[Technical Field]
[0001] The present invention relates to a falling object receiving net, and more particularly to a falling object receiving net used when removing bird nests, etc., built on utility poles, etc. [Background technology]
[0002] The falling object receiving net comprises a roughly square mesh-like main net that is supported by supports attached to cross arms attached to utility poles, and a band-like mesh-like subnetwork that is connected to the main net at one end and attached at the other end to the bucket of an aerial work vehicle (see Patent Document 1).
[0003] The support device has two arms fixed to each end of the arm in the longitudinal direction with the arms open at a predetermined angle, and the tips of the four arms are engaged with the four corners of the main net via hooks, thereby supporting the main net. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-205324 Summary of the Invention [Problem to be solved by the invention]
[0005] In the configuration of Patent Document 1, it is necessary to attach a support device with four arms to the arm bracket and then engage the tips of the four arms with the main net, which has the inconvenience of taking a long time to attach the net, and early improvement is desired.
[0006] In view of the above problems, the present invention aims to provide a falling object catch net that can be installed easily and quickly. [Means for solving the problem]
[0007] The falling object receiving net of the present invention comprises a flexible, approximately rectangular mesh body, one end of which is connected to the bucket of an aerial work vehicle, and a fixing means for fixing the other end of the mesh body to the utility pole so as to stretch the mesh body between the bucket and the utility pole.
[0008] According to the above configuration, one end of the mesh body is connected to the bucket of the aerial work vehicle and the other end of the mesh body is fixed to the utility pole using a fixing means, so that the mesh body can be stretched between the bucket of the aerial work vehicle and the utility pole, making it easy and quick to install the mesh body.
[0009] In addition, the falling object receiving net of the present invention may have a fixing means that includes a support member that extends in the width direction of the mesh body and connects and supports the other end of the mesh body, and a band-shaped body that is attached to the support member and wrapped around the utility pole to fix the support member.
[0010] As described above, by wrapping the band provided on the support member that connects and supports the other end of the mesh around the utility pole, the other end of the mesh can be fixed to the utility pole via the support member.
[0011] In addition, the falling object receiving net of the present invention may be configured so that the fixing means is capable of selecting between a proximal fixing mode in which the support member is positioned closer to the bucket relative to the utility pole and the band is wrapped around it, and a distal fixing mode in which the support member is positioned farther from the bucket relative to the utility pole and the band is wrapped around the utility pole.
[0012] According to the above configuration, it is possible to select the optimum fixing mode (proximal fixing mode or distal fixing mode) depending on the on-site conditions, such as the mounting condition on the utility pole and the nesting condition.
[0013] In addition, the falling object receiving net of the present invention may have a plurality of rings provided along the width direction at the other end of the mesh body, and the support member may include a rod-shaped member that extends along the width direction of the mesh body, and a plurality of engaging portions that are provided on the rod-shaped member so as to be positioned corresponding to the width direction positions of the plurality of rings, and that can be engaged with and disengaged from the plurality of rings.
[0014] As described above, by supporting the mesh body on a rod-shaped member, the mesh body can be easily expanded, and by engaging the ring with the engaging portion, the mesh body can be supported on the rod-shaped member, making it easy to attach the mesh body.
[0015] Furthermore, the falling object receiving net of the present invention may be configured such that the other end of the mesh body is configured to be separable into two branches on one side and the other side in the width direction, the other end of the mesh body is provided with a plurality of rings along the width direction, the support member is provided with a plurality of locking portions that can be locked and unlocked from the plurality of rings so as to correspond to the plurality of rings, and when the utility pole is sandwiched between the separated mesh body on one side and the mesh body on the other side, the ring located at the separated side end of the mesh body on one side is locked with the locking portion provided on the support member that corresponds to the ring located at the separated side end of the mesh body on the other side, and the ring located at the separated side end of the mesh body on the other side is locked with the locking portion provided on the support member that corresponds to the ring located at the separated side end of the mesh body on one side.
[0016] The other end of the mesh body is split into two parts in the width direction, one on one side and the other on the other side, and the utility pole is sandwiched between the split mesh body on one side and the other on the other side.The ring located at the split end of the mesh body on one side is engaged with a locking portion provided on a support member corresponding to the ring located at the split end of the mesh body on the other side, and the ring located at the split end of the mesh body on the other side is engaged with a locking portion provided on a support member corresponding to the ring located at the split end of the mesh body on one side.By crossing the split end of the mesh body on the other side and the split end of the mesh body on one side, the mesh body can be positioned around the utility pole while preventing gaps from occurring between the utility pole and the split ends of the two mesh bodies, and falling objects can be reliably caught.
