Description

  The present invention relates to an entrance door such as an entrance door and a doorway door provided in a building such as a condominium, a building, a detached house, and an apartment house. In particular, it is an entrance door with disaster prevention measures suitable for entrance doors of high-rise apartments.

  When a fire breaks out in a condominium, building, detached house, etc., there are people who are late to escape and faint or unconscious, and there are places where people can go in and out, such as sweeping windows and entrances for entering and exiting the veranda. Very imminent situations often occur that remain locked. In such an emergency, if it is a one-story house or a general detached house, the fire brigade or rescue team can enter the interior relatively easily by breaking a glass window somewhere on the first floor. Can be done. Moreover, even if it is a building or a condominium, if it is a comparatively low floor, such as the 2nd to 5th floors, it is possible to break down the veranda or the window of the room by using a ladder car or the like.

  However, fires on high floors in high-rise buildings and high-rise condominiums that cannot be reached even by ladder cars cannot be entered through the windows on the veranda or outside, and can only be entered through the entrance. In such a case, the locked entrance door is cut using an engine cutter, and the door is managed to be opened. The lifesaving rate increases as the time after the fire breaks down, so the door break-out work for this moment must be done very quickly.

  In a normal swinging open / close type entrance door, there is a lock member straddling the door frame on the building side of the building and the door body near the keyhole for unlocking, so the operator can open the door body. A part close to the keyhole or handle at the side end is cut from the top to the bottom with an engine cutter. However, if the target location does not have a locking member, or the cutter blade slips and cuts away from the target location, the cutting operation will not work, and the cutting operation will be repeated several times. In many cases, the door breaking work using a power machine such as an engine cutter leaves room for improvement in order to speed up the work.

On the other hand, Patent Document 1 discloses an entrance door with an auxiliary door in which a small auxiliary door is provided on the door body of the entrance door. If such a structure is adopted for the entrance door of a building, even if the entrance door is locked in the event of a disaster such as a fire, it can break through the auxiliary door that is easier to break than the entrance door and enter the interior, Therefore, it seems that it is possible to substantially improve the efficiency of the door breaking operation.
JP 2004-137866 A

  However, the provision of the auxiliary door increases the door weight, increases the opening / closing load, and clearly increases the cost. In addition, since it seems that the appearance inside and outside the door is not good, the means for providing the auxiliary door which is hardly expected to be used has many disadvantages, and it is practically difficult to adopt. Therefore, in the event of a fire or when there is a seriously ill person to be rescued, there is room for further improvement in order to quickly break down the entrance door and other doors using a power machine such as an engine cutter. Was left behind.

An object of the present invention, apartments, by reviewing the structure of and out door building which is installed in a building or the like, and so such a portion including a locking member of the door can be cut to the engine cutters Thus in one shot, is locked It is to be improved so that it can contribute to the speeding up of the door break-through operation in a state where the door is in the open state.

The invention according to claim 1 is supported by the door frame 1 so as to be openable and closable, and a lock state in which the lock member 5s straddles the door main body 2H and the door frame 1 to maintain the door main body 2H in a closed posture; in the locking member 5s said door body 2H and and out door a for buildings wherein the unlocked state in which opening and closing movement is freely of the door body 2H to not span the door frame 1 is configured to be freely switchable, wherein In order to hide the lock member 5s in the locked state, the door body 2H is integrally provided with a blindfold plate portion 2B that covers a gap between the door body 2H and the door frame 1, and the blindfold plate portion 2B. The recess groove M set to a width dimension that allows the engine cutter blade 29 to be fitted in the outer surface of the upper and lower sides of the lock member 5s in the locked state, in the vertical direction, and on the upper side of the door body 2H. From And it is characterized in that it is formed with pierced in the side.

Invention, in the building and out door A according to claim 1, wherein the recessed groove M is folded by folding the sheet material are overlapped along the outer surface of the bottom plate member 35 to form a Mizosokokabe 35a according to claim 2 It is characterized by having groove side walls 31a, 36a formed by end faces.

The invention according to claim 3 is the locking device having the lock member 5s that is detachable with respect to the locking hole 22 formed in the door frame 1 in the building door A according to claim 1 or 2. 5 is provided in the door main body 2H.

