Description

  The present invention relates to a flat sliding door having a flat front surface that can be suitably used, for example, as a front door of an upper cabinet of a counter or a sliding door with a mirror.

  2. Description of the Related Art Conventionally, for example, in a vanity table, various types of proposals have been proposed in Patent Document 1 below in which an upper cabinet is provided above a counter and a mirror is fixed to the front face of the front door of the cabinet.

  A vanity table with a cabinet with a mirror door above this type of counter can form a cabinet with a large storage volume inside the front mirror, so users can store many items such as toiletries and cosmetics. In addition, this type of vanity is widely used because it can be used conveniently just by opening and closing a door with a mirror.

On the other hand, in recent years, the vanity table has tended to increase in size, and as a result, the cabinet above the counter has also been increased in size. It will be mounted so that it can be opened and closed via. For this reason, the weight of the door is inevitably increased, and the hinges and cabinets that support it must be strengthened and the size of the cabinet must be increased. was there.
Japanese Patent Laid-Open No. 5-176851 JP-A-5-133157

  Therefore, it was considered to use the front door of the upper cabinet of the vanity as a sliding door, but when the front door of the cabinet has two left and right sliding doors and a mirror is fixed to each front, the two left and right sliding doors are Since there is a step in the front-rear direction, the two mirrors fixed to the step inevitably have a step, resulting in a problem that the two mirrors cannot be used as widely as a single mirror.

  For this reason, the adoption of a flat sliding door having a flat front surface as a sliding door was examined. As a flat sliding door, a structure in which the front surface of the sliding doors on both sides is flat when used in furniture and buildings and closed is proposed by the above-mentioned Patent Document 2 and the like. The flat sliding door has a complicated structure with a large number of parts, for example, it is necessary to displace a sliding member that crosses at an angle with respect to the guide groove of the guide rail. Depending on the use, there is a problem that the sliding part and the movable part are deteriorated, and the movement of the sliding door is easily hindered.

  The present invention solves the above-mentioned problems, and provides a flat sliding door that has a small number of parts, has a simple structure, can close the left and right sliding doors in a flat state, and can perform a favorable opening and closing operation. The purpose is to do.

  The flat sliding door according to the present invention is a flat sliding door having two sliding doors slidably mounted in the opening of the mounted portion, and a lower rail is horizontally attached to the lower portion of the front edge of the opening. The upper rail is attached horizontally to the upper part of the front edge facing the lower rail, and the lower rail and the upper rail are each formed with an upper rail groove and a lower rail groove stacked in two upper and lower stages. The upper rail is provided with a lower sliding member receiving recess and an upper sliding member receiving recess continuous with the upper rail groove, and with the lower sliding pin receiving recess and upper sliding pin receiving recess continuously with the lower rail groove. Is provided at the lower part of the two sliding doors, and a lower sliding member is provided to engage with an upper rail groove of the lower rail, and a lower sliding pin is provided on the lower rail. It is provided to engage with the lower rail groove of the An upper sliding member is provided to engage with the lower rail groove of the upper rail, and an upper sliding pin is provided to engage with the upper rail groove of the upper rail. When the sliding door is closed, the lower sliding member of each sliding door enters the lower sliding member housing recess from the upper rail groove of the lower rail, and the lower sliding pin extends from the lower rail groove of the lower rail to the lower sliding groove. The upper sliding member enters the upper sliding member housing recess from the lower rail groove of the upper rail, and the upper sliding pin enters the upper sliding pin from the upper rail groove of the upper rail. The two sliding doors are flattened by entering the storage recess.

  Here, in the said flat sliding door, a mirror can be fixed to the front surface of the sliding door of both sides, and when a sliding door is closed, a large mirror can be arrange | positioned in the flat state on the front surface. Further, if the lower sliding pin has a structure in which a steel ball is rotatably disposed at the lower end portion thereof, the frictional resistance during sliding can be reduced. Further, the lower rail, the upper rail, the lower sliding member, the lower sliding pin, the upper sliding member, and the upper sliding pin can each be molded from a synthetic resin, thereby improving the flat sliding door. While maintaining the opening and closing performance, the manufacturing cost can be greatly reduced as compared with a metal one.

