11 Claims. 1

This invention relates to domestic vacuum cleaners and more particularly to-vacuum cleaner handles arranged to serve as a propelling and pick-up handle as well as to aiTord means for supporting a cord take-up reel.

The present invention has for its primary object the provision of an improved handle for domestic, floor-type vacuum cleaners.

Another object of'the invention is ato provide an improved combinationpropelling and pick-up handle for domestic vacuum cleaners.

A still further object of the invention is to provide an improved means for supporting a cord take-up reel in a vacuum cleaner handle.

With the above and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodiment of the invention, from which theseveral features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Fig. l is a plan View of a floor-type vacuum cleaner equipped with the improved handle of this invention and showing the handle assembly lowered to a position substantially parallel to the floor;

Fig. 2 is a side elevational view of the vacuum cleaner shown in Fig. 1;

Fig. 3.is an enlarged bottom .plan view, partly broken away on the line 3--3 of Fig. 2, of a portion of the vacuum cleaner handle and cordreel housing;

Fig. 4 is a side elevational view similar to Fig. 2 but'withthe handle elevated; and

Fig. 5 is an enlarged bottom view of a portion of the handle shown in Figs. 1 and 2.

The vacuum cleaner shown inthe accompanying drawings. has an ambulatory chassis H supported on'a pair of front wheels 12 attached'to the chassis, and a pair of rear wheels l3 attached H which drives a belt l8 and apair of fans (not shown). The belt drives a brush l9 which is rotatably mounted in asuction chamber having a downwardly open mouth 22 through which'dirt The dirt thus colpasses into a dust bag 23; thelower'end'of the "dust bag being detachably connected to the-exhaust outlet I4.

A combination guiding, propelling *and lifting indicated generally by the to an application, Serial No. 784,167, filed November 5, 1947, by Edgar P. Turner.

By reference to Fig. 1, it will be noted that the propelling and pick-up handle assembly 24 is constructed from five portions; viz. a comparatively wide cord-reel housing 28, a transversely extending pick-up handle 29, two longitudinally extending convergent-divergent hollow handle arms or tubes 3| and 32, and a hand-grip 33.

The reel housing 28 has as one of its principal parts an inverted box or half-portion 34. This box carries on its forward, outer facea decorative medallion and a screen 31, the latter being fitted between two spaced rearwardly extending

legs

38 and 39 which are formed integral with the box 34. The screen 31 provides a means for ventilating the interior of the reel housing 28 and'thereby dissipates heat generated by electric current passing through the cord 46 that is wound on a reel 42, carried in the reel housing. The pick-up handle 29 is secured between the rearward ends of the legs 38-49. A bottom cover 4| is secured to and closes the lower open face of the box 34 and thereby encloses the cord-reel 42, and other equipment mounted therein.

Forward or divergent terminals of the tubes 3| and 32 are partly embedded in the rearwardly extending

leg portions

38 and 39 of the box 34 and are held thereto by a U-shaped clamp 43 (Fig. 5). The U-shaped clamp 43 has a main body portion that extends transversely between the extreme forward terminals of the tubes 3|-32 and also has a pair of legs 38 and 39' that extend rearwardly of this main body portion and which are formed complementary to the legs 3839 of the box 34. The rearward or convergent terminals of the tubes 3| and 32 enter and are secured to the comparatively narrow hand-grip 33.

The cord-reel 42, which may be of any well known spring biased construction, is rotatably held to the inner face of the box or half-portion 34 by a fixed axle stud 44, and a two-conductor electric cord is pulled from and retrieved by the reel 42 as necessity requires; the cord being provided with the usual connection plug. It will be noted (Fig. 3) that the cord 45 as it leaves'the reel 42 enters the forward terminal of the tube 3|, passes therethrough and finally exits through a hole provided in a boss 4'! of the hand-grip 33. The forward terminals of the tubes 3| and 32 are so positioned that extensions thereof would be substantially tangent to the periphery of the cord-reel 42. This permits the cord 46 to be unwound from and wound onto the reel without having to pass around sharp bends. For a more complete description of the details of this handle assembly, and especially for a disclosure of one way in which the various parts of the handle may be joined together reference may be had to the application Serial No. 781,836, filed October 24, 1947, by Floyd T. Smith.

