Description

The present invention relates to a door panel.

A door panel has been known in the past in which a pull member is attached to one side of the door thickness direction of the vertical frame of the panel body, which has a plate-like member such as a translucent member provided within the frame on all four sides. In such door panels, there was a concern that if the dimension along the door width direction of the vertical frame becomes small, it will be difficult to attach the pull member to one side of the vertical frame in the door thickness direction.
For example, the following Patent Document 1 discloses a mounting structure for a handle that is provided with an engaging wall surface that engages with a bead mounting protrusion provided in a glass fitting groove of a vertical frame, and is fitted into the glass fitting groove for installation. Two finger hooks are protruding from the surface of the handle opposite the glass side of this mounting structure for placing fingers.

Japanese Utility Model Publication No. 58-56293

However, with the mounting structure described in Patent Document 1, finger grips protrude from both sides of the handle in the door width direction, which raises concerns that the handle's dimension along the door width direction may become large.

The present invention was made in consideration of the above situation, and aims to provide a door panel that allows a pull member to be attached to a vertical frame with a small dimension along the door width, while also enabling the pull member's dimension along the door width to be reduced.

To achieve the above objective, the door panel of the present invention comprises a panel body with plate-shaped members mounted within a frame on all four sides, and a pull member attached to at least one side of the door thickness direction of the door leading end of the panel body. The pull member is characterized by having a handle portion that extends in the door height direction from the inner surface of the panel body's vertical frame on the door leading side facing the door trailing end at a position spaced from the door trailing end, and that defines both sides of the finger receiving recess in the door width direction with the inner surface, and a fixing portion that extends from both ends of the handle portion in the door height direction toward the door leading end and is fixed to the vertical frame.

The door panel of the present invention, with its configuration as described above, allows the pull member to be attached to a vertical frame with a small dimension along the door width, while still allowing the pull member's dimension along the door width to be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
In some drawings, some of the detailed reference numerals used in other drawings are omitted.
In the following embodiment, directions such as the up and down directions will be described based on the state in which the door panel according to this embodiment is installed.

1 to 5 are diagrams schematically showing an example and a modified example of a door panel according to the present embodiment.
As shown in FIG. 1( a), the door panel 1 according to this embodiment includes a panel body 2 having a plate-like member 3 provided within a four-perimeter frame (four-perimeter frame) 6, and a pull member 20 attached to at least one side of the door-thickness direction of the door-front end of the panel body 2. The door panel 1 may be erected as a sliding door, for example, by connecting a runner suspended from an upper rail to the upper end of the panel body 2. In this case, a guide groove into which a guide pin provided on the floor or an adjacent door panel is inserted may be provided at the lower end of the panel body 2. The door panel 1 is not limited to being suspended from an upper rail, but may also be erected in a configuration in which a door roller or the like that travels on a floor-side travel object is provided at the lower end. The door panel 1 is not limited to being erected in a single-sliding manner so as to open and close an entrance using only the door panel 1, but may also be erected in a sliding or double-sliding manner so as to open and close an entrance using another door panel 1.

The panel body 2 is a roughly rectangular flat plate that is long in the vertical (door height) direction. The door height dimension (length dimension) of this panel body 2 may be set to correspond to the opening height of the doorway opened and closed by the door panel 1. The door height dimension of this panel body 2 may be, for example, approximately 1800 mm to 2100 mm, or may be approximately the same height as the ceiling height from floor to ceiling, for example, approximately 2400 mm to 3000 mm. The width dimension of the panel body 2 may be set appropriately to correspond to the opening width of the doorway, depending on the number of door panels 1 that open and close the doorway, and may be, for example, approximately 600 mm to 1200 mm.

Like the panel body 2, the plate-shaped member 3 is a generally rectangular flat plate elongated in the vertical direction. The plate-shaped member 3 is formed from a translucent material such as glass or a synthetic resin material such as acrylic or polycarbonate, and is a light-transmitting plate. In other words, the plate-shaped member 3 constitutes a lighting section. The plate-shaped member 3 may be, for example, laminated glass formed by joining two glass plates together in the thickness direction. The plate-shaped member 3 is not limited to being substantially colorless and transparent, but may also be colored and transparent or translucent. The plate-shaped member 3 may be, for example, a transparent material to which a colorant is added, or may be colored and transparent by laminating a resin film or the like. The plate-shaped member 3 may be smoked glass or frosted glass, or may be configured by sandwiching a sheet material such as Japanese paper between two transparent (translucent) panels. The plate-like member 3 may be a half-mirror, or may have mirrors on both sides in the thickness direction, or may be an opaque plate. Furthermore, both sides in the thickness direction are not limited to being substantially flat, and may have irregularities.

