Description

  The present invention relates to a portable key device that can be locked and unlocked by a radio wave signal (wireless method) and a metal key for the portable key device.

  Examples of this type of portable key device include those described in Patent Literature 1 and Patent Literature 2. Here, the conventional problems are pointed out by taking Patent Document 1 as an example.

The problem of Patent Document 1 is that when forming a gripping part by molding, if a molding pressure (resin injection pressure) is applied to a holding member that holds an electronic component (transponder), the holding member is released from the handle part of the key plate. Since there exists a possibility, it is fixing the holding member firmly with respect to the handle | pattern part of a keyplate. Therefore, the key device disclosed in Patent Document 1 is a key device in which an electronic component 2 is included in a grip portion 5 formed so as to cover a handle portion (handle portion) 1a of a key plate 1 by molding. The receiving hole 3 for receiving the tapered holding member 4 for holding the electronic component 2 and the connecting hole 12 for the key holder are in communication with each other, and are opened in the handle portion 1a. It has left and right grooves 15 to be engaged with the inner peripheral edge of the receiving hole 3, and the groove 15 is slid to a locking portion protruding from the inner peripheral edge of the receiving hole 3 through a wide connecting hole 12. It is a structure that is fixed to the handle portion 1a by being press-fitted into the receiving hole 3 (the reference numeral is a patent document).
The tapered holding member 4 described in Patent Document 1 must be fixedly set so that there is no gap in the receiving hole 3 of the handle 1a of the key plate 1 (key). The reason is that, when forming the grip portion 5, a molding pressure (resin injection pressure) is applied to the holding member 4 that holds the electronic component (transponder). Therefore, the communication port 13 that connects the receiving hole 3 formed in the handle portion 1a and the connecting hole 12 is held so that both the handle portion 1a of the key plate (key) 1 and the holding member 4 are firmly united. It is necessary to process the inner space so that the member 4 can be firmly locked.

  In addition, the molded-type portable key device needs to be subjected to processing for mounting the electronic component 2 (protrusions, engagement holes, engagement grooves, etc.) on the key 1 itself. In addition, since the entire handle portion 1a of the key itself 1 is molded, a metal key holder or the like cannot be easily hooked on the rear end portion of the resin grip portion 5.

  Further, the resin gripping part 5 that encloses the key 1 or the electronic component 2 cannot be used alone, and the electronic component 2 itself cannot be replaced like a “chip” of a mobile phone. There was also.

  Since Patent Document 2 also processes a part of the handle portion 1a to the insertion portion of the key plate (key) 1 to set the electronic component (transponder) member fixedly at the processing site, it is the same as Patent Document 1. There was a problem.

  Therefore, at least (a) it is not necessary to perform processing (projections, engagement holes, engagement grooves, etc.) for mounting electronic components on the key itself. (B) Appearance of a portable key device that can solve the problem that a metal key holder or the like can be easily hooked to the rear end portion of the knob portion of the metal key itself that penetrates the electronic component storage case. Is desired.

The application of the portable key device of the present invention is also the same.
Now, a kind of electronic component called “transponder” has a simple form in which a coil antenna and a code signal transmission circuit are enclosed in a glass tube or the like, for example. As is well known, the coil antenna exchanges radio signals with the key cylinder side coil provided so as to surround the key hole of the key cylinder.

  That is, when a radio wave is transmitted from a coil on the key cylinder side and the coil antenna of the transponder receives this radio wave, an electromotive force is generated in the coil antenna by electromagnetic induction, and this power is supplied to the code signal transmission circuit and stored in advance. A radio signal corresponding to the unique code is transmitted from the coil antenna, and the unique code signal transmitted from the coil antenna is received by the coil on the key cylinder side and compared with a pre-stored code. If the codes match each other, it is determined that the key is a proper key, and unlocking of the lock and operation of the engine are enabled.

(2) Characteristic Portion As shown in FIG. 1, for example, the portable key device X of the present invention has an opening (long hole-like locking hole) 5 in the protruding rear end portion 4a of the handle portion (handle portion) 4.

FIG. 2 is a front view and the like. For example, in the front view of FIG. 2, an electronic component 21 is housed on the right side of the synthetic resin storage case 11, but the electronic component 21 of the present embodiment has a horizontal direction at the center of the synthetic resin storage case 11. On the other hand, it is positioned at the position of the depression 18 that is eccentric from its intersection “O” with the vertical direction that is the rotation center axis of the key 1 as the Y axis.

