COMPLETE SPECIFICATION FOR OFFICE USE Application Number: Lodged: Class: Int. Class: Complete Specification Lodged: Accepted: Published: Priority: 0 -7 49 Related Art: TO BE COMPLETED BY APPLICANT Name of Applicant: SPOTLESS PLASTICS PTY. LTD.
S Address of Applicant: S* Actual Inventor: Address for Service: 20-26 Sullivan Street, Moorabbin, Victoria 3189, Australia Joseph Charles HOLLIS SMITH SHELSTON BEADLE 207 Riversdale Road (P 0 Box 410) Hawthorn Victoria 3122 Australia (Attorney Code SA) Complete Specification for the invention entitled: IMPROVED CLIP The following statement is a full description of this invention, including the best method of performing it known to us: Page 1 Our Ref: #4848 TNB:WB 6spo 1 TITLE: IMPROVED CLIP Field of the Invention: This invention relates to clips, and more particularly to an improved clip which may be integrally moulded from a suitable plastics material such that it may form part of a plastics article such as a garment hanger. However, the clip according to the invention is not limited to use on garment hangers since it may be equally useful in other fields to provide a gripping function for many different forms of articles.
Background of the Invention: Most clips used in the garment hanger industry comprise at least two components: the clip elements, which may be integrally moulded or separately hinged, and a spring biasing element, which may be metal element or a plastics element, which physically engages the clip elements to hold them in a closed gripping :position.
20 The need to manufacture and assemble several components significantly adds to the cost of the hanger and reduces its reliability in the market place.
*In addition to the above, when articles such as garment hangers having clips according to the prior art 25 are loaded with garments and are then stacked for ooo o transport, the weight of the garments and the hangers bearing on each other may often cause undesired opening of the clips whereby the garments are released from their hangers.
Summary of the Invention and Objects: It is accordingly an object of the present invention to provide an improved clip which may be integrally moulded from plastics materials, in a condition ready for use, and which is suitable for integral moulding as part of a garment clip hanger.
It is another object to provide a clip constructed spot#5040 92 10 2 in such a manner as to avoid inadvertent opening in the above manner.
The invention therefore provides provides a moulded plastics clip comprising a pair of legs, each leg having an object engaging free end portion and a connecting end portion, said legs being integrally connected in spaced relation at said connecting end portions by a leaf portion having an elastic memory, integrally moulded latching means capable of engagement to hold said legs in at least one closed position in which said free end portions of said legs are adjacent to each other so as to be capable of gripping an object between said free end portions, said legs further having a predetermined open position in which the free end portions of the legs are spaced apart and face toward each other and define an article receiving opening to receive an article to be gripped by the free end portions of the legs, said leaf portion having a transverse dimension such that said free end portions of said legs are widely spaced apart in said predetermined open position,said leaf portion being in a deformed state when said legs are held in said closed position, said leaf portion operating as a restoring spring to move said free end portions apart and to hold said free end portions in said predetermined spaced apart open position when said latching means is released so that an object may be readily inserted between said free end portions for gripping.
By providing a clip in which not only the hinge is integrally moulded but also the latching means is integrally moulded, a moulded plastics article, such as a garment hanger, may be integrally moulded with one or more clips which are operational when moulded, without any additional machine or manual assembly. In this way, the overall cost of the article is considerably reduced, and the clips do not have detachable spring components which may be detached or lost when in use.
In one preferred form of the invention, said latching means comprises a fixed portion directly or 0* 0a 0 0 a rt~T'~s~ g i 2 i C g~~ spot5848 93 1 2(a) indirectly integrally connected to one of said legs, a manually deformable portion providing releasable latching engagement with the other leg or with an element integrally connected to said other leg, said fixed and manually deformable portions being arranged such that relative movement between said portions is required to release said latch.
By forming the latching means in the above defined manner, the clip is still able to be conveniently released using one hand, but the possibility of inadvertent or undesirable releasing of the clip is substantially reduced. Since the clip according to the above preferred embodiment requires two forces to be applied to it in opposite directions, so as to cause relative movement between the latching components, the 'clips are less likely to be released by stacking forces and the like, which are necessarily in a single direction.
Clips according to the present invention may be 20 moulded from general purpose polystyrene and thus do not require the use of exotic or expensive plastics materials which would significantly erode any cost benefits of the integral constructions.
5 Brief Description of the Drawings: a po..84D 92 i0 1'A 1 3 One presently preferred embodiment of the invention, as applied to a garment hanger, will now be described with reference to the accompanying drawings in which: Figure 1 is a perspective front view of a garment hanger embodying to the invention, Figure 2 is a plan view of one end of the hanger according to Figure 1, Figure 3 is a front elevation of one end of the hanger of Figure 1, Figure 4 is a section on the line A-A of Figure 3, Figure 5 is an end view of the hanger of Figure 1, with cross-bar and hook omitted, and Figure 6 is a fragmentary perspective view of one end of the hanger of Figure 1.
Description of the Preferred Embodiment: Referring firstly to Figure 1, the hanger comprises a cross-bar 10, a hook 11 and a pair of clips 12 disposed at the ends of the cross-bar 10. The hanger is moulded as a single unit from general purpose polystyrene by means of a one-off moulding operation. The hook 11 maintains the hanger in a position in use so that the cross-bar 10 extends generally horizontally. The cross-bar 10 is of a cross-sectional shape having sufficient strength to resist, twisting or bending.
