Description of the invention (1) Field of the invention The present invention relates to a testing device, which is suitable for testing whether an impervious surface which can reach a required level of impermeability is actually reached. The invention is special, but not unique, and is applied to some devices to test the surface of buildings and other building structures, and to test their ability to resist wind and rain. The invention also includes a method for testing the above-mentioned surface ' using the device. BACKGROUND OF THE INVENTION The external surface of a building structure is expected to act as an impermeable barrier to block out atmospheric environmental substances such as wind and rain. Unfortunately, the structure does not fully provide this protection. The cause may be due to poor construction or construction technology, or may be the result of poor design. Generally, the points of entry for wind, water vapor, or windows, doors, wall cracks, skylights, and other holes or entrances. The range that wind and rain can enter is of course wide. The cost of repairs is considerable. A method has been established for testing surfaces, and the weather resistance specifications of the surface are in A. A. M. A. 5 01. 2 (Aluminum Manufacturing Association of America). This test basically requires a person to spray water from a garden hose on the surface of a building by hand. Although A. A. M. A. 5 01. 2 standards are developed with specifications and the water pressure required for the hose, the user only needs to spill the surface back and forth for five minutes. Therefore, the amount of water splashed on the surface is not fixed with the movement of each test, because it is determined by the user such as

SUMMARY OF THE INVENTION According to the present invention, there is provided a device suitable for testing an impermeable surface comprising: a drain outlet connectable to a source of liquid, the liquid outlet port directing liquid from the source to the surface to be tested; an air flow generator for generating The airflow to the test surface; among them, the liquid outlet and the airflow generator can simultaneously guide the liquid and airflow to the same side of the surface to be tested to confirm the actual impermeability of the surface. It is preferable to provide a reaction method in the above-mentioned device to counteract the reaction force caused by the air current acting on the surface during use. This counteracting force method may be formed by a secondary airflow generator that generates a secondary airflow to counteract the aforementioned reaction force. In another aspect of the present invention, when the device is placed close to the surface to be tested, the suction force generated by the air entering the secondary airflow generator may be selected from the airflow acting on the surface to be tested by the airflow generator.

In use, when the device is placed close to a surface, the force generated by the airflow acting on the surface is preferably exactly balanced with the suction generated by the gas entering the device through the suction port. In use, when the device is placed near the surface, it is best to establish a mass balance between the amount of gas entering the suction port and the amount of gas pouring out through the water outlet. When the liquid and air flow are directed to the surface to be tested At this time, the device can maintain a general equilibrium position on this surface. Preferably, the air inlet and outlet can be arranged and applicable. In use, when the device is placed near the surface to be tested, a large amount of airflow directed to the surface through the water outlet can be re-entered through the inlet. Device. The suction port can be adjusted and arranged in a direction opposite to the direction of the air flow exiting through the discharge port to allow gas to enter the device. The air suction port and the discharge port may preferably be provided on the same side of the device. In order to facilitate the discharge of air through the discharge port, it is preferable that the air flow direction is opposite to the suction inlet direction. Preferably, the air suction port surrounds the air discharge port, and the air discharge port is preferably placed in the air suction port and is concentric with it.

Most of all, the liquid discharge port is placed in or in the air discharge port. In this way, the air flow from the air discharge port can direct the liquid to the surface to be tested. To guide the flow of gas from the suction port to the grate outlet, an inclined surface may be provided at the junction of the air suction port and the air exhaust port.

Page 8 444 1 22 V. Description of the invention (6) According to another aspect of the invention, testing a surface to be impermeable includes the following steps: placing the test device near the surface to be tested; and using the device while guiding the liquid and An airflow is directed to the same side of the surface to determine the actual impermeability of the surface. In this method, it is best to place the device close enough to the surface to be tested, so that a large amount of airflow from the device can flow into the device through the air suction port, and the amount of air entering the device and the amount of outflow are in the device. A mass balance is established in the device. When liquid and airflow are directed to the surface, the device and the surface can maintain a general equilibrium position. The use of the word "surface" does not mean that the surface must be flat. 1 For example, the invention can be used to test non-planar cracks and connections in buildings. It must be mentioned that a surface that is impermeable does not imply that the surface is completely waterproof and / or impermeable. The invention is not limited to a particular degree of impermeability. Impervious standards can be set by special designs, such as those set by the designer of the building. The invention can test whether the surface meets the prescribed standards. To fully understand the present invention, reference will be made to the examples and the drawings to describe the preferred embodiments of the present invention, in which:

