Description

Set of locking device and card key making tool, and card key making tool

The present invention relates to a set of a locking device that is unlocked by a card key in which a key hole is formed and a card key making tool for making the card key, and a card key making tool that constitutes this set.

Conventionally, for example, in public facilities used by an unspecified large number of people such as hotels, umbrella stands for individually holding umbrellas such as rain umbrellas or parasols are installed. In such an umbrella stand, there is one in which a plurality of umbrella holding devices (locking devices) configured to be able to hold an umbrella handle in a locked state are provided on an upper portion of a stand. As such an umbrella stand locking mechanism, there is a type that unlocks by unlocking a card key by inserting a card key.

An example of a conventional umbrella holding device that unlocks using a card key and a locking mechanism used therefor are shown in FIGS. 31 to 36, for example. As shown in FIG. 32, the locking mechanism Y includes a slide block 140 that is slidably supported in the body 110. As shown in FIG. 32, a plurality of holes 141 are formed in the slide block 140. As shown in FIG. 32, the plurality of holes 141 are provided in two rows along both side edges. Each hole 141 is formed with a vertical groove 141 a that passes through the outer side edge of the slide block 140. For example, two lock pins 160 are inserted into two holes 141 (one hole 141 selected from each of the two rows). As shown in FIGS. 32 and 34, the lock pin 160 has a conical tip portion 161 and a columnar portion 162, and a protrusion 163 is provided near the upper portion of the columnar portion 162. The lock pin 160 is inserted into the hole 141 such that the protrusion 163 passes through the vertical groove 141a and protrudes from the side surface in the Cs direction or the Op direction. A spring 168 is provided below the lock pin 160. Thereby, the lock pin 160 is regulated by the hole 141 and the vertical groove 141a and can reciprocate in the vertical direction in the drawing in FIG. 34, and is urged upward in the drawing by the spring 168. In the protrusion 163, a portion protruding from the vertical groove 141a enters the guide groove 151 of the

guide blocks

150A and 150B shown in FIG. Note that, as shown in FIG. 32, the slide block 140 is urged toward the Out direction by a spring 178.

The guide blocks 150A and 150B are spaced apart so as to sandwich the slide block 140. A guide groove 151 is formed on the surface of the

guide blocks

150A and 150B facing the slide block 140. The guide groove 151 corresponds to the vertical groove 141a of the slide block 140 as shown in FIGS. A plurality of vertical grooves 151v arranged so as to intersect with a horizontal groove 151h perpendicular to the vertical grooves 151v. The lock pin 160 is positioned at the upper end by the biasing force of the spring 168. At this time, the protrusion 163 is located at the upper end 151vu above the vertical groove 151v, and the slide block 140 is in a locked state in which movement relative to the

guide blocks

150A and 150B is restricted. At this time, the front end portion 161 of the lock pin 160 protrudes from the upper surface of the slide block 140.

The lock state in this locking mechanism Y is released by the card key 120 shown in FIG. The card key 120 is formed with two key holes 120a. These key holes 120a are formed by selecting from a plurality of drilling positions. The two key holes 120a are formed so that the positions of the card key 120 in the insertion direction and the width direction coincide with the two lock pins 160 when the card key 120 is inserted through the insertion port 112 and is in a predetermined insertion state. ing. In the movement process in which the card key 120 is inserted from the insertion slot 112, the card key 120 moves along the upper surface of the slide block 140, and each lock pin 160 is pushed down to the lower surface of the card key 120. Then, as shown in FIG. 35, when the card key 120 is inserted until the tip of the card key 120 abuts against the abutting portion 144, the positions of the lock pin 160 and the key hole 120a coincide. At this time, the lock pin 160 is raised by the urging force of the spring 168 to a position where the upper part of each tip portion 161 enters the corresponding key hole 120a. The dimension of the lock pin 160 and the dimension of the key hole 120a that correspond to each other have a dimension relationship in which the distal end portion 161 of the lock pin 160 stops without completely penetrating the key hole 120a. In this state, the protrusion 163 of each lock pin 160 is positioned at the height of the horizontal groove 151h. Thereby, the locking action by fitting the protrusion 163 and the vertical groove 151v is released, and the slide block 140 is slidable in the In direction. When the card key 120 is further pushed in the In direction from the state shown in FIG. 35, the tip of the card key 120 pushes the abutting portion 144 as shown in FIG. 36, and each key hole 120a pushes each lock pin 160. Thus, the slide block 140, the lock pin 160, and the lock lever 170 supported by the slide block 140 are integrally slid and moved in the In direction against the spring 178. As a result, the stopper 171 of the lock lever 170 that has entered the slide path of the bar 131 and held the shutter 130 in the closed state is retracted from the slide path. As a result, the locked state of the locking mechanism Y is released, and the shutter 130 is moved to the open position by the biasing force of the spring 138.

