RESILIENT SLEEVE GI~SS SHELF BRACKET
BACKGROUND_OF TXE INVENTION
This invention relates to shelf support brackets and parti~ularly to brackets of the type that support glass and marble shelves in a cantile~er fashion.
Cantilever shel~ brackets for supporting inserted shelf pan~ls, usually o~ wood, have been known for many years. In recent years, these have taken the form of extruded aluminum devi~es capable of receiving the shelf panel in a wedging action, as in U.S. Patsnt 4,508,301 and 4,385,565. That is, thP wood shelf panel of closely controlled thickness tolerance is placed under slightly deforming wedging stress during insertion, for secure retention of the assembled panel structure. The panel is inserted until the inner end abuts the inner end of the bracket throat. While thi~ works Yery well for certain materials such as wood or particle board, it is not desirable to apply such stresses to certain other materials, particularly glass or marble. BreaXage can result. This potentlal breakage pro~lem is accentuated by the fact that gl~ss panels ~or shel~ing tend to ~ary c~nsiderably in thiakness. Therefore, a thicker panel eith~r will not fit within the throat of the bracket, or, if sufficient forca is applied to wedge it in place, the stress is immediately too great. If a thin panel is inserted, it is not securely retained. Furthermore, the potential of breakage resulting from this stress is increased if any scxatching of the glass occurs. One significant cause o~ such scratching is the abutment engagement of the inner edge of the inserted shelf with the inner end of the bracket throat or of the bracket fastener as during insertion of the panel. Al~ernately, .
o~
1 scratching can occur during the wedging type insertion of the glass panel into the metal bracket.
Aside from protection of glass and marble panels or the like from scratching, marring and localized ~tress, it is sometimes desirable to protect panels of fine wood and other materials during assembly of this shelving structure.
SUMMARY OF THE INVENTION
A primary object of this invention is to provide a cantilaver shelf bracket capable of receiving and retaining a shelf panel such as glass or marble without scratchingl marring or application of localized stress to the panel upon ass~mbly. It is another object of the in~ention to accommodate significant variation in the thickness of tha panel that ~s to be retained. According to the invention, a bracket has a laterally oriented throat and a gensrally U-shaped resilient interface strip fitted over the rear edge and rear portion of the shelf panel and received within the shelf bracket throat. Interlock m~ans are provided between the top of the resilient strip and the throat for restraining movement of the shelf and biasing means on the b~ttom of the resilient ~trip are provid~d for biasing the top of the resilie~t skrip a~d the throat ~ogether. The interface strip has a base portion to protect the rear edge of the glass from abrasion and a pair of sidewalls that convexge away from the base to a dimension less than the thickness of the smallest shelf panel to be accommodated.
The interface strip is preferably placed on the rear portion of the shelf b~fore insertion into the support bracket. This r~duces the likelihood of marring or stressing of the glass during installation. Variation in glass thickness is taken up in the throat portion by the 1 biasing means disposed between the lower portion of the throat and the bottom wall of the interface strip.
These and vther xelated objects, advantages and features of this invention will become apparent upon review of the following spacification in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMEN~
Referring now specifically to the drawings and the illustrative embodiments depicted tharein, the shelf and bra~ket assembly 10 includes a bracket 12, having a resilient lnterface ~trip 14, and cooperative with the rear portlon of a glass shelf panel 16. The ends of the bracket may be covered by a pair of end caps (n~t shown).
1 Bracket 12 pre~erably comprises an elongated metal member formed as an extrusion of aluminum. A vertical rear : :-panel 20 abuts the wall surface and is af~ixed thereto by fastener screws 32 extending through orifices 30 formed in the rear panal. Between an upper overhang 24 and a lower support platform 22 of the bracket is a receiving throat 26.
The upper ov~rhang member 24 has an upwardly rearwardly oriented fascia surface 25 and a generally horizontal support surface 40. Support surface 40 is 1o generally corrugated by the formation of a ~eries o~ detents 39 therein. Lower support plat~orm 22 has a first portion 23 adjacent rear panel 20 that ~o~s the bottom of the receiving throat and a second, outer portion that def~nes an :~
upwardly exkending, downwardly curved, outer support surface 28 and a depression or recess between this sur~ace 28 and rear panel 2Q.
Interface ætrip 14, shown in detail in Fig. 2, is formed o~ a resilient polymeric material, prefera~ly poly~.inylchloride, polyurethane, polyethylene, polypropylene, copolymers or the equivalent tharein, fo~med :~
as by extrusion in a long strip. Interface strip 14 is of a generally U-shape aon~iguration having a base member 41 and an upper compression member 36 and a lower compression member 37 extending from the end~ of the base. The upper surface of upper compression member 36 has a series of ribs 38 that fit within detents 39 in the throat upper support surface 40 when the interface strip is in the braaket throat. A series o~ resilient fingers 34 extend downwardly from the lower surface of lower compres~ion member 37 and slope downwardly away from base portion ~1. Compression members 36, 37 convexge away ~rom base portion 41 and dafine 1 a cavity having an opening that is less than the minimum thickness of the shelf panel to be supported by the invention. Thus, the interface strip will b~ frictionally retained on the rear portion of a shelf panel inserted between upper and lower compression memhars 36, 37.
