Description

[Technical Field]

[0001] The present invention relates to a structure for wiring a frame-side cable to a frame material. [Background technology]

[0002] In fittings that have electrical components such as an electric lock in a door body, electricity is supplied to the electrical equipment in the door body via a frame-side cable arranged in the frame body. That is, an insertion hole is formed in the vertical frame that constitutes the frame body, and the frame-side cable connected to a power source in the room is passed through the insertion hole in the vertical frame to the hanging point, and is connected to the internal door cable of the door body via a relay part called an electric fitting, thereby supplying electricity to the electric lock (see, for example, Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2022-29689 Summary of the Invention [Problem to be solved by the invention]

[0004] The frame materials for building fixtures are generally made of metals such as aluminum alloys. Therefore, simply passing a frame-side cable through a through-hole formed in the vertical frame raises the risk of the frame-side cable coming into contact with the edge of the through-hole, potentially damaging the cable. This problem can be solved by providing a protective component, such as a grommet, in the through-hole. However, this increases the number of parts required, leading to increased manufacturing costs and more complicated assembly work.

[0005] In view of the above situation, the present invention aims to provide a wiring structure for a frame material that can prevent damage to frame-side cables without increasing manufacturing costs or complicating assembly work. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the wiring structure of a frame material according to the present invention has a metal frame portion molded from metal and a resin frame portion molded from resin, and is a wiring structure of a frame material in which a frame side cable is arranged in a frame material formed by arranging the metal frame portion and the resin frame portion side by side, wherein the metal frame portion has an outer insertion portion through which the frame side cable can pass in a resin frame opposing wall portion facing the resin frame portion, and the resin frame portion has an inner insertion portion through which the frame side cable can be inserted in a metal frame opposing wall portion facing the metal frame portion, and the inner insertion portion has a portion that faces the outer insertion portion and is on the inner side of the outer insertion portion. [Effects of the Invention]

[0007] According to the present invention, the opening edge of the inner insertion portion formed in the resin frame portion is located more inward than the opening edge of the outer insertion portion formed in the metal frame portion, so it is possible to prevent damage caused by the frame side cable coming into contact with the opening edge of the outer insertion portion without the need for additional parts such as grommets, and there is no risk of increased manufacturing costs or complicated assembly work.

DETAILED DESCRIPTION OF THE INVENTION

[0009] A preferred embodiment of the wiring structure of a frame material according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "prospect direction" and "visibility direction" will be used below. The prospect direction is the direction along the depth of the fixture, as indicated by arrow A in the drawings. A surface along the prospect direction will sometimes be referred to as a "prospect surface." The prospect direction is the direction perpendicular to the prospect direction in the case of an element that extends horizontally, such as a top frame. In the case of an element that extends vertically, such as a vertical frame, the horizontal direction perpendicular to the prospect direction is called the "prospect direction." A surface along the prospect direction will sometimes be called a "prospect surface."

[0010] 1 to 3 show a fixture to which a wiring structure for a frame material according to an embodiment of the present invention is applied. The fixture illustrated here is a door used at the entrance of a building such as a detached house, and in particular, illustrates a renovation entrance door that is installed while leaving the existing frame body 1. That is, in this entrance door, a new upper frame 11, a lower frame 12, and left and right vertical (frame material) frames 13, 14 for renovation are installed on the inner periphery of the existing upper frame 1a, lower frame 1b, and left and right vertical frames (existing frame material) 1c attached to the skeleton B, thereby forming a frame body 10 for supporting a new door panel (door body) 15 so that it can be opened and closed. The new upper frame 11 and left and right vertical frames 13, 14 each have an exterior metal frame section 11A, 13A, 14A made of metal such as aluminum alloy, and an interior resin frame section 11B, 13B, 14B made of resin. The metal frame sections 11A, 13A, 14A and the resin frame sections 11B, 13B, 14B are arranged side by side in the forward direction. The metal frame sections 11A, 13A, 14A and the resin frame sections 11B, 13B, 14B are each extruded shapes with a substantially uniform cross-sectional shape along their entire length. The new lower frame 12, on the other hand, has an interior frame section 12A and an exterior frame section 12B made of metal such as aluminum alloy, and a bridge member 12C made of insulating material. The bridge member 12C connects the interior frame section 12A and the exterior frame section 12B. Although not shown in the figure, the door panel 15 is a so-called flush panel, which is constructed by arranging surface materials on frameworks that are framed all around. In this embodiment, the vertical frame located on the left side when viewed from the inside of the room (hereinafter referred to as the left vertical frame 13 for distinction) serves as the hanging point, and hinge 16 is provided between the door panel 15 and the vertical frame 14 located on the right side as the door edge, and an electric lock (electrical component) 30 is provided between the door panel 15 and the vertical frame 14.

