Description

The present invention relates to a sliding body that moves along a guide rail and a hanging curtain device using the sliding body.

Cloth banners and hanging curtains are commonly used to place advertisements on the exterior walls of buildings. Of these, the hanging curtain is a highly useful advertising medium because it can secure a sufficient space for writing in a building having a sufficient height and it is easy to install a plurality of hanging curtains side by side.

As for the hanging curtain, the event to be notified is described on the main body of the strip-shaped curtain that is hung vertically. An elevating device is attached to expand and retract the curtain body. The lifting device is attached above or below the hanging curtain and is connected by a rope to an end guide bar attached to the upper or lower end of the curtain body. When the rope is connected to the guide bar at the upper end of the curtain body, the curtain body is folded or wound at the lower end when retracted, and pulled upward from there when unfolded. When the rope is connected to the guide bar at the lower end of the curtain body, the curtain body is pulled up to a storage part installed on the roof or the like at the time of storage, and is pulled down from there at the time of deployment.

10 (a) and 10 (b) show an example of a form in which the hoisting machine 53, which is an elevating device, is installed below. The ropes 52a and 52b hooked on the pulleys 54a, 54b and 54c attached to the upper end can be wound up. The other ends of the ropes 52a and 52b are connected to the fixtures 57a and 57b attached to the guide bar 56 on the upper end side of the hanging curtain main body 51. When the rope 52 is wound in the direction of the arrow that rotates in the middle of FIG. 10A, the upper end side guide bar 56 is pulled up via the pulleys 54a, 54b, 54c.

Both bar end portions 58a and 58b of the upper end side guide bar 56 project from the left and right ends of the suspension curtain body 51, and are attached so as to surround a portion for fixing the entire suspension curtain device 50. It is inserted in (60a, 60b). An enlarged view of the portion is shown in FIG. Both the guide rails 60a and 60b extend in the vertical direction, the hanging curtain main body 51 side is opened, and the retaining portions 62 and 62 having a narrow width are provided in front of and behind the opening groove 61. The guide rails 60a and 60b themselves are fixed to the wall surface W via an L-shaped plate 64 or the like fastened with bolts 65. FIG. 12 shows an example of how to fix the wall surface W, the guide rail 60, and the bar end portion 58a of the upper end side guide bar 56. In this example, the auxiliary plate 66 welded to the guide rail 60 and extended toward the wall and the L-shaped plate 64 fixed to the wall surface are fixed by bolts 67 to fix the guide rail 60 to the wall surface. ..

When the hanging curtain main body 51 is stored and deployed, both bar ends 58a and 58b of the upper end side guide bar 56 move along the guide rails 60a and 60b to move the hanging curtain main body 51 up and down without deviation. be able to. At that time, in order to slide along the guide rails 60a and 60b, both bar end portions 58a and 58b are provided with one roller 59a and 59b having the tip end as a slide bearing on the axis of the bar, respectively. .. The diameters of the rollers 59a and 59b are larger than those of both bar ends 58a and 58b of the upper end side guide bar 56, and they also act as a retainer for being caught on the retainer portions 62 and 62. The broken line in the enlarged view shown in FIG. 11 shows a situation in which the action acts as a retaining mechanism.

Further, not only the upper and lower ends of the curtain body, but also a plurality of intermediate points are often provided with middle guide bars 56c to which rollers are attached to both left and right ends as in the case of the end guide bars. Similar to the upper end side guide bar 56, rollers 59 that can rotate coaxially with the bar are attached to the left and right ends of each of the middle guide bars 56c, and the guide rails 60 are prevented from falling off while being moved up and down. To do. In addition, by restricting the movement by the guide rail even at the midpoint, it is possible to prevent the force from fluttering and fluttering or tearing.

Attaching rollers to both ends of the guide bar of such a hanging curtain is described in, for example, Patent Document 1.

Japanese Unexamined Patent Publication No. 2003-5682

However, the roller provided coaxially with the guide bar described above is effective in that it is moved so as not to come off from the guide rail, but when the roller is caught by the guide rail as shown by the broken line in FIG. 11, the roller is moved. It was fixed there, and the lifting work sometimes stopped there.

