Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to hose locks, and more particularly to hose locks for wet/dry vacuum cleaners requiring a sealed connection to prevent leakage.




2. Description of Related Art




Vacuum appliances capable of picking up both wet and dry material, commonly referred to as wet/dry vacuums or wet/dry vacs, are often used in workshops and other environments where both wet and dry debris can accumulate. Wet/dry vacs conventionally consist of a collection tank or canister, sometimes mounted on wheels or casters, and a powerhead within which a motor and impeller assembly is mounted. The motor and impeller assembly creates suction within the canister, such that debris and/or liquid is drawn in to the canister through an air inlet to which a flexible hose can be attached. A filter within the canister prevents incoming debris from escaping from the canister while allowing filtered air to escape. Any liquid drawn into the canister is diffused and accumulates on the bottom of the canister.




With known wet/dry vacs, the hose is typically attached to the air inlet via a friction fit. Ordinarily, the connection end of the hose is tapered, and the tapered end is simply inserted into the air inlet until the two parts mate. The friction between the hose and the air inlet is relied upon to hold the hose in place. It is important to have a sealed connection between the hose and the air inlet, because any air leaks thereabout reduce the suction through the hose, degrading performance. Unfortunately, Wet/dry vacs employing a hose connection using a purely friction fit often have problems with the hose connection leaking, or inadvertently disconnecting.




One common attempted remedy for this problem is to insert the end of the hose into the air inlet forcefully, such that the hose end is mated very tightly with the air inlet. However, this type of connection is often unsatisfactory for users, since it is difficult to discern whether the connection is tight enough to prevent leaks and disconnections. Further, if the hose end is mated with the air inlet tightly enough to provide a sealed connection and prevent inadvertent disconnections, the hose often becomes difficult to remove.




Another attempted solution uses a locking member to positively couple the hose to the air inlet. This is also not without problems. With purely friction fit, manufacturing tolerances for the tapered hose end are typically relaxed, since the tapered end is inserted until it mates with the air inlet. However, if a locking member is added to lock the hose to the air inlet, manufacturing tolerances become significantly more critical. If placement of the locking member is off in one direction, the tapered end of the hose may not mate with the air inlet when the lock is engaged. On the other hand, if placement of the locking member is off in the opposite direction, friction between the tapered end of the hose and the air inlet may prevent inserting the hose end far enough to allow the locking member to engage. Tightening tolerances such that the tapered hose end mates with the air inlet in a sealed manner, while allowing the locking member to positively lock the hose in place can significantly increase design and manufacturing costs.




Thus, there remains a need for a hose lock that is quick and easy to lock and unlock with a secure connection that prevents leakage. The present invention provides for a hose lock that addresses shortcomings associated with the prior art.




SUMMARY OF THE INVENTION




In one aspect of the present invention, a device for connecting a hose to a wet/dry vacuum includes a first member having first and second ends, with the first end adapted to be coupled to the hose. A receptacle has first and second ends. The first end of the receptacle is adapted to be mounted to the article, and the second end is adapted to be connected to the second end of the first member. A locking member is mounted on one of the first member or the receptacle for securing the first member to the receptacle, and at least one sealing member is situated about one of the second end of the first member or the second end of the receptacle. In one embodiment, the sealing member is integrally formed with the first member and is adapted to seal against an external surface of the receptacle. In another embodiment, the sealing member comprises a sealing ring removably mounted on the first member or the receptacle.




An alternative embodiment of this invention is an adapter for adapting a friction-based vacuum connection receptacle, as disclosed in the prior art, such that that it can be used with the hose-locking mechanism of this invention. The adapter has first and second ends. A first end is constructed such that the adapter can be affixed to the friction-based connecting receptacle of a vacuum. A second end of the adapter is constructed so as to be able to connect to a first member, (such as on the end of a hose) having a locking member, as described above.




