According to the conventional technique, the flexible shielding material is a soft synthetic resin material, a rubber material, or the like, so that it is not always sufficient in terms of durability and appearance, and there is room for improvement. There was a problem.

Therefore, an object of the present invention is to easily improve durability, appearance, etc. by combining a movable member urged via a spring material with an edge material on the door end side of the door in view of the problem of the prior art. The purpose is to provide a shielding structure for an inward opening door that can be made to stand.

The configuration of the present invention for achieving such an object is a left-right asymmetric channel-shaped edge material attached to the door end side of an inward-opening door, a movable member to be combined with the edge material, and a movable member directed toward the door frame. The movable member is provided with an urging spring material, and the movable member engages the outward engaging rib on the indoor side with the inward engaging rib on the upper edge of the indoor side of the edge material from the inside and the outdoor side. When the diagonally outward engaging rib is engaged with the diagonally inward engaging rib on the outdoor outer edge of the edge material from the inside to smoothly bulge the outer surface toward the door frame side, and when the door is closed, the door frame is closed. While forming an invisible gap between the door and the door, when the door is opened to the outside of the room, it comes into contact with the top of the outside of the door frame and is driven toward the edge material, allowing the door to open. And.

The edge material can be provided with a bottom cap at the lower end.

Further, the movable member may be provided with an end member at the lower end, and the end member may form screw holes and positioning pins corresponding to the indoor side and outdoor side screw pockets of the movable member, respectively.

Further, the spring material can urge the movable member diagonally from the center direction of the door to the outdoor side.

According to the configuration of the present invention, the movable member that forms an invisible gap with the door frame does not need to have flexibility and is formed of an edge material, an aluminum extruded shape material similar to the door frame, or the like. Therefore, there are no particular restrictions on its durability, appearance, and the like, and necessary and sufficient performance can be easily realized. The edge material and movable member do not interfere with the door frame when the door is normally opened and closed on the indoor side, and when the door is opened to the outdoor side in an emergency, only the movable member is on the outdoor side of the door frame. It shall interfere with the top of the door and be driven horizontally to the edge material side, and the edge material shall not interfere with the door frame. Further, when the door once opened to the outside of the room is returned to the normal closed position, it is not necessary to push the movable member back to the edge material side with a finger or the like, and it is only necessary to push the door back to the closed position. However, the outdoor top of the door frame means the top that appears on the outdoor side in the cross-sectional shape of the door frame.

The edge material can reliably hold the movable member in an appropriate position by supporting the lower end of the movable member to be combined via the bottom cap attached to the lower end.

When the end member is attached to the lower end, the movable member is seated on the bottom cap on the edge material side via the end member, and is harmfully twisted even when it comes into contact with the top of the door frame and moves to the edge material side. There is little risk of causing such problems. The end member can be fixed by easily and accurately regulating the relative posture with respect to the movable member by using the screw holes and the positioning pins corresponding to the respective screw pockets on the movable member side.

The spring material opens the door to the outdoor side by tilting the urging direction of the movable member diagonally from the center direction of the door to the outdoor side, and drives the movable member toward the edge material side via the top of the door frame. , The spring material can be properly compressed, and the opening operation of the door to the outdoor side can be smoothed. The inclination angle of the spring material in the urging direction with respect to the center direction of the door is extremely about 2 to 5 ° in consideration of related parameters such as the roundness of the surface of the movable member at the position where it contacts the top of the door frame. A small value is sufficient.

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

The shielding structure of the inward opening door is formed by attaching an edge material 11, a movable member 12, leaf springs 13, 13 ... As spring materials to the end surface of the inwardly opening door D on the door end side (FIGS. 1 and 2). .. However, FIGS. 2A to 2C are a schematic front view, a schematic side view of FIG. 2A, and a schematic enlarged cross-sectional view of FIG. 2B, respectively, as viewed from the door end side of the door D. , Only two leaf springs 13, 13 are shown in FIG.

