Description

本発明は、自動車のステアリングシャフトの回転をロックするステアリングロック装置に関する。   The present invention relates to a steering lock device that locks rotation of a steering shaft of an automobile.

この種の従来のステアリングロック装置としては、特許文献１に開示されたものがある。このステアリングロック装置１００は、図７、図８に示すように、ステアリングシャフト１０１の回転を阻止するロック位置とステアリングシャフト１０１の回転を許容するロック解除位置との間で変位するロック部材１０２と、このロック部材１０２を解錠方向及び施錠方向に駆動する作動体１０３とを本体フレーム１０４及び樹脂製カバー１０５によって形成される部品収容室１０６内に収容している。カバー１０５の内側には、鉄板などの硬質材料をＬ字形に折曲げることにより形成された補強部材１０７が設けられている。この補強部材１０７の横板部１０７ａを本体フレーム１０４の一部にかしめ止めすることにより、横板部１０７ａを本体フレーム１０４に対して部分的に固着させるとともに、縦板部１０７ｂが仕切り板１０８の外面に接合されている。   A conventional steering lock device of this type is disclosed in Patent Document 1. As shown in FIGS. 7 and 8, the steering lock device 100 includes a lock member 102 that is displaced between a lock position that prevents rotation of the steering shaft 101 and a lock release position that allows rotation of the steering shaft 101; An operating body 103 that drives the lock member 102 in the unlocking direction and the locking direction is housed in a component housing chamber 106 formed by a main body frame 104 and a resin cover 105. A reinforcement member 107 formed by bending a hard material such as an iron plate into an L shape is provided inside the cover 105. By fixing the horizontal plate portion 107 a of the reinforcing member 107 to a part of the main body frame 104, the horizontal plate portion 107 a is partially fixed to the main body frame 104, and the vertical plate portion 107 b is fixed to the partition plate 108. It is joined to the outer surface.

上記構成において、ロック部材１０２がロック位置でステアリングシャフト１０１を施錠することによって、駐車中の車両盗難を防止することができる。しかしながら、樹脂製カバー１０５等を溶かすなどにより小さな貫通穴を開け、この貫通穴を介してロック部材１０２を直接操作してロック解除位置側に移動させる行為（いわゆるソフトアタック）により、ステアリングシャフト１０１の施錠状態が強制的に解除されて、駐車中の自動車が盗まれるということがあった。そこで、前記のようにカバー１０５の内側に補強部材１０７を設けることにより、駐車中にスライドハンマなどの破壊工具を用いてカバー１０５に外側から貫通穴を開けても、その内側の補強部材１０７が破壊されることがないので、ロック部材１０２の不正なロック解除を抑制することができる。
実開平５−１３８６７号公報 In the above configuration, the lock member 102 locks the steering shaft 101 at the lock position, thereby preventing vehicle theft during parking. However, by opening the small through hole by melting the resin cover 105 or the like and operating the lock member 102 directly through the through hole to move to the unlock position side (so-called soft attack), the steering shaft 101 In some cases, the locked state was forcibly released and the parked car was stolen. Therefore, by providing the reinforcing member 107 on the inner side of the cover 105 as described above, even if a through hole is made in the cover 105 from the outside using a breaking tool such as a slide hammer during parking, the inner reinforcing member 107 does not move. Since it is not destroyed, unauthorized unlocking of the lock member 102 can be suppressed.
Japanese Utility Model Publication No. 5-13867

しかしながら、従来のステアリングロック装置１００では、補強部材１０７の横板部１０７ａが本体フレーム１０４の一部にかしめ止めされているので、カバー１０５を外側からハンマなどで叩くことにより補強部材１０７のかしめ止め部に衝撃力を加えた場合、補強部材１０７が本体フレーム１０４から外れて所定位置からずれてしまうので、補強部材１０７でカバー１０５を補強することが難しくなり、ロック部材１０２の不正なロック解除を防止する効果が低下するという懸念がある。   However, in the conventional steering lock device 100, since the lateral plate portion 107a of the reinforcing member 107 is caulked to a part of the main body frame 104, the caulking of the reinforcing member 107 is prevented by hitting the cover 105 with a hammer or the like from the outside. When the impact force is applied to the portion, the reinforcing member 107 is detached from the predetermined position by being disengaged from the main body frame 104, so that it is difficult to reinforce the cover 105 with the reinforcing member 107, and the lock member 102 is illegally unlocked. There is concern that the effect of preventing will be reduced.

