Description

[Technical field]

[0001] The present invention relates to a rotary lock in which a locking operation is performed by rotating a blade lever. [Background technology]

[0002] A rotary lock is a type of lock used to lock storage cases such as suitcases, coolers, safes, and chests of drawers. A rotary lock is a lock that extends a hook by lifting a blade lever and rotating it in one direction. In a rotary lock, the lock body and the hook receiver are fixed separately, for example, to the case body and its lid. By rotating the blade lever in the reverse direction to retract the protruding hook, the hook can be hooked onto the hook receiver and further tightened to lock the lock. When the hook is firmly fastened by the tension of the hook, the blade lever is tilted toward the lock mechanism of the lock body to further lock it, and the blade lever is fixed to the lock body. Since the blade lever cannot be raised or rotated, the storage case cannot be opened. [Prior art documents] [Patent documents]

Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a partial perspective view of a storage case 11 provided with a rotary lock 10 according to the embodiment. The storage case 11 is a case in which the opening of the case body 11a is closed, such as a suitcase, a cooler box, a first aid kit, or a chest of drawers. In addition, the member to which the rotary lock 10 is applied may be two members that require positioning with each other, such as a diary with a lock, in addition to the storage case 11. Hereinafter, an example will be described in which the main body portion (hereinafter referred to as the "lock main body portion") 13 of the rotary lock 10 is fixed to the case body 11a and the hook receiving portion 12 of the rotary lock 10 is fixed to the lid portion 11b, like a cooler box.

[0010] As shown in FIG. 1, the hook receiving portion 12 of the rotary lock 10 is formed by bending a T-shaped flat plate in which an "I"-shaped flat plate is connected to a "-" shaped retaining plate 18b, for example. The hook shape of the hook receiving portion 12 is formed by curving the "I"-shaped flat plate portion toward the retaining plate 18b fastened to the lid portion 11b with a screw 14. The hook 17 of the lock main body portion 13 engages with this hook receiving portion 12.

[0011] As shown in FIG. 1, the lock main body portion 13 of the rotary lock 10 mainly includes a base 18 fixed to the case body 11a, a slider 19 slidable along the base 18, a hook 17 that moves in parallel in conjunction with the slider 19, a slider cover 21 that covers the slider 19, a shaft rotation mechanism 22 for sliding the slider 19 within the slider cover 21, a blade lever 23 that is a blade-shaped rotary knob for rotating the shaft rotation mechanism 22, and a cylinder lock 24 for locking the blade lever 23.

[0012] Hereinafter, when the lock body 13 is fixed to the case body 11a, the direction in which the slider 19 slides is referred to as the "front-rear direction," the direction perpendicular to the front-rear direction on the sliding surface of the slider 19 is referred to as the "left-right direction," the direction perpendicular to both the front-rear and left-right directions that moves away from the case body 11a is referred to as the "upper," and the direction toward the case body 11a is referred to as the "lower." Furthermore, the direction in which the hook 17 protrudes due to this sliding is referred to as the "front," and the direction in which the hook 17 is retracted into the slider cover 21 is referred to as the "rear."

[0013] Next, referring to FIGS. 2 and 3 in which some of the components in the perspective view of FIG. 1 are not shown, the connection relationships of the components will be described with reference to the base 18. FIG. FIG. 2 is a perspective view of the container 11, the blade lever 23, and the screw 14 shown in FIG. 1, not shown. In FIG. 2, the slider cover 21 and the tumbler base 26 are shown by imaginary lines (dashed lines). FIG. 3 is a perspective view of FIG. 2, further showing the slider cover 21, the tumbler base 26, the two disks 22b and 22c, and the hook receiving portion 12, which are not shown. In FIG. 3, the slider 19 is shown by an imaginary line (a dashed line).

[0014] As shown in FIG. 3, the base 18 is formed, for example, by folding a single cross-shaped metal plate into a box shape with one side open. The four end faces of this metal plate are further bent outwardly of the box shape to form fastening plates 18b that come into surface contact when the opening of box 18c is aligned with case body 11a. Fastening plates 18b are fastened with screws 14 at four points, for example, to fix base 18 to case body 11a.

[0015] As shown in Figs. 2 and 3, the tumbler base 26 (Fig. 2) is fixed to the retaining plate 18e at the rear end of the base 18 together with the click spring 32. The tumbler base 26 is provided with a tumbler hole 25 (Fig. 2) having approximately the same inner diameter as the rotor 27 of the cylinder lock 24. The rotor 27 is inserted into this tumbler hole 25 from above. The rotor 27 protruding downward from this tumbler hole 25 is provided with a horizontal anti-removal slit slightly below this tumbler hole 25. A anti-removal plate 29 is fitted into this anti-removal slit. Since this anti-removal plate 29 is larger in diameter than the tumbler hole 25, the cylinder lock 24 is fixed to the tumbler base 26 and will not come out of the anti-removal slit even if an external force is applied upward.

