Abstract

An improved stationery clamp includes a first clamp member, a second clamp member, an adjustable screw bolt and an elastic member to form an adjustable displacement between the first and second clamp member for engaging with a partition of various thickness. The stationery clamp further has a holding slot located on a top side for engaging and supporting various types of stationery set such as paper clip tray, name card rack, mobile phone dock, tape stand or the like. The stationery clamp has great versatility and applicability to mate with different office partitions and hold various types of stationery sets.

Claims

1. An improved stationery clamp having an adjustable displacement to engage with a partition of various thickness, comprising:

a first clamp member including a first flange located at one end thereof and extended downward, a first chamber formed therein which has a front opening, a rod located in the first chamber having a step ring at a selected location dividing the rod in two sections of different diameters, and a holding slot located above the top side thereof, the rod having a front end which has a smaller diameter and a screw bore formed therein;

a second clamp member movable in the first chamber having a second flange located at one end thereof and extended downward, a guide wall located inside thereof forming a second chamber therein mating with the peripheral wall of the rod, an elastic member held in the second chamber having one end pressing against the step ring, and a through hole formed in a rear wall thereof communicating with the second chamber;

an adjustable screw bolt running through the through hole and elastic member for engaging with the screw bore of the rod; and

a stationery set having a ridge located below the bottom side thereof engageable with the holding slot of the first clamp member;

wherein the stationery clamp is engageable with the partition of various thickness to support various types of the stationery set.

2. The improved stationery clamp of claim 1, wherein the first clamp member further has two side walls each has a slide slot of a selected length formed therein, the second clamp member has two side walls each has a resilient stub located thereon for slidably engaging with the slide slot for limiting the adjusting displacement and preventing the second clamp member from disengaging from the first clamp member.

3. The improved stationery clamp of claim 1, wherein the elastic member is a compression spring.

4. The improved stationery clamp of claim 1, wherein the stationery set is selectively a paper clip tray, a name card rack, a mobile phone dock or a tape stand.

5. An improved stationery clamp having an adjustable displacement to engage with a partition of various thickness, comprising:

a first clamp member including a first flange located at one end thereof and extended downward, a first strut extended downward from a top wall thereof, a first bottom lid which has a first aperture, and a holding slot located above the top wall thereof, the first strut having a bottom end which has a first screw hole formed therein for engaging with the first bottom lid through the first aperture;

a second clamp member movable in the first clamp member having a second flange located at one end thereof and extended downward, a second strut extended downward from a top wall thereof, and a second bottom lid which has a second aperture, the second strut having a bottom end which has a second screw hole formed therein for engaging with the second bottom lid through the second aperture;

an elastic member having two ends engaging respectively with the first and second strut; and

a stationery set having a ridge located below the bottom side thereof engageable with the holding slot of the first clamp member;

wherein the stationery clamp is engageable with the partition of various thickness to support various types of the stationery set.

6. The improved stationery clamp of claim 5, wherein the first and second strut have respectively a notch formed thereon for securely holding the elastic member.

7. The improved stationery clamp of claim 5, wherein the first and second bottom lid have respectively a first and second stopper facing each other for limiting the adjusting displacement and preventing the second clamp member from disengaging from the first clamp member.

8. The improved stationery clamp of claim 5, wherein the elastic member is an extension spring.

9. The improved stationery clamp of claim 5, wherein the elastic member is a rubber band.

10. The improved stationery clamp of claim 5, wherein the stationery set is selectively a paper clip tray, a name card rack, a mobile phone dock or a tape stand.
