Abstract

PROBLEM TO BE SOLVED: To contrive not to damage a floor face without any deformation in repeated use by acutely projecting an inclined side plate from one of a bottom side plate in the form of a hollow wedge on the whole, and projecting a support piece toward the bottom side plate from the upper end of the inclined side plate. SOLUTION: A strip-like inclined side plate 2 is provided to be projected from one edge of a striplike bottom side plate 1 so that the whole is in the form of a hollow wedge. Furthermore a support piece 3 is provided toward the bottom plate 1 from the inclined upper end part of the inclined side plate 2, and an angle formed by the support piece 3 and the inclined side plate 2 is an acute angle. Thereby the inclined side plate 2, with its edge part as a fulcrum, come to have spring property, and is inserted in a gap between a swing door and a floor to push up the swing door so as to be fixed. The force in the direction of insertion is relaxed by the spring property to prevent deformation. Furthermore, when the inclined side plate 2 is pushed to bring the tip part of the support piece into contact with the bottom side plate 1 and deformation begins in the direction of the inclined plate 2, a resistance is generated, and it prevents the spring from reaching the elastic limit to prevent breakage of a door stopper.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door stopper used for a swing door or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
Although there are various materials such as resin and synthetic rubber, a door stopper (c) having a substantially wedge-shaped cross section has been used by being inserted into the gap between the swing door 5 and the floor 6.

[0003]

However, these existing door stoppers, for example, when made of wood or resin, need to be firmly inserted into the gap between the swing door and the floor surface in order to securely fix the swing door. Because of this, a stepped portion due to deformation was formed on the inclined surface of the door stopper by the swing door, and it was necessary to insert it more firmly into the gap to fix the swing door if it was used repeatedly. .

When a synthetic rubber is used to provide resilience in order to prevent a step from being formed on an inclined surface due to deformation, although the above problem is solved, the frictional force of the bottom surface is strong, so that the insertion is difficult. Sometimes the floor surface will rub, so if the floor surface is a tatami surface, after the door stopper rubs on the floor surface, it will remain, so if you eliminate the frictional force on the bottom surface,
This time, there was a risk that the door stopper would come off due to the restoring force of the main body.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door stopper which does not deform the repeated use and does not damage the floor surface.

[0006]

According to a first aspect of the present invention, there is provided a door stopper in which a band-shaped oblique plate is entirely hollow and substantially wedge-shaped from one substantially end of a band-shaped bottom plate. This is a resin door stopper that protrudes.

[0007] Therefore, since the band-shaped oblique plate protrudes from one substantially end of the band-shaped bottom plate so as to have a hollow substantially wedge shape, the oblique plate has spring property with the front end portion as a fulcrum. In other words, the swing door is fixed in such a manner that it enters the gap between the swing door and the floor surface and the oblique plate pushes the door upward from the lower side of the swing door, so that the swing door can be firmly fixed. For this reason, in the past, while pushing in the insertion direction and applying force, at the same time generating a restraining force upward, the door stopper itself induced constant deformation, but with the door stopper of the present invention, in the insertion direction, Since the force of the door stopper is reduced by the spring property, the deformation of the door stopper, which has conventionally occurred, can be suppressed.

Further, due to the resiliency, the gap between the swing door and the floor surface may be various in the construction state, but any gap can be accommodated.

The door stopper according to a second aspect of the present invention is the door stopper according to the first aspect, wherein a supporting piece projects from a substantially upper end portion of the oblique plate toward the bottom side plate. The door stopper has an acute angle.

[0010] Therefore, since the support piece protrudes from the substantially upper end portion of the oblique plate toward the bottom plate, and the angle formed between the support piece and the oblique plate is acute, the support piece and the oblique plate are further substantially wedge-shaped. And have spring properties.
Therefore, when inserting the door stopper, if the oblique plate is pushed down by the lower end of the door and deforms downward, if it deforms more than a certain amount, the tip of the support piece contacts the bottom plate and the support piece moves in the oblique plate direction. That is, it starts to deform in the direction in which the spring property occurs. Therefore, since the spring property of the support piece indirectly resists the insertion of the door stopper, it is possible to prevent the door stopper from being inserted more than necessary to reach the elastic limit of the spring, and to eliminate the possibility of breaking the door stopper.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 5 show a first embodiment of the present invention according to claim 1 or 2. FIG.

A door stopper (a) according to a first embodiment of the present invention is configured such that a band-shaped oblique plate 2 is formed into a substantially hollow wedge shape from substantially one end of a band-shaped bottom plate 1. Further, a support piece 3 is protruded from a substantially upper end portion of the oblique plate 2 toward the bottom plate 1, and an angle between the support piece 3 and the oblique plate 2 is an acute angle door stopper.

Therefore, since the band-shaped oblique plate 2 protrudes from substantially one end of the band-shaped bottom plate 1 so as to have a substantially hollow wedge shape as a whole, the oblique plate 2 has a spring at the front end portion as a fulcrum. And the oblique plate 2 enters the gap between the swing door 5 and the floor surface 6 and is fixed by pushing the swing door 5 upward from the lower side of the swing door 5,
The swing door 5 can be firmly fixed. For this reason, in the related art, the door stopper (c) itself has been induced to constantly deform in order to generate a pressing force at the same time while applying a force by pushing in the insertion direction. In (a), since the force in the insertion direction is reduced by the spring property, the deformation of the door stopper (c), which has conventionally occurred, can be suppressed.

Further, due to the resiliency, the gap between the swing door 5 and the floor 6 may be various in the construction state, but any gap can be accommodated.

