Description

  The present invention relates to a daylighting panel provided with a daylighting unit, which is a panel used for an open door, a sliding door, a wall surface or the like used in a building.

  2. Description of the Related Art Conventionally, in daylighting type open doors, sliding doors, wall panels, etc. used in buildings, as shown in FIG. The core material S is attached, and the frame G in the vertical direction and the horizontal direction is attached to the core material S at the periphery of the opening of the daylighting panel 11 from both sides of the front and back surfaces of the daylighting panel 11. A daylighting panel 11 having a structure in which the translucent member 3 is sandwiched from both sides has been used.

  In the daylighting panel 11 having this structure, the work for attaching the frame G to the core S around the opening is complicated and inferior in workability, and the frame protrudes from the daylighting panel surface. However, when it comes to sliding doors, the frames are easily touched during opening and closing operations, and are difficult to use.

  Therefore, a window frame structure that uses a frame joined from the front and back without using a frame, and fits and holds the end of the glass plate directly in a groove provided on the inner peripheral surface of the frame has been conventionally used. It is disclosed, and the conventional problems such as protrusion of the frame are solved. However, it is difficult to maintain sufficient strength because the frames are simply joined from the front and back, and the ends of the translucent member are fitted and sandwiched between the frames and the end of the translucent member. Such a complicated work is required, and it is difficult from the viewpoint of workability, which is not only inferior in strength and durability but also disadvantageous in cost.

  Therefore, this point is solved, the conventional frame is not required, the face part and the edge part are integrally formed so as to be a flat surface, and it has an excellent appearance with no bulge, and is durable in strength. In order to realize an excellent daylighting door, an opening is provided in the daylighting door, a core material is disposed on the inner peripheral surface of the opening, and an edge that forms the inner peripheral surface of the opening is formed on the inner peripheral edge of the core door. Provided so that the opposing surfaces come into contact with each other from the front and back sides, and are integrally formed so that the outer surface of the surface portion and the edge portion are in one plane, and the inner peripheral surface of the edge portion formed by contacting the opposing surface of the edge portion There is a description of a daylighting door having a configuration in which a notch portion for forming a fitting groove substantially equal to the thickness of the translucent member is provided and the outer peripheral edge of the translucent member is fitted into the fitting groove. (For example, refer to Patent Document 1).

Utility Model Registration No. 2526552 (Page 1-4, Figure 1-3)

  By the way, in the above-mentioned prior art, in the frame type, the work when attaching the frame to the core around the opening is complicated and inferior in workability, and the frame protrudes greatly from the surface of the lighting panel. However, when used as a sliding door, the frames are easily touched during opening and closing operations, and are difficult to use.

  Further, in a structure in which a frame is used without using a frame, and an end portion of a translucent member such as a glass plate is fitted and sandwiched directly into a groove provided on the peripheral surface of the frame, the projection of the frame Although the conventional problems are solved, it is difficult to maintain sufficient strength because the frames are simply joined from the front and back, and the ends of the translucent member and the joints between the frames are attached to the inner circumferential surface of the frame. Due to the structure in which the groove is fitted and clamped, the work is complicated, the workability is inferior, the strength durability is inferior, and the cost is disadvantageous.

  Further, in the prior art disclosed in the above-mentioned utility model registration No. 2526552, the outer surface of the surface portion and the edge portion are integrally formed so that the outer surfaces of the edge portions are in one plane, and the opposing surfaces of the edge portions are brought into contact with each other. A configuration in which a notch for forming a fitting groove having a thickness substantially equal to the thickness of the translucent member is provided on the inner peripheral surface of the formed edge, and the outer peripheral edge of the translucent member is fitted into the fitting groove. Therefore, the structure is complicated, the assembling work is complicated, the workability is inferior, and the cost is disadvantageous.

  Further, if the width dimension and depth dimension of the fitting groove are processed extremely accurately, packing for preventing the light-transmitting member from rattling is not necessary, but in order to maintain the processing accuracy therefor. It requires extremely high technical skills and is expensive. In addition, if the processing is performed with normal processing accuracy, the packing is always necessary.

