Description

[Technical field]

[0001] The present invention relates to a building fixture having a plurality of frame members. [Background technology]

[0002] Doors, windows, and other fixtures have multiple frame materials. Labels with certain information printed on them may be affixed to these frame materials in the assembly process, as it is necessary to check the order number, production sequence, and so on. However, there is a risk of human error such as labels falling off or being affixed incorrectly, and it is time-consuming to prepare and manage different labels for each frame material before affixing them. Furthermore, such labels, which have information about manufacturing and assembly printed on them, are not necessary for the completed product, and so may be peeled off before shipping, which places a burden on workers. On the other hand, it is possible to manage such information by attaching electronic tags such as RFID to each frame material, but electronic tags have the same inconveniences as labels and are expensive.

[0003] One possible technique for attaching predetermined information to a frame material is to use laser marking, as described in Patent Document 1. Laser marking eliminates the risk of labels falling off or being attached incorrectly, as occurs with labels. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2005-165659 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the information recorded in the laser marking described in Patent Document 1 is read as appropriate throughout the product's life cycle until it is discarded. When repairs, dismantling, reuse, or other treatments are performed, the information is added or updated, and is not used during the manufacturing and assembly processes. In addition, this laser marking needs to be provided in a position that can be read from the outside even after the frame material is assembled and the product is completed. Naturally, such information display is visible to users, which leads to a decrease in the appearance quality.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a fitting that eliminates human error in information management during the manufacturing and assembly processes, reduces the burden on workers, and does not deteriorate the appearance quality. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems and achieve the objectives, the fitting of the present invention is a fitting constructed by assembling a number of frame materials, and is characterized in that at least one of the frame materials is provided with a laser marking in which information relating to at least one of the manufacturing information and assembly information of the frame material is printed by a laser marker, and the laser marking is provided in a location that will be covered by other frame materials, other components, or the structure to which it is attached after assembly. Effect of the Invention

[0008] The fixtures of the present invention eliminate the risk of human errors such as mis-attaching or falling off, which occurs with labels, in information management during the manufacturing and assembly processes, reducing the burden on workers.In addition, since they are no longer necessary after the manufacturing and assembly processes, they can be attached in a location that is not visible, and do not degrade the appearance quality.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the fitting according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiment.

[0011] Fig. 1 is a schematic front view showing a fitting 10 according to an embodiment of the present invention. The fitting 10 comprises a frame 12 and a door panel 14, which is a frame structure, and the door panel 14 is supported by the frame 12 in a rotatable manner by a plurality of door links 38 interposed between the frame 12 and the door panel 14. The frame 12 comprises an upper frame 18, a lower frame 20, a right vertical frame 22, and a left vertical frame 24, which are framed on all four sides to form a vertically long rectangular shape. The fitting 10 is a casement window, but may also be a sliding door, door, etc.

[0012] In this application, the front direction refers to the indoor / outdoor direction of the fitting 10 (indicated by arrow Z in the figure; in FIG. 1, the direction perpendicular to the paper). The front surface refers to a surface extending along the front direction. The front direction refers to a direction perpendicular to the front direction, and in the case of a right vertical frame 22 that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction (the direction indicated by arrow X in the figure), and in the case of an upper frame 18 that is long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction (the direction indicated by arrow Y in the figure). The front surface refers to a surface extending along the front direction. The inside (inner circumference side) of a frame-shaped member refers to, for example, the inner frame part of the frame body 12. The outside (outer circumference side) of a frame-shaped member refers to, for example, the outer frame part on the frame body 12 side.

[0013] The upper frame 18, lower frame 20, right vertical frame 22, and left vertical frame 24 are extruded members made of metal such as aluminum alloy and resin, and each is configured to have a substantially uniform cross-sectional shape over its entire length along the longitudinal direction. The upper frame 18 and lower frame 20 are horizontal members, while the right vertical frame 22 and left vertical frame 24 are vertical members. The frame body 12 is attached to the framework 25 of a building. The framework 25 is made of, for example, wood or concrete.

[0014] The door panel 14 is constructed by attaching an upper frame 28, a lower frame 30, a right vertical frame 32, and a left vertical frame 34 to all four sides of a face material 26 such as a vertically long rectangular glass plate. A handle 36 is provided on the right vertical frame 32, which is located on the right side when viewed from the inside of the room. Door links 38 are provided on the upper frame 28 and the lower frame 30. In this embodiment, these door links 38 movably support the door panel 14 relative to the frame 12 so that it protrudes to the outside of the room. The fitting 10 has several other small parts in addition to the handle 36 and door link 38, but their explanation will be omitted.

