The winding device 21 has a mode in which one of a winding operation and a feeding operation is electric and the other is manual, a mode in which both operations are manual or electric, and the one operation is a biasing force such as a spring. Any mode, such as a mode in which the process is performed, may be used.
[0025]
The lower frame 30 is a substantially horizontally long plate member that is formed in a downwardly inclined shape with the upper surface 31 facing outward, and guide rails 40 are formed substantially vertically on both ends of the upper surface 31 in the longitudinal direction. The abutment surface is provided between the left and right guide rails 40, 40 on the upper surface 31 so as to abut the seat plate member 11 of the opening / closing body 10 when closed. The lower frame 30 is fixed on a lower frame (not shown) on the housing side of a building or the like, and drains rainwater or the like sprayed on the surface of the opening / closing body 10 to the outside by the downwardly inclined upper surface 31. To do.
[0026]
Each guide rail 40 is a member processed into a long shape between the storage case 20 and the lower frame 30 by drawing or extruding an aluminum alloy material, bending a steel plate or other metal plate, or the like.
[0027]
The guide rail 40 has a guide recess 41 for inserting the end of the opening / closing body 10 in the width direction on the inner surface side of the bottom 43 facing the end of the opening / closing body 10 in the width direction and guiding the opening / closing body in the opening / closing direction of the opening / closing body. And the auxiliary recessed part 42 which orient | assigned the opening to the same direction as this guide recessed part 41 is arranged in parallel substantially (refer FIG.1 and FIG.4).
[0028]
The guide recess 41 has a substantially U-shaped cross section composed of the first piece 41a and the second piece 41b disposed substantially parallel to the opening / closing body thickness direction at a predetermined interval, and the bottom 43. Present.
In addition, according to the example of illustration, the 1st piece part 41a is arrange | positioned in the housing body side (lower side according to FIG. 4) in the opening-and-closing body opening / closing direction, and the 2nd piece part 41b is 1st piece part 41a and Arranged on the outer side of the housing (upper side according to FIG. 4) at a predetermined interval.
Moreover, the length of the opening / closing body width direction of the 1st piece part 41a and the 2nd piece part 41b is set substantially equal.
[0029]
And the guide recessed part 41 forms the to-be-engaged parts 40a and 40a for engaging the relaxation member 60 in the both inner surfaces which face the opening / closing body 10. FIG.
Each engaged portion 40a protrudes in a substantially C-shaped cross section toward the front or back surface of the opening / closing body 10, and the opening / closing body from the end portion (the lower end portion according to FIG. 3) of the guide rail 40 in the opening / closing body closing direction. It extends continuously over the end side in the opening direction.
[0030]
And the relaxation member 60 is fitted by each engaged part 40a over the opening-and-closing body opening-and-closing direction.
The relaxing member 60 is brought into contact with and elastically deforms the opening / closing body 10 and the guide rail 40 when the opening / closing body 10 is in an opening / closing operation or fluttered due to wind pressure. This is a member that prevents frictional contact and collision between the front and back surfaces of the opening / closing body 10 by preventing general contact. According to a preferred example of the present embodiment, the relaxation member 60 has a portion protruding toward the front surface or the back surface of the opening / closing body 10 in a brush shape that can be elastically bent.
[0031]
Further, on the end portion side (the lower end side in the illustrated example) of the bottom portion 43 in the guide recess 41 in the opening / closing body closing direction, a key having a substantially triangular shape in side view capable of engaging the key bar 11a of the seat plate member 11 is provided. The receiving member 44 is fixed (see FIG. 1).
[0032]
Next, the auxiliary recess 42 will be described in detail. The auxiliary recess 42 includes the second piece 41b and a third piece disposed substantially parallel to the second piece 41b at a predetermined interval. The portion 42a has a substantially concave shape in cross section formed by connecting the bottom portion 43, and is provided in a range extending over the substantially entire length of the guide recess 41 in the opening / closing body opening / closing direction.
[0033]
And this auxiliary | assistant recessed part 42 forms the said 3rd piece part 42a longer in the opening-and-closing body width direction than the said 2nd piece part 41b.
That is, the auxiliary recess 42 is configured so that the edge 42a1 on the protruding end side (left end side in FIG. 4) of the third piece 42a is opened and closed more than the edge 41b1 on the protruding end side of the second piece 41b in the guide recess 41. The dimension x is projected to the center in the width direction (left direction in FIG. 4).
Therefore, as shown in FIG. 2A, the dimension w1 between the edges 42a1 and 42a1 of the auxiliary recesses 42 and 42 in the left and right guide rails 40 and 40 is the dimension w2 between the edges 41b1 and 41b1 of the guide recess 41. Smaller than.
[0034]
The dimension x is between the bottom surface 43 of one (left side according to FIG. 2) guide rail 40 and the edge 42a1 of the third piece 42a of the other (right side according to FIG. 2) guide rail 40. It is preferable to set the width dimension w3 to be smaller than the width dimension w4 of the opening / closing body 10. According to this configuration, even if the opening / closing body 10 pulled out from the guide recess 41 is moved toward one side in the width direction between the left and right security recesses 42, 42, the end on the other side corresponds to the corresponding crime prevention It can be made difficult to come off from the recess 42.
