Description

[Technical Field]

[0001] The present invention relates to a lock operating device for fittings for operating a lock device provided in fittings. [Background technology]

[0002] In fittings in which a shoji screen is supported on a frame so that it can be opened and closed, a locking device is provided between the frame and the shoji screen. When the locking device is locked with the shoji screen in the closed position on the frame, it prevents the shoji screen from moving open relative to the frame, and when the locking device is unlocked, it allows the shoji screen to move open relative to the frame. Examples of locking / unlocking devices include those provided on the vertical frame of the shoji screen. Examples of locking / unlocking devices include a base attached to the visible surface on the interior side of the vertical frame, and a lever member rotatably supported on the base via an axis member extending in the visible direction. In this type of locking device, when the lever member is rotated relative to the base, an output unit operates, allowing the locking device linked to the output unit to be locked or unlocked (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-279983 Summary of the Invention [Problem to be solved by the invention]

[0004] Since the lock operating device described above protrudes from the interior facing surface of the vertical stile, it is desirable to minimize the protrusion. However, reducing the protrusion can lead to situations where the lever member becomes difficult to grip when positioned along the vertical stile's facing surface, impairing operability. This situation is also true when the base is attached to the interior facing surface of the frame.

[0005] In view of the above-mentioned circumstances, the present invention aims to provide a lock operating device for building fixtures that can reduce the protruding dimension from a profile without impairing operability. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the lock operating device for building materials of the present invention comprises a base attached to the interior facing surface of a shaped member that constitutes a shoji screen or frame body, a lever member rotatably supported on the base via an axis member in the facing direction interposed between the base and the lever member, and an output unit connected to the lever member.The lock operating device for building materials operates the output unit by rotating the lever member around the axis of the axis member relative to the base, thereby locking and unlocking the locking device between the frame body and the shoji screen.The lever member has an axis support portion that protrudes to one side from the tip of the handle portion, and the axis member is provided on the axis support portion.The lever member is rotatably supported on the base with at least a portion of the axis support portion positioned outside the interior facing surface of the shaped member. [Effects of the Invention]

[0007] According to the present invention, the tip of the grip has a shaft support portion that protrudes to one side, and the lever member is supported on the base via this shaft support portion. Therefore, even when the grip is in a position along the find surface, it is possible to provide a gap between the grip and the find surface, preventing a situation in which operability is impaired from this position. Moreover, because the lever member is supported on the base with the shaft support portion positioned on the outside of the interior find surface of the extrusion, it is possible to reduce the protrusion dimension from the extrusion.

DETAILED DESCRIPTION OF THE INVENTION

[0009] A preferred embodiment of a lock operating device for fittings according to the present invention will be described in detail below with reference to the accompanying drawings. For convenience, the terms "prospect direction" and "finding direction" will be used below. The "prospect direction" is the direction along the depth of the fitting, as indicated by arrow A in the drawing. A surface along the prospect direction may be referred to as a "prospect surface." The "finding direction" is the vertical direction perpendicular to the prospect direction for items that extend horizontally, such as a sill. For items that extend vertically, such as a vertical frame, the horizontal direction perpendicular to the prospect direction is referred to as a "finding direction." A surface along the prospect direction may be referred to as a "finding surface."

[0010] FIG. 1 shows a fixture to which a lock operating device according to an embodiment of the present invention is applied. The fixture illustrated here is a casement window comprising a frame 1 and a shoji screen 10 rotatably supported on an axis extending vertically relative to the frame 1. The frame 1 is constructed by assembling an upper frame 1a, a lower frame 1b, and left and right vertical frames 1c and 1d around the four sides. The shoji screen 10 is constructed by attaching an upper frame 12, a lower frame 13, and left and right vertical frames 14 and 15 to a panel 11, such as a double-glazed glass panel, around the four sides. The upper frame 1a, lower frame 1b, and vertical frames 1c and 1d that constitute the frame 1, and the upper frame 12, lower frame 13, and vertical frames 14 and 15 that constitute the shoji screen 10 are extruded shapes molded from metals such as aluminum alloys or resin, each of which has a substantially uniform cross-sectional shape along its entire length. In this embodiment, the shoji screen 10 is supported on the frame body 1 so that it can be opened and closed by hinges and link mechanisms (not shown) provided between the frame body 1 and the shoji screen 10, so that the vertical frame located on the right side as viewed from inside the room (hereinafter referred to as the right side as viewed from inside the room) (hereinafter referred to as the right vertical frame 14 when distinguishing) is the hanging point, and the vertical frame located on the left side as viewed from inside the room (hereinafter referred to as the left side as viewed from inside the room) (hereinafter referred to as the left vertical frame 15 when distinguishing) is the door edge.

