[0012] To further clarify various aspects of some example embodiments of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It is appreciated that these drawings depict only illustrated embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:

[0013] FIG. 1 illustrates an example of a hose kit; and

[0014] FIG. 2 illustrates an example of a hose kit attached to a vehicle.

DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS

[0015] Reference will now be made to the figures wherein like structures will be provided with like reference designations. It is understood that the figures are diagrammatic and schematic representations of some embodiments of the invention, and are not limiting of the present invention, nor are they necessarily drawn to scale.

[0016] FIG. 1 illustrates an example of a hose kit 100. The hose kit 100 can allow a user to simultaneously change the tire pressure of multiple tires. I.e., the hose kit 100 can allow a user to inflate or deflate more than one tire at the same time. In particular, inflating or deflating multiple tires simultaneously is not simply a matter of hooking an air hose to each tire. Doing so leads to a number of problems which will be discussed herein.

[0017] FIG. 1 shows that the hose kit 100 can include a manifold 102. The manifold 102 distributes air in multiple directions. For example, the manifold 102 can receive compressed air and split the air flow into two or more outputs. I.e., the manifold 102 connect a single input with multiple outputs. Likewise, the manifold 102 can take multiple air flows and combine them into a single air flow, which is being used in a deflation operation. I.e., the manifold 102 can connect multiple outputs with a single input. One of skill in the art will appreciate that the terms input and output are not necessarily defined by air flow. For example, if the air compressor is being used to deflate tires, then airflow is from multiple outputs in the manifold 102 to a single input of the manifold 102. During an inflation operation, the air flow is from the single input of the manifold 102 to the multiple outputs of the manifold 102.

[0018] FIG. 1 also shows that the hose kit 100 can include a gauge 104. For example, the gauge 104 can be attached to the hose kit 100 at the manifold 102. I.e., the gauge 104 can show a measurement of air pressure at the manifold 102, which equates to the air pressure at all points in the hose kit 100 (if all connection points along the hose kit 100 are open). The gauge 104 allows the user to determine the current pressure in the multi-tire inflation/deflation system 100 and by extension any connected tires. This allows the user to determine the current state of all tires simultaneously. The gauge 104 can be an analog or digital gauge. The gauge 104 is not as accurate when the air compressor 102 is actively moving air, because air currents cause noise in the gauge. However, it can be used to approximate the pressure and will be accurate when the air compressor 102 is not actively moving air.

[0019] FIG. 1 further shows that the hose kit 100 can include one or more output air hoses 106. The output air hoses 106 are configured to attach to the manifold 102. This allows a user to equalize air pressure in multiple connected tires. I.e., the output air hoses 106 create an indirect physical connection between the manifold 102 and the connected tires. The output air hoses 106 can be attached to the manifold directly or via a releasable connection, such as an air chuck. As used in the specification and the claims, the phrase configured to denotes an actual state of configuration that fundamentally ties recited elements to the physical characteristics of the recited structure. That is, the phrase configured to denotes that the element is structurally capable of performing the cited element but need not necessarily be doing so at any given time. Thus, the phrase configured to reaches well beyond merely describing functional language or intended use since the phrase actively recites an actual state of configuration.

[0020] FIG. 1 additionally shows that the hose kit 100 can include tee fittings 108. The tee fittings 106 are connected to each of the output air hoses 106. The tee fittings 106 allow one input air hose 122 to be connected to multiple output air hoses 106. I.e., the tee fittings 108 connect three connected air hoses, one of which will be the output air hose 106. One of skill in the art will appreciate during active air movement that the tee fittings 108 reduces the amount of air flow in the output hoses (since the output hoses have a bigger combined cross-sectional area than the input cross-sectional area) but without active air flow, pressure will equalize. Therefore, if an air compressor is connected it needs to be capable of creating enough flow to inflate all connected tires via all connected output air hoses 106.

[0021] FIG. 1 moreover shows that the hose kit 100 can include a tire whip 110. The tire whip 110 can be connected to a nearby tire. I.e., the tire whip 110 is intended to convey air between a tire and a tee fitting 108. Tire whips 110 provide a number of benefits relative to attaching an air chuck directly to the tee fitting 108. First, the tire whip 110 gives flexibility to connect to tires. Second, for some tires the air stem is not on the exterior of the tire or is otherwise protected and a tire whip 110 allows for a connection to these tires. I.e., the tire whip 110 makes connection to a tire easier in situations where there is not a straight shot to an air stem. Finally, some air stems point toward the center of the tire. This is reachable with a tire whip 110 but not with an air chuck attached to a tee fitting 108.

[0022] FIG. 1 also shows that the hose kit 100 can include a tire hose 112. The tire hose 112 allows for connection to one or more additional tires after splitting of the air flow by tee fitting 108. I.e., the tire hose 112 is similar to a tire whip 110 in that it is a hose connected to a tee fitting 108 which can connect to a tire.

