Description

The present invention relates to a protective cover for heavy machinery, such as a mini excavator, that protects the area around the driver's seat by covering it.

Conventionally, known protective means for heavy machinery that provide protection by covering the area around the driver's seat include the protective means for construction machinery described in Patent Document 1 and the protective means for work machinery described in Patent Document 2.

The protective means used in the construction machine of Patent Document 1 is intended to protect the windows provided in the cab. Specifically, a head guard is provided on the top surface of the cab, and a front protective cover, a rear protective cover, a left protective cover, and a right protective cover are housed in a space within the head guard so that they can be inserted and removed. When the cab is not in use, the front protective cover, rear protective cover, left protective cover, and right protective cover are removed from within the head guard, and the upper and lower front windows of the cab are covered with the front protective cover, the rear window is covered with the rear protective cover, the front left window and rear left window are covered with the left protective cover, and the front right window and rear right window are covered with the right protective cover, thereby protecting them from thrown stones, etc.

The protective means used in the work machine of Patent Document 2 aims to provide a work machine equipped with a canopy of a simple structure that effectively prevents palm leaves or the like from hitting the operator during work. Specifically, the work machine has a driver's seat and a canopy on an upper rotating body. The canopy has a roof that covers the driver's seat, multiple pillars that support the roof, and a leaf guard that covers the periphery of the driver's seat. The leaf guard has a swingable door section, and a stopper that regulates the swinging of the door section is provided on the door section. The stopper has an outer clamping section, an inner clamping section, and an opening/closing lever. By operating the opening/closing lever, the inner clamping section is displaced between a closed position where it can contact the pillar and an open position where it cannot contact the pillar, and in the closed position, the pillar is sandwiched between the outer clamping section and the inner clamping section.

However, the conventional protective measures used in the above-mentioned construction machines and the like have the following problems:

As a protective measure, multiple panel components are used in combination, or multiple net panel components are used in combination, which leads to significant increases in cost, increases in overall size and weight, and is difficult to store, making it difficult to secure storage space. Moreover, installation and removal are tedious and time-consuming, making it difficult to carry out work efficiently, and so these have basic negative aspects.

In particular, because they are attached to construction machinery (heavy machinery) with a cabin made of a body frame or body panel that covers all or part of the driver's seat, they are configured as a dedicated protective measure for each piece of heavy machinery, and cannot be used on heavy machinery that does not have a cabin, i.e., heavy machinery where the area around the driver's seat is exposed, and therefore lack flexibility and versatility.

In the past, there was no adequate means of protection for heavy machinery that did not have a cabin, and when the heavy machinery was parked and stored outdoors, rain, snow, sunlight (ultraviolet rays), etc. caused the PVC driver's seat and the area around the driver's seat, such as the operating parts made of plastic material located in front of the driver's seat, to deteriorate over time, resulting in a decrease in weather resistance and durability, making maintenance more difficult and causing the driver's seat to tear, discolor, and other deterioration in appearance, as well as being prone to malfunctions.

The present invention aims to provide a protective cover for heavy machinery that solves the problems that exist in the background technology.

In order to solve the above-mentioned problems, the present invention provides a heavy machine protective cover 1 that provides protection by covering the area around the driver's seat in heavy machine M, and is characterized by comprising a cover base 3 in which a surrounding cover member 3s that covers at least the area around the driver's seat, including the driver's seat Md provided on the heavy machine M and the operating unit Mc provided in front of the driver's seat Md, and an upper cover member 3u located at the upper end of the surrounding cover member 3s are integrally formed from a waterproof flexible sheet member R, a cover body 2 in which a plurality of lower hole portions 4... having a predetermined inner diameter are provided at predetermined intervals along the lower end edge portion 3sd of the surrounding cover member 3s near the lower end edge portion 3sd of the surrounding cover member 3s, and an upper hole portion 5 having a predetermined inner diameter is provided at a predetermined position on the upper surface 3uf of the upper cover member 3u, and a fixing rope 7 having an upper rope member 7u that can be inserted into the upper hole portions 5 and a lower rope member 7d that can be inserted into the lower hole portions 4...

