Description

The present invention relates to the technical field of door devices that are installed at the entrances of buildings such as apartment buildings and homes.

Generally, in order to open and close the entrances and exits of buildings such as apartment buildings and houses, there are those that use a swing door system in which the door body swings open and closed in the indoor/outdoor direction with a vertical axis as the support axis. In this case, a hinge body is attached to the upper and lower edge of the door body, and the door body is attached so that it can be opened and closed freely via a pivot hinge (sometimes called a "corrugated hinge") in which the hinge axis is positioned offset from the hinge body in one of the indoor/outdoor directions.
However, when the hinge body of a pivot hinge is attached to the vertical edge of the door body, if the hinge body is attached to the visible surface of the vertical edge of the door body, the hinge body will protrude vertically from the visible surface of the door body and be visible from the outside, which is not desirable in terms of appearance.
Therefore, it has been proposed to form the above-mentioned vertical projected surface portions of the door body by bending the indoor/outdoor side panels of the door body inward in the indoor/outdoor direction, cut out the portions of the formed vertical projected surface portions corresponding to the hinge main body portion, and construct a structure in which the hinge main body portion is internally installed in the cut-out portion so that the hinge main body portion cannot be seen from the outside (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2007-138658

However, with the above-mentioned conventional products, the edges and corners of the cutouts created when forming the cutouts in the indoor and outdoor side panels are sharp and left exposed, posing a risk of injury if a hand or foot accidentally comes into contact with them. These are issues that the present invention aims to solve.

The present invention was created in view of the above-mentioned circumstances and with the aim of solving these problems. The invention of claim 1 is a door device in which a door body is journaled so as to be able to swing open and closed via a pivot hinge comprising a hinge body attached to the vertical edge of the door body and a hinge shaft positioned biased outward in the opening direction of the door body, and in which the projected surface portions of the vertical side edges of the door body are formed by bending the indoor and outdoor side panels inward in the indoor and outdoor direction at the vertical side edges of the door body, wherein cutout portions corresponding to the hinge body are formed in the projected surface portions of the vertical side edges so that the hinge body can be installed between the indoor and outdoor side panels, and a cover body provided to cover the hinge body is formed so as to extend beyond the cutout edges of the cutout portions in the projected surface portions and cover the outside in the indoor and outdoor direction.
The invention of claim 2 is a door device as described in claim 1, characterized in that the cover body is composed of an L-shaped plate material having a horizontal piece and a vertical piece, the horizontal piece is fastened to the projection surface portion at the door tip side portion beyond the hinge main body portion, and the vertical piece is fastened to the end surface portion of the door body on the door tail side.
The invention of claim 3 is a door device as described in claim 2, characterized in that the door body has a projected surface portion of the door body's door trailing edge edge formed by bending the door trailing edge side edge portion of the indoor/outdoor side panel inward in the indoor/outdoor direction, and the upper and lower edge portions of the projected surface portion of the door trailing edge side edge are covered by a corner portion between the horizontal piece portion and the vertical piece portion.

By adopting the invention of claim 1, the hinge main body provided on the door body has a cutout portion formed in the projected surface portion of the upper and lower side edges, and the hinge main body is installed between the indoor and outdoor side panels; and the cover body for covering the hinge main body extends beyond the cutout edge of the cutout portion in the projected surface portion and covers the outside in the indoor and outdoor directions.As a result, the cutout edge of the cutout portion is covered by the cover body for covering the hinge main body, and the cover body can be effectively used to prevent objects from getting caught on the cutout edge.
By adopting the invention of claim 2, the cover body is made up of an L-shaped plate material having a horizontal piece and a vertical piece, and the horizontal piece is fastened to the projection surface portion at the door tip side beyond the hinge main body portion, and the vertical piece is fastened to the end surface portion of the door body on the door tail side, thereby enabling the cover body to be securely attached.
By adopting the invention of claim 3, the upper and lower edge portions of the projected surface portion, which forms the end edge of the door body on the door tail side, are covered by the corner portion between the horizontal piece and the vertical piece of the cover body, thereby preventing objects from getting caught on the edge portions.

