Description

[0001]
BACKGROUND OF THE INVENTION
The invention of this application relates to the structure of a post for receiving a delivery such as mail or newspaper. More specifically, the present invention relates to a post structure in which a flat door for collecting a delivery item from the back side is accurately attached.
[0002]
[Prior art]
For example, a post as illustrated in the rear perspective view of FIG. 4 is installed as a facility for receiving delivery items such as mail and newspapers at the gate pillar, entrance pole, or entrance door of a front door of a house or the like. Yes.
The post is provided with a door (20) at the opening on the back side of the post body (10), and the delivery is collected by opening the door (20). Bending rim pieces (21a-d) are formed around the door (20), and an upper hinge (31) and a lower hinge (32) disposed on the post body (10), and the door (20). The bent rim pieces (21a) and (21c) are rotatably supported by rotating shafts (40) and (50), respectively.
[0003]
Further, a stopper member (60) is disposed from the inner wall surface (11) of the post body (10) to the door back surface (22). As illustrated in FIG. 5, when the door (20) is opened, the stopper member (60) is configured such that when the door (20) rotates more than a certain angle, the claw portion (61) at the tip is moved to the door (20 ) And the bent rim piece (21b) to stop the rotation of the door (20).
[0004]
Furthermore, as shown in FIG. 4, the claw portion (61) of the stopper member (60) supports a U-shaped projection piece (23) on the back surface (22) of the door, thereby the door member. The downward bent rim piece (21c) of (20) does not come into pressure contact with the lower hinge (32), and can smoothly rotate.
[0005]
[Problems to be solved by the invention]
In the conventional post structure as illustrated in FIG. 4, the stopper member (60) is configured so that the claw portion (61) of the stopper member (60) accurately contacts the protruding piece (23) on the door back surface (22). Need to be fixed. Therefore, in the conventional post structure, as illustrated in FIG. 5, a slit (13) is provided in the opening rim (12) of the post body (10), and a stopper member (60) is provided from the slit (13). The flat plate portion (62) was fixed to the inner wall surface (11).
[0006]
However, the processing of the slit (13) in the opening rim (12) and the attachment and fixing of the stopper member (60) through the slit (13) are extremely troublesome operations.
Moreover, since the flat plate portion (62) of the stopper member (60) and the inner wall surface (11) are fixed by spot welding, there is a risk that positional displacement will occur during fixing. For this reason, it is necessary to use some jig or the like at the time of welding, which has been a cause of further complicated processes.
[0007]
Further, in order to prevent the bent rim piece (21c) of the door (20) and the lower hinge (40) from being pressed against each other due to the displacement of the stopper member (60), a groove ( 51) is processed, and an E-ring (52) is fitted into the groove (51), and the friction between the bent rim piece (21c) and the lower hinge (40) is reduced by the E-ring (52). It was. However, the use of the E-ring (52) complicates the assembly process and makes it difficult to replace the door (20).
[0008]
The invention of this application was made in view of the circumstances as described above, and eliminates the problems of the conventional post structure, and a post structure that can easily attach and fix the stopper member at an accurate position. The issue is to provide.
[0009]
[Means for Solving the Problems]
As an invention for solving the above-mentioned problems, this application has a post body and a door, and the upper and lower edges of the door are rotatably supported by the upper and lower hinge rotation shafts of the opening end of the post body. The claw part of the stopper member arranged from the original inner wall surface of the post to the back side of the door comes into contact with the bent rim piece around the door, thereby stopping the rotation angle of the door at a fixed position. Provided is a post structure in which a claw portion of a member supports a protruding piece on the back surface of the door, and the stopper member is disposed on a vertical piece extending from the lower hinge. To do.
[0010]
In this post structure, the stopper member is integrated with the vertical piece extending from the lower hinge, or the stopper member is separate from the vertical piece extending from the lower hinge. A preferred embodiment is that it is attached at a position corresponding to the attachment position mark.
Furthermore, in the post structure of the present invention, another preferred embodiment is that the pivot shaft of the lower hinge is a pin member, and the upper end refracting portion of the pin member is fixed by a pressing metal fitting.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example is shown along the attached drawing and the post structure of this invention is explained in more detail.
[0012]
【Example】
FIG. 1 is a rear perspective view showing an embodiment of a post structure of the present invention, and FIG. 2 is a side sectional view of the post structure and an enlarged view of a main part thereof.
As illustrated in FIGS. 1 and 2, in the post structure of the present invention, a door (20) is provided at the back side opening of the post main body (10) as in the conventional example, and the door (20) Bending rim pieces (21a to 21d) are formed around the upper and lower hinges (31) and (70) disposed on the post body (10), and the folding rim pieces ( 21a) and 21c are rotatably supported by rotating shafts 40 and 80, respectively.
[0013]
A stopper member (90) is disposed from the inner wall surface (11) of the post body (10) to the door back surface (22). The stopper member (90) is integrated with a vertical piece (71) extending from the lower hinge (70), and the lower hinge (70) is integrated with the bottom surface (14) and the inner wall surface (11) of the post body (10). ), The stopper member (90) is fixed at a position where the claw portion (91) accurately supports the protruding piece (23). Therefore, it is not necessary to position through the slit of the opening rim (12) as in the conventional example, and as shown in FIG. 3, the claw portion (91) is moved beyond the opening rim (12). It can be extended to the door back surface (22).
[0014]
With the configuration as described above, the stopper member (90) can be easily attached and fixed at an accurate position.
The stopper member (90) may be separate from the lower hinge (70). In that case, for example, a positioning mark can be formed on the vertical piece (71) of the lower hinge (70), and the stopper member (90) can be fixed in accordance with the mark. Further, the upper end edge of the vertical piece (71) can be used as a positioning mark, and the upper end edges of the vertical piece (71) and the stopper member (90) can be matched.
[0015]
Further, in the post structure illustrated in FIGS. 1 and 2, the lower rotation shaft (80) is a pin member, and the upper end refracting portion (81) of the pin member is a press fitting (82) and a screw ( 83). That is, in the post structure of the present invention, as described above, since the claw portion (91) of the stopper member (90) accurately supports the protruding piece (23), the door (20) does not shift downward. . For this reason, it is not necessary to interpose an E ring, a washer, or the like on the lower rotation shaft (80), and a simple configuration illustrated in FIGS. 1 and 2 can be obtained. As a result, work steps such as attachment of the pivot shaft (80) and replacement of the door (20) are greatly simplified.
[0016]
Of course, the present invention is not limited to the above examples, and it goes without saying that various configurations and the like are possible.
[0017]
【The invention's effect】
As described above in detail, according to the invention of this application, the stopper member can be easily fixed at an accurate position, and the work process such as assembly and replacement of the door can be simplified.
