Description

[Detailed description of the invention] The present invention relates to a locking device attached to an umbrella stand, and its feature is that the locking device is fixed to the rotor of the cylinder lock when the door-like closing arm closes. After the latching arm is converted to the latching system, the latching system is maintained and locked by removing the key, and on the other hand, the latching system is released by returning the latching arm using the key. In particular, the embodiments shown in the accompanying drawings will be described in detail below.

As shown in the figure, a door-shaped closing arm 2 is pivotally attached to the open opening of a substantially U-shaped main body 1 so that it can be opened and closed by a pin 3, and a spring 4 is provided so that it tends to open at all times. There is no difference in nature from this type of locking device for an umbrella stand in that a mounting tool 5 is provided on the back of the umbrella holder 1 to attach it to the umbrella stand base frame A.

In the present invention, the closing arm 2 in the main body 1 is
A cylinder lock 6 is fixed inside the protrusion on the side where the lock is not pivoted so that its key insertion hole is exposed at the upper end, and a rearward hooking part 8 is bent on the rotor 7 of the cylinder lock 6. The formed latch arm 9 is fixedly fixed forward and is always kept in a tendency to easily pivot toward the open mouth by the spring 10, and the lock arm 9 is close to the cylinder lock 6 and in front thereof hits the back of the latch part 8. The actuating arm 13, which has a forward-facing receiving surface 11 and a blocking surface 12, is pivoted by a pin 14 on the outside and is always kept in a tendency to easily pivot forward by the spring 10, so that in an open position without locking. As shown in FIGS. 1 to 3, while the latching arm 9 is turned outward against the spring 10, the latching portion 8 is received and stabilized by the blocking surface 12 of the operating arm 13. When the latching arm 9 is turned backward, the locking arm 9 is released from the restraint by the blocking surface 12 to allow the latching arm 9 to turn inward, and the latching arm 9 is separately attached to the tip of the closing arm 2. A receiving part 15 corresponding to the part 8 is provided so that the closing arm 2 can be opened after the handle part B of the umbrella is inserted into the U-shaped recess of the main body 1 for use from the open position as shown in FIGS. 1 to 3. By closing in the direction of the arrow,
The tip pushes the actuating arm 13 backward to release the locking part 8 from the blocking surface 12, and the locking arm 13 is rotated by the spring 10 as shown in FIG. After the latch part 8 is advanced to the front part of the lock 15, the latch arm 9 is firmly fixed in the advanced position by removing the key, and the closing arm 2 is held in the closed locking position. To unlock the lock, insert the key into the cylinder lock 6 and rotate the locking arm 9 outward together with the rotor 7 to release the restraint on the closing arm 2 and elastically open the closing arm 2 by the spring 4. That's how it happens.

It is preferable that a stopper 16 is protruded from the base end of the closing arm 2 to restrict the degree of opening.
It is preferable to form the base frame 6 in a C-shaped cross section and to use a shaped steel having a substantially C-shaped cross section, and to connect the main body 1 to this in a dovetail relationship with the fixture 5.

As explained above, according to the present invention, as the door-shaped closing arm closes, the latching arm provided on the cylinder lock can be converted to the latching system with the intervention of the operating arm. In addition, the lock can be locked while maintaining the locking system by removing the key, which not only has an extremely simple structure and is highly effective in preventing theft, but also allows the key to be compact. Therefore, it is convenient for the user to carry around, and if the operating arm is placed inward so that it overlaps with the latching arm, and the spring is provided in common for both arms, the equipment can be made compact and inexpensive. There are advantages to being able to do so.

Claims (1)

[Claims for Utility Model Registration] 1. A door-shaped closing arm 2 at the opening of the approximately U-shaped main body 1.
In addition to being pivoted so that it can be opened and closed, it is provided so that it tends to be opened at all times by the spring 4.
A cylinder lock 6 is fixed inside the protruding part of the main body 1 on the side to which the closing arm 2 is not pivoted so that the key insertion hole thereof is exposed at the upper end, and the rotor 7 of the cylinder lock 6 is fixed. A locking arm 9 with a locking portion 8 is provided with a spring so that it tends to be easily rotated toward the open mouth at all times, and a forward facing receiving surface 11 corresponding to the tip of the closing arm 2 is provided in the front near the cylinder lock 6. An actuating arm 13 having a blocking surface 12 is pivotally installed so that the blocking surface 12 can catch and restrain the locking portion 8 of the locking arm, and furthermore, the closing arm 2 has the locking portion 8 at the tip thereof. A receiving part 15 corresponding to the closing arm 2 is provided.
After releasing the engagement between the blocking surface 12 of the actuating arm 13 and the latching part 8, the receiving part 15 can be latched and restrained by the latching part 8. A locking device for an umbrella stand which can be locked by removing a key from a cylinder lock 6 in the construction mode. 2. The utility model according to claim 1, in which the actuating arm 13 is provided inwardly in a state where it overlaps with the latching arm 9, and both arms 13, 9 are associated with a common spring 10. Locking device for umbrella stand.