  Moreover, in any of the above prior arts, when the room is reformed, only the translucent member is replaced for a user who wants to change the color pattern or the like of the translucent member of the daylighting door and renew the design. It was impossible, and the lighting door itself had to be replaced. In addition, there are similar problems for a user who wants to renew the light-transmitting member when it is damaged or old.

  The present invention has been made in view of the above-described circumstances, and the object of the present invention is that a frame is unnecessary, so that the structure is simple, it can be sufficiently processed with normal processing accuracy, and the conventional daylighting panel must be used. No need for packing, excellent assembly workability, no projections such as picture frames from the surface of the lighting panel, and very few translucent members protruding, so it can be used for sliding doors and is durable In addition, the object of the present invention is to provide a daylighting panel that can be replaced with a new translucent member very easily and at a low cost for reform and maintenance.

  The daylighting panel according to claim 1, which has been made to solve the above-mentioned problems, is a daylighting panel in which a translucent member is provided on a panel body having a predetermined width, height, and thickness. An opening that penetrates in the thickness direction is provided in the main body, and the translucent member is inserted into the opening, and the thickness of the translucent member is substantially equal to or slightly larger than the thickness of the daylighting panel. The front and back surfaces of the translucent member protrude from the front and back surfaces of the daylighting panel by a predetermined dimension to form a protruding portion, and a chamfered portion having a predetermined size is formed at the peripheral corner of the protruding portion. It is characterized by having.

  According to the present invention having such a configuration, there is no need to provide a frame for attaching the translucent member and a fitting groove for inserting the end edge of the translucent member on the inner peripheral surface of the opening. In addition, since the base core material on the inner peripheral surface of the opening is not visible from the outside without applying makeup to the inner peripheral surface of the opening, it is excellent in workability and cost as much as makeup is unnecessary, and is also excellent in aesthetics. It will be a thing.

  That is, since the translucent member has a thickness substantially equal to or slightly larger than the thickness of the daylighting panel (usually about 20 mm to 40 mm), the opening is made of a transparent material having a large refractive index. When the optical member is inserted, the incident light from the outside is totally reflected, so that the base core material on the inner peripheral surface of the opening portion can be externally applied without applying makeup to the inner peripheral surface of the opening portion of the daylighting panel. Disappears. This means that the translucent member does not need to protrude greatly from the front and back surfaces of the daylighting panel, and if it is substantially equal to or slightly protrudes from the front and back surfaces of the daylighting panel, as described above, the daylighting panel Even if no makeup is applied to the inner peripheral surface of the opening, the base core material on the inner peripheral surface of the opening is not visible from the outside, which is suitable for design.

  Moreover, since the structure is not complicated, it is excellent in assembling workability. Further, since the translucent member is merely inserted into the opening of the daylighting panel, the translucent member can be renewed very easily for reform and maintenance. It can be replaced.

  Further, the protrusion of the translucent member from the surface of the daylighting panel may be extremely small, and the chamfering process is performed on the peripheral corner portion of the protruding portion, and a chamfered portion of a predetermined size is formed. The design is even better. In addition, since the chamfered portion is provided, there is little risk of injury caused by hooking a finger or the like by the protruding portion, which is preferable from the viewpoint of safety.

  Moreover, since the protrusion of the translucent member from the daylighting panel surface may be extremely small, an inexpensive daylighting panel that can be used for a sliding door and has excellent strength durability can be obtained.

  A daylighting panel according to a second aspect of the present invention is the daylighting panel according to the first aspect, wherein a soft resin layer is provided between the outer peripheral surface in the thickness direction of the translucent member and the inner peripheral surface of the opening. It is characterized by being formed.

  According to the present invention having such a configuration, since the soft resin layer functions to prevent the light transmissive member from rattling, no packing or the like is required to prevent the light transmissive member from rattling. Since the structure is not complicated, it is excellent in assembling workability and inexpensive.

  According to a third aspect of the present invention, in the daylighting panel of the first aspect, a small recess is formed at a predetermined position on the outer peripheral surface of the surface of the translucent member in the thickness direction. A soft small protrusion is provided at a predetermined position on the inner peripheral surface of the opening of the daylighting panel at a corresponding position.

