Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door stopper for maintaining a door in an open state, and mainly relates to a door stopper for maintaining a swinging door biased in a normally closing direction in an open state.
[0002]
[Prior art]
As this type of door stopper, for example, as in the conventional example shown in FIG. 9, a swing that is normally biased in a closing direction by a biasing means (not shown) such as a door closer attached above the door 11. A wedge shape used for the door 11 is widely used.
[0003]
The door stopper 15 prevents the door 11 from being closed when the door 11 is opened for indoor ventilation or the like, and an infant does not jam in the gap between the side surface 11 b of the closed door and the door frame 12. Used to keep the door 11 open. That is, by inserting the wedge-shaped door stopper 15 into the gap between the door lower edge 11a and the floor surface 14 with the high side of the inclined surface 15a positioned on the closing direction side, the force that the door 11 tries to return to the closing direction. Therefore, the wedge effect is exerted by increasing the force with which the door 11 pushes the floor surface 14 through the door stopper 15, and the door 11 is maintained in the open state.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional example, when the door stopper 15 is slid and moved on the floor 14 against the force of the door 11 to close, the swinging door with a strong urging force closes immediately, or as described above, There was a risk of clogging with fingers.
[0005]
In addition, since the insertion position of the door stopper 15 is at the lower end of the door 11, there is a problem that it is difficult to handle because a bending operation is required.
[0006]
Further, when the door stopper 15 is not used, it is placed in the corner of the floor near the door 11, but there is also a problem that it is inconvenient to use because it cannot be prepared immediately in the case of frequent use.
[0007]
Therefore, the present invention can select two usage methods corresponding to the purpose of use, usability, door structure, etc., and can be used safely by using two different usage methods at the same time. The object is to provide a door stopper that can be hooked and stored and is convenient to use.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has an inclined surface that presses against the door lower edge when interposed in the gap between the floor surface and the door lower edge, and is a side view for maintaining the door in an open state. and the wedge portions includes a boundary portion between the base end portion of the wedge portion, is interposed between the door side and the door frame and a side view for maintaining the door in a predetermined angle or more open A substantially triangular hinge holding portion having an angle θ directed toward the wedge portion side, and a boundary portion on the side opposite to the wedge portion of the hinge holding portion, and when the hinge is engaged with the hinge of the door And a hook portion that interposes the sandwiching portion between the side surface of the door and the door frame, and is integrally formed of an elastic material, and the wedge portion has a bottom surface facing the floor surface in a gap between the floor surface and the door lower edge. The thickness of the boundary portion between the proximal end portion and the hinge holding portion is smaller than that of the hinge holding portion. Ikoto, the bottom, characterized in that characterized in that to avoid contact with the floor surface.
[0009]
According to the present invention, when the sloped side of the wedge portion is positioned at the closing direction side of the door that is normally biased in the closing direction and inserted into the gap between the door lower edge and the floor surface, for example. The door is half-opened or fully-opened due to the wedge effect that the inclined surface presses against the lower edge of the door and the force that the door pushes the floor through the door stopper is greater than the force that the door returns to the closing direction. Can be maintained in a state. In particular, when the wedge portion is interposed in the gap between the floor surface and the door lower edge with the bottom surface facing the floor surface, the thickness of the boundary portion between the proximal end portion and the hinge holding portion is larger than that of the hinge holding portion. Since the bottom surface does not touch the floor surface, it is sandwiched between the lower edge of the door and the floor surface, and the inclined surface is pressed against the lower edge of the door, so that it bends downward and reaches the floor surface at its tip. Can work in pressure contact.
[0010]
In addition, when the hook portion is hooked on the door hinge and the hinge holding portion is interposed between the door side surface and the door frame, the hinge holding portion is formed at a position greater than a predetermined angle at the interposed position. The door can be kept open. In other words, even if the door is closed, it can be stopped at a predetermined angle and cannot be closed any further (in the case of a door that is always biased in the closing direction, the door stopper is positioned at the predetermined angle at the door side and the door frame. And can be fixed in an open state at that angle). Since it can be operated at the hinge position in this way, it is not necessary to bend and insert, so it is easy to use and can be used with extremely simple operation.
