Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an opening/closing type door sash.

[Conventional technology]

In recent buildings, indoor ventilation has become an important issue due to improvements in indoor airtightness due to the spread of aluminum sash and the increasing quality of various building materials and fittings, as well as technological advances in various air conditioning equipment.

In particular, it has been academically and statistically proven that the increase in lung cancer caused by smoking, which has been viewed as a problem in recent years, has a great impact not only on the smokers themselves, but also on those who inhale indoor air due to smoking. It has been proven.

However, conventional shutter shutters had a complicated mechanism for the rack that opened and closed the slats. That is, the slats were opened and closed by swinging the rack not only up and down, but also back and forth. In addition, the left and right drive frames were only fixed to the fuselage on each side, and there was no connection between the left and right drive frames.

Moreover, the manual type and the electric type have completely different conditions.

[Problem that the invention seeks to solve]

Due to the above-mentioned configuration, the conventional Satsushi Morito has the following problems.

(1) Since the rack swings vertically and longitudinally,
The movement was not clear, and this resulted in unequal opening and closing degrees of each slat, resulting in poor ventilation and rain protection.

(2) Since the left and right drive frames were not tightly connected, if the intermediate band on both sides was cut, the function of the shutter shutter would disappear and it would be easy for intrusion to occur from the outside, making it impossible to achieve the purpose of crime prevention. .

(3) There was no commonality between manual and electric types, which led to high costs and required a large expense burden when changing models.

[Means for solving problems]

In this invention, a rack is loosely fitted into the left and right drive frames via the rack center frame, and the left and right drive frames are tightly connected to each other with a surface lattice pipe made by inserting hard piano wire. At the same time, rack horizontal elongated holes of the same number as the number of slats are formed at intervals in the above rack, and the slat protrusions attached to the arms of the slat holder are slidably accommodated in the rack horizontal elongated holes of the bracket. By fitting it, it was composed of Satsushi Yoroto.

[Function] When the above-mentioned shutter sash is installed at the window of a building, the left and right racks move up and down while being loosely fitted in the holder frame, making it possible to move each slat clearly. The degree of opening and closing is balanced, providing good ventilation and rain protection, allowing for sufficient natural ventilation when needed. In addition, since the left and right drive frames are tightly connected with a grid pipe made by inserting hard piano wire, it is impossible to cut the intermediate band, and external intrusion is easily prevented, increasing the crime prevention effect. It is possible to change the formula to improve functionality at low cost.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

First, the structure will be explained. The door satsushi A according to the present invention is structured as follows. That is, as shown in FIGS. 1 to 5, the drive frame 1 serving as the base has an inner wall surface having a plate width from the rear position to the front end in plan view, and a plate width from the rear end to the front midway position. Extrusion molding of light metal, etc. is carried out in such a manner that the intermediate zone of the inner wall surface and the front end of the outer wall surface are connected by side front plates arranged at right angles. It is organized into a unified body. Two drive frames of the same shape as described above 1.
1 are erected symmetrically on both sides of the shutter sash A at specified intervals. In this embodiment, a band-shaped holder frame 2 formed by extrusion molding similar to that described above is mounted on the front half of each inner wall surface of the drive frame 1, and stands up integrally by inserting the mounting rivets 28 in the upper and lower surfaces and crimping them. It is set up. In addition, mohair 33 having a slightly wide width is adhered to the vertical surface near the front end of the holder frame 2 to improve watertightness.

Next, at the upper and lower positions of the rear half of each inner wall surface of the drive frame 1, a rack center frame 18 having a short width and having slide fitting notches on both side edges is inserted into the rack center frame 18 with a plurality of mounting screws 19. It is fixed by a vertical arrangement. In addition, in the rack center frame with this vertical arrangement, rack horizontal elongated holes 52, into which protrusions 57 attached to the arms 54 of the slat holders 26 (to be described later) can be loosely inserted, are formed on the strip-like vertical surface according to the number of holders 26. The same number of racks 3 are formed at intervals and are arranged so as to be vertically slidable by being engaged with the bent portions at both ends.