This problem is not limited to hanging curtains, but can occur with rollers incorporated into guide rails with a similar structure. Especially for guide rails that are installed in places where it is difficult to change the direction manually, once they are caught, they are forced to have a great deal of trouble when returning them. This problem could not be ignored for hanging curtains, which are often installed on the walls of buildings over 10 meters in height.

Therefore, an object of the present invention is to prevent the guide bar from coming off the guide rail and to prevent the guide bar from being caught on the guide rail so that the guide bar can move smoothly on the guide rail. As a result, the purpose is to prevent being caught when raising and lowering the hanging curtain.

The present invention solves the above problem by using a slide body for a guide rail in which two pairs of rollers whose extension lines of the rotating shaft intersect at an angle of 60 to 120 degrees are connected in the sliding direction.

Specific structures for arranging the rollers on the slide body for the guide rail according to the present invention include the following configurations. First, a rotating shaft for rotatably attaching the roller to each of the rectangular regions of a fixed plate having two rectangular regions having the same shape connected by forming a central angle of 60 degrees or more and 120 degrees or less, respectively. The rollers that are paired with each other are attached so as to face each other. The outer circumference of each of the rollers protrudes from the edge of the fixing plate. A connection portion with an object to be slid by a guide rail is provided at a position on the bisector of the angle and at the same position on the rectangular area where the distances to the four points where the rotation shafts are attached are equal. is there.

The connection part of the slide body for the guide rail is connected to the guide bar that stretches the hanging curtain to guide the guide rail.
That is, as a hanging curtain device according to the present invention,
A pair of guide rails extending in the height direction, with opening grooves with retaining holes facing each other on the outer wall surface of the building.
A plurality of guide bars inserted into the opening groove of the guide rail and raised and lowered by a rope connected to the lifting device,
In a hanging curtain device having a curtain body attached to the guide bar and stored or deployed by the lifting device.
By attaching the slide body for the guide rail to the end of the guide bar to be inserted into the opening groove, the guide bar is less likely to be caught by the guide rail, and the hanging curtain device is easy to slide.

When the slide body for the guide rail according to the present invention is inserted into the guide rail having the retaining portion along the opening groove, any of the four rollers can be used even if the position of the guide bar or the like connected to the connection portion is slightly tilted. It is suitable for contacting the inside of the guide rail and is easy to rotate, so that it can be slid smoothly. The hanging curtain device that introduces this makes it difficult for the guide bar to get caught during storage and deployment, and can greatly reduce the need for difficult repair work on the outer wall of the building.

Hereinafter, the present invention will be described in detail with reference to embodiments. First, an embodiment of the slide body for the guide rail will be described with reference to FIGS. 1 to 4.

FIG. 1 is a perspective view of a slide body 10 and a guide bar 46 (described later) attached to a connecting portion 17 of the slide body 10. The slide body 10 has four rollers 11 (11a to 11d) so that it can be stored in the slide body storage portion 33 (described later) of the guide rail 30 and slide smoothly. A rotating shaft 14 for attaching the roller 11 to the fixing plate 12 in a rotatable state penetrates the center of each roller 11.

FIG. 2 is a plan view of the slide body 10 of FIG. 1 as viewed from above. In the pair of rollers 11a and 11b that are paired on the left and right of each rotation axis 14, and the pair of rollers 11c and 11d, when the extension lines of the respective rotation axes intersect at an angle of 60 degrees or more and 120 degrees or less. It is preferable (angle θ in FIG. 2). If it deviates from this range, it may be difficult for the roller 11 to hit the slide body storage portion 33 of the guide rail 30 at a suitable angle when the slide body 10 is tilted.

FIG. 3 is a front view of the slide body 10 of FIG. 1 as viewed from the diagonally left side. The rotation shaft 14 is attached to a fixing plate 12 having rectangular regions 13 and 13 having the same shape on two surfaces, which are connected so that the angle θ of the central angle is 60 degrees or more and 120 degrees or less. The fixed plate 12 which is one metal plate may be bent at an angle θ to form a central angle, or the two metal plates have a central angle angle θ so as to be rectangular regions 13 and 13, respectively. The fixed plate 12 may be formed by welding in an arrangement. This angle can be practically used even if it is not in the above range, but it is preferable that the roller 11 is preferably in contact with the wall surface inside the guide rail 30.

