Description

Technical Field

[0001] The present invention relates to the technical field of hardware components, and particularly to the operating mechanism of a locking device and a hardware.

Background Art

[0002] As shown in FIGS. 1 to 5, a conventional fitting includes a fitting frame 1 and a shoji 2. The fitting frame 1 includes four frames, namely, an upper frame 11, a lower frame 12, and a pair of vertical frames 13. The pair of vertical frames 13 connect the upper frame 11 and the lower frame 12, and a structure having an opening is formed by surrounding the upper frame 11, the lower frame 12, and the pair of vertical frames 13. The shoji 2 includes four frames, namely, an upper frame 21, a lower frame 22, and a pair of vertical frames 23. The pair of vertical frames 23 connect the upper frame 21 and the lower frame 22, and a face material 24 is provided between the pair of vertical frames 23. When the shoji 2 is disposed inside the fitting frame 1, it can close the opening of the fitting frame 1. One of the vertical frames 23 of the shoji 2 and one of the vertical frames 13 of the fitting frame 1 are connected via a hinge. The other vertical frame 23 of the shoji 2 is not hinge-connected to the other vertical frame 13 of the fitting frame 1. The outer peripheral side surface of the other vertical frame 23 of the shoji 2, which is disposed opposite to the other vertical frame 13 of the fitting frame 1, is a prospective surface 25, and the inner peripheral side surface of the other vertical frame 23 of the shoji 2 is a frame mounting surface 26. The engaging member 4 is slidably disposed on the prospective surface 25 of the other vertical frame 23 of the shoji 2, and by sliding with respect to the other vertical frame 23 of the shoji 2, it switches between an engaged state and a disengaged state with respect to the fitting frame 1. A pair of sliding guide members 27 are provided on the prospective surface 25 of the other vertical frame 23 of the shoji 2, and each sliding guide member 27 is installed along the longitudinal direction of the other vertical frame 23 of the shoji 2. A mounting hole 28 penetrating to the frame mounting surface 26 of the other vertical frame 23 is further provided on the prospective surface 25 of the other vertical frame 23 of the shoji 2. The engaging member 4 includes a lock bar 41 and a lock pin 42 installed on the lock bar 41. The lock pin 42 can abut against the lock receiving portion 14 of the fitting frame 1. Two bar side surface portions in the width direction of the lock bar 41 are respectively inserted into the pair of sliding guide members 27. A bar portion receiving hole 43 is provided in the lock bar 41, and the length of the bar portion receiving hole 43 is shorter than the length of the mounting hole 28.The operating mechanism 5 controls the position of the lock bar 41 with respect to the other vertical stile 23 of the shoji 2. The operating mechanism 5 includes an operating unit case 51 attached to the stile mounting surface 26 of the other vertical stile 23. A transmission member is provided inside the operating unit case 51. The drive end of the transmission member is a fitting hole 52 for attaching the drive shaft of the operation handle 6. A transmission plate 53 is provided at the output end of the transmission member. The transmission plate 53 sequentially penetrates through the mounting hole 28 and the bar receiving hole 43 and engages with the bar receiving hole 43. Since the axial direction of the fitting hole 52 of the transmission member is parallel to the indoor side surface of the facing material 24 of the shoji 2, when the conventional furniture is opened, the operation handle 6 is located in a plane perpendicular to the indoor side surface of the facing material 24. Since such an operation handle 6 is an out-of-plane handle, when opening and closing the furniture while pulling the operation handle 6, the moving direction of the shoji 2 and the axial direction of the operation handle 6 are the same direction, which makes it difficult for the user to pull the operation handle 6. Moreover, when closing and locking the shoji 2, since it is necessary to rotate the operation handle 6 in the opening direction of the shoji 2, the shoji 2 is likely to open slightly, and the situation of locking failure is induced because the lock pin 42 is not engaged with the lock receiving portion 14 of the furniture frame 1.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide an operating mechanism and furniture of a locking device that can easily pull an operation handle and avoid locking failure in order to solve the above-mentioned problems existing in the prior art.

Means for Solving the Problems

[0004] To solve the above technical problems, the present invention provides an operating mechanism for a locking device. The locking device includes an engaging member, an operating mechanism, and an operating handle. The engaging member is slidably installed on the prospective surface of the vertical frame of the shoji screen. By sliding relative to the vertical frame of the shoji screen, the engaging state and the non-engaging state with respect to the fitting frame are switched. A mounting hole is provided on the prospective surface on the outer peripheral side of the vertical frame of the shoji screen, and the mounting hole penetrates to the frame mounting surface on the inner peripheral side of the vertical frame of the shoji screen. The operating mechanism includes a transmission member. A fitting hole into which the drive shaft of the operating handle is inserted is provided at the drive end of the transmission member. The axial direction of the fitting hole is perpendicular to the indoor side surface of the facing material attached to the vertical frame of the shoji screen. An operating member is provided at the output end of the transmission member. The operating member passes through the mounting hole of the vertical frame of the shoji screen and is connected to the engaging member. When the operating handle rotates, the drive shaft of the operating handle drives the transmission member, and the transmission member slides the engaging member via the operating member.

