Definitions

  • the present invention relates to demountable partition wall systems.
  • the present invention relates to a suspension clip for demountably supporting wall board on a vertically-erected framework.
  • the clips shown in U.S. Patent Nos. 5,060,434 and 5,216,859 are of limited utility and are very different in structure than the clip of the present invention.
  • the clip disclosed in U.S. Patent No. 5,531 ,052 is expected to be of much greater utility.
  • the clip disclosed in U.S. Patent No. 5,531 ,052 still leaves room for improvement, especially in one aspect noted in that patent, namely, the structure of that clip which enables the clip to be affixed to wall board at a site remote from the site at which the wall is to be erected.
  • a clip which can be affixed to the wall board at a remote location enables such economies as the use of automated equipment for simultaneously affixing several clips to a gypsum board panel and the shipping of the panel, having the clips affixed thereto, to the location of the vertical support structure to which the panel is to be mounted.
  • such structure enables the use of a separate crew on site which, for instance, uses a die or other instrument for precisely locating the clips on the panel and applies them to the wall board quickly and accurately for a second crew to use to mount to the vertical support structure.
  • an object of the present invention to provide a clip having structure which facilitates affixation of the clip to a gypsum board panel or other type of wall board at a location other than the location of the vertical support structure to which the panel is to be mounted.
  • This angled bearing surface engages the horizontal support members of the vertical support structure to draw the gypsum board panel tight against the studs of the vertical support structure as a result of the weight of the panel.
  • This camming action helps provide a finished wall in which adjacent gypsum board panels are drawn flush with each other so as to improve the appearance of the wall and which are effectively retained in that flush relationship and tight against the vertical support structure by the downward force on the panels.
  • the camming action which is so important to the appearance of the finished wall results from translation of the downward movement of the gypsum board panel into movement toward the studs of the vertical support structure.
  • This camming action is advantageous not only during the erection of the partition wall but also after the wall is erected so that the wall board is continuously biased toward the studs of the vertical support structure. Continuously biasing the wall board against the studs improves the appearance of the finished wall, resists rattling of the wall board against the studs, and resists the flexing of the wall board.
  • This continuous camming results from the engagement of the angled bearing surface of the clip with the horizontal support members of the vertical support structure.
  • a one piece, or unitary, suspension clip for demountably supporting a gypsum board panel, or other type of wall panel, on the horizontal support member of an erect, or vertical support structure.
  • the clip comprises a substantially flat gang nail plate having a plurality of panel-piercing members extending from one face thereof and a wing, or outwardly extending projection, formed on opposite edges thereof.
  • the wings are bendable from a first position substantially co-planar with the plate to a second position forming an angle relative to the plate.
  • the clip is affixed to the panel when the wings are in the first position and the panel, having the clip affixed thereto, is mounted on the vertical support structure when the wings are in the second position.
  • Each of the wings is provided with a bearing surface for engaging the horizontal support member of the vertical support structure having a convex curve formed along at least a substantial portion thereof for facilitating engagement of the horizontal support member of the vertical support structure by the wing and camming the gypsum board panel to which the clip is affixed into engagement with the studs of the vertical support structure.
  • the wing of the unitary suspension clip of the present invention is provided with raised edges to facilitate the insertion of a putty knife or other bending tool under the wings to bend the wings from their first position to their second position and so that, once the wings engage the horizontal support member of the vertical support structure to which the gypsum board panel is erected, the gypsum hoard panel is easily moved from side-to-side along the horizontal support member, thereby facilitating positioning of the gypsum board panel into close proximity with the adjacent gypsum board panel.
  • the unitary suspension clip of the present invention is provided with a stop for preventing insertion of the tool used for bending the wings from the first position to the second position too far under the clip so that neither the clip nor the gypsum board panel to which the clip is affixed are damaged by the bending tool when the wings are bent.
  • Figure 1 is a top plan view of the unitary suspension clip of the present invention.
  • Figure 2 is a bottom plan view of the suspension clip of Fig. 1.
  • Figure 3 is a side elevational view of the suspension clip of Fig. 1 showing the wings of the clip in the first position for affixing to a gypsum board panel or other wall panel.
  • Figure 4 is a top plan view of the suspension clip of Fig. 1 showing the wings of the clip in both the first and second positions (the latter being shown in phantom lines) for engaging the horizontal support member of a vertical support structure.
  • Figure 5 is a side elevational view of the suspension clip of Fig. 1 showing the wings of the clip in the second position for engaging the horizontal support member of a vertical support structure.
