Description

本発明は、車両用グローブボックス等に設けられるロック装置に関する。   The present invention relates to a locking device provided in a vehicle glove box or the like.

特開２００５−１０４１９２号公報は、固定部材に対して開閉動可能な可動部材を固定部材に対して閉位置にロックするロック装置を開示している。ロック装置は、可動部材に左右方向に延びて設けられる第１、第２のロッドと、第１、第２のロッドに連結され第１、第２のロッドを互いに反対方向に同期させるギアと、固定部材に設けられ第１、第２のロッドの先端部が出入りするロック受け部と、を備えている。   Japanese Patent Laying-Open No. 2005-104192 discloses a lock device that locks a movable member that can be opened and closed with respect to a fixed member in a closed position with respect to the fixed member. The locking device includes first and second rods that extend in the left-right direction on the movable member, and a gear that is coupled to the first and second rods and synchronizes the first and second rods in opposite directions. And a lock receiving portion that is provided on the fixing member and from which the tip ends of the first and second rods enter and exit.

しかし、従来のロック装置にはつぎの問題点がある。
ギアを用いているため、第１、第２のロッドとギアとを正規の位置からずれて組付けてしまう（連結してしまう）おそれがある。第１、第２のロッドとギアとの組付け位置（連結位置）がずれると、左右のロッドの先端部とロック受け部との嵌合ラップ量が左右で異なってしまい、その事がロッドの片掛かりや、ロッドの抜け不良の原因となる。
そのため、ギアと第１、第２のロッドの単品精度を満足しなければならないだけでなく、ロッドとギアとを組付けるときには、その工程で十分に組付け位置管理をしなければならず、日常の工程管理が非常に大変である。
特開２００５−１０４１９２号公報 However, the conventional locking device has the following problems.
Since the gear is used, there is a possibility that the first and second rods and the gear are assembled (coupled) by shifting from the normal position. If the assembly position (connection position) of the first and second rods and the gear is shifted, the amount of fitting wrap between the left and right rod tip portions and the lock receiving portion will be different on the left and right sides. This may cause one-side hooks or defective rod removal.
Therefore, not only must the accuracy of the single gear and the first and second rods be satisfied, but when the rod and gear are assembled, the assembly position must be sufficiently managed in the process. The process management is very difficult.

上記（１）のロック装置によれば、リンクが、回動軸部と第１、第２のアーム部を備えており、第１のアーム部で第１のロッドと連結され第２のアーム部で第２のロッドと連結されているため、リンクが回動軸部まわりに回動したとき、第１、第２のアーム部が互いに反対方向に動き、第１、第２のロッドを互いに反対方向に同期させて動かすことができる。すなわち、リンクを用いているため、第１、第２のロッドとリンクとの組付け時にずれて組付けてしまう事は起こり得ず、第１、第２のロッドとリンクの単品精度が満足されれば、第１、第２のロッドの先端位置はロック受け部に対して正規の位置を確保できる。そのため、第１、第２のロッドのロック受け部との嵌合ラップ量が左右で異なることを従来に比べて抑制でき、第１、第２のロッドの片掛かりや抜け不良が発生することを従来に比べて抑制できる。
また、第１のロッド側突起部をリンクの第１の孔に嵌め込み、第２のロッド側突起部をリンクの第２の孔に嵌め込むだけで、第１、第２のロッドとリンクを連結できる。
また、第１、第２の孔が丸孔形状であるため、第１、第２の孔が長孔形状である場合に比べて、第１、第２のロッド側突起部と第１、第２の孔との嵌合部にスキが発生することを抑制できる。そのため、第１、第２のロッドを確実に反対方向に同量移動させることができ、第１、第２のロッドの片掛かりや抜け不良防止に有効である。 According to the locking device of (1) above, the link includes the rotation shaft portion and the first and second arm portions, and the second arm portion is connected to the first rod at the first arm portion. Since the first and second arm portions move in opposite directions when the link is rotated around the rotation shaft portion, the first and second rods are opposite to each other. It can be moved in sync with the direction. In other words, since the link is used, it is not possible that the first and second rods and the link are assembled in a shifted state, and the single product accuracy of the first and second rods and the link is satisfied. If it does, the front-end | tip position of a 1st, 2nd rod can ensure a regular position with respect to a lock | rock receiving part. Therefore, it can suppress that the amount of fitting laps with the lock receiving part of the 1st and 2nd rods differs in right and left compared with the past, and it can occur that the 1st and 2nd rods are caught on one side and are defective. It can be suppressed compared to the conventional case.
Also, the first and second rods can be connected to the link simply by fitting the first rod-side protrusion into the first hole of the link and the second rod-side protrusion into the second hole of the link. it can.
In addition, since the first and second holes are round holes, the first and second rod side protrusions and the first and second holes are compared to the case where the first and second holes are long holes. It is possible to suppress the occurrence of a gap in the fitting portion with the second hole. Therefore, the first and second rods can be reliably moved in the opposite directions by the same amount, which is effective for preventing the first and second rods from being caught on one side and coming off .

