Description

【０００１】
【発明の属する技術分野】
この発明は、パーキングブレーキ装置のカバー取付構造に関するものである。
【０００２】
【従来の技術】
自動車のコンソール等には、パーキングブレーキ装置が備えられている。この種のパーキングブレーキ装置は、下部を中心にして引起こし回動可能に支持されたレバーを備え、そのレバーを上方へ引き起こすことにより、その操作力がケーブルを介して車輪のブレーキ機構に伝達されるようになっている（類似技術として、特開平９−６６８１９号公報参照）。
【０００３】
レバーには、該レバーと一体的に回動するカバーが取付けられている。カバーは、レバーに相応した筒形状をしており、レバーの前端部側から被せて取付けられる。カバーの上部開口は狭く、レバーに被せたことにより、カバーの上部は概ね位置が決まる。カバーの左右の側面部の後部には、ビス孔が形成され、レバーの側面の対応位置には、ナット部が設けられている。そして、ビス孔とナット部とを位置合わせした後に、両者をビスで締結することにより、カバーをレバーに固定するようになっている。
【０００４】
【発明が解決しようとする課題】
しかしながら、このような従来の技術にあっては、カバーをレバーに被せる工程の他に、ビス孔とナット部とを位置合わせする工程と、両者をビスにより締結する工程の２工程が必要になるため、カバーの取付作業の能率が悪い。
【０００５】
この発明は、このような従来の技術に着目してなされたものであり、カバーの取付作業の能率を向上させることができるパーキングブレーキ装置のカバー取付構造を提供するものである。
【０００６】
【課題を解決するための手段】
請求項１記載の発明は、下部を中心にして引起こし回動可能に支持されたレバーに、該レバーに相応した筒形状のカバーを、レバーの前端部側から被せて取付けるパーキングブレーキ装置のカバー取付構造であって、前記カバーの前部内面に、レバーの対応部に形成された受部に対して上側から係合する突起部を形成し、レバーの受部よりも後方位置に左右両側へ突出するピンを形成すると共に、カバーの左右側面部の下端付近であって、カバーの前部をレバーに押付けた状態で且つ受部に係合した突起部を中心にしてカバーを回動させながら取付ける際におけるピンのカバーに対する略円弧軌跡上に、ピンが係入する取付孔を形成した。
【０００７】
請求項１記載の発明によれば、カバーをレバーの前端部から被せた後は、カバーの前部をレバーに押付けた状態で、受部に係合した突起部を中心にカバーを回動させるだけで、レバーのピンと、カバーの取付孔との位置が自然と合うため、その後に、取付孔の中にピンを係入させる作業を行うだけで良い。従来に比べ、位置合わせする作業が不要になるため、その分、カバーの取付作業の能率が向上する。
【０００８】
請求項２記載の発明は、ピンの上面に、カバーの左右側面部の下端と当接して、該下端を左右へ開く方向へガイドする傾斜面を形成した。
【０００９】
請求項２記載の発明によれば、前項の効果に加えて、ピンの上面に傾斜面を形成したため、カバーの下端がピンに当接して、ピンと取付孔との位置合わせがなされた状態から連続して、更にカバーを回動させることにより、カバーの下端が左右へ開いて、そのまま取付孔の中にピンを係入させることができる。従って、位置合わせ作業だけでなく、その後の締結作業も不要になるため、カバーの取付作業の能率が更に向上する。
【００１０】
請求項３記載の発明は、カバーの左右側面部の下端に、ピンと当接して、該下端を左右へ開く方向へガイドする傾斜面を形成した。
【００１１】
請求項３記載の発明によれば、カバーの左右側面部の下端に傾斜面を形成したため、カバーの下端がピンに当接して、ピンと取付孔との位置合わせがなされた状態から連続して、更にカバーを回動させることにより、カバーの下端が左右へ開いて、そのまま取付孔の中にピンを係入させることができる。従って、前項の場合と同様に、位置合わせ作業だけでなく、その後の締結作業も不要になるため、カバーの取付作業の能率が更に向上する。
【００１２】
請求項４記載の発明は、カバーの左右側面部の下端における取付孔よりも後側部分が、ピンと当接した状態で、後方に下がった傾斜状態になっている。
【００１３】
請求項４記載の発明によれば、受部に係合した突起部を中心にカバーを回動させる際に、カバーの前部がレバーに対してしっかりと押付けられた状態になっていなくても、カバーの左右側面部の下端における取付孔よりも後側部分が、後方に下がった傾斜状態になっているため、カバーの下端がピンに対して上側から当接した際に、カバー全体を後方へ移動させようとする力が作用し、カバーの前部がレバーに対して押付けられる。従って、カバーの取付孔がピンの略円弧軌跡上に合致した状態となり、ピンと取付孔との位置が合う。
【００１４】
【発明の実施の形態】
以下、この発明の好適な実施形態を図面に基づいて説明する。
【００１５】
図１〜図５は、この発明の第１実施形態を示す図である。図１中の符号１は、コンソールを示している。コンソール１の内部には、車体に固定されたベース２が設けられ、このベース２に、図示しない周知のパーキングブレーキのレバー３の下部が引起こし回動可能に支持されている。レバー３の前側は、コンソール１の上面に形成された図示せぬ開口から車室内側へ突出している。