  Further, when the lower rail and the upper rail are formed of a synthetic resin, the lower rail and the upper rail can be divided into a plurality of pieces in the longitudinal direction, formed as divided rail members, and assembled and laid so as to connect the divided rail members. Further, in this case, if each divided rail member is formed so that it can be used by cutting one side, the longest divided rail member is manufactured in advance by molding and rails laid in a cabinet or the like According to the length of each of the divided rails, one side of each divided rail can be cut and used, so that rails of various lengths can be manufactured at low cost with one type of mold.

  The flat sliding door of the said structure is slidably arrange | positioned at the opening front part of a cabinet, for example, A mirror is attached to the front surface of the both-sides sliding door, and it can be used as a flat sliding door with a mirror. When the sliding doors on both sides are closed, the lower sliding member of each sliding door enters from the upper rail groove of the lower rail into the lower sliding member housing recess of the rail front, and the lower sliding pin extends from the lower rail groove of the lower rail to the rail. The upper sliding member enters the upper sliding member housing concave portion of the upper rail from the lower rail groove of the upper rail, and the upper sliding pin enters the upper rail of the upper rail. It enters the upper sliding pin housing recess from the groove and stops. For this reason, since the two sliding doors are closed in a flat flat state, when the mirrors are attached to the front surfaces of the sliding doors on both sides, in the closed state where the sliding doors are not opened, the two mirrors on the front surface of the sliding doors are closed. As a flat state without a step, it can be used widely and conveniently like a single large mirror.

  On the other hand, when opening the sliding door, pull the outside of one sliding door toward you and push the inner side (center side) into the back, and the sliding door will be centered on the lower sliding pin and the upper sliding pin. Rotating to put the center side inward, whereby the lower sliding member enters the upper rail groove from the lower sliding member housing recess of the lower rail, and the upper sliding member is the upper sliding member of the upper rail It enters and engages with the lower rail groove from the storage recess.

  In this state, if one of the sliding doors is pulled into the back side of the other sliding door, the lower sliding member of the sliding door slides in the upper rail groove of the lower rail and advances to the open side, and the lower sliding pin The lower rail slides on the lower rail groove and advances to the open side, and the upper sliding member of the sliding door slides on the lower rail groove on the upper rail and advances to the open side, and the upper slide pin moves to the upper rail of the upper rail. Advance the groove to the open side. Thereby, one sliding door is accommodated in the back side of the other sliding door, and the front part of the cabinet is opened.

  The flat sliding door with the above configuration is composed of only the lower rail and the upper rail, and the lower sliding member and the lower sliding pin attached to the lower part of the sliding door, and the upper sliding member and the upper slide attached to the upper part. By simply engaging the pins with the rail grooves of the upper and lower rails, the pins can be easily mounted. In addition, since no auxiliary sliding member is used on the rail unlike the conventional flat sliding door, the number of parts is small, it can be easily assembled, and the deterioration of the sliding part due to use may be reduced. it can.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of a cabinet equipped with a flat sliding door. This cabinet is used, for example, as a cabinet disposed above a counter of a vanity, and a flat sliding door comprising two sliding doors 2 and 3 is provided at the front edge of the front opening of the cabinet. The rail 10 and the upper rail 20 are mounted so as to be able to run.

The sliding pin 9b is formed so as to be able to slide and engage with an upper rail groove 22 of the upper rail 20 described later, and can slide in the lower rail groove 22 with low friction. Further, similarly to the above, mounting holes for screwing the sliding doors 2 and 3 in the thickness direction and the vertical direction are formed in the mounting portion 9a.

  As shown in FIGS. 8 to 10, the lower rail 10 is engaged with the lower sliding members 6 and the lower sliding pins at the lower portions of the left and right sliding doors 2, 3 on the upper surface of the rail body. , 3 can be slid left and right. That is, the lower rail 10 has an upper rail groove 11 and a lower rail groove 12 formed on the upper surface of the long rail body, and a lower sliding member housing recess 13 and an end of the upper rail groove 11 and the lower rail groove 12. A lower sliding pin housing recess 14 is provided. The lower rail 10 can be integrally molded by molding a synthetic resin, and in the case of a long length, the lower rail 10 can be divided into a plurality of parts and molded together and fixed to the cabinet as one rail. it can.