In the embodiment of the present invention, the link 40 includes a rotating shaft portion 41 and first and second arm portions 42 and 43, and is connected to the first rod 30 by the first arm portion 42 and the second arm portion 42. Since the arm portion 43 is connected to the second rod 30, when the link 40 rotates around the rotation shaft portion 41, the first and second arm portions 42 and 43 move in opposite directions, and the first The first and second rods 20 and 30 can be moved in synchronization with each other in opposite directions. In other words, since the link 40 is used, the first and second rods 20 and 30 cannot be displaced and assembled when the link 40 is assembled, and the first and second rods 20 and 30 are not assembled. As a result, it is very easy to manage the position of the link 40 and the link 40. Therefore, if the single product accuracy of the first and second rods 20 and 30 and the link 40 is satisfied, the tip positions of the first and second rods 20 and 30 are secured to the lock receiving portion 50. it can. Therefore, it can suppress compared with the past that the amount of fitting laps with the lock receiving part 50 of the 1st, 2nd rods 20 and 30 differs in the right and left, and the 1st and 2nd rods 20 and 30 Occurrence of missing defects can be suppressed as compared to the conventional case.

従来のロック装置では、ギアを用いているため、ギアの保持およびギアと第１、第２のロッドとの外れ防止のためにギアホルダを要するが、本発明実施例では、リンク４０を用いているため、リンク４０を可動部材２に回動軸部４１で取付けるとともに第１、第２のロッド２０，３０に抜け防止用爪２３，３３を設けることで、リンク４０の保持およびリンク４０と第１、第２のロッド２０，３０との外れ防止のためのリンクホルダは不要である。そのため、従来に比べてロック装置１０の構成品数を削減でき、低コスト化をはかれる。   Since the conventional locking device uses a gear, a gear holder is required for holding the gear and preventing the gear and the first and second rods from coming off. In the embodiment of the present invention, the link 40 is used. For this reason, the link 40 is attached to the movable member 2 by the rotation shaft portion 41, and the first and second rods 20 and 30 are provided with the prevention claws 23 and 33 so that the link 40 is held and the link 40 and the first A link holder for preventing disengagement from the second rods 20 and 30 is not necessary. Therefore, the number of components of the lock device 10 can be reduced compared to the conventional case, and the cost can be reduced.

第１のロッド側突起部２２がリンク４０の第１の孔４２ａに嵌め込まれ、第２のロッド側突起部３２がリンク４０の第２の孔４３ａに嵌め込まれるため、第１のロッド側突起部２２をリンク４０の第１の孔４２ａに嵌め込み、第２のロッド側突起部３２をリンク４０の第２の孔４３ａに嵌め込むだけで、第１、第２のロッド２０，３０とリンク４０を連結できる。   Since the first rod side protrusion 22 is fitted into the first hole 42a of the link 40 and the second rod side protrusion 32 is fitted into the second hole 43a of the link 40, the first rod side protrusion 22 is fitted into the first hole 42a of the link 40, and the second rod side protrusion 32 is fitted into the second hole 43a of the link 40, so that the first and second rods 20, 30 and the link 40 are connected. Can be linked.

つぎに、本発明各実施例に特有な部分を説明する。
〔実施例１〕（図１〜図６）
本発明実施例１では、図５に示すように、リンク４０の第１、第２の孔４２ａ、４３ａが丸孔形状である場合を示している。
リンク４０は、図６に示すように、操作部６０を操作していないとき（初期位置にあるとき）、第１、第２のロッド２０，３０の延び方向と直交する方向（たとえば鉛直方向）に延びる面Ｓから一側にα°傾いた位置にあり、操作部６０を最大限に操作したとき（最大使用位置にあるとき）、面Ｓから他側にα°傾いた位置にある。すなわち、リンク４０は、リンク４０の回動範囲の中央で面Ｓを跨ぐことになる。
第１、第２の孔４２ａ、４３ａの周縁の一部には、図５に示すように、第１、第２のロッド側突起部２２，３２の抜け防止用爪２３，３３挿通用の溝４２ｂ、４３ｂが設けられている。 Next, parts unique to each embodiment of the present invention will be described.
[Example 1] (FIGS. 1 to 6)
In the first embodiment of the present invention, as shown in FIG. 5, the first and second holes 42 a and 43 a of the link 40 have a round hole shape.
As shown in FIG. 6, the link 40 is in a direction (for example, a vertical direction) orthogonal to the extending direction of the first and second rods 20 and 30 when the operation unit 60 is not operated (when it is in the initial position). When the operation unit 60 is operated to the maximum (when it is in the maximum use position), it is at a position inclined α ° from the surface S to the other side. That is, the link 40 straddles the surface S at the center of the rotation range of the link 40.
As shown in FIG. 5, grooves for inserting the first and second rod-side protrusions 22 and 32 into the removal preventing claws 23 and 33 are formed in part of the peripheral edges of the first and second holes 42a and 43a. 42b and 43b are provided.

