Description

DEVICE FOR SEALING A TIRE WITHOUT CHAMBER INSIDE A WHEEL RIM BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a pneumatic device for use in sealing a tire without an interior chamber to a wheel rim. 2. Description of the related art When a tire is installed without an interior chamber that is to be inflated in a wheel, typically the tire moldings or heels do not seal against the wheel rim. Accordingly, when pressurized air is supplied to the valve stem of the wheel, air escapes from the interior of the tire through the space between the tire moldings and the wheel rim, which makes it difficult to inflate the tire. This problem is even more acute when it comes to larger tires / wheels, for example, those used in trucks and equipment to move heavy-duty dirt, due to the increased weight and dimensions of tires. Since such tires usually inflate while in a horizontal orientation, the uninflated tire tilts, which increases the size of space through which the air escapes. In an attempt to solve the problem described above numerous methods and tools have been developed. One method is constituted by the ignition inside the tire. The resulting explosion can usually temporarily seal the tire moldings of the wheel rim so that the tire can be inflated. This technique is dangerous and can lead to the death of people. It is also known to apply a soapy liquid to the tire moldings to assist in sealing the moldings of the tire to the wheel rim. This technique is not always successful, particularly with larger tires. It also results in the interior of the tire being coated with the soapy liquid, which makes it difficult to apply a patch to the interior of the tire if the tire is punctured during normal use. Tire sealants have been developed which rapidly inject air into the tire, between a tire molding and the wheel rim, so that it seals the tire moldings to the wheel rim.

Some of these tire sealing devices require the user to place a ring-shaped tubular member around the circumference of the space formed between the tire molding and the wheel rim. Examples of sealing devices for tires having curved tubular members are shown in U.S. Patent Nos. 3,552,469; 3,683,991; 3,814,163; 3,851,695 and 5,247,982. The molding of a tire without an inner tube on the wheel rim does not easily fit on tires or rims of different sizes. These devices also require a substantial amount of time in the preparation of the equipment before the sealing process. Other devices for injecting air into a tire between the tire molding and the wheel rim are described in U.S. Pat. Nos. 4,744,402; 5,056,576; 5,072,765; 5,168,911 and 5,456,302. These devices are expensive and bulky (and therefore not easily portable - and certainly not a "manual" device) and are annoying to use. U.S. Patent No. 5,570,733 to Desparois et al. describes a manual tool for inflating tires. The tool includes an injection head for directing a high-volume, valve-controlled, high-pressure air jet into the cavity of a deflated tire. The tool includes an ON / OFF valve that is bypassed to the OFF position for safety purposes and that also includes pins (poles) to help place the tool on the wheel rim. Although the ON / OFF valve provides a limited safety function, it does not prevent excessive inflation of the tire. The clips do not hold the tool and the rim together, and therefore does not prevent the tool from being ejected inadvertently away from the wheel (and towards the user) when an air discharge is supplied from the tool, which can lead to damage. U.S. Patent No. 3,866,654 to Duquesne discloses a device for inflating tires without an inner chamber. The device provides a conventional tire inflation hose, which is to be attached to the valve of the tire during inflation. However, the device lacks a multidirectional nozzle and its design leaves open the possibility that the nozzle is stuck between the tire and the rim, and in this way a complete seal is avoided. The device also suffers from all the disadvantages described above with respect to U.S. Patent No. 5,570,733. U.S. Patent No. 5,072,764 to Ochoa discloses a device for sealing tires without an interior chamber using a manually operated valve to release an air discharge from a storage tank. The device has a pressure limiting valve, but only limits the pressure in the tank and not in the tire, which leaves the tire exposed to possible excessive pressurization.

