Description

Specification

Dotono Tono Technical field

The present invention relates to a clip type door stopper mainly made of steel. Background art

In the past, in order to keep the half-opened door as it was, rust was left between the door and the floor.

Recently, barrier-free and flat floors have become mainstream in apartments, apartments, hospitals and offices. It is necessary to ventilate the room to prevent moisture retention for health. When ventilating, open the windows and entrance doors for the introduction of outside air and open the doors of the room, but when a gust of wind blows in, the doors of the room close with a strong force. I had a problem, was nervous, and was dangerous. So we need a door stopper.

The rusty door stalls must be kept close to the door when not in use, so the landscape is bad, often disturbing, and the usability is bad and inconvenient. The problem to be solved is the problem of these rusty door stoppers, and providing a door stopper that can be installed without using mounting screws that damage the door and floor, and that is not very noticeable. . Disclosure of the invention

In a clip in which the lever handle and the lever handle holding direction switching mechanism are installed in a pair on the spring body, the maximum clippable width of the clip is equal to or greater than the thickness of the door, and the installation length of the lever handle The spring book Provide a stopper that is longer than the height of the body (h) by a certain range, and the certain range is defined as the range of length that the lever handle can play a role as a flat bar while engaging with the floor surface. The door stopper is characterized in that the stopper is used under the door at the bottom.

In addition, a stopper formed by installing a lever handle and a lever handle holding direction switching mechanism on a plate member is provided, and the stopper is fixed to a side surface of the door and used.

In addition, the lever handle holding direction switching mechanism may be installed on an opposing pair of the panel main body, and the lever handle holding direction switching mechanism may be removed from one of the pair, and the door stopper described in the above or the other. did.

The product of the present invention is used in a clip type under the siding of the door, and naturally, it should be designed to achieve the purpose of sandwiching the door in a clip type. Therefore, the maximum clipable width of the clip should be equal to or greater than the thickness of the door.

The clipper has been applied as an embodiment in which the screw is screwed into the floor or the door to damage the screw and the complexity of the installation is eliminated. By putting the clip in the lower part of the door, nothing is hurt. The door stopper can be removed whenever it becomes unnecessary, and there are many doors without a locking mechanism even in apartments and apartments, but the door stopper of the present invention has also realized an effect as a simple locking. When the lever handle of the door stopper according to the present invention is turned over from inside the room, the door can no longer be pushed open from the outside. This effect is expressed as simple locking. Brief description of the drawings

BEST MODE FOR CARRYING OUT THE INVENTION

This will be described according to the accompanying drawings in order to describe the invention in more detail.

FIG. 1 is a perspective side view showing an embodiment of a door stopper, wherein 1 is a lever handle holding direction switching mechanism, 2 is a lever handle, 3 is a rubber body, and 4 is a spring body It is.

FIG. 2 is a perspective front view showing an embodiment of a door stopper, wherein 1 to 4 are the same as FIG.

FIG. 3 is a perspective plan view showing an embodiment of a door stopper, wherein 1 to 4 are similar to FIG.

FIG. 4 is a perspective view showing an embodiment of a door stopper, wherein 1 to 4 are similar to FIG. And 5 is a door, and it is a dashed dotted line showing an imaginary line Is drawing. Also, 6 is the floor. FIG. 4 shows a view in which both of the lever handles 2 installed in an opposing pair on the spring main body 4 are turned downward on the floor side using the lever handle holding direction switching mechanism 1. In this case, the door 5 can not pivot in either direction. In addition, the installation length of the lever handle is made longer than the height (h) of the panel main body by a certain range, and the certain range is a length that can play a role as a flat bar while the lever handle engages with the floor surface. Is an example defined as the range of

Here, the range of lengths that can play a role as a topping rod will be described based on Fig. 11. First, Fig. 11 is a conceptual diagram that explains the role of a top bar. The clearance distance between the interior door and the floor is determined to be 8 mm to 10 mm from the pointer for door installation, but in Fig. 11, the clearance is set to 0.2 mm (floor surface for simplification). It is assumed that there is almost no gap distance between 6 and 9). The distance D shown in FIG. 11 is the distance from the point H to the lower end of the lower ridge 9. When the length of the lever handle 2 is equal to or less than the distance D, a triangular area shown by the hatched portion in FIG. 11 can not be created, and a force triangle can not be established. I can not play a role. If the lever handle 2 length is 0.5 mm plus the distance D, it will be 0.3 mm longer than the length 0.2 mm plus the distance D, and in theory, it will be a slight diagonal line A triangular region as shown in the section is created, and a triangle of force can be established. With the fulcrums in Fig. 11 including the fulcrums (the contact points between the tip of the lever handle 2 and the floor 6) that exist in this slight case, each fulcrum is the pin fulcrum in terms of structural mechanics. Since the pin fulcrum has an upward reaction force, a triangle of force is established. If a force triangle is established, the lever handle 2 can play a role as a backrest bar.

