Description

Technical Field

[0001] The present invention relates to a protective cover for covering and protecting the driver's seat provided in a machine body such as a heavy machine and its surroundings, and a method for attaching the protective cover. Specifically, the present invention relates to a protective cover that prevents the driver's seat and its peripheral devices from getting wet, dirty, and deteriorating due to sunlight, and is easy to attach and remove, yet difficult to detach from the machine body to which it is attached, and a method for attaching the protective cover.

Background Art

[0002] Heavy machines used outdoors include a "cab type" in which the driver's seat is provided inside a box-shaped cab, and a "canopy type" in which only a roof portion provided above the driver's seat and two support columns supporting it are provided, and there is no partition member surrounding the driver's seat and its peripheral devices (hereinafter referred to as the "operator section"), and the operator section is exposed.

[0003] In the case of the cab type, since the surroundings are surrounded by partition members, the operator section is not exposed to sunlight, rain, or wind, so the deterioration of the driver's seat and the like progresses slowly.

[0004] On the other hand, in the case of the canopy type, since there is no partition outside the operator section except for the roof portion, the operator section has an exposed structure, and the operator section is directly affected by sunlight, wind, and rain. Not only does the seat surface and equipment get wet and dirty, but also the surface fabric of the driver's seat and the surface coating of the peripheral equipment crack and peel due to sunlight, etc., or the performance of the equipment itself is affected by wetness and dirt, etc., and the deterioration progresses significantly in terms of quality and function. Also, during the construction period, heavy machines often wait at the site, and in this case, since they are constantly exposed to the outside air, the temperature change between day and night also has an impact, and the deterioration of the operator section tends to progress more rapidly in a short period of time.

[0005] To solve this problem, as disclosed in Patent Document 1, there is disclosed a "protective cover for construction machinery and its usage method" that covers and protects the area from the front part to the operator part of a construction machinery with a canopy specification with a sheet-shaped protective cover. This protective cover for construction machinery has a sheet shape, and uses attachment pieces etc. to fix the front side part and the rear side part of the protective cover with fixing ropes, and further suspends the upper surface of the protective cover from the eaves part and fixes it to the machine body, thereby covering the operator part of the machine body.

[0006] Also, as disclosed in Patent Document 2, there is disclosed a "protective cover for construction machinery" that covers and protects the area from the front part to the operator part of a construction machinery with a canopy specification with a three-dimensionally formed protective cover. This protective cover for construction machinery attaches a fixing rope to the lower end of the protective cover, tightens and fixes it in the horizontal direction, and further suspends the upper surface of the protective cover from the eaves part and fixes it to the machine body, thereby covering the operator part of the machine body.

Summary of the Invention

Problems to be Solved by the Invention

[0008] However, since the protective cover described in Patent Document 1 is formed in a sheet shape, it is necessary to use fixing ropes to stretch the protective cover in the front and rear directions respectively to conform the sheet-shaped protective cover to the shape of the machine body, and further suspend the upper surface of the protective cover from the eaves part and fix it to the machine body, which is very time-consuming for the attachment and removal work.

[0009] In addition, although the protective cover described in Patent Document 2 is three-dimensionally formed, the hem portion must be fastened to the aircraft body with a fixing rope and further fixed to the aircraft body by suspending it from the eaves portion. Similar to the protective cover described in Patent Document 1, the attachment / detachment work is time-consuming.

[0010] That is, although both Patent Document 1 and Patent Document 2 can protect the driver's seat and the like from deterioration, they do not solve the problem of being time-consuming for attachment / detachment.

[0011] The present invention was devised in view of the above points, and an object thereof is to provide a protective cover that protects the driver's seat and its peripheral devices from wetting, soiling, and deterioration due to sunlight, and is easy to attach and detach while being difficult to separate from the attachment target aircraft body.

Means for Solving the Problems

[0012] In order to solve the above problems, the protective cover of the present invention is a substantially cylindrical protective cover having an opening, a top region substantially opposite to the opening, and a side region continuously provided from the opening to the top region, and is provided in a region covering the vicinity of the top region of the side region, the vicinity of the side region of the top region, or both the side region and the top region, has a predetermined diameter, and has two through-holes communicating with the opening, and is continuously extended from between the two through-holes in a direction opposite to the top region and continuous with the top region, forming a part of the side region. A first covering portion, a second covering portion continuously provided with the top region and forming the side region together with the first covering portion, and one end portion in the circumferential direction of the first covering portion and one end portion of the second covering portion close to the one end portion, and the other end portion in the circumferential direction of the first covering portion and the other end portion of the second covering portion close to the other end portion. And a connecting portion capable of connecting the other end portions.

