Description

TECHNICAL FIELD The present invention relates to a repetitively operating and labor-free snow unloading apparatus that uses a compressed air jack force of an air bag and a snow sliding sheet to remove snow on a sloped roof, thereby reducing snow.

Northern Japan and heavy snowfall areas along the coast of the Sea of Japan have snowfalls every winter, and recently, record snowfall has occurred due to heavy snowfall in extreme weather. Especially in places along the coast of the Sea of Japan where heavy wet snow continues to be exposed, it is exposed to the risk of collapse of buildings, etc. due to unexpected snow, especially the care of the roof snow of private houses is an individual responsibility, and snow removal work is The current situation is that there is no choice but to snow down by human power. However, due to the peculiarities of working at high places and the danger of falling and injured, there are many victims such as falling deaths and falling snow injuries in sudden snowfall years.

However, as the mechanization of snow treatment on the ground has progressed remarkably, there is still no appropriate roof snow countermeasures for existing houses, and the development and popularization of easy-to-implement measures are quite advanced even for snow drainage treatment at individual responsibility. There is no situation. Therefore, when the danger of collapsing comes, volunteers and other volunteers are supporting the snow removal work with desperate activities next to the risk of sliding down and death. It has been an urgent issue that must not be.

However, as a full-scale countermeasure, there are, of course, renovations and new construction cases. In the case of prior art inventions, as a method of lowering snow, the existing roof is largely remodeled to remove snow and a roller conveyor is used as the roof. Although the thing which applied the snow removal apparatus which does not rely on human power by constructing etc. is proposed (for example, refer patent document 1), all are large-scale and have a large expense burden.

The conventional roof snow removal devices and methods described above are inventions having appropriate characteristics, but all of them require a large amount of work and a large construction cost. If so, there is an option to remodel or build a new snow-resistant house. However, these are issues that cannot be implemented in leased houses, and there are construction issues that are difficult to deal with easily because there are complicated housing problems and structural problems of the houses. Expenditure alone is a heavy burden on the economy, and there is a problem that it is difficult to start with ordinary households. Therefore, it is difficult to deal with the snow covered by the snow every winter, and it is difficult to deal with it despite the heavy snow forecast. There is no point.

However, there are various problems faced by various solutions disclosed in the prior art. For example, various conditions such as the condition of the roof surface from which snow is removed and such costs are not uniform, and thus are generally suitable. It can be considered that various specification conditions are extremely limited. For example, even if you are aware of the danger, you cannot expect the situation of rebuilding or snow-resistant remodeling or a large cost burden, the situation where the building is not allowed to be modified (rental house), or a historically historic cultural building In some cases, too. In particular, this problem is not limited to residential houses, and has a significant impact on the livelihoods of agricultural and industrial companies, such as various laboratories, storage areas, livestock farm machinery storage sheds and livestock breeding sheds. There are also concerns about the fall of snow and damage to many structures related to full-time work, such as the danger of lodging of buildings with simple structures and the damage of lodging of many agricultural houses. However, for many years, the development of appropriate defensive measures and effective snow drainage techniques has not progressed.

From the viewpoint of cost burden, there is an expectation of a solution that can respond flexibly to large and small on-site scales and is cost effective and less burdensome. Therefore, if the disadvantages of the conventional prior art are listed, for example, 1 is large and the cost burden is high. 2. Management and snow removal treatment are difficult for amateurs. 3. A lot of manpower and costs are required to operate the snow. 4. Concerns that the structure will always remain erected in the summer. 5. There seems to be a fundamental problem that is difficult to implement, such as removal removal after installation is not easy.

The present invention is a problem that the conventional prior art has, such as large-scale construction, etc., not to make structural changes to the house, and to the various conditions of the roof of the target house, easy adjustment work to any scale Can be prepared in advance during the safe period in preparation for the arrival of snow, the equipment can be easily installed on the roof, and can be removed when it is not needed. There is no human climbing on the roof, yet it is safe with common sense knowledge, it is possible to perform snow draining operation on its own, and it is possible to slide down snow without effort with simple operations such as startup and adjustment operations, It is possible to handle snow removal operation as many times as possible during the snowy season, to be removed from the roof and stored in the snow-free season in spring, and to be reused in the next winter. Expenditure costs (replenishment of deteriorated parts) only need to be added, and the appearance of the construction is negligible and negative In consideration of improvement measures such as less feeling, construction of a system that can safely and effortlessly remove snow without going up to a roof that has never been thought of, and that can return to a restart system The purpose is to realize.