In an umbrella stand or the like configured using a plurality of umbrella holding devices X, in the locking mechanism having the above-described configuration equipped in each umbrella holding device, the arrangement of the lock pins 160 with respect to the holes 141 of the slide block 140 is changed. By using the card key 120 in which the key hole 120a is formed at the corresponding position, the card key 120 can be distinguished and used as a dedicated card key 120 suitable only for each umbrella holding device. In the configuration shown in FIG. 32, when the lock pins 160 are inserted into the holes 141 of the slide block 140, for example, one hole 141 selected from each of the two rows, the arrangement of the 16 lock pins 160 is arranged. There are combinations. In this case, the 16 types of locking mechanisms Y (16 umbrella holding devices X) can be unlocked with dedicated card keys 120 each having a different key hole 120a formation position. Therefore, the locking mechanism Y having such a configuration is suitable for increasing the number of umbrella holding devices X that can be used simultaneously.

However, in the conventional umbrella holding device X, the user of the umbrella stand may lose the card key 120. If the card key 120 is lost, the business operator who installs the umbrella stand (the owner of the umbrella stand) is the same card key 120 ( It is necessary to request the production of a spare key. Then, the manufacturer of the umbrella holding device X produces a spare key in which the key hole 120a is formed at the same position as the lost card key 120 and delivers it to the owner of the umbrella stand. Until then, the umbrella holding device X corresponding to the lost card key 120 cannot be used, which is inconvenient. The owner of the umbrella stand may purchase a set of spare keys in advance, but it is expensive and cumbersome to manage, so it is not an appropriate countermeasure and there is still room for improvement.

Each of the pair of

guide blocks

5A and 5B is a flat plate-like block, and is disposed so as to sandwich the slide block 4 therebetween. The guide blocks 5A and 5B have a substantially symmetrical structure. The guide block 5A will be described below, but the guide block 5B has the same configuration except for differences described later. As shown in FIGS. 5 and 7, the guide block 5A has two

protrusions

53a and 53b that protrude in the vertical direction. By inserting these

protrusions

53a and 53b into holes of the lower body 1B and the upper body 1A through

holes

81 and 91 of the upper plate 8 and the lower plate 9 described later, the guide block 5A is fixed to the body 1. Yes.

A guide groove 51 and a slide groove 52 are formed on the surface of the guide block 5A facing the Op direction. In the guide groove 51, a plurality of vertical grooves 51v arranged in the In-Out direction and a horizontal groove 51h extending in the In-Out direction intersect each other. The horizontal groove 51h intersects at a portion slightly above the center of each of the plurality of vertical grooves 51v. Each vertical groove 51v is partitioned into an upper end 51vu above the horizontal groove 51h and a lower end 51vd below the horizontal groove 51h. The two slide grooves 52 are provided near the lower end of the guide block 5A, and are relatively short grooves extending in the In-Out direction. The guide block 5B also has the same guide groove 51, slide groove 52, and

protrusions

53a and 53b as the guide block 5A. The guide grooves 51 of the guide blocks 5A and 5B are positioned so as to oppose each other, but the positional relationship in the In-Out direction of the vertical grooves 51v differs depending on the arrangement of the holes 41 of the slide block 4 described later. ing.

As shown in FIGS. 5 and 6, the slide block 4 has a substantially rectangular parallelepiped shape and is provided so as to be sandwiched between a pair of

guide blocks

5A and 5B. The slide block 4 includes a pair of

side portions

4A and 4B located on both side edges, and a top plate 4C that connects these

side portions

4A and 4B. As shown in FIGS. 5, 8, and 9, two protrusions 42 protruding in the Cs direction or the Op direction are provided near the lower ends of the side portions 4 A and 4 B. These protrusions 42 are inserted into the slide grooves 52 of the guide blocks 5A and 5B. Thus, the slide block 4 is supported so as to be slidable by the length of the slide groove 52 in the In-Out direction. As will be described later, the slide block 4 takes a lock position slid toward the Out direction and a lock release position slid toward the In direction. Abutting portions 44 that protrude from the top surface of the top plate 4C are provided at portions other than both ends in the Cs-Op direction at the back end in the In direction of the top plate 4C. The abutting portion 44 is for restricting the insertion depth of the card key 2 from the insertion port 12.

As shown in FIG. 6, the

side portions

4A and 4B of the slide block 4 are each provided with a plurality of holes 41 arranged along the In-Out direction. These holes 41 are provided in the same arrangement as a plurality of drilling positions in the card key 2 described above. In the present embodiment, the plurality of holes 41 provided in the side portion 4A and the plurality of holes 41 provided in the side portion

4B form rows

40A and 40B that are separated from each other in the Cs-Op direction. The plurality of holes 41 constituting the row 40A are arranged at a constant pitch (6.3 mm), for example. On the other hand, the plurality of holes 41 constituting the row 40B are not arranged at a constant pitch. For example, the pitches of the first and second holes 41 and the third and fourth holes 41 from the In direction are 7 mm. On the other hand, the pitch of the second and third holes 41 from the In direction is 10 mm. With such a configuration, paying attention to a set of one hole 41 selected from the

rows

40A and 40B, the positional relationship in the In-Out direction of the holes 41 forming each set is different for each set. As shown in FIGS. 6 and 9, each hole 41 is formed with a vertical groove 41 a that passes through the outside of the slide block 4.

