Description

[Technical Field]

[0001] The present invention relates to a snow remover for removing snow accumulated on a roof. [Background Art]

[0002] Conventionally, in snowfall areas, roof snow removal is performed in winter. When performing roof snow removal, for example, work such as climbing onto a roof heavily covered with snow and scraping off the snow is performed, which requires a great deal of labor and is accompanied by great danger. Therefore, for households of elderly people and the like, it is difficult to perform snow removal work by themselves, and even when entrusting the work to a professional contractor, it is not practical to perform snow removal frequently due to problems such as the cost burden. If snow removal work is not properly performed, damage to people caused by falling snow or damage to buildings caused by the weight of snow may occur, so it is desired to properly perform snow removal work. Under such circumstances, various methods for snow removal work have been conventionally proposed. For example, a method is known in which an instrument provided with a lightweight shovel at the end of a long handle is used to scrape snow off a roof from the ground. Further, Patent Document 1 discloses a roof snow remover, which works by throwing a snow scraper body provided with a snow scraper plate onto the roof from the ground and pulling a wire connected to the snow scraper body, so that the snow scraper plate scrapes snow off the roof.

[0004] However, conventional technologies, including the technology described in Patent Document 1, still require a great deal of effort to remove snow from an entire roof, and the safety of the work is not sufficient, as there is a possibility that the shoveled snow may fall on the workers. In other words, with conventional technology, it was difficult to safely and efficiently remove snow from roofs.

[0005] The objective of this invention is to realize a technology for removing snow from roofs more safely and efficiently. [Means for solving the problem]

[0006] To solve the above problems, a snow removal machine according to one embodiment of the present invention is provided. A linear component for snow removal installed on the roof, An end support is installed at a first position on the roof and supports one end of the linear member for snow removal, A holder is installed at a second position on the roof, horizontally spaced apart from the end support, and slidably supports the linear member for snow removal, A winding machine that winds up one end of the linear snow-clearing member at a position where the linear snow-clearing member, via the holder, extends vertically downward from the side edge of the roof, A linear member for operation is connected to a portion of the linear member for snow removal that is stretched between the end support and the holder, extends along the roof surface of the roof, and extends vertically downward from the lower end of the roof surface, A guide rail is installed along the eaves of the roof and guides the horizontal movement of the linear member for operation, Equipped with, The winding machine is in a state where it can unwind the linear member for snow removal, and the end of the operating linear member is operated, so that the operating linear member is guided by the guide rail and moves along the eaves of the roof, thereby causing the linear member for snow removal to scrape down the snow from the roof. [Effects of the Invention]

[0007] According to the present invention, it is possible to realize a technology for removing snow from roofs more safely and efficiently. [Brief explanation of the drawing]

[Figure 11] This is a schematic diagram showing the state after snow removal from the roof has been reset. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below with reference to the drawings. [First Embodiment] The snow remover according to the present embodiment is configured such that a pulling wire-shaped member (for operation by an operator) is connected to one point of a snow-raking wire-shaped member that is stretched across the upper end of a roof substantially parallel to the eaves, and the pulling wire-shaped member can be operated from a safe position such as the ground. The snow-raking wire-shaped member is configured to move along the roof surface while maintaining a predetermined distance from the roof surface when the connected portion is pulled by the pulling wire-shaped member. Therefore, when snow accumulates on the roof with the snow-raking wire-shaped member stretched across the upper end of the roof, when an operator holds the tip end of the pulling wire-shaped member (the end opposite to the one end connected to the snow-raking wire-shaped member) and moves along the eaves of the roof, the snow-raking wire-shaped member moves along the roof surface, and the snow on the roof is raked down.

[0010] Therefore, the operator can efficiently rake down snow from the entire roof by moving in a safe position. That is, according to the present invention, a technique for removing snow from a roof more safely and efficiently can be realized. Further, the snow remover according to the present embodiment includes a reset mechanism for returning the snow-raking wire-shaped member to the initial state stretched across the upper end of the roof after snow removal is performed. Therefore, after snow removal is performed, it can be set to a state in which snow removal can be performed again by a simple operation. Hereinafter, a specific configuration of the snow remover according to the present embodiment will be described.