  As shown in FIG. 8, the upper rail groove 11 is linearly formed along the longitudinal direction toward the inner side of the rail body, and is relatively wide and shallow as shown in FIG. Has been. The upper rail groove 11 is formed to have a width that allows sliding movement by the sliding portions 6 b of the lower sliding members 6 of the left and right sliding doors 2, 3, and is formed at a substantially central portion of the upper rail groove 11. 8-10, the lower sliding member housing recess 13 is formed at the same level as the groove 11 by shifting forward, and when the sliding doors 2, 3 are closed, the center of each sliding door 2, 3 is The sliding portion 6b of the lower sliding member 6 at the lower right end of the sliding door 2 on the left side, that is, the sliding portion 6b of the lower sliding member 6 at the lower left end of the right sliding door 3 is inserted therein. The structure is to stop.

  On the other hand, as shown in FIG. 10B, the lower rail groove 12 is formed along the lower side of the upper rail groove 11, and is shorter than the width of the upper rail groove 11 (sliding pin 7b is slidable). The sliding portion 6b of the lower sliding member 6 of one sliding door 2 or 3 and the sliding pin 7b of the lower sliding pin 7 of the other sliding door 3 or 2 are engaged with each other. It is slidable. Further, as shown in FIG. 8, both end portions of the lower rail groove 12 are shifted from the upper rail groove 11 and shifted to the front side at an intermediate position. A storage recess 14 is formed, and when the sliding doors 2 and 3 are closed, the sliding pin 7b of the lower sliding pin 7 at the lower center side of the sliding doors 2 and 3 is inserted and stopped.

  As shown in FIG. 8, the lower rail 10 is formed symmetrically about a center line passing through the center of the lower rail 10, and an upper rail groove 11, a lower rail groove 12, and a lower sliding member housing recess 13 formed on the upper surface. The lower sliding pin housing recess 14 is also formed symmetrically about the center line at the center.

  On the other hand, the upper rail 20 described later is formed in the same shape as the lower rail 10, and the lower rail 10 disposed in the lower portion and the upper rail 20 disposed in the upper portion are opposed to each other in a plane-symmetrical relationship. The upper rail 20 and the lower rail 10 are disposed at the upper and lower portions.

  That is, as shown in FIG. 11, the upper rail 20 is engaged with the upper sliding member 8 and the upper sliding pin 9 at the upper part of the left and right sliding doors 2, 3 on the lower surface of the rail body. , 3 can be slid left and right. That is, the upper rail 20 is formed with the lower rail groove 21 and the upper rail groove 22 on the upper surface of the long rail body, and the upper sliding member housing recess 23 is continuously formed at the end of the lower rail groove 21. Then, the upper sliding pin housing recess 24 is continuously formed at the end of the upper rail groove 22. The upper rail 20 has the same shape and structure as the lower rail 10, the upper sliding member 8 corresponds to the lower sliding member 6 of the lower rail 10, and the upper sliding pin 9 is the lower sliding of the lower rail 10. Corresponding to the pin 7, the lower rail groove 21 and the upper rail groove 22 correspond to the upper rail groove 11 and the lower rail groove 12 of the lower rail 10. Therefore, description of the detailed structure of the upper rail 20 will be omitted in place of the description of the lower rail 10.

  Since the upper rail 20 and the lower rail 10 have the same shape as described above, the upper rail 20 and the lower rail 10 can be manufactured and used as the same parts. Since the sliding member 6 and the upper sliding member 8 have the same shape, they can be manufactured as the same part and used together.

  The lower rail 10 configured as described above is fixed, for example, along the lower front end of the opening of the cabinet 1 installed above the counter of the vanity. Similarly, the upper rail 20 is located below the upper front end of the opening. It is fixed at a position facing the rail 10. Further, mirrors 4 and 5 are attached to the front surfaces of the left and right sliding doors 2 and 3, and a lower sliding member 6 and a lower sliding pin 7 are provided at the lower part of each sliding door 2 and 3, as shown in FIGS. The sliding portion 6b and the sliding pin 7b are engaged with the upper rail groove 11 and the lower rail groove 12 of the lower rail 10, respectively, and the sliding door 2 is attached using the mounting portions 6a and 7a and a fixing screw. , 3 is fixed to the lower part of the plywood body. Similarly, an upper sliding member 8 and an upper sliding pin 9 are provided on the upper part of each sliding door 2 and 3, as shown in FIGS. 12 and 13, and the sliding portion 8b and the sliding pin 9b are connected to the upper rail 20 respectively. In the state engaged with the lower rail groove 21 and the upper rail groove 22, it is fixed to the upper part of the plywood body of the sliding doors 2 and 3 by using the mounting portions 8 a and 9 a and fixing screws.