As shown in FIG. 6, the lock pin 6 is inserted into any of the plurality of holes 41. In the present embodiment, for example, two lock pins 6 are inserted into two holes 41 as shown, and these two holes 41 are selected one by one from the

rows

40A and 40B. The number of lock pins 6 used in each umbrella holding device B and in which hole 41 the lock pin 6 is inserted are set uniquely for each umbrella holding device B. These correspond to the number and arrangement of the key holes 2a of the card key 2 described above.

As shown in FIG. 6 and FIG. 9, the lock pin 6 has a conical tip portion 61 and a cylindrical portion 62. A protrusion 63 is provided on the upper portion of the cylindrical portion 62. The top of the tip 61 has a diameter smaller than the inner diameter of the key hole 2 a of the card key 2. On the other hand, the cylindrical portion 62 has a diameter larger than the inner diameter of the key hole 2a. The lock pin 6 is inserted into the hole 41 so that the protrusion 63 penetrates the vertical groove 41a and protrudes in the Cs direction or Op direction. A spring 68 is provided below the lock pin 6. Thereby, the lock pin 6 is regulated by the hole 41 and the vertical groove 41a and can reciprocate in the vertical direction in the figure, and is urged upward by the spring 68 in the figure. The protrusion 63 protrudes from the longitudinal groove 41a into the guide groove 51 of the guide blocks 5A and 5B shown in FIG. Accordingly, as described later, the slide block 4 can be selected to be slidable as the lock pin 6 moves up and down.

As shown in FIGS. 6 and 8, a lock lever 7 is disposed in a space 4D sandwiched between the

side portions

4A and 4B of the slide block 4. As shown in FIG. 8, the lock lever 7 has a substantially T-shaped cross section and includes a horizontal portion 7A and an upright portion 7B.

As can be seen from FIG. 5 and FIG. 9, a pair of support pins 73 projecting in the Cs-Op direction is provided at the lower end of the standing portion 7B. The pair of support pins 73 are inserted into a pair of pin grooves 43 formed on the bottom side of the pair of

side portions

4A, 4B of the slide block 4 in the lower end In direction. Further, the lower plate 9 is in contact with the lower surfaces of the

side portions

4A and 4B, and the vertical movement of the support pins 73 is prevented. Thereby, the lock lever 7 is supported so as to be rotatable around the support pin 73 with respect to the slide block 4.

The tip of the horizontal portion 7A protrudes in the Out direction from the

side portions

4A and 4B of the slide block 4. As shown in FIG. 6, a stopper 71 that is wide in the Cs-Op direction is formed at the tip. The stopper 71 enters the slide path of the shutter engaging portion 34 when the slide block 4 is slid in the Out direction with the shutter 3 being moved to the closed position by the user, and closes the shutter 3. It locks so that it can be fastened.

As shown in FIGS. 5 and 6, the upper portion of the upright portion 7 B has a bifurcated shape so as to follow the concave portion 45 formed on the surface facing the In direction of the side portions 4 A and 4 B of the slide block 4. Is exposed. As shown in FIG. 8, a spring 78 is provided between the standing portion 7B and the back plate 1Ab of the upper block 1A. Thereby, the lock lever 7 is urged so that the upright portion 7 B is pressed against the side portions 4 A and 4 B of the slide block 4. Near the upper end of the bifurcated portion of the upright portion 7B is a lock release portion 72. The unlocking portion 72 is in an initial position where the upright portion 7B is pressed against the

side portions

4A and 4B and in a state where the entire lock lever 7 is rotated in the In direction against the biasing force of the spring 78. Take a certain unlocked position. When the unlocking portion 72 is in the unlocked position, even if the slide block 4 is in the locked position, the stopper 71 that holds the shutter 3 in the closed position is shown in the upper right direction in FIG. And the shutter 3 is unlocked. As shown in FIG. 6, the bifurcated unlocking portions 72 are positioned at both ends in the Cs-Op direction with respect to the abutting portion 44 provided at the back end in the In direction of the top plate 4C. The unlocking position of the unlocking part 72 is set to the back in the In direction relative to the abutting part 44.

The upper plate 8 and the lower plate 9 are for assembling the locking mechanism C so that the slide block 4 is properly sandwiched between the guide blocks 5A and 5B. As shown in FIG. 5, the upper plate 8 is formed with holes 81 at four corners for fitting the protrusions 53a protruding upward in the guide blocks 5A and 5B. The lower plate 9 is formed with holes 91 at four corners for fitting the protrusions 53b protruding downward in the guide blocks 5A and 5B. In a state where the projections 53a of the guide blocks 5A and 5B are fitted into the holes 81 of the upper plate 8 and the upper plate 8 is brought into contact with the upper portions of the guide blocks 5A and 5B, as shown in FIGS. Between the upper surface of the slide block 4 and the lower surface of the upper plate 8, an insertion path 4E for the card key 2 consisting of a predetermined space is formed.