In this case, according to a preferred embodiment of the invention, the sheet member R can be made of tarpaulin fabric. The surrounding cover member 3s can be formed so that the height Hr of one side Fr in the axis-perpendicular direction Fh is higher than the height Hf of the other side Ff. The one side Fr of the surrounding cover member 3s can be a flat back portion 3srm located on the backrest Mdr of the driver's seat Md, and the color of the outer surface As of this back portion 3srm can be selected to be different from the color of at least the outer surface Ae other than the back portion 3srm. On the other hand, a rubber rope can be used for the fixing rope 7. On the other hand, the cover body 2 may be composed of a cylindrically formed peripheral cover member 3s and an upper cover member 3u that closes the upper end of the peripheral cover member 3s, or may be composed of a single sheet cover 3o, and some of the end edges 3oa and 3ob, 3oc and 3od, 3oe and 3of, and 3og and 3oh may be detachable from each other in an assembly type. In this case, the sheet cover 3o may be configured so that the sheet cover 3o can be rolled up by attaching rod members 8f, 8r to the front end edge portion 3ox and/or the rear end edge portion 3oy, and at least one of the rod members 8f (8r) may be used as a winding core.

The heavy machinery protective cover 1 according to the present invention, which has such a configuration, provides the following remarkable effects:

(1) The cover body 2 is provided with a cover base 3 in which a surrounding cover member 3s that covers at least the area around the driver's seat Md provided on the heavy machine M, including the operating unit Mc provided in front of the driver's seat Md, and an upper cover member 3u located at the upper end of the surrounding cover member 3s are integrally formed from a waterproof flexible sheet member R, so that by folding it, the entire product can be made small, compact, and lightweight, and can be manufactured at low cost. Moreover, it has the basic effect of being easy to store and can be easily and quickly attached and removed.

(2) In particular, it has excellent flexibility and versatility, as it can be used even with heavy machinery M that does not have a cabin, and even when the heavy machinery M is parked and stored outdoors, it can effectively protect the driver's seat Md and the area around the driver's seat, including the operating unit Mc located in front of the driver's seat Md, from rain, snow, sunlight (ultraviolet rays), etc., thereby suppressing deterioration over time and improving weather resistance and durability. This not only makes maintenance easier and reduces costs, but also prevents or significantly reduces deterioration of the appearance of the driver's seat, such as tears and discoloration, and even breakdowns.

(3) In a preferred embodiment, tarpaulin fabric is used as the material for the sheet member R. Due to the characteristics of the fabric, such as flame resistance, waterproofness, and weather resistance, it can be selected as the most suitable material from the viewpoint of providing protection from rain, snow, sunlight (ultraviolet rays), etc.

(4) In a preferred embodiment, the height Hr of the surrounding cover member 3s on one side Fr in the axis-perpendicular direction Fh is made higher than the height Hf of the other side Ff. This allows the relatively high backrest portion Mdr to be matched with the operating portion Mc, which is located relatively low and forward of the backrest portion Mdr, in terms of surrounding the outer periphery, thereby improving the fit when worn.

(5) In a preferred embodiment, by selecting one side Fr of the surrounding cover member 3s as the flat back portion 3srm located at the backrest portion Mdr of the driver's seat Md, this back portion 3srm can be positioned at the backrest portion Mdr, so that the protective cover 1 can be easily and reliably aligned with respect to the area around the driver's seat.

(6) In a preferred embodiment, the color of the outer surface As on the rear portion 3srm can be selected to be different from the color of the outer surface Ae other than the rear portion 3srm, making it possible to visually and intuitively identify the mark. This not only improves functionality from the standpoint of facilitating installation work, but also enhances the overall design of the heavy machine M.

