Hook Clamp

Abstract

A hook clamp includes a clamping module and a base. The clamping module includes a curved member and a movable member. The curved member includes a head. The movable member includes a groove corresponding to the curved member and an engaging member corresponding to the head. The base includes a rail and a limiting member. The rail is configured to guide a motion of the movable member. The limiting member is configured to limit the curved member to move between a first position and a second position. The head is pushed by the limiting member to engage the engaging member when the movable member moves along the rail to the first position. The first end portion of the curved member is pushed by the limiting member so that the head is separated from the engaging member when the movable member moves along the rail to the second position.

What is claimed is: 
     
         1 . A hook clamp, comprising:
 a clamping module comprising a curved member and a movable member, wherein the curved member comprises a head and a first end portion opposite to the head, and the movable member comprises a groove corresponding to the curved member and an engaging member corresponding to the head; and   a base comprising a rail and a limiting member, wherein the rail is configured to guide a motion of the movable member, and the limiting member is configured to limit the curved member to move between a first position and a second position;   wherein the head is pushed by the limiting member to engage the engaging member when the movable member moves along the rail to the first position;   wherein the first end portion of the curved member is pushed by the limiting member so that the head is separated from the engaging member when the movable member moves along the rail to the second position.   
     
     
         2 . The hook clamp as claimed in  claim 1 , wherein the curved member is a rocker, the engaging member of the movable member is an engaging groove, the curved member further comprises a second end portion from which the head extends downward, a plurality of connecting posts disposed on two lateral sides of the curved member, and the movable member further comprises a rocker groove corresponding to the rocker, a plurality of notches corresponding to the connecting posts, and a force receiving part. 
     
     
         3 . The hook clamp as claimed in  claim 2 , wherein the base further comprises a securing flange. 
     
     
         4 . The hook clamp as claimed in  claim 2 , wherein the curved member further comprises a first stopping member transversely disposed on the first end portion of the curved member. 
     
     
         5 . The hook clamp as claimed in  claim 2 , wherein the movable member further comprises a second stopping member disposed beside an end of the rocker groove. 
     
     
         6 . A bed, comprising:
 a mattress;   a bottom sheet; and   the hook clamp as claimed in  claim 1 , mounted on the mattress for securing the bottom sheet to the mattress.   
     
     
         7 . The bed as claimed in  claim 6 , wherein the mattress is an inflatable mattress. 
     
     
         8 . The bed as claimed in  claim 7 , wherein the hook clamp is welded to the inflatable mattress.
