An adapter that converts the locking / unlocking method of a lock that operates by sliding up and down into a thumb turn method.

Abstract

To provide an adapter that converts the locking / unlocking operation method of a lock that is locked / unlocked by up / down sliding operation with low operability and visibility into a thumb turn type by attaching it to a door on which a combination lock or a door end lock is installed. [Solution] The base part 1 is attached to the frame of a door on which a combination lock or door end lock is installed, and by transmitting the rotation of the thumb turn part 2 to the slide part 3, it corresponds to a lock that is locked and unlocked by an up and down sliding operation. In addition, by attaching a smart lock for thumb turn to the thumb turn part 2, it becomes possible to lock and unlock using the smart lock system for thumb turn.

Description

[Technical Field]

[0001] This specification relates to an adapter that, when attached to a door equipped with a combination lock or door end lock, converts the locking / unlocking operation method of a lock that is operated by sliding up and down to a thumb turn type. [Background technology]

[0002] A combination lock is attached to a door that opens and closes by sliding it up and down, and can be unlocked and locked from the inside of the room. A door lock is a lock that is attached to a door that opens and closes by pulling it one way, and can be unlocked and locked by sliding it up and down from the inside of the room. A smart lock for thumb turns is a unit that is installed on a door that is systemized with a control circuit and mechanism to lock and unlock the door lock's thumb turn.

[0003] Patent Publication No. 2001-220930 Patent Publication No. 2022-172650 Patent Publication No. 2018-028261 Summary of the Invention [Problem to be solved by the invention]

[0004] Locks that are locked and unlocked by sliding up and down have poor operability and visibility when locking and unlocking.

[0005] Locks that are locked and unlocked by sliding up and down cannot be operated with a thumb-turn smart lock, and cannot be locked and unlocked using the thumb-turn smart lock system. [Means for solving the problem]

[0006] It consists of a base part 1 that is fixed to the door frame to fix the relative position of the combination lock or door end lock and this adapter, a thumb turn part 2 that can rotate the thumb turn-shaped operating part using a bearing provided in the base part 1, and a slide part 3 that slides in the Y-axis direction as the thumb turn part 2 rotates.

[0007] The base part 1 is fixed to the door frame by double-sided tape, adhesive, magnets or screws.

[0008] The thumb turn portion 2 has a rotation axis 4 inserted into the base portion 1, a rotation force transmission protrusion 5 that transmits rotation force to the slide portion 3, and a rotation operation receiving portion 6 that receives the thumb turn type rotation operation.

[0009] The base portion 1 has a rotary bearing portion 7 into which the rotary shaft 4 is inserted.

[0010] The slide portion 3 has a rotational force transmission recess 8 that receives force from the rotational force transmission protrusion 5, and a lock operation portion 9 that transmits force to the indoor operation portion of the lock that locks and unlocks by sliding up and down.

[0011] The rotary shaft 4 may be inserted into the rotary bearing portion 7 either directly or via a bearing.

[0012] When the rotation operation receiver 6 is rotated from inside the room, the rotational force transmitting convex portion 5 rotates around the rotation axis 4 and moves in the Y-axis direction. At this time, the rotational force transmitting convex portion 5 moves the rotational force transmitting concave portion 8 in the Y-axis direction, and the sliding portion 3 slides in the Y-axis direction. When the rotation operation receiver 6 is rotated in a range of 45 degrees or more and 135 degrees or less, the sliding portion 3 slides in the Y-axis direction in a range of 1 cm or more and 3 cm or less.

[0013] As described above, by transmitting the rotational force of the rotational operation receiving portion 6 and moving the lock operation portion 9 in the Y-axis direction, it is possible to lock and unlock the door by operating it up and down by sliding it from inside the room.

[0014] When the key is locked or unlocked from outside the room, the sliding portion 3 slides in the Y-axis direction, causing the rotational force transmitting recess 8 to also slide in the Y-axis direction. At this time, the rotational force transmitting recess 8 moves the rotational force transmitting protrusion 5 in the Y-axis direction, causing the rotational force transmitting protrusion 5 to rotate around the rotation axis 4. When the sliding portion 3 is slid within a range of 1 cm to 3 cm, the rotation operation receiver 6 rotates within a range of 45 degrees to 135 degrees.

[0015] As a result of the above, the movement of the lock operation part 9 in the Y-axis direction is transmitted to the rotation of the rotation operation receiving part 6.

[0016] In order to achieve smooth sliding in the Y-axis direction, or to prevent shaking in the X-axis direction, or to prevent shaking in the Z-axis direction, the movement of the slide portion 3 may be assisted by attaching a slide rail to the slide portion 3, or by attaching a bearing to the slide portion 3.

[0017] In order to achieve smooth sliding of the slide part 3 in the Y-axis direction, or to prevent wobbling in the X-axis direction, or to prevent wobbling in the Z-axis direction, the base part 1 may have a slide rail attached to it to assist the movement of the slide part 3, or a bearing may be attached to it to assist the movement of the slide part 3.

[0018] For smooth transmission of force between the rotational force transmitting protrusions 5 and the rotational force transmitting recesses 8, the force may be transmitted via bearings.

[0019] The lock operation unit 9 can be divided into an exchangeable sliding unit 10 and an exchangeable key operation unit 11 to accommodate various indoor operation units of up-and-down sliding locks. The exchangeable sliding unit 10 and the exchangeable key operation unit 11 can be fixed together using adhesive, screws, or double-sided tape.

[0020] In order to adjust the relative positions of the slide portion 3 and the base portion 1 in the X-axis direction, the slide portion 3 may be configured to be shifted toward the negative or positive X-axis direction.

[0021] A cover 12 may be attached to protect the internal structure of the adapter or to prevent materials, parts, dust, etc. unrelated to the operation of the adapter from getting caught in the thumb turn portion 2 or slide portion 3. [Effects of the Invention]

[0022] The locking and unlocking method of a crescent lock, which is independent of left / right orientation or size, can be converted to a thumb-turn type. Also, by installing a thumb-turn smart lock, it becomes possible to lock and unlock the crescent lock using the thumb-turn smart lock system. [Brief explanation of the drawings]