The rotation shafts 14 are arranged in the rectangular regions 13 and 13 in which paired rollers (11a and 11b, 11c and 11d) are diagonally opposed to each other. It is desirable that the rollers do not come into contact with each other. As shown in FIG. 3, the outer circumference of each roller 11 protrudes from the edge 15 on the opposite side of the central angle of the fixing plate 12 (to the right in FIG. 3). As a result, the roller 11 can exert a suitable sliding effect on the retaining portion 32 (described later) in the guide rail 30.

Each of the rotating shafts 14 (14a to 14d) is also fixed to the outer shell fixing plate 21 provided on the outer angle side of the central angle. The outer shell fixing plate 21 has both bottom fixing portions 22 and 22 welded like a bottom surface covering both ends of the fixing plate 12 in the ridge direction, and outer fixing portions 23 and 23 for fixing the outer end portions of the rotating shaft 14. It is a wide roof-shaped board of the ridge, which is composed of a ridge portion 26 connecting the two. A roller 11 is attached between the rectangular region 13 (fixing plate 12) and the outer fixing portion 23 with some play. As shown in the figure, the rotating shaft 14 to which the roller 11 is attached may use a bolt having a head on the outside, and the fixing plate 12 side may be fixed with a nut 16. Further, the nut 16 may be welded to the bolt (rotating shaft 14).

On the other hand, the roller 11 protrudes from the edge of the outer shell fixing plate 21 in the vertical direction in FIG. As a result, the slide body 10 can be appropriately slid when stored in the guide rail 30 (the situation of FIG. 5 described later).

FIG. 4 is a side view of the slide body 10 of FIG. 1 as viewed from the diagonally right side. On the virtual bisector of the central angle (center line H in FIG. 4), the distances to the four points, which are the mounting positions of the rotating shaft 14 on the rectangular region 13, are equal (center of the connecting portion 18). ) Is provided so as to cover the connection portion 17 with the object to be slid by the guide rail 30. In the embodiment shown in the figure, the fixed plate 12 is connected between the edges 15 and 15, but another joining form may be used as long as the arrangement is the same. The arrangement of the roller 11 and the rotation shaft 14 on the slide body 10 is also two-fold rotational symmetry with the connection portion center 18 of the connection portion 17 as the rotation center. It is also mirror-symmetric with respect to the bisector H passing through the center 18 of the connecting portion and the virtual plane perpendicular to the bisector H and passing through the center 18 of the connecting portion. By arranging the four rollers 11 in a rectangular shape so that the respective rotation axes 14 are oblique, the rollers 11 can easily hit the guide rail 30, but by further arranging the four rollers 11 with high symmetry with respect to the center 18 of the connection portion. , It becomes easier to move smoothly.

Of the structure of the slide body 10, it is preferable that the roller 11 is made of resin because it is slippery, but from the viewpoint of durability, a metal roller 11 may be used. Further, the other parts of the slide body 10 may be made of metal such as stainless steel which is hard to rust.

By sliding the inside of the guide rail 30, the slide body 10 for the guide rail can smoothly slide the object connected to the connecting portion 17 (preferably the center 18 of the connecting portion) along the guide rail 30. it can. The form when the slide body 10 is inserted into the guide rail 30 will be described with reference to FIGS. 5 to 7.

FIG. 5 is a vertical cross-sectional view of the guide rail 30 with respect to the slide direction, a slide body 10 introduced therein, and a guide bar 46 for a hanging curtain connected thereto. In the figure, W refers to the wall surface of the building to which the hanging curtain according to the embodiment described later is attached.

The guide rail 30 has an opening groove 31 along the sliding direction. What is connected (here, the guide bar 46) slides along the opening groove 31. The slide body storage portion 33 inside the opening groove 31 in which the slide body 10 is stored has a wider width than the opening groove 31, and both sides of the narrower opening groove 31 are retaining portions 32. The slide body 10 is prevented from coming off in the middle. That is, the width of the opening groove 31 is smaller than the distance between the rollers 11a, 11b (or 11c, 11d) of the slide body 10.

FIG. 6 is a cross-sectional view of the guide rail 30 along the sliding direction. In the hanging curtain device, it corresponds to the cross-sectional view in the vertical direction. Here, the figure at the time of introduction to the guide rail 30a provided on the left side facing the hanging curtain device is shown. The guide bar 46 slides up and down, and the roller 11 basically hits the retaining portion 32 and slides by rotating appropriately.