As shown in FIG. 5 and FIG. 11, two slits 82 are formed on the back end of the upper plate 8 in the In direction at positions near both ends in the Cs-Op direction. Since these slits 82 are formed, interference between the unlocking portion 72 and the upper plate 8 is prevented during the movement of the unlocking portion 72 of the lock lever 7 from the initial position to the unlocking position. Near the both ends of the upper plate 8 in the width direction, a plurality of holes 83 for preventing interference with the front end portion 61 of the lock pin 6 are formed. Further, an opening 84 located in the center in the Cs-Op direction is formed near the back of the upper plate 8 in the In direction. In the center of the upper plate 8 in the Cs-Op direction, a round bar portion 85 extending in the Cs-Op direction is provided so as to cross the opening 84.

Rotating member 20 is substantially T-shaped in plan view, and has a pair of lock release restricting protrusions 21 protruding in the Cs-Op direction, protruding pieces 22, and recessed groove parts 23. As shown in FIG. 8, the round bar portion 85 of the upper plate 8 is fitted into the concave groove portion 23. Thereby, the rotation member 20 is supported so as to be rotatable around the round bar portion 85 with respect to the upper plate 8.

As shown in FIGS. 8 and 9, the rotating member 20 normally overlaps the upper plate 8 by its own weight. At this time, the protruding piece 22 has entered the insertion path 4E of the card key 2 through the opening 84 of the upper plate 8, and is in the entry position. Further, the projecting piece 22 at this entry position is located in the vicinity of the abutting portion 44. Here, as shown in FIGS. 9 and 11, the lock release restricting protrusion 21 is located further in the In direction than the lock release portion 72 of the lock lever 7. Thereby, the unlocking part 72 is prevented from moving inward in the In direction. Therefore, the lock lever 7 does not take the above-described unlocking position that is rotated in the In direction, and the slide block 4 takes the above-described unlocking position that is slid toward the In direction. Nor.

On the other hand, when the card key 2 is inserted into the insertion path 4E from the insertion opening 12 and the tip of the card key 2 is brought into contact with the abutting portion 44, the protruding piece 22 is brought into contact with the card key 2 as shown in FIG. Pushed and retracted from the insertion path 4E, the rotating member 20 rotates. When the protruding piece 22 is in the retracted position, the pair of lock release restricting protrusions 21 are displaced upward, and the lock release part 72 of the lock lever 7 can move inward in the In direction.

As shown in FIGS. 4, 6, 8 and 10, the lower body 1B is provided with a slide lock pin 16 in the vicinity of the front plate 1Bb near the Out direction. The slide lock pin 16 has a protrusion 16a at the tip, a columnar part 16b, and a cam 16c. The cylindrical portion 16b is inserted into a hole formed in the lower body 1B. The cam 16c is along the front plate 1Bb. A spring 18 is provided below the slide lock pin 16. Thereby, the slide lock pin 16 is regulated by the hole and the front plate 1Bb, can reciprocate in the vertical direction in the figure, and cannot rotate, and is biased upward by the spring 18 in the figure.

When the slide block 4 is positioned near the Out direction and is in the locked position, the protrusion 16a of the slide lock pin 16 is in contact with the lower surface of the slide block 4, and the slide lock pin 16 resists the biasing force of the spring 18. And is allowed to settle downward. On the other hand, as shown in FIG. 18, when the slide block 4 is located closer to the In direction and is in the unlocked position, the slide lock pin 16 moves upward by the urging force of the spring 18. At this time, the protruding portion 16a has appeared higher than the lower surface of the slide block 4, and the movement of the slide block 4 in the Out direction is locked.

As shown in FIGS. 12 and 13, the block body 200 has a plurality of holes 201 extending vertically. In the present embodiment, the plurality of holes 201 are divided into a large-diameter hole group 201A and a small-diameter hole group 201B configured by half of these holes 201. The arrangement of the plurality of holes 201 constituting the large-diameter hole group 201A and the arrangement of the plurality of holes 201 constituting the small-diameter hole group 201B respectively correspond to the plurality of drilling positions set in the card key 2. It is in a positional relationship.

As shown in FIG. 14, the holes 201 constituting the large-diameter hole group 201A include an upper hole 211a formed in the upper block 210, and a lower portion formed coaxially with the upper hole 211a in the lower block 220. It consists of holes 221a. The diameters of the upper hole 211a and the lower hole 221a have dimensions corresponding to the key hole 2a of the card key 2 shown in FIG. The small diameter hole group 201B includes an upper hole 211b formed in the upper block 210 and a lower hole 221b formed coaxially with the upper hole 211b in the lower block 220. The diameter of the upper hole 211b is a dimension corresponding to the key hole 2a of the card key 2 shown in FIG. 4, while the diameter of the lower hole 221b is smaller than the diameter of the upper hole 211b, which will be described later. The size corresponds to the key hole 2a of the card key 2 shown in FIG.