[0023] One of skill in the art will appreciate that instead a second output air hose 106 can be connected to the tee fitting 108. This allows a user to connect multiple tires. For example, if the user needs to connect to a vehicle with six tires, then one output air hose 106 is connected on one end to a manifold 102 and a tee fitting 108 on the other end. The tee fitting 108 can be connected to a tire whip 110 and a second output air hose 106, which is connected to a second tee fitting 108. The second tee fitting 108 has a second tire whip 110 connected and a tire hose 112. The two tire whips 110 and the tire hose 112 are each connected to one tire. The layout is similar on the other side of the manifold 102.

[0024] FIG. 1 further shows that the hose kit 100 can include a locking air chuck 114. The locking air chuck 114 attaches to the stem valve of a tire and then locks into place. The locking air chuck 114 is placed as far as possible on the stem valve of a tire with collar 128 pulled all the way back. The user then slides the collar 128 forward while holding pressure on the valve stem. Unless placed on a stem valve, the locking air chuck 114 defaults to a closed position to prevent air leakage. Thus, if three locking air chucks 114 are placed on tires and a fourth locking air chuck 114 is left free, air will only flow through the three output air hoses 106 which are connected to tires via a locking air chuck 114. An example of a locking air chuck is disclosed in Ser. No. 18/886,838 filed on Sep. 16, 2024 and entitled LOCKING AIR CHUCK which application is incorporated herein by reference in its entirety.

[0025] FIG. 2 illustrates an example of a hose kit 100 attached to a vehicle 202. The vehicle 202 has four tires 204 but can include any number of tires and the hose kit 100 can be used to inflate a single tire if needed (although this is not optimal). The tires 204 of the vehicle become equalized with the same pressure when all attached via the hose kit 100.

[0026] When first placed on the tires 204 the hose kit 100 equalizes all pressures within the tires 204, since the output air hoses 106 have an open connection to all tires 204 via the locking air chucks 114. I.e., all tires 204, tire whips 110 and tire hose 112 become a single system with equal pressure throughout. The pressure can be determined by the user via gauge 104. The user can then add air or remove air depending on what is needed to achieve the desired final pressure.

[0027] The materials and dimensions of the air hoses are critical for correct operation (as used herein air hoses includes any hose, including output air hoses 106, tire whips 110, and tire hoses 112). Air hoses must be long enough to reach the tires but short enough that they don't make it difficult to maintain a desired pressure. Problems discovered during creation and use of the air hoses in off roading conditions include: 1) the hoses are exposed to UV from sunlight, causing some materials to crack; 2) hoses can have memory and when wound for long periods of time can be difficult to return to a straight configuration; and 3) during cold conditions (either during use or during storage) can crack or break. To solve these problems, the air hoses are made of 3-layer rubberized polyvinyl chloride (PVC) material. Rubberized PVC is freeze resistant, does not hold memory, so it lays flat for each use, and is UV resistant, which prevents breakdown when left in sunlight.

[0028] In addition, air hoses with small diameters were found to create too much resistance to air flow, causing air compressors to burn out and air hoses with large diameters were found to require too much power to create the desired air pressures. Likewise, the thickness of the air hose wall is critical for operation. If the walls are too thick, the hoses becomes heavy and unwieldy but if the walls are too thin the hoses will burst when pressurized. Based on these facts, it was discovered that the optimal outer diameter of the air hoses should be between 9 mm and 15 mm and that the inner diameter of the air hoses should be between 5 mm and 6.6 mm, which allows enough air flow but prevents the air hoses from becoming overly bulky, preventing use by a user. In particular, the air hoses should have an outer diameter of approximately 12 mm and the inner diameter should have an inner diameter of 5.8 mm. As used in the specification and the claims, the term approximately shall mean that the value is within 10% of the stated value, unless otherwise specified.

[0029] Finally, the length of the air hoses is critical for proper operation. In particular, tire whips 110 which are too short can end up with air hoses hanging from the tire air stems, which can cause the air chuck to pop off the tire and cause wear on the tire whips 110. Likewise, when tire whips 110 are too long they have been found to create too much bulk and reduce effectiveness. Therefore, it has been found that the tire whips 110 should be between 25 and 35 inches in length. Preferably, the tire whips should be approximately 30 inches in length.

[0030] In addition, the length of the output air hoses 106 and tire hoses 112 aid users depending on vehicle size. One of skill in the art will appreciate that the length of the output air hoses 106 depends largely on the width of the vehicle for which use is intended whereas the length of the tire hoses 112 depends mainly on the length of the vehicle for which use is intended. For example, for a compact size the output air hoses 106 can be approximately 100 inches long with the tire hoses 112 approximately 100 inches long. For a regular size the output air hoses 106 can be approximately 130 inches long with the tire hoses 112 approximately 130 inches long. For a large size the output air hoses 106 can be approximately 130 inches long with the tire hoses 112 approximately 160 inches long. For an extra large size the output air hoses 106 can be approximately 130 inches long with the tire hoses 112 approximately 200 inches long.

[0031] The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
