TECHNICAL FIELD OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention relates to an eave provided above an opening of a building such as a house, and can be used as a shutter box of a building shutter instead of an eave.
[0002]
[Background Art]
An eave is provided above an opening such as a window of a building, and when a shutter for a building is attached to this opening, a shutter box of the shutter for the building serves as an eave. The left and right lengths of the conventional eaves and shutter box are approximately the same as the left and right lengths of the opening, and the amount of forward projection depends on the appearance of the building and the shutter curtain winding amount, etc. It was decided based on the function of.
[0003]
[Problems to be solved by the invention]
The eaves and the shutter box of the building shutter instead of the eaves are intended not only to prevent rain from entering the room, but also to make the amount of sunlight entering the room through the opening appropriate. According to conventional eaves and shutter boxes that became long and protruding forward, the west sun could enter the room, or light from the high altitude sun in the summer could not be prevented from entering the room, It was not always possible to obtain good shade conditions.
[0004]
An object of the present invention is to provide an eave which can appropriately control the amount of sunlight entering a room through an opening.
[0005]
[Means for Solving the Problems]
The eaves according to the present invention are provided with an eaves main body provided so as to protrude forward above an opening of a building, and are attached to the eaves main body so as to be able to move forward and backward, and protrude from the eaves main body when moving forward to increase the eaves area. And a movable body.
[0006]
According to this eaves, by moving the movable body forward and projecting from the eaves main body, light from the high altitude sun in summer can be blocked from entering the room through the opening, and the movable body can be retracted in winter. By reducing the eaves area, light from the low altitude sun enters the room through the opening.
[0007]
Here, the direction of forward and backward movement of the movable body with respect to the eaves main body may be a direction parallel to the overhanging direction of the eaves main body, or may be a direction perpendicular to this overhanging direction, in other words, the left and right direction of the opening. .
[0008]
In order to assemble the movable body to the eaves main body so as to be able to move forward and backward, the movable body may be housed inside the hollow eaves body so as to be able to advance and retreat, and the movable body may be placed outside the eaves main body. May be freely reciprocated.
[0009]
In order to move the movable body back and forth with respect to the eaves main body, a structure may be adopted in which the driving force from a drive source such as a motor is transmitted to the movable body and the movable body is automatically moved, or a manual device such as a handle is used. The movable body may be manually moved.
[0010]
Further, a awning member such as a cloth or a droop which can be freely suspended from the movable body may be provided. By providing such a sunshade member, for example, it is possible to prevent sunlight at a low altitude in the morning and evening in the summer or the like from entering the opening. In addition, it is possible to prevent the laundry dried on the outside of the opening from getting wet in rainy weather by the sunshade member.
[0011]
The awning member may be vertically movable from the movable body when the movable body has reached the forward limit, and may be suspended, or when the movable body has reached both the forward limit and the backward limit. It may be able to move up and down when it is down. In the latter case, there are many possible combinations of the movable body and the awning member, and the use of the movable body and the awning member depends on the direction of the opening provided with the eaves, the weather, and the like. Building occupants can be devised.
[0012]
In order to move the awning member up and down from the movable body, an automatic device type structure using a motor or the like may be used, or a manual type structure may be used.
[0013]
When the forward and backward movement of the movable body with respect to the eaves main body and the vertical movement of the sunshade member from the movable body are of an automatic device type, and when the sunshade member is vertically moved when the movable body has reached the forward limit. Can be configured such that both the forward and backward movement of the movable body and the up and down movement of the sunshade member are performed by a drive source such as a single motor.
[0014]
In addition to the above, the lower surface of the eave may be a flat surface having the same height from the rear end to the front end, or may have a stepped shape in which the rear end is low and the front end is high. In the latter case, when the altitude is low as in winter, the sunlight from the sun is not blocked by the tip of the eave (however, when the movable body is provided on this eave, The movable body is housed in the eaves main body.).
[0015]
If the lower surface of the eaves is stepped in this way and the movable body and the sunshade member are provided on the eaves, the eaves enter the room according to the season, the direction of the opening provided with the eaves, and the like. It becomes possible to select a variety of sunshine conditions that suit the occupants' preferences.
[0016]
Generally, if the left and right lengths of the eaves are made longer than the left and right lengths of the opening, the amount of sunlight such as the sunshine entering the room can be reduced.