FIG. 7 is a view facing the opening groove 31 of the guide rail 30. The slide body 10 is a virtual diagram in which the guide bar 46 connected to the connecting portion 17 is cut off. Since the guide bar 46 is connected so as to be centered on the center 18 of the connecting portion, any of the rollers 11a to 11d is suitable without coming out of the opening groove 31 regardless of the direction in which the slide body 10 is tilted up, down, left or right. Can be slid up and down in the figure by hitting the inside of the slide body storage unit 33.

As shown in FIGS. 5 and 7, the guide rail 30 itself is fixed to the wall surface W in some way. In this embodiment, an L-shaped plate 34 fixed to the wall surface W with bolts 35 is attached, and an auxiliary plate 36 welded to the guide rail 30 is fastened to the L-shaped plate 34 with bolts 37.

FIG. 8 is a front view of the hanging curtain device 40 in which the slide body 10 is incorporated in the guide rail 30. The hanging curtain device 40 is a device capable of posting the contents described in the hanging curtain main body 41, which has a vertically long strip shape, on the wall surface W of the building. In the hanging curtain device 40 according to the present invention, the hanging curtain main body 41 can be smoothly stored and deployed by the action of the slide body 10. The guide rails 30a and 30b are attached in parallel to the left and right sides of the hanging curtain device 40. The guide rails 30a and 30b are oriented so that the opening grooves 31 face each other.

The hanging curtain main body 41 is fixed to the upper end side guide bar 46a whose upper end side is horizontally passed, and is fixed to the lower end side guide bar 46b whose lower end side is horizontally passed. As a form of fixing, for example, a ring-shaped fixing tool 47 welded to the side surface of the guide bar 46 (46a) and a fixing hole 45 made in the hanging curtain main body 41 may be fixed. The method is not limited.

Further, at least one place on the way, preferably a plurality of places, is fixed to the horizontally passed guide bar 46c. Either the upper end side guide bar 46a or the lower end side guide bar 46b is moved up and down by the elevating device, so that it can be stored and deployed. The guide bar 46c moves up and down according to its movement.

FIG. 8 shows an example in which the hoisting machine 43, which is an elevating device, is installed below. The lower end side guide bar 46b is fixed, and the upper end side guide bar 46a is movable. The hanging curtain device according to the present invention is not particularly limited by the position of the lifting device, and although not shown, the lifting device may be installed above, for example, the roof of a building. In the example shown in the figure, by winding the ropes 42a, 42b hooked on the pulleys 44a, 44b, 44c attached to the upper end of the hanging curtain device 40, the fixtures 47a, 47b attached to the upper end guide bar 46a are pulled up. The upper end side guide bar 46a is pulled up. As a result, the hanging curtain main body 41, which has been folded or rolled downward and stored, is unfolded. On the contrary, when the ropes 42a and 42b are unwound by the hoisting machine 43, the hanging curtain main body 41 is folded downward according to gravity.

During this vertical movement, when the upper end side guide bar 46a and the guide bar 46c move up and down, they move up and down according to the guide rail 30. A slide body 10 is attached to both bar ends 48a and 48b of the guide bars 46a and 46c, respectively. At the time of attachment, the connection portion center 18 is attached so as to be aligned with the axis center of the guide bars 46a and 46c.

FIG. 9 shows a situation in the vicinity of the slide body 10 when the guide bar 46 (upper end side guide bar 46a, lower end side guide bar 46b, guide bar 46c) deviates significantly from the horizontal when moving. Even in such a case, one or more of the rollers 11 (rollers 11c in the figure) can easily come into contact with the wall surface inside the slide body storage portion 33. And since the four rollers 11 are independent, the rotation is not blocked unlike the case of one large roller. Therefore, even if the guide bar 46 is tilted, the sliding can be continued without the vertical movement being caught there. As a result, it is possible to greatly reduce the possibility of being caught when the hanging curtain main body 41 is stored or deployed and having to be manually repaired on the wall surface of the building.

Further, since the slide body 10 cannot be pulled out by the retaining portion 32 of the guide rail 30, the four corners and various parts of the hanging curtain main body 41 can be fixed on the guide rail 30. As a result, the contents of the hanging curtain main body 41 are not greatly obscured by the wind.
