Description

本発明は、アウターメンバーに対しインナーメンバーが何度も摺動を繰り返したときに、ボールリテーナが正規の摺動位置から位置ずれを起こすのを防止した、特に複写機の画像走査のため原稿台を移動させるスライドレールに関するものである。 The present invention prevents the ball retainer from being displaced from the normal sliding position when the inner member repeatedly slides with respect to the outer member. It is related with the slide rail which moves.

従来の上記スライドレールは、少なくとも断面略C字形のアウターメンバーと、該アウターメンバーと摺動自在とした断面略C字形のインナーメンバーと、上記両メンバーの屈折縁間で、ボールを回転自在に保持するボールリテーナからなるスライドレールにおいて、上記ボールリテーナに前後方向に渡ってエンドレスバンドがとりつけられ、該エンドレスバンドの内面がボールリテーナの基板の摺動方向端部に回転自在に取り付けられた回転ローラの外面に密着し、インナーメンバーとアウターメンバーに形成された係止孔に取り付けられる係合雌型と、係合雌型に取り付けられる係合雄型よりなる係合部材をもって、エンドレスバンドの一部がインナーメンバー、アウターメンバーと連結されているものである。（特許文献１参照） The conventional slide rail holds the ball rotatably between at least the outer member having a substantially C-shaped cross section, the inner member having a substantially C-shaped cross section that is slidable with the outer member, and the refractive edges of the two members. In a slide rail comprising a ball retainer, an endless band is attached to the ball retainer in the front-rear direction, and an inner surface of the endless band is rotatably attached to an end of the ball retainer in the sliding direction. A part of the endless band has an engaging member composed of an engaging female die attached to an engaging hole formed in the inner member and the outer member, and an engaging male die attached to the engaging female die. It is connected to the inner member and outer member. (See Patent Document 1)

すなわち、上記スライドレールは、回転ローラ、係合雌型、係合雄型等、エンドレスバンドを配設するための部品点数が多くなり、高価なものとなっていた。
特に回転ローラはコストアップにつながる一番の要因でもあった。したがって、回転ローラにかわって、合成樹脂製のベルトガイドをボールリテーナの摺動方向の両端部に取り付けるのが一般的になっている。
一方、上記スライドレールは次のようにして組み立てられる。
まず、エンドレスバンドが装着されたボールリテーナの端部がアウターメンバーのストッパーに当接した状態を維持し、インナーメンバーをボールとスリップさせながら、ボールリテーナの所定位置までボールとスリップさせながら移動させる。次に、インナーメンバーの係止孔よりエンドレスバンドの一部を円弧状に上方に突出せしめて接着材を塗布した係合雌型をエンドレスバンドの下側で係止孔に固着する。
次に、エンドレスバンドを係合雌型の挿通路に位置せしめ、さらに接着剤を塗布した係合雄型を係合雌型の係合凹孔内に、エンドレスバンドと共に嵌合し、固着する。さらに、アウターメンバーの係止孔に上記作業と同様の作業にてエンドレスバンドの一部をアウターメンバーと連結する。 That is, the slide rail has a high number of parts for disposing the endless band, such as a rotating roller, an engaging female mold, and an engaging male mold, and is expensive.
In particular, the rotating roller was the main factor leading to cost increase. Therefore, it is common to attach synthetic resin belt guides to both ends of the ball retainer in the sliding direction instead of the rotating roller.
On the other hand, the slide rail is assembled as follows.
First, while maintaining the state in which the end of the ball retainer to which the endless band is attached is in contact with the stopper of the outer member, the inner member is moved to a predetermined position of the ball retainer while slipping with the ball while slipping with the ball. Next, a part of the endless band protrudes upward in a circular arc shape from the locking hole of the inner member, and the engaging female die coated with an adhesive is fixed to the locking hole below the endless band.
Next, the endless band is positioned in the engaging female mold insertion passage, and the engaging male mold coated with an adhesive is fitted and fixed together with the endless band in the engaging female engaging recess hole. Further, a part of the endless band is connected to the outer member in the same manner as the above operation in the locking hole of the outer member.