As shown in Figures 2(a)-(c), the plate-shaped member 3 is held in place by its four peripheral ends 3a being inserted into receiving grooves 15 provided in the peripheral frame 6. While Figure 2 only shows the receiving groove 15 in the leading vertical frame 10 (described below), similar receiving grooves are provided in the other frames (described below). The plate-shaped member 3's end 3a is held in the receiving groove 15 via a gasket (glazing gasket) 4 into which the end 3a is fitted. Such a gasket 4 may be a glazing channel with a roughly C-shaped cross section or a glazing bead separated in the door thickness direction. The manner in which the plate-shaped member 3's end 3a is held in place by the peripheral frame 6 is not limited to this, and various other methods are possible.

1(a), the four-perimeter frame 6 includes an upper frame 7 that constitutes the upper end of the panel body 2 and a lower frame 8 that constitutes the lower end of the panel body 2. The four-perimeter frame 6 includes a trailing edge vertical frame 9 that constitutes the trailing edge end of the panel body 2, and a leading edge vertical frame 10 that constitutes the leading edge end of the panel body 2.
The upper frame 7 and the lower frame 8 are elongated in the door width direction. The upper frame 7 and the lower frame 8 are provided with receiving grooves that open in the directions facing each other and extend over their respective entire lengths.
The trailing edge vertical frame 9 and the leading edge vertical frame 10 are elongated in the door height direction. Receiving grooves 15 are provided in the trailing edge vertical frame 9 and the leading edge vertical frame 10 so as to open in the directions facing each other and extend over their respective entire lengths.

The dimensions of the upper frame 7, lower frame 8, trailing edge side vertical frame 9, and leading edge side vertical frame 10 in the door thickness direction are greater than the thickness of the plate-like member 3. The dimensions of the upper frame 7, lower frame 8, trailing edge side vertical frame 9, and leading edge side vertical frame 10 in the door thickness direction may be approximately the same as each other, or may be approximately the same as the thickness of a general door panel, for example, about 30 mm to 40 mm.
The dimensions of the upper frame 7 and the lower frame 8 along the door height direction and the dimensions of the trailing-side vertical frame 9 and the leading-side vertical frame 10 along the door width direction may be set to appropriate dimensions from the standpoint of strength, appearance, etc. The dimensions of the upper frame 7 and the lower frame 8 along the door height direction and the dimensions of the trailing-side vertical frame 9 and the leading-side vertical frame 10 along the door width direction may be approximately the same. In this embodiment, the dimensions of the upper frame 7 and the lower frame 8 along the door height direction are set larger than the dimensions of the trailing-side vertical frame 9 and the leading-side vertical frame 10 along the door width direction.

The dimension of the upper frame 7 and the lower frame 8 along the door height direction may be, for example, about 20 mm to 50 mm. The dimension of the upper frame 7 along the door height direction may include a cover attached to the upper frame 7 so as to cover the fixing portion of the runner.
The dimensions of the trailing edge vertical frame 9 and the leading edge vertical frame 10 along the door width direction may be approximately 10 mm to 30 mm.
The upper frame 7 and the lower frame 8 may be joined to the trailing edge side vertical frame 9 and the leading edge side vertical frame 10 by suitable fasteners such as screws. The upper frame 7 and the lower frame 8 may be joined to the trailing edge side vertical frame 9 and the leading edge side vertical frame 10 in a vertically or horizontally aligned manner.
The upper frame 7, lower frame 8, trailing edge vertical frame 9, and leading edge vertical frame 10 may be extrusion molded products made of an appropriate metal material. The surfaces of the upper frame 7, lower frame 8, trailing edge vertical frame 9, and leading edge vertical frame 10 may be made decorative by applying a decorative sheet or painting or other appropriate surface treatment.