[0017]
In addition, the left and right lengths of the eaves that protrude forward at the top of the opening of the building are longer than the left and right lengths of the opening, and the sun elevation at each 45 degrees in the east-west direction centering on the south at the summer solstice is α degrees When the height from the lower end of the opening to the lower surface of the eaves is H, the length from each left and right end of the opening to each left and right end of the eaves is L, and the amount of eaves extending forward is A, If each of A is equal to or greater than Htan (90-α), it is possible to prevent sunlight from entering the room for a long period of time during the daytime when sunlight is strong.
[0018]
An eave having such a size is effective for an eave provided at an opening facing south or substantially south. However, for eaves that are provided at openings that face east or east, or west or generally west, the sunshine during the daylight can be reduced by extending the left and right lengths of the eaves farther to the south than the openings. It is possible to prevent light from entering the room through the opening. In addition, by installing a removable sunshade member on the eaves provided at the opening facing eastward or almost eastward, or westward or almost westward, the front of the opening is shielded by this sunshade member, so that the sunrise and sunset in the summer solstice Light from the sun can be prevented from entering the room.
[0019]
These eaves may be eaves provided with the above-mentioned eaves main body, movable body and sunshade member, or may be other eaves.
[0020]
When the eaves are provided with a movable body, the number of the movable bodies may be only one protruding forward, two protruding in each of the left and right directions, or one protruding forward. And two protruding in each of the left and right directions, a total of three, or one protruding in one of the left and right directions, and one protruding forward and one of the left and right directions And a total of two protruding pieces. If the eaves are provided with a movable body that projects in at least one of the left and right directions, an eave whose left and right length is longer than the opening can be realized by projecting and moving the movable body, When a large left and right length of the eaves is not required due to the relationship with the direction of the sun, the left and right lengths of the eaves can be made substantially the same as the opening by retracting the movable body, so that a good appearance can be achieved. . When the number of movable bodies is plural, these movable bodies may move simultaneously or may move individually.
[0021]
Which of the above movable bodies is to be provided on the eaves may be determined according to the direction of the opening where the eaves are provided, etc. Regardless of the direction of the opening, etc., one movable body protruding forward and two movable bodies protruding in left and right directions shall be provided, and the resident or user of the building may move forward or backward. By selecting the movable body to be made, a desired shade situation and a sunny situation may be obtained.
[0022]
The above-mentioned eaves may be ordinary eaves provided in a building, or may be a shutter box of a building shutter instead of an eave.
[0023]

When the forward movement of the movable body 6 reaches a certain distance, since the hole 18 is formed in the partition plate 7, the hook portion 15A is fitted into the hole 18 to be locked, and the movable body 6 is further locked. It is designed to prevent running. At this time, the movable body 6 has reached the forward limit. When a retreating force is applied to the movable body 6 in this state, since the lower surface of the hook portion 15A is curved, the stopper 15 rotates in a direction against the urging force of the spring 17 so that the hook portion 15A After escaping from 18, the movable body 6 can travel backward.
[0026]
A dog 20 for operating a limit switch 19 attached to the movable body 6 is integrally attached to the stopper 15, and when the hook 15A is fitted into the hole 18 and the stopper 15 rotates around the shaft 16, ie, When the movable body 6 reaches the forward limit, the dog 20 separates from the limit switch 19 and the switch 19 is turned off.
[0027]
As shown in FIG. 2, a motor 21 is disposed at a rear portion of the upper chamber of the eaves main body 5, and the motor 21 is, for example, a DC torque motor, and is rotatable forward and backward. As shown in FIG. 4, a pulley 23 is connected to the motor 21 via a belt 22. The pulley 23 is rotatably fitted to a shaft 24 laid on the eaves main body 5 and is connected to each other by a connecting cylinder 25. The connecting cylinder 25 and the rotating body 26 are rotated by the driving force of the motor 21. The rear ends of the wires 27 extending in the forward direction of the movable body 6 are fixed to the respective rotating bodies 26, and these wires 27 are guided by guide portions 12A formed at the ends of the rollers 12 so that the movable bodies 6 The sunshade member 28 shown in FIG. 11 is connected to the tip of the member through a horizontally long connecting member 29.
[0028]
A horizontally long bar 30 is attached to the tip of the awning member 28, and as shown in FIG. 10, the awning member 28 is turned downward from a guide roller 31 provided on the movable body 6. Therefore, when the wire 27 is wound around the rotating body 26 and the entire awning member 28 is housed inside the movable body 6, the bar 30 is attached to both sides of the movable body 6. It fits into a concave portion 32 formed to open downward. Further, when the entire movable body 6 is housed inside the eaves main body 5, the ends of the bar 30 protruding laterally from the recesses 32 are formed to open forward on both side surfaces of the eaves main body 5. It fits in the recess 33.