[0005] If the axial direction of the fitting hole is perpendicular to the indoor side surface of the facing material attached to the vertical frame of the shoji screen, the operating handle attached to the fitting hole can always be positioned in a plane parallel to the indoor side surface of the facing material during rotation. Such an operating handle is an in-plane handle. In the process of performing a locking operation by rotating the in-plane handle, since the shoji screen is not pushed outward, it is difficult to cause a locking error. Also, when the in-plane handle is rotated, it is easy to unlock. The user can easily grasp the in-plane handle to close the fitting, and when closing the fitting, it is possible to avoid the situation where the user's hand slips off the in-plane handle.

[0006] Preferably, the transmission member includes a unit case, a driving member, and a driven member. The unit case is attached to the frame mounting surface of the vertical frame of the shoji screen. Inside the unit case, a driving support groove and a driven guide groove that communicate with each other are provided. The driving member is installed in the driving support groove and is rotatable in the driving support groove. The fitting hole is installed in the driving member. The driven member is installed in the driven guide groove. The operating member is inserted into the unit case and connected to the driven member. The driving member moves the driven member vertically along the driven guide groove. The rotational movement of the operation handle is converted into the vertical movement of the driven member by the driving member, with a simple structure and easy transmission.

[0007] Furthermore, the unit case includes a fixed case portion and a handle mounting case portion that are connected to each other. The fixed case portion is attached to the frame mounting surface of the vertical frame of the shoji screen. The handle mounting case portion is bent and installed with respect to the fixed case portion. The driving member is located in the handle mounting case portion. The handle mounting case portion is installed on the side of the fixed case portion closer to the facing material or on the side of the fixed case portion farther from the facing material. When the handle mounting case portion is installed on the side of the fixed case portion closer to the facing material, the area where the operation handle protrudes from the shoji screen can be reduced. When the handle mounting case portion is installed on the side of the fixed case portion farther from the facing material, it is easy to insert a sealant nozzle into the space between the handle mounting case portion and the facing material, facilitating the operation of injecting a sealant between the facing material and the vertical frame of the shoji screen.

[0008] Furthermore, a flange is provided at the connection location between the fixed case portion and the handle mounting case portion. The flange extends in a direction away from the handle mounting case portion. The installation of the flange can enhance the structural strength of the unit case.

[0009] Furthermore, when the handle mounting case portion is installed on the side of the fixed case portion closer to the facing material, the passive guide groove is a bending groove, and the bending groove includes a first groove portion installed on the fixed case portion and a second groove portion installed on the handle mounting case portion and bent with respect to the first groove portion. The passive member is a bending plate corresponding to the structure of the bending groove, and the bending plate includes a first plate material inserted into the first groove portion and a second plate material inserted into the second groove portion. The first plate material is connected to the operating member, and the driving member moves the second plate material. With this structure, the passive member can be stably installed in the passive guide groove, and the driving member can easily move the operating member via the passive member.

[0010] Furthermore, an observation hole is provided in the handle mounting case portion, and the position of the driving member can be viewed through the observation hole. The user can view the position of the driving member through the observation hole and can quickly adjust the driving member to the accurate mounting position.

[0011] Furthermore, a driving teeth portion is provided on the outer surface of the driving member, and a passive teeth portion meshing with the driving teeth portion is provided on the passive member. Since the driving teeth portion and the passive teeth portion mesh with each other, the driving member can easily move the passive member.

[0012] Furthermore, the driving member includes a driving body and a convex portion installed on the side of the driving body away from the facing material. The convex portion is installed in the driving support groove and is rotatable in the driving support groove. The driving body is located in the passive guide groove, the fitting hole is installed in the convex portion, and the driving teeth portion is installed on the driving body. With this structure, the structure of the unit case is made compact, and the operation handle can easily rotate the driving member.

[0013] Preferably, the engaging member includes a lock bar, the lock bar is installed on the prospective surface of the vertical frame of the shoji, the lock bar is provided with a bar portion receiving hole, the length of the bar portion receiving hole is shorter than the length of the mounting hole, and the operating member engages within the bar portion receiving hole. The operating mechanism of the locking device can be easily connected to the engaging member of the conventional locking device.