1(b), the pull tab member 20 is provided so as to extend in the door height direction at a position spaced from the inner surface 11 facing the door trailing side of the door-end-side vertical frame 10 toward the door trailing side, and is provided with a handhold portion 21 that, together with the inner surface 11, defines both sides of the finger receiving recess 19 in the door width direction. With this configuration, the handhold portion 21 and the inner surface 11 of the door-end-side vertical frame 10 can form the finger receiving recess 19, and the dimension of the pull tab member 20 along the door width direction can be made smaller than in a configuration in which finger hook portions are provided on both sides in the door width direction. This allows the pull tab member 20 to have an appearance that is integrated with the door-end-side vertical frame 10.
The pull member 20 is provided so as to extend from both ends of the handle portion 21 in the door height direction toward the door edge, and is equipped with fixing portions 25, 25 that are fixed to the door edge-side vertical frame 10. With this configuration, the pull member 20 can be fixed to the door trailing end side of the door edge-side vertical frame 10 by the fixing portions 25, 25 that extend from the handle portion 21 toward the door edge, and can be attached even when the dimension along the door width direction of the door edge-side vertical frame 10 is small.

2(b), these fixing portions 25, 25 are abutted against the inner surface 11 of the door-end-side vertical frame 10 and fixed to the door-end-side vertical frame 10. With this configuration, the pull tab member 20 can be easily fixed to the door-end-side vertical frame 10, compared to a configuration in which an attachment portion is provided that fits into the receiving groove 15 that receives the end 3a of the plate-like member 3. In addition, the attachment portion that fits into the receiving groove 15 can prevent the gasket 4 that constitutes the retaining member that holds the end 3a of the plate-like member 3 from being severed.
1(c), 2(c), and 3(a) and 3(b), these fixing portions 25, 25 are provided with positioning protrusions 28, 28 that are inserted into positioning recesses 18, 18 formed in the side wall portions 16 that constitute the inner surface 11 of the door-end-side vertical frame 10. These fixing portions 25, 25 are provided with fastening portions 29, 29 for fasteners 5, 5 that are fastened from the outside in the door width direction of the door-end-side vertical frame 10. With this configuration, the fasteners 5, such as screws, can be fastened to the fastening portions 29 of the fixing portions 25 in a state where the positioning protrusions 28 of the fixing portions 25 are inserted into and aligned with the positioning recesses 18 of the door-end-side vertical frame 10, and deviation of the mounting position of the pull member 20 can be suppressed. In addition, each of the fixing portions 25, 25 at both ends of the handle member 20 in the door height direction can be firmly fixed to the door-end vertical frame 10 by fasteners 5, 5, and the handle member 20 can be easily replaced by removing the fasteners 5, 5.

The inner surface 11 of the door-leading side vertical frame 10 is formed as an inclined surface that slopes toward the door tail side as it moves from the outside in the door thickness direction toward the plate-shaped member 3. With this configuration, it is possible to reduce the dimension along the door width direction of the surface (visible surface) of the door-leading side vertical frame 10 facing outward in the door thickness direction while ensuring the dimension along the door width direction of the door-leading side vertical frame 10 itself, thereby giving a neat impression.
The mating surfaces 27, 27 of the fixing parts 25, 25 of the pull member 20 are inclined surfaces that follow the inner surface 11. With this configuration, the gaps between the fixing parts 25 and the inner surface 11 of the door-end vertical frame 10 can be made less noticeable than in a configuration in which the mating surfaces 27, 27 of the fixing parts 25, 25 are perpendicular to the surface of the plate-like member 3.

Specifically, as shown in Figure 2, the pull tab members 20 are provided on both sides in the door thickness direction. The inner surfaces 11, 11 on both sides of the leading-door vertical frame 10, along which the pull tab members 20, 20 are aligned, have inclined surfaces 12, 12 that slope from the outer edges of the door thickness direction toward the plate-shaped member 3, which is the center of the door thickness direction, toward the tail end. The inner surfaces 11, 11 on both sides in the door thickness direction, including the inclined surfaces 12, 12 on both sides, and the pull tab members 20 on both sides in the door thickness direction, are symmetrical with respect to the door thickness centerline in cross section. Therefore, the following description will focus on the inner surface 11 and pull tab member 20 on one side in the door thickness direction as an example. While not shown in detail, the inner surfaces of the upper frame 7, lower frame 8, and trailing-door vertical frame 9 described above also have substantially the same configuration as the inner surface 11 of the leading-door vertical frame 10. The trailing edge vertical frame 9 and the leading edge vertical frame 10 may have substantially the same configuration.

