Mode for Carrying Out the Invention

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an overall configuration example of a swing door 1 according to this embodiment, where (a) is a front view and (b) is a rear view.

[0010] As shown in FIG. 1, the swing door 1 of this embodiment includes a door plate 11 that can rotate (swing) in the front-rear direction (the direction in which people pass through) with respect to a door frame (not shown). This door plate 11 is rotatably attached to the door frame via an upper hinge 12 that rotatably supports the upper corner portion on the door butt side of the door plate 11 and a lower hinge 13 that rotatably supports the lower corner portion on the door butt side of the door plate 11. In the following description, the door butt side refers to the edge side that rotatably supports the door plate 11, and the door leading side refers to the free edge side where the door plate 11 opens and closes.

[0011] The positions of the upper hinge 12 and the lower hinge 13 are not aligned on the vertical axis and are installed at deviated positions. Thereby, the door plate 11 is configured to rotate around an inclined axis TAx connecting the position of the upper hinge 12 and the position of the lower hinge 13. With such a configuration, the door plate 11 rises and opens when pushed by a passerby, and the center of gravity is positioned higher when open than when closed. Then, when the passerby leaves the door plate 11, the door plate 11 automatically returns to the closed position by its own weight (a specific configuration regarding this will be described later with reference to FIG. 6).

[0012] The swing door 1 of this embodiment is provided with a display monitor 14 incorporated in the door panel 11. As shown in FIG. 1, the display monitor 14 is incorporated at a position closer to the upper side than the central position in the vertical direction of the door panel 11. The display monitor 14 is incorporated in the door panel 11 such that its display surface faces the front side shown in FIG. 1(a). Then, as shown in FIG. 1(b), the back surface of the display monitor 14 incorporated in the door panel 11 is blocked by the back cover 17. The details of the configuration regarding the incorporation of the display monitor 14 will be described later with reference to FIGS. 2 and 3.

[0013] Various information including content for guiding products and services, content for guiding various events, content for guiding discounts, sales, limited-time sales, etc., content related to trends and topicality, and content for guiding evacuation methods in the event of a disaster is displayed on the display monitor 14. The data for displaying this information is provided by communication from the outside. Thereby, it is possible to use the swing door 1 in which the display monitor 14 is incorporated as digital signage.

[0014] A window 15 is provided below the display monitor 14, and a spring bumper 16 is provided below the window 15. The spring bumper 16 is provided on both the front side and the back side of the door panel 11. The window 15 is configured, for example, by incorporating an acrylic plate having translucency into an opening formed in the door panel 11. The spring bumper 16 is formed, for example, by pressing a flat plate of a rigid resin material against a mold by a vacuum forming method or the like, and is formed to have a bent portion or a bent part at a portion biased toward the door tip side.

[0015] FIGS. 2 and 3 are diagrams showing a configuration example regarding the incorporation of the display monitor 14 into the door panel 11. FIG. 2 is an exploded perspective view of the swing door 1 viewed from an obliquely rear direction, and FIG. 3 is a partially enlarged view of a state in which the display monitor 14 is housed in the housing space 21.

[0016] As shown in FIG. 2, the display monitor 14 is a flat-panel monitor having a predetermined thickness. The display monitor 14 used in this embodiment does not have an electronic circuit module housed in a housing, and the electronic circuit module can be seen on the outside. Therefore, while the display surface on the front side is formed flat, the back side is not formed flat. In this embodiment, the flat-panel monitor means that although the back side is not flat, it is generally formed in a flat shape as a whole. The predetermined thickness of the flat-panel monitor refers to the thickness from the display surface to the most protruding part of the back surface. Note that a flat-panel monitor in which the electronic circuit module is housed in a rectangular housing may also be used.

[0017] As shown in FIG. 2, the door plate 11 has an accommodation space 21 having a predetermined size that is slightly larger than the planar size of the display monitor 14. The accommodation space 21 is configured by providing an acrylic plate 22 having translucency on the front end surface of an opening having a predetermined size formed in the door plate 11. Thereby, an accommodation space 21 having a depth approximately equal to the thickness of the door plate 11 is formed. The depth of the accommodation space 21 is approximately equal to the thickness of the display monitor 14, but it is not essential that they be exactly the same.