[0016] The rotor 27 is provided with a head portion 37 having a key hole 28 for axially rotating the rotor 27 relative to the tumbler hole 25 with a key. The head portion 37 has a shape in which an elliptical shape having a major axis in a direction perpendicular to the keyhole direction is superimposed on a disk shape. By using the key to orient the keyhole 28 in the left-right direction, the long axis of this elliptical shape faces the front-to-rear direction, and as shown in Figure 1, the head portion 37 presses down from above on the blade lever 23 with the cylinder lock 24 hooked in the engagement hole 39 of the blade lever 23, thereby fixing it in place.

[0017] A pair of left and right rectangular slit holes 41 are provided in the box ceiling surface 18a of the base 18 along the longitudinal direction in the front-rear direction. A pair of left and right two-stage slit holes 42 are provided in front of the rectangular slit hole 41, the front side of which opens wider toward the left-right center line of the box ceiling surface 18a than the rear side. The rectangular slit hole 41 and the two-stage slit hole 42 receive projections 46 and 47 of the slider cover 21 .

[0018] Here, FIG. 4 is a perspective view of the slider cover 21 viewed from the lower left. 4, the slider cover 21 is formed in a box shape with two opposing sides of a cross-shaped metal plate folded back twice in the same direction to form a slide rail 21c facing inward. The slider 19 is accommodated between the ceiling part 21a of the slider cover 21 and the slide rail 21c so as to be slidable on the slide rail 21c. The rear end side of the ceiling part 21a is folded downward once to cover the rear end of the slide rail 21c.

[0019] In addition, on the inner sides of the left and right slide rails 21c, a pair of left and right anti-detachment claws 46 and restraining spring locking claws 47 are aligned in front and behind and protrude downward, respectively, aligned with the rectangular slit hole 41 and the two-stage slit hole 42. The anti-detachment claws 46 are bent further inward toward the axis of symmetry C of the slider cover 21 so that they can be inserted into the opening on the wider side of the two-stage slit hole 42 and have substantially the same shape as this opening. In addition, the restraining spring locking claw 47 has substantially the same shape as the rectangular slit hole 41 so that it can be inserted into the rectangular slit hole 41 .

[0020] The removal prevention claw 46 and the suppression spring locking claw 47 are inserted into the rectangular slit hole 41 and the two-stage slit hole 42 and then shifted slightly backward, so that the removal prevention claw 46 fits into the narrow opening of the two-stage slit hole 42, and the slider cover 21 is fixed to the base 18. A rear notch 56 is provided at the rear of the suppression spring locking claw 47 so that the plate at the rear end of the rectangular slit hole 41 can fit in. This rear notch 56 allows the slider cover 21 to slide slightly in the front-rear direction on the base 18.

[0021] Returning to FIG. 2 and FIG. 3, the description of each member will continue. As shown in FIG. 2, the slider 19 is formed by bending, for example, a metal plate having left and right end portions extending forward into a rectangular flat plate 19a. The left and right edge portions have their front ends curved to form two cylinders 19b on the left and right. A single pivot rod 49 is installed in the left-right direction between the left and right cylinders 19b. The left and right end portions having the cylinders 19b are bent so as to form projections and recesses in the up-down direction, forming slide legs 19c that slide on the slide rails 21c.

[0022] Furthermore, a rotation limiting plate 51 is lowered one step downward from the left-right central portion of the front end of the flat plate 19 a of the slider 19 and then bent to protrude toward a position slightly lower than the central axis of the swing rod 49 . Further, the rear end of the hook 17 is connected to the pivot rod 49 so that the hook 17 can rotate. A curved cylindrical connecting tube 17a is formed at the plate-like rear end of the hook 17. By passing the pivot rod 49 through this connecting tube 17a, the hook 17 is connected to the pivot rod 49 so as to be rotatable around the pivot rod 49.

[0023] Further, the connecting cylinder 17a is provided with a rotation limiting hole (opening) 52 into which a rotation limiting plate 51 of the slider 19 is inserted. Here, FIG. 5 is a side cross-sectional view of the configuration around the hook 17. The rotation limiting hole 52 is provided within a range in which it is desired to allow rotation of the hook 17, such as an opening angle of about 90°. By inserting the rotation limiting plate 51 into the rotation limiting hole 52, the axial rotation of the hook 17 is limited to a range in which the lower or upper edge of the rotation limiting hole 52 abuts against the rotation limiting plate 51.

