United States Patent 01 hce ROLLING PIN Robert F. Petix, 1449 SE. Birch, Beaverton, Oreg. 97005; Joseph A. Aquino, 10856 Wolcott Place, Mission Hills, Calif. 94901; and Frank .I. Aquino, 6078 Dovetail Drive, Agoura, Calif. 91301 Filed Mar. 6, 1969, Ser. No. 804,824 Int. Cl. A47j 43/00 U.S. Cl. 107-50 1 Claim ABSTRACT OF THE DISCLOSURE A rolling pin has a body portion of tubuar construction forming a compartment therein. The rolling pin includes end handle members each having a disc-like base portion and a projecting gripping portion. The base portion of the handle members has exterior screw threads engageable with interior screws threads at the ends of the tubular body portion for removably attaching said handle members to the body portion. By means of such threaded engagement, one or both of such handles may be temporarily removed for the purpose of placing ice cubes or water in the body portion of the rolling pin. The handle members are adapted to be inverted so that the gripping portions thereof can be turned inwardly to project into the body portion of the rolling pin for compactness in storage.
This invention relates to new and useful improvements in rolling pins.
A primary objective of the present invention is to provide a rolling pin having a hollow interior adapted to receive ice cubes, water, or other contents for varying the temperature of the rolling surface of the rolling pin.
Another object is to provide a hollow rolling pin having a detachable handle member and having means to support a gripping portion of the handle member in either an outward projecting position for use of the rolling pin or an inward projecting position disposed interiorly of the rolling pin for storage, and more particularly to provide a hollow rolling pin having interior threads adjacent at least one end for accomplishing the detachment and selected positioning of said handle members.
Another object is to provide a rolling pin which is simplified in construction and economical to manufacture.
The invention will be better understood and additional objects and advantages will become apparent from the following description which illustrates a preferred form of the device.
In the drawings:
FIG. 1 is an elevational view of a rolling pin embodying features of the present invention, this view having portions thereof being broken away to show internal construction;
FIG. 2 is a sectional view through the rolling pin and showing gripping portions of the handles turned inwardly for storage; and
FIG. 3 is an end elevational view taken on the line 33 of FIG. 2.
Referring now in particular to the drawings, the rolling pin of the invention includes a body portion which is tubular in construction to form an inner compartment 12. Body portion 10 preferably comprises a seamless structure, and for this purpose may comprise a molded plastic prod- 3,605,648 Patented Sept. 20, 1971 net. If molded of plastic, it is preferred that it be made of substantially rigid but not brittle plastic, an example comprising a molding plastic such as a medium impact polystyrene.
The rolling pin has end handle members designated generally by the reference numeral 14. Each of these handle members has a base portion 16 and an elongated round gripping portion 18 extending perpendicularly to the base portion 16. The handle members 14 are detachably connected to the body portion 10, and for this purpose the body portion has internal threads 17 adjacent each end and the base portions 16 of the handle members have external threads 20. Handles 14 may, similar to the body portion 10, be constructed of plastic to provide a minimum in the cost of manufacture.
As best seen in FIG. 2, the base portions 16 of the handles are cup-shaped, having an annular defining wall 22 on which the threads 20 are provided. The cup-shaped base portions 16 are integral with the gripping portions 18, with the latter having projecting ends 24 which extend to the outer end edges of the cup-shaped base portions for increasing the rigidity of the structure. Gripping portions 18 of the handle members may be hollow for reducing the cost of manufacture.
As seen in FIG. 3, the base portions 16 of the handle members have a pair of diametrically extending webs 26, such webs extending between the outer wall 22 and the projecting end 24 of the gripping portions 18. The purpose of the webs 26 is to provide gripping areas at the base end of the handle members for the purpose of rotatably inserting said handle members in the body-member or for removing them.
In the normal use of the rolling pin, the handle members 14 are threadedly attached to the threaded portions 17 of the body portion 10 with the gripping portions 18 projecting outwardly as shown in FIG. 1, whereby the handles can be grasped for manipulating the rolling pin. Since the body portion 10 is hollow, one of the handle members 14 may be removed temporarily for inserting ice, cold water, or other contents in the compartment 12 to chill the rolling surface of the rolling pin since chilling of the roller surface may in some instances add to the efficient usage thereof. Likewise, heated contents may be inserted if it is desired that the rolling surface be heated.
For the purpose of shipping or storing the rolling pin, the handle members are inverted so that the gripping portions project inwardly into the compartment 12 as shown in FIG. 2. In this position, the base portions 16 of the handle members are likewise threadedly engaged with the end threaded portions 17 of the body portion 10.
It is to be understood that the form of our invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to Without departing from the spirit of our invention.
Having thus described our invention, we claim:
1. A rolling pin comprising (a) a body portion,
(b) said body portion having a cylindrical tubular construction forming a hollow interior and also having open ends,
(c) a pair of handles having inner and outer ends,
(d) each of said handles having a radially disposed a 3 4 flange secured thereto adjacent to its inner end but (h) and a web member extending diametrically across spaced toward the outer end with relation to said insaid base portions between said flange and the hanner end, dles to reinforce said handles and to provide a grip- (e) said flange having anannular defining wall directed for rotating the handles into and out of threaded toward said inner end and terminating substantially 5 engagement with said body portion when said handles flush with said inner end, project inwardly of said body portion. (f) said annular defining wall having exterior screw th d References Cited (g) interior screw threads on said body portion ad- UNITED STATES PATENTS jacent to the ends thereof for threadedly receiving 10 the handles in two positions one with the handles. projecting outwardly in a use condition for operating the rolling pin and the other with the handles extending inwardly into said body portion for compacting the size of the rolling pin for storage,
