TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof material elevating mechanism for vertically moving the other edge of a roof material whose one edge can be moved up and down with one edge as an axis.
[0002]
[Prior art]
There is a roofing material for moving the edge of the other side up and down with the edge of the other side moving up and down with the edge of the other side as the axis. Such a roofing material is useful because the space below the roof can be changed as needed.
The lifting and lowering of the roof material is performed by a lifting mechanism.
A general elevating mechanism includes a driving unit and a linear body that is unwound or wound by the driving unit. The distal end of the linear body is connected to the edge on the other side of the roofing material.
According to this elevating mechanism, the other edge of the film material can be moved downward by unwinding the linear material, and the other edge of the film material can be moved by winding the linear material. It can be moved upward.
[0003]
By the way, such a roof material may be subjected to a force to move it upward due to, for example, pressure from below. Therefore, when an elevating mechanism is attached to the roofing material, a lock mechanism is also provided to prevent the roofing material from moving freely upward even when an upward force is applied to the roofing material located below. It is usual to do.
[0004]
If the roof mechanism is provided with the elevating mechanism and the lock mechanism as described above, it is certainly sufficient to move the roof material up and down. However, it is the person who manages the roofing material that operates the lock mechanism each time the roofing material is moved downward to perform the locking, and operates the lock mechanism each time the roofing material is moved upward to release the roofing material. It's tedious for you.
[0005]
[Problems to be solved by the invention]
The present invention has been made to solve such a problem, and provides an elevating mechanism which has the function of the lock mechanism and can perform locking or releasing as required without performing any operation. Is the task.
[0006]
[Means for Solving the Problems]
The present applicant proposes the following elevating mechanism in order to solve such a problem.
The roofing material raising / lowering mechanism of the present invention is a roofing material raising / lowering mechanism for vertically moving the other side edge of the roofing material in which the other side edge can be moved up and down with the one side edge as an axis. is there.
The roofing material elevating mechanism has an end rotatably connected to the other side edge of the roofing material, and an other end rotatably moving up and down by a driving force of a driving unit. A rotatable member that is rotatably connected and provided with a groove having a depth direction that connects the one end and the other end, and that the groove is formed when the roofing material is at the lowest position. And a locking body locked by the groove by fitting. The groove can be provided, for example, between the one end and the other end.
This roofing material elevating mechanism raises and lowers the rotating member connected to the elevating part moved up and down by the driving means together with the elevating part, and accordingly the other end of the film material connected to the rotating member. By moving the side edge up and down, the film material is moved up and down.
Here, when the elevating unit is descending, in other words, when receiving an upward force from the elevating unit, the rotating member turns the opening of the groove downward. Accordingly, the groove of the descending rotating member covers the locking member from above, thereby creating a state where the locking member is present in the groove.
When the elevating unit is completely lowered and no longer receives a force from the elevating unit, the rotating member rotates about the one end connected to the film material as an axis, and lowers the other end connected to the elevating unit. . Accordingly, the opening of the rotating member is directed in the direction of the roofing material (for example, horizontally or diagonally upward).
In this state, even if an upward force acts on the roofing material and an upward force acts on the rotating member from the roofing material, the roof material moves upward because the groove is locked with the locking body. Never.
On the other hand, when the elevator is raised by the driving means in order to raise the roofing material, an upward force is applied to the rotating member from the elevator, as in the case where the elevator is lowered. In this case, as described above, the groove of the rotating member faces downward. As a result, when the elevating part is raised, the locking between the locking body and the groove is naturally released, and the roofing material lifted by the rotating member rises.
The above-described operation of locking the locking body and the groove or releasing the locking is automatically performed when the lifting unit is moved up and down.
Therefore, this roof material elevating mechanism not only obtains the same effect as the case where there is a lock mechanism without using a lock mechanism, but also requires an operation of locking or releasing the lock mechanism. Will not do.
[0007]
The elevating unit described above may be of any type. For example, the elevating part can be the tip of the linear body. In this case, the above-mentioned drive means can be a winch, for example, which unwinds or winds the linear body to move the tip of the linear body up and down.
