【Example】

 The present invention will be described below based on embodiments shown in the drawings. 1 to 7 show a first embodiment of this invention, and FIG. 8 shows a second embodiment. The door guard of the present invention can be applied to any type of door, such as an outside door, an inside door, or a sliding door, but the door guards of the first and second embodiments are both outside doors. The example used for this is shown.

In FIGS. 1 to 3, 1 is a door frame, 11 is a digging portion provided in the door frame 1, 2 is a door, and 31 is a first base body fixed to the interior side of the door frame 1 by screws 91 or the like. , 32 are provided on the first base 31, and a rod having a bulging head 33 having a flat plate shape, a spherical shape, or any other shape at the tip, 41 is a second base fixed to the inside of the door 2 with screws 92 or the like Reference numeral 42 denotes a swingable connecting rod having a base end pivotally attached to a second base 41, which is composed of a flat plate portion and a mounting projection integrally formed with the flat base portion, with a vertical axis 45, and 43 is a connecting rod 42 normally formed in a U shape. The insertion portion located at the base end side of the receiving rod 32 corresponding to the bulging head 33 of the receiving rod 32, 44 is continuous with the insertion portion 43, and is wider than the insertion portion 43 provided along the length direction of the connecting rod 42. Shows the narrow guide slots.

In the illustrated example, the second base 41 and the connecting rod 42 attached to the door 2 side are equivalent to those of a conventional door guard. This invention is characterized by the first base 31, the receiving rod 32 attached to the door frame 1 side, and the assembly structure of both.

Contrary to the illustrated example, the first base 31, the receiving rod 32, and the door 2 are mounted inside the door 2, and the second base 41 and the connecting rod 42 are mounted inside the door frame 1, respectively. Needless to say.

Next, an essential part of this invention will be described with reference to FIGS. 1 and 4 to 7. In the present invention, the first base 31 fixed to the interior side of the door frame 1 or the door 2 is formed as a hollow housing frame.

The first base 31 of the illustrated example is composed of a hollow main body 31a, a flange portion 31b integrally provided at the mouth of the main body 31a, and a lid plate 31c, and the flange portion 31b and the lid plate 31c are finally formed. It is fixed by crimping or the like.

The hollow portion 5 of the first base 31 (housing frame) communicates with, for example, a first chamber 51 having a rectangular cross section, and a second chamber 52 having a circular cross section and arranged in parallel with the first chamber 51 and both chambers 51, 52. And an axial slit 53.

The first chamber 51 is provided with a step rod 32 a at the base end side, for example, a rod 32 having a rectangular cross section so that the rod 32 can be projected slightly loosely, and the second chamber 52 has a rod 32 a. For example, a compression spring 6 for biasing 32 in the protruding direction is attached.

Both ends of the compression spring 6 are held so as to be sandwiched between the bottom of the first base 31 and one end of a pin or other pressing piece 71 that is planted on the receiving rod 32 at substantially right angles to the axial direction thereof. The receiving rod 32 is biased outward. One end of a pressing piece 71 extending from the first chamber 51 of the hollow portion 5 to the second chamber 52 has a slit 53 penetrating therethrough.

As shown in FIG. 5, when the receiving rod 32 is pulled out from the hollow portion 5, both end portions of the pressing piece 71 contact the peripheral portion of the opening 31d of the lid plate 31c forming a part of the first base 31, as shown in FIG. It is stopped by contact.

That is, in this embodiment, the pressing piece 71 constitutes the stopper means 7 together with the lid plate 31c. The pressing piece 71 forming a part of the stopper means 7 also functions as a spring receiver, but it goes without saying that it may be separately provided.

In addition, between the first base 31 and the receiving rod 32, for example, a locking projection 81 integrally provided in the opening 31d portion of the lid plate 31c and a bulging head on the tip side of the receiving rod 32.