(1)
In order to achieve the above object, the present invention contemplates a mechanism in which snow piled up on a sloped roof begins with physical pressure by electric switch operation, gradually becomes unstable gravitationally, and automatically falls. Without climbing on the roof, according to the procedure, the sliding part is divided and dredged and operated, and the behavior of falling snow is predicted and adjusted while monitoring at a safe place on the ground, making it effortless and safe In addition, it is a mechanism that can remove snow by automatically sliding down the snow on the roof, and has an extremely advantageous feature that can be restarted, which was not conceived in the past, simple construction, excellent economic efficiency and on-site adaptability Was developed.
(2)
The mechanism is intended for houses with ordinary sloped roofs, and there are two patterns as described above for both single-story sloped roofs and two-story one-story one-sided sloped roofs. The object is assumed to be a common snow removal device, and the material shape of each roof, for example, a roof shape such as a galvanized steel plate (tin) roof or various tiled roofs or thatched roofs is also assumed. Although each building has a difference in the degree of the slope of the roof slope, basically, the roof snow automatically slides by physical pressure initiated by ground electric operation while utilizing the slope of the roof A functional device with a restarting device that can safely and effortlessly remove snow and immediately recovers is devised. In addition, even a flat roof with a small inclination can be theoretically handled.
(3)
The configuration outline will be described below by item.
(Section 1)
A laying square that covers the entire target area (range) on the target roof with a sheet (hereinafter referred to as “base sheet”) that serves as a basis (base) for constructing the apparatus of the present invention. Thick sheet.
(Section 2)
Two types of inflatable pressure-resistant functional airbags (note, utilizing the inflating air jack force) are devices that are installed on the seat of the first item and exhibit the starting force of snow removal.
(Section 3)
In order to protect and maintain the functions of the first and second items, a sheet having a cover and snow-sliding function that covers and covers the entire laying object, has both weather resistance and waterproofing, and a sliding-inducing function on the surface ( Note, in the following, referred to as “cover sheet”). The same dark color system as general roofing materials is desirable.
(Section 4)
Regarding the two types of airbags mentioned in the above (1st and 3rd paragraphs) and the two types of airbags in 2nd paragraph, (a) related equipment for the entire mechanism and (b), its operation and operation .
There are four parts as described above.