[0011] As shown in Figures 2 and 3, the left vertical frame (shaped member) 15, which forms the door end, has a frame body 15a, an inner sight wall 15b, and an outer sight wall 15c. The frame body 15a is cylindrical with a roughly rectangular cross section. A guide groove 15d is provided along the length of the outer peripheral surface of the frame body 15a facing the left vertical frame 1d. The inner sight wall 15b extends in the sight direction on the inside of the frame body 15a, while the outer sight wall 15c extends in the sight direction on the outside of the frame body 15a. The inner sight wall 15b protrudes outward from the frame body 15a, while the outer sight wall 15c protrudes inward from the frame body 15a. Although not shown in the figure, a ledge is attached to the inner periphery of the frame body 15a on the indoor side, and the panel 11 is supported between the ledge and the outer visible wall portion 15c.

[0012] A locking device 20 is provided between the frame 1 and the shoji screen 10. When the locking device 20 is locked with the shoji screen 10 in the closed position relative to the frame 1, it prevents the shoji screen 10 from moving open relative to the frame 1, but when it is unlocked, it allows the shoji screen 10 to move open. In this embodiment, the locking device 20 is configured with a locking bar (operated member) 21 slidably disposed in the guide groove portion 15d of the left vertical frame 15. That is, the locking bar 21 is provided with a locking pin 22 that protrudes toward the left vertical frame 1d. Meanwhile, a pin receiver (not shown) is provided in the left vertical frame 1d at a position corresponding to the locking pin 22. In this locking device 20, when the locking bar 21 slides in one direction (upward in the illustrated example) relative to the left vertical frame 15, the locking pin 22 engages with the pin receiver as the locking bar 21 slides, thereby establishing a locked state. On the other hand, when the lock bar 21 slides in the other direction (downward in the illustrated example) relative to the left vertical frame 15, the engagement between the lock pin 22 and the pin receiver is released, resulting in an unlocked state. The lock operating device 30 locks and unlocks the lock device 20 by moving the lock bar 21, which is arranged on the left vertical frame 15, back and forth along its length, and as shown in Figures 4 to 12, includes a main base portion 31, an auxiliary base portion 32, a lever member 33, an arm member (output portion) 34, and a slide member (output portion) 35.

[0013] The main base 31 serves as the base for the lock operating device 30 and includes a base body 31a, a bearing 31b, and an operating section 31c. The base body 31a is flat and extends along the length of the left vertical frame 15. The middle section of the base body 31a is narrower than the ends due to the provision of an arm notch 31d on the left edge. The bearing 31b is disc-shaped with a bearing hole 31e in its center. This bearing 31b protrudes toward the interior and exterior of the room from the edge of the arm notch 31d on the base body 31a, with the bearing hole 31e positioned approximately horizontally along the viewing direction. The bearing hole 31e of the bearing 31b is located closer to the interior than the base body 31a. An arc-shaped arm cover 31f protrudes from the interior circumferential portion of the bearing 31b toward the left side of the room. A lever notch 31g is provided in the base body 31a in a portion that is to the right of the bearing portion 31b when viewed from the inside of the room. The lever notch 31g is cut out along a circumference that coincides with the periphery of the bearing portion 31b. The operating portion 31c protrudes upward from the upper end of the base body 31a and is configured to protrude further into the room than the base body 31a. Recesses 31h are provided on both sides of the operating portion 31c so that they open to the sides and the outside of the room. In other words, by providing recesses 31h on the indoor-facing edges of both sides of the operating portion 31c, finger hooks 31i are configured to protrude laterally. Screw insertion holes 31j are provided along the projection direction at both the upper and lower ends of the base body 31a and at the upper end of the operating portion 31c.