[0011] Configuration Figure 1 is a schematic diagram showing the overall configuration of the snow remover 1 according to the present embodiment. Further, Figure 2 is a schematic diagram showing a component for resetting in the snow remover 1. The snow remover 1 shown in Figure 1 and Figure 2 is an embodiment of the snow remover to which the present invention is applied, and shows an example installed on a gable roof.

[0012] As shown in Figures 1 and 2, the snow removal machine 1 in the present invention comprises an end support 10 installed at one end of the ridge, a sliding holder 20 installed at the other end of the ridge, a guide rail 30 installed along the eaves, and a winding machine 40 for resetting the snow removal machine 1. One end of a snow-shoveling wire rope W1 is connected to the end support 10, and the other end of the snow-shoveling wire rope W1 is connected to one end of a reset wire rope W2 near the sliding holder 20 (on the end support 10 side). One end of the reset wire rope W2 is connected to the other end of the snow-shoveling wire rope W1, and is slidably held by the sliding holder 20 while the other end is wound onto the winding machine 40. Furthermore, one end of a pull-in wire rope W3 is connected to the connection point of wire ropes W1 and W2, and the other end of wire rope W3 hangs down near the ground via the guide rail 30. Wire ropes W1 to W3 are made of materials that are less susceptible to deterioration over time due to ultraviolet rays, etc., such as resin, metal, or materials with a metal core coated with resin.

[0013] For the sake of clarity, the following will be referred to as follows: point A for the position of the end support 10, point B for the position of the sliding holder 20, point C for the end position on the guide rail 30 below the sliding holder 20, point D for the under-eaves position below point C on the ground, point E for the under-eaves position on the opposite side of point D on the ground, point F for the end position on the guide rail 30 opposite to point C, and point G for the position of the winding machine.

[0014] The end support 10 is made of a weather-resistant material such as stainless steel and fixes the end (fixed end) of the wire rope W1 to one end (point A) of the ridge on the roof. Figure 3 is a schematic diagram showing an example of the configuration of the end support 10. In Figure 3, the end support 10 comprises a base 11 fixed to the roof (point A, which is one end of the ridge) with anchor bolts or the like, a rod 12 rising from the base 11, and an annular portion 13 formed at the tip of the rod 12. The areas where the base 11 is fixed to the roof (such as where anchor bolts are installed) are sealed with caulking to prevent rainwater leakage. Furthermore, one end of the wire rope W1 is annular and is supported by engaging with the annular portion 13. The annular portion 13 of the end support 10 is formed at a predetermined height (for example, 8 cm) from the roof surface and supports one end of the wire rope W1 at a predetermined distance from the roof surface.

[0015] The sliding holder 20 is made of a highly weather-resistant material such as stainless steel and slidably holds the wire rope W2 at the other end (point B) of the ridge on the roof. Figure 4 is a schematic diagram showing an example of the configuration of the sliding holder 20. In Figure 4, the sliding holder 20 comprises a base 21 fixed to the roof (point B, which is the other end of the ridge) with anchor bolts or the like, a rod 22 rising from the base 21, an annular portion 23 formed at the tip of the rod 22, and a pulley 24 through which the wire rope W2 is stretched.

[0016] Similar to base 11, base 21 is sealed with caulking at the points where it is fixed to the roof (such as anchor bolt locations) to prevent rainwater leakage. A wire rope W2 is inserted through the annular portion 23, with one end connected to the wire rope W1 on the side of point A from the sliding holder 20. The wire rope W2, which is inserted through the annular section 23, is stretched over the pulley 24 and changes direction vertically downward, with the other end being wound onto the winding machine 40.

[0017] Furthermore, one end of wire rope W3 is connected to the connection point where wire ropes W1 and W2 are joined on the A side of the sliding holder 20, and the other end of wire rope W3 hangs down from the roof via the guide rail 30. The wire rope W2 slides within the annular section 23 when the wire rope W3 pulls in wire ropes W1 and W2, or when the other end is wound onto the winding machine 40. The pulley 24 rotates in accordance with the sliding of the wire rope W2, guiding the movement of the wire rope W2.