(7) In a preferred embodiment, if a rubber rope is used for the fixing rope 7, the lower end edge 3sd of the surrounding cover member 3s can be pressed (fitted) against the driver's seat, making it possible to attach it more reliably and stably even against wind and rain, etc., and effectively avoiding problems such as being blown away by the wind or rain, etc. entering the cover. In addition, the upper cover member 3u can be reliably and stably tilted with the upper hole portion 5 of the upper cover member 3u as a fulcrum, allowing rain, etc. to fall off quickly.

(8) In a preferred embodiment, when constructing the cover body 2, if it is constructed from a cylindrically formed peripheral cover member 3s and an upper cover member 3u that closes the upper end of this peripheral cover member 3s, it can be easily fitted to the driver's seat Md of the actual heavy equipment M and the area around the driver's seat, including the operating unit Mc provided in front of the driver's seat Md, so that the entire area can be covered more reliably.

(9) In a preferred embodiment, the cover body 2 is formed from a single flat seat cover 3o, and some of the edge portions 3oa and 3ob, 3oc and 3od, 3oe and 3of, and 3og and 3oh are detachable from each other in an assembly-type configuration. When not in use, the cover body 2 can be unfolded into a single seat cover 3o, which can be easily folded, improving storability and storage.

(10) In a preferred embodiment, rod members 8f, 8r are attached to the front edge portion 3ox and/or the rear edge portion 3oy of the seat cover 3o, and the seat cover 3o is configured to be rolled up around at least one of the rod members 8f (8r) as a winding core. This allows the seat cover 3o to be wound into a roll around the rod member 8f (8r) as a winding core, ensuring easy storage and storability.

Next, we will present a preferred embodiment of the present invention and explain it in detail with reference to the drawings.

First, to facilitate understanding of the protective cover 1 according to this embodiment, an overview of the heavy machinery M for which this protective cover 1 is to be used will be described with reference to Figures 1 and 11.

As shown in FIG. 1, a mini-excavator is shown as an example of heavy machinery M. This mini-excavator (M) has a pair of travelling crawlers 51p, 51q on the left and right sides of a chassis 50, and a rotating body 52 on the upper end of the chassis 50. In addition, a cab 53 is provided on top of the rotating body 52, and a shovel mechanism 54 consisting of a boom 55, an arm 56, a bucket 57, etc. is provided on the front end of the cab 53.

As shown in FIG. 11, the rear of the cab 53 is provided with a driver's seat Md having a backrest Mdr, and in front of the cab Md is an operation section Mc including various operation levers 58a, 58b, 58c..., various operation switches 59..., a display panel 60, etc. In addition, the rear end of the cab 53 is provided with a roof (canopy) 62 supported on the upper ends of pillars 61 that stand upright, and handrails Mh... made of pipe frames are installed in the front, left side, and right side of the cab 53. Therefore, the area around the driver's seat includes the driver's seat Md and the operation section Mc located in front of the driver's seat Md.

Next, the heavy machinery protective cover 1 according to this embodiment, which is suitable for use with such heavy machinery M (mini excavator), will be described with reference to the drawings.

First embodiment

First, the configuration of the heavy equipment protective cover 1 according to the first embodiment will be described with reference to Figures 2 to 7.

The protective cover 1 has the function of protecting the area around the driver's seat of the heavy equipment M, and is broadly composed of a cover body 2 and a fixing rope 7.

As shown in Figures 2-6, the cover body 2 comprises a cylindrical surrounding cover member 3s and an upper cover member 3u that closes the upper end opening of the surrounding cover member 3s. The surrounding cover member 3s and the upper cover member 3u are each formed from a waterproof flexible sheet member R. As a result, the cover base 3 is formed by integrating the surrounding cover member 3s and the upper cover member 3u by sewing or the like. In this case, it is preferable to use tarpaulin fabric as the material for the sheet member R. If tarpaulin fabric is used as the material, it can be selected as the optimal material from the viewpoint of protection from rain, snow, sunlight (ultraviolet rays), etc., due to the characteristics of the fabric, such as flame resistance, waterproofness, and weather resistance.

