Definitions
- This invention relates to a flexible kitchen utensil or spatula.
- a spatula of the common form includes a flat blade, either of thin resilient material, or of heavier, non-flexible material, which can be .used as a pie or cake server, or as a pan scraper or knife. It is apparent that such a device has some. disadvantages. If thin enough to flex easily, so as to make it possible to insert the blade easily below the pie or cake even in 8. limited space, it is not sufliciently rigid to support any considerable load. On the other hand, if made with a rigid blade, the insertion thereof beneath the article of food is much more difllcult.
- spatula in which the blade will flex or bend in response to force applied to one side thereof but will strongly resist flexure in response to force applied in the opposite direction.
- the spatula is very conveniently usable alternatively as a knife, as a scraper, as a support, or a member insertible between an article to be lifted and the surface upon which the article rests.
- the invention contemplates a spatula wherein the blade of thin resilient material is stiff and resistant to bending in one direction, whereby it is adapted for cutting or scraping, and is resilient and may be readily flexed in the opposite direction adapting it to be inserted under an object for lifting the object.
- This discrimination of resistance to flexure is achieved by having the blade substantially arcuate or arched about its longitudinal axis for at least along a substantial portion of its length.

11 Claim.
This invention relates to a flexible kitchen utensil or spatula.
A spatula of the common form includes a flat blade, either of thin resilient material, or of heavier, non-flexible material, which can be .used as a pie or cake server, or as a pan scraper or knife. It is apparent that such a device has some. disadvantages. If thin enough to flex easily, so as to make it possible to insert the blade easily below the pie or cake even in 8. limited space, it is not sufliciently rigid to support any considerable load. On the other hand, if made with a rigid blade, the insertion thereof beneath the article of food is much more difllcult.
It is one of the objects of this invention to provide a spatula of greatly increased utility,-
whereby these disadvantages are overcome, and whereby it may serve other useful purposes.
It is another object of this invention to provide a spatula in which the blade will flex or bend in response to force applied to one side thereof but will strongly resist flexure in response to force applied in the opposite direction. In this way, the spatula is very conveniently usable alternatively as a knife, as a scraper, as a support, or a member insertible between an article to be lifted and the surface upon which the article rests.
It is a further object of this invention to provide a spatula having these advantages, and which can be manufactured at low cost.
Briefly, the invention contemplates a spatula wherein the blade of thin resilient material is stiff and resistant to bending in one direction, whereby it is adapted for cutting or scraping, and is resilient and may be readily flexed in the opposite direction adapting it to be inserted under an object for lifting the object. This discrimination of resistance to flexure is achieved by having the blade substantially arcuate or arched about its longitudinal axis for at least along a substantial portion of its length.
This invention possesses many other advantages, and has other objects which may be made more easily apparent from a consideration of several embodiments of the invention. For this purpose there are shown a few forms in the drawing accompanying and forming part of the present specification. These forms shall now be described in detail, illustrating the general principles of the invention; but it is to be understood that this detailed description is not to be taken in a limiting sense, since the scope of the invention is best defined by the appended claims.
Referring to the drawing:
Figure 1 is atop plan view of a kitchen utensil or spatula, incorporating the invention;
Fig. 2 is a side elevation of a spatula of Fig. 1; Figs. 3 and 4 are sections on an enlarged scale as seen on correspondingly numbered planes of 5 Figs. 5 and 6 are diagrammatic elevations showing possible uses of the spatula;
Fig. 7 is a plan view of a modified form of kitchen utensil made in accordance with the invention; and
Fig. 8 is a detail section on an enlarged scale as seen on plane 8-8 of Fig. 7.
Referring to the drawing (Figs. 1 to 6 inclusive) the blade of the spatula is indicated by ID and is formed of thin resilient material, such as spring steel or its equivalent, of a'. thickness of the order of .010", although other metals or nonmetals may be used. The forward or advancing edge H of the blade is cut at a small deviation from a right angle with the sides and the corners are rounded in accordance with common practice. This end ll of the blade can be used as a scraper or knife. The rear of the blade l0 may be secured in an offset metal step piece I! by rivets IS. The step piece l2 in turn may be held in a kerf i4 formed in handle If, as by screws or rivets l6.
Blade I0 is substantially flat adjacent its outer end H (see Fig. 4), but is arched towards its rear end as indicated in Fig. 3. The depth of the arch obviously decreases as the edge of the blade is approached, being practically nil at the edge. The blade I0 is formed or set initially with this arch, or arcuate portion in any preferred manner. By referring to Fig. 3 it will be noted'that step piece l2 has a similar configuration, the'result of this being to hold the blade closely to its original curve when assembled and riveted inplace.
' If pressure is applied to the bottom of blade i0 near its outer edge as indicated by the arrow marked A" in Fig. 2, the blade will be substantially flattened for some distance back from the edge. Being resilient, it may be readily bent as indicated in Fig. 5, by urging .the convex side against a solid surface, such as a pie plate or cake plate i1, or any other supporting surface. That part of the blade ill in contact with the surface will be substantially flat, while near the 50 point where it diverges from the surface it will begin to assume its original arched cross-section. The flattened part is urged to the flat position by the stresses obtained in the blade l0 at the area of the transverse bend. The amount of ilat- 55 tening and flexing will obviously depend upon the amount of pressure applied, but in any event a portion of the blade will be maintained in its original arch by the step piece l2, and this ensures the return of the blade to its initial form upon the removal of the pressure.
If the pressure is applied as indicated by arrow B (Fig. 2), the pressure will tend to increase the extent and depth of the arched portion of the blade which will prevent the blade flexing and cause it to remain as shown in Fig.6. It is of course possible to apply suflicient pressure to flex the blade in .this direction too, but the pressure applied in the direction of B would always have to be very much greater than that applied in the direction of A to cause flexing. The relative amounts will depend on the material and design of the blade. This may be briefly summarized as the blade being so formed as to have discrimination with respect to the resistance to the direction of the flexing force. Accordingly, blade l0 can support an article, such as a food article, on its uppenconcave surface without any flexure; and yet it may be easily inserted under such an article by urging its convex side firmly downwardly and between the article and its support.
To use the blade "l as a scraper or cleaner, the edge llcan be placed in the position of Fig. 6, the bending force being in such direction as to encounter great resistance.
The step piece l2 may be omitted and the blade fastened directly in the kerf formed in the handle-as in the form shown in Figs. 7 and 8. It may be desirable to form the blade ill in many other configurations than that shown in Fig. 1, the better to adapt it to a wide range of uses, and this may be readily done while yet maintaining the arched cross section together with the resultant discrimination of the resistance to flexure. For example, in Fig. '7 is shown a wedge shaped blade having a sharpened edge 2|. This has utility in serving pie or cake or other similar articles of food, as the article can first be cut using the spatula as a knife; it can then be flexed as shown in Fig. 5 and forced under the severed piece, the
stiffness of the blade then coming into play to lift the piece onto the blade for removal. The handle l5 may be the same as in the first form, such as wood, or phenolic condensation product,- or any other preferred material, having an arcuate kerf I l. The blade 20 has a portion of reduced width which is inserted directly in the kerf, rivets i6 serving to retain it there.
As an indication of a convenient size for making the spatula, the overall length of the blade as shown in Figs. 1 and 2 may be made about six inches, and the other dimensions in the propertions indicated. The arched section at the back of the blade may be of the proportions shown in Fig. 3.
