F. R. BARBEE ARTICLE HOLDER Filed Jan. 15
Feb. 21, 1967 DIAGONAL RIB INVENTOR. FLOYD R. BARBEE AGENT United States Patent 3,305,100 ARTICLE HOLDER Floyd R. Barbee, 5716 /2 N. Charlotte, San Gabriel, Calif. 91775 Filed Jan. 15, 1965, Ser. No. 425,826 8 Claims. (Cl. 211-60) This invention relates to tool hanger devices and more particularly to means which may be assembled together to produce tool hanger strip assemblies of improving holding power and other qualities.
Any number of wall attachment means are provided in the prior art by which one may clamp-in the handles of tools, brooms and other household articles. Usually these articles are formed of a unitary element which is normally of a resilient material and the forming brings forward from the unitary element a pair of shaped resilient tynes which tend to spring together so that an article placed between the tynes is held in place under the resilient urge of the tynes. Such prior devices are frequently readily fatigued because the strains, placed on them in the insertion and removal of the articles to be held therein, tend to lessen their clamping strength and ultimately they fracture. Additionally, the prior art devices generally press upon the articles in their grasp at'two points unless formed into complex tyne configurations for which fabrication of tools is both costly and difiicult. Such tyne configurations tend to surround the article in a manner making it difiicult to remove the article from their grip.
This invention contemplates a novel resilient tension clip means involving an end part and central parts with which strips of tool hangers may be made up to accomrnodate a great many tools. The end part is essentially half of a central part and no more material is required for thick handled articles than for thinner articles, the spacing of the juxtapositioned end and central parts on the assembly strip or bar being varied for the various thickness of article handles beyond certain limits which are imposed when individual end and central parts are placed contiguously on the assembly strip.
According to the invention an end unit consists of a generally L shaped element, the vertical arm of which has the general form of a thin Gothic cathedral arch and the fiat portion is a continuation of, and normal to, one pier of the arch, the remaining pier of the arch being free. A central unit has a pier of end units in mirror image either end in the form of two such Gothic arch structures on opposite ends of a fiat central portion. The pier of the Gothic arch not continuous with the flat portion is free to be compressed toward'its pier mate. The action of pressing against the free pier, due to the diagonal vaulting rib portions of the arch causes the arch to move as a whole so that when a pair of free end piers are in contact with one another, and an article such as a tool handle is pressed between them, and moved from the boss of the arch to the base of the tool holder assembly bar on which they are mounted, the free pier ends execute a rocking motion, ending up by the free ends clamping the tool handie against the mounting bar. T he points of the two arches, where each tree pier end and its continuing diagonal join, are in contact to securely hold the tool handle in place.
Accordingly, it is an object of this invention to provide tool hanger clamping elements incorporating a central portion and an end portion which may be assembled in a plurality of such elements on a mounting bar.
It is a further object of this invention to provide tool hanger elements wherein one part includes a pair of such elements on a common base in mirror image relation and the other part is a single element ofthe mirror image pair.
3,3fi-5Jfi Patented Feb. 21, 1967 It is another object of this invention to provide tool hanger clamping elements having a Gothic cathedral arch configuration wherein one half of the clamping element is a free pier of such an arch configured to apply a resilient urge against a juxtaposed mating free pier of a contiguous element.
It is a still further object of this invention to provide tool hanger clamping means the parts of which are arranged to have a novel resilient rocking action against one another whereby when a tool handle is inserted therein the free rocking ends form generally triangular resilient clamping mechanism with the mounting base upon which the means is assembled.
It is still another object of this invention to provide tool hanger strip assemblies comprising an array of dual Gothic arch-shaped resilient clamping elements mounted end to end, their resilient urges against one another pro viding secure and tight holding means for tools inserted therebetween.