  • the unitary suspension clip of the present invention is indicated generally at reference numeral 10 in the figures.
  • the clip 10 is comprised of a generally rectangularly-shaped gang nail plate 12 having upper 14 and lower 16 portions with a plurality of panel-piercing members 18 extending from one face 20 thereof.
  • the clip 10 is stamped from a piece of galvanized steel.
  • the die utilized to stamp the clip 10 from the piece of metal preferably introduces a twist into each of the panel-piercing members 18 of about 60° (from straight) as they are punched, but the degree of twist is set out for purposes of exemplification, not limitation.
  • the twist of the members 18 functions to increase the "grip" of the clip 10 to a gypsum board panel, and this enhancement can be accomplished with a twist of some (instead of all) of the panel-piercing members and/or with a twist of as little as 5-10° from straight.
  • a gypsum board panel it will be apparent from this disclosure that the clip of the present invention is used to advantage to mount any type of wall board or panel to a vertical support structure.
  • a transverse line of weakness extends substantially across the plate 12 between the upper and lower portions 14 and 16, respectively, thereof.
  • the line of weakness as taught by U.S. Patent Nos. 4, 128,979 and 4,245.448, is formed of a combination of aligned, inwardly extending notches 24 and/or slots 26 cut in plate 12 or in the edges of plate 12 as the case may be, about which plate 12 bends to improve anchorage of the clip 10 to a gypsum board panel 28 (shown in Fig. 4) under applied loads as more completely described in those two patents, the disclosures of both patents being incorporated herein in their entirety by this specific reference thereto.
  • a wing 30 is formed integrally with plate 12 along the opposite edges 32 thereof, e.g., along the long sides of the rectangularly-shaped plate 12, and extends outwardly from edge 32.
  • One edge 34 of wing 30 is angled relative to the long edge 32 of plate 12 and is formed by the channel 36 which extends inwardly from the edge 32 of the plate 12.
  • Channel 36 is formed at an acute angle relative to the edge 32 of plate 12 and extends inwardly therefrom to terminate at a point spaced inwardly from the edge 32 of the plate, thereby forming a part of the line of weakness 22.
  • the edge 34 of wing 30, which will be referred to herein as a bearing surface for reasons set out below, therefore . extends outwardly from the long edge 32 of plate 12 at an angle relative to the edge 32.
  • a second line of weakness is formed in the plate 12 along the long edge 32 thereof by the slots 38 cut in plate 12 from a point near the notch 24 at the inside end of the channel 36, in a direction substantially co-linear with the edge 32 of the plate 12 to a point adjacent the notch 25 formed in the same edge 32 of the plate 12 on the side of wing 30 opposite channel 36.
  • the second line of weakness formed by the slots 38 between plate 12 and wing 30 weakens the plate 12 so that the wing 30, which comprises the portion of plate 12 outside that line of weakness, is easily pivoted by bending from a first position (shown in Figs. 1-3) in which the surface of wing 30 is substantially co-planar with the surface of plate 12 to a second position (shown in Figs. 4 and 5) in which the surface of wing 30 forms an angle relative to the surface of plate 12 and gypsum board panel 28.
  • the wing 30 When in this second position, the wing 30 extends from plate 12 in a direction opposite the direction of the panel-piercing members 18 and from the face 40 opposite the face 20. In this manner, the bearing surface 34 of wing 30 and the surface 40 of plate 12 form an inverted "V,” best shown in Fig. 5, for receiving the edge of the horizontal support member (not shown) of a previously-erected vertical support structure.
  • vertical support structure refers to the wall studs and horizontal support members described in the above-incorporated U.S. Patent Nos. 4,128,979 and 4,245,448, as well as the vertical support structure shown in the above-referenced U.S. Patent Nos.
  • edge 34 of wing 30 rests on the edge of the horizontal support member, thereby supporting the gypsum board panel 28 to which the panel-piercing members 18 of plate 12 are engaged on the vertical support structure, the edge 34 is referred to herein as a bearing surface.
  • the edge of the horizontal support member of the vertical support structure on which the bearing surface 34 rests does not extend all the way to the top of the acute angle formed by the bearing surface 34 and the face 40 of plate 12.
  • the bearing surface 34 of wing 30 functions to pull the gypsum board panel 28 tight against the face of the stud of the vertical support structure as the weight of the gypsum board panel causes the edge of the horizontal support member to slide along the bearing surface 34 upwardly towards the inverted "V," effectively camming the gypsum board panel 28 into engagement with the studs and, coincidentally, into alignment with any adjacent such panels (also not shown).