An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a door device (parent-child door device) installed at an indoor/outdoor (indoor/outdoor) doorway E. The door frame (door frame) constituting the door device 1 is configured as a rectangular frame with left and right vertical frames 2, 3 and top and bottom horizontal frames 4, 5. A main door (parent door) 6, which is operated for normal access through the doorway E, is attached to the vertical frame 3 on one side (the right side in FIG. 1 ) via a hinge 7 for the main door 6, and can be opened and closed in the front-to-back direction (indoor-to-outdoor, indoor-to-outdoor). Meanwhile, a sleeve door (child door) 9, which is normally kept closed via a general-purpose French lock 8 (described later), is attached to the vertical frame 2 on the other side via a hinge 10 for the sleeve door 9, forming a double-door opening and closing system. With this configuration, the vertical frame 3 on one side serves as the trailing vertical frame of the main door 6, and the vertical frame 2 on the other side serves as the trailing vertical frame of the sleeve door 9.
In the figure, reference numeral 1a denotes a door stop provided at the leading edge of the side door 9 on the indoor side so as to abut against the main door 6 when it is closed.

The main door 6 and the sleeve door 9 are provided with indoor and outdoor side panels (front and back panels) 11, 12, a filler 13 made of a core material such as a honeycomb core or a paper core filled between the indoor and outdoor side panels 11, 12, and a frame material 14 made of a frame material on the four peripheral edges of the main door 6 and the sleeve door 9. The main door 6 is supported via a pivot hinge 7, and the sleeve door 9 is supported via a center-hanging hinge 10, so that they can swing open and close freely toward the outdoors.
First, with regard to the sleeve door 9, the vertical frame member 14a on the door front side of the frame material 14 has leg pieces 14c, 14d extending from both indoor and outdoor end edges of the spanning piece 14b on the door tail side toward the door front, giving it an U-shaped opening on the door front side, but the indoor side leg piece 14c is longer than the outdoor side leg piece 14d, and indoor and outdoor side panels 11, 12 are attached to these indoor and outdoor leg pieces 14c, 14d from the outside in the indoor/outdoor direction, but the indoor and outdoor side panels 11, 12 are bent inward in the indoor/outdoor direction at the door front side edge portion of each leg piece 14c, 14d.

5, the indoor side panel 11 that is attached from the indoor side to the longer indoor leg piece 14c is bent toward the outdoor side at the leading edge (tip edge) of the indoor leg piece 14c, and this bent panel forms the leading edge visible surface 11a that becomes the leading edge of the sleeve door 9. Moreover, the indoor side panel 11 is bent further from the tip edge of the leading edge visible surface 11a toward the trailing edge to form the outdoor side panel 11b, and the tip edge of the outdoor side panel 11b is configured to reach a position closer to the trailing edge than the leading edge of the outdoor leg piece 14d.
With this configuration, a space S is formed at the leading edge of the sleeve door 9, surrounded by the U-shaped leading edge vertical frame member 14a and the leading edge visible surface portion 11a.
On the other hand, the outdoor side panel 12 is placed against the outdoor leg piece 14d from the outdoor side, and is bent from the tip edge of the outdoor leg piece 14d toward the indoor side so as to abut (or closely face) against the outdoor side portion 11b of the indoor side panel 11, thereby forming a step surface portion 12a that abuts against the outdoor side portion 11b in a step-like manner, and further forming a bent surface portion 12b that is bent from the step surface portion 12a toward the door tail side while following the outdoor side portion 11b.

The sleeve door 9 configured in this manner is provided with an intercom device 15 and a lighting fixture 16, which are exemplified as electrical and electronic appliances (electrical and electronic devices), exposed to the outdoors, but the wiring 17 for electrically connecting these intercom device 15 and lighting fixture 16 passes through a wiring pipe (through hole) 9a arranged inside the sleeve door 9 and is electrically connected by being arranged from the upper edge of the sleeve door 9 to the indoor side via a through hole 4a provided in the upper horizontal frame 4.
In this case, the upper edge of the sleeve door 9 is formed by stacking an upper frame member 14e that is U-shaped and open at the bottom, and upper visible surface portions 11c, 12c where the indoor/outdoor side panels 11, 12 are bent in the indoor/outdoor direction at their upper edge portions on a spanning portion 14g of the upper frame member 14e.A through hole 14f is formed in the upper edge of the sleeve door 9 configured in this manner, but the through hole 14f is semi-elliptical in shape and is long in the indoor/outdoor direction, and the arc-shaped edge on the outdoor side does not reach the outdoor leg portion 14j of the upper frame member 14e, while the edge on the indoor side is configured by cutting out the upper end of the indoor side leg portion 14h of the upper frame member 14e, including the corresponding portion of the indoor side panel 11.
When the sleeve door 9 is opened to the outdoors, the wiring 17 that passes through the wiring pipe 9a moves relative to the indoor side with respect to the through hole 14f that passes through it loosely. However, by maximizing this relative movement, when the wiring 17 abuts against the indoor side edge of the through hole 14f formed in the upper frame material 14e, the wiring 17 will not abut against the horizontal cutout edge 14k like the edge formed on the outdoor side of the spanning piece 14g, but will abut against the upward cutout upper end 14i of the indoor side leg piece 14h from the outdoor side. As a result, the risk of the wiring 17 abutting against the horizontal cutout edge 14k and suffering early abrasion damage is reduced, making it effective for sleeve doors 9 that are opened infrequently.

