Description

  The present invention relates to a door set and a ventilator. More specifically, the present invention relates to a door set and a ventilation device having a ventilation function for switching an airtight ventilation state.

  Recent residential buildings have adopted a structure that reduces the influence of the external climate on the indoor environment for the purpose of improving the living environment. For example, structures that can achieve high heat insulation, high airtightness, and sound insulation have become common.

  In such a building, natural ventilation inside the building (in the room) can hardly be expected, so facilities and mechanisms for ventilation can be provided on the building itself or its doors, etc. so that the room can be ventilated. It is necessary to.

  Conventionally, as a method of ventilating a room, a door is provided with a ventilation mechanism. Specifically, glazing windows are provided on the inner surface and the outer surface of the door, respectively, and a ventilation passage that communicates between the glazing windows is provided in the door.

Further, Patent Document 1 discloses a door device that can maintain indoor airtightness and is provided with a ventilation function.
This Patent Document 1 discloses a door device including a ventilation path that communicates between the surfaces of a door, a shielding member that blocks or opens the ventilation path, and an operation unit that operates the shielding member. In the case of this door device, the airtightness can be maintained by operating the shielding member by the operation unit to block the air passage. On the contrary, if the air passage is opened by operating the shielding member with the operation portion, the air can be secured through the air passage.

According to a tenth aspect of the present invention, in the sixth, seventh, eighth or ninth aspect, the shielding member is a cushion material used as a door stop of the door frame.

According to the first invention, the ventilation state and the shielding state can be switched by moving the shielding member of the ventilation mechanism close to and away from the door. In addition, since the ventilation mechanism is provided on the door frame, and only the shielding member is moved close to and away from the door, no special processing or the like is required on the door itself. Therefore, even if a ventilation mechanism is provided, it is possible to prevent the door structure from becoming complicated.
According to the second aspect of the present invention, the shielding member can be moved closer to and away from the door simply by moving the moving member along the surface direction of the door frame. And since the operation part which has a moving member is only provided between the shielding member and the door stop of a door frame, the structure of a ventilation mechanism can be made simple.
According to the third aspect of the invention, since the movable side member is moved by being guided by the guide mechanism, the movement of the shielding member can be stabilized.

In other words, the gap can be cut off without changing the structure of a building or an object. For example, if the door frame of the door set and the gap between the door are cut off, if the ventilation device is attached to the door frame so that the opening of the case faces the door, and the amount of protrusion of the shielding member is changed, The shielding member can be moved closer to and away from the door. That is, in the case of a door set, the ventilation state and the shielding state can be switched by attaching the ventilation device to the door frame. In addition, in the case of a door set, only a ventilation device is attached to the door frame, so that a ventilation function can be easily added to an existing door set or the like.
According to the seventh aspect of the present invention, the amount of protrusion of the shielding member can be changed simply by moving the moving member along the opposing inner surface.
According to the eighth aspect of the invention, since the movable side member is guided by the guide mechanism, the movement of the shielding member can be stabilized.
According to the ninth aspect, since the movable side member is guided by the guide mechanism, the movement of the shielding member can be stabilized.
According to the tenth aspect, since the shielding member is a cushion material, the shielding effect by the ventilation device can be enhanced. For example, when the ventilation device is attached to the door frame, the airtightness when the gap between the door frame and the door is shielded can be increased.

The door frame 2 is provided with the respective frames 2a to 2d so that an opening 2h having a substantially rectangular shape in front view surrounded by a pair of frame frames 2a and 2b, a lower frame 2c, and an upper frame 2d is formed. .

  Each frame 2a-2d of the door frame 2 is provided with a door stop ds, and a cushion P is attached to the door stop ds (see FIG. 1). That is, the cushion P is disposed in the door contact ds of each of the frames 2a to 2d so as to surround the opening 2h of the door frame 2. The cushion P is provided to absorb an impact when the door 10 is closed and to maintain airtightness between the door frame 2 and the door 10. Accordingly, the cushion P is provided so as to come into contact with the surface of the door 10 (the indoor-side surface 10a) when the door 10 is closed.

(Door 10)
As shown in FIG. 3, a door 10 is attached to the door frame 2. The door 10 is substantially similar to the opening 2h of the door frame 2, and is formed in a size that can close the opening 2h of the door frame 2 when the door 10 is closed.

