Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing structure of a crown used for connecting a roof of a cubicle and a roof.

[0002]

[Prior Art]

 Conventionally, the crown 10 has been attached to the roof 5 with bolts and nuts 8 as shown in FIG. 3 (a), and has been attached with screws 9 as shown in FIG. 3 (b).

[0003]

[Problems to be solved by the device]

 The one in Fig. 3 (a) requires a special tool because the space inside the roof is small and it is difficult to tighten the bolts while pressing the nuts with your fingers. In addition, the one shown in Fig. 2 (b) cannot be installed due to a slight deviation between the screw holes in the crown and the screw holes in the roof, and the roof can be aligned once it is installed. Absent.

[0004]

[Means for Solving the Problems]

 The present invention provides a structure capable of easily and surely attaching a crown in order to solve the above-mentioned conventional problems. That is, among the four side faces, a plate is formed in which the width of a pair of side faces facing each other is larger than the width of the gap and the width of another set of side faces is smaller than the width of the gap. A convex fixing tool having a locking projection for preventing slipping which can be fitted into the gap on the plate surface of the plate-shaped portion, and a bolt hole penetrating from the surface of the locking projection to the bottom surface of the plate-shaped portion; There is a combination with a bolt that can be screwed into the bolt hole through the bolt insertion hole of the crown.

Further, among the four side surfaces, a width of a pair of side surfaces facing each other is larger than a width of the gap, and a width of another pair of side surfaces is smaller than a width of the gap. A combination of a plate nut with a bolt hole, a bolt that can be screwed into the bolt hole through the bolt insertion hole of the crown, and a plate nut idling prevention member attached to the back surface of the eaves near the gap. Especially.

[0006]

[Action]

 In the convex fixture, one of the four side faces of the plate-shaped part has a pair of opposite side faces that is larger than the width of the gap formed between the roof bodies, and the other set of side faces has the width of the gap. Since it is smaller, the plate part can be inserted inside the eaves part so as to match the shape of the gap. Then, by rotating the convex fixing tool so that the side surface larger than the width of the gap is horizontal inside the roof body, the convex fixing tool is prevented from coming out of the eaves portion from the gap. Further, by fitting the locking protrusion for preventing idling into the gap from the inside of the eaves portion, idling when the bolt is screwed in is prevented. Therefore, the crown can be easily fixed to the eaves portion only by screwing the bolt into the bolt hole of the convex fixture via the bolt insertion hole of the crown.

Further, among the four side surfaces, a pair of side surfaces facing each other has a width larger than the width of the gap, and another pair of side surfaces has a width smaller than the width of the gap. By combining with a plate nut idling prevention member attached to the backside of the eaves near the gap, it is possible to screw in a bolt that prevents the plate nut from idling, and the crown can be easily attached.

【Example】

 1 and 2 are explanatory views showing a fixing structure (hereinafter referred to as a fixing structure) of a roof connecting crown of a cubicle according to the present invention. The present invention will be described below with reference to these drawings. Reference numeral 3 denotes a convex fixture, which is formed of a plate-shaped portion 31 and a locking protrusion 32 as shown in FIG. 2, and has a bolt hole 3a formed from the upper surface of the locking protrusion to the bottom surface of the plate-shaped portion. The plate-shaped portion has a pair of side surfaces 3b, 3b facing each other and another pair of side surfaces 3c, 3c, and the width L1 of the side surfaces 3b, 3b is formed between the roof body and the roof body shown in FIG. The width L2 of the side surfaces 3c, 3c is smaller than the width of the gap 5b. Further, the locking projection 32 is formed in a square pole shape so as to fit into the gap and prevent the convex fixture from idling.

Here, a case where a crown is fixed using a convex fixing tool and a bolt will be described with reference to FIG. First, the inner lid 6 and the outer lid 7 are placed on the lid mounting portions 5c, 5c formed in the front-back direction of the mating surfaces of the roof bodies 5, 5. Next, the bolt 1 is inserted through the bolt insertion hole 2a of the crown 2 and slightly screwed into the bolt hole 3a of the convex fixing tool 3, and the convex fixing tool is moved up and down with the side surfaces 3c, 3c as shown in the drawing. In this state, it is inserted into the gap 5b and rotated so that the side surfaces 3b and 3b are vertically arranged inside the eaves portion 5a, and in that state, the locking projection 32 is fitted into the gap 5b. Then, if the bolt 1 is screwed in in the fitted state, it is locked by the locking projection, so that the crown 2 can be easily fixed to the eaves 5a without idling the convex fixing tool. The roof bodies 5 and 5 are connected. Further, by loosening the convex fixture, either the left or right roof body can be vertically displaced, so that the roof bodies can be adjusted flush with each other. The shape of the locking projection is not limited to the square pole shape of the above embodiment, but may be a polygon such as a pentagon or a hexagon or an ellipse as long as it can prevent idling.

Next, a case where the crown is fixed using the plate nut and the plate nut idling prevention member will be described. Reference numeral 12 in FIG. 2 denotes a plate nut. The plate nut is formed in the same shape as the plate-like portion of the convex fixture, and the plate surface 12b is provided with a bolt hole 12a. Reference numeral 4 denotes an L-shaped stopper which is an example of a plate nut idling prevention member. First, as shown in FIG. 1, the stoppers 4 and 4 are respectively placed in the plate nut rotation preventing portions inside the eaves 5a and 5a so that the vertical interval between the stoppers is about the width of the side surface of the plate nut having a small width. Install. Next, insert the plate nut into the gap with the bolt 1 slightly screwed into the bolt hole of the plate nut through the bolt insertion hole 2a of the crown 2, and rotate so that the wide side surface becomes horizontal inside the eaves. Then, put it between the stoppers 4 and 4. Therefore, the bolt can be screwed in without idling the plate nut, and the crown can be easily attached. Figure 2 shows the fixed state.

The shape of the locking projection is not limited to the square pole shape of the above-mentioned embodiment, but may be a polygon such as a pentagon or a hexagon or an ellipse as long as it can prevent idling. Further, the number, shape, mounting position, etc. of the stoppers can be appropriately changed as long as they can prevent the idling of the plate nut.

[0012]

[Effect of the device]

 By using the fixing structure according to the present invention, the crown can be easily and quickly attached only by the bolt fastening tool without using a special tool even when the inner side of the roof eaves portion is narrow. Moreover, since the gap between the roof bodies is used, the mounting cannot be impossible due to the displacement of the mounting holes. Further, the roof bodies can be fitted to each other.