  • the positioning of the bearing surface 34 of the horizontal support member at- a position in which the edge of the horizontal support member does not extend all the way up into the acute angle formed by the inverted "V" of clip 10 is important for a second reason.
  • An important aspect of this ability of the clip 10 of the present invention to cam the gypsum board panel 28 to which it is affixed into engagement with the studs of the vertical support structure and into alignment with the adjacent gypsum board panel (not shown) is to insure that the bearing surface 34 of the wings 30 rests on the horizontal support member. Further, because of the weight of the gypsum board panel 28 (and the load applied to the gypsum board panel by, for instance, shelving which may be mounted to the finished wall), it is important that the wings of each of the clips affixed to an individual gypsum board panel engage the horizontal support member.
  • the bearing surface 34 is provided with a convex curve 42 along at least a substantial portion of the length thereof.
  • the convex curve 42 along bearing surface 34 serves at least two functions.
  • the convex curve opens up the inverted "V" described above between the face 40 of plate 12 and bearing surface 34 so as to increase the likelihood of "catching" the edge of the horizontal support member when the gypsum board panel 28, having the clip 10 affixed thereto, is erected to the vertical support structure.
  • the second function of the convex curve along bearing surface 34 is to cause the gypsum board panel 28 to be cammed into tighter engagement with the studs of the vertical support structure than is achieved with a straight bearing surface 34.
  • the edges of the wings 30 are bent upwardly, or dished, at reference numeral 44 so that the wings 30 are slightly concave when viewed in the plan view shown in Fig. 1 (convex when viewed in Fig. 2).
  • the side of the wings 30 which is adjacent the gypsum board panel 28 is convex so that the edges of the wing 30 are raised slightly up off of the surface of gypsum board panel 28.
  • These raised, or dished, edges 44 serve at least two functions. First, when the wings 30 are bent from the first position to the second position (Figs.
  • the dished edges 44 facilitate insertion of a putty knife or bending tool (not shown) in the manner described below for use in bending the wings 30.
  • the second function of the dished edges 44 is to facilitate the sliding of the gypsum board panel 28 to which the clip 12 is affixed along the horizontal support member of the vertical support structure (not shown) when erected thereto, the dished edges acting to decrease the resistance to the movement, or sliding, of the cut edges of the wing 30 along the cut edge of the horizontal support member.
  • the clip is affixed to the gypsum board panel 28 at a location remote from the site at which the gypsum board panel is erected to a vertical support structure to form a partition wall.
  • the wings 30 are not quite co-planar with the face 40 of plate 12. Instead, the wings 30 are angled upwardly from a co-planar position by approximately 2° toward the second position as shown in Fig. 5. This slight angling of the wings 30 is shown at reference numeral 46 in Fig. 4.
  • This slight bend 46 toward the second position is accomplished at the time the clip 10 is stamped or when the clip is affixed to gypsum board panel 28. If the latter, the bend is accomplished in a number of ways. Depending upon how weak the line of weakness formed along the edge 32 of plate 12 by slots 38 is, the slight upward bend 46 results from the driving of the panel-piercing members 18 into the panel, i.e., if the plate 12 is considerably weakened along the second line of weakness and affixed to gypsum board panel 28 by application of pressure or impact on the portion of the face 40 of plate 12 other than wings 30, the gypsum board panel under plate 12 is compressed enough that the uncompressed portion of the gypsum board panel causes the wings 30 to bend upwardly from the surface of the gypsum board panel.
  • That upward bend 46 can also be accomplished by interposing a thin piece of metal or other material (not shown) between the wing 30 and panel 28 (but not between the face 20 of plate 12 and panel 28) when the clip 10 is affixed to the gypsum board panel.
  • the wings 30 must be bent from the first position to the second position so that gypsum board panel 28 can be erected to the vertical support structure.
  • the bending of the wings is accomplished by, for instance, inserting a putty knife or other tool (not shown) between the wing 30 and the surface of gypsum board panel 28 to which the clip 12 is affixed and then levering or prying the wing 30 upwardly from the surface of gypsum board panel 28. Insertion of the putty knife, however, can damage the surface of the gypsum board panel or, more importantly, partially pry the clip 10 out of gypsum board panel 28.
  • the face 20 of plate 12 is provided with a stop, in the form of the dimple 48 (best shown in Figs. 2 and 3), located along the second line of weakness at the edge 32 of plate 12, to prevent the putty knife from being inserted too far under the plate 12.
