Description

[Detailed explanation of the idea] The present invention relates to a doorstop with great soundproofing effect.

In order to improve the soundproofing performance of a door, in addition to the soundproofing performance of the door itself, it is also important to ensure that the door and the doorstop are airtight. Conventionally, as a means for improving this airtightness, a method of sealing with a doorstop using magnetic rubber is known. However, this kind of door stop is not only heavy because it opens the door against magnetic force, but also has low sound absorption performance despite its high cost, making it insufficient for sound insulation, especially at high temperatures. The reality is that satisfactory results have not been obtained.

The present invention provides a door stop with excellent soundproofing effects.The door stop is constructed with upper and lower members that are removably locked, and the hollow space formed by these members is filled with sound-absorbing material. improve the
In particular, the aim is to improve sound insulation against high temperatures.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the door stop has a lower member 3 attached to the frame 2 of the opening to which the door 1 is attached, and an upper member 4 that is removably secured to the lower member by fitting or screwing, for example. A door receiving portion 9 is provided at the front portion of the upper member 4 against which the door comes into contact. In this case, the door receiving portion 9 is usually formed of an elastic member so as to provide airtightness and a cushioning effect with respect to the door.

It is preferable that the lower member 3 is attached to the frame frame 2 with screws 6 using loosely fitting screw holes 6. Such a mounting structure is effective for adjusting the adhesion between the door 1 and the door receiving part 9 of the door stop to be good.
The position of the door stop is adjusted within the range of the loose fit screw hole 6 in accordance with the surface around the door that the door receiver comes into contact with.
Such adjustments can be made as appropriate by removing the upper member 4 not only during initial installation but also when the door surface is deformed during use.

Further, a rising portion 8 is formed on the door side of the lower member 3, and when the upper member 4 is locked, a hollow portion 10 is formed between the two. is filled with sound absorbing material 11. The rising portion 8 is provided with an opening 5 communicating with the hollow portion 10 along the door receiving portion 9 of the door stop,
The sound absorbing material 11 is designed to increase the sound absorbing effect. Note that, although glass wool is suitable as the sound absorbing material 11, it is not particularly limited thereto. Further, the shape and size of the opening 5 can be selected as appropriate; for example, it may be formed into a slit shape, and if the opening 5 is formed relatively large, the sound absorbing material 11 may be hidden. A cover may be provided for this purpose. Furthermore, the rising portion 8 is shown in the figure.
Although the case is shown in which it is provided on the lower member side, it can also be provided on the upper member 4.

Since the door stop according to the present invention is constructed as described above, after attaching the lower member 3 to the frame 2, the sound absorbing material 11 is loaded into the hollow part 10 and the upper member 4 is attached from above. It is easy to obtain, and the above-mentioned sound absorbing material not only provides a soundproofing effect, especially in the high frequency range, which cannot be obtained sufficiently with conventional doorstops, but also because the door is sealed by simply pressing it against the doorstop. , easy to open and close.

Furthermore, the door stop is constructed by combining upper and lower members,
By screwing this lower member to the frame frame using loose-fitting screw holes, the door stop can be easily adjusted to match the door surface at any time, maintaining good adhesion between the door and the door stop. be able to.

[Brief explanation of the drawing]

FIG. 1 is a sectional view of a door stop according to an embodiment of the present invention, and FIG. 2 is an enlarged perspective view of its lower member. In the figure, 1 is a door, 2 is a frame, 3 is a lower member, 4 is an upper member, 10 is a hollow part, and 11 is a sound absorbing material.