  According to the present invention having such a configuration, the light-transmitting member can be attached and fixed easily and firmly by fitting the small concave portion and the small protrusion to each other. The protrusion can be easily removed from the small recess, and the translucent member can be removed very easily.

Therefore, the translucent member can be newly replaced if necessary, and an inexpensive daylighting panel can be obtained.

  According to a fourth aspect of the present invention, in the daylighting panel of the first aspect, a fitting groove having a predetermined length is formed along the longitudinal direction of the outer peripheral surface in the thickness direction of the translucent member. A soft fitting body having a predetermined length is provided along the longitudinal direction on the inner peripheral surface of the opening of the daylighting panel at a position corresponding to the fitting groove.

  According to the present invention having such a configuration, by fitting the fitting groove and the fitting body to each other, the translucent member can be attached and fixed very easily and securely, and when removing, The fitting body can be easily removed from the fitting groove, and the translucent member can be removed very easily. It is suitable for workability, mounting accuracy, and strength when removing and installing the translucent member during reform and maintenance.

  According to the invention of claim 1 of the present invention, the panel body having a predetermined width, height, and thickness is provided with an opening penetrating in the thickness direction, and the translucent member is fitted into the opening, The thickness of the translucent member is substantially equal to or slightly larger than the thickness of the daylighting panel, and the front and back surfaces of the translucent member project from the front and back surfaces of the daylighting panel by a predetermined dimension, Since a chamfered portion of a predetermined size is formed at the peripheral corner of the projecting portion, a frame for attaching the translucent member and an edge of the translucent member are inserted. Therefore, there is no need to provide a fitting groove on the inner peripheral surface of the opening.

  In addition, the base material on the inner peripheral surface of the opening cannot be seen from the outside without applying makeup to the inner peripheral surface of the opening. It will be a thing. That is, since the translucent member has a thickness substantially equal to or slightly larger than the thickness of the daylighting panel (usually about 20 mm to 40 mm), the opening is made of a transparent material having a large refractive index. When the optical member is inserted, the incident light from the outside is totally reflected, so that the base core material on the inner peripheral surface of the opening portion can be externally applied without applying makeup to the inner peripheral surface of the opening portion of the daylighting panel. Disappears. This means that it is not necessary that the translucent member protrudes greatly from the front and back surfaces of the daylighting panel. If the front and back surfaces of the daylighting panel are substantially equal or only slightly protruded, as described above, the daylighting panel is used. Even if no makeup is applied to the inner peripheral surface of the opening, the base core material on the inner peripheral surface of the opening is not visible from the outside, which is suitable for design.

  Moreover, since the structure is not complicated and the translucent member is merely inserted into the opening of the daylighting panel, the assembly workability is excellent.

  Further, the projection of the translucent member from the surface of the daylighting panel may be extremely small, and the chamfering process is performed on the peripheral corner portion of the projecting portion to form a chamfered portion of a predetermined size. Sexuality will be even better. In addition, since the chamfered portion is provided, there is little risk of injury caused by hooking a finger or the like by the protruding portion, which is preferable from the viewpoint of safety.

  Moreover, since the protrusion of the translucent member from the daylighting panel surface may be extremely small, an inexpensive daylighting panel that can be used for a sliding door and has excellent strength durability can be obtained.

  According to the second aspect of the present invention, since the soft resin layer is formed between the outer peripheral surface in the thickness direction of the translucent member and the inner peripheral surface of the opening, the soft resin layer is Since it works to prevent rattling of the translucent member, conventional packing or the like for preventing rattling of the translucent member is unnecessary, and therefore, the structure is not complicated and the assembly workability is excellent and inexpensive. It becomes.

  According to invention of Claim 3 of this invention, a small recessed part is formed in the predetermined position of the outer peripheral surface of the surface of the thickness direction of a translucent member, and the inner periphery of the opening part of the lighting panel of the position corresponding to this small recessed part Since a soft small protrusion is provided at a predetermined position on the surface, it is possible to easily and securely mount and fix the translucent member by fitting the small recess and the small protrusion together. The small protrusion can be easily removed from the small recess, and the translucent member can be removed very easily. At the time of reform and maintenance, the translucent member can be attached and detached very easily. Therefore, the translucent member can be newly replaced if necessary, and an inexpensive daylighting panel can be obtained.