These and other objects of the invention will become more clear from the specification thereof which follows wherein a representative group of embodiments thereof are shown in the figures and described. It is to be fully understood that the embodiments shown and described are not intended, or to be construed, as limiting the invention thereto, since those skilled in the arts appertaining thereto will be able to devise other embodiments, in the light of the teachings herein, within the ambit of the appended claims.
In the drawings:
FIGURE 1 is a partially broken perspective view of a representative assembly of tool clamping elements as made and used according to this invention assembled to a mounting bar;
FIGURE 2 is a cross sectional view through 22 of FIGURE 1 showing the assembly of elements thereof by spot welding a form of assembly thereof;
FIGURE 3 is a view similar to that of FIGURE 2 showing the assembly of articles of the invention to a wooden surface;
FIGURE 4 is a top plan view of the elements of the inventive assembly riveted to a mounting bar and showing in cross section the steps of insertion of a tool handle and the articulation of the elements of the invention in clamping of such handles;
FIGURE 5 is a detail of another configuration of the clamping portions of an assembly of the invention to show how various frictional surfaces may be supplied therein; and
FIGURE 6 is an explanatory illustration detailing the configuration elements of a Gothic arch as applied to the invention.
Referring now to FIGURE 1 wherein a mounting bar 10 is shown, the clamping elements of this invention attached to bar iii may be seen to include end pieces such as 1113, 1i'-13 and central pieces such as 12-14-15.
Wherever this description end elements such 13-13 or central elements as 112-1445 are shown they are identified by the same reference characters or their primes such as 1113, etc.
The basic structural characteristics of the eenients of the invention are shown in FIGURE 6. The Gothic arch configuration shown therein includes what may be described as a foot member 53 from which raises a pier 51 normal to foot 53. Curving inwardiy from pier 51 and continuous therewith is a diagonal rib portion 56 terminating in a boss 55.
The pier 51 and rib 56 may be considered singleleaf flat spring anchored at 5% and having a generally parabolic curve along its length. Such a spring structure will have a strength twice as great as a fiat spring of the same dimension anchored in the same manner and a resilience three times as great as the equivalent fiat spring.
According to tables on page 454 of Marks Mechanical Engineers Handbook, fifth edition, published 1951 by McGraw-I-Iill of New York, where strength, a, of a fiat spring for a given load equals ZS 3E, the parabolic configuration of this invention yields a strength a, of 45 3E where S is the safe stress due to bending in p.s.i., and E is Young modulus of elasticity in the tensional mode for the material used. In the present invention stainless steel is used preferably but other resilient spring materials may be used. In the same tables the value for deflection or resilience U of the fiat spring is .33S 6E whereas for a parabolic spring according to this invention the deflection U is 8 6E.
From boss 55 an opposite diagonal rib 57 and a free pier 52 extend downward. In dashed line at 54 there is indicated the foot extension of pier 52 which is not present in the configuration used in this invention but would have been to complete the arch were the pier 52 and rib 57 not free. Pier 52 and rib 57 form a similar parabolic flatspring to pier 51 and rib 56, the former being anchored at boss 55. Thus it may be seen that the arch as used herein comprises a single foot member 53 supporting a pier 51 continuing through a diagonal rib 56 in a generally parabolic configuration to a boss or apex 55. There follow from boss 55 an opposite diagonal rib 57 and pier 52 in an opposite parabolic configuration. Pier 52 is free to flex about boss 55 using boss 55 as a pivot. Pier'51 is captive on foot 53 and will pivot about the junction'58 of foot 53 and pier 51. Thus any pressure applied as shown by arrow 59 against free pier 52 will both flex pier 52 on boss 55 and also apply pressure against boss 55 which will move pier 51 to hex about foot 53. When the pressure of arrow 59 is applied closer to boss 55 more force is exerted on pier 51 and diagonal rib 56. The displacement of piers 51 and 52 are indicated by the dashed line positions thereof shown at 51a, 52a.