[0015] The upper frame 28, lower frame 30, right vertical frame 32, and left vertical frame 34 that make up the door panel 14 are extruded members made of metal such as aluminum alloy and resin, and each is configured to have a substantially uniform cross-sectional shape along its entire length in the longitudinal direction. The upper frame 28 and lower frame 30 are horizontal members, while the right vertical frame 32 and left vertical frame 34 are vertical members. In this application, these frame members are considered a type of "frame member."

[0016] FIG. 2 is an exploded perspective view of the fitting 10. As shown in FIG. 2, the upper frame 18 is formed by combining a metal upper frame 18a and a resin upper frame 18b. The lower frame 20 is formed by combining a metal lower frame 20a and a resin lower frame 20b. The right vertical frame 22 is formed by combining a metal vertical frame 22a and a resin vertical frame 22b. The left vertical frame 24 is formed by combining a metal vertical frame 24a and a resin vertical frame 24b. The upper frame 28 is formed by combining a metal upper frame 28a and a resin upper frame 28b. The lower frame 30 is formed by combining a metal lower frame 30a and a resin lower frame 30b. The right vertical frame 32 is formed by combining a metal vertical frame 32a and a resin vertical frame 32b. The left vertical frame 34 is constructed by combining a metal vertical frame 34a and a resin vertical frame 34b.

[0017] In this way, the fitting 10 is composed of frame materials and stiles that are framed on all four sides, and is combined with metal extrusions and resin extrusions on each side, so that one fitting has a total of 16 extrusions. Also, each frame material needs to be distinguished from those for other products. For this reason, each frame material is marked with an identification laser marking Mn (n=1 to 10, typically referred to as laser marking M).

[0018] The laser marking M (see FIG. 9) contains at least one of the manufacturing information and assembly information of the frame material, and is printed on some or all of each frame material by a laser marker. A general-purpose laser marker can be used. The information contained in the laser marking M is not generally used after the fitting 10 is completed as a product. In addition, there is generally no need to add or update the information.

[0019] Marking on frame materials using a laser marker is performed by handling a robot. The robot, for example, is linked to a production management system, or is installed independently for each manufacturing line of frame materials, and can correctly identify the frame material to be marked, preventing incorrect information from being printed. This type of laser marking M does not have the risk of falling off, as with labels, and also eliminates the trouble of preparing and managing different ones for each frame material. It is recommended that the laser marking M be printed in white on dark-colored frame materials and in black on light-colored frame materials.

[0020] Next, the printing position of the laser marking M will be described. 3 is an exploded perspective view of the upper frame 18. The metal upper frame 18a has a fin piece 18aa that protrudes upward. A laser marking M1 is applied to the exterior facing surface at the end of the fin piece 18aa. The metal upper frame 18a is attached to a structure 25, and the exterior facing surface of the fin piece 18aa is covered by the structure 25. Therefore, since the laser marking M1 is covered by the structure 25, it will not be visible after the fitting 10 is completed as a product. The metal upper frame 18a has a wall portion 18ab that forms a visible surface on the inner periphery side.

[0021] The laser marking M1 is composed of a two-dimensional code M1a and character information M1b. The two-dimensional code M1a and character information M1b are arranged close to each other. Hereinafter, for the laser marking M, the suffix "a" indicates the two-dimensional code and "b" indicates the character information.

[0022] The resin upper frame 18b has a laser marking M2 on the outer peripheral side visible surface at the end of the outer peripheral side wall portion 18ba. The resin upper frame 18b is attached to the inner peripheral side of the metal upper frame 18a, and the outer peripheral side visible surface of the wall portion 18ba is covered by the wall portion 18ab. Therefore, the laser marking M2 is not visible.

[0023] 4 is an exploded perspective view of the lower frame 20. The metal lower frame 20a has a fin piece 20aa that protrudes downward. A laser marking M3 is applied to the exterior facing surface at the end of the fin piece 20aa. The metal lower frame 20a is attached to the frame 25, and the exterior facing surface of the fin piece 20aa is covered by the frame 25. Therefore, the laser marking M3 is not visible. The metal lower frame 20a has a pair of fin pieces 20ab that protrude toward the inner periphery.

[0024] The resin lower frame 20b is a substantially plate-shaped frame material attached to the inner periphery of the pair of fin pieces 20ab. A laser marking M4 is applied to the outer periphery of the end of the resin lower frame 20b. Since the resin lower frame 20b is attached to the pair of fin pieces 20ab, the laser marking M4 is not visible.

[0025] 5 is an exploded perspective view of the right vertical frame 22. The metal vertical frame 22a has a fin piece 22aa that protrudes toward the outer periphery. A laser marking M5 is applied to the exterior facing surface at the end of the fin piece 22aa. The metal vertical frame 22a is attached to a frame 25, and the exterior facing surface of the fin piece 22aa is covered by the frame 25. Therefore, the laser marking M5 is not visible. The metal vertical frame 22a has a wall portion 22ab that protrudes in the forward direction.

