  The fallen object collection apparatus 1 includes an umbrella part 10 having a structure similar to a general rain umbrella and a collection container 50 attached to the tip of the umbrella part 10. The fallen object collecting apparatus 1 receives the fallen object by the umbrella part 10 suspended in an inverted umbrella shape in an open state, and further collects the fallen object received by the umbrella part 10 by guiding it to the lower collection container 50. There is a feature. In the following description, “open umbrella” means that the umbrella portion 10 is open, and “closed umbrella” means that the umbrella portion 10 is closed.

<Basic structure and operation of umbrella>
The umbrella part 10 has a hanging tool 40 at one end, a middle bar 11 having a collection container attaching / detaching part 11a at the other end, a main bone support member 13 fixed at a position near the other end part of the middle bar 11, A bone support member 15 attached to the middle part of the rod 11 so as to be axially movable, a plurality of master bones 17 whose one ends 17 a are swingably attached to the master bone support member 13, and one end 19 a of each master bone 17. The other ends 19b of the bone receiving support members 15 are swingably attached to the intermediate portion of the bone receiving member 19, and are supported between the parent bones 17 and around the middle rod 11. And a falling object collecting sheet 21 having an opening 22 formed therein.
The main bone support member 13 and the bone receiving support member 15 have a substantially cylindrical shape, and the middle rod 11 is inserted through each hollow portion. The main bone support member 13 supports the main bone 17 arranged radially with respect to the middle rod 11, and the bone receiving support member 15 supports the bone receiving bone 19 arranged radially with respect to the middle rod 11.

As shown in FIGS. 1 and 3, when the bone receiving support member 15 is moved from one end portion to the other end portion of the intermediate rod 11, the main bone 17 is expanded by the receiving bone 19 and the fallen object collecting sheet 21. Opens. On the contrary, when the bone receiving support member 15 is moved from the other end portion of the intermediate rod 11 toward the one end portion, the main bone 17 is gathered together along the intermediate rod 11 by the receiving bone 19, and the falling object collecting sheet 21 is collected. Closes. Thus, the umbrella part 10 changes the attitude | position between the open state which the falling object collection sheet | seat 21 opened, and the closed state which the falling object collection sheet | seat 21 closed.
The number of the main bones 17 and the ribs 19 is such that there is a gap through which falling objects such as bird nesting materials and garbage can pass toward the collection container 50 and the shape of the umbrella portion 10 can be maintained. Is set.
It is desirable that the middle rod 11 and each bone (the parent bone 17 and the receiving bone 19) constituting the umbrella portion 10 are made of lightweight, strong against corrosion such as rust, and strong material such as stainless steel or fiber reinforced plastic. .

<Falling object collection sheet>
The falling object collecting sheet 21 is a part that receives the falling object on the surface (one surface) facing the middle rod 11 when closed and guides the received falling object to the collection container 50. The falling material collection sheet 21 is made of a material having high strength against pulling and abrasion. The falling object collecting sheet 21 can be composed of various materials such as a synthetic fiber cloth, a sheet made of a synthetic resin such as polyvinyl chloride, or a natural fiber cloth, but a nylon material is particularly preferable. The falling material collecting sheet 21 may be a mesh material having a large number of holes. In this case, the diameter of the mesh is such that the falling material to be received does not pass from the portion other than the opening 22 to the other surface side. Need to be set.
The opening 22 of the falling object collecting sheet 21 is a part that allows the falling object received on one surface of the falling object collecting sheet 21 to pass to the other surface side (the collection container 50 side). The magnitude | size of the opening part 22 is suitably set according to the magnitude | size of the fallen object which should be collect | recovered. The shape of the opening 22 can be a circular shape, a polygonal shape, or any other shape.