Furthermore, the French locks 8 are installed above and below the space S in the visible surface portion 11a on the door front side of the sleeve door 9. The French locks 8 are general-purpose locks that are locked by operating the operating device 8a up and down, causing the lock rod 8d to appear and disappear from the upper and lower edge portions of the sleeve door 9 and to fit into the lock holes 4b, 5b provided in the upper and lower horizontal frames 4, 5; further details will be omitted.
In this embodiment, the French drop lock 8 is fastened via a screw 8c to the door-end visible surface 11a where the operating device 8a is visible, and furthermore, the left and right outer surface portions of the French drop lock 8 are covered with a blocking plate 8b, thereby preventing the operating device 8a from being accidentally unlocked and the sleeve door 9 from being opened.
Incidentally, the cover for the closing plate 8b on the door-leading side visible surface portion 11a can be attached and detached by using a pop nut or by forming a tapped hole in the door-leading side visible surface portion 11a so that a screw can be screwed in, but in this embodiment the closing plate 8b is fastened with a screw 8e using a pop nut.

Furthermore, the sleeve door 9 is provided with a lock receiving portion (strike) into which the lock bolt of the locking device provided on the main door 6 fits. In this embodiment, two types of locking devices, a first locking device for the main lock and a second locking device for the auxiliary lock, are provided. Therefore, a first locking body portion 18 and a second locking body portion 19, which constitute the first (for the main lock) and second (for the auxiliary lock) locking devices, are provided above and below the edge of the door leading edge of the main door 6. The first body portion 18 operates by inserting a key (not shown) into the key hole portion 18a to operate the lock, and the deadbolt The first lock body 18 is equipped with a built-in locking mechanism in which deadbolt 18b extends and retracts to lock and unlock, and a locking mechanism in which latch bolt 18d, which is always protruding and locked when the operating handle 18c is operated, retracts to unlock, whereas the second lock body 19 is equipped with only a built-in locking mechanism in which deadbolt 19b extends and retracts to lock and unlock when a key is inserted into keyhole 19a and the lock is operated, but does not have a locking mechanism equivalent to the latch bolt 18d provided on the first lock body 18 side.

Since the first and second lock main bodies 18, 19 are provided on the main door 6 side in this manner, it is necessary to provide the first and second lock receiving bodies 20, 21 corresponding to these first and second lock main bodies 18, 19 on the side edge of the sleeve door 9, and for this reason the following considerations have been taken into account in this embodiment.
As mentioned above, the door-front side vertical frame member 14a of the sleeve door 9 is U-shaped, and a door-front side visible surface portion 11a is provided at the opening on the door-front side, where the tip portion of the indoor side panel 11 is bent.The first and second lock receiving portions 20, 21 are installed inside the space S formed by the vertical frame 14a and the door-front side visible surface portion 11a, and in this embodiment, the door-front side vertical frame member 14a has the door-front side visible surface portion 11a portion, where these lock receiving portions 20, 21 are actually attached, reinforced with reinforcing metal fittings 22.

The reinforcing bracket 22 is L-shaped in plan view, having a visible piece 22a and a recessed piece 22b, with the visible piece 22a welded (fixed) to the indoor leg piece 14c of the door-front vertical frame member 14a in a state where it abuts from the outdoor side, and the recessed piece 22b is arranged in a state where it abuts against the door-front recessed surface portion 11a of the indoor side panel 11 from the door tail side (back side).
Furthermore, the reinforcing metal fitting 22 is formed as an elongated member that spans between the first and second lock receiving portions 20, 21, and the projection piece 22b has first and second installation holes (installation grooves) 22c, 22d formed at the top and bottom for attaching the first and second lock receiving portions 20, 21. In this case, the first and second installation holes 22c, 22d are groove-shaped and open at the tip edge (outdoor edge) of the projection piece 22b.

