Since the frictional force between the roller and the moving body can be adjusted by the force pressed against the moving body, the moving body can be moved with a simple configuration and an appropriate driving force. In addition, even if the surface of the moving body that comes into contact with the roller is uneven or bent and deformed, the displacement of the uneven portion and the displacement of the bending are absorbed by the expansion and contraction of the elastic member, so the roller always moves with appropriate pressure. The body is pressed, and an appropriate frictional force is generated between the moving body and the roller, so that the moving body can be moved.

以下、本発明の実施の形態例を図面に基づいて説明する。実施形態例では、自動引出し装置及び自動扉装置を例に説明するが、本発明に係る移動体駆動装置はこれに限定されるものではなく、移動体全般の移動に使用することが可能である。図１は本発明に係る移動体駆動装置の構成を示す図で、図１（ａ）は平面図、図１（ｂ）は右側面図、図１（ｃ）は正面断面図である。   Embodiments of the present invention will be described below with reference to the drawings. In the embodiment, an automatic drawer device and an automatic door device will be described as an example. However, the moving body driving device according to the present invention is not limited to this, and can be used for moving the entire moving body. . 1A and 1B are diagrams showing a configuration of a moving body driving apparatus according to the present invention, in which FIG. 1A is a plan view, FIG. 1B is a right side view, and FIG. 1C is a front sectional view.

本移動体駆動装置１０は第１の支持部材としての内枠体１１に軸１２ａを中心に回転自在に支持された回転部材としてのローラ１２と、モータ１３を具備する。モータ１３の回転力はモータギヤ１４、中間ギヤ１５を介してローラ１２に伝達されるようになっている。即ち、モータ１３、モータギヤ１４、中間ギヤ１５でローラ１２を回転する駆動手段を構成する。ローラ１２は合成樹脂（ここではウレタン樹脂を用いている）で形成されている。１８、１９、２０は一端が第２の支持部材としての外枠体２４に固定されたガイドピンであり、該ガイドピン１８、１９、２０の他端は内枠体１１の両端及び側部に形成された３個の耳部１１ａ、１１ｂ、１１ｃに形成されたガイドピン貫通穴を貫通している。ガイドピン１８、１９、２０のそれぞれの外周で且つ内枠体１１の耳部１１ａ、１１ｂ、１１ｃ下面と外枠体２４内底面間には弾性部材としてのコイルバネ（圧縮バネ）２１、２２、２３が設けられている。   The moving body driving device 10 includes a roller 12 as a rotating member supported by an inner frame 11 as a first supporting member so as to be rotatable about a shaft 12a, and a motor 13. The rotational force of the motor 13 is transmitted to the roller 12 via the motor gear 14 and the intermediate gear 15. That is, the motor 13, the motor gear 14, and the intermediate gear 15 constitute driving means for rotating the roller 12. The roller 12 is made of synthetic resin (here, urethane resin is used). Reference numerals 18, 19, and 20 are guide pins fixed at one end to an outer frame body 24 as a second support member, and the other ends of the guide pins 18, 19, and 20 are connected to both ends and side portions of the inner frame body 11. It penetrates the guide pin through holes formed in the three formed ear portions 11a, 11b, and 11c. Coil springs (compression springs) 21, 22, 23 as elastic members between the outer periphery of each of the guide pins 18, 19, 20 and between the lower surfaces of the ear portions 11 a, 11 b, 11 c of the inner frame body 11 and the inner bottom surface of the outer frame body 24. Is provided.

ローラ１２の外周の一部は内枠体１１の上面より所定寸法突出しており、図２に示すように、例えば引出しの底板３６に取付けられたライナー押されると、各コイルバネ２１、２２、２３は圧縮され、内枠体１１は外枠体２４内に下降する。即ち内枠体１１は外枠体２４にガイドピン１８、１９、２０、コイルバネ２１、２２、２３を介して直線的に移動自在に支持されている。なお、１７は内枠体１１の耳部１１ａ、１１ｂ、１１ｃがガイドピン１８、１９、２０を飛び出るのを阻止する止め輪である。   A part of the outer periphery of the roller 12 protrudes from the upper surface of the inner frame 11 by a predetermined dimension. As shown in FIG. 2, when the liner attached to the bottom plate 36 of the drawer is pressed, each coil spring 21, 22, 23 is The inner frame body 11 is lowered into the outer frame body 24 by being compressed. That is, the inner frame 11 is supported on the outer frame 24 via the guide pins 18, 19, 20 and the coil springs 21, 22, 23 so as to be linearly movable. Reference numeral 17 denotes a retaining ring that prevents the ear portions 11a, 11b, and 11c of the inner frame body 11 from popping out of the guide pins 18, 19, and 20.