[0013] Here, by being a substantially cylindrical protective cover having an opening, a top region substantially facing the opening, and a side region continuously provided from the opening to the top region, the object to be mounted can be enclosed within the protective cover to block wind, rain, and sunlight, so that deterioration of the object to be mounted due to wind, rain, sunlight, etc. can be suppressed.

[0014] Also, due to the through-holes provided in the region near the top region of the side region, the region near the side region of the top region, or the region covering both the side region and the top region, a predetermined length can be provided from the through-holes to the side region, so that the object to be mounted can be covered using the portion from the through-holes to the lower end of the side region.

[0015] Also, due to the through-holes having a predetermined diameter, a protrusion provided on the object to be mounted can be inserted into the through-holes, so that the generation of a gap between the surface of the object to be mounted and the protective cover can be suppressed, and it is possible to prevent the wind from entering and the protective cover from being peeled off from the machine body and detaching.

[0016] Also, due to the through-holes communicating with the opening, a protrusion provided on the object to be mounted can be inserted into the through-holes by inserting it from the opening, so that the protective cover can be covered along the object to be mounted while avoiding the protrusion. As a result, the generation of a gap between the surface of the object to be mounted and the protective cover can be suppressed, so that not only can the wind be prevented from entering and the protective cover from being peeled off from the machine body and detaching, but also the attachment and detachment of the protective cover can be easily performed.

[0017] Note that the protrusion may be, for example, a support column that supports an eaves portion provided on a canopy-type machine body, but is not limited thereto, and members protruding from the surface of the object to be mounted such as a handle, an antenna, and a mirror are also conceivable.

[0018] In addition, a first covering portion is continuously extended from between the two through-holes in a direction opposite to the top region and is continuous with the top region, forming a part of the side region, and a second covering portion is provided continuously with the top region and forms the side region together with the first covering portion. Thus, the entire side of the mounting target body can be covered. Since the side region of the protective cover is divided into two parts, the opening of the protective cover can be greatly expanded to the through-hole, and when enclosing the mounting target body, the operation can be easily performed.

[0019] Further, both covering portions can be connected by a connecting portion capable of connecting one end portion in the circumferential direction of the first covering portion and one end portion of the second covering portion close to the one end portion, and the other end portion in the circumferential direction of the first covering portion and the other end portion of the second covering portion close to the other end portion, so that the entire protective cover can be securely attached to the mounting target body. As a result, the two separated covering portions are closed, making it difficult for wind and rain to enter the protective cover, and preventing the protective cover from being peeled off and detached from the mounting target body. Also, since the attachment operation of the protective cover is completed only by connecting the two covering portions, the attachment operation of the protective cover can be easily performed.

[0020] Note that the mounting target body to which the protective cover is attached refers to an operator unit including a driver's seat and operating devices around it. Also, it is not necessarily limited to a body used outdoors, and includes bodies used indoors.

[0021] In addition, when it is inclined in a direction away from the top region from the lower end portion of the first covering portion to a part of the lower end portion of the second covering portion facing the lower end portion of the first covering portion, it can cover a part of the mounting target body deeply. Thus, for example, when it is desired to reliably protect the floor surface of the mounting target body, etc., the protective cover can be deeply covered on the mounting target body to reliably protect it from wind, rain, and sunlight. On the other hand, for a part of the mounting target body where the floor surface of the mounting target body is not provided, such as the rear part of the mounting target body, the attachment and detachment operations can be facilitated by covering it relatively shallowly.

[0022] In addition, when a folding portion capable of folding the second covering portion is provided near the circumferential end portion of the second covering portion, the second covering portion can be folded into a three-dimensional shape. As a result, the space inside the protective cover is expanded, and even if the positions and shapes of the operating devices of the aircraft to be attached are different depending on the model, they can be enclosed by the protective cover.

[0023] In addition, when a required number of dart portions are provided in the side surface region, the protective cover can be given a bulge to form a three-dimensional shape, so that it can be easily attached even if the shape of the aircraft to be attached has irregularities.

[0024] In addition, when a predetermined number of mounting holes are provided at both circumferential ends of the second covering portion, the two ends of the second covering portion can be pulled toward each other and attached by alternately passing a string-like body through the mounting holes at both ends. Therefore, the protective cover can be more reliably attached to the aircraft to be attached, and it is possible to prevent the protective cover from being easily peeled off and detached from the aircraft to be attached.

[0025] In addition, when a predetermined number of magnet bodies that can be magnetically attached to the aircraft to be attached are provided at both circumferential ends of the first covering portion, the first covering portion can be easily attached to the aircraft to be attached by magnetically attaching the magnet bodies to the aircraft to be attached.

[0026] In addition, when a predetermined number of magnet bodies that can be magnetically attached to the aircraft to be attached are provided at both circumferential ends of the second covering portion, the second covering portion can be easily attached to the aircraft to be attached by magnetically attaching the magnet bodies to the aircraft to be attached.

