Description

[Technical Field]

[0001] The present invention relates to a protective cover for a work machine. [Background technology]

[0002] Hydraulic excavators and other work machines used in construction and other work are generally often stored parked outdoors at work sites. In particular, small hydraulic excavators known as mini excavators, weighing less than 5 tons, are often designed with a canopy-type driver's seat exposed to the outside, with only a roof supported by pillars, rather than a box-shaped cab (or cabin) surrounding the driver's seat. Therefore, while stored outdoors, they may be exposed to rain, snow, and mud. Furthermore, depending on the work site environment, the driver's seat may be damaged by flying debris or falling rocks generated during crushing work, for example. Therefore, it is desirable to attach a protective cover to the driver's seat to protect it from dirt and scratches.

[0003] For example, Patent Document 1 discloses a cover for a hydraulic excavator that includes a seat member that is placed over the driver's seat to protect the seat when the hydraulic excavator is not in operation, a fixing member that fixes the seat member to the hydraulic excavator, and a holding member that holds the folded seat member behind the driver's seat when stored. The seat member is formed by joining multiple pieces of fabric together to appropriately form a desired shape according to the size of the driver's seat. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-179384 Summary of the Invention [Problem to be solved by the invention]

[0005] A protective cover for protecting the driver's section, like the hydraulic excavator cover described in Patent Document 1, is formed of a sheet member large enough to cover the entire driver's seat or the driver's seat together with the surrounding operating devices. Therefore, the width of the sheet member is at least 1 meter. This makes the task of folding the sheet member when storing the protective cover complicated, and also makes it difficult to store the sheet member compactly.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a protective cover for a work machine that can be easily and compactly assembled. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a protective cover for a work machine, which is used on a work machine, and which comprises a sheet body formed from a flexible sheet material, and the sheet body is provided with at least one ridge extending from one end to the other end in the width direction and protruding from at least a portion of one of the front and back surfaces of the sheet material, and a pair of magnets are attached to both sides of the ridge, with the magnetic poles of the pair of magnets on the same side of the sheet body being opposite polarities and attracting each other when the sheet body is folded along the ridge. [Effects of the Invention]

[0008] The protective cover for a work machine according to the present invention can be put together simply and compactly. Problems, configurations and effects other than those described above will become apparent from the following description of the embodiment. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] The protective cover according to the embodiment of the present invention is a protective cover for a work machine that is particularly suitable for use with a work machine such as a small hydraulic excavator known as a mini excavator, which has a vehicle weight of 5 tons or less. The following describes the case where the protective cover is used with a mini excavator.

[0011] <Mini excavator 1 schematic configuration> The general configuration of the mini-excavator 1 will be described with reference to FIGS.

[0012] Fig. 1 is an external perspective view showing an example of the configuration of a mini-excavator 1 to which a protective cover 4 according to an embodiment of the present invention is applied. Fig. 2 is a view showing the mini-excavator 1 in a state in which the protective cover 4 is placed over the driving section 22.

[0013] The mini excavator 1 comprises a self-propelled crawler-type running body 11, a rotating body 12 rotatably attached above the running body 11, and a hydraulically driven front working device 13 attached to the front of the rotating body 12 for performing work such as excavation.

[0014] The running body 11 has a pair of crawlers 110 extending in the front-to-rear direction, and the pair of crawlers 110 rotate in contact with the ground by the driving force of a traveling motor to move the vehicle body. The pair of crawlers 110 are arranged side by side in the left-to-right direction of the vehicle body, and a traveling motor is mounted on each of the left and right sides of the running body 11 corresponding to each of the left and right crawlers 110. The left and right traveling motors can be driven independently, and the left and right crawlers 110 can be rotated forward and backward independently.

[0015] The revolving body 12 has a revolving frame 21, a driving section 22 that is placed on the revolving frame and on which an operator sits, a machine room 23 that is located behind the driving section 22 and houses equipment (for example, an engine, a hydraulic pump, etc.) for operating the mini excavator 1, and a counterweight 24 that is attached to the rear of the revolving frame 21 and maintains balance with the front working implement 13 to prevent the vehicle body from tilting.

[0016] Since the mini excavator 1 requires that the rotating body 12 be designed compactly, the driver's section 22 has a canopy structure in which the top of the driver's seat 223 is covered by a canopy 222 supported by support members 221 extending in the vertical direction, and the canopy structure is open on all sides.

