Description

  The present invention relates to a door stopper. Specifically, the present invention relates to a door stopper that can be fixed and released only by a door while the door stopper is placed on the floor.

  Conventionally, a hard wedge-shaped door stopper is generally used. Although many are made of rubber, it is basically hard and does not deform. Even if it is deformed, the amount of deformation is very small. The usage is to insert a wedge-shaped point into the gap between the lower surface of the door and the floor surface to prevent the door from going toward the wedge-shaped mountain (the taller one). By utilizing the wedge shape physically, the wedge shape cannot be used more than a certain amount in a narrow gap.

The door stopper is no longer needed, and every time you remove it, you had to squat down and remove it by hand.

  A door that cuts into the gap between the lower surface of the door and the floor and prevents the door from moving in a wedge-shaped point by frictional resistance between the lower surface of the door and the floor and the door stopper, and fixes the door at an arbitrary opening angle. There was no stopper. Moreover, there was nothing based on deformation or frictional resistance.

  Even when the door stopper was inserted into the lower surface of the door, there was nothing that simply placed it on the floor and pressed the door. Some of the trapezoidal trapezoidal trapezoidal or substantially polygonal frustum trapezoidal shapes were close to it, but had to be pressed by the toes of the foot, and not the wedge-shaped ones. Also, when releasing the fixed door, there was no door stopper that would allow the door to come off if it was pulled strongly in the closing direction. In order to remove the substantially truncated cone shape or the substantially polygonal truncated cone shape, it must be held by a toe. The substantially frustum shape or the substantially polygonal frustum shape is placed on the same side as the wedge shape.

  The thing of patent document 1 is a door pressing device which attached the leaf | plate spring on the support stand which gave the height similar to the wedge shape, and uses it by making it bite into the clearance gap between a door lower surface and a floor surface. The mechanism for holding the door is not based on the frictional resistance between the lower surface of the door and the leaf spring, but utilizes the property that the lower surface of the door does not advance in the higher direction of the leaf spring as in the wedge shape. The surface of the leaf spring is not subjected to anti-slip treatment.

  The thing of patent document 2 is a door fixing tool which comprised the wedge-shaped slope by hard rubber and comprised the bottom face with soft rubber. The inclined surface in contact with the lower surface of the door is integrally formed with a hard rubber having a smooth surface and high strength, and the bottom surface in contact with the floor surface is integrally formed with a soft rubber having a large frictional resistance. The usage is to fix the door at an arbitrary opening angle by using the property that the door does not advance in the high direction of the wedge shape by biting into the gap between the lower surface of the door and the floor surface. Soft rubber on the bottom has a large frictional resistance and does not move against the floor. The hard rubber on the slope will safely absorb the impact with the lower surface of the door and will not damage both sides. Hard rubber on the slope does not have a large frictional resistance and does not deform.

  The thing of patent document 3 is a wedge-shaped door stopper which made the material the plastic of the material similar to rubber | gum or rubber | gum. The usage is the same as that of Patent Document 2. If the material is made of rubber or a plastic material similar to rubber, the door stopper does not slide tightly on the floor and stops at a desired location. In the text, it is written that the rubber is closely attached to the floor and does not slip, and there is no description about deformation. In the drawing, the rubber on the slope is swollen round like a bump when pushed by the corner of the lower end of the door. Rubber is not in surface contact with the lower surface of the door. The corner at the bottom of the door is just in line contact. It is considered that there is no recognition of the fact that the soft rubber is deformed to increase the contact area with the lower surface of the door and the frictional resistance between the rubber and the lower surface of the door.

  The thing of patent document 4 is a wedge-shaped door stopper which formed the wedge-shaped main body with the member which has a softness | flexibility, and provided several through-holes in the triangular plane part facing in parallel. The through holes are provided so as to gradually increase from the acute angle portion of the wedge-shaped triangle toward the opposite side. The usage is the same as that of Patent Document 2. Since there is a through hole, flexibility is increased near the through hole, and the door is maintained at an arbitrary position by the restoring force of the material characteristics. The mechanism for maintaining the door is not based on the frictional resistance between the lower surface of the door and the slope, but utilizes the property that the lower surface of the door does not advance in a wedge-shaped high direction. The surface of the slope is not slip-proofed. The purpose of the flexibility is for plastic deformation and durability of the rigid material of the prior art, and there is no description about an increase in contact area with the lower surface of the door due to deformation.

