Description

The present invention relates to a shock absorber for a window, and particularly to a shock absorber for a sash window.

A sash window in which a plate-shaped glass or the like is fitted in a sash as a window frame is known. The term "sash" may be used as a general term for a sash as a window frame and glass fitted in the sash. However, in the present specification, "sash" is used as a term meaning only a window frame. When the sash as a window frame and the glass fitted in the sash are generically referred to, the term "sash window" is used.

The basic structure of the conventional sash window will be outlined with reference to FIG. The window 100 shown in FIG. 8 is a "sliding window" composed of two sash windows 101 and 102, each of which can be opened and closed to the left and right. Each of the sash windows 101 and 102 has a sash 104 and a glass 105 fitted in the sash 104, and is attached to an opening 103 provided in the wall W of the building.

The sash 104 is formed in a frame shape by a pair of horizontal frame members 106, 107 facing each other and another pair of vertical frame members 108, 109 facing each other. In the following description, the horizontal frame member 106 may be referred to as the “lower frame member 106”, and the horizontal frame member 107 may be referred to as the “upper frame member 107”. Further, the vertical frame member 108 may be referred to as a "right frame member 108", and the vertical frame member 109 may be referred to as a "left frame member 109". Further, the lower frame material 106, the upper frame material 107, the right frame material 108, and the left frame material 109 may be collectively referred to as "frame material 110".

A rail is provided in the opening 103 to which the sash windows 101 and 102 are attached. Specifically, as shown in FIG. 9, rails 120 (lower rail 120a, upper rail 120b) are provided above and below the opening 103. On the other hand, the lower frame member 106 of the sash 104 is formed with a lower groove 106a that can be engaged with the lower rail 120a, and the upper frame member 107 of the sash 104 is formed with an upper groove 107a that is engageable with the upper rail 120b. Has been done. Further, a roller 121 called a "door wheel" or a "roller" is interposed between the lower frame member 106 (lower groove 106a) of the sash 104 and the lower rail 120a. Although the number of rollers 121 shown in FIG. 9 is one, a plurality of rollers 121 are actually interposed between the lower frame member 106 and the lower rail 120a. Although not shown, the sash window 102 shown in FIG. 8 is attached to the opening 103 by the same attachment structure as the sash window 101.

A clearance is provided between the sash windows 101 and 102 and the rail 120 so that the sash windows 101 and 102 shown in FIGS. 8 and 9 can be opened and closed smoothly. Therefore, when a force is applied to the sash windows 101 and 102, the sash windows 101 and 102 move. For example, when the wind blows on the sash window 101 shown in FIG. 9 from the left side (outdoor side) of the paper surface, the sash window 101 moves to the right side (indoor side) of the paper surface. Then, when the sash window 101 moves significantly toward the indoor side, the sash 104 may collide with the rail 120 or the roller 121. Specifically, the lower frame member 106 may collide with the lower rail 120a or the roller 121, or the upper frame member 107 may collide with the upper rail 120b. Further, if the sash 104 violently collides with the rail 120 or the roller 121, the rail 120 may be distorted or the roller 121 may be damaged.

As described above, the sash window 102 shown in FIG. 8 is attached to the opening 103 by the same attachment structure as the sash window 101 shown in the figure. Therefore, even when a force is applied to the sash window 102, the sash window 102 may move indoors and the sash 104 may collide with the rail 120 or the roller 121.

An object of the present invention is to provide a window cushioning device capable of preventing a collision between a sash and a rail or a roller and alleviating the impact of the collision.

One of the window shock absorbers of the present invention is mounted on a sash window that includes a sash and glass fitted in the sash. The window shock absorber includes a plate material facing one surface of the glass facing indoors via a gap, and a plurality of fixtures for fixing the plate material to the one surface of the glass. Each of the fixtures has a support portion that penetrates the plate material and supports the plate material in a reciprocating manner, a fixing portion that is provided at one end of the support portion and can be attached to and detached from the one surface of the glass, and the support. Includes a regulatory section provided at the other end of the section. Then, when the sash window moves to the indoor side, the plate material fixed to the glass by the fixture moves to the outdoor side between the fixing portion and the restricting portion.