【００１６】
レバー３の前側には、合成樹脂製のグリップ４が取付けられ、後側には同じく合成樹脂製のカバー５が取付けられている。グリップ４の前端には、引き起こしたレバー３を元に戻す際の解除ボタン６が設けられている。グリップ４は、レバー３の前側に被せるだけで取付けが完了する既知の構造になっており、説明を省略する。
【００１７】
カバー５は、レバー３の後側を包む筒形状をしている。このカバー５は、レバー３の後側に相応して、左右に対向した側面部を有する幅の狭い扁平筒形状をしており、側面視で下方が広がった形状になっているが、上側の開口７も前後方向に広く形成されている。このカバー５は、グリップ４を取付ける前に、レバー３の前端側から被せて取付けられる。
【００１８】
このカバー５の前部内面には、突起部８が一体的に形成されている。また、レバー３の対応部には、前方へ突出した受部９が一体的に形成されている。カバー５の突起部８は、レバー３の受部９に対して上側から係合することができる。また、受部９の方が、突起部８よりも、若干突出量が大きく、両者が互いに係合した状態で、受部９の先端がカバー５の前部内面に当接するが、突起部８の先端はレバー３に達しない。そのため、カバー５とレバー３とが前後方向で強干渉しても、突起部８の破損が防止される。
【００１９】
一方、レバー３の後端には、左右両側へ突出するピン１０がそれぞれ形成されている。このピン１０は、円柱形状で、その上面及びその周辺には、ピン１０の根本から先端にかけて傾斜面１１が形成されている。
【００２０】
そして、カバー５の左右側面部の下端１２付近には、前記ピン１０を係入する取付孔１３がそれぞれ形成されている。また、カバー５の下端１２は、取付孔１３の辺りが、後側に下がった傾斜状態になっている。このカバー５の下端１２の傾斜状態は、取付孔１３よりも後側部分Ｓ（図４参照）に形成されていることに意味があり、取付孔１３よりも前側は傾斜していなくても良い。
【００２１】
カバー５をレバー３に取付ける時は、まずカバー５をレバー３の前端部側から被せ、カバー５の前部をレバー３に押付けた状態で、カバー５の突起部８を、レバー３の受部９に対して上側から係合させる。突起部８と受部９とが係合した後は、カバー５は受部９に係合した突起部８を中心にして回動しながらレバー３に対して取付けられる。この時に、カバー５の取付孔１３の位置が、レバー３のピン１０に対して正確に合致するように、取付孔１３の位置は、受部９に係合した突起部８を中心にしてカバー５を回動させながら取付ける際におけるピン１０のカバー５に対する円弧軌跡Ｅ上に規定されている。従って、カバー５をそのまま回動させて、カバー５の下端１２をピン１０に当接させるだけで、ピン１０と取付孔１３との位置が合うようになっている。
【００２２】
しかも、ピン１０の上面に傾斜面１１が形成されているため、カバー５の下端１２がピン１０に当接した状態から連続して、カバー５を更に回動させることにより、カバー５の下端１２が左右へ開いて、そのまま取付孔１３の中にピン１０を係入させることができる。このように、カバー５を、受部９に係合した突起部８を中心にして回動させながら取付けるだけで、取付孔１３とピン１０との位置合わせ作業、ならびに両者の締結作業の両方を行うことができるため、従来に比べ、カバー５の取付作業の能率が向上する。
【００２３】
更に、カバー５の下端１２における取付孔１３よりも後側部分Ｓが、後方に下がった傾斜状態になっているため、カバー５を回動させながら取付ける際に、万一、カバー５の前部がレバー３に対してしっかりと押付けられた状態になっていなくても、カバー５の下端１２がピン１０に対して上側から当接した際に、カバー５全体を後方へ移動させようとする力Ｆが作用し（図４参照）、カバー５の前部がレバー３に対して押付けられる。従って、カバー５の取付孔１３がピン１０の円弧軌跡Ｅ上に合致した状態となり、ピン１０と取付孔１３との位置が合い易い。
【００２４】
図６は、この発明の第２実施形態を示す図である。この実施形態では、ピン１４の上面に、先の実施形態のような傾斜面を設けず、その代わりに、カバー１５の左右側面部の下端１６に、ピン１４と当接して、該下端１６を左右へ開く方向へガイドする傾斜面１７を形成した。この傾斜面１７は、カバー１５の板厚よりも大きな幅でカバー１５の内側に延びており、取付孔１８内にピン１４が係入した後に、カバー１５が再び上方へ外れるのを防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a cover mounting structure for a parking brake device.
[0002]
[Prior art]
A parking brake device is provided in an automobile console or the like. This type of parking brake device includes a lever that is raised and pivoted around the lower part, and the lever is raised upward to transmit the operating force to the wheel brake mechanism via a cable. (For a similar technique, see JP-A-9-66819).