  According to the invention of claim 4 of the present invention, the fitting groove having a predetermined length is formed along the longitudinal direction of the outer peripheral surface in the thickness direction of the translucent member, and the lighting at the position corresponding to the fitting groove is performed. Since a soft fitting body having a predetermined length along the longitudinal direction is provided on the inner peripheral surface of the opening of the panel, it is extremely easy to fit the fitting groove and the fitting body together, The translucent member can be securely attached and fixed, and when removing, the fitting body can be easily detached from the fitting groove, and the translucent member can be removed very easily. It is suitable for workability, mounting accuracy, and strength when removing and installing the translucent member during reform and maintenance.

  An example of an embodiment of the present invention will be described in detail with reference to the drawings. 1A and 1B show a daylighting panel of the present invention, in which FIG. 1A is a front view thereof, FIG. 1B is a cross-sectional view taken along line A-A, and FIG. FIG. 2 is a perspective view of the daylighting panel according to the present invention, and is an explanatory view showing a state where a translucent member is inserted into the opening. FIG. 3 is an enlarged cross-sectional view showing the main part of the first embodiment of the daylighting panel of the present invention. 4A and 4B show a second embodiment of the daylighting panel of the present invention, in which FIG. 4A is an enlarged cross-sectional view of an essential part thereof, and FIG. 4B is an explanatory view showing a state where a translucent member is inserted into an opening. FIG. 5 shows a third embodiment of the daylighting panel of the present invention, in which (A) is a perspective view of a translucent member provided with a fitting groove, and (B) is a perspective view of the fitting body.

  1 and 2, the daylighting panel 1 of the present invention includes a panel body 2 and a translucent member 3. The panel main body 2 has predetermined width dimensions, height dimensions, and thickness dimensions, and an opening K for fitting the translucent member 3 into a predetermined position of the panel main body 2 is provided. The opening K penetrates from the front surface of the panel body 2 to the back surface. In this example, one opening K having an elongated shape in the vertical direction is provided in the approximate front center of the panel body 2. However, it is not limited to this. Two or more may be sufficient, and a horizontal direction, the diagonal direction, etc. may be sufficient. The position, shape, etc. of the opening K may be other than those shown in this example. It can be determined as appropriate in consideration of the finished design of the daylighting panel 1 and the like.

  An example of the cross-sectional structure of the daylighting panel 1 of the present invention will be described. The panel body 2 is provided with a surface decorative board H with the core material S sandwiched between the front and back surfaces of the panel body 2 and has a so-called flash structure. In this example, an opening K is provided as a through hole substantially at the center, and the translucent member 3 is fitted into the opening K. In this example, the flash structure is described, but a solid structure using a solid wood material may be used.

  The translucent member 3 has a thickness substantially equal to or slightly larger than that of the panel body 2 and is substantially flush with the surface of the surface decorative board H provided on the front and back surfaces of the panel body 2 or slightly. Projecting from the front and back surfaces of the panel main body 2 by the size, a protruding portion T is formed. Further, a chamfering process having a predetermined size is applied to the peripheral corner portion of the protruding portion T, and a chamfered portion M is formed.

  The surface decorative board H of the panel body 2 of the daylighting panel 1 of the present invention includes, for example, a plywood, a medium specific gravity fiber board, and other wooden base materials, an olefin resin decorative sheet, a vinyl chloride resin decorative sheet, and a cosmetic. A decorative sheet in which a decorative sheet such as paper, a veneer or a veneer of a natural wood is pasted, and the surface is painted, a decorative sheet in which the wooden base material is painted, or a calcium or pulp cement In addition to decorative plates that have been surface-coated by attaching the above-mentioned various decorative sheets, natural veneer plates, veneers, etc., to inorganic base materials such as plates, metal decorative plates such as galvanized steel plates and coated steel plates, etc. Can be exemplified as a preferable one.

