1. FIELD OF THE INVENTION
The present invention relates to a unique supporting and protecting system for a recreational-vehicle sewer hose. Particularity, the present invention relates to a unique sewer-hose-supporting-and-protecting system having quick-lock-and-quick-release stake-clamping jaws, quick-lock-and-quick-release jaw-squeezing chambers, multi-purpose two-way stakes, and sequential-locking joints. The unique sewer-hose-supporting-and-protecting system is quick, easy, convenient, and safe to assemble, adjust, and disassemble for quickly locking, quickly releasing, supporting, and protecting a recreational-vehicle sewer hose, in a desired shape and at a desired height and angle, to overcome all the disadvantages of prior art.
2. DESCRIPTION OF THE PRIOR ART
A number of inventions for supporting and/or protecting a recreational-vehicle sewer hose have been introduced. U.S. Pat. No. 4,715,570, filed Jul. 7, 1986, to Mashuda, David; U.S. Pat. No. 4,722,500, filed May 30, 1986, to Bray, Jaycee; U.S. Pat. No. 4,905,939, filed Jul. 10, 1989, to Horn, Chris; U.S. Pat. No. 5,067,679, filed Dec. 6, 1990, to Courtney, Charles; U.S. Pat. No. 5,431,455, filed Aug. 5, 1994, to Seely, Stanley; U.S. Pat. No. 5,788,193, filed Jul. 5, 1996, to Hilbert, Gary; U.S. Pat. No. 6,003,819, filed Dec. 30, 1997, to Hall, Carl; U.S. Pat. No. 6,186,449, filed Jun. 30, 1999, to Chrestenson, Robert; U.S. Pat. No. 6,250,847, filed Mar. 24, 1999, to Bingham, Jr., Thomas; U.S. Pat. No. 6,619,596, filed May 2, 2002, to Caine, Donald, Brockington, William, Moore, Antony, and Geible, Norman; U.S. Pat. No. 6,877,700, filed Aug. 28, 2002, to Smith, Dennis; U.S. Pat. No. 7,425,028, filed Nov. 29, 2006, to Angel, Bruce; and U.S. Pat. No. 7,434,771, filed Nov. 14, 2006, to Tai, Lo Yun disclose a variety of systems for supporting and/or protecting a recreational-vehicle sewer hose. All the prior-art inventions have failed to solve many inherent problems associated with such system, as follows:
1) The problems of personal injuries when a user has to overcome the permanent clamping forces from the nuts clamping each of the stakes of the prior-art systems (which prevent the stakes from moving freely at all times). These problems create a lot of pain and difficulties every time a user assembles, disassembles, and adjusts the prior-art systems, especially when the stakes are wet and/or rusted (for example, U.S. Pat. No. 5,431,455 mentioned above);

2) The problems of hazardously and costly unsanitary conditions as a result of personal injuries when a user has to overcome the permanent clamping forces from the nuts clamping each of the stakes of the prior-art systems (which prevent the stakes from moving freely at all times). These problems create a lot of pain and difficulties every time a user assembles, disassembles, and adjusts the prior-art systems, especially when the stakes are wet and/or rusted (for example, U.S. Pat. No. 5,431,455 mentioned above);

3) The problems of hazardous and costly infections as a result of personal injuries when a user has to overcome the permanent clamping forces from the nuts clamping each of the stakes of the prior-art systems (which prevent the stakes from moving freely at all times). These problems create a lot of pain and difficulties every time a user assembles, disassembles, and adjusts the prior-art systems, especially when the stakes are wet and/or rusted (for example, U.S. Pat. No. 5,431,455 mentioned above);

4) The problems of hazardous and costly diseases as a result of personal injuries when a user has to overcome the permanent clamping forces from the nuts clamping each of the stakes of the prior-art systems (which prevent the stakes from moving freely at all times). These problems create a lot of pain and difficulties every time a user assembles, disassembles, and adjusts the prior-art systems, especially when the stakes are wet and/or rusted (for example, U.S. Pat. No. 5,431,455 mentioned above);

