Summary of the Invention

Problems to be Solved by the Invention

[0004] The present invention is a door stopper that solves such problems and is simplified. The door stopper of the present invention only requires processing of the door and does not require processing of the floor material. Also there is freedom in the angle at which the door can be opened and held, and it can be held at any location.

Means for Solving the Problems

[0005] The door stopper according to the present invention is capable of holding a door in an open state, and the door stopper includes a fixing portion 1 attached below the door and a movable portion 2 that appropriately contacts the floor surface. The movable portion 2 includes a holder 5 made of a material having a high coefficient of friction, and an elastic body that restores the holder 5 from a position contacting the floor surface to a position away from the floor surface. The holder 5 is in contact with the floor surface to hold the door in an open position, and the holder 5 is moved away from the floor surface by the return of the elastic body, thereby releasing the door from being held in the open position and allowing it to be opened and closed. In the present invention, it is preferable that the holder 5 is made of soft polyvinyl chloride or rubber.

[0006] Furthermore, in the present invention, it is preferable that the movable part 2 comprises a movable plate 7 and a mounting member for attaching the movable plate 7 to the fixed part 1, the mounting member is provided with the elastic body, and the holder 5 is attached to the tip of the movable plate 7. Furthermore, in the present invention, it is preferable that the elastic body is a spring 4, the mounting member comprises the spring 4 and a pin 3, an insertion hole is provided on the rear end side of the movable plate 7, and the movable part 2 is attached to the fixed part 1 by inserting the pin 3 with the spring 4 attached into the insertion hole and also into an insertion hole provided in the fixed part 1.

[0007] The door stopper of the present invention only requires attachment to the door and does not require any floorboard processing. The movable part 2 of the door stopper is normally located above the bottom edge of the door due to an elastic body (coil spring 4). A holder 5 (made of soft polyvinyl chloride, etc.) is attached to the tip of the movable part 2. When the movable part 2 is pushed with a foot or the like at the position where the door is to be stopped, the tip of the holder 5 is inserted between the door and the floorboard. If the knob is then pulled slightly in the closing direction, the door will stop firmly in place. The holder 5 (for example, soft PVC) has a high coefficient of friction, so it maintains a stable stationary state. Also, when the knob is pushed in the opening direction of the door, the movable part 2 springs up due to the restoring force of the elastic body (coil spring 4), releasing the door from its stationary state and allowing it to be opened and closed freely. [Effects of the Invention]

[0008] The door stopper according to the present invention has an inexpensive and simple structure, and can maintain a stable stationary state. [Brief explanation of the drawing]

[0009] [Figure 1] (a) is a perspective view of a door stopper according to an embodiment of the present invention, and (b) is a perspective view showing the door stopper attached to a door. [Figure 2] This is an exploded perspective view of a door stopper according to an embodiment of the present invention. [Figure 3] (b) is a perspective view showing a door being held in place using a door stopper according to an embodiment of the present invention, and (a) is a perspective view showing the state of the door stopper at that time. [Figure 4] This diagram illustrates the assembly process for the movable part 2 of the door stopper. [Modes for carrying out the invention]

[0010] Figure 1(a) is a perspective view of a door stopper according to an embodiment of the present invention, and Figure 1(b) shows the door stopper of this embodiment attached to a door. Figure 2 is an exploded perspective view of the door stopper of this embodiment. Figure 4 shows the assembly process of the movable part 2 in the door stopper. As shown in Figures 1 and 2, the door stopper 11 comprises a fixed part 1, a movable part 2, a pin 3, a coil spring 4, and a holder 5.

[0011] Figure 3(b) is a perspective view showing the door stopped in the open position by the door stopper 11 of the present invention, and Figure 3(a) is a perspective view showing the state of the door stopper 11 at that time. This embodiment is a door stopper 11 that can hold the door 12 in an open position. The door stopper 11 is attached near the lower end of the closing side of the door 12. The door stopper 11 consists of a fixed part 1 and a movable part 2, with the fixed part 1 being fixed to the door 12. As shown in Figure 4, the movable part 2 has a movable plate 7, a holder 5 provided at its tip, and a mounting part provided at its rear end. The movable part 2 is attached to the fixed part 1 by the mounting part, and the return of the elastic body (spring 4) provided at the mounting part causes the holder 5 at the tip of the movable plate 7 to be positioned upward (away from the floor) (see Figure 1). In use, when the door 12 is opened, the movable plate 7 of the door stopper 11 is operated with the foot to bring the holder 5 into contact with the floor surface. The holder 5 is made of a soft polyvinyl chloride material with a high coefficient of friction, so the friction between the holder 5 and the floor surface holds the door 12 in its open position.

