TECHNICAL FIELD OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention relates to fittings, and can be used, for example, as entrances to buildings, doors at open doors, and the like.
[0002]
[Background Art]
Conventionally, door panels such as doors are composed of a frame composed of an upper frame, a lower frame, and left and right vertical frames, and indoor and outdoor materials that are attached to the indoor and outdoor surfaces of the frame, respectively. In addition, there has been known a door panel in which both the inside and outside surfaces of the door panel have a substantially flat double-sided flush structure. In addition, such a door panel may be provided with a middle window for daylighting. As such a middle window, a planar member such as ground glass is housed and arranged in an opening penetrating the door panel, and the planar member is disposed. A structure in which the inner frame from the indoor side and the outer frame from the outdoor side sandwich the frame is adopted.
[0003]
[Problems to be solved by the invention]
However, in such a structure of the middle window, it is necessary to secure a sufficient swallowing dimension for securely holding the planar member in each of the inner frame and the outer frame. There is a problem that the dimensions are increased. For this reason, it has been difficult to satisfy the demand for making the frame look thinner to improve the appearance or the inner appearance.
[0004]
Moreover, the inner frame and the outer frame are provided with a margin for covering the periphery of the opening of the interior facing material and the exterior facing material, and the margin allows each margin to be slightly hidden. In other words, a good fit is achieved. Therefore, this margin is also a factor, albeit slightly, to increase the size of each frame.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a fitting that can reduce the found size of a member arranged around a center window and can also easily accommodate a face material around the center window.
[0006]
[Means for Solving the Problems]
The fitting of the present invention is a fitting comprising a panel body having an indoor surface material and an outdoor surface material attached to an indoor surface and an outdoor surface, respectively, and a middle window provided at an opening penetrating the panel body. The middle window includes a planar member disposed in the opening, and a frame disposed on the indoor side and / or the outdoor side in the opening to form a swallow portion of the planar member. At the same time, a covering portion is provided on the indoor facing material and / or the outdoor facing material on the side where the picture frame is provided, and a covering portion is provided to cover a vertically visible portion of the picture frame. It is characterized by being covered with an end of an attachment covering a surface facing the part.
[0007]
In such an embodiment of the present invention, the frame, which has conventionally been a main factor for increasing the found size, is covered with the covering portion of the indoor facing material or the outdoor facing material, so that the frame itself becomes invisible. In the present invention, the attachment that covers the frame is visible, but the only visible part of the attachment is the end that slightly covers the peripheral edge of the cover of the face material. Only the part corresponding to the generation. Therefore, around the middle window, the attachment having a small find size becomes visible, and a good appearance or introspection can be obtained. Also, by covering the peripheral edge of the face material with the end of such an attachment, the accommodation of the face material is maintained as well as in the past.
[0008]
In the fitting of the present invention, it is preferable that the attachment is provided with a mounting portion for a sealing material that is in close contact with the planar member.
Although it is possible to attach the sealing material to the frame and make it adhere to the sheet member, in the present invention in which the frame is covered with the attachment, when the sealing material is attached to the frame, water droplets and the like enter between the frame and the attachment. Stagnation, and the drainage may deteriorate. On the other hand, if the seal is attached to the attachment, the picture frame will be placed in a space that is almost completely sealed by the attachment, the seal, and the planar member, and water drops will flow down on the attachment. Therefore, the drainage property is good.
[0009]
In the fitting of the present invention, it is preferable that the attachment is attached to the frame by mechanical attachment means.
In such a configuration, it is necessary to select the material of the attachment in consideration of fire prevention and to set the size of the end part, that is, the size of the allowance, etc., to ensure that the standard as a fitting for fire doors in houses is met. And is particularly useful as a fitting having fire protection performance.
[0010]
In this case, it is preferable that the attachment means is constituted by a locking portion and a locked portion provided on the attachment and the frame.
As the mechanical attachment means, screwing means using screws and screw holes, bolts and nuts and the like are also conceivable, but by using the mechanical attachment means by the locking part and the locked part, the attachment The structure of the frame and the frame are simplified, and their manufacture is facilitated.