  Moreover, as the translucent member 3, an acrylic resin molded body, a polycarbonate resin molded body, a laminated glass body bonded with a transparent or translucent plate glass, a tempered glass body, a netted glass body, a template glass body In addition to the above, other transparent or translucent resin molded bodies are used. In addition to being colorless, it may be colored with emphasis on design.

  In addition, the protrusion dimension of the protrusion T of the translucent member 3 is preferably about 0.3 to 1.0 mm. If it is smaller than about 0.3 mm, the chamfering process is difficult to perform, and it is difficult to form the chamfered portion M. Moreover, when the protrusion dimension of the protrusion is larger than about 1.0 mm, it protrudes too much from the front and back surfaces of the daylighting panel 1 and is difficult to use as a sliding door. Further, the chamfered shape of the chamfered portion M may be either the C surface or the R surface. The chamfering angle of the chamfered portion M in the case of the C surface is just about 120 to 150 degrees from the surface of the decorative plate H of the panel body 2 as a design.

  Further, at the position of the opening K, a core material having a width of about 40 to 60 mm wider than the width dimension of the opening K may be placed in advance at the time of manufacturing the flash panel. By doing so, when the opening K having a predetermined width is processed at the center of the core material, the core material having a width of about 20 mm to 30 mm remains on both the left and right sides of the opening K. Further, as a machine and jig for processing the opening K, an NC router, a handle rotor, and the like are suitable. Moreover, when fixing the translucent member 3 to an opening part with an adhesive agent, an adhesive agent is apply | coated to the surface of the core material S exposed to the internal peripheral surface of the opening part K, and the translucent member 3 is opened. Push it carefully into K. Wipe away any excess adhesive with a solvent. As the adhesive, a resin adhesive such as a silicon-based mastic type or asphalt type is suitable as an inelastic type. Moreover, as the elastic adhesive having softness after curing, resin adhesives such as acrylic, SBR, butyl rubber, silicon, and urethane are suitable.

The detail of the procedure of the manufacturing method of the lighting panel 1 of this example is described below.
1. Two surface decorative boards H having a predetermined width, length and thickness are prepared.
2. Materials such as LVL (parallel plywood), normal plywood, particle board, solid Batesga, raw lauan, etc. are prepared as the core material constituting the periphery of the daylighting panel.
3. In this example, since the opening K is approximately the center in the width direction and has one place in the longitudinal direction, for example, when the width of the opening K is 50 mm, the opening K is located at the planned processing position of the opening K of the panel body 2. A core material S (90 to 110 mm wide core, or 90 to 110 mm wide by combining two to three) may be installed at a predetermined position when the panel body 2 is manufactured. Keep it.
4). As the translucent member 3, in this example, one colorless and transparent acrylic resin molding that matches the size and shape of the opening K is prepared. At this time, the thickness of the acrylic resin molding was prepared by 1.0 mm larger than the thickness of the daylighting panel in this example, and the dimension of the protruding portion T was set to 0.5 mm on the front and back surfaces. Further, the chamfered portion M was chamfered with a C surface, and the chamfering process was performed using a grinder with an inclination angle of 135 degrees based on the surface decorative board H.
5. An NC router, a handle rotor, or the like was used to process the opening K as a through hole into a predetermined size and shape.
6). In this example, asphalt adhesive was applied to the surface of the core part of the inner peripheral surface of the opening K, and the acrylic resin molded body was carefully and slowly fitted into the opening K. The overflowing adhesive was wiped off with a solvent.
7). The lighting panel 1 was completed by gently curing at room temperature for about 48 hours.

  In FIG. 3, sectional drawing of 1st embodiment of the lighting panel 1 of this invention is shown. In this example, a soft resin layer is formed between the outer peripheral surface in the thickness direction of the translucent member and the inner peripheral surface of the opening. After the adhesive was cured, a soft resin layer J was formed, and conventional packing or the like became unnecessary. Moreover, as the elastic adhesive having softness after curing, resin adhesives such as acrylic, SBR, butyl rubber, silicon, and urethane are suitable. In this example, an acrylic resin adhesive was used as an elastic adhesive that forms a soft layer after curing on the surface of the core S exposed on the inner peripheral surface of the opening K.