[0011]
As described above, in the present invention, the wedge portion is inserted into the gap between the lower edge of the door and the floor surface, and the hook portion is hooked on the hinge and the hinge holding portion is interposed between the door side surface and the door frame. However, if each door is used with two door stoppers, the door stopper using the wedge part should come off, or the door may slip on the floor due to reduced wedge effect. Even if the door is closed, the hinge interposition part can prevent the door from closing, so that it can be used safely. In addition, any one of them can be selected and used in accordance with the purpose and convenience of use of the door stopper, the structure of the door, etc., so that the range of use is widened and convenient for use.
[0012]
The hook part is for hooking on the hinge, but when not in use, the hook part is hooked to the appropriate place near the door (it can be hooked to the shaft of the door knob or door lever depending on the shape and material). Further, as described in claim 2, by forming the hook portion so that it can be hooked on the shaft portion of the door knob or door lever, the shaft portion of the door knob or door lever can be easily attached. It can be hooked and stored, and in the case of frequent use, it can be prepared immediately and it is not necessary to bend down, so that it is easy to handle in this respect and is very convenient to use.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the door stopper of the present invention will be specifically described with reference to FIGS. The use of the wedge portion is the same as that of the conventional example shown in FIG. In this embodiment, the door stopper is shown as an example when used for a swing door that is normally biased in the closing direction.
[0014]
The door stopper 1 of the first embodiment is an inclined surface that presses against the bottom surface 2a facing the floor surface 14 and the door lower edge 11a as shown in the external perspective view of FIG. 1, the plan view of FIG. 2, and the side view of FIG. 2b, the wedge part 2 formed in a wedge shape, the hook part 3 that can be hooked on the hinge 13 (FIG. 4) of the door 11, and the hook part 3 as shown in FIG. When hooked on the hinge 13 of the door 11, the hinge 11 is interposed between the door side surface 11 b and the door frame 5, and is configured with a hinge clamping portion 4 for maintaining the door 11 in an open state at a predetermined angle.
[0015]
When the door stopper 1 is integrally formed of an elastic material such as rubber or synthetic resin having a relatively large coefficient of friction on the surface, the door stopper 1 is brought into contact with the inclined surface 2b of the wedge portion 2 and the door lower edge 11a or to the hinge 13 of the hook portion 3. This is preferable because the hooking state on the door knob or the like is good. Although not shown, if a through-hole is opened at an appropriate position in the thick portion of the door stopper 1, it is possible to prevent sink marks during cooling of the molding material.
[0016]
There are the following two methods for maintaining the door 11 in the open state using the door stopper 1.
[0017]
First, when the door 11 is kept open using the wedge part 2, the wedge part 2 is positioned on the side of the door 11 in the closing direction A as shown in FIG. Insert into the gap between the door lower edge 11b and the floor 14. Then, the inclined surface 2b comes into pressure contact with the door lower edge 11a, the wedge part 2 bends downward as shown by the phantom line, the tip end part comes into pressure contact with the floor surface 14, and the door 11 is closed by a biasing means (not shown). The wedge effect is exerted by the force by which the door 11 pushes the floor surface 14 through the door stopper 15 rather than the force to return to A, and the door 11 can be maintained in the half-open or fully-open state.
[0018]
Regarding the wedge part 2 of the first embodiment, the thickness of the base end part in a side view state is about ½ of the thickness of the hinge sandwiching part 4 at the boundary part. 2a is not in contact with the floor surface 14, but the wedge part 2 is sandwiched between the door lower edge 11a and the floor surface 14, and the inclined surface 2b is bent downward by being pressed by the door lower edge 11a. The portion comes into pressure contact with the floor surface 14. It is also possible to form the entire bottom surface 2a of the wedge part 2 so as to be in contact with the floor surface 14 (the thickness of the base end part of the wedge part 2 matches the thickness of the boundary part of the hinge holding part 4). However, it is preferable to form as in the first embodiment because the bending force can be utilized, the molding material can be reduced, and the cost can be reduced.
