Description

TECHNICAL FIELD The present invention relates to a latch used together with a padlock when locking an article by restricting the movement of an article, and a car stop fence post provided with the latch as a locking means .

  As a stop rail pillar installed at the entrance of a parking lot, a park, a private road, etc., the one shown in FIG. 6 has been widely used. The illustrated vehicle stop fence post 1 is composed of a storage pipe 2 buried in the ground and an inner pole 3 inserted into the storage pipe 2 so as to be able to move in and out. The inner pole 3 is placed in the storage pipe 2 when not in use. The inner pole 3 is lifted to the ground when it is buried and the entry of the vehicle is stopped. A lid 4 is pivotally attached to the upper edge of the opening of the storage pipe 2 so as to be openable and closable. In addition, through holes 31 and 32 are formed in the lower portion of the inner pole 3 so as to communicate with the through holes and allow the headed fixing pin 5 to be inserted therethrough. The fixed pin 5 with the head is inserted into the through holes 41, 31, and 32, and the lock rod 61 of the padlock 6 is hooked in the locking hole 51 formed at the tip of the pin 5. As a result, the fixed pin 5 with the head is prevented from coming off while penetrating the inner pole 3, and the inner pole 3 is restrained from falling into the storage pipe 2 and locked so that the inner pole 3 is not stolen.

In addition to the above, as a similar technique for similarly locking this kind of car retaining fence pillar using a padlock, those described in Patent Documents 1 to 3 are known.

  In the example shown in FIG. 6, it is necessary to insert the head fixing pin 5 into the inner pole 3, so that the operation is somewhat troublesome, and the inner pole 3 has through holes 31 and 32 penetrating both sides on both sides. It is necessary to form on the surface. Further, in the examples described in Patent Documents 1 to 3, although each has advantages and disadvantages, the configuration of parts is complicated and it takes time to assemble, and the manufacturing cost is increased.

The present invention provides a padlock latch that can be more easily locked at a low cost and can be manufactured at a low cost by a configuration different from the above-described conventional technology, and a vehicle stop fence provided with the latch as a locking means. It was made to provide pillars . However, the latch for the padlock according to the present invention is not limited to the locking of the above-mentioned lock rail post, but restricts the movement of various articles or connects two or more articles. Thus, it can be widely used in general applications that do not move each other.

The latch for the padlock of the present invention is inserted into a locking through hole formed on one surface of the article to be restrained in movement, and the latch is pulled out from the through hole by latching the padlock in the inserted state. In this way, the movement of the article is restricted. The basic configuration of the latch, a pair of engaging pieces bent in opposite directions to each other in the longitudinal direction substantially intermediate portion, are mutually rotatably journaled via a shaft member in the intermediate portion near each the rear end of the lock part becomes locked hole is formed respectively, while the rear end side of the respective hooking pieces and polymerizing the tip side ends of each hooking piece that Hiroga the substantially V-shaped and polymerizing the rear side ends of the respective hooking pieces meet the above two locking holes, as the tip width I tip side each other Hiroga substantially V-shape is wider than the intermediate portion In addition, the rear end side of each of the latching pieces is formed with protrusions that protrude in opposite directions when the rear end sides of the respective latching pieces are overlapped with each other. .

Further, the stop rail post of the present invention includes a storage pipe embedded in the ground, an inner pole inserted in and out of the storage pipe, and a lock for restraining the inner pole in a state where the inner pole is pulled up to the ground. The locking means column includes a through hole formed on one side of the lower side of the inner pole, a latch inserted into the through hole, and latched on the latch. The latch has a pair of latching pieces bent in opposite directions in a substantially middle part in the length direction, and is pivotally attached to each other via a shaft member in the vicinity of the middle part. A locking hole is formed on the rear end side of each latching piece, and when the leading end sides of the respective latching pieces are polymerized, the rear end sides of the respective latching pieces expand in a substantially V shape, When the rear end sides of the respective latching pieces are polymerized, the both locking holes are matched, The sides are widened in a substantially V shape so that the tip width is wider than the intermediate portion, and the rear end sides of the respective latching pieces are arranged on the rear end sides of the respective latching pieces. Protrusions that protrude in opposite directions are formed, and the leading ends of the latching pieces are aligned with each other and inserted into the through hole of the inner pole, and the latching pieces rotate with respect to each other. The rear end sides are aligned and overlapped, and when the padlock of the padlock is locked at the place where the locking holes of the both locking pieces are matched, the front end side of the locking piece expands and cannot be pulled out from the through hole. The protruding portion of the latching piece overhangs and the immersion into the through hole is prevented.

  The latch of the present invention is inserted into the through hole for locking formed on one side of the article whose movement is to be restrained in a state where the front end sides of the latching pieces are overlapped with each other, and after the insertion, the rear end side of the latching piece When the padlocks are hooked onto the matching locking holes by polymerizing each other, the leading end side of the hooking piece expands in a substantially V shape and cannot be removed from the through hole. Using this, it is possible to lock the movement of an article in a movable state or to lock two or more articles in a connected state.

  Although such a latch has a simple structure and can be manufactured at a low cost, it has excellent usability and a reliable locking effect. Further, if such a latch is used, the locking through hole formed on the article side is economical because only one place on the side where the latch is inserted is required, and its application is expanded.