On the back side of the rack 3 at approximately the middle height, there is a lifting bracket 15 with an L-shaped cross section, and mounting screws 1 on both sides.
It is assembled integrally with 6 screws. In this case, a square hole 61 is provided through the wide area surface of the lifting bracket 15, into which a convex portion 60 of a sprocket nut 9, which will be described later, can be inserted. The elevating bracket 15 is inserted into a vertical hole (not shown) formed in the inner wall surface of the drive frame 1 over the range in which the bracket 15 moves up and down integrally with the rack 3. Then, on the surface of the drive frame 1 in which this not-illustrated vertical connecting hole is formed, a packing 23 having a narrow vertical connecting hole corresponding to the above-mentioned connecting vertical hole is attached concentrically in the center band of the narrow side. has been done. Therefore, the elevating bracket 15 is configured to move up and down in a sliding manner within the vertical hole of the gasket 23. In this embodiment, a mounting plate is provided upright on the center surface of the flat plate at each top position of the left and right drive frame 1° holder frame 2, and a sash mounting nail hole 53 is provided on this surface.
An upper frame 5 is attached thereto, and the drive frame 1 is integrated by screwing a mounting screw (not shown) into a vertical screw hole or the like in the outer wall surface of the drive frame 1 described above. In addition, at the bottom of the drive frame 1 and holder frame 2 corresponding to the upper frame 5, a mounting plate is vertically provided below the center surface of the flat plate, and the same sash mounting nail holes 53 as described above are formed at intervals on this surface. The lower frame 4 provided in the lower frame 4 is attached and integrated by screwing unillustrated mounting screws into the same positions as above.

Between the racks 3 on the left and right sides according to the above, there is a slat E as shown below.
However, they are arranged so that they can be opened and closed in a coordinated manner in a multi-tiered manner using the assembly method described later. This slat E is formed as follows. That is, a pair of left and right slat holders 26 are formed as the base of the slat E, and one of the slat holders 26 is shown in FIG.
6, the left and right bodies are formed symmetrically. The slat holder 26 is a frame body made of a metal plate into which both ends of a glass slat 32 (to be described later) can be fitted, and is formed in a T-shape when viewed from the side. Also this slat holder 2
6 is formed with a height dimension slightly longer than the vertical interval of the rack horizontal elongated holes 52 formed in the rack 3, and a depth dimension that allows the glass slat 32 to fit therein. A slat arm portion 54 formed of a plate-shaped piece having a hypotenuse angle toward the rear from the middle portion of both sides of the slat holder 26
is installed protrudingly. A rivet hole 55 is formed in the proximal end surface of this arm portion 54, and a hole portion 56 of approximately the same diameter is formed in the distal end surface. A cylindrical slat convex portion 57 is integrally inserted into the tip hole portion 56 . Furthermore, a glass slat 32 is integrally fitted into the slat holder 26 of the above embodiment, with a volume that allows it to fit tightly into this inner area and a length that allows it to fit between the left and right racks 3. In this case, at key points in the slat holder 26 before the glass slat 32 is accommodated, there is a holder spring 51 with one end of a band-shaped elastic plate bent in a U-shape and the other end bent in a dogleg shape. It is housed in such a manner that it engages with the notch 62. This eliminates rattling within the slat holder 26 when the glass slat 32 is opened and closed by vertically moving the rack 3. The slat E as described above is assembled into the slat E by crimping the holder rivet 34 with the washer 27 inserted from the rivet hole 55 of the arm portion 54 to the hole of the holder frame 2 described above.
It is fitted so that it can rotate around 4. The convex portion 57 inserted into the tip of the arm portion 54 of each slat E according to this embodiment is loosely inserted into the rack horizontal elongated hole 52 formed in the rack 3 at each position, and when the rack 3 is operated up and down. Each slab (E) is configured to slide within this horizontal elongated hole 52, thereby enabling prescribed opening/closing operations. In this case, the slabs (E) for each stage have an interval planar configuration as a whole when they are open, and when they are closed, the lower end of the upper slat E becomes the lower slab (as shown by the solid line in Figure 1). By contacting the upper end side of H in an overlapping manner, it becomes a tile-like arrangement in which the ends are overlapped one after another, and the packing 30. It is structured as a finale.

