Description

[Technical Field]

[0001] The present invention relates to a protective cover that covers and protects the driver's seat and its surroundings in a machine such as heavy machinery. More specifically, the present invention relates to a protective cover that protects the driver's seat and its surrounding equipment from water, dirt, damage from pests and vermin, and deterioration due to sunlight, has good drainage and dust removal properties, is easy to attach and remove, and does not easily come off the machine to which it is attached, and a method for attaching the protective cover. [Background technology]

[0002] Heavy machinery used outdoors comes in two types: "cab specifications," in which the driver's seat is located inside a box-shaped cab, and "canopy specifications," in which there is only a canopy section above the driver's seat and two or four supporting pillars, but no partition members are provided to surround the driver's seat and its peripheral equipment (hereinafter referred to as the "operator section"), leaving the operator section exposed.

[0003] With the cab model, the operator's area is surrounded by partitions, so it is not exposed to sunlight, rain, or wind, and deterioration of the driver's seat and other parts progresses slowly.

[0004] On the other hand, in the case of canopy-type machines, there is no partition around the operator unit other than the canopy, so the operator unit is exposed to the elements. This means that the operator unit is directly exposed to the effects of sunlight, wind, rain, and damage from pests and vermin. Not only do the seat and equipment get wet and dirty, but the surface fabric of the driver's seat and the surface paint of the surrounding equipment can crack and peel due to sunlight, and the wetness and dirt can also affect the performance of the equipment itself, resulting in significant deterioration in quality and functionality. Furthermore, during construction, heavy machinery is often left on site, and in this case it is constantly exposed to the outside air, which, combined with the temperature changes between day and night, tends to accelerate deterioration of the operator unit even more quickly.

[0005] To solve this problem, Patent Document 1 discloses a "protective cover for heavy machinery and its use" that covers and protects the front section to the operator section of a canopy-equipped heavy machinery with a sheet-like protective cover. This protective cover for heavy machinery has a sheet-like shape, and the front and rear sections of the protective cover are fixed with fixing ropes using mounting pieces or the like, and the top surface of the protective cover is hung from the eaves and fixed to the machine body, thereby covering the operator section of the machine body.

[0006] Furthermore, Patent Document 2 discloses a "protective cover for heavy machinery" that protects a canopy-equipped heavy machinery by covering the front section to the operator section with a three-dimensionally formed protective cover. This protective cover for heavy machinery covers the operator section of the machine by attaching a fixing rope to the bottom end of the protective cover and tightening it horizontally, and further by hanging the top surface of the protective cover from the eaves and fixing it to the machine body.

[0007] Furthermore, Patent Document 3 discloses a cover body having a three-dimensional area for covering the upper front part of the vehicle to be covered. This three-dimensional shape has an inclined surface, and water droplets that fall on the inclined surface slide down the inclined surface, thereby maintaining good drainage on the inclined surface. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Patent Publication No. 2023-155569 [Patent Document 2] Patent Publication No. 2022-124115 [Patent Document 3] Patent Publication No. 2024-10948 Summary of the Invention [Problem to be solved by the invention]

[0009] However, because the protective cover described in Patent Document 1 is formed in a sheet shape, fixing ropes must be used to stretch the protective cover in both the front and rear directions so that the sheet-like protective cover conforms to the shape of the aircraft body, and the top surface of the protective cover must be hung from the eaves and fixed to the aircraft body, making installation and removal work extremely time-consuming.

[0010] Furthermore, although the protective cover described in Patent Document 2 is formed three-dimensionally, the bottom portion must be fastened with a fixing rope to secure it to the machine body, and like the protective cover described in Patent Document 1, the installation and removal work is time-consuming.

[0011] Furthermore, in the vehicle cover of Patent Document 3, the inclined surface and the seat area that covers the seat portion of the vehicle to be covered are not provided continuously, so there is a risk that water may accumulate in the seat area. Alternatively, if there is an opening between the inclined surface and the seat area, water droplets, dust, etc. may enter through the opening and soil the vehicle to be covered, or wind may blow through the opening and cause the vehicle cover to detach from the vehicle to be covered.

[0012] Furthermore, the inclination angle of the upper surface of the protective covers in Patent Documents 1 and 2 and the inclined surface of the vehicle protective cover in Patent Document 3 is gentle, and all of the covers in Patent Documents 1 to 3 are attached with a certain amount of slack, which makes the upper surface of the cover prone to bending. As a result, rainwater and dust tend to accumulate in the bent portion, and the weight of the rainwater causes the protective cover to sink, causing the bottom of the protective cover to curl up, exposing the aircraft or the like to which it is attached, which may lead to further deterioration.

[0013] In other words, although Patent Document 1, Patent Document 2 and Patent Document 3 can protect the machine body to which the device is attached from deterioration due to sunlight and the like, they do not solve the problems of time-consuming attachment and detachment, the problem that the device easily comes off, and the problem that rainwater, dust and the like tend to accumulate.

