The present invention relates to a depth adjusting device used for a duplicate key duplicating machine capable of duplicating a plurality of duplicate keys particularly with high accuracy.

A conventional duplicating machine mainly includes a main body, a pin, a cutter, and two holding tools that move synchronously with the main body. When duplicating a duplicating key, the master key is held and fixed to one of the holding tools. At the same time, the child key is clamped and fixed to the other holding tool, and the child key is cut by the cutter based on the shape of the key part of the parent key so that the pin comes into contact with the key part of the parent key. Duplicate in the same way as the key part of the key.

However, in a conventional duplicating machine, an error often occurs between the parent key and the child key. This is a problem of the duplicating machine itself or an artificial problem by a key operator who operates the machine. In addition, when duplicating the key, the child key is cut while the pin is in contact with the key portion of the parent key, so that the key portion of the parent key may be worn out or damaged.

Therefore, when a grandchild key is duplicated from the duplicated child key, the error may be further increased, and when a large number of keys are to be duplicated, the duplicate key is duplicated from the error key. As a result, there is a possibility that a considerable error occurs from the first master key and the unlocking cannot be performed.

According to the present invention, there is provided a depth adjusting device for a key, wherein a recess is formed on an upper surface, a spring and a ball are accommodated in the recess, and a part of the ball protrudes from an opening of the recess by the spring; A plurality of adjustment holes with different depths are formed on the outer peripheral surface, and a plurality of positioning grooves that are engaged with the balls so as to correspond to each other are formed on the periphery of the bottom surface at intervals.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.

As shown in FIGS. 1 to 3, the depth adjusting device used in the key duplicating machine according to the present invention has a base 10 and an adjusting plate 20, and the base 10 is an elongated rectangular plate. A circular recess 11 is formed in the upper surface near one end, a through hole 12 is formed in the center of the circular recess 11, and a positioning member is installed on the upper surface of the corner of one end. A concave portion (not shown) is formed on the upper surface of the concave portion, a narrow opening is formed in the upper portion of the concave portion, and a spring and a ball 13 (not shown) are provided inside the concave portion, and the spring contacts the ball 13. A part of the ball 13 is projected from the opening of the recess by the biasing force of the spring.

The adjustment plate 20 is rotatably attached to the circular recess 11 of the base 10, and has a cylinder 21, an upper ring 22 that is provided around the upper part of the cylinder 21, and a lower stage that is provided around the lower part of the cylinder 21. A plurality of adjustment holes 211 having different depths are formed on the outer peripheral surface of the middle stage of the cylinder 21, and a cap 212 is protruded at the upper end, and is sandwiched between the outer peripheral surfaces of the cap 212. A tool handle 213 extends in the radial direction, a bottom disk 214 corresponding to the circular recess 11 protrudes from the lower end, a screw hole 215 corresponding to the through hole 12 is formed on the bottom surface of the bottom disk 214, and a bolt 216 passes through the through hole 12 and is screwed into the screw hole 215.

The upper stage ring 22 is provided with a plurality of reference numerals 221 corresponding to the cylindrical holes 211 with a numerical value of the depth of the adjustment hole 211 at the periphery of the upper surface thereof at predetermined intervals. A plurality of positioning grooves 231 are formed at predetermined intervals, and the intervals between the positioning grooves 231 are the same as the intervals between the reference numerals 221.

As shown in FIG. 3, according to this configuration, when the adjustment plate 20 is attached to the base 10, if any one of the adjustment holes 211 is positioned coaxially with the longitudinal direction L of the base 10, 13 are engaged with the corresponding positioning grooves 231, and the adjustment plate 20 is positioned to be in a non-rotating state with respect to the base 10.

In the present embodiment, the adjustment plate 20 is provided with five adjustment holes 211 and five reference numerals 221, which are respectively 0, 1, 2, 3, 4 in order of decreasing depth of the adjustment holes 211. The greater the number, the deeper the corresponding adjustment hole 211 is located.

As shown in FIGS. 4 to 6, when using the depth adjusting device used in the key duplicating machine according to the present invention, first, the base 10 is movable so as to oppose the adjusting plate 20 in the base 10. It is installed in a key duplicating machine 30 including a key clamping tool 31 attached to the end, a pin 32 installed in the vicinity of the adjustment plate 20, and a cutter 33 installed in the vicinity of the key clamping tool 31.

First, before creating a joint key, the notch portion of the master key is compared with the adjustment hole 211 of the adjustment plate 20 in advance, and the depth of each corresponding notch portion is memorized as a numerical value 221. Thereafter, the child key 40 is clamped and fixed by the key clamping tool 31, and the base 10 is moved in a predetermined direction (the arrow direction in FIG. 5) so that the cutting position of the child key 40 corresponds to the cutter 33. The adjustment plate 20 is rotated, and the corresponding adjustment hole 211 is selected by aligning the numerical value 221 that has been memorized in advance with the pin 32.

According to the above-described configuration, when the adjustment plate 20 is rotated and the adjustment hole 211 is selected and set, the ball 13 escapes from the positioning groove 231 and engages with the other positioning groove 231. The plate 20 can be positioned at a predetermined number.

Thereafter, the base 10 is moved in the front-rear direction (the arrow direction in FIG. 6), and the child key 40 is inserted into the adjustment hole 211 of the adjustment plate 20 by the cutter 33 while the pin 32 is inserted into the adjustment hole 211. If the key is sharpened, the child key 40 can be duplicated in the same manner as the parent key. In addition, since the reference numeral 211 indicates the depth of the adjustment hole 211 with a number, the key operator can select the desired adjustment hole 211 at a glance when duplicating the combined key. Convenience can be improved.

As described above, when duplicating the key using the depth adjusting device used in the key duplicating machine according to the present invention, the master key is sandwiched and fixed to the key duplicating machine 30 and the pin 32 is inserted into the key cut portion. There is no need to scrape the child key while abutting, and the parent key does not wear out. Therefore, depending on the depth of the cut portion of the parent key, the adjustment plate 20 is rotated to select an appropriate adjustment hole 211 and the child key is selected. The same cutting portion as that of the master key can be inserted into a desired cutting portion of the material and copied. Therefore, if the present invention is used, the master key will not be worn out no matter how many times the slave key is duplicated, so that the duplicate key can be duplicated with high accuracy.

Since the present invention has the above-described configuration, when duplicating the key, the key maker rotates the adjustment plate according to the depth of the cut portion of the parent key, selects an appropriate adjustment hole, and selects the desired key of the child key. Since the part can be cut, it is not necessary to hold the parent key between the duplicate key duplicator and bring the pin into contact with the parent key cut part, so that the child key does not need to be cut, and the parent key cut part is polished. Therefore, the combined key can be duplicated with high accuracy any number of times without using the parent key.