[0018] For example, the depth of the accommodation space 21 may be a value larger than the thickness of the display monitor 14. Alternatively, if the difference between the depth of the accommodation space 21 and the thickness of the display monitor 14 is within the thickness of the back cover 17, the thickness of the display monitor 14 may be a value larger than the depth of the accommodation space 21. The back cover 17 has a bottomed angular dish shape with a low height, and is configured to be able to accommodate a part of the display monitor 14 that protrudes outside the accommodation space 21.

[0019] The swing door 1 of the present embodiment includes a holding fixture 23 that is fixed to the door plate 11 while pressing a part of the back surface on the opposite side of the display surface of the display monitor 14 housed in the housing space 21. As shown in a partially enlarged view of FIG. 3, the holding fixture 23 is formed by bending a metal plate, and includes a fixing portion 23a that is a part that abuts against the door plate 11 and is fixed to the door plate 11, a holding portion 23b that abuts against or is close to the back surface of the display monitor 14 and presses the display monitor 14, and a support portion 23c that abuts against the side surface of the housing space 21 and serves to facilitate positioning.

[0020] The fixing portion 23a is a metal piece having substantially the same length as the long side of the housing space 21, and screw holes 24a are provided at a plurality of scattered locations. Screw holes 24b are also provided in the door plate 11 at positions facing the screw holes 24a of the fixing portion 23a. Thereby, with the fixing portion 23a in contact with the door plate 11, the holding fixture 23 is fixed to the door plate 11 by screws 25.

[0021] The holding portion 23b is a hook-shaped metal piece formed so as to bend from the fixing portion 23a, and abuts against or is close to a concave portion on the back surface of the display monitor 14. In the example of FIG. 3, three holding portions 23b of different sizes are provided. These holding portions 23b are formed in accordance with the position and size of the concave portion on the back surface of the display monitor 14. It should be noted that the position where the holding portion 23b is provided is preferably a position close to the end of the holding fixture 23.

[0022] The support portion 23c is a flat metal piece formed so as to bend from the fixing portion 23a, and has a role of facilitating positioning when the holding fixture 23 is fixed to the door plate 11 by abutting against the side surface of the housing space 21. Since positioning can also be performed by the holding portion 23b, it is not essential to provide the support portion 23c.

[0023] As shown in FIG. 2, a buffer material 26 is disposed in the gap between the side surface of the display monitor 14 housed in the housing space 21 and the side surface of the housing space 21. In the present embodiment, the buffer material 26 is disposed in the gaps between the three side surfaces (excluding the upper side surface) of the four side surfaces (upper, lower, left, and right) of the housing space 21 and the three side surfaces of the display monitor 14 housed in the housing space 21. The reason for disposing the buffer material 26 on the lower side surface among the four side surfaces is to take into account the gravity acting on the display monitor 14. The reason for disposing the buffer material 26 on the left and right side surfaces is to take into account the centrifugal force acting when the swing door 1 rotates.

[0024] As described above, since the swing door 1 of the present embodiment is configured such that the door plate 11 rotates around the tilt axis TAx, the door plate 11 is twisted during rotation. The display monitor 14 is incorporated into the door plate 11 having such properties. In the present embodiment, in order to reduce the physical load exerted on the display monitor 14 due to the twist of the door plate 11, the housing space 21 is formed to have a predetermined size slightly larger than the planar size of the display monitor 14, and the buffer material 26 is disposed in the gap between the display monitor 14 housed therein and the housing space 21. Further, the display monitor 14 is not completely fixed to the housing space 21 by screws or the like, but is only pressed by the pressing fixture 23. By configuring in this way, even if the door plate 11 is twisted when the swing door 1 rotates, the distortion force received by the display monitor 14 from the door plate 11 can be minimized.

[0025] Next, the configuration regarding the wiring to the display monitor 14 will be described. FIG. 4 is a diagram showing a configuration example of the wiring passage in the door plate 11. FIG. 4(a) is an exploded perspective view of the door plate 11 viewed obliquely from the back side, and FIG. 4(b) is a partially enlarged view of the core material 11b viewed from the back side.