As shown in FIG. 13, different marks 202 are provided in the vicinity of the holes 201 so as to correspond to the respective holes 201. In this embodiment, the mark 202 of the hole 201 constituting the large-diameter hole group 201A and the mark 202 of the hole 201 constituting the small-diameter hole group 201B are in a correspondence relationship. For example, uppercase letters of the alphabet are used as the marks 202 of the holes 201 constituting the large diameter hole group 201A, and lowercase letters of the alphabet are used as the marks 202 of the holes 201 constituting the small diameter hole group 201B. The same alphabet is used for the notation 202 of the hole 201 of the large-diameter hole group 201A and the notation 202 of the hole 201 of the small-diameter hole group 201B for the corresponding positional relationship.

As described above with reference to FIG. 3, the lower body 1 B of the umbrella holding device B is provided with the mark 19. This mark 19 is in the hole 201 in the same positional relationship as the hole 41 (see FIG. 6) in which the lock pin 6 is inserted in the slide block 4 of the umbrella holding device B among the holes 201 of the card key making tool F. It is the same as the corresponding title 202.

Next, how to use the umbrella holding device B and the card key making tool F will be described below with reference to FIGS.

15 to 18 show a method of releasing the locked state of the umbrella holding device B shown in FIG. 6 in which the umbrella receiving portion 11 is locked in the closed state by using the card key 2 to open the umbrella receiving portion 11. Is shown.

FIG. 15 shows the umbrella holding device B in which the locking mechanism C is in the locked state. The bar 31 has taken the closed position which makes the umbrella receiving part 11 of FIG. 6 a closed state. The slide block 4 is urged in the Out direction by the spring 78 via the standing portion 7B of the lock lever 7, and the protrusion 42 is positioned closer to the Out direction in the slide groove 52 of the guide blocks 5A and 5B. ing. This position is the lock position of the slide block 4. Further, the lock pin 6 is biased upward by a spring 68, and the protrusion 63 is in the upper end portion 51 vu of the vertical groove 51 v in the guide groove 51. As a result, the slide block 4 is in a state in which it cannot slide in the In-Out direction. In this state, the stopper 71 protrudes into the slide path of the shutter engaging portion 34. Thereby, the shutter 3 is locked in the closed position.

Next, in order to release the locked state of the locking mechanism C, the card key 2 is inserted from the insertion slot 12 into the insertion path 4E as shown in FIG. In the process in which the card key 2 is inserted in the In direction, the card key 2 moves along the upper surface of the slide block 4, and each lock pin 6 is pushed down to the lower surface of the card key 2 in the figure, so that the slide block 4 Settling in. At this time, the protrusion 63 of each lock pin 6 is moved from the upper end 51vu of the vertical groove 51v to the lower end 51vd of the vertical groove 51v beyond the horizontal groove 51h. At this time, the tip of the card key 2 is not in contact with the protruding piece 22 of the rotating member 20, and the rotating member 20 is not rotating. Thereafter, as shown in FIG. 17, the card key 2 is inserted until the tip of the card key 2 comes into contact with the abutting portion 44. In this state, the card key 2 has each key hole so that the positions in the In-Out direction (the insertion direction of the card key 2) and the width direction of the card key 2 (the Cs-Op direction) coincide with each lock pin 6. 2a is formed. For this reason, each lock pin 6 that has been settled is raised by the biasing force of the spring 68 to a position where the upper part of each tip portion 61 enters the corresponding key hole 2a. As described above, the dimension of the lock pin 6 and the dimension of the key hole 2a that correspond to each other have a dimension relationship in which the distal end portion 61 of the lock pin 6 stops without completely passing through the key hole 2a. In this state, the protrusions 63 of all the lock pins 6 are positioned at the height of the horizontal groove 51h. As a result, the locking action due to the fitting of the protrusion 63 and the vertical groove 51v is released, and the slide block 4 is slidable in the In direction with respect to the guide blocks 5A and 5B. Further, in the state where the tip of the card key 2 is in contact with the abutting portion 44, as described above, the rotating member 20 supported by the upper plate 8 rotates, and the unlocking restricting protruding portion 21 is displaced upward. is doing. Accordingly, the slide block 4 is slidable with respect to the rotating member 20.

When the card key 2 is further inserted in the In direction from the state shown in FIG. 17, the locked state of the locking mechanism C is released as shown in FIG. In FIG. 17, the slide block 4 is slidable. When the card key 2 is further pushed in the In direction, the tip of the card key 2 pushes against the abutting member 44 and each key hole 2a pushes each lock pin 6. Then, as shown in FIG. 18, the slide block 4, the lock pin 6, and the lock lever 7 are integrally slid against the spring 78 in the In direction. As a result, the slide block 4 slides in the In direction to take the unlock position, and the stopper 71 is retracted from the slide path of the shutter engaging portion 34. Thereby, the locked state of the locking mechanism C is released, and the shutter 3 is moved to the open position shown in FIG. 4 by the biasing force of the spring 38. In this way, by inserting the card key 2, the locking mechanism C can be unlocked and the umbrella receiving portion 11 can be opened.

