The click stop member 4 is formed by press-fitting from the opened square hole 142.

  At this time, since the outward flanges 46 of the projections 45 provided in the opening of the push button 44 have roundness, when the four projections 45 are inserted into the square holes 142, the inside of the square holes 142 The projection 45 can be restored to the outside and the push button 44 cannot be pulled out by the flange 46 after passing through.

  The connecting portion 25 of the engaging member 2 and the arm 32 of the rotating member 3 are connected in advance by a link 26.

  When the engaging member 2 is pushed between the parallel parallel wall surfaces 101 and 103 of the housing 1, the hook portions 102 and 104 formed inside the opposing wall surfaces 101 and 103 by the side surfaces of the engaging member 2. Since the tapered surface is expanded and elastically deformed, the engaging member 2 can be fitted between the parallel parallel wall surfaces 101 and 103 of the housing 1.

  Thus, when the engaging member 2 is fitted between the opposing parallel wall surfaces 101 and 103 of the housing 1, the lower surface of the engaging member 2 slides on the bottom surface of the housing 1, and the engaging member 2. Since the upper surface of the housing 1 can slide along the lower surfaces of the hook portions 102 and 104 of the housing 1, the engaging member 2 slides between the parallel parallel wall surfaces 101 and 103 of the housing 1 in the lateral direction. can do.

  Next, the operation assembly B attached to the outside of the body part of the heel will be described.

  As shown in the assembly diagram of FIG. 8, the operation assembly B includes an elongated substrate 6 (see FIG. 9) having semicircular ends at both ends, a handle 7 (see FIG. 10) that is manually rotated, and the handle 7 as a substrate. 6 and a lid member 9 (see FIG. 11) fixed inside the handle 7 for covering the pivot member 8. 12).

  As shown in a front view (a), a plan view (b), a bottom view (c), and a side view (d) of FIG. 9, the substrate 6 has a pivot shaft 81 of the pivot member 8 at a position off the center. A cylinder 61 is formed in which a through hole 61 is inserted and a second protrusion 17 having a through hole of the engagement assembly A and a third protrusion 16 having a rectangular column shape having a through hole are brought into contact with each other by a tapping screw. The projections 63 and 64 are integrally formed.

  On the front side of the substrate 6, a cylindrical ridge 62 is formed surrounding the entire circumference of the hole 61. The cylindrical ridge 62 has a stepped portion so that the half circumference 621 is high and the other half circumference 622 is low. Is formed. Further, a notch 65 is formed in the semicircular end face far from the hole 61 of the substrate 6.

  The handle 7 has substantially the same planar shape as that of the substrate 6, and is a front view (a), a plan view (b), a bottom view (c), a side view (d) and a longitudinal section in FIG. As shown in FIG. (E), it has an arcuate top surface 71 in a cross-sectional shape orthogonal to the longitudinal direction, and inside this top surface 71, two ridges 72 arranged in parallel, One protruding stopper 73 and three protrusions 74 for caulking the lid member 9 (see FIG. 12) are formed. Further, a projection 75 that engages with the notch 65 of the substrate 6 is formed on one end face.

  The rotating member 8 is fitted inside the handle 7, and is a front view (a), a plan view (b), a bottom view (c), a side view (d), and a plan view (b) in FIG. As shown in the cross-sectional view (e) cut by ee and the cross-sectional view (f) cut by the line ff in the plan view (b), the plate portion 82 and the rotary shaft 81 are configured. 82 has a semicircular end and an elongated protrusion 821 formed at the other end, and the rotation shaft 81 protrudes from the center of the semicircular portion at one end of the plate portion 82. Further, a rectangular long hole 822 into which the coil spring 85 is fitted is formed in the plate portion 82 between the protruding portion 821 and the base portion of the rotating shaft 81.

  The rotation shaft 81 is inserted into the oval hole 35 of the rotation member 3 of the engagement assembly A. As shown in the bottom view (c) of FIG. It is an oval shape having two arc surfaces opposed to a plane. Further, a groove 811 for fitting the C-shaped retaining ring 86 is formed around the entire base of the rotating shaft 81.

  As shown in FIG. 11, a circular groove 83 is formed over the entire circumference of the base of the rotating shaft 81, and this groove 83 is a cylindrical shape formed around the hole 61 of the substrate 6. It engages with the ridge 62, and the stepped portion is such that the groove 84 is shallow on one quarter of the circle (90 degrees), and the groove 85 is deep on the other three quarters (270 degrees). Is formed. Due to the step portion of the groove 83 and the step portion of the cylindrical protrusion 62 of the substrate 6, the rotation shaft 81 of the rotation member 8 is perpendicular to the substrate 6 in the longitudinal direction and the longitudinal direction. The rotation angle is limited so that it can be rotated by an angle range of 90 degrees.