[0027] In addition, in order to solve the above problems, the protective cover of the present invention is a substantially cylindrical protective cover having an opening, a top region substantially facing the opening, and a side surface region continuously provided from the opening to the top region, a required number of through holes provided in a region covering the vicinity of the top region of the side surface region, the vicinity of the side surface region of the top region, or both the side surface region and the top region, having a predetermined diameter and communicating with the opening, A required number of covering portions that are continuously extended in a direction opposite to the top region from between the adjacent through holes and form the side surface region, and a connecting portion that can connect one circumferential end portion of one of the covering portions and a circumferential end portion of another covering portion adjacent to the one covering portion and close to the one end portion.

[0028] Here, by a substantially cylindrical protective cover having an opening, a top region facing the opening, and a side surface region continuously provided from the opening to the top region, the protective cover can be made into a substantially bag-shaped body. Thereby, since the mounting target machine body can be enclosed in the protective cover to block wind, rain, and sunlight, deterioration of the mounting target machine body due to wind, rain, sunlight, etc. can be suppressed.

[0029] Also, due to the through holes provided in the region near the top region of the side surface region, the region near the side surface region of the top region, or the region covering both the side surface region and the top region, it can have a predetermined length from the through holes to the side surface region. Therefore, the mounting target machine body can be covered using the portion from the through holes to the lower end of the side surface region.

[0030] Also, due to the through holes having a predetermined diameter, a protrusion provided on the mounting target machine body can be inserted into the through holes. Therefore, it is possible to suppress the occurrence of a gap between the surface of the mounting target machine body and the protective cover, and prevent the wind from entering and the protective cover from being peeled off from the machine body and detaching.

[0031] Also, due to the through holes communicating with the opening, a protrusion provided on the mounting target machine body can be inserted into the through holes from the opening. Therefore, the protective cover can be covered along the mounting target machine body while avoiding the protrusion. Thereby, it is possible to suppress the occurrence of a gap between the surface of the mounting target machine body and the protective cover. Therefore, not only can it prevent the wind from entering and the protective cover from being peeled off from the machine body and detaching, but also the attachment and detachment of the protective cover can be easily performed.

[0032] Further, the entire side surface of the aircraft to be attached can be covered by a required number of covering portions that are continuously extended in a direction opposite to the top region from between adjacent through holes and form a side surface region. Further, since the side surface region of the protective cover is divided into an arbitrary number, the side surface region of the protective cover can be enlarged, so that when the aircraft to be attached is enclosed by the protective cover, the work can be easily performed.

[0033] Further, the covering portions can be closed to each other by a connecting portion that can connect one end portion in the circumferential direction of one of the covering portions and one end portion in the circumferential direction of another covering portion adjacent to the covering portion and close to the one end portion, and the entire protective cover can be surely attached along the shape of the aircraft to be attached. As a result, it becomes difficult for wind to enter the protective cover, and it is possible to prevent the protective cover from detaching from the aircraft to be attached. Further, since the attachment work of the protective cover is completed only by connecting the two covering portions, the attachment work of the protective cover can be easily performed.

[0034] Further, in order to solve the above problems, a method for attaching a protective cover of the present invention includes a substantially cylindrical protective cover having an opening, a top region substantially facing the opening, and a side surface region continuously provided from the opening to the top region, and is provided in a region covering the vicinity of the top region of the side surface region, the vicinity of the side surface region of the top region, or both the side surface region and the top region, has a predetermined diameter, and is expanded to two through holes communicating with the opening, and is continuously extended in a direction opposite to the top region from between the two through holes to form a part of the side surface region. A covering step of covering the side surface of the aircraft to be attached with a first covering portion and a second covering portion that is continuously provided with the top region and forms the side surface region together with the first covering portion; After the covering step, an insertion step of inserting two protrusions provided on the aircraft to be attached into the two through holes respectively; After the insertion step, a connecting step of connecting one end portion in the circumferential direction of the first covering portion and one end portion of the second covering portion close to the one end portion, and the other end portion in the circumferential direction of the first covering portion and the other end portion of the second covering portion close to the other end portion.

[0035] Here, a substantially cylindrical protective cover having an opening, a top region substantially opposite to the opening, and a side region continuously provided from the opening to the top region can form the protective cover into a substantially bag-shaped body. Thereby, since the mounting target machine body can be enclosed within the protective cover to block wind, rain, and sunlight, deterioration of the mounting target machine body due to wind, rain, sunlight, etc. can be suppressed.

