Description

スライドレールSlide rail
　本発明は、電子機器、光学機器、ビジネス機器、家具等々に使用されるスライドレールに関し、特に、アウターメンバとインナーメンバとの間に挿入されたボールの走行面がリン青銅、鉄またはステンレスによって形成されたスライドレールに関する。 The present invention relates to a slide rail used for electronic equipment, optical equipment, business equipment, furniture, and the like, and in particular, a running surface of a ball inserted between an outer member and an inner member is formed of phosphor bronze, iron, or stainless steel. Related slide rails.
　スライドレールは、精度が高く、かつ抵抗が少くなるように設計しているので、精度の要求される精密機械、電子機器、コピー機などの可動部分に広く使用されている。また、大きい重量が加わる場所、たとえば、出入り口の扉や、家庭で使用する多段の抽斗などの家具類等にも広く使用されている。 】 Slide rails are designed to have high accuracy and low resistance, so they are widely used in movable parts such as precision machines, electronic devices, and copiers that require high accuracy. It is also widely used in places where heavy weight is applied, for example, doors at entrances and entrances and furniture such as multistage drawers used at home.
　従来のスライドレールは、アウターメンバである固定レールと、インナーメンバである移動レールの間に、多数のボールをボールリテーナを介して装着した構成である。
　フレームや壁面に装着される固定レールとなるアウターメンバは、両端腕を抱え込んだ形状であり、湾曲した長手方向の内側に半円形溝からなるボール走行面が形成されている。また、移動体に装着される移動レールとなるインナーメンバは、両端腕を外側に向けて湾曲させた形状で、固定レール（アウターメンバ）の内側に嵌入され、湾曲した長手方向の外側に半円形溝からなるボール走行面を備えている。向かい合う固定レールのボール走行面と移動レールのボール走行面が一対となりボール走行路を形成し、そのボール走行路にボールリテーナに保持されたボールが転動自在に介装される。 A conventional slide rail has a configuration in which a large number of balls are mounted via a ball retainer between a fixed rail as an outer member and a moving rail as an inner member.
The outer member, which is a fixed rail attached to the frame and the wall surface, has a shape in which both arms are held, and a ball traveling surface made of a semicircular groove is formed inside the curved longitudinal direction. In addition, the inner member, which is a moving rail attached to the moving body, has a shape in which both end arms are curved outward and is fitted inside the fixed rail (outer member) and is semicircular on the curved outer side in the longitudinal direction. It has a ball running surface consisting of grooves. The ball traveling surface of the fixed rail and the ball traveling surface of the moving rail which face each other form a pair to form a ball traveling path, and a ball held by the ball retainer is rotatably interposed in the ball traveling path.
　固定レール（アウターメンバ）はキャビネットや扉のフレームなどに固定され、移動レール（インナーメンバ）は抽斗や可動部の側面に固定される。抽斗を移動すると移動レールは、ボールが転がることによって、嵌装されている固定レールの長手方向に沿って比較的軽くかつ自在にスライドできる。
　ボール走行路はいずれもボール同程度の曲率の円弧状の断面形状を有しており、内部に摺動自在に装着された移動レールは固定レールから簡単には外れない構造に形成されている。 The fixed rail (outer member) is fixed to a cabinet, a door frame, or the like, and the moving rail (inner member) is fixed to the drawer or the side of the movable part. When the drawer is moved, the moving rail can be slid relatively lightly and freely along the longitudinal direction of the fixed rail that is fitted by rolling the ball.
Each of the ball traveling paths has an arc-shaped cross-sectional shape with a curvature similar to that of the ball, and the moving rail that is slidably mounted therein is formed so as not to be easily detached from the fixed rail.
　しかし、ドアを垂直に吊るして左右に往復スライドさせて使用する場合、スライドレールは垂直方向に並んで配置されるので、スライドレールに加わる抽斗などの荷重は、２対の上下のボールガイド溝に均等に加わることはなく、主に下に位置するボールガイド溝に荷重が掛かる結果となっていた。 However, when the door is suspended vertically and slid back and forth to the left and right, the slide rails are arranged side by side in the vertical direction, so that the load such as a drawer applied to the slide rail is applied to the two pairs of upper and lower ball guide grooves. The load was not applied evenly, and the load was mainly applied to the ball guide groove positioned below.
　また、負荷が大きい場合には、片方のボールガイド溝でも耐えられるように、ボールの径を大きくする事が考えられるが、スライドレール全体を大型化しなければならず、コストアップの原因となる。
　また、荷重は移動レールにかかることになるので、スライドレール全体としては偏心荷重となる欠点もあり、偏心量の大きい荷重の場合にはバランスをとる必要があった。 In addition, when the load is large, it is conceivable to increase the diameter of the ball so that it can withstand one of the ball guide grooves. However, the entire slide rail must be enlarged, resulting in an increase in cost.
Further, since the load is applied to the moving rail, there is a disadvantage that the entire slide rail becomes an eccentric load, and it is necessary to balance in the case of a load having a large amount of eccentricity.
　また、スライドレールを取り付ける取り付け箇所には高さが確保できなければならず、この高さを確保できない場合は、吊り用にスライドレールを横向きにして使用することになる。横向きにすると、ボールガイド溝が横方向からボールを支えることになり、大きな荷重では耐久性に欠けるという問題があった。耐荷重を考慮して、梁に固定レール（アウターメンバ）を上向きに敷設し、吊り下げるドア等を移動レール（インナーメンバ）に跨がせるように装着することも考えられるが、構造が複雑で装備全体が大きくなる欠点があった。 Also, it is necessary to secure the height at the mounting location where the slide rail is attached. If this height cannot be secured, the slide rail will be used sideways for suspension. When it is turned sideways, the ball guide groove supports the ball from the side, and there is a problem that durability is not high at a large load. Considering load-bearing capacity, it may be possible to install a fixed rail (outer member) upward on the beam and mount the hanging door over the moving rail (inner member), but the structure is complicated. There was a drawback that the entire equipment became large.