[0017] In addition, in the falling object reception net of the present invention, the support member may further include a locking member that can be locked and unlocked from a scaffolding bolt provided on the utility pole.
[0018] As described above, by engaging the locking member provided on the support member with the scaffolding bolt, even if the fixing means loosens, the support member fixed to the utility pole can be prevented from moving downward unexpectedly. [Effects of the Invention]
[0019] As described above, according to the present invention, by fixing one end of a mesh body connected to the bucket of an aerial work vehicle to a utility pole using a fixing means, the mesh body can be stretched between the bucket of the aerial work vehicle and the utility pole, thereby providing a falling object receiving net that can be installed easily and quickly.

[0021] First Embodiment A first embodiment of a falling object receiving net according to the present invention will be described with reference to the drawings. The falling object receiving net 1 shown in Fig. 3 comprises a mesh body 3 (see Fig. 1) having one end (base end) connectable to a bucket 2 of an aerial work vehicle, and a fixing means 5 (see Fig. 2) for fixing the other end (tip end) of the mesh body 3 to a utility pole 4. In Fig. 3, the bucket 2 side is the base end side, the utility pole 4 side is the tip end side, the width direction perpendicular to the longitudinal direction of the mesh body 3 is the left-right direction, and the height direction of the utility pole 4 is the up-down direction, and the following description will be given (the same applies to Fig. 6).
[0022] The mesh body 3 is made of synthetic resin, cloth, nonwoven fabric, etc. to provide flexibility. As shown in Fig. 1, the left and right corners of the base end have inwardly curved recessed portions 3A, 3A. The left and right dimensions increase from the distal ends of these recessed portions 3A, 3A to the distal end of the mesh body 3, giving it a so-called apron-shaped (substantially rectangular) outer shape, but it may also be rectangular (square or oblong). The base end and distal end of the mesh body 3 are linearly oriented in the width direction. While Fig. 1 shows the left and right corners of the base end of the mesh body 3 having inwardly curved recessed portions 3A, 3A, the left and right corners of the base end of the mesh body 3 may also be linearly shaped by cutting them diagonally.
[0023] As shown in Figures 1 and 3, the left and right ends of the base end of the mesh body 3 are provided with multiple (two in this embodiment) metal rings (eyelets) 7, 7 that can be engaged with and disengaged from a pair of S-shaped hooks 6, 6 that serve as engaging portions provided on the handrail 2A at the tip side of the bucket 2. Furthermore, a general-purpose slide fastener 8 is provided in the approximate center in the left-right direction of the tip end of the mesh body 3, extending from the base end to the tip end. By moving a slider (not shown), a pair of interlocking fastener elements (not shown) can be separated, thereby separating the tip end of the mesh body 3 into two bifurcated sides in the left-right (width) direction. The slide fastener 8 constitutes an opening / closing means for separating the tip end of the mesh body 3 into one side and the other side in the left-right (width) direction, or for integrating the separated sides. The length from the tip to the base end of the slide fastener 8 is shorter than half the length (total length) from the tip to the base end of the mesh body 3, and the base end of the slide fastener 8 is located closer to the tip than half the length (total length) from the tip to the base end of the mesh body 3.