According to the present invention, the door body in a closed position, which because indented portion indicating the whereabouts of the locking member to lock inhibiting locking kept open to the door frame is provided, the engine cutters when destroying and out door with, if cutting operation by applying a blade to the recessed groove, it is possible to perform door topped work by a single cutting operation. In other words, since the position of the lock member in the door is not determined by an approximate register or depending on the feeling, it is possible to reliably know the location of the lock member regardless of the skill level of this type of work. it can. As a result, a simple modification to the extent that put recessed groove in the door body, and so such a portion including a locking member of the door can be cut in one shot, the faster door topped work locked state by the engine cutters It was possible to provide a building entrance door that contributed.

In this case, the locking device for moving the lock member back and forth may be provided on the door main body or the door frame. However, if a general structure provided on the door main body is employed as in claim 3 , the door When breakthrough work is performed, it is possible to maintain the current state of the hole structure for inserting and removing the lock member provided on the door frame side, so there is an advantage that the entrance door can be restored only by replacing the door body. .

According to the first aspect of the present invention, there are further advantages as follows. That is, in the doorway, a blindfold projecting from the door body in order to improve the appearance by concealing the gap between the opening side end of the door and the door frame and the lock member being partially visible from the outside. A structure in which a plate portion is provided is employed. Therefore, in order to cut the lock member in the door with such a structure, there are many structural members, and the strength and rigidity of a single plate is lower than cutting with a door body having high strength and rigidity. It is easier to cut along with the blindfold plate part, and the door breakthrough operation can be performed in a short time. As a result, by devising providing the recessed grooves in the blind plate can pre SL functions and effects obtained better efficiency.

According to the present invention, furthermore, since recessed grooves are formed in the vertical direction transverse to the locking member, when cutting the door using the engine cutters may have a locking member with a short cut length It becomes possible to cut, and the door break-through work can be performed in a shorter time .

According to the first aspect of the present invention, the blade of the engine cutter can be inserted into the recessed groove when the door is cut, so that the blade is displaced from the planned cutting position when the engine cutter is driven and rotated. Therefore, it is possible to provide a building door that can cut the lock member portion of the door body more reliably.

According to the invention of claim 1 , it is possible to use the recessed groove not only as a display mark for a cut portion but also as a design for improving the appearance of the door. It is possible to provide an entrance door for a building that can achieve a synergistic effect.

According to the invention of claim 2 , since the bent end surface of the plate material is used as the groove side wall, it is possible to make the strength sufficient and, for example, means for forming a groove using an extruded material, cutting, The recessed groove can be formed at a lower cost than the means for forming a groove by processing. Since the folded end face is used for the groove side wall, the corner formed between the groove side wall and the groove bottom wall can be clearly formed, and a cutting tool such as a rotary blade can be used as the groove bottom wall. It is preferable that the groove can be sufficiently inserted, and the shape of the recessed groove can be clearly seen and can be made favorable in appearance.

These frame members 12 to 16 are made of, for example, the lower horizontal frame member 15 made of stainless steel, and the other frame members 12 to 14 and 16 are made of rolled steel plate materials. It is not limited. The right vertical frame member 13 and the intermediate vertical frame member 16 form a space S for passing a human body or luggage between them, and support the sealing members 18 and 19 made of a synthetic resin material such as rubber. Inner wall surfaces 13a and 16a having a slight width in the front-rear direction are formed.

  As shown in FIGS. 1 to 3, the door 2 is made of steel having a door body 2H, an end face material 2A on the open / close base end side, and a blindfold plate portion 2B on the open / close front end side, It is supported by the door frame 1 so as to be swingable and openable about a door fulcrum P via a support shaft 20 in a state extending between the upper and lower horizontal frame members 14 and 15. The end face material 2A is made of an extruded material having a curved door fulcrum side end face 2a having a semicircular cross section, and the interior space of the box-like door body 2H is filled with a soundproof heat insulating material 21 such as glass wool. ing. Further, the blindfold plate portion 2B that is integrally disposed and formed at the left end of the door main body 2H faces the substantially right half of the front surface of the intermediate vertical frame member 16 and the vertical gap between this and the door main body 2H. have.