[0014] The present invention has been devised in light of the above points, and aims to provide a protective cover and a method for attaching the protective cover that protects the driver's seat and its peripheral equipment from getting wet, getting dirty, being damaged by pests and vermin, and being deteriorated by sunlight, has good drainage and dust removal properties, is easy to attach and remove, and is unlikely to come off the aircraft to which it is attached. [Means for solving the problem]

[0015] In order to solve the above problems, the protective cover of the present invention comprises: a three-dimensional covering portion having an inclined surface composed of a substantially smooth first inclined surface having a predetermined area and provided at a predetermined inclination angle; a substantially smooth second inclined surface having a predetermined area and provided at a predetermined inclination angle, the second inclined surface being continuous with the first inclined surface at a minor angle so that the boundary region with the first inclined surface bulges outward; and a substantially smooth upright surface being continuous with one end of the inclined surface at an acute angle; and a side covering portion having at least a portion thereof a substantially smooth continuous inclined surface that is continuous with the three-dimensional covering portion at one end and has an open shape at the other end, is continuous with the inclined surface, and is provided at an inclination angle greater than the inclination angle of the inclined surface.

[0016] Here, by providing a protective cover that includes a three-dimensional covering portion and a side covering portion that is continuous at one end with the three-dimensional covering portion and has an open shape at the other end, it becomes possible to enclose the machine to be attached within the protective cover and block out wind, rain, sunlight, etc., thereby suppressing damage to the machine to be attached from wind, rain, dust, pests and vermin, and deterioration due to sunlight, etc.

[0017] In addition, the first inclined surface is generally smooth and has a predetermined area and is provided at a predetermined inclination angle, allowing water droplets and dust that fall onto the first inclined surface to slide down quickly, thereby providing good drainage and dust removal properties.

[0018] In addition, the second inclined surface is generally smooth and has a predetermined area and is provided at a predetermined inclination angle, allowing water droplets and dust that fall onto the second inclined surface to slide down quickly, thereby providing good drainage and dust removal properties.

[0019] Furthermore, an inclined surface consisting of a first inclined surface and a second inclined surface that is continuous with the first inclined surface at a minor angle so that the boundary area between the first inclined surface bulges outward allows water droplets and dust that fall onto the inclined surface to slide down, splitting between the first inclined surface and the second inclined surface, making it difficult for water droplets and dust to accumulate on the inclined surface. Note that a minor angle is an angle smaller than 180 degrees.

[0020] Furthermore, the three-dimensional covering portion has a substantially smooth upright surface that is continuous with one end of the inclined surface at an acute angle, which prevents water droplets and dust from entering the protective cover from the boundary between the upright surface and the inclined surface, thereby preventing deterioration of the attached machine due to wind, rain, dust, sunlight, etc.

[0021] Furthermore, the substantially smooth vertical surface that is provided continuous with one end of the inclined surface at an acute angle allows water droplets and dust that fall onto the three-dimensional covering portion to quickly fall down along the inclined surface and vertical surface without remaining on the three-dimensional covering portion, thereby providing good drainage and dust removal properties.

[0022] Furthermore, the side covering portion is continuous with the inclined surface and has a substantially smooth continuous inclined surface in at least a portion thereof, so that no gaps are formed between the inclined surface and the continuous inclined surface through which wind, rain, and dust can penetrate, thereby suppressing the penetration of wind, rain, and dust, thereby preventing deterioration of the aircraft to which the installation is made.

[0023] Furthermore, the side covering portion has at least a portion of a substantially smooth, continuous inclined surface that is provided at an angle greater than the angle of inclination of the inclined surface, which allows water droplets and dust that fall onto the inclined surface to slide down with even more force and fall more easily outside the operator portion, thereby providing good drainage and dust removal properties.

[0024] Furthermore, when the continuous inclined surface is composed of a first continuous inclined surface having a predetermined area and being continuous with the first inclined surface at a minor angle, and a second continuous inclined surface having a predetermined area and being continuous with the second inclined surface at a minor angle, and being continuous with the first continuous inclined surface at a minor angle so that the boundary area with the first continuous inclined surface bulges outward, water droplets and dust that fall onto the first inclined surface will fall along the first continuous inclined surface, and water droplets and dust that fall onto the second inclined surface will fall along the second continuous inclined surface, so that water droplets and dust on the first continuous inclined surface and the second continuous inclined surface can be made to fall separately, preventing water droplets and dust from collecting and accumulating in one place.

[0025] Furthermore, when the inclination angle of the first inclined surface and the second inclined surface is between 30 degrees and 60 degrees, water droplets and dust that fall onto the inclined surface are less likely to remain on the inclined surface, but are more likely to slide down the inclined surface at a predetermined speed and fall outside the operator section, thereby providing good drainage and dust removal properties.

[0026] Furthermore, if the inclination angle is gentler than 30 degrees, the speed at which water droplets and dust that fall onto the inclined surface move will not increase, and there is a risk that the water droplets and dust will remain on the inclined surface, making it difficult to provide good drainage and dust removal properties.

[0027] Furthermore, when the inclination angle is steeper than 60 degrees, the speed of water droplets and dust falling onto the inclined surface increases, making it easier for the water droplets and dust to slide down the inclined surface without remaining on the surface. However, when the inclined surface approaches the driver's seat and its bottom edge is positioned above the driver's seat, the protective sheet bends on the seat, so the water droplets and dust that slide down the inclined surface may remain on the seat after sliding down the inclined surface. This causes the protective cover to sink on the seat due to the weight of the water droplets, etc., and the bottom of the protective cover is rolled up and exposed, making it difficult to provide good drainage and dust removal capabilities.