In the present embodiment, with respect to the plurality of holes 41 formed in the slide block 4, as described above, when attention is paid to a set of one hole 41 selected from the rows 40 A and 40 B, each set is formed. The positional relationship of the holes 41 in the In-Out direction is different for each group. In this embodiment, the lock pin 6 is inserted into each hole 41 selected from the

rows

40A and 40B. For this reason, even if the card key 2 other than the dedicated key is inserted, the positions of the two lock pins 6 and the two key holes 2a do not coincide in the process of inserting the card key 2 in the In direction. Therefore, according to the umbrella holding | maintenance apparatus B, malfunctioning that it unlocks with the card keys 2 other than a dedicated key can be prevented.

Further, as described above with reference to FIG. 16, in the process in which the card key 2 is inserted into the insertion path 4E and moves in the In direction, before the tip of the card key 2 comes into contact with the abutting portion 44, The tip of the card key 2 is not in contact with the protruding piece 22 of the rotating member 20. That is, the protruding piece 22 remains in the insertion path 4 E of the card key 2, and the slide block 4 is prevented from moving backward in the In direction by the lock release restricting protrusion 21 of the rotating member 20. Therefore, according to the configuration including the rotating member 20 as described above, it is possible to prevent a malfunction such that the locked state of the locking mechanism C is released when the card key 2 is not inserted to the predetermined insertion state. be able to.

In FIG. 18, when the slide block 4 slides in the In direction to reach the unlocked position, the protruding portion 16a of the slide lock pin 16 appears higher than the lower surface of the slide block 4, and the slide block 4 is unlocked. It is impossible to slide in the Out direction from the position. On the other hand, the lock pin 6 is in a state in which a part of the tip portion 61 enters the key hole 2 a of the card key 2. Thus, when the shutter 3 is in the open position so that the umbrella receiving portion 11 is in the open state and the slide block 4 is in the unlocked position, the card key 2 cannot be pulled out via the lock pin 6. The FIG. 19 is a view similar to FIG. 10 when the shutter 3 is in the open position.

When the shutter 3 is slid to the closed position using the knob 32 from the state shown in FIGS. 18 and 19, the cam 34a of the shutter 3 and the cam 16c of the slide lock pin 16 come into sliding contact, and the slide lock pin 16 settles. (See FIG. 10). Then, the slide block 4 slides to the Out side by the biasing force of the spring 78, and the stopper 71 of the lock lever 7 is locked by the shutter locking portion 34. Again, the state of FIG. Become. In the moving process of the shutter 3, the bar 31 does not slidably contact the slide block 4, and the cam 34 a merely contacts the cam 16 c of the slide lock pin 16. Is suppressed from acting.

20 to 22 show a method of manufacturing the card key 2 using the card key manufacturing tool F shown in FIGS.

FIG. 20 shows a state in which the card body 2R before the key hole 2a is formed is inserted into the gap portion 204A of the card key making tool F. At this time, the card body 2R is positioned with respect to the card key preparation tool F by the pins 203, and the plurality of holes 201 of the large-diameter hole group 201A are a plurality of holes in which the key holes 2a can be formed in the card key 2. It overlaps with the opening position.

Next, as shown in FIGS. 20 and 21, among the plurality of holes 201, a hole 201 (hatched in FIG. 20 is marked with the same mark 202 as the mark 19 provided on the lower body 1 B of the umbrella holding device B). The puncher P is inserted. Next, as shown in FIG. 22, a part of the card body 2R is punched by pressing the puncher P downward. Here, the key hole 2a is formed in the punched portion of the card body 2R. Thus, the key hole 2a having the same diameter is formed in the card body 2R at the same position as the key hole 2a of the card key 2 shown in FIG. Next, a number corresponding to the number of the number display unit 17 of the body 1 is written on the number display unit 2b of the card body 2R as necessary. In this way, a new card key 2 is produced.

As described above, by using the card key manufacturing tool F of the present embodiment, even when the card key 2 is lost, the spare card key 2 can be quickly manufactured. Specifically, the plurality of holes 201 of the card key making tool F are in a positional relationship corresponding to the plurality of drilling positions set in the card key 2. If the positions of the holes 201 corresponding to the arrangement of the key holes 2a of the card keys 2 are managed with respect to the holes 201 of the card key preparation tool F, which one of the holes 201 is formed when a spare key is manufactured from the card body 2R. This is convenient because it can be seen whether or not the key hole 2a should be formed in this portion. If different marks 202 are provided corresponding to the holes 201 as in the present embodiment, management of the holes 201 corresponding to the drilling positions where the key holes 2a are to be formed becomes easy.