BRIEF DESCRIPTION OF THE INVENTION An object of the invention is to provide a tire sealing device having a nozzle designed to efficiently discharge pressurized air into a tire to be sealed to a wheel rim. Another object of the invention is to provide a sealing device for tires that prevents excessive inflation of a tire. Another object of the invention is to provide a tire sealing device that protects the user from hazards. In order to obtain the above and other additional objects, and in order to solve the drawbacks in the prior art, a tire sealing device, according to one aspect of the invention, includes a split nozzle designed to discharge in a manner Efficient and safe pressurized air in a tire so that the tire can be sealed to the wheel rim. The split nozzle directs the pressurized air to two diverging directions so that when the nozzle is inserted divided between a tire without inner chamber and a wheel rim, the air exiting through the divided nozzle will travel in opposite directions around the rim of wheel and inside the tire. Preferably, the tire sealing device is made of structural material (eg metal) with welded components together, as well as couplings, pressure gauge, valves (ON / OFF and / or safety) and hoses in fluid relation to each other. The tire sealing device may have a hose for transporting air with an inner conductor and a split nozzle. The inner duct is connected to a source of pressurized air. Preferably, the hose for transporting air has first and second chambers that connect the inlet conduit with opposite sides of the split nozzle. A connector connects the inlet duct to the pressurized air source. Preferably, a manually operable ON / OFF valve is provided. The ON / OFF valve can be attached to the inlet duct to allow the user to control the supply of pressurized air to the housing. A gauge that measures pressure can also be attached to the connector. Preferably, one end of the inflation tube is attached to the connector, while the second end of the inflation tube can be attached to a tire valve in the traditional manner. The inflation tube discharges the pressurized air in the tire to inflate the tire (through the tire valve), once the tire has been sealed to the wheel rim. In a preferred embodiment, a pressure relief safety valve or "exhaust valve" is provided between the pressurized air source and the housing and inflation tube. This can be accomplished by providing the safety valve in the connector upstream of the point where the inflation tube is attached. The safety valve prevents excessive pressurization of the tire through the nozzle or through the inflation tube. A fixed support flange adjacent to the split nozzle engages the wheel rim and provides support and positioning of the device during operation.

According to another aspect of the invention, there is provided a manual tire sealing device having a housing for transporting air and a nozzle, with a clamping mechanism that allows the device to be fixed to the wheel rim. When attached to the wheel rim, the clamping mechanism prevents the tire sealing device from being ejected away from the wheel rim during the discharge of pressurized air through the nozzle. Therefore, the clamping mechanism provides a safety function. Preferably, the clamping mechanism is attached to (eg, by welding) the air-transporting housing can be detachably attached to the wheel rim so as to secure the housing to the rim during sealing of the tire. The clamping mechanism is operable between clamped and released positions. Preferably, a clamping member, for example a clamping bolt, can be provided so as to clamp the clamping mechanism in the clamped position. The clamping mechanism can also include an adjustable member so that the clamping mechanism and therefore the tire sealing device can be used with wheel rims having various different sizes.