[0028] Furthermore, when the inclination angle of the first continuous inclined surface and the second continuous inclined surface is between 40 degrees and 90 degrees, water droplets and dust sliding down the inclined surface will increase in speed and slide down the first continuous inclined surface and the second continuous inclined surface, making it easier for them to fall outside the operator section, thereby providing good drainage and dust removal properties.

[0029] Furthermore, if the inclination angle is gentler than 40 degrees, the speed at which water droplets and dust that fall onto the inclined surface slide down will not increase, and they may not be able to slide down the first continuous inclined surface and the second continuous inclined surface sufficiently, making it difficult to provide good drainage and dust removal properties.

[0030] Furthermore, if the inclination angle exceeds 90 degrees, water droplets and dust particles that fall onto the inclined surface may fall down the first and second continuous inclined surfaces and accumulate on the floor near the operator's seat and operating equipment, making it difficult to achieve good drainage and dust removal properties.

[0031] Furthermore, if the protective cover has an attachment portion that extends from the bottom of the side covering portion and can be attached to the target aircraft, when attaching the protective cover to the target aircraft, the side covering portion can be easily attached to the target aircraft by pulling the attachment portion that extends from the side covering portion without pulling the side covering portion excessively forward.

[0032] Furthermore, the attachment portion that extends from the bottom of the side covering portion and can be attached to the aircraft to which it is to be attached not only makes it easy to attach and detach the protective cover using the attachment portion, but also prevents the protective cover from coming off the aircraft to which it is to be attached.

[0033] Furthermore, a continuous inclined surface can be formed from the inclined surface to the continuous inclined surface by the attachment part that extends from the bottom of the side covering part and can be attached to the machine body to which it is attached. This makes it easier for water droplets and dust that fall on the inclined surface and the continuous inclined surface to slide down the continuous inclined surface from the inclined surface to the continuous inclined surface and fall outside the operator part, thereby providing good drainage and dust removal properties.

[0034] Furthermore, if the mounting portion is provided with a predetermined number of magnetic bodies that can be magnetically attached to the target aircraft, the side covering portion can be easily attached to the target aircraft by magnetically attaching the magnetic bodies to the target aircraft.

[0035] Furthermore, if a predetermined number of magnetic bodies that can be magnetically attached to the target machine body are provided at the lower end of the erected surface, the erected surface can be easily attached to the target machine body by magnetically attaching the magnetic bodies to the target machine body.

[0036] Furthermore, in order to solve the above-mentioned problems, the method for attaching a protective cover of the present invention includes an insertion step of inserting an object to be attached into the interior of the protective cover, the object to be attached being attached from the open end side of the side covering part, from the other open end side of the side covering part, the protective cover including a hollow three-dimensional covering part formed in a three-dimensional shape, the hollow three-dimensional covering part having an inclined surface formed so that the approximately central region bulges outward and has one end continuous with the three-dimensional covering part and the other end open, and at least a portion of which is continuous with the inclined surface and has an inclination angle greater than the inclination angle of the inclined surface; and an attachment step of, after the insertion step, stretching the protective cover from the inclined surface to the continuous inclined surface and attaching it to the object to be attached.

[0037] Here, a protective cover having a hollow three-dimensional covering portion formed in a three-dimensional shape and a side covering portion having one end continuous with the three-dimensional covering portion and the other end open can provide a space within the protective cover that can contain the aircraft to be attached.

[0038] In addition, the inclined surface, which has a predetermined area and a predetermined inclination angle, allows water droplets and dust that fall onto the inclined surface to slide down quickly, thereby providing good drainage and dust removal properties.

[0039] In addition, the inclined surface is formed so that the approximately central area bulges outward, so that water droplets and dust that fall onto the inclined surface separate from the bulging area and slide down, thereby providing good drainage and dust removal properties.

[0040] Furthermore, the side covering portion has at least a portion of a continuous inclined surface that is continuous with the inclined surface and has an inclination angle that is greater than the inclination angle of the inclined surface, which allows water droplets and dust that fall onto the inclined surface to slide down with even more force and fall outside the operator portion, thereby providing good drainage and dust removal properties.

[0041] Furthermore, by means of an insertion process in which the object to be attached is inserted into the protective cover from the other open end of the side covering portion, the object to be attached can be enclosed and shielded from wind, rain, and sunlight, thereby suppressing deterioration of the object to be attached due to wind, rain, dust, sunlight, etc.

[0042] Furthermore, after the insertion step, the protective cover is tensioned from the inclined surface to the continuous inclined surface and attached to the target aircraft in the attachment step, whereby the protective cover can be attached to the target aircraft while maintaining the state in which an inclined surface with a predetermined tension is formed from the inclined surface to the continuous inclined surface. This makes it difficult for water droplets and dust to accumulate in the bent parts of the protective cover, and provides good drainage and dust removal properties.

[0043] Furthermore, the above-described mounting process allows water droplets and dust particles that fall onto the inclined surface to slide down the inclined surface in one go and fall outside the operator section, thereby providing good drainage and dust removal properties. [Effects of the Invention]

[0044] The protective cover and protective cover installation method according to the present invention protect the driver's seat and its peripheral equipment from getting wet, getting dirty, being damaged by pests and vermin, and being deteriorated by sunlight, and have good drainage and dust removal properties, and are easy to install and remove, yet do not easily come off the aircraft to which they are installed.