  And in the state which closed both the sliding doors 2 and 3, as shown in the uppermost part of FIG. 14, the sliding part 6b of the lower sliding member 6 of the lower part of the sliding doors 2 and 3 accommodates the lower sliding member of the lower rail 10. As shown in FIG. Located in the recess 13, the slide pin 7 b of the lower slide pin 7 is positioned in the lower slide pin housing recess 14 of the lower rail 10, and further the sliding portion of the upper slide member 8 above the sliding doors 2 and 3. 8 b is located in the upper sliding member housing recess 23 of the upper rail 20, and the sliding pin 9 b of the upper sliding pin 9 is located in the upper sliding pin housing recess 24 of the upper rail 20.

  In the lower rail 10 and the upper rail 20, the lower sliding member housing recess 13, the upper sliding member housing recess 23, the lower sliding pin housing recess 14, and the upper sliding pin housing recess 24 are located in the back. As shown in FIGS. 1 and 14, the sliding doors 2, 3 in the closed state are located at the front part of the rail, that is, the cabinet 1, because the grooves 11, 12, 21, 22 are shifted to the front part. It will be located in the most front part with the mirrors 4 and 5 being flat. Therefore, although there is a vertical boundary line at the center of the two mirrors, a very large mirror surface by the two mirrors 4 and 5 can be formed on the front surface of the cabinet 1.

  When opening such closed sliding doors 2 and 3, for example, when opening the left sliding door 2, as shown in the middle of FIG. At this time, the sliding door 2 is arranged so that the center side (right end) of the sliding door 2 is placed inside (inside the cabinet) with the sliding pin 7b of the lower sliding pin 7 and the sliding pin 9b of the upper sliding pin as axes. Turn slightly. As a result, the sliding portion 6 b of the lower sliding member 6 enters the upper rail groove 11 from the lower sliding member housing recess 13 of the lower rail 10, and the sliding portion 8 b of the upper sliding member 8 moves to the upper rail 20. The upper slide member housing recess 23 enters the lower rail groove 22 and engages.

  In this state, if the handle 2a of the sliding door 2 is pulled to the right, the lower sliding pin 7b slides in the lower rail groove 12 of the lower rail 10 as shown in the lower stage of FIG. While sliding in the upper rail groove 22 of the upper rail 20, the sliding portion 6 b slides right in the upper rail groove 11 of the lower rail 10, and the sliding portion 8 b moves in the lower rail groove 21 of the upper rail 20. Sliding in the right direction, the sliding door 2 moves to the right as shown in FIG. As a result, the left sliding door 2 enters and enters the inner side (rear side) of the right sliding door 3 and finally enters the ends of the lower rail 10 and the upper rail 20 as shown in the lower part of FIG. 2 stops in a state where it has completely moved inside the sliding door 3. As a result, the left front portion of the cabinet 1 is opened.

  On the other hand, when the sliding door 2 is closed, when the sliding door 2 is pulled to the left side with the handle 2a of the sliding door 2 from the opened state in the lower stage of FIG. 15, the lower sliding pin 7b of the sliding door 2 slides in the lower rail groove 12 of the lower rail 10. The upper sliding pin 9b slides in the upper rail groove 22 of the upper rail 20, the sliding portion 6b slides leftward in the upper rail groove 11 of the lower rail 10, and the sliding portion 8b By sliding the lower rail groove 21 of the upper rail 20 in the left direction, the sliding door 2 moves to the left side.

