DETAILED DESCRIPTION

[0044] As shown in FIGS. 1-6, a molded plastic ring clip 10 has a first arm 20 and a second arm 30. The first arm 20 has a first end 22 and a second end 24. The second arm 30 has a first end 32 and a second end 34. The arms 20, 30 are substantially C-shaped such that when the respective first and second ends 22, 32, 24, 34 of the first and second arms 20, 30 are brought together a ring shape is defined. The first arm 20 and the second arm 30 are connected at respective first ends 22, 32 by a hinge 40.

[0045] The hinge 40 is a living hinge and extends between an inner surface 21 of the first arm 20 and an inner surface 31 of the second arm 30. The hinge 40 extends for the lateral extent of the ring clip 10. Thus the term lateral is used to define the dimension along the hinge 40 of the ring clip 10.

[0046] The first arm 20 has a first tab 50 extending from the second end 24 of the first arm 20. The first tab 50 is elongate and extends for about half the lateral extent of the first arm 20. The first tab 50 extends in the plane of the second end 24 of the first arm 20. This is best shown in FIG. 3, where an outer surface 23 of the first arm 20 is substantially parallel with an outer surface of the first tab 50.

[0047] The second end 24 of the first arm 20 defines a recess 26. The recess 26 is U-shaped in cross-section, such that the second end 24 of the first arm 20 is split into an inner limb 27 and an outer limb 28. The recess 26 has a divergent mouth 25, defined by the ends of the inner and outer limb 27, 28. A projection 22 extends from the inside surface of the outer limb 28 at the end of the first arm 20 into the mouth 25.

[0048] The second arm 30 has a second tab 60 extending from the second arm 30. The second tab 60 is elongate and extends for about half the lateral extent of the second arm 30. The second tab 60 extends from an outer surface 33 of the second arm 30.

[0049] The first and second tabs 50, 60 are substantially misaligned laterally. This is best seen in FIG. 2, where the first tab 50 extends laterally from a proximal edge 12 of ring clip 10 and the second tab 60 extends laterally from a distal edge 14 of ring clip 10.

[0050] The second end 34 of the second arm 30 is tapered such that it terminates in a point 38. The second end 34 of the second arm 30 defines a first barbs 35, a second barb 36, and a third barb 37. The three barbs 35, 36, 37 are arranged for sequential engagement in the recess 26 to progressively close the ring clip 10. The projection 22 extending from the inside surface of the outer limb 28 at the end of the first arm 20 provides a snap fit connection with the second arm 30 in a closed condition. In the closed condition, a slot is defined between the first and second tabs. In the closed condition, the first and second tabs 50, 60 are substantially opposed.

[0051] In use the ring clip 10 is wrapped around adjacent wire mesh panels such that wire from two or more panels passes between the space defined between the arms. Holding the first tab 50 securely with a forefinger, the second arm 30 is moved towards the recess 26 in the first arm 20 by pressure applied by the thumb on the second tab 60, the second arm 30 hinging relative to the first arm 20 about hinge 40.

[0052] Continued pressure on the second tab 60 to squeeze the first and second arms 20, 30 together results in the second arm 30 being guided by the inner surface of the first tab 50 towards the mouth 25 of the recess 26.

[0053] The tapered end of the second end 34 of the second arm 30 passes through the mouth 25 of the recess 26, causing the inner and outer limb 27, 28 of the first arm 20 to resile as the cross section of the tapered end increases at the first barb 35. Once the first barb 35 has passed the projection 22 at the mouth 25 of the recess 26, the inner and outer limbs 27, 28 of the first arm 20 resile back to their original position, locking the second end 34 of the second arm 30 in the recess 26.

[0054] The ring clip 10 is now closed about the wire mesh panels, in the ring clip 10 closed condition. The first and second tabs 50, 60 are misaligned laterally and there is a lateral spacing between the first and second tabs 50, 60.

[0055] In the closed condition, the ring clip 10 retains a portion of wire 170 associated with each wire mesh panel (see, e.g., FIGS. 7 to 9). The space defined within the closed ring clip 10 may be reduced.

[0056] Further pressure on the second tab 60 presents the second barb 36 to the projection 22 at the mouth 25 of the recess 26, which again causes the inner and outer limbs 27, 28 to resile. Once the second barb 36 has passed the projection 22, the inner and outer limbs 27, 28 of the first arm 20 resile back to their original position, locking a further portion of the second end 34 of the second arm 30 in the recess 26, thus reducing the space defined between the first and second arms 20, 30.

[0057] Yet further pressure on the second tab 60 presents the third barb 37 to the projection 22, which again causes the inner and outer limbs 27, 28 to resile. Once the third barb 37 has passed the projection 22, the inner and outer limbs 27, 28 of the first arm 20 resile back to their original position, locking yet a further portion of the second end 34 of the second arm 30 in the recess 26, thus further reducing the space defined between the first and second arms 20, 30.

