Abstract
A device, system, and method for holding one or more structural long objects includes a plurality of adjacent flat membranes that are in direct contact with each other. The membranes have been slit to produce tabs that meet near a center of the membranes to hold the structural long object(s) more effectively than could be accomplished with a single flat membrane with tabs. The membranes are held in the body of the device or system by a retaining device located on one side of the membranes and a retaining feature of the body on the other side of the membranes.

Rather, the ensuing description of embodiment(s) will provide those skilled in the art with an enabling description for implementing a preferred exemplary embodiment. Consequently, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the presented inventions. The embodiments described herein are further intended to explain the best modes known of practicing the inventions and to enable others skilled in the art to utilize the inventions in such, or other embodiments and with various modifications and combinations of features and elements required by the particular application(s) or use(s) of the presented inventions.
(41) It should be understood that various changes could be made in the function and arrangement of elements without departing from the spirit and scope as set forth in the appended claims. Preferred embodiments of the present invention are illustrated in the Figures, like numerals being used to refer to like and corresponding parts of the various drawings. Specific details are given in the following description to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details.
(42) In a preferred embodiment, the holder for structural long objects incorporates multiple adjacent slotted diaphragms designed to hold one or more structural long objects. As used herein the term structural long objects has specific meaning, in which: structural refers to objects that maintain their intended manufactured form when fully supported with no external strain-inducing load (i.e. the objects are sufficiently rigid to support themselves when the longest dimension is oriented vertically); and long objects means objects that have a significantly greater length (longest dimension) than those dimensions that are perpendicular to this length (width and thickness). For purposes of this invention description and the appended claims a long object is one having a length at least four times greater than its width (where width is defined as a dimension perpendicular to the length throughout a majority of the length of the object) and at least four times greater than its thickness (where thickness is defined as a dimension orthogonal to the length and the width throughout at least a majority of the length).
(43) Examples of objects that are structural long objects include, but are not limited to the following: (a) Office items such as writing implements, scissors, and small tools, (b) Sports items such as skis, golf tees, and fishing poles; (c) Tools such as paint brushes, screwdrivers, hammers, metal files, garden rakes, and brooms; and (d) Household items such as tooth brushes, dental flossers, cosmetic brushes, and kitchen utensils.
(44) Reference will now be made to the accompanying drawings, which can assist in illustrating various pertinent features of the presented embodiments.
(45)
(46) Examples of materials and configurations that can be used for diaphragms (also called membranes) in embodiments of the present invention can include, but are not limited to elastomers (viscoelastic materials) such as: (a) Synthetic polymers; (b) Natural polymers such as natural polyisoprene (natural rubber); (c) Synthetic polyisoprene; (d) Polybutadiene (butadiene rubber); (e) Butyl rubber (copolymer of isobutylene and isoprene); (f) Styrene-butadiene copolymers; (g) Nitrile rubber (copolymer of butadiene and acrylonitrile); (h) EPDM (ethylene propylene diene rubber); (i) Epichlorohydrin rubber (ECO); (j) Polyacrylic rubber; (k) Silicone rubber; (l) Fluorosilicone rubber; (m) Fluoroelastomers; (n) Polyether block amides; (o) Polyethylene based elastomers; (p) Polypropylene based elastomers; (q) Vinyl-based elastomers; (r) Thermoplastic elastomers; (s) Polytetrafluorethylene (Teflon) based elastomers; (t) Polysulfide-based elastomers; and (u) Chloroprene based elastomers, such as neoprene.
(47) In one embodiment, the second diaphragm 151 comprises a 1/16-inch-thick layer of rubber and the first diaphragm 152 comprises a 1/16-inch-thick layer of neoprene. The rubber diaphragm 151 in this embodiment has a Shore A Durometer Hardness of between 40 and 50. The neoprene diaphragm 152 in this embodiment has a Shore A Durometer Hardness of between 40 and 50.