In another aspect of the present invention a wet/dry vac includes a collection tub, a lid coupled to the collection tub and a powerhead assembly operable to create suction within the collection tub. An inlet port is disposed in one of the lid or the collection tub and a receptacle is coupled to the inlet port. A connection member has first and second ends, with the first end adapted to be coupled to the hose. At least one sealing member is mounted on at least one of the receptacle and the first end of the connection member. The sealing member may be integrally formed with the receptacle or the connection member, or the sealing member may comprise a sealing ring that is removably mounted to the connection member or the receptacle. A locking member is provided for securing the connection member to the receptacle member. In one embodiment, the sealing member seals with an external surface of the receptacle. In another embodiment, the sealing member seals with an internal surface of the receptacle in addition to, or in place of, the external seal.

DETAILED DESCRIPTION OF THE INVENTION




Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.




Turning to the figures,

FIG. 1

shows a perspective view of an embodiment of a hose lock according to the present invention employed on a wet/dry vac


1


. As will be appreciated by one skilled in the art with the benefit of this disclosure, the hose lock can be utilized on any application requiring a leak-free seal and a quick connect/disconnect mechanism. As shown in

FIG. 1

, the wet/dry vac


1


comprises a collection tub


2


having a lid


3


and a powerhead assembly


4


. The collection tub


2


and the lid


3


are preferably made of injection-molded plastic, such as polypropylene or the like, in accordance with conventional practice.




In accordance with conventional designs, an air inlet port


5


is defined in the lid


3


or, alternatively, may be defined in a side wall of the collection tub


2


. The powerhead assembly


4


houses a motor and impeller assembly, and has defined therein an air exhaust or outlet port


6


. A hose connection member


10


is locked onto a receptacle


150


that is mounted on the inlet port


5


of the wet/dry vac


1


to attach a hose


202


to the wet/dry vac


1


. A locking handle


100


positively locks the connection member


10


to the wet/dry vac


1


. The connecting receptacle


150


can be removably mounted to the wet/dry vac


1


, or can be an integral part of it. The powerhead assembly


4


is operable to create a suction within the collection tub


2


, such that debris and/or liquid is drawn in to the collection tub


2


through the hose


202


, which is attached to the inlet port


5


via the connecting receptacle


150


and connection member


10


.





FIG. 2

shows a perspective view of an embodiment of the hose connection member


10


in accordance with the present invention. The hose connection member


10


, may be made of plastic. The hose connection member


10


has a hose end


40


, a main body


80


, and a vac end


50


. In the particular embodiment illustrated in

FIG. 2

, the vac end


50


has a larger outside diameter than the main body


80


, and is adapted to have one or more sealing members removably mounted thereto. The inside diameter of the vac end


50


and the main body


80


is roughly uniform. The vac end


50


of the hose connection member


10


defines a groove


30


, which is adapted to have seated therein the sealing member, which, in the embodiment illustrated in

FIG. 2

, comprises an O-ring


20


.




To allow the insertion of the vac end


50


of the hose connection member


10


into the receptacle


150


(not shown in

FIG. 2

) to achieve a sealed connection, the diameter of the receptacle


150


should exceed that of the vac end


50


, and the O-ring


20


should extend above the surface of the vac end


50


, so that the O-ring


20


seals against an internal surface of the receptacle


150


. In the embodiment illustrated in

FIG. 2

, the hose end


40


has a smaller circumference than the main body


80


of the hose connection member


10


. The hose end


40


has a ridge


60


extending over and around the surface of the hose connection member


10


as shown in FIG.


2


.

FIG. 7

shows how the ridge


60


permits rotating and swiveling a hose


202


situated over the hose end


40


and maintains the hose


202


attached to the hose connection member


10


. The hose end


40


also has a hose stopper


70


to prevent the hose


202


from sliding further over the hose connection member


10


as shown in FIG.


7


.




In an alternative embodiment, as shown in

FIG. 10

, O-ring


20


may be replaced by a seal member integrally formed in the vac end


50


. Such an integrally formed seal member would have a diameter generally greater than the diameter of the vac end


50


so as to form a friction seal with an internal surface of the receptacle


150


when the vac end


50


is inserted therein. Moreover, the seal member may have a diameter greater than the inside diameter of the receptacle


150


and be formed in a manner to allow the seal member to deflect when the vac end


50


is inserted into the receptacle


150


.