  The thing of patent document 5 is a door stopper in which the friction coefficient of the slope of a wedge-shaped main body is smaller than the friction coefficient of a bottom face. The usage is the same as that of Patent Document 2. Since the friction coefficient of the bottom surface is larger than that of the slope, when the lower end of the door hits the slope of the door stopper, the lower end of the door slides slightly on the slope, the door stopper is pressed against the floor, and the bottom It does not move. Since the friction coefficient of the bottom surface is large, the door stopper is held in that place without sliding against the floor surface. The mechanism for holding the door is not based on the frictional resistance between the lower surface of the door and the slope, but utilizes the property that the lower surface of the door does not advance in a wedge-shaped high direction.

  The thing of patent document 6 is the door stopper which enclosed the weight for lowering a gravity center in the hollow sphere made from the elastic material, and made it hard to roll. As the weight, a liquid such as water, a metal or stone piece, sand or the like is used. To use, place the door stopper on the floor surface where you want to open the door, and when the lower end of the door hits, the spherical door stopper deforms and rotates and enters between the door and the floor surface, Push the door back by elasticity to hold the door. When pulling strongly toward the door closing, the sphere rotates under the door, slips under the door and releases. The door is held by the rebound resilience of the elastic body and not by the frictional resistance.

  The thing of patent document 7 is a substantially frustoconical shape with a trapezoidal cross section, or a substantially polygonal frustum shape, and has a bottom face, and the inside is a door stopper shaped like a hollow dish. It consists of a thin plate-like upper surface and a peripheral inclined portion, and the lower end of the peripheral inclined portion is in contact with the floor surface. The material is rubber or soft plastic. The door stopper can be inserted and removed with just the toe of the foot, and there is no need to squat when attaching and detaching. Usage is basically the same as that of Patent Document 2, and an acute angle portion having a trapezoidal cross section is inserted into the gap between the lower surface of the door and the floor surface. At that time, the door stopper may be placed at the target position on the floor surface, the door stopper may be pressed with a toe, and the lower end of the door may be pressed. When removing the door stopper, the door stopper may be pressed with a toe and the door may be pulled in the direction of the acute angle portion of the trapezoidal cross section. The mechanism for holding the door is the same as that of the wedge shape, because the lower end of the door that hits the inclined portion cannot advance to the higher portion of the inclined portion. There is no anti-slip means in the inclined part, and it is not due to frictional resistance.

  In summer, the door must be closed and opened each time the air conditioner is turned on and off. When the door is open, the door closes with the wind, so you must attach or remove the door stopper each time. There are many other things that you want to insert and remove door stoppers. It ’s really cumbersome to have to do it by hand every time you put it in and out. Also, since the door stopper is placed on the side in the direction of closing the door, the door stopper must be removed to close the door.

  It is convenient to have a door stopper that can fix and release the door while the door stopper is placed on the floor surface, that is, without being pressed by the toes of the foot. In order to fix and release the door with only the door, the door stopper must be placed on the side opposite to the wedge-shaped door stopper of the prior art. That is, the lower surface of the door is pressed or removed from the acute angle portion.

  The problem to be solved by the present invention is to solve these problems and provide a door stopper capable of fixing and releasing the door only by the door even when the door stopper is placed on the floor surface.

  The door stopper which can be fixed / released only by the door according to claim 1 has an inclined surface 12 and a bottom surface 11, and an anti-slip means 121 and an anti-slip means 111 are respectively provided on the inclined surface 12 and the bottom surface 11 of the main body 10 made of a flexible body. It is provided.

The main body 10 having the inclined surface 12 and the bottom surface 11 means that the main body 10 is not limited to the wedge shape, but may have other shapes as long as the inclined surface 12 and the bottom surface 11 are provided.

  The inclined surface 12 does not necessarily have to be a flat surface and may be a curved surface. A concave surface or a convex surface may be used, or a repetitive curved surface having an uneven surface may be used. It may be one in which fine unevenness is repeated to increase the frictional resistance. The cross-sectional shape of the fine irregularities may be a W-shaped corner-pointed shape, a rounded wave shape with a gentle curve, or a square-shaped shape in which the U-shape is inverted and repeated. It may be not only perpendicular to the longitudinal direction but also parallel. The planar projection shape is not limited to a rectangle, and may be another polygon or another shape including a curve.

  Since the bottom surface 11 is in contact with the floor surface 4, a flat surface is preferable. Not only the smooth surface but also a fine unevenness or small protrusion provided to increase the frictional resistance. The shape is not limited to a rectangle, but may be other shapes. The area may be different from the area of the slope 11. It depends on the shape of the main body 10.