本発明実施例１では、第１、第２の孔４２ａ、４３ａが丸孔形状であるため、第１、第２の孔４２ａ、４３ａが長孔形状である場合に比べて、第１、第２のロッド側突起部２２，３２と第１、第２の孔４２ａ、４３ａとの嵌合部にスキが発生することを抑制できる。そのため、第１、第２のロッド２０，３０を確実に反対方向に同量移動させることができ、第１、第２のロッド２０，３０の片掛かりや抜け不良防止に有効である。
また、リンク４０が、リンク４０の回動範囲の中央で面Ｓを跨ぐため、リンク４０が回動することによって第１、第２のロッド側突起部２２，３２がロッド延び方向と直交する方向（図６の上下方向）に移動するが、その移動範囲を最小限に抑えることができる。 In the first embodiment of the present invention, since the first and second holes 42a and 43a are round holes, the first and second holes 42a and 43a are first and second compared to the case where the first and second holes 42a and 43a are long holes. It is possible to suppress the occurrence of a gap in the fitting portion between the two rod-side protrusions 22 and 32 and the first and second holes 42a and 43a. Therefore, the first and second rods 20 and 30 can be reliably moved in the opposite direction by the same amount, which is effective for preventing the first and second rods 20 and 30 from being caught on one side and coming off.
Further, since the link 40 straddles the surface S in the center of the rotation range of the link 40, the first and second rod-side protrusions 22 and 32 are orthogonal to the rod extending direction when the link 40 rotates. Although moving in the vertical direction in FIG. 6, the moving range can be minimized.

〔実施例２〕（図７〜図９）
本発明実施例２では、図９に示すように、リンク４０の第１、第２の孔４２ａ、４３ａが長孔形状である場合を示している。第１、第２の孔４２ａ、４３ａの長手方向は、回動軸部４１から直線状に離れる方向である。
リンク４０は、操作部６０を操作していないとき（初期位置にあるとき）、第１、第２のロッド２０，３０の延び方向と直交する方向（たとえば鉛直方向）に延びる面Ｓから一側にα°傾いた位置にあり、操作部６０を最大限に操作したとき（最大使用位置にあるとき）、面Ｓから他側にα°傾いた位置にあるように設定されている。すなわち、リンク４０は、リンク４０の回動範囲の中央で面Ｓを跨ぐことになるように設定されている。 [Example 2] (FIGS. 7 to 9)
In the second embodiment of the present invention, as shown in FIG. 9, the first and second holes 42a and 43a of the link 40 have a long hole shape. The longitudinal directions of the first and second holes 42 a and 43 a are directions away from the rotation shaft portion 41 in a straight line.
When the operation unit 60 is not operated (when in the initial position), the link 40 is on one side from the surface S extending in a direction (for example, the vertical direction) perpendicular to the extending direction of the first and second rods 20 and 30. When the operation unit 60 is operated to the maximum (when it is in the maximum use position), the position is set so as to be inclined α ° from the surface S to the other side. That is, the link 40 is set so as to straddle the surface S at the center of the rotation range of the link 40.

本発明実施例２では、第１、第２の孔４２ａ、４３ａが長孔形状であるため、第１、第２のロッド側突起部２２，３２が第１、第２の孔４２ａ、４３ａ内で第１、第２の孔４２ａ、４３ａの長手方向に拘束を受けることを抑制できる。そのため、第１、第２のロッド側突起部２２，３２は、第１、第２の孔４２ａ、４３ａ内で第１、第２の孔４２ａ、４３ａの長手方向に移動することができる。そのため、リンク４０が回動して第１、第２の孔４２ａ、４３ａの位置がロッド長手方向と直交する方向（図９の上下方向）に移動しても、第１、第２のロッド２０，３０の姿勢が傾くことを抑制できる。その結果、リンク４０が回動しても、第１、第２のロッド２０，３０とロック受け部５０との間に発生する摺動抵抗を抑制できる。   In the second embodiment of the present invention, since the first and second holes 42a and 43a are elongated holes, the first and second rod side protrusions 22 and 32 are in the first and second holes 42a and 43a. Thus, it is possible to suppress the restriction in the longitudinal direction of the first and second holes 42a and 43a. Therefore, the 1st, 2nd rod side projection parts 22 and 32 can move to the longitudinal direction of the 1st and 2nd holes 42a and 43a within the 1st and 2nd holes 42a and 43a. Therefore, even if the link 40 rotates and the positions of the first and second holes 42a and 43a move in the direction perpendicular to the longitudinal direction of the rod (vertical direction in FIG. 9), the first and second rods 20 , 30 can be prevented from tilting. As a result, even if the link 40 rotates, the sliding resistance generated between the first and second rods 20 and 30 and the lock receiving portion 50 can be suppressed.