The surrounding cover member 3s has a cylindrical shape with a deformed hexagonal cross section in plan view. More specifically, the rear surface 3sr is formed of a central rear surface portion 3srm and inclined surface portions 3srp and 3srq located on both sides of the rear surface portion 3srm, as shown in FIG. 4, with the inclination angle of each inclined surface portion 3sp and 3sq relative to the rear surface portion 3srm being 45° in the illustrated example.

As a result, the back surface 3srm is located on one side (rear side) Fr of the surrounding cover member 3s, and the flat back surface 3srm is located on the backrest Mdr of the driver's seat Md. In this way, by selecting the flat back surface 3srm located on the backrest Mdr of the driver's seat Md as one side (rear side) Fr of the surrounding cover member 3s, this back surface 3srm can be positioned on the backrest Mdr, so that the protective cover 1 can be easily and reliably aligned with respect to the area around the driver's seat.

Furthermore, as shown in FIG. 6, the color of the outer surface As at the rear portion 3srm is selected to be different from the color of the outer surface Ae other than the rear portion 3srm. In the illustrated example, the color of the outer surface As is selected to be blue, and the color of the outer surface Ae other than the rear portion 3srm is selected to be gray. In this way, if the color of the outer surface As at the rear portion 3srm is selected to be different from the color of the outer surface Ae other than the rear portion 3srm, it can be identified as a visual and intuitive marker, which not only improves functionality from the perspective of facilitating installation work, but also improves the overall design, including the heavy equipment M.

As shown in Fig. 3, the surrounding cover member 3s is formed so that the height Hr of one side (rear side) Fr in the axis-perpendicular direction Fh is higher than the height Hf of the other side (front side) Ff. As a result, the shape of the upper end opening edge of the surrounding cover member 3s is inclined downward toward the front as shown in Fig. 3. By forming it in this way, the relatively high backrest part Mdr can be matched to the operating part Mc, which is located relatively low and forward of the backrest part Mdr, in terms of surrounding the outer periphery, thereby improving the fit when worn.

As shown in Figure 5, the lower edge of the surrounding cover member 3s is folded back over a predetermined width to form a double-layered reinforcing surface 3sn. The lower edge of this reinforcing surface 3sn becomes the lower edge portion 3sd of the surrounding cover member 3s, so multiple pilot holes 4... with a predetermined inner diameter are provided at predetermined intervals along the lower edge portion 3sd in the reinforcing surface 3sn adjacent to this lower edge portion 3sd. The pilot holes 4... can be easily provided, for example, by attaching metal eyelets 31.

On the other hand, since the upper cover member 3u is provided to close the upper end opening of the surrounding cover member 3s, as described above, it is formed separately from the surrounding cover member 3s and integrated by sewing or the like. Furthermore, as shown in FIG. 4, an upper hole portion 5 having a predetermined inner diameter is provided at a predetermined position on the upper surface 3uf of the upper cover member 3u. In this case, for example, a triangular attachment piece 32 is formed from a sheet member R made of the same material as the upper cover member 3u, and one side of this attachment piece 32 is attached and fixed to the upper surface 3uf of the upper cover member 3u. In addition, a metal eyelet 33 similar to the lower hole portion 4 described above is attached to this attachment piece 32, so that the upper hole portion 5 can be easily provided.