The door 10 is slidably connected to the door frame 2 by a connecting means. Specifically, the door 10 swings horizontally with its door butt (left end in FIGS. 1 and 3B) as a fulcrum, and the door tip (right end in FIG. 3B) horizontally. It connects with the door frame 2 by the connection means so that it can do.
The connecting means is not particularly limited as long as it has the above function. For example, a known hinge, pivot hinge, floor hinge, or the like can be used as the connecting means of the door set 1 of the present embodiment.

(Ventilation mechanism 20)
As shown in FIG. 1, in the door set 1 of the present embodiment, a ventilation mechanism 20 is provided on the heel frame 2b on the door bottom side. The ventilation mechanism 20 includes a cushion P and an operation unit 21 having a function of moving the cushion P. In the ventilation mechanism 20, the operating mechanism 25 of the operating portion 21 that moves the cushion P is provided on the inner surface (surface that forms the opening 2h) of the collar frame 2b (see FIG. 7). By operating the operating lever 25r of the operating mechanism 25, the protruding amount of the cushion P (in other words, the distance between the cushion P and the surface 10a of the door 10 when the door 10 is closed) can be adjusted. It has become. In other words, when the operating lever 25r of the operating mechanism 25 is operated with the door 10 closed, the cushion P is in contact with the surface 10a of the door 10 (shielded state) and between the cushion P and the surface 10a of the door 10 The cushion P can be moved in a state where there is a gap (ventilation state). Details of the ventilation mechanism 20 will be described later.

  Since it is the above structure, according to the door set 1 of this embodiment, if the door 10 is closed, the room | chamber interior and the outdoor can be isolate | separated almost airtightly, On the other hand, it ventilates in the state which closed the door 10. Can do.

  Specifically, the operation lever 25r of the operation mechanism 25 is operated so that the cushion P provided on the collar frame 2b is in contact with the surface 10a of the door 10 with the door 10 of the door set 1 closed. deep. Then, if the door 10 of the door set 1 is closed, all of the cushions P provided on the frames 2a to 2d of the door frame 2 can be brought into contact with the surface 10a of the door 10 (shielded state). Therefore, the gap between the door contact ds of each door frame 2 a to 2 d of the door frame 2 and the surface 10 a of the door 10 can be closed by the cushion P. And since the cushion P provided in each frame 2a-2d is provided so that the opening 2h of the door frame 2 may be enclosed, if the door 10 is closed, it will close the opening 2h of the door frame 2 almost airtightly. (See FIG. 2A).

  On the other hand, by operating the operating lever 25r of the operating mechanism 25, the cushion P provided on the collar frame 2b is moved away from the surface 10a of the door 10 with the door 10 of the door set 1 closed. Then, even when the door 10 of the door set 1 is closed, a state in which a gap is formed between the cushion P provided on the collar frame 2b and the surface 10a of the door 10 (ventilation state) can be achieved. Therefore, since the room and the outside can be ventilated through the gap between the frame 2b and the door 10, ventilation can be performed with the door 10 closed (see FIG. 2B). ).

  In FIG. 1 and FIG. 2, the filter G is provided between the door bottom of the door 10 and the gutter frame 2b. However, the filter G is not necessarily provided. However, if the filter G is provided, there is an advantage that dust or the like can be prevented from entering the room when the ventilation state is established.

(Description of ventilation mechanism 20)
Next, the ventilation mechanism 20 will be described in detail.
As shown in FIG. 1 to FIG. 3, a ventilation mechanism 20 is provided in the heel frame 2 b on the door bottom side. Specifically, a storage groove 2g for storing the ventilation mechanism 20 is usually provided in the heel frame 2b on the door bottom side at a position where the cushion P is disposed in the door contact ds. The housing groove 2g is a groove extending along the axial direction of the heel frame 2b on the door bottom side (that is, the vertical direction of the door frame 2). A ventilation mechanism 20 is provided in the housing groove 2g.

  As shown in FIG. 1, the ventilation mechanism 20 includes a case 20a. The case 20a is a long member formed in a substantially U-shaped cross section. The case 20a is attached to the housing groove 2g so that the outer surface of the bottom wall faces the inner bottom surface s of the housing groove 2g and the inner surface of the bottom wall is substantially parallel to the door stop ds.