[0011]
Furthermore, it is preferable that the locking portion of the attachment and the locked portion of the frame are provided in a snap-type manner so as to be freely detachable.
In such a configuration, the attachment is disengaged with a single touch to the frame, so that the assembling work is performed easily and quickly, so that the workability is improved, and the maintenance is performed when the attachment is removed. Is also easy to maintain.
[0012]
In the fitting of the present invention, the frame is provided with an inclined surface that approaches the center of the opening as the distance from the surface material increases, and the attachment includes an abutting surface that is in contact with the inclined surface. It is preferable that the surface of the planar member on the frame side is supported by an attachment.
In such a configuration, the attachment (the contact surface) slides along the inclined surface portion of the frame due to the reaction force received from the surface material. For example, when the members forming the frame exist on four sides, the members are mutually connected. Since it comes close to the center of the opening, it adheres well, and the gap between the members is closed, so that the appearance and the sealing performance are remarkably improved.
[0013]

The outer frame 33 and the inner frame 34 swallow and hold the four peripheral edges of the glass surface material 31. A swallowing portion 36 is formed.
[0019]
The external frame 33 has a structure in which an upper frame member 331, a lower frame member 332, and left and right vertical frame members 333, each of which is made of a metal extruded shape such as aluminum or steel, are framed. The member 333 is a long member that is substantially continuous in the vertical direction of the panel body 20, and an upper frame member 331 and a lower frame member 332 are arranged between these members and screwed. That is, the vertical frame material 333 in the present embodiment is continuous over a plurality of middle windows 30 provided along the vertical direction, and is commonly used by the middle windows 30. The external frame 33 is screwed in advance to a frame that forms the panel body 20.
[0020]
In each of the frame members 331 to 333 of the external frame 33, the vertical outdoor surface 33A which conventionally forms a visible part from the outside is flush with the outdoor surface 23A of the heat insulating core 23 in the present embodiment. At the same time, it is covered with a cover 22A provided on the side of the opening 20A of the outdoor facing material 22, and is actually invisible in appearance. The cover 22A is fixed to the outdoor surface 33A by, for example, an adhesive.
[0021]
On the other hand, the inner frame 34 is provided independently for each middle window 30 and joins the upper frame 341, the lower frame 342, and the left and right vertical frame 343 made of the same extruded metal by 45 °. It is a structure that is framed around four times. The inner frame 34 is framed in advance by frame materials 341 to 343. After the glass surface material 31 is arranged on the indoor side of the outer frame 33 from the indoor side, it is further fitted from the indoor side. At this time, the fitted inner frame 34 is mechanically attached to the outer frame 33 integrated with the panel main body 20 by the attachment members 37 and 38 made of resin.
[0022]
In FIG. 3, the mounting member 37 arranged on the side surface of the middle window 30 includes two mounting pieces 37A and 37B that are slidable in the vertical direction with respect to each other. And the mounting piece 37B is fitted to the claw of the outer frame 33. On the other hand, as shown in FIG. 2, the mounting members 38 arranged on the upper and lower portions of the middle window 30 are made of one member, and are fitted to the claw portions of the frames 33, 34. That is, both the attachment members 37 and 38 are attached to the frames 33 and 34 by a snap method. Also, in the middle window 30 having a small width and height, only one mounting member 37, 38 is provided at each of the upper, lower, left and right sides of the middle window 30, but in the middle window 30 which is vertically long and has a large height, A plurality, for example, three, of the mounting members 37 are arranged according to the height dimension. Further, the mounting member 38 on the lower side of the middle window 30 also serves as a block for mounting the glass surface material 31.
[0023]
In the inner frame 34 joined in this manner, the end 344 forming the outer peripheral portion of each of the frame members 341 to 343 is fixed to the edge of the interior facing member 21 on the opening 20A side by a predetermined margin (the direction of finding). To 3 mm or more, and slightly covers the edge of the indoor facing material 21 from the indoor side. Thereby, the fitting of the edge of the interior facing material 21 becomes good, and the flame does not easily flow around the heat insulating core material 23, so that the structure meets the fire prevention standard. However, this structure is the same in the related art.
