Abstract

A weighing device includes a tubular housing, a pair of levers pivotally secured the tubular housing and each having a jaw biased to grasp an object to be weighed and a handle for moving the jaws away from each other against a spring. The jaws are movable away from each other to grasp the object when the handles are moved toward each other, such that the handles may actuate the jaws away from each other to grasp the object. Two links have outer ends secured to the levers and inner ends secured together. The spring may bias the links to force the handles away from each other.

Claims

1. A weighing device comprising:

a tubular housing including a first end, a second end, and a middle portion;

a pair of levers including middle portions pivotally secured to said first end of said tubular housing with a shaft, and each including a first end having a jaw provided thereon and extended outward of said tubular housing for grasping an object to be weighed, and each including a second end having a handle extended outward of said tubular housing;

means for biasing said handles away from each other to force said jaws toward each other to grasp the object; and

means for weighing the object, said weighing means including a graduation provided on said tubular housing, a barrel slidably engaged on said second end of said tubular housing, a post received on said barrel and having a first end secured to said barrel and having a second end, and a spring engaged between said second end of said post and engaged with said tubular housing for biasing said second end of said post toward said first end of said tubular housing;

said jaws being movable away from each other to engage with and to grasp the object when said handles are moved toward each other against said biasing means.

2. The weighing device according to claim 1, wherein said biasing means includes a first link and a second link each having an outer end pivotally secured to said levers, and each having an inner end received in said tubular housing.

3. The weighing device according to claim 2, wherein said biasing means includes a spring engaged with said inner ends of said links, for biasing said links to move said handles away from each other.

4. The weighing device according to claim 2, wherein said first link includes an opening formed therein for receiving said inner end of said second link, and a pivot rod engaged through said inner ends of said links.

5. The weighing device according to claim 4, wherein said tubular housing includes a pair of grooves formed therein for slidably receiving said pivot rod.

6. The weighing device according to claim 2, wherein said tubular housing includes a pair of channels formed in said middle portion thereof, for slidably receiving said links respectively.

7. The weighing device according to claim 1 further comprising an insert engaged in said first end of said tubular housing, and including a hole formed therein for receiving said shaft, and for securing said insert in said first end of said tubular housing.

8. The weighing device according to claim 7, wherein said insert includes a first and a second member, said first member includes at least one depression formed therein, said second member includes at least one stud extended therefrom and engaged into said at least one depression of said first member for securing said first and said second members together.

9. The weighing device according to claim 7, wherein said tubular housing includes a pair of slots formed in said first end thereof for slidably receiving said middle portions of said levers, said insert includes a notch formed therein and aligned with said slots of said tubular housing, for receiving said middle portions of said levers.

10. The weighing device according to claim 7, wherein said tubular housing includes a pair of channels formed therein, said insert includes a passage formed therein and aligned with said channels of said tubular housing.

11. The weighing device according to claim 10, wherein said biasing means includes a pair of links each having an outer end pivotally secured to said levers, and each having an inner end slidably received in said channels of said tubular housing and said passage of said insert.

12. The weighing device according to claim 11, wherein said biasing means includes a spring engaged with said inner ends of said links, for biasing said links to move said handles away from each other.

13. The weighing device according to claim 12, wherein said insert includes a chamber formed therein for receiving said spring.

14. The weighing device according to claim 12, wherein said biasing means includes a follower engaged in said spring and having an enlarged head engaged with said inner ends of said links.

15. The weighing device according to claim 11, wherein a first one of said pair of links includes an opening formed therein for receiving said inner end of a second one of said pair of links, and a pivot rod engaged through said inner ends of said pair of links.

16. The weighing device according to claim 15, wherein said tubular housing includes a pair of grooves formed therein for slidably receiving said pivot rod.
