Description

本発明は、走行中に車両のタイヤの空気圧などを検出するタイヤ空気圧検出装置をホイールに取り付けるための取付器具に関する。   The present invention relates to an attachment device for attaching a tire air pressure detection device for detecting the air pressure of a tire of a vehicle during traveling to a wheel.

特許文献１・２には、空気圧センサや無線通信回路や電池などを保護ケース内に収容し、その保護ケースを組み付けたベルトを、車両のタイヤを取り付けるホイールのリムの外周面に凹み形成されたウェルに巻き付けて固定するものが開示されている。   In Patent Documents 1 and 2, a pneumatic sensor, a wireless communication circuit, a battery, and the like are accommodated in a protective case, and a belt assembled with the protective case is formed in a concave shape on the outer peripheral surface of a wheel rim to which a vehicle tire is attached. What is wound around and fixed to a well is disclosed.

特開平７−１４９１２２号公報（段落番号０００２、図５）Japanese Unexamined Patent Publication No. 7-149122 (paragraph number 0002, FIG. 5) 特開２００４−２３７９５１号公報（段落番号００８６、図９）JP 2004-237951 A (paragraph number 0086, FIG. 9)

電池交換などのために保護ケースをホイールから取り外したい場合がある。この場合、特許文献１・２のものでは、まずホイールからタイヤを外して、保護ケースをベルトごとホイールから取り外す必要があり、その手間が煩わしいことになる。   You may want to remove the protective case from the wheel for battery replacement. In this case, in Patent Documents 1 and 2, it is necessary to first remove the tire from the wheel and remove the protective case from the wheel together with the belt, which is troublesome.

これに対して、保護ケースを着脱自在に固定する取付具をベルトに組み付けておき、保護ケースのみを取付具から取り外すことも考えられる。この場合、ベルトをホイールから取り外さなくても済んで、保護ケースの着脱に要する手間が軽減される。   On the other hand, it is also conceivable to attach a fixture for removably fixing the protective case to the belt and remove only the protective case from the fixture. In this case, it is not necessary to remove the belt from the wheel, and the labor required to attach and detach the protective case is reduced.

ところで、タイヤ交換などの際にタイヤのビード部分などが保護ケースに当たると、保護ケースの破損などを招いてしまう。したがって、保護ケースがホイールのウェルからあまり突出しないようにすることが好ましいが、ウェルの横幅は狭くなっているために、ウェル内に収まっている保護ケースを取付具から取り外したり、取り付けたりすることは容易ではない。   By the way, if the bead portion of the tire hits the protective case at the time of exchanging the tire, the protective case is damaged. Therefore, it is preferable that the protective case does not protrude too much from the well of the wheel, but because the width of the well is narrow, the protective case contained in the well should be removed from or attached to the fixture. Is not easy.

また、急ブレーキや急ハンドルなどの操作や路面状態などに応じて、保護ケースには大きな衝撃や振動などが加わる。このため、保護ケースは、取付具に対して容易に着脱できるとともに、がたつくことなくしっかりと取り付けられる必要がある。   In addition, a large impact or vibration is applied to the protective case depending on the operation of the sudden brake or the sudden handle or the road surface condition. For this reason, the protective case can be easily attached to and detached from the fixture and needs to be firmly attached without rattling.

そこで本発明の目的は、保護ケースが取付具に対して容易に着脱できるとともに、がたつくことなくしっかりと取り付けられるタイヤ空気圧検出装置の取付器具を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide a mounting device for a tire pressure detecting device in which a protective case can be easily attached to and detached from a fixture and can be firmly attached without rattling.

