図4は、歯車部材24について説明するための図である。なお、図4(b)には、歯車部材24に加えてバネ部材30を示す。歯車部材24は、筒状部47、周状歯部48、結合孔部50、凸部52およびフランジ部54を有する。
FIG. 4 is a diagram for explaining the gear member 24. FIG. 4B shows a spring member 30 in addition to the gear member 24. The gear member 24 includes a cylindrical portion 47, a circumferential tooth portion 48, a coupling hole portion 50, a convex portion 52, and a flange portion 54.
結合孔部50は、筒状部47の内側に形成され、ベース部材34に軸支される軸孔として機能する。周状歯部48は、筒状部47の外周面に形成され、フランジ部54に支持される。凸部52はフランジ部54の裏面に突出して形成されており、ベース部材34に係止することで歯車部材24の回転止めとして機能する。
The coupling hole portion 50 is formed inside the cylindrical portion 47 and functions as a shaft hole that is pivotally supported by the base member 34. The circumferential tooth portion 48 is formed on the outer peripheral surface of the tubular portion 47 and is supported by the flange portion 54. The convex portion 52 is formed to protrude from the back surface of the flange portion 54, and functions as a rotation stopper for the gear member 24 by being locked to the base member 34.
バネ部材30は、図4(b)に示すように、筒状部47に収容され、歯車部材24を介して第1ロッド26および第2ロッド28を進行方向に付勢する。
As shown in FIG. 4B, the spring member 30 is accommodated in the cylindrical portion 47 and biases the first rod 26 and the second rod 28 in the traveling direction via the gear member 24.
図5は、第1ロッド26について説明するための図である。なお、第1ロッド26および第2ロッド28は同形状であり、第2ロッド28の説明は省略する。第1ロッド26は、先端部56、係合孔部58、段部59および直線状歯部60を有する。
FIG. 5 is a diagram for explaining the first rod 26. In addition, the 1st rod 26 and the 2nd rod 28 are the same shapes, and description of the 2nd rod 28 is abbreviate | omitted. The first rod 26 has a distal end portion 56, an engagement hole portion 58, a step portion 59, and a linear tooth portion 60.
先端部56は、第1ロッド26の進行方向先端側に位置し、グローブボックスのロック部に出入りする。係合孔部58は、操作部材20の伝達部42を挿入可能に形成され、伝達部42に係合する。伝達部42の移動により係合孔部58の内面が押されて、第1ロッド26が退行方向に移動する。伝達部42の動きが第1ロッド26の長手方向(退行方向)に変えられる。
The front end portion 56 is located on the front end side in the traveling direction of the first rod 26 and enters and exits the lock portion of the glove box. The engagement hole 58 is formed so that the transmission part 42 of the operation member 20 can be inserted, and engages with the transmission part 42. The inner surface of the engagement hole 58 is pushed by the movement of the transmission portion 42, and the first rod 26 moves in the backward direction. The movement of the transmission part 42 is changed in the longitudinal direction (retraction direction) of the first rod 26.
直線状歯部60は、第1ロッド26の進行方向後端側に位置し、直線状に配置された歯部である。直線状歯部60は、歯車部材24の周状歯部48に噛合し、歯車部材24の回転運動を直線運動に変換する。段部59は、直線状歯部60より先端部56側に形成され、ベース部材34への挿入時に第1ロッド26がベース部材34に挿入されすぎないように制限する。

FIG. 6 is a perspective view of the base member 34. FIG. 7A is a rear view of the base member 34, and FIG. 7B is a side view of the base member 34. The base member 34 is formed in a box shape, accommodates the gear member 24 and the spring member 30, and supports the first rod 26 and the second rod 28.
ベース部材34は、軸部62と、第1ガイド部64aおよび第2ガイド部64b(これらを区別しない場合「ガイド部64」という)と、係止部66とを有する。軸部62は、ベース部材34の底部61の中央に位置し、底部61から柱状に立設する。軸部62は、歯車部材24の結合孔部50に挿入して歯車部材24を回転可能に軸支する。軸部62の先端は径方向外向きに張り出しており、歯車部材24を抜け止め可能である。
The base member 34 includes a shaft portion 62, a first guide portion 64 a and a second guide portion 64 b (referred to as “guide portion 64” if they are not distinguished from each other), and a locking portion 66. The shaft portion 62 is located in the center of the bottom portion 61 of the base member 34 and is erected in a column shape from the bottom portion 61. The shaft portion 62 is inserted into the coupling hole portion 50 of the gear member 24 and rotatably supports the gear member 24. The tip end of the shaft portion 62 projects outward in the radial direction, and the gear member 24 can be prevented from coming off.
第1ガイド部64aおよび第2ガイド部64bは、ベース部材34の側壁を貫通して、それぞれ一対形成される。ガイド部64は、挿通されたロッド26,28の進退をガイドする。図7(b)に示すように、ガイド部64には段差68が形成されており、ロッド26,28の幅方向の位置ずれを制限して、噛合の解除を抑えている。
A pair of the first guide part 64a and the second guide part 64b are formed through the side wall of the base member 34. The guide part 64 guides the forward and backward movement of the inserted rods 26 and 28. As shown in FIG. 7B, a step 68 is formed in the guide portion 64, and the positional deviation in the width direction of the rods 26 and 28 is limited to suppress the release of meshing.
