URBAIN ETAL BLACKBOARD SETTING SYSTEM 2 Sheets-Sheet 2 Filed April 29, 1957 INVENTORS LEO/V F. UREA/N MATTHEW P- GLOWACK/ This invention relates to chalkboards and tackboards and particularly to mounting and setting systems therefor. j l

As the result of a large surge'in preschool age child populationsliortlylafter World War H there was a need for substantial additional kindergarten and grade school building facilities; These facilities were built and included chalkboards and tackboards where desired. The chalkboards and tackboards were set at a short distance above the floor for use by children of these ages. For example in kindergarten rooms the lower edges of the chalkboards may be set 20 inches above the floor.

As this large group of children progressed through United States Patent "ice the various school grades the demand for kindergarten and lower grade school facilities relatively decreased whereas the need for higher grades and high school facilities increased at a relatively greater rate; In many communities it was desirable to convert kindergarten and lower grade school facilities to higher grade or high school facilities. To accomplish this it was necessary to change the position of the chalkboards and tackboards upon the walls. For example in the upper grades and high school the lower edges of the chalkboards are positioned 30 to 32 inches above the floor to accommodate the taller children as contrasted with a 20 inch placement of the lower edge of a chalkboard in kindergarten rooms.

Prior chalkboard and tackboard setting systems do not lend themselves to ready movement from one height to another. More specifically, the prior setting systems are fastened to the Walls and anchored in such a manner that removal from the walls breaks the chalkboards and tackboards. I Often the walls were actually built around the tackboards and chalkboards whereby to necessitate rebuilding or tearing down of wall sections as the case might be to change the height of the chalkboards.

Accordingly, it is an important object of the present invention to provide an improved chalkboard and tackboard setting system.

More specifically, it is another object of the presentinvention to provide an improved chalkboard and tackboard setting system in which the height of the chalkboards and tackboards can be readily changed upwardly or downwardly to accommodate different sizes of pupils.

Yet another object of the invention to provide a setting system of the type set forth in which the position of the chalkboard and tackboard on the associated wall can be rapidly and economically changed without injury to the chalkboard and tackboard.

Still another objectof the invention is to provide a setting system of the type set forth which is structurally safe and which can be economically and easily installed.

Yet another object of the invention is to provide in a setting system of the type set forth an improved support channel for mounting chalkboards and tackboards. V

A further object of the invention is to provide a chalkboard setting system of the type set forth with improved p These and other objects and advantages of theinvention will be better understood from the following descrip tion when taken in conjunction with the accompanying drawings. In the drawings wherein like reference numerals have been utilized to designate like parts throughout:

Referring particularly to FIGURE 1 of thedrawings, there is shown a chalkboard and tackboard installation generally designated by the numeral 20' and made in accordance with and embodying the principles of the present invention. Installation 20 has been shown as having been made upon a vertical wall 22 and above an underlying floor 24. Forming part of the installation are a tackboard generally designated by the numeral 26 and a chalkboard generally designated by the numeral 28. Tackb'oard 26 and chalkboard 28 are supported on wall 22 above floor 24 by means of the setting system including a plurality of vertically disposed channels 30 mounted on wall 22 and having cooperating top clips 32, intermediate clips 34 and bottom clips 36. There is shown in full lines in FIGURE 1 one preferred position'of tackboard 26 and chalkboard 28 which might be such as to place the lower edge of chalkboard 28 approximately 30 inches from floor 24. V The dashed lines illustrate a lower position for tackboard 26 and chalkboard 28, the lower position being achieved by simple and inexpensive changes in the setting of clips 32, 34 and 36 along channels 30 as will be explained more fully hereinafter.

Tackboard 26 includes in general a tack receiving body or surface 38 which is completely surrounded by a pair of horizontally extending frame members 40 and 42 and a pair of vertically extending frame members 44 and 46. Chalkboard 28 includes a chalk receiving or writing surface 48 which is surrounded and bound by a pair of longitudinallyextending frame members 50 and 52 and a pair of vertically extending frame members 54 and 56. The lower edge of chalkboard 28 is also preferably provided with an eraser and chalk holding tray 58.

In mounting tackboard 26 and chalkboard 28 using the setting system of thepresent invention, atleast two and channels 30-to engage the upper frame member 50 of chalkboard 28. The intermediate clips 34 also engagethe lower frame member '42 to hold and support tackboard'26. The assembly is completed by a top clip 32 mounted on each of channels 30 and engagingthe top frame'member '40 of tackboard 26. i" a Referring particularly to' 'FlGURES" 2 through 6 f the drawings,the constructionof'the channels-orifstandards 30' will be described in detail. Channel 30'includes a main wall or web-60 whi ch may befor exampleeight feet. in length and approximately. one inch in 'Width.

