FIG. 1 is a perspective view schematically showing an apparatus for preventing automatic door closing according to an embodiment of the present invention, and FIG. 2 is a view illustrating a holder of the automatic closing prevention apparatus shown in FIG.

Referring to FIGS. 1 and 2, an apparatus 100 for preventing automatic closing of a sliding door according to an embodiment of the present invention includes a fixing portion 200 and a holder portion 300.

The fixing part 200 is fixed to the wall 20 which collides with the hinged door 10 when the hinged door 10 is opened. A cushioning member 30 is mounted on the hinged door 10 to prevent the handle or the corner portion from directly bumping against the wall 20 during the opening of the hinged door 10. [ The cushioning member (30) includes a supporting rod projecting higher than the handle and a cushioning ball (34) providing a cushioning characteristic to an end of the supporting rod. Here, the cushioning ball 34 may be made of a rubber material having excellent buffering ability against price.

Specifically, the fixing part 200 is fixed at a position where the cushioning member 30 of the wall 20 is contacted in the process of opening the hinged door 10. The fixing portion 200 may be formed of a suitable fixing means depending on the material of the wall 20. [ For example, when the wall 20 is made of cement, anchor piece or concrete nail may be used for the fixing part 200. For wood, a drill piece or a wooden peg for wood may be used. Alternatively, the fixing part 200 may be integrally formed with the wall 20 during the initial manufacture of the wall 20.

The holder part 300 is installed in the fixing part 200. The holder 300 instantaneously holds the cushioning ball 34 by elasticity when the cushioning member 30 hits the fixing unit 200. For this, the holder 300 includes a holding bar 310, a guide 320, and an elastic part 330.

The holding bars 310 are spaced apart from each other such that a space for inserting the buffer balls 34 is formed between the holding bars 310. At this time, the surface of each of the holding bars 310 to be contacted when the cushioning balls 34 are inserted may have a curved surface structure to smoothly guide the insertion of the holding bars 310. Each of the holding bars 310 may have a round bar shape. The holding bars 310 may have substantially the same shape, since the two holding bars 310 play the same role.

The guide part 320 is installed between the holding bars 310 and the fixing part 200. The guide part 320 guides the movement of the cushioning ball 34 so that the cushioning ball 34 is inserted into the space between the holding bars 310 so that the cushioning space can be opened or broken. The guide part 320 may be connected to the fixing part 200 through a hinge structure to smoothly guide the movement of the holding bars 310.

2, the guide part 320 may have a structure in which the holding bars 310 and the fixing part 200 are simply connected to each other in the form of a plate. However, the outer shape of the holding bars 310 may be wrapped And may have a fan shape having coupling holes into which both ends of the holding bars 310 can be inserted.

The elastic portion 330 is mounted on the guide portion 320. The elastic part 330 is installed to provide the holding bars 310 with elasticity so that the holding bars 310 are broken. The elastic part 330 may have a structure in which an elastic body such as a rubber band or a spring is connected between the guide parts 320 connected to the respective holding bars 310.

The cushioning member 30 mounted on the hinged door 10 may be inserted into the wall 20 so as to prevent the handle or the corner portion from directly bumping against the wall 20 when the hinging door 10 is opened. By temporarily holding the cushioning ball 34 coupled to the end of the cushioning member 30 through the holder 300 fixed to the fixing part 200 through the elasticity, It is possible to easily prevent the hinged door 10 from being banged by the wind from the outside.

Thereby, the user can use the hinged door 10 more safely as the possibility of psychological surprise or physical damage is essentially eliminated by the hinged door 10.

3 is a schematic view of an apparatus for preventing automatic closing of a sliding door according to another embodiment of the present invention.

1 and 2, except for the shape of the fixing portion, the structure of the holding bars, and the characteristics of the buffering member added thereto, the detailed description thereof will be omitted.

Referring to FIG. 3, the fixing part 500 of the automatic door closure prevention device 400 according to another embodiment of the present invention has a housing structure. Thus, the holder unit 600 is built in the fixing unit 500 of the housing structure. Thus, if the fixing part 500 has a housing structure, a very neat design can be realized.

1) of the cushioning member 30 (see FIG. 1) of the cushioning member 30 (see FIG. 1) is inserted into the fixing part 500. The insertion hole 510, in which the holding bars 610 of the holder part 600 are partially exposed, Respectively. Specifically, the holding bars 610 of the holder unit 600 built in the fixing unit 500 having the housing structure may be partially exposed to the outside from the insertion hole 510. Here, the insertion hole 510 may be structurally and stably formed at the center of the fixing part 500.

The holding bars 610 of the holder 600 may be formed to be narrower in the direction of one side. In this case, the cushioning ball (34 in FIG. 1) is inserted into the space between the holding bars 610 by the narrowing shape in the process of being inserted between the holding bars 610, have.

FIG. 4 is a schematic perspective view of a device for preventing automatic door closing according to another embodiment of the present invention, and FIG. 5 is a sectional view of a holding block of the automatic closing device shown in FIG.

Referring to FIGS. 4 and 5, an apparatus 700 for preventing automatic closing of a sliding door according to another embodiment of the present invention includes a holding block 800 and at least one ball plunger 900.

The holding block 800 may be secured to the wall 20 as an integral structure with the securing portion (200 of FIG. 1) in the embodiment with reference to FIGS. The holding block 800 has an insertion hole 810 in which a cushioning ball 34 of a cushioning member 30 mounted on the hinged door 10 is inserted. Accordingly, the holding block 800 may have a height higher than the diameter of the cushioning ball 34 so that the cushioning ball 34 can be completely inserted.

The ball plunger 900 is formed inside the insertion hole 810 of the holding block 800. The ball plunger 900 is provided with a ball 910 protruding partly toward the insertion hole 810 and a ball 910 provided inside the ball 910 to provide elasticity to expose the ball 910 in the direction of the insertion hole 810 And a spring 920 which is a spring.

Thus, the cushioning ball 34 can be easily held by the elasticity of the ball plunger 900 while being inserted into the insertion hole 810 in the process of opening the hinged door 10. At this time, a plurality of the ball plungers 900 are formed at predetermined intervals in the inside of the insertion holes 810 to hold the buffer balls 34 more stably. Since the number of the ball plungers 900 is substantially correlated with the force to be inserted into the buffer balls 34 and the force to hold the ball balls, the number of the ball plungers 900 may vary depending on the installation condition of the hinged door 10, . ≪ / RTI >

As the cushioning ball 34 is held through the holding block 800 having the insertion hole 810 in which the ball plunger 900 is formed, it is possible to easily prevent the hinged door 10 from being closed In addition to being clean, due to the appearance of one block type, there is an additional advantage that the failure rate is relatively small even when using for a long time.

While the present invention has been described in connection with what is presently considered to be practical and exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
