The present invention relates to a foldable utensil for mounting on a container and being stored therewith for minimizing storage space of the container and the utensil combination.
Foldable eating utensils have long existed for camping and the like. A utensil has even existed having means for mounting the utensil on the rim of a food container. However, a mountable utensil having structures to allow easy reconfiguration between use and storage, all in a simple yet robust product that is reasonably priced, has escaped recognition and solution.
Briefly summarized, the present invention relates to a three component utensil including a first component for handling the utensil, the first component having a longitudinal axis, a second component connected to the first component, the second component having a utility portion, an inverted U-shaped mounting portion and a tab portion, the U-shaped mounting portion for mounting the utensil on a rim of a container wherein the container includes sidewalls, the second component having a longitudinal axis and being movable between a first position during use where the longitudinal axes of the first component and of the second component are generally parallel to each other and a second position during storage where the longitudinal axes of the first component and of the second component are generally perpendicular to each other when the utensil is mounted to the container rim and the utility portion extends over contents in the container and the first component extends along one of the sidewalls of the container, and a third component mounted to the first component for rotation about a horizontal axis, wherein the tab portion of the second component is mounted to the third component and rotates therewith for minimizing the space of the utensil and the container when the utensil and container are stored.
The present invention also includes a method for assembling a foldable utensil including the steps of providing a handle, providing a spreader blade having an inverted U shaped mounting portion for mounting the utensil on a rim of a container for storage of the utensil and the container, providing a pivot block, forming a first structure on the handle and a second structure on the pivot block to maintain relative movement between the spreader blade and the handle when the spreader blade is extended for use, securing the spreader blade to the pivot block, and rotatably connecting the pivot block to the handle for storing the utensil in a folded position on the container.
For the purpose of facilitating an understanding of the invention, the accompanying drawings and detailed description illustrate preferred embodiments thereof, from which the invention, its structures, its construction and operation, its processes, and many related advantages may be readily understood and appreciated.
The following description is provided to enable those skilled in the art to make and use the described embodiments set forth in the best mode contemplated for carrying out the invention. Various modifications, equivalents, variations, and alternatives, however, will become readily apparent to those skilled in the art. Any and all such modifications, variations, equivalents, and alternatives are intended to fall within the spirit and scope of the present invention.
An embodiment of the foldable utensil 10 is illustrated in
It is noted that the spreader utensil may have other uses, such as applying spackling paste to a wall or grout to tile, for example, and may have other instruments instead of the spreader blade for allowing other activities, such as those disclosed herein below.
The blade 12 of the spreader utensil 10 may have a forward spreader portion 30,
In the alternative, the looped portion 40 of the spreader may be scaled up or down so as to be mountable on containers of different sizes and shapes.
The handle 14 may have a convenient shape with a grip portion 50,
The term ‘detent’ used here means a mechanism or device that temporarily keeps one component or part in a certain relative position to that of another, and can be released by applying force to one of the components or parts. Here, the two components are the pivot block 16 (to which the blade 12 is attached such that the blade and pivot block move together) and the handle 14. The mechanism or device may consist two elements, a protrusion and a mating recess or groove. Also here, the two detent elements, each a protrusion and a mating groove/recess, cooperate to maintain the blade 12 and the handle 14 in one of two positions chosen by a user. For example, the foldable utensil here is designed to have three sets of detents for the pivot block and the handle: two sets to maintain the blade and the handle in an extended configuration where their longitudinal axes 42, 60 are generally parallel to one another as shown in
The phrase ‘movement limiting structures’ used here refers to structures that abut one another to limit or block movement.
The arms 64, 66,
The pivot block 16,
The rounded shafts 92, 94 are intended to be received by the openings 76, 78 in handle arms 62, 64, respectively, so that the pivot block 16 is enabled to rotated roughly 90°, between the extended configuration illustrated in
The front wall 88 of the pivot block 16 includes the slit opening 110 for receiving the tab portion 36 of the blade 12, and enables the blade to be secured to the pivot block so as to rotate with the pivot block as one assembly. The rear wall 90 of the pivot block and the front wall 62 of the handle may include a third movement hindering structures where a third detent may consist of a first detent element, the protrusion 112,
The curved lower portion 114 of the pivot block rear wall 90 is designed to enable the pivot block 16 to rotate easily relative to the handle 14 when the blade 12 moves relative to the handle 14 between the extended and folded configurations. First movement limiting structures of the utensil 10 consists of an upper portion abutment surface 116 on the pivot block rear wall 90, which is positioned to engage the abutment surface 70 of the handle 14 when the utensil is extended for use. The first movement limiting structures, the abutment surface 116 and the abutment surface 70, prevent or block the blade 12 from moving upward (or rotating clockwise when viewed in
The term ‘abutment’ here refers to the part of a structure that directly receives thrust or pressure. For example, should a user attempt to bend or rotate the blade 12 upward from the configuration shown in
Referring again to
In the alternative, the protrusions and mating grooves may be reversed in some cases, for example, on the front wall 62 of the handle 14, the groove 68 may instead be a protrusion, and on the pivot block 16, the mating protrusion 112 may instead be a groove. Also in the alternative, the detent elements may be mating small mounds and holes or other suitable configurations. In another alternative, other devices, such as pins and holes may be used, if desired.
