Description

The present invention relates to an umbrella stand, its new construction, shaping and design properties with the highest level of security and Effectiveness to perform the task for which it was specifically designed was developed.

The current state of the art, as since Age-old, umbrella stand pieces of furniture covering an area include housed in the wet or damp umbrellas be, the drying of the same by natural Evaporation of the water with which they are soaked takes place. This process is very slow and contributes to Impairment of the substance, which is why in many If the screen opens outside of the umbrella stand drying over a larger fabric surface accelerate; however, this solution is not practical either because the open umbrella takes up a lot of space takes and because also the floor of the apartment or the Local gets damp and dirty.

To avoid these disadvantages that all umbrella stands have are currently known to resolve the issue developed the present invention; it is about an umbrella stand, the most important feature of which is the attachment of devices that are used for heating and Dry damp or wet umbrellas once inside of the umbrella stand are used to serve the Evaporation process of the residual water of the same nigen.

The heating system used to accelerate evaporation is based on hot air convection by using the electrical current in the household and in public Buildings is available.

The desired result is achieved by an electrical one Drive motor and by an air heating resistor; it flows an air flow that is determined by the user depending on the Engine speed and consumption of the electric  Resistance can be regulated; this current is in the Headed inside the umbrella stand container.

Therefore, the main object of the invention is the creation a device that serves as an umbrella stand and also drying the same via an electrical energy source makes.

Below we give a detailed list of the various elements that are specified in applications for invention patent No. 91 01 364 and additional application No. 92 00 211: ( 1 ) air inlet filter, ( 2 ) motor, ( 3 ) access doors, ( 4 ) Interior, ( 5 ) drainage floor, ( 6 ) water storage tank, ( 7 ) housing, ( 8 ) intermediate and distribution chamber, ( 8 a) bores, ( 9 ) heating chamber, ( 10 ) viewing height, ( 11 ) dehumidifying elements, ( 12 ) wheels , ( 13 ) cover, ( 14 ) air vents, ( 15 ) time switch, ( 16 ) cover micro detector, ( 17 ) main switch, ( 18 ) speed and temperature switch, ( 19 ) micro detector for mechanical impulses, ( 20 ) drive indicator light, ( 21 ) Automatic alarm switch, ( 22 ) Thermal protector, ( 23 ) Alarm lamp, ( 24 ) Engine thermal protection, ( 26 ) Air intake and pulse turbine, ( 27 ) Air line, ( 28 ) Moisture detector hygrostat.

Figure No. 1 shows the umbrella stand, the object of this invention is in a partially sectioned perspective view that recognize its internal structure leaves.

Figure # 2 is a partially cut page view of the above device.

Figure 3 is a circuit diagram of the Umbrella stand.

Figure # 4 is an operational schematic of the improved Umbrella stand.

Figure 5 is also an operating diagram of the improved umbrella stand.

In Figure No. 1, ( 7 ) denotes the outer casing of the umbrella stand and ( 4 ) denotes the inner area, which is used to accommodate the umbrellas to be dried, this area being made of a material that, without being damaged, the Resists moisture. It has some devices that make it possible to remove the drops of water that are deposited inside; these consist of a perforated base ( 5 ) which is connected to an inner compartment ( 6 ).

Between the housing ( 7 ) and the area ( 4 ), a chamber is installed, where the heating devices are arranged, which consist of an electric motor and an air heating resistor and are located in a housing ( 2 ), the motor of which drives a screw or turbine, which is located in a housing ( 1 ), which serves to suck in the outside air through the corresponding filter ( 3 ).

The generated hot air flow is led through the line ( 12 ) into the interior of the area ( 4 ) to which it is connected through its lowermost open part ( 13 ).

The outer housing ( 7 ) can take a shape which is suitable for any environment in which the umbrella stand is to be used, including an upper cover ( 8 ) which serves to close off the overall arrangement.

The umbrella stand can accommodate a number of controls that improve its operation, such as. B. Controls ( 9 ) for commissioning and standstill, controller for the drying capacity ( 10 ) and timer to regulate the desired operating time of the device and the subsequent automatic shutdown.

In one alternative embodiment, the area ( 4 ) can be heated by natural convection, ie by transferring the heat to those sectors which are in the vicinity of the container without the used air being driven in any way.

In one of the main versions of the subject of supplementary application No. 92 00 211, shown in Figure No. 2, the improved umbrella stand consists of an outer housing ( 7 ) on which the signaling and control elements of the device are arranged and in the inner part of which are the elements are located that enable its proper operation, for. B. the interior ( 4 ), which serves to accommodate the umbrellas; this area is made of a moisture-insensitive material and has been redesigned with some devices that make it possible to remove the drops that settle inside. These devices are perforated bottoms ( 5 ) which are connected to a lower part for receiving the drops ( 6 ).

