Toy HOOPS Filed Jan. 9, 1969 INVENTOR. P E 2 ROBERT E. SMITH ATTORNEY United States Patent 3,523,387 TOY HOOPS Robert Eugene Smith, Box 1108, Denver, Colo. 80201 Filed Jan. 9, 1969, Ser. No. 790,111
. Int. Cl. A63h /00 US. CI. 46-52 4 Claims ABSTRACT OF THE DISCLOSURE A toy hoop having a hollow body with spaced air inlet and outlet openings and an air restrictor inbetween which produce one whistling sound when the hoop is rotated in one direction and a dilferent sound when it is rotated in the opposite direction.
This invention relates to new and useful improvements in toy hoops, and has particular reference to that class of toy hoops commonly known as hula hoops, of which the most common usage is to place such a hoop in a generally horizontal plane encircling the waist of the user, and to maintain said hoop in a whirling motion about the body by orbital or gyrating movements of the torso. Such hoops have been extremely popular and are in wide usage at the present time.
The principal object of the present invention is the provision of a toy hoop of the type described having novel means associated therewith whereby a whistling noise is emitted as the hoop is spun about the body in its normal mode of usage.
Another object is the provision of a toy hoop of the general character described formed of tubular stock, and wherein the whistling means is confined substantially entirely within the tubular confines of the stock, whereby said whistling means does not appreciably alter its configuration, appearance, or operation.
Still another object is the provision of means for adjusting the pitch of the note emitted by the whistling means.
Other objects are extreme simplicity and economy of construction, efliciency and dependability of operation, and adaptability for application to existing toy hoops of the character described.
With these objects in view, as well as other objects which will appear in the course of the specification, reference will 'be had to the drawing, wherein:
FIG. 1 is a plan or face view of a toy hoop embodying the present invention.
FIG. 2 is an enlarged fragmentary central sectional view of the hoop taken in the plane of the hoop.
FIG. 3 is an enlarged layout view of a portion of the hoop.
FIG. 4 is an enlarged external lay-out view of the portion of the hoop shown in FIG. 3, and
FIGS. 5 and 6 are enlarged, enlongated sectional views taken respectively on lines V-V and VI--VI of FIG. 2.
Like reference numerals apply to similar parts throughout the several views, and the numeral 2 applies to a hoop of the character described, commonly known as a hula hoop. It comprises a length of tubular material, usually but not necessarily a light weight, semi-rigid plastic, formed into a circular hoop.
A plurality of whistling means are incorporated in the tube comprising the hoop, at spaced intervals therealong. As best shown, each of said whistling means includes an air inlet opening 6 formed in the inner peripheral wall of the tube, tube wall at the leading edge of said opening, when the hoop is rotated in the direction of arrow 8 being formed to present an inturned lip 10, and the tube wall at the trailing edge of said opening, being formed to pre- 3,523,387 Patented Aug. 11, 1970 "ice sent an outtumed lip 12, so as to facilitate the entry of air to an air receiving chamber 14 within the tube when the hoop is rotated in the direction of arrow 8. The extension of lip 12 outwardly from the normal cirular contour of the tube is small, however, and does not interfere with normal usage of the hoop.
Thus when the hoop is placed around the torso or other portion of the body of a person, and the torso or other body portion is gyrated about a circle of smaller diameter than the hoop, the hoop will whirl about the torso or other body portion in an orbital type movement, as is well known in this type of toy. If the rotation is in the direction of arrow 8, air will be forced through opening 6 into chamber 14 and through passage 20 to impinge on edge 30 of notch 28, and be exhausted through said notch. The cutting of the air stream by edge 30 sets up a vibration of the air column in a chamber 22, and creates a whistling note. The pitch of the note depends on the length of the air column in chamber 22, and this may be adjusted by moving plug 24 to different distances from plug 18. This may be accomplished through notch 28, after first removing the staple 26 securing plug 24. Plug 16 prevents air entering chamber 14 from being dissipated forwardly in the tube.
The disposition of inlet opening 6 and notch 28 respectively in the inner and outer peripheral walls of the tube is peculiarly important to the provision of a good whistling action in a hula hoop. In the normal usage of the hoop as previously described, the actual rotation of the hoop about its axis is quite slow, since the hoop does not normally move rotationally at its point of contact with the users body. Depending on the size of the body member as compared to the diameter of the hoop, the hoop may pass orbitally several times around the users body before it has turned about its axis one full revolution. Hence the axial rotation alone would not produce sufficient speed of inlet 6 through the air to provide an efiicient whistling action. However, due to the orbital motion of the hoop, each portion of the hoop is strongly accelerated alternately toward and away from the users body, and this produces additional speed of the inlet opening relative to the air. Thus as the portion of the hoop containing inlet opening 6 is pulled rapidly toward the users body, the combined velocity resulting from both axial rotation and movement toward the users body produces ample air velocity to operate the whistling means efliciently. This combination of velocities is possible only if the air inlet and outlet are disposed respectively at the inner and outer peripheral walls of the tube. The device has been found to be virtually inoperable with any other arrangement.
Since only one portion of the hoop at a time is being moved toward the users body, it is desirable in the interests of producing a continuous whistling action to place a plurality of the whistling means just described in regularly spaced relation about the periphery of the hoop, as indicated in FIG. 1 by the corresponding pairs of inlet openings 6 and notchings 28. While four pairs are shown, it will of course be apparent that any number desired could be used. Also, since the air velocity producing the whistling action is partially dependent on the axial rotation of the hoop, it is desirable to include a series of whistling means reversed from those described above, in order that the whistling will occur when the rotation of the hoop is in the opposite direction, or in the direction of arrow 32. The parts of the reversed whistling means are indicated by primed numeral corresponding to those indicating the whistling means first described.
While I have shown and described a specific embodiment of my invention, it will be readily apparent that many minor changes of structure and operation could be made without departing from the spirit of the invention as defined by the scope of the appended claims.
I claim:
1. In combination with a circular toy hoop operable to be placed in encircling relation about a body portion of its user and to be whirled about said body portion responsively to a gyrating motion of said body portion, an air-actuated whistling means carried by said hoop and operable to be actuated by air currents generated by said whirling motion of said hoop, comprising a hollow body member having an air inlet openings at the side thereof toward the center of said hoop and an air outlet opening at the side thereof distant from the center of said hoop, and an air restricting member fixed in said body member and operable to direct a stream of air from said inlet chamber across an edge of said body member bounding said outlet opening, whereby a whistling note is created.
2. The combination recited in claim 1 with the addition of a member carried adjustably in said body member and operable to vary the length of the portion of said body member interconnected with said outlet opening, whereby to vary the pitch of said whistling note.
3. The combination as recited in claim 1 wherein said hoop is formed of tubular material, and wherein said body member constitutes a length of said tube, said inlet and outlet openings constituting openings formed respectively in the inner and outer peripheral walls of said tube with said air restricting member fixed in said tube intermediate said openings, and with the addition of a pair of plugs fixed in, said tube, to seal the portion thereof containing said inlet and outlet openings.
4. The combination as recited in claim 1 wherein said hoop is formed of tubular material, and wherein said body member constitutes a length of said tube, said inlet and outlet openings constituting openings formed respectively in the inner and outer peripheral walls of said tube with said air restricting member fixed in said tube intermediate said openings, and with the addition of a pair of plugs fixed in said tube to seal the portion thereof containing said inlet and outlet openings, the plug adjacent the outlet opening being adjustably movable along said tube whereby to adjust the pitch of the whistling note produced by said whistling means.