[0012] Specifically, as can be seen in Figure 3, the tip of the holder 5 of the movable part 2 is inserted into the gap between the door 12 and the floorboard, keeping the door 12 stationary. The door stopper 11 of the present invention can remain stationary at any position when the door 12 is opened. To remove it, pushing the door 12 in the opening direction causes the tip of the holder 5, which was inserted into the gap between the door 12 and the floorboard, to detach from the gap. Then, the elastic body (spring 4) returns to its original position, causing the tip of the movable plate 7 to rise, the holder 5 to separate from the floor surface, and the door 12 to be opened and closed. This door stopper 11 only needs to be attached to the door 12, and no floor material processing or additional parts for the floor material are required.

[0013] Thus, the door stopper 11 of the present invention is installed only on the door 12, and no work on the floorboard is required. The movable part 2 of the door stopper 11 is normally positioned above the bottom edge of the door 12 by a coil spring 4, and a holder 5 (made of soft polyvinyl chloride) is attached to the tip of the movable part 2. When the movable part 2 is pushed with the foot at the position where the door 12 is opened and stopped, the bottom tip of the holder 5 is inserted between the door 12 and the floorboard. At that time, if the knob is pulled slightly towards the front to close it, the door 12 will come to a stop in place. Because the holder 5 (soft PVC) has a high coefficient of friction, it maintains a stable stationary state. Also, when the knob is pushed in the direction to open the door 12, the movable part 2 instantly jumps up, and the door 12 is normally released. The stopper of the present invention is always in a jumped-up state by the coil spring 4 in the movable part 2 and is located above the bottom edge of the door 12, and a holder 5 (soft vinyl chloride) is attached to the tip of the movable part 2. [[ID=H1]] [[ID=H2]]

[0014] [[ID=H3]] As shown in Fig. 1(a) etc., the holder 5 has a U-shaped cross section, the upper piece 5a thereof is adhered to the movable plate 7, and the U-shaped lower piece 5b is free. Also, this lower piece 5b becomes thinner toward the tip in a tapered shape. [[ID=H5]] The tip part of the holder 5 (the tip side of the U-shaped lower piece 5b) at the tip part of the movable part 2 is inserted into the gap between the door 12 and the floor board. When the door knob is pulled forward, this inserted state becomes more secure, and the door 12 maintains a stationary state. The holder 5 (soft vinyl chloride) is soft and has a high coefficient of friction, so it maintains a higher stationary state. [[ID=H7]] [[ID=H8]]

[0015] [[ID=H9]] Also, the size of the gap between the door 12 and the floor board can be adjusted at the mounting position in the vertical length of the screw hole ⑥ of the fixing part 1. [[ID=H11]] Also, when the door knob is pushed slightly in the opening direction, the movable part 2 instantly jumps up by the restoring force of the coil spring 4, and the door 12 is released to a free state. [[ID=H13]] The door stopper 11 of the present invention is only attached to the door 12, and there is no work on the floor surface. The movable part 2 of the door stopper 11 is always in a jumped-up state by the coil spring 4 and is located above the bottom edge of the door. Since a holder 5 (soft vinyl chloride) is attached to the tip of the movable part 2, when the movable part 2 is pressed with the foot at the position where the door 12 is desired to be opened, the holder 5 is inserted into the gap of the floor material. When the door knob is pulled slightly in the direction to close the door 12, the holder 5 adheres to the floor material and maintains a stationary state. Also, when the door knob is pushed in the opening direction, the movable part 2 jumps up and the door 12 becomes a free state. [[ID=H15]] [[ID=H16]]

[0016] [[ID=H17]] The door stopper according to the present invention is not limited to the above embodiments. For example, in the above embodiments, an example using the coil spring 4 as an elastic body is shown, but it is not limited thereto, and it may be configured using a leaf spring or rubber as the elastic body. Further, although soft polyvinyl chloride (soft vinyl chloride) is cited as the material of the holder 5, it is not limited thereto, and other materials showing a high coefficient of friction such as rubber can be used.