On the side parts of the inner area ( 4 ) there is an air distribution system, which consists of a set of holes ( 8 a), which allow the uniform entry of warm air through the periphery ( 4 ), whereby a good performance in the screen drying process is achieved. The arrangement of this distribution system on the basis of holes ( 8 a) also prevents that with a large number of umbrellas inside the drying container ( 4 ) the excitation or the driving of the air on the part of the motor ( 2 ) is made impossible - when saturated this airflow comes out.

With the above-mentioned improvements, the ascent movement of the warm air, since it is lighter than the cold air, is better used to direct the air flow from the lower part of the container ( 4 ) to the upper part of the same and on this route the air is dried; In the initial application, the turbine or motor was positioned in the upper housing part ( 7 ), while in the above-mentioned improvements the motor or the turbine was installed in the lower part of this housing ( 7 ).

In order to prevent blockages of the motor (2), and its range is separated to the container (4) by means of the conduit (27) introduces air through the intermediate chamber (8), (a 8) optimizes the distribution of the air flow through the holes and also the blocking of this motor ( 2 ) is prevented, since this intermediate chamber ( 8 ) is connected on its underside through the air outlets ( 14 ) to the outside environment, which does not impair the drying performance - due to the above-mentioned ascent force.

The electric drive or excitation motor ( 2 ), as described above, is installed in the lower part of the system, with a minimum distance from the inner container ( 4 ) and from the intermediate chamber ( 8 ), in order to avoid any flow rate charge loss and at the same time the installation takes place slightly above the lower part of the container ( 4 ); this is a first safety measure for the correct operation of the umbrella stand, because it prevents water that runs off the umbrellas from entering the motor, even if it should accumulate in the lower part of the device.

The motor ( 2 ) drives an air intake and drive turbine ( 26 ) at one of its end points, which prevents the entry of dirt and foreign bodies through the corresponding filters ( 1 ) attached to the side parts of the housing ( 7 ) at the same time drives the air from the outside to the chamber ( 9 ), where the air heating resistors are located, and this air is conducted to the lower part of the intermediate chamber ( 8 ) via a line ( 27 ).

From the intermediate chamber ( 8 ), the hot air flow is distributed through the corresponding bores ( 8 a) and passed in an ascending direction through the entire inner container ( 4 ), although it would also be possible to attach alignment slats for this air flow or any other system with the same purpose.

In addition to the described mechanism of the motor ( 2 ), which prevents the water from entering the motor, and the lower air outlets ( 14 ) for the warm air in the event of saturation of the device, the safety systems consist of the following elements: Thermal protection ( 24 ) against overheating the engine ( 2 ), which must automatically switch it off, e.g. B. in the case of clogging of the filter ( 1 ).

In addition, the installation of some contacts in the electrical circuit ( 21 ) is provided, which would switch the device off if water accumulates in the lower part of it, outside the droplet container ( 6 ), by switching on an external alarm lamp ( 23 ). If the contact malfunctions, the lower air outlets only need to be set to a low level (so that the water can be drained).

One or more viewing windows ( 10 ) can be attached, which reflect the accumulation of water on the outside, as well as a thermal fuse or a thermostat ( 22 ), whereby the operation of the device is switched off if the temperature inside it rises excessively, in addition to Protection that the motor itself has.

The maintenance systems consist of the following elements. A small drip catcher ( 6 ) located in the lower part of the intermediate chamber ( 8 ) collects a certain amount of water up to a safety limit previously set for each of the possible umbrella stand sizes; it can be removed in the rear part to enable cleaning. For this task and for the maintenance of the entire device, some doors ( 3 ) are attached, which can only be opened if the device was previously switched off by the electrical power source.

For the purpose of moisture absorption, there are some regularly replaceable moisture absorption elements ( 11 ) inside the device, the function of which is to hold back the air humidity before the air comes out again after use through the air outlets ( 14 ).

The outer housing ( 7 ), which is preferably shown in the form of a prism in Figure No. 2, can be given a structure which is suitable for any location of use of the umbrella stand; wheels ( 12 ) for transporting the same can be attached to the desired location, as well as an upper cover ( 13 ) which closes the container ( 4 ) as soon as the umbrellas have been removed or put in and with some outlets ( 14 ) for the used air in its upper or lower part.

For the control systems and controls as well as those there are numerous to improve its function different elements, of which the following lines two are mentioned as preferred systems or elements.

