DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger for a ceiling channel. More specifically, the present invention relates to a ceiling base channel hanging fitting for attaching a long channel for ceiling base in an inclined state to a hanging member such as a hanging bolt hung from above.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 8, as a hanging metal fitting for an inclined channel as described above, as shown in FIG. It is known that a hanger 104 is connected at its upper end by a pin 106 so as to be rotatable around a horizontal axis.

However, when the channel 3 is locked to the hanger 104 in the hanging fitting 100, a torque T is generated around the pin 106 by the vertical load F acting on the hanger 104 from the field support 3. This torque T forcibly tilts the ridge 3 in a clockwise direction, making it difficult to perform the construction and causing a problem in that the position of the ceiling surface supported by the ridge is inconsistent.

Further, since the hanger 104 is rotatable around the pin 106, the inclination posture of the field edge holder 3 locked to the hanger 104 is not stable, and it is difficult to perform the construction. 3, there is a problem in strength that the vertical load F acting on the hanger 104 is concentrated and the hanging bracket 100 is easily damaged by shearing of the pin 106.

[0005]

In view of such a problem,
A first object of the present invention is to provide a hanging metal fitting for a channel for ceiling base, which is difficult to forcibly incline and easy to construct.

A second object of the present invention is to provide a hanging metal fitting for a channel for a ceiling base, which can maintain the inclined posture of the channel and has high strength.

[0007]

In order to achieve the above object, a first feature of the present invention is that a long channel for a ceiling base is attached to a suspension member suspended from above in an inclined state. In the configuration, the channel is sandwiched between a pair of holding pieces connected at the bottom, and a fitting body provided with a connecting portion for the hanging member on one of upper portions of the holding pieces, and is engaged with a flange of the channel. A positioning member having a pair of slits and a channel sandwiched between the pair of holding pieces, and a tightening body that penetrates the positioning body and tightens the pair of holding pieces so as to approach each other, The positioning body is configured to be vertically movable with respect to the metal fitting body and to be angularly displaceable around the fastening body.

In a second aspect of the present invention, in addition to the first aspect, the tightening member is a screw penetrating an upper portion of the holding piece. Is formed so as to be vertically movable with respect to the metal fitting body and to be angularly displaceable around the tightening body.

In a third aspect of the present invention, in addition to the first or second aspect, a pair of female screw portions capable of screwing a screw in a vertical direction is provided with the holding piece. The bracket is formed on the bottom of the bracket main body so as to be separated from the left and right sides as viewed in a direction orthogonal to.

On the other hand, a fourth characteristic configuration of the present invention is a configuration for attaching a long channel for a ceiling base in an inclined state to a suspending member suspended from above.
Providing a first member provided with a connecting portion to the hanging member, and a second member provided with a connecting portion to the channel, the first and second members are relatively rotated around a horizontally oriented rotation axis. The rotation shaft is disposed at the center of the second member in the width direction of the channel.

According to a fifth aspect of the present invention, in addition to the fourth aspect, the second member is formed in a substantially U-shape in a side view having a pair of holding pieces. The opening is oriented in the direction of the rotation axis, and a tightening screw for tightening the pair of holding pieces so as to approach each other is provided between the pair of holding pieces.

[0012]

According to the first feature, the positioning member is configured to be vertically movable with respect to the metal fitting body and to be angularly displaceable around the tightening member. It is possible to appropriately adjust the inclination posture of this channel in a state where the flanges are engaged. Since the flange of the channel is engaged with the pair of slits provided in the positioning body, the channel is restricted from being angularly displaced relative to the positioning body and moving in the width direction of the channel. Then, when the tightening member is tightened with the channel inclined in an appropriate posture, the channel and the positioning member are sandwiched between the pair of holding pieces, and the positioning member with respect to the vertical direction of the positioning member with respect to the bracket main body. The movement and the angular displacement with respect to the periphery of the tightening body can be restricted. Therefore, the channels engaging with the slits of the positioning body are restricted from being angularly displaced with respect to the metal fitting body and from moving vertically. Here, since the metal fitting itself is not inclined, the torque generated by the above-mentioned conventional hanging metal does not occur. If the channel is clamped only by the bracket body without the positioning body, the channel may move up inside the bracket body due to the tilting posture of the channel. As a result, it may slip down in the bracket main body and cause a dimensional error, and is not suitable as a hanging bracket. However, such a disadvantage does not occur in the present invention in which the variation of the inclination posture of the channel is restricted.

Further, according to the second characteristic configuration, since the positioning member has the long hole, it is not necessary to form the long hole on both of the pair of holding pieces while aligning the long hole. Is easy.