[0008]
The roofing material described above may be any material. For example, a film material or a film material can be used. The film material is often used as a roof material for performing the above-described elevating movement, and when it is fanned by the wind, an upward force is likely to work, so the effect of using the elevating mechanism of the present invention is remarkable. Appears.
[0009]
The specific configuration of the rotating member is not limited as long as it is as described above. For example, the rotating member is a member having a substantially U-shaped cross section, the one end is near the distal end of one linear portion of the U-shape, and the other end is near the base end of the linear portion, The groove may be a portion sandwiched between both straight portions of the U-shape.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS.
The elevating structure of the roofing material in this embodiment is applied to a building as shown in FIG.
[0011]
This building includes a wall K, a beam H provided thereon, and a roof Y further provided thereon.
The beam H is configured by reinforcing steel bars.
The roof Y in this embodiment includes two roof materials 10. In this embodiment, the roofing material 10 located on the left side in FIG. 1 is referred to as a first roofing material, and the roofing material 10 located on the right side is referred to as a second roofing material. As shown in FIG. 2, both roofing materials 10 include a membrane material 11 and a plurality of aggregates 12.
Although not limited to this, the film material 11 is formed in a rectangular shape, and its material is made of resin. Although not limited to this, the film material 11 has translucency. Therefore, the sunlight is also guided below the roof Y through the film material 11.
The aggregate 12 is a metal rod-like body bent in an arc shape. Then, both ends are fixed at positions corresponding to one side of the film material 11 and the side opposite thereto. The aggregate 12 is subjected to a force that attempts to return to a linear shape. Therefore, the film material 11 is tensioned to be pulled between the two sides, and its smoothness is maintained, so that the roof material 10 is excellent in appearance.
[0012]
The first roofing material 10 of the two roofing materials 10 in this embodiment has one side fixed to the beam H. The side opposite to the fixed side is supported by the column S, and is positioned higher than the fixed side. In other words, the film material 11 in the first roofing material 10 is formed to have a slope that climbs from the fixed side to the opposite side.
One side of the second roofing material 10 is connected to the side of the first roofing material 10 indicated by the support S. This connection allows rotation of the second roofing material 10 about the connected side of the second roofing material 10 connected to the first roofing material 10. For example, hinge connection This connection is made at.
[0013]
The second roofing material 10 rotates around the side on the column S as an axis, and faces one side (edge) on the column S as shown by a solid line and a broken line in FIG. The other side (edge) is moved up and down.
In order to make this possible, the tip of the linear body 40 is attached to the side on the other end side of the second roofing material 10 via the connecting mechanism 30. The linear body 40 is, for example, a wire. The linear body 40 reaches the winch 60 via the two pulleys 50. The winch 60 corresponds to the driving means of the present invention, and is capable of unwinding or winding the linear body 40 described above.
When the winch 60 winds up the linear body 40, the distal end of the linear body 40 rises, and accordingly, the connecting mechanism 30 connected to the distal end of the linear body 40, and the second roofing material 10 connected thereto. Of the other end rises. On the other hand, when the winch 60 unwinds the linear body 40, the distal end of the linear body 40 descends, and accordingly, the connecting mechanism 30 connected to the distal end of the linear body 40, and the second roof connected thereto. The side on the other end side of the material 10 descends. With the above-described mechanism, the side on the other end side of the second roofing material 10 moves up and down.
[0014]
FIGS. 3 and 4 are enlarged views of the connection mechanism 30 and its surroundings when the second roofing material 10 is located near the lower end.
The coupling mechanism 30 includes a connection member 31 and an offset hook member 32.
[0015]
The connection member 31 includes a support fitting 311 and a holding fitting 312. The support fitting 311 has a rectangular parallelepiped shape, and includes two main bodies 311A both arranged along the lower surface of the film material 11 and a shaft 311B arranged through both ends thereof. . The presser fitting 312 is formed in a plate shape.
