Description

    The present invention relates to a sliding door device installed in an opening between an upper wall and a lower wall in a storage room, an exhibition case or the like, and in particular, the shape of the sliding door has a shape whose transverse section is curved in an arc shape. About things.

    As shown in Patent Document 1, a conventional display case has a box-like appearance and has an opening formed on the front wall thereof. A sliding door device including a flat sliding door (glass door) and a guide rail that guides the sliding door so as to be movable in the left-right direction is installed in the opening of the display case. However, if the display case is considered as one of the interiors, new demand can be created if a unique shape other than the box shape can be adopted.

  As the shape of the new display case, for example, a fan-shaped cross section or a columnar shape imitating a column can be considered. In such a case, it is necessary to bend the glass door, which is a sliding door, so that the cross section is arcuate. In addition, the guide rail also needs to be curved in an arc shape along the curved surface of the glass door so that the sliding door can move smoothly on the arc-shaped track.

JP-A-4-216788

  However, it is difficult to accurately curve the glass plate and the guide rail to a predetermined curvature, and when the actually manufactured sliding door is fitted to the guide rail, the curvatures of the two may be shifted. Then, there was a problem that the sliding door could not move smoothly.

    Then, this invention aims at providing the sliding door apparatus which can move a sliding door smoothly, using the thing which is excellent in aesthetics as a sliding door, and whose cross section curved in the shape of an arc.

  In order to achieve the above object, a sliding door device according to the present invention includes a sliding door disposed in an opening between an upper wall and a lower wall and having an arcuate cross section, and the upper wall and / or the lower wall. A guide rail that is fixed and guides the sliding door so as to move in the left-right direction while drawing an arc, and the guide rail is elastic to match the curvature of the outer surface or the inner surface of the sliding door. It is characterized by being formed by adjusting the curvature by deformation.

  According to the above configuration, the guide rail is not curved in advance, but is curved in accordance with the degree of curvature of the sliding door that is actually used. Therefore, there is a risk of mismatch in curvature between the sliding door and the guide rail. And the sliding door can be moved smoothly.

  The guide rail is installed on the upper wall and / or the lower wall. However, it is preferable to install guide rails on both the upper wall and the lower wall in terms of suppressing the wobbling of the sliding door.

  The guide rail is provided with a fixing portion that fixes the guide rail to the upper wall or the lower wall. A plurality of fixing portions are formed at intervals in the left-right direction of the guide rail, and the upper portion in a posture in which the width of the guide rail faces in the vertical direction while the guide rail is curved by the fixing portion. Fixed to the wall or the lower wall.

  According to the said structure, it becomes possible to make the curved surface of a guide rail follow the curved surface of a sliding door, and it becomes possible to move a sliding door smoothly. Moreover, since the guide rail is fixed to the upper wall or the lower wall in a state in which the guide rail is elastically deformed and stressed, the guide rail has high rigidity. Therefore, even if a force is applied from the outside, it is difficult to be deformed, the moving track of the sliding door is stabilized, and the sliding door can be moved more smoothly.

  Furthermore, since a plurality of fixing portions are formed at intervals in the left-right direction with respect to the guide rail, when the guide rails are bent, the fixing portions do not overlap each other and the guide rails can be arbitrarily bent. Is possible.

  The fixing portion can be formed of a member different from the guide rail. For example, a fixed part can be obtained by using a metal fitting having an L-shaped cross section or a U-shaped cross-section and attaching it integrally to the guide rail. The guide rail may be bent at one end in the width direction to form a bent portion, and the bent portion may be cut out to form a plurality of fixed portions.

  The guide rail may be fixed to the lower wall, and a plurality of rollers for conveying the sliding door may be attached to the bottom of the guide rail at intervals in the left-right direction. However, it becomes possible to move the sliding door smoothly.

  In addition to installing one sliding door in the opening, a plurality of sliding doors having different curvatures can be arranged in the opening. In this case, the guide rail of each sliding door may be curved and concentrically arranged in accordance with the curvature of the outer surface or inner surface of the sliding door to be guided, and each sliding door may be configured to be movable in the left-right direction while being pulled from each other. .

  The guide rail is installed along at least one of the outer surface and the inner surface of the sliding door. Preferably, the guide rail is installed along the inner surface of the sliding door. Thereby, a sliding door can be moved smoothly. Furthermore, it is also possible to provide guide rails along the outer and inner surfaces of the sliding door, that is, on both surfaces of the sliding door. Thereby, it can prevent that a sliding door remove | deviates from the track | orbit of a guide rail. In order to prevent the sliding door from deviating from the track of the guide rail, a guide member such as a guide pin can be arranged instead of one guide rail in addition to providing the guide rail on both sides of the sliding door.

