Abstract

A screw clamp includes a clamping device having a follower and a coupling extension extended downwardly from the follower, and one or more anchoring elements disposed below the follower and each pivotally attached to the coupling extension with a pivot axle for engaging with the table plate, the follower includes a screw hole, the anchoring element is pivotable relative to the coupling extension between a working position parallel to the coupling extension and a folded position perpendicular to the coupling extension, and a fastener is engaged with the screw hole of the follower for moving the follower relative to the table plate and to be secured to the table plate with the fastener.

First claim

I claim:

1 . A screw clamp for attaching to a table plate, comprising:
a clamping device including a follower to be supported on the table plate, a coupling extension extended downwardly from said follower, and an anchoring element provided below said follower and pivotally attached to said coupling extension of said follower with a pivot axle for engaging with the table plate, said follower including a screw hole formed therein, said anchoring element being pivotable relative to said coupling extension between a first position where said anchoring element is parallel to said coupling extension, and a second position where said anchoring element is perpendicular to said coupling extension, and a fastener engaged with said screw hole of said follower for moving said follower up and down relative to the table plate when said fastener is rotated relative to said follower, for allowing said follower to be secured to the table plate with said fastener.

2 . The screw clamp as claimed in claim 1 , wherein said anchoring element includes a tilted lower surface inclined relative to said coupling extension and said pivot axle.

3 . The screw clamp as claimed in claim 1 , wherein said anchoring element includes a flat upper surface perpendicular to said coupling extension and parallel to said follower and the table plate.

4 . The screw clamp as claimed in claim 1 further comprising a spring biasing member engaged with said coupling extension and said anchoring element for biasing and forcing said anchoring element to said second position where said anchoring element is perpendicular to said coupling extension.

5 . The screw clamp as claimed in claim 1 further comprising a carrier member including a compartment formed therein, said carrier member including a through hole formed in said carrier member and communicating with said compartment of said carrier member and aligned with said screw hole of said follower for engaging with said fastener, and said carrier member including an attachment mechanism for attaching a facility.

6 . The screw clamp as claimed in claim 5 , wherein said compartment of said carrier member includes a non-circular cross section and opened downwardly and rearwardly, and said follower includes a non-circular cross section for being guided and limited to slide up and down relative to said compartment of said carrier member and for preventing said follower from being rotated relative to said carrier member.

7 . A screw clamp for attaching to a table plate, comprising:
a clamping device including a follower to be supported on the table plate, a coupling extension extended downwardly from said follower, and two anchoring elements provided below said follower and each pivotally attached to said coupling extension of said follower with a pivot axle for engaging with the table plate, said follower including a screw hole formed therein, said anchoring elements being pivotable relative to said coupling extension between a first position where said anchoring element is parallel to said coupling extension, and a second position where said anchoring element is perpendicular to said coupling extension, and a fastener engaged with said screw hole of said follower for moving said follower up and down relative to the table plate when said fastener is rotated relative to said follower, for allowing said follower to be secured to the table plate with said fastener.

8 . The screw clamp as claimed in claim 7 , wherein said anchoring elements each include a tilted lower surface inclined relative to said coupling extension and said pivot axle.

9 . The screw clamp as claimed in claim 7 , wherein said anchoring elements each include a flat upper surface perpendicular to said coupling extension and parallel to said follower and the table plate.

10 . The screw clamp as claimed in claim 7 further comprising a spring biasing member engaged with said coupling extension and each said anchoring element for biasing and forcing said anchoring element to said second position where said anchoring element is perpendicular to said coupling extension.

11 . The screw clamp as claimed in claim 7 further comprising a carrier member including a compartment formed therein, said carrier member including a through hole formed in said carrier member and communicating with said compartment of said carrier member and aligned with said screw hole of said follower for engaging with said fastener, and said carrier member including an attachment mechanism for attaching a facility.