本発明は、図２および図３に示すごとく、車両のタイヤを取り付けるホイール５のウェル６に締め付け固定されるベルト２と、このベルト２に組み付けられる取付金具３と、この取付金具３に対して着脱自在に取り付けられる直方体形状の保護ケース１とを含む。取付金具３は、図１に示すごとく、保護ケース１が載る平板状の基板１０と、この基板１０の前後両端からそれぞれ下向きに形成した前後一対の脚部１１・１１と、各脚部１１の下端にそれぞれ形成されてホイール５のウェル６の底面に当接する前後一対の当接部１２・１２とを含む。前後の脚部１１・１１には、図４に示すごとく、ベルト２を通すための通孔１６・１７がそれぞれ形成されている。取付金具３は、基板１０の前後方向の一方の端部から上方へ延びる規制部１５と、基板１０の前後方向の他方の端部から上方へ延びるとともに下方へ押し下げ可能なロック部１９とを設けてあり、ロック部１９と規制部１５とで保護ケース１を前後から挟み込んで保持するとともに、ロック部１９が押し下げられることで、ロック部１９が保護ケース１から外れて保護ケース１が前後方向へ移動可能になる。保護ケース１のケース本体２２の左右両側面の下端部には、図１に示すごとく、嵌合突起２３・２５をそれぞれ突出してあり、取付金具３の基板１０の左右両端部には、保護ケース１の嵌合突起２３・２５がそれぞれ嵌合する係止部２０・２１が上向きに突出してある。基板１０の各係止部２０・２１は、保護ケース１の前後方向へのスライド移動を可能にした状態で、保護ケース１の各嵌合突起２３・２５を嵌合する。   As shown in FIGS. 2 and 3, the present invention provides a belt 2 that is fastened and fixed to a well 6 of a wheel 5 to which a vehicle tire is attached, a mounting bracket 3 that is assembled to the belt 2, and a mounting bracket 3. And a rectangular parallelepiped protective case 1 that is detachably attached. As shown in FIG. 1, the mounting bracket 3 includes a flat board 10 on which the protective case 1 is placed, a pair of front and rear legs 11, 11 formed downward from both front and rear ends of the board 10, and each leg 11. It includes a pair of front and rear contact portions 12 and 12 that are formed at the lower ends and contact the bottom surface of the well 6 of the wheel 5. As shown in FIG. 4, through-holes 16 and 17 for passing the belt 2 are formed in the front and rear legs 11 and 11, respectively. The mounting bracket 3 is provided with a restricting portion 15 that extends upward from one end portion in the front-rear direction of the substrate 10 and a lock portion 19 that extends upward from the other end portion in the front-rear direction of the substrate 10 and can be pushed down. The protective case 1 is sandwiched and held between the lock part 19 and the restricting part 15 and the lock part 19 is pushed down so that the lock part 19 is detached from the protective case 1 and the protective case 1 is moved in the front-rear direction. It becomes movable. As shown in FIG. 1, fitting protrusions 23 and 25 protrude from the lower ends of the left and right side surfaces of the case main body 22 of the protective case 1, respectively. Locking portions 20 and 21 into which the one fitting protrusions 23 and 25 are respectively fitted protrude upward. The respective locking portions 20 and 21 of the substrate 10 are fitted into the fitting protrusions 23 and 25 of the protective case 1 in a state in which the protective case 1 can be slid in the front-rear direction.

具体的には、保護ケース１の左右の嵌合突起２３・２５のうち、一方の嵌合突起２３は、ケース本体２２の一方の側面において前後両端間にわたって設けられ、他方の嵌合突起２５は、ケース本体２２の他方の側面において前後方向に一定間隔をあけて複数個並べて設けられている。取付金具３の基板１０の左右の係止部２０・２１のうち、保護ケース１の一方の嵌合突起２３が嵌合する一方の係止部２０は、その上端部２０ａが基板１０の左右方向の中央側に向けて折れ曲がっていて、図５に示すごとく、一方の嵌合突起２３の上面２３ａに接触するよう形成されている。基板１０の左右の係止部２０・２１のうち、保護ケース１の他方の各嵌合突起２５が嵌合する他方の係止部２１は、図１に示すごとく、前後方向に一定間隔をあけて複数個並べて設けられており、その上端部２１ａが基板１０の左右方向の中央側に向けて折れ曲がっていて、図５に示すごとく、他方の各嵌合突起２５の上面２５ａにそれぞれ接触するよう形成されている。保護ケース１の他方の各嵌合突起２５は、取付金具３に対して保護ケース１を前後方向にずらしたときには、図７に示すごとく、取付金具３の隣り合う他方の係止部２１・２１の間に位置する。   Specifically, of the left and right fitting protrusions 23 and 25 of the protective case 1, one fitting protrusion 23 is provided across the front and rear ends on one side surface of the case body 22, and the other fitting protrusion 25 is A plurality of side surfaces of the case body 22 are provided side by side with a predetermined interval in the front-rear direction. Of the left and right engaging portions 20 and 21 of the board 10 of the mounting bracket 3, one of the engaging portions 20 into which one of the fitting protrusions 23 of the protective case 1 is fitted has an upper end 20 a at the left and right direction of the substrate 10. As shown in FIG. 5, it is formed so as to contact the upper surface 23a of one fitting projection 23. Of the left and right engaging portions 20 and 21 of the substrate 10, the other engaging portion 21 to which the other fitting protrusion 25 of the protective case 1 is fitted is spaced apart in the front-rear direction as shown in FIG. 1. A plurality of the upper end portions 21a are bent toward the central side in the left-right direction of the substrate 10 so as to come into contact with the upper surfaces 25a of the other fitting projections 25 as shown in FIG. Is formed. When the protective case 1 is displaced in the front-rear direction with respect to the mounting bracket 3, the other fitting protrusions 25 of the protective case 1, as shown in FIG. Located between.

