Among them, the horseshoe lock that inserts a saddle between spokes of the wheel to prevent the rotation of the wheel is easy to attach to the bicycle body with a simple structure, and also to be easily locked and unlocked. There are features.

このため、馬蹄型錠は、普及している自転車用錠装置の一つであり、この馬蹄型錠に関する発明も数多く提案されている(例えば特許文献1参照)。また最近では、馬蹄型錠の素材として、加工が容易でありデザイン性に優れた、アルミニウム、亜鉛または樹脂などが用いられている。   For this reason, the horseshoe lock is one of the popular bicycle locking devices, and many inventions relating to this horseshoe lock have been proposed (see, for example, Patent Document 1). In recent years, aluminum, zinc, resin, or the like, which is easy to process and has excellent design, has been used as a material for horseshoe-shaped tablets.

A knob slit 15 shown in FIG. 2B is formed at the position of 240 ° to 310 ° of the main body 12 when bonded.

上記カバー体31は、図3に示すように、裏板21の板部22と平行に配置されて当該板部22に形成されたリベット穴23に対応する位置にリベット穴33が形成されたC形の表板部32と、この表板部32の縁から突設させて裏板21の裏縁部24と当接する表縁部34と、上記表板部32の内周の左右側に設けられて本体部12を取付用台座8へ取り付けるための取付穴36が形成された左右一対の取付部35と、表板部32の外周の約220°の位置に設けられるとともに鍵の差入および回転により閂11を固定し得る鍵穴部37とから構成されている。また、カバー体31は、素材としてアルミニウムが用いられている。   As shown in FIG. 3, the cover body 31 is arranged in parallel with the plate portion 22 of the back plate 21 and has a rivet hole 33 formed at a position corresponding to the rivet hole 23 formed in the plate portion 22. A front plate portion 32 having a shape, a front edge portion 34 projecting from the edge of the front plate portion 32 and contacting the back edge portion 24 of the back plate 21, and provided on the left and right sides of the inner periphery of the front plate portion 32. And a pair of left and right attachment portions 35 in which attachment holes 36 for attaching the main body portion 12 to the attachment base 8 are formed, and the outer periphery of the front plate portion 32 is provided at a position of about 220 ° and the insertion of a key. It is comprised from the keyhole part 37 which can fix the collar 11 by rotation. The cover body 31 is made of aluminum as a material.

図3に示すように、上記閂11は、C形の本体部12と同心の円弧形状で断面六角形の棒材であって、円弧角が180°相当の長さを有し、素材として鉄が用いられている。また、この閂11の一部には、当該閂11をスライドさせて本体部12の一方の下端部13Lから他方の下端部13Rに嵌入するための操作用つまみ16が、外周側に向けて取り付けられている。さらに図2に示すように、本体部12において、閂11が本体部12の内部である空間部14に収容されるとともに、操作用つまみ16が上記つまみ用スリット15を通って本体部12の外部に出るように配置されている。   As shown in FIG. 3, the flange 11 is a bar having an arc shape and a hexagonal cross section concentric with the C-shaped main body 12, and has a length corresponding to a circular arc angle of 180 °. Is used. In addition, an operation knob 16 for sliding the collar 11 to fit from one lower end 13L of the main body 12 to the other lower end 13R is attached to a part of the collar 11 toward the outer peripheral side. It has been. Further, as shown in FIG. 2, in the main body 12, the collar 11 is accommodated in the space 14 inside the main body 12, and the operation knob 16 passes through the knob slit 15 to the outside of the main body 12. It is arranged to come out.

一方、図2、図3および図7に示すように、カバー体31を構成する表板部32の表面には、2つの構成部材42R,42Lからなる補強材41が取り付けられている。具体的には、図4に示すように、表板部32の表面の40°〜150°および210°〜320°の位置に、構成部材42R,42Lがそれぞれ取り付けられている。すなわち、各構成部材42R,42Lは、90°および270°の位置を覆うため、これら90°および270°の位置を結ぶ水平中心線(図4参照)と交差するように配置されている。言い換えれば、上記補強材41の取付位置は、図6に示すように、自転車1の後輪3の左右両面から膨出した箇所であり、自転車用錠装置10をケーブルカッターCなどで破壊・切断する際に狙われやすい箇所である。   On the other hand, as shown in FIGS. 2, 3, and 7, a reinforcing member 41 including two constituent members 42 </ b> R and 42 </ b> L is attached to the surface of the front plate portion 32 that constitutes the cover body 31. Specifically, as shown in FIG. 4, the constituent members 42R and 42L are respectively attached at positions of 40 ° to 150 ° and 210 ° to 320 ° on the surface of the front plate portion 32. That is, each of the constituent members 42R and 42L is disposed so as to intersect the horizontal center line (see FIG. 4) connecting the 90 ° and 270 ° positions in order to cover the 90 ° and 270 ° positions. In other words, as shown in FIG. 6, the attachment position of the reinforcing member 41 is a portion that bulges from the left and right sides of the rear wheel 3 of the bicycle 1, and the bicycle locking device 10 is broken and cut by the cable cutter C or the like. It is a place that is easy to be targeted when doing.

また、図3に示すように、この補強材41のカバー体31への取り付けと、裏板21とカバー体31との接合には、いずれも、上記リベット穴23,33を貫通させる貫通リベット43が用いられている。これら貫通リベット43は、素材として鉄が用いられており、本体部12の空間部14における閂11のスライドを妨げない位置に配置される。   Further, as shown in FIG. 3, a penetration rivet 43 that penetrates the rivet holes 23 and 33 is used for attaching the reinforcing member 41 to the cover body 31 and joining the back plate 21 and the cover body 31. Is used. These penetrating rivets 43 are made of iron as a material, and are arranged at positions that do not hinder the sliding of the collar 11 in the space 14 of the main body 12.

