【Example】

 Hereinafter, a specific structure of the door guard fitting of the present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a plan view showing an embodiment of a door frame side locking metal fitting having a U-shaped guide arm, FIG. 2 is a side view of the door frame side locking metal fitting shown in FIG. 1, and FIG. 3 is a door guard. FIG. 4 is a perspective view showing an example of a usage state of the metal fitting, FIG. 4 is a perspective view of a usage state when the door is closed, and FIG. 5 is a perspective view when a U-shaped guide arm is sandwiched between the doors.

In the figure, reference numeral 1 shows a door-side locking metal member having a bulged portion 2 protruding from its tip. In the door side locking metal fitting 1 of the illustrated embodiment, an arm rod 5 is obliquely provided on an upper surface of a pedestal portion 4 for fixing to the inside of the door 3, and a bulge portion 2 is provided at a tip of the arm rod 5. The pedestal portion 4 is provided with several through holes for the screws 6 to pass through.

Next, 7 is rotatably supported between a pedestal portion 9 fixed to the door frame 8 and a pair of bearing plates 10, 10 projecting from the upper surface of the pedestal portion 9 with a predetermined gap. The door frame side locking metal fitting which consists of the guide arm 11 of pivotal attachment substantially U shape is shown. The U-shaped guide arm 11 forming the door frame side locking fitting 7 has an opening 12 on the base end side that is large enough for the bulging portion 2 of the door side locking tool 1 to enter and exit. At the same time, the bulging portion 2 has a running groove 13 in which the bulging portion 2 can slide, and the bulging portion 2 of the door-side locking metal fitting 1 that has entered the running groove 13 of the guide arm 11 from the opening 12 is the door 3 It slides in the running groove 13 in accordance with the opening degree of and is locked at the deepest part of the U shape (Fig. 3). The pedestal portion 9 forming the door frame side locking metal fitting 7 is provided with some through holes 15 for passing the screws 14.

Therefore, if the guide arm 11 of the door frame side locking metal fitting 7 is always tilted toward the door side locking metal fitting 1 side as shown in FIG. 4, when the door 3 is opened, the door side locking metal fitting 1 is opened. The bulging part 2 slides in the running groove 13 of the guide arm 11 and becomes the state shown in FIG. 3, which can prevent unauthorized intrusion from the outside. Is for rotating the guide arm 11 from the state of FIG. 4 and tilting it toward the door frame 8.

Therefore, in the door guard fitting having such a structure, the present invention provides the U-shaped guide arm 11 forming the door frame side locking tool 7 at a proper position on the surface near the base end which is the pivot side. The feature of the present invention is that a cushioning member 16 made of an elastic material such as rubber or felt is provided in a protruding manner. In the illustrated embodiment, the cushioning member 16 extends outwardly near the base end of the U-shaped guide arm 11. A tongue piece 17 is formed to project, and a cushioning member 16 is attached to the upper surface of the tongue piece 17 so as to project slightly above the upper surface of the guide arm 11. Even if such a tongue piece 17 is not provided, as long as it does not hinder the sliding of the bulging portion 2 projecting from the door-side locking metal fitting 1, the vicinity of the proximal end portion of the guide arm 11 will be described. Of course, the cushioning member 16 may be directly provided on the upper surface, that is, the surface portion of the guide arm 11 with which the side edge portion of the door 3 abuts when the guide arm 11 is sandwiched between the doors 3. is there. The cushioning body 16 may be made of an elastic material such as rubber or felt, and may be made of a soft synthetic resin or the like. Further, in terms of shape, any shape such as a square or rectangular shape other than the circular shape shown, or an elliptical shape may be used. Can be changed to.

In this way, the door guard fitting of the present invention has the buffer arm 16 projecting near the base end portion of the U-shaped guide arm 11 forming the door frame side fitting 7, so that the guide arm 11 is originally designed. Even if the automatic lock device is sandwiched between the doors 3 to prevent the automatic lock device from working, the cushioning body 16 comes into contact with the side edge portion of the door 3, so that the metal member is not used. The manufactured guide arm 11 eliminates the possibility of peeling off the coating film on the door 3 (FIG. 5). Needless to say, even if the buffer body 16 is provided in the vicinity of the base end portion of the guide arm 11, the original function of the door guard fitting is not hindered.
