Description

  The present invention relates to a sliding door device for preventing a gap formed between a standing frame attached to the end of a building wall.

FIG. 5 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. 6 shows an enlarged cross-sectional view taken along the line AA of FIG. 5 above. 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.
Therefore, an airtight material (gap prevention material) such as mohair or packing with the same length as the gap (g) is attached to the side of the sliding door of the vertical frame (e), and the airtight material contacts the side of the sliding door. It was closing the gap (g) by doing.

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 “sliding door clearance prevention device” according to Utility Model Registration No. 3183840 is a technology previously devised by the applicant, and a concave groove is formed over the entire length of the sliding door side surface of the vertical frame. Fit a shielding member with a gap prevention member such as mohair that touches the sliding door surface at the tip, attach an adjustment member to the side of the entrance / exit of the vertical frame, and the adjustment member does not rotate into the hole provided in the vertical frame The outer ring fitted in this way and a rotating body that fits and rotates in the outer ring, and the shielding member moves forward and backward through the interlocking mechanism by rotating the rotating body.

As described above, there are various techniques for preventing the gap generated between the sliding door and the vertical frame. However, when there is a gap due to some cause (for example, sliding door warpage), the gap prevention member is moved by operating the adjustment member. In most cases.
"Sliding door structure" according to Japanese Patent Laid-Open No. 10-339077 “Neutral structure of sliding door” according to Japanese Patent Application Laid-Open No. 2009-127321 "Gap prevention device for sliding doors" according to Utility Model Registration No. 3183840

  As described above, the apparatus for adjusting the gap so that no gap is generated between the vertical frame and the sliding door has the above-described problems. The problem to be solved by the present invention is this problem, and when a gap is generated between the vertical frame and the sliding door, the shielding member having the gap preventing member is not operated by a person without operating the adjustment member. Provided is a clearance prevention device that can move naturally and close the clearance.

  The sliding door device targeted by the present invention has a sliding door that opens and closes an entrance formed between the left and right wall surfaces, and when the sliding door is closed, a vertical frame is provided at a position close to the door bottom side of the sliding door. Standing up, the basic structure is common with the conventional sliding door device. A recessed groove is formed over the entire length of the sliding door side surface of the vertical frame, and a shielding member is fitted into the recessed groove so as to be able to move forward and backward toward the sliding door surface. The shielding member has a base portion that fits into the concave groove, and a gap prevention member that is formed of mohair attached along the base portion or a soft elastic piece.

An elastic force is applied to the shielding member that fits into the groove, and the shielding member operates to protrude outward from the groove due to the elastic force. Therefore, the gap prevention member attached to the shielding member can always move forward and function so as not to cause a gap with the sliding door.
Here, the specific structure of the elastic member that urges the elastic force is not limited, but a plate spring, a coil spring, a resin spring, or the like can be used.

In the sliding door gap prevention device according to the present invention, a shielding member having a gap prevention member fitted in a recessed groove provided along the vertical frame is fitted, and an elastic force is urged on the shielding member. Therefore, the shielding member acts so as to protrude outward from the concave groove by the action of the elastic force. For this reason, the gap preventing member is in contact with the sliding door surface, and no gap is generated.
For example, even when the sliding door is warped and deformed with the passage of time or when the vertical frame is deformed, no gap is generated by the projection of the shielding member. That is, in the present invention, when a gap is generated, a person does not need to operate the adjustment member to advance the gap prevention member, and the shielding member naturally moves forward by the action of the elastic force to close the gap.

The sliding door is a deformed state of the hollow pipe when warped. Schematic which shows a general sliding door apparatus. AA sectional drawing of FIG.

  FIG. 1 is an embodiment showing an entrance / exit side of a sliding door device. In FIG. 1, 1 is a sliding door, 2 is a vertical frame, 3 is an upper frame, 4 is a lower frame, and 5 is a gap prevention member. Equivalent to. In a conventional general sliding door device, a gap is interposed between the sliding door 1 and the vertical frame 2. In the present invention, a gap preventing member 5 is attached to close the gap. Therefore, the form of the sliding door device targeted by the present invention is not particularly limited, and it can be a single-drawing type sliding door device, a double-drawing type sliding door device, or an upper rail attached to the upper frame. Even if it is a type of sliding door device in which a sliding door is suspended, a sliding door device of a type in which a sliding door is placed on a lower rail laid on a lower frame may be used.

By the way, the gap preventing apparatus according to the present invention is attached to the vertical frame 2 and can close the gap generated between the sliding door 1 and the vertical frame 2.
The gap prevention member 5 is not a member fixed to the cubic frame 2, but when the sliding door 1 is warped and deformed, or when the cubic frame 2 is warped and deformed, the gap preventing member 5 is moved forward by itself so as not to generate a gap between the sliding door surface. It is configured to be able to retreat. That is, there is no adjustment member that moves the gap preventing member 5 to close the gap when a gap occurs.