[0017] The driver's section 22 is provided with a driver's seat 223 for the operator to sit in, as well as a pair of travel levers 224L, 224R for operating the traveling unit 11, and a pair of working levers 225L, 225R for operating the revolving unit 12 and the front working implement 13. The pair of travel levers 224L, 224R are arranged adjacent to each other in the left-right direction in front of the driver's seat 223. The pair of working levers 225L, 225R are arranged on both the left and right sides of the driver's seat 223.

[0018] Unlike a driver's compartment with a so-called cab structure, in which the driver's seat is located inside an enclosed space, the driver's section 22 with a canopy structure is always open to the outside (outdoors). Since the mini excavator 1 is often stored in a parked state outdoors at a work site or the like, the driver's section 22 is easily exposed to rain, snow, and the like and is easily covered in mud. Furthermore, the driver's section 22 may be damaged by flying debris, falling rocks, and the like during work.

[0019] For this reason, when the mini excavator 1 is stored outdoors, a sheet-like protective cover 4 is attached to the driver's section 22, as shown in Fig. 2. In this embodiment, the protective cover 4 is formed to a size that is large enough to cover the entire driver's seat 223 and the operating devices around the driver's seat 223, including the pair of travel levers 224L, 224R and the pair of work levers 225L, 225R. Furthermore, the protective cover 4 is secured by being tied to the running body 11 or the like with a rope 5, for example, to prevent it from being blown away by the wind.

[0020] The front working mechanism 13 has a boom 31 whose base end is rotatably attached to the revolving frame 21, a boom cylinder 31A that drives the boom 31, an arm 32 rotatably attached to the tip of the boom 31, an arm cylinder 32A that drives the arm 32, a bucket 33 rotatably attached to the tip of the arm 32, a bucket cylinder 33A that drives the bucket 33, and multiple pipes (not shown) that guide hydraulic oil to each of the cylinders 31A, 32A, 33A.

[0021] The boom 31 rotates vertically relative to the revolving frame 21 as hydraulic oil flows in and out of the boom cylinder 31A, causing the rod to extend and retract. The arm 32 rotates vertically relative to the boom 31 as hydraulic oil flows in and out of the arm cylinder 32A, causing the rod to extend and retract. The bucket 33 rotates vertically (crowds or dumps) relative to the arm 32 as hydraulic oil flows in and out of the bucket cylinder 33A, causing the rod to extend and retract.

[0022] <Configuration of protective cover 4> Next, a specific configuration of the protective cover 4 will be described with reference to FIGS.

[0023] Fig. 3 is a plan view showing an example of the configuration of the seat body 40. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3.

[0024] The protective cover 4 includes a flexible, rectangular sheet body 40. The sheet body 40 is formed, for example, from a single sheet of vinyl chloride material that is waterproof and UV-blocking. The shape of the sheet body 40 does not necessarily have to be rectangular, and it may be formed into any shape that corresponds to the specifications of the driver unit 22, such as a square, a quadrilateral with rounded corners (approximately a quadrilateral), or an oval.

[0025] The sheet body 40 is provided with two ridges 41, 42 that extend from one end to the other end in the width direction and protrude from one of the front and back surfaces of the sheet material. In this embodiment, the two ridges 41, 42 extend from one end to the other end in the short side direction of the sheet body 40 and are arranged side by side at a predetermined interval in the long side direction of the sheet body 40. In Fig. 3, the ridges 41, 42 are indicated by dashed lines.

[0026] In this embodiment, the ridges 41, 42 are formed by folding the sheet material from one end to the other end in the short side direction toward one side (one surface) in the thickness direction (the lower side in Fig. 4) and sewing the base of the fold as shown in Fig. 4. The ridges 41, 42 do not necessarily have to be formed by sewing, and may be formed by other methods such as bonding with an adhesive or joining with a hook-and-loop fastener.

[0027] Each of the protrusions 41, 42 becomes a crease when folding the sheet body 40. That is, each of the protrusions 41, 42 guides the sheet body 40 to be folded toward the surface (upper surface in FIG. 4) opposite to the surface from which it protrudes (lower surface in FIG. 4). Note that each of the protrusions 41, 42 may protrude from at least a portion of either the front or rear surface of the sheet material, as long as it is long enough to function as a crease in the sheet body 40.

