  However, the configuration of the rack and the drive gear as in the known closer described above is intended for an upper suspension type sliding door, and since the rack and the driving gear are always meshed with each other, it can be applied to a lower door type sliding door. could not.

  Further, when the rack is disposed on the lower surface of the guide rail, the appearance of the rack is impaired because the rack is exposed.

  Further, in the closer by pulling out and rewinding the drive wire, the drive wire is exposed, and when the door is opened, when passing through the opening, there is a risk of being caught by the exposed drive wire, and the appearance is also impaired.

  An object of the present invention is to solve the above-mentioned problems and to provide a closer built-in type sliding door that corresponds to a lower door type sliding door, does not expose a drive wire, and does not impair the appearance of the sliding door.

In order to solve the above-mentioned problem, the invention according to claim 1 includes a main body case of a closer having a driving part and a braking part therein in an upper part of the sliding door, and is led out from the driving part in the opening direction of the sliding door. In the closed type sliding door provided with a drive wire fixed to the upper part of the opening of the building that houses the sliding door,
The sliding door is a lower door type sliding door provided with a nose that slides along the groove of the head of the opening, and a nose portion having substantially the same thickness as the nose is formed on the upper part of the main body case. And

  The invention according to claim 2 is characterized in that a concave portion is formed in the upper portion of the main body case to accommodate a fixing hook at the tip of the drive wire attached to the groove of the head when the door is closed.

  According to a third aspect of the present invention, the main body case is built in an intermediate portion of the upper part of the sliding door, and the door of the upper part of the sliding door on the side from which the drive wire is pulled out from the main body case is attached to the groove of the mower when the door is closed. A recess is formed to accommodate the fixed hook at the tip of the drive wire.

  According to the first aspect of the present invention, since the main body case is provided with the braking portion together with the drive portion, it is not necessary to provide a braking gear and a rack rail outside the main body case, and a lower door type sliding door is sufficient. Can be self-closed. Moreover, the closer built-in type sliding door can be installed only by exchanging the sliding door without exchanging the existing opening frame or the duck or performing additional processing.

  In addition, the closer body case is built in the sliding door, and the thickness of the upper nose of the main body case built in the sliding door is substantially the same as that of the sliding door. By attaching the tip of this drive wire in the groove of the Kamoi, the drive wire will be stretched in the groove and will not be exposed directly to the outside, which may impair the appearance of the sliding door by installing the closer. Absent.

  Furthermore, even in the case where the closer is built in, in the configuration in which it is stored and fixed under the nose portion of the sliding door, the portion corresponding to the closing door of the sliding door lacks the nose, so that light leaks from there and the appearance is not good. The closer has a nose that is continuous with the nose of the sliding door, and the nose and the closer are integrated, and there is no gap, so there is no light leakage, the appearance is not impaired, and the sliding door is not blurred. It is prevented and stable sliding door traveling can be secured.

  Furthermore, since the upper part of the closer fits in the groove of the headquarters, the pull-out position of the drive wire can also be arranged in the groove. Therefore, when the door is opened and passed, the drive wire is not directly touched by human eyes, so there is no danger of being caught by the exposed drive wire, and it is safe and the appearance of the opening is not impaired.

  According to the second and third aspects of the present invention, since the groove for receiving the fixed hook at the tip of the drive wire attached to the groove of the duck is formed, the fixed hook and the sliding door interfere with each other when the door is closed. The door can be closed smoothly.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1A and FIG. 1B are front views when the door with built-in closer 1 is opened and closed. A main body case 3 of the closer 2 is built in the upper part of the sliding door 1 and is housed in the main body case 3. The driven drive wire 4 is led out to the door end side of the sliding door 1 and fixed to the upper portion of the opening 5 of the building that houses the sliding door 1. When the door is opened, the drive wire 4 is drawn out. When the sliding door 1 is released, the drive wire 4 is pulled back and the door is automatically closed.