Form'ed on the longitudinally extending edges of'wall '60 are flanges '62 and 64, flanges 62 and 64 extending forwardly from" wall 60 in the mounted position andbeing disposed substantially at right angles therewith. The

' forwardly disposed edges of flanges 62 and 64 have formed thereon and extending therealong inwardly'directed retaining' flanges 66. and 68, respectively. The inwardly directed and confronting edges of retaining flanges 66 and 68 may be spaced apart for example a distance of approximately /f inch. 3 Flanges 66 68 together 'with flanges 6264 and web 60 definea pair of spaced apart grooves or raceways that receive and provide a trackfor various flanges on clips 32 and 34 as will be described .more fully hereinafter.

Formed from the body of wall 60 and extending toward retaining flanges 66 and 68 is a plurality of pockets or sockets 70; The outline of a pocket 70 on wall 60 is substantially U-shaped with the upper edge 72 spaced from the adjacent surface of wall 60 and providing a substantially rectangullar opening to receive a member therethrough. Preferably the pockets 70 are centered in a horizontal directionupon wall 60 as viewed in FIGURE 6 and are spaced therealong at regular intervals with the upper edges 72 of adjacent pockets spaced apart one.

inch. Such a structure will permit variations in height of associated chalkboard or tackboard in increments of an inch.

; A plurality of apertures 74 is provided along the length of wall 60 to receive fasteners 75 therethrough. Any

suitable fastener such as screws, toggle bolts and the like may bensed to mount channels 30 upon the associated wall 22. In mounting chalkboards that are four to six .feet in length, two channels 30 may be used; in mounting chalkboards six to eight feet long, three standards may be 1 used and in mounting chalkboard eight feet and over four or'more channels 30 may be used. Preferably four .anchors or fasteners passing through an associated aperture 74 are provided for each channel 30. Care is taken to insure that the standards 30 are positioned with the longitudinal axes thereof disposed vertically and with the .upper edge 72 of corresponding pockets 70 lying on a commonhorizontal line.

The weight of the tackboard 26 and chalkboard 28 is borne primarily by the bottom clip or bracket 36. Clip 36 includes a substantially rectangular body 76 having a width slightly less than the distance between flanges 6668 to fit therebetween. Struck from body 76 is a pair of locking tabs 78 and 80. Each of tabs 78 and 80 is attached to body 76 along the upper edge of the tab and extends outwardly therefrom and then downwardly substantially parallel to the adjacent surface of clip'body 76.- The width of tabs 78 and 80 is such as to permit them to be inserted through. the opening and into the pockets with the outwardly directed lower surfaces 82 and 84, respectively, resting against and supported by the upper pocket edges 72. The lower surfaces'sl and 84 of the. tabs. are spacediapart the samedistanceasach jacent pocket surfaces 72 so that tabs 78 and can be inserted in adjacent pockets 70.

Formed integral with and disposed substantially perpendicu'lar to body 76is a support flange 86. Flange 86 extends outwardly from body 76in a direction opposite " tothat'of tabs 78 and 80; f'Formedintegral with the outer tending in a direction perpendicular to thesurfaceof body 76 and from body 76' to retaining flange 88.1 An.'aperture 92 is provided in head 9 0'at" substantially the midpoint thereof to receive a pointedmeta'l cutting screw 94 for a purpose which will be explainedmore fully hereinafter.

The construction and'operation' of intermediate clip or bracket 34 is best illustrated in FIGURES 4 and 8 of the drawings. Clip 34 includes a body 96 which may be substantially rectangular in shape and'has a width substantially equal to the width of clipbody 76 described above. More specifically, the-width' of body 96 is such that it can be readily fit betweenthe opposed edges of: retaining flanges 66 and 68 on channels 30: Extending outwardly from the sides of body 96 are retainingflanges 98 and 100 which are disposed at-an obtuseangle preferably of approximately 145 with respect to the surface of body 96. Flanges 98 and 100 are adapted to 'be positioned behind channel flanges 66 and 68 whereby to hold clip 34-within channel 30.