DETAILED DESCRIPTION OF THE INVENTION

[0046] The protective cover A of the present invention will be described below with reference to Figures 1 to 5 to facilitate understanding of the present invention. Note that the terms "front (side)," "rear (side)," "right (side)," "left (side)," "upper (side)," and "lower (side)" used in this specification refer to the front-to-rear direction, left-to-right direction, and up-down direction when seated in the driver's seat.

[0047] [First embodiment] As shown in FIGS. 1 and 2, the protective cover A has a generally cylindrical shape with a closed top and an open bottom, and is formed to a size that allows it to cover an operator section M2, which will be described later.

[0048] The protective cover A is formed from a continuous fabric body A0 and is composed of a three-dimensional covering part 2 that can cover the upper part of the aircraft to which it is attached, and a side covering part 3 that is continuous with the three-dimensional covering part 2 and has an open bottom. The lower edge of the side covering part 3 is referred to as the opening edge part 1.

[0049] Furthermore, the protective cover A is tensioned with a predetermined tension without being folded or bending, resulting in a three-dimensional shape with a substantially smooth surface without any irregularities. The fabric body A0 is made of polyester canvas No. 6, which is suitable for long-term use. While other materials such as tarpaulin and Ultramax (registered trademark) could be used, polyester canvas No. 6 is preferable in terms of cost, weight, workability, and durability.

[0050] Furthermore, in this embodiment, the protective cover A has the three-dimensional covering portion 2 and the side covering portion 3 provided continuously, but this is not limited to this. For example, it is conceivable to prepare the three-dimensional covering portion 2 and the side covering portion 3 as separate fabric bodies and connect them using known attachment means such as hook-and-loop fasteners, snap buttons, or stitching. However, it is conceivable that water droplets or dust may enter through the joint and wet the operator portion M2, or that wind may enter through the joint and cause the protective cover to detach from the aircraft body. For this reason, it is desirable to form them as a continuous fabric body in order to prevent the intrusion of water droplets and dust.

[0051] 3, a machine body M of a heavy machine (excavator), which is an example of a machine body to which the protective cover A is attached, has a cab room M1 provided on a rotating body M0, and a driver's seat M20 and an operating device M21 (hereinafter referred to as "operator section M2") arranged around the driver's seat M20 are installed inside the cab room M1. The machine body M is a so-called canopy-type machine body, and includes a roof section M22 located above the driver's seat M20, and four columns supporting the roof section M22: a right rear support column M3a, a left rear support column M3b, a right front support column M3c, and a left front support column M3d.

[0052] The protective cover A is formed so that it can enclose and cover the upper part of the operator part M2 with the three-dimensional covering part 2, and can also enclose and cover the lower part of the operator part M2 with the side covering part 3. Note that the protective cover A described in this embodiment does not enclose the maintenance box M4 described below, but this is not limited to this, and the protective cover may be formed so that it can enclose the maintenance box M4.

[0053] The three-dimensional covering part 2 located on top of the protective cover A is formed in the shape of a substantially inverted triangular prism and is configured to be able to cover the front side to the top of the operator part M2. That is, the three-dimensional covering part 2 is composed of an inclined surface 20 having an inclination angle of approximately 40 degrees, an upright surface 21 that is arranged in a substantially vertical direction and is able to cover the rear side of the operator part M2, and side surfaces 22a, 22b that are arranged in a substantially vertical direction and close both side surfaces of the three-dimensional body formed by the inclined surface 20 and the upright surface 21. The protective cover A, which is composed of the three-dimensional covering part 2 and the side surface covering part 3, is formed to be large enough to accommodate the operator part M2 inside.

[0054] The structure of the three-dimensional covering portion is not limited to the above, and the three-dimensional covering portion may be formed, for example, in the shape of a substantially inverted square prism or a hemisphere. However, when taking into consideration the good drainage properties of the three-dimensional covering portion, it is desirable to have a structure in which an inclined surface provided at a predetermined angle and an upright surface provided approximately vertically are continuous.

[0055] Furthermore, the erected surface is not limited to being provided in a substantially vertical direction, and may be, for example, inclined forward at a predetermined angle. However, in this case, it is desirable to provide the erected surface in a substantially vertical direction, since water droplets and the like can slide down a vertical surface more quickly than if they were to slide down an inclined surface.

[0056] Furthermore, the position of the standing surface is not limited to the rear of the operator unit M2. For example, it is possible to provide the standing surface in front of the operator unit M2 with a slope extending from the upper front to the lower rear. However, in this case, the slope may be provided at a gentle angle to prevent the top of the driver's seat M20 from contacting the slope, which makes it difficult to maintain good drainage and dust control. Therefore, when good drainage and other factors are taken into consideration, it is preferable to provide the standing surface behind the operator unit M2.

[0057] In addition, the inclined surface 20 is formed in an approximately pentagonal shape and consists of an upper edge 20a located at the upper end of the top covering part 2, a right edge 20b connecting the right end E1 of the upper edge 20a and a contact point P1 that contacts the monitor M5 of the operator part 2 (see Figures 3 to 6), a lower edge 20c connecting the contact point P1 and a contact point P2 that contacts the tip of the lever M6 of the operator part 2 (see Figure 3), a hypotenuse 20d connecting the contact point P2 and a contact point P3 that contacts the corner of the handrail M7 of the operator part 2 (see Figure 3), and a left edge 20e connecting the hypotenuse 20d and the left end E2 of the upper edge 20a.