  The flexible body only needs to be deformable by being pushed, and may be solid (solid) or foam. Usually, a foam is good in terms of weight reduction and cost. It is better to have some resilience. The material may be rubber or plastic, or other materials such as felts and springs. What is easy to bite into the clearance gap between the lower surface of the door 2 and the floor surface 4 is good. As a result, the contact area is increased, the lower surface of the door is pushed up by the resilience of the flexible body, and the friction resistance with the lower surface of the door and the floor surface 4 is increased to fix the door 2.

    The degree of flexibility is wide, and it can be very hard, such as urethane foam for dishwashing in the kitchen or something that can not be used in practice, but it can be very soft, such as food konjac. Examples of solid and extremely soft materials such as konjac include a sol type vinyl chloride resin blended with a large amount of plasticizer, and a special synthetic rubber for low hardness. As for the harder one, the harder EVA foam or the harder one of two types sold as sponges for bathing shoes and mats for bathrooms may be used. You can also use the softer polyethylene foam of the bathroom mat. Solids include soft rubbers with low hardness, and those obtained by adjusting the plasticizer amount of the sol-type vinyl chloride resin blended with a plasticizer to adjust the softness to a higher level. Even if the main body 10 is hard and hardly deformed, such as a commercially available door stopper, if the attached anti-slip material is deformed by a foam, the flexible body is considerably hard because the door 2 is fixed. Even things can be used.

  An elastic body such as rubber or a soft plastic such as vinyl chloride resin may be used to make a frame structure to make a flexible body. Adjust flexibility and elasticity with material, thickness, structure, etc.

  The angle formed by the inclined surface 12 and the bottom surface 11 is not easily limited because it is related to the hardness (softness) of the flexible body and the anti-slip force. If it is a soft material, it can bite into the gap between the lower surface of the door and the floor even if the angle is large, but if it is a hard material, it cannot enter unless the angle is reduced. It is also related to the rebound resilience of flexible bodies. If the rebound resilience is weak, the force that pushes the lower surface of the door or the floor surface is weak and the frictional resistance is also weak, so the force for fixing the door is insufficient. The anti-slip force of the anti-slip material is also related. If the anti-slip force is strong, it can be fixed even if the contact area is small. The angle should be determined by trial and error including the length of the door stopper in the longitudinal direction.

  The angle is important. Urethane foam for kitchen dishwashing is soft, so when a prototype with an angle of 20 degrees was made as a prototype, it slips on the floor surface 4 and does not bite into the gap between the lower surface of the door and the floor surface 4. Considering lightness as one of the factors, a 2 mm thick zinc-coated iron plate was attached between the bottom surface 11 and the anti-slip material, but sliding did not stop. We tried to increase the weight by doubling the width of the galvanized iron sheet. However, when the angle was set to 12 degrees, which is substantially the same as 14 degrees (one example) of a commercial product, no slipping occurred, and the door 2 was fixed by biting under the lower surface of the door. It turns out that weight is irrelevant. The urethane foam for dishwashing is weak in rebound resilience, but can fix the door 2. It depends on the performance of the anti-slip material. It slips with a small anti-slip force.

  The anti-slip means increases the frictional resistance with the lower surface of the door or the floor surface 4 and makes it difficult to slip. Examples of the anti-slip means include an anti-slip material made of a material having a high frictional resistance, fine irregularities on the surface that increase the frictional resistance, protrusions, a small suction cup, and a door lower surface holding piece 123 that mechanically holds the lower surface of the door. According to the present invention, the lower surface of the door and the door stopper 1 and the door stopper 1 and the floor surface 4 are not moved by the frictional resistance, and as a result, the door lower surface and the floor surface 4 are fixed. When the frictional resistance of the main body 10 is large, the antislip material attachment may be omitted.

  Examples of the anti-slip material include low hardness (soft) rubber, rubber foam, soft plastic such as vinyl chloride and plastic blended with vinyl chloride, and foam of these plastics. Others may be used as long as they have a high frictional resistance and are difficult to slip with respect to the lower surface of the door 2 or the floor surface 4. The surface state may be smooth, repeated with fine irregularities in the form of grooves or dots (including rubber sheets with small protrusions that are attached to table tennis rackets), those with holes, mesh-like ones, The thing etc. which arranged the small suction cup may be used. Commercially available mesh-like vinyl chloride foam or sheet-like anti-slip material may be used.

  The anti-slip property of rubber and rubber foam varies depending on the composition (formulation). Various tests were conducted on commercially available sheet-like rubber foams, but the difference in slip resistance was large. The closed-cell rubber foam for wetsuits was the most slip-resistant among the tests. When the same anti-slip material is used for the bottom surface 11 and the slope 12, it is better to adopt a material having good anti-slip properties. This is because the bottom surface 11 is easily slidable with respect to the floor surface 4 because the slope 12 is difficult to slide.

