Embodiment Construction

[0022] first reference figure 1 , the first hose clamp 10 is formed from a resilient material, preferably steel, as a round, open ring of uniform thickness. figure 1 The clip 10 is shown in its closed state. figure 2 The clip 10 is shown in its open state, wherein the clip creates and maintains a resilient preload tending to return the clip to its closed state.

[0023] The clip 10 includes first and second mutually parallel strips 12 , 14 extending around the circumference of the clip, each strip extending axially along a portion of the width of the clip 10 . The first transition surface 16 leads to the strip 12 and its open end 18 . The second transition surface 20 leads to the band 14 and its open end 22 facing and spaced from the surface 16 . Similarly, end 18 faces and is spaced from transition surface 20 .

[0024] The band 12 is formed with recesses 24 , 26 , 28 circumferentially spaced from each other. The strap 14 is formed with a protrusion 30 capable of engagi...

Abstract

A hose clamp for securing a hose to a component includes a first band of uniform thickness that extends angularly about an axis and includes an engagement surface, and a second band having the uniform thickness and formed in one piece with the first band, extending angularly about the axis, offset axially from the first band, and including a latch surface engageable with the engagement surface, the clamp having an open state in which the first band and the second band are elastically urged angularly about the axis toward contact with the hose, said engagement maintaining an elastically resilient load between the first band and the second band.

Description

technical field [0001] The present invention relates generally to hose clamps, and more particularly to clamps for interconnecting and sealing components of heating, ventilation and air conditioning (HVAC) systems connected by hoses. Background technique [0002] Conventional hose clamps currently used in automated industrial HVAC systems require access space around the clamp because of the clamp features required to close and open the clamp. For this reason, packaging the components around the hose attachment is difficult as additional space is required for the clips and space reserved for handling during assembly and maintenance. [0003] Additional space around the clip is required to provide sufficient clearance from components that could be damaged due to contact with the clip (eg wiring harnesses, hoses, plastic parts, etc.). Such components can be adversely affected by extremely aggressive clamping actions because the clips are made of spring steel. [0004] Directl...
