Description

[Technical Field]

[0001] The present invention relates to an operating element used to operate a fixture, and to a fixture equipped with an operating element. [Background technology]

[0002] A fitting is provided with various operating parts. The operating parts are used by the fitting user to perform various operations on the fitting, such as locking / unlocking and opening / closing. A conventional example of such fitting is a double sash window equipped with a crescent and an operating handle as operating parts (see Patent Document 1).

[0003] In the conventional double sash described in Patent Document 1, the crescent is used to lock and unlock two sliding shoji screens, and the operating handle is used to open and close the shoji screens by sliding them. The crescent is fixed to one of the two shoji screens and engages with a bracket fixed to the other shoji screen. The operating handle is fixed to the two shoji screens and is pulled laterally when the shoji screens are slid. The crescent and operating handle are required to be strong; for example, they are made of metal. However, environmental considerations have become important in recent years, and improvements are being sought in building fixtures with operating parts to reduce environmental impact. However, operating parts of building fixtures are frequently used parts and therefore must be durable enough to withstand repeated use as well as the environment in which the fixtures are installed.

[0009] An embodiment of an operating component and fitting of the present invention will be described with reference to the drawings. The fixture of this embodiment is equipped with the operating component of this embodiment and is installed in an opening of a building. The operating component of the fixture is provided on the fixture and is used to operate the fixture. The fixture is installed between the interior (indoor) and exterior (outdoor) of a building and is operated by the operating component.

[0010] (First embodiment) Fig. 1 is a front view showing the fitting 1 of the first embodiment, showing the fitting 1 installed in a building as seen from inside the room. Fig. 2 is a longitudinal cross-sectional view showing the fitting 1 of the first embodiment, showing the fitting 1 cut along a plane including the up-down direction R and the indoor-outdoor direction T. Fig. 3 is a transverse cross-sectional view showing the fitting 1 of the first embodiment, showing the fitting 1 cut along a plane including the left-right direction S and the indoor-outdoor direction T.

[0011] When viewing the fitting 1 installed in a building from the front, the direction that is up and down is the up-down direction R, and the direction that is left and right is the left-right direction S. In Figure 1, the up-down direction R is the vertical direction, and the left-right direction S is the horizontal direction. The indoor / outdoor direction T is the indoor / outdoor direction (indoor / outdoor direction) of the fitting 1 installed in a building. Furthermore, the indoor / outdoor direction T is the front-to-back direction (depth direction) and the thickness direction of the fitting 1 when viewed from the front of the fitting 1 installed in a building, and in Figure 3 is the horizontal direction perpendicular to the left-to-right direction S. In this way, the directions related to the fitting 1 are specified by the directions when it is installed in a building. Furthermore, the indoor side and outdoor side of the fitting 1 are the indoor side and outdoor side when it is installed in a building.

[0012] As shown in the figure, the fitting 1 is a sliding window, and comprises two sliding shoji screens 2 and 3 (first shoji screen 2 and second shoji screen 3) that can be opened and closed, and a frame body 4 that surrounds the shoji screens 2 and 3. The shoji screens 2 and 3 open and close an opening 4A in the frame body 4. The frame body 4 is a rectangular opening frame (window frame), and the opening 4A of the frame body 4 is formed in a rectangular shape inside the frame body 4. The frame body 4 also has four frames 10 to 13 (an upper frame 10, a lower frame 11, and a pair of vertical frames 12 and 13) that are fitted together, and the frames 10 to 13 form the opening 4A.

[0013] The frames 10 to 13 of the frame body 4 are frame components that make up the frame body 4, and are each made of a shaped member (extruded shaped member) formed by extrusion molding. The upper frame 10 and lower frame 11 are the upper and lower horizontal frames of the frame body 4, and extend in the horizontal direction (left-right direction S) at the top and bottom of the frame body 4. The pair of vertical frames 12 and 13 are side frames located on the left and right sides of the frame body 4, and extend in the vertical direction (up-down direction R) at the sides of the frame body 4. The ends of the upper frame 10, the lower frame 11, and the left and right vertical frames 12 and 13 are connected to form the frames 10 to 13.