[0058] The inclined surface 20 is composed of an inclined triangular surface 20A, which is a triangle formed by connecting the right end E1, the tangent point P1, and the tangent point P2, and an inclined quadrilateral surface 20B, which is a quadrilateral formed by connecting the right end E1, the tangent point P2, the tangent point P3, and the left end E2. The inclined triangular surface 20A corresponds to the first inclined surface, and the inclined quadrilateral surface 20B corresponds to the second inclined surface.

[0059] In this embodiment, the inclined triangular surface 20A and the inclined rectangular surface 20B are not flush, but are continuous with each other at a minor angle, with boundary region 20C bulging outward. This allows water droplets and dust falling onto the inclined surface to slide down, splitting between inclined triangular surface 20A and inclined triangular surface 20B, making it difficult for water droplets and dust to accumulate on the inclined surface.

[0060] The shape of the inclined surface is not limited to this, and the inclined triangular surface and the inclined square surface may be arranged so as to be flush, but as will be described later, water droplets or dust falling onto the inclined surface will be separated onto the inclined triangular surface and the inclined square surface, slide down and fall outside the operator section, improving drainage and dust removal, so it is preferable to have a structure in which the inclined triangular surface and the inclined square surface are continuous with each other at a minor angle.

[0061] Furthermore, in this embodiment, the boundary region 20C where the inclined triangular surface 20A and the inclined square surface 20B meet is formed so as to bulge outward and protrude like a mountain, but this is not limited to this and it is also possible to form it so as to sink like a valley. If it is formed like a valley, water droplets that fall on the inclined triangular surface and the inclined square surface will collect at the bottom of the valley, and there is a risk that the protective cover will roll up due to the weight and become detached from the machine body M. Therefore, when considering good drainage performance, etc., it is desirable to have a structure where the inclined triangular surface 20A and the inclined square surface 20B meet so as to protrude like a mountain.

[0062] The inclined surface 20 is continuous with the standing surface 21 at the top of the three-dimensional covering portion 2, forming a ridge portion 23 (corresponding to the upper side 20a). The inclined surface 20 and the standing surface 21 do not necessarily need to be continuous via the ridge portion 23, but may be continuous via a strip-shaped portion having a predetermined width, a curved portion, or the like.

[0063] That is, the inclined rectangular surface 20B is provided at an inclination angle of about 40 degrees with the ridge 23 as its apex so as to be able to cover the area from approximately the center of the front side of the operator part M2 to the left side from the ridge 23. Also, the inclined triangular surface 20A is provided at an inclination angle of about 40 degrees along the right side 20b of the inclined surface 20 so as to be able to cover the area from approximately the center of the front side of the operator part M2 to the right side.

[0064] The erected surface 21 is provided in a substantially vertical direction so as to be able to cover the area from the ridge 23 to the rear side of the operator unit M2. The erected surface 21 is not continuous with the side covering unit 3, but this is not limitative and it is also possible to configure the erected surface 21 to be continuous with the side covering unit 3.

[0065] The side covering part 3 is configured to be able to cover the lower area of ​​the operator part M2 from the front to both side surfaces. That is, it is composed of a front covering part 31 that is continuous with the inclined triangular surface 20A and is able to cover the front area of ​​the lower part of the operator part M2, a right side covering part 32 that is continuous with the side surface 22a and is able to cover the right area of ​​the lower part of the operator part M2, a front covering part 33 that is diagonally left and is continuous with the inclined rectangular surface 20B and is able to cover the front left diagonal area of ​​the lower part of the operator part M2, and a left side covering part 34 that is continuous with the side surface 22b and is able to cover the left side of the lower part of the operator part M2.

[0066] The front surface covering portion 31 and the left-side front surface covering portion 33 are provided at an angle steeper than the inclined surface 20, which in this embodiment is an angle of about 65 degrees. The right side surface covering portion 32 and the left side surface covering portion 34 are provided in a substantially vertical direction.

[0067] Moreover, the side covering portion 3 has a shape that widens slightly toward the bottom 30. For this reason, when the side covering portion 3 is pulled forward (outward) so as to contact the front magnetized portion M9a of the machine body M, the fabric body M0 near the bottom 30 of the front covering portion 31 becomes slightly pointed toward the front (outward), and the fabric bodies A0 near the bottom 30 of the right side covering portion 32, the left front covering portion 33, and the left side covering portion 34 approach the driver's seat M20, so they have a slightly tapered shape going from the rear to the front.

[0068] A band-shaped front mounting portion 24 having a predetermined width, which is an example of a mounting portion, extends outward from the bottom 30 of the front covering portion 31. Front magnetic bodies 24a, 24b are provided at both ends of the front mounting portion 24, allowing it to be magnetically attached to the front magnetically attached portion M9a (see Figures 3 and 5) of the machine body M. In other words, by pulling the front mounting portion 24 forward (outward), the front covering portion 31 of the side covering portion 3 can be tensioned so that tension is applied to it. While hook-and-loop fasteners, snap buttons, or side release buckles could be substituted for the magnetic bodies, magnetic bodies are preferred for ease of attachment and removal. The number of magnetic bodies provided on the front mounting portion 24 is not limited to two and can be any number.