  The sliding door used in the sliding door device is preferably made of glass whose inside can be visually recognized. As the material of the glass, organic glass such as polycarbonate and polyacrylate can be used in addition to inorganic glass.

    As is apparent from the above description, according to the present invention, as a guide rail for guiding a sliding door whose cross section is curved in an arc shape, an elongated plate-like material having elasticity is formed by being bent by elastic deformation along the sliding door. Since a thing is used, even a curved sliding door can be moved smoothly.

The opening 4 is formed between the outer peripheral edge of the upper wall 2 and the outer peripheral edge of the lower wall 3. A sliding door device is installed in the opening 4.

  The sliding door device includes sliding doors 5 and 6 and a guide rail that guides the sliding door to move in the left-right direction. The sliding doors 5 and 6 are each made of a glass plate, and the opening 4 can be opened and closed by the two sliding doors 5 and 6. The sliding doors 5 and 6 are formed so as to be curved with a constant curvature in the left-right direction along the outer peripheral edges of the upper wall 2 and the lower wall 3. That is, the shape of the cross section of the sliding doors 5 and 6 is formed in an arc shape concentric with the arc center drawn by the outer peripheral edges of the upper wall 2 and the lower wall 3.

  In addition, between the sliding doors 5 and 6, it forms so that both curvature may differ. Specifically, the curvature of the sliding door 5 is formed to be slightly smaller than the curvature of the sliding door 6. That is, the sliding doors 5 and 6 are arranged concentrically with each other such that the sliding door 5 is on the outside and the sliding door 6 is on the inside. Thereby, both can be moved while drawing an arc in the left-right direction while pulling each other. The upper and lower ends of the sliding doors 5 and 6 are protected by a protective layer 9. The protective layer 9 is made of a synthetic resin, and for example, a vinyl chloride resin can be used.

  The sliding doors 5 and 6 are provided with guide rails for guiding each movement. Specifically, as a guide rail for guiding the sliding door 6, a guide rail (upper rail) 71 that is attached to the upper wall 2 and guides the upper end portion of the sliding door 6, and a lower end portion of the sliding door 6 that is attached to the lower wall 3. And a guide rail (lower rail) 72 for guiding. The guide rails 71 and 72 for guiding the sliding door 6 are arranged along the inner surface of the sliding door 6.

  Further, as a guide rail for guiding the sliding door 5, a guide rail (upper rail) 81 that is attached to the upper wall 2 to guide the upper end portion of the sliding door 5 and a lower end portion of the sliding door 5 that is attached to the lower wall 3 are guided. And a guide rail (lower rail) 82. Of the guide rails that guide the sliding door 5, the lower rail 82 is disposed along the inner surface of the sliding door 6, and the upper rail 81 is disposed along the outer surface of the sliding door 5.

  Each of the upper rails 71 and 81 and the lower rails 72 and 82 is formed by bending an elongated metal plate-like material by elastic deformation along the sliding door. Each rail is provided with a fixing portion for fixing the rail to the upper wall 2 or the lower wall 3. In addition, the front-end | tip part of each rail is return | folded so that a hand may not be cut in the cross section of a plate-shaped material.

  The lower rails 72 and 82 are each provided with a fixing portion 11 for fixing the rail to the lower wall 3. The fixing portion 11 is formed by fixing a metal fitting having a J-shaped cross section to the lower rails 72 and 82. A plurality of fixing portions 11 are provided at intervals in the left-right direction of the lower rails 72 and 82.

  The upper rails 71 and 81 are each provided with a fixing portion 12 for fixing the rail to the upper wall 2. The fixed portion 12 is formed by bending the upper rails 71 and 81 at one end in the width direction, and a plurality of fixed portions 12 are formed by cutting out the bent portions.

  Hereinafter, a method for installing the sliding door device of the present embodiment in the display case will be described with reference to the drawings. First, an upper rail 71 and a lower rail 72 that are guide rails for the sliding door 6 are installed in the display case 1. Specifically, as shown in FIG. 3, the curvature of the curved inner surface of the sliding door 6 is measured. Next, as shown in FIG. 7, the lower rail 72 is bent by elastic deformation so as to have the same curvature as the inner surface of the sliding door 6.

