Description

[Detailed explanation of the idea] The present invention relates to a ningaeshi that can do a handstand.

Recently, there have been many thefts where thieves break into housing complexes through balconies or second-floor windows.
Installing a ninjashi to prevent theft at the entry point is the simplest and best way to ensure peace of mind, as thieves can see this from the outside and give up trying to climb in. Futons and other items are often hung to dry on balconies and second-floor windows, so if a shingaeshi was installed, there was a problem in that the futons and other items could not be dried. The present invention was devised to solve such problems and provide a two-stage invertable Ninogaeshi that has the security function of a normal Ninogaeshi when it is stood up, and can dry futons, etc. when it is laid down. be.

The present invention will be described below with reference to the drawings. Reference numeral 1 denotes a base frame having a generally U-shaped longitudinal section and fixed on a balcony or window frame A in the longitudinal direction (left-right direction in FIG. 1). 2, 2, . . . are inverted shafts provided in the base frame 1 at approximately equal intervals in a direction perpendicular to the longitudinal direction. 3,3
. . . is a sprocket that is rotatably fitted loosely into the inverted shafts 2, 2 . Reference numerals 4, 4, . . . indicate cylindrical inverted cylinder shafts that are integrally fixed to the sprockets 3, 3, . Reference numerals 5, 5, . . . are sharpened rods extending perpendicularly to each inverted cylinder shaft 4 and having sharpened tips.
An inverted gear 6 is fixed to the sprocket 3 at the outermost position, and is loosely fitted onto the inverted shaft 2 so as to rotate together with the sprocket 3. 7 is a driving gear that meshes with the inverted gear 6. Reference numeral 8 denotes a grip rotation rod provided by extending one end of the rotation shaft 9 of the driving gear 7 onto the base frame 1 and bending it laterally at a right angle. Reference numeral 10 denotes a grip portion provided perpendicularly to the grip rotation rod 8 in the front direction (downward in FIG. 2). 11 is a chain wrapped around the sprocket 3. Reference numeral 12 denotes an abutment protrusion surface provided at a contact position of the grip rotation rod 8 corresponding to the upright position of the sharpened rod 5. The other reference numeral 13 is a lock for locking the grip rotation rod 8.

Because the present invention has such a structure, when the present invention is attached to a balcony or window frame and the grip portion 10 is rotated at night or when one is away, the sprockets 3, 3 are connected via the driving gear 7 and the inverted gear 6. ... rotate all at once and rotate together with the inverted cylinder shaft 4, so that the sharpened rods 5 can be raised all at once from inside the base frame 1. If the abutting protrusion surface 12 is provided at the position where the sharpened rod 5 stands vertically, when the rotation of the grip rotation rod 8 stops until it comes into contact, the sharpened rods 5 will stop all at once in a vertically standing position. In this state, the rotating rod 8 and the abutment protrusion surface 12 can be gripped as appropriate to demonstrate the function of the conventional Ningaeshi.
When locked with lock 13, even at night,
Also, you can feel safe even when you are away. Also, next time you want to dry a futon or the like on the balcony window frame A, or when there is no need for Ninagaeshi, release the lock and rotate the grip turning rod 8 in the opposite direction. , 5... can be laid down all at once in the direction shown by the dashed line on the side and retracted into the base frame 1, making it possible to hang a futon or the like in the same manner as before. Therefore, the present invention was implemented, and the surface of the base frame 1 was cut out only at the portion where the sharp rods 5, 5, . . . were to stand upside down. For example, if you cover it with a colorful synthetic resin board, it will not detract from the aesthetics even if used on a balcony, and even though it is equipped with a shingle, which has a strong crime prevention effect, it is not possible to dry futons, etc. When it is prudent to do so, the ningaeshi can be easily lowered, and it is not an eyesore and is a very useful device for preventing theft.