[0029]
As shown in FIG. 10, a lever 34 is incorporated at the inner end of the movable body 6 and is rotatable about a shaft 36 while being urged by a spring 35. When the bar 30 is fitted into the recess 32, the limit switch 37 is turned off, and when the bar 30 escapes from the recess 32, the limit switch 37 is turned on.
[0030]
On the outer periphery of the connecting cylinder 25 connecting the two left and right rotating bodies 26 shown in FIG. 4, two rotating cams 38 are rotatably provided in proximity to the respective rotating bodies 26. This rotary cam 38 is shown in FIGS. 8 and 9, and the rotary cam 38 is disposed on the connecting cylinder 25 with its axial position regulated by the two ring members 39 of FIG. 9. As shown in FIG. 8, a plurality of grooves 40 are formed in a circumferential direction on the outer peripheral surface of the connecting cylinder 25 corresponding to the arrangement position of the rotating cam 38, and a needle 41 is inserted into each groove 40. In this embodiment, as shown in FIG. 9, each groove 40 is divided into two in the axial direction by a dividing member 42, and a needle 41 is inserted into each divided groove.
[0031]
Since the depth of the groove 40 is gradually reduced in the direction A in FIG. 8, when the connecting cylinder 25 is rotated in the B direction, the groove 40 is connected via the needle 41 which moves in the A direction relative to the connecting cylinder 25. The cylinder 25 and the rotation cam 38 are connected, and the rotation cam 38 rotates integrally with the connection cylinder 25. On the other hand, when the connecting cylinder 25 rotates in the direction A, the connection between the connecting cylinder 25 and the rotating cam 38 via the needle 41 is released, and the rotating cam 38 is in a free state, and only the connecting cylinder 25 rotates. At this time, the projection 38A is formed on a part of the circumferential direction of the rotating cam 38, and the center of gravity of the rotating cam 38 is located near the projection 38A. It will rotate freely until it stops at that position.
[0032]
As described above, the one-way clutch that transmits only the rotation of the connecting cylinder 25 in the B direction to the rotating cam 38 is formed by the groove 40 and the needle 41.
[0033]
As shown in FIG. 6, near the rotating cam 38, a lever 44 whose upper end is swingably mounted around the shaft 43 is attached to the eaves body 5. A cam follower 46 abutting on 38 is provided. A hook 48 is connected to the lower end of the lever 44 via a link 47, and the engaging portion 48A at the tip of the hook 48 that rotates about a shaft 49 has a cam follower 46 at a position other than the protrusion 38A of the rotary cam 38. When the movable body 6 is in contact with the entire eaves body 5 and is housed inside the eaves main body 5, the movable body 6 is engaged with the rear end 6 </ b> B. It is possible to prevent the vehicle from traveling forward by its own weight on the partition plate 7 which is inclined.
[0034]
Next, the operation will be described. In an initial state in which the entire movable body 6 is housed inside the eaves main body 5, the engaging portion 48A of the hook 48 in FIG. 6 is engaged with the rear end 6B of the movable body 6, and the sunshade member in FIG. The bar 30 at the tip of 28 is fitted into the concave portion 32 of the movable body 6 and the concave portion 33 of the eaves main body 5. When the motor 21 shown in FIG. 4 and the like is rotated forward by a switch device (not shown), this rotation is transmitted to the connecting cylinder 25 and the rotating body 26 via the belt 22 and the like, and the connecting cylinder 25 is moved in the direction B in FIG. The rotation cam 38 also rotates via the needle 41, and as a result, the cam follower 46 in FIG. 6 is pushed by the projection 38 </ b> A of the rotation cam 38, and the lever 44 swings about the shaft 43. As a result, the hook 48 is rotated about the shaft 49 by the pressing action of the link 47, the engaging portion 48A is disengaged from the rear end 6B of the movable body 6, and the connecting portion 50 between the link 47 and the hook 48 is moved by the movable body. The movable body 6 receives the pressing force to push the receiving portion 51 provided on the partition plate 6, and even if the rollers 11, 12 and the like have frictional resistance, the movable plate 6 is inclined forward and downward. It starts to run forward on its own weight.