[0035]
Further, as shown in FIG. 4, the opening / closing body thickness direction interval y2 in the auxiliary recess 42 (in other words, the interval y2 between the second piece portion 41b and the third piece portion 42a) The opening / closing body 10 is thicker than the thickness y3 so that it can be inserted, and the guide is provided so that the opening / closing body 10 when inserted is not easily pulled outward (upward in FIG. 4) in the opening / closing body thickness direction. It is preferable to set it smaller than the interval y1 in the opening / closing body thickness direction in the recess 41 (in other words, the interval y1 between the first piece portion 41a and the second piece portion 41b).
That is, the auxiliary recess 42 does not need to have the function of guiding the opening / closing body 10 in the opening / closing direction like the guide recess 41, and therefore the distance y <b> 2 is reduced to the extent that the opening / closing body 10 can be inserted, and is separated from the guide recess 41. The opening / closing body 10 when inserted is formed so as to be close to or in contact with the front and back surfaces of the opening / closing body 10 when inserted.
[0036]
Next, the effect by the guide rail structure A1 of the said structure is demonstrated in detail.
When, for example, a jig or the like is hung on the center side in the width direction of the opening / closing body 10 in the closed state, the center side is forcibly pulled outward (upward in FIG. 2) in the opening / closing body thickness direction. The body 10 bends in a substantially arcuate shape so that the center side bulges outward.
Then, since the width w4 (see FIG. 2A) of the opening / closing body 10 becomes narrower as the width w4 ′ in FIG. 2B, one end portion or both end portions in the width direction of the opening / closing body 10 correspond. The opening is extracted from the guide recess 41 outward in the thickness direction of the opening / closing body, and the extracted end portion is inserted into the auxiliary recess 42 by the restoring force when the opening / closing body 10 bent in a substantially arcuate shape is restored. Inserted and engaged (state shown in FIG. 2C).
Further, when the wind pressure is received from the outer side (upper side in FIG. 2), for example, on the center side in the width direction of the opening / closing body 10 in the closed state, the opening / closing body 10 causes the center side to move toward the center side by a reaction against the wind pressure. In some cases, one end part or both end parts in the width direction are pulled out outward from the corresponding guide recesses 41 in the opening / closing body thickness direction so as to bulge outward. Also in this case, as described above, the end portion of the opening / closing body 10 that has been extracted is inserted into the auxiliary recess 42 by the restoring force when the opening / closing body 10 bent in a substantially arcuate shape is restored. (The state shown in FIG. 2C).
The opening / closing body 10 in this engaged state has the edge 42a1 of the auxiliary recess 42 protruding toward the center of the opening / closing body 10 rather than the edge 41b1 of the guide recess 41. Even if wind pressure is applied to the center side, it does not easily come off from the auxiliary recess 42.
In addition, as shown in FIG. 3, the opening / closing body 10 in this engaged state is formed between the portion 10a inserted into the auxiliary recess 42 and the portion 10b remaining in the guide recess 41. Since both end portions 10c and 10c in the width direction are sandwiched between the edge portions 41b1 and 41b of the second piece portions 41b and 41b in the left and right guide rails 40 and 40, further outward (see FIG. 3 is prevented from moving to the left) and moving in the opening / closing body opening direction (upward according to FIG. 3).
Therefore, the opening / closing body 10 can be maintained in a highly crime-proof state that is difficult to be pulled out further outward than the auxiliary recess 42 and is not easily opened.
Moreover, since the opening / closing body 10 is difficult to flutter due to the wind pressure, the occurrence of noise due to the flapping of the opening / closing body 10 deviated from the guide recess 41, the contact of the opening / closing body 10 with a fluttering, etc. Can be prevented.
Therefore, according to the guide rail structure A1 of the present embodiment, it is possible to improve the crime prevention and wind resistance of the switchgear.
[0037]
Next, a guide rail structure A2 for an opening / closing device as another example of the present invention will be described. In addition, in the following structure, about the location substantially the same as the opening-and-closing apparatus A mentioned above and the guide rail structure A1 of an opening-and-closing apparatus, the detailed description which overlaps is abbreviate | omitted by attaching | subjecting the same code | symbol.
[0038]
The guide rail structure A2 shown in FIG. 5 has the same shape on the inner surface of the third piece 42a constituting the auxiliary recess 42 in addition to the both engaged portions 40a and 40a on the inner surface of the guide recess 41 in the guide rail 40 described above. An engaged force 42a2 is provided, and the reinforcing member 70 is fixed to the engaged portions 40a, 40a, and 42a2 so that the expanding force in the opening / closing body thickness direction acts on the guide recess 41 and the auxiliary recess 42. When it does, it tries to counter the expansion force.
