Definitions

  • My invention relates to cord reels for suction cleaners, and is especially concerned with such a cord-carrying structure or carrier for a horizontal tank-type suction cleaher, on which an electric cord may be manually wound when not in use.
  • Another object is to provide such an improved cord carrier which is rigidly mounted on and projects from an end of the tank-type suction cleaner, the cord carrier on which the cord can be manually wound being readily accessible at a region removed from other parts of the suction cleaner so that the cleaner casing will not be cluttered up with the electric cord when not in use, and the handle will always be available for transporting the suction cleaner in a convenient manner.
  • a further object is to provide such an improved nonrotatable cord carrier at one end of a tank-type suction cleaner, on which the cord can be manually wound conveniently with a simple continuous circular motion while the cord is allowed to slip through the hand employed to effect such a circular motion, and from which the cord can be unwound by simply grasping the outer free end thereof and walking from the suction cleaner.
  • Fig. l is an elevation view of a horizontal tank-type suction cleaner provided with a cord-carrying structure or carrier embodying the invention, on which an electric cord may be wound;
  • FIG. 2 is an enlarged fragmentary perspective view of the suction cleaner and cord carrier illustrated in Fig. 1;
  • Fig. 3 is an enlarged perspective view of the cord carrier removed from the suction cleaner shown in Figs. 1 and 2;
  • Fig. 4 is a vertical sectional view of another form of cord carrier for a horizontal tank-type suction cleaner, illustrating a modification of the invention
  • Q Fig. 5 is an end view of still another form of cord carrier for a horizontal tank-type suction cleaner, illustrating another modification of the invention
  • Fig. 6 is a vertical sectional view taken on line 66 of Fig. 5;
  • Fig. 7 is a fragmentary perspective view of a horizontal tank-type suction cleaner provided with a cord of the form shown in Fig. 4, to illustrate another manner of securing the outer free end of the electric cordin place;
  • FIG. 8 is a view which is similar to Fig. 7, and illus- Fig. 11 is a fragmentary perspective view, partly broken away and in section, of the suction cleaner shown in Figs. 1, 2, 7 and 8, to illustrate more clearly the manner in which the cord carriers of Figs. 3, 4 and 6 may be removably secured to the end of a horizontal tank-type cleaner.
  • a horizontal tank-type suction cleaner 10 having a casing 11 which is provided with a handle 12 and runners 14 to facilitate movement thereof on a supporting surface.
  • a front cover 15 is provided for the casing 11 to close an access opening of a space within which a dust bag (not shown) is adapted to be positioned.
  • the cover 15, which is removably secured at 16 to the casing 11, is formed with a central opening 17 to receive one end of a flexible suction hose (not shown) adapted to be removably secured in position in any suitable manner.
  • a rigid hollow tubular member (not shown) is connected to the outer,
  • Suitable cleaning tools such as nozzles or brushes, for example, are connected to the hollow tubular member or directly to the suction hose, depending upon the nature of thecleaning operation to be performed
  • a motor-fan unit (not shown) which is manually controlled by a switch having an operating button 18. Dust laden air is drawn into the interior of the casing 11 through the central opening 17 in the cover 15. Dust collects in the dust bag during a cleaning operation, and air free of such dust passes through the dust bag and flows through the casing 11 and is eventually discharged by' the motor-fan unit through an end opening 19 in a rear hood 20.
  • the rear hood 20 is provided with a rectangular-shaped opening 21 which is closed by an end plate 22 having a hollow sleeve 23 extending inwardly therefrom which forms the discharge opening 19.
  • the plate 22 is formed .with a plug 31 adapted to be inserted in an outlet socket of a source of electrical energy.
  • I provide a carrier or carrying structure for the electric cord 30, which is mounted at an end of the suction cleaner 10 and projects r itherefrom in the lengthwise direction of the casing 11.
  • the carrier 32 comprises an open frame having spaced-apart circular members 33 and 34, and connecting members 35 which are curved and extend radially outward from the small endto thelarge end ofthe carrier.
