Abstract
A burnable coil holder such as a mosquito coil holder has a base member with a plurality of non-metallic support peaks and a higher central metal support spade. The spade supports the burnable coil from a single point under normal circumstances. The non-metallic support peaks provide support if the coil sags during use. The support peaks are positioned in a cross or spiral array around the spade. The spade has teeth to grip the coil, a shoulder to support the coil, and spaced legs to permit easy insertion of the spade into the base member.
Claims16
A burnable coil holder assembly, comprising a base member having extending upward therefrom
- a. a spade suitable to support a burnable coil, and
- b. an array of non-metallic peaks positioned around the spade that are suitable to support the burnable coil if the coil sags adjacent them;
- wherein the spade extends higher than the array of peaks;
- and
- wherein the spade has a tapered upper portion adjacent and above a plurality of outer side teeth, the teeth being along sides of the spade adjacent and below the tapered upper portion.
An assembly of a plurality of support members for supporting a burnable coil, the assembly having been formed from a single strip of material, the assembly comprising:
- a first support member for supporting a burnable coil having at a head end a spade with a tapered portion, a radially extending tooth along a side of the spade, a support shoulder adjacent the tooth but on an opposite side of the tooth from the head end, and two legs extending axially away from the shoulder and away from the head end;
- and
- a second support member having at a head end of the second support member a spade with a tapered portion, a radially extending tooth along a side of the spade of the second support member, a support shoulder adjacent the tooth of the second support member but on an opposite side of the tooth of the second support member from the head end of the second support member, and two legs extending axially away from the shoulder and head end of the second support member;
- wherein at least one leg of said two legs of the first support member is interfit with the tooth of the second support member.
A method of supporting a burnable coil on a holder, the holder having a base member having extending upward therefrom a spade suitable to support a burnable coil, and an array of non-metallic peaks positioned around the spade that are suitable to support the burnable coil if the coil sags adjacent them, the spade extending higher than the array of peaks, the method comprising positioning a burnable coil on the spade, above the array of peaks.