[0024]
Each of the attachments 35 is vertically arranged on four sides in the outer frame 33, and includes a main body 351 that covers the inner side surface 33 </ b> B of the outer frame 33 (each frame material 331 to 333), and an outdoor part of the main body 351. A bent portion 352 which is provided at an end portion and which has a predetermined margin (3 mm or more in the finding direction) at an edge of the outdoor facing material 22 on the side of the opening 20A; and a frame which is provided on the indoor side of the main body portion 351 Locking portions 353 that are locked to the locked portions 335 of the members 331 to 333. Then, the locking portion 353 and the locked portion 335 constitute the mounting means according to the present invention, and each of the independently provided attachments 35 is mechanically snapped to each of the frame members 331 to 333 by mechanical means. It is designed to be detachably attached.
[0025]
The bent portion 352 of the attachment 35, like the end portion 344 of the inner frame 34, hangs on the edge of the outdoor surface material 22 on the side of the opening 20 </ b> A at a predetermined margin (3 mm or more in the finding direction). The edge of the outdoor facing material 22 is slightly covered from the indoor side. Thereby, the fitting of the edge of the interior facing material 21 becomes good, and the flame does not easily flow around the heat insulating core material 23, so that the structure meets the fire prevention standard. In other words, one of the most characteristic features of the present embodiment is that the outer frame 33 covers the edge of the outdoor facing material 22 in the related art, whereas the outer frame 33 covers the outer surface material 22 with the attachment 35.
[0026]
Further, in the present embodiment, on the outer side of the bent portion 352, a decorative edge 40 continuous around four turns is arranged so as to cover the bent portion 352, and is attached to the outdoor facing material 22 with an adhesive or the like. . Although the find size of the decorative frame 40 is slightly larger than the find size of the bent portion 352, it is much smaller than the find size of the external frame 33 which cannot be hidden and seen or the inner frame 34 which is viewed inside. Therefore, in the door panel 10 of the present embodiment, the members around the middle window 30 look thinner than before in the external view from the outside, and the members around the middle window 30 in the inside view from the inside in the same manner as in the related art. It will look thicker, and will look different between internal and external viewing. However, in the present invention, the decorative edge 40 is not an essential component and can be omitted. When the decorative edge 40 is omitted, the bent portion 352 of the attachment 35 is viewed from the outside. However, since the bent portion 352 has a small finding size as well as the bent portion 352, the members around the middle window 30 are also thin. Will be visible.
[0027]
A lip groove (mounting portion) 355 for attaching a sealing material 354 is provided on the indoor side of the locking portion 353 of the attachment 35, and a continuous sealing material 354 over each of the four independent attachments 35 is formed on a glass surface. It is in close contact with the outdoor surface of the material 31. The outside of the glass panel 31 is supported by the attachment 35 via the sealing member 354. The same sealing material 354 provided on the inner frame 34 is in close contact with the indoor surface of the glass face material 31.
[0028]
Further, the locking portion 353 is provided with a contact surface 356 that comes into contact with the inclined surface portion 336 of the frame members 331 to 333. At this time, the inclined surface portion 336 is inclined so as to approach the center side of the opening 20A as the distance from the glass surface material 31 toward the external frame 33 side increases, and the attachment 35 is attached to the supporting glass surface material 31. Is brought to the center side of the opening 20A along the inclination of the inclined surface portion 336 by the reaction force from. As a result, the attachments 35 arranged vertically are in close contact with each other, and there is no gap at the boundary between the attachments 35, and the sealing performance is improved.