In the assembly shown in FIGURE 1 three articles 17, 19, 21 may be seen inserted by their handles 18, 2t), 22 respectively between arch elements 13, 14; 15, 14'; and 13' respectively. In FIGURE 4 three positions of the handle are shown at 25, 26, 27. In FIGURE 4 a handle element at' 27 is shown as it is being inserted between the free piers 52, 52 of the pair of arch elements 15 and 13' causing bosses thereof 55 and 55 to separate due to the pressure close to bosses 55 and 55. At this point piers 52, 52' remain in contact. As may be seen at 26 when the handle is pressed further between arches 14-15 towards mounting base 10, free piers 52,52 are forced apart. Continuing pressure goes beyond the point of balance between the resilient urge of free piers 52, 52' against bosses 55, 55 and the pressure against less restricted piers 51, 51' so that as free piers 52, 52 separate at their free ends bosses 55, 55 come closer together. This may be seen at where the handle is now securely held in place by arch elements 13-14. The ends of piers 52, 52' and the base It) forms a tight triangular nest to hold the tool handle as shown at 25.
As has been previously pointed out there are two basic elements forming part of an assembly of tool holding brackets according to the invention. One is the end piece 11-13 exemplified by A in FIGURE 1 and the other is a central piece 12-14-15 exemplified by B in FIGURE 1. Similar central pieces are shown in part at C and D to illustrate the fact that in an array of clamps according to the invention there may be many central elements or one central element such as B, C or D but two opposite end pieces A, A must always complete an assembly. An assembly thus makes up at least a holder for two tools and consists of one element B and elements A, A.
Elements such as A, B, C, D, or A may be mounted to a wood or other wall 66 as indicated in FIGURE 3 by wood screws through perforations 61 provided for such mounting of the assembly. Arch elements A, A, B or C, D riveted to a metallic bracket such as 10 as may be seen in FIGURE 5. They may be spot Welded as indicated at 64 in FIGURES 2 and 4.
In any case wall mounted tool and other accessory clamping means according to this invention comprise an end piece and a central piece. An end piece such as A, A has a foot 53 forming a mounting for the end piece, a pier element 51 rising approximately at a right angle from foot 53 and being resiliently articulatable on the angle junction 58, a diagonal rib 56 continuing from pier 51 in a gentle arched curve to an apex or boss 55, an opposite diagonal rib 57 and free pier 52 extending from boss 55 in mirror image relation to rib 56 and pier 51. Rib 57 and pier 52 are articulatable on boss 55 in a manner similar to the action at pier-foot junction 58. The free end of pier 52 is movable by pressure thereon as indicated by arrow 59 against both its own resilient urge and that due to the junction with boss 55 through the resilient urge of pier 51. Because in normal use foot 53 is captive when the article is attached to a wall 66 or mounting bracket such as 10, pier 52 moves more freely than pier 51 when pressure is applied.
A central piece such as B, C, D consists of two end pieces such as above described having a common foot. This is clearly seen in FIGURES 1 and 2, wherein arch elements 14 and 15 can be seen to be identical but mirror image elements having a common mounting foot 12; When two end pieces 11-13 and 11'-13' and one central piece 14-12-15 are mounted to a wall 66 or other struc-' ture as shown in FIGURE 3 a minimum assembly of the elements of the invention is accomplished. While not shown specifically it is clear that a single clamp would comprise an end element A and an element A assembled in mirror image relation with free pier ends 52 being contiguous. A form of this is illustrated in FIGURE 5.
From the above discussion it should be clear that single and plural clamping assemblies may be made up from the end piece elements A, A and the central elements B, C, D attached to wall structures directly as in FIGURE 3 or to assembly bars such as 10 shown in the other figures. It should also be clear as shown in FIGURE 5 at 33 that the free pier end of the arch structure such as A or A or the other arch structures may be crimped, crenelated or corrugated, or otherwise formed with friction creating surfaces to add to the holding capacity thereof. In the latter embodiments (FIG. 5) the same configurations are possible as with the fiat surface arch shown in the other figures.