The other one of the window shock absorbers of the present invention is mounted on a sash window that includes a sash and glass fitted in the sash. The window shock absorber includes a plate material facing one surface of the glass facing indoors via a gap, and a plurality of fixtures for fixing the plate material to the one surface of the glass. Each of the fixtures includes a fixture that is removable and elastic on the one side of the glass. Then, when the sash window moves to the indoor side, the plate material fixed to the glass by the fixture moves to the outdoor side with elastic deformation of the fixing portion.

Yet another one of the window shock absorbers of the present invention is mounted on a sash window that includes a sash and glass fitted in the sash. The window shock absorber includes a plate material facing one surface of the glass facing indoors via a gap, and a plurality of fixtures for fixing the plate material to the one surface of the glass. Each said fixture includes a detachable fixing portion on said one side of the glass. Then, when the sash window moves to the indoor side, the plate material fixed to the glass by the fixture is elastically deformed to the outdoor side.

In one aspect of the present invention, the plate material has an area covering two-thirds or more of the one surface of the glass.

In another aspect of the present invention, the position of the fixture with respect to the plate material can be changed.

It is sectional drawing which shows the cross section along AA in FIG.

Next, some embodiments of the window shock absorber of the present invention will be described in detail with reference to the drawings. However, the same reference numerals are used for configurations that are the same as or substantially the same as those already described in the present specification, and in principle, they will not be described again.

(First Embodiment)
As shown in FIG. 1, the window shock absorber 1A according to the present embodiment is attached to the sash windows 101 and 102, respectively. The sash windows 101 and 102 shown in FIG. 1 have the same shape and structure as the sash windows 101 and 102 shown in FIG. Further, the sash windows 101 and 102 shown in FIG. 1 are attached to the opening 103 by the same attachment structure as the attachment structure already described, and form a building window (sliding window) 100.

Hereinafter, the details of the window cushioning device 1A shown in FIG. 1 will be described. However, the two window shock absorbers 1A shown in FIG. 1 have the same configuration. Therefore, while the window shock absorber 1A attached to the sash window 101 will be described in detail, the description of the window shock absorber 1A attached to the sash window 102 will be omitted.

As shown in FIG. 1, the window shock absorber 1A fixes the plate material 10 facing the one surface of the glass 105 fitted in the sash 104 via a gap and the plate material 10 to the one surface of the glass 105 in the opposite state. A plurality of fixtures 20 and a plurality of fixtures 20 are provided.

As shown in FIG. 1, the planar shape of the plate member 10 is rectangular, and fixtures 20 are arranged one by one at the four corners thereof. That is, the window cushioning device 1A according to the present embodiment includes four fixtures 20.

Here, the wall W provided with the opening 103 is the wall of the building, and one surface of the glass 105 shown in the drawing (one surface of the glass 105 facing the plate member 10) faces the inside of the building. There is. Therefore, in the following description, one surface of the illustrated glass 105 may be referred to as an "inner surface 105a", and the other surface opposite to the inner surface 105a may be referred to as an "outer surface 105b" to distinguish them. The outer surface 105b opposite to the inner surface 105a facing indoors faces the outdoors.

As shown in FIG. 2, each fixture 20 includes a rod-shaped support portion 21, a fixing portion 22 provided at one end of the support portion 21, and a regulation portion 23 provided at the other end of the support portion 21. , Including. The fixing portion 22 in the present embodiment is a suction cup made of rubber or synthetic resin that can be adsorbed on the inner surface 105a of the glass 105.