Turning back, the B fulcrum in Fig. 1 1 has an extremely long lever handle 2 The fulcrum point (the point of contact between the tip of the lever hand 2 'and the floor 6). As the angle between the lever handle 2 'and the floor surface 6 becomes too shallow at this B fulcrum, the B fulcrum becomes the roller fulcrum (A fulcrum is the pin fulcrum) in terms of structural mechanics. Since no upward reaction force can exist on the roller fulcrum, a force triangle can not be established. If the force triangle does not hold, the lever handle 2, can not play a role as a bar. FIG. 5 is a perspective view showing an embodiment of a door stopper, wherein 1 to 6 are similar to FIG. This figure shows the lever handle 2 installed in the opposite pair on the panel main body 4 turned down using only the lever handle holding direction switching mechanism 1 downward on the floor surface side. In this case, the door 5 can pivot only in the direction in which the lever handle 2 is not overturned.

FIG. 6 is a perspective view showing an embodiment of a door stopper, and 1 to 6 are similar to FIG. This figure shows a view in which the lever handle 2 installed in the opposite pair on the panel body 4 is held upward using the lever handle holding direction switching mechanism 1. In this case, the door 5 can freely rotate in either direction.

FIG. 7 is a perspective view showing an embodiment of a door stopper, wherein 1, 2, 3, 5 and 6 are similar to FIG. 7 is a double-sided tape, 8 is a plate member. This figure shows an embodiment of a style in which the lever handle 2 and the lever handle holding direction switching mechanism 1 are installed on the plate member 8. Further, the installation length of the lever handle 2 is made longer than the height (h ') of the plate member by a certain range, and the certain range is the role of the lever handle 2 while being engaged with the floor surface. It is an example defined as the range of the length that can be carried. In this embodiment, the plate member 8 is fixed to the door 5 so that the lower end of the plate member 8 is substantially at the same position as the lower end of the lower ridge 9 of the door 5.

FIG. 8 is a perspective view showing an embodiment of a door stopper, which is 1, 2, 3,. 5, 6, 7 and 8 are the same as in FIG. This figure shows an embodiment of a style in which the lever handle 2 and the lever handle holding direction switching mechanism 1 are installed on the plate member 8. Also, in this embodiment, the installation length of the lever handle 2 is extremely longer than the height (h ') of the plate member. In this case, the lower end of the plate member 8 is positioned such that the lower end of the plate member 8 is raised from the lower end of the lower slat 9 of the door 5 by the distance d in FIG. Secure the member 8 to the door 5.

FIG. 9 is a perspective view showing an embodiment of the door stopper, wherein 1, 2, 3, 5, 6, 7 and 8 are similar to FIG. This figure shows a view in which the lever handle 2 installed on the plate member 8 is held upward using the lever handle holding direction switching mechanism 1. In this case, the door 5 can freely rotate in either direction.

Fig. 10 is a perspective view showing an embodiment of the door stopper, in which 1 is a lever handle holding direction switching mechanism, 2 is a lever handle, 5 is a door, and 6 is a floor surface. 7 is a double-sided tape, 8 is a plate member. The fixing position of the plate member 8 to the door 5 is the same as in the case of FIG. FIG. 10 shows an embodiment in which the rubber 3 is not installed on the lever handle 2.

The rubber member 3 of the lever handle 2 pivotally attached to the spring body 4 or the plate member 8 is pressed against the floor 6 by the lever handle holding direction switching mechanism 1. The lever handle 2 plays the role of a top bar. When the door 5 attempts to pivot, a downward force is generated at the fulcrums of the rubber member 3 and the floor surface 6.

The lever handle 2 is pivotally attached to the door 5 to be rotated, and the fulcrum between the rubber member 3 and the floor 6 is the reaction point of the pin fulcrum, so a downward force is generated and the reaction force is also satisfied. The pivoting of the door 5 must stop.

In FIG. 10, although the rubber member 3 is not installed on the lever handle 2, as described above, a downward force is generated and the reaction force is also satisfied. Even without the material 3, the pivoting of the door 5 can not stop. Modern flooring has cushioning material, and the effect of the downward force is enough to bite into the cushioning material. The rubber member 3 dramatically enhances the slip effect, and also serves as a shock absorbing material for preventing damage to the floor surface.

