  In the door stopper of Patent Document 1, the friction coefficient between the floor surface and the first surface is increased by increasing the coefficient of friction of the first surface in contact with the floor surface, but the first surface is flat. Since the first surface is in surface contact with the floor surface over a wide area, the frictional force cannot be effectively exerted, and the first surface such as rubber is formed on the entire first surface of the base. Since the surface-side member is bonded, it is expected that a bonding operation such as adhesion is required on the entire surface of the raw surface, and the processing cost of the first surface in contact with the floor surface is expected to increase.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a door stopper that can be manufactured easily, can obtain a high frictional force with a floor surface, and can securely fix a door.

  The invention of claim 1 is a door stopper comprising a seat surface provided at the bottom and in contact with the floor surface, and a door locking surface that is inclined with respect to the seat surface and is in contact with the lower end of the door. An elastic member having a larger coefficient of friction than the seat surface and having elasticity is provided in a direction intersecting with the inclination direction of the door locking surface, and the elastic member protrudes downward from the seat surface and is separated from the elastic member. The contact part which touches the said floor surface is provided in the front end side.

  According to a second aspect of the present invention, the elastic member is in contact with the floor surface substantially linearly.

  Further, the invention of claim 3 includes the door locking surface that decreases from the central portion toward one side, and the door locking surface that decreases from the central portion toward the other side, and the elastic member includes , Corresponding to the central portion, provided on the seating surface.

  According to a fourth aspect of the present invention, one side and the other side are substantially symmetrical with respect to the elastic member.

  According to the first aspect of the present invention, when the door is opened and closed so that the lower end of the door rides on the door locking surface, a vertical force that presses the seating surface against the floor surface is generated by the wedge action, and this vertical force is partially applied to the seating. By applying to the elastic member protruding from the surface, a high frictional force is obtained between the elastic member and the floor surface, and the elastic member is pressed against the floor surface, and the principle of the insulator using the elastic member as a fulcrum Thus, the contact portion on the front end side of the seating surface is pressed against the floor surface, so that the door can be securely fixed. Furthermore, since the elastic member is a direction intersecting with the inclination direction of the door locking surface and intersecting the door opening / closing direction, a high frictional force can be obtained in the door opening / closing direction.

  And, the part that generates the frictional force is mainly an elastic member provided on the seating surface, regardless of the material of the part that forms the seating surface and the door locking surface, so that the design can be elaborated and the cost / The material according to the application can be used, and the shape can be designed relatively freely.

  According to the second aspect of the present invention, when a vertical force is applied to press the seating surface against the floor surface by the lower end of the door, the elastic member that comes into contact with the substantially linear shape presses against the floor surface, and the elastic member serves as a fulcrum. According to the lever principle, the contact portion on the front end side of the seating surface is pressed against the floor surface, and a reliable fixed state is obtained.

  Moreover, according to the structure of Claim 3, one side and the other side can be selected and used, and a reliable fixed state is obtained by the elastic member provided corresponding to the said center part.

  Further, according to the configuration of the fourth aspect, since the one side and the other side are substantially symmetrical, it can be used in the same manner on either one side or the other side, and the elastic member is located in the center. Thus, the same fixed state can be obtained on either one side or the other side.

  Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the embodiments described below do not limit the contents of the present invention described in the claims of utility model registration. In addition, all the configurations described below are not necessarily essential requirements of the present invention. In each embodiment, by adopting a door stopper different from the conventional one, a door stopper having an unprecedented function is obtained, and each door stopper is described.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show a first embodiment of the present invention. As shown in the figure, the door stopper 1 has a main body 2. The main body 2 is provided with a flat seat surface 3 in contact with the floor surface 100 at the bottom thereof, and is inclined with respect to the seat surface 3 and is a door. Door locking surfaces 4 and 5 that contact the lower end 102 of 101 are provided, and these locking surfaces 4 and 5 are inclined downward from the central portion 6 of the main body 2 toward one side and the other side. The main body 2 is made of various materials such as wood, metal such as stainless steel and aluminum, or resin. The door 101 is pivotally mounted on one side so as to open and close about the one side.

  An elastic member 7 is provided at the center of the seat surface 3 in the length direction, and the elastic member 7 is made of rubber having a larger coefficient of friction than the seat surface 3 and having elasticity. An object is fixed to the seat surface 3 by bonding or the like. Specifically, a substantially semicircular groove 8 is formed in the seat surface 3 in the width direction, and the elastic member 7 is bonded and fixed to the groove 8. Is projected downward from the seating surface 3. Then, both end sides of the seat surface 3 away from the elastic member 7 are contact portions 9 and 9 that are in contact with the floor surface 100.

  In this example, the seat surface 3 and the inclined surfaces 4 and 5 form an isosceles triangle shape, and the main body 2 has one side which is the door locking surface 4 side centered on the central portion 6 and the door engagement. The other side which is the stop surface 5 forms a symmetrical shape.

  Next, a method of using the door stopper 1 will be described. One door locking surface 4 is directed in the opening / closing direction of the door 101, and the length direction of the main body 2 is matched to place the door stopper 1 on the floor surface 100. When the door 101 is opened and closed, the lower end 102 of the door 101 rides on the door locking surface 4 and a vertical force is applied to the door stopper 1 by the wedge action. Due to this vertical force, the elastic member 7 comes into pressure contact with the seat surface 3 with elastic deformation, and the abutting portion 9 away from the elastic member 7 is brought into pressure contact with the seat surface 3 with the elastic member 7 as a fulcrum. A certain fixed state can be obtained. Moreover, the door 101 can be similarly fixed using the door latching surface 5 side.

  As described above, in the case of the conventional stopper, force is required for operation such as pressing strongly until the door is fixed. However, in the door stopper of this embodiment, the door closing force is directly applied as a frictional force to the floor. Since it acts on the surface 3, it can function as a stopper only by being disposed in the gap between the door 101 and the floor surface 100.

Thus, a high frictional force is obtained between the elastic member 7 and the floor surface 3, and the elastic member 7 is connected to the floor surface 100. While set pressure can be in the principle of leverage with a fulcrum elastic member 7, it is pressed against the contact portion 9 the floor surface 100 on the distal end side of the seat surface 3 to reliably fix the door 101. Furthermore, since the elastic member 7 is in a direction intersecting with the inclination direction of the door locking surfaces 4 and 5 and intersecting with the opening / closing direction of the door 101, a high frictional force is obtained with respect to the opening / closing direction of the door 101. be able to.