Furthermore, in this embodiment, the mark 19 provided on the back surface of the lower body 1B of the umbrella holding device B (the outer surface of the body 1) is a key hole 2a to be formed in the card key 2 dedicated to the umbrella holding device B. Shows the arrangement. Therefore, according to such a configuration, since the arrangement of the key holes 2a can be seen by looking at the mark 19 on the outer surface of the umbrella holding device B, it is not necessary to manage the arrangement of the key holes 2a, which is convenient.

23 to 25, the umbrella holding device B shown in FIG. 6 with the umbrella receiving portion 11 locked in the closed state is released using the master card key 2M, and the umbrella receiving portion 11 is opened. Shows how.

FIG. 23 shows the umbrella holding device B in a locked state, and is a plan view with the upper body 1A removed. The master card key 2M is different from the card key 2 in that a protrusion 2Ma is provided at the tip but no key hole is provided. As with the card key 2, the master card key 2M is inserted from the insertion port 12 in the In direction. The protrusions 2Ma are formed at both ends in the width direction of the master card key 2M, and are positioned to contact the lock release portion 72 when the master card key 2M is inserted in the In direction. Further, a portion other than the protruding portion 2Ma in the tip portion of the master card key 2M is recessed in the Out direction so as not to prevent the contact between the protruding portion 2Ma and the unlocking portion 72. As shown in FIG. 24, when the master card key 2M is inserted into the insertion path 4E, the protruding piece 22 of the rotating member 20 is pushed by the tip portion (the recessed portion) of the master card key 2M, and the rotating member 20 Rotate. Then, the pair of lock release restricting projections 21 are displaced upward, and the lock release unit 72 can be moved inward in the In direction. When the master card key 2M is further pushed in the In direction, the unlocking portion 72 is pushed in the In direction by the protrusion 2Ma. At this time, the slide block 4 is not pushed directly in the In direction by the master card key 2M.

As shown in FIG. 25, when the lock release portion 72 is pushed by the master card key 2M, the lock lever 7 is rotated clockwise in the figure against the spring 78 around the support pin 73. By this rotation, the horizontal portion 7A of the lock lever 7 assumes a left-up posture, and the stopper 71 is retracted diagonally upward to the right in the drawing from the slide path of the shutter engaging portion 34. Thereby, the locked state of the locking mechanism C is released, and the shutter 3 is returned to the open position. 24 and 25, the unlocking of the locking mechanism C by the master card key 2M is achieved only by the rotation of the lock lever 7. At this time, the slide block 4 is locked toward the Out direction. It remains in position. In this way, the card key 2 and the master card key 2M are released by different mechanisms.

In the present embodiment, when the card key 2 is lost, it is possible to produce a spare card key 2 using the card key making tool F as described above. The umbrella holding device B can be unlocked by 2M.

In the present embodiment, the lock release units 72 are located at both ends of the card key 2 in the width direction. On the other hand, the protruding piece 22 of the rotating member 20 is located at the center of the card key 2 in the width direction, and is different from the unlocking portion 72 in the width direction of the card key 2. For this reason, for example, even if a plate-like body narrow enough to poke the lock release portion 72 is inserted into the insertion path 4E and the lock release portion 72 can be poke, the protruding piece of the rotating member 20 22 cannot be retracted from the insertion path 4E. Therefore, the unlocking portion 72 is in a state in which the movement toward the back in the In direction is prevented by the unlocking restricting projection 21 of the rotating member 20. As a result, the lock lever 7 does not rotate and the locking state of the locking mechanism C is not unreasonably released. As can be understood from the above, according to the configuration including the rotating member 20, the problem that the umbrella holding device B is unlocked due to malfunction due to something other than the authentic master card key 2 M is prevented. can do.

It should be noted that the shape of the master card key 2M and the arrangement of the lock pins 6 are irrelevant in releasing the lock state of the locking mechanism C by the master card key 2M. Therefore, even when the number of umbrella holding devices B that can be used at the same time is increased, it can be covered with one type of master card key 2M, which is convenient.

26 and 27 show another configuration example of the umbrella holding device to which the locking device of the present invention is applied. In the umbrella holding device B shown in FIGS. 26 and 27, the configurations of the guide blocks 5A and 5B are different from those of the above embodiment. In FIG. 26 and FIG. 27, the same or similar elements as those of the above embodiment are denoted by the same reference numerals as those of the above embodiment, and description thereof will be omitted as appropriate.

