Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connecting tool for connecting protective screens such as a protective net and a protective sheet to each other.

[0002]

[Prior art]

 Generally, at a construction site, a scaffolding frame is assembled, and a protective curtain is stretched outside the scaffolding frame to prevent falling objects from scattering around the site and improve safety.

Here, since the protective curtain has a predetermined size, it is necessary to connect the protective curtains to each other when the protective curtain is stretched.

In connection with the protection curtain, conventionally, as shown in FIG. 4, a plurality of eyelet fittings 12 are attached to an outer peripheral portion of the protection curtain 11, and a string 13 is inserted into the eyelet fittings 12 to protect the curtain 1. 1 is connected to each other.

[0005]

[Problems to be solved by the device]

 By the way, the connection of the protective screen 11 using the string 13 has a problem that the connection is very troublesome because the string 13 must be sequentially inserted into each of the eyelet fittings 12 arranged in one direction.

An object of the present invention is to solve the above-mentioned problems and to provide a connecting tool capable of connecting protective curtains very easily and surely.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, an engaging shaft portion is provided along each side edge of a pair of flanges provided on both sides of a plate body, and a pair of engaging members provided inside each flange. One side part of the plywood is rotatably attached to the connecting plate, and the other side part of each engaging plate is provided with a bent portion having elasticity capable of engaging with the outer periphery of the engaging shaft part. .

[0008]

[Action]

 When connecting the protective curtain, insert the opposing ends of the pair of protective curtains to be connected between the engaging shaft and the bent portion of the engaging plate at the disengaged position, and then connect the pair of engaging plates. The bent portion is engaged with the engaging shaft portion so that the bent portion and the engaging shaft portion sandwich the end portion of each protective curtain.

[0009]

【Example】

 An embodiment of this invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, the frame body 1 has a U-shape in which a pair of flanges 3 a and 3 b are provided on both sides of a rectangular plate body 2, and side edges of the flanges 3 a and 3 b are formed. An engaging shaft portion 4 is provided along the. Further, on the inner surface of the plate body 2, there is provided a pair of cylindrical portions 5 extending long in both end directions of the plate body 2. The tubular portion 5 has a detaching portion 6 extending in the axial direction, and the detaching portion 6 faces the engaging shaft portion 4.

The engagement plate 7 provided inside each of the flanges 3 a and 3 b of the frame body 1 has a circular shaft portion 8 on one side, and the shaft portion 8 is inserted into the cylindrical portion 5 to rotate. It is supported freely.

An elastically deformable bending portion 9 is provided on the other side portion of the engaging plate 7. The bent portion 9 is engageable with the engaging shaft portion 4 provided on the flanges 3a and 3b.

In the embodiment, the engaging shaft portion 4 has a circular cross-sectional shape and the bent portion 9 has an arc shape capable of enclosing a half circle or more of the engaging shaft portion 4. The cross-sectional shapes of 4 and the bent portion 9 are not limited to this. For example, the engaging shaft portion 4 may be a triangle or a trapezoid whose hypotenuses are arranged vertically. The bent portion 9 is shaped so as to enclose the engaging shaft portion 4.

Now, as shown by the chain line in FIG. 2, with the bent portion 9 of the engaging plate 7 in the disengaged state, the protective curtain A is provided between the bent portion 9 and the engaging shaft portion 4. By inserting the end portion, swinging the engaging plate 7 toward the engaging shaft portion 4, and engaging the bending portion 9 with the engaging shaft portion 4, the bending portion 9 and the engaging shaft portion 4 are protected. The end of the curtain A can be clamped, and the protection curtain A can be connected.

As shown in FIG. 1, by forming the hole 10 in the plate body 2 of the frame body 1, the frame body 1 can be connected to the scaffold frame by a string or the like inserted into the hole 10. Therefore, it is possible to stabilize the attachment of the protective curtain A that is stretched around the scaffold frame.

[0016]

[Effect of device]

 As described above, in the connector according to the present invention, after the end of the protective curtain is inserted between the engaging shaft portion provided on the side edge of the flange and the bent portion of the engaging plate, the engaging plate is engaged with the engaging shaft portion. By swinging toward the front and engaging the bent portion with the engaging shaft portion, the end portions of the protective curtain can be sandwiched between the engaging shaft portion and the bent portion. Can be connected.

Further, since the end portion of the protective curtain is sandwiched between the engaging shaft portion and the bent portion, the protective curtain can be firmly connected to each other.