図３及び図４は上記移動体駆動装置を引出し装置に取り付けて自動引出し装置とした構成例を示す図で、図３は引出し装置全体の構成を示す一部切り欠き側面図、図４は移動体駆動装置の取付部を示す図である。図示するように、引出し装置３０は複数段（図では３段）の引出しを有し、最下段の引出し３１を収納する底枠板３３の前端部に本発明に係る移動体駆動装置１０が取り付けられている。   3 and 4 are diagrams showing a configuration example in which the movable body driving device is attached to the drawer device to form an automatic drawer device, FIG. 3 is a partially cutaway side view showing the configuration of the entire drawer device, and FIG. It is a figure which shows the attaching part of a body drive device. As shown in the figure, the drawer device 30 has a plurality of drawers (three stages in the figure), and the movable body drive device 10 according to the present invention is attached to the front end portion of the bottom frame plate 33 that houses the lowermost drawer 31. It has been.

底枠板３３の前端部に移動体駆動装置１０を取付けるための凹部３４が形成され、該凹部３４内に上記構成の移動体駆動装置１０の外枠体２４が挿入され、底枠板３３にビス（図示せず）等で固定されている。この状態で、移動体駆動装置１０のローラ１２が引出し３１の底板３６の下面に貼り付けたランナー３５で押され、移動体駆動装置１０は図２に示す状態となる。この状態で移動体駆動装置１０のモータ１３を駆動すると、上記のようにローラ１２とランナー３５の間に発生する摩擦力により引出し３１は前進し、最終的には図５に示す状態となる。この時、引出し３１の後端部に下面が底板３６の下面と同一面となる突出部３１ａを設け（図４（ａ）参照）、この突出部３１ａの下面にもランナー３５を貼り付けることにより、引出し３１を内容物の取出しが容易にできる位置まで前進させることができる。また、図４（ｂ）に示すように、突出部３１ａと一体となった形状のランナー３５を底板３６に取付けてもよい。本自動引出し装置３０はローラ１２が固定的な接点を持たないため、図６に示すように、取外し可能な引出しに対応できる。   A concave portion 34 for attaching the moving body drive device 10 is formed at the front end portion of the bottom frame plate 33, and the outer frame body 24 of the movable body drive device 10 having the above configuration is inserted into the concave portion 34, and the bottom frame plate 33 is inserted into the bottom frame plate 33. It is fixed with a screw (not shown) or the like. In this state, the roller 12 of the moving body driving device 10 is pushed by the runner 35 attached to the lower surface of the bottom plate 36 of the drawer 31, and the moving body driving device 10 is in the state shown in FIG. When the motor 13 of the moving body driving apparatus 10 is driven in this state, the drawer 31 moves forward by the frictional force generated between the roller 12 and the runner 35 as described above, and finally the state shown in FIG. At this time, a protrusion 31a whose lower surface is flush with the lower surface of the bottom plate 36 is provided at the rear end of the drawer 31 (see FIG. 4A), and the runner 35 is attached to the lower surface of the protrusion 31a. The drawer 31 can be advanced to a position where the contents can be easily taken out. Moreover, as shown in FIG.4 (b), you may attach to the bottom plate 36 the runner 35 of the shape united with the protrusion part 31a. Since the roller 12 does not have a fixed contact, the automatic drawer 30 can cope with a removable drawer as shown in FIG.

