Device for attaching sheets to a waterbed

A bed sheet attachment device for use in combination with a waterbed of the type having a frame including upstanding side walls surrounding at least a portion of a fluid-holding mattress, the bed sheet attachment device comprising:

• (a) a plate-like member having an upper end and a lower end;
• (b) means for defining a stud-holding opening extending through said plate-like member;
• (c) means defining a transverse slot located in said plate-like member between said stud-holding opening and said lower end;
• (d) a stud having a pair of opposite ends and a relatively slender neck interconnecting said opposite ends;
• (e) said stud-holding opening including a slot portion having a width, adjacent said upper end of said plate-like member, which is great enough to receive said neck of said stud and at least one layer of cloth wrapped around said neck, but said width being small enough to prevent said ends of said stud from passing therethrough;
• and
• (f) elastic connecting means attached to said lower end, for connecting said first member to a portion of the frame of a waterbed, said elastic connecting means including an elastic tape having a pair of ends, said tape extending through said transverse slot and said ends being fastened together parallel with one another by a grommet defining a central opening for receiving a fastener therethrough.

A waterbed, comprising:

• (a) a mattress-supporting frame, including respective generally vertical head end, foot end, and opposite side wall members defining a plurality of corners of said frame;
• (b) a fluid-holding mattress supported on said frame with said wall members thereof extending upwardly alongside at least a part of said mattress;
• and
• (c) a plurality of bed sheet attachment devices each including
• (i) a plate-like member of plastic material, having an upper end and a lower end;
• (ii) a stud having a head, a base, and a relatively slender neck interconnecting said head and said base;
• (iii) means for defining an opening through said plate-like member, said opening including a tapered slot portion large enough to receive said neck of said stud but too small for either said head or said base to pass therethrough, said opening further including an enlarged portion which is located proximate said lower end and which is large enough to permit passage of at least said head therethrough;
• (iv) means defining a transverse slot passing through said plate-like member, located between said lower end of said plate-like member and said enlarged portion of said opening;
• (v) elastically extendable connecting means including an elastic strap having first and second ends, said elastic strap being disposed through said transverse slot and said first and second ends of said strap being permanently held together parallel with one another by a fastener associated with said first and second ends of said elastic strap so as to form a loop therein;
• and
• (vi) attachment means for holding said fastener to said frame proximate one of said corners, said fastener defining a central opening for receiving said attachment means.