[0036] Further, a substantially cylindrical protective cover having an opening, a top region substantially opposite to the opening, and a side region continuously provided from the opening to the top region is provided in a region near the top region of the side region, near the side region of the top region, or a region covering both the side region and the top region, has a predetermined diameter, is expanded to two through holes communicating with the opening, and continuously extends in a direction opposite to the top region from between the two through holes to form a part of the side region. By a covering step of covering the side surface of the mounting target machine body with a first covering portion and a second covering portion that is continuously provided with the top region and forms the side region together with the first covering portion, the mounting target machine body can be easily enclosed and covered. That is, by simply covering the mounting target machine body with the protective cover, the mounting target machine body can be covered, so that the attachment and detachment operations of the protective cover can be easily performed.

[0037] Further, after the covering step, by an insertion step of inserting two protrusions provided on the mounting target machine body into the two through holes respectively, the mounting target machine body can be covered with the protective cover while avoiding the protrusions. Thereby, the protective cover can be closely attached to the mounting target machine body without gaps, so that not only can it prevent the mounting target machine body from deteriorating due to wind, rain, and sunlight, but also it becomes difficult for a gap to occur between the two covering portions and the mounting target machine body, and it can suppress the protective cover from detaching from the mounting target machine body due to the entry of wind.

[0038] After the insertion step, by a connecting step of connecting one circumferential end of the first covering portion and one end of the second covering portion adjacent to the one end, the other circumferential end of the first covering portion and the other end of the second covering portion adjacent to the other end, the attachment work of the protective cover can be completed only by connecting the end of the first covering portion and the end of the second covering portion. Therefore, the attachment / detachment work can be easily performed, and the protective cover can be prevented from detaching from the attachment target body.

Advantages of the Invention

[0039] The protective cover and its attachment method according to the present invention prevent the driver's seat and its peripheral devices from getting wet, soiled, and deteriorated by sunlight, and are a protective cover and its attachment method that are easy to attach and detach and difficult to detach from the attachment target body.

Modes for Carrying Out the Invention

[0041] Hereinafter, the protective cover A of the present invention will be described with reference to FIGS. 1 to 5 to facilitate understanding of the present invention. In addition, the "front (side)", "rear (side)", "right (side)", "left (side)", "upper (side)", and "lower (side)" described in this specification refer to the front-rear direction, left-right direction, and up-down direction in the state of sitting in the driver's seat.

[0042] [First Embodiment] As shown in FIGS. 1 and 2, the protective cover A has a substantially bag-like shape with the upper part closed and the lower part open, and is formed in a size capable of covering the operator part M2 described later.

[0043] The protective cover A is formed of a single fabric body A0, and has an opening A1, a top region A2 facing the opening A1, and a side region A3 continuously provided from the opening A1 to the top region A2. The fabric body A0 uses a material of No. 6 ester canvas suitable for long-term use. As other materials, it is also conceivable to use tarpaulin or Ultramax (registered trademark), but considering cost, mass, workability, durability, etc., No. 6 ester canvas is desirable.

[0044] Also, as shown in FIG. 3, the body M of a heavy machine (excavator car), which is an example of the body to which the protective cover A is attached, has a cab chamber M1 provided on a revolving body M0, and in the cab chamber M1, there are a driver's seat M20 and operating equipment M21 (hereinafter referred to as the "operator part M2") arranged around it. The body M is a so-called canopy-type body, and includes an eaves part M22 located above the driver's seat M20 and two right struts M3a and left struts M3b for instructing the eaves part M22.

[0045] The protective cover A has a shape that is slightly tapered from the top region A2 to the opening A1, and is formed to be able to enclose and cover the operator part M2 (height of about 100 cm, width of about 125 cm, depth of about 185 cm). The protective cover A also encloses a maintenance box M4 described later and is attached to the body M.

[0046] In addition, since the protective cover A has a shape that gradually narrows downward, the lower end portion of the protective cover A is attached along the shape of the machine body M and is in a state of being almost in close contact with the machine body M. Therefore, it is possible to prevent wind from entering between the protective cover A and the machine body M and to prevent the protective cover A from being peeled off and detaching from the machine body M.

[0047] Further, in the side region A3 of the protective cover A, a right slit portion A4a and a left slit portion A4b that are cut approximately upward for a length of about 62 cm from the opening A1 to the side region A3 are provided at intervals of about 67 cm. The right slit portion A4a is an example of the first slit portion, and the left slit portion A4b is an example of the second slit portion.

[0048] By these two slit portions A4a and A4b, the side region A3 of the protective cover A is divided into a rear covering portion 1 that can cover the vicinity of the rear surface portion M2d of the cab chamber M1, and a front covering portion 2 that can cover the front surface portion M2a, the right side surface portion M2b, and the left side surface portion M2c of the cab chamber M1.

