Title: Large-sized exterior awning device for high-rise building

Description:
TECHNICAL FIELD 
     The present invention relates to a large-sized external awning system for a high-rise building, which is configured to improve the effect of blocking solar heat, while being installed in the outside of a building to effectively block the sunlight (heat) from entering inside of the building, where the system is applicable for large scale high-rise buildings. 
     BACKGROUND 
     As the urbanization progresses, a design of the building has also changed in a way to alleviate a visual closure of the building. In addition, as a method for constructing a building more quickly, the use ratio of glass materials is increasing as an open and economical construction method rather than a typical closed-material form. Furthermore, a large-sized glass building having a curtain wall type in which a front exterior wall is made of glass becomes popular. 
     However, a problem for the energy efficiency of the building due to energy leakage, which is a disadvantage of the glass materials, has become a serious social and economic problem. Especially, the increase of the internal temperature of the glass building due to excessively direct sunlight in summer dramatically increases the cost of air-conditioning of the building, and is the main cause of power overloading of the whole country in summer. In addition, the excessive inflow of ultraviolet rays causes many problems in human health, and visual disturbance due to direct sunlight reflection in the glass building is emerging as a serious problem of urban pollution. 
     Conventionally, in order to block the inflow of solar heat, an approach for providing an awning inside of the building such as using curtains or blinds inside of the buildings, or attaching a color (shading) film to the glass is used. In recent years, it is being tried to employ low energy glasses or to insert ultra-small blinds between double/triple windows. 
     However, regardless of a type of internal awning method, the solar heat is already entered the inside of the building, and most of the solar heat energy stays inside of the building so the heat blocking effect is insignificant in a blind/curtain manner. In addition, the low energy glass and the like adopt the principle of the time delay of solar heat transfer, and thus, the solar heat blocking effect due to the awning is not great, and also, there is a disadvantage that installation cost is high. 
     In addition, there is a manner of installing an external blind or an awning, or a louver for the manner of providing an awning structure outside the building. However, there is a problem that the installation is limited due to the influence of the wind in the buildings of five stories or more, and there are problems of a cost and damage (change) to the exterior wall of the building permanently once installed. In particular, the louver costs more, and has to be installed permanently on the exterior wall of the building so there are many difficulties in securing the view and changing the appearance of the building, thereby being adopted restrictively. 
     DISCLOSURE 
     Technical Problem 
     The present invention is an innovative improvement of non-economic feasibility and the limitation of the installation in an existing manner for an external awning system in which the solar heat blocking effect in summer is higher (than the internal awning system), and the objects of the present invention are as follows. 
     First, it is an object of the present invention to provide a large-sized external awning system for a high-rise building, which can be provided in the large-sized high-rise building (for commercial, residential) largely affected by the wind. 
     Second, it is another object of the present invention to provide a large-sized external awning system for the high-rise building, which can be installed and removed as needed and does not affect the appearance of the building. 
     Third, it is another object of the present invention to provide a large-sized external awning system for the high-rise building, which can reduce the heating energy by allowing sunlight to flow inside to the maximum in the winter. 
     Fourth, it is another object of the present invention to provide a large-sized external awning system for the high-rise building, which can be used universally in economical installation cost.

     The present invention comprises: a winch  100  provided at an upper story, a rooftop or the ground of a high-rise building, and releasing or winding up a cable  110 ; two guide wires  200  connected to a lower story or the ground of the high-rise building from the upper story or the rooftop of the high-rise building, and spaced apart at a predetermined distance to be provided in parallel; a plurality of raising and lowering rods  300  provided in the horizontal direction, and provided with, at each of the left and right end portions thereof, wire-passing holes  310  through which the guide wires  200  pass such that the raising and lowering rods are raised and lowered along the guide wires  200 ; and an awning  400  coupled to the raising and lowering rods  300 , and unfolded so as to block the sunlight when the raising and lowering rods  300  are spaced apart from each other while being raised or lowered, wherein the cable  110  of the winch  100  winds up or release the uppermost or lowermost raising and lowering rod  300  among the raising and lowering rods  300 , and when the cable  110  of the winch  100  winds up the lowermost raising and lowering rod  300  among the raising and lowering rods  300 , the uppermost raising and lowering rod  300  is fixed to the guide wire  200  at the upper story of the high-rise building. 