Furthermore, there is a peculiarity in the light and economical functional system that actively uses the functions of the popular self-compressor and small household vacuum cleaner, and it is easy to lay the equipment by the material structure that can be changed according to the site scale. Temporary construction that is easy to handle during the snowy season, and to install and remove during the dead season. This is an excellent function that can remove snow without any labor and repeated snow removal by simply operating the electric switch from the ground, and can push snow from the bottom. The gravity of the snow fluctuates due to the dynamic pressure and the pulling movement of the sheet surface, and the applied pressure is such that the snow slides naturally. Safely as intended One in which was devised by dividing can be structured. Basically, it uses the slope of the roof, but even though the function of the device is a flat roof, there is a unique feature in the system that can theoretically handle it.
Hereinafter, the mechanism will be described by item. Reference numeral 1 is a “base” base sheet for constructing the apparatus of the present invention, and is a rectangular thick sheet laid on the entire target range on the target roof. Reference numeral 2 (and 6) is a device of the present invention which is placed on the seat of reference numeral 1 and is left standing. There are two types (details will be described later) of the air bag made of a sheet having a pressure-resistant bag structure that greatly expands air. It is a bag, and an expansion force due to a compressed pneumatic force to be injected becomes a driving force. Reference numeral 3 is a sheet that covers and covers the entire laid structure of the above-mentioned reference numerals 1 and 2 (and 6), and is a weatherproof waterproof performance and a cover sheet that is processed to induce sliding down on the surface (reference numeral 3). Due to the systematic construction of the three parts and associated equipment, the entire device to be knitted becomes the structure of the present invention of claim 1.
The structure and mechanism of the structure of the invention will be described below.
The material and material characteristics of the custom-made base sheet of the above-mentioned reference 1 are intended to be spread over the intended area for snow removal purposes on the roof (note, effectively functioning, one-sided square) It is a square sheet (reference numeral 1), in order to prevent damage caused by protrusions on the roof, and an air bag (notes, reference numerals 2 and 6 to be described later in detail) installed on the upper surface of the base sheet is pressurized and expanded. In order to prevent occasional rupture damage, such as freezing due to flooding or adhesion, it is necessary to prevent adhesion, etc., and the inner core (plate) is about 1 to 3 mm thick. However, it is desirable to use a material with high waterproof and water repellency from the viewpoint of application function. Especially, the contact with the fabric surface of the air bag placed on the roof is desirable. Due to the high temperature during sunshine, the fabric surface is altered and the fabric surface melts. Since it is feared, it is desirable to softening prevent chemical on the sheet material that Kotengu. In addition, in order to reduce the contact area, it is also a countermeasure to adopt a rough surface manufacturing method, that is, a satin specification, in which the surface of the cloth surface is processed.
Next, the procedure for laying the base sheet on the roof is cut to a size corresponding to the shape of the required roof surface at the site, laid on the entire slope (both sides) of the roof, and on each end of the base sheet surface. Using the processed eyelet, it is a construction that suspends and holds it at the part straddling the roof horse part, depending on the width of the roof surface, depending on the situation where snow can be removed and the intention to remove snow There is a functional feature that is advantageous in a configuration that can be divided and dealt with appropriately, such as partially limiting the width of the base sheet and shortening it vertically.
The following explanation of the structure of the air bag 2 (and 6) is a pressure-resistant air bag that injects and inflates the compressed air of the intended purpose. Nylon, aramid, polyester, etc. with strong pressure resistance, and the inner surface of the mesh surface made of twisted yarn with a thickness of about 1 to 3 mm was adhesively coated with a thin airtight film sheet or laminated synthetically. Using a high pressure pressure resistant base material that has been subjected to water proofing, a bag-shaped airbag (each of the two types is assumed to have an internal volume of 200 to 400 liters) is produced. As already shown in the prior art, there are examples of airbags that can lift the weight of several tons by the exhaust gas power of a car, and the structure can be expected to have a sufficient function depending on the bag material. Using the fabric base material having the above composition, a special strong pressure-resistant air bag specification that is sewn into a bag shape and joined with an adhesive chemical solution is manufactured. Schulf type) and two types of paper bag type (symbol 6, handbag type, smart bag type) that swell in the shape of sandbags were devised and formulated. And the two nozzles of the forced exhaust port (2 systems, 2 ports side-by-side), the end of the nozzle (nozzle diameter 6 mm inside diameter, outside diameter 9 mm, code 4) is inserted by cutting the body cloth surface, Two pressure-resistant hoses (each with an inner diameter of 6 mm and an outer diameter of 9 mm) are connected to a pressure-resistant air hose and used for extended operation up to the ground. Installation is an air bag body cloth with an opening and a vinyl disc shape The specifications of the nozzle part (metal inner diameter 6 mm, outer diameter 9 mm supply, exhaust two-hole connection part) with a pressure-resistant durability structure that uses soft cushioning material (Ella) and is durable with repeated use. ((A) and (B) in FIG. 4). It is desirable that the instrument configuration be as short as possible so as not to impede the operation and behavior of the airbag in terms of function. The details of the instrument structure are for injection (reference numeral 9 in FIG. 4) with a check valve. This is a specification with two nozzles for porous forced exhaust (symbol 10), and a pressure-resistant air hose with a single length (feed and exhaust 2 systems) that can reach this instrument and the instrument panel on the ground. Using a dedicated connecting device (coupler plug, coupler socket model of numerals 17, 18, and 19) that connects the code 7, a commercial product, adopting an inner diameter of 6 mm and an outer diameter of 9 mm), an extended pressure-resistant air hose (spiral hose, code 19) The functional operation of the present invention is ensured by the specification of the extended connection.
Next, the reason for the two types of airbags is that 1 is the highest point of the roof, the shape that locally protrudes at the tip, is intended to be a jack force effect that expands into a true circle and gains height, It is intended to deal with heavy and frozen snow masses that hang down from the bottom of the roof, freeze and set widely, and is strong and heavy, and is intended to support weight distribution. Considering the size (the size of the internal volume) and the required number of laying, it is desirable to correspond with the number of sets (explained in FIG. 3), and the airbag is attached to the inner surface of the cover sheet at the lower end portion of the roof. In a flat (vacuum state), the construction work is carried out in a state where it is placed and suspended in a single sheet, and is fixed to and held on a fixing fastener on the upper surface of the underlying base sheet.
Next, the cover sheet of reference numeral 3 uses a synthetic resin sheet such as a thick (2 to 3 mm) vinyl chloride that has a function of covering the entire apparatus on the roof and a surface treatment on which the snow slides down. It is made of a material that can prevent the penetration and backflow of snowmelt water, but it must be covered with a length that reaches the highest position of the back of the building eaves (overhang) and stored together with the attached air hose etc. In order to prevent wind from entering the cover sheet, it should be tightened and tightly secured to ensure that it is always in place during the snowy season.
The following 4 items are related to the equipment in (a): the nozzle part of the air bag (supply / discharge port part, two lines in parallel) and the two nozzles for forced exhaust. Equipment with an inner diameter of 6 mm and an outer diameter of 9 mm (reference numeral 4, for the injection nozzle, reference numeral 13 is an air check valve, and reference numeral 14 is a perforated pipe specification "for prevention of clogging" for forced exhaustion) A pressure-resistant hose (with an inner diameter of 6 mm and an outer diameter of 9 mm) is connected to the instrument panel on the ground, and the instrument panel has an air inlet device. In addition, the exhaust nozzle (bore size, inner diameter 6 mm, outer diameter 9 mm, code 20) has a manual air cock valve (can be switched between open and closed during air supply and exhaust) when starting a normal snow discharge system Confirms the safety of the site, monitors the behavior of snow on the roof, operates the air compressor, enables air injection operation, and judges the situation sufficiently so that there is no excessive air injection. However, the snow can be cleared by adapting to the circumstances. Furthermore, there is a configuration in which it is desirable to equip and organize an overpressure alarm device, an overpressure automatic opening valve device, etc. for monitoring the pressure applied and safety.
Regarding the operation of the present invention in item 4 (b) of the next explanation item, when the winter snowfall progresses and the snowfall on the roof needs to be removed, the cover sheet is pulled out at the appropriate time. Open the leash (reserve the leash), place the cover sheet in a free state that allows easy deployment of the cover sheet accompanying the expansion of the internal air bag, start the electric (or engine type) air compressor, and When the compressed air is injected and the air bag (with check valve) inflates, the cover sheet gradually lifts with jacking force, pushes up the snow mass, and the roof snow naturally slides on the cover sheet of the sloped roof At this time, in particular, it is important that the compressed air injection sequence starts from the air bag in the lower part of the roof and then shifts to the upper stage in succession. Can be expected and linked In because it is assumed that the fall in the avalanche phenomenon, such as the safety zone space confirmation and the snow-expelling fall accident prevention fence on the ground of falling location, it is necessary to put in sufficient consideration of the safety measures.
After the snow removal on the roof is completed, the next is the air cleaner (electric vacuum cleaner) suction port on the ground and the ground for the return that can be restarted by sucking and exhausting the residual air in the air bag on the roof Connect the exhaust nozzle of the instrument panel with a special joint device (connecting hose (caliber inner diameter 6 mm, outer diameter 9 mm), symbol 22, symbol 17, symbol 18). Is removed by suction (described with reference to FIG. 7). After the exhaust is completed, the cover sheet can be returned to the original state by inspecting the tension of the cover sheet and retightening, and can be returned to the standby state for the snow discharge operation.
With the above operation, it is not necessary to go up to the roof for snow removal, it is possible to repeat the operation (work) of snow removal as many times as possible, the work can be removed safely and effortlessly, many workers This is a work suitable for the shape of the snow removal object, and can be appropriately dealt with on a desired scale without limitation, and it is preferable that measures can be taken easily. With a functional structure based on an unprecedented idea, it has a superiority, and it uses light electrical equipment such as general-purpose household vacuum cleaners and air compressors (organizations that can mobilize engine generators, inverter equipment, etc.). It is characterized by an energy-saving, economical, and simple structure that rationally utilizes the laws of nature, such as a flexible air bag function and a snow sliding sheet function that naturally slides down (cover sheet). Pre-laying in preparation for snow cover (temporary Possible, there is a feature where the corresponding erection device Linsen, a snow removal device pitched roof snow with a number of dominant features described above.
(Note: For convenience of explanation, the two sheets of the base sheet of reference numeral 1 and the cover sheet of reference numeral 3 have been described separately. However, these two sheets are one continuous sheet and are V-shaped at the top of the roof. (The reason is to prevent the intrusion of snowmelt water from the top of the two sheets in the two sheets.)