[0003]
A cover that rotates integrally with the lever is attached to the lever. The cover has a cylindrical shape corresponding to the lever, and is attached so as to be covered from the front end side of the lever. The upper opening of the cover is narrow and the position of the upper part of the cover is generally determined by covering the lever. Screw holes are formed in the rear portions of the left and right side portions of the cover, and nut portions are provided at corresponding positions on the side surfaces of the lever. And after aligning a screw hole and a nut part, both are fastened with a screw, and a cover is fixed to a lever.
[0004]
[Problems to be solved by the invention]
However, in such a conventional technique, in addition to the step of covering the cover with the lever, two steps of aligning the screw hole and the nut portion and fastening the two with screws are required. Therefore, the efficiency of the cover mounting work is poor.
[0005]
The present invention has been made paying attention to such a conventional technique, and provides a cover mounting structure for a parking brake device capable of improving the efficiency of cover mounting work.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a parking brake device cover in which a cylindrical cover corresponding to the lever is attached to a lever that is raised and pivoted about a lower portion and is supported from the front end side of the lever. In the mounting structure, a protrusion is formed on the inner surface of the front part of the cover from the upper side with respect to the receiving part formed on the corresponding part of the lever, and the rear side of the lever receiving part is on the left and right sides. While forming a protruding pin and rotating the cover around the protrusion engaged with the receiving part, with the front part of the cover pressed against the lever, near the lower ends of the left and right side surfaces of the cover A mounting hole into which the pin is engaged is formed on a substantially arc locus with respect to the cover of the pin when mounting.
