Abstract

<P>PROBLEM TO BE SOLVED: To provide a window having a window frame which instantaneously exhibits damping effect and prevents impact sound from occurring and which enables the simplification of working steps during the installation. <P>SOLUTION: This window includes an upper frame (window frame member) 1, generally wedge-shaped through members 2a, 2b having respective cross sections convergent to the outdoor side, damping members 3a, 3b attached to both sides of the depth surface of the through members, respectively, and bolts (pressing means) 4a, 4b. The upper frame includes generally wedge-shaped hollow sections 5a, 5b into which the through members are inserted, respectively. The bolts press the through members to the outdoor side of the upper frame, respectively. The damping members are pressed against the depth surface of the upper frame and the depth surfaces of the through members. Since the through members and the damping members are installed on the upper frame, the mass of the upper frame is increased, and since the damping members are pressed against the upper frame by the through members, a tension is applied to the upper frame and the rigidity of the upper frame is increased. Therefore, the vibration of the upper frame is suppressed, and the noise thereof is reduced. Since the vibration is suppressed by increasing the mass and the rigidity of the upper frame, much time is not required by a time when the damping effect is exhibited. Since a movable part is absent, sound is not produced by opening and closing the window. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a window in which a vibration-proof measure is taken on a window frame.

Noise entering the room through the window includes not only sound entering through the window glass but also sound entering through the window frame. In particular, when a ventilation duct is provided in the window frame, noise that passes through the duct and enters the room through the window frame becomes a serious problem. As a countermeasure, conventionally, a filler such as sand is filled in a hollow window frame, but the workability is very bad. In order to improve such poor workability, for example, in Patent Document 1, a housing having a hollow portion fixed to a window frame, a mass member movably accommodated in the housing, a surface of the mass member, or a housing And an elastic body disposed on one of the inner surfaces. When the window frame vibrates, the mass member moves and collides with the inner surface of the housing via the elastic body, and the vibration is attenuated by energy loss at the time of the collision. A vibration device has been proposed.
JP 2002-206375 A

  However, the invention of Document 1 is that the mass member and the housing collide with each other due to the vibration of the window frame to exert a damping effect, so that it is considered that a certain time is required until the anti-vibration effect is exhibited, In addition, there is a problem that the mass member may move when the window is opened and closed to generate a collision sound.

  The present invention has been made in view of the above circumstances, and includes a window frame that immediately exhibits an anti-vibration effect and does not generate a collision sound and the like, and further provides a window with a simple work process during construction. Objective.

  The invention of claim 1 of the present invention comprises a window frame material, a through member, a vibration isolating material, and a pressing means, and the window frame material has a hollow portion into which the through member is inserted. Is positioned on the inner peripheral side of the window frame member and on the outer peripheral side of the through member, the pressing means presses the through member against the inner peripheral surface of the window frame member, and the vibration isolator is connected to the inner peripheral surface of the window frame member and the through member. It is characterized by being in pressure contact with the outer peripheral surface.

  The invention of claim 2 of the present invention is that the hollow portion of the window frame member and the through member are substantially wedge-shaped with a cross-section narrowing toward the outdoor side, and the vibration isolator is provided on both sides of the through surface of the through member, The pressing means presses the through member against the outdoor side of the window frame member, and the vibration isolator presses between the expected surface of the window frame member and the expected surface of the through member.

  According to the first aspect of the present invention, since the through member and the vibration isolating material are provided in the window frame material, the mass of the window frame itself is increased, and the vibration isolating material is pressed against the window frame material by the through member. Therefore, tension is applied to the window frame material and the rigidity of the window frame material is increased, so that the window frame is less likely to vibrate, and noise entering through the window frame is reduced. Since vibration is suppressed by increasing the mass and rigidity of the window frame itself, it does not take time to exhibit the anti-vibration effect, and there is no moving part, so no sound is generated by opening and closing the window etc. . Further, the window frame material only needs to have a hollow portion, and can be attached to an existing window frame material by appropriately setting the shape of the through member and the vibration isolating material, and the workability is also good.

  According to the invention of claim 2 of the present invention, since both the hollow portion of the window frame material and the through member are substantially wedge-shaped, the vibration isolating material is widely pressed against both prospective surfaces of the window frame material and is higher. Provides anti-vibration effect. In particular, since the vibration of the expected surface with which the vibration isolator is in contact is suppressed, if the present invention is applied to a window having a duct outside the expected surface of the window frame material, a high noise reduction effect is exhibited. In addition, the workability is very good because the vibration isolator is provided in the through member and inserted into the window frame member.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 3, the window of the present invention is a fitting window in which glass 63 is fitted in a frame body in which an upper frame 1, a lower frame 60, a left vertical frame 61 and a right vertical frame 62 are framed in four directions. The front side of the paper is the outdoor side, and the back side of the paper is the indoor side. Upper frame 1
Is a hollow structure having a substantially rectangular cross section composed of an upper side surface 11, a lower side surface 12, an outdoor side surface 13 and an indoor side surface 14, as shown in FIG. A glass attachment portion 17 extends from the outdoor side surface 13 and a glass 63 is attached. A ventilation duct 70 is connected above the intermediate expected surface 15 of the indoor side surface 14, and an opening is provided above the intermediate expected surface 15 of the outdoor side surface 13 as a duct inlet 71. Are communicating. A duct cover 72 for preventing raindrops from entering is provided on the front surface of the duct inlet 71. The intermediate expected surface 15 is inclined downward toward the outdoor side, and a rib 16 is formed between the outdoor expected surface 15 and the lower side surface 12 between the outdoor side surface 13 and the indoor side surface 14. The intermediate prospective surface 15, the lower side surface 12, the outdoor side surface 13 and the rib 16, and the intermediate prospective surface 15, the lower side surface 12, the rib 16 and the indoor side surface 14 form two substantially wedge-shaped hollow portions 5 a and 5 b. In such a window, there is a problem that outdoor noise enters from the duct inlet 71 and is transmitted from the intermediate expected surface 15 of the upper frame 1 to the lower side surface 12 and enters the indoor side (see “Sound in FIG. 1”). Entry route "). Therefore, the hollow portions 5a and 5b are provided with through members 2a and 2b for vibration isolation, vibration isolation materials 3a and 3b, and bolts (pressing means) 4a and 4b, respectively. To do.