The door D is supported on both the indoor side and the outdoor side so as to be openable and closable via a double-door hinge on the door tail side (not shown). The hinge always urges the door D to the indoor side, and the door D can be lightly locked to the closed position shown in FIG. The door end side of the door D in the closed position faces the door frame 21 at the tip of the wall panel P. Further, a slide bolt D1 on the indoor side and a handle D2 on the outdoor side are mounted on the door end side of the door D, and the slide bolt D1 is locked on the indoor side of the wall panel P to close the door D. The catch P1 to be locked is screwed. A reinforcing material P2 is incorporated in the wall panel P in order to improve the mounting strength of the catch P1. The slide bolt D1 can be switched between the locking position (solid line in Fig. 1) and the unlocking position (two-dot chain line in the same figure) from the indoor side, and in an emergency, a solution with a display incorporated in the handle D2. It is also possible to unlock from the outdoor side via the locking mechanism.

The edge material 11 is formed in a shallow left-right asymmetric channel shape that matches the thickness of the door D. Inward and diagonally inward engaging ribs 11a and 11b are formed on the indoor side and the outdoor outer upper edge of the edge material 11, respectively, and a leaf spring 13 having left and right guide ribs 11c and 11c is formed on the inner bottom surface. A mounting surface 11d for mounting is formed, and guide ribs 11e and 11e for mounting in the central portion and ribs 11f and 11f for seating at both ends are formed on the back surface side of the bottom surface. The mounting surface 11d for the leaf spring 13 is formed so as to be tilted outward by an inclination angle θ≈2 to 5 ° with respect to the central axis Cd of the door D.

The movable member 12 projects outward and diagonally outward engaging ribs 12a and 12b at both ends of the indoor side and the outdoor side, respectively, and has large and small diameter screw pockets inside both ends of the indoor side and the outdoor side, respectively. 12c and 12d are formed, the inner surface of the intermediate portion is formed on the contact surface 12e for the leaf spring 13, and the outer surface is formed by smoothly bulging. When the engaging ribs 12a and 12b are engaged with the engaging ribs 11a and 11b on the edge material 11 side from the inside and the movable member 12 is combined with the edge material 11, the contact surface 12e for the leaf spring 13 is an edge. It is parallel to the mounting surface 11d for the leaf spring 13 on the member 11 side, and the outer outer surface of the movable member 12 and the edge member 11 forms a smoothly continuous curved surface and faces the door frame 21.

The leaf springs 13, 13 ... Are jointly fastened downward to the mounting surface 11d of the edge material 11 via mounting screws 13a, 13a ... For fixing the edge material 11 to the end surface of the door D on the door end side. The leaf springs 13, 13 ... Are mounted between the edge member 11 and the movable member 12, and the movable member 12 is tilted toward the door frame 21 in the direction of the central axis Cd of the door D, that is, the inclination angle θ from the central direction of the door D. Only can be urged diagonally to the outside of the room. However, regardless of FIGS. 2A and 2B, the required number of leaf springs 13, 13 ... Is required for each approximately 300 mm pitch in the vertical direction of the door D, that is, in the length direction of the edge member 11 and the movable member 12. It is provided, and a spring material having an arbitrary shape other than that shown in the figure may be used.

A bottom cap 14 is attached to the lower end of the edge material 11 (FIGS. 2 and 3). However, FIGS. 3 (A) to 3 (C) are a schematic enlarged front view of a main part corresponding to FIG. 2 (A), a diagram corresponding to an arrow X in FIG. 3 (A), and a schematic main part corresponding to FIG. 2 (B), respectively. It is an enlarged side view. Note that FIG. 3 omits the illustration of the movable member 12 and the end member 15 at the lower end thereof.

The bottom cap 14 is formed by cutting out one corner of a rectangle and erection of a tongue piece 14b for attachment on the upper surface of a bottom plate 14a having a shape that follows the cross-sectional shape of the edge member 11. The tongue piece 14b is erected on the bottom plate 14a at an inclination angle θ which is the same as the mounting surface 11d for the leaf spring 13 of the edge member 11. Therefore, the bottom cap 14 is screwed to the lower end of the mounting surface 11d of the edge member 11 via the mounting screw 14d that is inserted into the screw hole 14c on the tongue piece 14b.

