Abstract

A safety seat base includes a base body, an indicating member and a support foot. The base body includes a frame. The frame has an indicating window. The indicating member is rotatably connected to the frame. The indicating member has a first color block. The support foot is rotatably connected to the frame. The support foot a protruding portion. When the support foot rotates to an unfolded position, the protruding portion pushes the indicating member to rotate upward, such that the indicating window shows the first color block.

First claim

The invention claimed is:

1 . A safety seat base comprising:
a base body comprising a frame, the frame having an indicating window; an indicating member rotatably connected to the frame, the indicating member including a first color block; and a support foot rotatably connected to the frame, the support foot having a protruding portion; wherein when the support foot rotates to an unfolded position, the protruding portion pushes the indicating member to rotate upward, such that the indicating window shows the first color block, wherein the indicating member further includes a second color block and the first color block is visually different from the second color block; when the support foot rotates away from the unfolded position, the indicating member rotates downward, such that the indicating window shows the second color block, wherein when the support foot is unfolded incompletely, the indicating window shows a part of the first block and a part of the second color block.

2 . The safety seat base according to claim 1 , wherein when the support foot rotates away from the unfolded position, the indicating member rotates downward, such that the first color block disappears from the indicating window.

3 . The safety seat base according to claim 1 , wherein the support foot comprises a first support member, a second support member, a fixing socket and a lock member, the first support member is rotatably connected to the frame, the second support member is telescopically connected to the first support member, the second support member has a plurality of engaging holes, the fixing socket is disposed on the first support member, the lock member is rotatably connected to the fixing socket, the lock member has an engaging portion and an operating portion, and the engaging portion engages with one of the engaging holes to lock the first support member and the second support member; when the operating portion is pressed, the engaging portion disengages from the engaging hole, such that the second support member is able to move with respect to the first support member.

4 . The safety seat base according to claim 3 , wherein the support foot further comprises a torsion spring, the torsion spring is disposed in the fixing socket, and two ends of the torsion spring respectively abut against the first support member and the fixing socket.

5 . The safety seat base according to claim 1 , wherein the support foot comprises a cover and the protruding portion protrudes from a side of the cover.

6 . The safety seat base according to claim 1 , further comprising a torsion spring, two ends of the torsion spring respectively abut against the support foot and the frame, and the torsion spring biases the support foot toward the unfolded position.

7 . The safety seat base according to claim 1 , further comprising an elastic sheet, the elastic sheet is disposed on the frame, and the elastic sheet restrains the support foot from rotating toward the unfolded position.

8 . The safety seat base according to claim 7 , further comprising an alarm device and the alarm device is disposed on the base body; when the support foot is unfolded incompletely, the alarm device sends out an alarm message; when the support foot is unfolded completely, the elastic sheet triggers the alarm device to stop sending out the alarm message.

9 . The safety seat base according to claim 1 , wherein the frame includes a first restraining portion, the indicating member includes a second restraining portion, and the first restraining portion cooperates with the second restraining portion to restrain the indicating member from rotating downward.

10 . The safety seat base according to claim 1 , further comprising an alarm device and the alarm device is disposed on the base body; when the support foot is unfolded incompletely, the alarm device sends out an alarm message; when the support foot is unfolded completely, the alarm device stops sending out the alarm message.

11 . The safety seat base according to claim 10 , wherein when the support foot is unfolded completely, the indicating member triggers the alarm device to stop sending out the alarm message.

12 . A safety seat base comprising:
a base body comprising a frame, the frame having an indicating window; an indicating member rotatably connected to the frame, the indicating member including a first color block; and a support foot rotatably connected to the frame, the support foot having a protruding portion; wherein when the support foot rotates to an unfolded position, the protruding portion pushes the indicating member to rotate upward, such that the indicating window shows the first color block, wherein the safety seat base further comprises:
a torsion spring, two ends of the torsion spring respectively abut against the support foot and the frame, and the torsion spring biases the support foot toward the unfolded position; or
an elastic sheet, the elastic sheet is disposed on the frame, and the elastic sheet restrains the support foot from rotating toward the unfolded position.

13 . A safety seat base comprising:
a base body comprising a frame, the frame having an indicating window; an indicating member rotatably connected to the frame, the indicating member including a first color block; and a support foot rotatably connected to the frame, the support foot having a protruding portion; wherein when the support foot rotates to an unfolded position, the protruding portion pushes the indicating member to rotate upward, such that the indicating window shows the first color block, wherein the safety seat base further comprises an alarm device and the alarm device is disposed on the base body; when the support foot is unfolded incompletely, the alarm device sends out an alarm message; when the support foot is unfolded completely, the alarm device stops sending out the alarm message.