次に、上記構成における作用および効果について説明する。
図5に示すように、予めこの自転車用錠装置10は、本体部12の取付部35に形成された取付穴36にねじを挿入して、取付用台座8のねじ穴9に螺合することで、自転車1のバックホーク7に取り付けられている。
Next, the operation and effect of the above configuration will be described.
As shown in FIG. 5, the bicycle locking device 10 previously inserts a screw into a mounting hole 36 formed in the mounting portion 35 of the main body portion 12 and is screwed into the screw hole 9 of the mounting base 8. It is attached to the back hawk 7 of the bicycle 1.

この自転車用錠装置10の施錠時には、操作用つまみ16を手動によりつまみ用スリット15の上端(310°の位置)から下端(240°の位置)までスライドさせることで、本体部12に収容された閂11もスライドされて、この閂11を一方の下端部13Lから後輪3のスポーク4間に通過させて他方の下端部13Rに嵌入させる。また、解錠時には、鍵穴部37の鍵穴に鍵を差し込んで回転させ、リターンばねにより閂11を一方の下端部13Lから空間部14に収容させる。   When the bicycle locking device 10 is locked, the operation knob 16 is manually slid from the upper end (position of 310 °) to the lower end (position of 240 °) of the knob slit 15 to be accommodated in the main body 12. The flange 11 is also slid, and the flange 11 is passed between the spokes 4 of the rear wheel 3 from one lower end portion 13L and fitted into the other lower end portion 13R. At the time of unlocking, a key is inserted into the keyhole of the keyhole portion 37 and rotated, and the flange 11 is accommodated in the space portion 14 from one lower end portion 13L by a return spring.

このため、施錠した状態で自転車1を移動させる場合などでは、後輪3が回転して閂11に後輪3のスポーク4が当たり、閂11を収容した本体部12に曲げモーメントが作用することになる。しかし、この曲げモーメントによる引張応力または圧縮応力が最大となる本体部12の外殻には、カバー体31の素材(アルミニウム)よりも機械的強度の高い素材(鉄)を用いた裏板21が配設されているので、カバー体31への曲げモーメントによる負担が軽減される。したがって、本体部12の曲がりを防止でき、閂11の出退が不良になることを防止できる。   For this reason, when the bicycle 1 is moved in a locked state, the rear wheel 3 rotates, the spoke 4 of the rear wheel 3 hits the saddle 11, and a bending moment acts on the main body 12 containing the saddle 11. become. However, a back plate 21 made of a material (iron) having a mechanical strength higher than that of the material (aluminum) of the cover body 31 is formed on the outer shell of the main body 12 where the tensile stress or the compressive stress due to the bending moment is maximized. Since it is disposed, the burden caused by the bending moment on the cover body 31 is reduced. Therefore, the bending of the main body portion 12 can be prevented, and it is possible to prevent the eaves / recesses of the ridge 11 from becoming defective.

また、自転車用錠装置10を破壊・切断する際に狙われやすい箇所である水平中心線付近を、補強材41により集中的に保護しているので、本体部12は少ない補強材41で効率よく保護され、防犯性能を向上させることができる。   Further, since the vicinity of the horizontal center line, which is easily targeted when breaking or cutting the bicycle locking device 10, is intensively protected by the reinforcing material 41, the main body 12 can be efficiently used with few reinforcing materials 41. It is protected and the crime prevention performance can be improved.

なお、本実施の形態1に係る自転車用錠装置10は、カバー体31の素材として加工が容易な金属であるアルミニウムが用いられていることから、カバー体31をダイキャストなどで容易に製造および加工できる。   Since the bicycle locking device 10 according to the first embodiment uses aluminum, which is a metal that can be easily processed, as the material of the cover body 31, the cover body 31 can be easily manufactured and die-cast. Can be processed.

(実施の形態2)

A reinforcing member 51 is provided. Further, since the reinforcing member 52 constituting the reinforcing member 51 has the reinforcing edge portion 54 protruding from the reinforcing plate 53, the reinforcing member 52 has a cross-sectional shape that is not easily deformed by an external force. For this reason, the burden by the bending moment to the cover body 31 is further reduced. Therefore, the bending of the main body portion 12 can be further prevented, and it can be further prevented that the eaves / recesses of the flange 11 become defective.

また、補強縁部54を有する補強材51により、本体部12表面の略全周および表縁部34を保護しているので、本体部12は強固に保護されるとともに補強されるので、防犯性能をより一層向上させることができる。したがって、本自転車用錠装置10をケーブルカッターCなどで破壊・切断しようとしても、これを補強縁部54を有する補強材51で困難にし、ひいては、自転車用錠装置10を悪戯や盗難に遭いにくくすることができる。   Further, since the reinforcing material 51 having the reinforcing edge portion 54 protects the substantially entire circumference of the surface of the main body portion 12 and the front edge portion 34, the main body portion 12 is firmly protected and reinforced, so that the crime prevention performance Can be further improved. Therefore, even if the bicycle locking device 10 is to be destroyed or cut with the cable cutter C or the like, this is made difficult by the reinforcing member 51 having the reinforcing edge 54, and as a result, the bicycle locking device 10 is less likely to be mischievous or stolen. can do.