[0049] In addition, an upper covering portion 3 that covers the upper part of the operator portion M2 is provided in the top region A2 of the protective cover A, and the rear covering portion 1 and the front covering portion 2 are each formed continuously with the upper covering portion 3. The rear covering portion 1 is an example of the first covering portion, and the front covering portion 2 is an example of the second covering portion.

[0050] In addition, a right end edge 11 is provided at the right side end of the rear covering portion 1 of the protective cover A, a left end edge 12 is provided at the left side end, and a lower end edge 10 is provided from the lower end of the right end edge 11 to the lower end of the left end edge 12. In the front covering portion 2, a right rear end edge 21 is provided at the right rear end, a left rear end edge 22 is provided at the left rear end, and a lower end edge 20 is provided from the lower end of the right rear end edge 21 to the lower end of the left rear end edge 22.

[0051] In addition, the right slit portion A4a is composed of the right rear end edge 21 of the front covering portion 2 and the right end edge 11 of the rear covering portion 1, and the left slit portion A4b is composed of the left rear end edge 22 of the front covering portion 2 and the left end edge 12 of the rear covering portion 1.

[0052] Also, at a position on the back side of the right slit portion A4a where the right rear edge 21 of the front covering portion 2 and the right edge 11 of the rear covering portion 1 intersect, when the protective cover A is attached to the airframe M, a right through-hole portion 23 that can abut against the periphery of the right support column M3a and is opened in a substantially circular shape is provided. Further, at a position on the back side of the left slit portion A4b where the left rear edge 22 of the front covering portion 2 and the left edge 12 of the rear covering portion 1 intersect, a left through-hole portion 24 that can abut against the periphery of the left support column M3b and is opened in a substantially circular shape is provided. In addition, the right through-hole portion 23 and the left through-hole portion 24 are each provided with edge portions 23a and 24a for reinforcement.

[0053] Also, since the protective cover A is three-dimensionally formed of a single continuous fabric body so as to be able to cover the upper surface and the peripheral surface of the operator portion M2, the entire operator portion M2 can be covered only by covering the operator portion M2 with the protective cover A.

[0054] Note that the number of slit portions provided in the side surface region A3 of the protective cover A is not necessarily limited to two, and it is also conceivable to provide a required number. For example, in the case of a canopy-type airframe provided with three support columns, it is also conceivable to provide a slit portion from the opening portion A1 to the position corresponding to the third support column.

[0055] Also, in the present embodiment, the protective cover A is provided with the rear covering portion 1, the upper covering portion 3, the front covering portion 2, and the upper covering portion 3 continuously, but it is not limited thereto. For example, it is also conceivable to prepare each covering portion as an individual fabric body and connect them by known attachment means such as hook-and-loop fasteners, snap buttons, or sewing. However, since it is also conceivable that rainwater may enter from the joint and the operator portion gets wet, or wind may enter from the joint and the protective cover may come off the airframe, it is desirable to form it as a single fabric body.

[0056] Also, as shown in FIG. 4, for the protective cover A, the lower end edge 20 of the front covering portion 2 is formed in a downwardly inclined shape. That is, when the operator portion M2 is covered with the protective cover A, the lower end edge 20 of the front side region 2F of the front covering portion 2 covers the operator portion M2 deeper than the right rear end edge 21 of the front covering portion 2. Thereby, it is possible to reliably prevent the feet of the driver's seat M20 from getting wet or dirty. Further, by attaching the protective cover A to the operator portion M2 in a downwardly inclined state, a certain tension is applied to the lower end portion of the protective cover A, whereby the vicinity of the opening A1 of the protective cover A is tightened and the protective cover A is less likely to be easily detached from the machine body M, so that the protective cover A can be reliably attached to the machine body M.

[0057] Note that the lower end portion of the protective cover is not limited to being in a downwardly inclined shape, and it may be set substantially horizontally according to the shape of the machine body M, or may be inclined in an arbitrary direction of the machine body M. Further, in this embodiment, only the lower end portion on the right side of the protective cover A is inclined, and the lower end portion on the left side is formed substantially horizontally as shown in FIG. 5, but it is also conceivable to incline both the left and right lower end portions. In this case, a stronger tension is applied to the lower end portion of the protective cover A, and further, the protective cover A can be prevented from detaching from the machine body M.

[0058] Also, in the side region A3 composed of the rear covering portion 1 and the front covering portion 2, a plurality of dart portions 4 are formed in the vertical direction. The dart portion refers to a "crease" formed by folding and sewing the fabric body A0 inside the protective cover A to a predetermined width. By providing the dart portion, a margin can be provided for the fabric body A0 in the side region A3, so that a three-dimensional shape with a bulge can be obtained. Further, by appropriately adjusting the width, length, and direction of the folded fabric body A0, the protective cover A can be made to fit various shaped machine bodies.

