A magnet 12 for magnetically attaching the take-out door 4 in a state where the take-out port 3 is closed is provided below the take-out opening 3 and at the center in the width direction. An inclined piece 13 is disposed on the lower surface inside the post 1 such that the inclined piece 13 is located lower as it goes backward. The inclined piece 13 slides the mail or the like stored inside the post 1 near the outlet 3 and positions it.

The take-out opening 3 is opened and closed by a take-out door 4. The take-up door 4 has its upper part pivotally supported on both side walls 1a of the post 1 near the take-out opening 3, and is rotatable up and down. Is provided. The take-out door 4 is a plate-like body formed by arranging a light-transmitting plate 14 at the center and a metal plate 15 at the periphery thereof so that the inside of the post 1 can be visually checked. Handle 29 is provided. The pivotal support structure of the take-out door 4 to the side wall 1a of the post 1 is configured by a rotatable fitting of a pivot shaft 31 provided on the side wall 1a of the post 1 and a bearing 34 provided on the take-out door 4. . When the take-out door 4 is turned upward from below, the take-out opening 3 is opened, and when the take-out door 4 is turned downward from above, the take-out opening 3 is closed. Is magnetically attached by the magnet 12. The downward movement of the take-out door 4 is effected by the weight of the take-out door 4. For example, the pivot shaft 31 and the bearing 34, which constitute a pivot portion of the take-out door 4 to the side wall 1 a of the post 1, are provided. It is preferable to arrange a damper body that serves as a resistance to the rotation of the pivot shaft 34 between the two and that the lower rotation of the take-out door 4 can be performed slowly.

The post 1 thus configured is provided with temporary fixing means for temporarily fixing the take-out door 4 with the take-out opening 3 opened. The temporary fixing means includes a fitting hole 5 provided in one of the post doors 4 or the post side walls 1a near the take-out port 3, and a ball provided in the other of the take-out door 4 or the post side walls 1a near the take-out port 3. The ball 6 urged in the fitting hole insertion direction is inserted into the fitting hole 5 when the removal door 4 opens the removal port 3. In this example, the ball 6 is housed in the ball housing 9 shown in FIG. 4, and the fitting hole 5 (FIG. 1)
Are provided on the ball receiving member 7 shown in FIGS. 6 and 7 and are unitized separately from the post 1 so as to improve the workability of attaching the temporary fixing means to the post 1. I have. Hereinafter, the temporary fixing means will be described in detail.

The ball storage cylinder 9 is formed in a bottomed cylindrical shape having an opening 9a at one end and a bottom portion 9b at the other end. The ball 6 is loosely fitted inside the cylinder, and the diameter of the opening 9a is adjusted to the ball diameter. Ball 6 and the bottom 9b.
And an elastic spring 10 is interposed therebetween. The ball 6 is urged by an elastic spring 10 in the direction of the opening 9 a of the ball housing 9 so that a part of the ball 6 projects outward from the opening 9 a of the ball housing 9. It is housed inside so that it can roll freely. The elastic spring 10 is formed of a coil spring, and is arranged so that the inner diameter portion of the coil spring is externally fitted to a spring external fitting cylinder 35 protruding from the center of the bottom portion 9b of the ball housing 9 in the opening direction. .

The opening 9a of the ball storage cylinder 9 has a post side wall 1a at an end in the width direction of a storage groove 16 which is formed at the upper end of the take-out door 4 and extends in the width direction and has a concave shape in a side view. (FIG. 5). The ball storage cylinder 9 is attached to the take-out door 4 by the U-shaped receiving portion 1 formed on the side surface of the ball storage cylinder 9.
Positioning is performed by fitting the end of the groove bottom 16a of the storage groove 16 in the width direction to the groove 8 and the plate-shaped contact piece 17 formed on the side surface of the ball storage tube 9 is brought into contact with the groove bottom surface 16a. The mounting hole 19 formed in the contact piece 17 has a groove bottom surface 16a.
This is performed by inserting a fixing tool such as a screw screwed into the device.