[0014] The auxiliary base 32, together with the main base 31, constitutes the base 36 and includes an auxiliary base plate 32a, a reinforcing plate 32b, a back plate 32c, and a guide plate 32d. The auxiliary base plate 32a is a plate-shaped member extending in the forward direction and is positioned to cover the left-side surface of the bearing 31b (as viewed from the interior) and the left-side surface of the arm notch 31d (as viewed from the interior) of the base body 31a. An auxiliary bearing hole 32e is provided in the auxiliary base plate 32a facing the bearing hole 31e of the bearing 31b, so that their axes are aligned. The reinforcing plate 32b extends vertically along the interior-side surface of the base body 31a from a portion of the auxiliary base plate 32a that protrudes further toward the interior than the base body 31a. Mounting plates 32f are provided at the upper and lower ends of the reinforcing plate 32b to cover the screw insertion holes 31j of the main base 31a. Auxiliary screw insertion holes 32g are provided in the mounting plate portion 32f in the portions facing the screw insertion holes 31j of the main base portion 31, with their axes aligned. The back plate portion 32c bends from the outdoor-side edge of the auxiliary base plate portion 32a to the right as viewed from the room and extends in the forward direction, thereby facing the outdoor-side surface of the base body 31a. The guide plate portion 32d bends from the extended edge of the back plate portion 32c toward the outdoor side and extends in the forward direction. Two elongated guide holes 32h are provided in the guide plate portion 32d along the length of the left vertical frame 15. The guide holes 32h are arranged side by side along the length of the left vertical frame 15 so as to be symmetrical to each other with respect to an imaginary horizontal plane passing through the axis of the auxiliary bearing hole 32e.

[0015] The lever member 33 serves as the input portion of the lock operating device 30 and has a grip portion 33a and a shaft support portion 33b. The grip portion 33a extends linearly. The dimension of the grip portion 33a along the plate thickness direction is configured to be smaller than the outer diameter of the bearing portion 31b in the main base portion 31. The dimension of the grip portion 33a along the projection direction is approximately the same as the base body 31a of the main base portion 31. The outer surface 33c of the grip portion 33a is configured to be flat. In contrast, a storage portion 33d is provided on the inner surface of the grip portion 33a. The storage portion 33d is a recessed portion whose both side edges and tip end are closed on the inner surface of the grip portion 33a and which is open to the inner side of the grip portion 33a and the base end side of the grip portion 33a. The shaft support portion 33b is cylindrical and has a shaft member 33e at its center. The shaft member 33e is twisted perpendicular to the extension direction of the grip portion 33a at the base end of the grip portion 33a. The outer surface 33c of the grip portion 33a extends tangentially to the cylindrical shaft support portion 33b. The outer diameter of the shaft support portion 33b is slightly smaller than the bearing portion 31b of the main base 31. The dimension of the shaft support portion 33b along the projection direction is approximately the same as the width of the portion of the base body 31a located to the right of the bearing portion 31b when viewed from the room side. The shaft support portion 33b is located at the base end of the grip portion 33a, protruding toward the inner surface of the grip portion 33a and protruding from the base end of the grip portion 33a. As is clear from the figure, in this embodiment, the shaft support portion 33b is provided on the right side of the grip portion 33a as viewed from the interior, and the aforementioned shaft member 33e extends from the left end face of the shaft support portion 33b along the projection direction. The shaft member 33e has a first shaft portion 33f protruding from the end face of the shaft support portion 33b and an arm fitting shaft portion 33g protruding from the end face of the first shaft portion 33f. The first shaft portion 33f is cylindrical with an outer diameter that matches the bearing hole 31e provided in the bearing portion 31b. The dimension along the axis of the first shaft portion 33f is configured to be larger than the combined thickness of the bearing portion 31b and the auxiliary base portion 32a. The arm fitting shaft portion 33g has a square cross section and is located at a position where its center coincides with the axis of the first shaft portion 33f. The diagonal of the arm fitting shaft portion 33g is configured to be slightly smaller than the outer diameter of the first shaft portion 33f.The dimension of the arm fitting shaft portion 33g along the axial direction is approximately equal to the plate thickness of the arm member 34, which will be described later.

[0016] The arm member 34 is a plate-like member with both ends formed into an arc shape. An axis fitting hole 34a is provided at the base end of the arm member 34, and a linking pin 34b is provided at the tip end of the arm member 34. The axis fitting hole 34a is a square through-hole into which the arm fitting shaft portion 33g of the shaft member 33e can be fitted. The linking pin 34b extends in the viewing direction and protrudes to the right from the right side of the arm member 34 as seen from the room. As is clear from the figure, the arm member 34 is bent in a crank shape at its middle portion, and the tip end is configured to be shifted to the right as seen from the room relative to the base end.

[0017] The sliding member 35 has a sliding plate portion 35a and a connecting plate portion 35b. The sliding plate portion 35a is flat and has two guide pins 35c. The guide pins 35c are arranged in parallel along the length of the left vertical frame 15 and are movably inserted into the guide plate portion 32d of the auxiliary base portion 32. The guide pins 35c move along the guide holes 32h, allowing the sliding plate portion 35a to move up and down at a portion located on the left side of the guide plate portion 32d of the auxiliary base portion 32 as viewed from the room. A connecting groove 35d is provided in the sliding plate portion 35a at a portion intermediate the guide holes 32h. The connecting groove 35d extends along the forward direction and allows the connecting pin 34b of the arm member 34 to be inserted therethrough. The connecting plate portion 35b serves as a connection to the lock bar 21 and is provided on the outdoor side of the sliding plate portion 35a. The connecting plate portion 35b has screw insertion holes 35e at both upper and lower ends.