[0059] In this embodiment, ten dart portions are provided in the side region A3. Among these dart portions, there are main dart portions provided to maintain the side region A3 of the protective cover A in a substantially circular shape in plan view, and sub-dart portions provided to conform the shape of the side region A3 to the shape of the model of the heavy machine.

[0060] In this embodiment, the main dart portions include a right main dart portion 40 provided near the right front obliquely of the front covering portion 2, a left main dart portion 41 provided near the left front obliquely of the front covering portion 2, and a rear main dart portion 42 provided on the rear covering portion 1.

[0061] The right main dart portion 40 is provided with a length of about 72 cm in a substantially vertical direction, the left main dart portion 41 is provided with a length of about 61 cm in a substantially vertical direction, and the rear main dart portion 42 is provided with a length of about 40 cm in a substantially vertical direction. With these main dart portions 40, 41, and 42, the opening A1 can be formed in a substantially circular shape. As a result, the opening A1 can be attached along the circumferential surface of the turntable M0 or the operator portion M2 that is substantially circular in plan view (that is, the surface composed of the front surface portion M2a, the right side surface portion M2b, the left side surface portion M2c, and the rear surface portion M2d). Therefore, it is possible to prevent the wind from blowing in due to the gap generated between the opening A1 and the circumferential surface of the turntable M0 or the operator portion M2, and to prevent the protective cover A from detaching from the machine body M.

[0062] In addition, with these dart portions 40, 41, and 42, the protective cover A is formed into a substantially bag-shaped three-dimensional shape with a bulge, so that the operator portion M2 can be enclosed with a margin, and the attachment and detachment operations can be easily performed.

[0063] Also, in the peripheral region A3 of the protective cover A, four sub-dart portions 43, 44, 45, and 46 provided in the right side region 2R of the front covering portion 2 that is behind the right main dart portion 40 and covers the right side surface portion M2b of the machine body M2, two sub-dart portions 47 and 48 provided around the left through-hole portion 24, and a sub-dart portion 49 provided in the left side region 2L of the front covering portion 2 that is behind the left main dart portion 41 and covers the left side surface portion M2c of the machine body M2 are provided.

[0064] Further, the sub-darts 43, 44, 45, 46 are provided in a substantially vertical direction at predetermined intervals from the front to the rear within the right region 2R of the front covering portion 2. The length of the sub-dart 43 closest to the front is 51 cm, the length of the sub-dart 44 is 41 cm, the length of the sub-dart 45 is 43 cm, and the length of the sub-dart 46 closest to the rear is 12 cm. As a result, the right region 2R of the front covering portion 2 can have a bulge and the fabric can have slack, so that it is possible to cover including the maintenance box M4 provided so as to project to the right side of the operator portion M2.

[0065] Also, the sub-darts 47, 48 are provided substantially radially from the center of the left through-hole portion 24 having a substantially circular shape. The length of the sub-dart 47 is about 2 cm, and the length of the sub-dart 48 is about 16 cm. As a result, slack can be created in the fabric around the left through-hole portion 24, so that it is possible to easily form a bulged shape.

[0066] Also, the sub-dart 49 is provided in a substantially vertical direction near the approximate center in the front-rear direction of the left region 2L of the front covering portion 2, and its length is about 72 cm. As a result, slack is created in the left region 2L to form a bulged shape, so that it is possible to cover with the protective cover A including the handrail M5 and the safety lever M6 (a lever for hydraulic control of the machine body, and after the work is completed, the safety lever M6 is pulled upward) provided on the left side of the operator portion M2.

[0067] In this way, by providing the main darts 40 to 42, the lower end portion 10 of the rear covering portion 1 and the lower end portion 20 of the front covering portion 2 can be arranged along the periphery of the machine body M which is the attachment target of the protective cover A. Further, by providing the sub-darts 43 to 49, the shape of the side region A3 of the protective cover A can be made to conform to different shapes for each model of the machine body M.

[0068] Note that the number, length, width into which the fabric is folded, or the position where each dart part is provided of each main dart part and sub-dart part is not limited to this embodiment, and can be appropriately changed according to the shape of the aircraft to which it is attached.

[0069] Also, regarding the direction in which each dart part is provided, it is not limited to the substantially vertical direction, and it is also conceivable to provide it in the substantially horizontal direction or a direction intersecting the horizontal direction (diagonal direction). However, if the dart part is provided in the horizontal direction or the diagonal direction, it is also conceivable that rainwater will flow in from the stitching seam of the dart part and the operator part M2 will get wet. Therefore, it is desirable that each dart part be provided in the substantially vertical direction.

