Definitions

  • the present invention relates to detachable structures for supporting articles on perforated material. It further relates to detachable electric connectors, and also to perforated pre-wired boards for use in connection with said electrical connectors.
  • perforated material refers to perforated sheets and boards of any configuration, with or without solid backing which may be integral with the perforated material.
  • the perforated material may be cut from fibrous material such as hardboard or plywood, or the material may be metal, cardboard, plastic, tile or glass. It may also be an apertured block or comparatively soft fibrous material'such as compressed wood, asbestos and other fibers.
  • the perforations may be disposed in any distribution; utilization of the invention merely requires that. there are at least two appropriately spaced and dimensioned ape'rt-uresori the side of the material to which the support structure is to be attached.
  • the present invention provides a novel and improved support structure which can be rapidly and positively locked to any selected two apertures of sheet material and which can be equally rapidly detached from the sheet material.
  • the attachment is firm and free from any wobble. It will withstand shock and vibration to the limits of military specifications.
  • Such positive locking affords the advantage over support structures as heretofore known that the support structure and the articles supported by it will not become accidentally dislodged and that the support structures may be used on other than vertically mounted panels, such as, for example, ceilings.
  • the invention also provides a novel and improved support structure which does not require an appreciable clearance behind the sheet material.
  • the aforementioned spacers or furring strips are no longer required, but the perforated material can be mounted flat upon a supporting wall for instance, by simply nailing or screwing or even gluing it to the wall.
  • the support structure is attachable to perforated sheet material in two steps.
  • the mounting member (spring clip) of the structure is inserted in any two selected apertures and it will lock itself automatically and positively to the sheet material when the assembly of the structure is completed by the insertion of a locking member (attachment 3,229,239 Patented Jan. 11', 1966 fixture) in the clip.
  • the attachment fixture will not only lock the clip to the sheet material, but will also lock itself in a fixed angular position in reference to the clip and the sheet material.
  • the removal of the mounted support structure from the sheet material is equally simple. Withdrawal of the fixture will unlock the clip and with it the entire support structure.
  • the support structure will automatically compensate Within a wide range for variations in the thickness of the perforated sheet material on which it is mounted. Such variations in thickness cannot be avoided in practice, especially with perforated hardboard and other non-metallic perforated sheet material.
  • the inherent wide tolerance compensation by the support structure of the invention affords the advantage that the firmness of attachment is largely independent of the tolerances observed in the manufacture of the sheet material and of the support structure itself, thereby materially reducing manufacturing costs. Further, inventory requirements are considerably reduced because one type of clip can be used for widely different gauges of sheet material.
  • the attach-- ment fixtures are identical, irrespective whether used with spring clips dimensioned for thin or thick mate rials.
  • the invention also provides for a still further increase of the inherent stability and compensation capabilities of the support structure by providing lateral wings on the spring clips. When the clip is locked to the sheet material, the said lateral wings press against the same, thereby asserting a compensating pressure upon both ends of the clip and further steadying the clip and thus the entire support structure very effectively on the sheet material.
  • the invention further comprises electrical outlets and receptacles designed to afford a concealed prewiring system for perforated boards.
  • the outlets are afiixed 'in selected positions to the rear of a panel or wall, preferably before the same is installed. If and whenever it is desired to install and connect an electrical receptacle 'on the front side of the panel, spring clips are inserted into the perforation holes behind which an outlet is mounted. Subsequently, the receptacle which in this instance constitutes the attachment fixture of the support structure, is-
  • the invention further includes a wall or partition material which is integrally pre-wired for electric power, telephone and intercommunication, all of which can be tapped in any transverse location, and which can further serve for the attachment of mechanical support structures as described.
  • the material consists of a perforated panel to one side of which are adhered one or several conductive strips perforated in registry with the perforations of the panel.
  • Such panel constitutes in effect a pre-wired wall the strips in which may carry the power, light, or communication currents.
  • the current carrying strips may be electrically tapped by receptacles attached to the front or opposite side of the panel in any selected positions by means of support structures according to the-invention thus providing for a rapid, inexpensive and convenient installation.
  • the pre-wired panel of the invention also atfor-ds the advantage that no current carrying parts project from the front side of the panel, or are accessible from the front side by ordinary means, thereby avoiding the danger of accidental contact with current carrying parts.
  • Such panels are most conveniently mounted on furring strips so as to keep the current carrying strips from direct contact with the wall.
  • pre-wired panels just described may be in the form of a laminate, one layer of which is solid and theother layer of which has the perforations .for attachment of electric circuit components.
  • the aforementioned conductive strips are interposed between the two layers.
  • the strips may 'be metallic foil strips produced and attached by any suitable means, including printed circuit techniques.
  • such laminate does not have any current carrying parts on either outside which are accidentally accessible. It therefore forms a self-contained wall or partition structure. Connections can .be made only by inserting spring clips according to the invention into the appropriate apertures.
  • the apertures in the sheet material and the spring clips :used for making electrical connections are so correlated that such connection-making clips can be inserted only ,in apertures associated with electric conductors, and vice-versa, spring clips intended for mechanical mounting cannot be inserted in apertures associated with conductors.
  • the invention provides means by which outside circuit components, such as wires, resi rs, capacitors, etc. can be ⁇ conveniently connected to terminals or wired panels. Such panels may have adhered thereto, circuit patterns as produced, for instance, by printed circuit echniq e
  • the support structures according to'the invention can be inexpensively manufactured by typical mass production operations such as stamping and wire-forming.
  • the basic concept of the present invention resides in providing a support structure which is releasably but firmly and positively attachable to perforated sheet material, by forcing the clip from a normally flexed or bent configuration into a less bent configuration, and by utilizing the resulting elongation of the spatial distance between two locking elements on said clip to move the two elements from positions approximately fitting through two selected apertures in the apertured material into positions protruding beyond the perimeter of the apertures, thus locking theclip to the material.
  • the clip is forced from the flexed condition which it has after insertion in the sheet material into the less flexed condition by an attachment fixture which has a curvature different from that of the clip.
  • curvature as used herein is intended to encompass any curvature that is different from that of the clip, including a straight configuration; of the attachment fixture and acurvature of the fixture opposite to that of the curvature 'of the clip. Such opposite curvature is particularly useful to effect an automatic adaptation of the support structure to different gauges of the sheet material as will appear more fully from thesubsequent description.