このため、インナーメンバーをボールとスリップさせながら、ボールリテーナの所定位置まで移動させる作業（ベルトを両メンバーに固定する前に、アウターメンバー、インナーメンバー、ボールリテーナの位置を正しく配置する作業）、小さな係合雌型、係合雄型に接着剤を塗布する作業、さらに、小さな係合雌型に係合雄型を接着材が塗布された状態で、両メンバーあるいは互いに係合させる作業等、組立て作業が煩雑で、非常に作業効率が悪かった。
又、スライドレールに配設されたエンドレスバンドの長さは、湿度、温度によって変化するので、エンドレスバンドが長くなったとき、張設状態が緩み、ボールリテーナとインナーメンバー間にスリップ現象が発生したり、エンドレスバンドが縮んだ時、張設状態が緊張し、インナーメンバーの動きが重くなることがあった。 For this reason, the work of moving the inner member to a predetermined position of the ball retainer while slipping with the ball (work for correctly arranging the positions of the outer member, the inner member and the ball retainer before fixing the belt to both members), small Assembling the engaging female mold and the engaging male mold by applying an adhesive, and engaging the engaging male mold with a small engaging female mold with the adhesive applied to both members or each other. The work was complicated and the work efficiency was very poor.
Also, the length of the endless band arranged on the slide rail changes depending on humidity and temperature, so when the endless band becomes longer, the tension is loosened and slip phenomenon occurs between the ball retainer and the inner member. Or when the endless band contracts, the tension is tensioned and the movement of the inner member may become heavy.

Is mounted on the ball retainer 3 at the center of the ball retainer 3 in the sliding direction, at a location located opposite to the upper and lower surfaces of the substrate 31, The first fitting locking hole 8 is provided at the center of the sliding direction of the outer member 1 and the inner member 2.), the ball retainer 3 over which the outer member 1, the endless band 4 is stretched, the inner member Bar 2 is assembled as follows.

アウターメンバー１の一方のストッパー１４が形成されていない側から、第１位置決め部材８０と第２位置決め部材８０が摺動方向の中央部位置した状態にエンドレスバンド４が架け渡されたボールリテーナ３を挿入して、ストッパー１４が形成されていない側の端部に位置させる。
そして、インナーメンバー２をストッパー１４が形成されていない側から、アウターメンバー１に挿入し、第１嵌合係止孔８に第１位置決め部材８０が臨む位置まで、インナーメンバー２を摺動する。（このとき、実施例では、インナーメンバー２は、ボールリテーナ３と共に摺動し、アウターメンバー１、ボールリテーナ３の摺動方向のそれぞれの中央部に位置することとなる。） From the side of the outer member 1 where one stopper 14 is not formed, the ball retainer 3 on which the endless band 4 is bridged in a state where the first positioning member 80 and the second positioning member 80 are located in the center of the sliding direction. It is inserted and positioned at the end on the side where the stopper 14 is not formed.
Then, the inner member 2 is inserted into the outer member 1 from the side where the stopper 14 is not formed, and the inner member 2 is slid to a position where the first positioning member 80 faces the first fitting locking hole 8. (At this time, in the embodiment, the inner member 2 slides with the ball retainer 3 and is located at the center of each of the outer member 1 and the ball retainer 3 in the sliding direction.)

次に、第１位置決め部材８０を第１嵌合係止孔８から上方に持ち上げ（図９に示す状態）、第１嵌合部材５を斜め上方から、第１位置決め部材８０の下方に潜らせ、第１位置決め部材８０を保持孔５４に嵌合保持した状態で、第１嵌合部材５を第１嵌合係止孔８の上方から、前後左右載置用突部５１・・・が前記第１嵌合係止孔８の第１載置部８２・・・に当接するまで押し下げると、係止突条５５、５５が第１前後係止部８３、８３の下面に係止し、第１嵌合部材５は、第１位置決め部材８０を保持孔５４に保持した状態で第１嵌合係止孔８に嵌合係止される。 Next, the first positioning member 80 is lifted upward from the first fitting locking hole 8 (the state shown in FIG. 9), and the first fitting member 5 is hidden under the first positioning member 80 from obliquely above. In the state where the first positioning member 80 is fitted and held in the holding hole 54, the front and rear, left and right mounting protrusions 51 are arranged on the first fitting member 5 from above the first fitting locking hole 8. When it is pushed down until it comes into contact with the first mounting portion 82 of the first fitting locking hole 8, the locking protrusions 55, 55 are locked to the lower surfaces of the first front and rear locking portions 83, 83, The first fitting member 5 is fitted and locked in the first fitting locking hole 8 in a state where the first positioning member 80 is held in the holding hole 54.