[0026] The resin vertical frame 22b is a frame material attached to the inner periphery side of the wall portion 22ab. At the end of the wall portion 22ba that forms the visible surface of the resin vertical frame 22b, a laser marking M6 is applied to the visible surface on the outer periphery side. Since the resin vertical frame 22b is attached to the inner periphery side of the wall portion 22ab, the laser marking M6 is not visible. The left vertical frame 24 also has the laser markings M5 and M6, similar to the right vertical frame 22.

[0027] 6 is an exploded perspective view of the upper frame 28. The metal upper frame 28a has a wall portion 28aa that forms a visible surface and a fin piece 28ab that protrudes in the forward direction from the wall portion 28aa. A laser marking M7 is applied to the exterior visible surface at the end of the wall portion 28aa.

[0028] FIG. 7 is a partially enlarged exploded perspective view of the upper frame 28 and the left vertical frame 34. The end of the metal upper frame 28a is configured to be fitted into the fitting portion 34c of the left vertical frame 34. The fitting portion 34c is a portion in which both sides in the projection direction, that is, the inside and outside of the room, are covered by the wall portion 34aa of the metal vertical frame 34a and the resin vertical frame 34b. The laser marking M7 is covered by the wall portion 34aa in the fitting portion 34c and cannot be seen. The two-dimensional code M7a and the character information M7b are arranged vertically so that the laser marking M7 does not protrude from the fitting portion 34c. In this example, the upper frame 28, which is a horizontal member, is fitted into the fitting portion 34c of the left vertical frame 34, which is a vertical member, but conversely, the laser marking M may be attached to the end of the vertical member, and the end may be fitted into the fitting portion of the horizontal member.

[0029] Returning to FIG. 6, the plastic upper frame 28b has a wall portion 28ba forming a visible surface and an engagement portion 28bb formed on the wall portion 28ba. A laser marking M8 is provided on the visible surface on the exterior side at the end of the wall portion 28ba. The plastic upper frame 28b is fixed to the metal upper frame 28a by the engagement portion 28bb engaging with the edge of the fin piece 28ab. The laser marking M8 is provided on the surface of the metal upper frame 28a facing the wall portion 28aa, and is not visible. The lower frame 30 is also provided with the laser markings M7 and M8, similar to the upper frame 28.

[0030] 8 is an exploded perspective view of the right vertical frame 32. The metal vertical frame 32a has a wall 32aa forming a visible surface, a hollow rectangular column 32ab protruding from the wall 32aa to the interior side, and two engagement portions 32ac provided along the longitudinal direction of the rectangular column 32ab. A laser marking M9 is applied to the inner peripheral visible surface at the lower end of the rectangular column 32ba. Since the end of the metal vertical frame 32a is attached to the fitting portion of the lower frame 30, the laser marking M9 is covered by the lower frame 30 and cannot be seen.

[0031] The resin vertical frame 32b is a substantially plate-shaped frame material, and has a laser marking M10 on the lower end on the exterior facing surface. The resin vertical frame 32b has two engagement parts 32bb extending in the longitudinal direction. The resin vertical frame 32b is attached to the metal vertical frame 32a by engaging the engagement parts 32bb with the engagement parts 32ac. The laser marking M10 is made on the surface of the metal vertical frame 32a facing the rectangular column part 32ab, and is not visible. The left vertical frame 34 is also made with the laser markings M9 and M10, just like the right vertical frame 32.

[0032] FIG. 9 is a schematic diagram showing laser marking M. As described above, laser marking M indicates information related to manufacturing and assembly, and is referred to in the manufacturing process (including the conveying process, the inspection process, etc.) and the assembly process. Laser marking M basically consists of two-dimensional code Ma and character information Mb, but only one of them may be used depending on the conditions. The information indicated by the two-dimensional code Ma and the information indicated by the character information Mb may overlap in part or in whole. Laser marking M is not visible after the frame materials are assembled, but is provided in a position that is easy to mark with a laser marker and easy to read by a scanner and visually before assembly. The information of laser marking M will be further explained below.

[0033] The two-dimensional code Ma is, for example, a QR code (registered trademark). The two-dimensional code Ma is read by a scanner in the manufacturing process and assembly process. The scanner is operated by a worker, but may also be operated by an automated machine such as a robot. The two-dimensional code Ma is information related to parts, packaging, coincidence / non-coincidence between production process information and the actual product, information related to production results, etc.

[0034] The character information Mb is made up of letters or symbols such as numbers or letters of the alphabet, and indicates a code based on a predetermined rule. The character information Mb includes an order number, production sequence information, part type information, model number, drawing number information, packaging delivery date information, color information, dimension information, number of sets information, etc.

