JP5847866B2 - Cover stopper for mesh tray - Google Patents

Description

  The present invention relates to a mesh tray cover stopper used when fixing a cover to an opening of a mesh tray.

  Conventionally, when installing a cover on a cable rack, a cover stopper as described in Patent Document 1 has been proposed. This cover stopper has a latching hole having a latching hole formed in a bent side surface of the rack cover, and latched to the latching hole from the inside. A hook body having a locking portion to be locked is screwed with a fastening bolt.

  In wiring work for installing solar cell panels, a wiring tray called a mesh tray may be used instead of the cable rack. This mesh tray is a wire structure rack using steel wire rods, and enables lighter construction than a cable rack. By attaching a cover to the opening of the mesh tray, dust can be prevented from entering the tray, UV deterioration of the cable exterior can be prevented, or temperature rise in the tray can be prevented.

  However, since this mesh tray is different from the cable rack from the shape of the tray to the shape of the cover, it is impossible to use the conventional cover stopper for the cable rack. Therefore, for example, as shown in FIG. 6, a stopper 100 or the like that is engaged with the master bar P <b> 1 of the tray P is currently used.

  The stopper 100 is inserted into the stopper 100, which is locked to the master bar P1 of the tray P, from below, and the stopper bolt 110 is inserted into the connecting hole Q1 opened in the cover Q. The wing nut 120 is screwed to the locking bolt 110 on the upper surface of the cover Q (see FIG. 6).

No. 4-36180

  However, since the conventional fastener 100 has a structure in which a part of the fastener 100 is only locked to the main reinforcement P1 of the tray P, there is a possibility that the cover may be removed due to an outdoor wind pressure or the like. Moreover, in order to fix the cover Q, the stopper 100 and the locking bolt 110 are operated inside the tray P, and the locking bolt 110 is inserted into the connecting hole Q1 opened in the cover Q with one hand. Since the operation of screwing the wing nut 120 to the locking bolt 110 with the other hand is necessary while keeping it, a lot of labor is required for fixing the cover Q.

  Therefore, the invention was created to solve the above-mentioned problems, and the fixing work of the cover to be attached to the mesh tray becomes extremely simple, and even if a load such as strong wind or snow is applied to the cover installed outdoors, the cover is provided. An object of the present invention is to provide a mesh tray cover stopper that can firmly hold the fixed state.

In order to achieve the above object, the first means in the present invention is a cover stopper for fixing the cover Q to the opening of the mesh tray P.
A lower side surface portion 11 extending from the lower side of the main muscle P1 disposed along the longitudinal direction of the opening of the mesh tray P to the lower surface of the cover Q, and an upper side surface portion 12 extending from the upper side of the main muscle P1 to the upper surface of the cover Q. And the sandwiching body 10 is constituted by the connecting portion 13 that connects the upper side surface portion and the lower side surface portion in a swingable manner,
The parent muscle P1 and the longitudinal side edge of the cover Q overlaid on the parent muscle P1 are sandwiched from above and below by the sandwiching body 10, and from above the bolt insertion hole 12A opened in the upper side surface portion 12, the cover Q The upper side surface portion 12 and the lower side surface portion 11 are screwed with the fixing bolt 20 that penetrates the connecting hole Q1 that is opened in the upper portion.

  The second means is that a burring tap 14 is formed on the lower side surface portion 11, and the bolt of the upper side surface portion 12 when the parent muscle P1 and the cover Q are sandwiched from above and below by the sandwiching body 10. It is provided so that the position of the burring tap 14 overlaps the position of the insertion hole 12A.

In the third means, the lower side surface portion 11, the upper side surface portion 12, and the connecting portion 13 are integrally formed of a bendable metal material,
The lower side surface portion 11 has a band plate shape, bends both side edges at a position orthogonal to the parent muscle P1 upward to form a reinforcing piece 11A, and the upper surface of the lower side surface portion 11 on the parent muscle P1 side. And a locking rib 11B for locking the parent muscle P1 along the parent muscle P1,
A structure in which, when the master muscle P1 and the cover Q are sandwiched from above and below by the sandwiching body 10, the master muscle P1 is disposed between the end of the reinforcing piece 11A and the locking rib 11B. It is.

  According to the first aspect of the present invention, the master muscle P1 and the longitudinal side edge of the cover Q superimposed on the master muscle P1 are sandwiched from above and below by the sandwich body 10 and the cover Q and the sandwich body 10 are fixed through. Since the clamp body 10 is configured to be screwed with the bolt 20, the cover Q is not removed unless the clamp body 10 and the parent muscle P1 are broken. Therefore, the cover Q can be fixed extremely firmly.

  Moreover, the cover Q can be temporarily fixed to the parent muscle P1 simply by sandwiching the parent muscle P1 and the longitudinal side edge of the cover Q superimposed on the parent muscle P1 from above and below with the sandwiching body 10. As a result, it is possible to temporarily fix the cover Q to the parent muscle P1 and then fix the sandwich body 10 and the cover Q with the fixing bolt 20. As a result, the fixing operation can be made more efficient than the conventional fixing operation in which the locking bolt is held with one hand and the wing nut is screwed to the locking bolt with the other hand as in the conventional case.