Page 11 444122 V. Description of the invention (9) As shown in the figure, Figure 1 is a perspective view of an example of a test device suitable for testing impervious surfaces, and Figures 2 and 3 are sectional and front views of the illustrative example, respectively. Illustration. All of these test devices are manufactured to be suitable for testing impervious surfaces, numbered 10. For example, the joints between doors and windows in a building must be properly sealed to resist substances such as wind and rain. The test device 10, in fact, aims to test whether the surface is properly constructed to achieve the required degree of sealing. Figure 4 shows the test device 10 ° placed near the test surface 15 in use for the test surface 15 resistance to rain and wind. This test device 10 simulates the rain and wind environment as follows: The wind environment simulates the wind environment. The device 10 provides a controllable simulation of an airflow generator adapted to direct the airflow to the plane 15. In this example, the airflow generator combines the components and features to provide air flow to the plane 15. The air flow generator provides an air suction port through which air flows into the device and an air discharge port that guides the air flow toward the plane 15. The air intake and exhaust ports in the example are formed and shown by the cover structure of the device 10. This example device includes one channel contained in another channel. Referring to FIG. 3 or FIG. 4, the inner surface of the outer casing 65 and the outer surface of the inner casing 75 serve as air.

Page 12

------ 444122 V. Description of the invention (ίο) The suction channel of the suction port 60. The inner surface of the inner case 75 is wound around an air discharge passage as an air discharge port. Therefore, it is preferable that the air suction port surrounds the peak air discharge port. In this example, the air discharge port is located inside the air suction port and is concentric with it. Although it is also conceivable that another less suitable configuration of the sangria 'is to surround the air exhaust port, the air intake at this time will be located inside the air exhaust port and placed on a concentric axis with it. In the examples in Figs. 1 to 4, the "empty 1 inhalation 0" and the air exhaust port are illustrated in a cross section II). However, the present invention is not limited to the circular design, because the actual cross-section shape does not limit the energy supply of the device. The cross section of the air intake D and the air exhaust port can be selected as square, rectangular or other appropriate shapes. In the example, air is drawn in to include a single cylindrical conduit. However, it is also conceivable that in order to introduce air into the device, the air suction port may be connected by one or more ducts. In the illustrated example, the airflow generator includes a method of driving a rotor 50 with a diesel motor 40 to generate an airflow. Other types of motors and engines can also be used. The motor can also be electric. As shown in Fig. 2, a motor 40 in the form of an airflow generator is installed in the air discharge port passage 70. The airflow generator provides power to move the moving air flow through the device ^ In different examples, the airflow generator can be installed in the air suction port and provide motion, and the same is the flow of air through the device. In a further example, an airflow generator can provide a variable rotor speed. The AC motor is a variable speed application that typically breaks. Motor speed changes can be used to simulate changes in wind speed. Figures 1 to 6 · The examples illustrate the use of a two-bladed propeller and multi-leaf spiral music.

笫 13 tribute 444122, description of invention (π) is used to generate strong airflow according to actual application requirements ^ Rain environment simulation Because the device 10 provides a liquid discharge port that can be connected to a liquid source (not shown in the group), it can be used in a rain environment Simulation. In a better illustrative example, the liquid discharge port is of the nozzle 20 type. These nozzles are located in the first tube across the opening of the device. This narrow, elongated catheter 30 is clearly visible in the perspective view of FIG. ) Conduit 30 uses a hose to connect the nearby faucet to the water source. The water source can be from the outside or a separate tank, especially to provide the required liquid source. The liquid discharge port is arranged to be suitable for directing liquid from the source to the surface 'in order to simulate the effect of water spray on the surface. Fig. 4 illustrates the spraying action of liquid from the nozzle 20 'as shown by the dotted line flowing out of the duct 30 through the nozzle 20. The nozzle is located in or on the air discharge channel 70, so the liquid gas is directed from the air discharge port to the surface. The liquid flowing from the liquid outlet is variable, either by manual control of the faucet at the liquid source or by an electromechanical control (not shown). For example, 'the mechanism of an adjustable valve is used to control the amount of liquid flowing from the air discharge port. This control valve can be fitted with a pressure gauge to control the power and / or amount of water sprayed from the nozzle 20. The mechanism of this valve can be in any form to provide the above functions. ’,.