[0039]
The reinforcing member 70 is made of a metal member having a relatively high bending strength, such as a steel material or a stainless steel material. The substantially flat engagement portions 72, 73, 74 are integrally formed on one side of the substantially flat bottom portion 71. Standing up.
In the reinforcing member 70, the engaging portions 72, 73, and 74 are inserted into the engaged portions 40a, 40a, and 42a, respectively, from the opening / closing body closing direction side.
Each of the engaged portions 40a, 40a on the guide recess 41 side engages the reinforcing member 70 on the end side in the opening / closing body closing direction of the guide rail 40, and the opening / closing body opening direction is more than the reinforcing member 70. The above-described relaxation member 60 is engaged with the side.
[0040]
According to this guide rail structure A2, when the opening / closing body 10 is pulled outward in the thickness direction, when the expanding force in the opening / closing body thickness direction acts on the guide recess 41 and the auxiliary recess 42, the expansion is performed. It is possible to suppress the guide rail 40 from being deformed by the opening force.
Therefore, according to this guide rail structure A2, it is possible to prevent the opening / closing body 10 from being pulled out of the guide recess 41 and the auxiliary recess 42 by deforming the guide recess 41 and the auxiliary recess 42.
[0041]
In the above-described guide rail structure A2, the reinforcing member 70 is a member that crosses and is fixed to the guide recess 41 and the auxiliary recess 42 so as to counter the external force in the expanding direction of the guide recess 41 and the auxiliary recess 42. The configuration and shape are not limited.
[0042]
Further, the means for fixing the reinforcing member 70 to the guide concave portion 41 and the auxiliary concave portion 42 is not limited to the above embodiment. For example, the engaging portions 72, 73, and 74 of the reinforcing member 70 are connected to the guide concave portion 41. In addition, the guide recess 41 may be fixed to the inner surface, the outer surface, the end surface, or the like by welding, screwing, riveting, or the like.
[0043]
Further, the position of the reinforcing member 70 in the opening / closing body width direction is not limited to the illustrated example. However, in order to effectively suppress the spreading force, the guide recess 41 and the auxiliary member 70 can be used as shown in the illustrated example. It is preferable that the concave portion 42 is disposed near the edge portions 41b1 and 42a1.
[0044]
Further, the guide rail structure A1 has a structure in which only the guide recess 41 is reinforced by omitting the engaged portion 42a2 of the guide rail 40 and the engaging portion 74 of the reinforcing member 70, or the reinforcing member 70. By omitting the engaging portion 72, it is possible to reinforce only the auxiliary recess 42.
[0045]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
According to the present invention, when the central side in the width direction of the opening / closing body for the opening / closing device in the closed state is pulled in either the inside or outside direction in the opening / closing body thickness direction, the opening / closing body bends in a substantially arcuate shape, Even if the end of the opening / closing body in the width direction of the opening / closing body has been extracted from the guide recess of the guide rail, the extracted end of the opening / closing body tries to return to its original state from the bent state Due to this restoring force, it is inserted and engaged in the auxiliary recess.
In this engaged state, the opening / closing body has an end in the width direction of the opening / closing body between the portion inserted in the auxiliary recess and the portion left in the guide recess in the opening / closing body. Therefore, the movement in the opening / closing body width direction and the movement in the opening / closing body opening direction are hindered.
Therefore, even when the opening / closing body is further pulled, the opening / closing body is hardly pulled out from the auxiliary recess and is not easily opened.
Therefore, by preventing the opening / closing body from being drawn out in the thickness direction and being inappropriately opened, it is possible to provide a guide rail structure for an opening / closing device with improved crime prevention.
[0046]
Further, as a further invention , the crime prevention property is further improved by disposing an auxiliary recess on the end side in the closing direction of the opening / closing body, which is a part that is easily pulled in the opening / closing body thickness direction as compared with other parts. be able to.
[0047]
Further, as a further invention, of both edges in the opening / closing body thickness direction constituting the auxiliary recess, the edge on the opposite side to the guide recess is used as the edge on the auxiliary recess constituting the guide recess. If the end in the width direction of the opening / closing body is forcibly extracted from the guide recess, the end engages with the auxiliary recess. Even if the engaged open / close body is forcibly pulled so as to be pulled out from the auxiliary recess, it is blocked by the edge of the auxiliary recess protruding from the edge of the guide recess toward the center in the width direction of the open / close body. Therefore, it is not easily extracted.
[0048]
As a further invention, the auxiliary recess is adjacent to the guide recess if the auxiliary recess is provided adjacent to the guide recess in a range extending over the entire length of the guide recess in the opening / closing body opening and closing direction . When the end of the opening / closing body in the width direction is forcibly extracted from the guide recess, it is immediately engaged in the auxiliary recess.
Moreover, since the auxiliary recess is provided in a range extending over the substantially entire length of the guide recess in the opening / closing body opening / closing direction, the end in the width direction of the opening / closing body is extracted from the guide recess at any part in the opening / closing body opening / closing direction. Even so, the extracted portion is engaged in the auxiliary recess.