  In addition, FIG. 4 is a schematic cross-sectional explanatory diagram based on line 4-4 in FIG. 2, and FIG. 8 is a diagram in which one side case 12 is externally fitted to the key 1, or the key 1 is inserted into the one side case 12. Although it is a schematic explanatory view of the fitted state, as is clear from these drawings, the electronic component 21 housed in the synthetic resin storage case 11 is, for example, one side case 12 such as a polygon or a circle. The inner arcuate surface of the handle portion 4 of the key 1 that is formed in a circular or rectangular recess (small recess) 18 formed on the inner wall surface of the key 1 and whose outer fitting shape is formed in a paper knife shape as a whole. It is provided so as to be located on the outer side with respect to 4b.

(4) Key 1
As shown in FIG. 6, for example, the key 1 constituting the portable key device X is approximately (approximately) the same size as a joinery key or a car key that is generally used on a daily basis. However, the key 1 of the portable key device X according to the present invention is different from a general joinery key or the like in that the shape of the key 1 is a front view as described above, and the outer fitting shape cuts the paper as a whole. The handle portion 4 except for the rear end portion 4a is curved as an inner arcuate surface 4b so that the inside is recessed, while the inner arcuate surface 4b Is that the outer side of the opposite side is an outer arcuate surface 4c protruding in an arcuate shape.

  As described above, the key 1 has a long plate-like insertion portion 2, a wide portion 3 that is connected to the insertion portion with the constricted portion as a boundary, a continuous portion that is connected to the wide portion, and a slightly gentle curvature. A handle portion 4 having an inner arcuate surface 4b and an outer arcuate surface 4c having a larger curvature than the inner arcuate surface 4b and encased in a synthetic resin storage case 11, and the synthetic resin storage case of the handle portion 4 11 is formed with a rear end portion 4a of a handle portion 4 protruding from a notch portion, and a long hole-like locking hole 5 for a key holder is formed in the longitudinal direction of the key 1 in the rear end portion 4a.

  Although not shown in the drawing, the plug-in portion 2 has a bottomed depression having a plurality of types of sizes and depths in the plane portion, or has a notch at the side end of the plane portion. The wide portion 3 starts from the left and right constricted portions 6, 6 corresponding to the base portion of the insertion portion 2, and the remaining portion where the inner and outer arcuate surfaces 4 b, 4 c are connected to the wide portion 3. Corresponds to the handle portion (pattern portion) 4.

  By the way, when the insertion portion 2 is inserted into a lock cylinder (not shown), the distal end side (the narrow portion 6 side) of the wide portion 3 comes into contact with the front surface of the cylinder. The outer shape of the handle portion 4 can be arbitrarily formed as shown in other embodiments.

(5) Synthetic resin storage case 11
For example, as shown in FIG. 7, the synthetic resin storage case 11 is formed of a combination of one side surface case 12 and the other side surface case 13, and an electronic component 21 is fixedly installed in the recess 18.

  In FIG. 1, the electronic component 21 is indicated by an imaginary line at the eccentric position of the synthetic resin storage case 11. 4 is a schematic cross-sectional explanatory diagram based on line 4-4 in FIG. As is apparent from these drawings, the synthetic resin storage case 11 of the present embodiment has a cover other than the insertion portion 2 of the key 1 via, for example, a male / female engaging means (not shown) or a fixing means 17 including a male screw. It is detachably attached to the mounting part (the continuous part of the wide part 3 and the handle part 4).

  That is, the synthetic resin storage case 11 is externally fitted to at least the handle portion 4 except for the rear end portion 4b having the keyhole engaging hole 5 of the handle portion 4 as shown in FIG. And the other side case 13 that is integrally coupled to the one side case 12 leaving the rear end 4b, and at least the one side case 12 or the other side case 13 is formed. A hollow-shaped small recess 18 is formed on any of the inner wall surfaces.

  For example, before joining the one side case 12 having the electronic component 21 to the small recess 18 and the other side case 13, either the one side case 12 or the other side case 13 is connected to the rear end of the key 1. A handle portion 4 excluding the portion 4a is incorporated.

  In the present embodiment, for example, as shown in FIG. 7, a flat frame-shaped and circular one side surface case 12 has symmetrical arc-shaped protruding wall portions at left and right portions of the edge of the wide inner wall surface of the wide flat wall 12a. 12b and 12b, respectively, but between the opposing end portions of the left and right protruding wall portions 12b and 12b, a part of the wide portion of the key 1 other than the above-mentioned mounted portion and the rear end portion of the handle portion 4 Upper and lower cutouts 14 and 14 are formed for projecting. The key 1 is locked so as not to slide on each end (the edge of the notch 14) of the arcuate protruding wall portions 12b and 12b where the notches 14 and 14 are present.