[0018] The guide rail 30 is made of a highly weather-resistant material such as stainless steel and slidably supports the wire rope W3 at a position along the eaves at the edge of the roof surface (between point C and point F). Figure 5 is a schematic diagram showing an example of the configuration of the guide rail 30. In Figure 5, the guide rail 30 comprises a support member 31 installed at the lower end position (point C) of the sliding holder 20 on the roof surface, a support member 32 installed at the lower end position (point F) of the end support 10 on the roof surface, and a rail member 33 supported by the support members 31 and 32.

[0019] The support members 31 and 32 are fixed to the roof with screws or anchor bolts, and the areas where the support members 31 and 32 are fixed to the roof (such as where the screws or anchor bolts are installed) are sealed with caulking to prevent rainwater leakage. Furthermore, the support members 31 and 32 support the rail member 33 at a predetermined height (e.g., 8 cm) from the roof surface and at a predetermined distance (e.g., 5 cm) from the eaves outward from the roof. Therefore, when the wire rope W3 slides along the rail member 33, it is maintained at a predetermined height (e.g., 8 cm) from the roof surface and a predetermined distance (e.g., 5 cm) from the eaves of the roof.

[0020] Furthermore, the rail member 33 is supported at both ends (points C and F) by support members 31 and 32, and no members are installed to obstruct the sliding of the wire rope W3 in the area where the wire rope W3 slides (between points C and F). Therefore, if a worker holds the other end of the wire rope W3 and moves it, it is possible to prevent the wire rope W3 from coming into contact with the roof and damaging it. Furthermore, the lower outer surface side of the rail member 33 (the side opposite to the surface on which the wire rope W3 slides) may be appropriately supported in the portion between the support members 31 and 32.

[0021] The winding machine 40 is made of a metal material such as stainless steel or steel, and is used to wind up, fix, or release (pay out) the other end of the wire rope W2. Figure 6 is a schematic diagram showing an example of the configuration of the winding machine 40. In Figure 6, the winding machine 40 includes a bracket 41 fixed to the wall of a building, a winding shaft 42 rotatably supported by the bracket 41, a handle 43 connected to the rotation axis of the winding shaft 42, and a stopper 44 that restricts the rotation of the winding shaft 42. In the example configuration shown in Figure 5, the winding machine 40 is installed inside a case 45 with a door that covers the entire winding machine 40. The wire rope W3 is inserted through a through hole provided in the case 45, and the winding and unwinding of the winding machine 40 is not obstructed.

[0022] The winding machine 40 winds up the wire rope W2 to set the snow removal machine 1, and with the connection points of the wire ropes W1 to W3 located near the sliding holder 20, the rotation is restricted by the stopper 44. That is, with the wire rope W1 stretched almost in a straight line between points A and B, the movement of the wire ropes W1 and W2 is restricted. Furthermore, when snow removal work is performed in the snow removal machine 1, the rotation restriction of the winding machine 40 by the stopper 44 is released, and the wire rope W2 is released. In this state, when the other end of wire rope W3 is pulled in by the worker and the connection point of wire ropes W1 to W3 moves from point B to point F, wire rope W2 is unwound from the winding machine 40, and wire rope W1 can cut the snow on the roof, making it possible to scrape off the snow from the entire roof.

[0023] [Operation] Next, we will explain the operation of snow removal using snow removal machine 1.

[0024] Figures 7 to 11 are schematic diagrams showing the operation of snow removal using the snow removal machine 1. Figure 7 is a schematic diagram showing the initial state of snow accumulation on the roof with the snow removal machine 1 in place. Figure 8 is a schematic diagram showing the process 1 (initial stage of snow removal) of snow removal from the roof. Figure 9 is a schematic diagram showing the process 2 (final stage of snow removal) of snow removal from the roof. Figure 10 is a schematic diagram showing the state after snow removal from the roof has been completed. Figure 11 is a schematic diagram showing the state after the snow removal machine 1 has been reset after snow removal from the roof.

