Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pressure-resistant roller of a panel shutter, and more specifically, to a panel that can be opened and closed even when the shutter curtain is under strong surface pressure. The present invention relates to a pressure resistant roller of a shutter.

[Conventional technology]

The panel shutter is a shutter curtain formed by vertically connecting a chain of panels with guide rollers at both ends to form a shutter curtain, and the shutter curtain is moved up and down along the left and right guide rails erected on both sides of the building opening. I am trying to let you.

And since the panel shutter does not generate unpleasant noise when the shutter curtain is opened and closed, and it is also aesthetically pleasing, it has a wide range of uses and has a strong surface pressure such as the opening of an air film structure building. The number of cases where a panel shutter is installed in the receiving area is increasing.

However, in the conventional panel shutter, when a strong surface pressure is applied, each panel is pressed against the inner side of the guide rail or the lintel, which causes frictional resistance in close contact with each other, and as a result, the vertical movement of the panel is hindered. There was a problem.

[Problems to be solved by the invention]

The invention of the present application was devised in order to solve such a problem, and an object thereof is to enable an opening / closing operation even when the shutter curtain of the panel shutter is under a strong surface pressure.

[Means for solving problems]

The technical means adopted by the present invention to achieve such an object are:
Both ends of the shutter curtain, which is projected on the left and right of each panel and is connected in series in a chain with roller shafts with guide rollers pivotally attached to the tips at predetermined intervals in the vertical direction, on both sides of the building opening It is a panel shutter that is inserted into an upright guide rail so that it can be moved up and down, and when opened, it moves upward from the uppermost panel in order to move upward from the adjacent lower panel to open the opening, and the rolling surface of the guide roller. The clearance between the front and rear inner wall surfaces of the guide rail is smaller than the clearance between the front and back surfaces of the panel and the front and rear inner wall surfaces of the guide rail, and at least the uppermost panel is connected to the lower left and right end surfaces and the panel in the vertical direction. Between the chains, a pressure-resistant roller is pivotally supported on the panel end face with the rolling surface thereof protruding from the front and back surfaces of the panel.

[Action]

Since the invention of the present application is configured as described above, when the shutter curtain is pressed to one side by the surface pressure, the pressure resistant roller and the guide roller pivotally supported by the panel located at the top contact the inner surface on the low pressure side of the guide rail. Therefore, the pressure-resistant roller and the guide roller bear the surface pressure received by the panel. Therefore, even when the panel is subjected to surface pressure, the uppermost panel can be supported and lifted by the pressure resistant roller and the guide roller. As a result, a gap is created between the uppermost panel and the panel located below it, and air is communicated between the inner and outer surfaces of the panel to create an equal pressure, and the lifting of the panel located below does not receive surface pressure. Can be done in the state.

〔Example〕

The present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 1 is a horizontal cross-sectional view of an end portion of the panel shutter S. The panel shutter S includes a shutter curtain in which roller shafts 9a provided at upper left and right end portions of the panel 1 are vertically connected by a chain (not shown). It is a panel shutter that can be moved up and down along guide rails 2 that are erected on both sides of the opening 4, and that when opened, the opening is opened while sequentially separating from the uppermost panel. The guide rail 2 has an inner wall surface 24 on which the guide roller 9 rotatably supported on the tip end side of the roller shaft 9a sandwiches the chain, and the roller shaft 9a of the panel 1.
It is formed by an inner wall surface 23 on which the pressure-resistant roller 10 having a diameter larger than the expected width of the panel 1 rolls, which is axially supported on the lower end surface, and the rolling surface and inner wall surface of the guide roller 9.
The clearance with 24 is set smaller than the clearance between the front and back surfaces of panel 1 and inner wall surface 23. In this embodiment, the guide rail 2 is composed of a portion 21 fixed to the skeleton 3 and a separation portion 22 detachably attached to the fixed portion, and the separation portion 22 is supported by the support member 5. Reference numeral 6 is a finishing member that covers the space 7 around the support portion 5, and 8 is a seal rubber for an airtight structure between the guide rail 2 and the panel 1. In the figure, 4A is the high pressure side, 4B
Is on the low voltage side.