The lock receiving portions 20, 21 differ in that the first lock receiving portion 20 receives both the deadbolt 18b and the latch bolt 18d, while the second lock receiving portion 21 receives only the deadbolt 19b, but in this embodiment they have the same structure, and therefore from here on, the first lock receiving portion 20 will be described in detail, and an explanation of the second lock receiving portion 21 will be omitted unless specifically necessary.
Incidentally, since the second lock receiving portion 21 only receives the deadbolt 19b, it can be made smaller than the first lock receiving portion 20, but this is something that can be changed as needed.

The first lock receiving portion 20 is configured to include an outer metal fitting 20a that is placed against and abuts the door-leading-side visible surface portion 11a of the indoor side panel 11 from the door-leading-side, and an inner metal fitting 20b that is placed against and abuts the visible piece 22b of the reinforcing metal fitting 22 from the door-tail side by providing the reinforcing metal fitting 22. As described above, the first lock receiving portion 20 is configured to be attached in a state in which the door-leading-side visible surface portion 11a and the visible piece 22b, which are arranged in a stack, are sandwiched between the outer metal fitting 20a and the inner metal fitting 20b, with the outer metal fitting 20a abutting the door-leading-side visible surface portion 11a and the inner metal fitting 20b abutting the visible piece 22b of the reinforcing metal fitting 22, by tightening the upper and lower end edges with screws 20c.
When the first lock receiving portion 20 is thus assembled into the sleeve door 9, the bent piece portion 20d formed by bending at the outdoor edge portion of the outdoor fitting 20a of the first lock receiving portion 20 is configured to cover the opening 22e formed in the first assembly hole 22c of the reinforcing fitting 22, thereby also serving to reinforce that portion.

On the other hand, as mentioned above, the upper edge of the main door 6 is pivotally supported by the upper horizontal frame 4 via the hinge 7 so that it can swing open and closed freely, and the lower edge is pivotally supported by the one side vertical frame 3 so that it can swing open and closed freely. The hinge 7 is a pivot hinge, and is composed of a door-side hinge half 7a provided on the main door 6 side, and a frame-side hinge half 7b provided on the door frame side.
The door-side hinge half 7a comprises a hinge main body 7c attached to both the upper and lower edge portions of the main door 6, and an extension portion 7d extending from the hinge main body 7c to the exterior side; when the door-side hinge half 7a is attached to the lower edge portion of the main door 6, a bearing hole 7e is provided in the extension portion 7d, and when it is attached to the upper edge portion, a hinge shaft 7f protrudes upward from the extension portion 7d.
In contrast, the frame-side hinge half 7b attached to the door frame side has a hinge shaft 7g formed in the frame-side hinge half 7b that corresponds to the lower door-side hinge half 7a and that fits into the bearing hole 7e, and the frame-side hinge half 7b that corresponds to the upper door-side hinge half 7a has a bearing hole 7h formed in which the hinge shaft 7f fits.

Of the hinges 7 configured in this way, the hinge body 7c of the door-side hinge half 7a attached to the top and bottom of the main door 6 differs only in whether the extension 7d is provided with a hinge shaft 7f or a bearing hole 7e. The attachment structure of the door-side hinge half 7a to the main door 6 is the same, albeit with a difference in the top and bottom (top and bottom). Therefore, from here on, we will only explain the door-side hinge half 7a attached to the lower side, and will omit explanations of the upper door-side hinge half 7a unless specifically necessary.

The hinge body 7c constituting the door side hinge half 7a has a rectangular shape that is long in the left-right direction, and an extension portion 7d is formed extending from the door end side of the long side on the outdoor side, and the hinge body 7c is fixed to the lower frame material 24.
Specifically, the lower frame material 24 is composed of a front-end frame portion 24a and a rear-end frame portion 24b, both of which are square-shaped with an opening at the top, and the front-end frame portion 24a is provided with a spanning portion 24c that extends to the lower edge of the sleeve door 9, and lower edge projection portions 11d, 12d, which are formed by bending the lower edges of the indoor and outdoor side panels 11, 12 inward in the indoor/outdoor direction, are attached to the spanning portion 24c using rivets 24d as fastening means.

In contrast, the trailing edge side frame portion 24b is arranged so that the spanning piece portion 24e is higher than the leading edge side frame portion 24a, thereby allowing the hinge main body portion 7c to be arranged in the space below the spanning piece portion 24e, with the indoor and outdoor sides surrounded by the indoor and outdoor side panels 11, 12.
The hinge main body 7c is placed on the spanning piece 24e from below and is fastened to a back plate 7i placed on the upper surface of the spanning piece 24e via a screw 7j. However, the back plate 7i is longer toward the door edge than the hinge main body 7c, and is configured so that the position of the hinge main body 7c can be adjusted by loosening the adjustment screw 7k that screws in from the spanning piece 24e.