As shown in FIG. 2, the falling object collecting sheet 21 is formed by joining a plurality of sheet pieces 23, 23,. Of course, the falling object collecting sheet 21 may be composed of a single sheet-like member. The joining portion 24 of the falling object collecting sheet 21 shown in FIG. 2 extends along the main bone 17. The joint 24 may be configured not to be openable (or not separable) or may be configured to be openable (or separable).
The falling object collecting sheet 21 includes a cut line 25 formed from the peripheral edge 21a to the opening 22 and a clip 26 that allows the cut line 25 to be opened and closed and to be kept closed. The number of the cut lines 25 formed in the falling object collecting sheet 21 may be single or plural. The cut line 25 shown in this example is formed using the joint portion 24. Note that the cut line 25 may be formed at any part of the fallen object collecting sheet 21 other than the joint portion 24.

  The fastener 26 only needs to be able to join the two sheet pieces 23 and 23 so as not to form a gap having a size that allows a fallen object to be received to pass therethrough. The clasp 26 is only required to be able to keep the cut line 25 closed (joined) and to be able to temporarily open the cut line 25 (temporarily cut off). In addition, buttons, hooks, and the like can be used. When the cutting line 25 is closed by the fastener 26, the falling object collecting sheet 21 collects the falling object as a whole.

  In the illustrated example, the sheet piece 23A located between the two main bones 17A and 17B is not integrated with any of the main bones 17A and 17B, and the adjacent sheet pieces 23B and 23B are integrated with the fastener 26. Has been. Moreover, the fastener 26 consists of a wire fastener, and it is comprised so that the cut line 25 can be open | released toward the opening part 22 from the peripheral edge 21a.

4A and 4B are diagrams illustrating a usage state of the falling object collecting apparatus in which a part of the falling object collecting sheet is opened, FIG. 4A is a perspective view, and FIG. 4B is a diagram in which FIG. It is.
As shown in FIG. 4, when at least a part of the two cut lines 25 is opened from the peripheral edge 21a and at least a part of the sheet piece 23A is cut off from the sheet piece 23B, the utility pole 100 is interposed between the adjacent main bones 17 and 17. And steel tower steel materials can be inserted. If a falling object recovery device without a cut line is to be attached to the utility pole 100, the widely-opened fall object collecting sheet 21 has a peripheral edge 21a that interferes with the utility pole 100 and the falling object recovery device is installed straight. The fallen object cannot be guided to the collection container 50 successfully. According to the present embodiment, by forming the cut line 25 in the falling object collecting sheet 21, the falling object collecting apparatus 1 can be installed straight without interfering with the utility pole 100 or the like. Even if there are other obstacles, the fallen object can be efficiently recovered in the recovery container 50.

Furthermore, the fall object collection | recovery apparatus 1 can surround the circumference | surroundings half around the utility pole 100 by opening the cut line 25 and inserting the utility pole 100 between the main bones 17A and 17B. In particular, when the peripheral edge 21a side of the fastener 26 is partially opened, the falling object collecting sheet 21 is brought into close contact with the side surface of the utility pole 100 by its slack as shown in FIGS. 4 (a) and 4 (b). Therefore, the fallen object that falls along the side surface of the utility pole 100 can be collected.
On the outer surface (other surface) of the falling object collecting sheet 21, an eyeball pattern 27 for repelling harmful birds is attached. Birds in the breeding season become very aggressive, and there is a risk that workers involved in nesting will be attacked when ascending to the tower. In such a case, by opening the fallen object recovery apparatus 1 toward the harmful bird, the eyeball pattern 27 is opened widely, and the harmful bird can be driven away.

<Stopper>
A stopper that maintains the master bone in a fully open state, an intermediate open state, or a fully closed state will be described. 5A and 5B are cross-sectional views of the intermediate rod, wherein FIG. 5A shows a fully open stopper portion, FIG. 5B shows an intermediate stopper portion, and FIG. 5C shows a fully closed stopper portion.

When the bone receiving support member 15 is locked by any of the intermediate stoppers 33, the master bone 17 is opened at an opening degree corresponding to the position of the bone receiving support member 15.

