material : the hook is a die cut shape stamped out of a single material , which is monolithic in nature . ( i . e . composed of a single material that is homogeneous throughout the material itself ). this material may be any rigid homogeneous material which may be die cut the by conventional steel rule die cut methods . materials may include : expanded p . v . c . foam , pressed fiber board , aluminum , brass , styrene plastic , or their equivalents . material thickness may range from { fraction ( 1 / 16 )} th of an inch to ⅛ th of an inch . the preferred embodiment is composed of a 3 - mm ( 0 . 118 inches ) nominal ⅛ th inch thick , expanded pvc foam which is manufactured in sheets of approximately 48 ″ by 96 ″. ( thickness is described in the attached drawings fig2 page 1 of 1 front elevation ) a . may be trimmed with simple hand held cutting tools ( such as scissors ) c . is available in a variety of colors that are integral to the material ( i . e . part of the materials composition and not applied to the surface ). f . has an impact resistance of 5 inch pounds at 70 degrees f . features of the hooks portion &# 39 ; s note : this section is for the purpose of defining the hooks functional features . description of the “ hook portions ” should not construe separate physical parts of the hook . the material of the hook is monolithic and homogeneous throughout and comprises all three portions of the hook ( see figure ) without any mechanical , bonded or geometric connections to join them . the slotted standard interface : fig4 ( a ): the “ slotted standard interface ” portion of the hook is configured so as to provide a positive engagement of the two interface segments in the preferred embodiment . ( other embodiments may be comprised of more or less than two interface segments ). positive engagement is achieved when the surface “ h 1 ” ( see fig3 ) passes into and through a slot in the slotted standard and is moved downward over distance “ h 2 ” ( see fig3 ). gravity causes the hook to remain in this position creating resistance to any horizontal or downward vertical movement of the hook providing a positive engagement and capability for supporting objects by hanging . angle “ x ” ( see fig3 ) allows the hook to fit slotted standards of varying material thickness &# 39 ; note : where embodiments are composed of two or more interface segments ( see fig4 ( a )) the segments must be equally spaced apart from each other so that are in line with the slots of the slotted standard . the body : fig4 ( b ): the “ body ” portion is configured so as to connect the “ slotted standard interface ” portion and the “ hanger ” portion of the hook . the width ( w ) may vary based on the depth required to allow the “ hanger ” portion of the hook to protrude outward far enough to be accessible where the slotted standard contains any recess from the outer surface of the standard itself to the outer surface of the slot or where the slotted standard is recessed into another surface material . the hanger : fig4 ( c ): the “ hanger ” portion of the hook is comprised of single or multiple “ peninsula ” like protrusions of sufficient length to allow for an object to be laid over them and be supported without slipping off . in its preferred embodiment there are two protrusions . the upper protrusion being longer than the lower protrusion . the “ hanger ” is proportioned over its length ( l ) and depth ( d ) such that it has a structural capability sufficient to support items of up to 25 pounds . the upper edge of each “ hanger ” has a downward slope in the direction of the slotted standard to limit objects from slipping off of the “ hanger ” by utilizing gravity to force objects to be captured against the slotted standard . in its preferred embodiment the upper edges are a continuous smooth surface with no specific details . ( see fig4 ( s )). however in alternate embodiments the upper end may be shaped in such a way as to allow specific shapes such as the diameter of a wire clothes hanger to nest in the shape . ( see fig5 ( s 2 )) manufacture : the hook is manufactured using conventional steel rule die cut methods . ( this method could be described as “ cookie cutter ” since it is very similar to the process used in making cookies of different shapes with what is known as a cookie cutter .) this method incorporates the use of a die form in the shape of the hook . ( the shape is described in the attached drawings fig1 - 6 ) this die form is used in a die press with a flat bed where the object material ( p . v . c . foam ) is placed . the press is then lowered with the die form so that it stamps ( cuts ) through an un - cut portion of p . v . c . foam material on the flatbed of the die cut press . the material is then fed through the machine so that a new area of un - cut material is placed below the die for each successive stamping . this process is repeated to create multiple hooks . due to the “ softness ’ of the material no additional processing such as polishing , sanding filing , or buffing is required after cutting either on its side surfaces or on its edges . this feature substantially decreases manufacturing costs . use : the hook is used by individuals either in office or residential setting to provide hanging capability for personal items , which may include but are not limited to such items as , hats , coats , jackets , purses , bags with shoulder straps , umbrellas and small household utensils tools and pictures . the hook is placed into position by hand without the use of tools or other ancillary devices . it fits into any two contiguous slots in a wall standard so that the “ slots interface portion ” of the hook ( described in the attached drawings fig4 ( a )) passes into the slots . it is then slid downward the until the “ slots interface ” is positively engaged with the wall standard so that it cannot be dislodged when a downward vertical force ( shear ) or any horizontal force perpendicular to the wall standard ( pull ) is exerted upon it . once it is positively engaged in this manner , items may be hung upon it . similarly it is removable by hand without the use of tools or other devices when an upward force is applied until the interface portion of the hook aligns with the slot openings so that it may be pulled out horizontally . the hook is reusable ( unless it has been damaged ) and may be placed in any other two contiguous slots along the wall standard by repeating the engagement steps .
the purpose of this product heretofore known as the hook is to provide the ability to hang personal items on slotted tracks of office systems furniture and residential wall tracks . it is unique in that there is currently no provision for a small , light , inexpensive hanging device available in a choice of so many colors which serves this purpose .