On the other hand, the fixing rope 7 uses an upper rope member 7u shown in FIG. 8 that can be inserted into the upper hole portion 5 and a lower rope member 7d shown in FIG. 9 that can be inserted into the lower hole portion 4. For the upper rope member 7u and lower rope member 7d that constitute the fixing rope 7, it is desirable to use a rubber rope having a diameter that can be inserted into the lower hole portion 4 and the upper hole portion 5. If such a rubber rope is used for the fixing rope 7, the lower end edge portion 3sd of the surrounding cover member 3s can be pressed (closely attached) to the driver's seat, so that it can be attached more reliably and stably against wind and rain, etc., and problems such as being blown away by the wind or rain, etc. can be effectively avoided. In addition, the upper cover member 3u can be tilted reliably and stably with the upper hole portion 5 of the upper cover member 3u as a fulcrum, so that rain, etc. can be quickly dropped.

In this case, the fixing rope 7 may be composed of an upper rope member 7u and a lower rope member 7d, which are separate and independent, as shown in the example, or a single continuous rope may be used. That is, one side of a single rope can be used as the lower rope member 7d and the other side as the upper rope member 7u. The upper rope member 7u and the lower rope member 7d may be connected by tying the ends together, or may be connected using a fastener as shown in Figures 8 and 9. The embodiment shows a case where a rope stopper 35 is used as the fastener.

Next, the method of using (attaching) the protective cover 1 according to the first embodiment will be described with reference to Figures 1 to 11.

Now, let us assume that a heavy machine M that has finished using is parked at a designated parking area outdoors, and that the protective cover 1 according to this embodiment is to be attached to this heavy machine M.

First, the protective cover 1 according to this embodiment is prepared. The protective cover 1 is composed of a cover body 2 and a fixing rope 7, and two methods of installation can be envisioned depending on the order in which the fixing rope 7 is attached. That is, the first method is to attach the cover body 2 to the heavy equipment M, and then attach the fixing rope 7 to the attached cover body 2, and the second method is to attach the fixing rope 7 to the cover body 2 in advance, and then attach the cover body 2 with the fixing rope 7 attached to the heavy equipment M. In the embodiment, the second method is described, but the first method can also be implemented in the same way, and can be selected depending on the situation, the type of heavy equipment M, etc.

Figure 10 shows the state in which the fixing rope 7 is attached to the cover body 2, Figure 10 (a) shows the state in which one end of the upper rope member 7u is connected to the upper hole portion 5, and Figure 10 (b) shows the state in which the lower rope member 7d is attached to the lower hole portion 4...

First, one end of the upper rope member 7u is connected to the upper hole 5. In this case, as shown in FIG. 8, one end of the upper rope member 7u may be connected using a plastic rope stopper 35, or as shown in FIG. 10(a), one end of the upper rope member 7u may be directly tied to the upper hole 5. At this time, it is desirable to also attach a rope stopper 35 to the other end of the upper rope member 7u, that is, to insert the other end of the upper rope member 7u into the hole 35h of the rope stopper 35 as shown in FIG. 8.

When attaching the lower rope member 7d, as shown in FIG. 10(b), the lower rope member 7d is inserted into the adjacent lower holes 4 in sequence, that is, alternately inserted into the inner and outer sides of each lower hole 4. At this time, it is desirable to attach the holes 35h (see FIG. 8) of the rope stoppers 35 to the lower rope members 7d located at the handrails Mh of the heavy equipment M. FIG. 10(b) shows an example in which four rope stoppers 35 are attached. Furthermore, it is desirable to attach a rope stopper 35e for connection to one end of the lower rope member 7d. The rope stopper 35e has a second hole through which the other end of the lower rope member 7d is inserted.

The cover body 2 with the upper rope member 7u and lower rope member 7d attached is then attached by covering the driver's seat Md of the heavy machine M and the area around the driver's seat, including the operating unit Mc located in front of the driver's seat Md, as shown in FIG. 11. This allows the area around the driver's seat to be accommodated inside the cover body 2 through the lower end opening. At this time, as shown in FIG. 7, the circumferential attachment position of the cover body 2 relative to the area around the driver's seat is determined by the back portion 3srm, which serves as a landmark, and is aligned so that this back portion 3srm is positioned at the backrest portion Msr of the driver's seat Ms. In this way, the cover body 2 according to this embodiment can be easily attached by simply covering the area around the driver's seat from above.