Through holes 11 are formed at the four corners of the plate material 10. The length of the support portion 21 included in each fixture 20 is longer than the thickness of the plate member 10. Each support portion 21 is inserted through the corresponding through hole 11 and penetrates the plate material 10. The shape of the through hole 11, the support portion 21, the fixing portion 22, and the regulating portion 23 in the vertical cross section orthogonal to the paper surface of FIG. 2 is circular. In short, the through hole 11 is a round hole, and the support portion 21 is a round bar. The diameter of the through hole 11 is slightly larger than the diameter of the support portion 21. That is, the support portion 21 is loosely fitted in the through hole 11 provided in the plate member 10. On the other hand, the diameter of the regulating portion 23 is larger than the diameter of the through hole 11. That is, the regulating portion 23 is a retaining (stopper) that regulates the supporting portion 21 so that it does not come out of the through hole 11. As a result, the plate material 10 fixed to the inner surface 105a of the glass 105 by the four fixtures 20 is in the axial direction of the support portion 21 between the fixing portion 22 and the regulating portion 23 in each fixture 20 (FIG. 2). It can reciprocate in the left-right direction of the paper. In other words, the plate member 10 is supported by four fixtures 20 so as to be reciprocating between the indoor side and the outdoor side.

The shapes of the through hole 11, the support portion 21, the fixing portion 22, and the regulating portion 23 in the vertical cross section are not limited to a circle. Further, the size relationship of the diameters of the through hole 11, the support portion 21, and the regulation portion 23 is not limited to the above relationship. For example, the size and shape of the regulating portion 23 can be appropriately changed on the condition that it can function as a stopper for the supporting portion 21.

The window shock absorber 1A having the above configuration prevents the sash 104 from colliding with the rail 120 or the roller 121 as follows, and also alleviates the impact caused by the collision between the sash 104 and the rail 120 or the roller 121.

As shown in FIG. 3, when the sash window 101 moves to the right side (indoor side) by some force (for example, the wind blown on the sash window 101), the plate material 10 supported so as to be able to reciprocate left and right is the sash window. It moves to the left (outdoor side) in relation to 101. On the other hand, as shown in FIG. 4, when the sash window 101 moves to the left side (outdoor side) by some force, the plate material 10 supported so as to be able to reciprocate to the left and right is on the right side (ya) in relation to the sash window 101. Move inward). That is, when the sash window 101 moves to the indoor side or the outdoor side, the plate material 10 included in the window shock absorber 1A moves relative to the moving direction of the sash window 101. In other words, when the sash window 101 moves to the indoor side or the outdoor side, the center of gravity of the plate member 10 is displaced in the direction opposite to the moving direction of the sash window 101. As a result, when a force for moving the sash window 101 to the indoor side or the outdoor side acts on the sash window 101, the force is canceled and the collision between the sash 104 and the rail 120 or the roller 121 is prevented. Further, even if the sash 104 collides with the rail 120 or the roller 121, the impact force thereof is reduced as compared with the case where the window cushioning device 1A provided with the plate member 10 is not attached. That is, the plate member 10 acts as a weight to reduce the impact force. In other words, the plate material 10 functions as a counterweight.

See FIG. 1 again. The size (area) of the plate material 10 included in the window cushioning device 1A can be appropriately selected. However, from the viewpoint of preventing fragments of the glass 105 broken by strong winds or flying objects from scattering indoors, the area of the plate material 10 may be an area that can cover two-thirds or more of the inner surface 105a of the glass 105. preferable.

Further, the fixing portion 22 shown in FIG. 2 and the like is a suction cup that can be attracted to the inner surface 105a of the glass 105. That is, the fixing portion 22 can be attached to and detached from the inner surface 105a of the glass 105. Therefore, the window shock absorber 1A shown in FIG. 1 can be attached to the sash windows 101 and 102 shown in the same figure when necessary such as in strong winds, and when not needed, the sash windows 101 and 102. Can be removed from. However, the window cushioning device 1A may be permanently installed.