The action of the problem solving means is a combination of an airbag (expansion force) and a sliding sheet (cover sheet). By turning on an electric switch, it is possible to safely and effortlessly and naturally fall down by systematic, effortless and safe. Yes, claim 1 has a return system that can be restarted, and the snow removal work on the roof can be repeated easily and repeatedly by itself, and it can be expected to have an unprecedented effect. It can be laid down and removed during the snow-free period, and can be reused in the next period.

As described above, the snow removal device for roof snow according to the present invention is constructed based on an unprecedented idea, and the advantages and advantages of the snow removal means for gradient roof snow are as follows. Constructed material, laying method and operation method are easy, simple construction method suitable for the actual situation, cost burden can be adjusted depending on the site, timely and accurate snow removal is possible, labor-saving effect, safe and efficient With the effort, it is possible to provide a snow removal system device in which snow falls automatically.

The present invention is a jack that expands by injecting compressed air into an air bag (reference numerals 2 and 6) installed in a sheet (appendix 1 and reference numeral 3) laid on the roof for snow removal treatment on a sloped roof. A three-part device that uses an up force as a starting source and a cover sheet (symbol 3) that is designed to create a smooth floor that snow is automatically slid according to the laws of nature. From the re-functional specification that can return to the original negative pressure state by removing the forced suction, snow removal of the multifunctional roof that has never been before, equipped with a function that can be repeated many times without effort, without climbing the roof Concerning equipment, the construction of equipment that can be adapted to the scale of the site, has specificity in a light and economical functional system that actively uses the functions of the popular simple compressors and small household vacuum cleaners Being able to handle, easy on a scale Easy to use and maintain, easy to handle snow removal and common sense, and features a temporary construction that is easy to lay and remove during the snowy season and when it is not in use. This is an excellent function that makes it possible to repeatedly remove snow, with no effort, by simply operating an electric switch from the ground, and with the physical pressure that pushes the snow from the bottom and the pulling action of the cloth surface. As a result of this, the pressure applied to the natural slide by itself is added, and in addition to the effect of the cloth work that becomes a slide, a gravitational phase of falling snow is created at once, and a mechanism that can safely remove snow cover as intended is devised. Basically, the slope of the roof is used, but even if the function of the device is a flat roof, there is a characteristic that is unique to a system that can theoretically handle it. 1, “Construction of the device of the present invention” The “foundation” sheet (hereinafter referred to as “base sheet”) is a rectangular sheet laid on the entire target area on the target roof, and reference numerals 2 (and 6) denote the reference numeral 1 sheet. The air bag device of the present invention to be placed on top of the seat. The air bag device of the present invention has two types (details will be described later), is a pressure bag structure with a large air expansion, and is an air bag made of a sheet. Is the driving force. For reference numeral 3, it is a cover sheet (reference numeral 3) that covers the entire construction of the construction of reference numerals 1, 2 (and 6), and has weatherproofing waterproof performance and processing that induces sliding on the surface. The entire apparatus knitted by the above three-part systematic construction is the structure of the present invention of claim 1. In addition, there are (b) equipment connection-related equipment and (b) equipment maintenance required for the function activation intended by the present invention described above, and the overall description is the above items 1 to 3 ( 3 parts, reference numerals 1 to 3, and the fourth term (A) and (B).

The structure and mechanism of the structure of the invention will be described below. The material and the material characteristics of the custom-made base sheet of the above-mentioned reference number 1 are the intended area for snow removal on the roof (note, effective Is a rectangular sheet (reference numeral 1) for the purpose of spreading on a single-sided square, which prevents damage caused by protrusions on the roof, and an air bag installed on the upper surface of the base sheet ( Notes 2 and 6), which will be described in detail later, cause rupture damage during pressurized expansion. For example, the thickness is about 2 to 3 mm in order to prevent freezing or adhesion due to flooding. However, it uses a waterproof fiber fabric with a synthetic resin sheet such as multi-layer vinyl chloride, which has an inner core (plate), but it is desirable to use a material with high waterproof and water repellency for its application function. In particular, with the fabric surface of the airbag It is desirable to use a sheet material coated with a softening-preventive chemical because the touch is altered due to the high temperature of the roof during sunshine, and the fabric surface may be fused. To reduce the contact area, etc. Also, we would like to adopt a rough surface production method, that is, a pear-skin (nashiji) specification. Next, the base sheet to be constructed on the roof is cut to a size corresponding to the shape of the required roof surface of the site to be snow-removed, laid on the entire surface of the roof (both sides), and the base Using the eyelet holes machined at each end of the seat surface, the construction that suspends and holds the parts that straddle the roof horse part is possible, and the snow can be drained according to the width of the roof surface. Depending on the intention of snow removal or the intention of snow removal, there is a functional feature that is advantageous in a configuration that can be divided and dealt with appropriately, such as partially limiting the width of the base sheet and shortening it vertically.