[0024] 2 and 3, a spring-up spring (biasing portion) 34, which is a torsion spring, is wound around the pivot rod 49 so as to sandwich the hook 17. The abdomen of the spring-up spring 34 is disposed under the hook 17 and applies a force to make the hook 17 spring up upward. The end of the winding of the spring-up spring 34 is hooked from below and fastened to the pivot rod 49, for example, on the upper surfaces of the left and right slide legs 19c of the slider 19. By arranging the spring-up spring 34 in this manner, a force is constantly applied to the hook 17 to spring it up upward. The biasing portion 34 is not limited to a torsion spring, but may be a leaf spring, a disc spring, or even a combination of a plurality of springs. Moreover, the fixing destination of the biasing portion 34 is not limited to the pivot rod 49, but may be the slider 19, for example.

[0025] In addition, the slider 19 is provided with a shaft rotation mechanism 22 as shown in FIGS. The shaft rotation mechanism 22 is composed of a rotation shaft 22a positioned on the slider cover 21, two disks (a lever connection disk 22b and a rotation transmission disk 22c) with different diameters that rotate around the rotation shaft 22a, and a cap 22d. The rotation shaft 22a connects the two disks 22b and 22c and the cap 22d by crimping. Of the two disks, the lever connection disk 22b having the smaller diameter is provided with a lever notch 45 into which the hook claw 23a of the blade lever 23 is fitted.

[0026] After the blade lever 23 is fitted into the lever notch 45, the cap 22d is placed from above, and the blade lever 23 is fixed to the shaft rotation mechanism 22. The blade lever 23 fitted and fixed into the lever notch 45 can be raised or lowered at any angle on the slider cover 21 with the hook claw 23a as the axis. The blade lever 23 can also be twisted around the rotation shaft 22a.

[0027] The lever connecting disk 22b is fitted into a disk hole 21b (FIG. 4) provided in the slider cover 21 at approximately the center in the front-rear and left-right directions of the ceiling portion 21a, and has a diameter slightly larger than that of the lever connecting disk 22b, as shown in FIG. The rotation transmitting disk 22c is disposed between the slider cover 21 and the slider 19, and is fixed to the slider cover 21 by being crimped to the rotation shaft core 22a together with the lever connecting disk 22b and the cap 22d. Since the diameter of the rotation transmission disk 22c is larger than the disk hole 21b, the rotation transmission disk 22c remains between the slider cover 21 and the slider 19.

[0028] Fig. 6 is a perspective view of the blade lever 23 and the shaft rotation mechanism 22 viewed from the bottom left. In Fig. 6, the shaft rotation mechanism 22 other than the rotation shaft core 22a is shown by imaginary lines. A rotation transmission protrusion 22f is provided on the bottom surface of the lever connection disk 22b to transmit the rotation of the lever connection disk 22b to the rotation transmission disk 22c. The rotation transmitting disk 22c is provided with a rotation transmitting hole 22e into which the rotation transmitting protrusion 22f is fitted. Furthermore, a rotational motion protrusion 22g is provided on the bottom surface of the rotational transmission hole 22e. When the blade lever 23 is rotated, the rotary motion protrusion 22g revolves around the rotary shaft 22a via the lever connection disk 22b. In addition, the two disks 22b and 22c may be molded integrally as appropriate. When the lever connecting disk 22b and the rotation transmitting disk 22c are molded integrally, the rotational motions of the disks 22b and 22c are also integrated, so that the rotation transmitting protrusion 22f and the rotation transmitting hole 22e do not need to be provided.

[0029] Next, the arrangement of each component on the back surface of the lock body 13 will be described with reference to Figs. FIG. 7 is a rear view showing the arrangement of each member inside the slider cover 21. As shown in FIG. That is, this is a rear view showing the lock body 13 excluding the base 18, the tumbler base 26, the cylinder lock 24 and the blade lever 23. FIG. 8 is a rear view showing the arrangement of each member inside the base 18. As shown in FIG. In FIG. 8, the components other than those arranged on the box ceiling surface 18a of the base 18 are omitted from the illustration.

[0030] The rotation transmission disk 22c of the shaft rotation mechanism 22 is disposed between the slider cover 21 and the slider 19 as described above. 7, the rotational motion protrusion 22g of the rotation transmission disk 22c is fitted into a movement hole 57 provided in the flat plate 19a of the slider 19. As shown in FIG. The movement hole 57 is a so-called racetrack-shaped hole or groove in which two circles on the left and right sides, each having a diameter approximately the same as that of the rotational movement protrusion 22g, are connected by two parallel straight lines.