The ball receiving member 7 has a ball rolling contact portion 7a which rolls while the ball 6 is in contact with the surface of the ball receiving member 7 and a fixed portion 7b which is attached to the side wall 1a of the post 1 near the take-out opening 3 in the left and right directions. It is a resin molded product that is attached and integrated.
The ball transfer portion 7a is formed with a tapered portion 8 at an upper portion thereof and a fitting base hole 21 recessed from the front surface to the rear surface at a lower portion thereof. The tapered portion 8 is formed so as to gradually increase in thickness as it goes downward, and the fitting base hole 21 is provided with a metal cylindrical fitting tube 23 so as to cover the inner peripheral surface thereof. Thus, the fitting hole 5 is formed. As described above, the fitting hole 5 is provided with the metal fitting tube 23 to improve the wear resistance and the load resistance against the fitting of the ball 6. The fitting tube 23 is arranged in the fitting base hole 21 by press-fitting or tapping. At this time, at least the ball 6 is fitted and released in the fitting hole 5 without resistance. The fitting tube 23 is arranged so as not to protrude from the surface of the ball transfer portion 7a [FIG.
(B)]. At the lowermost end of the ball transfer portion 7a, a regulating protrusion 28 is provided on the surface. This regulating protrusion 28
Is for restricting the operating range of the ball 6 rolling on the ball rolling contact portion 7a and, consequently, the range of vertical rotation of the take-out door 4.

The ball receiving member 7 is attached to an appropriate position on the side wall 1a of the post 1 near the outlet 3. The attachment of the ball receiving member 7 to an appropriate position of the side wall 1a of the post 1 is performed by interposing an attachment member 20 (FIGS. 8B and 8C) between the back surface of the fixing portion 7b and the side wall 1a of the post 1. A fixing tool such as a screw screwed to the side wall 1a of the post 1 is inserted into a pair of mounting holes 22 provided at the upper and lower positions of the fixing portion 7b. The position of the side wall 1a of the post 1 near the take-out opening 3 means that when the mounting door 4 is rotated upward, the ball 6 of the mounting door 4 is moved from the tapered portion 8 of the ball rolling portion 7a to the fitting hole. It is the position where it comes into contact with it to reach 5.

The provisional fixing means having the above-mentioned structure is used to rotate the take-out door 4 so that the take-out door 3 is opened and the take-out opening 3 is opened by fitting the ball 6 into the fitting hole 5 in conjunction with the ball 6. This is to perform temporary fixing. Hereinafter, the opening and closing rotation of the post 1 provided with the temporary fixing means to the take-out opening 3 of the take-out door 4 will be described in detail together with the operation of the temporary fixing means.

To open the outlet 3, the user grasps the handle 29 of the outlet door 4 and lifts it upward, and pivots the outlet door 4 upward about a pivotal portion to the outlet 3. To do this. When the take-out door 4 is rotated upward, the ball 6 provided at the upper end of the take-out door 4 traces an arc centered on a pivotal portion of the take-out door 4 to the take-out opening 3 from above to below [FIG. (A) Medium X] is drawn. In the trajectory X, the ball 6 comes into contact with the ball contact portion 7a of the ball receiving member 7. The ball 6 first comes into contact with the tapered portion 8 provided above the ball contact portion 7a. Finally, it is fitted into the fitting hole 5 provided in the lower part of the ball rolling contact portion 7a. here,
When the ball 6 makes elastic contact with the tapered portion 8, the tapered portion 8
Is gradually increased in thickness as it goes down, so that the ball 6 can smoothly contact the ball receiving member 7 and move along with the movement of the ball 6 downward. The elastic spring 10 that biases the spring gradually has a large spring reaction force. When the ball 6 moves downward and overlaps the fitting hole 5, the ball 6 is biased in the fitting hole insertion direction by the spring reaction force provided in the elastic spring 10 so that the ball 6 is fitted into the fitting hole 5. 5, the ball 6 is fitted into the fitting hole 5, and the take-out door 4 with the take-out port 3 opened is temporarily fixed.