[0014] The shoji screens 2 and 3 are movable sliding screens that move by sliding, and are arranged so as to be movable (slidable) in the left-right direction S in the opening 4A of the frame body 4. The shoji screens 2 and 3 slide in the left-right direction S in the opening 4A of the frame body 4 in a double sliding manner. The opening 4A of the frame body 4 is opened and closed by the sliding of each of the shoji screens 2 and 3. Of the two shoji screens 2 and 3, the first shoji screen 2 is an inside shoji screen (inner shoji screen) located on the inside of the room, and the other, the second shoji screen 3, is an outside shoji screen (outer shoji screen) located on the outside of the room. The shoji screens 2 and 3 open and close by sliding in the opening and closing directions (opening direction, closing direction).

[0015] Each of the shoji screens 2, 3 has a rectangular frame 20, 30 and panels 21, 31 arranged inside the frame 20, 30. The panels 21, 31 are made of glass (double glazing in this case) and are fitted into the frame 20, 30, respectively. The frame 20 of the first shoji screen 2 has four frames 22-25 (upper frame 22, lower frame 23, door edge frame 24, and joint frame 25) that are fitted together, and the frame 30 of the second shoji screen 3 has four frames 32-35 (upper frame 32, lower frame 33, door edge frame 34, and joint frame 35) that are fitted together. The frames 22 to 25 and 32 to 35 are frame constituent members that make up the frame bodies 20 and 30, and are each made of a shaped member formed by extrusion molding.

[0016] The upper frames 22, 32 and the lower frames 23, 33 are the horizontal frames on the top and bottom of the frames 20, 30, and extend horizontally at the top and bottom of the frames 20, 30. The end frames 24, 34 and the joint frames 25, 35 are the left and right vertical frames (side frames) located on the left and right sides of the frames 20, 30, respectively, and extend vertically at the sides of the frames 20, 30. The ends of the frames 22-25 and the frames 32-35 are connected to each other, forming frames for the frames 22-25 and the frames 32-35, respectively.

[0017] The door frame 25 of the first shoji screen 2 is an interior door frame (interior door frame) located on the interior side of the room, and the door frame 35 of the second shoji screen 3 is an exterior door frame (exterior door frame) located on the exterior side of the room. When the pair of shoji screens 2, 3 are closed, the door frame frames 25, 35 of the pair of shoji screens 2, 3 overlap in the indoor-outdoor direction T and are closed facing each other. In addition, the door edge frames 24, 34 of the shoji screens 2, 3 are arranged along the left and right vertical frames 12, 13.

[0018] The fitting 1 is equipped with a locking device 40 that locks the shoji screens 2 and 3. The locking device 40 is a crescent, and has a crescent lock 41 provided on the first shoji screen 2 and a crescent receiver 42 provided on the second shoji screen 3 that receives the crescent lock 41. The crescent lock 41 is an operating part (lock part) of the locking device 40 attached to the joint frame 25 of the first shoji screen 2, and the crescent receiver 42 is a lock receiving part of the locking device 40 attached to the joint frame 35 of the second shoji screen 3. When the pair of shoji screens 2 and 3 are closed, the crescent lock 41 is received in and engaged with the crescent receiver 42, locking the locking device 40 and the shoji screens 2 and 3. When the crescent lock 41 is released from the crescent receiver 42, the locking device 40 and the shoji screens 2 and 3 are unlocked. The pair of shoji screens 2 and 3 are locked and unlocked by the locking device 40.

[0019] The crescent lock 41 of the locking device 40 is a type of operating part of the fitting 1. An operating part is a part that is provided on the fitting 1 and is operated by a user of the fitting 1. An operating part is also a part that is used to operate an operation target of the fitting 1, and for example, the operating part operates the locking / unlocking and opening / closing of the fitting 1. The operating part is used to operate at least one of locking / unlocking and opening / closing of the fitting 1, and operates at least one of locking / unlocking and opening / closing of the fitting 1. An operating part is also used to operate a component of the fitting 1 that makes up the fitting 1. For example, the component of the fitting 1 is the locking device 40, an opening / closing device, or an opening / closing body, and the opening / closing body is a shoji screen 2, 3, a door body, or a panel body. An operating part is used to operate the locking device 40, opening / closing device, or opening / closing body of the fitting 1, and operates the locking device 40, opening / closing device, or opening / closing body of the fitting 1.

[0020] Here, the operating part of the fitting 1 is a crescent lock 41 used to lock and unlock the fitting 1. The crescent lock 41 is a locking / unlocking operating part, and is used by the user of the fitting 1 to lock and unlock the shoji screens 2 and 3 that are the opening and closing bodies of the fitting 1. The crescent lock 41 is operated by the user and rotates between a locked position where it engages with the crescent receiver 42 and an unlocked position where it disengages from the crescent receiver 42, and is placed in the locked position and the unlocked position.