The inclined surface 12 defines the door-edge side of the finger receiving recess 19. This inclined surface 12 is provided over most of the door thickness direction from the outer edge of the inner surface 11 in the door thickness direction to the plate-shaped member 3. The inclined surface 12 has a concave curved surface shape that is approximately arc-shaped in cross section. The angle and radius of curvature of this inclined surface 12 with respect to the surface of the door-edge-side vertical frame 10 facing outward in the door thickness direction may be set as appropriate from the viewpoint of ease of handling, etc. As shown in FIGS. 1( b) and 1(c), the dimension of this inclined surface 12 along the door width direction when viewed in the door thickness direction is approximately the same as the dimension of the surface of the door-edge-side vertical frame 10 facing outward in the door thickness direction along the door width direction. In other words, the dimension of the surface of the door-edge-side vertical frame 10 facing outward in the door thickness direction along the door width direction is approximately half the dimension of the door-edge-side vertical frame 10 itself along the door width direction.
The inner surface end portion 13, which is the end portion of the inner surface 11 on the plate-like member 3 side, is formed in a substantially perpendicular plane with respect to the surface of the plate-like member 3. In other words, the inner surface 11 is not formed in an inclined plane over the entirety in the door thickness direction, but the inner surface end portion 13 is formed in a substantially perpendicular plane facing the door tail side. Instead of this configuration, the inner surface 11 may be formed in an inclined plane over the entirety in the door thickness direction.

1(c), positioning recesses 18, 18 are provided spaced apart in the door height direction on the inner surface 11 (inclined surface 12 in the illustrated example), into which positioning protrusions 28, 28 provided on the fixing parts 25, 25 on both sides in the door height direction of the pull member 20 are inserted. The illustrated example shows an example in which two positioning recesses 18, 18 are provided on the inner surface 11, into which one positioning protrusion 28, 28 provided on each of the fixing parts 25, 25 is inserted.
These positioning recesses 18, 18 are provided so that their axial direction is the door width direction. In the illustrated example, the positioning recesses 18, 18 are circular holes when viewed in the opening direction (door width direction). In the illustrated example, these positioning recesses 18, 18 are provided so as to penetrate the side wall portion 16, which is formed to extend from the outer portion in the door thickness direction toward the center in the door thickness direction substantially parallel to the inner surface 11, in the door width direction, but are not limited to this example. Both sides of the receiving groove 15 in the groove width direction are defined by the extending tip surfaces of the side wall portions 16, 16 on both sides in the door thickness direction that face each other.

The door-end vertical frame 10 has insertion holes 17, 17 through which fasteners 5, 5 are inserted, which are fastened to fastening portions 29, 29 provided on the fixing portions 25, 25 on both sides of the handle member 20 in the door height direction. The illustrated example shows two insertion holes 17, 17 extending through the door-end vertical frame 10 in the door width direction, through which fasteners 5, 5 are inserted, which are fastened to one fastening portion 29, 29 provided on each fixing portion 25, 25. These insertion holes 17, 17 are open on the surface of the door-end vertical frame 10 facing outward in the door width direction and on the inner surface 11 (inclined surface 12 in the illustrated example). The outer portions of these insertion holes 17, 17 in the door width direction have a larger diameter to accommodate the heads of the fasteners 5, 5, and the portions on the inner surface 11 have a smaller diameter to allow the shafts of the fasteners 5, 5 to be inserted. A cap-shaped member that covers the head of the fasteners 5 may also be attached to the outer side of the insertion holes 17 in the door width direction. In the example shown, the insertion holes 17 are positioned outside the positioning recesses 18 in the door height direction so that they correspond to the positioning protrusions 28 and fastening portions 29 of the pull member 20, respectively, but this is not a limited example.