  The lid member 9 covers the rotating member 8 and the coil spring 85 fitted inside the handle 7 as shown in the front view (a), plan view (b), and bottom view (c) of FIG. Thus, an elongated hole 91 that allows movement of the rotation shaft 81 of the rotation member 8 and three holes 92 that are fitted into the three protrusions 74 of the handle 7 to be caulked are formed.

  Next, the process of assembling the operation assembly B by combining the parts described above will be described with reference to the assembly diagram of FIG.

  First, on the inside of the handle 7, the protrusion 821 of the rotating member 8 is aligned between the two protrusions 72 of the handle 7, and the rectangular long hole 822 of the rotating member 8 is fitted into the stopper 73 of the handle 7, The coil spring 85 is compressed and fitted between one end of the long hole 822 and the stopper 73, and the shaft 81 is attracted to the center by its elasticity. In other words, the protrusion 75 of the handle 7 is notched in the notch of the substrate 6. Acts to engage with 65.

  Then, the lid member 9 is fitted inside the handle 7 so that the pivot shaft 81 of the pivot member 8 protrudes from the elongated hole 91 of the lid member 9, and the three holes 92 of the lid member 9 are inserted into the three holes 92 of the lid member 9. The lid member 9 is fixed to the handle 7 by inserting the projection 74 and caulking the tip of the projection 74.

  While inserting the pivot shaft 81 of the handle 7 incorporated in this way into the hole 61 of the substrate 6, the handle 7 is superimposed on the substrate 6, and a washer 87 is fitted on the pivot shaft 81 protruding to the back side of the substrate 6, When the C-shaped retaining ring 86 is fitted into the groove 811 formed at the base of the rotation shaft 81 from the side, the handle 7 is coupled to the base plate 6 so as to be rotatable within an angle range of 90 degrees, and the operation assembly is performed. The assembly of B is completed.

  When attaching the engagement assembly A and the operation assembly B to the body part of the heel, three holes through which the rotating shaft 81 and the cylindrical protrusions 63 and 64 projecting from the operation assembly B can be inserted in the body part of the heel I can make it.

  From the front side of the body part of the heel, the rotation shaft 81 of the operation assembly B and the cylindrical protrusions 63 and 64 are inserted into the three holes already drilled, and the engagement assembly A is brought into contact with the back side of the body part of the heel. Then, the rotation shaft 81 protruding from the operation assembly B is inserted into the oval hole 35 of the rotation shaft 31 of the engagement assembly A, and the second protrusion 17 and the square columnar third protrusion 16 of the engagement assembly A are inserted. Are respectively brought into contact with the cylindrical protrusions 63 and 64 of the operation assembly B, and a tapping screw is inserted into each of the through holes of the second protrusion 17 and the prismatic third protrusion 16 of the engagement assembly A, The engagement assembly A and the operation assembly B are combined by screwing into the cylindrical protrusions 63 and 64 of the assembly B.

  Next, an operation method of locking / unlocking / locking in the locking device of the present invention configured as described above will be described with reference to FIG.

  When the handle 7 of the operation assembly B is displaced in the longitudinal direction against the elastic force of the coil spring 85, the engagement of the projection 75 of the handle 7 and the notch 65 of the substrate 6 is disengaged, and the handle 7 is turned. 8 and the rotation shaft 81 rotate, and the rotation shaft 31 of the rotation member 3 of the combined engagement assembly A also rotates. By the rotation of the rotation shaft 31, the engaging member 2 connected by the link 26 slides in the horizontal direction between the parallel wall surfaces 101 and 103 of the housing.

  If the lid of the bag is opened and no turning force is applied to the handle 7, the end faces of the protrusions 23 and 24 of the engaging member 2 enter the slits 121 and 131 of the compartments 12 and 13 of the housing 1 and face each other. The neutral state shown in FIG. 13A is maintained by staying in front of the coil springs 122 and 132.

  In this neutral state, the taper surface 21 having an acute angle α of the engagement piece 20 of the engagement member 2 protrudes under the long hole 11 formed in the top surface of the housing 1 and interlocks with the engagement member 2. The handle 7 has an acute angle of about 70 degrees with respect to the substrate 6.

