[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to various handles, such as a handle of an umbrella and a handle of a bicycle, and aims to provide a novel handle with a lock particularly useful for preventing theft and a bendable rod used for the handle. .

[0002]

[Prior art]

 Despite the fact that Japan is highly regarded as a safe nation with a high level of security among the rule-of-law nations, accidental theft of umbrellas and bicycles by inexperienced people is still unending on a daily basis. Various proposals have been made to prevent the crime by using chains and breaks. For example, the umbrella is held like an "umbrella with a key" described in Japanese Utility Model Laid-Open No. 6-38630. A lock is installed at the end of the part, a universal lock is attached, and the universal lock is hooked on a frame such as an umbrella stand, and the universal lock is set in the hole of the dial lock to lock. The lock body is attached to the bicycle frame, as in the “Anti-theft device for bicycles” described in the official gazette, and a chain is used as the lock. Returned to be locked by the lock body, or disclosed in Japanese Utility Model Application Laid-Open No. 6-12991 as "a small portable anti-theft device so that it can be used to prevent theft of various protected objects. Wa The wire is pulled out of the main body case when the locking member is pulled, the wire is wound around the protected object, and it can be locked using a separately prepared lock. There is.

[0003]

[Problems to be solved by the invention]

 However, among those already proposed above, the “umbrella for theft prevention with key” disclosed in Japanese Utility Model Laid-Open Publication No. Hei 6-38630 can be applied only to umbrellas, and the wire becomes an obstacle during use. However, it is relatively fragile compared to other security devices, and the "bicycle theft prevention device" disclosed in Japanese Utility Model Laid-Open Publication No. 5-69719 is good to attach the wire itself to the bicycle, There is a problem that it is obstructive because there is no place to store the wire, and in the case of the “small portable anti-theft device” disclosed in Japanese Utility Model Application Laid-Open No. 6-12991, a key is not attached to the main body. You have to carry it with you, and it will be useless without a separately prepared key.In addition, it is fragile because the internal structure is confidential, and the wire must be small enough to be wound and stored. And it has become a thing easy to cut me, challenge, etc. where there is anxiety on crime prevention has been left.

[0004]

[Means for Solving the Problems]

 Unlike the conventional ones, this device can be used as a handle when it is in a fixed state, does not require any obstructive wires or other components, and is optional when it is in a broken state. A lock handle for umbrellas and other devices that has a security effect by adopting the following configuration so that the main body can be moved and locked around any rod-shaped object. Is realized.

[0005] It is composed of a plurality of unit pieces, each having a thickness suitable for being gripped by hand and formed of a hollow short cylinder body having stacking projections formed at both ends, which are adjacent and connected on substantially the same axis. In this case, in any case, the adjacent unit pieces each have a stacking protruding piece having a screw hole for connection, and a stacking protruding piece having a sliding long hole of the adjacent unit piece. In the overlapping state, the screws are loosely fitted into both holes and screwed together, and the stacking protruding pieces are placed on the same side every other overlapping state. At the same time, by using a connecting structure in which the entire body is urged in the contraction direction by an elastic body inserted so as to make them penetrate, only bending in the direction following the relative stacking protruding piece surface is achieved. It is formed into a bendable rod and has a connection screw hole in the unit body at both ends of the bendable rod. The unit piece side with the stacking protrusion left is attached to the lower end of the umbrella shank and integrated, while the unit piece side with the sliding hole with the stacking piece left has the lower end of the umbrella shank. The umbrella and other handle with a lock are configured to incorporate a lock mechanism that can be unlocked between them.

The lock mechanism in the handle with a lock may be, for example, a dial lock. The dial lock body is positioned at the lower end of the shank of the umbrella and immediately above the bendable rod mounting portion. Are substantially perpendicular to the shaft center of the shank and are oriented so as to be oriented in the bending direction of the bendable rod, while the unit piece at the free end of the bendable rod has an elongated hole for the slide. It is possible to employ a key having a key portion which is made to be able to enter and exit freely by using a knob which guides the key.

In order to realize the handle with a lock for an umbrella or the like of the present invention, each end of the hollow short tube main body having a thickness suitable for grasping by hand is formed in a relative shape. After forming the stacking protruding piece, the connecting screw hole is located at the center of the stacking protruding piece at one end near the tip, and the stacking protruding piece at the other end side. In the center near the tip of the projecting piece, a long slot for sliding extending to the middle of the hollow short cylinder body is formed as a unit piece, and these unit pieces are adjacent and connected on substantially the same axis. In this case, in each case, the adjacent unit pieces overlap each other with the stacking protruding piece with the sliding screw hole for the adjacent unit piece, and the stacking protruding piece with the sliding long hole of the adjacent unit piece. In such a state, screws are loosely fitted into both holes and screwed, and the stacking protruding pieces overlap. The connection structure shall be such that every other unit is on the same side, and the connection structure shall be urged in the contraction direction by an elastic body inserted so that they are penetrated. Accordingly, it is effective to use a bendable rod formed so as to be able to bend only in a direction in accordance with the relative protruding piece surface for stacking.

In order to clarify the configuration of the present invention described above, in the following, representative examples of a handle with a lock for an umbrella or the like having the configuration of the present invention, and a bendable rod used therein will be described. An example will be described.