[0021] The user rotates the crescent lock 41 to the locked position, and uses the crescent lock 41 to lock the locking device 40, thereby locking the shoji screens 2 and 3 and the fitting 1. The user also rotates the crescent lock 41 to the unlocked position, and uses the crescent lock 41 to unlock the locking device 40, thereby unlocking the shoji screens 2 and 3 and the fitting 1. In this way, the crescent lock 41 is used to lock and unlock the locking device 40, the shoji screens 2 and 3, and the fitting 1.

[0022] FIG. 4 is a perspective view showing the crescent lock 41 of the fitting 1 of the first embodiment. As shown in the figure, the crescent lock 41, which is an operating part, has a wooden part 43 (the part hatched in a grid pattern with a chain line). The wooden part 43 is provided on at least a part (partially or entirely) of the crescent lock 41, and constitutes at least a part of the crescent lock 41. The crescent lock 41 also has a contact part 44 that the user's hand comes into contact with when operating the crescent lock 41, and the contact part 44 of the crescent lock 41 is the wooden part 43. When operating the fitting 1 (locking device 40, shoji screens 2, 3) using the crescent lock 41, the user's hand comes into contact with the contact part 44. At least a part of the contact part 44 is the wooden part 43.

[0023] The crescent lock 41 has a surface layer 45 provided on the surface of the wooden part 43. The surface layer 45 is a coating layer that coats the surface of the wooden part 43 and covers the surface of the wooden part 43. The surface of the wooden part 43 is subjected to a surface treatment (coating treatment), and the surface layer 45 is formed on the surface of the wooden part 43. For example, the surface treatment is a painting treatment in which a coating agent is applied, a lamination treatment in which a laminate film is attached, or a transfer treatment in which a transfer sheet is transferred, and the surface layer 45 is a coating agent layer, a laminate film layer, or a transfer sheet layer. The surface layer 45 is also a protective layer that protects the surface of the wooden part 43, or an odor-preventing layer that prevents odors from being generated from the wooden part 43. The surface layer 45, which is a protective layer, protects the surface of the wooden part 43 from dirt or scratches, preventing the surface of the wooden part 43 from becoming dirty or scratched.

[0024] The ratio (volume %) of the volume of the wooden part 43 to the total volume of the crescent lock 41 (operating part) is 50% or more. Thus, the volume % of the wooden part 43 is 50% or more and 100% or less of the total volume of the crescent lock 41. Here, the contact part 44 of the crescent lock 41 is a knob part that is gripped with the fingers when operating (rotating) the crescent lock 41. Furthermore, the entire contact part 44 is the wooden part 43, and at least the contact part 44 of the crescent lock 41 is the wooden part 43. The parts of the crescent lock 41 other than the wooden part 43 are made of metal or synthetic resin.

[0025] The wood part 43 is made of modified wood, which is wood that has been subjected to a durability treatment. Modified wood is wood that has been subjected to a durability treatment (modification treatment) that modifies (improves) the durability of raw wood (raw wood), and is produced by subjecting wood to a durability treatment. The durability of wood includes, for example, rot resistance, weather resistance, termite resistance, and strength. In this way, modified wood is wood whose durability has been modified (improved) by a durability treatment, which is a durability modification treatment. The modified wood is processed to produce the wood part 43 and contact part 44, which have durability. The durability of the wood part 43 and contact part 44 made of modified wood is higher than the durability of the raw wood.

[0026] Here, durability treatment of wood refers to chemical treatment of wood, and modified wood refers to chemically treated wood that has been chemically treated or compressed chemically treated wood. Chemical treatment of wood refers to chemical treatment that modifies the durability of wood (raw wood), and chemically treated wood refers to wood whose durability has been modified by chemical treatment. Compressed chemically treated wood refers to wood that has been compressed and densified by compressing chemically treated wood. Chemically treated wood is produced by chemically treating wood, and compressed chemically treated wood (densified chemically treated wood) is produced by compressing chemically treated wood.

[0027] Chemical treatments of wood include, for example, acetylation treatment, which acetylates wood, formalization treatment, which formalizes wood, phenolic resin treatment, which impregnates wood with a phenolic resin, acrylic resin treatment, which impregnates wood with an acrylic resin, and furan resin treatment, which converts furfuryl alcohol impregnated into wood into a furan resin. Thus, chemically treated wood includes, for example, acetylated wood (acetylated wood), formalized wood (formalized wood), phenolic resin-treated wood, acrylic resin-treated wood, and furan resin-treated wood.

