The present invention relates to an improvement of the stopper for preventing the door closing, and in particular, to prevent the closing and setting of the stopper using the stopper in the open state of the door is not simply made, even if the floor is uneven does not hinder the operation of the stopper. It is to avoid.

In general, doors such as houses or offices are set up to automatically close the door when the external force is removed while the door is open above the door.

Therefore, as a means for preventing the door from closing in the open state of the door is used to install the stopper (aka bracket) on the inner bottom of the door, a representative example of the stopper used in the above as shown in Figure 12 and 13 The stopper 40 with the rubber piece inserted thereon is rotatably installed on the 30, and the bracket 30 of the stopper 20 is fastened to the bottom of the inner side of the door in consideration of the height of the stopper 20 at the bottom. Will be used.

Therefore, as an operation for preventing the closing of the door using the stopper 20 having the above-described configuration, the stopper 40 connected to the bracket 30 is rotated downward as shown in FIG. In order to prevent the closing of the door 10 by contacting the bottom surface 50 with the rubber packing inserted into the bottom of the stop bar 40, on the contrary, the stop bar as shown in FIG. 40 is rotated upwards to separate from the floor to close the door.

At this time, the bracket 30 of the stop bar 40 as a function to prevent the downward rotation again by its own weight in the state of rotating up to the axis, the bracket 30 is installed on the inner surface of the stop bar 40 then configured As the protrusion is elastically contacted, the downward rotation is controlled unless it is pulled down by an external force.

As described above, when the stopper 20 located at the bottom of the door 10 is rotated downward or upward upward when the door 10 is opened, the user operates most of the feet without manipulating the waist by hand. Will try.

When the stop bar 40 is to be rotated downward by using the foot, the stop bar 40 is not easily caught on the bottom of the shoe, and the stop bar 40 is elastically installed by the leaf spring. It is not easy to rotate downward.

As described above, when the operation of rotating the stop bar 40 downward by foot is inconvenient to operate by hand, the bottom of the shoe in the process of squeezing the stop bar 40 downward by foot. Since the surface is in contact with the inner surface of the door 10, there was a closed end where the stopper 20 is installed is easily dirty.

By operating as described above, the stop rod 40 of the stopper 20 is rotated downward to prevent the closing of the door while the rubber piece fitted to the bottom of the stop rod 40 is grounded to the bottom, but the bottom surface 50 is uneven and is in one direction. If it was inclined to the closed position, there was a closed end that did not become a function of preventing the closing of the door depending on the position, and this phenomenon appeared more severely when the rubber pieces were worn out due to long-term use, as well as when the bottom surface 50 was even. Edo the door was slipped and closed because there was a disadvantage to replace the stop.

If you want to use the stopper 20 to stop the door closing function using the stopper 20 as described above, even if the user wants to close the door closing function between the end of the shoe between the rod 40 and the door 10 There was an inconvenience to be pushed upwards and then upwards.

Therefore, there were disadvantages such as a lot of murmurs and inconveniences in setting and closing the door closing function using the stopper.

In order to rectify this disadvantage, in constructing the stopper, it has been provided that the elevating rod is vertically elastically installed in the pipe, and the elevating rod is controlled by the operating piece configured by the push button type.

However, in the case of the stopper of the above-described configuration, as well as the elevating rod fitted in the tube is vertically installed, the elevating rod is controlled by the actuating piece composed of a push button type.

In other words, since the lifting bar is formed in parallel with the door, the stop means of the door is not perfect, and even when the door is pushed to the rear, the opening bar is controlled by the lifting bar installed vertically. It was inconvenient to use.

In addition, as a means for causing the lifting rod to be lifted and controlled by the operating piece, a locking groove is formed in the lifting bar, and the locking groove is caught by the operating piece so that the lifting is controlled. In this case, there was a closure such as the door stop operation not being performed smoothly.

The present invention not only makes it easy for anyone to operate the stopper for preventing and closing the door in order to correct the above general disadvantages, but also to ensure that the function of the stopper does not interfere with the function of the stopper even when the bottom surface is inclined in one direction. It is to provide a stopper for preventing closure.                         

In order to achieve the above object, the present invention constitutes a stopper for preventing door closing, and is partitioned into an upper cabinet and a lower cabinet by a diaphragm in the body, and the main body is installed to be inclined forward through an elliptical operating rod. Press the operating rod while the rubber piece is coupled to the lower side, and the return spring is installed on the operating rod located in the upper cabinet, and the locking mechanism on the tanger spring and the tanji spring is installed on the operating rod located in the lower cabinet. The operating rod is lowered by the required distance, and the rubber piece is in contact with the bottom surface to prevent the closing of the door, and pressing the locking operation opening, the operating rod is raised and retracted, thereby preventing the closing function of the door.

The use of the door closing preventing stop 100 of the present invention configured as described above is to be used by fastening to the bottom of the inner surface of the door 400 as shown in FIG.

That is, when the operating rod 300 elastically installed on the main body 200 of the stopper 100 is pressed, the return spring 245 is compressed and the operating rod 300 descends to allow the floor to reach the floor with ease. 200 is in contact with the bottom of the inner surface of the door 400 and then fixed to the main body 200 by using a screw or the like in the fastening hole 203 formed in the flange 204 to be used.

As described above, the operation of the stopper 100 in the state in which the door stopper stopper 100 is fixed to the bottom of the inner surface of the door 400 is as follows.

