Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a door for a bird netting device.

[0002]

2. Description of the Related Art A bird-proofing net device is used to prevent birds from being harmed by birds entering through openings in buildings and the like, and the buildings are contaminated by excrement and missing feathers. It is a device for preventing intrusion. As a bird-proof net device, there is known a device that blocks birds from entering by opening a bird-proof wire around an opening of a building or the like at a smaller interval than the width of a bird's wing.

[0003]

In the above-mentioned conventional bird netting system, various birds and birds are wound around an opening of a building or the like, so that various maintenance devices are disposed in the opening. In such a case, it is necessary to temporarily remove the bird-proofing wire so that the worker can enter the opening during maintenance, and then re-wire the wire after maintenance, which is very troublesome. In addition, when a bird netting device is used for windows and doors, it is very difficult to quickly open and close, that is, remove the bird wire when emergency evacuation such as a fire occurs. At present, the layout of the windows and doors has been postponed, and birds are still afflicted by birds at openings with windows and doors.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an opening / closing door in a bird netting device which can be easily opened and closed.

[0005]

SUMMARY OF THE INVENTION The present invention provides a pair of fixed rails having a substantially C-shaped cross section which are attached to a stationary member so as to face each other, and a plurality of wires which are stretched on opposite edges of the fixed rail. A pair of slide rails provided with a plurality of guide rollers that rotate vertically in the longitudinal direction of both sides so as to engage with the fixed rail, and an edge on the opposite side of the slide rail A plurality of wires and a sliding door constituted by a plurality of wires, the sliding door engaging with the fixed net body is slidable along the longitudinal direction of the fixed net body. It is a door in a bird net device. Further, the present invention provides, in the above-mentioned opening and closing door in the bird netting device, a plurality of side rollers that rotate horizontally in the longitudinal direction of both sides of the slide rail of the slide door so as to engage with the fixed rail of the fixed net body. It is an opening / closing door in a bird netting device provided. Further, the present invention provides the above-mentioned opening and closing door of the bird netting device, wherein the wire stretched between the pair of fixed nets and the pair of sliding doors comprises a spring material and a wire. It is an opening / closing door in a network device.

13, 213 may be provided. The mounting support portion 213 is, for example, a plate protruding from the side surface of the fixed rail 21 as shown in FIG. 2, and a hole 214 is formed on the side surface, or a ring member (not shown) is provided. And so on. In the present embodiment, an example is described in which the bird wire 4 is used for the net portion of the fixed net body. However, a known wire may be provided. Details of the bird wire 4 will be described later.

<C> Sliding Door The sliding door 3 is slidably housed in the hollow portion of the pair of fixed net bodies 2 described above, and is a movable door such as an opening of a building in which the bird-proof wire 4 is stretched. And is composed of a slide rail 31 and a plurality of bird wires 4. On opposite side surfaces of the slide rails 31, mounting support portions 311 for hooking a bird wire 4 to be described later are provided. The mounting support 311 is, for example, a slide rail 3
1 is a plate protruding from the side surface, and a hole 31
2, or a ring material (not shown) may be provided. On both sides of the slide rail 31,
By disposing a plurality of guide rollers 32 in the longitudinal direction, the guide roller 32 can be engaged with and accommodated in the hollow portion of the fixed net body 2 and slide resistance generated by sliding on the inner surface of the fixed rail 21 of the fixed net body 2 when sliding. Can be reduced.

As shown in FIGS. 1 and 2, the guide rollers 32 are disposed on both sides of the slide rail 31 so as to contact the inner surface of the fixed rail 21 of the fixed net body 2 in the vertical direction. The direction of rotation is guided by a flange 212 formed on the peripheral edge of the opening 211. The arrangement of the guide roller 32 on the slide rail 31 is not limited to the example shown in FIG. 2 and various known arrangement methods and arrangement positions can be selected. Also, as the roller itself, a known roller such as one having a built-in bearing for receiving the rotation shaft can be used. Alternatively, a low friction material (not shown) may be provided instead of the guide roller 32.

<4> Bird Wire The bird wire 4 is a wire that is stretched between the pair of fixed nets 2 and 2 and between the pair of slide doors 3. The bird-proof wire 4 is stretched between the fixed nets 2 and 2 and between the sliding doors 3 and 3 by appropriately selecting intervals for preventing birds from entering. The bird-proof wire 4 includes a wire 41 for preventing birds from entering, and mounting clips 42 attached to both ends of the wire 41. It is conceivable that the wire 41 is made of a known material such as stainless steel and processed to produce a wire having a high tensile strength and a high rust-preventive force.

The attachment clip 42 is a member that is used for improving the attachment property and for applying a predetermined tension to the wire 41 when the wire 41 is stretched to a desired position. As the attachment clip 42, for example, as shown in FIG. 2, it is conceivable to constitute a spring portion 421 and a hook portion 422. The spring portion 421 of the mounting clip 42 is
Can be given a predetermined tension. Spring part 421
Can be easily attached by attaching a knot or a stopper member (not shown) larger than the opening to the end of the wire rod 41 at the end of the wire rod 41. In addition, the hook portion 422 has a structure that can be easily hooked on holes or rings formed in the mounting support portions 212 and 311 of the fixed net body 2 and the sliding door 3 in advance. Note that the above-described spring portion 42
The attachment clip 42 with 1 is an example of a clip attached to the wire 41, and it goes without saying that various other known clips can be used.

[0014]

The operation of the door in the bird netting device of the present invention will be described below.

<B> Installation Step of Opening and Closing Door in Bird Protecting Net Device Opening and closing door 1 (hereinafter referred to as open and close) in a bird protecting net device that can be opened and closed on windows and doors of a building or on openings having maintenance devices and the like Door 1). First, the opening / closing door 1 and a pair of fixed net bodies 2 and 2 serving as a base are arranged along the vicinity of the upper and lower edges of the opening by known means. The pair of fixed net bodies 2 and 2 are arranged so that the opening 211 and the mounting support portion 213 for hooking the bird wire 4 are opposed to each other. When attaching the fixed nets 2, 2, it is conceivable that the sliding door 3 is housed in the fixed net 2 in advance. As a result, the mounting support 311 of the bird-proof wire 4 of each of the sliding doors 3 and 3 is also opposed to each other.