  The sliding door 1 is a lower door type sliding door provided with a door pulley (not shown) in the lower part, and a door neck 8 slidable in the groove 7 of the head 6 at the upper part of the opening 5 is provided along the opening / closing direction at the upper end. Is formed. And the storage space S of the main body case 3 of the closer 2 is formed in the upper corner | angular corner part of the door-end side of the sliding door 1 as FIG. 1 shows.

  A drive unit 10 and a brake unit 11 are provided inside the main body case 3 of the closer 2. The drive unit 10 includes a reel 12 around which the drive wire 4 is wound, and a drive spring 13 disposed inside the reel 12. The braking unit 11 includes a rotary damper 14 having a gear 16 formed on the outer periphery and a one-way clutch mechanism 17 disposed on the outer periphery of the output shaft 15. The gear 16 formed on the outer periphery of the rotary damper 14 is It meshes with a gear 18 formed on the back side of the reel 12. Thereby, when the drive wire 4 is unwound, the drive spring 13 is wound and the elastic restoring force is stored, and at this time, the rotary damper 14 idles integrally with the output shaft 15 by the one-way clutch mechanism 17, The braking force is not transmitted. When the drive wire 4 is released, the accumulated power of the drive spring 13 is also released, and the drive wire 4 is pulled back by the rotational force. At this time, the output shaft 15 of the rotary damper 14 is locked by the one-way clutch mechanism 17. The braking force is transmitted, and the rotation of the reel 12 is braked.

  Further, as shown in FIG. 3, the thickness of the upper part of the main body case 3 is formed substantially the same as that of the door 8 of the sliding door 1 and constitutes the door 20. A recess 21 is formed on the lead-out side of the upper drive wire 4, and the drive wire 4 is formed so as to be led out from the end of the recess 21. As shown in FIG. 2, a mounting stay 22 projects from the lower portion of the main body case 3. Further, a locking groove 23 is formed on the side wall opposite to the lead-out side of the drive wire 4.

  Next, when the closer 2 configured as described above is attached to the sliding door 1, a substantially L-shaped bracket 24 is screwed and fixed to the bottom of the storage space S of the sliding door 1 as shown in FIG. 2. The bracket 24 is arranged in the storage space S so that when the closer 2 is attached, the nose portion 20 of the main body case 3 is continuous with the nose 8 of the sliding door 1 (see FIG. 3). The upper end 25 of the bracket 24 is bent inward and the lower end 26 is bent downward. Next, the upper end bent portion 25 of the bracket 24 is locked in the locking groove 23 of the side wall of the main body case 3 of the closer 2, and at the same time, the mounting stay 22 of the main body case 3 is fixed to the lower end bent portion 26 of the bracket 24. The screw 27 inserted through the mounting stay 22 is screwed to the lower end bent portion. Furthermore, the cover 28 may be attached to the side end face side of the sliding door 1 of the main body case 3. The upper portion of the cover 28 is formed to have the same cross section as the concave portion 21 of the main body case 3. The surface of the cover 28 preferably has the same color tone as the side end surface of the sliding door 1.

  As shown in FIG. 3, the sliding door 1 is slidably attached along the sill of the opening 5 and the duck 6 of the building. At this time, the nose 8 of the sliding door 1 and the upper part of the main body case 3 are arranged in the groove 7 of the Kamoi 6. Further, the drive wire 4 is pulled out from the closer 2 attached to the sliding door 1, and the tip thereof is locked to a fixed hook 30 fixed to the upper bottom portion of the end portion of the groove 7.

  According to the above configuration, when the sliding door 1 is opened from the closed state of FIG. 1A as shown in FIG. 1B, the drive wire 4 of the closer 2 is pulled out from the main body case 3 when the door is opened. Ten springs are tightened. When the sliding door 1 is released, the driving wire 4 is drawn into the main body case 3 by the elastic restoring force of the mainspring, so that the sliding door 1 moves in the closing direction. At this time, the rotary damper 14 of the braking unit 11 operates to move at a suppressed speed so that the moving speed is not accelerated. Finally, the end surface of the sliding door 1 stops by hitting the side surface (door frame) of the opening 5, but the fixing hook 30 provided at the end of the opening 5 is accommodated in the recess 21 of the main body case 3. Therefore, the sliding door 1 does not interfere with the fixed hook 30.