  The intermediate vertical frame member 16 is configured with a receiving mechanism U in which a lock member 5s that is a retracting cylinder of the key 5 mounted on the door 2 can be inserted and removed. As shown in FIGS. 2, 4, and 5, the receiving mechanism U is inserted into the vertically long opening 22 (an example of a locking hole) 22 formed in the right front side wall 16 b of the intermediate vertical frame member 16 and the opening 22. A free box-shaped cover (tro-cover) 23, a base plate 24 bolted to the intermediate vertical frame member 16 from the outside of the box-shaped cover 23, and a thin box-shaped decorative cover 25 that is an exterior product covering the base plate 24 It is composed of Two nut portions 16n in total are formed at locations on the back side (indoor side) above and below the opening 22 in the intermediate vertical frame member 16.

  The box-shaped cover 23 has elasticity such as a spring plate having a box portion 23A with an open right side on which the lock member 5s can be inserted and removed and a pair of upper and lower mounting plate portions 23a folded up and down. It is formed of a plate material, and is dimensioned so that the box portion 23 </ b> A fits exactly into the opening 22 of the intermediate vertical frame member 16. The base plate 24 includes a support plate portion 24A in which an opening 24a through which the lock member 5s can be freely inserted is formed, and a pair of upper and lower mounting plate portions 24b positioned close to the box-shaped cover side. It is formed with. Nut portions 24n are formed on the upper and lower sides of the support plate portion 24A, and bolt insertion holes 24h are formed on the mounting plate portions 24b.

  The decorative cover 25 includes a top wall 25a having an opening 25k through which the lock member 5s can be inserted and removed, left and right side walls 25b (front and rear toward the entrance door), and upper and lower inclined walls 25c. It is comprised in the box-shaped thing with. Bolt insertion through holes 25h are formed on the top and bottom of the top wall 25a.

  As shown in FIGS. 4 and 5, the three members of the box-shaped cover 23, the base plate 24, and the decorative cover 25, first, attach the base plate 24 between the upper and lower sides between this and the right front side wall 16 b of the intermediate vertical frame member 16. After the mounting plate portion 23a is sandwiched, a pair of inner bolts (nabe screws) 26 are screwed into the nut portion 16n through the insertion holes 24h to be fixed to the intermediate vertical frame member 16 together with the box-shaped cover 23. That is, the box-shaped cover 23 is urged and supported by the pressing force generated by elastically deforming the pair of upper and lower mounting plate portions 23a. Then, a pair of mounting bolts (dish screws) 27 are screwed into the nut portion 24n through the through holes 25h, so that the decorative cover 25 is attached to the base plate 24 in a state of covering the box-shaped cover 23 and the base plate 24, that is, the intermediate vertical It is attached to the frame member 16.

  When the key 5 is locked with the door 2 closed, the locking member 5s passes through the opening 25k and the opening 24a so as to enter the box portion 23A of the box-shaped cover 23 (see FIG. 4). The door 2 is locked so as not to open from the closed state. When the lock release operation is performed on the key 5, the lock member 5s in the protruding lock posture is pulled back and switched to the retracted posture accommodated in the door body 2H, so that the door 2 can be freely opened and closed. That is, the lock member 5s straddles the door main body 2H and the intermediate vertical frame member (an example of a door frame) 16 so as to maintain the door main body 2H in a closed position, and the lock member 5s includes the door main body 2H and the intermediate vertical frame member. Thus, the door main body 2H can be freely opened and closed without straddling the door 16 so that the unlocked state can be switched. Even if the door 2 is opened and the intermediate vertical frame member 16 is exposed, the opening 22 is covered with a decorative cover 25 in an attractive manner, and the appearance of the receiving mechanism U is improved.

  As shown in FIGS. 4, 6 and 7, the lock member 5s is formed of a bent steel plate material having a downward open U-shaped side view formed of an upper wall 51 and a pair of left and right side walls 52, 53. In addition, a hook-shaped (sickle-shaped) retaining member 54 is provided between the left and right side walls 52, 53, and between the left and right side walls 52, 53. It is equipped so that it can be switched to the retracted attitude (position shown by a broken line in FIG. 6). The retaining member 54 is switched so that the lock member 5s switches to the working posture that projects downward as the lock member 5s switches to the projecting posture, and switches to the retracted posture as the lock member 5s switches to the retracted posture. The stop member 54 is linked to the lock member 5s. The retaining member 54 may protrude upward in the action posture.