より詳しくは、保護ケース１の左右の嵌合突起２３・２５の上面２３ａ・２５ａが、それぞれケース本体２２側が低くなる傾斜面になっており、取付金具３の左右の係止部２０・２１の上端部２０ａ・２１ａが、それぞれ基板１０の左右方向の中央側に向けて斜め下向きに折れ曲がっており、取付金具３の左右の係止部２０・２１の上端部２０ａ・２１ａが、保護ケース１の左右の嵌合突起２３・２５の上面２３ａ・２５ａに押し付けられた状態で面接触するようになっている。   More specifically, the upper surfaces 23a and 25a of the left and right fitting protrusions 23 and 25 of the protective case 1 are inclined surfaces that are lowered on the case body 22 side, and the left and right engaging portions 20 and 21 of the mounting bracket 3 are The upper end portions 20a and 21a are bent obliquely downward toward the center side in the left and right direction of the substrate 10, and the upper end portions 20a and 21a of the left and right engaging portions 20 and 21 of the mounting bracket 3 are Surface contact is made while pressed against the upper surfaces 23a, 25a of the left and right fitting projections 23, 25.

取付金具３のロック部１９は、図４に示すごとく、基板１０の前後方向の中央側が高くなるように基板１０を斜め上向きに切り起こして形成したものであってもよい。   As shown in FIG. 4, the lock portion 19 of the mounting bracket 3 may be formed by cutting and raising the substrate 10 obliquely upward so that the center side in the front-rear direction of the substrate 10 is raised.

本発明では、空気圧センサや電池などを収容した保護ケース１が、ベルト２でホイール５のウェル６に固定された取付金具３に対して着脱自在に取り付けられるので、ホイール５からタイヤを外して、保護ケース１をベルト２ごとホイール５から取り外したり、取り付けたりしなくても済み、その分だけ電池交換などのために保護ケース１を着脱する際の手間を低減できる。   In the present invention, since the protective case 1 containing the air pressure sensor, the battery, and the like is detachably attached to the mounting bracket 3 fixed to the well 6 of the wheel 5 by the belt 2, the tire is removed from the wheel 5, It is not necessary to remove or attach the protective case 1 together with the belt 2 from the wheel 5, and accordingly, it is possible to reduce time and labor when attaching / detaching the protective case 1 for battery replacement or the like.