なお、補強部材１０７を本体フレーム１０４にかしめ止めする代わりに、カバーの内面に補強部材を熱溶着することにより、補強部材をカバーに対して部分的に固着させることも考えられるが、この場合も、前記熱溶着部に衝撃力を加えたとき熱溶着部が剥離して補強部材が所定位置からずれてしまうので、補強部材でカバーを補強することが難しくなる。   Instead of caulking the reinforcing member 107 to the main body frame 104, it may be possible to partially fix the reinforcing member to the cover by thermally welding the reinforcing member to the inner surface of the cover. When an impact force is applied to the heat welded portion, the heat welded portion is peeled off and the reinforcing member is displaced from a predetermined position, so that it is difficult to reinforce the cover with the reinforcing member.

そこで、本発明は、外側からの衝撃力に対してもカバーを補強する効果を維持してロック部材の不正なロック解除を阻止でき、駐車中における車両盗難を防止することができるステアリングロック装置を提供することを目的とする。   Therefore, the present invention provides a steering lock device that can maintain the effect of reinforcing the cover against impact force from the outside, prevent unauthorized unlocking of the lock member, and prevent vehicle theft during parking. The purpose is to provide.

上記目的を達成する請求項１の発明は、ステアリングシャフトの回転を阻止するロック位置と前記ステアリングシャフトの回転を許容するロック解除位置との間で変位するロック部材と、このロック部材を解錠方向及び施錠方向に駆動する作動体とを、本体フレーム及び箱状カバーによって形成される部品収容室内に収容したステアリングロック装置において、前記箱状カバーの内側に、金属板から形成され、基板部と、この基板部の両側より折曲げられるとともに、互いに対向する一対の側板部とを有する補強部材が設けられ、前記一対の側板部の各端部が、前記本体フレーム及び前記箱状カバーによって挟持されたことを特徴とする。   The invention according to claim 1, which achieves the above object, includes a lock member that is displaced between a lock position that prevents rotation of the steering shaft and a lock release position that allows rotation of the steering shaft, and the unlocking direction of the lock member. And a steering lock device in which the operating body driven in the locking direction is housed in a component housing chamber formed by a main body frame and a box-shaped cover, and is formed from a metal plate inside the box-shaped cover, A reinforcing member having a pair of side plate portions facing each other and being bent from both sides of the substrate portion is provided, and each end portion of the pair of side plate portions is sandwiched between the main body frame and the box-shaped cover. It is characterized by that.

請求項２の発明は、請求項１記載のステアリングロック装置であって 前記基板部と前記一対の側板部との間に形成される折曲部に、スリットを設けたことを特徴とする。   A second aspect of the present invention is the steering lock device according to the first aspect, wherein a slit is provided in a bent portion formed between the substrate portion and the pair of side plate portions.

請求項１の発明によれば、本体フレームに箱状カバーを装着する際に、この箱状カバーの内側に、一対の側板部を立設させた状態で補強部材を配置するとともに、一対の側板部の各端部を本体フレーム及び箱状カバーによって挟持する。このようにしてステアリングロック装置を組み立てた後、箱状カバーを外側からハンマなどで叩くことにより補強部材の基板部に衝撃力を加えた場合、補強部材の基板部の両端が一対の側板部により支持されているので、前記衝撃力を基板部で受けるとともに、基板部が所定位置からずれることを抑制できる。また、箱状カバーを外側からハンマなどで叩くことにより一方の側板部に衝撃力を加えた場合、この側板部の一端が基板部に連結され、他端が本体フレーム及び箱状カバーによって挟持されているので、前記衝撃力を一方の側板部で受けるとともに、一方の側板部が所定位置からずれることを抑制できる。これにより、外側からの衝撃力に対しても箱状カバーを補強する効果を維持してロック部材の不正なロック解除を阻止でき、駐車中における車両盗難を防止することができる。   According to the first aspect of the present invention, when the box-shaped cover is mounted on the main body frame, the reinforcing member is disposed in a state where the pair of side plate portions are erected on the inner side of the box-shaped cover, and the pair of side plates. Each end of the unit is sandwiched between the main body frame and the box-shaped cover. After assembling the steering lock device in this way, when an impact force is applied to the substrate portion of the reinforcing member by hitting the box-shaped cover with a hammer or the like from the outside, both ends of the substrate portion of the reinforcing member are separated by a pair of side plate portions. Since it is supported, the impact force is received by the substrate portion, and the substrate portion can be prevented from shifting from a predetermined position. In addition, when an impact force is applied to one side plate portion by hitting the box-shaped cover with a hammer or the like from the outside, one end of this side plate portion is connected to the substrate portion, and the other end is sandwiched between the main body frame and the box-shaped cover. Therefore, while receiving the said impact force by one side plate part, it can suppress that one side plate part shifts | deviates from a predetermined position. Thereby, it is possible to prevent the lock member from being illegally unlocked while maintaining the effect of reinforcing the box-shaped cover against the impact force from the outside, and to prevent vehicle theft during parking.