An embodiment of the hose connection member


10


having an alternative configuration of the vac end


50


is illustrated in

FIG. 3

, in a plan view. In the embodiment illustrated in

FIG. 3

, the vac end


50


defines a plurality of grooves


31


therein, and a sealing ring


21


extends around the vac end


50


.

FIG. 4

is a partial section view of the vac end


50


of the hose connection member


40


inserted into the receptacle


150


. The sealing ring


21


defines a sealing surface


22


that is generally perpendicular to the axis of the connection member


10


. The sealing ring


21


is formed such that, when the vac end


50


is inserted into the receptacle


150


, the sealing surface


22


abuts an external surface of the receptacle


150


. When the wet/dry vac


1


is operated such that the power head assembly


4


creates a suction within the tub


2


, the hose connection member


10


is sucked against the receptacle


150


, causing the sealing surface


22


of the sealing ring


21


to seal against the external surface of the receptacle


150


. This “self seal” prevents air from entering the tub


2


other than through the hose and hose connection member


10


.




In alternative embodiments, one or more O-rings


20


, as illustrated in

FIG. 2

, may be seated in one or more of the grooves


31


to provide an internal, friction seal in addition to the external seal formed by the sealing surface


22


of the sealing ring


21


.




The hose connection member


10


defines a U-shaped channel


90


as shown in FIG.


2


and FIG.


3


.

FIG. 5

shows a side view of the locking handle


100


made to fit the U-shaped channel


90


shown in FIG.


2


and FIG.


3


. The locking handle may be suitably made of hard sturdy material, such as plastic. The locking handle


100


has a pivot


110


that fits within two spring chambers


92


on the U-shaped channel


90


. The locking handle


100


is pivotally attached to the connection member


10


by the spring chambers


92


holding the pivot


110


. The locking handle


100


has a single tooth


140


to lock onto a connecting receptacle on the vac end


50


of the hose connection member


10


. The locking handle


100


also has a pressing surface


120


having grip indentations


130


to prevent slippage when the pressing surface


120


is pushed, and a spring lever


115


extends below the pressing surface


120


. When the locking handle


115


is pivotally attached to the connection member


10


, the spring lever


115


presses against the connection member


10


to bias the tooth


140


down against the connection member


10


.





FIG. 6

shows an exemplary embodiment of one end of the connecting receptacle


150


that is adapted to have the vac end


50


of the connection member


10


inserted therein. The receptacle


150


has a U-shaped casing


160


to receive the locking handle


100


on the vac end


50


of the hose connection member


10


. The U-shaped casing


160


has a single post


170


traversing it. The tooth


140


on the locking handle


100


is made to interlock with the post


170


. Alternatively, a groove or indentation may be used to interlock with the tooth


140


on the locking handle


100


. As will be appreciated by one skilled in the art having the benefit of this disclosure an alternative embodiment can have the locking handle


100


attached to the connecting receptacle


150


, and the U-shaped casing


160


and post


170


located on the hose connection member


10


.





FIG. 4

illustrates the manner by which the locking lever


100


couples the hose connection member


50


to the receptacle


150


. To reach the illustrated position, the vac end


50


of the hose connection member


10


is inserted inside the connecting receptacle


150


. As the vac end


50


is inserted in the connecting receptacle


150


, the pressing surface


120


on the locking handle


100


is pressed to lift the single tooth


140


and permit insertion of the locking handle


100


end into the U-shaped casing


160


. Once the vac end


50


is inserted in the connecting receptacle


150


, the pressing surface


120


is released, and the spring lever


115


pushes the tooth


140


down, allowing the single tooth


140


to lock onto the post


170


traversing the U-shaped casing


160


as shown in FIG.


4


. This action forms a positive lock between the hose connection member


10


and the connecting receptacle


150


, preventing unwanted disconnections.