しかも、取付金具３のロック部１９を押し下げた状態で、取付金具３に対して保護ケース１を前後方向にスライド移動させて、保護ケース１の各嵌合突起２３・２５を取付金具３の各係止部２０・２１にそれぞれ嵌合できるうえ、その嵌合状態でロック部１９と規制部１５とで保護ケース１を前後から挟み込んで保持できる。つまり、ホイール５のウェル６の横幅が小さいために取付金具３の左右横側にスペースの余裕がなくても、保護ケース１を取付金具３に容易に取り付けたり、取り外したりすることができる。その際、保護ケース１の着脱に工具を必要としないので、これによっても保護ケース１を着脱する際の手間を低減できる。   In addition, in a state where the lock portion 19 of the mounting bracket 3 is pressed down, the protective case 1 is slid in the front-rear direction with respect to the mounting bracket 3, and the fitting protrusions 23 and 25 of the protective case 1 are moved to the mounting bracket 3. In addition to being able to be fitted into the locking portions 20 and 21, the protective case 1 can be sandwiched and held between the lock portion 19 and the restricting portion 15 in the fitted state. That is, since the lateral width of the well 6 of the wheel 5 is small, the protective case 1 can be easily attached to or detached from the mounting bracket 3 even if there is no room on the left and right sides of the mounting bracket 3. At this time, since a tool is not required for attaching and detaching the protective case 1, it is possible to reduce the labor for attaching and detaching the protective case 1.

ロック部１９と規制部１５とで保護ケース１の前後方向へのずれ動きが禁止され、保護ケース１の各嵌合突起２３・２５と取付金具３の各係止部２０・２１との嵌合で保護ケース１の上下左右方向へのずれ動きが禁止されるので、保護ケース１が取付金具３にしっかりと固定されて、衝撃や振動などでがたつくことが防止される。   The lock part 19 and the restriction part 15 prevent the protective case 1 from moving in the front-rear direction, and the fitting protrusions 23 and 25 of the protective case 1 and the engaging parts 20 and 21 of the mounting bracket 3 are fitted. Since the movement of the protective case 1 in the up / down / left / right direction is prohibited, the protective case 1 is firmly fixed to the mounting bracket 3 and is prevented from shaking due to impact or vibration.

保護ケース１の他方の各嵌合突起２５が、取付金具３に対して保護ケース１を前後方向にずらしたときには、取付金具３の隣り合う他方の係止部２１・２１の間に位置すると、その前後方向にずらせた状態で、保護ケース１を取付金具３の上方から保護ケース１の一方の嵌合突起２３を取付金具３の一方の係止部２０に嵌め込むとともに、他方の各嵌合突起２５を他方の係止部２１・２１の間に入り込ませたのち、保護ケース１を前後方向にスライド移動させて、他方の各嵌合突起２５と他方の各係止部２１とを嵌合できる。したがって、保護ケース１は、前記ずらした分を前後方向に移動させるだけで取付金具３に取り付けることができ、取付金具３の前後にスペースの余裕があまりなくても、保護ケース１を取付金具３に容易に着脱できる。   When the other fitting protrusions 25 of the protective case 1 are positioned between the other engaging portions 21 and 21 adjacent to the mounting bracket 3 when the protective case 1 is displaced in the front-rear direction with respect to the mounting bracket 3, While the protective case 1 is shifted in the front-rear direction, one fitting protrusion 23 of the protective case 1 is fitted into one locking portion 20 of the mounting bracket 3 from above the mounting bracket 3 and each of the other fittings is fitted. After the protrusion 25 is inserted between the other locking portions 21, 21, the protective case 1 is slid in the front-rear direction, and the other fitting protrusion 25 and the other locking portion 21 are fitted. it can. Therefore, the protective case 1 can be attached to the mounting bracket 3 simply by moving the shifted amount in the front-rear direction, and the protective case 1 can be attached to the mounting bracket 3 even if there is not enough space before and after the mounting bracket 3. Easy to attach and detach.