The case 20a includes a cushion P corresponding to a shielding member in the scope of the claims, and an operation unit 21 that causes the cushion P to protrude and retract from the opening of the case 20a.
In addition, since the opening of the case 20a faces the door 10 side, similarly to the opening of the housing groove 2g, if the cushion P is made to appear and disappear from the opening of the case 20a, the cushion P is in relation to the surface 10a of the door 10. It will approach and separate.

  The cushion P extends along the axial direction of the case 20a, that is, along the axial direction of the housing groove 2g. The back of the cushion P is attached to the support plate SP. Specifically, the support plate SP is a long member having a substantially U-shaped cross section, and the back portion of the cushion P is inserted into the groove of the support plate SP.

  A mechanism (cushion guide mechanism PA) for guiding the movement of the support plate SP (that is, the movement of the cushion P) is provided between the support plate SP and the inner surface of the bottom wall of the case 20a (see FIGS. 4 and 5). ). The cushion guide mechanism PA includes a shaft member erected on the back surface of the support plate SP and a cylindrical member erected on the inner surface of the bottom wall of the case 20a. Has been inserted. Therefore, the support plate SP can be moved in the direction approaching and separating from the inner surface of the bottom wall of the case 20a (that is, the inner bottom surface s of the housing groove 2g) by the cushion guide mechanism PA, but the axial direction of the case 20a (that is, housing) It is connected to the inner surface of the bottom wall of the case 20a (that is, the inner bottom surface s of the housing groove 2g) so as not to move in the axial direction of the groove 2g.

(Operation unit 21)
As shown in FIGS. 1 and 7, the operation unit 21 is provided between the back surface of the support plate SP that supports the cushion P (that is, the back surface of the cushion P) and the inner surface of the bottom wall of the case 20a. The operation unit 21 includes a moving plate 21a, a guide mechanism 22, and an operating mechanism 25. The moving plate 21a corresponds to the moving member in the claims.

(Moving plate 21a)
As shown in FIG. 1, the moving plate 21a is a plate-like member, and is disposed near the bottom wall of the case 20a. The moving plate 21a is disposed so that the surface thereof is parallel to the inner surface of the bottom wall of the case 20a (that is, the inner bottom surface s of the housing groove 2g). The moving plate 21a is provided so as to be movable in the axial direction of the case 20a along the inner surface of the bottom wall of the case 20a (in other words, along the surface of the door stop ds). The moving plate 21a is moved by an operating mechanism 25 described later, details of which will be described later.

  The moving plate 21a is formed with a through hole h penetrating the front and back. The through hole h is a long hole extending in the axial direction of the moving plate 21a, and the cushion guide mechanism PA described above is disposed in the through hole h (see FIG. 4).

(Guiding mechanism 22)
As shown in FIGS. 4 and 5, the guide mechanism 22 includes a plurality of movable side members 23 connected to the back surface of the support plate SP, and a plurality of guide portions 24 provided on the moving plate 21a. Yes.

  As shown in FIGS. 4-6, the several movable side member 23 is a member formed in the cross-sectional substantially U shape, and is provided at intervals along the axial direction of support plate SP. Each movable member 23 has a bottom wall 23a fixed to the back surface of the support plate SP, and a guide groove 23g is formed on a side wall 23b thereof (a side wall 23b erected on the back surface of the support plate SP) (FIG. 5 and FIG. 6). The guide groove 23g is provided so as to be inclined with respect to the surface of the moving plate 21a. More specifically, the guide groove 23g has a distance from the bottom wall 23a that decreases from the base end (lower end in FIG. 5) to the front end (upper end in FIG. 5). Is provided. In other words, the guide groove 23g is inclined with respect to the inner surface of the bottom wall of the case 20a (that is, the inner bottom surface s of the housing groove 2g), and the inner surface of the bottom wall of the case 20a increases from the base end toward the tip. It is arrange | positioned so that the distance from may become long.

