PROBLEM TO BE SOLVED: To develop an electric lock which can be mounted without exchanging an existent door or applying reprocessing to the door.SOLUTION: A mechanism accommodation section 37 of a lock case 30 is formed by combining a large rectangular main body part 50 and a small rectangular protruding part 51. The protruding part 51 of the lock case 30 is firstly inserted into an insertion opening 23. A root portion 62 of the protruding part 51 is then located in the vicinity of a lower-side point 80 of the insertion opening 23, and an upper side of the lock case 30 is rotated largely like an arrow around the root portion 62 of the protruding part 51. A point 63 of the lock case passes through an upper-side point 81 of the insertion opening 23 and the main body part 50 enters a cavity part 22 for key accommodation.

PROBLEM TO BE SOLVED: To provide a bicycle parking device that houses a bicycle in an upper space, has high safety, and can be easily operated.SOLUTION: A mounting member 16 for mounting a bicycle 50 is swingably installed in a bearing member 1 erected on a floor surface. A connection plate 3 fixed to the bearing member 1 and a guide member 4 fixed to the mounting member 16 are connected by a rocking shaft 12. The bearing member 1 is provided with a lock member 15. The lock member 15 is provided with a contact part 20a, a contact part 20c, and a slide part 20b. The guide member 4 is provided with a long hole 36. A lock pin 7 engages with the long hole 36 and the lock member 15. When the lock pin 7 moves inside the long hole 36 and engages with the contact part 20a or the contact part 20c, the mounting member 16 is disabled from rocking in a state of keeping a horizontal position or an inclined position. When the lock pin 7 is contacting with the slide part 20b, the mounting member 16 is smoothly swingable.

PROBLEM TO BE SOLVED: To provide an auxiliary member for easily determining a position of a door handle attachment seat.SOLUTION: A handle attachment seat 23b is disposed on one of front and back sides of a door 15 in which a lock 19 is disposed, and a positioning member 1 is disposed in a fitted state on the other attachment seat 23a. In that state, a square core 33 communicates with the attachment seats 23, the door 15 and the lock 19, and the handle attachment seats 23 are fixed. Subsequently, the positioning member 1 is detached and a handle 28 for the door is fixed. The positioning member 1 comprises a through-hole 2, a square core holding portion 3, and a fitting portion 5 for being fitted into a hole 25 of the handle attachment seat 23a. When the positioning member 1 is fitted into the hole 25 of the handle attachment seat 23a, the shaft center of the square core holding portion 3 agrees with that of a square core attachment portion 30 when the handle 28 for the door is attached to the handle attachment seats 23.

PROBLEM TO BE SOLVED: To provide a square core fixing structure and a door handlebar, which are capable of eliminating connecting means such as screws, of surely fixing the square core in a hub of a lock case without labor, and of reducing labor for fixing the door handlebar.SOLUTION: A door handlebar includes a pair of handlebars 2, 3 provided on both sides of a door respectively so as to sandwich the door and a square core 5 inserted into a hub square hole 47 of a hub provided in a lock case 50. The square core 5 has a groove part in which an elastic member 6 is disposed, and the elastic member 6 disposed in the groove part has an exposed part 70, which is exposed from the groove part, formed in a position at least on one side of the square core 5. Thus, when the square core 5 is inserted in the handlebar 2, the exposed part 70 is pressed in a direction in which the exposed part 70 comes into the groove part by a through-hole 31 of the handlebar 2, and a square hole pressing force exposed part 73 of the elastic member 6 located at the middle of the square core 5 is deformed or displaced in a direction in which it is exposed in regard to the groove part to press the inner wall of the hub square hole 47.

PROBLEM TO BE SOLVED: To provide a hook lock usable for both a sliding door and a hinged door and easily designable for installation. SOLUTION: This hook lock 1 includes a case 2, a hook piece 3, a trigger 7, a trigger support member 8, a spring 9, a link member 10, a lever member 11, an attitude support member 12, a slider 13, and a lock part 53. The hook lock 1 links the members so that the hook piece 3 projects from the case 2 when the trigger 7 retreats to the case 2, has an area in which the trigger 7 can retreat and project independently, and has a time before the movement of the trigger 7 is interlocked with the movement of the hook piece 3. Since the hook piece 3 requires a time before projection, the design of the peripheral members can be facilitated when the hook lock is used for a hinged door (wing door). Consequently, the hook lock is used for the hinged door. COPYRIGHT: (C)2011,JPO&INPIT
