Description

  The present invention relates to an apparatus for preventing a gap formed between a sliding door device and a vertical frame attached to a tip of a building wall.

  FIG. 10 is a schematic view showing a conventional general sliding door device. In the figure, (a) represents a sliding door, (b) represents a building wall, (c) represents a door pocket wall, (d) represents a sliding door frame, and (e) represents a vertical frame. The sliding door (A) shown in the figure closes the entrance (f), but if the sliding door (A) slides to the right, the entrance (F) opens. By the way, when the sliding door (I) is closed as shown in the figure, the doorway (F) is closed, but a gap (G) is interposed between the vertical frame (E) and the sliding door (I), There is a problem in that light leaks from the outside into the room through this gap (g), or a wind blows into the room, causing discomfort to people in the room.

  FIG. 11 shows an enlarged cross-sectional view taken along the line AA in FIG. 10. The upper ends of the sliding door frames (d) and (d) are connected by the upper frame (chi) and the lower ends are connected by the lower frame (re). The fitted frame is fitted in the opening formed between both walls (b) and (b). The upper end of the sliding door (I) is loosely fitted in the guide groove (N) of the upper frame (H), and the lower end of the sliding door (I) is placed on the rail (L) attached to the lower frame (Li). A gap (g) having a certain width is provided between the vertical frame (e) and the sliding door (a), and the sliding door (a) can be opened and closed without contacting the vertical frame (e).

However, this gap (g) is the clearance required to open and close the sliding door (a). Without this gap (g), the sliding door (a) contacts the vertical frame (e) and opens and closes. It becomes difficult and the surface of the sliding door is scratched. For this purpose, the gap (g) needs to have a minimum size so that the sliding door (b) and the vertical frame (e) do not contact each other.
For this reason, an airtight material such as mohair or packing having a length equal to the size of the gap (g) is attached to the sliding door measuring side of the vertical frame (e), and the airtight material is brought into contact with the side of the sliding door. (G) was blocked.

In this way, even if the airtight material is attached to the vertical frame (e), if the sliding door (a) warps, the gap (g) between the sliding door (a) and the vertical frame (e) increases. The airtight material cannot close the gap. Moreover, the gap (g) between the sliding doors (a) may be expanded by warping the vertical frame (e).
On the other hand, after installing the sliding door (I), the airtight material cannot close the gap (g) due to deformation of the frame due to the inclination of the building itself due to the earthquake, or generation of gaps (g) due to construction mistakes, etc. There are also many.

Therefore, conventionally, a technique has been developed that can cope with a case where the gap (g) generated between the sliding door (a) and the vertical frame (e) changes. For example, the “sliding door structure” according to Japanese Patent Application Laid-Open No. 10-339077 is provided with an insertion groove on the side surface of the sliding door and a base material and a closing body provided on the surface of the base material. A closing member that closes the clearance between the side surfaces of the uprights is inserted into an insertion groove provided in the upright so that the protruding amount can be adjusted.
By the way, the base material fitted in the insertion groove can be adjusted by screwing an adjusting screw from the surface of the closing material, so that the surface of the closing material is in contact with the sliding door surface. It is. That is, the sliding door must be removed and adjusted, and the sliding door must be mounted again to determine the clearance.

The “neutral structure of sliding door” according to Japanese Patent Laid-Open No. 2009-127321 is a neutral structure of a sliding door frame provided on a wall of a building and the like, which is easy to process and can reduce the manufacturing cost, and also has a small torque. It is a neutral structure with a compact and easy to handle sliding door that can move the gap adjustment member over a wide range.
Therefore, the gap adjusting member is formed with a long hole having a rack portion along the protruding and retracting direction of the gap adjusting member, and the neutral member is formed with an insertion hole corresponding to the long hole. A rotation adjusting member having a pinion portion inserted through the long hole and meshing with the rack portion of the long hole is provided.

By the way, if the rotation adjusting member having the pinion part rotates reversely after adjusting the gap adjusting member, a gap is generated between the sliding adjusting member and the sliding door. That is, the gap adjusting member is not stable at a fixed position.

The adjusting member includes an outer ring fixed to a vertical frame in a hole penetrating toward the concave groove, and a rotating body fitted to the outer ring so as to be rotatable. The outer periphery of the rotating body has an elastic claw that elastically engages with the concave and convex teeth. A rotary tool engaging groove is formed on the front surface of the rotating body, and an eccentric cam shaft is provided at the rear end of the rotating body. The eccentric cam shaft is a vertically long cam groove provided on the side surface of the shielding member. Is engaged.

In the sliding door clearance preventing device according to the present invention, the moving member is adjusted by moving the shielding member forward or backward in the sliding door direction by rotating the rotating member of the adjusting member from the side of the vertical frame using a rotary tool such as a screwdriver. I can do it.
That is, the eccentric cam shaft extending from the rear end of the rotating member of the adjusting member engages with the cam groove formed along the shielding member, and the eccentric cam shaft rotates with the rotation of the rotating member, so that the shielding member moves forward / You can retreat.

  And since the adjustment member is attached to the several places of a vertical frame, the protrusion amount of a shielding member can be changed with a place by adjusting the adjustment member of an appropriate location. Further, in the present invention, the rotation of the rotating body is prevented within the range of the elastic engagement force of the elastic claw by the meshing of the elastic claw of the rotating body and the concave and convex teeth of the outer ring. The shielding member does not reversely rotate in reverse and the gap prevention effect is not impaired. However, the lock mechanism of the rotating body is not limited to the elastic claw.