Although not shown, two holes are provided at corresponding positions of the support fitting 311 and the holding fixture 312, and two bolts are provided through the holes and the bolt 313 that has passed through the film material 11. By screwing the nut 314, the connection member 31 is fixed to the edge on the other end side of the film material 11 described above.
[0016]
The offset hook member 32 corresponds to the rotating member of the present invention, and in this embodiment, is a member having a substantially U-shaped cross section. The offset hook member 32 has two straight portions. A hole penetrating in the thickness direction is provided in the vicinity of one end of the straight portion, and the shaft 311B described above is inserted therein. Thus, the offset hook member 32 can rotate around the shaft 311B.
On the other hand, a U-shaped bracket 322 that straddles the offset hook member 32 in the thickness direction is attached via a shaft 323 near the base end of the linear portion. The offset hook member 32 is rotatable about a U-shaped bracket 322 about a shaft 323. Note that the tip of the linear body 40 is connected to the upper side of the U-shaped bracket 322.
A groove 321 is provided between the two straight portions. The depth of the groove 321 is defined as a direction connecting the shaft 311B and the shaft 323.
[0017]
On the beam H, a cushioning material 70 and a locking rod 80 are provided.
The cushioning material 70 is for positioning the lowermost position of the roofing material 10 and preventing the lowered roofing material 10 from interfering with the beam H. The material is not specified, but the cushioning material 70 in this embodiment is made of an elastic material such as rubber.
The locking rod 80 is a rod-shaped body configured to be thick enough to lock with the groove 321 and corresponds to the locking body of the present invention. The locking rod 80 is supported at both ends by columns 81. The locking bar 80 is provided at a position where it fits into the groove 321 and locks with the groove 321 when the roofing material 10 is at the lowest position.
[0018]
As described above, the roofing material 10 can be raised by winding the linear body 40 with the winch 60, and can be lowered by unwinding the linear body 40.
The operation of the coupling mechanism 30 and the relationship with the locking rod 80 at that time will be described with reference to FIG.
[0019]
When the linear body 40 is unwound with the winch 60, the tip end of the linear body 40 descends, and the offset hook member 32 connected to the U-shaped bracket 322 and the shaft 323 also descends. At this time, an upward force from the linear body 40 acts on the shaft 323 of the offset hook member 32 via the U-shaped bracket 322. As a result, the offset hook member 32 takes a posture such that the opening of the groove 321 faces downward (FIG. 5A).
When the roofing material 10 further descends, it hits the cushioning material 70. This is the lowest position of the roofing material 10. If the unwinding of the linear member 40 by the winch 60 is not stopped immediately even when the roofing material 10 reaches the lowermost position, the linear member 40 becomes slack, and the linear member 40 is loosened from the linear member 40 through the U-shaped bracket 322. The upward force acting on the offset hook member 32 from the linear body 40 disappears. As a result, the offset hook member 32 rotates around the shaft 311B by its own weight, and assumes a posture as shown in FIG. 5B. At this time, the opening of the groove 321 faces the roofing material 10 side, and the locking bar 80 fits into the inside.
[0020]
At this time, it is assumed that an unintended upward force acts on the roof material 10 such as an upward force acting on the film material 11 due to, for example, wind from below. At this time, an upward force acts via the connecting member 31 near the front end of the linear portion of the offset hook member 32. Thus, the offset hook member 32 rotates counterclockwise about the shaft 311B in FIG. 5, and assumes a posture as shown in FIG. 5C. At this time, since the groove 321 and the locking bar 80 lock with each other, the roofing material 10 is locked, and the roofing material 10 is prevented from unintentionally ascending.
[0021]
When the linear body 40 is wound up by the winch 60 from the state of FIG. 5B, tension acts on the linear body 40, whereby the U-shaped bracket 322 is attached to the shaft 323 of the offset hook member 32. Through this, an upward force from the linear body 40 acts. As a result, the offset hook member 32 assumes a posture as shown in FIG. When the linear body 40 is wound up by the winch 60 as it is, the roofing material 10 rises as it is.
[0022]