444122 5. In the description of the invention (12), it is impossible to quantify the changes. A time device or electronic control circuit can be used to control changes in the rate of liquid and air flow generation in the device. Simultaneous rain and wind simulation device 10 can simultaneously guide the liquid from the liquid discharge port and the air flow generated by the air flow generator to the surface to be tested. Therefore, the device can simulate the effects of a natural stroke and rain on this surface at the same time. Of course, the device can direct liquid or gas flow to the surface to be tested at one time. But it is important that this device has the ability to guide air and water simultaneously, so it can simulate the effects of wind and rain on the surface to be tested at the same time. Flow of air through the device Referring to FIG. 4, the flow of air from the inlet port passage 60 to the discharge port 70 is shown in dotted lines. In the illustrated example, the direction in which the air enters the air intake of the device is the direction in which the air exits the air. In this device, the air intake and exhaust ports are on the same side. Taking the orientation in Figure 4 as a reference, the air moves to the right through the suction channel 70, and then back to the left to guide the discharge channel. Therefore, after the air passes through the suction port and then reverses, it can be sent out through the discharge port. From Figure Two and

Page 15 444122 V. Description of the invention (13) As can be seen in Figure 4, there is a flat inclined surface 80 close to the junction of the air suction port and the discharge port in order to guide the air from the suction port to the discharge port. The purpose of this slope is to reduce the turbulence caused by the air reaching from the various parts of the suction port 60 and the pooling behind the device 10. EXAMPLES In Figures 1 to 4, the air flow passes through the air flow generator, and basically passes through the air suction port along the straight path and is discharged through the discharge port. No eddy currents are generated in the inlet channel or the outlet channel. However, there are many more examples. For special design requirements, the air flow can be controlled to generate vortices at the air intake or exhaust. Regarding the adjustability of the air suction port for the air suction port The position of the air discharge port for the air suction port is adjustable. Referring to Fig. 2, the inner case 7 5 is fixed in the outer case 65 in an adjustable manner by using a support rod 6 7 fixed by screws and nuts. Therefore, the inner case 75 can be selectively placed along the longitudinal axis of the outer case 65. This adjustable performance, in use, can be related to the air inlet, the air outlet can be adjusted closer to or away from the surface. For example, when the inner shell 75 is placed close to the opening of the outer shell 75 (that is, close to the right-hand side in the figure) in use, it means that the air exhaust port 70 can be placed near the surface 15 and connected. Down, you can cause the airflow to exert a greater force on the surface. Similarly, the air exhaust port is more retracted back to the housing 6 5 (that is, near the left hand side in the figure), so that the airflow will reduce the effect on the surface in the middle. In relation to the air intake, the stop of this air exhaust position

Page 16 4441 2 2 V. Description of the invention (14) Integrity 'allows the user to change the force of the airflow directed to the surface. In other examples, there are more improved methods that can be used to adjust the relative to the air intake , The location of the air outlet. For example, in the outer casing 'the inner casing 75 can use the rack and pinion to move the position'. In this way, the parts can be moved incrementally instead of stepwise without disassembling the entire device. Stability of the device position in use A particular advantage of the present example of the present invention is that when constructed in a fairly compact housing and sufficiently lightweight components, the device will be portable and ready for transport. Examples of this device can be supported by different kinds of shelves. However, 'the present invention's portable or at least easy to suspend or transport should be particularly beneficial, because in many cases' the surface of the building being tested has a large test area, for example, the large plane of a skyscraper glass Curtains must be tested by climatic tests. In some examples, particularly lightweight, portable or suspendable, the problem of directing the airflow toward the surface will cause problems due to the tendency of the airflow to focus the device away from the surface. This phenomenon occurs because the air current acts on the surface to generate a reaction force, and there is a tendency to drive the device away from the surface. This problem occurs especially when the device generates a strong airflow to the surface to be tested, the reaction force of the airflow has a significant impact on the device when the weight is sufficiently light. Therefore, 'such an example of the present invention', the device provides a method of counteracting to counteract the reaction force generated on the surface due to air flow.