[0019]
On the other hand, when the door 11 is maintained in an open state by using the hinge clamping portion 4 instead of the wedge portion 2, the hook portion 3 is connected to the gap 5 between the door side surface 11b and the door frame 12 as shown in FIG. Is inserted into the door 11 from above and hooked onto the hinge 13 of the door 11. Then, with the side surface portion in FIG. 3 facing upward, the hinge clamping portion 4 is clamped between the door side surface 11b and the door frame 12, and the door 11 is substantially triangular in side view of the hinge interposition portion 4. It is fixed in an open state at an angle θ of the shape. In the case of a door having no urging means, the door 11 is interposed between the side surface 11b of the door 11 opened at a desired angle and the door frame 12, and the door 11 is closed even if the door 11 is closed due to an impact. It can be stopped at an angle θ and will not close any further. That is, the door 11 can be maintained in an open state with an angle θ or more. In this way, when the hinge clamping part 4 is used, it is not necessary to bend and insert it into the lower end of the door 11, so that it is easy to use and can be used with an extremely simple operation.
[0020]
As described above, in the first embodiment, the wedge portion 2 is inserted into the gap between the door lower edge 11a and the floor surface 14, and the hinge clamping portion 4 is the hinge 13 portion between the door side surface 11b and the door frame 12. There are two methods of use, such as interposing between them, but if each method of use is used with two door stoppers at the same time, the door stopper 1 using the wedge part 2 will come off, the wedge effect will be reduced, etc. Therefore, even if the door 11 is closed by sliding on the floor surface 14, the hinge clamping portion 4 can prevent the door from closing, so that it can be used safely. In addition, since it is possible to select and use any one of them in consideration of the purpose and convenience of use of the door stopper 1, the structure of the door 11, and the like, the range of use is widened and convenient for use.
[0021]
In addition, the hook portion 3 is for hooking on the hinge 13, but the first embodiment is formed of an elastic material such as rubber or synthetic resin for the entire door stopper 1, so that its elastic force is used, When not in use, as shown in FIGS. 5 and 6, the hook portion 3 can be hooked on the door knob or the shaft portion 9 a of the door lever 9 and stored.
[0022]
7 and 8 show a second embodiment of the present invention. The door stopper 21 has the same basic structure as that of the first embodiment including the wedge portion 7 having the inclined surface 7b, the hook portion 8, and the hinge clamping portion 6, but the bottom surface 7a of the wedge portion 7 and the hinge The thickness and shape of the holding part 6 for use differ from the shape of the hook part 8. That is, the hinge clamping portion 4 of the first embodiment has a substantially triangular shape in a side view not continuous with the bottom surface 2 a of the hook portion 2, and the bottom surface 2 a and the floor surface 14 when the door stopper 21 is placed on the floor surface 14. However, as shown in FIG. 8B, the hinge holding portion 6 of the second embodiment has a shape in which the bottom surface 7a of the wedge portion 7 is flush with the floor surface 14 as shown in FIG. Is formed. Since the material of the door stopper 21 of the second embodiment does not require the bending of the wedge portion 7, it may be wood or metal in addition to rubber or synthetic resin. Moreover, since the arc part 8a is formed in the hook part 8, even if it forms with a comparatively hard material, it can be latched and stored in the shaft parts 9a, such as a door knob and the door lever 9, frequently. In the case of use, since it can be prepared immediately and it is not necessary to bend down, it is easy to handle in this respect, and it is very convenient to use.
[0023]
The present invention can be configured in various aspects other than those shown in the above-described embodiment. For example, as long as the door can be maintained in an open state by using a wedge part or a pinching part for a hinge and a hook part, those can be used. The shape is not limited to that shown in the above embodiment.
[0024]
【The invention's effect】
According to the door stopper of the present invention, a method for inserting a wedge portion between a door lower edge and a floor surface and a method for ease of use with a very simple operation in which a hinge clamping portion is interposed between a door side surface and a door frame. The two usage methods can be selected and can be used safely by using each of the two usage methods at the same time. Depending on the material and shape of the hook, it can be hooked in place such as a door knob when not in use. It is also possible to do so and it becomes convenient to use. In particular, when the wedge portion is interposed in the gap between the floor surface and the door lower edge with the bottom surface facing the floor surface, the thickness of the boundary portion between the proximal end portion and the hinge holding portion is larger than that of the hinge holding portion. Since the bottom surface does not touch the floor surface, it is sandwiched between the lower edge of the door and the floor surface, and the inclined surface is pressed against the lower edge of the door, so that it bends downward and reaches the floor surface at its tip. Can work in pressure contact.