保護ケース１の各嵌合突起２３・２５の上面２３ａ・２５ａが、ケース本体２２側が低くなる傾斜面であり、それに合わせて取付金具３の各係止部２０・２１の上端部２０ａ・２１ａが斜め下向きに折れ曲がって、前記係止部２０・２１の上端部２０ａ・２１ａが前記嵌合突起２３・２５の上面２３ａ・２５ａに押し付けられた状態で面接触すると、取付金具３の係止部２０・２１の上端部２０ａ・２１ａでも保護ケース１の嵌合突起２３・２５をしっかりと保持できて、保護ケース１が取付金具３に対して左右や上下にずれ動くことを好適に防止できる。さらに取付金具３の係止部２０・２１の上端部２０ａ・２１ａと、保護ケース１の嵌合突起２３・２５の上面２３ａ・２５ａとが面接触することで、保護ケース１がずれ動いた際の摩擦で、保護ケース１の嵌合突起２３・２５が取付金具３の係止部２０・２１によって削られることを低減できる。   The upper surfaces 23a and 25a of the fitting projections 23 and 25 of the protective case 1 are inclined surfaces that are lowered on the case body 22 side, and the upper end portions 20a and 21a of the locking portions 20 and 21 of the mounting bracket 3 are accordingly adjusted. When the upper end portions 20a and 21a of the engaging portions 20 and 21 are bent obliquely downward and come into surface contact with the upper surfaces 23a and 25a of the fitting projections 23 and 25, the engaging portions 20 of the mounting bracket 3 are brought into contact with each other. The upper end portions 20a and 21a of the 21 can firmly hold the fitting protrusions 23 and 25 of the protective case 1 and can suitably prevent the protective case 1 from moving to the left and right or up and down with respect to the mounting bracket 3. Further, when the upper end portions 20a and 21a of the locking portions 20 and 21 of the mounting bracket 3 and the upper surfaces 23a and 25a of the fitting protrusions 23 and 25 of the protective case 1 are in surface contact, the protective case 1 is displaced. It is possible to reduce the fact that the fitting protrusions 23 and 25 of the protective case 1 are scraped by the locking portions 20 and 21 of the mounting bracket 3 due to the friction.

取付金具３のロック部１９が、基板１０を斜め上向きに切り起こして形成したものであると、ロック部１９を別部材で形成する場合よりも容易に形成できる。   When the lock portion 19 of the mounting bracket 3 is formed by cutting and raising the substrate 10 obliquely upward, it can be formed more easily than when the lock portion 19 is formed by a separate member.

図面は、本発明が対象とするタイヤ空気圧検出装置の取付器具の実施例を示しており、図１および図２に示すごとく、空気圧センサや無線通信回路や電池などを収容した直方体形状の保護ケース１と、金属ベルト２に組み付けられる取付金具３とを含む。保護ケース１は、取付金具３に対して着脱自在に取り付けられる。金属ベルト２は、ステンレス鋼などからなり、図３に示すごとく、車両のタイヤを取り付けるホイール５のウェル６に巻き付けられた状態で締め付け固定される。ウェル６は、ホイール５のリム７の外周に凹み形成される。   The drawings show an embodiment of a mounting device for a tire air pressure detecting device targeted by the present invention, and as shown in FIGS. 1 and 2, a rectangular parallelepiped protective case containing a pneumatic sensor, a wireless communication circuit, a battery, and the like. 1 and a mounting bracket 3 to be assembled to the metal belt 2. The protective case 1 is detachably attached to the mounting bracket 3. The metal belt 2 is made of stainless steel or the like, and is fastened and fixed in a state of being wound around a well 6 of a wheel 5 to which a vehicle tire is attached, as shown in FIG. The well 6 is formed as a recess on the outer periphery of the rim 7 of the wheel 5.

取付金具３は、ばね用ステンレス鋼製の１枚の平板に対してプレス加工などを行うことで形成されており、図１および図４に示すごとく、保護ケース１が載る平板状の基板１０と、基板１０の前後両端からそれぞれ下向きに形成した前後一対の脚部１１・１１と、各脚部１１の下端からそれぞれ外向きに形成した前後一対の当接部１２・１２とを含む。各当接部１２は、ホイール５のウェル６の底面に当接するようになっており、ウェル６の底面との接触面積を確保するために前後方向に傾斜してある。   The mounting bracket 3 is formed by pressing or the like on one flat plate made of spring stainless steel. As shown in FIGS. 1 and 4, a flat substrate 10 on which the protective case 1 is placed, And a pair of front and rear legs 11, 11 formed downward from both front and rear ends of the substrate 10, and a pair of front and rear contact parts 12, 12 formed outward from the lower ends of the legs 11. Each contact portion 12 is in contact with the bottom surface of the well 6 of the wheel 5, and is inclined in the front-rear direction in order to ensure a contact area with the bottom surface of the well 6.

