2. Description of the Related Art A conventional locking device for an umbrella stand is shown in FIG.
As shown in FIG. 5, a concave portion b for accommodating an umbrella handle is provided on the front surface of the support member a, and a locking member c is pivotally attached to the front end portion of the support member a so as to be rotatable about a vertical axis. The ones that have been done are listed. In order to hold and lock the umbrella in the locking device for the umbrella stand having such a structure, first, the umbrella is arranged in the recess b, and then the locking member c is rotated from the unlocked position A to the locked position B and then locked. Then, the locking member c is fixed at the locking position B. In the locking device for an umbrella stand having such a configuration, it is difficult to perform the locking operation with one hand because it is necessary to rotate the locking member c while holding the umbrella in the recess.

In order to eliminate this inconvenience, as shown in FIG. 6, the locking member c is rotatably supported so as to be accommodated in the inside of the supporting member a from the side surface of the recess b when unlocked.
And an opening / closing button d is projected from the inner end of the recess b toward the front. In order to hold and lock the umbrella by the locking device for umbrella stand having such a structure, first, the umbrella is arranged in the concave portion b, and then the opening / closing button d is pushed by the umbrella to move the locking member c to the supporting member a. By advancing from the unlocking position A inside to the locking position B in the recess b through the side surface of the recess b, both side surfaces of the recess b are connected and locked by the locking member c. Since the locking can be performed only by pushing the opening / closing button d with the umbrella,
The locking work can be performed with one hand, which is extremely simple.

[0004]

However, the locking device for the umbrella stand having such a structure has a drawback that it is easily broken. That is, the support member a is provided with the opening e on the side surface of the concave portion on the side where the locking member c is projected and retracted so that the locking member c can be moved back and forth. In the conventional locking device for umbrella stands which is directly rotated by, the opening e has to be set very large. Therefore, water and foreign matter easily enter the inside of the locking device through the opening e, which is the largest cause of failure such as rusting and clogging of foreign matter.

The present invention aims to effectively solve these problems.

[0006]

In order to achieve the above object, the present invention employs the following configuration.

That is, the locking device for an umbrella stand according to the present invention is provided with a supporting member having a concave portion for accommodating the handle of the umbrella on the front surface, and arranged so as to be retracted from the side surface of the concave portion to the concave portion. A lock member provided, an open / close button arranged in the vicinity of the inner end of the recess so as to be able to move forward and backward, and a motion conversion unit converting the forward / backward movement of the open / close button into the forward / backward movement of the locking member. When the opening / closing button is retracted, the locking member is configured to advance into the recess from the opening on the side surface of the recess to connect both side surfaces of the recess for locking, and It is characterized in that the gap between the locking member and the opening is set to be kept substantially constant.

As one mode of implementation of the locking member, there can be mentioned one having a linear shape and adapted to move forward and backward along the straight line.

[0009]

With the locking device for the umbrella stand having such a structure,
By approximating the shape of the opening to the cross-sectional shape of the locking member, the gap between the locking member and the opening can be kept as small as possible during locking and unlocking. Therefore, it is possible to greatly reduce the possibility that moisture or foreign matter may enter the inside of the support member through the gap, and it is possible to eliminate the possibility of failure.