Extending outwardly from the loweredge of'body 96 and disposed substantially'at" an angle of 90 therewith is asupport flange 102. The width offlange 102 is substantially equal to that of body 96 an'dextnding laterally outwardly from flange 102' is a pair of ears 104 and 106. Depending downwardly from the forward or outer edge of flange 102 is a retaining flange 'or prong 108. Ears 106 and 108 are provided on the forward edges thereof with upwardly'extending retaining flanges or prongs 110 and 112, respectviely. Formed substantially in the center of body 96 is an aperture 114.1 1 v v The top bracket or clip 32 includes a-body 116 which is substantially rectangular in shape and has a width substantially equal tothat of body 76 of clip 36 and'body 9 6 of clip 34. Extending laterally outwardly from the longitudinallyextending edges of body 116 adjacent to the upper end thereof are retaining tabs or'flanges 118 and and l20. Preferably flanges 118 and 1205 are offset rearwardly'with respect to body 116 whereby flanges 118 and 120 can fit behind channel flanges 66 and 68 after installation as is illustrated in FIGURES 2 and 3 of the drawings. A second pair of outwardlyextending retaining flanges 122 and 124 is formed onbody 116 adjacent'to the lower end thereof,=flanges 122 124 also being offset rearwardly as are flanges 118-"120. Formed integral with the lower end of body 116 arid-extending forwardly position along channel 30.' To this end an embossed portion substantially circular 'iri'shape is provided in body 116 substantially centrally thereof and formed in the centcr of embossed'po'rtion130 is'an ape'rture 132. Aperture i8 ad ptedior cei ia metal u ng sc ch a SQ 34 RIHGQR .13 of. th dra ing T p. ange .126 of clip 3 2 is also providedwithan embossed or'raised portion 136 formed substantiallyl centrally thereof and extending in the same; direction as body 116. There is provided in the center of embossed portion 136 an aperture 138 adapted to receive; pointed metal cutting screw 140 (see FIGURES 2; and 3 of the drawings). A

The assembly of'the setting system will now be described in detail. l Standards 30 are first mounted upon the verticalwall -22 by means of suitable fasteners such as screws 75 passing through apertures 74 formed in channel -webs 60.; Otherjsuitable fasteners such as bolts, toggle bolts or thelike xrnay' be used. -Preferablythe standards 30 are positioned withihe, lower ends thereof disposedon :prnear thejassociated floor 24 and 'arecarefully aligned so that the center lines thereof are disposed vertically. Care also -is;exercised toinsure that the upper edges 72 of corresponding pockets 70 on all channels are in'horizontal' alignment so that the chalkboards and tackboards mounted thereon will be aligned.

-A bottom clip 36 is then placed ina selected pocket 70 on each of the standards 30. More specifically, the upper surface of support flange 86 on clip 36 is positioned at the level at which the lowermost edge of the associated chalkboard 28 is to be placed. Mounting offclips 36 in position-is accomplished by moving body 76 into channel 30 between flanges 66 and 68. Tabs 78 and80 are then moved downwardly into adjacent pockets 70 with the lowerrearwardly disposed surfaces 82 and 84 of the tabs resting upon edges 72 of the associated pockets. It will be seen from FIGURE 5 that tabs 78 and 80 are securely held in pocket 70 whereby securely to mount bottom clip 36 upon associated channel 30. Care is taken that each bottom clip 36 is positioned at the same level on the various standards 301which are to receive the chalkboard.

Chalkboard 28 is then' placed in position with the lower frame member 52 disposed downwardly in bottom clips 36 and held therein between body 76 and retaining flange 88-. Preferably the distance between the adjacent surfaces of body 76 and flange 88 is substantially equal to the width or thickness of frame member 52 as viewed in FIG- URE '5. Thereinforced support flange 86 is sufiiciently strong to, hold its share of the weight of chalkboard 28.

The intermediate clips 34 are next placed in position if a tackboard 26 is to be positioned above chalkboard 28 in thefinished assembly. During the positioning of clips 34, the chalkboard is completely supported by the bottom clip's 36 and care need be exercised only to see that chalkboard 28 is not tipped forwardly at the top away from channels 30. Clips 34 are moved into position, by lifting them upwardly to the top of the associated channel; 30; and moving them toward wall 22 until the outwardly directed flanges 98-100 lie behind the channel retaining flanges 66 and 68 and within the grooves or raceways formed thereby. Clips 34 can then be slided downwardly within channel 30 with the support flange 102 extending outwardly between the edges of channel flanges 6668. As can be best seen from FIGURE 4 of the drawings, the distance between the inwardly disposed face of retaining flange 108 and the outer surfaces of flanges 66 and 68 is such as to receive and hold therebetween the top frame member 50 of chalkboard 28. With the intermediate'clips 36 in operative position, the chalkboard 28 is fully supported. If for some reason the tackboard 26 is not to be installed immediately, a suitable fastener such as a'metal cutting screw can be put through aperture 114 to clamp clips 36 in position to hold chalkboard 28. 1

Tackboard 26 can next be assembled, any fasteners passing through apertures 114 and clip 36 being first removed. The lower frame member 42 of tackboard 26 is mounted upon clips 36 and moved downwardly between retaining flanges 112 and body 96. The distance between these members is such as to receive and accom- ,modate lower frame member-{ 42. Since intermediate clips 36 are free to slide alohg chaiifiels 30, all thewiglft of tackb oard '26 transferred tothe bottom clips 36'.