The embodiments of the vac end


50


disclosed herein allow for manufacturing variation in the placement of the various parts (the locking handle


100


, the post


170


, the tooth


140


, etc.) involved in locking and sealing the connection member


10


to the receptacle


150


. The locking handle


100


keeps the connection together and prevents accidental disconnection, while the sealing ring


21


self seals against the outer surface of the receptacle


150


when the wet/dry vac is operated to prevent leakage. Thus, it is not necessary for the vac end


50


to mate with the inside of the receptacle


150


to form a friction or interference seal.




In embodiments employing one or more O-rings


20


(as illustrated in FIG.


2


), the O-ring


20


would interact with the inner surface of the receptacle


150


to provide a sealed connection, rather than relying on a direct friction seal between the vac end


50


and the inside of the receptacle


150


. Further, the O-ring


20


is not required to interact with any particular location along the inside surface of the receptacle


150


.




As will be appreciated by one skilled in the art having the benefit of this disclosure, the sealing ring


20


shown in

FIG. 2

may be positioned in alternative locations. For example, the O-ring


20


may be mounted within the inner wall of the vac end


50


of the connection member


10


. In this case, the connecting receptacle


150


will be of a smaller diameter than the vac end


50


of the connection member


10


. Alternatively, the O-ring


20


may be mounted on the connecting receptacle


150


rather than on the connection member


10


.




As shown in

FIG. 7

, according to one embodiment of the invention, the hose end


40


of the hose connection member


10


is inserted inside a hose


202


. The hose


202


is generally flexible and composed of sequential rings


204


with alternating diameters at the connecting end. The ridge


60


on the hose end


40


of the hose connection member


10


locks onto one of the sequential rings


204


on the hose


202


to prevent the hose connection member


10


from slipping out of the hose


202


. The hose connection member


10


is prevented from further entering into the hose


202


by a decrease in hose


202


diameter as shown in FIG.


7


.





FIG. 8

shows a perspective view of an alternative embodiment of the present invention. The exemplary embodiment of

FIG. 8

differs from the embodiment disclosed in conjunction with

FIGS. 2-6

with respect to the locking mechanism. According to the embodiment of

FIG. 8

, a connecting handle


180


, having a circular orifice


190


, a grooved press base


200


, and a cusp


210


, is placed inside the main body


80


of the hose connection member


10


. The main body


80


of the hose connection member


10


has an aperture


220


from where the grooved press base


200


can protrude and extend above the surface of the main body


80


of the hose connection member


10


. The connecting handle


180


is attached to the main body


80


of the connection member


10


by inserting a pin


230


through a perforation


240


on the main body


80


and through the circular orifice


190


on the connecting handle


180


. The connecting handle


180


should be long enough for the cusp


210


to extend past the end of the seal side


50


of the hose connection member


10


.




According to the embodiment of

FIG. 8

, the connecting receptacle


150


has an elevated housing


250


adapted to receive the cusp


210


on the connecting handle


180


. The elevated housing


250


also defines a recess


260


to interlock with the cusp


210


on the connecting handle


180


. The hose end


40


is essentially the same in both embodiments described. The sealing ring


20


is seated over the groove


30


on the vac end


50


as in the embodiment.





FIG. 9

shows a perspective view of a hose connection member


10


connected to the connecting receptacle


150


according to the embodiment of FIG.


8


. When the hose connection member


10


is connected to the connecting receptacle


150


as shown in

FIG. 9

, the seal ring


20


seated on the groove


30


on the hose connection member


10


, makes an interference fit with the inner walls of the connecting receptacle


150


. To lock the connection the grooved press base


200


on the connecting handle


180


is pressed as the seal end


50


of the hose connection member


10


is slipped into the connecting receptacle


150


. The cusp


210


should be aligned with the elevated housing


250


. Once the cusp


210


is below the recess


260


in the elevated housing


250


, and the pressure is released from the grooved press base


200


, the cusp


210


interlocks with the recess


260


.