2(b) and 3(a) and (b), the fixing portions 25, 25 of the pull member 20 have abutting surfaces 27, 27 that abut against the inner surface 11 and are inclined so that they become closer to the door edge as they extend from the center portion in the door thickness direction outward in the door thickness direction. These abutting surfaces 27, 27 are formed parallel to the inner surface 11 so as to abut against the inner surface 11 over substantially the entire surface. In other words, these abutting surfaces 27, 27 have a convex, curved inclined surface on the outside in the door thickness direction corresponding to the inclined surface 12, and a substantially vertical central portion in the door thickness direction that faces the door edge corresponding to the inner surface end portion 13.
The positioning protrusions 28 of these fixing portions 25 are provided so as to protrude from the mating surfaces 27 toward the door edge. In the illustrated example, the positioning protrusions 28 are substantially cylindrical in shape to correspond to the positioning recesses 18 described above.
The fastening portions 29, 29 of these fixing portions 25, 25 are recesses that are provided so as to open at the mating surfaces 27, 27. These fastening portions 29, 29 may be female threaded holes into which the male threaded portions of the fasteners 5, 5 are threaded, or may be pilot holes.

The surfaces of these fixing portions 25, 25 facing outward in the door height direction are substantially perpendicular to the surface of the plate-like member 3.
The surfaces (visible surfaces) of these fixing portions 25, 25 facing outward in the door thickness direction have a relatively small dimension along the door height direction. The illustrated example shows an example in which the dimension along the door height direction of the surfaces of these fixing portions 25, 25 facing outward in the door thickness direction is smaller than the dimension along the door width direction of the surfaces (visible surfaces) facing outward in the door thickness direction of the door front-side vertical frame 10. The illustrated example shows an example in which the surfaces of these fixing portions 25, 25 facing outward in the door thickness direction are positioned closer to the center in the door thickness direction than the surfaces facing outward in the door thickness direction of the door front-side vertical frame 10, but the present invention is not limited to this example.
The opposing surfaces of the fixing parts 25, 25 that define both sides of the finger receiving recess 19 in the door height direction are inclined surfaces 26, 26 that are inclined so as to approach each other from the outside in the door thickness direction toward the plate-shaped member 3. In the illustrated example, these inclined surfaces 26, 26 are substantially flat, but are not limited to this example.

The opposing surface 22 of the handhold portion 21 that defines the door trailing side of the finger receiving recess 19 is inclined so as to slope toward the door leading side from the outside in the door thickness direction toward the plate-shaped member 3. In other words, the inclined surface 12 of the door leading-side vertical frame 10 and the opposing surface 22 of the handhold portion 21 that faces it are inclined so as to slope toward the side that approaches from the outside in the door thickness direction toward the plate-shaped member 3. With this configuration, the finger receiving recess 19, which is defined on both sides in the door width direction by the inclined surface 12 of the door leading-side vertical frame 10 and the opposing surface 22 of the handhold portion 21, is widened when viewed in the door height direction (in cross section), making it easier to insert fingers. Furthermore, compared to a configuration in which these inclined surfaces 12 and the opposing surface 22 are perpendicular to the surface of the plate-shaped member 3, the feel can be improved.
Like the inclined surface 12, the opposing surface 22 is a concavely curved surface that is approximately arc-shaped in cross section. In the illustrated example, the opposing surface 22 and the inclined surface 12 are symmetrical with respect to a line equidistant from them in cross section. In other words, the opposing surface 22 and the inclined surface 12 have approximately the same dimensions along the door width direction when viewed in the door thickness direction. The inclined surface 12 and the opposing surface 22 are not limited to being concavely curved with an approximately arc-shaped cross section, but may also be a polygonal inclined surface, a substantially flat inclined surface, or any other type of inclined surface.

The surface (visible surface) of the handle portion 21 facing outward in the door thickness direction is parallel to the surface of the plate-shaped member 3, as is the surface of the door-end-side vertical frame 10 facing outward in the door thickness direction. The pull member 20 includes the surface of the handle portion 21 facing outward in the door thickness direction, and is attached so that this surface is not located further outward in the door thickness direction than the surface of the door-end-side vertical frame 10 facing outward in the door thickness direction, that is, so that it does not protrude outward in the door thickness direction. The illustrated example shows an example in which the pull member 20 is attached to the door-end-side vertical frame 10 so that the surface of the handle portion 21 facing outward in the door thickness direction is substantially flush with the surface of the door-end-side vertical frame 10 facing outward in the door thickness direction. The illustrated example also shows an example in which the dimension along the door width direction of the surface of the handle portion 21 facing outward in the door thickness direction and the dimension along the door width direction of the surface of the door-end-side vertical frame 10 facing outward in the door thickness direction are substantially the same.
The surface of the handle portion 21 facing the door trailing edge is substantially perpendicular to the surface of the plate-like member 3 .