  In a state in which the lock member 5s is switched to the projecting posture to lock the door 2, the retaining member 54 projects downward in the holder. For example, the door 2 and the intermediate vertical frame member 16 are used by using a tool such as a bar. Even if it is attempted to open the locked door 2 by forcibly widening the gap, the retaining member 54 is caught on the holder, so that the locking member 5s cannot be removed from the holder. Therefore, it is possible to cope with an unexpected situation in which the locked door 2 is forced to open, and the locking device contributes to further enhancing the locking effect of the door 2.

  For reference, FIG. 7 shows the positional relationship between the handles 6 and 37 inside and outside the door 2 and the upper and lower locking devices 5 and 5. Key holes 38 for locking and unlocking each locking device 5 are disposed at the upper and lower ends of the outer handle 6, and each locking device 5 is locked and unlocked at each of the upper and lower ends of the inner handle 37. A knob 39 that is rotated by a finger for unlocking is arranged. By pulling the outer handle 6, the door 40 (door main body 2H) can be opened and swung by moving the retractable hook 40 provided only in the upper locking device 5 to retract. Further, by pushing the inner handle 37, the hook 40 is moved back and forth to push the door 2 open and swing. In FIG. 7, the blindfold plate portion 2B is omitted.

  Next, the sleeve panel 3 will be briefly described. As shown in FIGS. 1, 2, and 4, the sleeve panel 3 is provided with upper and lower support shafts 28 centering on the panel fulcrum Q on the upper and lower sides of the front end portion at the left end portion of the hollow box-like panel material 4. The upper support shaft 28 is pivotally supported by the upper horizontal frame member 14, and the lower support shaft 28 supported by the lower horizontal frame member 15 is pivotally supported by the panel material 4. Further, the panel member 4 is formed with a thin plate portion 4 b that covers and hides the substantially left half of the front surface of the intermediate vertical frame member 16.

  A magnet catch 32, which is a mechanism that maintains the sleeve panel 3 in a closed state with respect to the door frame 1, that is, a working posture, is provided. As shown in FIGS. 2 and 4, the magnet catch 32 is provided on the front surface of the magnet 32a installed at the upper and lower intermediate positions of the right end portion of the panel member 4 and the left overhanging portion 16c of the intermediate vertical frame member 16 made of steel plate. The catch 32b made of a metal plate that is externally attached to the panel material 4 in a freely wearable state, and the catch 32b that receives the magnetic force of the magnet 32a is magnetically attracted to the intermediate vertical frame material 16 to thereby change the working posture of the sleeve panel 3. The energization can be maintained.

  With the magnetized force of the magnet catch 32, the sleeve panel 3 can be opened by strongly pulling it, but a lock mechanism 33 is also provided to keep the sleeve panel 3 from swinging and keeping it locked in the working posture. As shown in FIGS. 2 and 4, the locking mechanism 33 includes a locking bolt 34 that is screwed between the left front side wall 16 d of the intermediate vertical frame 16 and the right side wall 4 a of the panel member 4. As shown in FIGS. 4 and 5, the locking bolt 34 can be inserted into and removed from the intermediate vertical frame member 16 through the opening 22 for receiving the lock member 5 s of the key 5, and is equipped with a receiving mechanism U. In this state, the operation of the locking bolt 34 is not possible, and it is covered so that it cannot be seen from the outside. That is, the lock mechanism 33 has a structure in which the locking bolt 34 can be attached and detached using the presence of the receiving mechanism U, and the intermediate vertical frame member 16 does not require a dedicated bolt insertion hole.