[0014] The present invention further relates to a fitting, including a fitting frame and a shoji, wherein an engaging member of a locking device is provided on the vertical frame of the shoji, and the operating mechanism of the locking device is connected to the engaging member of the locking device.

Advantages of the Invention

[0015] The operating mechanism of the locking device and the fitting of the present invention have the beneficial effect that the operating handle attached to the operating mechanism of the locking device of the present invention is a in-plane handle, so that the fitting can be easily opened and closed, locking errors are less likely to occur, and the convenience of operating the fitting is enhanced.

Also, terms such as "upper", "lower", "left", "right", "middle", and "one" used in this specification are only used to clarify the description and do not limit the scope in which the present invention can be implemented. Any change or adjustment of their relative relationship is regarded as within the scope in which the present invention can be implemented as long as it does not substantially change the technical content.

[0019] Example 1 As shown in FIGS. 6 to 12, regarding the operating mechanism 200 of the locking device of this example, the locking device includes an engaging member 100, an operating mechanism 200, and an operation handle 300. The engaging member 100 is slidably installed on the prospective surface 411 of the vertical frame 410 of the shoji 400, and by sliding with respect to the vertical frame 410 of the shoji 400, it switches between an engaged state and a non-engaged state with respect to the fitting frame 500. A mounting hole 412 is provided on the prospective surface 411 on the outer peripheral side of the vertical frame 410 of the shoji 400. The mounting hole 412 penetrates to the frame mounting surface 413 on the inner peripheral side of the vertical frame 410 of the shoji 400. The operating mechanism 200 includes a transmission member 210. A fitting hole 211 into which the drive shaft 310 of the operation handle 300 is inserted is provided at the drive end of the transmission member 210. The axial direction of the fitting hole 211 is perpendicular to the indoor side surface 421 of the facing material 420 attached to the vertical frame 410 of the shoji 400. An operating member 220 is provided at the output end of the transmission member 210. The operating member 220 passes through the mounting hole 412 of the vertical frame 410 of the shoji 400 and is connected to the engaging member 100. When the operation handle 300 rotates, the drive shaft 310 of the operation handle 300 drives the transmission member 210, and the transmission member 210 slides the engaging member 100 via the operating member 220.

[0020] If the axial direction of the fitting hole 211 is perpendicular to the indoor side surface 421 of the facing material 420 attached to the vertical frame 410 of the shoji 400, the operation handle 300 attached to the fitting hole 211 can always be positioned in a plane parallel to the indoor side surface 421 of the facing material 420 during rotation. Such an operation handle 300 is an in-plane handle. In the process of performing a locking operation by rotating the in-plane handle, since the shoji 400 is not pushed outward, the situation of locking failure is less likely to occur. When the in-plane handle is rotated, unlocking can be easily performed. The user can easily hold the in-plane handle to close the fixture, and when closing the fixture, the situation where the user's hand slips off the in-plane handle can be avoided.

[0021] As shown in FIGS. 12 to 18, the transmission member 210 includes a unit case 212, a driving member 213, and a driven member 214. The unit case 212 is attached to the frame mounting surface 413 of the vertical frame 410 of the shoji 400. Inside the unit case 212, a driving support groove 2121 and a driven guide groove 2122 that communicate with each other are provided. The driving member 213 is installed in the driving support groove 2121 and is rotatable in the driving support groove 2121, and the fitting hole 211 is installed in the driving member 213. The driven member 214 is installed in the driven guide groove 2122, and the operating member 220 is inserted into the unit case 212 and connected to the driven member 214. The driving member 213 moves the driven member 214 along the vertical direction in the driven guide groove 2122. The rotational movement of the operation handle 300 is converted by the driving member 213 into the vertical movement of the driven member 214, with a simple structure and easy transmission.

[0022] The unit case 212 includes a fixed case portion 2123 and a handle mounting case portion 2124 that are connected to each other. The fixed case portion 2123 is attached to the frame mounting surface 413 of the vertical frame 410 of the shoji 400, and the handle mounting case portion 2124 is bent and installed with respect to the fixed case portion 2123. The driving member 213 is located inside the handle mounting case portion 2124, and the handle mounting case portion 2124 is installed on the side of the fixed case portion 2123 closer to the facing material 420. When the handle mounting case portion 2124 is installed on the side of the fixed case portion 2123 closer to the facing material 420, the region where the operation handle 300 protrudes from the shoji 400 can be reduced. In this embodiment, as shown in FIG. 23, if the included angle between the fixed case portion 2123 and the handle mounting case portion 2124 is 90 degrees, the unit case 212 has an L-shaped structure. Thereby, the structure of the unit case 212 can be made more compact. In this embodiment, the facing material 420 is a glass panel, an acrylic panel, or the like.