[0028] Here, of the two ridges 41, 42, the ridge 41 shown on the left side in Fig. 3 is referred to as the "first ridge 41," and the other ridge 42 shown on the right side in Fig. 3 is referred to as the "second ridge 42." In addition, the surface shown in Fig. 3 (the upper surface in Fig. 4) is referred to as the "front surface" of the sheet body 40 (sheet material), and the surface not shown in Fig. 3 (the lower surface in Fig. 4) is referred to as the "back surface" of the sheet body 40 (sheet material).

[0029] In this embodiment, a pair of first magnets 431A and 431B are attached to the seat main body 40 on both sides of the first ridge 41, and a pair of second magnets 432A and 432B are attached to both sides of the second ridge 42. That is, the seat main body 40 has a pair of magnets 431A and 431B attached to the seat main body 40, which correspond to the first ridge 41. A pair of first magnets 431A and 431B are attached to the second ridges 42, and a pair of second magnets 432A and 432B are attached to the second ridges 42, respectively.

[0030] In Figure 3, the pair of first magnets 431A, 431B and the pair of second magnets 432A, 432B are both located at one end (upper side in Figure 3) of the short side direction of the sheet main body 40 (extension direction of each protrusion 41, 42), but this is not limited to this and there are no particular restrictions on their positions in the short side direction of the sheet main body 40.

[0031] The pair of first magnets 431A, 431B have opposite magnetic poles on the same side of the sheet main body 40, and are attracted to each other when the sheet main body 40 is folded along the first ridge 41. Similarly, the pair of second magnets 432A, 432B have opposite magnetic poles on the same side of the sheet main body 40, and are attracted to each other when the sheet main body 40 is folded along the second ridge 42. This will be described in detail below.

[0032] Of the pair of first magnets 431A, 431B, the first magnet 431A arranged on one side of the first protrusion 41 (left side in Figure 3) is referred to as "one first magnet 431A," and the first magnet 431B arranged on the other side of the first protrusion 41 (right side in Figure 3) is referred to as "the other first magnet 431B."

[0033] For example, if the magnetic pole of one first magnet 431A on the front side of the main sheet body 40 is an N pole, the magnetic pole of the other first magnet 431B on the front side of the main sheet body 40 is an S pole. That is, in this case, the magnetic pole of one first magnet 431A on the back side of the main sheet body 40 is an S pole, and the magnetic pole of the other first magnet 431B on the back side of the main sheet body 40 is an N pole.

[0034] Similarly, of the pair of second magnets 432A, 432B, the second magnet 432A arranged on one side of the second protrusion 42 (left side in Figure 3) will be referred to as "one second magnet 432A," and the second magnet 432B arranged on the other side of the second protrusion 42 (right side in Figure 3) will be referred to as "the other second magnet 432B."

[0035] For example, if the magnetic pole of one second magnet 432A on the front side of the main sheet body 40 is an N pole, the magnetic pole of the other second magnet 432B on the front side of the main sheet body 40 is an S pole. That is, in this case, the magnetic pole of one second magnet 432A on the back side of the main sheet body 40 is an S pole, and the magnetic pole of the other second magnet 432B on the back side of the main sheet body 40 is an N pole.

[0036] At this time, the magnetic pole of one first magnet 431A and the magnetic pole of one second magnet 432A become the same polarity (north pole on the front side and south pole on the back side) on the same side of the sheet main body 40, and the magnetic pole of the other first magnet 431B and the magnetic pole of the other second magnet 432B become the same polarity (south pole on the front side and north pole on the back side) on the same side of the sheet main body 40.

[0037] The four magnets 431A, 431B, 432A, 432B are arranged in a line from one side of the long side of the sheet body 40 to the other side (from left to right in Figure 3) in the order of one first magnet 431A (north pole on the surface side), one second magnet 432A (north pole on the surface side), the other first magnet 431B (south pole on the surface side), and the other second magnet 432B (south pole on the surface side).

[0038] Therefore, one second magnet 432A (with its north pole on the front surface) is placed between the pair of first magnets 431A and 431B, and the other first magnet 431B (with its south pole on the front surface) is placed between the pair of second magnets 432A and 432B.

[0039] If the magnetic pole of one of the second magnets 432A on the surface side of the sheet main body 40 is an S pole, when the sheet main body 40 is folded along the first protrusion 41, one of the first magnets 431A (with a N pole on the surface side) may be attracted to one of the second magnets 432A that is not paired with it, rather than the other paired first magnet 431B.

[0040] Similarly, if the magnetic pole of the other first magnet 431B on the surface side of the sheet main body 40 is a north pole, when the sheet main body 40 is folded along the second protrusion 42, the other second magnet 432B (with a south pole on the surface side) may be attracted to the other first magnet 431B that is not paired with it, rather than to the other second magnet 432A that is paired with it.