  As described above, since the brake case 11 is provided in the main body case 3 together with the drive unit 10, there is no need to provide a braking gear and a rack rail outside the main body case 3, and the lower door type sliding door 1 is sufficient. Can be self-closed. In addition, the closer 2 built-in sliding door 1 can be installed only by exchanging the sliding door 1 without exchanging or adding an existing opening frame or the head 6.

  Since the body case 3 of the closer 2 is built in the sliding door 1 and the thickness of the upper neck portion 20 of the upper part of the body case 3 built in the sliding door 1 is substantially the same as the neck 8 of the sliding door 1, The drive wire 4 is led out from the door nose 20 and the drive wire 4 is stretched in the groove 7 by attaching the tip of the drive wire 4 to the groove 7 of the head 6 and directly to the outside. Is not exposed, so that the appearance of the sliding door 1 by the attachment of the closer 2 is not impaired.

  Further, even when the closer 2 is incorporated, in the configuration in which the door 2 is housed and fixed under the nose portion 20 of the sliding door 1, the portion corresponding to the closer 2 of the sliding door 1 lacks the nose 8, and light leaks from there. Although the appearance is not good, the closer 2 is formed on the closer 2 with the nose 8 of the sliding door 1, and the nose 8 and the closer 2 are integrated, and there is no gap, so there is no light leakage. Is not impaired, and sliding of the sliding door 1 is prevented, and stable sliding door travel can be secured.

  Furthermore, since the upper part of the closer 2 is housed in the groove 7 of the head 6, the pull-out position of the drive wire 4 can also be disposed in the groove. Therefore, the drive wire 4 is not directly touched by the human eye when the door is opened and passed, so there is no danger of being caught by the exposed drive wire 4 and it is safe and the appearance of the opening 5 is not impaired.

  In addition, if the thickness of the main body case 3 of the closer 2 is set to the same thickness as the nose 8 of the sliding door 1 as shown in FIG. 4, it is not necessary to bother to form the nose portion 20 in the main body case 3.

  The door 8 of the sliding door 1 is not necessarily formed at the center of the upper end surface of the sliding door 1. As shown in FIG. 5, the sliding door 1 may be formed at an offset position on one side of the upper end surface. In this case, the storage space S of the main body case 3 of the closer 2 may also be opened on the back surface of the sliding door 1, the main body case 3 may be fixed here, and the nose portion 20 may be continuous with the nose 8.

  In the figure, the same reference numerals as those in FIG. 3 denote the same members.

  Next, FIG. 6 shows another embodiment. In the main body case 3, a storage space S for the main body case 3 of the closer 2 is formed in the middle part of the sliding door 1, and the main body case 3 is stored in the storage space S. It is fixed. A recess 8 that accommodates a fixing hook 30 at the tip of the drive wire 4 attached to the groove 7 of the duck 6 when the door is closed is provided in the top of the sliding door 1 on the side where the drive wire 4 is drawn out from the main body case 3. 31 is formed.

  The main body case 3 is also provided with a door neck 20.

  According to the above configuration, the closer 2 is invisible from the outside except for the nose portion 20, and the nose portion 20 is hardly noticeable, so that the appearance of the sliding door 1 is hardly changed, but has a self-closing traveling function. Can do.

  Moreover, since the upper part of the closer 2 is housed in the groove 7 of the head 6, the pulling position of the drive wire 4 can also be arranged in the groove 7. Therefore, the drive wire 4 is not directly touched by the human eye when the door is opened and passed, so there is no danger of being caught by the exposed drive wire 4 and it is safe and the appearance of the opening 5 is not impaired.

  Furthermore, when the door is closed, the end surface of the sliding door 1 hits the side surface (door frame) of the opening 5 and stops, but the fixing hook 30 provided at the end of the opening 5 is accommodated in the recess 31 of the sliding door 1. Therefore, the sliding door 1 does not interfere with the fixed hook 30.