The structure of the air bag 2 (and 6) in the second item is described as a pressure-resistant air bag (note, 2 and 6) for inflating by injecting compressed air for the intended purpose. It is a system configuration designed to use the repulsive jacking force, and the inner surface of a strong twisted yarn netting of about 1-3 mm thick nylon, aramid, polyester, etc. Bag-like airbags (200 liters each with an internal volume scale of 2 types) using a high-pressure pressure-resistant material with water proofing, such as adhesive coating or laminating composite sheets. As shown in the prior art, there are examples of airbags that can lift the weight of several tons with the exhaust gas power of the car. , It is a structure that can be expected to have a special function, and by using the fabric base material of the above composition, each manufactures a special strong pressure-resistant airbag specification joined in a bag shape with an adhesive chemical solution, and the shape is cylindrical Two types of specifications were devised and developed: a sleeping bag type (symbol 2, shruff type) that inflates into a sandbag, and a bottomed paper bag type (symbol 6, handbag shape, smart bag type) that swells in a sandbag shape. Is attached with two nozzles (combined with 2 lines, 2 ports side by side) of the compressed air inlet and forced exhaust port (nozzle diameter 6 mm inner diameter 9 mm outer diameter, 4), and two air hoses Connecting the pressure-resistant air hose into a single unit, the nozzle part mounting above is provided with an opening in the air bag body and uses a vinyl disc-shaped soft cushioning material (Ella shape) for repeated use and durability Pressure-resistant durability formed on a flexible nozzle tube The specifications of the nozzle part (hard inner diameter 6 mm, outer diameter 9 mm supply, exhaust 2 port connection part), as much as possible so as not to impede the operation and behavior of the air bag functionally Although a short instrument configuration is desirable, the details of the instrument structure are the specifications with a double-equipped nozzle for injection (reference numeral 9 in FIG. 4) and a check valve for porous forced exhaust (reference numeral 10). In addition, this unit and a dedicated pressure hose (symbol 7, commercially available, inner diameter 6 mm, outer diameter 9 mm) that can reach the instrument panel on the ground are integrated. The function activation of the present invention is ensured by the specification of extending and connecting with an extension pressure-resistant air hose (spiral hose, reference numeral 19) using a connecting tool (coupler plug, coupler socket type of reference numerals 17, 18, 19). Next, the reason for the two types of airbags is 1 is ya At the highest point, the tip is locally protruding, intended to be a jack force effect that expands into a true circle and gains height, 2 hangs down at the lower end of the roof, freezes and freezes, hardened and heavy It is intended to deal with a frozen snow block and to support weight distribution, and is arranged considering the size of the air bag (internal volume) and the required number of layings, depending on the area of the roof where snow is to be removed. The set type of configuration (explained in FIG. 3) is appropriate and desirable, and the airbag is placed on the inner surface of the cover sheet at the lower end of the roof, and is placed in a flat (vacuum) sheet and suspended, The construction work is to be fixed and held on the fixing fastener on the upper surface of the base sheet.

Next, the cover sheet of reference numeral 3 is provided with a maintenance function that covers the entire apparatus such as reference numerals 1 and 2 laid on the roof and the connecting device, and a functional thick ( It is made of a synthetic resin sheet such as vinyl chloride (about 2 to 3 mm), and is made of a material that can prevent the infiltration and backflow of snowmelt water on the roof, but it is the highest in the back of the building (overhang) Cover with the length to reach the position, it is necessary to store it together with the attached pressure-resistant air hose etc., and store it in the attic, using the eyelet holes around the cover sheet so that the wind does not enter inside the cover sheet, It is tightened with a rope and secured completely, so that it can be placed on standby for snow drainage during the snow season.
(Note: For convenience of explanation, the two sheets of the base sheet of reference numeral 1 and the cover sheet of reference numeral 3 have been described separately. However, these two sheets are one continuous sheet and are V-shaped at the top of the roof. Since it is folded and laid, it is described as two upper and lower sheets from the functional aspect. * The reason is to prevent snow melt water from entering into the two sheets).