444122 V. Description of the invention (15) In the illustrations 1 to 4 of the example, the elimination method is generated by the provided airflow generator and air inlet air inlet channel 60 to guide the airflow from the device to the surface 15 Air exhaust channel 70. The effect of cancellation in this state is described as follows: When the device is installed near the surface to be tested, the air discharged from the air outlet channel 70 and the force acting on this surface can be generated by the air entering the device through the inlet channel 60 Suction reaches practical equilibrium. This suction can be completed because in the example, the amount of air entering the suction port and the amount of air flow discharged through the discharge port establish a dynamic mass and flow balance in this device. Therefore, regarding this surface, When drained to the surface, the device can maintain a general equilibrium position. The use of the word "11 general balance" is because the system is dynamic and from a J practice point of view, the device is not expected to be absolutely stationary in the equilibrium state. The purpose of the reaction effect is to avoid the possibility of the device being driven away from the surface to be tested. Sex. When the device is suspended, the device is not allowed to be driven away from the surface to be tested. After being driven away, gravity will cause the device to vibrate and impact this surface, if it will cause damage to the device and the surface :. The following two conditions are acceptable. The first good condition is to achieve a dynamic force balance from the mass balance, so that the suspended device can maintain a general balance in front of the watch. In some environments, the second sinker can be accepted under certain conditions, that is, the suction force of the device is greater than the reaction force of the air flow on the surface. When air or liquid is directed towards the surface, the -1 device will be drawn back towards the surface and stay close to the surface. However, it is not recommended that the device be in contact with the surface to be tested, as such contact may ‘cause damage to this surface, such as on a smooth glass surface. '444122 V. Description of the invention (16) Dynamic flow equilibrium can be understood by the basic equations:

AoVo = AiV i where Ao represents the cross-sectional area of the air outlet (square meter)

Ai is the cross-sectional area of the air inlet (square meter)

Vo represents the speed of airflow leaving the air outlet (meters / square second), and Vi represents the speed of air entering the air inlet (meters / square second). The subscript 11 i "represents the state of the inlet, " represents the outlet In relation to the above-mentioned flow balance, the mass balance is defined as follows: pAoVo = pAiVi where p is the air density. In use, when the above mass balance can be achieved, the device can maintain a general balance of adjacent surfaces. The ultimate purpose is to confirm The circumferential force acting on the surface generated by the airflow generator will not cause the device to be driven away from the surface. According to the following equation, the pressure (P) changes with the speed (V): P = l / 2 pY2 Now, the force ( F) The general equation is:

Page 19 4441 2 2 V. Explanation of the invention (17)

F = AP Therefore, the outward force (F 0) acting on the discharge port can be calculated as: Fo = ΑοΡο Moreover, the weekly force acting inward of the suction port is calculated as:

Fi = AiPi is the difference in weekly force, and AF is calculated as follows: △ F = Fo-Fi = AoPo-AiPi △ F is a summary of the 杲 force, and all the calculated forces are acting on the device itself. The values of Pi, Po, and AF can be adjusted as the rotor speed and the size of the control hole opening described below change. In practice, when the general balance is reached, the device will not be driven away from the surface. AF is usually not 0, because the total force must consider other effects, such as the gravitational force acting on the device itself. However, when a general equilibrium state is reached, the general total force balance of all resulting forces will act within the system. • The inward force Fi and the outward force Fo are not determined to be generally balanced.

Page 20 444122

5. Description of the invention (18) As described above, 'In many cases, the loquat has a reaction force on the surface. In this example, when the inlet force is greater than the air flow acting on the surface, the device is placed or guided to the table or / and the liquid to direct the flow to the table. Because the pressure is proportional to the air flow 祙 銮 r up to 40 power. The cross-sectional area is determined by the installation speed (p). In the actual design of the special example, the shape of the part is determined. In the current flow generator ... the flow: t =: The equation that affects the escaping of gas > ^ This is just to provide instructions on how to calculate the device to reach the -㉟ equilibrium state. The special device uses two requirements, and it is necessary to perform experiments to obtain the power and size of the motor. In summary, when the condition of the air flow does reach the mass balance, when the liquid and the air flow are directed to the surface, the device can maintain the above general equilibrium position near the surface. It can be clearly seen in Fig. 4 that a certain amount of gas flowing out of the air discharge port channel 70 flows back to the device 10 through the air suction pipe 60. This repeated flow-back motion 'in the hollow space of the device is indicated by a dotted line in FIG. However, since the device 10 is not airtight in the atmosphere, part of the air entering the air suction inlet channel 60 is from the surrounding atmospheric air. Normally, the liquid flowing out of the mouth 20 cannot be metered into the device through the air suction port. However, if a special example is to be designed, some parameters are used to suck the liquid back into the device after it reaches the surface to be tested. The engine 40 must be waterproof. The position of the upper device 10 is placed close to the surface to be tested, and the device is used to simulate the same direction that guides liquid and airflow to this surface ~