The resulting tire sealing device seals the entire tire more efficiently as compared to conventional tire sealing devices. In addition, the multiple safety features include the safety valve of escape and the mechanism of subjection reduces the possibility of damage to the user and excessive inflation of the tire. Accordingly, the present tire sealing device can be used more easily, safely and with greater confidence.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in relation to the following drawings in which like reference numerals designate similar elements, and wherein: Figure 1 is a perspective view of the tire sealing device, in accordance with a preferred embodiment of the present invention , the device is in a position in which it is attached to the wheel rim; Figure 2 is a partial sectional view of the tire sealing device of Figure 1 in the clamped position; Figure 3 is a view similar to that of Figure 2, showing the tire sealing device in the released position; Figure 4 is a front view of the nozzle divided in the device of Figure 1; and Figure 5 is a side view, in partial section, showing the tire sealing device positioned in relation to a wheel rim and a tire for performing the sealing operation of the tire moldings against the rim flange.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Figure 1 is a perspective view of a tire sealing device, according to a preferred embodiment of the present invention. The tire sealing device 10 includes a housing 20 for transporting air having a conduit 22 inlet and a split nozzle 30. A source of pressurized air and an air line, none of which is shown, are in communication with a duct 22, by a connector 40. The connector 40 has a first, second and third apertures 42, 44 and 46, respectively. The first opening 42 is attached to the air pipe and to the pressurized air source. The second opening 44 is joined to an inlet duct 22. The third opening 46 will be discussed in more detail in the following. As will also be discussed in more detail in the following, when pressurized air is supplied to the housing 20 and discharged through the split nozzle 30, an instantaneous increase in pressure within the tire 12 urges the moldings 14 of the tire to be sealed with the flange 18 of the rim (see Figure 5). With reference to Figure 4, in a preferred embodiment, the housing 20 is made of components of structural material (eg metal) that are welded together. A dividing wall 29 extends longitudinally through the center of the housing (i.e., from the inlet duct 22 to the nozzle 30). As a result, the housing 20 has first and second chambers 24 and 26 that respectively connect the inlet conduit 22 with a first nozzle 32 and a second nozzle 34 of the divided nozzle 30. In the first nozzle 32 and the second nozzle 34 direct pressurized air in two diverging directions so that the split nozzle 30 is inserted between a tire 12 without inner chamber and the wheel rim 18 (as shown in Figures 1 and 5), the air discharged through the divided nozzle 30 It will travel in opposite directions around the rim 18 and inside the tire 12. As described above, this causes the tire to expand rapidly so that the tire molds temporarily seal against the wheel rim. As additional air is introduced into the tire, for example, through the valve stem of the wheel, the tire is inflated to the desired pressure, and a seal is maintained between the tire and the wheel. As can be seen better in figure 5, the split nozzle 30 is configured to be easily inserted between the tire 12 and the rim 18 before sealing, as well as for easy removal after sealing. It is considered that the split nozzle allows the tire to seal more quickly against the wheel rim, than would be possible with simple, straight and unique nozzles. The split nozzle ensures that the pressurized air will be directed in two opposite directions around the wheel rim and into the tire. This causes the tire to expand rapidly and seal faster, possibly due to increased turbulence caused by the two air currents and / or the fact that none of the single air stream needs to travel completely around the circumference of the air. wheel. Returning to FIG. 1, an ON / OFF, manually actuatable valve 38 is attached to the inlet duct 22 and allows the operator to control the supply of pressurized air to the housing 20. In the illustrated embodiment, the ON / OFF valve 38 OFF is a rotatable valve, commercially available. Other ON / OFF valves may be used, including valves that are diverted to the OFF position as described in U.S. Patent No. 5,570,733. Preferably, a gauge for measuring pressure, such as a gauge 36 for measuring pressure, is attached to a third opening 46 to connector 40 and measures the pressurized air leaving the split nozzle 30. A first end of an inflated tube 48 is also attached to a third opening 46 of the connector 40. A second end of the tube 48 includes a device 52 that can be attached to the tire valve 16 in a standard manner. The inflation tube 48 allows the tire to inflate during the sealing process. Of course, a separate inflation tube can be used from a separate source of air as an alternative. However, the configuration shown in Figure 1 is convenient, easy to use and reduces the amount of equipment that needs to be handled. Preferably, the connector 40 includes a localized pressure limiting valve, for example, upstream of the openings 44 and 46. Such a pressure limiting valve prevents a predetermined level of maximum pressure reached within the tire from being exceeded, for example, 3.5 kg / cm2 (50 psi). As an additional safety precaution, the pressure relief valve 56 or "exhaust valve" may be provided in fluid communication with the housing 20. When the pressure within the housing 20 exceeds a maximum level (eg, 3.5 kg / cm2 (50 psi)), the valve 56 is opened, whereby excessive pressurization of the tire 12 is avoided. Figure 2 is a partially sectioned, side view of the tire sealing device of Figure 1. As shown in FIG. can see from Figure 2, the support flange 58 is located above the split nozzle 30. The flange 58 engages the wheel rim 18 and provides support to the device 10 during operation so that the user does not Holds the entire weight of the device. The flange 58 is also shaped and positioned so that the end of the nozzle 30 is optimally located during use, as shown, for example in Figure 5. Another aspect of the invention relates to a fastening mechanism for Fasten the entire tire sealing device to the wheel during the sealing process. The clamping mechanism improves the safety of the tire sealing device by preventing it from being ejected accidentally away from the wheel (or vice versa) when the pressurized air discharge is supplied from the tire sealing device. Preferably, the clamping mechanism is used with a tire sealing device having a split nozzle described above, so as to take advantage of both characteristics. The clamping mechanism can also be used with sealing devices for tires that have different nozzles to the split nozzle, for example, with single simple nozzles as described in some of the patents mentioned above. A preferred design for the clamping mechanism will now be described. The clamping mechanism 60 is joined, (for example, welded) to the housing 20. The clamping mechanism 60 can be detachably attached to the wheel rim 18 to secure the housing 20 to the rim 18 during sealing of the tire 12 to the rim. The clamping mechanism 60 is operable between a clamped position (shown in Figure 2) and a released position (shown in figure 3). The clamping mechanism 60 includes a slidable member 62 which is axially slidably guided relative to the housing 20 by a guide member 70. The guide member 70 is attached to the housing 20 and flange 58. In the illustrated embodiment, the guide member 70 is a hollow tube or sleeve. When in the clamped position, the slidable member 62 is in a retracted and fixed position relative to the housing 20. The first end 64 of the sliding member 62 includes an adjustable member 66. The adjustable member 66 fixes the slidable member 62 to the rim 18. In the illustrated embodiment, the adjustable member 66 is a bolt or bolt having a position that is adjustable by bolting it through the end 64 of the slidable member 62. Because the member 66 is adjustable, the tire sealing device can be easily used with different types and sizes of wheel rims. Other structures, in addition to the bolt or screw, can be used as the adjustable member. Now the structure moving the slidable member 62 between the retracted (clamped) position shown in Figure 2 and the extended (released) position shown in Figure 3 will be described. The second end 68 of the slidable member 62 connects to a handle member 72 by an articulated member 78. The hinged member 78 is pivotally joined to the handle member 72 and to a member 62 slidable at the pivot points 77 and 79, respectively.

