Deatiled Description of the Invention
With reference to the drawings, wherein like reference numbers designate same or corresponding parts throughout, there is shown in FIGS. 1-8 a clip strip having flexible intermediate support made in accordance with the present invention.
The clip strip 10 is an integrally formed unit in which a plurality of identical clip members 12 are formed on a planar support panel 14. As is shown in FIGS. 2 and 3, the support panel 14 includes a plurality of apertures 16. Each of the apertures 16 includes a pair of generally respectively parallel side edges 18, 20, a transverse lower edge 22, and a curved upper edge 24. Longitudinal edges 26, 28 of the support panel 14 are shown in FIG. 3 to be connected to integrally formed flanges 30, 32.
A lower edge 34 of a support plate 36 is formed integrally on an intermediate portion 38 of the support panel 14. The support plate 36 extends transversely across the aperture 16 between the side edges 18, 20.
In the unflexed or unstressed condition, shown in FIG. 1, the support plate 36 is generally perpendicular to a surface 40 of the support panel 14. An upper portion 42 of the support plate 36 is connected integrally to intermediate portion 44 of the clip member 12.
The clip member 12 has side portions 46, 48 which are generally respectively parallel, an upper edge 50 and a lower edge 52 which preferably has a plurality of teeth 54 that can contact transverse lower edge 22. An upper portion 56 of the clip member 12 is concave when viewed from the direction shown by the arrow 58 in FIG. 4 and a lower portion 60 is convex when viewed from the direction of the arrow 58. In the unflexed condition, shown in FIGS. 1 and 4, the lower edge 52 of the clip member 12 projects snuggly below the surface 40 and rearwardly of an inner wall 15 of the support panel 14.
An upper end 62 of the support panel 14 includes an integrally formed hook 64 which projects from the support panel 14. The hook 64 includes a first portion 66 which is generally perpendicular to the support panel 14 and a second portion 68 which is generally parallel to the support panel 14. The hook 64 may be used to suspend the spring clip strip 10 from an edge of a shelf or some other suitable structure. The hook 64 may be used in conjunction with an aperture 70 formed in a lower portion 72 of a next clip strip 10 to attach the hook 64 of a first clip strip 10 to an aperture 70 of the next clip strip 10 to form a display of extended length. Other suitable means for connecting clip strips together in chainlike fashion are available.
During use the upper portion 56 of the clip member 12 can be used to display various types of merchandise such as merchandise 74 in blister card packages which have an aperture 76 proximate to the upper edge of the card 80 as is shown in FIG. 7. As is shown in FIGS. 1, 7 and 8, the upper portion 56 of the clip member 12 is tapered with a relatively thinner portion 82 at the upper end 84. The tapered portion 56 facilitates installation of the merchandise 74 on the clip strip 10 in an efficient manner.
The clip strip 10 may also be used to display merchandise 86 which does not have an aperture. The end 84 of the clip member 12 is pressed toward the support panel 14 in the direction shown by the arrow 88 in FIG. 8, thereby forcing the end 52 to move away from the support panel 14 and allowing a portion 90 of the merchandise 86 to be slipped under the end 52 as is shown in FIG. 8.
When the end 84 is released the clip member 12 snaps back to the original position and the end 52 bears against the portion 90 of the merchandise 86 and the teeth 54 grip the merchandise 86 in a secure manner. When other end 84 of the spring clip 12 is pressed toward the support panel 14, the flanges 30, 32 prevent bending of the support panel 14 so that even when the support panel 14 is suspended from the hook member 64 and the support panel 14 is otherwise unsupported, pressure against the end 84 of the clip member 12 will cause the support plate 36 to bend, rather than causing the support panel 14 to bend thereby allowing the merchandise 86 to be easily inserted under the end 52 of the clip member 12.
The curved upper edge 84 of the clip member 12 extends beyond the end 24 of the aperture 16 so that continued pressure on the end 84 in the direction shown by the arrow 88 in FIG. 8 will cause the end 84 to bear against portion 40 of the support panel 14. Abutment or bearing of the end 84 of clip member 12 onto the support panel 14 prevents overstressing of support plate 36.
As indicated above, the support panel 14, the support plate 36, the clip member 12 and the flanges 30, 32 are formed as a unitary member. The preferred material is a moldable plastic such as Nylon or a similar material.
The support plate 36 in combination with the concave formation of the upper portion 56 of the clip member 12 allows the upper end 84 of the clip member 12 to be spaced away from the support panel 14 thereby allowing the merchandise 74 to be hooked onto the upper end 82 as is shown in FIG. 7 in a rapid and efficient manner.
As is shown in FIG. 4, in the unflexed and unstressed state, the end 52 of the clip member 12 protrudes below the surface 40 of the support panel 14. The clip member 12 always tends to return to this unstressed state, thereby holding the merchandise 86 securely against the support panel 14. In addition, in the position shown in FIG. 4, the edge 52 which when in use contacts the merchandise 86 is free of the support panel 14 and the entire spring clip 10 is free of any small crevices or spaces which would prevent easy cleaning. The unitary structure of the see-saw spring clip 10 allows it to be completely immersed in cleaning solution for rapid and efficient cleaning.
The support plate 36 is generally rectangular in configuration and preferably is trapezoidal in configuration with a relatively shorter edge 94 connected to the clip member 12 and end portions 96, 98 of a relatively longer edge 100 connected to the support panel 14. A relatively smaller area associated with the end portions 96, 98 in contrast to the relatively larger area associated with edge 94 allows preferential bending of the support plate 36 to occur at the end portions 96, 98 when the end 84 is pressed.
It should be understood that while only selected clip members 12 have been described in detail, each of the clip members 12 shown in the drawings has the same configuration as the clip members 12 which have been described.
The foregoing specific embodiment of the present invention is for illustrative purposes only. Various deviations and modifications can be made within the spirit and scope of this invention, without departing from a main theme thereof.