[0028] In the fitting 1 described above, the crescent lock 41 is provided with a wood section 43 made of modified wood, and a highly durable crescent lock 41 can be realized using naturally derived materials. This ensures the durability of the crescent lock 41, which is the operating part of the fitting 1, while reducing the environmental impact of the crescent lock 41 and the fitting 1. Furthermore, the modified wood of the wood section 43 is chemically treated wood or compressed chemically treated wood, so the durability of the crescent lock 41 of the fitting 1 can be ensured over the long term.

[0029] By providing a wooden portion 43 on the crescent lock 41, which is visible when locking or unlocking, it is possible to improve the design of the crescent lock 41 and the fitting 1 to which the crescent lock 41 is attached. Also, by making the contact portion 44 of the crescent lock 41 the wooden portion 43, it is easier to recognize that wood is used in the crescent lock 41 of the fitting 1, and it is possible to improve the design of the crescent lock 41 and the fitting 1 to which the crescent lock 41 is attached.

[0030] If the volume percentage of the wooden part 43 of the crescent lock 41 is less than 50 volume %, the volume of the wooden part 43 will be small relative to the overall volume of the crescent lock 41, and there is a risk that the wooden part 43 will not stand out in the crescent lock 41. In contrast, by making the volume percentage of the wooden part 43 50 volume % or more, the wooden part 43 will be more noticeable in the crescent lock 41, and the design of the crescent lock 41 can be improved.

[0031] By covering the surface of the wooden part 43 of the crescent lock 41 with the surface layer 45, properties can be easily added to the wooden part 43. For example, the surface layer 45 can improve the stain resistance or scratch resistance of the wooden part 43, protecting the surface of the wooden part 43 from stains or scratches. The surface layer 45 can also improve the odor resistance of the wooden part 43, preventing odors from being generated from the wooden part 43. In particular, chemically treated wood tends to retain a chemical odor due to the chemical treatment of the wood. In contrast, the surface layer 45 can prevent chemical odors from being generated from the wooden part 43 made of chemically treated wood or compressed chemically treated wood.

[0032] The operating parts used to lock and unlock the fixture 1 are not limited to the crescent lock 41, but may be other operating parts (for example, a thumb turn). The fixture 1 is not limited to a sliding window, but may be other fixtures equipped with operating parts (for example, windows other than sliding windows, doors). The present invention can be applied to operating parts for various fixtures.

[0033] (Second embodiment) Next, the operation components and fixtures of the second embodiment will be described. Regarding the operation components and fixtures of the second embodiment, differences from the operation components (crescent lock 41) and fixture 1 of the first embodiment will be mainly described. Furthermore, regarding the operation components and fixtures of the second embodiment, the same names as the operation components and fixtures of the first embodiment will be used for the configurations that correspond to the configurations of the operation components and fixture 1 of the first embodiment.

[0034] Fig. 5 is a front view showing the fitting 5 of the second embodiment, showing the fitting 5 installed in a building as viewed from inside the room. Fig. 6 is a longitudinal cross-sectional view showing the fitting 5 of the second embodiment, showing the fitting 5 cut along a plane including the up-down direction R and the indoor-outdoor direction T. Fig. 7 is a transverse cross-sectional view showing the fitting 5 of the second embodiment, showing the fitting 5 cut along a plane including the left-right direction S and the indoor-outdoor direction T.

[0035] As shown in the figure, the fitting 5 is a vertical sliding window, and comprises an openable and closable shoji screen 6, which is a vertical sliding shoji screen, and a frame body 7 surrounding the shoji screen 6. An opening 7A in the frame body 7 is opened and closed by the shoji screen 6. The frame body 7 is configured in the same manner as the frame body 4 of the first embodiment, and has four frames 50 to 53 (an upper frame 50, a lower frame 51, and a pair of vertical frames 52, 53).

[0036] The shoji screen 6 is a movable shoji screen that moves (opens and closes) by rotating, and is connected to the frame body 7 so that it can rotate (open and close) and is placed in an opening 7A of the frame body 7. The shoji screen 6 opens by rotating from the opening 7A of the frame body 7 toward the outside of the room, and closes by rotating from the outside of the frame body 7 toward the inside of the room. The opening 7A of the frame body 7 is opened and closed by the rotation of the shoji screen 6.