取付金具３は、基板１０の前後方向の一方の端部（図４の右側）から上方へ延びる規制部１５と、基板１０の前後方向の他方の端部（図４の左側）から上方へ延びるとともに下方へ押し下げ可能なロック部１９とを設けてある。つまり、規制部１５は、一方の脚部１１（図４の右側）の左右方向の中央部を上向きに切り起こすことで形成してある。この切り起こしに伴って一方の脚部１１の左右方向の中央部には、金属ベルト２を通すための第１通孔１６が形成される。   The mounting bracket 3 extends upward from one end portion (right side in FIG. 4) in the front-rear direction of the substrate 10 and upward from the other end portion (left side in FIG. 4) in the front-rear direction of the substrate 10. In addition, a lock portion 19 that can be pushed down is provided. That is, the restricting portion 15 is formed by raising the left-right central portion of one leg portion 11 (right side in FIG. 4) upward. Along with this cutting and raising, a first through hole 16 through which the metal belt 2 is passed is formed in the center portion in the left-right direction of one leg portion 11.

他方の脚部１１（図４の左側）の左右方向の中央部には、第１通孔１６に対面する第２通孔１７が形成される。金属ベルト２は、第１通孔１６と第２通孔１７とを通った状態でホイール５のウェル６に巻き付けられる。   A second through hole 17 that faces the first through hole 16 is formed at the center in the left-right direction of the other leg 11 (left side in FIG. 4). The metal belt 2 is wound around the well 6 of the wheel 5 while passing through the first through hole 16 and the second through hole 17.

ロック部１９は、基板１０において他方の脚部１１側の端部を斜め上向きに切り起こすことで形成されており、基板１０の前後方向の中央側が高くなっている。ロック部１９の先端と規制部１５とで、保護ケース１を前後から挟み込んで保持する（図４の状態）。ロック部１９を押し下げることで、ロック部１９が保護ケース１から外れて保護ケース１が前後方向へ移動可能になる。   The lock portion 19 is formed by cutting and raising the end portion on the other leg portion 11 side of the substrate 10 obliquely upward, and the center side in the front-rear direction of the substrate 10 is higher. The protective case 1 is sandwiched and held between the front end of the lock portion 19 and the regulating portion 15 (state shown in FIG. 4). By depressing the lock portion 19, the lock portion 19 is detached from the protective case 1, and the protective case 1 can be moved in the front-rear direction.

図１および図５に示すごとく、基板１０の左右両端部のうち、一方の端部（図５では左側）から上向きに第１係止部２０が突出形成される。第１係止部２０は、前後方向に長くなるよう形成されており、第１係止部２０の上端部２０ａが、基板１０の左右方向の中央側に向けて斜め下向きに折れ曲がっている。   As shown in FIGS. 1 and 5, a first locking portion 20 is formed so as to protrude upward from one end portion (left side in FIG. 5) of the left and right end portions of the substrate 10. The first locking portion 20 is formed to be long in the front-rear direction, and the upper end portion 20 a of the first locking portion 20 is bent obliquely downward toward the center side in the left-right direction of the substrate 10.

Thus, when the first fitting protrusion 23 is fitted to the first locking portion 20 of the mounting bracket 3, the upper end portion 20 a of the first locking portion 20 of the mounting bracket 3 is fitted to the first fitting of the protective case 1. Surface contact is made while pressed against the upper surface 23 a of the protrusion 23.

各第２嵌合突起２５は、保護ケース１を取付金具３に取り付けたときには、取付金具３の各第２係止部２１にそれぞれ嵌合する。つまり、各第２嵌合突起２５は、保護ケース１の前後方向へのスライド移動を可能にした状態で、取付金具３の各第２係止部２１にそれぞれ嵌合する。各第２嵌合突起２５の前後方向の長さは、隣り合う第２係止部２１・２１の間隔よりも小さくなっていて、各第２嵌合突起２５は、取付金具３に対して保護ケース１を前後方向にずらしたときには、取付金具３の隣り合う第２係止部２１・２１の間に位置する。   Each of the second fitting protrusions 25 is fitted into each of the second locking portions 21 of the mounting bracket 3 when the protective case 1 is mounted on the mounting bracket 3. That is, each second fitting protrusion 25 is fitted to each second locking portion 21 of the mounting bracket 3 in a state in which the sliding movement of the protective case 1 in the front-rear direction is enabled. The length in the front-rear direction of each second fitting protrusion 25 is smaller than the interval between the adjacent second locking portions 21 and 21, and each second fitting protrusion 25 protects the mounting bracket 3. When the case 1 is shifted in the front-rear direction, the case 1 is positioned between the adjacent second locking portions 21 and 21 of the mounting bracket 3.