The operating devices can include on and off switches of the umbrella stand to or from the electrical power network, regulators of the speed of the driven air and the temperature of the same, timers for arbitrary control of the drive time of the hot air and the automatic standstill thereof, and position detectors which provide the information for electronic Transfer operational control. With this control system and as can be seen from the electrical circuit diagram in Figure 2 , the following operation can be achieved: When the switch-on control button is in the "mains switch-on" position, the device works and drives the air through the intermediate chamber ( 8 ) into the interior of the screen container ( 4 ) when the cover ( 13 ) is closed for a period that can be set at the time switch ( 15 ).

When the set time comes to an end, the device automatically adjusts the air drive. If the top cover ( 13 ) should open during the air drive, the operation is switched off by the action of the position detector switch ( 16 ) and as soon as the cover ( 13 ) is closed again, the device drives the air for the set time, whereby the cycle is started again due to the parking of a new umbrella. This happens every time the cover is opened and closed again ( 13 ). As soon as the operation comes to a standstill because the set drive period has expired, the cover remains closed so that the warm air inside the container ( 4 ) is not immediately lost. If a screen is removed from the container and no new one is put in, that is, it is not desired that operation be resumed, it is sufficient to open or close the cover ( 13 ) and to switch the device on using the switch ( 17 ) so that it does not start again. Otherwise, if there are still umbrellas inside the umbrella stand and it is desired to continue the drying process, the device starts again when the cover ( 13 ) is closed and the switch ( 17 ) is not switched off.

A light signal in the operating area informs the user at all times while the air is being driven into the container. It is also possible at any time to increase or decrease the amount of air driven by the motor and the temperature of this air by operating a switch ( 18 ) located in the operating area.

Another possible functional system, according to the circuit diagram in Figure No. 4, is to mount a detector in the lower container area, which is marked with ( 19 ), so that when a screen is inserted into the container interior ( 4 ) and with light pressure , a switch-on takes place for a short period of time, which is sufficient to transmit a signal to the timer ( 15 ), from which motor and heating resistor remain switched on for any period of time set. If a new screen is placed in the interior of the container ( 4 ), the cycle repeats.

In this example, the cover ( 13 ) would function as a simple instantaneous switch of the cycle when it is opened and the cycle would be set as soon as it was closed. There were no changes to the other elements with respect to the previous example, with the exception of the timer ( 15 ), which would have to perform a different function, but which would be compatible with those currently on the market. With this version, it is also possible to remove the top cover of the system, although this may impair the functioning of the device because the air drive would not stop when a new screen is placed; the screens are also visible inside.

According to Figure No. 5, a hygrostat ( 28 ), i.e. a moisture detector, is one of the elements already mentioned. This makes it possible that when moist screens are inserted into the container interior ( 4 ), this moisture detector works as an automatic switch of the system and actuates the air drive by the motor and the heating by the heating resistors. Once the interior is dry, the same detector device would stop operating the umbrella stand. This hygrostat ( 28 ) can be regulated as desired with regard to the percentage of the relative air humidity from which it gives the operating signal and also with regard to the adjustment value. In this version, the timer ( 15 ) and the top cover ( 13 ) can also be used, although the timer ( 15 ) is no longer necessary.

In other alternative embodiments, the operation of the Umbrella stand can be automated by other methods, such as B. by attaching photocells, infrared Position detectors and similar components that are not shown here individual as examples because they are the do not affect the protection sought.

Equivalent designs are considered to be those which use the heating of the area and thus the drying process of the screens by means of heat transfer by means of non-forced heat conduction and / or convection for the same function, ie in which the heat is transferred without the air being driven in any way becomes; some heating devices are simply attached around the screen container, and the whole system can correspond to the description above, but without a drive or excitation motor ( 2 ) and with a different mounting of the heating devices.

In another, equivalent design, the heaters would be omitted, which would speed up the evaporation process of the residual water, since the screens are exposed to a better circulation of the surrounding air by the action of an engine and an air drive turbine. However, this would mean a loss of umbrella stand performance in relation to the model described above, because the evaporation is improved with the temperature, but this variant can also be implemented. In this case, it would be sufficient to remove the heating resistors which are located in the heating chamber ( 9 ), the remaining elements of the described model remaining usable.

After looking at the illustrations and explanations, the we have given, it is clear that the additional Patent application, the reason for this description represents a simple and effective construction offers that with great ease in practice can be implemented and without a doubt a new one Represents industrial product.

After having adequately described what from this patent application and the additional patent application exists, according to the attached plans, it should be understood that any detailed changes can be made to it, which are considered appropriate; with those made Changes are pure form variations that the essence of the additional patent application, which in the following claims is not summarized change.