請求項２の発明によれば、請求項１の発明の効果に加え、折曲部にスリットを設けたことにより、補強部材が加えられた衝撃力によって変形しやすくなり、箱状カバーが脱落しにくくなるため、防盗性能をより向上できる。   According to the invention of claim 2, in addition to the effect of the invention of claim 1, by providing a slit in the bent portion, the reinforcing member is easily deformed by the applied impact force, and the box-shaped cover falls off. Because it becomes difficult, anti-theft performance can be improved.

以下、本発明の一実施形態を図面に基づいて説明する。図１〜図６は本発明の一実施形態を示し、図１はステアリングロック装置１の分解斜視図、図２は箱状カバー３及び補強部材６を開口３ｆ側から見た図、図３は図２のＡ−Ａ線に沿う断面図、図４は図２のＢ−Ｂ線に沿う断面図、図５は補強部材６の斜視図、図６は箱状カバー３を開口３ｆ側から見た斜視図である。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 6 show an embodiment of the present invention, FIG. 1 is an exploded perspective view of a steering lock device 1, FIG. 2 is a view of a box-like cover 3 and a reinforcing member 6 viewed from the opening 3f side, and FIG. 2 is a cross-sectional view taken along line AA in FIG. 2, FIG. 4 is a cross-sectional view taken along line BB in FIG. 2, FIG. 5 is a perspective view of the reinforcing member 6, and FIG. FIG.

図１〜図６に示すように、ステアリングロック装置１は、互いに組み付けられ、内部に部品収容室を形成する本体フレーム２及び箱状カバー３と、この部品収容室内に収容され、図示しないステアリングシャフトの回転を阻止するロック位置とステアリングシャフトの回転を許容するロック解除位置との間で変位するロック部材４と、このロック部材４を解錠方向及び施錠方向に駆動する作動体５と、例えば鉄板などの延性が高い金属板から形成され、箱状カバー３の内側に設けられる補強部材６とを備えている。   As shown in FIGS. 1 to 6, the steering lock device 1 is assembled with each other, and a main body frame 2 and a box-shaped cover 3 that form a component accommodating chamber therein, and a steering shaft (not shown) accommodated in the component accommodating chamber. A lock member 4 that is displaced between a lock position that prevents the rotation of the steering shaft and a lock release position that permits the rotation of the steering shaft, an operating body 5 that drives the lock member 4 in the unlocking direction and the locking direction, and an iron plate, for example. And a reinforcing member 6 formed on the inside of the box-shaped cover 3.

箱状カバー３は、樹脂からなり、本体フレーム２上に所定間隔をおいて配置される長方形状の基板部３ａと、この基板部３ａの長手方向に延びるとともに、互いに対向する一対の側板部３ｂ、３ｃと、基板部３ａの短手方向に延びるとともに、互いに対向するもう一対の側板部３ｄ、３ｅとから一体に形成されている。また、箱状カバー３の基板部３ａの反対側に、本体フレーム２上に載置される開口３ｆを有している。   The box-shaped cover 3 is made of resin and has a rectangular substrate portion 3a disposed on the main body frame 2 at a predetermined interval, and a pair of side plate portions 3b that extend in the longitudinal direction of the substrate portion 3a and face each other. 3c and another pair of side plate portions 3d and 3e extending in the short direction of the substrate portion 3a and facing each other. The box-shaped cover 3 has an opening 3 f placed on the main body frame 2 on the opposite side of the substrate portion 3 a.