[0031] When the rotary motion protrusion 22g rotates around the rotary shaft 22a, the slider 19 also tries to rotate in response to this rotation. However, the slider 19 is restricted from sliding left and right by the slider cover 21, so it can only slide forward and backward. Here, since the movable hole 57 has a racetrack shape, the left-right movement of the rotational motion protrusion 22g can be absorbed by the rotational motion protrusion 22g moving left-right within the movable hole 57, without the need to slide the slider 19 left-right.

[0032] That is, the circular motion of the rotational motion protrusion 22g can be maintained by combining the left-right motion within the moving hole 57 and the front-rear motion of the slider 19. That is, by combining the rotation transmission disk 22c and the moving hole 57, the twisting of the blade lever 23 is converted into the linear motion of the slider 19. In other words, the shaft rotation mechanism 22 and the slider 19 are combined to constitute a motion conversion mechanism that converts the rotational motion of the blade lever 23 into the linear motion of the hook 17.

[0033] As described above, the restraining spring locking claws 47 protrude downward from the left and right rectangular slits 41 provided in the box ceiling surface 18 a of the base 18 . As shown in FIGS. 7 and 8, the arms 36a of the restraining spring 36, which is a torsion spring, are hooked on the left and right sides in the front cutouts 55 of the restraining spring locking claws 47, respectively.

[0034] The arm portion 36 a is bent forward slightly to the left and right from the position where it is hooked onto the restraining spring locking claw 47 and is disposed along the box-like side surface of the base 18 . The suppression spring 36 is in contact with the box side surface on the front side of the base 18. The retaining plate 18b is bent forward from the box side surface on which the suppression spring 36 is in contact, and a rectangular cut is made in a portion of the retaining plate 18b from the box side surface on the front side to the center of the retaining plate 18b, leaving one side along the box side surface. Then, this portion is bent from the box side surface on the front side to the opposite side to the retaining plate 18b to become the pressing plate 18d that holds the suppression spring 36 inside the box of the base 18. Due to such an arrangement of the restraining spring 36 , when the slider cover 21 attempts to be displaced forward relative to the base 18 , the slider cover 21 receives a spring force in the rearward direction via the restraining spring engaging claw 47 .

[0035] 9(A) and (B) are explanatory diagrams illustrating the relationship between the deformation of the restraining spring 36 and the displacement of various members. Both of Figures 9(A) and (B) show the back side of the rotary lock 10. FIG. 9(A) shows the rotary lock 10 in an unlocked state. When the rotary lock 10 is in the unlocked state, the hook 17 is pulled out to a moderate extent, so that no force is applied to the slider cover 21 pulling it forward.

[0036] FIG. 9(B) shows the rotary lock 10 in the locked state. In the locked state of the rotary lock 10, the hook 17 is pulled into the slider cover 21 to the maximum extent, and the blade lever 23 is hooked onto the cylinder lock 24. In other words, the rotational motion protrusion 22g of the rotation transmission disk 22c is closer to the cylinder lock 24. Therefore, since the distance between the hook 17 and the lever connecting disc 22b is at a minimum, the distance between the hook receiving portion 12 and the lever connecting disc 22b is also at a minimum.

[0037] On the other hand, since the lever connecting disk 22b is fitted into the slider cover 21 and slides integrally therewith, the slider cover 21 also slides forward on the base 18 and approaches the hook receiving portion 12 closest to the slider cover 22b. As a result, the restraining spring locking claw 47 moves forward relative to the rectangular slit hole 41, and pushes the arm portion 36a of the restraining spring 36 forward.

[0038] The force of this restraining spring locking claw 47 causes the restraining spring 36 to bend in the direction in which it becomes more wound, and the restoring force of this bending elastically pushes back the restraining spring locking claw 47. As a result, a rearward force is applied to the slider cover 21. In addition, since the slider cover 21 and the slider 19 are connected via the shaft rotation mechanism 22, a rearward elastic force is also applied to the hook 17 by the restraining spring 36. Therefore, when the blade lever 23 is locked by the cylinder lock 24, a force acts on the hook 17 in a direction tightening the engagement with the hook receiving portion 12.

[0039] Next, the operation of the rotary lock 10 configured in this manner will be described with reference to Figures 10(A) to (D). First, from a state in which the slider 19 is pulled out to its maximum extent, the blade lever 23 is rotated in one direction, for example, by 30°, as shown in Fig. 10(A). At this time, the rotary motion protrusion 22g rotates backward, so that the slider 19 is pulled into the inside of the slider cover 21. At this time, the hook 17 is still not in contact with the slider cover 21, so the hook 17 is in a state in which it is bounced up by the spring force of the bounce-up spring 34.

