Description

Technical Field

[0001] The present disclosure relates to a handle lock device, particularly a handle lock device having a protruding portion that protrudes outside the handle when the handle is engaged, and the handle operation is physically inhibited by the interference of the protruding portion with surrounding objects.

Background Art

[0002] In recent years, as automobile thefts, so-called relay attacks that relay the radio waves of genuine smart keys, and so-called CAN invaders that connect directly to the CAN communication network, transmit commands to unlock door locks and genuine security systems, and start the engine to escape have occurred frequently.

[0003] Therefore, the introduction of after-market anti-theft alarm devices, immobilizer systems, etc., different from genuine products, is considered as a countermeasure. After-market anti-theft alarm devices have a high deterrent effect against thieves, etc., and after-market immobilizer systems have a high crime prevention effect against automobile thefts because the engine cannot be started. However, such systems have a problem that the total cost increases when considering installation costs, etc. because they are after-market.

[0004] Therefore, handle lock devices, etc., which are inexpensive but can be expected to have a certain effect, are widely spread. Here, as a handle lock device, a well-known configuration is one including a sleeve portion, a shaft portion, a first hook portion, a second hook portion, and a fixing portion, which will be described below (see Patent Document 1).

[0005] The sleeve portion is a bottomed cylindrical body. The shaft portion is inserted into the sleeve portion and is held by the sleeve portion so as to be telescopically movable. The first hook portion is arranged at the tip of the shaft portion on the side opposite to the sleeve portion and engages with the handle from the inside. The second hook portion is arranged on the sleeve portion and engages with the handle from the inside. The fixing part fixes the sleeve part and the shaft part in an engaged state where the first hook part and the second hook part are engaged with the handle. And in the engaged state, the sleeve part protrudes outside the handle.

[0006] However, in such a handle lock device, it is only possible to remove the shaft part from the sleeve part, and it has not been easy to add or strengthen functions to the shaft part or the like later. For this reason, it is currently difficult to cope with the forced release of the lock by cutting the shaft part with an electric saw or the like by a car thief.

Summary of the Invention

Problems to be Solved by the Invention

[0008] The present disclosure has been made to solve the above problems, and an object thereof is to provide a handle lock device capable of adding or strengthening functions even later.

Means for Solving the Problems

[0009] The handle lock device of the present disclosure includes a sleeve part, a shaft part, a first hook part, a second hook part, and a fixing part, which will be described below. The sleeve part is a bottomed cylindrical body. The shaft part is inserted into the sleeve part and is held by the sleeve part so as to be telescopic.

[0010] The first hook part is arranged at the tip of the shaft part on the side opposite to the sleeve part and engages with the handle from the inside. The second hook part is arranged on the sleeve part and engages with the handle from the inside. The fixing part fixes the sleeve part and the shaft part in an engaged state where the first hook part and the second hook part are engaged with the handle. And in the engaged state, the sleeve part protrudes outside the handle.

[0011] Here, the first hook part is detachable from the shaft part, and the shaft part has a hollow part that opens to the first hook part side. Thereby, by embedding a functional object in the hollow part, the function of the shaft part can be added and strengthened later. For example, by embedding a columnar body with a higher hardness than the shaft part in the hollow part, the cutting resistance performance of the shaft part can be improved.

Modes for Carrying Out the Invention

[0013] Hereinafter, modes for carrying out the present disclosure will be described based on examples. It goes without saying that the following examples disclose a specific example, and the present disclosure is not limited to the following examples.

Example

[0014] [Configuration of Example 1] The configuration of the handle lock device 1 of Example 1 will be described with reference to FIGS. 1 and 2. The handle lock device 1 includes a sleeve part 2, a shaft part 3, a first hook part 5, a second hook part 6, and a fixing part 8, which will be described below.