[0011] 4 to 6 show the left vertical frame portion of the fixture. Below, with reference to these figures, we will mainly describe in detail the detailed configuration of the existing vertical frame 1c, the new left vertical frame 13, and the wiring structure for supplying electricity to the electric lock 30, and also explain the characteristics of the present invention. For convenience, the components of the existing frame body 1 attached to the skeleton B will be referred to as "existing," such as "existing vertical frame 1c," and the components of the newly installed frame body 10 will be referred to as "new," such as "new left vertical frame 13," to distinguish between the two.

[0012] As shown in Figure 4, the existing vertical frame 1c includes an existing vertical main body 1ca, an existing vertical doorstop wall 1cb, an existing vertical outer peripheral hollow 1cc, and an existing vertical mounting wall 1cd. The existing vertical main body 1ca is a flat plate extending approximately vertically along the projection direction. The existing vertical doorstop wall 1cb protrudes inward from the interior side of the projection surface of the existing vertical main body 1ca. The portion of the existing vertical doorstop wall 1cb facing the exterior is provided with an existing vertical seal material mounting portion 1ce that protrudes toward the exterior. The existing vertical outer peripheral hollow 1cc protrudes toward the exterior from the exterior side of the projection surface of the existing vertical main body 1ca and has a cylindrical cross section. The existing vertical mounting wall 1cd extends from the interior side corner of the exterior side of the existing vertical outer peripheral hollow 1cc toward the exterior. This existing vertical frame 1c is attached to the structure B with the existing vertical outer peripheral hollow section 1cc protruding outside the room by abutting the visible surface facing the room of the existing vertical outer peripheral hollow section 1cc and the existing vertical mounting wall section 1cd against the surface facing outside the room of the structure B.

[0013] The metal frame portion 13A of the new left vertical frame 13, which is the target of repairing the existing vertical frame 1c, has a new vertical outer frame body 13a with a roughly rectangular cross-section and a cylindrical shape. A new vertical locking piece 13b extending toward the room is provided at the corner located on the indoor side of the outer periphery of the new vertical outer frame body 13a. A new vertical outer hook portion 13c and a new vertical outer seal material attachment portion 13d are provided at the corner located on the indoor side of the inner periphery of the new vertical outer frame body 13a. The new vertical outer hook portion 13c extends toward the room and then bends toward the outer periphery. The new vertical outer seal material attachment portion 13d is used to attach the vertical outer seal member C1 and protrudes toward the inner periphery. The plastic frame portion 13B of the new left vertical frame 13 has a new vertical inner frame body 13e with a roughly rectangular cross-section and a cylindrical shape. The dimensions of the new vertical inner frame body 13e along the projection direction are smaller than those of the new vertical outer frame body 13a, and the dimensions along the front view direction are approximately the same as those of the new vertical outer frame body 13a. A new vertical door stop wall 13f is provided at the corner on the inner periphery of the new vertical inner frame body 13e that is located on the interior side of the room. The new vertical door stop wall 13f protrudes toward the interior from the new vertical inner frame body 13e and has a new vertical seal material attachment portion 13g for attaching the seal member C2 to the portion facing the outside of the room. A partition wall 13h is provided on the portion of the new vertical inner frame body 13e that is closer to the interior side of the room. The partition wall 13h extends in the front view direction so as to divide the cylindrical interior of the new vertical inner frame body 13e into two sections in the projection direction. At the corners of the new vertical inner frame body 13e located on the exterior side of the room, new vertical engaging claws 13i are provided on the outer periphery, and new vertical inner hooks 13j are provided on the inner periphery. The new vertical engaging claws 13i protrude toward the outer periphery and are provided to correspond to the new vertical locking pieces 13b of the metal frame part 13A. The new vertical inner hooks 13j extend toward the exterior and then bend toward the inner periphery, and are provided to correspond to the new vertical outer hooks 13c of the metal frame part 13A.