  In this state, when the lid of the bag is closed and the locking hook C is inserted into the elongated hole 11 of the engagement assembly A, as shown in FIG. The taper surface 21c slides on the upper taper surface 21 of the engagement piece 20, and moves the engagement member 2 in the lateral direction (left direction in the figure) together with the engagement piece 20 against the elasticity of the coil spring 122. . After this movement, due to the elasticity of the restored coil spring 122, the upper taper surface 22c of the locking hook C engages with the lower taper surface 22 of the engagement piece 20 of the engagement member 2, The vicinity of both tip portions of the joining piece 20 and the engaging piece 20c are engaged with each other.

  Thus, when the vicinity of the front-end | tip part of the engagement piece 20 and the engagement piece 20c engages, the lid | cover of a heel will be in the temporarily fastened state, and a clearance gap will remain between a cover part and a body part. .

  Next, when the handle 7 is rotated until it overlaps the substrate 6, that is, until it is parallel to the opening of the body part, as shown in FIG. 13C, the rotation shaft 31 of the rotation member 3 rotates. The engaging member 2 moved and connected by the link 26 moves in the lateral direction (right direction in the figure).

  In this movement, the protrusion 24 of the engaging member 2 enters the slit 131 of the partition 103 of the housing 1 and moves while resisting the elasticity of the coil spring 132.

  During this movement, the lower tapered surface 22 of the engagement piece 20 of the engagement member 2 slides on the upper tapered surface 22c of the engagement hook C, so that the engagement hook C of the lid portion is held. Since it is attracted to the part side, there is no gap between the lid part and the body part, and it can be completely closed.

  When the handle 7 is rotated until it overlaps the substrate 6, the protrusion 75 of the handle 7 starts to slide on the arc surface at the end of the substrate 6. The handle 7 can be moved in the longitudinal direction with respect to the rotation shaft 81 of the rotating member 8 by the rotating member 8 and the coil spring 85 fitted inside the handle 7. Then, it slides on the arc surface of the end portion of the substrate 6 against the elasticity of the coil spring 85, and fits into the notch 65 of the substrate 6 to be locked.

  In this state where the handle 7 is locked, the link 26 connected between the arm 32 of the rotating member 3 and the engaging member 2 is stopped beyond a straight dead center, so that the coil The engaging member 2 is not pushed back together with the protrusion 24 by the elasticity of the spring 132, and the engagement with the locking hook C is released and the hook is not opened carelessly.

  Further, in the case of locking so that the heel is not opened, if the key (not shown) is operated to push the locking member 36 toward the rotating shaft 31 of the rotating member 3, the tip of the locking member 36 Since the engaging projection 37 formed on the engaging portion engages with the locking piece 33 of the rotating shaft 31 to prevent the rotating shaft 31 from rotating, the handle 7 interlocked with the rotating shaft 31 cannot be turned. The lock can be locked.

  When unlocking the hook, operating a key (not shown) to release the locking member 36 from the rotating shaft 31 of the rotating member 3 causes the engaging protrusion 37 at the tip of the locking member 36 to rotate. Since the rotary shaft 31 is rotatable away from the locking piece 33 of the moving shaft 31, the handle 7 interlocked with the rotary shaft 31 can be turned and the bag can be unlocked.

  When the handle 7 is rotated 90 degrees, the engagement between the engagement piece 20c of the locking hook C and the engagement piece 20 of the engagement member 2 is completely released as shown in FIG. 13 (d). At this time, the wedge-shaped protrusion 41 of the click stop member 4 is engaged with the groove 30 formed on the outer periphery of the rotation shaft 31 of the rotation member 3.

  When the lid is closed, the click stop member 4 is pressed by the push member D by the gravity of the lid and the coil spring 47 is strongly compressed. 41 strongly engages with the groove 30 of the rotating shaft 31 and keeps the handle 7 at an angle of 90 degrees even when the elasticity of the coil spring 122 of the section 12 is acting.

  As shown in FIG. 13 (d), since the engagement between the engagement piece 20c of the locking hook C and the engagement piece 20 of the engagement member 2 is completely disengaged, the lid can be lifted and opened. . When the lid is opened, the push button 44 of the click / stop member 4 via the push member D is not pressed, and the elasticity of the coil spring 47 is weakened, so that the protrusion 41 of the click / stop member 4 and the groove of the rotary shaft 31 The engaging shaft 2 can be easily disengaged and the rotating shaft 31 can be rotated, and the engaging member 2 together with the protrusion 23 is temporarily tightened as shown in FIG. 13A by the elasticity of the coil spring 122 of the section 12. Return to possible state.

  The scissors are provided with a pair of locking devices on both sides of the handle. In the above description, one locking device has been described, but the other locking device may be manufactured and attached symmetrically. It is.
