Application ‘September 15, 1945, Serial No. 616,489 1 Claim. (01. 211-123) 2 This invention relates to lattice-like structures, such as, for examplamusic bar standards, display stands, frames and like articles of manufacture, and is concerned more particularly with an im proved method and means of joining the crossbars of the frame to their transverse supports. v A primary aim of the invention is to obtain an easily assembled yet‘ ?rm and substantially‘ rigid connection, between the several frame ele» ments whereby to build into a structure of ‘this _ character a high degree of resistance to twisting of and a minimum ‘to diagonally quantity applied of material. forces, with ‘ the preferably in two parts, each of which is pre-r formed with a series of semi-circular shaped‘re cessesspaced therealong. The recesses, in the case of a music bar stand, are uniformly spaced apart and are disposed alternately along each side of the‘standard. 'Two‘ of such preformed elements, when placed‘ in reversed position ad jacent each other, constitute 'a‘ single standard, and the alternated recesses in each being oifs'et but their-projected shapes forming cavities for re reception and support of the rods.‘ When the rods are in place, the general effect is‘ one of ‘ weaving, that is, each upright member appears as woven over and under the respective rods, with A‘furtheraim of the invention is to overcome certain inherentweaknesses and di?culties en» 15 each of the uprights oppositely woven. When ‘so related the frame elements mutually coact and countered in‘ the ‘manufacture and‘assembli‘ng of function to grip the respective rods about a sub lattice-like structures, to simplify and reduce the operations involved- in ?tting and‘ assembling the stantial portion of their perimeters. With a joint zontally disposed bars‘ (representing lines)’ are with the annexed'drawin'g. of this character, at ‘least three upright members parts, "and to render available an improved design of joint that not only is attractive from the orna 20 arerequiredjcne facing one‘way between two fac ing the opposite, but it is preferable toemploy four mental aspect ‘but which is also functionally members, two‘ at each end of the music bar or superior and more stable than is the joint obtained stand,‘ and ‘additional uprights intervening if the when ‘resort ‘is had‘ to conventional methods of expanse or area‘is‘ relatively large; > ' " l fabrication. _ l ‘ , j ' ‘ ‘I, '- As an example of the type of lattice-like struc as Other‘objects and advantages will be in‘ part indicated in the following description and in ture to which the invention'relates, reference will part rendered apparent therefrom'. in connection be made to a music bar'or stand wherein ?ve hori '7 ' 1 ' > To enable ‘others skilled in the art so fully to to be held in parallel spaced relation in end standards or uprights.

Moreover, and even tho the bars and their , end pieces were individually ?tted, the prior types‘ of joint'ra'rel‘y were tight enough effectively to constrain the bars and the complete assembly against twisting or from slanting when in use. ‘ ' The present invention undertakes to‘provide more.‘ clearly ‘ the interwoven character of the end standards. ‘ ' - ' Fig. ‘3 is an end view of Fig. 2. i‘ ‘ r The music ‘stand disclosed in Figural repre ‘ sents‘a‘typical application of the herein ‘pro posed method ‘and means of ?rmly clamping a sizes of the‘members and which has a clamping series of rods as to maintain the rod‘s in parallel— ism and the ‘stand as‘ a wholelin an erect non _ slanting position.

The musical, clef it, notes l9, etc., are hung upon the bars a ?rm joint for transversely extending members that automatically compensates for variations in out need for drilling andreaming or the use of auxiliary connectors. To achieve the objectives in view it is proposed to form each of the upright vmembers of the frame of semi-rigid material and in any suitable way. Additional vertical bars, musical symbols, or other characters may be 2,409,366 3 A rods to be clamped therein, the inserting of the rods requires that each recessed portion of the uprights be sprung laterally a slight distance fur ther, and the inherent elasticity of the stock, in tending to return to its normal position, effects mounted upon the bars according to taste or the subject matter being displayed. vThe hori zontals 5-9 are, in the present embodiment, glass rods, and the end standards, musical symbols, etc. are made of plastic materials, such as “Lucite.” a ?rm clamping of each rod at points above and below a horizontal diametral line, notwithstand ing variations that may exist in rod sizes.