5) The problems of tearing and/or damaging of the recreational-vehicle sewer hose caused by exposure to weather conditions, especially where the recreational-vehicle sewer hose changes its direction and orientation (for example, U.S. Pat. No. 5,431,455 and U.S. Pat. No. 4,905,939 mentioned above);

6) The problems of sagging, tearing, and damaging of the recreational-vehicle sewer hose caused by unsupported weight within the recreational-vehicle sewer hose, especially where the sewer hose changes its direction and orientation (for example, U.S. Pat. No. 5,431,455 mentioned above);

7) The problems of sagging, tearing, and damaging of the recreational-vehicle sewer hose as a result of dragging them on the ground (for example, U.S. Pat. No. 5,431,455 mentioned above); and

8) The problems of the general inconvenience associated with elevating each section of the recreational-vehicle sewer hose at a desired angle and connecting the recreational-vehicle sewer hose to the sewage-holding tank.

Therefore, while these above-mentioned systems are fulfilling their respective, particular objectives, there exists a continuing need for a new, improved, durable, safe, and quick-and-easy-to-operate sewer-hose-supporting-and-protecting system. In this regard, the present invention substantially fulfills this need.
OBJECTS AND ADVANTAGES OF THE INVENTION
The sewer-hose-supporting-and-protecting system overcomes all the disadvantages of the prior art heretofore. The sewer-hose-supporting-and-protecting system substantially departs from the conventional concepts and designs of the prior art. In doing so, the sewer-hose-supporting-and-protecting system provides many unique, significant advantages, some of which are, as follows:
1) It is an object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, which can be used right side up and/or upside down for multi purposes of supporting and protecting a recreational-vehicle sewer hose (This eliminates the problem of the prior art or their components not being able to be used upside down) (for example, U.S. Pat. No. 4,905,939 mentioned above).

2) It is another object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose quick-lock-and-quick-release stake-clamping jaws can quickly and easily lock and release the multi-purpose two-way stakes of the system, to eliminate the use of permanent frictional forces between stakes and nuts in the prior art every time a user assembles, adjusts, disassembles the system and the hose. As a result, this allows the stakes to move freely without any friction, and enables quick, easy, convenient, and safe assembly, adjustment, and disassembly of the system for different shape, height, and angle, to eliminate the risk of personal injuries, infections, and diseases (This eliminates the problem of personal injuries, infections, and diseases caused by the permanent frictional forces required at all times between the rusted stakes and nuts in the prior art) (for example, U.S. Pat. No. 5,431,455 mentioned above).

3) It is a further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose quick-lock-and-quick-release stake-clamping jaws can quickly and easily lock and release the system at a desired height and angle, by simply rotating the multi-purpose two-way stakes of the system just 45 degrees, to eliminate the use of permanent frictional forces between stakes and nuts in the prior art every time a user adjusts the system and the hose to a desired height and angle. As a result, this allows the stakes to move freely without any friction, and enables quick, easy, convenient, and safe assembly, adjustment, and disassembly of the system for different shape, height, and angle (This eliminates the problem of personal injuries, infections, and diseases caused by the permanent frictional forces required at all times between the rusted stakes and nuts in the prior art).

4) It is an even further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose multi-purpose two-way stakes:

    
    
        Can be used right side up or upside down for multi purposes of supporting, stabilizing, and preventing the system from sinking into the ground;
        Can move freely up and down without any friction:
        
            a) To quickly and easily adjust the height of the system to eliminate the risk of personal injury
            
                (This capability overcomes the disadvantage of the prior art. The prior art uses frictional force and, therefore, prevents its respective stakes from moving freely up and down, creating the risk of personal injury, especially, when its stakes are rusted), and
            
            
            b) To quickly and easily assemble, adjust, and disassemble the system to extend the service lifespan of the system
            
                (This capability overcomes the disadvantage of the prior art. The prior art uses permanent frictional force and, therefore, prevents its respective stakes from moving freely up and down, requiring a large amount of physical effort to assemble, adjust, and disassemble the system, especially, when its stakes are rusted);
            
            
        
        
        Can poke into the ground to maintain a desired shape of and to stabilize all the components of the system; and
        Only need to rotate just 45 degrees to quickly and easily lock or release the system at or from a desired height and angle, respectively.
    