  By the way, the male / female engaging means described above corresponds to, for example, forming either male or female engaging portions on the entire or edge of the arc-shaped protruding wall portion 12b of the one side surface case 12, and corresponding to this. A female or male engagement portion is formed on the left and right arcuate protruding wall portions 13b, 13b of the other side case 13 or the like.

  Further, as shown in FIG. 7, the fixing means 17 described above includes, for example, a short cylindrical female screw portion (female screw column) 15 protruding from an eccentric position of the wide inner wall surface of the wide flat wall 12 a of the one side surface case 12. A through hole 16 formed at an eccentric position of the wide flat wall 13a of the other side case 13 so as to face the female screw portion, and the one side surface case 12 through the through small hole 16 and the female screw portion 15. And an unnumbered male screw integrally connecting the other side case 13.

  Therefore, the synthetic resin storage case 11 of the embodiment can be separated into the one side surface case 12 and the other side surface case 13, and when the synthetic resin storage case 11 is separated, the key itself is attached to an ordinary machine. It can be used alone as an expression key.

  Next, in this section, referring to FIGS. 9 to 15, the second embodiment, the third embodiment, the fourth embodiment and the fifth embodiment of the present invention having the same effects as those of the first embodiment are described. explain. In these embodiments, the same parts as those in the first embodiment or the second embodiment are denoted by the same or similar reference numerals, and redundant description is omitted.

  First, in the second embodiment shown in FIG. 9, the main differences from the first embodiment are formed in the one side case 12A and / or the other side case 13A of the synthetic resin storage case 11A. This is a depression 18. The dent 18 of the first embodiment is a small recess formed at the eccentric position of the wide flat wall 12a of the one side surface case 12, for example. The dent 18 of the second embodiment is, for example, a one side surface case. The difference is that it is a surrounding frame 19 formed in a rectangular shape on the inner wall surface of the 12A wide flat wall 12a. The enclosure frame 19 forming the recess 18 may be not only a polygon but also a circle. Therefore, the shape and configuration of the recess 18 are not essential matters of the present invention.

  Next, the third embodiment shown in FIGS. 10 and 11 is mainly different from the second embodiment in that (a) the shape of the handle portion 4A of the key 1A is partially changed. b) The short cylindrical female screw portion (female screw column) 15 and the through small hole 16 constituting the fixing means 26A are formed in the central portion of the synthetic resin storage case 11A. In particular, the former (a) is a lock for a female screw portion (female screw column) 15 having a stopper function that is formed at the substantially central portion of the inner arcuate surface 4b of the handle portion 4A and protruding from the central portion of the one side surface case 12A. With this configuration, which is characterized in that the notch 4d is formed, the key 1A and the synthetic resin storage case 11A are further combined. Therefore, the position of the fixing means 26A with respect to the synthetic resin storage case 11A is not an essential matter of the present invention.

  Next, in the fourth embodiment shown in FIG. 12, the main difference from the second embodiment is an opening (locking hole) 5B formed in the rear end portion 4a of the key 1B. For example, as apparent from comparing the phantom key 1 shown in FIG. 9 and the solid key 1B shown in FIG. 12, the locking hole 5B of the key 1B of the second embodiment intersects the longitudinal direction of the key 1B. The horizontal direction is formed in the shape of a slightly wide slot. Since the shape of the locking hole 5B of the key 1B is for hooking a key holder (not shown), the design can be arbitrarily changed.

  Finally, the fifth embodiment shown in FIGS. 13 to 15 is mainly different from the first embodiment in that (a) the characteristic of the third embodiment (the fixing means 26A is made of a synthetic resin storage case 11A). (B) the electronic component 21 is supported on the one side surface of the key 1C, in other words, on the one side surface of the handle portion 4C of the key 1C. In other words, the electronic component 21 to be attached in the state is built in the eccentric position of the synthetic resin storage case 11C. In the fifth embodiment, a concave small recess 18 similar to that of the first embodiment is formed at the eccentric position of the inner wall surface of the other side surface case 13C instead of the one side surface case 12C side. Of course, the small recess 18 may be the small recess 18 formed in the enclosure frame 19 of the second embodiment.