係止部66は、ベース部材34の底部61または上壁から延出する弾性片であり、図7(a)に示すように側方に張り出す。係止部66の周りには係止部66が回転するためのスリット67がベース部材34の底部61に形成される。係止部66は、歯車部材24の凸部52に係止する凹部66aを有し、歯車部材24の回転を止める。係止部66は、ベース部材34の側面より外側に張り出し、ユーザが操作可能となっている。
The locking portion 66 is an elastic piece extending from the bottom 61 or the upper wall of the base member 34, and projects to the side as shown in FIG. A slit 67 for rotating the locking portion 66 is formed around the locking portion 66 in the bottom portion 61 of the base member 34. The locking portion 66 has a recess 66 a that locks with the convex portion 52 of the gear member 24, and stops the rotation of the gear member 24. The locking portion 66 projects outward from the side surface of the base member 34 and can be operated by the user.
図3に戻る。歯車部材24およびバネ部材30は、ベース部材34に収容され、第1ロッド26は、第1ガイド部64aに挿通され、第2ロッド28は、第2ガイド部64bに挿通される。このように、ベース部材34によって、歯車部材24、バネ部材30、第1ロッド26および第2ロッド28が一体に組み付けられ、第2のサブアッセンブリが組み立てられる。これにより、部材ごとに開閉部材12まで搬送する場合と比べて、ロック装置10を部分的にユニット化して動作確認をした後、容易に搬送できる。
Return to Fig. 3. The gear member 24 and the spring member 30 are accommodated in the base member 34, the first rod 26 is inserted through the first guide portion 64a, and the second rod 28 is inserted through the second guide portion 64b. In this manner, the gear member 24, the spring member 30, the first rod 26, and the second rod 28 are integrally assembled by the base member 34, and the second subassembly is assembled. Thereby, compared with the case where it conveys to the opening-and-closing member 12 for every member, after locking device 10 is partially unitized and operation check is carried out, it can convey easily.
第1ロッド26および第2ロッド28は、歯車部材24に噛合しており、互いに連動して進退する。歯車部材24とロッド26,28を噛合することで、歯車部材24の代わりに用いたロータにロッドを固定する場合と比べて、ロータの円運動によってロッド26,28が進退方向に交差する方向に位置ずれすることを抑えられ、ロッド26,28が直線状に進退できる。
The first rod 26 and the second rod 28 mesh with the gear member 24, and advance and retreat in conjunction with each other. By engaging the gear member 24 and the rods 26, 28, the rods 26, 28 cross the advancing / retreating direction due to the circular motion of the rotor as compared with the case where the rod is fixed to the rotor used instead of the gear member 24. The displacement is suppressed, and the rods 26 and 28 can advance and retract linearly.
ロッド26,28の進退をガイドするガイド部64を設けることで、ロッド26,28を滑らかに進退させるとともに、ロッド26,28および歯車部材24の噛合が外れることを抑えることができる。ロッド26,28が開閉部材12の開閉時や閉状態で固定部材のロック部等に当たって荷重を受けた際に、ベース部材34のガイド部64がその荷重を受けることで、経時的な変形によるガタつきの発生を抑え、ロッド26,28の進退を安定させることができる。
By providing the guide portion 64 that guides the forward and backward movement of the rods 26 and 28, the rods 26 and 28 can be smoothly advanced and retracted, and the rods 26 and 28 and the gear member 24 can be prevented from being disengaged. When the rods 26, 28 are subjected to a load when the opening / closing member 12 is opened / closed or in a closed state when the rods 26, 28 are subjected to a load, the guide portion 64 of the base member 34 receives the load. The occurrence of sticking can be suppressed, and the advancement and retraction of the rods 26 and 28 can be stabilized.
図8は、ロック装置10の第2のサブアッセンブリ70の背面図である。第2のサブアッセンブリ70では、ベース部材34の係止部66が歯車部材24の凸部52に係止し、歯車部材24の回転が止められている。係止部66は、バネ部材30に抗してロッド26,28の進行を止めるストッパ構造として機能する。このストッパ構造は、バネ部材30が蓄圧した状態で歯車部材24を係止してロッド26,28の進行を規制し、その係止を解除してバネ部材30の付勢によりロッド26,28を進行させる。これにより第2のサブアッセンブリ70を開閉部材12に取り付ける作業を容易にできる。
FIG. 8 is a rear view of the second subassembly 70 of the locking device 10. In the second subassembly 70, the locking portion 66 of the base member 34 is locked to the convex portion 52 of the gear member 24, and the rotation of the gear member 24 is stopped. The locking portion 66 functions as a stopper structure that stops the movement of the rods 26 and 28 against the spring member 30. This stopper structure locks the gear member 24 with the spring member 30 accumulating to restrict the progression of the rods 26, 28, releases the lock, and biases the spring members 30 to cause the rods 26, 28 to move. Make it progress. Thereby, the operation | work which attaches the 2nd subassembly 70 to the opening-and-closing member 12 can be made easy.
歯車部材24は、係止部66に係止された状態で、バネ部材30によりロッド26,28の進行方向に付勢されており、係止部66の係止が解除されると、回転してロッド26,28を進行方向に移動させる。
The gear member 24 is urged in the advancing direction of the rods 26 and 28 by the spring member 30 in a state of being locked to the locking portion 66, and rotates when the locking of the locking portion 66 is released. Then, the rods 26 and 28 are moved in the traveling direction.