  • Strip 12 has on its convex side retaining means for re ceiving and positively retaining the attachment fixture 11 of the support structure.
  • the retaining means may take various designs and shapes, it is only essential that they are capable of retaining the fixture on the clip against the inherent spring action of the clip and that they are extended longitudinally of the strip.
  • the retaining means may consist of a pair of guide tracks extending substantially the length of the strip, but it has been found generally preferable to provide two longitudinally spaced pairs of guide tracks 16 and 17 and such are shown in all the figures.
  • the spring clip according to FIGS. 1B, 2 and 3 has the same locking elements and retaining means as described inconnection with FIG. 1A.
  • the clip has a pair of lateral ears or wings 18 which are bent downwardly in reference to the plane of strip 12 as can best be seen in FIG. 2.
  • the locking member of the attachment fixture of the support structure has a locking portion and .a load portion 21.
  • the locking portion must effect an increase of the spatial distance between locking elements 13 of the clip to perform its locking action.
  • the locking portion must have a curvature different from that of the curvature of the clip in the relaxed or a slightly prefiexed condition'of the clip. More specifically, it may be transversely curved in the same senseas the clip though less, it may be straight or it may be transversely curved in the direction opposite to the curvature of the clip. Such opposite curvature of the locking portion has special advantages in many applications as will be more fully explained hereinafter.

  • Panel 25 is secured to a support 26.
  • panel 25 is directly secured'to its support, for instance, by screws 27,'that is, without providing spacing between the panel and the support as is necessary for support structures as theretofore known.
  • the normal inherent elasticity of perforated sheet material either made of fibrous material or of metal and secured to a wall by means of screws, nails, etc. is amply sufficient to supply the minute clearance required for mounting a support structure according to the invention.
  • the clearance required is not more than the thickness of shoe portion 15 and if the sheet material is of the fibrous kind, the shoe portions 15 will force themselves int-o the fibrous material during the locking operation if for any reason the sheet material is tightly adhered to its support, for instance, due to the proximity of a nail or screw, or the apertures do not extend through the full thickness of the sheet material. More-over, the shoes have a leverage effect which produces separation even if the panel is closely attached to a surface. If the panel is glued to the surface, the tip of the shoes acts both as a lever and as a cutting knife thereby providing the required clearance between the perforated panel and its backing.
  • the first step of the locking operation is to insert a spring clip such as shown in FIG. 1B in two selected apertures 30 and 31 of perforated sheet material 32.
  • the clip can be pressed into the two apertures by hand by preflexing the 'clip to the extent necessary, but it has been found more convenient to use the attachment fixture of the support structure as an insertion tool.

  • the left hand locking shoe is first slid into aperture 30 (see FIG. 9A), then the initial curvature of strip 12 is slight- 1y increased by turning the fixture in clock-wise direc tion as indicated by the arrows in FIGS.
  • strip 12 is flattened thereby causing an increase of the spatial distance between the two locking shoes 13 so that the terminal portions 15 now fully protrude beyond apertures 30 and 31 and underlie the adjacent sheet material (FIG. 9D).
  • sheet 32 is backed by a Wall tightly adhered thereto, the shoes, while moving from the position of FIG. 9C into the position of FIG. 9D, will automatically create the necessary space between the perforated sheet and the backing.
  • the tip of each shoe portion 15 which constitutes, in effect, a knife blade, is located in the gap between the perforated sheet and its backing.
  • lock-ing portion 20a being slightly convex in reference to strip 12 and having the apex of its curvature opposite to wings 18, will exercise its greatest downward pressure upon the trip. portion from which the wings 18 extend.
  • these wings are initially downwardly slanted in reference to the plane of strip 12, they are flattened and the outer edges of the wings will press upon the sheet material at two lines laterally spaced in reference to the longitudinal axis of the clip.
  • the two wings now form a pair of spread legs steadying and stabilizing the clip at its mid portion. Due to the convex configuration of the locking portion, the two ends thereof are now at a greater distance from the surface of the sheet material than the mid portion.
  • the springiness of strip 12 pressed downwardly in its middle portion will cause the two end portions of the strip to move upwardly, that is, toward the respective parts of the locking portion until stopped by engagement of terminal portions 15 with the lower side of sheet material 32.
