[0003] The following Patent Document 1 discloses a configuration in which a hook portion is provided on the body of a fire control panel, such as a door, and a handset can be hung on the hook portion. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2005-234897 A Summary of the Invention [Problem to be solved by the invention]
[0005] However, in the handset described in Patent Document 1, the handset may fall off the hook due to vibration, contact with the handset, etc. Also, some designs have been designed to make the handset less likely to slip off by attaching a packing with a high friction coefficient to the handset and bringing the packing into contact with the body such as a door, but this has the problem of not being able to sufficiently prevent the handset from falling off.
[0006] The present invention has been made in consideration of the above circumstances, and provides a handset support structure and a fire control panel that can prevent the handset from falling off. [Means for solving the problem]
[0007] In order to achieve the above object, the present invention employs the following means. That is, the handset support structure according to the present invention includes a handset detachably engaged with a main body, a fall prevention part that prevents the handset from moving in a removal direction in which the handset is removed from the main body, and an upper plate portion disposed above the main body portion and having a locking hole extending therethrough in the vertical direction; Equipped with The fall-off prevention portion has a pressing portion that presses an upper portion of the handset downward, and a locking portion connected to a front end portion of the pressing portion, and the locking portion is locked in the locking hole. It is characterized by: In addition, the handset support structure of the present invention comprises a handset removably engaged with a main body portion, a storage recess for accommodating the handset internally, and an anti-dropout portion for restricting movement of the handset in a removal direction in which the handset is removed from the main body portion, the anti-dropout portion having a fixed plate portion configured as a plate that is attached in contact with a rear plate portion located on the opposite side of the storage recess in the removal direction, and a pressing portion that presses an upper portion of the handset downward, the fixed plate portion being exposed when viewed from the front when the handset is not engaged with the main body portion, and being screwed into the rear plate portion in a position that is hidden by the handset when viewed from the front when the handset is engaged with the main body portion.
[0008] In the handset support structure configured in this manner, the fall-prevention section prevents the handset from moving in the direction of removal from the main body, thereby preventing the handset from falling off. In addition, the upper part of the handset is pressed downward by the pressing portion of the fall prevention portion, so that the handset is securely engaged with the main body, and the handset is further prevented from falling off the main body. In addition, the locking part connected to the front end of the pressing part is locked into a locking hole in the upper plate part located above the main body part, so that the pressing part will not come off and the upper part of the handset can be pressed downward reliably.
[0011] In the handset support structure according to the present invention, the pressing portion may be gradually inclined downward as it extends forward, and may be elastically deformable in the vertical direction.
[0012] In the handset support structure constructed in this way, the pressing part gradually slopes downward as it approaches the front and is elastically deformable in the vertical direction, so that when the handset is to be removed from the main body, the pressing part is simply deformed upward to move the handset upward, making it easy to remove the handset.
[0015] In addition, the support structure for a handset according to the present invention may include a rear plate portion arranged behind the main body portion and to which the main body portion is fixed, and the anti-fall-out portion may have a fixing portion fixed to the rear plate portion.
[0016] In the handset support structure configured in this manner, the fixing portion of the fall-prevention unit is fixed to the rear plate portion disposed behind the main body portion, and therefore the fixing portion of the fall-prevention unit is not noticeable when viewed from the front because it is hidden by the main body portion.
[0017] A fire receiver according to the present invention is characterized by comprising any one of the handset support structures described above.
[0018] In the fire control panel configured in this manner, the drop prevention section prevents the handset from dropping off from the main body section. Effect of the Invention
[0019] According to the handset support structure and fire control panel of the present invention, it is possible to prevent the handset from falling off. [Brief description of the drawings]

[0057] Furthermore, even if the handset 60 is simply pulled toward oneself without first lifting it upward, the handset 60 is pressed downward by the pressure plate portion 46 of the anti-fall-off material 40, and the engagement projection 51a of the telephone body 50 engages with the engagement recess 62a of the handset 60, so that the handset 60 will not come off the telephone body 50.
[0058] In addition, the pressure plate 46 is gradually inclined downward as it approaches the front, and is also elastically deformable in the vertical direction. Therefore, when removing the handset 60 from the telephone body 50, the pressure plate 46 is simply deformed upward to move the handset 60 upward, making it easy to remove the handset 60.
[0059] In addition, the locking plate 48 connected to the front end of the pressing plate 46 is locked in the locking hole 31h of the upper plate 31 disposed above the telephone body 50. Therefore, the pressing plate 46 will not come off, and the upper part of the handset 60 can be reliably pressed downward.
[0060] Moreover, the fixing plate portion 41 of the fall-prevention member 40 is fixed to the rear plate portion 34 disposed at the rear of the telephone body 50. Therefore, when viewed from the front, the fixing plate portion 41 of the fall-prevention member 40 is hidden by the telephone body 50, and therefore the fixing plate portion 41 is not noticeable.

[0070] With the handset 60 attached to the telephone body 50, the pressure plate 46B and the reinforcing plate 49 of the anti-dropout member 40B are displaced upward as shown by the solid line from their original positions shown by the two-dot chain line. The pressure plate 46B presses the top surface of the upper head 62 of the handset 60 downward.
[0071] When removing the handset 60 from the telephone body 50, the handset 60 is lifted upward once to release the engagement between the engagement recess 62a of the handset 60 and the engagement projection 51a of the telephone body 50, and the handset 60 is then pulled towards you. When the handset 60 is lifted upward once, the pressure plate 46B and the reinforcing plate 49 of the anti-dropout member 40B are displaced further upward. When the handset 60 is removed from the telephone body 50, the anti-dropout member 40B is elastically deformed and returns to its original state as shown by the two-dot chain line.
[0072] According to the fire prevention device 100 configured in this manner, the handset 60 is prevented from falling off from the telephone body 50 by the fall-off prevention material 40B.
[0073] In addition, the upper part of the handset 60 is pressed downward by the pressure plate 46B of the anti-dropout member 40B.
