Description

Pool Section 29 Regulation 3.2(2) AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Application Number: Lodged: Invention Title: Security partition system and universal clip for such system The following statement is a full description of this invention, including the best method of performing It known to us: P111ABAU/1207 Wire.8930 BACKGROUND 1. Field of the Invention This invention relates to security partition systems employing wire panels secured to and interconnected by vertical support posts, and is concerned in particular with a 5 universal clip used to connect the panels to the support posts. 2. Description of the Prior Art Conventional security partition systems are prefabricated with standard length wire panels. The wire panels have integral attachment clips at their ends designed to mechanically interengage in pre-positioned slots in the support posts. 10 The partition systems are normally shipped in a disassembled state, and are designed for on site erection. Space limitations at the site may dictate that one or more of the panels be shortened. Doing so necessitates trimming and removing end sections carrying the integral attachment clips, which leaves the trimmed panel edges without a means of attachment to the support posts. 15 The universal clip of the present invention is designed to be attached, at the erection site, to the trimmed edge at either end of a shortened panel to thereby serve as a means for connecting the shortened panel to a support post. SUMMARY OF THE INVENTION In accordance with the present invention, a security partition system comprises an 20 assembly of components, including a plurality of laterally spaced vertical support posts with vertical slots, and a plurality of panels comprised of evenly spaced horizontal and vertical wires bordering square openings. Clips serve to connect the panels to the support posts. The clips comprise: 2 Wite.8930 (i) a front plate configured and dimensioned to span the gap between and to overlap the vertical wires bordering an opening along an edge of the panel, with a finger projecting from at least one side of the front plate and being arranged outside of the panel edge; 5 (ii) a back plate configured and dimensioned to span the gap between and to overlap the horizontal wires bordering the same opening, with peripheral flanges on the back plate mechanically engaging the horizontal wires; and (iii) a fastener interconnecting and urging the front and back plates together, with the finger on the front plate received in the vertical slot of a support 10 post to thereby establish a connection therebetween. Preferably, the front plate is provided with fingers at both of its sides, thus adapting the clip for attachment to either end of the panel. Each finger is preferably hook-shaped for mechanical engagement with the bottom edge of the vertical slot in the support post. 15 The front plate is preferably provided with an additional coplanar side flange adjacent to each finger, with an aperture in the side flange through which a locking pin may be inserted and tapped into place in the vertical slot to retain the finger in mechanical engagement with the bottom edge of the slot. These and other features and advantages of the present invention will now be 20 described in further detail with reference to the accompanying drawings, wherein: 3 Wire.8930 BRIEF DESCRIPTION OF THE DRAWINGS: Figure 1 is a perspective view of an exemplary section of a security partition system in accordance with the present invention; Figure 2 is an exploded view of the clip; 5 Figure 3 is a vertical sectional view on an enlarged scale taken along line 3-3 of Figure 1; and Figure 4 is a horizontal sectional view taken along line 4-4 of Figure 3. DETAILED DESCRIPTION With reference initially to Figure 1, a security partition system in accordance with 10 the present invention is generally depicted at 10. The system includes vertical posts 12a, 12b with vertical slots indicated typically at 14. A wire panel 16 spans the gap between the posts. The panel comprises evenly spaced horizontal and vertical wires 18, 20 bordering square opening. In Figure 1, the left hand side of the panel 16 is shown equipped with standard 15 permanently attached clips 22 serving to secure the panel to post 12a. However, because the distance "X" between the posts is less than the standard length of the panel, the right hand side of the panel has been trimmed, resulting in the standard clips at that side having been removed with the trimmed panel segment. Clips 24 in accordance with the present invention provide the means for securing the timed edge of the panel to the post 12b. 20 With reference additionally to Figures 2-4, it will be seen that each clip 24 comprises a front plate 26 having at least one and preferably two fingers 28a, 28b, projecting rearwardly from each side. The front plate is configured and dimensioned to span the gap between and to overlap the vertical wires 20 bordering an opening along the 4 Wirc.8930 trimmed edge of the panel. When the front plate is thus positioned, its finger 28b is arranged outside of the trimmed panel edge. If the front plate was being positioned along a trimmed edge at the opposite side of the panel, then finger 28a would be arranged outside that edge. The front plate thus adapts the clip for universal application to a 5 trimmed edge at either panel side. A back plate 30 is configured and dimensioned to span the gap between and to overlap the horizontal wires 18 bordering the same opening. Forwardly projecting peripheral flanges 32 on the back plate are arranged to mechanically engage the horizontal wires 18. 10 Fastening means in the form of a threaded screw 34 and nut 36 serves to urge the front and back plates together to thereby attach the clip 24 at the trimmed edge of the panel. The fingers 28 are sized to enter respective vertical slots 14 in the support posts 12a, 12b, and are preferably hook-shaped to mechanically engage the bottom edges of the 15 slots. The front plate 26 is preferably additionally provided with coplanar side flanges 38 adjacent to and above the fingers 28. The flanges 38 have apertures 40 designed to accept locking pins 42. The locking pins are inserted through the apertures and are tapped into place in the slots 14 to thereby lock the fingers 28 into mechanical 20 engagement within the slots. In light of the foregoing, it will now be evident to those skilled in the art that the clips 24 of the present invention are readily attachable to the trimmed sides of the panels, thus making it possible to accommodate on site shortening of the panel lengths. With 5 Wire.8930 finger 28 at both sides of the front plates 26, the clips are designed for universal application to either panel edge. 6