Next, the disaster prevention structure of the door 2 will be described. As shown in FIGS. 1, 2, and 4, the outer surface 2h of the door body 2H is provided with a mark M indicating the location of the lock member 5s in the locked state. Specific configuration of the mark M, a recessed groove formed in the blind plate portion 2B in a state of penetrating the door 2 vertically, indented portion M in the vertical direction to the vertical direction transverse to the upper and lower pair of locking members 5s Are formed along. The recessed groove M is set so as to be in a positional relationship (the same positional relationship in the left-right direction) overlapping the gap between the opening / closing side end member 55 of the door body 2H and the decorative cover 25 in the front-rear direction. The groove width W is set to a value that is slightly larger than the thickness D of the rotary blade 29 of the engine cutter (not shown), that is, a dimension that allows the rotary blade 29 to fit into the recessed groove M. .

  The blindfold plate portion 2B is sandwiched between the folded portion end portion 31 of the outer surface plate 30 for forming the outer surface 2h of the door body 2H and the opening / closing side end member 55 as shown in FIGS. The bottom plate member 35 is fixed in a state in which the bottom plate member 35 is fixed, and the thick plate portion 36 is formed by folding the tip side portion of the bottom plate member 35. That is, the recessed groove M includes left and right groove side walls 36a and 31a formed by folded end surfaces of folded plate members that are overlapped along the outer surface of the bottom plate member 35 that forms the groove bottom wall 35a. . Since the groove side walls 36a, 31a are formed by the folded end faces of the plate material, the corners sk formed between the groove side walls 36a, 31a and the groove bottom wall 35a can be clearly formed and rotated. It is preferable in that the cutting tool such as the blade 29 can be sufficiently inserted into the groove bottom wall 35a, and thereby the shape of the recessed groove M can be clearly and clearly seen and can be preferable in appearance. It becomes. Moreover, as a two-ply structure of plate materials, each part is provided with sufficient strength and rigidity.

  For example, as shown in FIG. 9, in the means for forming the recessed groove M by press-molding the two-ply plate material portions B1 and B2 (which is within the scope of the present invention), a slight corner R appears at the corner portion sk. In addition to the tendency, the projecting angle portion tk on the groove opening side, which cannot be pressed by a direct mold, becomes a groove having a cross-sectional shape that is not clear due to large dripping (press dripping). Therefore, there is a disadvantage that even if the rotary blade 29 is fitted in the recessed groove M, it is easy to move and come out easily, and the appearance of the three-dimensional appearance is difficult because of the shape of the protruding angle on the groove opening side. There is also a disadvantage that gives. On the other hand, in the recessed groove M by the above-described folded end face, it is inexpensive due to the plate material and has the same thickness, but has a favorable appearance that is three-dimensional and clear without these disadvantages, and has been fitted. There exists an advantage which can guide the rotary blade 29 stably.

[Example 2]
The entrance door for a building according to the second embodiment relates to a general entrance door without a sleeve panel, and is shown in FIG. In FIG. 8, portions having substantially the same structure as the entrance door according to the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The entrance door A for building according to the second embodiment includes the door frame 1 and the door 2, and the lock member 5 s moves in and out with respect to the receiving mechanism U provided on the left vertical frame member 12.

  In this case, the recessed groove M in the blindfold plate portion 2B of the door 2 is set in a state of being positioned in front of the right end portion of the holder 41 constituting the receiving mechanism U. Accordingly, the lock member 5s is cut together with the holder 41 by the rotary blade 29 when the door breaks by the engine cutter in an emergency.

[Another Example]
In the entrance doors of the first and second embodiments, the door body 2H is equipped with a locking device 5 having a lock member 5s that can be inserted into and removed from a locking hole (opening) 22 formed in the door frame 1. However, the present invention can also be applied to an entrance door for a building in which a locking hole (opening) 22 through which the locking device 5 is installed in the door frame 1 and the lock member 5s is withdrawn is formed in the door body 2H. It is. In addition, the building entrance door can be applied to various doors such as a kitchen doorway, an entrance door that leads out from a washroom, and a sliding door door of a store. Further, the lock member 5s may be a rotary (rotating) type that can be used as either a swinging open / close door or a sliding slide door.

The “door frame” in the present invention refers to a fixed-side portion that supports the entrance door so that it can be opened and closed. As in the first embodiment, the entrance door has an openable and closable sleeve panel that is normally closed and locked. The “sleeve panel” and the “frame” in the structure in which the door frame is omitted and supported directly to the building frame so as to be opened and closed are defined as being included in the category of “door frame” .