[0014] The metal frame portion 13A and resin frame portion 13B of the new left vertical frame 13 are interconnected by engaging the new vertical outer hook portion 13c with the new vertical inner hook portion 13j and by engaging the new vertical locking piece 13b with the new vertical locking claw portion 13i. They are then integrated by threading a frame connecting screw S1 into the new vertical outer frame body 13a via the new vertical inner frame body 13e. The dimensions of the new left vertical frame 13, which integrates the metal frame portion 13A and resin frame portion 13B, along the projected direction are larger than the dimensions of the portion of the existing vertical body 1ca that is located outside the existing vertical sealant mounting portion 1ce. Furthermore, vertical frame fixing brackets 13C are attached at multiple locations along the length of the outer periphery of the new left vertical frame 13. The vertical frame fixing bracket 13C is formed from a metal such as steel or aluminum alloy and has a vertical fixing piece 13Ca and a vertical mounting piece 13Cb. The vertical fixing piece 13Ca is a flat plate extending from the metal frame 13A to the resin frame 13B, and is attached to the new left vertical frame 13 by screwing a screw S2 into each of the vertical fixing piece 13Ca while abutting against the outer peripheral surfaces of the metal frame 13A and the resin frame 13B. The vertical mounting piece 13Cb extends from the edge of the vertical fixing piece 13Ca located on the interior side of the room, along the visible surface of the new left vertical frame 13 facing the room, and then protrudes toward the room from a corner located on the interior side of the new left vertical frame 13.

[0015] This new left vertical frame 13 is attached to the frame B by threading an inner screw S3 into the frame B via a vertical mounting piece 13Cb that protrudes toward the room side of the vertical frame fixing bracket 13C. More specifically, for the new left vertical frame 13, a vertical inner spacer D1 that protrudes inward from the existing vertical doorstop wall 1cb is previously disposed in the existing vertical frame 1c on the part of the existing vertical frame 1c that is on the room side of the existing vertical doorstop wall 1cb, and a vertical frame reinforcement 20 and a vertical outer spacer D2 are disposed on the surface that will be on the inner side of the existing vertical main body 1ca. The vertical frame reinforcement 20 is a flat plate formed from a metal such as steel or aluminum alloy, and is attached to the position corresponding to the vertical frame fixing bracket 13C by threading a screw S4. As is clear from the figure, the dimension of the vertical frame reinforcement 20 along the projection direction is set to be approximately the same as the vertical fixing piece 13Ca of the vertical frame fixing bracket 13C. From the above-mentioned state, the vertical fixing piece 13Ca is abutted against the vertical outer spacer D2, and the internal screw S3 is screwed into the frame B via the vertical mounting piece 13Cb and the vertical inner spacer D1. At the same time, the external screw S5 is screwed into the vertical frame reinforcement 20 via the metal frame 13A of the new left vertical frame 13 and the vertical fixing piece 13Ca, thereby attaching the new left vertical frame 13 to the inner periphery of the existing vertical frame 1c. On the exterior side of the new left vertical frame 13, an external frame F is provided between the metal frame 13A and the exterior wall panel E to conceal the existing vertical frame 1c. On the indoor side of the newly installed left vertical frame 13, an inner cover H and an inner frame J are provided between the resin frame portion 13B and the existing inner frame G so as to cover and conceal the resin frame portion 13B and the vertical frame fixing bracket 13C.