According to the third feature, the lower portion of the channel can be supported by both the left and right corners of the bottom and the tip of a screw screwed into the other female screw portion. Support from below is ensured. Further, a screw can be further brought into contact with the channel in a state where the variation of the inclination posture is restricted, from the lower side, and the change of the inclination posture of the channel can be more firmly restricted.

On the other hand, the vertical load due to the channel acts on the center of the channel in the width direction. According to the fourth feature, the rotating shaft is arranged at the center of the second member in the width direction of the channel. Therefore, no torque is generated around the rotation axis due to the vertical load due to the channel.

Further, according to the fifth characteristic configuration, since the openings of both the holding pieces are oriented in the rotation axis direction, the channel can be connected to the second member from the lateral direction. Further, since the tightening screw is provided between the pair of holding pieces, the tightening operation of the tightening screw can be performed from the lower side, and the workability is good.

[0017]

As described above, according to the first and fourth aspects of the present invention, it is difficult to forcibly incline the channel without generating torque as in the prior art, and the ceiling can be easily installed. It has become possible to provide a hanging metal fitting for a base channel.

Further, according to the first characteristic configuration of the present invention, it is possible to provide a hanging metal fitting for a channel for a ceiling base, which can maintain the inclined posture of the channel and does not concentrate the load locally, and has high strength. .

Further, according to the second characteristic configuration, the manufacture of the hanging fitting is facilitated, and according to the third characteristic configuration, the inclined posture of the channel can be more firmly maintained. According to the characteristic configuration, the mounting of the channel has become easier.

[0020]

Then, in a state where the lower flange 3b of the field support 3 is in contact with one of the left and right corners of the bottom portion 16, the attitude of the field support 3 is adjusted to a desired angle. The positioning body 20 includes a tightening screw 30.
Since it can be angularly displaced around and can be moved up and down by the elongated hole 24, the position and the attitude of the positioning member 20 are determined by adjusting the field edge support 3 in accordance with this.

When the tightening screw 30 is tightened in a state where the vertical position, the angle, and the like of the field support 3 are fixed, as shown in FIG. 4, the field support 3 and the positioning member 20 are By being clamped between the holding pieces 15, the change in their posture is regulated. Further, the positioning body 20 is sandwiched between one of the sandwiching pieces 14 and the flange 3a on the upper side of the field margin receiver 3, and also sandwiched between both the sandwiching pieces 14 and 15. With these pinchings, the movement of the positioning body 20 with respect to the metal fitting body 10 in the vertical direction or the longitudinal direction of the long hole 24 and the angular displacement with respect to the periphery of the tightening screw 30 can be restricted.
The variation of the inclination posture of the field receiver fitted to the positioning body 20 is regulated.

The tip of the tilt holding screw 32 is brought into contact with the lower flange 3b of the ridge 3 so that
It is possible to support the ridge 3 from the lower part thereof while maintaining the inclined posture. Moreover, when the tilt holding screw 32 is tightened in a state where the position of the field support 3 is fixed by the positioning body 20, the field support 3 is pressed between the positioning body 20 and the tilt holding screw 32. In addition, the mounting posture of the field margin support 3 in the inclined state with respect to the hanging bracket 5 is less likely to fluctuate.

Next, a second embodiment of the present invention will be described with reference to FIGS. The hanging member 7 in the present embodiment includes a first member 50 having a connecting portion 52 for the hanging bolt 2 and a second member 60 having a connecting portion for the ridge 3.

The first member 50 includes a plate-shaped horizontal bolt connecting portion 52 having a through hole through which the suspension bolt 2 passes, and a shaft mounting plate 54 orthogonal to the bolt connecting portion 52. .

The second member 60 is formed in a substantially U-shape in side view, having a pair of holding pieces 62 and 64 at the upper and lower ends of a bottom 63, and a through hole 6 formed in one holding piece 62.
The fastening screw 34 is made to penetrate through 2a, and its tip is screwed into a screw hole 64a formed in the other holding piece 64, so that the pair of holding pieces 6 are tightened by the tightening screw.
It is configured so that the two and 64 can be tightened so as to be close to each other.

The first and second members 50 and 60 are
Are connected so as to be relatively rotatable around a horizontally oriented rotation axis H. The pin 70 has an enormous head 72, and is penetrated in the horizontal direction from the bottom of the second member 60 toward the shaft mounting plate 54, and is also passed through the washer 74 on the shaft mounting plate 54 side. The pin 70 is prevented from coming off by crushing the tip. The center of the bottom is depressed so that the pin head 72 does not project from the bottom 63,