Once the cover body 2 is attached, both ends of the lower rope member 7d are pulled to press the lower edge of the cover body 2 against the area around the driver's seat, and then one end of the lower rope member 7d is joined to the other end. In the example shown, the other end of the lower rope member 7d is joined to a rope stopper 35e to secure it so that it does not easily come off. Also, as shown in Figure 9, the lower rope member 7d located at the handrail part Mh is wrapped in a semicircular shape around the periphery of the handrail part Mh on the area around the driver's seat, and is fixed by the rope stopper 35 on the outside of the handrail part Mh. As a result, the lower side of the protective cover 1 is fixed to the heavy equipment M. This state is shown in Figure 1.

Then, the other end of the upper rope member 7u is connected to the upper end frame 61s at the upper end of the support 61 that supports the roof 62 described above. In this case, as shown in FIG. 8, the other end of the upper rope member 7u can be hooked onto the upper end frame 61s and fixed with the rope stopper 35. Note that while the example shows an example of fixing with the rope stopper 35, various fixing means can be used, such as fixing to the roof (canopy) 62 or the upper end frame 61s using a magnet. This state is shown in FIG. 1 and FIG. 7.

When constructing the cover body 2, the protective cover 1 of the first embodiment is constructed from a cylindrically formed peripheral cover member 3s and an upper cover member 3u that closes the upper end of this peripheral cover member 3s. This has the advantage that it can be easily fitted to the driver's seat Md of the actual heavy machinery M and the area around the driver's seat, including the operating unit Mc located in front of the driver's seat Md, and therefore can more reliably cover the entire area.

Second embodiment

Next, the configuration of the heavy equipment protective cover 1 according to the second embodiment will be described with reference to Figures 12 to 15.

As shown in FIG. 13, the heavy equipment protective cover 1 according to the second embodiment is formed from a single flat sheet cover 3o when constructing the cover body 2. Note that the direction of the arrow Fr in FIG. 13 indicates the rear.

As shown in the figure, the seat cover 3o is an integral unit of a rectangular upper sheet portion 11, left and right sheet portions 12 and 13 that are square and resemble right-angled triangles, a rectangular front sheet portion 14, and a rectangular rear sheet portion 15, and can be changed into three modes Dc, Du, and Dr. That is, it can be changed into three forms: the deployment mode Dc shown in FIG. 13 in which it is deployed flat, the usage mode shown in FIG. 12 in which it is assembled into a three-dimensional shape, and the storage mode Dr shown in FIG. 14 in which it is wound up in a roll.

For this reason, some of the end edges of the seat cover 3o, i.e., the right end edge 3oa of the front sheet portion 14 and the front end edge 3ob of the right sheet portion 13, the left end edge 3oc of the front sheet portion 14 and the front end edge 3od of the left sheet portion 12, the right end edge 3oe of the rear sheet portion 15 and the rear end edge 3of of the right sheet portion 13, and the left end edge 3og of the rear sheet portion 15 and the rear end edge 3oh of the left sheet portion 12, are configured to be detachable by hook-and-loop fasteners 16ab, 16cd, 16ef, 16gh, or other hook-and-loop fasteners.

When using the seat cover 3o, the end edges 3oa and 3ob are attached to each other, the end edges 3oc and 3od are attached to each other, the end edges 3oe and 3of are attached to each other, and the end edges 3og and 3oh are attached to each other, so that the seat cover 3o can be assembled in the usage mode Du shown in FIG. 12. In this case, the upper sheet portion 11 constitutes the upper cover member 3u according to the present invention, and the left and right sheet portions 12, 13, the front sheet portion 14, and the rear sheet portion 15 constitute the surrounding cover member 3s according to the present invention.

