A motor is coupled to the housing and selectively engages the reel wherein the reel is rotated by the motor retracting the hose onto the reel when the motor is actuated.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
An aperture 32 extends through the housing 12 and may more particularly extend through the perimeter wall 16 of the housing 12. A reel 34 is coupled to the housing 12 and positioned in the interior space 18 of the housing 12 proximate the aperture 32. A hose 36 has a first end 38 coupled to the reel 34. The hose 36 is extended around the reel 34 wherein a second end 40 of the hose 36 is selectively extendable from the reel 34 through the aperture 32 in the housing 12. Each of a plurality of rollers 42 may be coupled to the housing 12. Each roller 42 may be elongated and substantially cylindrical. The rollers 42 are arranged coextensive with edges 44 of the aperture 32 wherein the rollers 42 reduce friction between the edges 44 of the aperture 32 and the hose 36 when the hose 36 contacts the edges 44 of the aperture 32.
An oxygen port 46 is coupled to the housing 12. The oxygen port 46 is configured for coupling to an oxygen source, such as an oxygen tank, by way of tubing or the like. Thus, oxygen is delivered through the oxygen port 46. The oxygen port 46 is in fluid communication with the hose 36 wherein the hose 36 is configured for receiving oxygen into the hose 36 and dispensing oxygen through the second end 40 of the hose 36. The second end 40 of the hose 36 may be coupled to a conventional mask or outlet positionable adjacent to or in one of more nostrils of a person requiring or desiring supplemental oxygen. The oxygen port 46 may extend through the bottom wall 14 of the housing 12. The oxygen port 46 may include a circumferentially notched distal extent 82 designed to engage the tubing from the oxygen source. A panel 84 having a rectangular shape may be incorporated into the oxygen port 46 coplanar with the bottom wall 14 to prevent rotation of the oxygen port 46 relative to the bottom wall 14. Fluid communication between the oxygen port 46 and the first end 38 of the hose 36 coupled to the reel 34 may be provided in a conventional manner such that rotation of the reel 34 is not restricted.
A motor 48 is coupled to the housing 12. The motor 48 is selectively engageable to the reel 34 wherein the reel 34 is rotated by the motor 48 to retract the hose 36 onto the reel 34 when the motor 48 is actuated. Thus, the assembly 10 allows for use of a hose 36 have a long length permitting the person to move freely without having to also carry or transport the oxygen source. Retraction of the hose 36 onto the reel 34 prevents the hose 36 from tripping the person, snagging on objects, or the like, while the person remains in closer proximity to the housing 12 and oxygen source.
A tension mechanism 50 is coupled to the housing 12. The motor 48 is coupled to the tension mechanism 50. The tension mechanism 50 adjustably urges the motor 48 into abutment with the reel 34 wherein frictional engagement between the motor 48 and the reel 34 is adjusted by the tension mechanism 50. The tension mechanism 50 may comprise a post 52. The motor 48 is slidably coupled to the post 52 by way of a harness or seat 54 positioned proximate a first end 56 of the post 52. A wing nut 58 or similar screw type block is coupled to the post 52 by threading 60. The wing nut 58 is selectively positionable along a length of the post 52 a selectable distance from the first end 56 of the post 52. A biasing member 62 is coupled to the post 52 extending between the wing nut 58 and the motor 48 such that adjustment of the wing nut 58 along the post 52 compresses or expands the biasing member 62 to vary resistance to sliding of the motor 48 relative to the post 52. A frictional layer 64 or band may be coupled to a perimeter of the reel 34 to be contacted by the motor 48 facilitating frictional engagement of the motor 48 to the reel 34. The tension mechanism 50 may be set to allow slippage between the motor 48 and the reel 34 such that the motor 48 is prevented from rotating the reel 34 when the hose 36 exerts resistance to being retracted beyond a desired threshold. The threshold may be set sufficiently low that the motor 48 will not forcefully detach the second end 40 of the hose 36 from a user, pull the user over, pull the housing 12 over, or the like. A tension arm 66 has a first end 68 pivotally coupled to the housing 12. The tension mechanism 50 may be coupled to the tension arm 66. A piston 70 is coupled to the housing 12 and the tension arm 66. The piston 70 selectively pivots the tension arm 66 between a first position 72 and a second position 74. The motor 48 engages the reel 34 in the first position 72 and the motor 48 is disengaged from the reel 34 in the second position 74 wherein the motor 48 is selectively engaged to and disengaged from the reel 34 by the piston 70.
A remote control 76 may be provided and carried by a person using the assembly 10 to provide oxygen. The remote control 76 is communicatively coupled to the motor 48 wherein the motor 48 is selectively activated by operation of the remote control 76. The remote control 76 may include an activation button 78 which causes the piston 70 to engage the motor 48 to the reel 34 while the motor 48 is activated.
Protection from excessive wear on the motor 48 or the abutting surface of the motor 48 and the reel 34 may be provided. A motion detector 80 may be coupled to and positioned in the housing 12 monitoring rotation of the reel 34. The motion detector 80 is communicatively coupled to the motor 48 and the piston 70 wherein the piston 70 disengages the motor 48 from the reel 34 upon the motion detector 80 detecting a lack of rotation of the reel 34 while the motor 48 is activated. A first time delay mechanism 86 is operationally coupled to the motor 48 such that the motor 48 is prevented from being deactivated during an initial period of time when the motor 48 is first actuated. The initial period of time may be determined by a duration of time equivalent to permit one full rotation of the reel 34 while the motor 48 is actuated. A second time delay mechanism 88 is operationally coupled to the motor 48 in combination with the first time delay mechanism 86. Each may be a form of relay in circuit with the motor 48 and piston 70 such that closing of the circuit through either of the first time delay mechanism 86 or the second time delay mechanism 88 is required to deactivate the motor 48. The motion detector 80 may be operationally coupled to the second time delay mechanism 88 such that the motor 48 is prevented from being deactivated for a pre-determined time increment when the motion detector 80 detects continuing movement of the reel 34. The pre-determined time increment may be a duration of time equivalent to one half rotation of the reel 34 while the motor 48 is actuated. The second time delay mechanism 88 is automatically reset upon expiration of each pre-determined time increment when the motion detector 80 detects continued motion at the expiration of an immediately prior time increment. Thus, the motor 48 will continue to retract the hose 36 onto the reel 34 so long as the motion detector 80 detects continued motion of the reel 34.
In use, the assembly 10 allows for free extension of the hose 36 from the housing 12 through the aperture 32 permitting a user to move an extended distance from the housing 12. When returning to a position near the housing 12, the remote control 76 may be manipulated to engage the motor 48 to the reel 34, retracting the hose 36 into the housing 12. Frictional engagement of the motor 48 to the reel 34 is adjustable to permit slippage of the motor 48 relative to the reel 34 when excess tension is present in the hose 36. Automatic deactivation of the motor 48 is provided for as described above when the reel stops moving due to excess tension in the hose 36, which may be from snagging or full retraction of the hose 36.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