[0025] [Preparation process] When the snow removal machine 1 is used, first, the wire rope W2 is wound up by the winding machine 40, and a preparatory step is performed to set the wire ropes W1 to W3 to an initial state where the connection points are located near the sliding holder 20. That is, the wire rope W1 is stretched between points A and B, approximately parallel to the eaves, and is kept taut. At this time, the end support 10, the sliding holder 20, and the guide rail 30 support the wire ropes W1 to W3 at a predetermined height from the roof surface, thus preventing damage to the roof surface due to contact between the wire ropes W1 to W3. In snow removal machine 1, if snow removal is not required, the preparation process continues. Then, when snow accumulates on the roof due to snowfall, it results in a state like the one shown in Figure 7.

[0026] [Snow removal process] When it becomes necessary to remove snow from the roof, the door of case 45 is opened, the stopper 44 of the winding machine 40 is released, and the wire rope W2 is released (in a state where it can be unwound). Then, the worker holds the other end of the wire rope W3 and begins to move from point D to point E. At this time, since there is slack in the length of the wire rope W3, the worker can move from point D to point E while avoiding the area where snow will fall from the roof. As shown in Figure 8, the wire rope W3 connected to the wire rope W1 pulls the connection point of the wire rope W1 downwards from the roof surface, moving the connection point of the wire rope W1 along the roof surface towards point F. At this time, the wire rope W1 moves while cutting the snow accumulated on the roof, so the area of ​​the roof surface that the wire rope W1 has passed through is cleared of snow.

[0027] Then, when the worker reaches point F, the wire rope W1 further removes snow from the roof, resulting in a state where snow has been shoveled down from a wider area of ​​the roof surface, as shown in Figure 9. Once a worker reaches point E, they can move further beyond point E to stretch the wire rope W1 almost linearly between points A and F. This removes the snow from the entire roof, resulting in a state where the snow has been scraped off the roof surface, as shown in Figure 10. As described above, the end support 10, sliding holder 20, and guide rail 30 support the wire ropes W1 to W3 at a predetermined height from the roof surface. When the wire ropes W3 are pulled in, a certain tension is applied to the wire ropes W1 to W3, thus preventing damage to the roof surface from contact with the wire ropes W1 to W3 during the snow removal process.

[0028] [Reset process] After this, the operator turns the handle 43 of the winding machine 40 to wind up the wire rope W2, returning the connection points of the wire ropes W1 to W3 to the same position as the initial state, as shown in Figure 11. Then, the rotation of the winding machine 40 is restricted by the stopper 44 of the winding machine 40, and the door of the case 45 is closed. As a result, the snow removal machine 1 is reset to its initial state. As described above, the end support 10, sliding holder 20, and guide rail 30 support the wire ropes W1 to W3 at a predetermined height from the roof surface, and a constant tension is applied to the wire ropes W1 to W3 when the winding machine 40 winds up the wire rope W2. Therefore, even in the reset process, damage to the roof surface due to contact between the wire ropes W1 to W3 is suppressed.

[0029] [effect] As described above, the snow removal machine 1 according to this embodiment connects a retraction wire rope W3 to a point on a snow removal wire rope W1 that is stretched across the upper end of the roof approximately parallel to the eaves, and the retraction wire rope W3 can be operated from a safe position such as the ground. When the connection part of the snow removal wire rope W1 is retracted by the retraction wire rope W3, the snow removal wire rope W1 moves along the roof surface while maintaining a predetermined distance from the roof surface. Therefore, when snow accumulates on the roof with the snow-clearing wire rope W1 stretched across the upper edge of the roof, if a worker holds the end of the pull-in wire rope W3 (the end opposite to the end connected to the snow-clearing wire rope W1) and moves along the eaves of the roof, the snow-clearing wire rope W1 will move along the roof surface, and the snow on the roof will be shoveled down. Therefore, by moving in a safe position, workers can efficiently clear snow from the entire roof.