[0037] The shoji screen 6 has a rectangular frame 60 and a panel 61 arranged inside the frame 60. The frame 60 has four frames 62 to 65 (top frame 62, bottom frame 63, leading frame 64, and trailing frame 65) that are fitted together. The top frame 62 and bottom frame 63 are the horizontal frames on the top and bottom of the frame 60, while the leading frame 64 and trailing frame 65 are the vertical frames (side frames) on the left and right of the frame 60. The leading frame 64 is located at the leading end of the shoji screen 6, and the trailing frame 65 is located at the trailing end of the shoji screen 6.

[0038] The fitting 5 is equipped with a cam latch handle 70 provided on a shoji screen 6. A base material 71 is fixed to the door frame 64 of the shoji screen 6, and the cam latch handle 70 is rotatably attached to the base material 71. The cam latch handle 70 is one of the operating parts of the fitting 5, and is connected to the door frame 64 and the shoji screen 6 via the base material 71. The cam latch handle 70 is used to both lock and unlock and open and close the fitting 5, and operates both the locking and unlocking and opening and closing of the fitting 5. When the shoji screen 6 is closed, the cam latch handle 70 rotates, and the shoji screen 6 is locked by the cam latch handle 70. Also, when the cam latch handle 70 rotates, the shoji screen 6 is unlocked. The shoji screen 6 is locked and unlocked by the cam latch handle 70.

[0039] The cam latch handle 70 is a component for locking, unlocking, and opening and closing, and is used by the user of the fitting 5 to lock and unlock the shoji screen 6, which is the opening and closing body of the fitting 5, as well as to open and close the shoji screen 6. The cam latch handle 70 is operated by the user to rotate to a locking position where the shoji screen 6 is locked and an unlocking position where the shoji screen 6 is unlocked, and is positioned at the locking position and the unlocking position.

[0040] The user rotates the cam latch handle 70 to the locked position, and uses the cam latch handle 70 to lock the shoji screen 6 and the fitting 5. The user also rotates the cam latch handle 70 to the unlocked position, and unlocks the shoji screen 6 and the fitting 5. In this state, the user pushes the cam latch handle 70 toward the outside of the room, opening the shoji screen 6 toward the outside via the cam latch handle 70, and pulls the cam latch handle 70 toward the inside of the room, closing the shoji screen 6 toward the inside via the cam latch handle 70. In this way, the cam latch handle 70 is used to lock, unlock, open and close the shoji screen 6 and the fitting 5.

[0041] FIG. 8 is a perspective view showing a cam latch handle 70 of the fitting 5 of the second embodiment. As shown in the figure, the cam latch handle 70, which is an operating part, has a wooden portion 72 (the portion indicated by a chain line with grid-like hatching). The wooden portion 72 is provided on at least a portion (partially or entirely) of the cam latch handle 70, and constitutes at least a part of the cam latch handle 70. The cam latch handle 70 also has a contact portion 73 that a user's hand comes into contact with when operating the cam latch handle 70, and the contact portion 73 of the cam latch handle 70 is the wooden portion 72. When operating a fitting 5 (shoji screen 6) using the cam latch handle 70, the hand of the user of the fitting 5 comes into contact with the contact portion 73. At least a portion of the contact portion 73 is the wooden portion 72. The cam latch handle 70 has a surface layer 74 provided on the surface of the wooden portion 72, and the surface layer 74 covers the surface of the wooden portion 72.

[0042] The ratio (volume %) of the volume of the wooden portion 72 to the overall volume of the cam latch handle 70 (operating part) is 50% or more. Thus, the volume % of the wooden portion 72 is 50% or more and 100% or less of the overall volume of the cam latch handle 70. Here, the contact portion 73 of the cam latch handle 70 is a gripping portion (handle) that is gripped by hand when operating (rotating) the cam latch handle 70 and when opening and closing the shoji screen 6 using the cam latch handle 70. In addition, the entire contact portion 73 is the wooden portion 72, and at least the contact portion 73 of the cam latch handle 70 is the wooden portion 72.

[0043] The wooden portion 72 of the cam latch handle 70 is made of modified wood, just like the wooden portion 43 of the crescent lock 41. Therefore, the cam latch handle 70 and fitting 5 of the second embodiment can achieve the same effects as the crescent lock 41 and fitting 1 of the first embodiment. Note that the operating part used to lock, unlock, and open / close the fitting 5 is not limited to the cam latch handle 70, and may be another operating part. Furthermore, the fitting 5 may be provided with an operating part (opening / closing operating part) (for example, a handle or pull tab) that is used only to open and close the fitting 5.
