The present invention relates to a snap-in glass se-tting construction and, more particularly, to a glassretaining assembly wherein a pair of opposed stop members are secured by resilient spring clips in contact with -opposed marginal portions of the glass sheet.
The present invention is a continuation-in-part of my earlier application Serial No. 629,415, tiled in the United States Patent Office on December 19, 1956.
In this earlier application, I have disclosed an inlproved glass setting construction of the snap-in type and utilizing a pair of generally channel-shaped stop members` adapted to contact opposing marginal portions of The stop mema structural support element and having lateral wing portions inserted in interior grooves formed in the stop members.
authorized persons. Further, an improved glass-support- 'ing element adapted to be interposed between adjacent `spring clips is provided for supporting the weight of the glass sheet, this element being particularly useful where the stop members are utilized to retain the glass bottom edgeof the glass sheet,
It is, therefore, an important object of the present invention to provide an improved` snap-in glass setting construction.
Another importantobject of this invention is the provisionuof an improved glasssetting assembly wherein a pair of stop members are retained in glass-supporting relation` by spring clips contactingspaced portions of at least one of the stop members.
It is a further object of this invention to provide an -improved glass-supporting assembly wherein a pair of elongated stop members are maintained in position by common spring clips, transversely spaced portions of each` stop member being contacted by the clips to secure the elements against undesired movement relative to `one another and relative to a support surface.
Still another object of the present invention is the provision of a glass-setting construction utilizing elongated stop members retained in position by longitu- `dir1ally-spaced sprng clips disposed generally beneath a .glasssheet interposed between the stop members, the
weight of the glass sheet being supported by a plurality .of individual glass-supporting elements interposed between adjacent spring clips. t
. It is yet another important object to providean Virnlsheet in position upon a structural footing or at the` t 2,971,229 Patented Feb. 14,1961
proved glass setting assembly of enhanced resistance to unauthorized entry and including a pair of stop members disposed to either side of a glass sheet, the exterior one of the stop members and the supporting surface on which the stop member is disposed being provided with mating angularly disposed portions inhibiting separation of the members.
These and other objects will be more apparent from the following detailed description of a preferred embodiment of this invention and by reference to the drawings forming a part thereof, wherein:
Figure 1 is a vertical cross-sectional View of a glass setting of the present invention;
Figure 2 is a sectional view taken along the plane 2-2 of Figure 1;
Figure 3 is a perspective view of the improved spring clip of the present invention;
Figure 4 is a view simllar to Figure 1 illustrating a modified form of the present invention; and
Figure 5 is a view similar to Figures 1 :and 4 showing another modication of the present invention.
In Figure 1, reference numeral l@ refers generally to l a glass-setting assembly of the present invention disposed upon a support, such as an architectural structural member il..
To secure the assembly 10 to the support member 11, a base indicated generally at 12 is utilized. This base l2 is secured to the support member 11, as by a plurality of longitudinally spaced screws 13, the screws being spaced more or less uniformly along the length ofthe elongated base 12, which preferably is formedas an aluminum extrusion. The base 12 is provided with a pair of recesses 14 formed in the under surface thereof, which recesses are adapted to be lilled with a suitable sealing mastic or the like 15. Disposed adjacent one longitudinal edge of the base 12 and lying substantially normal to the plane of the base 12 is an upstanding vertical liange i6. This flange is continuous throughout the length o-f the member 12 and is utilized to prevent unauthorized removal of the assembly 10 from the sup- 'port 11, as will be hereinafter more fully explained.
The assembly l() also includes a pair of ident cal stop members 2d and 21. These stop members are preferably elongated extruded aluminum shapes. Since each of the stop members 2i) and 21`is identical, a description of one will be equally applicable to the other.
The stop member 20 includes an upper liange or wall 22, a vertical web or wall portion 23, and a lower ange or Wall 24. It will be realized that the stop members extend the entire lengthof the associated. edge of the glass sheet indicated generally at A, and the individual stop members 2li and 21 will be cut to length from stock strips of the extrusion. The inner longitudinal edge of the upper ange 22 is provided with an enlarged shoulder portion 25 deiining a re-entrant mounting channel 26 within which is disposed a glaze strip of suitable elastomeric sealing material 27. i e sealing material 27 actually contacts the adjacent marginal side surfaces of the glass panel or sheet A.