各第２嵌合突起２５の上面２５ａは、図５に示すごとく、ケース本体２２側が低くなる傾斜面になっていて、取付金具３の各第２係止部２１の上端部２１ａが、各第２嵌合突起２５の上面２５ａより僅かに大きく下向きに傾斜している。これにより、各第２嵌合突起２５が、取付金具３の各第２係止部２１にそれぞれ嵌合したときには、先の第１係止部２０と同様に各第２係止部２１の上端部２１ａが、保護ケース１の各第２嵌合突起２５の上面２５ａに押し付けられた状態で面接触する。各第２嵌合突起２５の上面２５ａの縁は面取りされている。   As shown in FIG. 5, the upper surface 25 a of each second fitting protrusion 25 has an inclined surface that is lowered on the case body 22 side, and the upper end portion 21 a of each second locking portion 21 of the mounting bracket 3 2 It is slightly larger than the upper surface 25a of the fitting protrusion 25 and is inclined downward. Thereby, when each 2nd fitting protrusion 25 is each fitted in each 2nd latching | locking part 21 of the attachment metal fitting 3, the upper end of each 2nd latching | locking part 21 similarly to the previous 1st latching | locking part 20 is carried out. The part 21a is in surface contact with the upper surface 25a of each second fitting protrusion 25 of the protective case 1 while being pressed. The edge of the upper surface 25a of each second fitting protrusion 25 is chamfered.

次に、タイヤ空気圧検出装置の取付器具の使用要領を説明する。取付金具３に保護ケース１を取り付けるときには、図６に示すごとく、まず保護ケース１を第１嵌合突起２３側が低くなる斜め姿勢にして、第１嵌合突起２３の上端側を取付金具３の第１係止部２０に嵌め込む。この際、平面視で保護ケース１の各第２嵌合突起２５が、取付金具３の各第２係止部２１の間に位置するように、保護ケース１を取付金具３の後ろ側（規制部１５から離れる方向）にずらせておく。   Next, how to use the mounting device of the tire pressure detecting device will be described. When attaching the protective case 1 to the mounting bracket 3, as shown in FIG. 6, first, the protective case 1 is placed in an oblique posture in which the first fitting projection 23 side is lowered, and the upper end side of the first fitting projection 23 is placed on the mounting bracket 3. Fit into the first locking portion 20. At this time, the protective case 1 is placed behind the mounting bracket 3 (regulation) so that the second fitting protrusions 25 of the protective case 1 are positioned between the second locking portions 21 of the mounting bracket 3 in plan view. In the direction away from the part 15).

この状態で、保護ケース１の第２嵌合突起２５側を降ろすことで、第１嵌合突起２３が取付金具３の第１係止部２０に嵌合し、また各第２嵌合突起２５が、図７（ａ）・（ｂ）に示すごとく、取付金具３の上方から隣り合う第２係止部２１・２１の間に入り込む。この際、保護ケース１の下面が、取付金具３のロック部１９の上端に当たってロック部１９を押し下げる。   In this state, by lowering the second fitting projection 25 side of the protective case 1, the first fitting projection 23 is fitted into the first locking portion 20 of the mounting bracket 3, and each second fitting projection 25 However, as shown in FIGS. 7A and 7B, it enters between the second locking portions 21 and 21 adjacent to each other from above the mounting bracket 3. At this time, the lower surface of the protective case 1 hits the upper end of the lock portion 19 of the mounting bracket 3 and pushes down the lock portion 19.