  Further, as the anti-slip means, a door lower surface may be mechanically held such as a door lower surface holding piece 123 formed of an elastic body such as rubber or soft plastic and formed into a thin plate shape or a triangular shape having a long and narrow cross section. The door lower surface holding piece 123 may be the other one as long as the root is bent or restored by an elastic body.

  The door stopper 1 that can be fixed and released only by the door means that when the door stopper 1 is attached and detached, it does not have to be crouched each time and placed or removed. If pressed, the door 2 is fixed, and if the door 2 is pulled strongly in the direction of removing the fixed door 2, that is, the direction of releasing the fixing, the door 2 is released. The term “fixed” means that the door 2 does not move with the force of the wind blown by frictional resistance, but holds the door 2 to the extent that it can be removed by pulling it with your hand. . The release means removing the door 2 from the fixed state. “Can be fixed / released” means that both fixing and releasing are possible.

  The door stopper which can be fixed / released only by the door according to claim 2 is such that the anti-slip force of the anti-slip means 111 provided on the bottom surface 11 is greater than the anti-slip force of the anti-slip means 121 provided on the slope 12. It is a door stopper that can be fixed and released only by the door.

  The fact that the anti-slip force of the anti-slip means 111 provided on the bottom surface 11 is greater than the anti-slip force of the anti-slip means 121 provided on the slope 12 means that the bottom surface 11 is less slippery. Anti-slip force means the ability to express difficulty in slipping, and the greater the slip resistance, the less slippery. When the lower surface of the door is pressed against the door stopper 1, the bottom surface 11 is less slippery. Therefore, the door stopper 1 does not move, the door lower surface slightly slides on the slope 12, and the main body 10 is deformed by a flexible body. The lower surface is shaped like a little over the slope 12. As a result, the door stopper 1 is slightly cut into the gap between the lower surface of the door and the floor surface 4 and fixes the door 2. It is a feature of the invention of claim 2 that the lower surface of the door easily rides on the inclined surface 12 of the door stopper 1, the contact area between the lower surface of the door and the inclined surface 12 is increased, and the adhesion between the both surfaces is reinforced.

  The technical idea that the anti-slip force of the anti-slip means 111 provided on the bottom surface 11 is greater than the anti-slip force of the anti-slip means 121 provided on the slope 12 is described in Patent Document 5. The thing of patent document 5 is a hard main body, and does not deform | transform. In the present invention, the main body 10 is a flexible body and is deformed when the lower surface of the door is pressed. The large anti-slip force of the bottom surface 11 not only prevents the bottom surface 11 from moving with respect to the floor surface 4, but also facilitates the lower surface of the door to ride on the slope 12 and helps to increase the contact area. The purpose of making the anti-slip force of the bottom surface greater than the anti-slip force of the slope is that the door stopper does not move relative to the floor surface in the invention of Patent Document 5, whereas in the invention of claim 2, the door stopper 1 is The purpose is not only to prevent the floor 4 from moving but also to increase the contact area because the lower surface of the door easily rides on the slope 12.

  The anti-slip force represents the difficulty of slipping on the contacting surface. It is equivalent to frictional resistance. A thing with a large friction coefficient has a large frictional resistance. Measurement of anti-slip force is difficult but easy to compare. Apply different anti-slip materials to the slope 12 and the bottom surface 11 of the door stopper 1 and use them as door stoppers. The anti-slip force of the other anti-slip material is large. Conversely, if the bottom surface 11 moves, the anti-slip material attached to the slope 12 has a greater anti-slip force.

  The door stopper according to claim 3, wherein the door stopper that can be fixed / released only by the door is a door lower surface holding piece 123 made of an elastic body in which anti-slip means provided on the slope 12 is arranged at a constant interval. It is a door stopper that can be fixed / released by itself.

  The constant interval means a fixed interval that is slightly thicker than the thickness of the door 2.

  As described in [0029], the door lower surface holding piece 123 is a door stopper that can be fixed / released only by the door according to claim 1. The lower surface of the door is held. The door lower surface holding piece 123 is an elastic body only at the base, and the front may be a rigid body as long as it can be bent and restored.

  The door stopper which can be fixed / released only by the door according to claim 4 is a door stopper which can be fixed / released only by the door, in which the main body 1 having a larger area on the bottom surface 11 than the inclined surface 12 is composed of a non-slip flexible body. is there. The anti-slip flexible body is a flexible body having an anti-slip force. The constitution by itself means that it is constituted by itself without using other materials. Any shape may be used as long as the bottom surface has a larger area than the slope. It is assumed that the main body 10 is also configured as a single unit by, for example, a wedge-shaped slope portion and a plate-shaped bottom surface portion separately prepared with the same material and configured by bonding.

