Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a U-shaped gutter with an opening / closing lid, which is used for sewage.

[0002]

[Prior art]

 Conventionally, in order to remove the closed gutter, in order to remove the closed lid, an instrument such as a burl was used to remove it, and this was placed near the gutter to carry out the cleaning work.

However, it is extremely difficult to remove the lid from the gutter, and if the lid is removed and there is a moat or the like on one side of the gutter, the removed lid is left on the road, which will obstruct traffic and again. The lid was heavy and difficult to install, and there was a risk of injury.

In order to solve the above-mentioned drawbacks, a U-shaped groove opening / closing device as disclosed in Japanese Utility Model Publication No. 2-135292 has been proposed. That is, as shown in FIG. 5, a plurality of holding holes 2 of the locking metal fittings C are formed at a required angle at one corner position of the lid receiver 1 of the U-shaped groove main body A, and the locking metal fittings C are covered. One end of the locking punch C1 placed on the bridge 1 is bent at an angle to be fitted into the holding hole 2 to form a support punch C2, and the other end is located above the locking punch C1 and the direction of the support punch C2. The supporting punch C2 of the locking punch C1 is fitted and held in the holding hole 2, and the notches 3 are provided on both sides of the lid B. An escape hole 4 for the locking piece C3 is provided on the back surface of the lid B.

[0005]

[Problems to be solved by the device]

 However, the conventional U-shaped groove lid opening / closing device has the following drawbacks. (1) When the lid B is opened, the lower end of the lid B moves in contact with the lid receiver 1 and the locking punch C1 of the U-shaped groove body A, so that the opening is not smooth and there is force.

(2) When closing the lid B, the lid B cannot be inserted into the lid receiver 1 unless the lid is once lifted up and displaced by using the notch 3 for a handle with both hands.

The present invention has been made in view of the above-mentioned circumstances, and an L-shaped roller receiving member is provided on the upper end of the inner wall on one side of the gutter body, and the roller connecting member is attached to one end face in the width direction of the lid. A roller that is arranged and pivotally attached to the roller hardware is configured to be operated with one hand by rotating the roller hardware on the surface of the lid and one side of the roller hardware connected to the lid. It is intended to provide a gutter with a lid.

[0008]

[Means for Solving the Problems]

 The present invention comprises a gutter main body, a lid, and an opening / closing hardware, wherein the opening / closing hardware is attached to an upper end of one inner side wall of the gutter main body at a predetermined interval and is L-shaped. The side of the roller receiver extends horizontally from the surface of the lid of the gutter body as the same continuous surface, and the tip is bent upward, and a stopper is fixed on that side, and the width of the lid. One end face in the same direction is embedded at the same interval as the roller receiving object, the roller is pivotally attached in a state where a part of the outer periphery is seen from one corner of the end face, and the other end is locked by the stopper. A roller metal member having an abutting portion formed therein, and a recessed portion for forming a bent end of the roller metal receiver is formed on the back surface of the lid in a state where the lid body is closed by the gutter body. A handhold is provided near at least the other end face in the width direction. When the lid is opened 90 degrees or more, the contact portion is locked to the stopper and the top surface of the lid comes into contact with the upper edge of the standing wall of the lid receiver to stop. When the lid is opened and closed, the roller is It is characterized in that it rolls on the lid receiving surface and on one side of the roller receiving object.

[0009]

[Action]

 When the lid is rotated more than 90 degrees and opened, the abutting portion of the roller metal object is locked by the stopper, so that the lid is stopped by the stopper and the upper edge of the upright wall of the lid receiver so as not to move.

Further, when the lid is opened and closed, the roller of the roller metal object rolls on the lid receiving surface of the gutter body and the upper surface of the roller metal object extending from the lid receiving surface.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the present invention comprises a gutter main body 10, a lid 20, and an opening / closing metal fitting, and the opening / closing metal fitting is provided on the upper end of one side inner side wall 11 of the gutter main body 10 at a predetermined interval with a concrete interval. It is composed of a pair of roller brackets 30 bolted with bolts 31, and a roller bracket 40 embedded in concrete at the same interval as the roller bracket 30 on one end face 21 in the width direction of the lid 20.

The roller 41 is pivotally attached to the roller hardware 40 in a state where a part of the outer periphery of the roller 41 is seen from one corner 44 (FIG. 3). The other corner 45 is formed with a contact portion 42 bent in a V shape, and as shown in FIG. 2 (b), the contact portion 42 is opened when the lid 20 is opened 90 degrees or more. The tip is locked to a rod-shaped stopper 32 of the roller receiving object 30. In this state, the surface of the lid 20 comes into contact with the upper edge 13a of the standing wall 13 of the lid receiver 12, so that the lid 20 stops and stabilizes while being slightly tilted from the vertical.

As shown in FIG. 3, the roller 41 of the roller hardware 40 is pivotally attached to a pair of brackets 43 standing upright from the bottom of the roller hardware 40, and a part of the outer periphery 41 a of the roller 41 is one of the roller hardware 40. A part is looking from the corner 44. FIG. 3B shows a cross section taken along the line AA of FIG. As shown in FIG. 4, the roller receiving object 30 is formed in an L shape in which the tip of one side 33 is bent upward, and a round bar stopper 32 is provided on one side of the upper surface of the one side 33. Is welded. The roller receiving object 30 is bolted to the upper end of the inner wall 11 on one side with a concrete bolt 31, and the upper surface of the one side 33 extends horizontally from the surface of the lid receiver 12 as the same continuous surface. FIG. 4B shows a cross section taken along the line BB of FIG.

A U-shaped handle 23 is provided near the end surface 22 of the lid 20 opposite to the roller hardware 40 (FIGS. 1 and 2). A recess 24 is formed on the back surface of the lid 20 in which the bent end 33a of the roller metal article is accommodated when the lid 20 is closed as shown. Instead of the hand-held member 23, an end surface 22 on the opposite side of the roller-shaped metal member 40 may be provided with a sulcus that allows the hand to be inserted.

To open the lid 20, pull out the clasp 23 in the state of FIG. 2 (a), and pull up the lid 20, so that the roller 41 rolls on the roller receiving article 30 via the lid receiving 12 surface. Therefore, the lid 20 can be easily opened to the position shown in FIG. To close the lid 20, when the lid 20 is brought down by holding the clasp 23, the roller 41 comes into contact with the inside of the bent end 33a of the roller receiving object 30, and passes through the upper surface of the roller receiving object 30 and the surface of the lid receiving member 30. Rolling up, the state shown in FIG. 2B is changed to the state shown in FIG. 2A, and the lid 20 is closed.

[0016]

[Effect of device]

 According to the present invention described in detail above, the following effects can be obtained. Since the lid has rollers, in the conventional case, it was necessary to lift the lid with both hands when closing the lid. This makes it possible to open and close the lid easily.