[0024] In addition, a total of four metal rings (eyelets) 9A, 9B, 9C, and 9D are provided on both the left and right sides of the two corners at the tip of the mesh body 3 and the slide fastener 8. Furthermore, at each of the left and right ends and base end of the mesh body 3, string-like bodies 10 are threaded from the base end to the tip of the mesh body 3 and connected and fixed by, for example, strings at multiple locations in the longitudinal direction of the mesh body 3 (four locations indicated by black circles (●) in Figure 1, but any number of locations, such as one or more, may be used). Furthermore, metal rings (eyelets) 11, 11 are connected (fixed) to the base ends of the string-like bodies 10, 10 that pull the left and right ends of the mesh body 3. Because the rings (eyelets) 11, 11 are located closer to the tip and further outward in the left-right direction than the rings (eyelets) 7, 7, by engaging the rings (eyelets) 11, 11 (described later) with the hooks 6, both left and right ends of the net body 3 are pulled toward the base end and the inner portion of the net body 3 in the left-right direction can be loosened. Therefore, as the rings (eyelets) 11, 11 at both left and right ends of the net body 3 move from the tip end to the base end and from the outer side to the inner side in the left-right direction, both left and right ends of the net body 3 become taut and the central portion of the net body 3 becomes slack. As a result, the central portion of the net body 3 hangs down under its own weight to form a bottom, and the net body 3 becomes structured (so-called hammock-shaped) to catch falling objects (in this embodiment, a bird's nest T). Moreover, because the tip of the net body 3 can be kept taut horizontally by the support member 51 (described later), the net body 3 can be taut at three sides, including the tip and both left and right ends of the net body 3. This makes it easier for only the central portion of the mesh body 3 to sag under its own weight. Note that each of the left and right (width) end portions of the mesh body 3 is folded back to form a tunnel, and the string-like body 10 is passed through the formed tunnel and then connected and fixed to the mesh body 3 by, for example, a string. Also, the string-like body 10 is connected and fixed to the mesh body 3 in a state where it is passed from the base end to the tip end of the mesh body 3, but the string-like body 10 may also be connected and fixed to the base end of the mesh body 3.
[0025] The fixing means 5 includes a support member 51 that extends in the width direction (left-right direction) of the mesh body 3 and connects and supports the tip of the mesh body 3, and a strip-shaped body 52 that is attached to the support member 51 and wrapped around the utility pole 4 to fix the support member 51 to the utility pole 4.
[0026] 2 and 3, the support member 51 is made of a rod-shaped member extending in the width direction (left-right direction) of the mesh body 3, and has a plurality of locking portions 51A, 51B, 51C, and 51D in the width direction (four in FIG. 2, the same number as the rings 9A to 9D) that can be locked to and unlocked from four rings 9A, 9B, 9C, and 9D provided at the tip of the mesh body 3. Each of the locking portions 51A, 51B, 51C, and 51D is connected to a string 51E that is wound around and fixed to the support member 51. Note that the string 51E may be replaced with a wire, a linear rod, a connecting metal fitting, or the like. By supporting the mesh body 3 on a rod-shaped member (support member 51), the mesh body 3 can be easily spread out, and by engaging the rings 9A, 9B, 9C, and 9D with the engaging portions 51A, 51B, 51C, and 51D, the mesh body 3 can be supported on the rod-shaped member (support member 51), making it easy to attach the mesh body 3.
[0027] Each locking portion 51A is positioned at approximately the same position in the left-right (width) direction as each ring 9A and is composed of a carabiner (fastener). As shown in Figure 2, each carabiner includes a substantially C-shaped carabiner body 51a and a gate 51b provided at one end of the carabiner body 51a to open and close the gate 51b to the other end of the carabiner body 51a. As shown in Figure 2, to lock the carabiner to the ring 9D, the gate 51b is opened (see the locking portion 51D at the right end in Figure 2), the other end 51c of the carabiner body 51a is inserted into the ring 9D (see Figure 3), and then the gate 51b is closed to lock and secure the locking portion 51A to the ring 9D.
[0028] 4 and 5, the band-shaped body 52 is composed of a general-purpose ratchet-type lashing belt having a pair of belts 52A, 52A wound around the utility pole 4 and a ratchet buckle (not shown) for tightening the belts 52A, 52A to the utility pole 4 by pulling one of the belts 52A. The base ends of the belts 52A, 52A are inserted and held in belt insertion portions 53A, 53A of a belt mounting member 53 integrated with the outer surface of a cylindrical member 55 externally fitted and fixed to the center of the support member 51 in the left-right direction.
[0029] 2(a), (b), 4, and 5, the support member 51 further includes a locking member 54 that can lock and unlock with a scaffolding bolt 12 attached to the utility pole 4. The locking member 54 extends upward from the upper end of the support member 51 and is composed of a plate-like member with an upper end curved in an arc. The locking member 54 is formed with a first through hole 54A having a size that allows the head 12A of the scaffolding bolt 12 to be inserted therein, and a second through hole 54B that communicates with the upper end of the first through hole 54A and has a smaller diameter than the first through hole 54A so that only the shank 12B of the scaffolding bolt 12 inserted through the first through hole 54A is locked.