The fully closed stopper 35 is an opening prevention stopper that keeps the bone receiving support member 15 immovable in a state where the main bone 17 is fully closed by locking the bone receiving support member 15 in the locked hole 16. As shown in FIG. 5 (c), the fully closed stopper 35 is formed of a leaf spring and is incorporated in the hollow interior of the intermediate rod 11. The claw portion 35a of the fully closed stopper 35 that locks the bone receiving support member 15 is in a biased state that is always exposed from the slit 36 formed on the side surface of the intermediate rod 11.
As for the shape along the axial direction of the claw portion 35a of the fully closed stopper 35, one end side in the axial direction is substantially perpendicular to the middle rod 11, but the other end side is a gently inclined surface. When the bone receiving support member 15 moves from the other end side to the one end side along the middle rod 11, the claw portion 35 a of the fully closed stopper 35 is pressed by the bone receiving support member 15 and is immersed in the middle rod 11. After the bone receiving support member 15 passes over the claw portion 35a, the claw portion 35a protrudes from the slit 36 to the outside of the intermediate rod 11, and the locked hole 16 of the bone receiving support member 15 is formed on one end side of the claw portion 35a. The main bone 17 is held in a fully closed state by locking.

<Suspension>
As shown in FIG. 1, at one end in the axial direction of the intermediate rod 11, a hanging tool 40 for suspending the umbrella portion 10 in a reverse umbrella shape is provided.

Can be greatly widened while being compacted during transportation and storage.
The fallen object collecting apparatus 1 is an apparatus that is used by suspending the umbrella part 10 in a reverse umbrella shape. The fallen object collecting sheet 21 receives the fallen object by one surface thereof, and also drops the fallen object from the opening 22 below. Drop into the collection container 50. Since the collection container 50 is detachable from the middle bar 11, the fallen matter collected in the collection container 50 can be easily discarded by removing the collection container 50 from the middle bar 11.

Moreover, since the some intermediate | middle stopper 33 was provided along the axial direction of the center stick | rod 11, the falling object collection sheet | seat 21 can be expanded to arbitrary sizes. The falling object collecting sheet 21 can be widened in a size suitable for the work space, and there are few restrictions on the place of use.
A cut line 25 was formed on the falling object collecting sheet 21 from the peripheral edge 21 a to the opening 22, and the cut line 25 was configured to be opened and closed by a fastener 26. Since the fastener 26 can open a part of the falling object collecting sheet 21, the falling object collecting apparatus 1 can be attached to a utility pole or the like.
Since the eyeball pattern is attached to the outer surface of the falling object collecting sheet 21, the eyeball pattern 27 is greatly expanded by opening the umbrella portion 10, and the harmful birds can be repelled.

[Second Embodiment]
The fallen object collection | recovery apparatus which concerns on 2nd embodiment of this invention is demonstrated. FIG. 6 is an elevational view showing a part of the fallen object recovery apparatus according to the second embodiment of the present invention in cross section. FIGS. 7A to 7C are cross-sectional views of the middle bar for explaining the operation of the intermediate stopper. Like the so-called jump umbrella, the fallen object recovery apparatus 2 according to the present embodiment is characterized in that the main bone 17 can be automatically opened. Hereinafter, differences from the first embodiment will be described, and the same members as those in the first embodiment will be denoted by the same reference numerals, and description thereof will be omitted.

<Basic configuration of the umbrella>
The umbrella part 10 of the fallen object recovery device 2 is disposed on one end side of the intermediate rod 11 with respect to the bone support member 15 and is attached to the intermediate rod 11 so as to be movable in the axial direction. One end 73a is swingably attached to an intermediate portion of each rib 19 and each other end 73b is swingably attached to the draw wire support member 71, and the bone receiving support member 15 and the draw wire support. An opening spring 75 (elastic urging member) is provided that elastically urges the member 71 away from each other.
The drawn wire support member 71 has a substantially cylindrical shape, and the middle rod 11 is inserted through the hollow portion thereof. The drawn wire support member 71 supports the drawn wires 73 arranged radially with respect to the middle rod 11. The opening spring 75 can be constituted by, for example, a compression coil spring through which the middle rod 11 can be inserted into the hollow portion.