補強部材６は、基板部６ａと、この基板部６ａの両側より直角に折曲げられるとともに、互いに対向する一対の側板部６ｂ，６ｃとから構成されている。これらのうち基板部６ａと一方の側板部６ｂとの間に形成される折曲部６ｄには、スリット６ｆが断続的に形成されており、すなわち、基板部６ａと一方の側板部６ｂとが折曲部６ｄを介して部分的にのみ連結されている。同様に、基板部６ａと他方の側板部６ｃとの間に形成される折曲部６ｅにも、スリット６ｇが断続的に形成されており、すなわち、基板部６ａと他方の側板部６ｃとが折曲部６ｅを介して部分的にのみ連結されている。また、本体フレーム２に箱状カバー３を装着した状態で、一対の側板部６ｂ、６ｃの各端部が本体フレーム２及び箱状カバー３によって挟持されている。   The reinforcing member 6 includes a substrate portion 6a and a pair of side plate portions 6b and 6c that are bent at right angles from both sides of the substrate portion 6a and face each other. Among these, a slit 6f is intermittently formed in the bent portion 6d formed between the substrate portion 6a and the one side plate portion 6b, that is, the substrate portion 6a and the one side plate portion 6b are formed. Only partially connected via the bent portion 6d. Similarly, slits 6g are intermittently formed in the bent portion 6e formed between the substrate portion 6a and the other side plate portion 6c, that is, the substrate portion 6a and the other side plate portion 6c are formed. Only partially connected via the bent portion 6e. Further, the end portions of the pair of side plate portions 6 b and 6 c are sandwiched between the main body frame 2 and the box-shaped cover 3 with the box-shaped cover 3 attached to the main body frame 2.

次に、前記ステアリングロック装置１の動作を説明する。本体フレーム２に箱状カバー３を装着する際に、この箱状カバー３の内側に、一対の側板部６ｂ、６ｃを立設させた状態で補強部材６を配置するとともに、一対の側板部６ｂ、６ｃの各端部を本体フレーム２及び箱状カバー３によって挟持する。このようにしてステアリングロック装置１を組み立てたとき、箱状カバー３の基板部３ａの内面に箱状カバー３の基板部６ａが接合されるとともに、箱状カバー３の側板部３ｄ、３ｅの各内面に箱状カバー３の側板部６ｂ、６ｃがそれぞれ接合されている。   Next, the operation of the steering lock device 1 will be described. When the box-shaped cover 3 is attached to the main body frame 2, the reinforcing member 6 is disposed inside the box-shaped cover 3 with the pair of side plate portions 6b and 6c being erected, and the pair of side plate portions 6b. , 6c is sandwiched between the main body frame 2 and the box-shaped cover 3. When the steering lock device 1 is assembled in this way, the substrate portion 6a of the box-shaped cover 3 is joined to the inner surface of the substrate portion 3a of the box-shaped cover 3, and each of the side plate portions 3d, 3e of the box-shaped cover 3 is joined. Side plate portions 6b and 6c of the box-shaped cover 3 are joined to the inner surface, respectively.

この状態で箱状カバー３を図示しないハンマなどで叩くことにより補強部材６の基板部６ａに衝撃力を加えた場合、この基板部６ａの両端が折曲部６ｄ，６ｅを介して一対の側板部６ｂ、６ｃにより支持されているので、前記衝撃力を基板部６ａで受けるとともに、基板部６ａが所定位置からずれることを抑制できる。   When an impact force is applied to the substrate portion 6a of the reinforcing member 6 by hitting the box-shaped cover 3 with a hammer (not shown) in this state, both ends of the substrate portion 6a are connected to the pair of side plates via the bent portions 6d and 6e. Since it is supported by the portions 6b and 6c, the impact force is received by the substrate portion 6a, and the substrate portion 6a can be prevented from being displaced from a predetermined position.

また、箱状カバー３を側方からハンマなどで叩くことにより一方の側板部６ｂに衝撃力を加えた場合、この側板部６ｂの一端が折曲部６ｄを介して基板部６ａに連結され、他端が本体フレーム２及び箱状カバー３によって挟持されているので、前記衝撃力を側板部６ｂで受けるとともに、側板部６ｂが所定位置からずれることを抑制できる。なお、他方の側板部６ｃに衝撃力を加えた場合も同様である。   Further, when an impact force is applied to one side plate portion 6b by hitting the box-shaped cover 3 from the side with a hammer or the like, one end of the side plate portion 6b is connected to the substrate portion 6a via the bent portion 6d. Since the other end is sandwiched between the main body frame 2 and the box-shaped cover 3, the impact force is received by the side plate portion 6b, and the side plate portion 6b can be prevented from shifting from a predetermined position. The same applies when an impact force is applied to the other side plate portion 6c.

また、基板部６ａと一方の側板部６ｂとが折曲部６ｄを介して部分的にのみ連結され、同様に、基板部６ａと他方の側板部６ｃとが折曲部６ｅを介して部分的にのみ連結されているので、基板部６ａと側板部６ｂ、６ｃのそれぞれの剛性が低下し、外側から衝撃力が加えられた際に変形して前記衝撃力を吸収しやすい。   Further, the substrate portion 6a and one side plate portion 6b are only partially connected via the bent portion 6d, and similarly, the substrate portion 6a and the other side plate portion 6c are partially connected via the bent portion 6e. Therefore, the rigidity of each of the substrate portion 6a and the side plate portions 6b and 6c is lowered, and when the impact force is applied from the outside, the substrate portion 6a is deformed and easily absorbs the impact force.

