JP5042733B2 - A padlock with a cutting prevention device and a ground-mounted pole device using this padlock - Google Patents

Description

  The present invention relates to a padlock provided with a cutting prevention device and a ground-mounted pole device using the padlock.

  Recently, theft of detachable metal poles established on the ground, such as car stops, has occurred.

  Therefore, measures are taken such as connecting the pole and the foundation side fixed on the ground with a chain, locking the chain with a padlock, and preventing the pole from being pulled out unless it is unlocked.

  If the padlock is locked, the padlock's U-shaped lock rod is relatively thin, so it can be easily cut using a simple tool such as a gold saw or clipper, and unlocked and the pole is pulled out. It is hard to avoid being taken away.

  If the U-shaped lock padlock of the padlock is made thick and difficult to cut, the padlock will become large and expensive, and it will be necessary to increase the hole diameter for the lock to pass through the lock pad, which also makes the lock pin itself thick As a result, there is a problem that related constituent members are also enlarged.

The above problem is not limited to theft of the pole, but there is a similar problem in the locking of facilities, fence doors, and the like.

  The present invention prevents the blade of the tool from entering even when trying to cut the U-shaped lock rod of the padlock using a tool such as a clipper or a gold saw, making the cutting operation impossible, preventing the intrusion into the facility or fence, and theft of the pole The challenge is to ensure that prevention is achieved.

  As means for solving the above-mentioned problems, the present invention provides a guard member provided with a jetty that can be fitted as close as possible to the inside of a U-shaped lock rod of a padlock, and can cover substantially the entire side surface of the lock rod when locked. It is characterized by including the cutting prevention device which has these.

  It is preferable to form a recess into which the lock part on the lock object side to be locked is inserted through the U-shaped lock rod of the padlock in the upper end position of the jetty or in the vicinity thereof.

  In addition, it is desirable to provide a bottom portion of the jetty so as to be fitted so as to straddle both sides of the upper end of the locked padlock body in order to enhance the cutting prevention effect.

  On the other hand, the padlock is suitable for application to anti-theft locking of other metal objects such as a detachable vehicle stop pole, a passage section arch pole, and other poles established on the ground.

  According to the present invention, even if the U-shaped lock rod of the padlock in the locked state is to be cut using a tool such as a gold saw or clipper, the substantially entire side surface of the U-shaped lock rod is completely hidden by the jetty of the guard member. Therefore, the blade of a tool such as a gold saw or clipper cannot be applied to the U-shaped lock rod, and it is possible to completely prevent the U-shaped lock rod from being cut and unlocked.

  If a bottom part straddling both sides of the upper end of the padlock body is provided at the lower end of the jetty, the entire U-shaped lock rod can be covered, and the cutting prevention effect can be further enhanced.

  Even if the padlock is destroyed, it takes a long time, so the unlocking can be abandoned, and these can improve safety.

  Therefore, it can function extremely effectively when applied to a lock for preventing theft of a ground-mounted pole installed outdoors.

  FIG. 1 shows a state where a lock portion 2a of a gate 2 as an example of a lock is locked by a padlock 1 equipped with a cutting prevention device according to the present invention, and FIG. 2 (A) shows a padlock 1 in that state as shown in FIG. B) shows a state where the key 3 is unlocked.

  The cutting preventing device according to the present invention is configured by combining a guard member 5 with a padlock 1 having a U-shaped lock rod 4.

  As shown in FIGS. 3A to 3C, the guard member 5 can be fitted as tightly as possible inside the U-shaped lock rod 4 inserted through the lock hole of the lock portion 2a. , 6 and 6 are formed so as to conceal substantially the entire side surface of the lock rod 4, and recesses 7 and 7 into which the lock portion 2 a can be fitted are formed at the center of the upper ends of the ridges 6 and 6. .

  At the lower end of the guard member 5, hem portions 8, 8 are fitted so as to straddle both sides of the upper end of the locked padlock body 1 a, and are fitted to the padlock body 1 a of the U-shaped lock rod 4. It is designed to completely hide the root part.