First, the door 400 is opened as necessary, and then pressing the pressing piece 310 of the operating rod 300 fitted to the main body 200 of the stopper 100 with a foot, the operating rod 300 has a top plate 201 and a diaphragm ( 210 and the lower plate 202 is guided through the through hole 211 is lowered, and the return spring 245 fitted in the upper operating chamber 220 is compressed by the stop ring 312, the lower storage room The latching operation tool 240 fitted to the 230 maintains the same state as in FIG. 8 at all times while repeating the short lifting by the contact force of the tangent spring 244 and the friction with the outer surface of the operating rod 100. .

When pressing the pressing piece 310 of the operating rod 300 as described above, the rubber piece 320 inserted into the lower end of the operating rod 300 is slightly compressed to contact the bottom surface 410, in this state operating rod When the foot is released from the pressing piece 310 of the 300, the force to restore the return spring 245 compressed by the stop ring 312 to the upper storage chamber 220 of the main body 200 is operated by the operating rod 300. While acting on the operating rod 300 is going to rise but the operating rod 300 by the operation hole 241 role of the locking operation port 240 is maintained without falling as shown in FIG.

That is, the operating rod 300 does not rise by the holding force of the return spring 245 positioned in the upper chamber 220 in the state where the operating rod 300 is lowered as shown in FIG. 5, and the rubber piece 320 is bottomed. The position is fixed in the state in contact with the surface 410 is the locking operation mechanism 240 is fitted to the outer surface of the operating rod 300 as shown in Figure 7 the shaft of the insertion groove 206 by the holding force of the tanger spring 244 And the operating hole 241 is diagonally located on the outer surface of the operating rod 300, and thus, one side lower edge 241 ′ of the operating hole 241 presses one outer surface of the operating rod 300. At the same time, since the other upper edge 241 ″ of the operating hole 241 is holding the other outer surface of the operating rod 300, the operating rod 300 is bitten by the operating hole 241 of the locking operation hole 240. It is fixed, thereby preventing the rise of the operating rod 300 by the holding force of the return spring 245.

Therefore, regardless of the height of the bottom surface 410 does not hinder the functional action of the stopper (100).

In particular, in the configuration of the stopper 100 of the present invention, the operating rod 300 fitted in the main body 200 is configured to be inclined so that the rubber piece 320 fitted to the lower end of the operating rod 300 is the bottom surface 410 In addition to the function of preventing the closing of the door 400 in contact with the contact is effectively made, if you push the door 400 to the rear as necessary, it is convenient to use.

In addition, the operating plate 211 of the upper plate 201 and the diaphragm 210 and the lower plate 202 configured in the main body 200 is composed of an oval, the operating rod 300 fitted in the operating hole 211 is also elliptical. It is configured, so that the operating rod 300 does not rotate during the lifting, so that the rubber piece 320 located at the bottom of the operating rod 300 is in contact with the bottom surface 410 to prevent the rotation of the door 400 There is no obstacle to function.

When the operating rod 300 of the stopper 100 is lowered as shown in FIG. 5 and the door 400 is to be closed again by canceling the function of the stopper 100 in a state in which the closing of the door 400 is prevented. Can be operated as follows.

That is, when the user presses the foot of the operation piece 242 of the locking operation tool 240 protruding toward the front of the main body 200 in the state as shown in Figure 5 as shown in Figure 6 the locking operation tool 240 is an insertion groove 206, that is, The tangy spring 244 is compressed while rotating the stone bar 243 downward on the shaft, and at the same time, the operating hole 241 drilled through the locking operation hole 240 is parallel to the outer surface of the operating rod 300 as shown in FIG. 8. Since the operating rod 300 does not come into contact with each other while being held, the operating rod 300 is lifted by the holding force of the return spring 245, and as shown in FIG. 5 again, the function of the stopper 100 is terminated, and thus the door 400 is closed. This is done.

At this time, ascending control of the operating rod 300 is controlled when the stop ring 312 touches the bottom surface of the top plate 201 of the main body 200, the packing 312 'located above the stop ring 312 is the operating rod When the 300 rises to act as a buffer to reduce the impact and noise.

In order to cancel the function of the stopper 100, the operation piece 242 of the locking operation 240 is operated by the user to the foot is configured to protrude forward in the lower lower portion of the main body 200, the user heel of the shoe It can be operated simply by pressing the front in the state in contact with the bottom surface 410 is very convenient to use.

In the practice of the present invention, as shown in Figure 10 can be used by installing the cam-shaped locking hole 330 at the lower end of the operating rod (300).

Even in the case described above, if the user presses the pressing piece 310 of the actuating rod 300 with his foot, the actuating rod 300 descends while the cam-shaped catching hole 330 is in contact with the bottom surface of the actuating rod 300. Even when the foot is removed from the pressing piece 310, the operating rod 300 is fixed in the above state.

At this time, while the force to close the door 400 acts to move a little in the inner direction, but the cam-shaped locking hole 330 rotates the shaft pin 332 of the bracket 331 to the axis to maintain the ground force with the bottom surface 410 Since it increases, the door 400 is more firmly supported and fixed.

If you want to cancel the closing prevention function of the door 400 in the above state, as described above by pressing the operating piece 242 of the locking operation mechanism 240 protruding on the front of the main body 200 return spring 245 Since the operating rod 300 is raised and retracted by the holding force of the door, the closing of the door is made.

As described above, in the present invention, when constructing the stopper for preventing the door from being closed, the elliptical actuating rod is inclined elastically installed on the main body, and the elevating adjustment of the actuating rod is assembled to the main body. The door closing function can be set and canceled by pressing the operating piece of the operating rod or by pressing the operating piece of the locking mechanism, so it is convenient for all ages and sexes, and even if the floor is uneven, the stopper function can be effectively performed. It is possible to provide a high quality door stopper.
