Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a shutter one-side down adjustment mechanism that adjusts one side down of either the left or right side of a shutter curtain that opens and closes a frontage opening.

[Conventional technology]

The shutter curtains used in conventional shutters are of the sectional slat type, in which U-shaped section slats of different sizes are fitted one after another, the panel connected type, in which flat panels are connected at the top and bottom, or the slats of the same size. There are slat types that connect the top and bottom. In each of the above-mentioned types of shutters, hanging members such as wire ropes and chains are attached to the mounting portions on both sides of the support member located at the bottom of the shutter curtain. On the other hand, in the upper housing part of the shutter curtain, a shaft with rotary bodies such as a winding drum and a sprocket fixedly fitted on both sides is suspended horizontally, and is linked to the rotation of the opening/closing machine. The vertical movement of the shutter curtain is caused by the rotation of a rotating body that is linked to the forward and reverse rotation of the shaft, and the hanging material is rolled up and rolled down to open and close the frontage opening.

By the way, the above-mentioned shutter curtain has a problem in that it slants down on either the left or right side when viewed from the front. The reason why the shutter curtain goes down one side is that because the shaft is long, it is impossible to accurately manufacture the keyways at the same positions on the left and right sides, and there are manufacturing tolerances and manufacturing errors. Here are some points that arise. In addition to this, assembly errors occur when assembling the shaft by inserting a key between a keyway formed on the rotating body that is fitted into the shaft and a keyway of the shaft.

Due to the above-mentioned manufacturing tolerances and assembly errors, the teeth tips of the left and right sprockets that fit on the shaft are not in the same position, and if the tips of one sprocket are used as a reference, the tips of the teeth of the other sprocket are at maximum 1/
A phase difference of 2 pitches will occur. For this reason, if a chain with a fixed pitch is suspended between the left and right sprockets, the link pitches will not be at the same horizontal level and the entire shutter curtain will tilt downward to either the left or right. The same is true when the rotating body is a winding drum; the length and attachment position of the wire rope are fixed, and the lengths of the wire ropes suspended from the left and right winding drums are not the same. ,
The shutter curtain connected to this will swing down to either the left or right.

In order to adjust the above-mentioned one-sided descent, for example, disengage the chain on the side where the one-sided descent is occurring, pull it up, send it one pitch backwards, and then mesh it to correct the link pitch misalignment of the left and right chains. Adjustments were made to maintain balance between the left and right sides of the shutter curtain. Further, in the case of a wire rope used in a winding drum, adjustment of one side of the rope has not been carried out because it is difficult due to the construction.

[Problem that the invention attempts to solve]

The phenomenon of the shutter curtain tilting one-sidedly is unavoidable due to the manufacturing process and assembly of the shaft and rotating body. However, if the one-sided adjustment is not performed, the shutter curtain will tilt to the left or right and the balance will not be maintained, which not only causes problems in terms of aesthetics, but also causes the end of the shutter curtain to touch the guy rail when opening and closing. There was a problem of rubbing and damaging the ends of the shutter curtain. In addition, due to the tilt of the shutter curtain as it falls one side, the ends of the shutter curtain become stuck with the guide rail, which poses a problem in that opening and closing of the shutter curtain becomes difficult.

Also, if the chain pitch is one of the sprockets,
Even if you adjust the length of the shutter curtain by a pitch and then pull up the chain on the lower side, it is impossible to finely adjust the length of the chain by less than 1/2 pitch, and the shutter curtain still remains on one side and is not fully adjusted. There was a problem in that one side downward adjustment was not performed to maintain left and right balance.

The object of this invention is to solve the above-mentioned problems and provide a mechanism for adjusting one side of the shutter curtain, which can adjust the one side of the shutter curtain and maintain left-right balance.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention has a shutter B in which hanging materials are attached to both sides of the support material at the bottom of the shutter curtain, and the opening surface is opened and closed by winding up and lowering the hanging materials. a fixing member having an inclined engagement surface formed thereon and having a lower end of the suspension member attached thereto is disposed below the support member;
A movable member whose lower surface has an inclined engagement surface having approximately the same inclination angle as the inclined engagement surface of the fixed member is interposed between the fixed member and the support member, and is moved by engaging with the fixed member and the movable member. This is a shutter one-side down adjustment mechanism that is equipped with an adjustment tool that allows the member to be moved.

[Effect]

With the shutter curtain's one-sided downward adjustment mechanism, the movable member is moved between the fixed member and the support member by operating the adjustment tool on the side where the one-sided downward movement of the shutter curtain occurs, or the opposite side where one-sided upward movement occurs. By sliding and moving between, the height relationship between the upper part of the moving member and the support material is changed by the amount of height movement of the engagement surface, and the support material on the downward side of one side is pushed up, or the support material on the upward side of one side is pushed up. Lower the support material to maintain balance between the left and right sides of the shutter curtain, and adjust the lowering of the shutter curtain on one side.

〔Example〕

An embodiment of this invention will be described based on the drawings.
Figure 1 of the drawings is a front view of the shutter equipped with a single-down adjustment mechanism, Figure 2 is an enlarged view of section C in Figure 1,
FIG. 3 is an exploded perspective view of the one-side downward adjustment mechanism.