As shown in FIG. 2, the through members 2a and 2b are substantially similar in cross-section to the hollow portions 5a and 5b, respectively, and fitting grooves 21a and 22a and 21b and 22b are formed on both prospective surfaces, respectively. is there. The anti-vibration materials 3a and 3b have a substantially U-shaped cross section and open to the indoor side, and protrusions 31a and 32a and 31b and 32b are formed inside the upper and lower surfaces. The anti-vibration materials 3a and 3b cover the outdoor sides of the through members 2a and 2b, and the protrusions 31a, 32a and 31b and 32b are fitted and fixed in the fitting grooves 21a, 22a and 21b and 22b. The bolts 4a and 4b are screwed into the screw holes formed in the ribs 16 or the indoor side surface 14 from the indoor side, and their tips abut against the through members 2a and 2b to press the through members 2a and 2b toward the outdoor side. The anti-vibration materials 3a and 3b are in pressure contact with both the expected surfaces of the through members 2a and 2b and the intermediate expected surface 15 and the lower side surface 12 of the upper frame 1. The upper frame 1 and the through members 2a and 2b are extruded products made of aluminum, and the vibration isolators 3a and 3b are made of rubber.
If comprised in this way, since the through-members 2a and 2b and the vibration isolator 3a and 3b were provided in the upper frame 1, the mass of the whole window frame will increase, and the anti-vibration materials 3a and 3b are expected to be intermediate to the upper frame 1. Since the upper frame 1 is pressed against the surface 15 and the lower side surface 12, tension is applied to the upper frame 1 to increase the rigidity of the upper frame 1, the upper frame 1 is less likely to vibrate, and noise entering through the upper frame 1 is reduced. The intermediate anticipation surface 15 and the lower side surface 12 of the upper frame 1 to which the vibration isolating materials 3a and 3b are widely in pressure contact have a particularly high anti-vibration effect and can effectively reduce the sound entering from the duct inlet 71. Further, since the mass and rigidity of the window frame itself are increased as described above, and the movable frame is not included, the anti-vibration effect is immediately exhibited and the structure does not become a new sound source. Furthermore, in the construction, first, the vibration isolators 3a and 3b are fixed to the passing members 2a and 2b, inserted into the hollow portions 5a and 5b, and pressed by the bolts 4a and 4b. The workability is very good compared with the method of packing the filler.

  Next, the result of the experiment which confirmed the soundproofing effect of the window of this invention is shown. In this experiment, the sound transmission loss for each 1/3 octave band was measured for each of the window of the present invention and a conventional window not provided with a through member or a vibration isolator. The sound transmission loss represents a sound pressure level difference between the incident sound and the transmitted sound, and the soundproof performance is higher as the sound transmission loss is larger. FIG. 4 is a graph showing the results, and the sound transmission loss of the window of the present invention is larger over almost the entire region of 1000 Hz to 5000 Hz. In particular, the difference is large in the vicinity of 3000 Hz to 4000 Hz where the human ear is most sensitive, and the maximum is 7 dB. It was confirmed that the window of the present invention has higher soundproofing performance than the conventional window. .

  The present invention is not limited to the above embodiment. For example, there may be no rib or a plurality of ribs. When there are no ribs, one through member, vibration isolator and pressing member may be provided. When a plurality of ribs are provided, the number of through members, vibration isolator and pressing members increases according to the number of ribs. Moreover, the cross-sectional shape of the hollow part of a window frame material and a through member is not restricted to the substantially wedge shape like an Example. For example, the hollow portion and the through member may be rectangular and may be pressed upward from below by pressing means. The pressing means may be anything as long as it can press the threading member against the window frame material, and the elastic member such as a spring or the like is provided with an elastic member such as a spring that tightens the threading member and the window frame material. It may be pressed by force. The place where the vibration isolator is provided is also free and may be in pressure contact with the finding surface instead of the expected surface. Furthermore, although the through member and the vibration isolating material are provided in the upper frame in the embodiment, they may be provided in the lower frame and the left and right vertical frames. The material of the window frame material and the through member may be any material as long as it is generally used as a building material, and the material of the vibration isolator may be a urethane material, a gel material, or the like in addition to rubber.

FIG. 4 is a sectional view taken along line AA in FIG. 3. It is an enlarged view of the upper frame part of FIG. It is the outdoor side front view of the window of this invention. It is the graph which compared the sound transmission loss of the window of this invention, and the conventional window.