  The door stopper which can be fixed / released only by the door according to claim 1 is that if the door stopper 1 is placed on the floor surface 4 at an arbitrary position where the door 2 is desired to be opened, 2 can be fixed, and can be released simply by pulling the fixed door 2 strongly.

  The door stopper that can be fixed / released only by the door according to claim 2 is assured by simply pressing the door 2 if the door stopper 1 is placed on the floor surface 4 at any position where the door 2 is desired to be opened. The door 2 can be fixed to the door, and the fixed door 2 can be released simply by pulling the door 2 strongly.

  The door stopper that can be fixed / released only by the door according to claim 3 can be fixed simply by pressing the door 2 if the door stopper is placed on the floor surface 4 at any position where the door 2 is to be opened. There is an effect that it can be released simply by pulling the fixed door 2 strongly.

  The door stopper which can be fixed / released only by the door according to claim 4 can be fixed simply by pressing the door 2 if the door stopper is placed on the floor surface 4 at an arbitrary position where the door 2 is to be opened. In addition to the effect that the fixed door 2 can be released simply by pulling it firmly, the slope 12 and the bottom surface 11 are well understood, the stability is good, and the main body 1 can be made of one material.

  The door can be placed on the floor where you want it to open, and the purpose of obtaining a door stopper that can be fixed or released by simply pressing the door or pulling it firmly is a flexible body with a slope and bottom. This was realized by providing anti-slip means on the slope and bottom of the main body.

  A door stopper that can be fixed and released only by the door of the first embodiment will be described with reference to FIG. 1A is a perspective view showing a use state of a door stopper 1 (hereinafter simply abbreviated as “door stopper 1”) that can be fixed / released only by the door of the first embodiment, and a circle shows an enlarged view showing the use state. ) Is a perspective view showing the main body 10, and (C) is a perspective view showing the door stopper 1. FIG.

  As shown in (A), in a direction opposite to the door stopper of the prior art, a wedge-shaped mountain (the higher one) is placed on the floor surface 4 toward the wall surface 3 and the door 2 is pressed. The lower surface of the door rides on the anti-slip material 121 on the slope 12 of the door stopper 1 and is fixed by frictional resistance. The main body 10 is deformed due to the flexible body, and has a shape that bites into the gap between the door lower surface and the floor surface 4. The position where the door stopper 1 is placed may be any place where the door is desired to be opened. When releasing the fixed door 2, the door 2 may be pulled strongly in the closing direction.

  (B) shows the main body 10 of the first embodiment, which is a wedge-shaped solid flexible body.

  The door stopper 1 of Example 1 shown to (C) attaches the anti-slip | skid materials 121 and 111 on the slope 12 and the bottom face 11 of the main body 10 shown to (B), respectively. This is the same as the door stopper 1 shown in FIG.

  For usage, the door stopper 1 is placed on the floor surface 4 at a desired position where the door 2 is desired to be opened with the wedge-shaped mountain facing the wall surface 3, and the lower surface of the door 2 is pressed against the slope 12 of the door stopper 1. . The main body 10 is deformed to be in a state where it is bitten into the gap between the lower surface of the door 2 and the floor surface 4, and the contact area between the lower surface of the door and the inclined surface 12 is increased. Is fixed. When canceling, if the door 2 is pulled strongly in the direction in which the door 2 is closed, the door 2 comes off and the door stopper 1 remains. When it is desired to fix the door 2 again, the door 2 may be pressed against the slope 12 of the door stopper 1 as described above. There is an effect that the door 2 can be fixed or released simply by placing the door stopper 1 at a desired position on the floor surface 4.

The door stopper 1 of Example 2 is demonstrated based on FIG. FIG. 2A is a perspective view of the wedge-shaped door stopper 1 in which the main body 10 is made of foam, and FIG. 2B is a perspective view of the anti-slip material 121 on the slope of FIG. (C) is a perspective view of the main body 10 of (A) made of a foam having an anti-slip function, and the anti-slip material 121 on the slope is removed, and (D) is a fine anti-slip on the slope 12 of (C). It is a perspective view of what was made into the unevenness | corrugation 122 and widened.

  In the door stopper 1 shown in FIG. 1A, the wedge-shaped main body 10 is made of a foam, and an anti-slip material 121 is provided on a slope, and an anti-slip material 111 is provided on a bottom surface. The usage is the same as that in the first embodiment.