Page 21 --- 444122 V. Description of the invention (19) side. Then there is a leak to confirm that in this example, the device flows out. This guides the device so that the air can establish a mass flat surface where the automatic surface is. When the surface enters the balance state at this inter-surface distance, the device The required distance from the degree of influence of the actual effect of the surface to be tested shall be stated as' sufficient suction body and airflow are guided on the surface. It is necessary for the horse to determine whether the amount of flow that can be placed in this table can reach a sufficient amount of airflow, and when the liquid surface can be maintained. The experimental results show that when the device is sucked onto the surface, it is close to the other side to be measured. The air drawn from the device and the air current are generally balanced up to 40 and the device is 10 off. Or, if you want to test the meter, this device can check the water required level. The installation example is specially designed to be selected for testing, such as surface, because it can be placed next to or windy. It is true that the surface of the self-loading device is set to increase the static pressure when the liquid is near the surface of the suction surface 15. The calculation formula is the difference in force, AF, as above AF = F0-Fi = AoP〇-AiPi This program calculates the dynamic pressure of air in a sports towel. However, the fire # ^ can further include the static calendar power Ps tat ic inside the device and the large rolling pressure patmos outside the device, and correct the calculation.

Page 22 444122 Five 'invention description (20) AF = Ao (Po + Pstatic) -Ai (Pi-Pstatic)-(Ao + Ai) Patm〇s Static pressure' P static 'As in this example, in a closed system Medium is a negative value, which means that this value is less than the atmospheric pressure Patmos. Therefore, the AF value is reduced, and the effect of static pressure is smaller than that of larger air pressure. In this way, the suction force pulls the device toward the surface. This is how the effect of internal static pressure on suction force changes. When the total resulting force △ F acting on the device is determined by the static pressure Pstatic and the atmospheric pressure Patmos, the force Fo acting on the surface by the airflow is determined only by the static dust Pstatic. Static pressure, Pstatic, can also affect the airflow force F0 acting on the surface, as shown below: F〇 = Ao (PIPIPstatic) When the maximum value F〇 is desired, in other words, the oxygen flow is applied with the maximum force One way to increase this force on the surface 15 is to increase the static pressure Pst at ic in the device. As in the current example, in a closed system, the static pressure is initially a negative value, meaning less than atmospheric pressure. Therefore, the static pressure, Pstatic, will increase with the opening of the hole or increase in size, approaching the atmospheric pressure outside the device. The opening of the hole will cause internal static pressure,

Pstatic, increase. An increase in static pressure and Pstatic 'will also cause an increase in the work force, Fo, acting on the surface. Using the above principles, the device of the present example provides a means of increasing the static pressure within the device.

• 444122 V. Description of the invention (21) ''-Method "The method of adding is to complete the form of a hole in the surface of the device. This hole, the air in the air inlet or / and the outlet and the large pressure outside the device /; IL pass. In Figure 2, the hole or opening on the device surface is 100 to the atmosphere. 'When the hole is opened in the crack, the static pressure Pstatic can be increased. Therefore, by increasing or opening the hole, it causes internal static. The pressure, Pst at ic, can be added to the surface and the force acting on the surface can be added privately. The device 10 has a mechanism for adjusting the size of the hole, so the static pressure and air force can be changed. Adjusting the size of the hole嚷 The user can adjust the amount of force acting on the surface, Fo ,. Due to the static pressure 'Pst at ic, it can only be increased to the atmospheric pressure, Patmos, the degree of adjustment of the force' relative to the surface 'acting on the surface, It can not affect the overall position balance or state of the device. Features that rely on internal static pressure changes cannot be applied to non-closed system inventions. Example 0 Further example illustration Figure 5 shows the change of the example of Figures 1 to 4 'shows further examples Description. This illustrative example includes a barrier device in the shape of 90 surrounding the barrier ring. In Figure 5, the ring is illustrated in a plate cut-out. The barrier ring includes two concentric rings 95A and 95B. The descending ring is generally placed around the airflow from the air. The discharge port channel 70 is expected to flow through the area of the air inlet 1 into the air suction port channel. This blocking ring receives the incoming air and discharges a part of this air from the small channel 97 in the device.