On the other hand, in order to close the take-out port 3, the user releases the temporary fixing of the take-out door 4 temporarily fixed by the temporary fixing means. Then, the take-out door 4 that has been temporarily loosened is naturally rotated downward by its own weight around the pivot portion to the take-out port 3, and the take-out door 4 that closes the take-out port 3 is magnetically attached by the magnet 12. You. As described above, since the take-out door 4 is temporarily fixed by fitting the ball 6 into the fitting hole 5, the temporary fixing of the take-out door 4 is performed by fitting the ball 6 into the fitting hole 5. Can be canceled. The fitting of the ball 6 into the fitting hole 5 is performed by urging the ball 6 by the elastic spring 10, that is,
When the force against the above-mentioned bias is applied to the ball 6, the fitting of the ball 6 into the fitting hole 5 is released. To do so, the user only has to press the take-out door 4 downward with a certain force. In other words, when the take-out door 4 is to be turned downward, the ball 6 provided at the upper end of the take-out door 4 tends to move downward. The ball 6 rolls so as to ride on the surface of the portion 7a, and the fitting of the ball 6 into the fitting hole 5 is released. Thereafter, as described above, the take-out door 4 rotates downward by its own weight, and the ball 6
Is rolled upward while resiliently contacting the surface of the ball rolling contact portion 7a, and the take-out door 4 turned downward closes the take-out port 3.

The opening / closing operation of the take-out port 3 in the post 1 provided with the temporary fixing means as described above is performed only by the up-and-down turning operation of the take-out door 4. That is, in the post 1 of the present example, the opening and closing operation of the outlet 3 is performed by a one-stage operation. In the post 1 'provided with the temporary fixing means of the prior art, the post is taken out by a two-stage work operation in which the user uses both the work of turning the take-out door 4 up and down and the work of sliding the take-out door 4 in the front-rear direction. Since the opening / closing operation of the opening 3 is performed, the opening / closing operation of the outlet 3 of the post 1 in this example can be simplified as compared with the opening / closing operation of the conventional opening 1 of the post 1 '. This improves the operability of the user in opening and closing the outlet 3. In particular, the complicated opening / closing operation of the take-out port 3 of the prior art, such as sliding the take-out door 4 in the front-rear direction at the take-out door 4 originally rotated, is not the opening / closing operation of the take-out port 3 of the present invention. This eliminates the need for the user to feel complicated in the work. Here, the temporary fixing of the take-out door 4 by the temporary fixing means of this embodiment is performed by inserting the biased ball 6 into the fitting hole 5.
When the overload is applied to the take-out door 4, the biased ball 6 rolls into the fitting hole 5, so that it is easily inserted from the fitting hole 5. The structure described above allows the overload to escape and prevents the take-out door 4 etc. from being damaged, and allows the user to safely post without worrying about the take-out door 4 etc. being damaged. 1
Can be opened and closed.

FIG. 9 shows the above-described post 1 of the present embodiment.
Is fixed to the block wall 27. 24 in the figure
Reference numeral 25 denotes a base for making up the front surface of the inlet 2, and reference numeral 25 denotes mortar for filling a gap in a front recess formed below the inlet 2 of the post 1. Note that a spacer block 26 (see FIGS. 1 and 3) may be attached to the front recess of the post 1 instead of the mortar. When the post 1 is fixed to the block wall 27 in this way, for example, the front and rear thickness of the block wall 27 is longer than the front and rear length of the post 1, and the rotation of the take-out door 4 of the post 1 causes the block wall to rotate. If it is obstructed by the rear end portion 27a of the block wall 27, the rear end portion 27a of the block wall 27 may be removed.

