Abstract: A brake-equipped swivel caster including a tired wheel rotatably fitted to a support leg comprises a movable pin allowed to move up and down inside the vertical axial member and normally retained by an elastic member in its uppermost position, left and right brake arms in a pair swingably fitted to the support leg and normally retained by elastic members such that their lower ends are a specified distance apart from the lateral wheel surfaces of the tired wheel, and an operation mechanism arranged over the movable pin. When the operation mechanism pushes down the movable pin a specified distance, a tapered lower end portion of the movable pin causes the brake arms to turn by pushing outward on the upper ends of the brake arms, so that the lower ends of the brake arms are pressed against the lateral wheel surfaces of the tired wheel.

Abstract: A brake-equipped swivel caster comprises a movable pin allowed to move up and down and normally retained in its uppermost position by an elastic member, and a bifurcated brake member including two downward-extending brake pieces, arranged with its top adjacent to the lower end of the movable pin and rotatably suspended by a horizontal shaft fitted to a tired-wheel support leg at a position off the axis of the movable pin. The brake member is subjected to the force of an elastic member tending to cause the brake member to turn in a direction away from the opposite lateral rim edges of a tired wheel, and is thereby retained in a non-braking condition. When the movable pin pushed down a specified distance pushes on the top of the brake member, the brake member turns so that the two brake pieces are pressed against the opposite lateral rim edges.

Abstract: The present invention provides a internal pipe joints suitable for connection when pipes used under light-load conditions, or to be more concrete, plastic coated steel pipes having an external diameter ranging from about 28 mm to about 45 mm, which are produced by coating the outer surfaces of thin steel pipes with synthetic resin in a thin layer, are assembled into a planar or three-dimensional pipe structure, and more specifically, relates to pipe joints that have high strength in pipe connection and is excellent in design for having a simple appearance design in the position connecting the pipes.

Abstract: The present invention provides a pipe joint which gives a sufficient resistance against pulling tension without increasing contact length with pipes and which allows an attractive appearance for the coupled pipes.