[0018] The main base 31, auxiliary base 32, lever member 33, arm member 34, and slide member 35 are assembled by overlapping auxiliary base 32 with bearing 31b of main base 31, and then inserting shaft 33e of lever member 33 through bearing hole 31e of bearing 31b and auxiliary bearing hole 32e of auxiliary base 32a from the right side of the room. Arm member 34 is connected to the inserted shaft 33e by fitting arm fitting shaft 33g into shaft fitting hole 34a. Furthermore, by inserting linking pin 34b of arm member 34 into linking groove 35d, lock operating device 30 can be constructed.

[0019] In this lock operating device 30, when the lever member 33 is rotated about the axis of the shaft member 33e relative to the base 36, the arm member 34 fitted to the arm fitting shaft portion 33g via the shaft fitting hole 34a rotates about the axis of the shaft member 33e, and the slide member 35 linked to the tip of the arm member 34 moves up and down along the extension direction of the base 36. That is, when the grip portion 33a of the lever member 33 is positioned in a first position along the base main body 31a, the link pin 34b of the arm member 34 moves above the shaft member 33e, and the slide member 35 is positioned at the uppermost position relative to the auxiliary base portion 32. From this position, when the tip of the lever member 33 is rotated so as to be pulled up and the grip portion 33a is moved gradually downward toward the room to a second position, the link pin 34b of the arm member 34 moves below the shaft member 33e, and the slide member 35 is positioned at the lowermost position.

[0020] To attach this lock operating device 30 to the shoji screen 10, a notch 15e and a stile screw insertion hole 15f are formed in the visible surface of the left vertical frame 15 facing the room. The notch 15e is large enough to allow the back plate 32c, guide plate 32d, tip of the arm member 34, and slide member 35 of the auxiliary base 32 to pass through and to allow the arm member 34 to rotate and the slide member 35 to move back and forth, and is formed in the inner visible wall 15b at a position closer to the outer periphery than the stile main body 15a. The stile screw insertion hole 15f is located in a position that corresponds to the screw insertion hole 31j provided in the lock operating device 30 when the back plate 32c, guide plate 32d, and arm member 34 of the lock operating device 30 are inserted into the notch 15e. The back plate 32c, guide plate 32d, tip of arm member 34, and slide member 35 of auxiliary base 32 are inserted into notch 15e, and base body 31a is brought into contact with interior facing surface 15g. From this state, a screw is inserted into stile screw insertion hole 15f of left vertical stile 15 via auxiliary screw insertion hole 32g of auxiliary base 32 and screw insertion hole 31j of main base 31, and the screw is threaded into nut plate 37, thereby maintaining the lock operating device 30 attached to left vertical stile 15. At the portion inserted through notch 15e, a screw S1 is threaded into lock bar 21 via screw insertion hole 35e provided in connecting plate portion 35b of slide member 35, thereby connecting slide member 35 and lock bar 21. Furthermore, in this embodiment, an upper cover 38 is attached to the portion of operating unit 31c facing the exterior so as to cover the screw member, and a lower cover 39 is attached to base body 31a. Lower cover 39 is further provided with an arm cover portion 39a that covers the base end of arm member 34 and a lever cover portion 39b that covers shaft support portion 33b of lever member 33. A red mark 40 is applied to a portion of lower cover 39 that is exposed only when lever member 33 is in the second position.

[0021] When the shoji screen 10 is in the closed position relative to the frame 1 and the lever member 33 is positioned in the first position, the lock bar 21 moves upward relative to the left vertical stile 15 via the arm member 34 and slide member 35. As a result, the lock pin 22 engages with the pin receiver and enters the locked state, restricting the opening and closing movement of the shoji screen 10 relative to the frame 1 and maintaining the shoji screen 10 in the closed position. On the other hand, when the lever member 33 is operated to move the locking device 20 from the locked state to the second position, the lock bar 21 moves downward relative to the left vertical stile 15 via the arm member 34 and slide member 35. As a result, the lock pin 22 is disengaged from the pin receiver and enters the unlocked state, allowing the shoji screen 10 to be opened or closed relative to the frame 1. Therefore, from this state, for example, by gripping the operating portion 31c provided on the lock operating device 30 and applying an operating force to the shoji screen 10, the shoji screen 10 can be opened relative to the frame 1.