     Advantageous Effects 
     Technical effects according to the present invention are as follows. 
     First, an external awning system can be provided in a high-rise large building (for commercial, residential), which has been virtually impossible due to the influence of the wind. 
     Second, the system can be provided without permanently and largely affecting the original appearance of the building and the overall city aesthetic. 
     Third, the glare pollution of the city center can be eliminated due to the direct light reflection of the glass building in a broad day. 
     Fourth, depending on the material of an awning, the system can not only take into consideration some views at the same time as an awning, but also be used for the screen by the beam project at night. 
     Fifth, easy control and management of the entire system can improve the efficiency of building energy management, and saving energy costs alone can get investment costs for the awning back early. 
     Sixth, the system can allow for various designs to be used to create fresh city scenery in summer, and company logos and pitches can be attached to the awning for public promotion.

     BEST MODE 
     Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 
     The present invention relates to a large-sized external awning system for a high-rise building, and particularly, a large-sized awning system which can maximize the awning effect by being provided in the outside of a building and blocking the sunlight (heat) from entering inside of the building in summer, and also is capable of applying to a high-rise large-sized building. 
     A winch  100  is provided on an upper story, a rooftop or a ground of a high-rise building and serves to release or wind up a cable  110 . 
     The winch  100  corresponds to a kind of cable reel, and it can be selected among various kinds and specifications of products in consideration of conditions such as installation space, a surrounding environment or the like. 
     The winch  100  may be provided on the ground as shown in  FIG. 1 , and may be provided on the rooftop of the high-rise building as shown in  FIG. 2 . Although not shown in the accompanying drawings, it is also possible to provide a suitable installation space in the upper story of the high-rise building and install the winch  100 . 
     Guide wires  200  is connected to a lower story or the ground of the high-rise building from the upper story or the rooftop of the high-rise building, and two guide wires  200  are provided spaced apart at a predetermined distance to be provided in parallel and serves as a guide for raising and lowering rods  300 . The guide wires  200  also serves to fix an unfolded awning  400  immobile from the effect of the wind. 
     The raising and lowering rods  300  are provided in the horizontal direction, and provided with, at each of the left and right end portions of the raising and lowering rods  300 , wire-passing holes  310  through which the guide wires  200  pass such that the raising and lowering rods are raised and lowered along the guide wires  200 . 
     The number of the raising and lowering rods  300  can be appropriately determined in consideration of a size and a height of the building. 
     The cable  110  of the winch  100  can be connected to the uppermost or lowermost raising and lowering rod  300  among the raising and lowering rods  300 , wherein when the winch  100  is provided on the ground as shown in  FIG. 1 , the cable  110  is connected to the uppermost raising and lowering rod  300 , and when the winch  100  is provided on the rooftop of the high-rise building as shown in  FIG. 2 , the cable  110  is connected to the lowermost raising and lowering rod  300 . Here, when the cable  110  is connected to the lowermost raising and lowering rod  300 , of course, the uppermost raising and lowering rod  300  must be fixed to the guide wires  200  at the upper story of the building as shown in  FIG. 2  and should not move along the guide wires  200 . This is because when the uppermost raising and lowering rod  300  lowers along the guide wires  200 , the awning  400  cannot be unfolded as shown in  FIG. 2 . 
     In other words, in  FIG. 1 , the awning  400  is unfolded while the raising and lowering rods  300  rises, and in  FIG. 2 , the awning  400  is unfolded while the raising and lowering rods  300  lowers. 
     With the awning  400  unfolded, a distance between the raising and lowering rods  300  can be designed to be approximately 1 meter to 3 meters. 
     The awning  400  is coupled to the raising and lowering rods  300 , and unfolded so as to block the sunlight when the raising and lowering rods  300  are spaced apart from each other while being raised or lowered. 
     A guide pulley  120  serves to guide raising and lowering of the cable  110  while being rotated by engaging with the cable  110  which is released from or wound up to the winch  100 . The cable  110  can be raised or lowered stably along a predetermined path by the guide pulley  120 . 
       FIG. 3  shows a specific embodiment of the awning  400 , wherein the upper and lower portions of the awning  400  are attached to the raising and lowering rods  300 , respectively, and the awning  400  is unfolded sequentially as the raising and lowering rods  300  rise or lower, and a distance between the raising and lowering rods  300  is determined by a distance between the upper portion and the lower portion of the awning  400 . 