  FIG. 2 shows an enlarged cross-sectional view taken along the line BB of FIG. As shown in the figure, a recessed groove 6 is provided in the longitudinal direction on the sliding door side of the vertical frame 2, and a shielding member having a base 7 and a resin spring 8 is fitted in the recessed groove 6. And the mohair 9 used as one form of the clearance prevention member 5 is attached to the base 7, and the mohair 9 is in contact with the sliding door 1 with almost no gap. A resin spring 8 is integrally formed on the base 7 constituting the shielding member, and the elastic force of the resin spring 8 acts to push the base 7 outward (toward the sliding door).

  Therefore, the mohair 9 can be in contact with the sliding door surface, and even if the soft mohair 9 is in contact with the sliding door surface, the mohair 9 is not scratched with the opening / closing operation of the sliding door 1. Needless to say, the present invention is not limited to the mohair 9 as long as the gap preventing member 5 is made of a soft material that does not get scratched even if it slides in contact with the sliding door surface.

  FIG. 3 is a specific example showing a shielding member, and is an enlarged view showing a resin spring 8 formed integrally with the base 7. The resin spring 8 is constituted by a hollow pipe 10 having a substantially elliptical cross section, and this hollow pipe 10 is connected to the base portion 7 through a connection 11a, and is connected to the blade 12 through the connection 11b. Further, the blade 12 is connected to the blade 13 through a joint 11c. The joints 11a, 11b, and 11c are provided at the neutral portion of the base 7, the hollow pipe 10, and the blades 12 and 13, and the shielding member is formed as a long material having the same cross section as shown in the figure.

  An opening 14 is provided in the base 7, and a mohair 9 that is the gap preventing member 5 is fitted and attached to the opening 14. By the way, if a pressing force acts on the base portion 7 from above, the hollow pipe 10 is compressed and deformed and crushed. For this purpose, the hollow pipe 10 is made thin so that it can be easily compressed and deformed. Both the blades 12 and 13 have a width dimension so as not to be disengaged from the concave groove 6 when fitted into the concave groove 6 provided in the vertical frame 2. In addition, two convex pieces 15, 15 project downward from the bottom of the blade 13.

  Thus, the hollow pipe 10 constituting the resin spring 8 can be compressed and deformed. Therefore, when the hollow pipe 10 is compressed, the elastic force for restoring the original shape (substantially elliptical cross section) is obtained. Will occur. The resin spring 8 shown in FIG. 3 includes a single hollow pipe 10, but it is also possible to provide two hollow pipes 10 and 10 via a connection, in which case the amount of compressive deformation is doubled, The larger warping deformation of the sliding door 1 and the vertical frame 2 can be followed.

FIG. 4 is a specific example showing the change of the resin spring 8 when the gap with the sliding door 1 changes. (A) shows the case where the gap between the vertical frame 2 and the sliding door 1 is small, and (b) shows the case where the gap between the vertical frame 2 and the sliding door 1 is enlarged.
That is, when the initial setting is performed, the gap is small, and even when the sliding door 1 or the vertical frame 2 is warped and deformed, the gap 10 is enlarged by h, so that the hollow pipe 10 of the resin spring 8 is deformed. The tip of the mohair 9 can always contact the sliding door surface 16.

As described above, the thickness of the hollow pipe 10 is thin, so that it can be compressed and deformed by a small pressing force, and even if the sliding door 1 is slid open and closed with the soft mohair 9 in contact with the sliding door surface 16, it is scratched. There is nothing.
The long member shown in FIG. 3 in which the base 7, the hollow pipe 10, and the two blades 12 and 13 are connected via the respective joints 11 a, 11 b, and 11 c is integrally formed, and thus the manufacturing cost is reduced. Will be very cheap.

By the way, the elastic force for extruding the base portion 7 in the outward direction is not limited to the resin spring 8 described in the above embodiment. For example, it is also possible to accommodate a coil spring or a leaf spring in the concave groove 6 and to bias the elastic force to the base portion 7 by deformation of this spring.
In general, when the sliding door 1 is mounted, a gap prevention material 5 (for example, mohair) is set so that no gap is generated between the sliding frame 1 and the sliding door 1 or the vertical wall as time passes. Even if a gap is generated by warping deformation of the frame 2, the gap prevention member 5 is not adjusted each time.
However, in the present invention, adjustment of the gap prevention member 5 becomes unnecessary due to increase / decrease of the gap, and the gap prevention member 5 is adjusted by the action of the elastic force of the resin spring 8.