  Moreover, the some guide part 24 is provided at intervals along the axial direction of the movement plate 21a. And each guide part 24 is provided in the position corresponding to the several movable side member 23 mentioned above. Each guide portion 24 includes a base material 24a whose base end is fixed to the surface of the moving plate 21a, and a guide member 24b provided at the front end of the base material 24a. The guide member 24 b is a shaft-shaped member, and the tip thereof is inserted into the guide groove 23 g of the movable side member 23.

  Since the guide mechanism 22 is configured as described above, the cushion P can be moved toward and away from the inner surface of the bottom wall of the case 20a by moving the moving plate 21a.

  That is, if the moving plate 21a is moved along the bottom wall inner surface of the case 20a, the guide members 24b of the plurality of guide portions 24 can also be moved along the bottom wall inner surface of the case 20a. The guide member 24b is inserted into the guide groove 23g of the movable member 23, and the guide groove 23g is inclined with respect to the inner surface of the bottom wall of the case 20a. For this reason, when the guide member 24 b of the guide portion 24 moves along the inner surface of the bottom wall of the case 20 a, the guide member 24 b interferes with the movable side member 23. Then, a force for moving the movable member 23 from the guide member 24b along the inner surface of the bottom wall of the case 20a is applied. However, the support plate SP to which the movable member 23 is attached is connected to the inner surface of the bottom wall of the case 20a so as not to move in the axial direction of the case 20a by the cushion guide mechanism PA. On the other hand, the guide groove 23g is inclined with respect to the inner surface of the bottom wall of the case 20a. For this reason, the movable side member 23 moves in the direction approaching and separating from the bottom wall inner surface of the case 20a by the force applied to the movable side member 23 from the guide member 24b. Therefore, if the moving plate 21a is moved along the bottom wall inner surface of the case 20a, the cushion P is moved closer to and away from the inner surface of the bottom wall of the case 20a together with the support plate SP to which the movable member 23 is connected. It can be moved.

(Operating mechanism 25)
As shown in FIG. 7, the side wall (the side wall of the housing groove 2g) that forms the housing groove 2g in the collar frame 2b, and the side wall of the case 20a have mounting holes hb that communicate between the housing groove 2g and the outside. And the attachment hole 20h which connects between the side wall of case 20a and the exterior is provided. And the operating mechanism 25 which has a French dropping mechanism is attached to the attachment hole hb of the side wall of the accommodation groove 2g. The operating mechanism 25 is provided such that when the operating lever 25r is operated, the moving plate 21a moves in the axial direction, that is, in the direction along the inner surface of the bottom wall of the case 20a.

  Specifically, as shown in FIG. 5, the moving plate 21a is provided with a plate 21p orthogonal to the surface thereof. On the lower surface of the plate 21p, a tip of a pin 25p connected to the operating lever 25r is provided so as to contact. Therefore, if the operating lever 25r is swung upward, the pin 25p moves downward, so that the movable plate 21a can be moved downward along the inner surface of the bottom wall of the case 20a (FIG. 5A). ). On the other hand, if the operating lever 25r is swung downward, the pin 25p moves upward, so that the movable plate 21a can be moved upward along the inner surface of the bottom wall of the case 20a together with the plate 21p (FIG. 5 (B)).

  Since the operation unit 21 is configured as described above, the cushion P can be moved between the shielded state and the ventilated state by operating as follows. Therefore, with the door 10 of the door set 1 of the present embodiment closed, it is possible to switch between a state in which the room and the outside are separated from each other almost airtight and a state in which the room and the room are in communication (a state in which ventilation is possible).

  First, when the room and the outdoor are separated from each other in a substantially airtight manner, the operating lever 25r of the operating mechanism 25 is operated to swing the operating lever 25r upward (see FIG. 5A). Then, since the moving plate 21a moves downward, it is guided by the guide mechanism 22, and the cushion P moves away from the inner surface of the bottom wall of the case 20a (that is, the inner bottom surface s of the housing groove 2g). Then, the cushion P can be protruded from the opening of the case 20a (that is, the opening of the housing groove 2g). Therefore, when the door 10 is closed, the tip of the cushion P can be brought into contact with the surface 10a of the door 10, so that the gap between the collar frame 2b and the door bottom of the door 10 can be closed. . Therefore, it can be set as the state which isolate | separated the room | chamber interior and the outdoors substantially airtight in the state which closed the door 10. FIG.