The blade may be formed of any suitable material, such as stainless steel, plastic, ceramic, silicone or stainless steel with a ceramic coating. For example, 304 grade stainless steel, 18/8 or 18/10 (percent of chromium and nickel) may be used. The handle may also be made of any suitable material, such as a polypropylene or polystyrene or a suitable composite. The blade may have a length of about 65 mm and be about 1 mm thick (between the surfaces 32 and 34,
The pivot block may be about 15.5 mm between the front wall 88 and the extent of the protrusion 112 on the rear wall 90, about 18 mm between the sidewall 80 and the sidewall 82, and about 12 mm between the top wall 84 and the bottom wall 86.
Other embodiments of the foldable utensil may now be considered. For example, the instrument of a mountable and foldable utensil 120,
In operation, the foldable utensil with detents operates in one of two positions or configurations. When in use as a spreader, the blade 12 is extended relative to the handle 14 such that the longitudinal axis 42 of the spreader blade is generally parallel to the longitudinal axis 60 of the handle. A first set of detent elements maintains the utensil in its extended configuration (and the engagement of abutment surfaces prevents the spreader from folding upward). In use, the spreader is handled such that any pressure, such as when the user is scooping butter from a tub, is applied to the bottom surface 34 of the spreader portion 30 of the blade 12. In this fashion, the blade will not fold because the abutment surface 116 will bear against the abutment surface 70. After use, the user may mount the spreader 10 to the rim 20 of the tub 18 and easily fold the handle downward for convenient storage. When folded, the longitudinal axis 60 of the handle 14 is approximately or roughly perpendicular to the longitudinal axis 42 of the spreader blade 12. A second set of detent elements maintains the spreader 10 in its folded configuration. In both the extended and the folded positions, the detents are positioned on the handle 14 and on the pivot block 16 to resist movement away from the position selected by the user, namely, the extended or the folded position; however, with a slight force provided by the user, the foldable utensil may easily be moved from one position to the other position. When the user desires to again use the spreader, the lid 22 of the tub 18 is removed and the spreader may be extended and dismounted from the tub (or the spreader may be dismounted and then extended).
It is noted that throughout this detailed description, words such as “front” and “rear,” “forward” and “rearward,” and “up” and “down,” as well as similar positional or locational terms, refer to portions or elements of the utensil apparatus as they are viewed in the drawings relative to other portions, or in relationship to the positions of the apparatus as it will typically be held and moved by a user, or to movements of elements based on the configurations illustrated. Terms such as “generally” means “about” or “approximately.”
The present invention also includes a method 150,
The mountable foldable utensil with detents disclosed in detail above is easy to use, is simple in structure and yet is robust, and may be produced at a reasonable cost. The mountable foldable utensil saves time in handling the apparatus and may be efficiently stored.
From the foregoing, it can be seen that there has been provided features and advantages for an improved mountable and foldable utensil and a disclosure of a method for assembling the mountable and foldable utensil. While particular embodiments and variations of the present invention have been shown and/or described in great detail, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects. Therefore, the aim is to cover all such changes and modifications as fall within the true spirit and scope of the invention as defined in corresponding allowable claims. The matters set forth in the foregoing description and accompanying drawings are offered by way of illustrations only and not as limitations. Again, the actual scope of the invention is to be defined by corresponding allowable claims.
This application is a continuation and claims priority pursuant to 35 U.S.C. 120 from U.S. patent application Ser. No. 16/901,928, entitled MOUNTABLE AND FOLDABLE UTENSIL WITH STRUCTURE FOR HINDERING AND LIMITING MOVEMENT OF UTENSIL COMPONENTS filed on Jun. 15, 2020, which Application is expressly incorporated herein by reference.