  When the sliding door 2 reaches the left end of the rails 10 and 20, the sliding pin 7b enters the lower sliding pin housing recess 14 from the lower rail groove 12 of the lower rail 10, and the upper sliding pin 9b is The upper slide pin accommodating recess 24 enters from the upper rail groove 22 of the rail 20. At this time, the state shown in the middle of FIG. Next, when the handle 2a is pushed slightly inward, the sliding door 2 is slightly rotated around the sliding pins 7b and 9b, and the sliding portion 6b of the lower sliding member 6 is the upper rail of the lower rail 10. The lower sliding member storage recess 13 enters from the groove 11, and the sliding portion 8 b of the upper sliding member 8 enters the upper sliding member storage recess 23 from the lower rail groove 21 of the upper rail 20 and stops.

  As a result, the two sliding doors 2 and 3 are completely closed and become a flat flat state. Therefore, in the closed state where the flat sliding door is not opened, the two mirrors 4 on the front surface of the sliding doors 2 and 3 are provided. 5 can be used widely like a single mirror, with a flat plate state without a step.

  FIG. 16 shows a flat sliding door (left sliding door) of another embodiment. This sliding door is formed as a metal frame sliding door 42, and a rectangular frame-shaped metal frame 42b is provided on the outer peripheral edge. A mirror 42c is attached to the inside of the metal frame 42b formed in a rectangular frame shape, but a panel other than the mirror can be attached to the inside of the metal frame 42b.

  And the upper sliding member 8 and the upper sliding pin 9 similar to the above are attached to the upper part of the metal frame 42b so as to protrude upward at a predetermined position. About the structure of the upper sliding member 8 and the upper sliding pin 9, since it is the same structure as the above, the description is abbreviate | omitted. Although not shown in FIG. 16, the lower sliding member 6 and the lower sliding pin 7 similar to the above are attached to the lower part of the metal frame 42b so as to protrude downward at a predetermined position. Although the right sliding door is not shown in FIG. 16, the right sliding door is formed in a shape symmetrical to the left metal frame sliding door 42.

  Similarly to the above, the metal frame sliding door 42 having such a structure is provided with the lower sliding member 6, the lower sliding pin 7, and the upper rail 20 on the lower rail 10 and the upper rail 20 that are attached above and below the front opening of the cabinet. The sliding member 8 and the upper sliding pin 9 are engaged so that they can be opened and closed. The sliding doors 42 are also opened and closed in the same manner as described above, and the front surfaces of the sliding doors 42 are flat with the sliding doors 42 on both sides closed.

  17-20 has shown the lower rail and upper rail of other embodiment. As described above, since the lower rail and the upper rail of the flat sliding door can be used together as the same rail, here, description will be given as the upper and lower rails 30 used as the upper and lower sides. Further, as described above, since the lower rail and the upper rail are formed symmetrically about the center line, only the left half of the upper and lower rails 30 is shown in FIGS. 17 to 20 because of the size of the paper. Omit the right half.

  That is, as shown in FIGS. 17 and 18, the upper and lower rails 30 are formed in three parts at the time of manufacture. As the molding material, a thermoplastic synthetic resin having good wear resistance such as an ABS resin is used, and each of the divided rail members 35, 36, and 37 is formed by molding a synthetic resin. The split rail member 35 at the left end is formed by providing the upper rail groove 31 on the upper surface, and a space is formed on the inner surface of the rear surface for removing the meat, and the ribs are vertically and horizontally in the space as shown in FIG. It is formed into a reinforcing structure. In addition, an insertion recess 35a for fitting the fitting protrusion 36a of the right adjacent split rail member 36 is formed at the right end of the split rail member 35. Furthermore, a fixing hole 35c for screwing and fixing a fixing screw is formed in the upper surface of the fitting recess 35a.

  The middle rail member 36 has an upper rail groove 31 formed on the upper surface thereof, and a lower rail groove 32 is formed as a deeper groove inside the upper rail groove 31 at a lower stage thereof. Continuing from the left end, a lower sliding pin housing recess 34 is provided on the rail member 36 by shifting forward. Further, a fitting convex portion 36a for fitting into the fitting concave portion 35a of the left-side divided rail member 35 is formed at the left end portion of the divided rail member 36. In addition, a fixing hole 36c is formed in the fitting convex portion 36a at a position corresponding to the fixing hole 35c.