(Second Embodiment)
Next, another example of the embodiment of the window cushioning device of the present invention will be described. However, the window shock absorber according to the present embodiment is common to many parts of the window shock absorber 1A according to the first embodiment. Therefore, while the differences between the window shock absorber according to the present embodiment and the window shock absorber 1A according to the first embodiment will be described, the common points will be omitted as appropriate. Further, the same reference numerals and names are used for the same or substantially the same configuration as that of the window shock absorber 1A according to the first embodiment.

As shown in FIG. 5, the window shock absorber 1B according to the present embodiment has a plate material 10 facing the inner surface 105a of the glass 105 fitted in the sash 104, and the plate material 10 facing the inner surface 105a of the glass 105. It is provided with four fixtures 20 for fixing in a state.

Each fixture 20 includes a fixture 22 that is removable and elastic on the inner surface 105a of the glass 105. The fixing portion 22 in the present embodiment is a suction cup made of rubber or synthetic resin that can be adsorbed on the inner surface 105a of the glass 105. Although there are only two fixtures 20 shown in FIG. 5, in reality, one fixture 20 is arranged at each of the four corners of the plate member 10.

As shown in FIG. 5, the suction cup as the fixing portion 22 has a flat front surface (adsorption surface) that adsorbs to the inner surface 105a of the glass 105 and a curved back surface that is located on the opposite side to the front surface, and has a back surface. The top of the plate is fixed to the plate material 10. Therefore, when the window shock absorber 1B is attached to the sash window 101, the fixing portion 22 is sandwiched between the glass 105 and the plate material 10. In other words, when the window cushioning device 1B is attached to the sash window 101, elastic bodies are arranged between the four corners of the glass 105 and the four corners of the plate member 10. Further, the front surface of the fixed portion 22 which is an elastic body is in contact with the glass 105, and the back surface of the fixed portion 22 which is an elastic body is in contact with the plate material 10.

Therefore, when the sash window 101 shown in FIG. 5 moves to the right side (indoor side), the fixing portion 22 interposed between the glass 105 and the plate material 10 is compressed and elastically deformed (contracted). As a result, the plate material 10 moves to the left side (outdoor side) in relation to the sash window 101. After that, the elastic restoring force of the fixing portion 22 pushes the sash window 101 to the left side (outdoor side) and the plate member 10 to the right side (indoor side). As a result, the plate material 10 moves to the right side (indoor side) in relation to the sash window 101. That is, when the sash window 101 moves to the indoor side or the outdoor side, the plate material 10 included in the window shock absorber 1B moves relative to the moving direction of the sash window 101. In other words, when the sash window 101 moves to the indoor side or the outdoor side, the center of gravity of the plate member 10 is displaced in the direction opposite to the moving direction of the sash window 101.

As described above, by attaching the window shock absorber 1B to the sash window 101, the collision between the sash 104 and the rail 120 or the roller 121 is prevented, and the impact due to the collision between the sash 104 and the rail 120 or the roller 121 is alleviated. NS.

(Third Embodiment)
Next, another example of the embodiment of the window cushioning device of the present invention will be described. However, the window shock absorber according to the present embodiment is common to many parts of the window shock absorber 1B according to the second embodiment. Therefore, while the differences between the window shock absorber according to the present embodiment and the window shock absorber 1B according to the second embodiment will be described, the common points will be omitted as appropriate. Further, the same reference numerals and names are used for the same or substantially the same configuration as that of the window shock absorber 1B according to the second embodiment.

As shown in FIG. 6, the window shock absorber 1C according to the present embodiment has a plate material 10 facing the inner surface 105a of the glass 105 fitted in the sash 104, and the plate material 10 facing the inner surface 105a of the glass 105. It is provided with four fixtures 20 for fixing in a state.