[0016] As shown in Figure 2, the new lower frame 12 is attached to the inner periphery of the existing lower frame 1b with a screw S6, with the frame support member 18 already attached to the existing lower frame 1b. The new upper frame 11 is attached to the inner periphery of the existing upper frame 1a by screwing a screw S7 into the frame B via the upper frame fixing bracket 11C and screwing a screw S8 into the frame reinforcement 21 through the metal frame portion 11A, with the upper frame fixing bracket 11C already attached to the outer periphery and the upper frame reinforcement 21 already attached to the inner periphery of the existing upper frame 1a. Furthermore, as shown in Figure 3, the new right vertical frame 14 is attached to the frame B by screwing an internal screw S9 into the frame B via the portion of the vertical frame fixing bracket 14C that protrudes toward the interior of the building, with the upper frame fixing bracket 11C similar to the vertical frame fixing bracket 13C already attached to the outer periphery. An outer frame F is provided on the exterior side of the newly installed right vertical frame 14, and an inner peripheral cover H and an inner frame J are provided on the interior side, just like the newly installed left vertical frame 13.

[0017] As shown in FIG. 3, the new door panel 15 is supported by a hinge 16 interposed between the new door panel 15 and the new left vertical frame 13 so as to be able to open and close. The electric lock 30 attached to the new door panel 15 is operated by an electric actuator (not shown) and is provided at the door edge of the new door panel 15. The electric lock 30 is connected to a power source (not shown) inside the room via an internal door cable 31 arranged inside the new door panel 15, a frame-side cable 32 arranged in the new door frame 10, and a relay part 33 connecting the internal door cable 31 and the frame-side cable 32. The internal door cable 31 is led out from the electric lock 30 and then arranged inside the new door panel 15 toward the hanging point. A connector 31a is provided at the end of the internal door cable 31. The frame side cable 32 is led out from a power source inside the room (not shown) and has a connector 32a at its tip.After passing through the inner frame J of the newly installed left vertical frame 13, it is arranged sequentially inside the resin frame portion 13B and the metal frame portion 13A.

[0018] 5 to 8, the resin frame portion 13B of the new left vertical frame 13 has an interior insertion hole (interior insertion portion) 34 in the resin inner sight wall portion 13k facing the room, an intermediate through hole 35 in the partition wall portion 13h, and an interior insertion hole (interior insertion portion) 36 in the metal frame facing wall portion 13m on the exterior side facing the metal frame portion 13A. The metal frame portion 13A of the new left vertical frame 13 has an exterior insertion hole (exterior insertion portion) 37 in the resin frame facing wall portion 13n on the interior side facing the metal frame facing wall portion 13m of the resin frame portion 13B, and a component mounting hole (frame-side electrical portion) 38 in the exterior side portion of the inner periphery side sight wall portion (door facing wall portion) 13p. The indoor insertion hole 34, intermediate through-hole 35, inner insertion hole 36, outer insertion hole 37, and component mounting hole 38 are each a substantially rectangular elongated hole extending vertically, and are sized to allow the connector 32a of the frame-side cable 32 to pass therethrough. In this embodiment, the indoor insertion hole 34, intermediate through-hole 35, inner insertion hole 36, outer insertion hole 37, and component mounting hole 38 have opening ranges in the height direction set so that the frame-side cable 32 can be arranged at the same height when the connector 32a is inserted sequentially. That is, the inner insertion hole 36 is configured to have smaller vertical and horizontal dimensions than the outer insertion hole 37, and is positioned opposite the outer insertion hole 37 when the resin frame portion 13B and the metal frame portion 13A are integrated. As shown in FIG. 8 , the opening edge of the inner insertion hole 36 is located on the inner periphery of the opening edge of the outer insertion hole 37. The indoor insertion hole 34 and the intermediate through-hole 35 are formed to be the same size as the inner insertion hole 36 and are formed in positions facing each other. The component mounting hole 38, for mounting the relay component 33, is formed in a position where its height dimension is larger than that of the outer insertion hole 37 and its upper edge is approximately aligned with that of the outer insertion hole 37. Therefore, the frame-side cable 32 can be inserted sequentially at the same height through the indoor insertion hole 34, intermediate through-hole 35, inner insertion hole 36, outer insertion hole 37, and component mounting hole 38, facilitating wiring work. The relay component 33 includes mounting brackets 33b and 33c and connectors 33d and 33e at both ends of the relay cable 33a.This relay component 33 is attached to the new door panel 15 via a mounting bracket 33b with one connector 33d connected to the connector 31a of the in-door cable 31, and the other connector 33e is attached to the metal frame portion 13A of the new left vertical frame 13 via a mounting bracket 33c with the other connector 33e connected to the connector 32a of the frame-side cable 32. When the new door panel 15 is positioned in the closed position relative to the new frame body 10, the relay cable 33a is housed inside one mounting bracket 33b. When the new door panel 15 is positioned in the open position relative to the new frame body 10, the relay cable 33a is appropriately led out of the mounting bracket 33b, absorbing changes in the relative positions of the mounting brackets 33b and 33c, and maintaining the connection between the electric lock 30 and a power source (not shown).

