Description

TECHNICAL FIELD The present invention relates to a structure for opening and closing a post used as a mail receiver or a newspaper receiver in a general household.

2. Description of the Related Art Conventionally, in a post used in a general household, an opening for inserting a postal matter into the post and a takeout for taking out the postal matter into the post An opening is provided, and a hinge-type lid or a slide-type lid is provided in both openings.

In the post provided with the slide type lid, the lid is slidably supported in the vertical direction, and when the lid is slid upward, the opening is opened, and the lid is opened. The opening is closed when the body is slid downward.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, in the case where the slide-type lid body of the post is configured to be opened by sliding it upward, in this open state, the post is opened. In order to take out the postal matter from inside the main body, one hand must support the lid in an open state, and the other hand must take out the postal matter, which complicates the taking-out work. .

Of course, if the lid body is locked to the post body when the lid body is operated to the open position, the mail can be taken out easily, but it is simply locked to the lid body and the post body. Therefore, the smoothness at the time of opening the lid is impaired due to the resistance at the time of locking, and the smoothness at the time of closing the lid is impaired by the resistance at the time of unlocking. It was

The present invention has been made in view of such conventional problems, and provides an opening / closing portion structure for a post that enables the lid body to be locked in the open position while ensuring smooth opening / closing operability. That is the purpose.

Means for Solving the Problems In order to solve the above problems, according to the present invention, an opening is formed in a vertical wall provided in a post body made of a box body, and the vertical wall of the vertical wall is provided in the post body. A post that supports a lid body that slides vertically along the back surface and is movable between an open position that releases the opening and a closed position that closes the opening, and is fixed to the back surface of the vertical wall. While providing the locking portion, the lid body is provided with a front surface portion along the back surface of the vertical wall and corner portions having a curved cross-section integrally formed on both sides of the front surface portion, and the lid body is provided on the front surface portion. There is provided a movable-side locking portion that engages with the fixed locking portion when it reaches the open position.

The fixed-side locking portion is a first ridge that is provided on the back surface of the vertical wall and extends in the horizontal direction, and the movable-side locking portion is provided on the lid body. It is a second ridge that passes over the first ridge and reaches the upper portion thereof when reaching the open position, and the surface that comes into contact with the first ridge and the second contact is curved.

In addition, while forming a vertically extending guide protrusion on the side wall of the post body, both side edges of the lid are slidably contacted with the guide protrusion, and both sides of another vertical wall facing the vertical wall are formed. An extending portion is provided on the inside of the side wall, and the guide convex portion is formed by a step between the side wall and the extending portion.

Further, a convex portion that extends in the up-down direction in the lid body and has a lower end portion that forms an open slit, and that the slit fits into the post body as the lid body reaches the closed position. Is provided.

Action In the above structure, when the lid body is slid when the postal matter or the like put into the post body is taken out, the lid body reaches the open position and the fixed side locking provided on the post body side The movable side locking portion provided on the lid side is engaged with the portion, whereby the lid is locked at the open position. Therefore, even if the lid is not maintained in the open position by the fingers, the opening is maintained in the open state, and the mail in the post body can be taken out from the opening maintained in the open state. At this time, since the lid body is provided with the front surface portion and the curved corner portion, when the locking portions are engaged, the corner portion of the lid body is appropriately elastically deformed, As a result, the resistance at the time of engagement of both locking portions is reduced.

Similarly, when the lid locked at the open position is slid to the closed position, the corner portion having a curved cross section is appropriately elastically deformed, so that the resistance at the time of disengagement is reduced.

Further, if the movable side locking portion and the fixed side locking portion are the first ridge and the second ridge, when the second ridge crosses over the first ridge, The lid body is elastically deformed and can be passed over with a small amount of resistance, and particularly when the contact surface of each of the ridges is curved, the resistance at the time of further riding is reduced. Therefore, this makes it possible to minimize the resistance when operating the lid body to the open position or the closed position, and after the second ridge has crossed over the first ridge, the second ridge is pushed. The lid is maintained in the open position by being in the engaged state in which the strip is located above the first protrusion.

Also, if both sides of the lid are slidably contacted with the guide protrusions provided on the post body, the lid is supported on both sides and sufficient elastic deformation is achieved in the general portion between the both sides. The amount is obtained.

Further, the guide protrusion is formed by a simple structure in which the guide protrusion is formed by a step between an extension portion provided on the other vertical wall and a side wall.