FIG. 2 shows details of the pressure roller 10, (a) is a front view,
(B) is a side view. The pressure-resistant roller 10 is assembled by rotatably fitting the roller body 11 to the shaft support plate 12 via a ball bearing, and using the flange 13 as a seat to assemble the end portion of the panel 1. After the protrusion 18 provided on the frame member 17 is aligned with the positioning hole 14, it is attached to the screw hole 15 using a fixing screw. The pressure roller 10 has a diameter slightly smaller than the groove width of the guide rail 2 and slightly larger than the thickness of the panel body 1,
The rolling surface is pivotally supported in a state of protruding from the front and back surfaces of the panel 1. The pressure resistant roller 10 is provided at least at a lower portion of the uppermost panel body 1. Since the pressure roller 10 is provided on the end surface of the panel 1 as described above, the panel 1
It does not interfere with the operation of the chain when moving up and down.

FIG. 3 is a schematic side view of the airtight panel shutter,
The panel 1 is connected vertically by a chain C,
An airtight means 50 including a seal rubber 51 and a seal edge 52 is provided at the overlapping portion of the upper and lower panels 1. In this figure, the uppermost panel and the panel connected below it are shown. FIG. 3 (a) shows that when the opening is fully closed,
Shows the state where the panel 1 receives the surface pressure P, and the chain C
Has a play of length. Here, if the panel 1 can be lifted by the amount of play of the chain C, the seal edge 52 separates from the seal rubber 51 as shown in FIG. 3B, and both sides of the panel become equal in pressure.

In the present invention, since the pressure resistant roller 10 is provided at least at the lower part of the uppermost panel 1, when the shutter curtain formed by vertically connecting the panels 1 is pressed to one side by the surface pressure, the pressure curtain 10 is raised above the panel 1. The guide roller 9 which is axially supported and the pressure-resistant roller 10 which is axially supported below the panel 1 come into contact with the inner wall surfaces 24 and 23 of the guide rail 2 on the low pressure side, respectively, so that the panel 1 can be directly pressed against the guide rail 2. Absent. Therefore, even when the panel 1 receives the surface pressure P, the uppermost panel 1 can be lifted, and as a result, a gap is formed between the upper and lower panels 1 and the airtight structure is released. , Both sides of the panel 1 are equalized in pressure, and it is easy to lift each panel. Further, since the pressure resistant roller is located between the lower parts of the left and right end surfaces of the panel 1 and the chain connecting the panels in the vertical direction, it does not hinder the lifting and lowering of the chain.

Further, when the pressure-resistant roller 10 is provided on all the panels 1, the panel body 1 can be more easily lifted even in the case of strong winds, and the panel 1 has the guide roller 9 and the pressure-resistant roller when the opening 4 is closed. As a result of being supported by two points of 10, the displacement of the panel 1 as shown in FIG.

FIG. 4 shows an airtight structure between the panel 1 and the lintels 31 and 31A above the panel shutter S.

One or two upper pressure-resistant rollers 40 are provided in the middle of the lengthwise direction in the vicinity of the upper edge of the uppermost panel 1. As shown in FIG. The support shaft 42 is pivotally supported between the brackets 43, 43. The uppermost panel 1 receives a surface pressure that causes warpage in the lengthwise direction, but the upper pressure-resistant roller 40 has the lintels 31, 31.
The surface of the panel 1 is prevented from frictioning with the lintel 31 or the like by coming into contact with any one of A.

[Effect of device]

According to the present invention, both ends of a shutter curtain formed by projecting right and left above each panel and connecting a roller shaft pivotally attached to a leading end of a guide roller with a chain in a vertical direction at predetermined intervals are connected to each other at both ends of a building. A panel shutter which is inserted into guide rails installed upright on both sides of the opening so that it can be moved up and down, and when opened, moves upward from the uppermost panel in order to move upward from the adjacent lower panel to open the opening. The clearance between the rolling surface and the front and rear inner wall surfaces of the guide rail should be smaller than the clearance between the front and back surfaces of the panel and the front and rear inner wall surfaces of the guide rail. The pressure-resistant roller is pivotally supported on the panel end faces with the rolling surfaces protruding from the front and back surfaces of the panel between the chains connected in the same direction. Even if the strong surface pressure is applied to over the curtain, without panels located at the top is pressed directly guide rails, the panel is lifted while being supported by the guide rollers and pressure rollers.
When the top panel is hoisted, a gap is created between it and the panel located below it, and air communicates with the inner and outer surfaces of the panel to create an equal pressure, so the subsequent panel hoisting is not subject to surface pressure. Can be done in the state. Therefore, by adopting the present invention, it is possible to install the panel shutter without trouble even when a strong surface pressure is applied to the opening of a building having an air film structure.
