Description

FIELD

The present disclosure relates to clips used to support objects such as frames including picture frames and posters from walls or structure.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Clips which are inserted into picture or similar frames are known which provide a mount or engagement element that allows the clip to engage a frame such as a picture frame and to be supported by a structure such as a wall using a wire, hook, or similar device. Known clips allow for placement of the clip at varying locations along the frame, but frequently provide this function by biting into or yielding the material of the frame at a desired location. This damages the frame and makes continued adjustment of the clip location difficult.

In other known designs, the clip does not engage with the frame, but is merely positioned at a desirable location. The clip can subsequently slip from the desired location. This problem has been resolved by insertion of a fastener through the clip and frame, however, this solution introduces an additional part which can detrimentally affect the appearance of the frame, and also permanently damages the frame.

DETAILED DESCRIPTION

The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

Referring to FIG. 1, a hanging clip 10 is created as a homogenous molded plastic body which includes a semispherical-shaped head portion 12 having first and second legs 14, 16 extending from the head portion 12. Each of the first and second legs 14, 16 has an extending flange 18, 20 with a convexly curved upper surface 22, 24, and a flat surface 26, 28 facing away from head portion 12. A through-aperture or eyelet 30 is created in portion 12. A gap 32 between first and second legs 14, 16 defines an angle α. According to several embodiments angle α is approximately 8 degrees, however other angles both greater and less than 8 degrees can be used within the scope of the present disclosure. Angle α is created during the molding process so that the first and second legs 14, 16 can be elastically deflected to provide a biased condition when the first and second legs 14, 16 are moved toward each other during installation. Head portion 12 is not limited to a semi-spherical shape and can be provided in other geometric shapes at the discretion of the manufacturer.

Referring to FIGS. 2-4, a neck 34 is provided between portion 12 and the flanges 18, 20 defining a junction 36 with portion 12 and a junction 38 with flanges 18, 20. According to several embodiments, neck 34 can be a smooth, circular or curved surface. According to several embodiments, clip 10 has a total height “A” of approximately 0.74 in (1.88 cm), a length “B” of neck 34 is approximately 0.03 in (0.08 cm), and the flat surfaces 26, 28 are spaced at a distance “C” of approximately 0.16 in (0.41 cm) from an end 38 of neck 34. Clip 10 can also have a total width “D” of approximately 0.24 in (0.61 cm) and aperture 30 of portion 12 can have a through diameter “E” which can nominally be 0.19 in (0.48 cm), but which can vary depending on the wire or hook size which will be received by aperture 30. As best seen in FIG. 4, flanges 18, 20 can extend beyond a perimeter of portion 12.

Referring to FIGS. 1 and 5-6, clip 10 is adapted to be received in an extruded frame member 40, made for example from a metal such as aluminum or steel, or from a polymeric material. Frame member 40 includes opposed inwardly curving arms 42, 44 which define a cavity 46 adapted to receive flanges 18, 20 of clip 10. Inner opposed walls 48, 50 define a channel 52 adapted to receive legs 14, 16. Channel 52 is closed at one end by a wall 54 having a V-shaped notch 56. According to several embodiments, frame member 40 has a total height “F” of approximately 1.0 in (2.54 cm), a total width “G” of approximately 0.61 in (1.55 cm), an opening width “H” between arms 42, 44 of approximately 0.25 in (0.63 cm), a wall locating dimension “J” of approximately 0.35 in (0.89 cm), and a wall-to-wall spacing “K” of approximately 0.2 in (0.51 cm). A width “L” and a depth “M” of notch 56 can be approximately 0.02 and 0.01 in (0.05 and 0.02 cm) respectively. According to several embodiments, notch 56 defines an angle β of approximately 90 degrees. As further shown in FIG. 6, a wall thickness “N” can be universally provided for wall members of frame member 40. The above noted dimensions are not limiting to the disclosure and can be varied at the discretion of the manufacturer.

Referring more specifically to FIG. 5, frame members 40 define mirror image halves rotated about a vertical centerline 53 and also rotated about a horizontal centerline 55. This geometry provides equal and opposed cavities 46, 46′ and opposed channels 52, 52′, such that clips 10 can be received in either or both cavities 46, 46′ and channels 52, 52′.

Referring to FIG. 7, clip 10 can be installed by slidably inserting first and second legs 14, 16 into frame member 40 with first and second legs 14, 16 positioned parallel to channel 52 and with flanges 18, 20 also parallel to channel 52 and therefore not in substantial contact with the inner walls of cavity 46. Clip 10 can then be longitudinally, slidably moved to a desired position along channel 52. When clip 10 is inserted, portion 12 extends freely away from frame member 40. One or more clips 10 can individually be positioned at any longitudinal position within cavities 46, 46′ and channels 52, 52′.