As shown in Figures 1(b) and 2(a), the pull member 20 is provided with a bottom plate portion 23 that spans between the fixing portions 25, 25 on both sides in the door height direction and forms the bottom of the finger receiving recess 19. This configuration improves the strength of the pull member 20. The bottom plate portion 23 extends from the end of the handle portion 21 on the plate-shaped member 3 side toward the door edge. The bottom plate portion 23 is thin. The door edge side end of the bottom plate portion 23 abuts against the inner surface end portion 13 of the door edge-side vertical frame 10. The illustrated example shows an example in which the thickness dimension of the bottom plate portion 23 is approximately the same as the dimension along the door thickness direction of the inner surface end portion 13. The illustrated example also shows an example in which the dimension along the door width direction of the bottom plate portion 23 is approximately the same as the dimension along the door width direction of the surface of the handle portion 21 facing outward in the door thickness direction. In other words, as shown in Figure 1(b), the surfaces of the leading edge vertical frame 10 facing outward in the door thickness direction, the inclined surface 12, the bottom plate portion 23, the opposing surface 22, and the surfaces of the handle portion 21 facing outward in the door thickness direction all have approximately the same dimensions along the door width direction when viewed in the door thickness direction.

As shown in FIG. 1(a), this pull member 20 is attached to the door panel 1 at a midpoint in the door height direction so that it is at a height position that is easy to handle.
2(a) and 2(b), the pull member 20 is attached to the door-end vertical frame 10 so that a gap is formed between the back surface of the plate-like member 3, which is a flat surface parallel to the front surface of the plate-like member 3, and the front surface of the plate-like member 3. This gap may be approximately 0.5 mm to 1.0 mm. Alternatively, the pull member 20 may be attached with its back surface abutting against the front surface of the plate-like member 3.
The width dimension along the door width direction, depth dimension along the door thickness direction, and length dimension along the door height direction of the finger receiving recess 19 defined by this pull tab member 20 and the inclined surface 12 of the door-end vertical frame 10 may be set to appropriate dimensions so that a fingertip can be inserted and from the standpoint of ease of handling, etc. The depth dimension of the finger receiving recess 19 and the width dimension of the opening side portion of the finger receiving recess 19 may be, for example, 10 mm or more and 30 mm or less. The length dimension of the finger receiving recess 19 may be, for example, 50 mm or more and 300 mm or less.
The pull tab 20 may be a die-cast product made of a suitable metal material, or an injection-molded product made of a suitable synthetic resin material. The surface of the pull tab 20 may be made decorative by applying a decorative sheet or painting or other suitable surface treatment.

Next, a modified example of the door panel will be described with reference to FIGS.
The following mainly describes the differences from the above-mentioned example, and the same components are designated by the same reference numerals and their explanations are omitted or simplified. The explanations of the same effects as those of the above-mentioned example are also omitted or simplified.

FIG. 4(a) schematically shows an example of a pull member 20A included in an example of a door panel 1A according to a first modified example.
In this modified example, the pull tab member 20A has a different configuration from the above-described example in terms of the positioning protrusion 28A. This positioning protrusion 28A is provided so as to protrude in the door thickness direction from the abutting surface 27 of the fixing portion 25. This positioning protrusion 28A is provided so that its protruding tip surface is flush with the back surface of the pull tab member 20A. When such a positioning protrusion 28A is provided, a notched positioning recess 18 that opens toward the center in the door thickness direction may be provided in the side wall portion 16 of the door-end vertical frame 10, although this is not shown in the drawings.
4(b), the pull tab member 20A according to this modified example may be molded using a mold 30 having a first mold 31 and a second mold 35. In the illustrated example, the first mold 31, which is provided with an injection section 32, is provided with a recess 33 corresponding to the shape of the rear surface of the pull tab member 20A and a protrusion-forming recess 34 for forming the positioning protrusion 28A. Also, the illustrated example shows that the second mold 35 is provided with a protrusion 36 corresponding to the shape of the front surface of the pull tab member 20A.