     Materials of the awning  400  can be selected from various materials, such as general tent materials, translucent netting materials considering a view, natural materials and so on. It is preferable to select a material which can suppress damage or aging caused by sunlight or rainwater etc. to the utmost and has a sufficient strength and durability. 
       FIG. 4  shows another embodiment of the awning  400 , wherein only the upper portion of the awning  400  is attached to the raising and lowering rods  300  and the awning is unfolded sequentially in a suspended state, and a weight member  410  is attached to the lower portion of each awning  400  to weight the awnings  400  and keep it unfolded. In other words, one raising and lowering rod  300  is attached to one awning  400 , and each awning  400  keeps a naturally unfolded state without fluttering due to a weight of the weight member  410 . 
     The weight members  410  can be made of a variety of materials, and its shape and structure are not particularly limited. The weight members are attached to the lower ends of the awnings  400  and prevent the awnings  400  from fluttering due to a proper weight. 
     In addition, connecting cables  320  interconnect the raising and lowering rods  300  to determine a distance between the raising and lowering rods  300  when the distance between the raising and lowering rods  300  increases as the raising and lowering rods  300  ascend or descend. 
       FIGS. 5 and 6  show another specific embodiment of the awning  400 . 
     A panel frame  420  is composed of two panels coupled by hinges  440  to rotate and move. Blind portions  430  are provided at central incision portions of the panel frame  420  so as to block the sunlight and see the outside. 
     The blind portions  430  can be a blind made of bamboos, palm leaves, reeds, or fabrics. The blind portions can effectively prevent the sunlight from entering and make it possible to see the outside through a gap of the blind, thereby providing blocking the sunlight and seeing the outside at the same time. 
     An upper portion of an upper panel of the panel frame  420  is coupled to a lower portion of a lower panel of a neighboring panel frame  420  by the hinges  440  to rotate and move at the raising and lowering rod  300  located at the upper portion of the upper panel. A lower portion of a lower panel of the panel frame  420  is coupled to an upper portion of an upper panel of a neighboring panel frame  420  by the hinges  440  to rotate and move at the raising and lowering rod  300  located at the lower portion of the lower panel. 
     The panel frames  420  are also overlapped or unfolded by the cable  110  of the winch  100 .  FIG. 6  shows a case where the panel frames  420  constituting the awning  400  are overlapped and received on a panel holder  450  when the panel holder  450  is raised by the cable  110 . In other words, the cable  110  is not directly connected to the raising and lowering rods  300  but is connected to the panel holder  450  as shown in  FIG. 6 . Also in this case, of course, the uppermost raising and lowering rod  300  should be fixed to the guide wires  200  at the upper story of the building as shown in  FIG. 6  and should not move along the guide wires  200 . This is because when the uppermost raising and lowering rod  300  descends along the guide wires  200 , the awning  400  cannot keep an unfolded state. 
     The panel holder  450  is provided at a bottom of the lowermost raising and lowering rod  300 , provided with, on both sides thereof, rings  460  through which the guide wires  200  passes, and is connected to the cable  110  of the winch  100  to ascend and descend. 
     A sensor  510  detects a length of the cable  110  that is released from or wound up to the winch  100 , and various types of sensors can be selected. In some cases, a sensor that senses the number of revolutions of the guide pulley  120  and calculates a distance of the cable  110  passing through the guide pulley  120  may be used. 
     A controller  520  receives a sensing signal from the sensor  510  or receives an input signal instructing an operation of the winch  100  to control the operation of the winch  100 . When a plurality of winches  100  is provided in one building, it is also possible for the controller to integrate and control them. 
     A housing  600  is provided on the upper story, the rooftop, or the ground of the high-rise building, and serves as a receptacle for accommodating the awning  400  when being folded. The housing  600  is generally provided in the same location as the winch  100 . 
     Although specific embodiments of the present invention have been described with reference to the accompanying drawings as above, it is to be understood that the scope of protection of the present invention is not necessarily limited to such embodiments, but various design modifications, additions and deletions of known techniques, simple numerical limitations etc. within the scope which does not change the teaching of the invention are included in the scope of protection of the present invention.