[0007]
According to the first aspect of the present invention, after the cover is covered from the front end portion of the lever, the cover is rotated around the protruding portion engaged with the receiving portion while the front portion of the cover is pressed against the lever. Therefore, since the positions of the lever pin and the cover mounting hole naturally match, it is only necessary to engage the pin into the mounting hole thereafter. Compared with the prior art, the alignment work is unnecessary, and the efficiency of the cover mounting work is improved accordingly.
[0008]
According to the second aspect of the present invention, an inclined surface is formed on the upper surface of the pin so as to contact the lower ends of the left and right side portions of the cover and guide the lower end in a direction to open left and right.
[0009]
According to the invention described in claim 2, in addition to the effect of the preceding paragraph, since the inclined surface is formed on the upper surface of the pin, the lower end of the cover is in contact with the pin, and the pin and the mounting hole are continuously aligned. Then, by further rotating the cover, the lower end of the cover opens to the left and right, and the pin can be engaged in the mounting hole as it is. Therefore, not only the alignment work but also the subsequent fastening work becomes unnecessary, and the efficiency of the cover attaching work is further improved.
[0010]
According to a third aspect of the present invention, an inclined surface is formed at the lower end of the left and right side surfaces of the cover so as to contact the pin and guide the lower end to the left and right direction.
[0011]
According to the invention of claim 3, since the inclined surface is formed at the lower ends of the left and right side portions of the cover, the lower end of the cover is in contact with the pin and continuously from the state where the pin and the mounting hole are aligned, Further, by rotating the cover, the lower end of the cover opens to the left and right, and the pin can be engaged in the mounting hole as it is. Therefore, as in the case of the previous section, not only the alignment work but also the subsequent fastening work becomes unnecessary, and the efficiency of the cover mounting work is further improved.
[0012]
In a fourth aspect of the present invention, the rear portion of the cover at the lower end of the left and right side portions of the cover is in an inclined state where the rear portion is in contact with the pin and is lowered rearward.
[0013]
According to the fourth aspect of the present invention, when the cover is rotated around the protrusion engaged with the receiving portion, the front portion of the cover is not firmly pressed against the lever. Since the rear part of the cover at the lower end of the left and right side surfaces of the cover is inclined to the rear, the entire cover is moved backward when the lower end of the cover comes into contact with the pin from above. A force to move the cover acts on the front portion of the cover against the lever. Therefore, the cover mounting hole is in a state of being aligned with the substantially arc locus of the pin, and the pin and the mounting hole are aligned.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings.
[0015]
1 to 5 are views showing a first embodiment of the present invention. Reference numeral 1 in FIG. 1 indicates a console. Inside the console 1, a base 2 fixed to the vehicle body is provided, and a lower portion of a lever 3 of a well-known parking brake (not shown) is raised and supported on the base 2 so as to be rotatable. The front side of the lever 3 protrudes from the opening (not shown) formed on the upper surface of the console 1 to the vehicle interior side.
[0016]
A synthetic resin grip 4 is attached to the front side of the lever 3, and a synthetic resin cover 5 is also attached to the rear side. A release button 6 is provided at the front end of the grip 4 to return the lever 3 that has been raised. The grip 4 has a known structure that can be attached simply by covering the front side of the lever 3, and the description thereof will be omitted.
[0017]
The cover 5 has a cylindrical shape that wraps around the rear side of the lever 3. The cover 5 has a narrow flat cylindrical shape having side portions facing left and right, corresponding to the rear side of the lever 3, and has a shape in which the lower side is widened in a side view. The opening 7 is also widely formed in the front-rear direction. The cover 5 is attached so as to be covered from the front end side of the lever 3 before the grip 4 is attached.