[0029]
In addition, a gap 337 is formed between the main body 351 of the attachment 35 and the inner surface 33B of each of the frame members 331 to 333, and a vertical winning structure in which the upper and lower attachments 35 are arranged between the left and right attachments 35. In the present embodiment, it is possible to set the dimensional tolerance of the upper and lower attachments 35 to the plus side particularly by the gap 337. This is because the gap 337 can absorb a portion longer than the standard size. Therefore, the upper and lower attachments 35 can be manufactured to be longer than the standard length, and the dimensional tolerance at this time is large, so that the manufacture is facilitated.
[0030]
According to this embodiment, the following effects can be obtained.
(1) That is, in the door panel 10 of the entrance door 1, when the peripheral portion of the middle window 30 is viewed from the outside, the outdoor surface 33A of the external frame 33 having a large finding dimension has been exposed in the related art. Since the outdoor surface 33A of the external frame 33 is covered with the cover 22A of the outdoor surface material 22, the external frame 33 itself can be made invisible. Instead, in the door panel 10, the attachment 35 that covers the outer frame 33 or the makeup edge 40 is provided when the makeup edge 40 is provided. However, the attachment 35 and the makeup edge 40 swallow the glass surface material 31. Since the function of holding at the position is unnecessary, the only visible portion is the bent portion 352 at the end where the attachment size is much smaller if the attachment 35 is used, and , Only the exterior surface, where the found dimensions are likewise small. Therefore, only a member having a small found size can be seen at the peripheral portion of the middle window 30, and a good appearance can be obtained. In addition, since the periphery of the outdoor facing material 22 is covered by the bent portion 352 of the attachment, the accommodation of the outdoor facing material 22 can be maintained as well as in the related art.
[0031]
(2) In the door panel 10 of the present embodiment, when viewed from the outside, the attachment 35 and the decorative edge 40 having a small size are visible, while when viewed from the inside, the attachment 35 and the decorative edge 40 are found in the same manner as in the related art. Since the large inner frame 34 can be seen, the appearance impression on the door panel 10 can be made different between when viewed from the outside and when viewed from the inside, and the design can be improved.
[0032]
(3) The attachment 35 is provided with a lip groove 355, and the lip groove 355 is provided with a sealing material 354 that is in close contact with the glass surface material 31, so that the attachment 35, the sealing material 354, and the glass surface material 31 The outer frame 33 can be arranged in a space that is almost completely sealed, and there is no fear that water droplets will enter and stay between the outer frame 33 and the attachment 35, thereby improving drainage.
[0033]
(4) Each of the frame members 331 to 333 constituting the external frame 33 is a hollow extruded shape member and has a complicated shape such as having a claw portion to which the mounting members 37 and 38 are mounted. Since the 354 is attached to the attachment 35 side, it is not necessary to provide a lip groove 355 or the like for attaching the seal material 354 on each of the frame materials 331 to 333, and it is possible to avoid further complication of these shapes, The cost of the extrusion die can be reduced, and the yield of the frame members 331 to 333 can be improved.
[0034]
(5) In particular, since the vertical frame material 333 is continuous over the upper and lower middle windows 30 and has a vertical winning structure with respect to the upper frame material 331 and the lower frame material 332, each of the frame materials 331 to 331 is formed. When the lip groove 355 is provided in the 333, it is necessary to construct a structure for communicating the lip grooves 355 of the respective frame members 331 to 333, which is troublesome. On the other hand, since the attachment 35 is an independent member for each of the four windows around each middle window 30, the lip grooves 355 of each attachment 35 can be easily communicated with each other, and the assembling work can be facilitated.
[0035]
(6) The attachment 35 that covers the outdoor facing material 22 with the bent portion 352 is mechanically attached to the locked portion 335 of each of the frame materials 331 to 333 by the locking portion 353. Even when the attachment 35 is used, the entrance door 1 can reliably meet the standard as a door for a house fire door, and is particularly useful as a door having fire protection performance.