In this embodiment, between the left and right drive frames 1, a large number of surface lattice pipes 24 shown below are horizontally installed at intervals between the rear positions of the inner wall surface for each height arrangement of the slats E described above. That is, as shown in FIG. 5, a hollow vibrator is formed inside one side of the hollow rectangular frame by extrusion molding similar to that described above between the vertical surfaces of the left and right drive frames 1 at each position, and then hardened inside. The surface lattice pipe 24, in which the center rod 39 made of piano wire is integrally buried, is fixed in a horizontal structure at the above-mentioned intervals by cleaning and tightening the mounting screws 25 from the drive frame 1 side into the screw holes at both ends thereof. ing. When the slat E is rotated to the maximum horizontal position, its upper end will come into contact with the grid pipe 24 at each position as shown in Fig. When it rotates, its lower end comes into contact with the slat E directly below it, so opening and closing operations beyond the limit are physically impossible.

Next, a plate 20 is tightly fitted between the inner and outer wall surfaces of the rear inner side of the drive frame 1, and a plate 20 is tightly fitted between the inner and outer wall surfaces of the drive frame cover 6, which will be described later.
They are fixed at intervals by inserting and tightening the fins. A drive frame cover 6 shown below is detachably attached to the front side of the plate 20 of this receiver. First, the drive frame cover 6 is formed into a band-shaped plate having a width that matches the drive frame 1 at the position where the plate 20 is installed. A hole 62 is provided therethrough. A chain guide 29 is fitted into the outer edge of the hole 62 to externally support a ball chain 10 used for spiraling the sprocket screw 7 attached to the back side. Further, an L-shaped sprocket mounting bracket 11 is fixed to the back surface of the drive frame cover 6 directly above the chain guide 29 by screwing and tightening a mounting screw 13 from the outside. Same as above chain guide 29
A sprocket mounting bracket 12 having the same shape as that described above is similarly fixed to the rear surface of the drive frame cover 6 behind the drive frame cover 6. And this upper and lower sprocket mounting bracket 11.12
At each hole position, a sprocket nut 9 is screwed into the threaded part, and the sprocket screw 7, which is wound around the threaded surface ball chain 10 in a non-circular state, has a bushing 14 fitted into its upper and lower ends, and this bushing 14. It is rotatably fitted by being inserted through the hole. The ball chain 0 is exposed through a chain guide 29 fitted into a chain guide hole 62 of the drive frame cover 6 so that it can be operated externally. When the drive frame cover 6 with the sprocket screw 7 fitted on the back side is in contact with the front side of the plate 20, the convex portion 60 of the sprocket nut 9 screwed onto the sprocket screw 7 is Lifting bracket 15
After inserting the sprocket nut 9 into the square hole 61 and assembling the elevating bracket 15 so that they can be moved up and down together, the sprocket nut 9 is inserted into the square hole 61 of the The receiver is detachably attached to the plate 20 by screwing a mounting screw 22 into a screw hole of the plate 20. As shown on the left side of FIG. 5, a cover X of the same shape without the sprocket screws 7 mounted on the back side can be attached and detached in the same way as a mere blank cover for the drive frame 1 on this side using the mounting screws 22. It is worn. Therefore, no chain guide hole 62 or the like is provided in this surface portion. (See Fig. 4) Furthermore, a screen door frame 31 is attached to the back surface between the left and right covers 6 as described above, and is detachably covered by inserting the upper and lower ends into the engaging portions of the upper frame 5 and the lower frame 4. The car window shutters are assembled into a car window shutter A as a whole.

In the above configuration, when opening the door of Suraso l-E,
When the continuous ball chain 10 exposed to the outside from the chain guide 29 is pulled in a circular manner in the spiral direction, the sprocket screw 7 coaxial with the sprocket wheel 8 on which the ball chain 10 is wound will be pulled. Since the sprocket nut 9 is rotated in the spiral direction, the sprocket nut 9 screwed into this threaded portion moves down on the threaded shaft in conjunction with the sprocket nut 9.