Further, when the lid body reaches the closed position, the slit provided in the lid body fits with the fitting convex portion, thereby preventing rattling of the lid body in the closed position.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIGS. 1 to 4, the post body 1 includes a front wall 2, which is a vertical wall, left and right side walls 3, 3, a rear wall 4 which is a vertical wall facing the front wall, a bottom wall 5, and A box having a roof 6, a rectangular opening 7 is provided in a lower portion of the front wall 2, and the roof 6 is supported by an upper end of the rear wall 4 so as to be openable and closable. There is.

The front wall 2 and the side walls 3 and 3 are integrally formed with each other through curved shapes 8 and 8 as shown in FIG. The rear surface 2a of the front wall 2 is provided with a first ridge 9 extending horizontally in the upper portion thereof, and the first ridge 9 will be described later as shown in FIG. A lower surface that is a contact surface with the second protrusion is formed in a curved shape. Also, the both side walls 3,3
Fitting protrusions 10 and 10 (only one of which is shown) are provided on the lower surfaces of the rear surfaces 3a and 3a so as to extend in the vertical direction.

On both sides of the rear wall 4, there are provided extending portions 11, 11 extending so as to be orthogonal to the general portion 4a of the rear wall,
The extended portions 11, 11 are joined to the back surfaces 3a, 3a of the left and right side walls 3, 3. Thereby, the back surface 3a, 3a and the extension portion 1
A guide protrusion 12 is formed which is a step between the guide protrusion 12 and the protrusions 11, 11. The guide protrusion 12 extends in the vertical direction.

On the other hand, a lid 13 is provided on the rear surface 2a side of the front wall 2, and the lid 13 has the front wall 2 as shown in FIG.
Along the curved portion 8 provided on both sides of the front surface portion 14 and along the curved portion 8, and extending through the corner portions 15 and 15, Side portions 16 and 16 having a shape along the side walls 3 and 3 are integrally formed.

The lid 13 has a closed position for closing the take-out opening 7 shown in FIG. 1 (a) (b), and FIG. 2 (a) (b).
Is slidable to the open position for fully opening the opening 7 shown in FIG. 2, and the front surface portion 14 passes over the first ridge 9 in the closed position and reaches the upper portion thereof. A second protrusion 17 is provided which is brought into an engaged state by being engaged. As shown in FIG. 8, the second ridge 17 has a curved upper surface which is a surface in contact with the first ridge 9, and the lower end portions of the side surface portions 16 and 16 are formed. A slit 18 is provided in the. The slit 18 extends in the up-down direction and has a lower end portion which is open. When the lid 13 is slid to the closed position shown in FIG. It is provided at a position where it can be fitted onto the portion 10.

The side edges 16, 19 of the side portions 16, 16 are formed on the guide protrusions.
It is in sliding contact with 12.

In this embodiment having the above-described structure, the post 6 is put into the post body 1 with the roof 6 open, as shown by the arrow in FIG. Then, when the inserted postal matter is taken out, the lid 13 is slid upward as shown by an arrow in the figure. Then, the second ridge 17 is attached to the first ridge.
After getting over the ridge 9, the first ridge 17 is brought into contact with the upper portion of the first ridge 17 to be in a locked state. As a result, the lid 13 is held in the open position, and even if the lid 13 is not maintained in the open position by fingers,
The opening 7 is maintained in the open state, and the postal matter in the post body 1 can be taken out from the opening 7 maintained in the open state.

At this time, since the lid 13 has the curved corner portions 15 and 15, the second ridge 17 is formed by the first ridge 9.
When you get over the corner, the corner parts 15,15 elastically deform appropriately,
The second ridge 17 can easily get over the first ridge. Accordingly, by moving the lid body 13 upward, the resistance when the two ridges 9 and 17 are slidably contacted with each other is mitigated. Therefore, as described above, the lid body 13 may be locked in the open position. The operation resistance when the lid 13 is opened is not significantly increased, and the lid 13 can be locked in the open position by a slight operation force.

Similarly, when the lid 13 locked in the open position is slid in the closed position, the corner portions 15, 1 whose horizontal cross section is substantially curved are similarly formed.
By the elastic deformation of 5 as appropriate, the resistance when the second second ridge 17 gets over the first ridge 9 is relieved. Therefore, the opening / closing operation of the lid 13 can be performed by a slight operation force without causing a significant increase in the operation resistance when the lid 13 is closed.