Next is the explanation of item (a) related to the equipment related to the connection of the equipment, but there are two nozzles for the air injection and the forced exhaust for the nozzle part (supply / exhaust part) of the airbag (reference numeral 4). In order to connect to the nozzle, there is an air check valve with a reference numeral 13 and a device with a porous pipe specification “for prevention of clogging” for forced exhaustion. The pressure hose (6 mm inside diameter and 9 mm outside diameter) is extended to the instrument panel on the ground, and the tip of the pressure hose (6 mm inside diameter and 9 mm outside diameter) on the instrument panel is used to supply and discharge air. The exhaust nozzle (symbol 20) has a manual air cock valve (used for switching when supplying air and exhausting). When a normal snow discharge system is started, the safety zone on the site , A function that allows air injection operation while monitoring the behavior of snow on the roof In addition, it is possible to judge the situation so that there is no excessive air injection, and to adjust the snow while removing the snow while responding to the circumstances. In addition, for overpressure monitoring and safety, an overpressure alarm device and overpressure In some configurations, equipment and organization such as an automatic opening valve device is desirable.
The next explanation item is (b) related to the operation of the device. When winter snowfall progresses and when it is necessary to remove snow on the roof, the cover sheet (symbol 3) should be pulled out. Opened (reserved securing rope), placed in a free state, easy to freely deploy cover sheet behavior associated with expansion of the internal air bag (reference 2 and reference 6), electric (or engine type) air compressor When the air bag (with check valve) is inflated by injecting the specified compressed air, the cover sheet (symbol 3) is gradually lifted by jacking force and pushes up the snow mass, and the roof snow covers the gradient roof The sheet (symbol 3) will naturally slide down. At this time, in particular, the compressed air injection sequence starts from the airbag (symbol 6) in the lower part of the roof and is sequentially performed in the upper stage. Is important. It can be expected that snow slides on the top of the roof will slide down, and it is assumed that the snowfall will fall at once, so safety measures such as checking the safety zone space of the falling place on the ground and the snow fall fall prevention fence are sufficient It is necessary to put it in consideration. Next, when the snow removal on the roof is completed, the air cleaner (electric vacuum cleaner) suction port on the ground and the ground for the return that can be restarted by sucking and exhausting the residual air in each air bag on the roof, The exhaust nozzle of the instrument panel is connected with a special joint device or the like (connection hose, reference numeral 22, reference numeral 17, reference numeral 18), and the accumulated air in the airbag is sucked and extracted (described in FIG. 7). In addition, it is possible to return to the initial standby state by inspecting and retightening the sheet tension line.
With the above operation, it is not necessary to go up to the roof for snow removal, it is possible to repeat the operation (work) of snow removal as many times as possible, the work can be removed safely and effortlessly, many workers This is a work suitable for the shape of the snow removal object, and can be appropriately dealt with on a desired scale without limitation, and it is preferable that measures can be taken easily. With a functional structure based on an unprecedented idea, it has a superiority, and it uses light electrical equipment such as general-purpose household vacuum cleaners and air compressors (organizations that can mobilize engine generators, inverter equipment, etc.). Air bag function with flexible on-site adaptability, and snow sliding sheet function (of cover sheet) that slides down naturally (note, for convenience of explanation, description is divided into two sheets: a base sheet of reference numeral 1 and a cover sheet of reference numeral 3 But these two This sheet is explained as two sheets at the top and bottom of the continuous sheet that is folded in a V shape at the top of the roof (* The reason is to prevent snow melt water from entering into the two sheets) However, it features an energy-saving and economical simple configuration that rationally utilizes the laws of nature, and has the unique function advantage of removing snow without climbing the roof. It is a convenient device for laying (temporary), and it is a snow removal device for snow with a sloped roof, which has the advantage of being able to remove snow safely without labor, and can be operated repeatedly any number of times.

This is due to the configurations of the first to third terms (A in FIG. 6) and the related instrument (1) for connection and the device operation (2) in the fourth term.
(Note: In order to make it easier to understand, reference numerals 1 and 3 have been described separately in terms of function, but in construction, the sheet is folded in a V shape at the highest position on the roof and laid {* In order to prevent snowmelt water from entering from the top side, it becomes a continuous series of sheets.)

FIG. 4 is a detailed explanatory view of the airbag apparatus of reference numerals 2 and 6, but the spread base sheet is fixed to the base of the roof, and the above-described airbag is suspended from the base sheet holder. Is held on. Each of the airbag bodies has nozzles for injecting compressed air and forced exhaust (each, caliber, inner diameter 6 mm, outer diameter 9 mm). , Diameter, inner diameter 6 mm, outer diameter 9 mm) are connected and extended to the instrument panel on the ground. Figure (B) is a pressure-resistant air hose with 2 systems, 2 stations, and 1 line.

Embodiments will be described in detail with respect to the above-described items 1 to 3 and (1) and (2) of the accessory parts (fourth item).
In FIG. 2C, there is a rectangular base-shaped waterproof sheet for laying, which is spread over the entire target area (range) on the target roof. Area intended for snow removal purpose (note, refers to the size of the area of a square area of the same area with the same conditions and conditions in consideration of the common slope and direction that function effectively, and the area) A rectangular sheet serving as a base for storing the starting device (airbag) of the present invention on the upper surface of the base sheet (hereinafter referred to as a base sheet (reference numeral 1)), In the laying process, the base sheet is cut into a corresponding size adjusted according to the shape of the required roof surface at the site, and the part from the bottom of the roof horse to the rain gutter at the bottom of the roof, that is, both sides of the roof slope On one side, Is laid down on the surface of one roof and hangs on a special fixing part provided in a place straddling the roof horse part using the eyelet hole processed at the upper end of the base sheet, or a long metal object The base sheet is connected to the roof horse with several hanging hands and fixed and held. In addition, the intention to prevent punch damage caused by existing protrusions on the roof, and an air bag installed on the top surface of the base sheet and inflated to start and function as a system (note, two types of codes described in detail later) 2 and 6) are required to prevent freezing or adhesion caused by flooding, which causes rupture damage when compressed air is injected (expanded). (Plate shape) and the back side naturally adapts to the roof shape (note, measures to prevent slipping and twisting deformation) Manufactured with a flexible and hard multilayer resinous sheet such as PVC or nylon. In addition, a material having high waterproof and water repellency (added and processed) is desirable in terms of application functions. In particular, in the next step, the surface that will be the mutual contact surface with the fabric surface that constitutes the airbag on the base sheet is the fabric surface due to chemical alteration due to the high temperature of the roof sunshine. As a preventive measure, it is desirable to use a sheet material coated with chemicals with specifications such as anti-altering agents and paraffin-based water-repellent wax. In particular, the device of the present invention is expected to last for a long time when the device is stuck under strong winter solar radiation. At first, there is a concern about the trouble that the airbag tears, so care must be taken to prevent these problems. In addition, as a measure to prevent adhesion and bonding of the shape and material of the fabric surface of the sheet, in order to improve the water-repellent effect and ventilation, and to reduce the contact area, the fabric surface (note, base contacting the airbag fabric surface) The processing specification of the pear-finished sheet (roughness) sheet is desirable in which the upper surface of the sheet and the lower (inner surface, etc.) surface of the cover sheet to be described later are roughed.