  • the connecting members are convex-shaped and have openings 36 therebetween.
  • the circular member 33 at the small end of the carrier 32 is provided with an externally threaded flange 37 which isv adapted to be threadedly connected to the internally threaded peripheral wall or shoulder 27 of the recess 26 in the plate 22.
  • the turns of the cord initially wound on the carrier define a truncated pyramid.
  • Each turn of the cord at-the immediatevicinity of the connecting members 35 is of rectangular form, the turns adjacent the circular member 34 being of larger cross-section than those adjacent the circular member 33.
  • the cord 30 when the cord 30 is wound in its entirety on the carrier 32, in external appearance the cord is more or less in the form of a cylindrical-shaped coil, with the end wall of the rear cover 20 serving as one outwardly extending side of "a non-rotatable spool or'holder for the cord, and the carrier itself serving as an axially extending hollow sleeve-like portion and also the other side of the spool or holder which also extends radially outward from the hollow sleeve-like portion. Since the end wall of the rear cover 20 serves as one outwardly extending side of the spool or cord-carrying structure, it may be stated that the one outwardly extending side at the end wall is substantially in the plane of such e'ndwall.
  • Fig. 4 illustrates another embodiment of the invention, in which the carrier 32a is formed with a threaded tubular section 37a for mounting the carrier on the suction cleaner 10.
  • the carrier 32a which is bell-shaped or funnelshaped, and flares outward from the small to the large end thereof, is imperforate and formed with a hollow bead 34a at its extreme outer end when mounted on the cleaner 10.
  • Figs. 5 and 6 illustrate a further embodiment of the invention, in which the carrier 32b is also provided with a threaded tubular section 37b for mounting the carrier on the cleaner 10.
  • the carrier 32b is also bell-shaped or funnel-shaped, and differs from the embodiment of Fig. 4 in that it is formed with a number of openings or apertures 36b.
  • the carriers 32, 32a and 32b are threadedly connected to an end of the cleaner 10, the carriers are rigidly mounted on the rear hood or endcover 20 and form a unitary and stationary part of the cleaner. Hence, the carriers 32, 32a and 32b extend or project from the main body portion of the suction cleaner and are secured thereto more or less in cantilever fashion.
  • a generally spool-shaped cord-carrying structure having a hollow center portion and end portions at opposite ends of the center portion extending transversely of and radially outward from the center portion.
  • the annular region 27 of the end wall plate 22 forms a surface engagingpart of annular form which encircles the axis of the exhaust port 19 and is of larger diameter than the exhaust port.
  • the section of the cleaner end wall extending outwardly from the annular region 27 serves as onerof the end portions of the cord-carrying structure.
  • the hollow center portion and opposite end portion of the cord-carrying structure are formed by the hollow reel sections 32, 32a and 32b in the manner i-llus tr'ated in Figs. 2, 7 and ,8.
  • the cord normally extends lengthwise of the cleaner from the recessed bottom portion 29 thereof when the cleaner is being used.
  • the cord 30 can readily be wound on the carriers 32, 32a and 32b because the carriers project from an end of the suction cleaner 10 and are removed from other parts thereof, so that the need for manipulating and guiding the cord through and around a number of parts of the cleaner in a particular path of movement is absent.
  • the cord 30 With the 'cord 30 wound on the carriers 32, 32a or 32b and the suction cleaner 10 in a horizontal position, as shown in Figs. 2, 7 and 8, the cord 30 can be manually unwound without difilculty to connect the plug 31 to an outlet socket.
  • the cord 30 When it is desired to operate the cleaner, it is only necessary to grasp the plug 31 and walk from the cleaner 10 in a direction more or less in alignment with the casing 11. In this way, successive turns of the cord readily slip off the large end of the carrier, so that the cord can be unwound in a continuous manner and without the need to stoop down beside the cleaner and unwind the cord in a piecemeal fashion.
