Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 60/667,621, filed on Apr. 1, 2005, entitled Pole Support Tube; the prior application is herewith incorporated by reference in its entirety.
- 1. Field of the Invention
- The present invention pertains to a pole support tube which supports a canvas tarp or cover. More specifically, to a pole support tube that can support a tarp that has a load applied thereon.
- 2. Description of the Related Art
- Pole support tubes are generally used in the rear of a boat. One or more of the pole support tubes may be used to support a canvas. The pole support tube(s) serve to support the canvas to prevent weather (snow, ice, water etc.) from puddling or pooling on the canvas (
FIG. 4 ). - A pole support tube includes two sections; one section is an outer section and the other section is an inner section, such that the inner section telescopes within the outer section.
- At the bottom of the pole support tube is a foot end of rubber material that fits snuggly over a base of the pole support tube. The top of the pole attaches to the canvas either with a universal snap or with a tent pole type end that fits within a grommeted hole formed in the canvas.
- The support pole tubes are generally provided in collapsed lengths of 24 and 30 inches. The height of the pole support tube is adjusted to and held in place by either a locking pin, spring-loaded ball, a setscrew, or by a rotational movement between the inner and outer sections. The disadvantage of the locking pin and the spring-loaded ball is that the adjustment of the length of the pole support tube is limited to the locations where holes are provided. The disadvantages of a setscrew and the rotational movement between the tubes is the amount of time to tighten and set the length, it is also possible that the adjusted length will slip because of awkwardness of setting the screw with the weight of the tarp being supported, and it is possible to lose the setscrew.
- It is accordingly an object of the invention to provide a pole support tube which overcomes the above-mentioned disadvantages of the heretofore-known devices of this general type and which provides a pole support tube that is more versatile and easier to use.
- The pole support tube is adjustable to infinite extended positions by the cam assembly. The cam assembly includes a lever that allows for quick and easy settings of the length of the pole support tube. The present invention also has the advantage that the inner section has a snap on one end and a tent pole type end on the other end. This makes the inner section reversible and allows the pole support tube to accommodate tarps with either a snap or a grommet. The present invention includes a roughening or surface texturing of the outside diameter of the inner section to increase the holding force with respect to the cam assembly of the pole support tube. It is also possible to adjust the holding force of the pole support tube by changing the durometer of a pressure pad of the cam assembly.
- With the foregoing and other objects in view there is provided, a pole support tube which includes an inner tube having an outside diameter. The outside diameter has a textured surface finish. The pole support tube has an outer tube. A cam assembly is disposed on the outer pole and engages the textured surface finish of the inner tube. The cam assembly locks the inner tube in place with respect to the outer tube
- In accordance with another feature of the invention, the cam assembly has a lever and a pressure pad. The lever activates the pressure pad to engage the textured surface finish.
- In accordance with an added feature of the invention, the inner tube has an end that is configured to engage a grommet of a tarp.
- In accordance with an additional feature of the invention, the inner tube has an end that is configured to engage a snap on a tarp.
- In accordance with yet an additional feature of the invention, the second tube has a rubber foot.
- In accordance with a further feature of the invention, the surface texture is rough enough to supporting a load in the range of 120-150 pounds.
- In accordance with another mode of the invention, there is provided a pole support tube which includes an inner tube having an outer diameter. The pole support includes an outer tube. A cam assembly is disposed on the outer tube, the cam assembly has a pressure pad. The pressure pad engages the outer diameter for locking the inner tube in place with respect to the outer tube. The inner tube and the pressure pad have a coefficient of friction therebetween that is capable of supporting a load in the range of 120-150 pounds.
- Other features which are considered as characteristic for the invention are set forth in the appended claims.
- Although the invention is illustrated and described herein as embodied as a pole support tube for supporting a tarp or cover, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
- The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
-
FIG. 1 is a sectional view of the pole support tube according to the invention showing an inner section with a tent pole type end; -
FIG. 2 is a sectional view of the pole support tube according to the invention showing an inner section with a snap end; and -
FIG. 3 is a sectional view of the pole support tube according to the invention showing an inner section with a snap end and a tent pole type end. - Referring now to the figures of the drawing in detail and first, particularly,
FIGS. 1, 2 , and 3 illustrate a pole support tube having an inner section or inner tube 1 and an outer section orouter tube 2. Included on a free end of theouter section 2 is arubber foot 3. The inner section includes either a universal snap end 4 (FIG. 2 ) or a tent pole type end 5 (FIG. 2 ), or as shown inFIG. 3 the inner section 1 can have both theuniversal snap 4 and the tentpole type end 5 on opposite ends thereof. - The
pole support tube 10 can be adjusted to infinite extended lengths by acam assembly 20. Thecam assembly 20 is disposed on theouter section 2 at the outer diameter of theouter section 2. Thecam assembly 20 includes arotatable lever 21 that allows for a quick and easy setting of the length of the pole support tube. Thelever 21 activates apressure pad 23 that engages the outer diameter of the inner section 1 through a hole formed in the outer section. In the activated position of thepressure pad 23, i.e. when the pole support tube is ready to support a tarp, the pole support tube must be able to support a load in the range of 120-150 pounds. This can be achieved in several different ways, for example, by increasing the coefficient of friction of the outer diameter of the inner section 1 with an abrasive finish, a roughening, or with a texturing on the outer diameter of the inner section 1. In trials performed by applicant using an untextured or smooth inner section 1, the pole support tube was only capable of supporting a load of 60 pounds before slipping occurred. Alternatively, it is also possible to use a material on the surface of thepressure pad 23 that has a lower durometer, thereby increasing the coefficient of friction of thepressure pad 23. Any combinations for increasing the coefficient of friction of thepressure pad 23 and/or the coefficient of friction of the outer diameter of the inner section 1 is acceptable for achieving the desired holding forces.