[0035]
At this time, since the rotating body 26 is also being rotated by the motor 21, the wire 27 shown in FIG. 2 and the like is paid out from the rotating body 26, and therefore, the moving speed of the wire 27 at the corresponding speed is adjusted. When the traveling distance reaches a predetermined value, the hook 15A of the stopper 15 shown in FIG. 7 is fitted into the hole 18, so that the movable body 6 protruding from the eaves main body 5 and traveling is stopped. When the movable body 6 projecting from the eaves main body 5 stops at the forward limit as described above, the dog 20 of the stopper 15 rotated about the shaft 16 turns off the limit switch 19. The electric drive circuit of the motor 21 is shut off, and the normal rotation of the motor 21 stops.
[0036]
Thereafter, when the motor 21 is rotated forward again by the switch device, the wire 27 is further extended by the rotation of the rotating body 26. Therefore, while the movable body 6 is stopped by the stopper 15 at the forward limit, the sunshade member 28 Due to the weight of the bar 30 provided at the tip thereof, the bar starts to hang from the movable body 6, and when the awning member 28 hangs from the movable body 6 by a predetermined length as shown in FIG. The motor 21 is stopped by a signal from a sensor (not shown) that is detecting.
[0037]
When the motor 21 is rotated in the reverse direction by the switch device, the wire 27 is wound around the rotating body 26 that rotates in the reverse direction, so that the awning member 28 rises and is housed inside the movable body 6, and the bar 30 is moved to the position shown in FIG. Since the limit switch 37 is turned off via the lever 34 when the vehicle enters the concave portion 32 of the movable body 6 shown in FIG. Thereafter, when the motor 21 is further rotated in the reverse direction by the switch device, the retracting force is generated on the movable body 6 by the pulling force of the wire 27 wound on the rotating body 26. As a result, the hook portion of the stopper 15 is 15A escapes from the hole 18 in FIG. 7 and the movable body 6 starts retreating.
[0038]
At this time, since the connecting cylinder 25 shown in FIG. 8 is rotating in the direction A, the rotating cam 38 is freely rotated to the position where the projection 38A is directed downward and stopped. Therefore, the lever 44, the link 47, and the hook 48 are in a state shown by a solid line in FIG. 6, and in this state, the movable body 6 retreats. The inclined surface 48B of the engaging portion 48A of the hook 48 runs up, and then the engaging portion 48A is again engaged with the rear end 6B by the biasing force of the spring 45.
[0039]
When a sensor (not shown) detects that the movable body 6 has retreated to a position where the engaging portion 48A of the hook 48 is engaged with the rear end 6B, the reverse rotation of the motor 21 is stopped by a signal from this sensor, At this time, since the bar 30 of the sunshade member 28 is fitted into the concave portion 33 of the eaves main body 5, the whole is returned to the initial state. Therefore, the above-described operation such as moving the movable body 6 forward can be repeated.
[0040]
As described above, according to the present embodiment, the state in which the movable body 6 is made to protrude from the eaves main body 5 without protruding from the eaves main body 5 and the state in which the movable body 6 is made to protrude from the eaves main body 5 to increase the eaves protruding amount Thus, it is possible to create a state in which the awning member 28 is stored inside the movable body 6 and a state in which the awning member 28 is hung down from the movable body 6 when the overhang amount is large.
[0041]
For this reason, when the eaves 1 are provided in the south-facing opening 3, in order to block light from the high-altitude sun in the daytime in summer from entering the room through the opening 3, the shade member 28 is required. May be protruded from the eaves main body 5. When the opening 3 is provided eastward or westward to block sunlight from a low altitude in the morning and evening into the room, the sunshade member 28 may be hung down from the movable body 6. Also, no matter what direction the opening 3 is provided, if the sunshade member 28 is hung in the rain, it is possible to prevent the laundry dried on the front of the opening 3 from getting wet. When the movable body 6 is stored in the eaves main body 5 in winter, light from the sun from a low altitude enters the room through the opening 3, and the movable body 6 protrudes from the eaves main body 5. The amount of sunlight entering the room in winter can be limited.
[0042]
For this reason, it is possible to obtain various situations of the eaves 1 depending on the direction of the opening 3 where the eaves 1 are provided, the weather, and the preference of the building occupants regarding the sunshine, and the like, and can respond to various situations.