さらに、折曲部６ｄ，６ｅにスリット６ｆ，６ｇを設けたことにより、補強部材６が衝撃力によって変形しやすくなり、箱状カバー３と補強部材６が脱落しにくくなる。   Furthermore, by providing the slits 6f and 6g in the bent portions 6d and 6e, the reinforcing member 6 is easily deformed by an impact force, and the box-shaped cover 3 and the reinforcing member 6 are not easily dropped.

以上、本発明では、外側から箱状カバー３に加えられた衝撃力を補強部材６で受ける際に、基板部６ａ及び側板部６ｂ、６ｃが所定位置からずれることを抑制できるので、補強部材６による箱状カバー３の補強効果を維持して、ロック部材４の不正なロック解除をより確実に阻止できる。その結果、外部からロック部材４を操作して強制的に解錠しようとする破壊行為から保護することができ、駐車中における防盗性（車両盗難を防止する性能）を向上できる。   As described above, in the present invention, when the impact force applied to the box-shaped cover 3 from the outside is received by the reinforcing member 6, it is possible to suppress the substrate portion 6a and the side plate portions 6b and 6c from being displaced from the predetermined positions. The reinforcing effect of the box-shaped cover 3 can be maintained, and unauthorized unlocking of the lock member 4 can be more reliably prevented. As a result, it is possible to protect against a destructive act of forcibly unlocking by operating the lock member 4 from the outside, and the anti-theft property (performance for preventing vehicle theft) during parking can be improved.

この実施形態では、基板部６ａと側板部６ｂ、６ｃのそれぞれの剛性を低下させたことにより、外側から衝撃力が加えられた際に基板部６ａと側板部６ｂ、６ｃのそれぞれが変形して前記衝撃力を吸収できるので、基板部６ａ及び側板部６ｂ、６ｃが所定位置からずれることをより確実に抑制できる。   In this embodiment, by reducing the rigidity of each of the substrate portion 6a and the side plate portions 6b and 6c, each of the substrate portion 6a and the side plate portions 6b and 6c is deformed when an impact force is applied from the outside. Since the said impact force can be absorbed, it can suppress more reliably that the board | substrate part 6a and the side-plate parts 6b and 6c shift | deviate from a predetermined position.

この実施形態では、金属板を折曲げることにより補強部材６を形成し、箱状カバー３の内側に一対の側板部６ｂ、６ｃを立設させた状態で補強部材６を配置するので、補強部材６を本体フレーム２あるいは箱状カバー３に熱溶着やかしめ止め等で固着させる必要がなくて済み、補強部材６を固着させる手間を省くことができるとともに、固着させた部分が外れて補強部材６が所定位置からずれることを防止できる。   In this embodiment, the reinforcing member 6 is formed by bending a metal plate, and the reinforcing member 6 is disposed in a state where the pair of side plate portions 6b and 6c are erected on the inner side of the box-shaped cover 3, so that the reinforcing member 6 is not required to be fixed to the main body frame 2 or the box-shaped cover 3 by heat welding, caulking, or the like, and the trouble of fixing the reinforcing member 6 can be omitted, and the fixed portion is detached and the reinforcing member 6 is removed. Can be prevented from deviating from a predetermined position.

この実施形態では、１枚の金属板を折曲げることにより基板部６ａと一対の側板部６ｂ、６ｃからなる補強部材６を形成し、箱状カバー３の３つの面（上面及び両側面）の補強を行なうようにしたので、２枚あるいは３枚の金属板を組み合わせることによって、３つの面の補強を行なう補強部材を形成する場合に比べて、部品点数の削減及び組立工法の簡易化を図ることができる。   In this embodiment, a reinforcing member 6 including a substrate portion 6a and a pair of side plate portions 6b and 6c is formed by bending a single metal plate, and the three surfaces (upper surface and both side surfaces) of the box-shaped cover 3 are formed. Since the reinforcement is performed, by combining two or three metal plates, the number of parts can be reduced and the assembly method can be simplified as compared with the case of forming the reinforcing member that reinforces the three surfaces. be able to.

また、折曲部にスリットを設けたことにより、補強部材が加えられた衝撃力によって変形しやすくなり、箱状カバーが脱落しにくくなるため、防盗性能をより向上できる。   In addition, since the slit is provided in the bent portion, the reinforcing member is easily deformed by the applied impact force, and the box-shaped cover is difficult to drop off, so that the anti-theft performance can be further improved.