[0018]
A projection 8 is integrally formed on the inner surface of the front portion of the cover 5. In addition, a receiving portion 9 that protrudes forward is formed integrally with the corresponding portion of the lever 3. The protruding portion 8 of the cover 5 can be engaged with the receiving portion 9 of the lever 3 from above. Further, the receiving portion 9 has a slightly larger protruding amount than the protruding portion 8, and the tip of the receiving portion 9 abuts against the inner surface of the front portion of the cover 5 in a state where both are engaged with each other. Does not reach the lever 3. Therefore, even if the cover 5 and the lever 3 strongly interfere with each other in the front-rear direction, the protrusion 8 is prevented from being damaged.
[0019]
On the other hand, pins 10 are formed at the rear end of the lever 3 so as to protrude to the left and right sides. The pin 10 has a cylindrical shape, and an inclined surface 11 is formed on the upper surface and the periphery thereof from the root to the tip of the pin 10.
[0020]
And the attachment hole 13 which engages with the said pin 10 is formed in the vicinity of the lower end 12 of the right-and-left side part of the cover 5, respectively. Further, the lower end 12 of the cover 5 is in an inclined state in which the vicinity of the attachment hole 13 is lowered to the rear side. The inclined state of the lower end 12 of the cover 5 has a meaning that it is formed in the rear portion S (see FIG. 4) with respect to the attachment hole 13, and the front side of the attachment hole 13 may not be inclined. .
[0021]
When the cover 5 is attached to the lever 3, the cover 5 is first covered from the front end side of the lever 3, and the projection 8 of the cover 5 is inserted into the receiving portion of the lever 3 while the front portion of the cover 5 is pressed against the lever 3. 9 is engaged from above. After the protruding portion 8 and the receiving portion 9 are engaged, the cover 5 is attached to the lever 3 while rotating around the protruding portion 8 engaged with the receiving portion 9. At this time, the position of the mounting hole 13 is centered on the protrusion 8 engaged with the receiving portion 9 so that the position of the mounting hole 13 of the cover 5 accurately matches the pin 10 of the lever 3. It is defined on an arc locus E with respect to the cover 5 of the pin 10 when mounting while rotating 5. Therefore, the position of the pin 10 and the mounting hole 13 can be matched by simply rotating the cover 5 and bringing the lower end 12 of the cover 5 into contact with the pin 10.
[0022]
In addition, since the inclined surface 11 is formed on the upper surface of the pin 10, the lower end 12 of the cover 5 is further rotated by continuously rotating the cover 5 from the state in which the lower end 12 of the cover 5 is in contact with the pin 10. Open to the left and right, and the pin 10 can be engaged in the mounting hole 13 as it is. As described above, the cover 5 is simply mounted while being rotated around the protrusion 8 engaged with the receiving portion 9, so that both the alignment work of the mounting hole 13 and the pin 10 and the fastening work of both are performed. Since it can be performed, the efficiency of the mounting work of the cover 5 is improved as compared with the conventional case.
[0023]
Furthermore, since the rear portion S of the lower end 12 of the cover 5 is inclined downward from the mounting hole 13, when the cover 5 is mounted while being rotated, the front portion of the cover 5 should be Even when the lever 3 is not firmly pressed against the lever 3, when the lower end 12 of the cover 5 comes into contact with the pin 10 from the upper side, the force to move the entire cover 5 rearward F acts (see FIG. 4), and the front portion of the cover 5 is pressed against the lever 3. Therefore, the mounting hole 13 of the cover 5 is aligned with the arc locus E of the pin 10, and the positions of the pin 10 and the mounting hole 13 are easily matched.
[0024]
FIG. 6 is a diagram showing a second embodiment of the present invention. In this embodiment, the upper surface of the pin 14 is not provided with the inclined surface as in the previous embodiment, and instead, the lower end 16 of the cover 15 is in contact with the pin 14 at the lower end 16 of the left and right side surfaces, and the lower end 16 is An inclined surface 17 is formed to guide in the direction to open to the left and right. The inclined surface 17 extends to the inside of the cover 15 with a width larger than the plate thickness of the cover 15, and prevents the cover 15 from coming off again after the pin 14 is engaged in the mounting hole 18. Can do.
