MOUNTING 5 Sheets-Sheet 5 May 19, 1964 Filed Dec. 27, 1960 United States Patent 3,133,642 MOUNTING Robert G. Mohr and Donald A. Bice, Kalamazoo, Mich, assignors to Brunswick Corporation, a corporation of Delaware Filed Dec. 27, 1960, Ser. No. 78,501 6 Claims. (Cl. 211-86) This invention relates to a mounting assembly, and more particularly to a mounting assembly for detachably and adjustably securing fixtures to a wall.
The primary object of this invention is to provide a new and improved mounting assembly for adjustably and detachably securing fixtures to a wall.
It has been found desirable in numerous environments to detachably and adjustably secure various types of fixtures to the walls of a room while maintaining the appearance and practicability of permanently installed fixtures. For example, in modern school class rooms many fixtures other than the usual chalkboard and bulletin board are installed on the walls of the rooms. Such additional wall mounted fixtures might include perforated panels, flannelboards, tackboards, an easel board, cabinets, and various racks such as magazine racks, to name but a few. Flexibility in arrangement of such wall mounted fixtures is finding increased favor with modern school administrators, at least in part because fixtures should be interchangeable for adapting each class room to the best possible arrangement for its specific function. However, the mounting arrangement for securing the fixtures to the Wall must be such that the individual fixtures may be easily installed and removed, and when installed they must be attached to the wall in such a manner that they will not be inadvertently disengaged.
A more specific object of this invention is to provide a new and improved mounting assembly for adjustably and detachably securing various fixtures to a wall in such a manner that the fixtures have the appearance and practicability of permanently installed fixtures.
Another object of this invention is to provide an improved bracket for such a mounting assembly.
A further object of this invention is to provide an improved mounting assembly for attaching at least a pair of fixtures to a wall, wherein a plurality of spaced apart upright standards are secured to the wall, each standard having two rows of vertically spaced slots, each fixture having a bracket at opposite ends, and each bracket having a body secured to the fixture and a pair of vertically spaced fingers secured to each body and received in a pair of slots in adjacent rows in spaced apart standards, the
upper finger of each pair having a surface with a first portion engaging the periphery of the upper slot of the respective pair of slots, and a second portion spaced from the body and extending away from the body in a direction toward the other finger. A related object of the invention is the provision of stabilizing members secured to a lower portion of the fixtures and each engaging the adjacent standard.
Other objects and advantages will become readily apparent from the following detailed description taken in connection with the accompanying drawings in which:

While illustrative embodiments of the invention are shown in the drawings and will be described in detail herein, the invention is susceptible of embodiment in many other forms, and it should be understood that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated. The scope of the invention will be pointed out in the appended claims.
The present invention is directed to a mounting assembly in which various units or fixtures may be utilized in a classroom to best supplement the particular teaching technique of the instructor. Furthermore, the height of the units above the floor may be adjusted to best use for the height and dexterity of the student age group normally in the room.
More particularly the invention is, in brief, directed to a mounting arrangement for securing fixtures to a wall by the provision of elongated upright standards, firmly, and preferably permanently, secured to the wall by mounting plates. Each fixture is provided with brackets having fingers received in vertically spaced slots in spaced apart standards. The brackets are so arranged, and co-operate with the standards in such a manner as to assure against the fixture being inadvertently disengaged from the mount ing. Stabilizing members, such as a rubber bumper, or a spring clip, may be attached to lower portions of each fixture for suitably engaging an adjacent standard for aiding in retaining the fixture on the standard. Each upright standard is in the form of an elongated T-shaped bar having a front strip with a rear strip secured to the front strip and attached to the wall by mounting plates. Each standard has two vertical rows of longitudinally aligned spaced apart slots in the front strip on opposite sides of the rear strip. One embodiment of the invention is directed to a mounting for an easel assembly. The mounting arrangement is of such a nature that an easel board may be rotated outwardly from the standards to an inclined position, and is retained in the inclined position by bars rotatably secured to the rear face of the easel board and detachably engaging the adjacent standards.
Referring to the drawings, FIGURE 1 illustrates a portion of a school classroom, and a plurality of fixtures 20 are detachably, interchangeably, and adjustably attached on a wall 21. The fixtures 20 include a chalkboard 22, a perforated board 23, an easel assembly 24, tack boards 25, a flannel board 26, a cabinet 27, and a shelf 28. Numerous other fixtures, such as book shelving and various racks are interchangeable with the fixtures shown. Each fixture is mounted on a pair of equally spaced bases in the form of upright standards 30 secured to the wall 21, as will be more fully described hereinafter.
Each standard 36) has a front strip 31 with a pair of parallel, vertically disposed rows 32 of equally spaced apertures in the form of slots 33 which are longitudinally aligned. Each slot 33 is defined by a peripheral surface 34 in the front strip 31, and all slots open outwardly in the same direction through a front face 35 of the standard 30, and away from the wall. Each standard 30 is in the form of an elongated T-shaped bar having a rear strip 37 perpendicular to and co-extensive with the front strip 31 and fixed to the transverse mid-portion of a rear face 38 of the front strip. The standards 33 may be of any suitable material, and are preferably extruded aluminum members.
The standards are preferably equally spaced about four feet apart. Means are provided for securing the standards 30 to the wall 21 and include spaced apart mounting plates 46 on each standard, each mounting plate having a base plate 41 secured to the wall in any suitable manner as by fasteners such as bolts 42 extending through holes in the base plate and anchored in the wall 21. A pair of spaced apart legs 43 are formed integrally with the base plate 41 and define therewith a bifurcated portion defining a slot 43a snugly receiving the standard rear strip 37. A suitable fastener, such as a rivet or bolt and nut means 44, extends through aligned apertures in the legs 43 and the standard rear strip 37, thereby firmly securing the standard 39 to the wall 21. The pair of legs 43 more firmly and securely mount the standard 30 to the wall 21 as the fastener 44 is only required to carry a'shear load and is not subjected to twisting because the rear strip 37 is snugly received between the legs 43.