At this time, the elevating bracket 15 is also simultaneously lowered by the same amount through the square hole 61 into which the convex portion 60 of the bottom 9 is inserted. Therefore, the rack 3 integrated with the elevating bracket 15 descends from the uppermost position when the door is closed, using the rack center frame 18 as a guide. As the rack 3 descends, the convex portion 57 is loosely inserted into each rack horizontal elongated hole 52.
Since the slats E are also lowered in conjunction with each other, each slat E rotates in the door opening direction using the holder rivet 34 of each stage as a fulcrum, and as a result, each slat I-E can be moved arbitrarily from the closed state to the horizontal state. The door can be opened at any angle.

In addition, when each slat E opened as described above is closed in a series of shutters, when the ball chain 10 is pulled in a circular manner in the opposite direction to the above, the sprocket screw 7 turns in the screwing direction, and this The sprocket nut 9, which is screwed onto the screw shaft, will now rise. Therefore, the elevating bracket 15 rises, and the rack 3 that is integrated with it rises as well, so the slats E turn from the open state to the position where their ends abut, and the slats E are completely closed from the rain. The door can be closed by

As shown in FIG. 1, the shutter A with the above configuration is
When fitting and assembling the window part B of a building, etc., instead of assembling it in advance at a factory etc., the parts of the shutter sash A that have been made into a set are carried to the site and are assembled using the same method as described above (for example, By assembling each main part (according to the instructions included with the product), you can smoothly and easily assemble the car window shutter sash A as a whole, which is extremely convenient.
On the upper side, nails, screws, etc. 59 are inserted from each sash attachment nail hole 53 of the upper frame 5 to the picture frame C which is the upper part of this window part B.
The mounting screw 58 can be mounted quickly and reliably by driving the mounting screw 58 and the like from the large rear portion of the upper frame 5 directly above the upper frame 5. The lower side can also be attached to the window sill using the same method as above.

In addition, by using the main parts of the shutter satsushi A upside down, as shown in Figure 5, the left and right parts can be assembled symmetrically using the same parts, reducing the number of parts. be able to. Furthermore, due to the above-mentioned symmetrical configuration, the sprocket screw 7 can be placed on any side according to the site situation.
A drive mechanism for opening and closing doors can be installed. Furthermore, when the drive mechanism is to be relocated due to a change in the situation after installation, there is an advantage that the drive mechanism can be easily relocated by simply moving the related parts to the opposite side.

Furthermore, when the shutter sashes A from the car windows described above are joined adjacently to form a shutter sash for a continuous window, the following parts can be used at the mutually adjacent ends to easily form the shutter sash for a continuous window. is obtained. That is, as shown in FIG. 6, at both adjacent ends, instead of the drive frame 1 described above, a drive frame 38 is used which can simultaneously give vertical movement to both racks 3. This drive frame 38 is constructed as follows. Basically, it is almost the same as the drive frame 1 for a car window described above, but this drive frame 38 for a continuous window is formed into an H-shape in plan view, and the inner wall surfaces of the front half on both sides are The above-mentioned holder frame 2 and rack 3 are attached in the same manner, and on the back surfaces of both racks 3, there are shorter elevating brackets 15 than the elevating brackets 15 shown in FIG. It is constructed so that two identical-shaped lifting brackets 37 for continuous windows with square holes (not shown) are attached symmetrically. In order to move both brackets 37 up and down at the same time, a sprocket screw 7 having the same shape as above is used.
By screwing together a continuous window sprocket nut 36 having convex portions protruding parallel to each other on both sides of the front end of a square plate, both racks 3 are given vertical movement at the same time, and thereby the adjacent slats E are The door can be opened and closed at the same time. In addition, the surface lattice pipe 24 installed between the both side frames 1 and 38 in this continuous window type uses a continuous window surface lattice stepped screw 35 on the drive frame 38 side. Since this stepped screw 35 is attached to the drive frame 38 in advance, the stepped screw 35 can be spiraled by contacting the grid pipe 24 containing the center rod 39 at each position. Similar grid pipes 24 can be horizontally installed at intervals.