[0030] Furthermore, after snow removal is complete, a reset is performed to return the snow-shoveling wire rope W1 to its initial state, stretched across the upper edge of the roof (between point A and point B). Therefore, after snow removal has been performed, it can be easily reset to a state where snow removal is possible again. Thus, according to the snow removal machine 1 of this embodiment, it is possible to realize a technology for removing snow from roofs more safely and efficiently.

[0031] [Specific effects] As a result of having the effects described above, using the snow removal machine 1 according to this embodiment can provide specific effects such as the following. (1) It can be used by the elderly and people with little physical strength. (2) Snow can be safely removed from the ground without having to climb onto the roof. (3) After snow removal, the system can be easily reset from the ground. (4) Because it can be easily reset, snow can be removed from the roof frequently during the snowy season, preventing large amounts of snow from accumulating on the roof. As a result, damage such as distortion or collapse of the building is suppressed. (5) Snow removal can be performed while preventing damage to the roof, eaves, and walls from contact with the wire rope. (6) Without using electricity, motors, etc., a person of average physical strength can remove snow from the entire roof by themselves in a short amount of time. (7) The installation components are made of weather-resistant materials such as stainless steel, and the wire rope is made of a material that does not deteriorate easily over time due to ultraviolet rays, etc., thereby suppressing deterioration of each part of the snow removal machine 1. (8) The snow removal machine 1 can be installed relatively easily without requiring significant expense, and once installed, it can be used for a long period of time (for example, 20 years or more of continuous use) with inspections only about once a year.

[0032] [Differentiation] In addition to the configuration shown in the above-described embodiment, the snow removal machine 1 according to this embodiment can be modified in various ways.

[0033] [Example 1] In the embodiments described above, wire ropes W1, W2, and W3 were used as examples of wire-like members, but the shape of the wire-like members can be various forms. For example, rope-like members with a roughly circular cross-section, members with a roughly elliptical cross-section, or wide belt-like members can be used. Furthermore, the diameter of the wire-like member can be varied depending on the snow quality in the area where the snow removal machine 1 is installed. This allows for a more appropriate configuration to suit the actual conditions under which the snow removal machine 1 is installed.

[0034] [Differentiation 2] In the above-described embodiment, when snow removal is performed using the snow removal machine 1, it was explained that the worker holds the tip of the wire rope W3 (wire-like member for pulling in) while moving it. However, the tip of the wire rope W3 can be made into a shape suitable for being held by the worker. For example, a gripping handle (such as a ring-shaped or triangular handle) can be attached to the end of the wire rope W3. Alternatively, a gripping rod may be attached to the end of the wire rope W3. By providing a rod, it becomes possible to operate the wire rope W3 from a position away from the eaves, or to move it while avoiding areas where snow may fall from the roof when removing snow.

[0035] [Difference 3] In the above embodiment, the case in which the end support 10 and the sliding holder 20 are installed at the top of the roof (the ridge) was used as an example, but the installation position of the end support 10 and the sliding holder 20 is not limited to this. For example, if a structure (such as a chimney or skylight) exists at the top of the roof or on part of the roof surface, the end support 10 and the sliding holder 20 can be installed at a position that avoids the structure (at a height below the structure). In other words, on the roof surface at a lower position than the structure, an end support 10 can be installed at one end in the horizontal direction, and a sliding holder 20 can be installed at the other end in the horizontal direction at the same height as the end support 10. This prevents the roof structure from interfering with the operation of the wire-like member, allowing snow removal by the snow removal machine 1 to be performed properly. Furthermore, since removing snow below a certain height on the roof is expected to cause the snow above to lose its support and fall from the roof, a certain level of snow removal effect can be obtained even with a structure that uses wire-like members stretched across below the roof structure.

[0036] [Differentiation Example 4] In the above embodiment, the linear members, wire ropes W1 to W3, were described as being made up of separate wire ropes. However, the linear members installed in the snow removal machine 1 can be made up of a single linear member that is split into two halves, or by connecting another linear member to a linear member that has been split into two halves. Furthermore, the wire ropes W1 to W3 in the above-described embodiment can be of different shapes or thicknesses depending on their function. This allows for flexible modification of the components that make up the snow removal machine 1, making it possible to remove snow more efficiently.

