Abstract

A slide rail has a mounting shaft and a sliding mount. The sliding mount is movably mounted around the mounting shaft and has a clamp, a handle, a clamp jaw, a holding bracket and a spring. The clamp is mounted around the mounting shaft. The handle is rotatably connected to the clamp and has a lock bar and a grip. The clamp jaw is mounted around and abuts the mounting shaft in the clamp and has a convex surface. The holding bracket is connected to the clamp to hold a showerhead, a soap dish or the like and has a positioning ring. The spring is mounted in the clamp between the clamp jaw and the positioning ring to push the convex surface of the clamp jaw to engage an engaging recess of the lock bar.

Claims

1. A slide rail having

a mounting shaft having

an external surface;

two ends; and

a diameter; and

a sliding mount being movably mounted around the mounting shaft and having

a clamp being mounted slidably around the mounting shaft and having

two mounting surfaces;

two ends;

an internal surface;

two mounting holes being respectively formed through the mounting surfaces of the clamp aligned with each other and being mounted around the external surface of the mounting shaft;

a connecting hole being formed in one of the ends of the clamp and communicating with the mounting holes; and

an attaching hole being formed in the other end of the clamp and communicating with the mounting holes and the connecting hole;

a handle being rotatably connected to the clamp and having

a lock bar being rotatably mounted in the connecting hole of the clamp and having

an inner end;

an outer end;

a pressing panel being defined in the inner end of the lock bar, abutting with the internal surface of the clamp near the connecting hole and having

 

a sidewall facing to the external surface of the mounting shaft; and

 

an engaging recess being formed on the sidewall of the pressing panel; and

an arm being polygonal, being defined in the outer end of the lock bar and being formed on and protruding from the pressing panel and extending out of the connecting hole of the clamp;

a clamp jaw being mounted in the clamp and around and abutting the mounting shaft and having

a center;

two sidewalls;

a shaft hole being formed through the center of the clamp jaw, being mounted around the external surface of the mounting shaft and having a diameter larger than the diameter of the mounting shaft; and

a convex surface being formed on one of the sidewalls of the clamp jaw and engaging the engaging recess of the pressing panel;

a holding bracket being connected to the clamp near the attaching hole and having a body having a holding recess; and

a spring being mounted in the clamp between the clamp jaw and the holding bracket.

2. The slide rail as claimed in claim 1, wherein the holding bracket further has

a positioning ring being mounted securely in the clamp near the attaching hole;

a fastener being mounted in the clamp and having

an abutting end being mounted in the clamp and abutting the positioning ring; and

a connecting end being extended through the positioning ring and out of the attaching hole of the clamp;

wherein

the body is connected to the fastener, abuts the clamp near the attaching hole and has

an inner side;

an outer side; and

a threaded hole being formed in the inner side of the body and being screwed with the connecting end of the fastener to connect the body with the clamp through the fastener,

wherein the holding recess is formed in the outer side of the body.

3. The slide rail as claimed in claim 2, wherein the positioning ring further has a washer abutting the abutting end of the fastener.

4. The slide rail as claimed in claim 3, wherein

the clamp further has

two washers being respectively mounted in the mounting holes;

and

an inner thread being formed on the internal surface of the clamp near the attaching hole; and

the positioning ring further has

an external surface; and

an outer thread being formed on the external surface of the positioning ring and being screwed with the inner thread in the internal surface of the clamp near the attaching hole.

5. The slide rail as claimed in claim 4, wherein

the clamp jaw further has a through hole being formed in the clamp jaw at the sidewall opposite to the convex surface and communicating with the shaft hole;

and

the fastener further has a polygonal hole being formed in a top of the abutting end of the fastener and aligning with the through hole of the clamp jaw.

6. The slide rail as claimed in claim 5, wherein the handle further has a grip being mounted around the arm of the pressing panel.

7. The slide rail as claimed in claim 6, wherein

the clamp is a hollow and elliptical in cross-section;

the grip has a shape corresponding to the clamp; and

the body of the holding bracket has a shape corresponding to the clamp.

8. The slide rail as claimed in claim 7, wherein the mounting shaft further has two mounting blocks being respectively formed on the ends of the mounting shaft to mount on a wall.

9. The slide rail as claimed in claim 8, wherein the holding recess is formed longitudinally in the outer side of the body to hold a showerhead.

10. The slide rail as claimed in claim 8, wherein the holding recess is formed transversally in the outer side of the body to hold a soap dish.

11. The slide rail as claimed in claim 1, wherein the handle further has a grip being mounted around the arm of the pressing panel.

12. The slide rail as claimed in claim 11, wherein

the clamp is hollow and elliptical in cross-section;

the grip has a shape corresponding to the clamp; and

the body of the holding bracket has a shape corresponding to the clamp.

13. The slide rail as claimed in claim 1, wherein the mounting shaft further has two mounting blocks being respectively formed on the ends of the mounting shaft to mount on a wall.

14. The slide rail as claimed in claim 1, wherein the holding recess is formed longitudinally in the outer side of the body to hold a showerhead.

15. The slide rail as claimed in claim 1, wherein the holding recess is formed transversally in the outer side of the body to hold a soap dish.