[0069] Furthermore, the front mounting portion 24 is attached to the outer surface of the front magnetized portion M9a beyond the front magnetized portion M9a. This causes water droplets and dust sliding down the front cover 31 to fall outside the operator portion M2 without falling onto the floor M8 of the operator portion M2. This prevents the floor M8 from getting wet or dirty, thereby improving drainage and dust removal.

[0070] The mounting method is not limited to the above, and the front mounting part 24 can also be mounted inside the front magnetized part M9a. However, since water droplets and dust will fall onto the floor M8 of the operator part M2, making the floor M8 wet or dirty, making it difficult to maintain drainage and dust removal, it is preferable to mount the front mounting part 24 outside the front magnetized part M9a.

[0071] At this time, as the front surface covering portion 31 is tensioned, tension is also applied to the inclined triangular surface 20A that is continuous with the front surface covering portion 31, so that the inclined triangular surface 20A is tensioned. As a result, a water sliding surface 4A that is continuous from the inclined triangular surface 20A to the front surface covering portion 31 is formed.

[0072] Furthermore, at the same time that the front surface covering portion 31 is tensioned, tension is also applied to the left-side front surface covering portion 33, which is continuous with the front surface covering portion 31, and the inclined square surface 20B, which is continuous with the left-side front surface covering portion 33, so that the inclined square surface 20B is tensioned. As a result, a water sliding surface 4B is formed that is continuous from the inclined square surface 20B to the left-side front surface covering portion 33.

[0073] In addition, water droplets that fall on the inclined triangular surface 20A slide down the inclined triangular surface 20A, which has an inclination angle of approximately 40 degrees, and then slide down the front covering portion 31, which has an inclination angle of approximately 65 degrees, and fall outside the cab compartment M1.

[0074] Furthermore, water droplets that fall onto the inclined square surface 20B slide down the inclined square surface 20B, which has an inclination angle of approximately 40 degrees, and then slide down the left-side front surface covering portion 33, which has an inclination angle of approximately 65 degrees, and fall onto the edge M80 of the floor surface M8.

[0075] Furthermore, because the water sliding surfaces 4A, 4B are tensioned with a predetermined tension, the fabric body A0 is unlikely to bend, and water droplets that fall onto the water sliding surfaces 4A, 4B slide down with force without remaining on the surfaces 4A, 4B. This prevents water from accumulating on the protective cover A, preventing the protective cover A from sinking due to the weight of the water and becoming detached from the machine body M.

[0076] Furthermore, in this embodiment, the inclination angle of the inclined surface 20 is approximately 40 degrees, but this is not limited to this, and the inclination angle of the inclined surface can be set within the range of 30 to 60 degrees. In other words, by setting the inclination angle to 30 to 60 degrees, water droplets and dust that fall onto the inclined surface are less likely to remain on the inclined surface, but are more likely to slide down the inclined surface at a predetermined speed and fall outside the operator section, thereby providing good drainage and dust removal properties.

[0077] Furthermore, if the inclination angle is gentler than 30 degrees, the speed at which water droplets and dust that fall onto the inclined surface move will not increase, and there is a risk that the water droplets and dust will remain on the inclined surface, making it difficult to provide good drainage and dust removal properties.

[0078] Furthermore, when the inclination angle is steeper than 60 degrees, the speed of water droplets and dust falling onto the inclined surface increases, making it easier for the water droplets and dust to slide down the inclined surface without remaining on the surface. However, when the inclined surface approaches the driver's seat and its bottom edge is positioned above the driver's seat, the protective sheet bends on the seat, so the water droplets and dust that slide down the inclined surface may remain on the seat after sliding down the inclined surface. This causes the protective cover to sink on the seat due to the weight of the water droplets, etc., and the bottom of the protective cover is rolled up and exposed, making it difficult to provide good drainage and dust removal capabilities.

[0079] In this embodiment, the inclination angle of the front surface covering part 31 and the left-side front surface covering part 33 is set to approximately 65 degrees, but it is also possible to consider setting it to a range of 40 degrees to 90 degrees. In other words, in this case, water droplets and dust that have slid down the inclined surface 20 will further increase their speed and slide down the front surface covering part 31 and the left-side front surface covering part 33, making them more likely to fall outside the operator section, thereby providing good drainage and dust removal properties.

[0080] Furthermore, if the inclination angle is gentler than 40 degrees, the speed at which water droplets and dust that fall onto the inclined surface 20 slide down will not increase, and there is a risk that they will not be able to slide down sufficiently on the front covering portion 31 and the left-side front covering portion 33, making it difficult to provide good drainage and dust removal properties.

[0081] Furthermore, if the inclination angle exceeds 90 degrees, water droplets and dust particles that fall onto the inclined surface 20 may fall along the front covering portion 31 and the left-side front covering portion 33 and accumulate on the floor surface M8 near the driver's seat M20 of the operator section M2 and the operating equipment M21, making it difficult to achieve good drainage and dust removal properties.