Although the gap between the floor 6 and the lower gusset 9 of the door 5 varies depending on the method of construction, the present invention device is a clip type, so the position to be clipped can be adjusted appropriately. If it is a very common gap, it can respond to any. 8 and 10 show an example in which the installation length of the lever handle 2 is made extremely long from the height (h ') of the plate member in FIG. This is an example of defensive technology disclosure this time in order to combat the case where there is an extreme gap with the lower stile 9 or a clip-type bypass device. This method is a method of fixing the stopper to the door 5 with the double-sided tape 7, and in this case also, the pivoting of the door 5 can be stopped.

As an example of implementation, the installation length of the lever handle 2 is made longer than the height (h) of the spring main body 4 within a certain range, and the certain range is 0.5 mm or more and the clearance distance between the door 5 and the floor. The effect of stopping the pivoting of the door also occurs if it is less than plus 5 mm. The term “0.5 mil or more” in this case means that if the lever handle 2 protrudes from the lower surface of the spring main body 4 by 0.5 mil or more, the effect of stopping the rotation of the door is generated. Even if the gap between the door and the floor is more than 0.5 mm, the door stopper according to the present invention is a clip type, so it is possible to attach the door stopper as close to the floor 6 as possible. is there.

As another example, when installing with the inner bottom surface of the spring main body 4 in close contact with the lower gusset 9 of the door 5, the installation length of the lever handle 2 is set to 5 mm plus the clearance distance between the door and the floor. If the length which protrudes from the lower surface of the panel main body 4 by the length of, the effect of stopping the rotation of the door is generated. This is already mentioned It is clear from the explanation of Fig. 1 1

In the above embodiment, depending on the mechanical clearance of the lever handle holding direction switching mechanism and the design change of the lever handle serving as a spacer, the definition of the above-mentioned range fluctuates or is proportional. In order to avoid unnecessary conflicts with future inventions, we will disclose it here. The same is true for changing the design of the rubber member in the name of increasing the stop effect.

If the lever handle 2 can play a role as a bar, it may not be 0.5 mm or more, and it may be 5 mm or more between the door and the floor. .

If the shape of the rubber member is devised, the pin fulcrum becomes a roller fulcrum, and the mechanical clearance of the lever handle holding direction switching mechanism also influences the formation of the force triangle.

There is no step between the lower end of the door and the floor, but the door frame often intervenes in the case of the front door. There is a step between them. And it is normal that a water gradient is taken on the floor surface. In order to make it possible to use the clip-type door stopper for a door that has such a circumstance, the lever handle holding direction switching mechanism was removed from one of the pair of lever handle holding direction switching mechanisms 1. In other words, Fig. 12 shows an example of a door stopper normally provided with a pair of lever handle holding direction switching mechanisms 1, but as shown in Fig. 14 (plan view), one lever handle holding direction is shown. The lever handle holding direction switching mechanism 1 was removed by cutting off the acute angle projection 1 0 of the switching mechanism 1. The portion shown by the dotted box in FIG. 14 is the original shape before removing the acute-angled projection 10. When the acute angle projection 10 is removed, the lever handle holding direction switching mechanism 1 no longer performs the lever handle holding switching function by the acute angle projection 10 As a result, the lever handle 2 fitted in this part will not be restricted in the vertical direction. The door stopper designed in this way is used for the front door. A diagram showing its use is shown in FIG. Figure 13 is a perspective view of the door stopper alone. Keep the lever handle 2 raised when you close the front door. To stop the entrance door in the half-opened state, turn the lever handle 2 down to the floor and use it. Normally, there is a door closer acting on the entrance door, and the entrance door is forced to close, but when the lever handle 2 is turned over, the above-mentioned action is exerted between the lever handle and the floor surface. The door will stop. If sharp projections 10 are provided in a pair, it is possible to set the stop function of the lever handle 2 from the outside, and an adverse effect can be expected. If the lever handle 2 descends due to mischief or something, the door will not open from the room. In order to prevent such accidents and mischief, one lever handle holding direction switching mechanism 1 was removed. Only when attaching or removing the door stopper to the front door, lever levers are inserted into a pair to facilitate installation and removal operations. Normally, the lever handle on the outside (corridor) side is removed Use it. Industrial applicability

As described above, the door stopper according to the present invention is useful as a stopper for a door, an indoor door, or an entrance door, and it is beautifully embedded in an indoor atmosphere or a landscape and inconspicuous. Suitable for fixing.