Top clips 32 are next placed iii position. This accomplished by movihg eachlclip 32 .to the top of the as ociated'channel 30 and placing; the flanges 118120 and 122 124 behind channel flanges 66 and 68. 'The 32 can then be moved'downwardlywithinchannel 30 withtop flange extending outwardly between the opposed edges of retaining 66- 68. Clips 32 are moved down until the top flanges 1 26 overlie the top .of tackboard frame member with flanges 128 extending downwardly in front thereof. This construction serves to hold tackboard26 against the associated channels 30. The entire assembly is then locked against vertical movement by placing metal cutting screw 134 in position and tightening it against the web 60 of the associated chan- .30:

Me ans is provided to lock the chalkboard 28 and the tackboard 26 against lateral movement with respect to the standards 30 andclips 32, 34 and 36. Tackboard 26 is locked against lateral displacement by means of the pointed metal cutting screws which pass through embossed portion 136 and biteinto the top of frame member 40 v "Screws 140 therefore positively prevent lateral moyementof tackboard 26 with respect to standards 30.

Pointed metal cutting screws 94 are provided on bottom clip '36 to lock chalkboard 28 against lateral displace- .ment. More specifically, screws 94 pass through aperof chalkboard 28 with respect to standards 30.

If it is desired tochange the position of chalkboard 28 and tackboard 26 upon wall 22, this can be readily done.

Asviewed in FIGURE 1 of the drawings, there is shown in dashed lines the method in which chalkboard 28 and tackboard 26 can be moved to a lower position. The screws 134 are first loosened and chalkboard 28 and tackboard 26 moved upwardly together with clips 34 and 32 whereby to disengage and free clips 36. Clips 36 are then placed at the desired height by inserting tabs 78-80 into appropriate pockets 70. The chalkboard 28 is then lowered until frame member 52 is again resting upon clip 36 and more specifically support frame 88 thereof. Movement of chalkboard 28 to the lower position will permit intermediate clips 34 and tackboard 26 to be lowered. Top clips 32 will also move downwardly and can then be pressed into final position. If needed or desired, the screws 94 and 140 can be withdrawn after which top clip 32 can be clamped in the final position by tightening screw 134. Screws 94 and 140 can again be tightened to clamp tackboard 26 and chalkboard 28 against lateral displacement.

The described adjustment of the position of the various parts has been accomplished with a minimum of effort and time. There has been no injury to any of the parts and particularly to the relatively expensive tackboard 26 and chalkboard 28. Any desired adjustment in increments of one inch or multiples thereof can be made in the manner described above. The raising of chalkboard 28 and tackboard 26 can be accomplished by the above described method by simply reversing the direction of movement of the parts after lifting the chalkboard and tackboard to the new elevated position.

There is shown in FIGURE 10 of the drawings the manner in which the setting system of the present invention can be utilized to mount the chalkboard 28 without an associated tackboard. The standards 30 are mounted on wall 22 in the manner described with respect to FIG- URE 1. Bottom; clips 36 are placed in position on channels 30 and chalkboard 28 positioned thereon. Top clips 32 are then moved into channels 30 and downwardly to engage and restrain the upper frame member 400i chalkboard 28. Upon tightening of screws 134 and screws 94 @1 46, installation of chalkboard as is completed.

The; position'of chalkboardzs vertically along wall :22 is readily adjusted in a manner similar "to that described above. For example if it is desired'to raise chalkboard'28 to the position illustrated in dashed lines, screws 94, 140 and 134 are loosened. ChalkboardZS is then lifted sliding top clips' 32' upwardly therewith. Bottom clips 36 are then'moved and engaged the new posif tion'and chalkb'oard'28 lowered thereon. Top clips 32 "are next 'pushed downwardly to engage frame member 140 andare fixed inv that position by tightening screws 134;" Screws 94 and 1'40'are then tightened to prevent 'lateral displacement of chalkboard 28, with respect to standards '30. e Y