The basic configuration of the fully closed stopper 35 according to this embodiment is the same as that of the first embodiment shown in FIG. 5C, and the fully closed stopper 35 is a leaf spring incorporated in the hollow inside of the intermediate rod 11. It is. In the present embodiment, the first point is that a fully-closed stopper operation button 35b for operating the nail part 35a of the fully-closed stopper 35 to be immersed in the middle rod 11 is provided closer to one end than the nail part 35a. Different from the embodiment.
Further, in the present embodiment, a locked hole (first locked hole 71 a) in which the claw portion 35 a of the full-closed stopper 35 is locked is formed not in the bone receiving support member 15 but in the drawn wire support member 71. This is also different from the first embodiment (see FIG. 7). The first locked hole 71 a is a long hole formed through the side surface of the intermediate portion in the axial direction of the drawn wire support member 71. When the claw portion 35a of the fully closed stopper 35 is locked in the first locked hole 71a, the bone receiving support member 15 and the draw wire support member 71 are brought close to each other against the elastic biasing force of the opening spring 75. The fully closed state is maintained.

<Basic operation of the umbrella>
The automatic opening operation of the umbrella unit 10 will be described.
The drawn wire 73 is in a posture along the axial direction of the middle bar 11 when in the closed state, and one end 73a attached to the intermediate portion of the rib 19 is separated from the middle bar 11 when in the opened state. For this reason, the bone receiving support member 15 and the drawn wire support member 71 are close to each other when in the closed state, and are separated from each other when in the open state.
An opening spring 75 such as a compression coil spring that elastically biases the bone receiving support member 15 and the wire drawing support member 71 in a direction to separate them from each other is disposed between the bone receiving support member 15 and the wire drawing support member 71. Yes. When the locking of the drawn wire support member 71 by the fully closed stopper 35 is released, the opening spring 75 separates the bone receiving support member 15 and the drawn wire support member 71 by its elastic biasing force, and both the support members are separated. In this state, the bone support member 15 is slid toward the other axial end of the intermediate rod 11 whose posture is stable.
In a state where the first locked hole 71a of the drawing wire support member 71 is locked to the claw portion 35a of the full-close stopper 35, the full-close stopper operation button 35b is pressed to bring the claw portion 35a into the middle rod 11. When immersed, the locking by the claw portion 35a is released. The bone receiving support member 15 is moved toward the other end in the axial direction of the intermediate rod 11 while being separated from the draw wire support member 71 by the elastic biasing force of the opening spring 75. Further, the drawn wire support member 71 moves to the other end side in the axial direction of the intermediate rod 11 together with the received bone 19 and the drawn wire 73 that move along with the movement of the received bone support member 15.

When the bone receiving support member 15 moves from the other end portion of the middle rod 11 toward the one end portion, the main bone 17 is expanded by the bone receiving portion 19 and the umbrella portion 10 is opened. The other end edge in the axial direction of the bone receiving support member 15 comes into contact with the main bone supporting member 13, and the bone receiving support member 15 stops in a state where the main bone 17 is fully opened.
On the contrary, when the bone receiving support member 15 is moved from one end of the middle rod 11 toward the other end against the elastic biasing force of the opening spring 75, the main bone 17 follows the middle rod 11 by the bone receiving 19. As a result, the umbrella portion 10 is closed. Further, the closed state is maintained by locking the first locked hole 71 a of the drawing support member 71 by the claw portion 35 a of the fully closed stopper 35.
In particular, in this embodiment, since the umbrella part 10 can be automatically opened, the umbrella part 10 can be opened even if there is a sudden attack of a pest, and the pest pattern 27 can immediately remove the pest.
