Abstract

A folding device with a safe retainer comprises a base and a seat axially connected with each other, and a quick release assembly axially coupled to the connected base and seat, wherein the base includes a hole disposed on one side thereof and a tab mounted on another side thereof, and the seat includes a first connecting sleeve to correspond to the hole and a second connecting sleeve to correspond to the tab; the quick release assembly includes an engaging member and an adjusting shaft member axially connected with each other, and the engaging member includes a bore disposed on a lower end thereof to insert a first stem, and the adjusting shaft member includes a coupling segment formed on a lower side thereof to be pivoted to the tab of the base by using a second stem.

Claims

1. A folding device with a safe retainer comprising

a base and a seat axially connected with each other, and a quick release assembly axially coupled to the connected base and seat;

the base including a hole disposed on one side thereof and a tab mounted on another side thereof, and the seat including a first connecting sleeve fixed on one side thereof to correspond to the hole and a second connecting sleeve secured on another side thereof to correspond to the tab;

the quick release assembly including an engaging member and an adjusting shaft member axially connected with each other, and the engaging member including a bore disposed on a lower end thereof to insert a first stem, and the adjusting shaft member including a coupling segment formed on a lower side thereof to be pivoted to the tab of the base by using a second stem;

wherein

between one end of the adjusting shaft and the second stem is defined a pillar, and the engaging member includes a positioning peg disposed thereon to engage the pillar, and the positioning peg includes a button fitted thereon so that the pillar moves in the positioning peg.

2. The folding device with a safe retainer as claimed in claim 1, wherein the adjusting shaft member of the quick release assembly and the second stem 5 are hollow and have a closed end respectively, and the second stem includes a groove arranged therein to receive a compression spring and a pillar.

3. The folding device with a safe retainer as claimed in claim 1, wherein the pillar includes an arcuate end portion extending out of the second stem.

4. The folding device with a safe retainer as claimed in claim 2, wherein the pillar includes an arcuate end portion extending out of the second stem.

5. The folding device with a safe retainer as claimed in claim 1, wherein the button includes a slot formed therein, and the second stem includes a third aperture radially disposed in the groove so that a second screw allows to be positioned to the indention of the pillar through the groove.

6. The folding device with a safe retainer as claimed in claim 1, wherein the button is formed in a T shape, the positioning peg includes a first aperture radially fixed therein in response to the positioning peg.

7. The folding device with a safe retainer as claimed in claim 1, wherein a connection of the elongated side of the engaging member and the positioning peg is provided with a beveled surface.

8. The folding device with a safe retainer as claimed in claim 1, wherein the second stem is fixed to the coupling segment of the adjusting shaft member.
