Shear and water resistant felt pad
A protector pad for use with a piece of furniture with legs, and having a flat body with a lower pad face to slide against surfaces and an upper pad face to be fixed to the leg. The flat body includes a base and a sole. The base includes a fabric with a superior face forming the upper pad face and an inferior face having first means for assembly. The sole includes a lower layer whose inferior face defines the lower pad face, and an upper layer with a superior face having second means for assembly to assemble the sole to the base along an interface plane. The first means includes a plurality of grabbing member hooks each providing an equal shear resistance in all directions parallel to the interface plane. Typically, a reinforced material in a central layer includes a felt impregnated by a hardened latex material.
1 . A protector pad for use with a piece of furniture with legs, said pad comprising a generally flat body ( 30 ) with two opposite pad faces:
a lower pad face ( 22 ) which is soft, destined to slide against delicate surfaces without scratching them and,
an upper pad face ( 26 ) destined to be fixed to the bottom of said leg ( 28 ) of said piece of furniture, said flat body ( 30 ) being constituted of two pieces, a base ( 32 ) and a sole ( 34 ); said base comprising a fabric ( 38 ) with a superior face forming said upper pad face and an inferior face ( 36 ) comprising first means for assembly; said sole comprising a lower layer ( 46 ) whose inferior face defines said lower pad face ( 22 ), and an upper layer ( 42 ) with a superior face ( 43 ) comprising second means for assembly to assemble said sole ( 34 ) to said base ( 32 ) along an interface plane, wherein said first means for assembly comprise a plurality of grabbing member hooks ( 36 ), each member hook providing a substantially equal shear resistance in all directions generally parallel to said interface plane.
2 . The protector pad of claim 1 wherein a central layer ( 48 ) of said sole, located between said lower ( 46 ) and upper ( 42 ) layers, comprises a reinforced material.
3 . The protector pad of claim 2 wherein said reinforced material in said central layer comprises a felt impregnated by a hardened material coming from a group comprising a latex base.
4 . The protector pad of claim 1 wherein said member hooks ( 36 ) includes mushroom type hooks.
5 . The protector pad of claim 4 wherein said mushroom type hooks have a unit density of a number of about 110 heads/cm 2 and a height not exceeding about 1.45 mm.
6 . The protector pad of claim 1 wherein said shear resistance has a shear strength of about 60 N/cm 2 .
7 . The protector pad of claim 4 wherein said member hooks ( 36 ) have a weight density of at least about 350 g/m 2 and have a breaking strength of about 350 N/cm.
8 . The protector pad of claim 1 wherein said second means of assembly ( 42 ) comprise fibers forming arches ( 44 ), said upper layer ( 42 ) of said sole ( 34 ) comprises a felt the fibers thereof forming said arches, said felt comprises materials from a group comprising polyester and natural fibers, said superior layer ( 42 ) and inferior ( 46 ) layers are made of felt material, said felt material consists either of polyester or natural fibers.
9 . The protector pad of claim 2 wherein said reinforced material is hardened felt comprising injected latex.