本移動体駆動装置ではコイルバネ２１、２２、２３の伸張力により内枠体１１を押し上げローラ１２を引出し３１の底板３６の下面に貼り付けたランナー３５に押し付ける。このことにより、引出し底の高さ誤差をコイルバネ２１、２２、２３の伸縮により吸収し、確実にローラ１２を引出し３１の底面に押し付け、動力伝達のためのローラ１２とランナー３５の摩擦力を発生させる。特に取外し可能な引出しは、固定式の引出しに比べて高さ方向の誤差が出やすいので、本移動体駆動装置１０は好適である。また、引出し３１に重量の大きい物品を収納し、該引出し３１の底板３６に撓みが生じた場合でも、コイルバネ２１、２２、２３の収縮によりこの撓みによる変位を吸収できるからローラ１２とランナー３５の間には適切な摩擦力が生じ、引出し３１の引出し方向及び引込み方向への移動が可能となる。   In this moving body driving apparatus, the inner frame 11 is pushed up by the extension force of the coil springs 21, 22, 23, and the roller 12 is pressed against the runner 35 attached to the lower surface of the bottom plate 36 of the drawer 31. As a result, the height error of the drawer bottom is absorbed by the expansion and contraction of the coil springs 21, 22, and 23, and the roller 12 is reliably pressed against the bottom surface of the drawer 31 to generate the frictional force between the roller 12 and the runner 35 for power transmission. Let In particular, the movable body driving device 10 is suitable for a removable drawer because an error in the height direction is likely to occur compared to a fixed drawer. Further, even when a heavy article is stored in the drawer 31 and the bottom plate 36 of the drawer 31 is bent, the displacement due to the bending can be absorbed by the contraction of the coil springs 21, 22, 23. An appropriate frictional force is generated between them, and the drawer 31 can move in the drawing direction and the drawing direction.

図７は本発明に係る移動体駆動装置の他の構成例を示す斜視図である。本移動体駆動装置４０は、第２の支持部材としての板状の外枠体４１の中央部に開口４２を設け、該開口４２からローラ１２を所定量突出させている。外枠体４１の一側部を所定間隔で切欠き且つ下方に折り曲げて回動支持軸支持部４１ａ、４１ｂを設け、この回動支持軸支持部４１ａ、４１ｂ第１の支持部材としての内枠体４６を回動支持軸４４で回動自在に支持すると共に、該回動支持軸４４の両端部にバネ４５、４５（図では一端部のみのバネ４５を示す）を取付ける。   FIG. 7 is a perspective view showing another configuration example of the moving body driving apparatus according to the present invention. In the moving body drive device 40, an opening 42 is provided at the center of a plate-like outer frame 41 serving as a second support member, and the roller 12 protrudes from the opening 42 by a predetermined amount. One side portion of the outer frame body 41 is cut out at a predetermined interval and bent downward to provide rotation support shaft support portions 41a and 41b. The rotation support shaft support portions 41a and 41b are inner frames as first support members. The body 46 is rotatably supported by a rotation support shaft 44, and springs 45, 45 (the spring 45 of only one end is shown in the figure) are attached to both ends of the rotation support shaft 44.

内枠体４６には図１の内枠体１１と同様、ローラ１２、中間ギヤ１５及びモータギヤ１４が回転自在に支持されている。上記のように内枠体４６は回動支持軸４４により、外枠体４１に回動自在に支持され、バネ４５、４５の弾性力により回動支持軸４４を中心にローラ１２が開口４２から突出する方向に付勢されている。即ち、内枠体４６は回動支持軸４４及びバネ４５、４５を介して外枠体４１に揺動自在に支持され、その自由端がバネ４５、４５の弾性力により開口４２から突出する方向に付勢されている。このような構成の移動体駆動装置４０でも上記と同様、底枠板３３の前端部に形成された凹部３４内に回動支持軸支持部４１ａ、４１ｂ及び内枠体４６を挿入し、底枠板３３に外枠体４１を固定することにより、内枠体４６の自由端が底板３６に近づくようにバネ４５、４５の弾性力で付勢され、自動引出し装置を構成する。   As in the case of the inner frame 11 in FIG. 1, the roller 12, the intermediate gear 15, and the motor gear 14 are rotatably supported on the inner frame 46. As described above, the inner frame body 46 is rotatably supported by the outer frame body 41 by the rotation support shaft 44, and the roller 12 extends from the opening 42 around the rotation support shaft 44 by the elastic force of the springs 45, 45. It is biased in the protruding direction. That is, the inner frame body 46 is swingably supported by the outer frame body 41 via the rotation support shaft 44 and the springs 45, 45, and the free end protrudes from the opening 42 by the elastic force of the springs 45, 45.
