Description
KIT, WITH AN IMPROVED GAUGE, FOR REPAIRING AND INFIATING INFLATABLE ARTICLES, AND RELATIVE METHOD
TECHNICAL FIELD The present invention relates to a kit, with an improved gauge, for repairing and inflating inflatable articles .
A recent market trend is to replace the spare wheel of a vehicle with a kit for repairing and inflating a flat tyre without having to remove the tyre from the hub.
The kit normally comprises a compressor connectable to a power outlet; and a canister of sealing fluid connectable in series between the compressor and the flat tyre.
In the event of a flat tyre, the compressor injects the sealing fluid and then inflates the tyre.
BACKGROUND ART The compressor is equipped with a gauge for controlling the pressure of the repaired tyre.
When repairing the tyre, the pressure reading on the gauge fluctuates and shows high peaks, which has been found to give the user the impression that the kit is nor working properly and that the tyre cannot be repaired.
DISCLOSURE QF INVENTION
It is an object of the present invention to provide a kit designed to eliminate the above drawback.
According to the present invention, there are provided a kit as claimed in Claim 1, and a method as claimed in Claim 8.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred, non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
Figure 1 shows a view in perspective of a kit in accordance with the present invention;
Figure 2 shows a circuit diagram of the Figure 1 kit;
Figure 3 shows a quality graph of pressure as a function of compressor operating time.
BEST MODE FOR CARRYING OUT THE INVENTION Number 1 in Figure 1 indicates as a whole a kit for repairing and inflating inflatable articles, and which comprises a casing 2; a compressor assembly C (shown schematically in Figure 2) housed in casing 2; and a canister assembly 3 connected releaεably to compressor assembly C.
More specifically, casing 2 comprises a substantially parallelepiped-shaped portion 4 for housing compressor assembly C; and a projecting portion
5 projecting from the front of portion 4 to define a seat for at least partly housing canister assembly 3.
Canister assembly 3 contains tyre puncture repair sealing fluid, and comprises a bottle 6 turned upside down in use; and a hose 7 connected to bottle 6 to feed the sealing fluid into the tyre.
Kit 1 also comprises a second hose 8 connected directly to compressor assembly C to inflate the tyre without injecting sealing fluid. Kit 1 also comprises a knob 9 for selecting a repair mode, in which hose 7 and bottle 6 are connected to compressor assembly C; a pressure regulating and inflation mode, in which hose 8 is connected to compressor assembly C; and a compressor assembly C OFF mode . Figure 2 shows a diagram of the fluid circuit inside casing 2 of kit 1. The delivery side of compressor assembly C is connected to a one-inlet, two- outlet valve 20 by a conduit 21 inside casing 2.
Valve 20 is switched by knob 9, and provides for directing compressed airflow to bottle β to repair the tyre, or to hose 8 to inflate an inflatable article.
More specifically, one outlet of valve 20 is connected to an inlet of bottle 6 by a conduit 22 inside casing 2, and the other outlet is connected to hose 8 by a conduit 23 also inside casing 2. Conduits 22, 23 are therefore connected parallel with respect to valve 20.
Kit 1 also comprises an 1OR1 fluidic member 24 having two inlets connected to conduits 22, 23
respectively, and an outlet connected to a pressure sensor 25.
Pressure sensor 25 is therefore always connected to the higher-pressure conduit 22, 23. Pressure sensor 25 sends a signal P to a control device 26 inside casing 2.
In a preferred embodiment, signal P is electric, and control device 26 is electric or electronic, and is powered by a plug S which also powers compressor assembly C.
Kit 1 also comprises an LCD screen 27 connected to control device 26 to display the pressure measured by sensor 25 and so enable optimum user operation of compressor assembly C. In a preferred embodiment of the present invention, control device 26 is designed so that pressure signal P is only displayed on screen 27 when compressor assembly C is activated in repair mode, i.e. in which compressor assembly C is connected to canister assembly 3. Control device 26 preferably features a counter, which is activated when the compressor assembly is turned on by the user, and so serves as a timer. Control device 26 is programmed not to display the pressure measured by sensor 25 until the counter reaches a given threshold value. In other words, control device 26 cuts off display of pressure signal P until the counter reaches the threshold value .
The threshold value is programmed when
manufacturing the kit, and represents the time interval in which the pressure signal stabilizes. Given the airflow of compressor assembly C and the volume of bottle 6, this time interval can be calculated easily. Control device 26 is also designed to determine the setting of fluidic member 24, so that, when hose 8 is connected to the inflatable article, the counter is disabled, and the pressure signal is transmitted to screen 27 even if compressor assembly C has not yet been turned on. In this way, the user can check the pressure of the inflatable article without turning on compressor assembly C.
The signal from pressure sensor 25 has been found to indicate the actual tyre pressure substantially when bottle 6 is nearly or completely empty.
Figure 3 shows a quality graph of the pressure measured by pressure sensor 25. The first peak indicates a pressure value not corresponding to the actual tyre pressure. The threshold value, after which to display the pressure measurement by pressure sensor 25 on screen 27, is preferably set about the minimum point substantially corresponding to when bottle 6 is empty.
The advantages of the present invention will be clear from the above description of kit 1. In particular, delaying display of the pressure value on screen 27 provides for displaying a more stable pressure value than would be shown as soon as compressor assembly C is turned on with kit 1 operating in repair
mode.
By means of fluidic member 24, a single pressure sensor 25 can be employed.
Using a timer implemented in control device 26 is easy to achieve and reduces manufacturing cost.
Clearly, changes may be made to the kit as described and illustrated herein without, however, departing from the scope of the present invention.
In particular, the control device may be mechanical, and the screen analogical.
Control device 26 may also be programmed so that pressure signal P is first displayed, then not displayed temporarily, and eventually displayed again. In this case too, control device 26 cuts off display of the pressure signal on screen 27.
