In addition, as described above, the cylindrical body 20 and the support body 30 may be formed separately from each other first, and may be integrated by mechanical bonding or bonding, or may be integrally formed (integrated) by resin molding.

A pair of support portions 34 are formed protruding from both sides of the upper end of the support body 30. A support hole 34 a is formed in each support portion 34, and a support shaft 53 described later is attached to this portion. A pair of side walls 35 are formed on both sides of the support portion 34, and engagement portions 35 a are formed on the lower sides of the respective side walls 35.

The engaging portion 35a can be regarded as a recessed portion (including an opening hole), and constitutes an engaging means capable of elastic engagement with the cover body 50, and is provided in a state of elastic engagement (the cover body 50 is supported by the support body 30) In a fixed state), the function of the cover 50 is maintained. In addition, in each side wall 35, an inclined portion is formed in the engaging portion 35a. The guide surface 35b is used to guide a locking claw described later.

The support body 30 is rotatably supported by a cover 50 that opens and closes an opening 20A outside the cylindrical body 20. The main body 50A of the cover 50 may be integrally formed of, for example, a resin material, and includes a frame portion 51 having a slightly rectangular shape and a bulged portion 52 which is bulged into a dome shape. Notches 51b are formed on both sides of the upper sheet of the frame portion 51 to allow the pair of support portions 34 of the support body 30 to enter.

A support hole 51a is formed at the upper ends of both sides of the frame portion 51 so as to protrude from the support hole 34a formed in the support portion 34 of the support body 30. A support shaft 53 is allocated to this portion, and the cover body 50 pairs. The support body 30 is rotatably supported in the vertical direction. The support shaft 53 is provided so as to pass through the rotation spring 54. With the urging force of the rotation spring 54, the cover 50 is always pushed in the upward direction with the support shaft 53 as the center (the direction of the arrow in FIG. 8). ). That is, the rotation spring 54 includes abutment portions 54a formed at both ends of the spring portion, abutment portions 54b formed at the center of the spring portion, abutment portions 54a at both ends of the support body 30, and abutment at the center. The portion 54b abuts on a plate to be described later, and always pushes the cover 50 in a direction to be opened upward with the support shaft 53 as a center.

A pair of openings 52 a having a slightly trapezoidal shape are formed on the left and right sides of the bulged portion 52. An operation member (operation lever) 55 formed by, for example, resin molding is disposed in each of the openings 52a. Each operation member 55 is formed in a concave shape so that a finger can be inserted, and each operation member 55 is provided with a vertical wall 55a so that both operation members can be clamped with a finger (clamped with an index finger and a thumb). Further, circular openings are formed in the side portions of the operation member 55 facing each other. 55b, a compression spring 57 is assigned to this portion, and pushes each of the operation members 55 away from each other. Further, a pair of guide portions 52b are integrally formed on the upper and lower sides of the back surface of the bulging portion 52, and the plate-shaped portion 55d of the operation member 55 is positioned at this portion, and the operation member 55 is held to be movable only to the left and right. direction.

That is, by interposing a compression spring 57 between the circular openings 55b of the two operating members 55, the two operating members 55 can be pinched with fingers to resist the pushing force and move in directions close to each other, and when not pinched with fingers Is held in a state where they are pushed in directions away from each other by the urging force of the compression spring 57. In this way, the pair of operating members 55 are pushed into a direction away from each other by one compression spring, so that they are engaged. Even if it is assumed that one operating member is pushed into the releasing direction due to misoperation, the other Since the operation member of is not pressed into the state of the urging force of the compression spring and the engagement state is released, the cover can be reliably prevented from being opened due to an erroneous operation. In addition, by compressing a compression spring between the two members, the structure is simplified and the assembling work is easy.

Of course, a compression spring is provided in each operation member, and it can also be pushed in the direction away from each other.

Each of the operation members 55 is formed with a protruding claw 55 e that can be engaged with an engagement portion 35 a formed in the side wall 35 of the support body 30. The protruding claws 55e are guided and can be engaged with the inclined guide surface 35b against the pushing force in a state where the operating members 55 are pushed in directions away from each other by the urging force of the compression spring 57. The engaging portion 35a. That is, the protruding claw 55e of the operation member 55 and a support body that receives the protruding claw 55e The engaging portion (recessed portion) 35a of 30 constitutes an engaging means, and the two protruded claws 55e are urged in a direction to be engaged with the engaging portion 35a by the compression spring 57.

Therefore, if the lid body 50 is closed to the support body 30 against the urging force of the rotation spring 54, the protruding claw 55 e is engaged with the urging force (elastic force) generated by the compression spring 57. The engaging portion 35a. Moreover, by operating (pinch operation) the two operating members 55 against the urging force of the compression spring 57, the elastic engagement of the two can be easily released, and the cover 50 is still supported by the urging force of the rotation spring 54. The body 30 is rotationally driven.

In addition, as for the engagement means provided on the support body 30 and the operation member 55 described above, any of them may be a claw (protrusion), and the engagement relationship may be an engagement relationship between the claw and the recess, or may be This is a relationship in which the convex portions can be locked to each other. For example, as shown in FIG. 10, a convex portion 35f may be formed on the side wall 35 of the support body 30 first, and the above-mentioned protruding claw 55e may be engaged with this portion.

A plurality of screw holes 60 are formed in the cover 50 in which the operation member 55 is assembled. These screw holes 60 protrude from the back side of the bulged portion 52 in a direction orthogonal to the side wall 3A. In this embodiment, four places are formed at four corners of the cover 50. In this cover 50, a plate-shaped plate 65 is mounted by screwing a screw (not shown) into the screw hole 60, and the inside of the frame portion 51 is blocked by the mounting plate 65, so that the pair of operation members 55 are blocked. Be prevented from falling off.