The lower edge visible surface portions 11d, 12d of the indoor/outdoor side panels 11, 12 have cutout portions 11e, 12e formed by cutting out portions corresponding to the hinge main body portion 7c and the adjustment screw 7k, so that the hinge main body portion 7c and the adjustment screw 7k can be seen from below.As a result, the lower edge visible surface portions 11d, 12d have remaining cutout portions 11f, 12f in the portions extending from the inner edges of the cutout portions 11e, 12e to the front and back outer surfaces of the main door 6.
Furthermore, in this product, the lower edges 11h, 12h of the door tail edge side visible surface portions 11g, 12g of the indoor and outdoor side panels 11, 12 are in a state in which the cut-out edges at the lower edge side visible surface portions 11d, 12d are left exposed.
Furthermore, in this embodiment, the outer periphery of the extension 7d is covered with a covering material 26.

In this way, cutout portions 11e, 12e are formed on the lower edge side visible surface portions 11d, 12d with remaining cutout portions 11f, 12f remaining, and a cover body 25 for covering the hinge main body portion 7c is provided on the lower edge side visible surface portions 11d, 12d.
The cover body 25 is L-shaped and comprises a horizontal piece (lower piece) 25a and a vertical piece 25b, the horizontal piece 25a being wide enough to extend beyond the notch edges of the cutouts 11e and 12e and cover the remaining cutout portions 11f and 12f on the outside, and the leading edge of the horizontal piece 25a is fastened to the lower end projection surfaces 11d and 12d of the adjustment screw 7k using a rivet 25c as a fastener. Meanwhile, the vertical piece 25b is fastened to the trailing edge projection surfaces 11g and 12g of the trailing edge vertical frame member 27, which is U-shaped and has an open door leading end, using a rivet 25d as a fastener.
By attaching the cover body 25 to the main door 6 in this manner, the cover body 25 covers not only the cutout edges of the cutout portions 11e and 12e, but also the lower edges 11h and 12h of the visible surface portions 11g and 12g on the door tail edge side.

In the present embodiment configured as described above, the door device 1 is a double-door type having a main door 6 supported so as to be freely opened and closed via hinges 7, and a side door 9 supported so as to be freely opened and closed via hinges 10. In this case, the hinge 7 supporting the main door 6 is configured to have a door-side hinge half 7a and a frame-side hinge half 7b. The hinge body 7c of the door-side hinge half 7a is installed in a state where it is fitted to the lower edge of the main door 6 via cutouts 11e, 12e formed in the lower edge-side projection surfaces 11d, 12d formed by bending the lower edges of the indoor and outdoor side panels 11, 12. In this case, There is a risk that cutouts 11e, 12e could be left exposed and objects could get caught on them, but cutouts 11e, 12e are formed so that the cover body 25 provided to cover hinge main body 7c extends beyond the cutout edges of cutouts 11e, 12e and covers the remaining cutout portions 11f, 12f on the outside in the indoor/outdoor direction. As a result, the cutout edges of cutouts 11e, 12e are effectively covered by cover body 25 that covers hinge main body 7c, and the cover body can be effectively used to prevent objects from getting caught on the cutout edges.

In addition, the cover body 25 is made up of an L-shaped plate material with a horizontal piece 25a and a vertical piece 25b. The horizontal piece 25a is fastened to the projection surfaces 11d, 12d at the door leading edge beyond the hinge body 7c, and the vertical piece 25b is fastened to the projection surfaces 11g, 12g at the door trailing edge. As a result, the cover body 25 can be installed reliably and easily without being affected by the cutouts 11e, 12e.

Furthermore, the main door 6 has a projected surface portion of the door body's door trailing edge formed by bending the door trailing edge portion of the indoor/outdoor side panel inward in the indoor/outdoor direction, and the vertical edge portion of the projected surface portion of the door trailing edge is covered by the corner portion between the horizontal piece and the vertical piece.
Furthermore, in this case, the vertical edge portions 11h, 12h of the rear-end visible surface portions 11g, 12g of the main door 6 are covered by the corner portion between the horizontal piece portion 25a and the vertical piece portion 25b of the cover body 25, thereby preventing objects from getting caught on the edge portions 11h, 12h.

The present invention can be used as a door device that can be installed at the entrances of buildings such as apartment buildings and homes.