[0026] As shown in Fig. 4(a), the door panel 11 of this embodiment is composed of a layer structure in which three face materials 11a to 11c are arranged opposite to each other and joined. The planar shapes of the three face materials 11a to 11c are the same, but their thicknesses are different. For example, the front face material 11a and the back face material 11c have the same thickness, while the core material 11b in the center is configured to be thicker than the front and back face materials 11a and 11c. For example, the thickness of the front and back face materials 11a and 11c is 9 mm, and the thickness of the core material 11b is 18 mm.

[0027] The three face materials 11a to 11c each have openings 21a to 21c with the same planar shape, and an accommodation space 21 is formed by the layer structure of these openings 21a to 21c. Further, the three face materials 11a to 11c each have openings 15a to 15c with the same planar shape below the openings 21a to 21c, and a window 15 is formed by the layer structure of these openings 15a to 15c.

[0028] Note that the materials of the three face materials 11a to 11c are arbitrary, and their joining methods are also arbitrary. For example, all of the face materials 11a to 11c may be wooden boards, and these may be bonded together with an adhesive. Instead of or in addition to the adhesive, they may be fixed using screws. Also, the core material 11b may be configured with resin, paper core, or foamed urethane, etc. For the front and back face materials 11a and 11c, steel plates may be used instead of wooden boards.

[0029] The core material 11b arranged in the center among the three face materials 11a to 11c is provided with a slit 41 for passing wiring from a part of the side surface to the accommodation space 21 (specifically, up to the opening 21b). The slit 41 is a through groove that penetrates from the front surface to the back surface of the core material 11b. On the other hand, no slit is formed in the front and back face materials 11a and 11c at positions facing the slit 41 of the core material 11b. Thus, when the three face materials 11a to 11c are bonded together, a wiring passage having the same thickness as the core material 11b is formed by the slit 41.

[0030] As described above, one end of the slit 41 is the opening 21b, and the other end is a part of the side surface of the core material 11b. In the present embodiment, the part of the side surface is a notch 42 formed on the door bottom side of the lower side surface. This notch 42 is the part where the lower hinge 13 is attached. That is, the slit 41 is formed from the end of the part where the lower hinge 13 is disposed to the accommodation space 21. In the present embodiment, further, a wiring passage is also formed in the lower hinge 13. Thus, the wiring passage is constituted by the lower hinge 13 and the slit 41 of the core material 11b.

[0031] FIG. 5 is a diagram showing a configuration example of the lower hinge 13. FIG. 5(a) shows an exploded view of two members constituting the lower hinge 13, and FIG. 5(b) shows a state where wiring is passed through the lower hinge 13. As shown in FIG. 5, the lower hinge 13 includes a door frame side hinge member 13a attached to a door frame (not shown) and a door plate side hinge member 13b attached to the door plate 11. The lower hinge 13 further includes a hinge cover 13c (see FIG. 2) covering the door frame side hinge member 13a, but this is not shown in FIG. 5.

[0032] The door frame side hinge member 13a has a base surface 51 fixed to the door frame and a sliding surface 52 provided at a position spaced upward from the base surface 51. A through hole 53 is provided in the sliding surface 52. The space between the base surface 51 and the sliding surface 52 is connected by a connecting portion 54 erected vertically from the base surface 51, and this connecting portion 54 is also fixed to the door frame. The connecting portion 54 is configured in a U-shaped cross section in order to provide sufficient strength to stably support the door plate 11 in which the display monitor 14 is incorporated.

[0033] The door panel side hinge member 13b has a U-shaped cross-section mounting portion 55 attached to the door panel 11 and a cylindrical rotating shaft 57 protruding downward from the base end surface 56 of the mounting portion 55. The rotating shaft 57 is inserted through the through-hole 53 of the door frame side hinge member 13a. Thus, the door panel side hinge member 13b is configured to rotate in the direction indicated by the arrow Y1 in Fig. 5(b) with respect to the door frame side hinge member 13a while sliding the base end surface 56 on the sliding surface 52 of the door frame side hinge member 13a.