  Hereinafter, embodiments of the present invention will be described by taking as an example the case of fixing an inner pole of a car retaining fence post.

  1 and 2 basically has a storage pipe (not shown) embedded in the ground, and is freely inserted and retracted into the storage pipe in the same manner as that shown in FIG. The inner pole 30 is embedded in the storage pipe when not in use, and the inner pole 30 is lifted to the ground when stopping the vehicle from entering. A lid 40 is pivotally attached to the upper edge of the opening of the storage pipe so as to be openable and closable. A through hole 41 for inserting the latch of the present invention is formed in the lid 40. A through hole 31 that communicates with the through hole 41 of the lid 40 is also formed in the lower portion of the inner pole 30. However, in the present invention, the through-hole 31 formed in the inner pole 30 is sufficient at one place on one side.

  Then, with the inner pole 30 pulled up, the latch 7 of the present invention is inserted into the through hole 41 of the lid 40 and the through hole 31 of the inner pole 30, and the lock rod 61 of the padlock 6 is latched on the latch 7. . As a result, the latch 7 cannot be removed while being inserted into the through holes 41 and 31, and the inner pole 30 is restrained from falling and locked so that the inner pole 30 is not stolen.

  As shown in FIGS. 3 to 4, the latch 7 has two metal latching pieces 71a and 71b made of steel plates and the like, and an intermediate portion thereof is pivoted by a shaft member 72 such as a caulking pin. It is what I wore. One latching piece 71a has a front end side 73 and a rear end side 74 extending in a substantially rectangular shape with a shaft attachment portion as a boundary, and the long axis of the rectangle is bent in a substantially “h” shape. On the rear end side 74, a locking hole 75 for hooking the padlock 6 is formed. In addition, a substantially triangular protrusion 76 that protrudes toward the peak side of the “H” character is formed at an intermediate portion on the rear end side 74.

  The other hooking piece 71b has the same shape as the one hooking piece 71a, and the one hooking piece 71a is in a posture in which the hooking piece 71a is turned upside down, that is, in an inverted “h” shape. And is attached.

  In the locking operation, first, as shown in FIG. 3, the distal end side 73 is inserted into the through holes 41, 31 of the lid 40 and the inner pole 30 with the distal end sides 73 of the latching pieces 71a, 71b aligned and overlapped. To do. Naturally, the width of the distal end side 73 is set to be slightly smaller than the width of the through holes 41 and 31. When the front end sides 73 of the latching pieces 71a and 71b are aligned, the rear end sides 74 of the latching pieces 71a and 71b expand in a substantially V shape.

  If the front end side 73 of the latching pieces 71a and 71b is inserted into the through holes 41 and 31, as shown in FIG. 4, the latching pieces 71a and 71b are rotated as they are, and the rear end sides 74 And align. Then, the locking holes 75 of both the latching pieces 71a and 71b are matched, and the distal end side 73 expands in a substantially V shape. The maximum width of the expanded distal end side 73 is set to be larger than the width of the through holes 41 and 31. If the paddle 61 of the padlock 6 is hooked in the locking hole 75 in this state, the latch 7 cannot be pulled out from the through holes 41 and 31. At this time, the protrusions 76 of the latching pieces 71a and 71b also project in the vertical direction in the figure, so that the latch 7 is prevented from entering the through holes 41 and 31. Thus, the inner pole 30 and the lid 40 can be connected and locked with the latch 7 and the padlock 6 by a very simple operation.

  In the unlocking operation, it is only necessary to unlock the padlock 6 and remove the lock rod 61 from the locking hole 75 and to remove the latch 7 from the through holes 41 and 31, so that no special operation is required. The removed latch 7 is convenient because it can be prevented from being lost if the paddle 61 of the padlock 6 is inserted and stored together with the padlock 6.

  It should be noted that the raised inner pole 30 does not necessarily have to be connected to the lid 40 in a car retaining fence post having a structure in which the inner pole 30 does not come out of the storage pipe. In this case, as shown in FIG. 5, the latch 7 is inserted only into the through hole 31 formed in the inner pole 30 and locked with the padlock 6. Then, even if the inner pole 30 tries to descend due to its own weight, the latch 7 and the padlock 6 protruding to the side come into contact with the upper end edge 21 of the opening of the storage pipe or in the vicinity thereof to prevent the inner pole 30 from being lowered further. Disappear. Thus, the latch 7 of the present invention can be used not only for a plurality of articles but also for a single article.

  The latch for the padlock according to the present invention is not limited to the illustrated stop rail pillar, but includes, for example, simple locking means for joinery, locking means such as lids of various containers, lockers, doors of display cases, or articles that prohibit movement. The present invention can be widely used in general applications in which one or two or more connected articles such as restraining means are locked so as not to move with a padlock. Of course, depending on the shape of the locking through-hole formed in the article, the dimension and shape of the latching piece, the “bent” -shaped bending angle, the protruding dimension of the protrusion, and the like may be adjusted as appropriate.

It is a perspective view which shows embodiment (state before locking) of this invention. Similarly, it is a perspective view showing an embodiment (state after locking) of the present invention. It is a figure which shows the shape and effect | action (state before locking) of the latch of this invention.
