arm portion 54 of the ring cam 50 also rotates and presses the rear end surface 63 of the second hook 12 at its lower end portion 54b. As the guide pin 43 descends along the guide holes 45 and 46, the front end portion 12a of the second hook 12 whose rear end surface 63 is pressed moves obliquely downward from the case member 13, and the article can be hooked. (See Figure 2).

The first hook 11 has a stopper engaging portion 62 (see FIG. 10) at the lower end portion 11b, and the support frame portion 31 of the case member 13 has a stopper portion 64 extending in the lateral direction B between the side walls 41 and 42 (see FIG. 10). 9 and 10). The first hook 11 rotating in the direction of arrow E in FIG.

When the hand is released from the first hook 11 that has turned in the direction of arrow F, the first biasing spring 71 contracts to rotate the ring cam 50 and the second gear portion 52 in the direction of arrow V, and the first gear portion 61 rotates. Rotate in the direction opposite to arrow V. As the first gear portion 61 rotates in the direction opposite to the arrow V, the first hook 11 turns in the direction opposite to the arrow F and returns to the state shown in FIGS. Further, when the ring cam 50 rotates clockwise, the arm portion 54 of the ring cam 50 also rotates, and the lower end portion 54 b of the arm portion 54 separates from the rear end surface 63 of the second hook 12 . Then, the second hook 12 is released from the urging force in the direction of advancing from the case member 13, allowing the contraction of the second urging spring 72, and moving in the direction to be accommodated in the case member 13, that is, in the direction to retreat. Moving.

Since the hanger hook 10 is formed in this way, the second hook 12 also advances with respect to the case member 13 in conjunction with the pivotal motion of the first hook 11 advancing and retreating with respect to the case member 13 .・Retreat is possible. However, since the second hook 12 and the ring cam 50 are only such that the arm portion 54 of the ring cam 50 abuts against the rear end surface 63 of the second hook 12, the front end portion 12a of the second hook 12 is placed with the fingertip. By pulling out obliquely downward, only the second hook 12 can be used independently of the first hook 11, that is, a state in which an article can be hung can be obtained. Further, when the finger is released from the second hook 12 in such a state, the second hook 12 returns to the state shown in FIGS. .

The member 70 shown in FIG. 10 is a damper, which controls the speed at which the ring cam 50 rotates in the direction indicated by the arrow V in FIG. used to control. The damper 70 is fitted into the mounting hole 75 (see FIG. 10) in the first side wall 41 of the support frame 31, and at the same time, the rotating gear portion 77 of the damper 70 is engaged with the third gear portion 53 formed in the ring cam 50. By meshing, it is possible to support the ring cam 50 from the side of the first side wall 41 and at the same time control the rotational speed of the ring cam 50 . Such a damper 70 is well known in the art, so detailed description thereof will be omitted.

The hanger hook 10 formed in this manner is suitable for use by attaching it to the wall of a vehicle such as a train.