[0037] [Difference 5] In the above-described embodiment, the snow removal machine 1 was explained as being installed on one side of the roof, but the snow removal machine 1 can be installed on multiple sides of the roof. For example, in the case of a gable roof as shown in Figure 1, the snow removal machine 1 can be installed on the roof surface at the back, in addition to the roof surface shown in Figure 1. Because the snow removal machine 1 can be installed at low cost and in a simple manner, it is easy to install it on multiple roof surfaces. When snow removal machines 1 are installed on multiple roof surfaces, damage to buildings caused by snow accumulation can be prevented more effectively.

[0038] The snow removal machine 1, configured as described above, includes wire ropes W1 to W3, end support members 10, sliding holders 20, guide rails 30, and a winding machine 40. Wire ropes W1 and W2 will be installed on the roof. The end support 10 is installed at a first position on the roof and supports one end of the wire rope W1. The sliding holder 20 is installed at a second position on the roof, horizontally spaced apart from the end support 10, and slidably supports the wire rope W2. The winding machine 40 winds up one end of the wire rope W2 when the wire rope W2, which has passed through the sliding holder 20, extends vertically downward from the side edge of the roof. Wire rope W3 is connected to a portion of wire ropes W1 and W2, which are stretched between the end support 10 and the sliding holder 20, and extends along the roof surface of the roof, extending vertically downward from the lower end of the roof surface. The guide rail 30 is installed along the eaves of the roof and guides the horizontal movement of the wire rope W3. With the winding machine 40 ready to unwind the wire rope W2, the end of the wire rope W3 is operated, and the wire rope W3 is guided by the guide rail 30 and moves along the eaves of the roof, causing the wire rope W1 to scrape down the snow from the roof. As a result, when snow accumulates on the roof while the snow-clearing wire rope W1 is stretched across the roof, the worker can hold the end of the operating wire rope W3 and move along the eaves of the roof, causing the snow-clearing wire rope W1 to move along the roof surface and clear the snow from the roof. Therefore, by moving in a safe position, workers can efficiently clear snow from the entire roof. Therefore, it is possible to realize technology that allows for safer and more efficient snow removal from roofs.

[0039] The end support 10 and the sliding holder 20 support the wire ropes W1 and W2 at positions spaced apart from the roof surface. The guide rail 30 guides the linear snow removal member at a position separated from the roof surface. This prevents damage to the roof surface caused by contact between the wire ropes W1 and W3.

[0040] The guide rail 30 guides the wire rope W3 at a position that protrudes outward from the eaves of the roof. This prevents the wire rope W3 from coming into contact with the roof and damaging it.

[0041] The winding machine 40 guides the wire rope W3 along the guide rail 30 and moves along the eaves of the roof, so that after the wire rope W1 has cleared the snow from the roof, it winds up the wire rope W2, resetting the wire rope W2 to a state where it is stretched between the end support 10 and the sliding holder 20. This allows you to easily reset the area to a state where snow removal is possible after the snow has been removed.

[0042] The end support 10 is installed on one side end of the upper end of the roof. The sliding holder 20 is installed on the other side end of the upper end of the roof. This makes it possible to efficiently remove snow from the entire roof, starting from the top edge.

[0043] Wire rope W3 is connected to wire ropes W1 and W2 at a position near the sliding holder 20 when wire rope W1 is stretched between the end support 10 and the sliding holder 20. This allows a worker holding the end of the wire rope W3 to move along the eaves of the roof, enabling the wire rope W1 to efficiently clear snow from one side of the roof to the other.

[0044] Furthermore, the present invention is not limited to the embodiments described above, and any modifications, improvements, etc., that can achieve the objectives of the present invention are included within the scope of the present invention. In other words, the present invention can be applied to various buildings and other structures that require snow removal.

[0045] Although several embodiments of the present invention have been described above, these embodiments are merely illustrative and do not limit the technical scope of the present invention. The present invention can take various other embodiments, and furthermore, various modifications such as omissions and substitutions can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention as described herein, and are also included in the scope of the invention and its equivalents as described in the claims.
