Description

  The present invention relates to a thumb-turn holding mechanism used in a lock opening / closing device that automatically locks or unlocks a door by rotating a thumb turn, and particularly used in a lock opening / closing device that can be easily attached to a door later. It is related with the thumb turn clamping mechanism.

  There is an increasing need for a lock opening and closing device (electronic lock) that can automatically lock or unlock the door by rotating the thumb turn of the door. For example, when renting a rental property, a so-called preview (introspection) is performed in which a prospective customer is actually guided into a room. In order to perform a preview, it is necessary to borrow a key from the landlord of the property, and there is a problem that the procedure is very troublesome.

  However, it is not preferable in terms of security to copy the key or to hide the key near the property (for example, in a post or a machine room). Also, in the office, when a plurality of employees enter and leave, it is not preferable in terms of security to duplicate keys for the number of employees or to hide keys near the office.

  Further, in recent years, a service for matching a person who rents a room with a person who rents a room is provided in SNS (Social Networking Service) or the like. With this service, it is possible to lend and rent a room between individuals without going through a trader. For example, it is possible to lend a room to another person while away from home. However, also in this case, it is not preferable from the viewpoint of security to lend a home key to another person during absence.

  As described above, there is an increasing need for a lock opening / closing device capable of automatically locking or unlocking a door by remote operation. For example, a lock opening / closing device disclosed in Patent Document 1 has been proposed (for example, a patent Reference 1).

Therefore, as shown in FIGS. 9A to 9C, the second plate-like member 220 can operate along the longitudinal direction (second direction (Y direction)) of the long hole 223. .

  As described above, the first plate 200 is connected to the first plate-like member 210 that is operable in the first direction perpendicular to the longitudinal direction of the connecting member 100 and the first plate-like member 210. The second plate-shaped member 220 is operable in the second direction perpendicular to the longitudinal direction of the connecting member 100 and the first direction. For this reason, the rotation center (rotation axis) of the thumb turn S can coincide with the rotation (rotation axis) of the clamping mechanism 10 according to the present embodiment.

  As described above, the thumb-turn clamping mechanism 10 according to the embodiment is the thumb-turn S clamping mechanism 10 that is used in the lock opening / closing device 1 that rotates the thumb turn S to lock or unlock the door D. The clamping mechanism 10 is opposed to the connecting member 100 whose one end 101 side is connected to the lock opening and closing device 1, the first main surface 201 connected to the other end 102 side of the connecting member 100, and the first main surface 201. A first plate 200 having a second main surface 202; a columnar member 300 in which a spiral groove 301 is formed on the outer peripheral surface and rotatably held (clamped) on the second main surface 202 side; The surface has spiral grooves 401 and 501 that are screwed into the spiral groove 301 of the columnar member 300, and through holes 402 and 502 that penetrate in the thickness direction are formed, and the distance between the columns expands and contracts as the columnar member 300 rotates. And first and second clamping members 400 and 500 for clamping the thumb turn S.

  That is, by rotating the columnar member 300 that is rotatably held (clamped) on the second main surface 202 side of the first plate 200, the first plate 200 according to the type of the thumb turn S (thickness of the knob T). The distance between the second clamping members 400 and 500 can be adjusted. Therefore, the thumb T of the thumb turn S can be held regardless of the type of thumb turn S (thickness of the knob). Moreover, since the columnar member 300 is merely rotated, the thumb T knob T can be clamped by adjusting the distance between the first and second clamping members 400 and 500 with a simple operation. Further, since it is not necessary to check the type of thumb turn S, the burden on the user is reduced. Furthermore, since it is not necessary to prepare a mechanism for holding the thumb T of the plurality of thumb turns S according to the kind of the thumb turns S, the manufacturing cost can be reduced.

  That is, the first plate 200 is connected to the first plate member 210 operable in a first direction (X direction) perpendicular to the longitudinal direction of the connection member 100, and the first plate member 210. And a second plate-like member 220 operable in a second direction (Y direction) perpendicular to the longitudinal direction of the connecting member 100 and the first direction (X direction). For this reason, the rotation center (rotation axis) of the thumb turn S can coincide with the rotation center (rotation axis) of the clamping mechanism 10 according to the present embodiment. As a result, the rotation center (rotation axis) of the thumb turn S and the rotation center (rotation axis) of the pinching mechanism 10 according to the present embodiment do not coincide with each other, and a problem that the thumb turn S cannot be rotated can be suppressed. . In addition, when the thumb turn S is rotated, it is possible to suppress an excessive force from being applied to the clamping mechanism 10 of the thumb turn S. For this reason, it is possible to effectively suppress the failure of the holding mechanism 10 of the thumb turn S and the lock opening / closing device 1 including the holding mechanism 10 of the thumb turn S.

  Further, the first and second clamping members 400 and 500 of the clamping mechanism 10 according to the embodiment invention connect (engage) the extension claws 800 to the end surfaces 403 and 503 on the opposite side to the first plate 200, respectively. Can be extended.

  That is, since the first and second clamping members 400 and 500 that clamp the thumb T of the thumb turn S can be extended, the height of the thumb turn S is low, and only the first and second clamping members 400 and 500 are used. Even when the thumb T knob T cannot be securely clamped, the thumb nail T is firmly clamped by connecting (engaging) the extension pawl 800 and extending the first and second clamping members 400, 500. be able to.

  In addition, the clamping mechanism 10 according to the embodiment includes a second plate 600 disposed to oppose the second main surface 202 of the first plate 200, and the columnar member 300 includes the first and second plates. It is rotatably held (clamped) between 200 and 600.

  For this reason, since the columnar member is rotatably held (clamped) with a simple structure, it is possible to obtain a structure with few failures and reduced costs.

  Further, a through hole 601 that penetrates in the thickness direction of the first plate 200 or the second plate 600 of the thumb turn clamping mechanism 10 according to the embodiment and has a spiral groove formed on the inner peripheral surface, and screwed into the spiral groove The end portion 701T includes a bolt 701 that abuts the columnar member 300. By rotating the bolt 701, the force with which the end portion 701T of the bolt 701 presses the columnar member 300 is changed. A slidability adjusting mechanism 700 that changes the slidability is provided.

  That is, the plate 600 of the first plate or the second plate penetrates in the thickness direction and is screwed into the spiral groove with the through hole 601 having a spiral groove formed on the inner peripheral surface, and the end 701T is the columnar shape. Since the slidability adjusting mechanism (700) including the bolt 701 that contacts the member 300 is provided, by rotating the bolt 701, the first and second holding members 400, which hold the knob T of the thumb turn S, Since the force at the time of rotating the columnar member 300 for adjusting the distance between 500 can be adjusted, the convenience for the user is improved.

  As described above, the present invention can provide a thumb-turn holding mechanism that can hold the thumb-turn knob regardless of the type of thumb-turn.