Page 24 444122

V. Description of the invention (22) Usually the air in and out is re-directed, because there is a channel 97 to block the inside of the device, so the effect has been discussed above. When the air interface is gone, the barrier ring will be created here. The spacer ring is open to the atmosphere. The effect of approaching the atmosphere is that the effect of air flow on the surface is from a narrow area to the area. . Therefore, internal static pressure is also caused, and the PStatie force is also increased. This effect is illustrated in FIG. 6 by another example. The method of elimination is to generate a secondary gas in a secondary air current generator that cancels the reaction force of the main motor 40. ^ ^

This time the airflow generator is like 40 A secondary motor. When the device of Fig. 6 is placed on a test surface of 1 kg ^, the reaction force to the air generated by the motor 40 on this surface = a strong reaction force, which can achieve the actual balance with the "inhalation force" of the airflow generated by the secondary motor 40A. The liquid and air flowing out of the duct 30 can be drawn to this surface at the same time. In this example of a non-closed system type, a level guide can be used to establish the position balance of the device adjacent to the surface to be tested, and the mass level is flat. Does not exist. The device of the present invention finds a special but non-exclusive application when testing the rain characteristics of a building structure or the surface of a building. When the device is used in a standardized test, the airflow rate parameter and the liquid outflow ¥疋 Can be standardized. It is hoped that the device user will not always require the device to automatically maintain a general balance. This is indeed a work to be done, only to satisfy the device of the invention. The user must be handheld or can be placed firmly on the stand. Above, and depending on the needs of the person, it is only necessary to spray the liquid and direct the airflow to the surface. Although it is impermeable, for example, for buildings and houses, and It is required to be an absolute vacuum, for example of the present invention to be not high wind and rain

Page 25 444122 V. Description of the invention (23) --- Infiltration process, the impermeable surface has been described. The degree of impermeability should be determined by the builder, architect or other designer. The examples of the present invention are intended to be used to test whether a structure can block wind and rain, such as a sunroof. The sky must prevent the rain from coming out ’, but the ability to block the wind will not be as good as a hunted window. The degree of imperviousness of the sunroof shall be the degree to which the manufacturer has set up resistance to wind and rain. From this point of view, the examples of the present invention may be applied to test the resistance of the structure to wind and rain. Other Examples The other examples are shown in Figures 7 and 8. This example has two characteristics: the device simulates an environment where wind and rain occur simultaneously. This device uses a blower 2000 as an air flow generator, and the blower 2000 is connected to an air exhaust port made of a duct 2o. The opening of this duct 21 has a certain length, but it is narrow. A certain length of duct can confirm that when the liquid flows out of the duct, a wide area is sprayed. However, the narrowness of the duct width can ensure that the sprayed liquid can maintain the pressure. With the degree of rate. The outer part of this duct 21 0 is a narrow and elongated slit structure from beginning to end. In the imagination, although this example can make more than one slit ', this reality has only one slit. The airflow can be directed from the blower out of the duct 210 using a curved hose 2 2 0. The duct 210 is provided with a liquid discharge port of the type of a spray hole 230. Nozzles 2 3 0 can be connected to the source of the liquid, such as tapping or pressing water (not shown here). The nozzle holes 230 and the blower 220 of this example can simultaneously guide the liquid and air flow to the same side of the surface to test the water-proof and wind-proof properties of the surface. The advantage of this example is that it is relatively cheap to manufacture and easy to transport-

Page 26 444122 V. Description of Invention (24) Although the device of this example can also be suspended, as shown in Fig. 8, this example can also use a stand 2 4 0. It must be noted that standoffs may be used for other examples when appropriate. The stand preferably includes another additional system to support the stand, such as an outer stand, a flat floor, or other flats or brackets. The mounting system, for example, should include brackets, struts, or ferrules. The shape and structure of this mounting system is determined by the characteristics of the outer bracket. Therefore, the point of view of this example is not limited to a configuration of a form or a special installation form. This alternative is particularly useful when not moving, but not when the unit is installed, such as a removable flat outer bracket, and transported to the required location. This example is improved by way of example only, and the possible modifications are within the scope and spirit of the invention, and its definition is as follows in the scope of additional patents.
