Secure mounting arrangement for U-shaped bolts and other device
View Patent ↗A U-shaped bolt including a closed end and two legs at an open end is self-retaining on a first object. The U-shaped bolt includes projections forming an opening to the closed end adapted to be smaller than the width of the first object. The projections retain the U-shaped bolts on the first object. The U-shaped bolt is used in conjunction with a space heater having a plurality of heating elements connected by channels. The U-shaped bolt is retained on the channels to warrant proper assembly of the space heater.
1. A space heater comprising:
a plurality of elongated heat radiating elements;
a plurality of channels connecting the elongate heat radiating elements; and
at least one U-shaped bolt receiving one of the channels, each U-shaped bolt comprising:
a closed end receiving the channel, the closed end having an inner dimension substantially equal to a dimension of the channel;
an open end with two legs; and
at least one projection disposed between the closed end and a tip of one leg, the projection defining an opening having a dimension which is smaller than the dimension of the channel and retains the U-shaped bolt on the channel.
2. The space heater of claim 1 wherein the U-shaped bolt includes projections between the closed end and a tip of each leg.
3. The space heater of claim 1 wherein the bolt is formed of an elastic material.
4. The space heater of claim 1 wherein the elastic material is a steel.
5. The space heater of claim 1 wherein a portion of the two legs are parallel.
6. The space heater of claim 1 wherein the end of at least one leg is threaded.
7. The space heater of claim 1 wherein the end of at least one leg includes a foot adapted to secure an object on the bolt.
8. The space heater of claim 1 wherein the end of one leg is threaded and the end of the other leg includes a foot adapted to secure an object on the bolt.
9. The space heater of claim 1 , further including wheels mounted to a plate, wherein the U-shaped bolt secures the plate to the heat radiating elements.
10. The space heater of claim 9 wherein the legs of the U-shaped bolt pass through holes in the plate.
11. A space heater comprising:
a plurality of elongated heat radiating elements;
a plurality of channels connecting the elongate heat radiating elements;
at least one plate including wheels attached thereto; and
at least one U-shaped bolt, each U-shaped bolt comprising:
a closed end receiving one of the plurality of channels, the closed end having an inner dimension substantially equal to a dimension of the channel;
an open end with two legs, the legs passing through at least one hole in the plate, the first leg being threaded and including a nut thereon and the second leg including a foot, the nut and foot retaining the plate on the U-shaped bolt; and
at least one projection disposed between the closed end and a tip of one leg, the projection defining an opening having a dimension which is smaller than the dimension of the channel and retains the U-shaped bolt on the channel.