[0030] The falling object receiving net 1 configured as described above is used, for example, when removing a bird's nest T that has been built on a pair of cross arms 13, 13 provided on a utility pole 4, as shown in FIG.
[0031] The procedure for installing the falling object catch net 1 will be described below. First, a pair of rings 7, 7 at the base end of the mesh body 3 is locked onto a pair of hooks 6, 6 on the bucket 2. Next, a support member 51 is positioned closer to the base end (nearer) than the utility pole 4 and at approximately the same height as the pair of hooks 6, 6 on the bucket 2, and then a locking member 54 provided on the support member 51 is locked onto a footing bolt 12 to temporarily secure the support member 51. After the temporary locking, a pair of belts 52A, 52A are wrapped around the utility pole 4 and tightened to firmly secure the support member 51 to the utility pole 4. After the locking, the bucket 2 is moved closer to the utility pole 4, and locking portions (carabiners) 51A, 51B, 51C, 51D, which are located at approximately the same widthwise position, are locked onto four rings 9A, 9B, 9C, 9D provided at the tip of the mesh body 3, thereby connecting the tip of the mesh body 3 to the support member 51. After the connections are made, the bucket 2 is moved away from the utility pole 4, and the rings 11, 11 provided at the base ends of the string-like bodies 10, 10 are engaged with the pair of hooks 6, 6 of the bucket 2, thereby pulling the left and right ends of the net-like body 3 (putting the left and right ends in a taut state) and loosening the central portion of the net-like body 3. As a result, the central portion of the net-like body 3 hangs down under its own weight to form a bottom, forming a structure (a so-called hammock shape) that catches falling objects (in this embodiment, bird's nests T), and the installation of the falling object reception net 1 is completed (see FIG. 3). After the falling object reception net 1 is installed, the bird's nest T is dropped onto the net-like body 3 of the falling object reception net 1 using a stick or the like and collected.
[0032] Second Embodiment Next, a second embodiment of a falling object reception net according to the present invention will be described. The components constituting the falling object reception net 1 are the same as those in the first embodiment, but the position of the support member 51 relative to the utility pole 4 when the support member 51 is fixed to the utility pole 4 is different. The slide fasteners 8 are opened to bifurcate the mesh body 3 and sandwich the utility pole 4. In the first embodiment, because the bird's nest T is located closer to the front of the utility pole 4, the support member 51 is positioned closer to the base end (nearer) of the utility pole 4. In other words, the support member 51 is positioned closer to the bucket 2 with a pair of belts 52A, 52A wound around it to be fixed to the utility pole 4 in a proximal fixing manner. In contrast, as shown in FIG. 6, when the bird's nest T is closer to the utility pole 4, the support member 51 is positioned further back (tip) than the utility pole 4. In other words, the support member 51 is positioned farther from the bucket 2 with a pair of belts 52A, 52A wound around it to be fixed to the utility pole 4 in a distal fixing manner. This allows the bird's nest T to be reliably received by the net-like body 3. Therefore, in order to position the support member 51 further back (toward the tip) than the utility pole 4, the support member 51 is positioned in a position rotated 180° about the vertical axis from the state shown in FIG. 3 so that the pair of belts 52A, 52A and the belt attachment member 53 provided on the support member 51 face the base end side (see FIG. 8). In short, the optimum fixing mode (either the proximal fixing mode or the distal fixing mode) can be selected depending on the on-site conditions, such as the mounting status on the utility pole 4 and the nesting conditions (nesting position conditions).