[0023] As shown in FIGS. 10, 12 to 20, the frame mounting surface 413 of the vertical frame 410 of the conventional shoji screen 400 has a mounting hole 412 and a mounting hole 414. When comparing the mounting hole 412 and the mounting hole 414, the mounting hole 412 is closer to the indoor side. When the handle mounting case portion 2124 is installed on the side of the fixed case portion 2123 closer to the facing material 420, since the passive guide groove 2122 needs to conform to the structure of the unit case 212, the passive guide groove 2122 is a bent groove. The bent groove includes a first groove portion 2122A and a second groove portion 2122B. The first groove portion 2122A is installed in the fixed case portion 2123. The second groove portion 2122B is installed in the handle mounting case portion 2124 and is installed to be bent with respect to the first groove portion 2122A. The passive member 214 is a bent plate corresponding to the structure of the bent groove. The bent plate includes a first plate member 2141 inserted into the first groove portion 2122A and a second plate member 2142 inserted into the second groove portion 2122B. The first plate member 2141 is connected to the operating member 220, and the driving member 213 moves the second plate member 2142. With this structure, the passive member 214 can be adapted to the structure of the passive guide groove 2122, the passive member 214 is stably installed in the passive guide groove 2122, and the driving member 213 can easily move the operating member 220 via the passive member 214.

[0024] The handle mounting case portion 2124 has a handle mounting surface 2124B. The handle mounting surface 2124B is provided with two observation holes 2124A, a through hole 2124C through which the drive shaft 310 of the operation handle 300 passes, and a handle fixing hole 2124D. Through the observation hole 2124A, the position of the driving member 213 can be seen. The through hole 2124C and the fitting hole 211 are coaxially installed, making it easier to insert the drive shaft 310 of the operation handle 300. The outer case 320 of the operation handle 300 is connected to the handle fixing hole 2124D via a fastening member, and the fastening member is a screw. In this embodiment, the two observation holes 2124A are respectively located directly above and directly below the through hole 2124C, so that the user can see the position of the driving member 213 through the observation hole 2124A, and it is easier to quickly adjust the driving member 213 to the correct mounting position.

[0025] In order to facilitate the attachment and detachment of the transmission member 210, a removable inner plate 2126 is provided on the side of the fixed case portion 2123 facing the frame mounting surface 413 of the vertical frame 410 of the shoji 400. The inner plate 2126 and the fixed case portion 2123 are connected by screws 600. When the inner plate 2126 is removed, the drive member 213 and the driven member 214 can be directly taken out from the unit case 212.

[0026] On the side surface of the fixed case portion 2123 facing the inner plate 2126, a case portion fixing hole 2123A is provided. The operating mechanism 200 of the locking device further includes an intermediate connection plate 215. The intermediate connection plate 215 is provided with a frame connection hole 2151 corresponding to the mounting hole 414 and a case connection hole 2152 corresponding to the case portion fixing hole 2123A. The screw 600 passes through the frame connection hole 2151 and the mounting hole 414 to connect the intermediate connection plate 215 and the vertical frame 410 of the shoji 400. The screw 600 passes through the case portion fixing hole 2123A and the case connection hole 2152 to connect the intermediate connection plate 215 and the fixed case portion 2123.

[0027] A drive tooth portion 2131 is provided on the outer surface of the drive member 213, and a driven tooth portion 2143 meshing with the drive tooth portion 2131 is provided on the driven member 214. By meshing the drive tooth portion 2131 and the driven tooth portion 2143, it becomes easier for the drive member 213 to move the driven member 214.

[0028] The drive member 213 includes a drive main body 2132 and a convex portion 2133 provided on the side of the drive main body 2132 away from the facing material 420. The convex portion 2133 is installed in the drive support groove 2121 and is rotatable in the drive support groove 2121. The drive main body 2132 is located in the driven guide groove 2122. The fitting hole 211 is installed in the convex portion 2133, and the drive tooth portion 2131 is installed in the drive main body 2132. The drive main body 2132 is a gear, and the portion of the driven member 214 corresponding to the gear of the drive main body 2132 is a rack. This structure makes the structure of the unit case 212 compact, easy to transmit power, and helps the operation handle 300 to rotate the drive member 213.

[0029] The method by which the driving member 213 moves the driven member 214 is not limited to the structure in which the gear and the rack are interlocked, and any other structure in which the driving member 213 moves the driven member 214 can be realized by using a connecting rod or the like.