[0070] Note that the positions where the main dart part and the sub-dart part are provided are not limited to the above embodiment, and it is also conceivable to provide them in the front side region 2F of the front covering part 2 and the upper covering part 3 that can cover the front surface part M2a of the aircraft M2.

[0071] Also, since the folding part 5 is provided near the left rear end edge 22 of the front covering part 2, a fold line is formed from the folding part 5 to the vicinity of the left through hole part 24, so that it becomes easier to wind the fabric body M0 near the left rear end edge 22 around the left support column M3b.

[0072] Also, as shown in FIG. 5, a peak part 27 is formed such that the fabric body M0 near the left rear end edge 22 of the front covering part 2 is folded along the left support column M3b. By this peak part 27, the top region A2 is lifted, and a slope 28 is formed from the peak part 27 to the right side region 2R, the left side region 2L, and the front side region 2F, so that rainwater is less likely to accumulate in the top region A2 of the protective cover A. As a result, it is possible to suppress the protective cover A from being dented by the weight of rainwater and the operator part M2 from being exposed and being exposed to wind, rain, and sunlight.

[0073] Also, the tip of the safety lever M6 in the pulled-up state after the work is pulled up to a position substantially equivalent to the height of the backrest of the driver's seat M20. Since the slope 28 is pulled up by the peak portion 27 and the space inside the protective cover A is widened, the operator part M2 can be covered even when the safety lever M6 is in the pulled-up state.

[0074] In addition, at the entire peripheral edge A5 of the protective cover A (that is, the lower end edge 10, the right end edge 11, the left end edge 12 of the rear covering portion 1, and the lower end edge 20, the right rear end edge 21, the left rear end edge 22, and the edge portions 23a, 24a of the front covering portion 2), a folded-back portion A6 formed by doubling the edge of the fabric body A0 is provided, and a string-like body (not shown) having a predetermined thickness is inserted therein. As a result, the entire protective cover A is reinforced, so that it is possible to suppress the protective cover A from being torn by the tensile force applied to the protective cover A from various directions when the protective cover A is stretched and attached to the machine body M. The material of the string-like body is not particularly limited, but a polyester one is preferably used because it is strong against acids, alkalis, seawater, etc., has excellent weather resistance, is very strong against friction, and has excellent strength.

[0075] In addition, a right magnet body 13 for attachment is provided near the right through-hole portion 23 of the rear covering portion 1, and a left magnet body 14 for attachment is provided near the left through-hole portion 24. Further, three right magnet bodies 21a, 21b, 21c for connection are provided at predetermined intervals on the right rear end edge 21 of the front cover portion 2, and left magnet bodies 22a, 22b, 22c for connection are provided at predetermined intervals on the left rear end edge 22 of the front cover portion 2. The right magnet bodies 21a, 21b, 21c for connection and the left magnet bodies 22a, 22b, 22c for connection are examples of the connection portion.

[0076] Accordingly, first, the rear covering portion 1 covers the rear portion M1d of the cab chamber M1 by using the right magnet body 13 for attachment and the left magnet body 14 for attachment. Next, the front covering portion 2 is overlapped on the rear covering portion 1 so as to cover the right edge 11 of the rear covering portion 1 by using the right connecting magnet bodies 21a, 21b, 21c, and the front covering portion 2 is overlapped on the rear covering portion 1 so as to cover the left edge 12 of the rear covering portion 1 by using the left connecting magnet bodies 22a, 22b, 22c. Thereby, the rear covering portion 1 and the front covering portion 2 of the protection cover A can be connected by the rear portion M2d of the operator portion М2.

[0077] Regarding the above magnet bodies, it is also conceivable to substitute them with hook-and-loop fasteners, snap buttons, side release buckles, etc. However, considering the ease of attachment and detachment, magnet bodies are preferable.

[0078] Further, the protection cover A is first folded with the left region 2L of the front covering portion 2 toward the center, and then the right region 2R is folded toward the center. Then, the front region 2F is folded toward the driver's seat M20 to be substantially equal to the width of the seat surface, and finally, it is folded by overlapping the rear covering portion 1, and it can be compactly stored by placing it on the seat surface (not shown) of the driver's seat M20. Note that it is only necessary that the protection cover A can be folded compactly, and it is not limited to the above folding method.

[0079] [Second Embodiment] The protection cover B according to the second embodiment will be described below with reference to FIGS. 2 and 6. Among the configurations of the second embodiment, the structures equivalent to those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted here.

[0080] Right eyelets 25a, 25b, 25c are provided at a predetermined interval on the right rear edge 21 of the front covering portion 2 of the protection cover B, and left eyelets 26a, 26b, 26c are provided at a predetermined interval on the left rear edge 22.