[0058] The ring clip 10 may be released from the closed condition to an open condition as follows. Pressure is applied to the inside surface of first tab 50 to open the constriction at the mouth 26, as the first tab 50 acts a lever. Simultaneous pressure on the inside surface of second tab 60, to draw the second arm 30 away from the first arm 20, results in the second arm 30 hinging about hinge 40 and withdrawing the first barb 35 through the now widened constriction in the mouth 25.

[0059] The opposed twisting pressure may be applied using the forefinger and thumb in the opposite sense compared to that described above with respect to the process for closing the ring clip 10. Simultaneous pressure to the respective inside surfaces of the first and second tabs 50, 60 may be easily applied due to the lateral misalignment of the first and second tabs 50, 60 and the lateral spacing therebetween.

[0060] Alternatively, a tool with a flat face, such as a coin, may be inserted into the slot defined between the first and second tabs 50, 60 in the ring clip closed condition. Twisting of the tool applies opposed pressure to the first and second tabs 50, 60 to release the ring clip 10.

[0061] The ring clip 10 may be formed from plastic. The ring clip 10 is a one-piece molding.

[0062] A cover 100 has a first cover plate 120 and a second cover plate 130 (see FIGS. 10a to 17d). The first cover plate 120 and second cover plate 130 are identical, such that only the first cover plate 120 shall be described in detail. The first cover plate 120 has an inner surface 121 and an outer surface 122. The inner surface 121 has two vertically aligned barbed projections 123. The inner surface 121 has two vertically aligned housings 124. The housings 124 each include ramped protrusions 125. The housings 124 each include two horizontal wire guides 127. The horizontal wire guides are on opposed upper and lower sides of the housings 124 respectively. The housings 124 each include two vertical wire guides 128 on the same lateral side of the housings 124 respectively. Thus the two horizontal wire guides 127 of the vertically aligned housings 124 extend toward one another, and the two vertical wire guides 128 extend in the same lateral direction, toward the geometric center of the first cover plate 120.

[0063] Each barbed projection 123 is horizontally aligned with a respective housing 124. The barbed projections 123 and housings 124 are arranged about the geometric center of the first cover plate 120.

[0064] The inner surface 121 has two spacers 126. Each spacer 126 is located between a respective barbed projection 123 and a housing 124. Each spacer 126 is provided with two vertical wire guides 129, extending in opposite lateral directions. A first of the two vertical wire guides 129 extends laterally towards the barbed projection 123, and a second of the two vertical wire guides 129 extends laterally towards the housing 124.

[0065] The horizontal wire guides 127 and vertical wire guides 128, 129, of the housings 124 and spacers 126 are tapered. Between the horizontal wire guides 127 of the upper and lower surfaces of the housings 124, a V-shaped slot 130 is defined, (shown best in FIG. 12). Similarly, between the vertical wire guides 128, 129 of the housing 124 and spacer 126 a V-shaped slot 131 is defined (shown best in FIG. 13). It is to be understood that a first V-shaped slot 131 is defined between the vertical wire guides 128, 129 of the housing 124 and spacer 126 of the same, i.e. first cover plate 120, whilst a second V-shaped slot 131 is defined between the vertical wire guide 129 of the spacer 126 of the first cover plate 120 and the vertical wire guide 128 of the housing 124 of the second cover plate 130, as the first and second cover plates 120, 130 are brought together.

[0066] In use, the first and second cover plates 120, 130 are arranged either side of a wire mesh panel (see FIGS. 15 to 17d), with their respective inner surfaces 121 directly opposed. The first and second cover plates 120, 130 are aligned with the wire mesh panel 160 such that the wire elements are inserted into the V-shaped slots described above. The cover 100 is thereby attached to the wire mesh panel 160 by friction. As shown in FIGS. 17a and 17d, the wire elements may be inserted into the V-shaped slot defined by both the horizontal wire guides 127 and vertical wire guides 128. Alternatively, as shown in FIGS. 17b and 17c, the wire elements may be inserted into the V-shaped slot defined by the horizontal wire guides 127 only.

[0067] To secure the cover 100, the first and second cover plates 120, 130 are pressed together, such that each barbed projection 123 engages with the ramped protrusion 125 of the respective housing 124, the barbed projection 123 resiling as it passes over the ramped protrusion 125 to clamp a wire mesh panel 160 between the first and second cover plates 120, 130 with a snap fit. The wire mesh panel 160 may be part of a wire cage.

[0068] The cover plate 100 may be used to display information regarding the contents or the maintenance of the cage. The labelling may provide a warning.

Instead, this application is intended to cover any variations, uses, or adaptations of the disclosure using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this disclosure pertains and which fall within the limits of the appended claims.