[0030] In this embodiment, the driving support groove 2121 is located on the groove wall surface of the second groove portion 2122B away from the facing material 420. The driving support groove 2121 is provided with a communication port 2121A communicating with the first groove portion 2122A. The communication port 2121A can penetrate the convex portion 2133, and the driving body 2132 is located in the second groove portion 2122B. After removing the inner plate 2126, the driven member 214 can be taken out from the unit case 212. The convex portion 2133 can be taken out from the unit case 212 together with the driving body 2132 after passing through the communication port and the first groove portion 2122A. This structure is convenient for removing the driving member 213.

[0031] As shown in FIG. 9, the engaging member 100 includes a lock bar 110 and a lock pin 120 installed on the lock bar 110. The lock pin 120 can be in contact with the lock receiving portion of the fitting frame 500. The lock bar 110 is installed on the prospective surface 411 of the vertical frame 410 of the shoji 400. The lock bar 110 is provided with a bar portion receiving hole 111. The length of the bar portion receiving hole 111 is shorter than the length of the mounting hole 412. The operating member 220 is engaged in the bar portion receiving hole 111. The operating mechanism 200 of the locking device can be easily connected to the engaging member 100 of the locking device in the prior art.

[0032] This embodiment further relates to a fitting, which includes a fitting frame 500 and a shoji screen 400. The fitting frame 500 includes an upper frame 520, a lower frame 530, and a pair of vertical frames 510. The pair of vertical frames 510 connect the upper frame 520 and the lower frame 530, and a structure with an opening is formed by surrounding the upper frame 520, the lower frame 530, and the pair of vertical frames 510. The shoji screen 400 includes an upper frame 430, a lower frame 440, and a pair of vertical frames 410. The pair of vertical frames 410 connect the upper frame 430 and the lower frame 440, and a facing material 420 is provided between the pair of vertical frames 410. When the shoji screen 400 is disposed inside the fitting frame 500, it can close the opening of the fitting frame 500. One of the vertical frames 410 of the shoji screen 400 and one of the vertical frames 510 are connected via a hinge. An engaging member 100 of a locking device is provided on the other vertical frame 410 of the shoji screen 400 that is not hinge-connected to the vertical frame, and an operating mechanism 200 of the locking device of this embodiment is connected to the engaging member 100 of the locking device.

[0033] As shown in FIGS. 6, 8, 21, and 22, since the operation handle 300 attached to the operating mechanism 200 of the locking device of the present invention is an in-plane handle, the in-plane handle can be selected and attached from an antibacterial type in-plane handle, a removable type in-plane handle, an in-plane handle having a locking member 700, etc., and the operation handle 300 can be changed to various types as needed. The in-plane handle of this embodiment selects an in-plane handle having a locking member 700.

[0034] The operating mechanism 200 of the locking device of the present invention can be directly attached to the vertical frame 410 of the shoji screen 400 to which a conventional out-of-plane handle is attached, and an in-plane handle can be attached to the operating mechanism 200. Thus, without replacing the shoji screen 400, the out-of-plane handle can be uniformly replaced with an in-plane handle.

[0035] Example 2 As shown in FIG. 24, the difference between this embodiment and Embodiment 1 is that the handle attachment case portion 2124 is installed on the side of the fixed case portion 2123 that is away from the facing material 420. When the handle attachment case portion 2124 is installed on the side of the fixed case portion 2123 that is away from the facing material 420, the sealant nozzle 800 can be inserted into the space between the handle attachment case portion 2124 and the facing material 420, making it easier to perform the operation of injecting the sealant between the facing material 420 and the vertical frame 410 of the shoji 400.

[0036] Embodiment 3 As shown in FIG. 25, the difference between this embodiment and Embodiment 1 is that a flange 2125 is provided at the connection portion between the fixed case portion 2123 and the handle attachment case portion 2124, and the flange 2125 extends in a direction away from the handle attachment case portion 2124. In this embodiment, the included angle between the flange 2125 and the handle attachment case portion 2124 is 90 degrees, the flange 2125 and the fixed case portion 2123 are located on the same straight line, and when the unit case 212 forms a T-shaped structure, the installation of the flange 2125 can enhance the structural strength of the unit case 212.

[0037] Since the operation handle 300 attached to the operation mechanism 200 of the locking device of the present invention is a in-plane handle, the furniture can be easily opened and closed, the situation of locking errors is less likely to occur, and the convenience of operating the furniture is improved.

[0038] As described above, the present invention effectively overcomes various drawbacks in the prior art and has high industrial utility value.

[0039] The above embodiments are only illustrative explanations of the principle and effects of the present invention and do not limit the present invention. Those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention.