  The door stopper 1 shown in (B) is obtained by providing the anti-slip material 121 of the door stopper 1 shown in (A) with a fine unevenness 122 that prevents slipping. The shape of the unevenness 122 is a wave shape. Since the anti-slip property is improved, an anti-slip material having a poor anti-slip property can be used. The usage is the same as that in the first embodiment.

  The door stopper 1 shown in (C) is a construction in which the main body 10 is made of a foam having antislip properties, and an antislip material provided on the slope 12 can be omitted. The usage is the same as that in the first embodiment.

  The door stopper 1 shown in (D) has a wide width by making the slant surface 12 of the door stopper 1 shown in (C) with a fine unevenness 122 that prevents slipping. The cross-sectional shape of the fine irregularities 122 is easy to slip when the lower surface of the door is pressed, and conversely, it is difficult to slip in the direction of removing the door. Therefore, the wedge shape stands diagonally toward the higher side and vertically toward the lower side. Make it serrated. Since the slip resistance is further improved by the widening and the fine irregularities of the sawtooth shape, a flexible body having a poor slip resistance can be used. The usage is the same as that in the first embodiment.

  In any case, since the main body 10 is a foamed flexible body, it is generally possible to reduce the weight, and there is an effect that the cost can be reduced although there are exceptions. The anti-slip property is improved when the non-slip fine irregularities 122 are provided.

  The door stopper 1 of Example 3 is demonstrated based on FIG. FIG. 3 (A) shows that the main body 10 of the wedge-shaped door stopper 1 is made of foam, a rubber plate having door bottom holding pieces 123 at equal intervals is provided on the slope as an anti-slip means, and an anti-slip material 111 is provided on the bottom surface. (B) is a perspective view of the wedge-shaped rubber main body 10 having a hollow portion provided with the door lower surface holding pieces 123 at equal intervals and the anti-slip material 111 provided on the bottom surface. (C) is a side view of a case where the main body 10 of (A) is a solid flexible body 10 and a large number of small suction cups 112 are provided as anti-slip means on the bottom surface, and (D) is a cross-sectional perspective view showing the prior art.

  The door stopper 1 according to the third embodiment is characterized in that the door lower surface holding pieces 123 are provided on the slope at equal intervals slightly wider than the thickness of the door 2. Since the door lower surface holding piece 123 has a triangular prism shape and is inclined, if the door lower surface holding piece 123 is pushed from the lower side of the inclined surface, the door lower surface holding piece 123 is easy to fall down and easily get on. On the other hand, when it is pushed from the top, it is easy to fall down because of its vertical position. Therefore, when the lower surface of the door hits the door stopper 1, the lower surface of the door slides and tilts the door lower surface holding piece 123 and is fitted and fixed between the door lower surface holding pieces 123. Since the main body 10 is a flexible body, when pressed by the lower surface of the door, the slope is slightly recessed and becomes nearly horizontal. When releasing, when the door 2 is pulled strongly, the door lower surface holding piece 123 falls down and comes off.

  (A) is a flexible body in which the main body 10 is a foam. As shown in (B), there is a case where the main body 10 is hollow, that is, a rubber plate is formed in a frame shape. The elasticity of the rubber plate provides flexibility. (C) is a solid flexible body of the main body 10 of (A).

  In the prior art, as shown in (D), there is a main body with a U-shaped cross-section, but the purpose is to reduce weight, save material, and reduce the molding time. Therefore, even if pushed from above, it does not deform, maintains a wedge shape, and has a different purpose from that of the third embodiment.

  The usage is the same as that in the first embodiment.

 Since the door stopper 1 according to the third embodiment includes the door lower surface holding piece 123 as an anti-slip means, the door lower surface holding has an effect of increasing certainty.

  The door stopper 1 of Example 4 is demonstrated based on FIG. 4A is a perspective view of the main body 10 composed of two plates and a spring, and FIG. 4B is a perspective view of the main body 10 formed of a non-slip flexible body, with fine W-shaped irregularities 122 on the slope in the longitudinal direction. (C) is a cross-sectional view taken along the line XX of (B), (D) is a corner angle of the fine irregularities 122 of (C) that are alternately inverted from a W shape to a U shape. FIG. 5E is a cross-sectional view of the fine irregularities 122 of FIG. 8C changed from a W shape to a smooth curved waveform.