  The lower rail 72 is fixed to the lower wall 3 in a posture in which one end in the width direction is directed downward and the other end in the width direction is directed upward. Therefore, the fixed portion 11 is provided at the bottom of the lower rail 72 in an upright posture. A roller 13 for smoothly moving the sliding door 6 is integrally attached to the fixed portion 11. The fixing portion 11 is fixed to the lower wall 3 by a locking means such as a screw in the state where the lower rail 72 is curved to a predetermined curvature.

    The upper rail 71 is provided with a plurality of fixing portions 12 at one end in the width direction. This is bent by elastic deformation so as to have the same curvature as the inner surface of the sliding door 6. The upper rail 71 is curved so that the fixing portion 12 is radially outward.

  The upper rail 71 is made of a screw or the like while being curved to a predetermined curvature with the one end in the width direction (the side on which the fixing portion 12 is provided) facing up and the other end in the width direction facing down. The fixing portion 12 is fixed to the upper wall 2 by the locking means.

  With the upper rail 71 and the lower rail 72 installed in the display case 1 as described above, the sliding door 6 is arranged along these rails. As shown in FIG. 4, the sliding door 6 is placed on the plurality of rollers 13 of the lower rail 72, and the lower surface of the sliding door 6 is a rolling surface 6 a. Therefore, the sliding door 6 can be moved in the left-right direction with a light force.

  Next, as shown in FIG. 5, an upper rail 81 and a lower rail 82 that are guide rails of the sliding door 5 are installed in the display case 1. The installation method of the guide rail is the same as that for the upper rail 71 and the lower rail 72 described above. As shown in FIG. 2, the sliding door 5 is placed on the plurality of rollers 13 of the lower rail 82, and the lower surface of the sliding door 5 is a rolling surface 5a.

  When the upper rail 81 is curved, as shown in FIGS. 9A and 9B, the fixing portion 12 is inward in the radial direction, that is, opposite to the case of the upper rail 71. Curve in the direction of. Therefore, the curvature of the upper rail 81 is matched with the curvature of the outer surface of the sliding door 5. Thereby, when the display case 1 is viewed from the front, only the upper rail 81 can be seen and the fixing portion 12 cannot be seen, so that the aesthetic appearance is not impaired.

  As described above, the upper rail 81 is disposed on the outer surface side of the sliding door 5, and the upper rail 71 is disposed on the inner surface side of the sliding door 6. If it does so, there exists a possibility that the sliding door 5 and the sliding door 6 may contact. Therefore, in order to avoid such a situation, as shown in FIG. 1, the guide member 14 is installed between the upper rails 71 and 81 at the center in the left-right direction. As shown in FIG. 10, the guide member 14 has an E-shaped cross section.

  That is, the guide member 14 has a shape having two adjacent recesses. And as shown in FIG. 2, the upper end part of the sliding door 5 and the upper end part of the sliding door 6 are engaged with the guide member 14 for every recessed part. Thereby, the sliding door 5 and the sliding door 6 are prevented from coming into direct contact, and the sliding doors 5 and 6 can be smoothly moved in the left-right direction.

  In this embodiment, since the sliding doors 5 and 6 are curving in the left-right direction, they have independence. Further, the movement of the sliding doors 5 and 6 in the front-rear direction is restricted by the upper rails 71 and 81 and the guide member 14. Thereby, the sliding doors 5 and 6 do not have a possibility of wobbling or coming off from the guide rail when moving in the left-right direction.

  Moreover, as shown in FIG. 6, since the lower end part of the sliding door 6 is surrounded by the lower rails 72 and 82, it can prevent reliably removing from the guide rail 72. FIG. Further, on the front side of the lower rail 82 (the outer surface side of the sliding door 5), a cover material 15 for hiding the lower rail 32 is disposed. The cover material 15 is made of an elongated metal plate-like material like the guide rail, and is fixed by the locking means while being bent by elastic deformation. Thereby, since the lower end part of the sliding door 5 is enclosed by the lower rail 82 and the cover material 15, it can prevent reliably removing from the guide rail 82. FIG.

  Although the display case 1 demonstrated above was the aspect by which the some sliding doors 5 and 6 were distribute | arranged to the opening part 4, it is not restricted to this, For example, as shown in FIG. It is also possible to adopt a mode in which 5 is arranged. That is, in this aspect, the display case 1 is substantially cylindrical, and the opening 4 is formed in a part of the side surface 16. Then, as shown in FIG. 11, a lower rail 72 is formed on the lower wall 3 radially inward from the side wall 16. The sliding door 5 is disposed between the lower rail 72 and the side wall 16. An upper rail (not shown) is disposed on the upper wall. Thereby, the opening part 4 can be opened and closed even with one sliding door.