It should be noted that both the above-mentioned car window type shutter sash A and the double window type shutter sash ζ are configured so that the opening and closing operations of the slats E are performed by manual operation of the ball chain 10.
When changing from this manual system to an electric system, the electric system can be easily changed to the electric system by connecting the electric drive unit F to the position of the lifting bracket 15 shown in FIGS. 2 and 5. This electric drive unit F is configured as follows. That is, as shown in FIG. 7, the above-mentioned electric drive unit F is vertically framed in a drive frame cover 6 having the same shape as the one described above, and a vertical drive motor 40 is installed at the uppermost position within the frame. , is mounted and fixed on the motor mounting bracket 42.

A gear head 4 for deceleration is located directly below the motor 40.
1 is connected, and the top of the aforementioned sprocket screw 7 is directly connected to the output shaft of this gear head 41 via a joint 44. The lower end of this sprocket screw 7 is rotatably fitted into a plate 46 via the previously used sprocket bush 14. The previously used sprocket nut 9 is screwed into this sprocket screw 7 in the same manner. In this case, as shown in a perspective view in FIG. 2, the sprocket nut 9 is housed in the electric lifting bracket 17, which is formed by joining two symmetrical U-shaped plates, so that its convex portion 60 is inserted into the square hole 61 of the lifting bracket 15 described above.

The electric lift bracket 17 is configured to be fixed by screwing the mounting screws 16 into respective screw holes that are screwed into the wide area portion of the lift bracket 15 in advance. In addition, the motor mounting bracket 42 and the receiver mentioned above are plate 4.
A vertically arranged limit switch mounting plate 43 is attached between 6 and 6, and is activated by contact with this surface when the electric lifting bracket 17 moves up and down, thereby causing the motor 40 to rotate in the normal direction. A limit switch 45.45 is installed to stop the reverse drive. Furthermore, a sensor socket 49 and a socket 50 for receiving the motor 40 are housed in a lower position within the frame. Note that a power socket 47 for supplying power to the socket 50 is provided outside the above frame, and a switch 48 for operating the drive and stop of the motor 40 is rotatably provided adjacent to the power socket 47. As a whole, it is configured as one set of electric drive section F.

When the above-mentioned electric drive section F is replaced with the drive section position of the manual shutter sash, the drive motor 40 is driven to rotate in the normal direction by operating the switch 48, and the gear head 41. joint 4
4, the sprocket screw 7 rotates in the advancing direction, so the sprocket nut 9 screwed onto this screw shaft
By the downward movement of the slat E, the slat E can be opened in the same way as described above. Moreover, when the above motor 40 is driven in reverse,
The door can be closed with the slat E closed to the rain by performing the operation opposite to the above. Note that, like the manual drive unit described above, the electric drive unit F described above is not limited to the right side in FIG. Even when worn, the same effects as described above can be obtained.

Furthermore, when the electric drive unit F is attached to the door satsushi as described above, the built-in drive motor 40 and power socket 50 are used to simultaneously connect other devices (e.g. ventilation fans and other electrical appliances). It has the advantage of being usable. In that case, it is possible to use a plurality of sockets 50 described above.

〔Effect of the invention〕

As explained above, the present invention is configured so that the shutter body including the drive frame, holder frame, rack center frame, rack and drive frame cover, as well as the surface lattice and screen door can be assembled on-site. Since it is extremely easy to transport and easy to assemble, costs can be significantly reduced. Furthermore, each slat can be opened and closed simply by moving the rack up and down, making the operation more precise and improving the ventilation and rain protection of the shutters. Furthermore, the left and right drive frames are
Since the lattice pipe installed between the two sides is made of built-in hardened piano wire, cutting of the intermediate zone between the two sides and intrusion from the outside caused by this are prevented, resulting in crime prevention. be able to. Furthermore, by changing the drive frame for the drive unit, it is possible to easily convert from a manual type to an electric type, which has the effect of greatly increasing the functionality of the shutter shutter.
