In other words, the locking is performed in a state where the vine portion 21 is engaged with the distal end portion 33 of the key member 3. Further, the main body portion 22 is provided with an insertion hole 22a into which the tip 21a of the hanging portion 21 is inserted when the padlock 2 is locked. The padlock 2 does not have to be a key type locking method, and may be a dial type.

  The padlock cover 1 is made of hard metal and has a wall 10 that forms an internal space 15 that opens downward. The internal space 15 is a space for accommodating the vine portion 21 of the padlock 2 in the locked state and the vine portion side portion of the main body portion 22.

  Examples of the hard metal include stainless steel and iron, and the wall 10 is a welded structure made of a plate material having a thickness of about 2 to 3 mm made of these hard metals.

  The size of the wall 10 is set to such an extent that the vine portion 21 does not protrude outside the internal space 15 no matter how the posture of the key member 3 and the engagement posture of the padlock 2 with respect to the key member 3 change. Has been.

  Specifically, as shown in FIG. 2, the wall 10 includes a cylindrical peripheral wall 11 that surrounds the internal space 15, and a bottom wall 12 that closes one of the openings formed by the peripheral wall 11. Yes. The padlock 2 can be inserted into the internal space 15 from the opening 14 that is not closed by the bottom wall 12 formed by the peripheral wall 11.

  The peripheral wall 11 has a rectangular frame-shaped cross-sectional shape, and the bottom wall 12 has a rectangular plate shape orthogonal to the extending direction of the peripheral wall 11. The distance between the pair of short wall portions 11a and 11b facing each other in the longitudinal direction of the peripheral wall 11 is set sufficiently larger than the width of the main body portion 22 of the padlock 2, while the pair of long walls facing each other in the short direction. The distance between the portions 11 c is set slightly larger than the thickness of the main body portion 22 of the padlock 2. For this reason, when the main body portion 22 is inserted into the internal space 15, the main body portion 22 cannot rotate around a line parallel to the extending direction of the peripheral wall 11. In other words, the peripheral wall 11 is formed in such a shape that when the main body portion 22 is inserted into the internal space 15, the main body portion 22 is fitted so as not to rotate.

  The right short wall portion 11a of the pair of short wall portions 11a and 11b is provided with an insertion port 13 for inserting the distal end portion 33 of the key member 3 at a position slightly above the center in the vertical direction. ing. The dimension in the front-rear direction of the insertion port 13 is set to be slightly larger than the width (dimension in the front-rear direction) of the distal end portion 33, but the vertical dimension is slightly smaller than the thickness of the distal end portion 33. It is set large. For this reason, the front-end | tip part 33 can be inserted in the insertion port 13 from diagonally upward (refer FIG. 3).

  Further, the peripheral wall 11 and the bottom wall 12 are in a state in which the vine portion 21 of the padlock 2 is inserted into the engagement hole 34 of the key member 3 in the internal space 15 and the tip 21 a is inserted into the main body portion 22. In the state, as shown in FIG. 4, if the padlock cover 1 and the padlock 2 are tilted with respect to the key member 3, the body portion 22 of the padlock 2 can be positioned outside the internal space 15, and the body portion 22 is When pushing into the internal space 15, the tip 21 a can be inserted into the main body portion 22 by the vine portion 21 being pressed against the bottom wall 12.

After the vine portion 21 is inserted into the engagement hole 34 of the key member 3, the main body portion 22 can be rotated with respect to the vine portion 21 so that the tip 21a of the vine portion 21 can be inserted. In addition, the peripheral wall 11 and the bottom wall 12 can be inserted into the main body portion 22 by pushing the vine portion 21 against the bottom wall 12 when the main body portion 22 is pushed into the internal space 15. Therefore, it is possible to obtain a reaction force when inserting the tip 21a of the hanging portion 21 with the bottom wall 12.

  Next, a procedure for engaging the padlock 2 with the key member 3 will be described.

  First, as shown in FIG. 3, in a state where the main body portion 22 of the padlock 2 is connected to the portion 21 by a 180 ° line from a normal position (a position where the tip 21a of the portion 21 can be inserted into the insertion hole 22a). The padlock 2 is set in the internal space 15 of the padlock cover 1. At this time, the tip 21 a of the vine portion 21 is positioned above the insertion opening 13.

  Then, the distal end portion 33 of the key member 3 is inserted into the internal space 15 from the insertion opening 13, and then the tip 21 a of the vine portion 21 is tilted so as to rotate clockwise in FIG. Insert into the joint hole 34.

  Next, as shown in FIG. 4, the padlock 2 and the padlock cover 1 are brought into a posture in which the main body portion 22 of the padlock 2 is located outside the internal space 15, and the main body portion 22 is rotated with respect to the hanging portion 21 to the normal position. Thereafter, the main body portion 22 is pushed into the internal space 15 so that the tip 21a of the vine portion 21 is inserted into the insertion hole 22a and locked.

  In the padlock cover 1 of the present embodiment, since the vine portion 21 of the padlock 2 is accommodated in the internal space 15 formed by the wall 10, the vine portion 21 is cut with a tool such as a nipper. Can be prevented. In addition, since the wall 10 is provided with the insertion port 13 for inserting the distal end portion 33 of the key member 3, the distal end portion 33 is inserted into the inner space 15 from the insertion port 13, and the key is inserted into the inner space 15. When the padlock 2 is engaged with the member 3, the extraction of the key member 3 from the insertion port 13 is prevented by the padlock 2. That is, the cover can be prevented from being removed with a simple configuration in which the insertion opening 13 is simply provided in the wall 10.

  Moreover, in this embodiment, since the surrounding wall 11 is formed in the shape which the said main body part 22 fits non-rotatably when the main body part 22 of the padlock 2 is inserted in the internal space 15, in the surrounding wall 11, The constructed opening 14 is sufficiently closed by the body portion 22 of the padlock 2. Therefore, it is possible to prevent the tool 21 from being inserted through the opening 14 and cutting the vine portion 21 of the padlock 2.

  In addition, in the said embodiment, as shown to Fig.5 (a), you may make it provide the slit 16 which can insert the vine part 21 of the padlock 2 in the short wall part 11b of the left side of the surrounding wall 11. FIG. In this way, when the padlock 2 is engaged with the key member 3, the tip 33 of the key member 3 is inserted into the insertion opening 13 without the padlock 2 being set in the internal space 15 in advance. Later, the padlock 2 can be inserted into the internal space.

  Further, as shown in FIG. 5B, the left short wall portion 11b may be omitted. However, in this case, the condition is that the size of the wall 10 is set so that the portion 21 that is obtained by rotating the padlock 2 clockwise in FIG. 1 stays in the internal space 15.

  Furthermore, the wall 10 does not need to be a welded structure and may be a casting. In this case, as shown in FIG. 6, the bottom wall 12 can be formed in a curved shape so as to protrude upward.

  Furthermore, the cross-sectional shape of the peripheral wall 11 does not have to be a rectangular frame shape, and may be, for example, an elliptical frame shape.

  Further, it is sufficient that at least the vine portion 21 of the padlock 2 is accommodated in the internal space 15 of the padlock cover 1, and the size of the wall 10 is accommodated only by the vine portion 21 in the internal space 15. It may be set to such an extent that the entire body portion 22 is accommodated in addition to the hanging portion 21 in the internal space 15.

  Further, the position where the insertion port 13 is provided is not limited to the short wall portion 11a, but can be provided on the long wall portion 11c or the bottom wall 12.

  Further, the present invention can be widely applied to a structure using a padlock (for example, a gate door) other than the car stopper, and the object to be engaged may not be the key member 3.