As an example of the shutter B, a section slat type shutter curtain will be explained. The section slats 2 have a substantially U-shape in cross section with predetermined size differences, and when the shutter curtain 1 is opened with the opening side facing downward, the section slats 2 have larger dimensions and then smaller dimensions. It is designed to fit in. Further, the section slats 2 are arranged to be in a latched state when the shutter curtain 1 is extended by mutual latching portions (not shown) when the shutter curtain 1 is closed. A shutter curtain 1 is constructed by connecting a bottom section 3 which contacts the floor surface to the lowest part of the section slat 2. The bottom section 3 has a supporting member 4, which serves as a reinforcing member, attached in its longitudinal direction, and a single downward adjustment mechanism A is located at the bottom of both sides of this reinforcing member 4, and a wire rope 5, which is a hanging member, is attached to the bottom section 3. It's stuck.

On the other hand, above the shutter curtain 1, a shaft 11 is rotatably supported in conjunction with the operation of the opening/closing machine 10, and winding drums 12, which are rotating bodies, are arranged at both ends of the shaft 11. There is. The end of the wire rope 5 is fixed to a mounting portion at a predetermined position on the winding drum 12, and the wire rope 5 is wound in a straight line on the body so that it is wound spirally in the axial direction without overlapping. The rope groove is formed in a spiral shape.

The one-sided downward adjustment mechanism A is composed of a fixed member 13, a moving member 14, and a bolt 15, as shown in FIGS. 2 and 3. It should be noted that the single-down adjustment mechanisms A on both sides have the same configuration and are arranged symmetrically, so only one side will be explained as an example.

The fixing member 13 has two rectangular side plates 16, 16 arranged in parallel and fixed with a connecting piece 17 interposed between them. This side plate 16,
The upper surface of the shutter curtain 16 forms engaging inclined surfaces 18, 18 (hereinafter referred to as inclined surfaces), which are inclined downwardly (downward to the right in FIG. 2) outward in the width direction of the shutter curtain 1. is formed. The connecting piece 17 is fixed below the lower ends of the engaging surfaces 18, 18, and has a female thread 19 in the horizontal direction. Furthermore, the side plates 16, 16 are provided with four holes each at the same position, so that the fastening bolts 6 and nuts 7 can be inserted.
It is fastened with Further, through holes 8, 8 are formed in the center of the side plates 16, 16, and a wire fixing pin 9 is inserted and fixed into the through holes 8, 8, and the end of the annular wire rope 5 is locked. ing.

Furthermore, the movable member 14 has two rectangular side plates 20, 20 arranged parallel to each other at equal intervals to the parallel interval of the fixed member 13, and a connecting member 2 between them.
1 is fixed. The upper surfaces of the side plates 20, 20 are horizontally formed so as to contact the lower surface of the support member 4, and the lower surfaces have an engagement slope of the same angle to overlap the engagement surfaces 18, 18 of the fixing member 13. surface 18',
18' (hereinafter referred to as an inclined surface) is formed. Guide plates 22, 22 are provided on the outer surfaces of the side plates 20, 20 to prevent the moving member 14 from shifting in the lateral direction, which is perpendicular to the direction in which the engaging surfaces 18', 18' are formed.
is firmly attached. The connecting member 21 has its lower end portion projected downwardly from the side plates 22, 22 and is fixed thereto, and a longitudinal elongated hole 23 is formed in the projected portion. The position of this elongated hole 23 is determined by the position of the moving member 14.
When the engaging surfaces of the fixing member 13 and the fixing member 13 are overlapped with each other, the position coincides with the position of the female thread 19 of the connecting piece 17 in the fixing member 13.

Further, a bolt 15 serving as an adjustment tool is inserted between the moving member 14 and the fixing member 1 and passing through the long hole 23 of the moving member 14 and screwing into the female screw 19 of the fixing member 13.
3 is engaged. By operating this bolt 15, the movable member 14 moves along the engagement surfaces 18, 18 of the fixed member 13 over a range equivalent to the length of the elongated hole 23 of the movable member 14 (in the left-right direction in Fig. 2). ), thereby changing the height position of the upper surface of the moving member 14 up and down.

In the single downward adjustment mechanism A configured as described above, the wire rope 5 is locked to the fixed member 13, and the movable member 14 has its engagement surfaces 18', 18' of the fixed member 13, 18, and its upper surface is placed in contact with a cushion rubber 24 attached to the lower surface of the support member 4 in the bottom section 3. Therefore, if a downward slope occurs as shown by the imaginary line in Fig. 2, operate the bolt 15 of the downward slope adjustment mechanism A on the side where the downward slope occurs to adjust the height corresponding to the amount of downward slope. In contrast, by moving the movable member 14 from the right side to the left side in the figure, the support member 4 on that side is pushed up, so the left and right balance of the shutter curtain 1 is maintained and the one-sided downward movement is adjusted. .

[Effect of idea]

Since this invention is constructed as described above, by operating the side-down adjustment mechanism on the side where the side-down is occurring, it is possible to adjust the side where the one-side down is occurring over a fine adjustment range, and the shutter can be adjusted. This allows the left and right sides of the curtain to be balanced.

As a result of the above, the shutter curtain will not be tilted, so when opening and closing the shutter curtain, the ends of the shutter curtain will not rub the guide rail and damage the ends of the shutter curtain, and the ends of the shutter curtain will not be in a tilted state. There is no longer a problem where the guide rail gets jammed and causes problems when opening and closing.