A seating groove 28 is provided in the upper surface of the lower ange or wall 2d, this groove extending longitudinally ofthe stop member 20 adjacent the inner wall of the vertical web or side wall 23. The upper surface of the lower flange 24 is beveled, as at 29, the wall 29 lying in a plane inclined upwardly from the inner free longitudinal edge 30 of the llange 29 to the groove 28.
The vertical web 23terrninates, as indicated at 31, in
i spaced relation to the base 12, and the web is provided pose` to be hereinaftermore `fully described.
vindicated in Figure 1.
The stop members and 21 are secured by means of centrally located, longitudinally spaced spring clips 35, best illustrated in Figure 3 of the drawings. Each spring clip 35 comprises a central longitudinally extending planar base portion 35 to which outer laterally extending arms 37 areV joined through upwardly and outwardly inclined joining portions 38. Downwardly projecting V-shaped lips 39 are formed integrally with the clip to extend along the respective outer longitudinal edges of the arms 37. Each longitudinal extremity of the adjoining portions 38, respectively, is provided with integrally formed, down-turned flanges or tabs 48, four such flanges being provided for each spring clip.
The base portion 36 of each spring clip is provided with longitudinally spaced apertures 41 adapted to receive the screws or bolts 13 hereinbefore described as interconnecting the base 12 and the support 11. Thus, during assembly, the spring clips are superimposed on the base, with the apertures 41 of the clip 35 being aligned -with the apertures in the base for receiving the screws 13. The securing of the base 12 to the support 11 Interposed between adjacent spring clips 35 standing intermediate flange 49. Superimposed upon the j table surface 46 and adapted to be interposed between the table surface 46 and the bottom edge of the glass sheet A is a cushioning strip 50 formed of suitable material, such as lead or the like.
The cooperation between the various structural elements can best be appreciated from the following description of the assembly procedure.
To assemble the glass-setting elements, a rst necessary step is the positioning of the base plate 12 upon the structural support 11. Prior to the positioning of the base plate, the recesses 14 are preferably filled with the mastic or other sealing material 15, and the base plates will then be placed upon the support 11 in a position as Of course, suitably located holes will be drilled and tapped in the base plate 12 and the 'be utilized for this purpose, if so desired.
The next step in assembly is to position the spring clip in longitudinally-spaced relation along the length of the base plate 12 and to loosely assemble the spring clip thereon, either through the same screw 13 or through separate screws, as may be desired. The necessity for merely loosening the spring clip will be appreciated, since the next step involves the assembly of the outer stop member 20 upon the base plate 12. The presence of the ange 16 upon the base plate 12 prevents the mere lateral sliding ofthe stop member 20 into position beneath' the appropriate arm 37 of the spring clip, andthe Venhanced resiliency of the spring clip 35 will prevent sucient vertical distortion of the appropriate spring clip arm if the spring clip were fastened in its final assembled position as indicated in Figure 1. ABy inserting the leading inner longitudinal edge 30 of the lower flange 24 between the terminal lips 39 of the appropriate spring clip armV and the adjacent flangel, the stop member can then be moved laterally beneath thespring clip arm 37 to assume its po- Y A sition shown irrFigure 1, wherein the ange 16 ofthe base plate 12 is vertically aligned with the recess 34 of the vertical web 23. At thisV time, the pendant lip 39 at the terminal end of the arm 37 of the spring clip 35 will be entered into the groove 28 of the stop member 20. Next, the spring clips are tightened into firm assembly with the base plate 12, thus confining the lower flange 24 of the stop member 20 beneath the appropriate spring clip arm 37.
Next, the glass support elements 45 are positioned intermediate the spring yclips 35, the one dependent leg 48 of the elements 45 being positioned in the groove 28.015 the stop member 2t) and the opstanding flange 49 abutting the depending shoulder 25 of the same stop member 2f). The depending leg 47 contacts the base plate 12 intermediate adjacent spring clips 35.
Next, the glass sheet or panel A is superimposed on the cushion surface 50 of the support element 45. The support elements 45 are stabilized to support the Weight of the glass sheet by means of tbe three point contact of the legs 47 and 48 and the flange 49 with the associated parts of the assembly as heretofore described. More specifically, contact between the flange 49 and the shoulder 25 prevents tipping of the glass support element even though the entire weight of the glass sheet may be imposed thereon.
