Description

Door stopper

The present invention relates to a door stopper, and more particularly, a pedal is mounted on a lower end of a rod-shaped body supporting a door, and a tension member such as a connection band is attached between the body and the pedal to provide a simple return of the pedal and the connection band. Not only can the door be easily supported or released by a simple return action by the structure and their interaction, but also the body lifted in the released state can be easily constrained by a simple snap-lock structure using a leaf spring. Relates to a door stopper.

In general, the door stopper is a device which is mounted at the bottom of the inner wall of the door to support the door against the ground so that the door does not close by itself. As shown in FIG. 1, the door stopper is mounted at the bottom of the inner side of the door 110. An attachment plate 103 and a rod-shaped body 105 coupled to the attachment plate 103 by a pivot pin 107 so as to be rotatable vertically.

Here, the attachment plate 103 is a flat plate, a pair of pivot brackets 109 to which the pivot pin 107 is coupled protrude in the center, and are attached to the wall surface of the door 110 by screws fastened to four corners. It is fixed. The body 105 has an upper end portion 126 rotatably mounted between the pivot brackets 109 and a pad 111 in frictional contact with the ground is attached to the lower end portion thereof.

Therefore, the door stopper 101 is restrained and fixed when the body 110 is lifted upward as much as possible when the door 110 is closed, and the upper end 126 is clamped between the pivot brackets 109. When the stop 101 is held in an open state, the door 101 is supported by lowering the body 105 to be pressed to the ground through the friction pad 111 as shown in FIG. 1.

By the way, the conventional door stopper 101 as described above is to lift the door to the door release position from the door fixed position pressed on the ground as shown in FIG. Since the inner part of the body must be rolled up, it is inconvenient to use, unsanitary, and not only soils or damages the shoe or the shoe, but also lifts the body to the maximum when not in use, i.e. in the door release position. The upper end 126 of the 105 is forcibly sandwiched between the pivot brackets 109 to prevent the body 105 from returning to the ground, and the gripping force of the pivot bracket 109 forcing the body upper end 126 into the ground. If this weakens, even when an unintended external force such as shaking or kicking the door is applied to the door stopper 101, the body 105 easily descends to prevent opening and closing of the door 110. There was a problem that the inconvenience caused to use.

In order to solve the problems of the conventional door stopper as described above, a door stopper has been proposed to lift the body by using various types of elastic members such as tension, compression, and torsion springs, but such door stoppers are elastic of various springs. Since many parts are required to convert the body into the rotational force of the body, the increase of the parts not only increases the cost of the product but also increases the probability of failure due to wear, corrosion or damage of the parts. There is a problem of deterioration, and when an unintentional external force is applied to the door stopper, the body is easily lowered to prevent the inconvenience of using the door, which prevents the door from opening and closing. There was a problem that the unit price of the product is increased.

The present invention has been proposed to solve the problems of the conventional door stopper as described above, by mounting a pivot and a pedal on the lower side of the pivot engaging portion of the door stopper body, by attaching a connection band between the upper end and the pivot of the body By simplifying the rotational structure of the door stopper that lifts the body when it is finished, it reduces the number of parts required for the manufacture of the door stopper, thereby reducing the possibility of damage and malfunction due to wear or corrosion of the parts. To reduce the manufacturing cost and cost, it is possible to lower the unit cost, increase the quality, and to more stably restrain and fix the body lifted to the door release position by using the locking means of the simple structure using elastic members such as leaf springs. Its purpose is to.

Therefore, the present invention is attached to the lower end of the outer surface of the door, in order to achieve the above object, the pivot bracket protrudes on the front, the lower side of the pivot bracket is attached to the rotating plate is formed; It is made of a rod body that one end is pivotably fitted to the pivot bracket of the mounting plate, and when the rod body is pivoted downward with respect to the pivot bracket so that one end of the rod is in contact with the ground, the door stops open. A body to make it possible; It is rotatably mounted on the pivoting portion formed on the lower side of the attachment plate, the body is located in a state of being turned downward when the body is lifted upward, and when the body is turned from the upper side to the lower side, A turnout that is moved from below to above by turning; A connection band connected between the body and the pivot hole so that when the one of the body or the pivot hole is pivoted, the other one is pivoted together with the other one; A pedal attached to one side of the pivoting tool to pivot the pivoting tool in a state of being fitted into a pivoting portion formed at a lower side of the attachment plate; And a locking means for preventing the body from moving to the lower side when the door is released from the one end portion of the body moved upward, when the external force is not applied to the body.

As described above, according to the door stopper of the present invention, by connecting the body for supporting the door to the turning hole by the connecting band, when the body is lowered from the upper side to the lower side to fix the door, the friction pad in the manner of lowering the existing door stopper When you press down, and the body is in contact with the ground to lift up the door to move the door can be easily lifted by pulling down the connection band by a simple step of pedaling.

Therefore, since the ascending operation of the body can be made through the addition of a simple structure called a connection band, the number of parts required in connection with the ascending operation of the body can be greatly reduced, thus assembling, manufacturing, and The production cost of the door stopper can be lowered by reducing the overall cost of purchase.

In particular, since no spring parts such as tension, compression, or torsion springs are used in connection with the operation of the stopper, malfunctions or failures of the device due to aging, corrosion, or damage to these springs and related parts can be greatly reduced. The quality of the products related to the durability and reliability of the whole parts can be further improved.

In addition, the locking protrusion protruding from the body or the locking protrusion protruding from the pivot bracket or the mounting plate to correspond to the locking protrusion is snapped to each other by the elasticity of an elastic member such as a leaf spring, thereby lifting it to the door release position. Since the jin body can be restrained and fixed more stably and effectively, the usability of the door stopper can be greatly improved.