    


(This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are damaged after a period of use).
5) It is still another object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose pipe-locking nipples and pipe-locking grooves sequentially lock sequential-locking end joints, sequential-locking middle joints, and sequential-locking pipes of the system together, to withstand repetitive impacts while in use, without falling apart (This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are sagging and falling apart after a period of use).

6) It is still a further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose sequential-locking end joints, sequential-locking middle joints and sequential-locking pipes can curve in, any desired direction and angle for the system to form any desired shape while supporting and protecting a recreational-vehicle sewer hose (This eliminates the problem of the difficulty and inconvenience in assembling, adjusting, and disassembling the cumbersome, time-consuming, difficult-to-operate components of the prior art).

7) It is still an even further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose sequential-locking end joints, sequential-locking middle joints, and sequential-locking pipes can securely function, both right side up and upside down, to support and protect a recreational-vehicle sewer hose, at the same time (This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are sagging and falling apart after a period of use).

8) It is still yet another object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose components sequentially lock one another to withstand repetitive impacts while in use, without sagging or falling apart (This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are sagging and falling apart after a period of use).

9) It is still yet a further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, which will securely function both right side up and upside down, will not sag over a long distance, and thus will not eventually bend or break over extended periods of use (This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are sagging and falling apart after a period of use).

Therefore, the new recreational-vehicle sewer-hose-supporting-and-protecting system is quick, easy, convenient, and safe to assemble, adjust, and disassemble for supporting and protecting a recreational-vehicle sewer hose, in a desired shape and at a desired height and angle. As a result, the new recreational-vehicle sewer-hose-supporting-and-protecting system overcomes all the disadvantages of the prior art. These above and additional advantages are described and illustrated in the following examples and illustrations.

                    (This capability overcomes the disadvantage of the prior art. The prior art uses frictional force and, therefore, prevents its respective stakes from moving freely up and down, requiring a large amount of physical effort to assemble, adjust, and disassemble the system, especially, when its stakes are rusted), and

                    (This capability overcomes the disadvantage of the prior art. The prior art uses frictional force and, therefore, prevents its respective stakes from moving freely up and down, requiring a large amount of physical effort to assemble, adjust, and disassemble the system, especially, when its stakes are rusted);
                
                
            
            
            Can poke into the ground to maintain a desired shape of and to stabilize all the components of the system; and

Any of sequential-locking pipes 46 can be straight or curved at a predetermined angle and orientation to support and/or protect a recreational-vehicle sewer hose, in a predetermined shape and at a predetermined height and angle. For example, any of sequential-locking pipes 46 can curve 30 degrees, 45 degrees, 60 degrees, 90 degrees, or any degrees in between.
The cross-section of each screw tunnel 54 and its mating multi-purpose two-way stake 45 can have any shape and size.

As a result, a user can quickly and safely assemble, disassemble, and adjust the sewer-hose-supporting-and-protecting system, to support and protect a recreational-vehicle sewer hose.
Unique Advantages of the Present System Versus Prior-Art Disadvantages
The sewer-hose-supporting-and-protecting system overcomes all the disadvantages of the prior art heretofore. The sewer-hose-supporting-and-protecting system substantially departs from the conventional concepts and designs of the prior art. In doing so, the sewer-hose-supporting-and-protecting system provides many unique, significant advantages, some of which are, as follows:
1) It is an object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, which can be used right side up and/or upside down for multi purposes of supporting and protecting a recreational-vehicle sewer hose (This eliminates the problem of the prior art or their components not being able to be used upside down) (for example, U.S. Pat. No. 4,905,939 mentioned above).