[0015] The sleeve portion 2 is a bottomed cylindrical body made of cast iron. The shaft portion 3 is made of cast iron, is inserted into the sleeve portion 2, and is held by the sleeve portion 2 so as to be telescopically movable.

[0016] The first hook portion 5 is disposed at the tip of the shaft portion 3 on the side opposite to the sleeve portion 2 and engages with the handle H from the inside. The second hook portion 6 is disposed on the sleeve portion 2 and engages with the handle H from the inside. The fixing portion 8 is provided on the sleeve portion 2 and fixes the sleeve portion 2 and the shaft portion 3 in an engaged state where the first hook portion 5 and the second hook portion 6 are engaged with the handle H. And, in the engaged state, the sleeve portion 2 has a protruding portion 9 that protrudes outside the handle H (see Fig. 1(b)).

[0017] Here, regarding the fixing mode of the sleeve portion 2 and the shaft portion 3, even when the fixing portion 8 is in a locked state, it may be a fixing mode that does not change the telescopic state of the shaft portion 3, or a so-called ratchet-type fixing mode that allows the shaft portion 3 to extend but does not allow it to contract. Note that, to lock the fixing portion 8, for example, it can be realized by inserting a key into the keyhole and turning the cylinder so that the keyhole reaches the locked position.

[0018] Note that the shaft portion 3 can be removed from the sleeve portion 2 by pulling out the shaft portion 3 from the sleeve portion 2 (see Fig. 1(c)). That is, the shaft portion 3 including the first hook portion 5 can be handled separately from the sleeve portion 2.

[0019] [Characteristic Configuration of Example 1] Here, the first hook portion 5 is detachable from the shaft portion 3, and the shaft portion 3 has a hollow portion 11 that opens to the first hook portion 5 side. More specifically, a male screw 15 is provided on the first hook portion 5, and a female screw 16 is provided on the shaft portion 3. By screwing the male screw 15 and the female screw 16 together or unscrewing them, the first hook portion 5 can be attached to and detached from the shaft portion 3 (see Fig. 2(a)).

[0020] In addition, a hollow portion 11 partitioned into a columnar shape that opens only on the side of the first hook portion 5 is formed in the shaft portion 3 (see Fig. 2(b)). That is, the shaft portion 3 is a bottomed cylindrical body that opens on the side of the first hook portion 5.

[0021] And a columnar body 20 made of SUS304, which is harder than the cast iron shaft portion 3, is embedded in the hollow portion 11. In addition, a plain woven mesh body 22 made of SUS304 is arranged on the surface of the columnar body 20 (see Fig. 2(b)).

[0022] [Effect of Example 1] The handle lock device 1 of Example 1 includes a sleeve portion 2, a shaft portion 3, a first hook portion 5, a second hook portion 6, and a fixing portion 8. The sleeve portion 2 is a bottomed cylindrical body. The shaft portion 3 is inserted into the sleeve portion 2 and is telescopically held by the sleeve portion 2.

[0023] The first hook portion 5 is disposed at the tip of the shaft portion 3 on the side opposite to the sleeve portion 2 and engages with the handle H from the inside. The second hook portion 6 is disposed on the sleeve portion 2 and engages with the handle H from the inside. The fixing portion 8 fixes the sleeve portion 2 and the shaft portion 3 in an engaged state where the first hook portion 5 and the second hook portion 6 are engaged with the handle H. And in the engaged state, the sleeve portion 2 protrudes outside the handle H.

[0024] In addition, the first hook portion 5 is detachable from the shaft portion 3, and the shaft portion 3 has a hollow portion 11 that opens on the side of the first hook portion 5. Further, a columnar body 20 having a higher hardness than the shaft portion 3 is embedded in the hollow portion 11. Furthermore, a net-like body 22 is disposed on the surface of the columnar body 20.

[0025] Here, the first hook portion 5 is detachable from the shaft portion 3, and the shaft portion 3 has a hollow portion 11 that opens to the first hook portion 5 side. Thereby, by embedding a functional object in the hollow portion 11, the function of the shaft portion 3 can be added and enhanced later.