Each fixture 20 is provided with a pair of brackets 50 secured to opposite ends of the rear face 51 of the fixture 20. More particularly, each bracket St) has a body 52 with a rear face 53 adjacent the front face 35 of the standard front strip 31, and a front face 54 abutting the fixture rear face 51. Means are provided such as rivets or screws 55 passing through holes in the body 52 for securing each bracket 59 to the respective end portion of the fixture rear face 51. A pair of coplanar fingers 58 are integral with the body 52 and extend transversely therefrom in the same direction. Each pair of fingers 53 is received in a pair of slots 33 in a row 32 for attaching the fixture 20 to the wall 21. More particularly, each pair of fingers 58 has adjacent surfaces 59, each surface having a first portion 60 adjacent to and generally perpendicular to the body 52, and a second portion 61 spaced from the body 52 by the first portion 63 and extending away from the body 52 in a direction toward the other finger of the pair of fingers 58 and terminating in end portions 62 which are more closely spaced than are the adjacent peripheral surfaces 34 of the pair of slots 33. The upper finger of the pair of fingers 53' has its surface first portion 60 in engagement with the peripheral surface 34 of the upper notch of the pair of notches 33 when the bracket 50 and the standard 39 are in normal supporting relationship for attaching the fixture 20 on the wall 21. The surface second portion 61 of the upper finger overlies the rear face 38 of the standard front strip 31 for retaining the fixture 20 on the standard 30, as illustrated by the solid lines in FIGURE 2. Each finger also has an outer end surface 63 opposite the adjacent surfaces 59 and has a flat first portion 64a and a convex second portion 64b. The end surface 63 of the upper finger 53 may abut the upper 4 portion of the peripheral surface 34 of the upper slot 33 when inserting or removing the bracket 50.
Stabilizing members provide means for more securely attaching the fixtures to the standards by retarding vertical movement of the fixtures 20 on the standards 30 and maintaining the fixtures spaced from the standards. As illustrated in FIGURE 5, the stabilizing members may take the form of resilient, friction members such as rubber bumpers 65 suitably secured to the lower portion of fixture 20 and engaging the front face 35 of the standard front strip 31. Or, as illustrated in FIGURE 6, the stabilizing members may also take the form of spring clips 66 having body portions 67 suitably secured to the rear face 51 of each fixture 20, as by rivets 67a, and engaging the front face 35 of the standard front strip 31 to space the fixture 29 from the standard. Each spring clip 66 has a resilient portion 68 integral with the body portion 67, and having a return portion formed with a protruding portion 69 which is interlocked with a side edge 70 of the standard front strip 31, and further providing means for detachably interlocking the lower portion of the fixture 2t) and the standard 30 to even more securely attach the fixture to the standard.
To remove the fixture 20 from the standard 30 the lower portion of the fixture must be pivoted away from the standard so that the lower fingers 58 are removed from the lower slots 33 whereupon the fixture 20 may be elevated slightly until the upper finger end surfaces engage the upper portions of the upper notch peripheral surface and the fixture may then be moved perpendicularly away from the standards 30 to disengage the upper fingers 58 from the upper slots 33. Similarly, in attaching a fixture 20 to a pair of standards 33, the lower portion of the fixture must be inclined away from the standards 30, and the upper fingers 53 engaged in the upper slots 33 and lowered into engagement with the bottom of the upper slots, as illustrated by the dotted lines in FIGURE 2, whereupon the fixture may be rotated toward the standard 30 so that the lower fingers 58 are received in the lower slots 33.
Should the fixture 20 be elevated in the pairs of notches 33 the upper fingers could not be rotated out of the upper slots because of the stabilizing members which prevent the fixture lower portion from rotating toward the standards from the position shown in FIGURE 4.
Should the fixture 20 be moved perpendicularly to the standard front strip 31 the fingers 58 will not be disengaged from the notches 33 because the finger end portions 62 are more closely spaced than the notches 33 and will engage the rear surface 38 of the standard front strip 31, even if the surface second portion 61 of the upper finger should slide up the edge between the upper slot peripheral portion 34 and the rear face 38 of the standard front strip.
FIGURES 9-11 show an easel assembly in which an easel board 75 is rotatably attached to a pair of standards 30. The easel includes an easel board 75 having a pair of brackets 50 secured to opposite ends of the easel board rear face 51 adjacent the top edge of the easel board and received in a pair of slots 33, as previously described. A pair of resilient rods or bars 76 are secured to respective sides of the easel board rear face 51 adjacent the bottom edge of the easel board, each by a bracket 77 which snugly engages a transverse end 78 of a bar 76 and is suitably secured to the easel board rear face 51, as by screws, for mounting each bar for rotation in a vertical plane and against movement in a horizontal plane. Each bar has a bight portion 79 which is urged into resilient engagement with the side edge of the adjacent standard front strip 31 for detachably retaining the easel board in an inclined position. The easel board may be easily rotated to a vertical position in engagement with the standard front face 35 by releasing each bight portion 79 from engagement with the adjacent standard edge 70. Because the easel board 75 is mounted on spaced apart standards 30, the face 51 may be provided with vertically spaced guides 81 for receiving a flannel board, or the like, which may be stored between the standards 30 when the easel board is in the vertical position.