  • one end of a suction hose 9 may be removably secured in position in any suitable manner to the discharge opening 19 in the rear hood 20, as shown in Fig. 8. In this way, a strong blast of air is discharged from the cleaner through the suction hose to the atomizer or sprayer which is connected to the outer free end of the hose. Since the diameter of the discharge opening .19 in the rear.
  • the suction cleaner 10 can be used for a spraying or atomizing operation, or for any other purpose requiring a positive blast of air, without the necessity of first removing the carriers 32, 32a or 32b.
  • the reels can remain on thecleaner at all times irrespective of whether the suction hose is connected to the front cover 15 or rear hood 20 of the cleaner. As seen in Figs.
  • the smaller end of the hollow reel section 32a, at the region it is joined to the threaded surface engaging part 27, is spaced radially from the exhaust port 19 .to form a passage through the hollow reel section large enough for the hose 9 to be inserted therethrough and connected to the exhaust port 19.
  • the cordcarriers 32 and 32b may also be effectively used as a supporting base for the cleaner 10 when it is desired to maintain the cleaner in an upright position during a cleaning operation, as shown in Fig. 1.
  • the suction hose would be connected to the opeiing 17 in'the front cover 15 in such cleaning operation. Since the carriers 32 and 32b are formed with openings or apertures 36 and 36b, respectively, the air discharged from the opening 19 in the rear hood or cover 20 can readily pass therefrom into the atmosphere, whichwould not be true if the carrier 32a, which is imperforate, were used as a supporting base for the cleaner in the manner shown in Fig. l. v
  • the plug 31 at the outer free end of the cord may be fastened in position in any suitable manner.
  • the outer free end portion 38 of the cord, to which the plug 31 is secured may be tightly held in place between the circular member 34 and a turn 39 of the coil immediately adjacent the circular member 34.
  • the portion 38 of the cord is pushed radially inward underneath the circular member 34, sothat plug 31 will be positioned within the circular member at the large end of the reel.
  • Fig. '7 the outer free end portion of the cord 30 is bent' back upon itself to form a loop 40' which is drawn underneath a turn 41 of the coil. After the loop 41' is in the position illustrated in Fig. 7, such loop can be tightly drawn in place to clamp it between the turn 41 and other turns of the coil beneath it.
  • a holder 42 is employed to hold the outer free end portion 43 of the cord 30 in place.
  • the holder 42 comprises cooperating parts 43a and 44 removably secured together at 45.
  • a ring-shaped end 46 is formed at one end of the holder in which the outer free portion 43 of the cord is clamped.
  • a recessed part 47 is provided at the opposite end of the holder 42 to receive a region of the cord 30.
  • the gap 48 between the spaced apart arms 49, through which the cord passes when inserted into the recess 47 and withdrawn therefrom, is slightly smaller in size than the cord, so that the region of the cord held in the recess 47 is held fairly securely in place.
  • the outer free end portion 43 of the cord is securely held in the ring-shaped end 46 of the holder 43.
  • one of the turns 50 is inserted in the recess 47 of the holder through the gap 48.
  • the holder 42 is moved from the coil turn 50 to cause the latter to move out of the recess 47 and release the outer free end portion 43 of the cord.
  • an improved carrier has been provided for a horizontal tank-type suction cleaner, which is simple and extremely convenient for manually winding and unwinding an electric cord thereon and therefrom.
  • a compact arrangement is provided which occupies a minimum amount of space.
  • the electric cord is readily accessible at a region removed from other parts of the cleaner, and the main body portion of the cleaner will not be cluttered up with the electric cord, so that the handle will always be available for transporting the cleaner in a convenient manner.
  • the carriers 32, 32a and 32b may be formed integrally with end plate 22 or rear hood or cover 20, the small ends of the carriers in such case being of larger diameter than the discharge opening 19 at the rear end of the cleaner. Therefore, I intend in the following claims to cover all modifications which do not depart from the spirit and scope of my invention.