[0033] When installing the falling object reception net 1, first, the rings 7, 7 at the base end of the mesh body 3 are engaged with the pair of hooks 6, 6 of the bucket 2 (see FIG. 6). Next, the support member 51 is positioned further forward (rearward) than the utility pole 4 and at approximately the same height as the pair of hooks 6, 6 of the bucket 2, and then the locking members 54 provided on the support member 51 are engaged with the scaffolding bolts 12 to temporarily secure the support member 51 (see FIG. 8). After the temporary securing, the pair of belts 52A, 52A are fastened to the utility pole 4 to firmly secure the support member 51 to the utility pole 4 (see FIG. 8). After securing, the slide fasteners 8 are released to bifurcate the mesh body 3, and the bucket 2 is then moved closer to the utility pole 4, so that the utility pole 4 is sandwiched between the separated first mesh body 31 on one side and the second mesh body 32 on the other side. Of the four rings 9A, 9B, 9C, and 9D provided at the tip of the mesh body 3, two locking portions (carabiners) 51A and 51D located at approximately the same position in the width direction are locked onto the rings 9A and 9D located at both the left and right ends (see FIG. 6). Next, of the remaining two rings, ring 9B located at the separation side end of the first mesh body 31 on one side is locked onto locking portion (carabiners) 51C corresponding to ring 9C located at the separation side end of the second mesh body 32 on the other side, and ring 9C located at the separation side end of the second mesh body 32 on the other side is locked onto locking portion (carabiners) 51B corresponding to ring 9B located at the separation side end of the first mesh body 31 on one side. As a result, by crossing the separated side end of the second mesh body 32 on the other side with the separated side end of the first mesh body 31 on one side (see Figures 6 and 7), the mesh body 3 can be arranged around the utility pole 4 while preventing gaps from occurring between the utility pole 4 and the separated side ends of the two separated mesh bodies 31, 32, and falling objects can be reliably caught (see Figures 6 and 7). In this way, the tip of the mesh body 3 is connected to the support member 51. After connection, the bucket 2 is moved away from the utility pole 4, and then the rings 11, 11 provided at the base ends of the string-like bodies 10, 10 are engaged with the pair of hooks 6, 6 of the bucket 2, thereby pulling the left and right ends of the mesh body 3 (keeping the left and right ends taut) and slackening the central portion of the mesh body 3.As a result, the central portion of the mesh body 3 hangs down under its own weight to form a bottom, forming a structure (so-called hammock-like) that catches falling objects (bird's nests T in this embodiment), completing the installation of the falling object reception net 1 (see Figure 6). After the falling object reception net 1 is installed, the bird's nest T is dropped onto the mesh body 3 of the falling object reception net 1 using a stick or the like and collected. Note that Figures 6 and 7 omit the belt mounting member 53, cylindrical member 55, and belts 52A, 52A that are provided in the center of the support member 51 in the left-right direction.
[0034] The falling object receiving net according to the present invention is not limited to the above embodiment and can be modified in various ways.
[0035] In the first and second embodiments, the locking portions (carabiners) 51A-51D are fixed to the support member 51 by a string 51E so that their positions cannot be changed in the left-right direction. However, as shown in FIGS. 9(a) and 9(b), a position change means may be provided that allows the position of the locking portion (carabiners) 51A to be changed in the left-right direction on the support member 51. The position change means includes a plurality of recesses 51H formed at intervals in the width direction of the support member 51, an annular movable member 14 mounted on the support member 51 so as to be movable in the width direction, and a fixing pin 15 for fixing the movable member 14 to the support member 51 by inserting it into a specific recess 51H of the support member 51. Furthermore, the locking portion (carabiners) 51A may be attached to a shaft 16 protruding downward from the lower end of the movable member 14 so as to be rotatable about the vertical axis X. Note that, instead of the recesses 51H and the pins 15, a screw hole and a screw that can be threaded and unthreaded into the screw hole may be provided.
[0036] Furthermore, in the first and second embodiments, the base end side of the mesh body 3 is configured to be able to be released from engagement with the hooks 6, 6 of the bucket 2, but the base end side of the mesh body 3 may also be connected and fixed to the bucket 2. In this case, the bucket 2 may be provided with a storage section for storing the mesh body 3 when the mesh body 3 is not in use.
[0037] Furthermore, in the first and second embodiments, the support member 51 fixed to the utility pole 4 is connected to the tip of the mesh body 3, but the support member 51 may be fixed to the utility pole 4 after the support member 51 and the tip of the mesh body 3 are connected.
[0038] Furthermore, in the first and second embodiments, a slide fastener is used to make the other end of the mesh body 3 separable into two parts, but a hook-and-loop fastener, a button, a hook, or the like may also be used.
[0039] Furthermore, in the first and second embodiments, a carabiner that will not be unexpectedly released from a locked state is used as the locking portion, but a hook may also be used.
[0040] Furthermore, in the first and second embodiments, the support member 51 is provided with the locking member 54 that can be locked to and unlocked from the foothold bolt 12 provided on the utility pole 4, but the locking member 54 may be omitted. [Explanation of symbols]