(48) It should be noted that embodiments of the present invention can be made with any plurality of diaphragms. Although the figures show only two diaphragms in each stack, a diaphragm stack could also comprise three diaphragms, four diaphragms, five diaphragms, etc. There can be one diaphragm stack in an object holder, two diaphragm stacks, three diaphragm stacks, four diaphragm stacks, etc. The diaphragms can be thin. The diaphragms can be planar when in their rest states. The diaphragms can have a constant thickness in all regions except those that have been completely removed. Diaphragms in a stack can be parallel to each other. Diaphragm stacks can be parallel to each other. The diaphragms shown in

(52)
(53) Diaphragms 150A and 150B in
(54) As a structural long object 330 passes through the diaphragm 150A, the tabs flex such that they are pushed inward into the recessed surface of the cylindrical housing of the circular holding device 120. Distal portions of at least a portion of the tabs engage the structural long object and work to maintain the object within the device. That is, the resiliency of the tabs provides a retaining force that securely holds the structural long object 330 within the holding device 120. However, by applying a sufficient pulling force, the tabs will release the object 330, in this example a screwdriver. Note that when the tabs deflect toward each other, the deflectable distal ends of the tabs in one diaphragm move in response to the movement of the deflectable distal ends of the other diaphragm when the tabs in the one diaphragm move in the direction of the other diaphragm.
(55) Further referring to
(56) Referring to
(57) It can be appreciated that the diaphragms or membranes can have tabs shaped in any configuration capable of being created by anyone skilled in the art. Referring to
The diaphragms shown in
The individual diaphragms as presented may embody a contiguous membrane or a plurality of individual geometrically shaped tabs to comprise a full diaphragm. Note that at least some of the slits shown have at least one end that extends outward toward the periphery of the diaphragm.
(58) Referring to the exploded view of a cylindrical closed bottom holding device 160 shown in
(59) In the embodiment shown in
(60) As shown in the embodiment of
(61) It has been recognized that utilization of multiple diaphragms allows for providing adequate retention force for maintaining an object within the holding device while allowing the use of softer materials to form the diaphragms. In this regard, softer diaphragms allow the device to hold objects with very small effective diameters as well as objects exhibiting larger effective diameters. The present inventor has discovered that devices known in the prior art are limited with regard to the size and thickness of objects that such devices can retain. These limitations occur at least partially due to properties associated with materials utilized in the construction of the diaphragm. Examples of limitations associated with prior art devices include the following. To hold objects with small effective diameter, the tabs 156A and 156B in
(62) Embodiments of the invention can address problems associated with size and thickness constraints associated with prior art devices. That is, rather than utilizing a stiffer plastic diaphragm, the diaphragms in a device incorporating embodiments of the invention are typically comprised of an elastomeric material that is considerably more pliable than most plastics. In this regard, it has been found by the inventor that materials having a Shore A Durometer hardness of less than 90 provide a suitable diaphragm for the holding device. Accordingly, use of lower Durometer materials, such as Shore A Durometer 90 and lower in a single diaphragm configuration can result in failure to retain structural long objects within the holding device. Therefore, to hold thicker structural long objects, prior art single adjacent diaphragm holding devices typically utilize tabs that have a gap between the tips of the tabs. As will be appreciated, if an object holder incorporates a gap between opposing tabs, it cannot hold structural long objects exhibiting a smaller effective diameter without design changes.
(63) More specifically, materials having a Shore A durometer hardness of less than 90, more preferably less than 80 and yet more preferably less than about 70 provide diaphragms that allow deflection that is adequate to permit insertion of large effective diameter structural long objects while also permitting the engagement of small effective diameter structural long objects. In one particular embodiment, the device utilizes neoprene rubber diaphragms having a thickness of approximately 1/16 of an inch. In contrast, most plastics (e.g., polyethylene, polypropylene etc.) have a Durometer hardness considerably in excess of the claimed range. That is, many plastics are too hard to be measured utilizing the Shore A Durometer scale. For instance, most plastics have a minimum Shore D Durometer hardness of 55, which equates to a hardness that is greater than the maximum measure of Shore A Durometer hardness.
(64) The use of the multiple diaphragms allows for providing sufficient retention force to maintain a thicker and/or heavier structural long object or objects object within the holding device. That is, even though each tab of the softer diaphragm material has a reduced resiliency, the increased number of tabs provided by the multiple diaphragms results in a holding device having sufficient retention force for as broad of a range of object shapes and sizes as possible. Further, the use of a softer diaphragm material reduces the potential of painful or injurious results to a user's finger that is inserted into the device. That is, prior art devices having hard plastic tabs can result in a situation where a user pushes their finger through the stiffer tabs, which pinch the finger upon removal. Utilization of the more easily deflectable tabs prevents such inconvenience for the user. That is, the pliability of the tab material permits removal of a user's finger without risk of injurious or painful use.