[0041] In this embodiment, by making the magnetic poles of the two magnets arranged on the same side of each protrusion 41, 42 the same poles on the same side of the seat main body 40, it is possible to prevent magnets that do not form a pair (specifically, one first magnet 431A and one second magnet 432A, and the other first magnet 431B and the other second magnet 432B) from sticking together when the seat main body 40 is folded.

[0042] 3, a plurality of mounting magnets 45 are provided in the peripheral region 400 of the seat main body 40. The plurality of mounting magnets 45 are attracted to magnetic members M among the plurality of constituent members that make up the mini excavator 1, thereby detachably attaching the seat main body 40 to the mini excavator 1. The magnetic members M are constituent members that are mainly made of iron plate, such as the swivel frame 21 and the cover of the machine room 23.

[0043] As mentioned above, the protective cover 4 is fixed to the running body 11 by a plurality of ropes 5 (see Figure 2), and is further fixed to the rotating frame 21, the cover of the machine room 23, etc. by a plurality of mounting magnets 45, so that the protective cover 4 is less likely to come off the operating section 22 even in the event of a strong wind.

[0044] In addition, since multiple grommets 44 for passing multiple ropes 5 are formed at predetermined intervals in the peripheral region 400 of the sheet body 40, each of the multiple mounting magnets 45 is positioned in the region between adjacent grommets 44.

[0045] In addition, the multiple mounting magnets 45 may be attached directly to the peripheral region 400 of the seat body 40, or may be movably arranged within a storage space formed in the peripheral region 400 by stacking two sheets of sheet material.

[0046] Furthermore, in this embodiment, the protective cover 4 is fixed to the mini excavator 1 by a plurality of ropes 5 and a plurality of mounting magnets 45, but this is not limited to this, and the protective cover 4 may be fixed to the mini excavator 1 by only a plurality of ropes 5 or only a plurality of mounting magnets 45.

[0047] <How to store the protective cover 4> Next, a method for storing the protective cover 4 will be described with reference to FIGS.

[0048] Fig. 5 is an explanatory diagram illustrating how the seat body 40 is folded. Fig. 6 is a diagram showing the protective cover 4 in a state where it is stored behind the driver's seat 223. Note that Fig. 5 shows a simplified version of the seat body 40 shown in Fig. 3.

[0049] When the sheet body 40 is viewed from the front side, the region to the left of the first ridge 41 is the first region X, the region between the first ridge 41 and the second ridge 42 is the second region Y, and the region to the right of the second ridge 42 is the third region Z.

[0050] First, the worker folds the first region X of the seat main body 40 toward the second region Y along the first protrusion 41 (the middle state shown in FIG. 5). As a result, the seat main body 40 is folded in half, with the front surface of the first region X facing the front surface of the second region Y and the back surface of the first region X coming outward (exposed to the outside). Then, one first magnet 431A is attracted to the other paired first magnet 431B, thereby maintaining the first region X in its folded state (folded in half).

[0051] Next, the worker folds the third region Z of the seat main body 40 toward the second region Y along the second protrusion 42 (the state shown in the lower part of FIG. 5). As a result, the seat main body 40 is folded in three, with the front surface of the second region Y facing the back surface of the first region X and the back surface of the second region Y coming outward (exposed to the outside). Then, one second magnet 432A is attracted to the other second magnet 432B with which it is paired, thereby maintaining the third region Z in its folded state (the state folded in three).

[0052] 5 is merely an example, and the seat body 40 does not necessarily have to be folded from the first region X; for example, the seat body 40 may be folded from the third region Z.

[0053] In this way, the first ridges 41 and the second ridges 42 each serve as folds in the main seat body 40, allowing the worker to easily and compactly fold a large main seat body 40 having a width of at least 1 meter. Furthermore, the paired magnets (the pair of first magnets 431A, 431B and the pair of second magnets 432A, 432B) attract each other, so the main seat body 40 remains neatly folded and becomes even more compact.

[0054] The seat body 40 is naturally folded by the guidance of the ribs 41, 42 so that the surface on which the ribs 41, 42 do not protrude faces inward and the back surface on which the ribs 41, 42 protrude faces outward. Therefore, when hanging the seat body 40 on the driver's section 22, if the surface faces outward (exposed to the outside), the worker can fold the seat body 40 while it is still hanging on the driver's section 22, making storage easier.