  On the other hand, when the room and the outdoor are in communication with each other, the operating lever 25r of the operating mechanism 25 is operated to swing the operating lever 25r downward (see FIG. 5B). Then, since the moving plate 21a moves upward, it is guided by the guide mechanism 22, and the cushion P moves so as to approach the inner surface of the bottom wall of the case 20a (that is, the inner bottom surface s of the housing groove 2g). Then, the cushion P can be accommodated in the opening of the case 20a (that is, the opening of the accommodation groove 2g). Therefore, even when the door 10 is closed, the end of the cushion P can be separated from the surface 10a of the door 10, so that a gap is formed between the collar frame 2b and the door bottom of the door 10. State. Therefore, even when the door 10 is closed, the room and the outside can be vented.

(About moving plate 21a)
The through hole h formed in the moving plate 21a is formed to a length that does not interfere with the cushion guide mechanism PA and the moving plate 21a even when the moving plate 21a moves along the inner surface of the bottom wall of the case 20a. (See FIG. 4A). That is, the length of the through hole h in the axial direction is formed to be at least longer than the moving stroke of the moving plate 21a. Therefore, when the movable plate 21a moves, the cushion guide mechanism PA does not become an obstacle.

(Operating mechanism 25)
In the above example, the case where the tip of the pin 25p is provided so as to contact the lower surface of the plate 21p has been described, but the plate 21p and the pin 25p may be fixed. However, if it is set as the above structures, when installing the operation part 21 and the action | operation mechanism 25, since it becomes unnecessary to connect both, installation of the ventilation mechanism 20 becomes easy.

  Further, the operating mechanism 25 for moving the moving plate 21a is not limited to the above-described French dropping structure, and various methods can be adopted. For example, the base end of a rod-shaped lever is fixed to the moving plate 21a, and the tip of the lever is protruded from the side wall that forms the housing groove 2g in the collar frame 2b. Then, the person can hold the tip of the lever and move the lever up and down to move the moving plate 21a.

(About the guide mechanism 22)
In the above example, the case where the movable member 23 is provided with the guide groove 23g and the guide portion 24 is provided with the guide member 24b has been described. However, a guide groove may be provided in the guide portion 24 and a guide member inserted into the guide groove may be provided in the movable side member 23.

(Cushion guide mechanism PA)
The cushion guide mechanism PA is not limited to the above-described structure as long as the support plate SP and the case 20a can be connected as described above. For example, a rail-like protrusion that extends from the bottom wall of the case 20a toward the opening may be provided on the inner surface of the side wall of the case 20a, and a notch that engages with this protrusion may be provided on the side surface of the support plate SP.

(Support plate SP)
The structure of the support plate SP is not particularly limited as long as the cushion P can be held so as not to be deformed when the cushion P is moved by the operation unit 21. For example, a simple plate member may be used as the support plate SP. However, if the substantially U-shaped support plate SP as described above is used, there is an advantage that the cushion P can be fixed to the support plate SP in the same manner as in the case where the cushion P is attached to a normal door frame door.

(About cushion P)
The cushion P to be attached to the door is not particularly limited, but usually a cushion having a hollow inside is preferable. The reason for this is to increase the flexibility of the cushion P and to improve the shock absorption and the adhesion to the door 10.

  In particular, in order to increase the airtightness of the door set 1 in a state where the door 10 is closed, it is preferable to increase the contact area between the cushion P and the door 10 to improve the adhesion with the door 10. For example, if the cushion P having a substantially flat front end surface is used, the airtightness of the door set 1 can be improved.

  On the other hand, it is desirable to use the cushion P provided on the heel frame 2b on the door bottom side, which is provided with a plate-like contact piece Ps at its tip (see FIG. 1). In the case of the cushion P having a substantially flat front end surface, when the cushion P is in contact with the surface 10a of the door 10 (that is, in an airtight state), the cushion P becomes a resistance when the door 10 is opened and closed. Therefore, when opening and closing the door 10, it is necessary to operate the operation unit 21 of the ventilation mechanism 20 to switch from the airtight state to the communication state. However, if the cushion P having the contact piece Ps as shown in FIG. 1 is provided on the heel frame 2b on the door bottom side, the cushion P of the cushion P can be obtained even when the contact piece Ps of the cushion P is in contact with the surface 10a of the door 10. Resistance can be reduced. That is, when the door 10 is opened, the door 10 can be smoothly opened without operating the operation unit 21 of the ventilation mechanism 20 (that is, even in an airtight state). The operability of the set 1 can be improved.