The handle member 72 is pivotally connected to the housing 20 at the pivot point 73 and is movable between the clamped and released positions. When in the clamped position, the handle member 72 extends upwardly from the housing 20, as shown in Figure 3. This extends the member 62 slidable outward, away from the mouthpiece 30 so that the mouthpiece 30 it can be placed between the tire and the wheel at the first end 64 and the adjustable member 66 can be placed inside the wheel easily, as shown, for example in Figure 5. Next, the user simply pushes the handle member 72 towards down, to the position shown in Figure 2. This retracts the first end 64 of the slidable member towards the nozzle 30 so that the tire sealing device is secured to the wheel. Any adjustment that may be necessary is facilitated by rotating the adjustable member 66. A fastening member 76, for example a bolt, may be placed in the openings 74 and 75 provided in the handle member 72 and the hinge member 78, respectively, to thereby retain the gripping mechanism 60 in the clamped position. . The fastening member 76 can be attached to the housing 20, for example, by a chain. When the clamping member 76 is removed, the clamping mechanism 60 can be moved to the released position, whereby the tire sealing device 10 is allowed to disengage from the wheel rim 18. Figure 5 is a view showing the tire sealing device 10 positioned in relation to a wheel rim 18 and a tire 12 to carry out the sealing operation of the tire moldings 14 against the rim 18. In operation, the user moves the member 76 of clamping from the openings 74, 75 of the handle member 72 and the hinge member 78. This allows the operator to rotate the handle member 72 to a released position which in turn extends the slidable member 62 so that the adjustable member 66 can engage the wheel rim 18. The handle member 72 is subsequently rotated to the clamped position so that it retracts the slidable member 62 so that the adjustable member 66 abuts the rim 18. The clamping member 76 can subsequently be positioned through the openings 74, 75 , so that it holds the clamping mechanism 60 in the clamped position. The inflation tube 48 is attached to the valve rod 16 in the usual manner. If pressurized air is supplied to the inflation tube, it will enter the tire. However, because the tire is not sealed to the wheel rim, the tire will not be inflated.

Thereafter, the operator rotates the valve 38 to the ON position, thereby allowing a high pressure air discharge to be supplied into the housing 20. The air enters the housing 20 through the inlet duct 22 and passes through. of the first and second chambers 24, 26. Subsequently air exits through the first and second nozzles 32, 34 of the split nozzle 30 in diverging directions around the rim 18. The pressurized air immediately impels the moldings 14 of the tire to seal against the rim 18. Subsequently, the tire is inflated by means of the inflation tube 48. The tire can be inflated completely to the desired pressure or can be inflated to a sufficient pressure to prevent the tire from sealing with respect to the wheel. If the pressure in the housing 20 becomes too high, the pressure relief valve 56 will open to prevent excessive pressurization of the tire 12. Subsequently, the operator turns the valve 38 to the OFF position thereby suspending the flow of pressurized air Subsequently, the operator uncouples the inflation tube 48 from the tire valve 16. The operator then removes the clamping member 76 from the openings 74 and 75, thereby allowing the user to rotate the handle member 72 to a released position. After the tire sealing device is removed, the tire can be further inflated to the desired pressure if necessary. The tire sealing device can have various sizes, based on its proposed use. A device suitable for use with standard sized truck tires is constructed with a length of approximately 38 cm (15 inches), a width of approximately 15 cm (6 inches) and a height of approximately 5 cm (2 inches). This device weighs approximately 7.2 kg (16 pounds). A device of smaller size would be suitable for car tires. A larger device and / or multiple devices could be used with tires for heavy equipment to move earth. Although this invention has been described in relation to a specific embodiment thereof, it is clear that many alternatives, modifications and variations are apparent to those familiar with the art. Accordingly, it is preferred that the preferred embodiment of the invention, as set forth herein, be illustrative and not limiting. Various changes can be made without departing from the spirit and scope of the invention, as defined in the following claims.