[0082] Further, right magnetic bodies 32a and 32b are provided on the right side surface covering portion 32. In this embodiment, the front region of the right side surface covering portion 32 is attached upside down so that the right magnetic body 32a is magnetically attached to the maintenance box M4. This prevents the right side surface covering portion 32 from being detached from the vehicle M due to wind blowing between the maintenance box M4 and the cab compartment M1. Note that, depending on the vehicle, it may be possible to design the right side surface covering portion 32 so that the right magnetic body 32a can be magnetically attached to the cab compartment M1 without having to turn the front region of the right side surface covering portion 32 upside down.

[0083] Furthermore, left magnetic bodies 34a and 34b are provided near the lower rear end of the left side surface covering part 34. The left magnetic bodies 34a and 34b are magnetically attached to the rear left side surface of the machine body M. This makes it possible to prevent the left side surface covering part 34 from becoming detached from the machine body M due to wind blowing from the rear left of the machine body M.

[0084] Furthermore, the right side surface 22a of the three-dimensional covering portion 2 and the right side surface covering portion 32 are connected to form the water drop surface 5A, and the left side surface 22b and the left side surface covering portion 34 are connected to form the water drop surface 5B. In other words, the water drop surfaces 5A and 5B are provided in a substantially vertical direction, and water droplets that land on the water drop surfaces 5A and 5B do not stay on the water but slide down vigorously on the water drop surfaces 5A and 5B.

[0085] Specifically, water droplets and dust that slide down the water drop surface 5A pass between the maintenance box M4 and the cab room M1 and are discharged outside the machine body M. Furthermore, water droplets and dust that slide down on the water drop surface 5B are directly discharged outside the machine body M because the left side cover part 34 is attached along the outer shape of the machine body M. In this way, water droplets and dust are prevented from accumulating on the protective cover A, and the protective cover A can have good drainage and dust removal properties.

[0086] Furthermore, the standing surface 21 is provided with a predetermined tension in the approximately vertical direction, so that water droplets that land on the standing surface 21 do not remain but slide down vigorously on the standing surface 21. This prevents water droplets and dust from accumulating on the standing surface 21. In other words, the protective cover A, which is made up of the water sliding surfaces 4A, 4B, the water dropping surfaces 5A, 5B, and the standing surface 21, has good drainage and dust resistance.

[0087] A strip-shaped rear mounting portion 25 having a predetermined width extends outward from the lower end portion 210 of the standing surface 21. Rear magnetic bodies 25a, 25b, and 25c are provided at both ends of the rear mounting portion 25, and the rear mounting portion 25 can be magnetically attached to the rear magnetically attached portion M9b (see FIG. 4) of the machine body M and attached thereto. By pulling the rear mounting portion 25 downward and magnetically attaching it to the machine body M, tension can be applied to the standing surface 21 to make it stretched. Note that while it is conceivable to provide the rear mounting portion 25 extending toward the inside of the protective cover A, it is desirable to attach the rear mounting portion 25 facing outward because water droplets and dust may enter the protective cover A along the rear mounting portion 25. Note that the number of magnetic bodies provided on the rear mounting portion 25 is not limited to three and can be any number.

[0088] Additionally, grommets 26, 26 are provided on both sides of the upper part of the three-dimensional covering portion 2, and mounting arms 6, 6 extend from the grommets 26, 26, respectively. The mounting arms 6, 6 are made up of connecting carabiners 60, 60 which are connecting members for connecting to the grommets 26, 26, bands 61, 61 connected to the carabiners 60, 60 and formed to a predetermined length, and mounting carabiners 62, 62 attached to the tip ends of the bands 61, 61.

[0089] The mounting arms 6, 6 are mounting members for mounting the protective cover A to the canopy portion M22 of the operator portion M2, and the mounting method will be described later. Note that the mounting arms are not limited to the above structure, and it is also possible to use a chain or rope instead of the belt or carabiner.

[0090] Since the operator unit 2 is covered by the protective cover A having the above-described configuration, it is possible to prevent the driver's seat M20 of the operator unit 2 and the operating equipment M21 from getting wet or dirty due to water droplets or dust adhering thereto, or to prevent deterioration of the driver's seat etc. due to sunlight.

[0091] Furthermore, since the protective cover A is formed three-dimensionally from a continuous fabric body A0, the protective cover A can be easily attached to the machine body M by simply placing the protective cover A over the operator section M2.

[0092] Furthermore, the fabric body A0 of the protective cover A is stretched without being folded and without bending, so there are no overlapping parts of the fabric body A0, and the protective cover A has a three-dimensional shape with no unevenness overall. This prevents wind from blowing into the folded parts and causing the protective cover A to detach from the machine body M, and prevents water droplets from accumulating in the folded parts and causing the protective cover to detach from the machine body M due to the weight of the water droplets.

[0093] Furthermore, by simply placing the protective cover A over the operator part M2, magnetically attaching the front mounting part 24 to the front magnetized part M9a and magnetically attaching the rear mounting part 25 to the rear magnetized part M9b, not only can the protective cover A be easily attached to and detached from the machine body M, but the protective cover A can also be prevented from coming off the machine body M.

[0094] The protective cover A can be formed to fit the shape of the machine body M, and is not limited to the shape of this embodiment. It is also possible to change it as needed to fit the shape of the machine body.