[0055] The protective cover 4 further includes a pair of fixing bands 46 for fixing the seat body 40. The seat body 40, which has been folded in thirds along the long side, is rolled up from one end side along the short side to form a compact structure, and is fixed with the pair of fixing bands 46. The pair of fixing bands 46 may be separate from the seat body 40, as in this embodiment, or may be attached to the seat body 40 in advance.

[0056] As shown in FIG. 6, the seat body 40, i.e., the protective cover 4, fixed by a pair of fixing bands 46 is stored, for example, in an empty space behind the driver's seat 223, when not in use.

[0057] <Modification> Next, a protective cover 4A according to a modified example of the present invention will be described with reference to FIGS.

[0058] Fig. 7 is a plan view showing an example of the configuration of a protective cover 4A according to a modified example. Fig. 8 is an explanatory diagram illustrating how the sheet main body 40 according to the modified example is gathered and stored in a storage bag 47. Note that in Figs. 7 and 8, components that are common to those described for the protective cover 4 according to the embodiment are assigned the same reference numerals, and descriptions thereof will be omitted.

[0059] The protective cover 4 according to this modification includes a seat body 40 and a storage bag 47 as a storage member for removably storing the assembled seat body 40. As shown in Fig. 7, a pair of fixing bands 46A and the storage bag 47 are attached to one end of the seat body 40 in the short side direction (the lower side in Fig. 7).

[0060] In Figure 7, the pair of fixing bands 46A and the storage bag 47 are attached to the end opposite to the end on which the pair of first magnets 431A, 431B and the pair of second magnets 432A, 432B are arranged, but this is not limited to this and they may be attached to the end on which the pair of first magnets 431A, 431B and the pair of second magnets 432A, 432B are arranged.

[0061] When the seat body 40 is folded in three, the back surface faces outward, and since the seat body 40 is rolled up in this state, as shown in Fig. 8, the pair of fixing bands 46A and the storage bag 47 are attached to the back surface of the seat body 40. Note that, unlike Fig. 3, Fig. 7 shows the back surface of the seat body 40 (the surface from which the protrusions 41, 42 protrude).

[0062] In this modified example, the storage bag 47 is a drawstring bag. As shown in Fig. 8, the gathered sheet bodies 40 are stored in the storage bag 47 after being fixed with a pair of fixing bands 46A.

[0063] Furthermore, in this modified example, two fixing magnets 470 are attached to the storage bag 47. These two fixing magnets 470 are attracted to the magnetic member M that constitutes the mini excavator 1. This makes it possible to fix the main seat body 40 stored in the storage bag 47, i.e., the protective cover 4A according to this modified example, to the mini excavator 1.

[0064] Therefore, there is no need to secure a separate space for storing the protective cover 4A in the mini excavator 1. Furthermore, it is possible to prevent the stored protective cover 4A from moving somewhere other than the storage space while the mini excavator 1 is operating.

[0065] It is not necessary to attach two fixing magnets 470, and there are no particular restrictions on the size or number of magnets as long as they can firmly fix the protective cover 4A to the mini-excavator 1.

[0066] The above describes the embodiments and modifications of the present invention. Note that the present invention is not limited to the above-described embodiments and modifications, and various other modifications are also included. For example, the above-described embodiments and modifications have been described in detail to clearly explain the present invention, and are not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of this embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of this embodiment. Furthermore, it is possible to add, delete, or replace part of the configuration of this embodiment with other configurations.

[0067] For example, in the above embodiment and modified examples, a mini excavator 1 has been used as an example of a work machine to which the protective covers 4, 4A are applied, but the invention is not limited to this and may be applied to other work machines such as a wheel loader or a dump truck.

[0068] Furthermore, in the above embodiment and modified example, two protrusions 41, 42 are provided on the seat main body 40, but this is not limited to this, and the number of protrusions provided on the seat main body 40 (at least one) may be determined according to the size and shape of the seat main body 40.

[0069] Similarly, in the above embodiment and modified example, two sets of pairs of magnets 431A, 431B, 432A, 432B are provided on the seat main body 40, but this is not limited to this, and the number of pairs of magnets provided may be any number corresponding to the number of protrusions.

[0070] Furthermore, there are no particular limitations on the shape and size of the pair of first magnets 431A, 431B, the pair of second magnets 432A, 432B, the plurality of mounting magnets 45, and the plurality (two) of fixing magnets 470. [Explanation of symbols]
