[0003] [Patent Document 1] JP 2021-131838 A Summary of the Invention [Problem to be solved by the invention]

[0004] Here, a vertically extending shape is often adopted for the mailbox throwing device. However, such a shape keeps the center of gravity at a high position. Therefore, in order to improve stability, there is a method of fixing the mailbox throwing device to a mounting surface such as the ground, but this method cannot be adopted in cases where the mailbox throwing device cannot be fixed to the ground due to the installation location, or in the case of a mobile mailbox throwing device whose installation location is expected to change. It is necessary to lower the center of gravity and improve the stability of such stationary or mobile mailbox throwing devices as well.

[0005] SUMMARY OF THE PRESENT INVETION It is an object of the present invention to provide a mailbox depositing device that can lower the center of gravity and improve stability, whether it is a stationary type or a mobile type. [Means for solving the problem]

[0006] A mailbox-dropping device according to one embodiment of the present invention comprises a housing having a storage section capable of storing parcels dropped through a mailbox slot, an opening / closing door that is openably and closably attached to the housing and opens and closes the storage section, an unlocking section that is arranged across the storage section and the bottom of the housing and mechanically unlocks the opening / closing door, and a bottom cover that is arranged on the bottom and protects the unlocking section, and a weight for lowering the center of gravity of the housing is fixed to the bottom plate that separates the storage section and the bottom of the housing so as to avoid at least one of the unlocking section and the bottom cover.

[0007] In such a mailbox throwing device, a weight is fixed to the bottom plate that separates the storage section from the bottom of the housing, lowering the center of gravity of the mailbox throwing device. This makes it possible to lower the center of gravity and improve stability in both stationary and mobile mailbox throwing devices.

[0008] The weight may be disposed on the bottom and have a cutout to avoid the bottom cover. This allows the space at the bottom of the housing to be used efficiently. Also, by disposing the weight on the bottom of the housing, the capacity of the housing can be sufficiently secured.

[0009] A fastening notch that extends in the predetermined direction and engages with a first fastening member for fixing the weight to the bottom plate may be provided on one side of the weight in the predetermined direction, and a long hole that extends in the predetermined direction and engages with a second fastening member for fixing the weight to the bottom plate may be provided on the other side of the weight in the predetermined direction. In this way, after the mailbox throwing device is toppled, the first fastening member is provisionally fastened to the bottom plate, and with the fastening notch of the weight fitted into the first fastening member, the second fastening member is passed through the long hole of the weight and fastened to the bottom plate, and the first fastening member is finally fastened to the bottom plate, thereby easily fixing the weight to the bottom plate at the bottom of the housing.

[0010] The weight may be disposed in the storage section and have a notch that avoids the unlocking section. This allows the weight to be easily fixed to the bottom plate in the storage section of the housing with the door open, without having to tip the mailbox device over.

[0011] The weight may have a structure in which a plurality of metal plates of the same shape are stacked together. This allows each metal plate to be handled individually even if the weight of the weight as a whole is heavy. As a result, the weight can be easily transported and removed. Effect of the Invention

[0012] According to the present invention, it is possible to provide a mailbox dropping device that can lower the center of gravity and improve stability, whether it is a stationary type or a mobile type. [Brief description of the drawings]