An end member 15 is attached to the lower end of the movable member 12 (FIGS. 2 and 4). However, FIGS. 4 (A) to 4 (D) are a schematic enlarged front view of the main part corresponding to FIG. 2 (A), a view corresponding to the Y arrow in FIG. 4 (A), and Z1 and Z2 arrows in FIG. 4 (A), respectively. It is a visual equivalent figure. Note that FIG. 4 omits the illustration of the edge material 11 and the bottom cap 14 at the lower end thereof.

The end member 15 has a bottom plate 15a having a shape substantially following the cross-sectional shape of the movable member 12 excluding the engaging ribs 12a and 12b, and screws so as to correspond to the large-diameter screw pocket 12c on the indoor side of the movable member 12. The hole 15b is formed, and the upward positioning pin 15c is erected so as to correspond to the small diameter screw pocket 12d on the outdoor side. Therefore, the end member 15 correctly regulates the relative posture with respect to the movable member 12 by press-fitting the positioning pin 15c into the screw pocket 12d and screwing the tapping screw type mounting screw 15d into the screw pocket 12c through the screw hole 15b. However, it can be fixed to the lower end of the movable member 12.

The edge member 11 and the movable member 12 are integrally formed of an extruded aluminum profile. Further, the bottom cap 14 and the end member 15 are integrally molded with, for example, polyethylene resin. The movable member 12 to be combined with the edge member 11 is supported by the end member 15 being seated on the bottom cap 14, and can be held at a predetermined height position.

The door frame 21 on the door end side of the door D has a top portion 21a on the outdoor side (FIG. 1), mounting legs 21b and 21b on the rear side, mounting legs 21c corresponding to the top portion 21a on the outdoor side, and seating on the indoor side. It is attached to the tip surface of the wall panel P via the rib 21d for the wall panel P. On the side of the door frame 21 facing the door D, from the indoor side to the outdoor top 21a, about 1/2 width or more of the indoor side is formed in a plane perpendicular to the wall panel P, and the rest is the top 21a. It is formed on a smooth curved surface toward. Therefore, at the closed position of the door D, the movable member 12 on the door D side can form an invisible gap g between the movable member 12 and the door frame 21 together with the edge member 11. However, about half of the outdoor side of the gap g is formed in a curved portion having a substantially constant width, and about half of the indoor side smoothly expands toward the indoor side. The door frame 21 is integrally formed of an extruded aluminum profile.

The operation of the shielding structure of the inward opening door having such a configuration is as follows, for example.

The door D in the closed position can be freely opened and closed indoors by unlocking the door D in the unlocked position (two-dot chain line in FIG. 1) with the slide bolt D1. At this time, the edge member 11 and the movable member 12 of the door D do not interfere with the door frame 21.

When the door D is in the closed position and the slide bolt D1 is locked in the locked position (solid line in FIG. 1), it is built into the handle D2 on the outside of the room in case of an emergency such as the user falling down. The door D is unlocked with the slide bolt D1 in the unlocked position via the unlocking mechanism, and then the handle D2 is pulled to open the door D to the outdoor side (directions of arrows in FIGS. 1, 5, and 6). ). At this time, if the door D is slightly opened to the outdoor side from the closed position of FIG. 1, the surface of the movable member 12 comes into contact with the top portion 21a of the outdoor side of the door frame 21, and when the door D is further opened (FIG. 5). The movable member 12 is driven toward the edge member 11 side against the leaf spring 13 via the top portion 21a, and the door D can be opened to the outdoor side (FIG. 6). However, FIG. 5 shows the time when the movable member 12 is most displaced toward the edge member 11 side by the top portion 21a, and the top portion 21a at this time is substantially on the extension of the center line (not shown) of the leaf spring 13. The surface of the movable member 12 can be pressed at the corresponding position, and the leaf spring 13 can be correctly compressed.

The door D in FIG. 6 may be further opened to the outside at an arbitrary angle to perform rescue work for the user in the room. On the other hand, the door D after a series of required operations can be returned to the original closed position by pushing it toward the room as it is. Also at this time, the top portion 21a of the door frame 21 comes into contact with the surface of the movable member 12 so as to ride relatively on the curved portion on the indoor side, and the movable member 12 can be smoothly driven toward the edge member 11. Because it can be done.

The present invention can be widely and suitably applied to inward-opening doors installed at entrances and exits of buildings for any purpose, such as toilet booths.