  The distance S2 from the end of the fitting projection 36a of the fixing hole 36c is formed slightly shorter (for example, about 0.2 mm) than the distance S1 from the end of the fitting recess 35a of the fixing hole 35c. As a result, when the fitting convex portion 36a is fitted into the fitting concave portion 35a and a fixing screw is inserted into the fixing holes 35c and 36c to fasten and fix the rail, a gap is generated between the upper surfaces of the divided rail members 35 and 36. I am trying not to. In addition, the back side internal structure of the intermediate divided rail member 36 is also formed with a space for lightening, and reinforcing ribs are formed vertically and horizontally in the space.

  An insertion recess 36a is formed at the right end of the split rail member 36 to fit the fitting convex portion 37a of the right adjacent split rail member 37. Further, on the upper surface of the insertion recess 36a, A fixing hole 36d for screwing and fixing the fixing screw is formed.

  An upper rail groove 31 is formed on the upper surface of the right divided rail member 37, and a lower rail groove 32 is formed as a deeper groove on the inner side of the upper rail groove 31. A lower sliding member housing recess 33 is continuously provided on the rail member 37 so as to shift forward on the right side. Further, a fitting convex portion 37 a for fitting into the fitting concave portion 36 b of the left-side divided rail member 36 is formed at the left end portion of the divided rail member 37. In addition, a fixing hole 37c is formed in the fitting convex portion 37a at a position corresponding to the fixing hole 36d.

  The distance S2 from the end of the fitting projection 37a of the fixing hole 37c is formed slightly shorter (for example, about 0.2 mm) than the distance S1 from the end of the fitting recess 36b of the fixing hole 36d. As a result, when the fitting convex portion 37a is fitted into the fitting concave portion 36b and a fixing screw is inserted into the fixing holes 36d and 37c to fasten and fix the rail, a gap is generated between the upper surfaces of the divided rail members 36 and 37. I am trying not to. In addition, the back side internal structure of the rightmost divided rail member 37 is also formed with a space for lightening, and reinforcing ribs are formed vertically and horizontally in the space.

  The upper and lower rails 30 including the divided rail members 35, 36, and 37 configured as described above are mounted as horizontally facing the upper and lower portions of the front opening of the cabinet, for example, as a flat sliding door rail. . In other words, the upper and lower rails 30 are attached upward on the lower rail, and the same upper and lower rails 30 are attached downward on the upper rail.

  When the upper and lower rails 30 are attached to the cabinet, the divided rail members 35, 36, and 37 are connected in a row as shown in FIGS. 17 and 18 and fixed by fixing screws. When fixing, the fitting protrusion 36a of the middle divided rail member 36 is fitted into the fitting recess 35a of the left divided rail member 35, and the right divided rail member 37 is fitted into the fitting recess 36b of the middle divided rail member 36. The convex portion 37a is fitted, and a fixing screw (not shown) is inserted into the fixing holes 35c, 36c, and 36d, 37c of the connecting portion, and fixed so as to be screwed into the cabinet side frame.

  In this way, the upper and lower rails 30 are divided into a plurality of divided rail members 35 to 37, so that a large molding die is not required and, as will be described later, the maximum length rail is provided. If it is manufactured in advance, a rail having a length within that range can be easily manufactured by cutting and joining the divided rail members to an appropriate length.

  That is, as shown in FIGS. 20A and 20B, when a shorter upper or lower rail 300 or 301 is required, the right end of the left split rail member 35 is cut by an arbitrary length, and similarly, The right end of the divided rail member 36 is cut by an arbitrary length, and they are connected and used in the same manner as described above. As described above, since the space inside the back surface of the split rail members 35 and 36 is formed with ribs, the insertion recesses similar to the insertion recesses 35a and 36b are formed at the cut end portions after cutting. Can be formed. In this way, if the upper and lower rails are divided into a plurality of divided rail members and the ends of each divided rail member are cut and connected to each other, the maximum length of the upper and lower rails can be manufactured in advance. By setting the lower rail, the upper and lower rails having a shorter length as shown in FIGS. 20 (a) and 20 (b) can be obtained by cutting the ends of the divided rail members and connecting them. 300 and 301 can be manufactured easily and inexpensively.