As best seen in Fig. 1, it will be noted that the forward or divergent terminals of the handle tubes 3| and 32 are spaced a considerable distance apart and that, as these tubes extend rearwardly toward the hand-grip 33, they converge until their rear terminals at the point where they enter the hand-grip are only about one-half as far apart as are their forward terminals. It will also be noted that the pick-up handle 29 is located substantially one-quarter to one-third of the length of the handle 24 from the pivoted end thereof. With this arrangement, a person, lifting or carrying the cleaner by the pick-up handle 29, lifts the chassis H to a position well above the floor level and at the same time finds that the cleaner is well balanced and easy to carry. The center lines of the two handle tubes 3| and 32, the center line of the pick-up handle 29, the joint between the box 34 and the cover 4|, and the major portion of the meeting line 5| of the hand-grip lie in the same plane. This construction forms a handle which, when it is in the position shown in Fig. 2, is very close to the floor line and therefore makes it easy to manipulate the cleaner and the handle underneath furniture and the like.

In practice, it has been found that a satisfactory handle is obtained when the divergent terminals of the handle tubes are spaced approximately five and one-half or six inches apart at the point where they extend outwardly from the

legs

38 and 39, and wherein the convergent terminals of the tubes are spaced approximately two and one-half to three inches apart at the point where they enter the hand grip 33. The transversely extending pick-up handle 29 extends between the legs 3339 of the box 34, and between the complemental rearwardly extending legs of the clamp 43. This places the pick-up handle 28 between the divergent terminals of the handle tubes 3| and 32 and thus, in the preferred form, the pick-up handle will be. approximately five or six inches long.

The hand-grip 33 comprises an upper shell 48 and a lower shell 49 which join on a surface indicated by the meeting line 5!. The two

shells

48 and 49 are appropriately recessed and thereb encase the rearward terminals of the tubes 35 and 32. A plan view (Fig. 1) of the main por tion of the hand-grip 33 is substantially an isosceles trapezoid, the non-parallel sides of which are parallel to the handle tubes 3i and near their convergent terminals. A grip-portion 52 extends rearwardly and downwardly from the shorter parallel side of the isosceles trapezoida: portion of the hand-grip 33. This grip-portion is substantially in the form of a cylinder and of such size as to be easily grasped by the hand of an operator. The equipment enclosing hand-grip 331s fitted with a number of control I tion to another.

elements including a cord-controlbutton 5 3, an electric switch 54, a pivotally mounted springbiased arm 56 for supporting the upper end of the bag 23, and a latch-control trigger 51 which operates a latch (not shown) for holding the handle in any one of several selected positions. A more complete description of these control elements will be found in the application Serial No. 781,336, referred to above.

A vacuum cleaner equipped with a handle embodying the features of this invention is easy to operate and easy to transport from one loca- If a person wishes to clean a floor covering with the'vacuum cleaner of this invention, he will grasp the grip-portion 52 and thereby propel the vacuum cleaner chassis H back and forth and at the same time guide it to any part of the floor that needs cleaning. If the operator should decide to move the whole vacuum cleaner from one location to another, he grasps the pick-up handle 29 and since this pickup handle is positioned transversely between the longitudinal handle tubes and at a position approximately one-quarter to one-third of the length of the handle from the pivoted end, it will be found to be in the proper and most advantageous position for picking up and carrying the whole vacuum cleaner. Since an extension of the handle tube 3! is tangent to the periphery of the cord-reel 42, a minimum of friction will have to be overcome when the extension cord is pulled from the boss 41 in the hand-grip 33.