On the other hand, after the second ridge 17 has passed over the first ridge 9, since the corner portions 15 and 15 are elastically restored, the second ridge 17 has a sufficient overlap margin. The lid 13 is securely retained in the open position by being locked to the upper portion of the first protrusion 9.

Moreover, since both side edges 19, 19 of the lid body 13 move while slidingly contacting the guide protrusions 12 provided on the post body,
The lid 13 has a sufficient amount of elastic deformation in the general portion between the both side edges 19, 19. Furthermore, since the two ridges 9 and 17 have curved surfaces in contact with each other, when the second ridge 17 crosses over the first ridge 9, the two ridges 9 and 17 contact each other. The line is in contact. Therefore, due to the sufficient elastic deformation amount and the line contact state, it is possible to further reduce the resistance when the second protrusion 17 rides over the first protrusion and improve the operability.

Further, since the guide protrusion 12 is formed by the step between the extending portion 11 provided on the rear wall 4 and the left and right side walls 3, 3, the extending portion 11 is formed on the rear wall 4. The left and right side walls
The guide convex portion 12 can be formed with a simple structure of joining the guide convex portions 3 and 3.

When the lid 13 is moved to reach the closed position as described above, the slit 18 provided in the lid 13 is fitted to the fitting convex portion 10 to close the lid 13. It is possible to prevent rattling at the position.

In the above-described embodiment, the first protrusion 9 forms the fixed side locking portion provided on the front wall 2 of the post body 1, and the second protrusion provided on the lid 13 is formed. Although the movable side locking part is formed by 17, both of the locking parts are lids, such that one of the locking parts is a convex part and the other is a concave part.
Other structures may be used as long as they can lock the lid 13 when the cover 13 reaches the open position.

As described above, according to the present invention, the fixed side locking portion is provided on the vertical wall provided on the post body, and the lid body is integrally formed on the front surface portion along the vertical wall and on both sides of the front surface portion. And a movable side locking portion that engages with the fixed locking portion when the lid body reaches the open position on the front surface portion.

Therefore, it is possible to hold the lid body in the open position and easily take out the postal matter inside the post body from the opening portion, and the lid body can be appropriately elastically deformed by the curved corner portion. Since it is possible, the smoothness at the time of opening the lid is impaired due to the resistance at the time of locking the locking portion, and the smoothness at the time of opening the lid by the resistance at the time of unlocking. It is possible to avoid the inconvenience of being damaged.
Therefore, it is possible to ensure the operability when opening and closing the lid while ensuring the ease of taking out postal matters and the like.

Further, the fixed-side locking portion is a first ridge that is provided on the back surface of the vertical wall and extends in the horizontal direction, and the movable-side locking portion is the opening formed on the lid body. The second, which gets over the first ridge and reaches the upper part of the first ridge when reaching the position
It was a ridge. Therefore, the resistance when the ridges are in sliding contact with each other can be effectively alleviated by the elastic deformation of the lid body, and the two ridges are curved by making the surfaces of the ridges that are in phase contact with each other curved. The resistance when the strips contact can be reduced.

For this reason, the opening / closing operation of the lid can be performed more smoothly, and when the second ridge passes over the first ridge, the elastic return of the lid causes the second ridge to move. Is reliably locked to the upper portion of the first protrusion, and the holding of the lid body in the open position can be further ensured.

In addition, since the guide protrusions extending in the vertical direction are formed on the side wall of the post body, and the both side edges of the lid body are slidably contacted with the guide protrusion portions, the lid body is provided between the both side edges. In this case, the entire surface is elastically deformed, and it is possible to secure a sufficient elastic deformation amount in the lid. Therefore, with this sufficient amount of elastic deformation, the resistance is further reduced,
Operability can be improved.

Further, extending portions are provided on both sides of another vertical wall facing the vertical wall, the extending portions are arranged inside the side wall, and the side edges are formed by a step between the side wall and the extending portion. Since the protrusions that are in sliding contact with each other are formed, it is possible to form the guide protrusions with a simple configuration in which an extended portion is formed on the other vertical wall and is joined to the side wall.

Further, when the lid body reaches the closed position, the slit provided on the lid body is fitted into the convex portion provided on the post body, so that the rattling of the lid body at the closed position is prevented. It is also possible to do.