  The door stopper 1 shown in the fourth embodiment is a development of the main body 10, and (A) attaches anti-slip materials 121 and 111 to the slope and bottom surface of the main body 10 composed of two plates and a spring 101, respectively. It is a thing. (B) is a non-slip foam flexible body that forms a wedge-shaped main body 10 and is provided with W-shaped fine irregularities 122 on the slope in parallel with the longitudinal direction. (C) is the XX sectional view taken on the line of (B). (D) changes the fine unevenness | corrugation 122 of (C) from the W shape to the angled shape which repeats reversely the U shape alternately. (E) changes the fine unevenness | corrugation 122 of (C) from the W shape to the waveform which repeats a smooth curve alternately.

  (A) is obtained by substituting the softness of the flexible body with the spring 101. The flexibility is adjusted by the strength of the spring 101. If the slope plate is also thin, it will deform somewhat due to its elasticity. Since the anti-slip material 121 provided on the slope is also slightly deformed, the lower surface of the door rides on this and is fixed. In (B) to (E), fine irregularities 122 are provided in the longitudinal direction on the slope, so that the contact area is smaller than the bottom surface and the frictional resistance is also reduced. Therefore, since the slope has a lower frictional resistance than the bottom, when the door lower surface hits, the door stopper 1 does not move relative to the floor surface 4, and the door lower surface rides on the slope and is fixed by the frictional resistance. The frictional resistance is adjusted by the spring, the material of the flexible body, the size, number, and shape of the irregularities.

  The usage is the same as that in the first embodiment.

  In the door stopper 1 of the fourth embodiment, the door stopper (A) can adjust the ease of biting into the lower surface of the door by adjusting the strength of the spring 101, the thickness of the plate, and the material, and from (B) to (E) The thing has the effect that the ease of biting and the frictional resistance can be adjusted by the material of the flexible body, the size, number, and shape of the unevenness in the longitudinal direction.

  The door stopper 1 of Example 5 is demonstrated based on FIG. 5A is a perspective view of the wedge-shaped door stopper 1 slope and anti-slip material 121 shown in FIG. 5C of the first embodiment having a concave curved surface 121, and FIG. 5B is the slope and anti-slip of FIG. (C) is a perspective view of the sloped surface of (B) and the anti-slip material 121 is a curved surface 121 of repeated irregularities, (D) is (C) of Example 1. A perspective view of the wedge-shaped door stopper 1 shown in FIG. 2 in which the bottom surface, the slope, and the anti-slip materials 111, 121 are inverted drum-shaped (inflated), (E) is a plan view of (D), and (F) is a view of (D). The perspective view of what made the bottom face, the slope, and the anti-slip | slip-proof materials 111 and 121 into the drum shape (medium hollow shape), (G) is a top view of (F).

  The door stopper 1 shown in the fifth embodiment indicates that the shape is not limited to the wedge shape but may be other shapes. You may provide the uneven | corrugated fine unevenness | corrugation in the surface of the slip prevention material 121 of a slope. There is an effect of improving the slip resistance. The side shape of (D) and (F) is a triangle like the wedge shape. The main body 10 of the door stopper 1 of the fifth embodiment is solid, but may be a foam. You may make the side shape of (D) and (F) into the shape containing a curve like (A), (B), (C).

  The usage is the same as that in the first embodiment. The door stopper 1 of (A) has an effect that the door stopper 1 can easily bite into the gap between the lower surface of the door 2 and the floor surface 4. The door stopper 1 of (B) has an effect that when the flexible body of the main body 10 is soft, it has a large contact area and a high holding function when it bites under the lower surface of the door. The door stopper 1 of (C) has an effect that the contact area is large and the holding force of the door 2 is strong when the lower surface of the door rides up to the concave portion. The effects of the door stopper 1 of (D) and (F) are not much different from those of a wedge shape.

  The door stopper 1 of Example 6 is demonstrated based on FIG. 6A is a plan view showing the door stopper 1 according to the sixth embodiment, FIG. 6B is a cross-sectional view taken along line YY of FIG. 6A, and FIG. 6C is an anti-slip material for the slope of that shown in FIG. The cross-sectional view which shows what provided the fine unevenness | corrugation 122 of slip prevention except 121, (D) changes the main body 10 of what is shown to (C) into the foam with anti-slip property, and the fine unevenness 122 of the slip prevention of a slope. 4E is a cross-sectional view of the bottom with the anti-slip material 111 removed, (E) is a cross-sectional view of the main body 10 with a cavity shown in (C), and (F) is a flat plate under the wedge-shaped main body 10. The perspective view of what attached the anti-slip material 111 to the bottom face of the shape-like main body 10, (G) is the back of what assembled the wedge-shaped main body 10 of (F) and the flat plate-like main body 10 with the anti-slip material 111 by the fitting part 102 FIG.