Each fixture 20 includes a detachable fixture 22 on the inner surface 105a of the glass 105. The fixing portion 22 in the present embodiment is a suction cup made of rubber or synthetic resin that can be adsorbed on the inner surface 105a of the glass 105. Although there are only two fixtures 20 shown in FIG. 6, in reality, one fixture 20 is arranged at each of the four corners of the plate member 10. Therefore, when the window shock absorber 1C is attached to the sash window 101, the four corners of the plate material 10 are fixed to the four corners of the glass 105, respectively. On the other hand, the plate material 10 provided in the window cushioning device 1C according to the present embodiment is thinner and more elastic than the plate material 10 (FIG. 5) provided in the window cushioning device 1B according to the second embodiment. As a result, when the sash window 101 including the glass 105 to which the four corners of the plate material 10 are fixed moves, the plate material 10 elastically deforms as the sash window 101 moves.

Specifically, as shown in FIG. 7A, when the sash window 101 moves to the right side (indoor side), the plate member 10 elastically deforms to the left side (outdoor side). More specifically, the plate material 10 is elastically deformed so that the central portion farthest from the fixed point with respect to the glass 105 is closest to the glass 105. On the other hand, as shown in FIG. 7B, when the sash window 101 moves to the left side (outdoor side), the plate member 10 elastically deforms to the right side (indoor side). More specifically, the plate material 10 is elastically deformed so that the central portion farthest from the fixed point with respect to the glass 105 is the most distant from the glass 105. That is, when the sash window 101 moves to the indoor side or the outdoor side, at least a part of the plate material 10 included in the window shock absorber 1C moves relative to the moving direction of the sash window 101. As a result, when the sash window 101 moves to the indoor side or the outdoor side, the center of gravity of the plate member 10 is displaced in the direction opposite to the moving direction of the sash window 101.

As described above, by attaching the window shock absorber 1C to the sash window 101, the collision between the sash 104 and the rail 120 or the roller 121 is prevented, and the impact due to the collision between the sash 104 and the rail 120 or the roller 121 is alleviated. NS.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist thereof. For example, the material, shape, size, thickness, weight, etc. of the plate material included in the window shock absorber of the present invention can be appropriately changed as needed. Examples of the material for forming the plate material include wood, acrylic resin, vinyl chloride resin, and paper. Further, the plate material may be formed from one kind of material, or the plate material may be formed from two or more kinds of materials. Further, the plate material may have a single-layer structure or a multi-layer structure. When the plate material has a multi-layer structure, each layer may be formed of the same kind of material or may be made of different materials.

The window cushioning device of the present invention can be installed not only indoors but also outdoors. For example, the window shock absorber of the present invention can be mounted on the outer surface 105b of the glass 105 shown in FIG. 2 and the like. If the window shock absorber of the present invention is installed outdoors, it is possible to prevent the glass from being damaged by flying objects. Further, the window shock absorber of the present invention can also be attached to a window provided on a partition wall or the like in a building. For example, if the window shock absorber of the present invention is attached to the sash window provided on the partition wall that separates two rooms having a pressure difference, collision between the sash and the rail or roller can be prevented or collision can occur. The effect of cushioning the impact can be expected.

The fixing portion included in the fixing tool of the window shock absorber of the present invention is not limited to a suction cup as long as it can realize a fixing tool that enables the plate material to be attached to and removed from the sash window. Further, the number of fixtures included in the window shock absorber of the present invention can be appropriately changed as needed. Further, the position of the fixture with respect to the plate material can be changed. In this case, the positions of all the fixtures may be changeable, or only the positions of some fixtures may be changeable. For example, the plate material 10 included in the window shock absorber 1A according to the first embodiment is provided with four through holes 11, but the position of the fixture 20 with respect to the plate material 10 is changed by adding the through holes 11. It can be possible. By making it possible to change the position of the fixture with respect to the plate material, a window shock absorber that can be attached to a sash window smaller than the plate material is realized. Further, by changing the position of the fixture with respect to the plate material, a window shock absorber capable of changing or adjusting the behavior characteristics of the plate material is realized.