[0040] Next, as shown in Figure 10 (B), when the blade lever 23 is rotated 80 degrees from the initial state, the rotary motion protrusion 22g rotates further toward the cylinder lock 24, and the slider 19 is pulled further into the slider cover 21. At this time, the upper surface of the hook 17 hits the lower surface of the ceiling part 21a of the slider cover 21, and the tip of the hook 17 is tilted horizontally against the spring force of the spring 34.

[0041] 10(C), the blade lever 23 is further rotated 120° from the initial state. At this time, the hook 17 is further drawn into the slider cover 21 and tilted to a substantially horizontal state. Then, the hook 17 is caught by the hook of the hook receiving portion 12.

[0042] When the blade lever 23 is further twisted and rotated 180° from the initial state as shown in FIG. 10(D), the rotational motion protrusion 22g, the rotational axis 22a, and the cylinder lock 24 are aligned in a straight line, and the rotational motion protrusion 22g approaches the cylinder lock 24. At this time, the hook 17 tries to be pulled into the slider cover 21 to the maximum extent, but since the hook 17 is hooked on the hook receiving portion 12 , the slider cover 21 tries to approach the hook receiving portion 12 . When the slider cover 21 approaches the hook receiving portion 12 and attempts to displace forward on the box ceiling surface 18a of the base 18, the restraining spring 36 bends and applies a rearward force to the slider cover 21.

[0043] Therefore, the slider cover 21 is displaced forward by a distance δ of, for example, several mm compared to when no force is applied, and receives both the restoring force of the restoring spring 36 and the resistance from the hook receiving portion 12 against the restoring force of the restoring spring 36. Therefore, when the blade lever 23 is rotated 180° from the initial state, a force fastening the hook 17 and the hook receiving portion 12 is constantly generated. In this state, when the blade lever 23 is tilted toward the cylinder lock 24 and the cylinder lock 24 is rotated with a key, the head portion 37 of the cylinder lock 24 presses the upper surface of the blade lever 23 to lock it.

[0044] Therefore, the rotary lock 10 can be put into a locked state simply by rotating the blade lever 23 when the hook 17 is in the raised position. Furthermore, after the cylinder lock 24 is locked, by further rotating the blade lever 23 in the reverse direction, the rotary lock 10 is automatically unlocked by operating only the blade lever 23 in the same manner. That is, when unlocking, the tightening between the hook receiving portion 12 and the hook 17 is released by simply twisting the wing lever 23, and the hook 17 is gradually pulled out and flipped up.

[0045] As described above, the rotary lock 10 according to the embodiment provides the following effects. (1) By using the spring 34, when the hook 17 is pulled out from the slider cover 21, the hook 17 bounces up and rotates about the pivot rod 49. Therefore, the hook 17 can be disengaged from the hook receiver 12 by simply twisting the blade lever 23, and the rotary lock 10 can be opened.

[0046] (2) By using the slider 19, the hook 17, which is raised when unlocking, gradually approaches a horizontal state as it is pulled into the slider cover 21, and can be fitted into the hook receiving portion 12. Therefore, the lock can be locked by simply twisting the blade lever 23 half a turn. In other words, the rotary lock 10 combines a typical rotary lock with a one-stroke locking mechanism.

[0047] (3) By providing the rotation limiting hole 52 in the hook 17 and inserting the rotation limiting plate 51, it is possible to prevent the hook 17 from rotating endlessly when it is lifted up. This prevents the hook 17 from flapping when locking or unlocking, improving operability. In addition, the design surface of the hook 17 remains prominent even after unlocking, giving the viewer a stylish impression of the design.

[0048] (4) By fitting the restraining spring 36 into the front notch 55 of the restraining spring locking claw 47, the restraining spring 36 can be prevented from coming off the base 18 of the slider cover 21.

[0049] (5) The slider cover 21 is displaceably connected to the base 18 and elastically fixed by the restraining spring 36, so that a fastening force between the hook 17 and the hook receiving portion 12 can be generated.

[0050] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope of the invention and its equivalents as described in the claims, as well as in the scope and spirit of the invention.

[0051] For example, although an example has been described in which the base, the hook receiving portion, and the cylinder lock base are fastened with screws, the fasteners are not particularly limited to this and may be, for example, bolts and nuts. Moreover, the cylinder lock is shown as a typical example, and any known or commercially available cylinder lock may be used.