この時、実施例では、アウターメンバー１の第２嵌合係止孔７に第２位置決め部材７０が臨む状態に自動的に位置するので、上記と同様にして、第２嵌合部材５を第２位置決め部材７０に保持した状態で、第２嵌合係止孔７に嵌合係止し、最後にストッパー１４を立ち上げる。
すなわち、第１、第２位置決め部材８０、７０を所定位置に設けたエンドレスバンド４を、ボールリテーナ３がアウターメンバー１に組み込まれる前に、ボールリテーナ３に架け渡しておく事で、第１嵌合係止孔８、第２嵌合係止孔７と第１、第２位置決め部材８０、７０は自動的に所定箇所で重なり合い、一方側を連結した状態（例えば、インナーメンバー２とエンドレスバンド４を連結した状態）で、他方側（例えばアウターメンバー１)と連結するため、インナーメンバー２、ボールリテーナ３（ボール３０・・・）を強制的にスリップさせる必要がないので作業効率が非常に良い。 At this time, in the embodiment, since the second positioning member 70 is automatically positioned so as to face the second fitting locking hole 7 of the outer member 1, the second fitting member 5 is moved in the same manner as described above. 2 In the state of being held by the positioning member 70, it is fitted and locked in the second fitting and locking hole 7, and finally the stopper 14 is raised.
That is, the endless band 4 provided with the first and second positioning members 80 and 70 at predetermined positions is spanned over the ball retainer 3 before the ball retainer 3 is assembled into the outer member 1. The mating locking hole 8 and the second fitting locking hole 7 and the first and second positioning members 80 and 70 automatically overlap each other at a predetermined position and are connected at one side (for example, the inner member 2 and the endless band 4 In this state, the inner member 2 and the ball retainer 3 (ball 30...) Need not be forced to slip because they are connected to the other side (for example, the outer member 1). .

一方、第１位置決め部材８０を第１嵌合係止孔８から上方に持ち上げた時（図９に示す状態）、あるいは、第２位置決め部材７０を第２嵌合係止孔７から上方に持ち上げた時、ボールリテーナ３の摺動方向の両端部に設けたベルトガイド部材６、６の弾性付与部６６、６６が一旦縮まった状態（図１０（ロ）に示す状態）となり、第１嵌合係止孔８（第２嵌合係止孔７）に第１嵌合部材５（第２嵌合部材５）が嵌合係止した時、正規の状態（図１０（イ）に示す状態）となり、エンドレスバンド４を所定の緊張状態で張設する。
そして、環境の変化(湿度、温度の変化)による、エンドレスバンド４の伸び縮みに対応して、弾性付与部６６が弾性変形し、エンドレスバンド４の安定した張設状態を得る事が出来る。 On the other hand, when the first positioning member 80 is lifted upward from the first fitting locking hole 8 (the state shown in FIG. 9), or the second positioning member 70 is lifted upward from the second fitting locking hole 7. Then, the elasticity applying portions 66 and 66 of the belt guide members 6 and 6 provided at both ends in the sliding direction of the ball retainer 3 are once contracted (the state shown in FIG. 10B), and the first fitting When the first fitting member 5 (second fitting member 5) is fitted and locked in the locking hole 8 (second fitting locking hole 7), the normal state (the state shown in FIG. 10A). Thus, the endless band 4 is stretched in a predetermined tension state.
Then, in response to the expansion and contraction of the endless band 4 due to changes in the environment (changes in humidity and temperature), the elasticity applying portion 66 is elastically deformed, and a stable stretched state of the endless band 4 can be obtained.