Next, with regard to the air bag (note, reference numerals 2 and 6) having a pressure-resistant structure that is placed on the upper surface of the base sheet (supplement, which becomes a component part of the intermediate layer upon completion) and inflated by injecting compressed air However, it is a system configuration designed to utilize the jacking force of the expansion and repulsion. Therefore, a net cloth of about 1 to 3 mm in thickness, such as nylon, aramid, polyester, etc., which has strong pressure resistance, is the main substrate, and is on the inner surface. Covered with airtight film sheet, bonded or laminated, water proofing, water-proofing, using high-pressure-resistant base fabric in a bag shape (note, sleeping bag type or bottomed paper bag) There are two types of molds, reference numerals 2 and 6.) A special high pressure-resistant airbag specification joined and closed with an adhesive solution, and the shape of the sleeping bag is expanded in a cylindrical shape depending on the tailoring shape (reference number 2, commonly known as) , Shura ) And a bottomed paper bag type (symbol 6, commonly known as a smart bag type), which also swells in a sandbag shape, and has an internal volume of 200 liters to 400 liters. 2 nozzle parts (each with an inner diameter of 6 mm, an outer diameter of 9 mm, nozzle, Note, the nozzle part (symbol 4) of one integrated device (joint) instrument is manufactured and installed by two systems of two systems (two separate mouth ends for air injection and forced suction exhaust). . The above-mentioned nozzle part uses a vinyl disc-shaped soft cushioning material (Ella-shaped mounting reinforcement base), and the nozzle part is reinforced and fixed, incised in a circular shape in the body of the airbag, The air bag with sufficient durability and pressure resistance is manufactured by fitting and bonding. Therefore, both of the above-mentioned two types of bag-shaped air bags are fitted with a pressure-resistant nozzle part (supply / discharge port). The diameter is 6 mm and the outer diameter is 9 mm. Therefore, it is desirable to have a device configuration that is as short as possible and that does not impair the airbag in operation. (Note, details of the instrument structure are shown in FIG. 4 with a nozzle 9 with two systems and two nozzles with the function of “with non-return valve” 9 for injection and “for porous” of 10 for forced exhaust.) In addition, a special connecting device that is connected to this nozzle device and connected to the instrument panel on the ground using a pressure-resistant air hose (inner diameter 6 mm, outer diameter 9 mm) ) And extending the pressure-resistant air hose (caliber inner diameter 6 mm outer diameter 9 mm, spiral hose, code 19) to the instrument panel on the ground. Therefore, a dedicated hose (symbol 7) that includes two pressure-resistant hoses for injection and forced exhaust in advance is prepared (note, numerals 11 and 12) and connected to each airbag on the roof. I will put it.

The air bag of the above item 2 is classified into two types according to the function purpose: 1, sleeping bag type (reference numeral 2), 2 and bottomed paper bag type (reference numeral 6), where 1 is the highest point of the roof and the tip Intended to function as a jacking force effect that expands into a perfect circle in a locally protruding shape and gains height, 2 is a solid, frozen, solid, heavy, frozen snow mass that hangs down at the bottom of the roof Therefore, it is intended to be a specification that distributes the load and spreads the load area and distributes it effectively, and has a function configuration that can exert jacking force corresponding to weight by spreading laterally. It is. Distinguishing from the shape, two types of airbags, a sleeping bag type and a bottomed paper bag type (named), were used. Therefore, there is a relationship between the size (standard) of the airbag and the required number of installations. The roof area is divided into vertical lines (with high and low slopes), and each set (with a set is a snow drain function device on one sheet) It is possible to configure the number of airbags in the upper, middle (one or more) and lower stages according to the width (length of the vertical slope). During operation, it is possible to start and remove snow in order from the bottom sharing the area, as desired, and a set system with the roof divided vertically (one set up and down for each set. A system that can remove snow), and for each set, each side has four or more airbags in a series of two upper and lower (inside, one or more), lower, left, and right sides. Installed, air bag with two air hoses (symbol 7) laid The set type is configured to be connected to the left side and the right side, extending downward along the side of the base sheet of the underlay, and extending the lower end until reaching the control panel on the ground (explained in Fig. 3) ) Is appropriate and desirable. The installed upper stage airbag (sleeping bag type) is located at the upper edge of the lower base sheet, and the middle and lower airbags are located at the lower position of the base sheet deployed in the middle and lower stages. The base sheet will be fastened directly to the base sheet surface (eyelet processing), or an appropriate metallic long object, and will be fixed to the base sheet at the crossing position, respectively, and air bag However, it is held in a flat (vacuum state) single sheet form suspended in the base sheet.