[0034] The rotating shaft 57 is hollow, and the end portion on the base end surface 56 side of the rotating shaft 57 is configured to be positioned near the end portion of the slit 41 of the door panel 11 (core material 11b). Thus, as shown in Fig. 5(b), the wiring cord 100 can be passed from the door frame side hinge member 13a through the hollow portion of the rotating shaft 57 to the slit 41, and further led out to the display monitor 14 housed in the housing space 21 through the slit 41.

[0035] In this way, in the present embodiment, wiring is performed for the display monitor 14 through the wiring passage formed by the internal space provided near the end portion on the butt side of the door panel 11. Therefore, it is possible to draw in the wiring necessary for power supply and communication from the outside to the display monitor 14 in the housing space 21 in such a manner that the wiring is not disconnected or damaged due to the rotation of the door panel 11.

[0036] Fig. 6 is a diagram showing a configuration example of the upper hinge 12. The upper hinge 12 of the present embodiment is a hinge that suspends the upper corner portion on the butt side of the door panel 11 rotatably with respect to the door frame and has a function of automatically returning the door panel 11 from the open position to the closed position. Fig. 6 schematically shows an extracted configuration related to this auto-return function. Figs. 6(a1) and (a2) show the state when the door panel 11 is in the closed position, where (a1) is a front view and (a2) is a top view. Figs. 6(b1) and (b2) show the state when the door panel 11 is in the open position, where (b1) is a front view and (b2) is a top view. Figs. 6(a2) and (b2) show the configuration excluding the fixing member 61.

[0037] As shown in FIG. 6, the upper hinge 12 includes a fixing member 61 made of sheet metal formed in a substantially L shape. The fixing member 61 has a vertical portion 61a that extends in the vertical direction and is screwed to the inner surface of a door frame (not shown), and a horizontal portion 61b that extends in the horizontal direction and is screwed to the ceiling surface of the door frame. A vertical shaft 62 made of a round bar is provided downward on the lower surface of the horizontal portion 61b.

[0038] Near the lower end of the vertical shaft 62, a horizontal shaft 63 is passed in the front-rear direction, and a pair of rollers 64a, 64b are rotatably supported at both ends of the horizontal shaft 63. A cam plate 65 is also rotatably passed through the vertical shaft 62. The cam plate 65 is a member placed on the pair of rollers 64a, 64b, and as shown in FIG. 6(a1), it has a V-groove 65a that is recessed upward and flat portions 65b that extend horizontally on both the left and right sides thereof. The cam plate 65 is fixed to the door plate 11 via a connecting member (not shown). Thereby, the door plate 11 and the cam plate 65 rotate integrally.

[0039] When the door plate 11 is in the closed position, as shown in FIGS. 6(a1) and (a2), the pair of rollers 64a, 64b are fitted into the V-groove 65a. At this time, a force corresponding to the self-weight of the door plate 11 (accurately including the self-weight of the connecting member, the cam plate 65, etc.) acts downward on the pair of rollers 64a, 64b.

[0040] On the other hand, when the door plate 11 is pushed by hand and opened in the front-rear direction, the cam plate 65 rotates while riding on the rollers 64a, 64b according to the inclination of the V-groove 65a. Then, as shown in FIGS. 6(b1) and (b2), when the pair of rollers 64a, 64b are completely out of the V-groove 65a, the flat portion 65b on the lower surface of the cam plate 65 presses against the upper surfaces of the rollers 64a, 64b.

[0041] As described above, the door plate 11 rotates around the tilt axis TAx while gradually raising its center of gravity. That is, it gradually approaches the states shown in FIGS. 6(b1) and (b2) from the states shown in FIGS. 6(a1) and (a2). After that, when the door plate 11 is opened to an arbitrary position and then the hand is released from the door plate 11, the door plate 11 automatically returns to the closed position due to its own weight. That is, it gradually returns to the states shown in FIGS. 6(a1) and (a2). Thus, in this embodiment, the upper hinge 12 is configured to have an auto-return function. Therefore, as shown in FIG. 5(b), when the door plate 11 rotates, the door plate side hinge member 13b moves up and down in the direction of arrow Y2.

[0042] On the other hand, by holding the wiring cord 100 in a slack state in the space formed between the base surface 51 and the sliding surface 52 of the door frame side hinge member 13a, it is possible to avoid the influence on the wiring cord 100 due to the up and down movement of the door plate side hinge member 13b when the door plate 11 rotates.

