  However, since the slide rail structure according to the conventional example is a rail 1 having a substantially C-shaped cross section that opens to the side, dust, dust, and the like easily enter the inside of the rail 1 from the side opening 3. In addition, dust, dust and the like that have entered from the shape cannot be easily removed. When dust or dust accumulates, the slidability of the runner 2 that slides along the rail 1 decreases, and the runner 2 cannot slide smoothly. .

  The present invention has been made in view of the above-mentioned background art, and the problem is that the entry of dust, dirt, etc. into the rail is prevented, and the runner can slide smoothly along the rail for a long period of time. It is providing the slide rail structure which becomes.

  In order to solve the above-described problems, a slide rail structure of the present invention includes a rail having a substantially C-shaped cross section that opens to the side, and a runner that slidably travels within the rail. This is a slide rail structure provided with a member support portion that protrudes outward from the side opening, and a large number of thin flat plate-like shielding pieces that close the side opening of the rail are arranged along the longitudinal direction, and each shielding is provided. The piece is pivotally supported by the upper edge portion of the side opening so as to be swingable in the longitudinal direction, and rotates upward when the member support portion of the runner moving along the side opening contacts. Then, after passing through the member support portion, it is rotated downward by its own weight and restored to a state of closing the side opening.

  In the slide rail structure of the present invention, since a large number of thin flat plate-like shielding pieces that close the side openings of the rail are arranged along the longitudinal direction, entry of dust, dust, etc. into the rail is shielded. It is prevented by the piece, and it becomes difficult for dust and dirt to accumulate in the rail.

  Each shielding piece is pivotally supported by the upper edge portion of the side opening so as to be swingable in the longitudinal direction, and the runner member supporting portion moving along the side opening is in contact with the upper side. Since the runner rotates and retracts, the runners can smoothly slide along the rails without the hindrance of each shielding piece. In addition, each shielding piece is rotated downward by its own weight after passing through the member supporting portion and restored to a state in which the side opening is closed, so that intrusion of dust or dirt into the rail is reliably prevented, Accumulation of dust and dirt in the rail is also reliably prevented, and the smooth running performance of the runner is maintained for a long time.

  1 and 2 show an embodiment corresponding to all claims 1 to 3 of the present application. The slide rail structure of this embodiment includes a rail 1 having a substantially C-shaped cross section that opens to the side, and a runner 2 that slidably travels within the rail 1. A member support portion 4 that protrudes outward from the side opening 3 is provided.

  In this case, a large number of thin flat plate-like shielding pieces 5 a and 5 b that close the side opening 3 of the rail 1 are arranged along the longitudinal direction, and each shielding piece 5 a and 5 b is formed on the side opening 3. The upper edge portion is pivotally supported so as to be swingable in the longitudinal direction, and the member support portion 4 of the runner 2 that moves along the side opening 3 is brought into contact with the upper edge portion so that it is pivoted upward X and retracted. After passing through the member support portion 4, it is rotated Y downward by its own weight and restored to a state of closing the side opening 3.

  Further, in the slide rail structure of this embodiment, both side edges 51 of the shielding pieces 5a and 5b to which the member support portion 4 of the runner 2 is slidably contacted are formed in a tapered shape, and the shielding pieces 5a and 5b are formed with a lower width. Narrow shape. In addition, the shielding pieces 5a and 5b are arranged with their positions alternately shifted back and forth so that the side edges 51 of the adjacent shielding pieces 5a and 5b are close to each other.

  Hereinafter, the slide rail structure of this embodiment will be described in more detail. The slide rail structure of this embodiment can be used as a running rail structure that slidably supports curtains, slide doors, etc., or a hanger rail structure in which various interior members such as painting panels and display racks are suspended and held. It is constructed indoors.

  The rail 1 has a substantially C-shaped cross section that opens laterally, and is formed of an aluminum extrusion mold. The rail 1 having a substantially C-shaped cross section includes an upper plate portion 6, a lower plate portion 7, and a back plate portion 8, and the back plate portion 8 is fixed and installed above a wall surface 9 in the room. . In this case, the rail 1 may be installed with the upper plate portion 6 fixed to the ceiling surface of the room, and the fixing means is not particularly limited by screwing, bonding or the like.

