Patent Application
20080179881
The present invention relates generally to air distributions products, and more specifically to a flexible, compact connector used, for example, to connect a clothes dryer vent with an exhaust vent.
Clothes dryers and other similar appliances force heated air out and away from the dryer or appliance. Homes and commercial laundry facilities have an exhaust vent to the outside or to other duct work within the building in order to get the hot air away from the dryer or appliance. Often the dryer vent and the exhaust vent are not in alignment, or the dryer vent is spaced apart from the exhaust vent. Therefore, in order to connect the dryer vent and the exhaust vent it is common to use a connector of some sort. Typically, the connector is coupled to the dryer vent and to the exhaust vent for proper ventilation of the hot air. Connectors are typically made of metal, plastic, or fabric, or a combination thereof, and have a variety of designs.
Several drawbacks or limitations exist with prior designs. Plastic and fabric materials often tear or become deformed to a degree that makes the dryer inefficient. Such materials are often too flexible and prone to fatigue from exposure to heat or from being moved or damaged by the components being connected. Moreover, while these material can be adjustable, they are poor in maintaining their shape after adjustment which leads to substantial difficulty in operation and maintenance. Metals can be too rigid to make the correct connection and alignment possible, and are difficult to maneuver and adjust. It would be beneficial to provide a connector that maintains its shape but is still flexible.
Proper connection between the dryer vent and the exhaust vent is important for proper ventilation and efficiency of the dryer. Connecting the dryer vent and the exhaust vent can be difficult because of the available space to work in to make this connection. Often the dryer is between the washer and the wall and is in a small closet or other restricted area. Due to space constraints it would be beneficial to provide a connector that was able to have a variety of angles and lengths.
The present invention comprises a compact, semi-rigid, adjustable connector. A principal object of the present invention is to provide a multi-angle connector to connect a dryer vent and an exhaust vent that maintains the basic tubular shape while allowing for a variety of angles in order to make a proper connection between the dryer vent and the exhaust vent. The multi-angle connector is flexible 360 degrees to make an elbow type connection behind the dryer. The multi-angle connector comprises a tubular sleeve with an opening at each end of the sleeve. The sleeve has numerous ridges in order for the sleeve to bend in a variety of angles. Interlocking crimped lips are spaced apart (e.g., approximately every 10 ridges) to assist in achieving the desired adjustability of the connector. The connector provides for the proper alignment of the dryer vent and the exhaust vent and can be twisted and angled in order to fit any space and vent positioning. Also, the connector is made of a durable, semi-rigid flexible material in order to maintain the tubular shape of the sleeve.
The foregoing and other objects are intended to be illustrative of the invention and are not meant in a limiting sense. Many possible embodiments of the invention may be made and will be readily evident upon a study of the following specification and accompanying drawings comprising a part thereof. Various features and subcombinations of invention may be employed without reference to other features and subcombinations. Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, an embodiment of this invention and various features thereof.
A preferred embodiment of the invention, illustrative of the best mode in which the applicant has contemplated applying the principles, is set forth in the following description and is shown in the drawings and is particularly and distinctly pointed out and set forth in the appended claims. The drawings submitted are informal and will be replaced with more formal drawings in the future.
As required, a detailed embodiment of the present inventions is disclosed herein; however, it is to be understood that the disclosed embodiment is merely exemplary of the principles of the invention, which may be embodied in various forms.