Referring to Fig~ 1, a shelf panel 16 is shown having an interface strip 14 affixed to its rear portion and inserted within the support bracket 12. Ribs 38 on the inter~ace strip 14 engage detants 39 to provide lateral restraint between the eupport bracket and the interface strip. Fingers 34 are compres~ed b~ween lo~er compression memher 37 and portion 23 of the lower support pla~form placing an upward bias on the interface strip and henae the interface between upper compression member 36 and upper support sur~ace 40. The downwardly, outwardly orientation of fingers 34 additionally increases the re istance of the insert strip to pulling out o~ the throat Z6. ~he upward :~
bias from ~ingers 34 additionally increases the lateral frickion retention force bekween upper and lower compression members 3~, 37 and the shelf plate 16 giving additional resistance against lateral removal.
The line y-y ~n Fig. l demon~trates the centerline or bottom surface o~ an inserted helf panel having a thickness greater than X. The increased thickness will cauee the lower compression member 37 to be located lover in the throat 26. This downwardly offset location of the interface strip is accommodated by lncreased compression of fingers 34. The centerline or bottom surface of the shelf plate is thu~ offset counterclockwise as compared with a less thick shelf. Such an offset would be essentially .
imperceivable to the user and would, there~ore, not be an aesthetic concern. The of~set of the centerline or bottom sur~ace of the panel will alter the point on outer support surface 28 that supports the shelf. The large radius or cam-like curvature of outer suppork surface 28 will accommodate such displacement whil providing reduced stress support for th~ shelf 16, by always providing a contact point that is not a sharp edge.
A modi~ied configuration o~ interface strip 14 is shown in Fig. 3. ~ set of barbs 42 are ~hown extending upwardly fr~m the lower compression member 37 and upwardly rearwardly towards the base portiGn 141. Barbs 42 will flex inwardly of the cavity upon engagement thPreo~ by an inserted rear portion of a shelf panel. Barb~ 42 thu~
provide additional gripping force on the 6helf panel.
Anothar configuration o~ interfaae strip 14 is hown in Fig. 4. The interface str~p i3 a dual durometer laminate with an inner aontact ~urface 44 that i8 relatively soft and r eilient in comparison with an outer mounting surface 46. The purpose o~ this laminate con~truction is to allow a more resilient material to be used in the interface strip to increase the biasing force produced by ~ingers 234 while still pro~iding a soft gripping ~urface ~or interfacing with the shelf panel 16.
An alternative, but not necessarily pre~erred, embodiment of the invention is shown in Figs. 5-7. Support bracket 312 is similar to ~he one in the prior embodiment except that a countersunk ~hreaded aper~ure 51 is ~ormed in lower support platform 322 and an adjustment screw 50 extends through aperture 51 into throat 326. A modified inter~ace strip 314, shown in Fig. 7, is provided. In this embodiment, the upper wall 56 and lvwer wall 58 of the 1 interface strip are made from di~erent durometer PVC
materials or the equivalent. Upper wall 56 i5 of a softer, more flexible polymer and lower wall 58 is of a more rigid pol~mer. Rear wall 60 is an extension of upper wall 56 and is made ~rom the same softer materialO
Fig. 5 shows a shel~ panel having an interface strip on it~ rear portion being inserted into ~ support bracket 312. Resilient upper wall 56 engages upper support surface 340 and rigid lower wall 58 i~ dispo~ed abova adjustment screw 50. Ad~ustment screw 50 is rotated into contact with lower wall 58 ~nd i~ ~urther rotated to bias upper wall 56 into firm engagement with upper support surface 3400 The use of a softer, more ~lexible polymer material in the upper wall increases the int~rloak with th~
upper support surgace to prov~de increased lataral :.
resistance to pulling the shel~ out of the support. The :~
user of a softer, more flexible ~atsrial ~or the rear wall 60 provide~ a cushion between the reax edge of the shelf panel and the support bra~ket to prevent chipping of the rear edge of th~ panel. The rigid lower wall S8 provides a durable surface for interact~on with ad3u~tment screw 50.
The resilience in upper wall 56 and rear wall 60 accommodate~ variations in the thickness of shelf panels.
The adjustability derived from adjustmenk screw 50 accommodates the various thickness panels within the throat portion 326.
Changes and modifications in the speci~ically described embodiments can be carried out without departing fr~m the scope of the invention which is intended to be limited only by the scope of the appended claims.