In the guide blocks 5A and 5B of the present embodiment, the formation position of the horizontal groove 51h is below the guide blocks 5A and 5B (see FIG. 7) in the locking mechanism C described above. In the card key 2 corresponding to the umbrella holding device B of the present embodiment, the diameter of the key hole 2a is smaller than that shown in FIGS. As shown in FIG. 27, when the card key 2 is inserted into the insertion path 4E until the position of the key hole 2a coincides with the lock pin 6, the tip portion 61 of the lock pin 6 rises so as to enter the key hole 2a. Since the key hole 2a has a small diameter, the lock pin 6 stops below the case shown in FIG. In this state, the protrusion 63 of the lock pin 6 is positioned at the height of the horizontal groove 51h, and the slide block 4 can slide in the In direction with respect to the guide blocks 5A and 5B. That is, by preparing the card key 2 having the key holes 2a having different diameter sizes, the height position of the lock pin 6 when the card key 2 is in a predetermined insertion state can be varied. Thus, if the formation position of the horizontal groove 51h of the guide blocks 5A and 5B is changed, and the diameter size of the key hole 2a of the card key 2 is changed correspondingly, the same lock pin 6 is used, and Even if the arrangement of the lock pins 6 is the same, two or more combinations can be provided. For example, in the slide block 4 shown in FIG. 6, when the lock pins 6 are inserted into the respective holes 41 selected from the respective rows 40 A and 40 B, the lock pins 6 can be arranged in 16 combinations. is there. Furthermore, when two types of

guide blocks

5A and 5B are prepared as described above, there are four combinations of the guide blocks 5A and 5B. In this case, the 64 umbrella holding devices B can be unlocked by the dedicated card key 2 respectively. Such a configuration is suitable for increasing the number of umbrella holding devices B that can be used simultaneously.

If the card key preparation tool F described above is used, the key hole 2a of the card key 2 shown in FIG. 27 can be manufactured. 28 to 30 show a method for producing the card key 2 in which the key hole 2a having a small diameter size is formed by using the card key producing tool F shown in FIGS.

FIG. 28 shows a state in which the card body 2R before the key hole 2a is formed is inserted into the gap portion 204B of the card key making tool F. At this time, the card body 2R is positioned with respect to the card key preparation tool F by the pins 203, and the plurality of holes 201 of the small diameter hole group 201B are formed with a plurality of holes in which the key holes 2a can be formed in the card key 2. It overlaps with the position. In the case of the card key 2 in which the small-diameter key hole 2a is formed, for example, a lowercase alphabet is used as the mark 19 of the umbrella holding device B. When the arrangement of the lock pins 6 of the umbrella holding device B is in the state shown in FIG. 6, the mark 19 is expressed as “az”.

Next, as shown in FIGS. 28 and 29, among the plurality of holes 201 constituting the small-diameter hole group 201B, the same mark 202 as the mark 19 provided on the lower body 1B of the umbrella holding device B is given. The puncher P is inserted into the hole 201 (hatched in FIG. 28). Here, as the puncher P, a puncher P whose outer diameter is made small corresponding to the diameter of the lower hole 221b of the lower block 220 is used. Next, as shown in FIG. 30, a part of the card body 2R is punched by pressing the puncher P downward. Here, a key hole 2a having a small diameter is formed in the punched portion of the card body 2R. Thus, the key hole 2a having the same diameter is formed in the card body 2R at the same position as the key hole 2a of the card key 2 shown in FIG. Next, a number corresponding to the number of the number display unit 17 of the body 1 is written on the number display unit 2b of the card body 2R as necessary. In this way, a new card key 2 is produced.

The specific embodiments of the present invention have been described above, but the locking device and the card key manufacturing tool according to the present invention are not limited to the above-described embodiments. The specific configuration of each part of the locking device and the card key manufacturing tool according to the present invention can be varied in design in various ways.

In the above embodiment, the case where the key hole 2a formed in the card key 2 is circular has been described as an example, but the key hole of the card key may have other shapes such as a triangle or a quadrangle. For example, when a plurality of types of quadrangular key holes of different sizes are formed on a card key, the card key making tool has a plurality of quadrangular holes of different sizes corresponding to the key holes of the card key. What is necessary is just to comprise the group which consists of holes. Further, the key hole of the card key may be constituted by a plurality of types of irregular shapes. “Different sizes” in the key hole of the card key means that when the card key is inserted into the locking device, the sharp tip of the lock pin enters the key hole of the card key and the tip is the key hole. This means that the amount of displacement of the lock pin until it is regulated by coming into contact with the periphery of the key differs for each type of key hole. And as a variation that constitutes a plurality of types of key holes of different sizes, there are a plurality of types of key holes having the same shape and different peripheral sizes as in the above embodiment, and a plurality of types of different shapes and different peripheral sizes. There are cases where the key hole is formed.

In the above-described embodiment, the case where the mark 19 indicating the arrangement of the key hole 2a to be formed in the card key 2 is provided on the outer surface of the body 1 has been described as an example. . In the case where the body 19 is not provided with the mark 19, for example, the card key 2 is appropriately manufactured by managing a list describing the arrangement of the key holes 2a corresponding to the numbers displayed on the number display portion 17 of the body 1. Is possible.

As a card key or master card key used for releasing the lock state of the locking device, a dummy key hole may be additionally provided at a position unrelated to the position of the hole of the slide block.
