Fastening or mounting apparatus
A fastening or mounting apparatus for releasably joining two objects is disclosed. The apparatus uses a cam portion opposite a hook portion in a structure of one of the objects to engage with flanges, protrusions or ends of the other object. In the case of flanges, one of the flanges deforms a resilient element in the hook portion during insertion, and the other flange snaps into the detent of the cam portion upon application of force. The apparatus may be adaptable from small scale applications to large-scale heavy duty applications.
1. A fastening apparatus, comprising:
a plate having a top side, a bottom side, and a first end opposite a second end, the first end having a first lip extending downwardly from the bottom side of the plate, the first lip at least partially defining a channel with a projection from the lip, the channel being positioned along the length of the first end, the channel having a natural or synthetic polymeric reversibly compressible strip or cord in the channel, the channel having an aperture along the length of the channel, the aperture facing a second lip on a second end, the second lip extending downwardly from the bottom side of the plate, the second lip having a detent portion and a portion that is shaped substantially semicircular and is convex relative to the first lip; wherein the fastening device is removably securable to an object via compression of the strip or cord in the channel with the object and snap action to secure the object between the first and second lip.
2. A fastening apparatus, comprising:
a hook portion comprising a lip at least partially defining a cavity together with a projection extending from the lip, with a reversibly compressible strip or cord comprising a natural or synthetic polymer, the strip or cord being within the cavity, the strip or cord being at least partially exposed through an opening in the cavity; and
a cam portion opposite the hook portion, the cam portion having a detent and a convex portion;
the hook portion and the cam portion being directly or indirectly structurally connected and configured to be releasably fastenable by resiliency of strip or cord following compression.
3. The fastening apparatus of claim 2 wherein the strip or cord has a Type A scale Durometer of between 40 and 90.
4. The fastening apparatus of claim 2 wherein the strip or cord comprises at least one of a natural rubber, a synethtic rubber and a polymer.
5. The fastening apparatus of claim 2 wherein the detent is concave.
6. The fastening apparatus of claim 2 wherein the detent is flat.
7. The fastening apparatus of claim 2 the convex portion is substantially semicircular.
8. The fastening apparatus of claim 2 wherein the cam portion and the hook portion are in one of a battery housing or a battery tray.
9. The fastening apparatus of claim 8 further including an electrical connection for electrical communication with a battery.
10. The fastening apparatus of claim 2 wherein the cam portion and the hook portion are in a structure for supporting a solar panel.
11. The fastening apparatus of claim 10 further including an electrical connection for electrical communication with the solar panel.
12. The fastening apparatus of claim 2 wherein the hook portion and the cam portion are positioned opposite one another.
13. The fastening apparatus of claim 2 wherein the hook portion and the cam portion are positioned to face one another.
14. A fastening system, comprising:
a terminal hook portion comprising a lip at least partially defining a cavity with a reversibly compressible strip or cord comprising a natural or synthetic polymer therein, the reversibly compressible strip or cord being partially exposed through an opening in the cavity;
a terminal cam portion opposite the hook portion, the cam portion having a detent and a convex portion; and
at least one center connector between the terminal hook portion and the terminal cam portion, the center connector having back-to-back hook and cam portions such that each hook portion in the fastening system corresponds with and faces one cam portion inclusive of the terminal hook portion and the terminal cam portion;
wherein each detent is opposite the opening of its corresponding hook portion and each pair of hook and corresponding cam portion is releasably fastenable to an object having a first end insertable into the opening by compressing the reversibly compressible strip or cord and a second end snappable into the corresponding detent.
15. The fastening system of claim 14 adapted to receive solar photovoltaic panels between each pair of hook and corresponding cam portions.
16. The fastening system of claim 15 further comprising at least one electrical connection between the fastening system and at least one of the solar photovoltaic panels.