[0019] With this fixture, the entire periphery of the opening edge of the inner insertion hole 36 formed in the resin frame portion 13B is located more inward than the opening edge of the outer insertion hole 37 formed in the metal frame portion 13A. Therefore, even if an event occurs in which the frame-side cable 32 moves inside the newly installed left vertical frame 13, the frame-side cable 32 will not come into contact with the opening edge of the outer insertion hole 37, and there is no risk of damage to the frame-side cable 32 as a result. Moreover, there is no need for a separate protective component such as a grommet, and the above-mentioned effects can be achieved simply by defining the opening ranges of the inner insertion hole 36 in the resin frame portion 13B and the outer insertion hole 37 in the metal frame portion 13A, so there is no risk of increased manufacturing costs or complicated assembly work due to an increased number of parts.

[0020] In the above-described embodiment, a fixture for renovation is exemplified, but the present invention does not necessarily have to be a fixture for renovation. Also, while the hinge 16 is provided between the vertical frame located on the left side when viewed from the inside of the room and the new door panel 15, the hinge 16 may be provided between the vertical frame on the opposite side. Furthermore, while an inner insertion hole that serves as a through hole is exemplified as the inner insertion portion, and an outer insertion hole that serves as a through hole is exemplified as the outer insertion portion, the inner insertion portion and the exterior insertion portion do not necessarily have to be through holes, and may be cutouts that are partially open to the surroundings.

[0021] In the above-described embodiment, the entire opening edge of the inner insertion portion protrudes inward beyond the opening edge of the outer insertion portion. However, the present invention is not limited to this. For example, the same effect can be achieved by having multiple opening edges of the inner insertion portion protrude inward while maintaining a gap smaller than the outer diameter of the frame-side cable. Furthermore, while an electric lock attached to a door body is illustrated as an example of an electrical component, the present invention can also be applied to wiring other electrical components attached to the door body, such as communication devices and display panels. Furthermore, the present invention can be used not only for wiring electrical components of the door body, but also for wiring automatic opening / closing devices such as entrance lights, cameras, and door closers, and delivery boxes. Furthermore, the indoor insertion hole 34, the inner insertion hole 36, the outer insertion hole 37, and the component mounting hole 38 are provided so that the frame-side cable 32 can be arranged at the same height when inserted, but the present invention is not necessarily limited to this. For example, the component mounting hole 38 may be provided in the middle of the newly installed left vertical frame 13 and connected to the relay component 33, and the indoor insertion hole 34 may be provided at the upper end of the newly installed left vertical frame 13 to allow the frame side cable 32 to be pulled out into the room.

According to this invention, since the opening edge of the inner insertion portion formed in the resin frame portion is located more inward than the opening edge of the outer insertion portion formed in the metal frame portion, it is possible to prevent damage caused by the frame-side cable coming into contact with the opening edge of the outer insertion portion without providing a separate part such as a grommet, and there is no risk of increased manufacturing costs or complicated assembly work. Note that the inner insertion portion does not necessarily have to be located more inward than the outer insertion portion along its entire circumference, as long as the frame-side cable does not come into contact with the opening edge of the outer insertion portion.