次いで、保護ケース１を前側（規制部１５に近づく方向）へスライド移動させることで、第１嵌合突起２３が取付金具３の第１係止部２０に嵌合した状態のまま、保護ケース１の各第２嵌合突起２５が取付金具３の各第２係止部２１に嵌合する（図５参照）。このとき、保護ケース１の前面が、取付金具３の規制部１５に当たって前方への移動が規制されるとともに、保護ケース１が取付金具３のロック部１９から外れて、ロック部１９が弾性復元力で斜め上向きの姿勢に復帰する（図４参照）。   Next, the protective case 1 remains in a state in which the first fitting protrusion 23 is fitted to the first locking portion 20 of the mounting bracket 3 by sliding the protective case 1 to the front side (direction approaching the restricting portion 15). Each 2nd fitting protrusion 25 fits to each 2nd latching | locking part 21 of the attachment metal fitting 3 (refer FIG. 5). At this time, the front surface of the protective case 1 hits the restricting portion 15 of the mounting bracket 3 and the forward movement is restricted, and the protective case 1 is disengaged from the lock portion 19 of the mounting bracket 3, so that the lock portion 19 is elastically restored. To return to an obliquely upward posture (see FIG. 4).

これにより、保護ケース１の前後が、ロック部１９の先端と規制部１５とで挟み込まれて、保護ケース１は、前後方向へのずれ動きが禁止される。そのうえで、保護ケース１の第１嵌合突起２３が取付金具３の第１係止部２０に嵌合し、保護ケース１の各第２嵌合突起２５が取付金具３の各第２係止部２１に嵌合しているので、保護ケース１は、取付金具３にしっかりと固定される。   Thereby, the front and rear of the protective case 1 are sandwiched between the front end of the lock portion 19 and the restricting portion 15, and the protective case 1 is prohibited from shifting in the front-rear direction. In addition, the first fitting protrusions 23 of the protective case 1 are fitted into the first locking portions 20 of the mounting bracket 3, and the second fitting protrusions 25 of the protective case 1 are respectively connected to the second locking portions of the mounting bracket 3. 21, the protective case 1 is firmly fixed to the mounting bracket 3.

In this state, the protective case 1 is pushed rearward and slid until each second fitting protrusion 25 is positioned between the second locking portions 21 and 21 of the mounting bracket 3 in plan view. 2 fitting protrusion 25 remove | deviates from each 2nd latching | locking part 21 of the attachment metal fitting 3 (refer FIG. 7).

次いで、保護ケース１の第２嵌合突起２５側を持ち上げて保護ケース１を斜めにすることで、保護ケース１の第１嵌合突起２３が取付金具３の第１係止部２０から外れ（図６参照）、保護ケース１が取付金具３から取り外される。   Next, by lifting the second fitting protrusion 25 side of the protective case 1 and making the protective case 1 slant, the first fitting protrusion 23 of the protective case 1 comes off from the first locking portion 20 of the mounting bracket 3 ( The protective case 1 is removed from the mounting bracket 3 (see FIG. 6).

なお、取付金具３の規制部１５および各第２係止部２１は、保護ケース１を取付金具３に取り付ける前の状態で、それぞれ基板１０の中央側に若干傾いており、保護ケース１を取付金具３に取り付けたときには、保護ケース１が規制部１５および各第２係止部２１でそれぞれ押されて、保護ケース１のがたつきが抑制される。   The restricting portion 15 and each second locking portion 21 of the mounting bracket 3 are slightly inclined toward the center side of the substrate 10 before the protective case 1 is attached to the mounting bracket 3, and the protective case 1 is attached. When attached to the metal fitting 3, the protective case 1 is pushed by the restricting portion 15 and the second locking portions 21, respectively, and rattling of the protective case 1 is suppressed.

保護ケース１を水平姿勢にして、保護ケース１の第１嵌合突起２３と第２嵌合突起２５とを、取付金具３の後方から第１係止部２０と第２係止部２１とに同時に差し入れて嵌合させてもよい。この場合、保護ケース１の第２嵌合突起２５と、取付金具３の第２係止部２１とは、それぞれ前後に長い１個の第２嵌合突起２５と、１個の第２係止部２１とであってもよい。ロック部１９は、ばねなどで押し上げ付勢されるボタン形状のものなどでもよい。   With the protective case 1 in a horizontal posture, the first fitting protrusion 23 and the second fitting protrusion 25 of the protective case 1 are connected to the first locking part 20 and the second locking part 21 from the rear of the mounting bracket 3. You may insert and fit simultaneously.