  In FIG. 4, sectional drawing of 2nd embodiment of the lighting panel 1 of this invention is shown. As an attaching method of the translucent member 3, an example of a small recess P provided in the translucent member 3 and a small projection Q fitted to the small recess P is shown. In this example, the small recessed part P is formed in the approximate center of the translucent member 3 in the thickness direction. However, it may not be substantially in the center in the thickness direction, and may be slightly shifted in the thickness direction from the center. The small recesses P are, for example, conical small holes opened on the surface, and at least two on each of the left and right sides of the translucent member 3, preferably on the left and right sides in the longitudinal direction. There are 6 places on the surface, 3 places on the middle and 3 places on the bottom. The shape of the small recess P is not limited to a conical shape, but a hemisphere, a quadrangular pyramid, a triangular pyramid, a truncated cone, a quadrangular frustum, a triangular frustum, or a cross-sectional shape of a circle, an ellipse, a square, a triangle, or other shapes. The cylindrical body etc. can be illustrated. Of course, other than these may be used.

  On the other hand, the small protrusion Q is a resin molded body having a base portion Q1 and a protrusion portion Q2 protruding from the base portion Q1. As the material of the resin molding, a molding such as a soft vinyl resin, a soft olefin resin, a soft acrylic resin, or a soft urethane resin is preferable. The shape of the protrusion Q2 is a shape commensurate with the shape of the small recess P. In this example, it has a conical shape with a sharp tip. In addition to the conical shape, the shape of the projections Q2 of the small recesses P and the small projections Q is not limited to a hemisphere, a quadrangular pyramid, a triangular pyramid, a truncated cone, a quadrangular pyramid, a triangular pyramid, and a cross-sectional shape of An elliptical shape, a square shape, a triangular shape, or other shapes of cylindrical bodies can be exemplified. Of course, other than these may be used. Of course, the position of the small recess P and the position of the small protrusion Q are aligned.

  In this example, the base Q1 of the small protrusion Q is embedded in the core material S of the opening K, and only the protrusion Q2 protrudes from the inner peripheral surface of the opening. When the translucent member 3 is carefully inserted toward the opening K, the chamfered portion M on the back surface side formed on the translucent member comes into contact with the soft protrusion Q2, and the chamfered portion M has an inclination angle. Since the component force of the pushing force works in the direction perpendicular to the chamfered inclined surface, the soft projecting portion Q2 is pressed moderately, the projecting portion Q2 is pressed and pushed into the base portion Q1, The inner peripheral surface of the opening is a substantially flat surface. When the translucent member 3 is continuously pushed in, the small recess P provided in the middle of the thickness direction of the translucent member 3 reaches the projection Q2 of the small projection Q, and the projection Q2 enters the small recess P. Mating. In this way, the translucent member 3 is inserted into the opening K of the panel body 2 and is fixed and held. On the other hand, when removing the translucent member 3 at the time of reform or renewal at the time of maintenance, it can be easily removed by the reverse action described above.

  FIG. 5 shows a third embodiment of the daylighting panel of the present invention. Another embodiment of how to attach the translucent member 3 to the daylighting panel 1 of the present invention will be described in detail. A fitting groove KM is provided along the longitudinal direction of the translucent member 3 in the vicinity of the approximate center in the thickness direction of the translucent member 3 instead of the small recess P in FIG. Examples of the cross-sectional shape of the fitting groove KM include a semicircle, a square meter, a trigonometer, and a trapezoid other than the V shape shown in this example. Of course, other than these may be used. On the other hand, a fitting body KG fitted to the fitting groove KM is provided on the core material S on the inner peripheral surface of the opening K. The fitting body KG includes a base portion KJ and a protruding portion TJ protruding from the base portion KJ. The base portion KJ is embedded in the core material S and is formed from the inner peripheral surface of the opening K. Only the protrusion TJ protrudes.

  Suitable materials for the base portion KJ and the protruding portion TJ are molded products such as a soft vinyl resin, a soft olefin resin, a soft acrylic resin, and a soft urethane resin. The mechanism for fitting the translucent member 3 into the opening K is the same as in the case of the small recess P and the small protrusion Q described above.