Referring to FIGS. 1, 5, and 8, when the desired position of clip 10 is reached, clip 10 is rotated approximately 90 degrees, for example by manually grasping and rotating portion 12. Clip 10 is rotated until the convexly curved upper surfaces 22, 24 of flanges 18, 20 contact the inward facing walls of arms 42, 44 within cavity 46. Contact between flanges 18, 20 and the inward facing walls of arms 42, 44 can also promote a downward displacement (as viewed in FIG. 8) of clip 10 until surfaces 26, 28 frictionally contact cavity 46 facing surfaces of outwardly directed portions 48a, 50a of opposed walls 48, 50. Frictional contact can also occur between first and second legs 14, 16 and walls 48, 50 by elastic deflection of first and second legs 14, 16.

As angle a decreases, the biasing force created increases a frictional engagement of first and second legs 14, 16 to further assist retention of clip 10. The neck 34 separating semispherical portion 12 from first and second legs 14, 16 provides a rotational sliding contact surface with the free ends of arms 42, 44 to promote rotation of clip 10 during installation. Because contact of the free ends of arms 42, 44 with neck 34 also provides support for clips 10, neck 34 further promotes frictional engagement of clips 10 with frame members 40. First and second legs 14, 16 can include smooth, rounded outward facing surfaces to reduce rotational friction between the first and second legs 14, 16 and the opposed walls 48, 50 when the first and second legs 14, 16 rotate. A curvature of each of the arms 42, 44 can be the same as a curvature of the convexly curved upper surfaces 22, 24. A curvature of each of the arms 42, 44 can also be varied at the discretion of the manufacturer from a curvature of convexly curved upper surfaces 22, 24. This difference in curvature permits frictional contact between extending flanges 18, 20 and arms 42, 44 to be increased or changed by increasing a surface area of convexly curved upper surfaces 22, 24 in contact with arms 42, 44 as the clip 10 is rotated from an installed to an engaged position.

Referring to FIGS. 1 and 9, two or more frame members such as vertical member 40 and a horizontal member 40′ can be connected using one or more joining members 58 to create a frame 60. With semispherical portion 12 extending as shown to the right in FIG. 9, a hook member or loop of wire 62 can be inserted through the eyelet 30 in one, or individually in a plurality of clips 10 to hang frame 60 to a wall or support surface (not shown). As further shown in FIG. 9, one or more clips 10′ can be similarly received and frictionally retained by horizontal frame member 40′, which allows clip(s) 10′ to be vertically oriented to support frame 60.

It is further noted that the geometry of semispherical portion 12 is provided for example only. Portion 12 can also have other geometric shapes, including but not limited to rectangular, triangular, polygonal, and the like within the scope of the present disclosure. According to several embodiments, material for clip 10 can be a polymeric material such as a polyamide material. The polymeric material selected can be molded such as by injection molding into the shape shown in FIG. 1. Clip 10 although described in several embodiments as a molded polymeric part can in further embodiments be made from polymeric coated metal or a polymeric material impregnated with a metal, formed such as by powder forming, potting, or casting, or from a combination of polymeric materials which are co-molded to form a homogenous clip 10. The material and forming method for clips 10 do not limit the scope of the present disclosure.

Clips 10 of the present disclosure offer several advantages. The opposed flanges 18, 20 which are separated by gap 32 have convexly curved surfaces 22, 24 which promote frictional engagement with the inner walls of similarly curved arms 42, 44 of frame member 40 when flanges 18, 20 are rotated following a sliding insertion of clip 10. To further assist the frictional contact of clips 10, contact of convexly curved surfaces 22, 24 with inner walls of arms 42, 44 also can promote contact of surfaces 26, 28 with cavity 46 facing surfaces of outwardly directed portions 48a, 50a of opposed walls 48, 50. Angle α created between first and second legs 14, 16 promotes an elastic biasing force when first and second legs 14, 16 are pressed toward each other during insertion of clip 10 into frame member 40. The biasing force also helps retain clips 10 within frame member 40. The neck 34 separating semispherical portion 12 from first and second legs 14, 16 provides a rotational sliding contact surface with the free ends of arms 42, 44 to promote rotation of clip 10 during installation. Because clips 10 are rotated to frictionally engage frame members 40, clips 10 are also releasable by rotation to the original orientation, which allows clips 10 to be moved to alternate locations, or removed entirely from frame members 40.