(Installation position of ventilation mechanism 20)
In the above example, the case where the ventilation mechanism 20 is provided in the heel frame 2b on the door bottom side has been described. However, the position where the ventilation mechanism 20 is provided is not limited to the heel frame 2b on the door bottom side. The ventilation mechanism 20 may be provided in the frames 2a, 2c, 2d other than the heel frame 2b on the door bottom side.

  In particular, since a gap is easily formed between the door frame 2a on the door side and the door 10, if the ventilation mechanism 20 is provided on the door frame 2a on the door side, the ventilation in a ventilated state or in a shielded state is possible. Airtightness can be increased.

(Other examples of the operation unit 21)
The operation unit 21 of the ventilation mechanism 20 is not limited to the configuration described above. If the cushion P can be moved between the shut-off state and the ventilation state, and the movement can be fixed so that the cushion P does not move at each position, various configurations are adopted. Can do.

  Furthermore, in the above example, the case where the operation unit 21 of the ventilation mechanism 20 has a configuration in which the cushion P is switched between the cutoff state and the ventilation state has been described. That is, the case has been described in which the cushion P takes two postures, that is, a blocking state and a communicating state. However, the operation unit 21 may be configured to hold the cushion P at any position between the blocked state and the ventilated state. In this case, an advantage that the communication amount can be adjusted by operating the ventilation mechanism 20 is obtained.

  The configuration of the operation unit 21 having such a function is not particularly limited, but the following configuration can be employed.

  For example, a screw hole is formed in the support plate SP and a screw shaft screwed into the screw hole is employed as the operation unit 21. And it arrange | positions so that the axial direction of a screw shaft may be orthogonal to the surface 10a of the door 10 in the state which closed the door 10. As shown in FIG. Then, if the screw shaft is rotated, the cushion P can be moved back and forth with respect to the surface 10a of the door 10. In addition, the cushion P can be stopped at a desired distance from the surface 10a of the door 10 by adjusting the amount of rotation of the screw shaft.

(Ventilation device)
When installing the ventilation mechanism 20 in the accommodation groove 2g provided in the door frame 2, the case 20a described above is not necessarily provided. That is, you may install the operation part 21 grade | etc., Directly in the accommodation groove | channel 2g. In this case, the operation portion 21 or the like is placed in the housing groove 2g so that the inner bottom surface s of the housing groove 2g functions as the bottom wall inner surface of the case 20a described above and the opening of the housing groove 2g functions as the opening of the case 20a described above. Should be installed. However, if the case 20a is provided, an advantage that the operation of installing the operation portion 21 in the accommodation groove 2g becomes easy.

  Moreover, if the case 20a as described above is provided, the ventilation mechanism 20 can be used as a unitary ventilation device independent of the door frame 2. That is, if the case 20a of the ventilation mechanism 20 is directly fixed to the outer surface of the door frame or the like, the ventilator can be installed even in a door frame that does not have the accommodation groove 2g. Then, even if it is an existing door set, it can be easily made into a door set with high airtightness by installing a ventilator. In this case, the inner surface of the bottom wall of the case 20a corresponds to the opposing inner surface as defined in the claims.

The unit-type ventilation device having the case 20a may be provided on the door side or attached to a wall or a panel installed on the wall when the gap formed between the door frame and the door is continuously shielded. May be.
Moreover, the unit-shaped ventilation apparatus can be used for purposes other than communicating and shielding the gap formed between the door frame and the door. For example, it can also be used as a device that communicates and shields a gap formed between movable partition walls. Of course, it can also be used when the gap between the window frame and the crosspiece is cut off. In this case, the unit-type ventilation device may be provided on either the window frame or the crosspiece, but considering the ease of use of the window, the unit-type ventilation device is preferably provided on the window frame.

  The door set of the present invention is suitable for a door set used for an entrance of a residential building such as an apartment.