[0022] As described above, when the lever member 33 is in the first position, the grip portion 33a of the lock operating device 30 is aligned with the base 36, reducing the protruding dimension of the lever member 33 compared to when the lever member 33 is in the second position. Furthermore, the lever member 33 has a shaft support portion 33b that protrudes from the base end of the grip portion 33a and is supported on the base 36 via the shaft member 33e of the shaft support portion 33b. As a result, as shown in FIG. 7(a), a gap d can be maintained between the base 36 and the grip portion 33a even in the first position, allowing for smooth operation when lifting the grip portion 33a and rotating it to the second position. Additionally, the shaft support portion 33b of the lever member 33 is positioned in the lever notch 31g, a portion of which is located outside the interior facing surface 15g of the left vertical stile 15. This reduces the protruding dimension of the lever member 33 from the left vertical stile 15 when the lever member 33 is in the first position. Therefore, for example, when a building material unit is manufactured in a factory by attaching the fittings to the wall panels of a house in advance, the packaging size can be reduced. That is, if the protruding dimension of the lever member 33 is large when the fittings are attached to the wall panels, the packaging size will be increased by the size of the lever member 33. This raises concerns about problems such as reduced loading efficiency when transporting the building material unit by truck or other transportation means. However, with the fittings described above, the protruding dimension of the lever member 33 can be reduced, making it possible to reduce the packaging size.

[0023] In the above-described embodiment, the lock operating device is applied to a casement window, but it can also be applied to fixtures other than casement windows as long as the shoji screen is attached to a frame so that it can be opened and closed. Also, while the lock operating device is attached to the left vertical frame of the shoji screen, it may be attached to another frame material, or even to the frame material of the frame. Furthermore, the lock device to be operated is not limited to that described in the embodiment, and may be any device that locks and unlocks in response to the rotation of a lever member. In this case, the lever member does not necessarily need to be in a locked state when it is in the first position, but may be in a locked state when it is in the second position.

[0024] In addition, in the above-described embodiment, when the lock operating device is installed on a frame material, an operating unit is provided on the base, so there is no need to provide a separate handle for opening and closing operations, but it is not necessarily necessary to provide an operating unit on the lock operating device.

[0025] As described above, the lock operating device for building materials of the present invention comprises a base attached to the interior facing surface of a shaped member that constitutes a shoji screen or frame body, a lever member rotatably supported on the base via an axis member in the facing direction interposed between the base and the lever member, and an output unit connected to the lever member.The lock operating device for building materials operates by rotating the lever member around the axis of the axis member relative to the base, thereby locking and unlocking the locking device between the frame body and the shoji screen.The lever member has an axis support portion that protrudes to one side from the tip of the handle, and the axis member is provided on the axis support portion.The lever member is rotatably supported on the base with at least a portion of the axis support portion positioned outside the interior facing surface of the shaped member. According to this invention, the tip of the grip has a shaft support part that protrudes to one side, and the lever member is supported on the base via this shaft support part, so even when the grip is in a position along the find surface, it is possible to provide a gap between the grip and the find surface, preventing a situation in which operability is impaired from this position. Moreover, because the shaft support part is positioned on the outside of the interior find surface of the extrusion, the lever member is supported on the base, making it possible to reduce the protrusion dimension from the extrusion.

[0026] The present invention is also characterized in that, in the above-mentioned lock operating device for building materials, the handle portion extends in a straight line, and the locking device is in a locked state when the base end of the handle portion is facing downward and positioned along the interior viewing surface of the profile in a first position, and the locking device is in an unlocked state when the other end of the handle portion is in a second position protruding toward the room. According to this invention, it is possible to reduce the protruding dimension from the profile when the locking device is in the locked state compared to when it is in the unlocked state.

[0027] The present invention is also characterized in that, in the above-mentioned lock operating device for building materials, a notch is provided on the interior facing surface of the profile, and the lever member is supported with a portion of the shaft support portion positioned inside the notch. According to this invention, it is possible to further reduce the protruding dimension from the profile.

[0028] The present invention is also characterized in that, in the above-mentioned lock operating device for building fixtures, the output section is provided with an arm member that extends radially around the shaft member and rotates together with the shaft member, the extended end of the arm member is rotatably connected to the operated member of the locking device, and the locking device is locked and unlocked by the reciprocating movement of the operated member along a linear direction as the arm member rotates.