  The door stopper 1 of Example 6 from (A) to (E) has a trapezoidal cross-sectional shape with a wide bottom surface. The vertical cross-sectional shape (parallel to the longitudinal direction of the slope) is the same as the wedge shape and is a triangle. The door stopper 1 of (F) and (G) has a flat bottom surface. The thing of Example 6 has the characteristic that the frictional resistance with respect to the floor surface 4 becomes large because the bottom area is large. When placed on the floor surface 4, it is more stable than the wedge shape. The top and bottom are clearly visible, and the slope 12 and the bottom surface 11 can be easily distinguished.

  The door stopper 1 shown in (A) and (B) is obtained by changing the cross-sectional shape of the wedge-shaped door stopper 1 of Example 1 from a rectangle to a trapezoid to increase the bottom area, and the main body 10 is solid.

  The door stopper 1 shown in (C) is provided with unevenness 122 having fine anti-slip on the slope, except for the anti-slip material 121 on the slope of the door stopper 1 in (B). The main body 10 is a solid flexible body and has a high frictional resistance. An anti-slip material 111 is attached to the bottom surface.

  The door stopper 1 shown in (D) is obtained by replacing the main body 10 of the door stopper 1 in (C) with a foam anti-slip flexible body and removing the anti-slip material 111 on the bottom surface 11. The main body 10 uses a flexible body having a large frictional resistance, and since the area of the bottom surface 11 is large, the frictional resistance with respect to the floor surface 4 is larger than that of the inclined surface 12 and the door 2 can be fixed. That is, the door stopper 1 can be made of a single non-slip flexible body.

  The door stopper 1 shown in (E) is obtained by hollowing the main body 10 of the door stopper 1 in (C), and can be deformed by the elasticity of the wall (plate) -like main body 10, and the lower surface of the door 2 and the floor surface. 4 into the gap.

  A door stopper 1 shown in (F) is a plate-shaped main body 10 attached to a wedge-shaped main body 10, and an anti-slip material 111 is provided below the bottom surface.

  In (G), the wedge-shaped main body 10 and the flat plate-shaped main body 10 of (F) are assembled by a fitting portion 102, and an anti-slip material 111 is attached below the bottom surface. Because it is an assembly type, it is not bulky during inventory, transportation and storage.

  The usage is the same as that in the first embodiment. Since the bottom area is large, the frictional resistance with the floor surface 4 is also large and difficult to slide, and there is an effect that the stability is good when placed on the floor surface 4. The distinction between the top and bottom is clearly understood, and the slope and the bottom can be easily distinguished. Since the bottom surface 11 has a larger area than the slope 12 and has a larger frictional resistance, there is an effect that it is possible to make a door stopper that can be fixed and released only by the door with a single anti-slip flexible body.

  The door stopper 1 of Example 7 is demonstrated based on FIG. 7A is a perspective view showing the door stopper 1 according to the seventh embodiment, FIG. 7B is a perspective view of the door stopper 1 of FIG. 7A provided with a spring receiving adjustment portion 113 of the spring material 12, and FIG. It is a perspective view of what made the spring material 12 of A) into concave shape.

  The door stopper 1 of Example 7 uses a thin leaf spring material 12 as a flexible portion of the main body 10. An anti-slip material 121 is attached to the surface of the spring material 12. The main body 10 is configured by bending a metal plate into an L shape in consideration of the thickness of the tip. The main body 10 is hollow. One spring material 12 may be bent to constitute the main body 10.

  (A) is a structure in which a thin leaf spring material is provided in a convex curved shape to form a slope 12, an anti-slip material 121 is attached to the surface, and an anti-slip material 111 is attached to the bottom surface.

  (B) is a structure in which a plurality of groove-like spring receiving adjustment portions 113 are provided at the tip of the bottom surface of the main body 10. The tip of the spring material 12 is fitted into one of the grooves of the spring adjusting portion 113 and fixed. The height of the slope 12 and the strength of the spring are adjusted by selecting the groove of the groove-like spring receiving adjustment portion into which the tip of the spring material 12 is fitted.

  (C) reverses the curved state of the spring material 12 of (A), and makes it concave (convex downward). Others are the same as (A).

  The usage is the same as that in the first embodiment.

  The door stopper 1 of (A) can adjust the ease of entering the gap between the door lower surface and the floor surface 4 and the holding force of the door lower surface by adjusting the elastic strength of the spring material 12. In (B), since there is the spring receiving adjustment portion 113, the height and elasticity of the spring material 12 can be adjusted. (C) has the effect that it is easy to enter the gap between the lower surface of the door 2 and the floor surface 4 because the tip is thin.

  The door stopper 1 can be applied when it is desired to fix the door 2 at an arbitrary position.