In the embodiment of the present invention described above, the ball 6 is arranged on the take-out door 4 and the take-out opening 3
Although the example in which the fitting hole 5 is arranged in the nearby post side wall 1a is shown, on the contrary, it is also possible to take out the fitting hole 5 in the take-out door 4 and arrange the ball 6 in the take-out door 4. is there. Here, when the fitting hole 5 is directly formed in the door side surface formed in the front and back direction of the take-out door 4, as shown in FIG. 10, the corner formed by the front or back surface and the door side surface is rounded. It is also preferable to apply it to 4a. The R shape 4a allows the ball 6 to make a smooth contact with the ball 6 as in the case of the tapered portion 8 according to the embodiment of the present invention, so that the take-out door 4 can be smoothly rotated. Also in this case, the fitting hole 5 may be provided in a separate object from the take-out door 4 like the ball receiving member 7 as in the example of the above embodiment.

[0025]

As described above, according to the first aspect of the present invention, as described above, the provisional fixing means includes the fitting hole 5.
And a ball urged in the insertion direction of the fitting hole, so that the ball is inserted into the fitting hole when the take-out door opens the take-out opening. Since the ball is arranged and the fitting hole is arranged on the other side, when the take-out door is turned upward, the ball is inserted into the fitting hole and the take-out door is temporarily fixed with the take-out opening open. In addition, contrary to the above operation, when the take-out door is rotated downward, the fitting between the ball and the fitting hole is released, and the take-out door closes the take-out opening,
That is, the opening / closing operation of the take-out opening of the post of the present invention is performed only by the vertical turning operation of the take-out door, that is, it can be performed by a one-stage work operation. The opening / closing operation of the outlet can be simplified as compared with the opening / closing operation of the outlet by a work operation, and furthermore, the complicated extraction of the conventional technology such as sliding in the front-rear direction at the inherently rotating extraction door. Since the opening / closing operation of the opening is excluded from the opening / closing operation of the outlet of the present invention, the user does not have to feel complicated in the opening / closing operation of the outlet. The temporary fixing is performed by fitting an energized ball into a fitting hole, and when an overload is applied between the ball and the fitting hole, the above-described bias is applied. Ball Since it rolls into the mating hole and is easily removed from the fitting hole, the above-mentioned overload can be released to prevent breakage of the take-out door and the like. The opening and closing operation of the outlet of the post can be performed without worrying about damage.

According to the second aspect of the present invention, in addition to the effect of the first aspect, the ball is arranged on the take-out door and the fitting hole is arranged on the side wall of the post, so that the ball receiving portion is brought into elastic contact with the ball. Since the member is attached to the post side wall and the fitting hole is formed in the ball receiving member, instead of directly forming the fitting hole by piercing the post side wall or the like, the ball receiving member having the fitting hole formed in advance is used. A fitting hole can be easily provided at an appropriate position on the post side wall by an operation of attaching the member to the post side wall, that is, the fitting hole can be unitized in a ball receiving member that is separate from the post, The workability of attaching the temporary fixing means to the post is improved.

According to the third aspect of the present invention, in addition to the effect of the second aspect, the ball receiving member gradually moves toward the end portion of the ball contact portion as it goes inward from the end portion. Since the tapered portion is provided so as to increase the thickness, when the ball is elastically contacted with the ball receiving member, the tapered portion is slid so that the ball is smoothly elastically contacted with the ball receiving member. Thus, the rotation of the take-out door can be smoothly performed.

According to the fourth aspect of the invention, in addition to the effect of the second aspect, a ball storage cylinder formed into a bottomed cylindrical shape and having a ball loosely fitted inside the cylinder is taken out of the upper portion of the door. The ball is urged in the opening direction by an elastic spring interposed between the bottom of the ball storage cylinder and the ball, and the opening is formed to be smaller than the outer diameter of the ball. Since the ball is made to protrude outward from the above-mentioned opening, the ball constituting the temporary fixing means can be unitized in a ball storage cylinder which is separate from the post, and the workability of attaching the temporary fixing means to the post is improved. Is what you do.
