Definitions
- the present invention relates generally to hose clamps, and more particularly to clamps used to interconnect and seal components of heating, ventilation and air conditioning (HVAC) systems connected by hoses.
- HVAC heating, ventilation and air conditioning
- An embodiment contemplates a hose clamp for securing a hose to a component, the clamp including 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.
- the elastic energy of the spring material from which the hose clamp is made is employed in the axial direction, i.e., along the hose centerline, producing axially positioned locking features on the clamp, whereas a conventional hose clamp requires radially positioned locking features.
- the axial locking features are produced within the thickness of the clamp material; therefore, the external profile of the clamp is only slightly greater than the outside diameter of the clamp.
- the invention employs the elastic characteristics of the clamp to accomplish the clamping function and to lock the clamp in its opened condition in preparation to be used or in closed condition while being used.
- An advantage of an embodiment is reduction of the space occupied by a hose clamp before and after its installation and use.
- the clamp has lower weight and cost and requires a shorter installation or removal time than a conventional hose clamp.

Abstract
Description
- The present invention relates generally to hose clamps, and more particularly to clamps used to interconnect and seal components of heating, ventilation and air conditioning (HVAC) systems connected by hoses.
- Conventional hose clamps used currently in HVAC systems in the automotive industry require access space around the clamps due to features of the clamp required to close and open the clamp. For this reason, packaging of the components around hose attachments is difficult because of the extra space required for the clamp and for space reserved for handling during assembly and service operations.
- Additional space around the clamps is required to provide adequate clearance from components that can be damaged due to contact with the clamp, such as wiring harnesses, hoses, plastic parts, etc. Such components can be adversely affected by extremely aggressive clamping activity and because the clamps are made of spring steel.
- Directly related to the complexity of conventional spring-loaded hose clamp designs, the weight and cost of the clamps are high, and the cost of tools for installing and removing them is high.
- A need exists in the industry for a hose clamp that requires less space, is easier to manufacture, has fewer parts, requires fewer tools to install and remove, and requires less time to install and remove than a conventional hose clamp.
- An embodiment contemplates a hose clamp for securing a hose to a component, the clamp including 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.
- The elastic energy of the spring material from which the hose clamp is made is employed in the axial direction, i.e., along the hose centerline, producing axially positioned locking features on the clamp, whereas a conventional hose clamp requires radially positioned locking features. The axial locking features are produced within the thickness of the clamp material; therefore, the external profile of the clamp is only slightly greater than the outside diameter of the clamp.
- The invention employs the elastic characteristics of the clamp to accomplish the clamping function and to lock the clamp in its opened condition in preparation to be used or in closed condition while being used.
- An advantage of an embodiment is reduction of the space occupied by a hose clamp before and after its installation and use. The clamp has lower weight and cost and requires a shorter installation or removal time than a conventional hose clamp.
