Abstract
The present invention relates a simple, inexpensive clamp comprised of a flexible "C"-shaped, fixed-diameter clamping means, a rigid support member, and a "C"-shaped anchoring means whose overall design and construction allows the user to fasten, secure, and release objects quickly and easily with a minimum level of dexterity.
Claims12
An easy to fasten and release clamp comprising:
- (i) one or more resilient fixed-diameter plastic clamping means having a curved circular member with an inner and an outer surface an an open gap such that said clamping means is "C"-shaped when viewed from the top, said curved member having a uniform thickness which allows said curved member to expand and contract in response to lateral pressure directed at said open gap when an object is forced against said open gap, and wherein said inner surface bears a continuous corrugated pattern of vertical cog-like teeth;
- and
- (ii) a rigid cylindrical plastic extension rod having a forward and a rear end, said forward end being joined to said outer surface of said curved member substantially opposite said open gap, and wherein said forward end is tapered and narrowed along vertical planes to match the thickness of said curved member.
An easy to fasten and release clamp comprising:
- (i) one or more resilient fixed-diameter plastic clamping means having a curved circular member with an inner and an outer surface and an open gap such that said clamping means is "C"-shaped when viewed from the top, said clamping means further having a tapered shape when viewed from the side, and said curved member having a uniform thickness with allows said curved member to expand and contract in response to lateral pressure directed at said open gap when an object is forced against said open gap, and wherein said inner surface bears a continuous corrugated pattern of vertical cog-like teeth and an extra inner groove cut along a horizontal plane;
- and
- (ii) a rigid cylindrical plastic extension rod having a forward and a rear end, said curved member substantially opposite said open gap, and wherein said forward end is tapered and narrowed along vertical planes to match the thickness of said curved member.