About the cover sheet of item 3 above, b) Covers the entire device with the above code 1 and code 2 installed, b) the purpose of weather resistance maintenance, and c) surface effect that snow slides down automatically when the system is activated It is a cover sheet with multiple functions that has the function and role to maintain and promote the function. Therefore, the cover sheet is a special functional sheet that has the function of preventing the penetration of melted water and rainwater and promoting the natural sliding of snow, but it has a glossy surface and is hydrophobic and water repellent. In addition, it is a thick (about 1 to 3 mm) PVC synthetic fiber sheet (the surface is the effect of a snow-sliding sheet) that can prevent permeation freezing of water molecules, and the back inner surface has a satin finish (adhesion prevention) Is desirable. For cost effectiveness, it is possible to substitute a commercially available high-quality blue sheet, but use a sheet that covers the entire roof and has a functional configuration that can prevent the infiltration and backflow of raindrops and suga leaks (melted snow water on the roof). It is desirable to connect to the base sheet (reference numeral 1) on the bottom at the top of the roof, and connect to the folded back in a V-shape (to prevent intrusion of snowmelt water, etc.) Cover the entire device with a length that reaches the deepest position of (overhang), and store it in series with the attached air hose etc. (Note: For convenience of explanation, the two sheets of the base sheet of reference numeral 1 and the cover sheet of reference numeral 3 have been described separately. However, these two sheets are one continuous sheet and are V-shaped at the top of the roof. (The reason is to prevent the intrusion of snowmelt water from the top of the two sheets in the two sheets.)

The above item (1) is a description of the equipment used for installation or connection of the components of the apparatus described above, but the special specification is for air injection incorporated at the time of manufacturing the airbag. , Two-system two-port integrated nozzle device for forced exhaust (each inner port diameter is 6 mm, outer diameter is 9 mm, reference numeral 4 is an injection nozzle, reference numeral 13 is an air check valve, reference numeral 14 is forced exhaust The device of the perforated pipe specification “prevention of blockage”), but the instrument panel on the ground that reaches the tip connected to and extended to this has two device terminal parts (joint part) of air supply and exhaust, The exhaust nozzle (reference numeral 20) is provided with a manual air cock valve (used for switching during supply and exhaust). If maintenance can be performed, it is desirable to install an air pressure meter device for monitoring the pressure of the airbag. When starting a normal snow drainage system, it is possible to perform air injection operations while monitoring the behavior of snow accumulation on the roof from the safety zone at the site. However, it is possible to deal with snow removal by adapting flexibly. However, for pressure monitoring and safety, it is desirable to equip and organize an overpressure alarm device and an overpressure automatic release valve device. Regarding the explanation of the operation of the system function of the present invention in the following item (2), when the winter snowfall progresses and the snowfall of the snow on the roof is necessary, it is appropriate time (no wind and temperature rise is preferable) ) To open the pulling line on the entire surface of the cover sheet (reserving some securing lines in case of a gust of wind), making the cover sheet behavior associated with the expansion of the internal airbag easy to freely deploy and free Then, after starting the electric air compressor and maintaining the specified compressed air pressure, inject compressed air into the compressed air inlet (already connected to a pressure hose to the airbag) on the instrument panel on the ground. When the airbag (with check valve) is inflated, the cover sheet gradually lifts with jacking force and pushes up the snow mass together, and the roof snow naturally falls on the cover sheet of the sloped roof. However, the order of the compressed air injection of the air bag on the roof starts from the air bag in the lower part of the roof, and it is performed in the upper stage sequentially, depending on the conditions, but snow accumulation in the upper part of the roof to be connected is induced. Therefore, it is expected to descend all at once, so it is necessary to check safety measures in advance, such as confirming the safety zone space of the fall place on the ground and the snowfall fall prevention fence, etc. . Stop air injection as soon as the snow on the roof starts to slide down (to prevent air bag bursting).

Next, with regard to (2) in item 4, when the above-described roof lower layer and upper layer airbags are activated and snow removal on the roof is completed, the next is to perform forced suction exhaust in the airbag, Open the exhaust air cock (closed at the beginning) of the exhaust air carefully (notes, there is a risk that strong high-pressure air may protrude at the beginning). Monitor the exhaust pressure situation, air cleaner on the ground Connect the suction port of (Vacuum vacuum cleaner) and the exhaust port nozzle of the instrument panel with the special equipment (reference 22) and the equipment of reference 17 and 18 and switch on the air in the airbag that was previously injected. Forced suction extraction is performed (explained in FIG. 7). When this work is completed, start the initial restoration work, tighten the rope (tie) of the cover sheet, pull the four sides to prevent the wind from entering the cover sheet, and repeat the storage process as before Then, complete the work to restore the original situation, and return to the standby state. Therefore, it is easy to start snow draining again at any time, and it is easy to start and it is possible to perform repeated operations. It is economical, safety using natural laws, and outstanding utility that can drain snow without labor. There is an innovative device configuration that has never existed before, and it is effective.

The air bag specification of the main body of the present invention has simple adaptability of function, simple material configuration, repetitive function of the device, and economy superior in reconstruction, yet a lift that can exert a powerful effect It has been devised a way to deal with soft (flexible) in the field of roof snow removal that has been highly efficient and has been difficult to mechanize for many years without measures for the past. As technical techniques, 1) scrape snow with a heavy arm with long arm, 2) discharge or discharge hot water, electrothermal snow melting, 3) blow off with high pressure water discharge or high pressure air, all of which are enormous Cost and waste of resources. Once again, the power and efficiency of this airbag system is excellent and it is necessary to recognize extremely important functionality. This remarkable feature will be used in the snowfall areas, such as structures with light and soft structures that are unavoidable in terms of cost, large and small acrylic carports, storage rooms, equipment rooms, etc. It is a function that should be fully utilized, and it is considered that there are sufficient fields and issues that can be utilized industrially.