  4 (A) to 4 (E) show the process of setting the guard member 5 to the padlock 1. The U-shaped lock bar 4 of the padlock 1 is inserted into the lock hole of the lock portion 2a to be locked and then the guard. After inserting the member 5 in a sideways position into the U-shaped lock rod 4 in the direction of the arrow A (FIG. 4A), the U-shaped lock rod 4 is positioned between the jetty 6 and 6 and fitted. When the guard member 5 is rotated 90 degrees in the direction of arrow B in FIG. 4 (A) and the lock portion 2a is pushed in the direction C in FIG. 4 (C) to fit into the recesses 7 and 7, FIG. The padlock body 1a is relatively rotated in the direction of arrow D in FIG. 4D in this state, and the lock portion 2a is inserted into the recesses 7 and 7 as shown in FIG. After that, the lock hole 1b of the padlock body 1a is aligned with the U-shaped lock rod 4 position. If not tucked a U-shaped lock lever 4 in the direction of arrow E, FIG. 1, FIG. 2 (A), the a locked state as shown in Figure 4 (D).

  As a result, the U-shaped lock rod 4 is completely buried between the jetties 6 and 6 of the guard member 5, and the blade cannot be applied to the U-shaped lock rod 4 even if it attempts to cut with a gold saw or clipper blade. It can be surely prevented from being cut.

  When unlocking, after unlocking with the key 3, the guard member 5 can be removed by the reverse procedure of the above-mentioned operation, and the padlock 1 is removed by removing the U-shaped lock rod 4 from the lock hole of the lock portion 2a. be able to.

  In addition, although the example which locks the lock | rock part 2a of the inner door 2 directly was shown in the above-mentioned description, this invention is not limited to this. For example, the guard member 5 is used even when a loop is formed using a chain so as to tie an object that is desired to avoid theft to a house or the like, and a padlock is applied between the loop-shaped chain unit elements so that the loop is not released. Can do. In this case, the chain unit element on which the U-shaped lock rod 4 is bridged forms a lock portion that fits into the recess 7.

  FIG. 5 shows an embodiment of a ground-mounted pole device using a padlock according to the present invention. The metal is erected by inserting a lower end into a support hole 10 excavated from the ground surface and reinforced by a sheath tube 9. A pole 11 made of metal, and a cap 14 that is pivotally supported by a pin 13 on a bearing portion 12 fixed on the ground surface so that it can be raised and lowered. The cap 14 is crowned and closed on the upper end opening of the support hole 10 after the pole 11 is pulled out. The cap 14 has a through hole formed in the cap 14 so as to be prevented from being removed by a large-diameter head 15a, and is inserted into a lock pin insertion hole 11a formed in the diameter direction of the pole 11 so as to be freely inserted. And a lock pin 15 having a lock hole 15c for locking.

  FIGS. 6A to 6C show a procedure for establishing and locking the pole 11 of the above-ground-type pole device. The cap 14 that has closed the open end of the support hole 10 is raised to raise the pole 11. Is inserted into the support hole 10, the lock pin 15 is passed through the through hole of the cap 14, and then passed through the lock pin insertion hole 11a of the pole 11 (FIG. 6 (A) → (B)).

  The U-shaped lock rod 4 of the padlock 1 is inserted into the lock hole 15c of the lock portion 15b of the lock pin 15 projecting from the opposite side of the pole 11, and the guard member 5 is fitted by the above-described procedure to attach the U-shaped lock rod 4 When closed, the pole 11 can be unlocked and locked (FIG. 6C).

  When it is necessary to pull out the pole 11, the padlock 1 is unlocked and removed from the lock pin 15 as described above. Then, if the lock pin 15 is pulled out from the pole 11, the restraint of the pole 11 is released and pulled out upward. Can do.

  After pulling out the pole 11, if the cap 14 is laid down, the opening of the support hole 10 is closed, and intrusion of dust and rainwater is prevented.