[0036]
(7) At this time, since the locking portion 353 of the attachment 35 and the locked portion 335 of each frame material 331 to 333 only need to have a structure that can be hooked to each other, they can be realized in a simple shape and extruded. Can be easily manufactured. Furthermore, since screwing means such as screws and bolts are not used, there is no need to worry about exposing these heads, improving the appearance and design, and eliminating the need to use a tightening tool. The attachment 35 can be easily attached to the middle window 30 having a small width or height that cannot be attached.
[0037]
(8) The locking portion 353 of the attachment 35 and the locked portion 335 of each of the frame members 331 to 333 are snap-engaged and detachably provided, so that the attachment 35 can be engaged with the external frame 33 with one touch. The attachment work can be easily and quickly performed to improve the workability, and the maintenance performance when the attachment 35 is removed for maintenance can be improved.
[0038]
(9) By making the contact surface 356 of the attachment 35 contact the inclined surface portion 336 provided on each of the frame materials 331 to 333, the attachment 35 is moved along the inclined surface portion 336 by the reaction force received from the glass surface material 31. Can be slid. For this reason, each frame material 331-333 comes to come into close contact with the center side of the opening 20A, and closes the gap between each frame material 331-333 to significantly improve the appearance and sealability. Can be.
[0039]
(10) Since a gap 337 is formed between the main body 351 of the attachment 35 and the inner surface 33B of each of the frame members 331 to 333, the dimensional tolerance of the upper and lower attachments 35 is particularly limited by the gap 337. It can be set larger on the plus side, and the upper and lower attachments 35 can be made longer than the standard length. Therefore, since the dimensional tolerance is large, the labor and the burden required for manufacturing the upper and lower attachments 35 can be reduced, and the manufacturing can be easily performed.
[0040]
Note that the present invention is not limited to the above embodiment.
For example, in the above-described embodiment, each frame material 331 to 333 is provided with the inclined surface portion 336, and each attachment 35 is provided with the contact surface 356. However, as shown in FIG. Also, the present invention includes a case where there is no abutment surface 356 that abuts on the contact surface. With such a configuration, the above-mentioned effect (9) cannot be obtained, but other effects can be obtained similarly.
[0041]
FIG. 5 shows an example in which a lip groove 355 for attaching the sealing material 354 is provided not on the attachment 35 but on each of the frame materials 331 to 333. Such a configuration is also included in the present invention. However, in such a configuration, the locking portion 353 of each of the frame materials 331 to 333 cannot be provided large, and a good locking state may not be obtained. Fixing to each frame material 331-333 is also considered.
[0042]
In the embodiment, the gap 337 is formed between the attachment 35 and each of the frame members 331 to 333. However, without providing such a gap 337, the attachment 35 and each of the frame members 331 to 333 are substantially The contact may be made in the whole area, and whether or not to provide the gap 337 may be arbitrarily determined in the implementation.
[0043]
In the above embodiment, the attachment 35 that covers the frame members 331 to 333 of the external frame 33 has been described. However, such a configuration may be applied to the indoor side. That is, the interior side surface of each frame material 341 to 343 of the inner frame 34 is covered with the interior surface material 21, and each frame material 341 to 343 is covered with another attachment 35, so that when the door panel 10 is internally viewed, The found size of the member existing around the window 30 may be reduced. Further, in a case where the glass face material 31 can be arranged after the outer frame 33 and the inner frame 34 are attached, the attachment 35 may be used both indoors and outdoors, when viewed from the outside and when viewed from the inside. In either case, the found size can be made to look small.
[0044]
Further, the present invention includes a case where the attachment is attached to the frame by a mechanical attachment means, and a case where the attachment is attached by a non-mechanical attachment means such as an adhesive, welding, or brazing. However, in such a configuration, there is a possibility that the standard of the fire door in the house may not be satisfied. Therefore, it is desirable to attach the door by mechanical attachment means as in the embodiment. In particular, among them, the attaching means including the locking portion and the locked portion is more preferable as described in the above embodiment.
[0045]
In the embodiment, the glass surface material 31 has been described as the surface member according to the present invention. However, the surface member is not limited thereto, and may be any material such as synthetic resin, wood, stone, and metal. A planar member can be applied.