FIG. 5(a) schematically shows an example of a door panel 1B according to a second modified example.
In this modified example, light blocking portions 14, 24 that block light transmission between the inner surface 11 of the door-end-side vertical frame 10A and the bottom plate portion 23 of the pull member 20B are provided at the abutment portion between them. With this configuration, light leakage at the abutment portion between the inner surface 11 of the door-end-side vertical frame 10A and the bottom plate portion 23 can be suppressed. In this modified example, a portion formed in a convex curved surface on the trailing-side edge of the tip of the side wall portion 16 of the door-end-side vertical frame 10A serves as the light blocking portion 14 on the door-end-side vertical frame 10A side. A protrusion that protrudes toward the door end side and constitutes the light blocking portion 24 is provided on the edge of the plate-shaped member 3 at the abutting side of the tip of the bottom plate portion 23 so as to follow the convex curved light blocking portion 14 of the side wall portion 16. The protrusions that make up this light blocking section 24 only need to be provided over at least the entire length of the bottom plate 23 in the door height direction, and may also be provided on the fixing sections 25, 25 on both sides in the door height direction. With this configuration, the protrusions that make up the light blocking section 24 of the bottom plate 23 can be fitted into the curved convex surface of the light blocking section 14 of the side wall 16, and this protrusion can suppress the transmission of light along the door thickness direction.

FIG. 5(b) schematically shows an example of a door panel 1C according to a third modified example.
In this modified example, as in the second modified example, light-shielding portions 14A, 24A are provided at the abutment portion between the inner surface 11 of the door-end-side vertical frame 10B and the bottom plate portion 23 of the pull member 20C. In this modified example, an example is shown in which the inner surface end portion 13 facing the door trailing side of the door-end-side vertical frame 10B is provided with a light-shielding portion 14A in the form of an inclined surface that slopes toward the plate-shaped member 3. An example is shown in which the tip surface on the abutting side of the bottom plate portion 23 is provided with a light-shielding portion 24A in the form of an inclined surface that slopes toward the outside in the door thickness direction so as to be approximately parallel to the light-shielding portion 14A of the door-end-side vertical frame 10B. With this configuration, even when the light-shielding portion 14A of the door-end-side vertical frame 10B and the light-shielding portion 24A of the bottom plate portion 23 abut against each other to form a gap, the abutment portion is inclined with respect to the door thickness direction, so that light transmission along the door thickness direction can be suppressed.

The light-shielding sections 14, 14A, 24, 24A provided on the door-end vertical frames 10A, 10B and the pull members 20B, 20C are not limited to the configurations described above. For example, one of the door-end vertical frames 10A, 10B and the pull members 20B, 20C may have a recess that opens in the door width direction, and the other may have a protrusion that is inserted into the recess. Alternatively, one of the door-end vertical frames 10A, 10B and the pull members 20B, 20C may have a soft part or the like that comes into contact with the other by elastic deformation or compressive deformation, or various other configurations may be used.
The different configurations described in the above examples may be appropriately modified, rearranged, or combined as needed.

In the above examples, the pull-tab members 20, 20A to 20C are provided with the bottom plate portion 23, but they may be configured without such a bottom plate portion 23. In other words, the bottom of the finger-receiving recess 19 of the pull-tab members 20, 20A to 20C may be formed of the plate-shaped member 3.
In each of the above examples, the inner surface 11 of the door-end vertical frame 10 and the opposing surface 22 of the handle portion 21 are shown as inclined surfaces, but one or both of these may be made approximately perpendicular to the surface of the plate-shaped member 3.
In the above examples, the fixing portion 25 is provided with the positioning protrusions 28, 28A and the fastening portion 29, but one or both of these may not be provided.
In each of the above examples, the handle members 20, 20A to 20C are attached to both sides of the door thickness direction of the door leading end, but the handle members 20, 20A to 20C may also be attached to only one side of the door thickness direction.
The above-described configurations of the components and parts of the door panels 1, 1A to 1C according to the above-described examples are merely examples, and various other modifications are possible.