Further, a support piece 3 is protruded from a substantially upper end portion of the oblique plate 2 toward the bottom plate 1, and the support piece 3 and the oblique plate 2
The support piece 3 and the hypotenuse plate 2
Both have a substantially wedge shape and have spring properties. Therefore, when inserting the door stopper (a),
When the hypotenuse plate 2 is pressed by the lower end of the swing door 5 and deforms downward, when the hypotenuse plate 2 is deformed by a certain amount or more, the tip of the support piece 3 comes into contact with the base plate 1 and the support piece 3 is moved in the direction of the hypotenuse plate 2, That is, it starts to deform in the direction in which the spring property occurs. Therefore, since the spring property of the support piece 3 indirectly resists the insertion of the door stopper (a), it is possible to prevent the door stopper (a) from being inserted more than necessary to reach the elastic limit of the spring,
There is no danger of breaking the door stopper (a). In the present embodiment, the corner of the lower end of the support piece 3 of FIG. 1 is formed round, so that the support piece 3 can slide without being caught after coming into contact with the base plate 1, and the door stopper (a) Can be inserted smoothly.

Further, in the present embodiment, as shown in the side view in FIG. 1, a concave portion formed by a curved surface is formed at a tip portion formed by the bottom plate 1 and the oblique plate 2. As a result, if the tip portion is formed without taking a curved surface, the tip portion may be broken by stress concentration due to elastic force, but this is prevented beforehand.

As shown in FIGS. 1 and 3, the hypotenuse plate 2 has ribs 4 formed integrally over substantially the entire length for reinforcing the strength. Further, since the step is formed on the upper surface of the substantially distal end portion of the support piece 3 side, even if the door stopper (a) is fully inserted, the step hangs on the lower portion of the swing door 5. , Preventing the entire body from being pushed. At the same time, since it is formed thick, it also has a role of preventing destruction.

Further, as shown in FIG. 4, the bottom plate 1 is tapered in the horizontal direction of the cross section. Therefore, the contact area with the floor surface 6 during use can be reduced, and the floor surface 6 is less likely to be damaged even if the bottom surface of the bottom plate 1 is slid in contact with the floor surface 6 during insertion. Therefore, for example, the tatami mat may become the floor surface in the opening and closing direction of the swing door 5, but even in this case, the risk of damaging the tatami mat surface is reduced.

In addition to the above-mentioned effect of preventing the support piece 3 from being excessively inserted, when the door stopper (a) is removed, the support piece 3 is held and the door stopper (a) is pulled out. Can be handled easily.

FIG. 6 is a diagram showing a second embodiment of the present invention according to claim 1. In this embodiment, a door stopper (b) is formed by protruding a band-shaped oblique plate 2 from one substantially end of a band-shaped bottom plate 1 so as to form a hollow substantially wedge shape. The inclined upper end portion of the oblique plate 2 is bent so as to be substantially parallel to the base plate 1, and further bent substantially vertically from the longitudinal end of the base plate 1 so as to protrude upward, and further projecting ends The part is bent again in the original direction to form it. Further, the periphery of the end portions of the oblique plate 2 and the bottom plate 1 is formed so as to have a certain gap.

As a result, the band-shaped oblique plate 2 protrudes from substantially one end of the band-shaped bottom plate 1 so as to have a substantially hollow wedge shape as a whole. It has a spring property, and the oblique plate 2 enters into the gap between the swing door 5 and the floor surface 6 and is fixed in such a manner that the swing door 5 is pushed up from below the swing door 5,
The swing door 5 can be firmly fixed. For this reason, in the past, the door stopper (c) itself was constantly deformed in order to generate a pressing force at the same time while applying a force by pushing the door stopper in the insertion direction. In b), since the force in the insertion direction is reduced by the spring property, the deformation of the door stopper, which has conventionally occurred, can be suppressed.

Further, due to the resiliency, the gap between the swing door 5 and the floor 6 may be various in the construction state, but any gap can be accommodated.

Further, by pinching the end portions of the oblique plate 2 and the bottom plate 1, the wedge shape can be deformed and the insertion can be facilitated. In addition, the bottom plate 1 can be pulled out while holding the upwardly projecting portion.

[0024]

As described above in detail, according to the door stopper of the first aspect, the band-shaped oblique plate has a hollow substantially wedge-like shape from one substantially end of the band-shaped bottom plate. As a result, the oblique plate has spring property with the tip portion as a fulcrum, and the oblique plate enters the gap between the swing door and the floor surface, and fixes the swing door in a form that pushes the door from below the swing door. In other words, the swing door can be firmly fixed. For this reason, in the past, while pushing in the insertion direction and applying force, at the same time generating an upward restraining force, the door stopper itself was constantly deformed to induce it, but with the door stopper of the present invention, in the insertion direction, Since the force of the door stopper is reduced by the spring property, the deformation of the door stopper, which has conventionally occurred, can be suppressed.

Further, due to the resilience, the gap between the swing door and the floor surface may be various in the construction state, but any gap can be accommodated.

According to the door stopper of the second aspect,
Since the support piece protrudes from the substantially upper end portion of the oblique plate toward the bottom plate, and the angle between the support piece and the oblique plate is made acute, the support piece also has spring properties. Therefore, when inserting the door stopper, if the oblique plate is pushed down by the lower end of the door and deforms downward, if it deforms more than a certain amount, the tip of the support piece contacts the bottom plate and the support piece moves in the oblique plate direction. That is, it starts to deform in the direction in which the spring property occurs. Because of this, the spring property of the support piece indirectly resists the insertion of the door stopper, preventing the door stopper from being inserted more than necessary and reaching the elastic limit of the spring,
There is no longer any risk of breaking the door stopper.