Each clip 12 comprises a front leg 13 and a rear leg 14 joined r) i spcceoafio1 resi/ieAby' an integrally moulded A&-elCiblre leaf 15 arranged towards the upper ends of the legs and having a generally horizontal orientation. The front leg 13 is extended in a rearward direction above the point of connection with the leaf 15 to form a a pawl 16. The upper end of the rear leg 14 extends in forward direction above the point of connections with the leaf 15 to provide a ratchet 17 and a finger and thumb operated latch member 18.
The lower end of each leg is provided with a pair of inwardly directed sharp teeth 19 which extend across the width of each leg to provide a grip for gripping a variety of different garment types which may be engaged by the clips 12 on the hanger.
tbspe.049/spot 90 7 18 4 The opposed teeth 19 define a jaw of the respective clips 12 and the jaws are moved towards a closed position by forcing the opposed legs 13 and 14 towards each other to a position as shown in Figure 5. Squeezing the legs together once a garment is inserted between the jaws causes the ratchet 17 and pawl 16 to co-operate whereby the jaws are held in a first position on the ratchet 17 or a second more secure position as shown in Figure The first position is achieved when the pawl 16 engages the first step 20 of the ratchet 17 whereas the second position is achieved when the pawl 16 engages the second step 21 by the application of a greater force to the legs 13 and 14.
The latch member 18 is formed as an extension of the rear leg 14 and comprises an upwardly extending portion arranged beyond the ratchet 17. Each latch member 18 comprises an outer perimeter portion 22 which encloses a movable member 23 and is supported by arms 22a, 22b extending forwardly from the top of leg 14 on either side of the ratchet 17 (Sigs 2 and The movable member 23 contains the ratchet 17 on the underside thereof. In operation the perimeter portion 22 and the movable member 23 are gripped between a finger and thumb of the user and squeezed in order to release the pawl 16 from the ratchet 17.
e* The movable member 23 is operated by the thumb of the user whereby slight pressure causes the ratchet 17 to move to a slightly raised position to release the pawl 16 from the first step 20 or second step 21 so that the clip 12 reverts to the position shown in Figure 4. b.b re';t~n It should be appreciated that theflexi-bl leaf 15 performs two essential functions, namely: a) hinging of the front and back legs to allow the legs to be squeezed together; re b) providing a high tensile resista ce, frce within the Cvd ue. Ao -f le- e(as-i c nmKemor/ of -f-hi tea mechanical arrangement whereby the legs return to a predetermined wi'dty spaced apart A ,neutral position as shown in Figure 4, when the ratchet and pawl mechanism is disengaged.
The ratchet and pawl mechanism is stiff enough during its arc of travel, to compensate for spring back or relaxation of the tbspe.049/spot 90 7 18 5 clip legs 13 and 14 after squeezing against a garment. This results in a small loss of the original pressure which the legs exert on the garment, but such loss is sufficiently small to ensure continued grip on the garment after the clipping action has been performed. The combination of overall flexibility and springiness of the legs 13 and 14 accommodate a wide variation of garment thickness and texture, while retaining adequate gripping pressure. The additional ratchet position extends this variation even further and it is possible that more than two ratchet positions could be included in the clips 12.
In order to release a garment from the clips, it is merely necessary for a user to provide thumb pressure on the member 23 while placing a finger behind the perimeter portion 22, in which case the pawl and ratchet is disengaged. This is a simple operation which can be readily performed by the user with one Se o* hand using considerably less force than required to release a thick garment from a know a known spring clip. By using S. mechanical advantage, the protective surround or perimeter portion 22 overrides the grip force on the clip legs and ejects the front leg pawl 16 from the rear leg ratchet 17. The clip then springs to the. normal open and ready position as shown in C o '0 -We'e Af ervr I keo (5e Figure 4 A Under normal Use the clip may be operated fully between the extent of its travel without incurring damage.
Furthermore, since the member 23 must be pushed relative to the perimeter portion 22, the likelihood of undesired or inadvertent opening of the clip in use is substantially reduced since forces applied to the clip during stacking of garments supported by the hanger will be in a single direction which does not cause relative movement between the member 23 and the portion 22.
It sh9uld be evident to persons skilled in the art that the o(escribed cbove- -&;a41 clip.Ahange- employs a unique and simple configuration of several mechanical features in a way such as to satisfy a wide range of multifunction requirements. The invention thas provides a much improved garment hanger of the clip-type which may be moulded in plastics material which may be clear or may be tbspe.049/spot 90 7 18 6 coloured so as to be aesthetically appealing. Of course modifications to the above described embodiment may be readily envisaged by persons skilled in the art. As mentioned, the pawl and ratchet arrangement may incorporate additional steps to provide a wider variation in travel between the open and closed positions of the clip 12. Of course the various strengthening ribs which are disclosed in the drawings and not specifically mentioned herein may be varied according to different applications of the hanger to provide strength in the areas needed.
It will be further evident that the invention provides a single piece moulded article ready for immediate use and free of S any post moulding operations or the addition of any other components. The hanger provides a strong self- adjusting grip for a variety of garment thicknesses and textures. It is a simple and gentle action to release the mechanically advantaged clip in order to release a garment from the hanger. The hanger provides strength and durability during normal use and has a fail safe release mechanism during bulk storage or transport of garments. The operation of the clip is a self-evident operation for ready consumer acceptance.
As mentioned above, the clip embodying the invention, forming part of the hanger described above, may be used for many different purposes outside the garment hanger indvstry. Thus, the invention is not in any way restricted to the use of the clip according to the invention on garment hangers.