[0043] As described in detail above, in this embodiment, a storage space 21 is provided in the door plate 11 that can rotate in the front-rear direction, and the display monitor 14 is incorporated into the storage space 21 to form the swing door 1.

[0044] According to this embodiment configured as described above, the swing door 1 with the display monitor 4 incorporated in the door plate 11 can be utilized as digital signage. The place where the swing door 1 of this embodiment is installed can be said to be a place facing the flow of pedestrians, a place where relatively many people use, or a place where pedestrians are likely to unconsciously look at. However, it has not been utilized as an installation place for digital signage so far. According to this embodiment, it becomes possible to utilize digital signage at a new and effective installation place, namely the swing door 1.

[0045] In particular, in the present embodiment, in order to incorporate the display monitor 14 into the door plate 11 that swings in the front-rear direction, the display monitor 14 is not completely fixed to the accommodation space 21 by screws or the like, but is only pressed by the pressing fixture 23, and a buffer material 26 is disposed in the gap between the display monitor 14 and the accommodation space 21. By configuring in this way, the physical load that the display monitor 14 receives from the door plate 11 when the door plate 11 rotates can be minimized.

[0046] Also, in the present embodiment, a slit 41 is provided in the central core material 11b among the three face materials 11a to 11c constituting the door plate 11, and a unique configuration is also adopted for the lower hinge 13, so that a wiring passage is formed near the end portion on the butt side of the door plate 11. Thereby, the wiring necessary for power supply from the outside and communication or the like can be drawn into the display monitor 14 in the accommodation space 21 in such a manner that the wiring is not disconnected or damaged due to the rotation of the door plate 11.

[0047] As configured above, the swing door 1 of the present embodiment may be attached to the door frame 71 in a state of being attached one by one as shown in FIG. 7(a), or may be attached to the door frame 71 in a state of being attached two by two as shown in FIG. 7(b). Further, as shown in FIG. 7(c), a configuration may be adopted in which the swing door 1 of the present embodiment and a normal swing door 72 without a display monitor are attached to the door frame 71.

[0048] Note that in the above embodiment, the configuration in which the door plate 11 includes the window 15 and the spring bumper 16 in addition to the display monitor 14 has been described, but it is not essential to include the window 15 and the spring bumper 16. For example, either one of the window 15 or the spring bumper 16 may be provided, or neither the window 15 nor the spring bumper 16 may be provided.

[0049] In addition, in the present embodiment, the upper hinge 12 and the lower hinge 13 are installed at positions shifted from the vertical axis so that the door plate 11 rotates around the tilt axis TAx. Also, an example in which the upper hinge 12 is configured by a hinge having an auto-return function has been described. However, the present invention is not limited to this. For example, the upper and lower hinges may be installed at aligned positions on the vertical axis, and the display monitor 14 may be incorporated into a swing door in which the upper hinge is configured by a normal hinge without an auto-return function. In this case, by configuring either the upper hinge or the lower hinge as shown in FIG. 5, a slit 41 may be formed in the core material 11b from the end of the portion where either the upper hinge or the lower hinge is arranged to the accommodation space 21.

[0050] Also, in the above embodiment, an example in which the display monitor 14 is incorporated into the door plate 11 has been described. In addition to this, a speaker may be incorporated.

[0051] The present invention also includes the embodiments shown in the following appendices.

[0052] 〔Appendix 1〕 〔Appendix 1〕 A door plate that is pivotally supported by an upper hinge at the upper corner so as to be rotatable and by a lower hinge at the lower corner so as to be rotatable, and is attached to the door frame so as to be rotatable in the front-rear direction, having an accommodation space for accommodating a flat monitor at a position spaced inward from the side surface, and a wiring passage for passing wiring from a part of the side surface to the accommodation space. The door plate for a swing door is characterized by the above.

[0053] 〔Appendix 2〕 The door plate has a layer structure in which three face materials are arranged opposite to each other. The core material arranged in the center of the three face materials has a slit for passing the wiring from a part of the side surface to the accommodation space, and the wiring passage is constituted by the slit. The door plate for a swing door according to Appendix 1 is characterized by the above.