FIG. 10

shows a perspective view of another alternative embodiment of the present invention. The exemplary embodiment of

FIG. 10

differs from the embodiment disclosed in conjunction with

FIGS. 2-9

with respect to the sealing member. According to the embodiment of

FIG. 10

, a connection member


10


is shown having a first end


300


and second end


310


. First end


300


has depression


320


around its outer surface, and a thin, annular rib


330


integrally formed around connection member


10


inside of depression


320


. Rib


330


protrudes outward from depression


320


such that it extends slightly beyond the surface of connection member


10


. A magnified view of this is shown in FIG.


11


.




According to this embodiment, connection member


10


is inserted into receptacle


150


while creating a proper seal, without the need for a separate sealing member such as an O-ring. When connection member


10


is inserted into receptacle


150


, rib


330


is bent backward by its contact with the inner surface of receptacle


150


such that a proper seal is formed. Depression


320


, in which rib


330


is set, provides clearance for rib


330


to flex when inserted into receptacle


150


. Thus, rib


330


is deformed by the inner surface of receptacle


150


, forming a self-energizing seal when a vacuum is created inside of the vacuum cleaner. The configuration can also be reversed, with rib


330


being integrally formed into the inner surface of receptacle


150


and a seal created when connection member


10


is inserted into receptacle


150


.




Rib


330


is preferably constructed from a polypropylene material, although other materials can be used which have a suitable flexural modulus to allow a proper seal to be maintained, and which allow rib


330


to return to its original shape when disengaged from receptacle


150


. This embodiment of the connecting member, having an integrated sealing member, has several benefits. First, this embodiment provides a one-piece construction of a connection member, which is easier to handle and work with than a multi-piece assembly. Secondly, cost savings can be realized by integrating the function of separate parts into a single molded part.





FIG. 12

shows a perspective view of another embodiment of the invention, adapter


400


, which can be used to permanently convert a wet/dry vacuum having a friction-based hose connecting receptacle


490


(as used in the prior art, and shown in

FIG. 14

) to a vacuum able to receive a hose having a locking attachment, as disclosed herein. Adapter


400


has two ends, a connecting end


410


and an adapting end


420


. Connecting end


410


has a U-shaped casing


430


to receive the locking handle


100


on the vacuum end


50


of connection member


10


(not shown). The U-shaped casing


430


has a single post


470


traversing it. The tooth


140


on the locking handle


100


of connection member


10


is made to interlock with the post


470


. Alternatively, a groove or indentation may be used to interlock with the tooth


140


on the locking handle


100


. As will be appreciated by one skilled in the art having the benefit of this disclosure, an alternative embodiment of adapter


400


can have the locking handle


100


attached to the connecting end


410


of the adapter


400


, with the U-shaped casing


160


and post


170


located on the connection member


10


. Also, the locking mechanisms need not be of the particular configuration disclosed herein.




Adapting end


420


of adapter


400


, also shown in

FIG. 13

, is configured so as to permanently lock adapter


100


into place onto a friction-based vacuum connecting receptacle


490


. Flaps


440


at the end of adapting side


420


operate to latch adapter


400


onto the end of a friction-based vacuum connecting receptacle


490


when adapting side


420


of adapter


400


is inserted into the connecting receptacle. This thus gives a consumer the advantage of upgrading an older, friction-fit wet/dry vacuum without the expense of purchasing a new unit having a hose lock feature as disclosed herein.




Adapter


400


may be made of plastic, and may be designed to fit all embodiments of receptacle


150


. One skilled in the art having the benefit of this disclosure will appreciate that an alternative embodiment of adapter


400


can be configured to attach to the vacuum end of a friction based hose connection member such that a friction-based hose can be adapted for use with a wet/dry vacuum having a locking attachment as disclosed herein.




Thus, the present invention provides a hose lock, and adapter, that quickly and simply locks a hose to a receptacle mounted on an article such as a wet/dry vac to prevent inadvertent disconnections, while providing a seal to prevent air leaks.