Next, the stop member 21 is positioned in lateral alignment with the stop member 20, and the outer stop member is moved into position by sliding the lower flange 24 thereof into its illustrtaed position beneath the other spring clip arms 37. The beveled upper surface 29 'of the flange 24 greatly facilitates this assembly operation, and entry of the lips 39 of the appropriate arm 37 intothe groove 28 of the stop member 21 will retain the stop member in its illustrated position.
After the stop members have been assembled, as illustrated in Figure 1, it is obvious that the presence of the angularly-related base plate 12 and the base-plate flange 16, lower flange 24 and opstanding web extension 33 will prevent lateral outward displacement of the stop member 20. The spring resistance of the arms 37 of the clip 35 is such that sufficient vertical movement of the member 20 will not be accommodated to allow vertical clear- -ance between the upper end of the flange 16 and the lower flange or wall 24. Thus, once the spring clips have been secured in position, the stop member 20 cannot be removed by the exertion of an upward or tilting force thereon.
It will be noted from Figure 1 that the downturned flanges or tabs 4f) at each longitudinal extremity of the spring clip 35 contact the upper beveled surfaces 29 'of the lower anges 24 of the stop members 20 and 2l.
Thus, the spring clips contact not only the grooves 28 of each stop member 20, 21, but also the beveled flange surface. In previously suggested designs of this type,
`some tilting movement of the channels 20, 21 relative to Va tool, such as a conventional screw driver, in the slot 34 on the inner stop member 21 and prying the stop member upwardly. The resiliency of the spring clip 35 is such that direct transverse pull will force the lip 39 of the spring clip to ride out of the notch 28 of the stop member. When the inner stop member 21 has been removed, the glass sheet A may be removed and the glass support element 45 removed frompthe stop member 20. The outer stop member 20 may be removed only after complete removal, or at least considerable loosening, of the spring clips 35. Y K i In that embodiment of the. invention illustrated :in Figure 4.ofnthe, drawings, the glassfsetting assembly 10 Vis illustrated as disposed on a modified type of structural supportl member 11a. This support member is provided with an upper lateral support surface 11b whichY terminates in an upturned ange llc. The flange-11e cooperates withtthe outer stop member notch 34 in the same manner as the base plate iiange 16 heretofore described. It will be noted that the entire base plate l2 has been eliminated from that form of the invention illustrated in Figure 4, but the security provided by the ange 16 is still provided by the flange 11C. In this instance, the spring clip 35 is connected directly to the structural suppo'rts 11a by the screws i3. Otherwise, the glass-setting assembly is unchanged.
In that form of the invention illustrated in Figure 5 of the drawings, the base plate 12 has again been eliminated, and the glass-setting assembly is directly disposed upon a support beam or the like 11d. Here, the support beam 11d is not provided with any ange or similar projection for cooperation with the notch 34 of the inner stop member 20. Consequently, this type installation is recommended for interior use in which security against entry by unauthorized persons is of no importance. Once again, the spring clips 3S are secured directly to the support elements lib by screws 13. Otherwise, the assembly is unchanged.
Thus, it will be readily appreciated that the present invention providesran improved glass-setting construction wherein a pair of opposed stop members are secured by resilient spring clips in contact with the opposed marginal portions of a glass sheet. The position of the anges 40 on the resilient spring clips 35 prevents any unwarranted pivotal movement between the spring clips and the stop members 2t), 2i. This construction reduces the danger of accidental displacement of the stop members in the event of high winds or similar forces being exerted upon the glass panel A. Further, the entire assembly is tightened and provides a more secure assembly. The cooperation of the angularly-disposed flanges 16 and llc upon the base plate l2 and the structural member 11a, respectively, will be readily appreciated, since it makes impossible the removal of the stop assembly from the exterior of a building or the like and inhibits the entry of unauthorized persons. The utility of the glass supporting elements 45 will likewise be appreciated by those skilled in the art, since it makes possible the assembly of the glass sheet A with respect to the support element 11, and the base plate 12 (if utilized) and the one stop member 20 prior to the assembly of the second stop member 21.
