Abstract

The present invention discloses a shading device includes a screen, a shaft portion having a lock portion to be locked, a biasing mechanism, a locking member that is engaged at a lock position with the lock portion, and a housing in which the end portion of the shaft portion is inserted. The housing has a sliding guide portion in which the locking member is slid. The sliding guide portion is capable of guiding the locking member in a direction passing through the lock position and a lock release position, and has a lock position engagement portion for stopping the locking member from sliding at the lock position. The locking member includes a slide engagement portion that engages with the lock position engagement portion at the lock position and an operating portion that can be flexed to release the slide engagement portion from the lock position engagement portion.

First claim

What is claimed is:

1. A shading device, comprising:
a screen;
a shaft portion to which one end of the screen is fastened, the shaft portion having a lock portion to be locked, the lock portion being formed at an end portion of the shaft portion;
a biasing mechanism that biases the shaft portion in a winding direction of the screen;
a locking member that engages with the lock portion at a lock position where the locking member prohibits a rotation of the shaft portion; and
a housing into which the end portion of the shaft portion is inserted, the housing having a sliding guide portion in which the locking member is slid, wherein
the sliding guide portion is capable of guiding the locking member in a direction passing through the lock position and a lock release position where the lock portion is released from the locking member, and the sliding guide portion further includes a lock position engagement portion for stopping the locking member from sliding at the lock position, and
the locking member includes a slide engagement portion that engages with the lock position engagement portion at the lock position and an operating portion that can be flexed to release the slide engagement portion from the lock position engagement portion.

2. The shading device according to claim 1 , wherein
the sliding guide portion includes a release position engagement portion that engages with the slide engagement portion of the locking member at the lock release position, and
the operating portion can be flexed to release the slide engagement portion from the release position engagement portion.

3. The shading device according to claim 1 , wherein
the locking member includes a pair of the operating portions that can be flexed in a clamping direction with respect to a track of sliding and a pair of the slide engagement portions that are simultaneously moved with each of the operating portions,
the pair of the slide engagement portions is formed facing outward with respect to the track and opposing to each other, and
the sliding guide portion includes a pair of the lock position engagement portions that engage with each of the slide engagement portions.

4. The shading device according to claim 1 , wherein
the housing includes a groove that is directed in the direction passing through the lock position and the lock release position, and
the locking member includes a sliding piece that is slidably inserted into the groove.

5. The shading device according to claim 1 , wherein
a second lock release position is provided in the direction passing through the lock position and the lock release position, and
the sliding guide portion prohibits the locking member from sliding to the lock position when the locking member is slid to the second lock release position.

6. The shading device according to claim 1 , wherein
the locking member is removed from the housing when the locking member is slid from the lock position to an opposite side of the lock release position.