[0043]
Further, in the present embodiment, as shown in FIG. 2, the height of the tip 5B is higher than the height of the rear end 5A of the lower surface of the eaves main body 5, and the lower surface of the eaves main body 5 is stepped. Therefore, when the movable body 6 is stored in the eaves main body 5 in winter, the movable body 6 enters the room through the opening 3 more than when the front end 5B is at the same height position 5B ′ as the rear end 5A. You can increase the amount of sunlight.
[0044]
Also, as shown in FIG. 1, since the left and right lengths of the eaves main body 5 and the movable body 6 are longer than the left and right lengths of the opening 3, the amount of west sun incident on the opening 3 is limited. it can.
[0045]
In addition to the above, in the present embodiment, the forward / backward movement of the movable body 6 and the up / down movement of the sunshade member 28 are performed by using one motor 21 as a drive source, so that simplification of the structure is realized. ing.
[0046]
12 to 16 show an eave 61 according to another embodiment of the present invention. This eave 61 is a shutter box of a building shutter similarly to the above embodiment, and guide rails 70 of a shutter curtain are provided on the left and right sides of the opening 63, but this eave 61 may be a normal eave.
[0047]
As shown in FIG. 12, when the left and right length of the opening 63 is W1, the left and right length of the eave 61 is set to W2 larger than W1 so that the left and right ends of the eave 61 are left and right. Let L be the length to each end. Further, as shown in FIG. 13, when the height dimension from the lower end of the opening 63 to the lower surface of the tip of the eave 61 is H (in the drawing, the upper end of the opening 63 and the horizontal lower surface of the eave 61 have the same height. However, the case where the lower surface of the eaves 61 is higher than the upper end of the opening 63 is included.), And the amount of the eaves 61 projecting forward is A.
[0048]
When the opening 63 is provided in the south direction and the eaves 61 are also in the south direction (see FIG. 15), when the solar altitude at each 45 degrees in the east-west direction centering on the south at the summer solstice is α degrees Then, L and A are equal to or larger than Htan (90-α) (see FIGS. 12 and 13).
[0049]
According to this, even when the eaves 61 are ordinary eaves and the right and left end portions of the opening 63 are not provided with the shutter rails 70 protruding forward from the wall, the eaves 61 can be used during the daytime when sunlight is strong. For a long time, light from the sun can be blocked from entering the room through the opening 63 by the eaves 61, and a good shade state can be obtained. The same effect can be obtained when the eaves 61 are provided in the opening facing south.
[0050]
By the way, when α is 70 degrees, Htan (90−α) is about 0.36H. In the summer solstice, the mid-south altitude of the sun is 79 degrees in Tokyo at 35 degrees north, 76 degrees in Sapporo at 43 degrees north, and 83 degrees in Kagoshima at 31 degrees north.
[0051]
FIG. 15 shows an east-facing eave 71 and a west-facing eave 81, and also shows a solar operating angle β from the sunrise to sunset in the summer solstice and a solar operating angle γ from the sunrise to sunset in the winter solstice.
[0052]
In most parts of Japan, the direction of the sunrise and sunset at the summer solstice is within 45 degrees north of the east and west. For this reason, when the left and right dimensions and the amount of overhang of the eaves 71 and 81 with respect to the opening are the same as those of the eaves 61 described above, the sunshade member 108 is hung down at the tip of the eaves 71 and 81 as shown in FIG. This prevents light from the sun at the sunrise on the summer solstice from entering the east-facing opening, and prevents light from the sunset sun on the summer solstice from entering the west-facing opening, and therefore has strong sunlight. It is possible to prevent sunlight at the time of sunrise and sunset from entering the room. It is desirable that the awning member 108 can be detachably attached to the eaves 71 and 81 so that the occupant can meet the occupant's preference regarding the sunshine.
[0053]
From the above, as described above, the eaves in which L and A are the same as or larger than Htan (90-α) are not only the south-facing or generally south-facing openings, but also other than this. , The amount of sunlight entering the room from the opening can be optimized.
[0054]
The eaves 61, 71, 81 shown in FIGS. 12 to 16 may have the same structure and operation as those of the eaves 1 shown in FIGS. That is, A in FIGS. 13 and 14 is obtained by the amount of protrusion of the movable body from the eaves main bodies of the eaves 61, 71 and 81, and the sunshade member 108 of FIG. 16 protrudes from the eaves main bodies of the eaves 71 and 81. You may make it hang down from a movable body.
[0055]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, the effect that the quantity of the sunlight which enters into a room | room through the opening part of a building can be obtained appropriately.
