Patent Application
20230090956
The present application relates to a trailer, and more particularly to a floor dampening unit within a trailer to reduce vibrational effects.
Trailers are commonly used by the public for personal, commercial, and industrial uses. There are many types of trailers and various ways to connect them to a pulling vehicle. A trailer is designed to generally carry a load behind a pulling vehicle. Trailers have a flat surface in which to load objects. The weight of these objects are supported by the trailer frame and are “cushioned” by mechanical leaf springs between the floor of the trailer and the axle. Usually shocks are not include on trailers. It is relatively known that the ride quality in the back of a trailer can be fairly rough and uncomfortable. While typically this does not matter so much, especially in instances when the load carried is an object, such ride quality may matter when the load carried is alive.
Trailers are commonly used to carry live animals. The animals are oriented and packed into the trailers in a manner that is most efficient for the operator. Usually the goal is to place them in the trailer in the least amount of space necessary to enable one to carry more animals. The animals, as seen with large livestock especially, are typically required to stand while in the trailer. Not a lot of room is generally left for animals to move about and lie down. An animal that lies down can cause injury to itself by being stepped on or can hurt other animals.
The level of fatigue that an animal is exposed to in a trailer is real. To reduce fatigue, efforts have been made to coat the floor of the trailer with mats to cushion the feet of the animal. While providing some assistance, the animal is still left to absorb a great amount of vibration and forces from ill tuned trailer suspensions. Trailer suspensions provide minimal comfort for vibrations transmitted to the livestock.
Although strides have been made, shortcomings remain. It is desired that an assembly be provided that is configured to minimize and isolate vibrations and forces between the trailer and the animal being carried.
It is an object of the present application to provide an air ride floor assembly that is located in a trailer to isolate floor vibrations and forces between the trailer and any cargo being carried, whether living cargo or inanimate cargo. It is desired that the floor assembly be incorporated within the trailer as a whole unit or is provided alternatively as a separate retrofit option for existing trailers.
It is a further object of the present application that a floor is suspended above the frame of the trailer via pneumatic air pressure via one or more airbags. The assembly may also include one or more shocks to dampen any movements of the airbags.
Another object of the present application is to permit the airbags to be collectively regulated through one or more compressors and a control unit. The pressure in the airbags may be adjusted by adding or removing air. A user is able to engage one or more controls to activate a compressor. Each airbag may be isolated for individual control and/or all airbags may be regulated collectively.
Wherein the floor assembly is a retrofit unit, the floor may be added and removed to a trailer. Additionally, the floor assembly is ideally suited to cover the entire floor, however, some uses may prefer to restrict the size so as to be smaller than the floor size of the trailer.
Ultimately the invention may take many embodiments. In these ways, the present invention overcomes the disadvantages inherent in the prior art. The more important features have thus been outlined in order that the more detailed description that follows may be better understood and to ensure that the present contribution to the art is appreciated. Additional features will be described hereinafter and will form the subject matter of the claims that follow.

Controller 103 is in electrical communication with compressor 105 and is configured to run or operate compressor 105. Controller 103 may turn compressor on/off and regulate the discharge of air pressure through one or more lines 111. The lines run from compressor 105 to the one or more airbags 107. As described, assembly 101 is operable with pneumatic air pressure, however, other forms of liquids are permitted and their adoption and use may be dependent upon design criteria. Controller 103 and compressor 105 are coupled to a portion of the trailer 99 and may be powered by an external battery or through the pulling vehicle itself. Compressor 105 and controller 103 may be removed from trailer 99.
Airbag 107 is coupled to a lower portion of floor 109. As seen in
The purpose of airbags 107 is to minimize the vibrational effects and load forces exerted upon and by trailer 99 and floor 109. This is extremely useful when the carried load is livestock. This assists in drastically decreasing fatigue on the animals and can assist in preventing injuries. As shown a plurality of airbags 107 are used. The air pressure in each airbag 107 may be regulated independent of the other airbags or in combination with the other airbags as a collective whole. One or more lines 111 may be used to accomplish this feature.
Assembly 101 may further include one or more guide members 115 configured to partially restrict the movement of floor 109 on the airbags 107. Guide members 115 are coupled to a lower portion of the floor 109 and may also be coupled to an upper portion of base unit 113 when used. As airbags 107 are cushions of air, a tendency may be realized wherein floor 109 may want to move laterally. Floor 109 is configured to move independent of trailer 99 and its side walls. Floor 109 is not required to be in contact with any walls of trailer 99. In order to alleviate or stop lateral movements of floor 109 which may result in undesired contact with trailer 99, guide members 115 are included. Guide members 115 are configured to permit vertical translation of floor 109 but not lateral translation. Guide members 115 include telescoping cylinders in this embodiment to facilitate this function. Other embodiments are possible. It should be stated that guide members 115 may include a dampener configured to slow or stop bouncing effects from airbags 107. In this way, guide members 115 may be a shock absorber.

As seen in particular in
During operation, a user may operate controller 103 to regulate performance of compressor 105 which in turn adjusts the pressure in airbags 107. Controller 103 may also be configured to include sensors 123 to read and therefore display air pressure status for each airbag or collectively. The floor assembly may be removed or inserted into any appropriately sized trailer. The air pressure may be adjusted once the load is determined. Adjusting the air pressure differently between the airbags may be needed depending on the load distribution on floor 109.
It should be noted that assembly 101 may include a barrier 125 at a rear portion of the assembly that is configured to block access under floor 109. Barrier 125 may be attached to base unit 113 or floor 97 depending on configuration.
The particular embodiments disclosed above are illustrative only, as the application may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application. Accordingly, the protection sought herein is as set forth in the description. It is apparent that an application with significant advantages has been described and illustrated. Although the present application is shown in a limited number of forms, it is not limited to just these forms, but is amenable to various changes and modifications without departing from the spirit thereof.