This situation is formed on the plate 65, left and right, respectively. The notch 65a in the shape of a shape exposes the protruding claws 55e of the two operation members 55 blocked by the plate 65. When the plate 65 is attached to the cover 50, the rotation spring 54 is exposed, and the central contact portion 54b abuts the upper end edge 65b of the plate 65.

A round protrusion 65c is integrally formed on the exposed surface when the aforementioned plate 65 is mounted so as to fit the opening 20A of the cylinder 20, and a rubber or silicone cover is first placed on the round protrusion 65c. The body 66 is preferable, so that when the cover 50 is closed, the tightness is ensured between the cover 20 and the opening 20A of the cylinder 20, and the cover 66 and the opening 20A are tightly sealed to prevent water leakage.

Next, the function of the drainage portion 10 mounted on the side wall 3A of the main body 3 as described above will be described.

In the normal state of the cool box, the cover 50 is engaged with the support 30 against the urging force of the rotation spring 54 (see FIG. 7 (a) and FIGS. 8 and 9). At this time, the cover body 66 of the plate 65 attached to the main body 50A of the cover body 50 is tightly fitted to the opening 20A of the cylindrical body 20, and the internal water does not leak to the outside (the cover body is blocked). Furthermore, in this state, since a pair of protruding claws 55e formed on the operating member 55 of the cover body 50 are elastically engaged with the engaging portions (concave portions) 35a of the support body 30, rotation of the cover body 50 is prevented. Does not open the drain.

When draining water, the vertical walls 55a of the pair of operation members 55 are clamped with fingers (clamped with forefinger and thumb). At this time, each operation member 55 moves in a direction approaching each other against the urging force of the compression spring 57, and the protruding claw 55 e of each operation member 55 comes off from the engaging portion (concave portion) 35 a of the support body 30. Accordingly, the engagement relationship between the cover 50 and the support 30 is released, and the cover 50 is rotated by the arrow of FIG. 8 by the urging force of the rotation spring 54. In the head direction, as shown in FIG. 7 (b), the cover 50 is opened (the opening 20A of the cylinder 20 is released). In this state, the water in the main body 3 can be allowed to flow out to the outside through the cylindrical body 20.

In addition, in this embodiment, the two ends 51c of the frame portion 51 of the cover body 50 are brought into contact with the upper end section 35d formed on the side wall 35 of the support body 30, so that the rotation of the cover body 50 is restricted, and the cover body 50 The support 30 (side wall 3A) is restricted from rotating at a position of slightly 90 °

As described above, when draining, the cover 50 does not use the fingers to lift up, and can be rotated in the up-down direction only by the urging force of the rotation spring 54 and fixed at a slightly horizontal position. In some cases, the cover 50 will automatically retreat from the outflow path to prevent the outflowing water from contacting the cover 50, and the internal water can be discharged hygienically. In addition, since the support body 30 and the cover body 50 are engaged with each other by means of elastically engageable means, the cover member 50 is provided with an operation member 55 that releases the elastic engagement by the engagement means. The operation member 55 is operated (a simple operation of pinching only a pair of operation members 55 in this embodiment), and the opening 20A of the cylinder 20 is opened by releasing the elastic engagement.

In addition, in the above-mentioned configuration, the support body 30 and the cover body 50 can be positioned with reference to the support shaft 53 supported by the support portion 34 formed on the support body, so that the protruding claws of the engagement means can be made with high accuracy. 55e is engaged with the engaging part (recessed part) 35a. That is, compared with a configuration in which one of the engaging means is disposed on the side of the body 3 on which the drainage unit is installed, the mounting accuracy is improved, so the engagement accuracy of the two is improved, and a stable opening and closing state of the cover 50 can be ensured. When the cover 50 is blocked, the cover is made to resist the urging force of the rotation spring 54 only. The body 50 is turned toward the support body 30, and the simple operation of pressing the support body 30 can keep the engaging means in the engaged state, and the plugging operation can be easily performed.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made.

Although the operation member 55 is configured by pinching each other in the form of a pair of levers in the above-mentioned embodiment, it may be configured by a single lever that engages the support body 30 by the above-mentioned engaging means. For example, as shown in FIGS. 11 and 12, the operation member 55 may be disposed only on one side of the bulged portion 52 of the cover 50. In this configuration, a holding wall 91 having a holding portion 90 is provided on the back surface of the main body 50A of the cover body. The holding portion 90 accommodates the base end side of the compression spring 57 while abutting and holding the base end portion, and performs a single operation. The member 55 is urged in the direction of the arrow D in FIG. 12, and the engaging means (the protruding claw 55 e and the recessed portion 35 a) are engaged by the urging force. In this configuration, the operation and structure of opening the cover can also be simplified. In addition, the cover 50 is not provided with the retaining wall as described above, and the compression spring 57 may be abutted against the frame portion 51 as it is, or the abutment portion may be partially formed first, and the compression spring 57 may be abutted here.

Further, as shown in FIGS. 13 and 14, a configuration may be adopted in which the operating member 55A can be moved in the up-down direction and pressed tightly so that the engaging means (not shown) is engaged in the downward direction. force. In this configuration, a finger is brought into contact with the operation wall 55b of the operation member 55A, and the operation member 55A is lifted (pull-up operation) in the direction of arrow D1 to resist the pushing force to release the engagement of the engagement means. . In this way, the operation direction of the operation member can be appropriately deformed. In addition, it can also be as follows Composition: The push-button operation member is pushed in, or the convex member is slid to release the engagement state of the engagement means. Furthermore, the shape of the cover is not particularly limited to a circular shape.