When not in use, the end edges 3oa and 3ob can be detached from each other, the end edges 3oc and 3od can be detached from each other, the end edges 3oe and 3of can be detached from each other, and the end edges 3og and 3oh can be detached from each other to unfold into a single flat sheet cover 3o in the unfolded mode Dc shown in FIG. 13. In this way, the heavy equipment protective cover 1 according to the second embodiment is constructed in an assembled manner, and when not in use, it can be unfolded into a single flat sheet cover 3o, which can be easily folded and improves storability and storage.

On the other hand, a pair of fixing bands 17p, 17q protruding outward in the perpendicular direction from the front end edge portion 3ox are fixed to the front seat portion 14, and a pair of fixing bands 18p, 18q protruding outward in the perpendicular direction from the rear end edge portion 3oy are fixed to the rear seat portion 15, and a pair of fixing bands 19p, 19q protruding outward in the perpendicular direction from the left and right end edges 3og, 3oe are fixed. The tip portions of the fixing bands 17p, 17q, 18p, 18q and the tip portions of the fixing bands 19p, 19q can be attached and detached to the seat cover 3o side by hook-and-loop fasteners or other hook-and-loop fasteners or other hook-and-loop fasteners, so that when in use, the fixing bands 17p, 17q, 18p, 18q and the fixing bands 19p, 19q can be wrapped around nearby handrail portions Mh, etc. to fix the seat cover 3o.

Furthermore, as shown in FIG. 13, rod members 8f, 8r are attached to the front edge portion 3ox and/or the rear edge portion 3oy (or in the vicinity of these) of the seat cover 3o, and the seat cover 3o is configured so that it can be rolled up around at least one of the rod members 8f (8r) as a winding core. The rod members 8f, 8r are preferably rod or pipe material with an outer diameter of about 1.5-2.5 cm and suitable flexibility.

When not in use, the left sheet portion 12 and the right sheet portion 13 of the seat cover 3o in the unfolded mode Dc shown in FIG. 13 can be folded so that they overlap the upper sheet portion 11, thereby making the entire seat cover 3o into a rectangular shape, and the seat cover 3o can be wound up into a roll around the rod member 8f (8r) as a winding core to be in the storage mode Dr shown in FIG. 14. In this way, the seat cover 3o in the unfolded mode Dc can be wound up into a roll around the rod member 8f (8r) as a winding core, ensuring even easier storage and storability. In FIG. 14, 21, 21 indicate storage fixing bands, but such storage fixing bands 21, 21 may be prepared separately, or may be combined with the above-mentioned fixing bands 17p, 17q or fixing bands 18p, 18q, etc.

In other configurations, the lower edge of the seat cover 3o in use mode Du is folded back over a predetermined width as shown in FIG. 12 to form a double-layered reinforcing surface 3sn, and the lower edge of this reinforcing surface 3sn becomes the lower edge portion 3sd of the surrounding cover member 3s. Therefore, in the reinforcing surface 3sn adjacent to this lower edge portion 3sd, a plurality of lower holes 4... having a predetermined inner diameter are provided at predetermined intervals along the lower edge portion 3sd. Furthermore, a triangular attachment piece 32 is fixed near the rear edge portion of the upper sheet portion 11, and upper holes 5 are provided in this attachment piece 32. This can be configured in the same way as in the first embodiment.

When using the heavy equipment protective cover 1 according to the second embodiment, as shown in FIG. 15, the upper rope member 7u and the lower rope member 7d are attached to the seat cover 3o in the use mode Du in the same manner as in the first embodiment, and the seat cover 3o is attached by covering the driver's seat Md of the heavy equipment M and the area around the driver's seat, including the operating unit Mc located in front of the driver's seat Md. After the seat cover 3o is attached, both ends of the lower rope member 7d are pulled to press the lower edge of the cover body 2 against the area around the driver's seat, and then one end side and the other end side of the lower rope member 7d are joined. Then, the fixing bands 17p, 17q, 18p, 18q and the fixing bands 19p, 19q can be wrapped around nearby handrails Mh, etc., or the seat cover 3o can be fixed using the rope stopper 35 in the first embodiment.