[0026] Also, a columnar body 20 having a higher hardness than the shaft portion 3 is embedded in the hollow portion 11. Thereby, the cut resistance performance of the shaft portion 3 against an electric saw or the like can be improved. In addition, due to a sharp change in hardness, blade breakage of an electric saw or the like can be induced, and the cut resistance performance can be further improved.

[0027] Also, a net-like body 22 is disposed on the surface of the columnar body 20. Thereby, when the net-like body 22 gets caught on the blade of an electric saw or the like, the reciprocating motion of the electric saw or the like can be inhibited. Therefore, the cut resistance performance of the shaft portion 3 against an electric saw or the like can be further improved.

[0028] Although it is difficult to dispose the net-like body 22 alone in the hollow portion 11, for example, the columnar body 20 is fitted into the net-like body 22 formed in a bottomed cylindrical shape, and the net-like body 22 and the columnar body 20 as a core material are integrally fitted into the hollow portion 11 from the open end, so that the net-like body 22 can be easily disposed in the hollow portion 11.

[0029] [Configuration of Example 2] The handle lock device 1 of Example 2 will be described with reference to FIG. 3 centering on the differences from the handle lock device 1 of Example 1. In the handle lock device 1 of Example 2, a columnar body 20 having a higher hardness than the shaft portion 3 is embedded in the hollow portion 11, and a highly viscous body 24 of a rubber-based adhesive is disposed on the surface of the columnar body 20. Note that the highly viscous body 24 may have a viscosity exceeding 100 Pa·s.

[0030] Note that it is difficult to arrange the highly viscous body 24 alone in the hollow portion 11. However, for example, by preparing a columnar body 20 in which the highly viscous body 24 is arranged in advance, the highly viscous body 24 and the columnar body 20 can be integrally fitted into the hollow portion 11 from the open end, and the highly viscous body 24 can be easily arranged in the hollow portion 11.

[0031] [Effect of Example 2] The highly viscous body 24 is arranged on the surface of the columnar body 20. As a result, the highly viscous body 24 wraps around the blade of an electric saw or the like, and chips are clogged between the blades, so that the function of an electric saw or the like can be reduced. Therefore, the cut resistance performance of the shaft portion 3 against an electric saw or the like can be further enhanced.

[0032] [Modification Example] Various modification examples can be considered without departing from the gist of the present invention. For example, in the embodiment, the columnar body 20 made of SUS304 having a higher hardness than the shaft portion 3 was used as the columnar body 20. However, the present invention is not limited to this aspect, and a β-titanium alloy, an alumina sintered body, industrial sapphire, or the like may be used.

[0033] Further, in Example 2, a rubber-based adhesive was used as the highly viscous body 24. However, an acrylic-based adhesive, a silicone-based adhesive, an adhesive having a long curing time, or the like may be used.

[0034] In the embodiment, a male screw 15 is provided on the first hook portion 5 and a female screw 16 is provided on the shaft portion 3. The first hook portion 5 is detachable from the shaft portion 3 by screwing the male screw 15 and the female screw 16 together or unscrewing them. However, the present invention is not limited to this aspect. For example, the first hook portion 5 and the shaft portion 3 may be detachable by a snap fit method.

[0035] In the embodiment, the columnar body 20 embedded in the hollow portion 11 has a higher hardness than the shaft portion 3, and enhances the cutting resistance performance of the shaft portion 3 against an electric saw or the like. In other words, it is so to speak a thing that enhances the function later. On the other hand, for example, a capsule in which a fluorescent paint is enclosed or the like can be embedded in the hollow portion 11. As a result, the fluorescent paint adheres to the clothes of the thief when the shaft portion 3 is cut, and the criminal can be identified quickly. That is, by changing the thing embedded in the hollow portion 11, different functions can be easily added even later.