  Concave grooves 61 and 71 are formed in the upper edge portion (lower front end of the upper plate portion 6) and the lower edge portion (upper front end of the lower plate portion 7) of the side opening 3 of the rail 1 so as to face each other. Has been. The concave groove 61 and the concave groove 71 are arranged side by side in a pair, and the upper and lower end portions of the front-side shielding piece 5a are accommodated in the front-side concave grooves 61 and 71, respectively. The upper and lower end portions of the rear shielding piece 5b are accommodated in 61 and 71, respectively. The upper end portions of the shielding pieces 5a and 5b are pivotally supported by the shaft pin 52 in the concave groove 61, whereby the shielding pieces 5a and 5b can swing freely in the longitudinal direction of the rail 1. The lower end portions of 5a and 5b can be freely moved in and out of the groove 71.

  Each of the shielding pieces 5a and 5b has the same shape, and both side edge portions 51 are formed in a taper shape so as to have a substantially egg shape with a narrower bottom when viewed from the front. Each of the shielding pieces 5a and 5b has a thin plate shape and is formed of metal or synthetic resin, and the shielding pieces 5a and the shielding pieces 5b are disposed so as to be alternately shifted in the front-rear direction. And the side edge parts 51 of the adjacent shielding piece 5a and the shielding piece 5b are mutually close, and the one part has overlapped back and forth.

  The runner 2 has a rolling wheel 10, and when the rolling wheel 10 rolls on the lower plate portion 7 of the rail 1, the runner 2 slides in the rail 1. A shaft core rod 11 serving as a rotation center of the rolling wheel 10 protrudes outward from the side opening 3 of the rail 1 as a member support portion 4, and is formed at the lower end of a support piece 12 provided at the front end of the shaft core rod 11. A hook piece 13 is integrally formed, and a suspended object such as a curtain or various interior members can be detachably locked and held on the hook piece 13.

  When the runner 2 slides along the rail 1, as shown in FIG. 1A, when the runner 2 travels from right to left as viewed in the drawing, the shielding piece 5 a (shielding piece 5b is the same), and the member support portion 4 of the runner 2 is slidably contacted with the side edge portion 51 so as to rotate X and retract (shown by a solid line). It is rotated Y downward by its own weight and automatically restored to a state of closing the side opening 3 (indicated by a two-dot chain line). Even if the runner 2 travels in the opposite direction, the shielding pieces 5a and 5b are similarly swung.

  Therefore, in the slide rail structure of this embodiment, a large number of thin flat plate-like shielding pieces 5a and 5b that close the side opening 3 of the rail 1 are arranged along the longitudinal direction. Intrusion of dust and dirt is prevented by the shielding pieces 5a and 5b, so that dust and dust are less likely to accumulate in the rail 1. Therefore, troublesome cleaning work in the rail 1 for maintaining the slide traveling performance of the runner 2 is reduced.

  Each of the shielding pieces 5a and 5b is pivotally supported by the upper edge portion of the side opening 3 so as to be swingable in the longitudinal direction, and moves along the side opening 3. Since the four come into contact with each other and rotate X, the runner 2 can smoothly slide along the rail 1 without the obstacles of the shielding pieces 5a and 5b.

  In addition, each of the shielding pieces 5a, 5b is rotated Y downward by its own weight after passing through the member support portion 4 and restored to the state of closing the side opening 3, so that the side opening 3 is always closed. As a result, the entry of dust and dirt into the rail 1 is surely prevented, and the accumulation of dirt and dust in the rail 1 is also reliably prevented, so that the runner 2 can slide smoothly. Running performance is maintained for a long time.

  Further, in the slide rail structure of this embodiment, the side edges 51 of the shielding pieces 5a and 5b to which the member support portion 4 of the runner 2 is slidably contacted are formed in a tapered shape, and the shielding pieces 5a and 5b are lowered. Since the shape is narrowed, when the member support 4 of the runner 2 is in sliding contact with the side edges 51 of the shielding pieces 5a and 5b, the shielding pieces 5a and 5b rotate smoothly with little resistance. The retraction / restoration operation of each shielding piece 5a, 5b becomes smooth, and the sliding traveling property of the runner 2 is also improved.

  Furthermore, in the slide rail structure of this embodiment, the shielding pieces 5a and 5b are disposed alternately shifted in the front-rear direction so that the side edges 51 of the adjacent shielding pieces 5a and 5b are close to each other. The gap between the shielding pieces 5a and 5b is reduced, so that intrusion of dust and dirt into the rail 1 is more reliably prevented, and accumulation of dust and dirt in the rail 1 is more reliably prevented. The In this case, since the positions of the shielding pieces 5a and 5b are alternately shifted in the front-rear direction, contact with each other is avoided when the shielding pieces 5a and 5b are rotated.