2) It is another object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose quick-lock-and-quick-release stake-clamping jaws can quickly and easily lock and release the multi-purpose two-way stakes of the system, to eliminate the use of permanent frictional forces between stakes and nuts in the prior art every time a user assembles, adjusts, disassembles the system and the hose. As a result, this allows the stakes to move freely without any friction, and enables quick, easy, convenient, and safe assembly, adjustment, and disassembly of the system for different shape, height, and angle, to eliminate the risk of personal injuries, infections, and diseases (This eliminates the problem of personal injuries, infections, and diseases caused by the permanent frictional forces required at all times between the rusted stakes and nuts in the prior art) (for example, U.S. Pat. No. 5,431,455 mentioned above).

3) It is a further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose quick-lock-and-quick-release stake-clamping jaws can quickly and easily lock and release the system at a desired height and angle, by simply rotating the multi-purpose two-way stakes of the system just 45 degrees, to eliminate the use of permanent frictional forces between stakes and nuts in the prior art every time a user adjusts the system and the hose to a desired height and angle. As a result, this allows the stakes to move freely without any friction, and enables quick, easy, convenient, and safe assembly, adjustment, and disassembly of the system for different shape, height, and angle (This eliminates the problem of personal injuries, infections, and diseases caused by the permanent frictional forces required at all times between the rusted stakes and nuts in the prior art).

4) It is an even further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose multi-purpose two-way stakes:

    
    
        Can be used right side up or upside down for multi purposes of supporting, stabilizing, and preventing the system from sinking into the ground;
        Can move freely up and down without any friction:
        
            a) To quickly and easily adjust the height of the system to eliminate the risk of personal injury
            
                (This capability overcomes the disadvantage of the prior art. The prior art uses frictional force and, therefore, prevents its respective stakes from moving freely up and down, creating the risk of personal injury, especially, when its stakes are rusted), and
            
            
            b) To quickly and easily assemble, adjust, and disassemble the system to extend the service lifespan of the system
            
                (This capability overcomes the disadvantage of the prior art. The prior art uses permanent frictional force and, therefore, prevents its respective stakes from moving freely up and down, requiring a large amount of physical effort to assemble, adjust, and disassemble the system, especially, when its stakes are rusted);
            
            
        
        
        Can poke into the ground to maintain a desired shape of and to stabilize all the components of the system; and
        Only need to rotate just 45 degrees to quickly and easily lock or release the system at or from a desired height and angle, respectively.
    
    


(This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are damaged after a period of use).
5) It is still another object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose pipe-locking nipples and pipe-locking grooves sequentially lock sequential-locking end joints, sequential-locking middle joints, and sequential-locking pipes of the system together, to withstand repetitive impacts while in use, without falling apart (This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are sagging and falling apart after a period of use).

6) It is still a further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose sequential-locking end joints, sequential-locking middle joints, and sequential-locking pipes can curve in any desired direction and angle for the system to form any desired shape while supporting and protecting a recreational-vehicle sewer hose (This eliminates the problem of the difficulty and inconvenience in assembling, adjusting, and disassembling the cumbersome, time-consuming, difficult-to-operate components of the prior art).

7) It is still an even further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose sequential-locking end joints, sequential-locking middle joints, and sequential-locking pipes can securely function, both right side up and upside down, to support and protect a recreational-vehicle sewer hose, at the same time (This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are sagging and falling apart after a period of use).

8) It is still yet another object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, whose components sequentially lock one another to withstand repetitive impacts while in use, without sagging or falling apart (This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are sagging and falling apart after a period of use).

9) It is still yet a further object of the present invention to provide a new recreational-vehicle sewer-hose-supporting-and-protecting system, which will securely function both right side up and upside down, will not sag over a long distance, and thus will not eventually bend or break over extended periods of use (This eliminates the problem of the reliability and durability of the prior art, their components, or a recreational-vehicle sewer hose, which are sagging and falling apart after a period of use).

Therefore, the new recreational-vehicle sewer-hose-supporting-and-protecting system is quick, easy, convenient, and safe to assemble, adjust, and disassemble for supporting and protecting a recreational-vehicle sewer hose, in a desired shape and at a desired height and angle. As a result, the new recreational-vehicle sewer-hose-supporting-and-protecting system overcomes all the disadvantages of the prior art. These above and additional advantages are described and illustrated in the following examples and illustrations.