[0095] Additionally, the hems 30 of the front covering portion 31, right side covering portion 32, left-side front covering portion 33, and left side covering portion 34 are provided with folded-over portions 36 formed by doubling up the edges of the fabric body A0, and a string-like body (not shown) of a predetermined thickness is inserted into this folded-over portion. This reinforces the entire protective cover A, preventing tearing of the protective cover A due to the tensile forces applied to the protective cover A from various directions when the protective cover A is stretched and attached to the aircraft body M. The material of the string-like body is not particularly limited, but polyester is preferred. This is because it is resistant to acids, alkalis, seawater, etc., has excellent weather resistance, is highly resistant to friction, and is strong.

[0096] Furthermore, the protective cover A can also be folded and stored when the vehicle M is in operation. That is, first, the right side covering portion 32 of the side covering portion 3 is folded toward the center, and then the left front covering portion 33 and the left side covering portion 34 are folded toward the center. Then, by folding the front covering portion 31 toward the three-dimensional covering portion 2 to a width approximately equal to the width of the seat, the protective cover A can be stored compactly, for example, by placing it behind the driver's seat M20 (not shown). Note that the protective cover A is not limited to the above folding method as long as it can be folded compactly.

[0097] [Second embodiment] A protective cover according to a second embodiment (hereinafter simply referred to as the "second protective cover") will be described below. Note that the configuration of the second embodiment is the same as that of the first embodiment, and the same parts are denoted by the same reference numerals, and the description thereof will be omitted here.

[0098] On the inclined surface of the second protective cover, the contact points P1, P2, and P3 of the first embodiment are positioned so as to be aligned substantially on the same straight line in a plan view.

[0099] Here, water droplets and dust that fall onto the inclined surface slide down the inclined surface, run along the side covering portion, drip onto the floor surface M8, and are discharged outside the operator unit M2. Note that the inclined surface of this embodiment is formed in a substantially trapezoidal shape that widens from the top edge to the bottom edge, so that water droplets that fall onto the inclined surface can be efficiently drained.

[0100] [Third embodiment] A protective cover according to a third embodiment (hereinafter simply referred to as the "third protective cover") will be described below. Note that the configuration of the third embodiment is the same as that of the first embodiment, and the same parts are denoted by the same reference numerals, and the description thereof will be omitted here.

[0101] The inclined surface of the third protective cover consists of a rectangular inclined rectangular surface formed by connecting the right end E1, left end E2, and contact points P1 and P2 of the upper edge 20a of the first embodiment, and a triangular inclined triangular surface formed by connecting the left end E2 and contact points P2 and P3.

[0102] As a result, water droplets and dust particles that fall onto the inclined surfaces of the third protective cover are separated and slide down onto the inclined square surfaces and inclined triangular surfaces, making it difficult for water droplets and dust particles to accumulate on the inclined surfaces.

[0103] [Installation method of protective cover A, second protective cover, and third protective cover] First, the method of attaching the protective cover A will be described with reference to Fig. 7. The second and third protective covers are attached in the same manner as the protective cover A, except that the shapes of the inclined surfaces are different.

[0104] [Insertion process (ST01)] First, the operator unit M2 of the machine body M is inserted through the opening edge 1 of the protective cover A to cover it. The protective cover A is formed to a size that can contain the operator unit M2, so the operator unit M2 can be covered simply by placing the protective cover A over the operator unit M2. This prevents the driver's seat M20 of the operator unit 2 and the operating equipment M21 from getting wet or dirty due to water droplets or dust adhering to them, or the driver's seat and other components from being deteriorated by sunlight.

[0105] [Installation process (ST02)] After the operator part M2 is covered with the protective cover A, the front attachment part 24 provided at the bottom part 30 of the front area 31 is attached to the front magnetized part M9a of the operator part M2. Next, the rear attachment part 25 provided at the lower end part 210 of the standing surface 21 is attached to the rear magnetized part M9b of the operator part M2.

[0106] At this time, the front magnetic bodies 24a, 24b of the front mounting portion 24 are magnetically attracted to the front magnetically attracted portion 9a, and the rear magnetic bodies 25a, 25b, 25c of the rear mounting portion 25 are magnetically attracted to the rear magnetically attracted portion M9b. This makes it difficult for the protective cover A to easily detach from the machine body M. Furthermore, because the water sliding surfaces 4A, 4B and the standing surface 21 are tensioned with a predetermined degree of tension, water droplets and dust that fall onto the water sliding surfaces 4A, 4B slide down and fall on the water sliding surfaces 4A, 4B, allowing them to be efficiently drained.

[0107] [Hanging process (ST03)] Carabiners 62, 62 attached to the tips of mounting arms 6, 6 attached to both sides of the upper part of the three-dimensional section 2 of the protective cover A are hung on hanging portions M23, M23 attached to the eaves section M22 of the operator section M2 of the machine body M. This not only allows the protective cover A to be attached in a suspended state from the eaves section M22, but also provides greater tension to the water sliding surface 4A formed from the ridge section 23 of the three-dimensional covering section 2 to the front covering section 31, and to the water sliding surface 4B formed from the inclined square surface 20B to the left-side front covering section 33, resulting in a protective cover A with even better drainage and dust removal properties.

[0108] In this way, the protective cover to which the present invention is applied protects the driver's seat and its peripheral equipment from getting wet, getting dirty, being damaged by pests and vermin, and being deteriorated by sunlight, and has good drainage and dust removal properties, and is easy to attach and remove, yet does not easily come off the aircraft to which it is attached.