[0035] The order number is an allocation number for a production order or an individual identification number. The production sequence information indicates the production sequence on the manufacturing assembly line. The part type information is identification information for the position on the four sides of the frame. For example, "L" indicates left, "R" indicates right, "U" indicates top, and "D" indicates bottom. The model number and drawing number information is the part model number and drawing number information and is used during processing inspection. The packaging delivery date information is instruction information that is processed with priority given to the delivery date when a reorder occurs or the packaging delivery date of an order. The color information indicates the color of the frame material and is used to distinguish between similar colors. The dimension information indicates the length of each part of the frame material and is used during inspection. The number of sets information is used to sort the number of sets of the same order or frame materials in order of yield in order of production.

[0036] However, these pieces of information are related to manufacturing and assembly, and are not used basically after each frame material is assembled into the fitting 10 and completed. Therefore, there is no need to read them from the outside after the product is completed, and they can be placed in an invisible position as described above, so that the appearance quality does not deteriorate. Unlike labels, the laser marking M is not peeled off, and since it is placed in an invisible position, there is no need to erase it, which reduces the burden on the worker. Therefore, such laser marking M eliminates human error in the information management of the manufacturing and assembly process, reduces the burden on the worker, and does not deteriorate the appearance quality. The laser marking M is placed on the end of each long frame material, making it easy for the worker to find the laser marking M.

[0037] In the above-mentioned fitting 10, the laser marking M is applied to each of the frame materials and stiles 16 that make up the frame body 12 and the door panel 14, but it is not necessary to apply the laser marking M to all of them, and depending on the conditions, a suitable effect can be obtained by applying the laser marking M to at least one of the frame materials. Also, parts other than the frame materials and stiles, such as the handle 36 and door link 38, may also have the laser marking M applied in a position that is not visible after completion. When the amount of information required is small, the two-dimensional code Ma may be replaced with a one-dimensional code.

[0038] FIG. 10 is an exploded perspective view of a frame 40 and a surface material (another component) 42 according to a modified example. The frame 40 has a wall portion 40a forming a front surface, and fin pieces 40b, 40c protruding inward from the wall portion 40a. The fin pieces 40b, 40c are provided on both sides of the front surface of the wall portion 40a, that is, on the inside and outside of the room. The surface material 42 is fitted into an opening 40d formed between the fin pieces 40b, 40c. The surface material 42 is, for example, a double-glazed glass, and a resin spacer (not shown) is provided between the wall portion 40a. A laser marking M is printed on the inner front surface of the wall portion 40a (i.e., the surface facing the end face of the surface material 42). In this case, the frame 40 may be either a horizontal member or a vertical member.

[0039] The laser marking M thus applied to the frame 40 is not visible from either the inside or outside of the room because it is blocked by the fin pieces 40b, 40c. In addition, since the facing material 42 is fitted into the opening 40d and the wall portion 40a is somewhat recessed, the laser marking M is substantially not visible from the inner periphery.

[0040] In this way, the frame material that covers the laser marking M in the fitting 10 so that it is not visible may be a frame material, a frame material, or a building block, and may be covered with the facing material 42. The laser marking M may also be applied to the facing material 42 in a position that will not be visible after completion. Also, if the fitting 10 is a non-fireproof type, there is no need to provide a fireproofing material or a fire-resistant material on the wall portion 40a, and this is suitable for applying the laser marking M.

[0041] The fixture of the present invention is constructed by assembling a number of frame materials, and is characterized in that at least one of the frame materials is provided with a laser marking in which at least one of the manufacturing information and assembly information of the frame material is printed by a laser marker, and the laser marking is provided in a location that will be covered by other frame materials, other components, or the structure to which it is attached after assembly. Such fittings eliminate the risk of human error, such as mis-attaching or falling off, which occurs with labels, in information management during the manufacturing and assembly processes, reducing the burden on workers. Furthermore, since they are no longer needed after the manufacturing and assembly processes, they can be attached in a way that is not visible, and do not degrade the appearance quality.

[0042] The building fixture of the present invention comprises a frame body formed on all four sides by the frame material, and a face material arranged on the inner side of the frame body, and is characterized in that the laser marking is provided on the surface of the frame body facing the end face of the face material. If the fittings are of a non-fire rated type, such areas can be laser marked.

[0043] The building fixture of the present invention is characterized in that the frame materials form a frame body with a framework on all four sides, and the laser marking is affixed to one end of each vertical and horizontal member of the frame body, and the other end is fitted into an insertion portion which is covered on both sides in the prospective direction by walls, and the laser marking is covered by the walls which form the insertion portion. In this way, the laser marking applied to the end portion of the frame material becomes invisible by fitting it into the fitting portion of another frame material that constitutes the frame body.

[0044] The present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit and scope of the present invention. [Explanation of symbols]