[0081] Here, the tightening rope R is alternately passed through to connect the right pawl 25a and the left pawl 26a, the right pawl 25b and the left pawl 26b, and the right pawl 25c and the left pawl 26c. As a result, the right rear edge 21 and the left rear edge 22 of the front covering portion 2 can be stretched and attached, so that the protective cover A can be more securely attached to the aircraft M even in strong winds, and the protective cover A can be prevented from detaching from the aircraft M.

[0082] [Mounting method of protective cover A and protective cover B] First, with reference to FIG. 7, the mounting method of the protective cover A will be described, and then the mounting method of the protective cover B will be described.

[0083] [Coating process (ST01)] First, the operator part M2 of the aircraft M is covered by enclosing it from the opening A1 of the protective cover A. Since the protective cover A is formed in a size that can enclose the operator part M2, by simply covering the operator part M2 with the protective cover A, the front surface part M2a, the right side surface part M2b, and the left side surface part M2c of the operator part M2 can be covered by the front covering portion 2.

[0084] [Insertion process (ST02)] Also, the right support M3a and the left support M3b are respectively inserted into the right slit part A4a and the left slit part A4b of the protective cover B, and the rear covering part 1 is pulled out from between the right support M3a and the left support M3b. As a result, while avoiding the right support M3a and the left support M3b, the periphery of the right support M3a and the left support M3b can be covered by the rear covering part 1 and the front covering part 2, and the rear surface part M2d of the operator part M2 can be covered by the rear covering part 1. That is, both covering parts are pressed by the right support M3a and the left support M3b, and irregular wrinkles are generated in both covering parts around the right support M3a and the left support M3b, and gaps are not generated between both covering parts and the aircraft M, so that both covering parts can be closely attached to the aircraft M. Thereby, it is possible to prevent the wind from entering between both covering parts and the aircraft M and peeling off and detaching the protective cover A from the aircraft M.

[0085] [Mounting process (ST03)] Also, after covering the operator part M2 with the protective cover A, attach the right magnet body 13 for pasting of the rear covering part 1 near the lower side of the right support M3a of the rear surface part M2d of the operator part M2. Next, attach the left magnet body 14 for pasting near the lower side of the left support M3b of the rear surface part M2d of the operator part M2. As a result, since the right magnet body 13 for pasting and the left magnet body 14 for pasting are magnetically attached to the rear surface part M2d, the rear covering part 1 is attached to the rear surface part M2d of the operator part M2, so that the rear covering part 1 becomes difficult to easily detach from the rear surface part M2d.

[0086] 〔Connection process (ST04)〕 Next, from above the rear covering part 1 so as to cover the right end edge 11 of the rear covering part 1, attach the right connecting magnets 21a, 21b, 21c provided near the right rear end edge 21 of the front covering part 2 to the rear surface part M2d. Also, from above the rear covering part 1 so as to cover the left end edge 12 of the rear covering part 1, attach the left connecting magnets 22a, 22b, 22c provided near the left rear end edge 22 of the front covering part 2 to the rear surface part M2d. As a result, the front covering part 2 can be attached to the rear surface part M2d with the rear covering part 1 interposed therebetween to connect the front covering part 2 and the rear covering part 1, so that the rear covering part 1 and the front covering part 2 become difficult to easily detach from the rear surface part M2d.

[0087] Here, it is also conceivable to omit the attachment process (ST03). Even if the rear covering part 1 is not attached to the machine body M, in the connection process (ST04), since the front covering part 2 is attached to the rear surface part M2d with the rear covering part 1 interposed therebetween, the rear covering part 1 is surely attached to the machine body M. In addition, when it is necessary to more surely attach the rear covering part 1 to the machine body M, it is desirable to provide the attachment process (ST03).

[0088] Next, the attachment method of the protective cover B will be described. Pass the tightening ropes R through the right dovetails 25a and left dovetails 26a, right dovetails 25b and left dovetails 26b, and right dovetails 25c and left dovetails 26c provided on the protective cover B. Specifically, connect the right dovetail 25a and the left dovetail 26a by passing the tightening rope R through them, connect the right dovetail 25b and the left dovetail 26b by passing the tightening rope R through them, and connect the right dovetail 25c and the left dovetail 26c by passing the tightening rope R through them.

[0089] As a result, the right rear edge 21 and the left rear edge 22 at both circumferential ends of the front covering portion 2 can be pulled and fixed, so that the protective cover B can be more securely attached to the airframe M, and it is possible to prevent the protective cover B from being peeled off from the airframe M by the wind and detaching.

[0090] In this way, the protective cover and the method of attaching the protective cover to which the present invention is applied can prevent the driver's seat and its peripheral devices from getting wet, dirty, and deteriorating due to sunlight, and can provide a protective cover and a method of attaching the same that are easy to attach and detach and difficult to detach from the airframe to be attached.