The second embodiment differs from the first embodiment in that the bottom end position of the seat cover 3o is set at a slightly higher position and that it can be fixed by fixing bands 17p, 17q, 18p, 18q and fixing bands 19p, 19q, but it can be basically constructed and used in the same way as the first embodiment. For this reason, in Figures 12-15 of the second embodiment, the same parts as those in Figures 1-11 of the first embodiment are given the same reference numerals to clarify the configuration, and detailed explanations of them will be omitted.

Therefore, according to the heavy machinery protective cover 1 of this embodiment, as a basic configuration, it is provided with a cover base 3 in which a surrounding cover member 3s that covers at least the area around the driver's seat Md provided on the heavy machinery M and the operating unit Mc provided in front of the driver's seat Md, and an upper cover member 3u located at the upper end of the surrounding cover member 3s are integrally formed from a waterproof flexible sheet member R, a cover body 2 in which a plurality of lower hole portions 4... having a predetermined inner diameter are provided at predetermined intervals along the lower end edge portion 3sd of the surrounding cover member 3s near the lower end edge portion 3sd of the surrounding cover member 3s, and an upper hole portion 5 having a predetermined inner diameter is provided at a predetermined position on the upper surface 3uf of the upper cover member 3u, and a fixing rope 7 having an upper rope member 7u that can be inserted into the upper hole portions 5 and a lower rope member 7d that can be inserted into the lower hole portions 4... are provided. Therefore, by folding, the entire product can be made small, compact, and lightweight, and can be manufactured at low cost. Moreover, the basic effect is that it is easy to store (store), and can be easily and quickly installed and removed. In particular, it is flexible and versatile, and can be used even with heavy machinery M that does not have a cabin. Even when the heavy machinery M is parked outdoors for storage, the driver's seat Md and the area around the driver's seat, including the operating unit Mc located in front of the driver's seat Md, can be effectively protected from rain, snow, sunlight (ultraviolet rays), etc., thereby suppressing deterioration over time and improving weather resistance and durability. This makes it possible to facilitate maintenance and reduce costs, and to avoid or significantly reduce deterioration of the appearance of the driver's seat, such as tears and discoloration, and even breakdowns.

Although the preferred embodiment has been described in detail above, the present invention is not limited to such an embodiment, and the detailed configuration, shape, material, quantity, numerical values, etc. can be changed, added, or deleted as desired without departing from the spirit of the present invention.

For example, the driver's seat Md provided on the heavy machine M and the area around the driver's seat including the operating unit Mc provided in front of the driver's seat Md are not limited to the illustrated parts, but may include handrails Mh, etc. in the embodiment. In addition, it is optimal to use tarpaulin fabric as the material for the sheet member R, but other materials may be used. Furthermore, it is desirable to form the surrounding cover member 3s so that the height Hr of one side Fr in the axis-perpendicular direction Fh is higher than the height Hf of the other side Ff, but it may be formed under other conditions depending on the type of heavy machine M, etc. On the other hand, an example is shown in which the back portion 3srm is formed in a flat shape located at the backrest portion Mdr of the driver's seat Md on one side Fr of the surrounding cover member 3s, but this is not a required requirement. In addition, in this case, the color of the outer surface As of the back portion 3srm is selected to be a different color from the color of the outer surface Ae other than the back portion 3srm, but other patterns, letters, or figures may be displayed. Furthermore, it is preferable to use a rubber rope as the fixing rope 7, but materials other than rubber, such as non-elastic materials such as artificial fibers or natural fibers, may also be used.

The heavy machinery protective cover of the present invention can be used to protect the area around the driver's seat in various heavy machinery such as mini excavators that do not have a cabin.