  Further, since the longitudinal side edge of the cover Q is fixed to the main reinforcing bar P1 of the mesh tray P, even if the size of the mesh tray P is different and the width of the corresponding cover is changed, the cover fixing metal fitting is securely fixed. be able to.

  As in claim 2, when the parent muscle P1 and the cover Q are sandwiched from above and below by the sandwiching body 10, the position of the burring tap 14 overlaps the position of the bolt insertion hole 12A of the upper side surface portion 12. Since the cover Q is temporarily fixed to the main muscle P1 by the sandwiching body 10, the work of fixing the fixing bolt 20 to the burring tap 14 through the connecting hole Q1 from the bolt insertion hole 12A of the upper side surface portion 12 is performed. It became possible to carry out very efficiently.

  That is, after temporarily fixing the plurality of sandwiching bodies 10 in accordance with the connecting holes Q1, it is possible to screw the fixing bolts 20 continuously to the burring taps 14 using an electric screwdriver or the like. Thus, the troublesome fixing work such as the cover fixing metal fitting is not required, and the cover Q can be fixed extremely reasonably.

  As in claim 3, when the main muscle P1 and the cover Q are sandwiched from above and below by the sandwiching body 10, the main muscle P1 is arranged between the end of the reinforcing piece 11A and the locking rib 11B. With this configuration, the position of the sandwiched body 10 temporarily fixed to the parent muscle P <b> 1 can be prevented from shaking left and right. Therefore, the work at the time of screwing the fixing bolt 20 through the connection hole Q1 of the cover Q can be made efficient.

  Further, since the locking rib 11B locks the parent muscle P1 along the longitudinal direction of the parent muscle P1, the sandwiching body 10 fixed to the parent muscle P1 with the parent muscle P1 as the rotation axis is covered with the cover Q. It is also possible to swing up and down. From this, after fixing only one side of the cover Q, the cover Q can be lifted from the one side not fixed. Therefore, it is not necessary to remove all the cover Q even when wiring is increased, and the wiring work after the cover Q is fixed can be rationalized.

It is a sectional side view of the use condition which shows one Example of this invention. (A) thru | or (c) is a side view which shows the mounting | wearing procedure of this invention. It is a sectional side view which shows the other example of use of this invention. It is a side view which shows the conventional cover stopper metal fitting.

  According to the present invention, the fixing work of the cover attached to the mesh tray becomes extremely simple, and the cover fixed state can be firmly held even when a load such as strong wind or snow is applied to the cover attached outdoors. The initial objectives such as were achieved.

  Examples of the present invention will be described below. The cover fixing metal fitting of the present invention is a metal fitting for fixing the cover Q to the opening of the mesh tray P, and is composed of a sandwiching body 10 and a fixing bolt 20 (see FIG. 1). The mesh tray P is a mesh-like tray in which steel wires are combined, and a plurality of parent bars P1 that reinforce the structure such as the bottom and the opening are disposed along the longitudinal direction of the mesh tray P. The illustrated cover Q has a rectangular shape and has a structure strengthened by folding the longitudinal both side edges inward. Further, the shape of the cover Q can be arbitrarily changed, for example, the side edges of the long side are bent into a substantially L shape.

  The sandwich body 10 is a member attached to the main muscle P1 disposed in the opening of the mesh tray P, and includes a lower side surface portion 11, an upper side surface portion 12, and a connecting portion 13 (see FIG. 2). . And the fixing bolt 20 which penetrates the upper side surface part 12 and the cover Q of this clamping body 10 is screw-fixed to the lower side surface part 11 (refer FIG. 3).

  The lower side surface portion 11 is a portion from the lower side of the parent muscle P1 to the lower surface of the cover Q, and the upper side surface portion 12 is a portion from the upper side of the parent muscle P1 to the upper surface of the cover Q. A bolt insertion hole 12 </ b> A through which the fixing bolt 20 is inserted is opened in the upper side surface portion 12. The connecting portion 13 is a portion that connects the lower side surface portion 11 and the upper side surface portion 12 so as to be swingable on the parent muscle P1 side, and these constitute an integrated body 10 (see FIG. 1). ).

  This sandwiching body 10 is configured so as to sandwich the parent muscle P1 disposed along the opening of the mesh tray P and the longitudinal side edge of the cover Q stacked on the parent muscle P1 from above and below. Yes (see FIG. 1). Then, the upper side surface portion 12 and the lower side surface portion 11 are screwed from above the bolt insertion hole 12A of the upper side surface portion 12 with a fixing bolt 20 that penetrates the connecting hole Q1 opened in the cover Q (see FIG. 3). ).

  A burring tap 14 is formed on the lower side surface portion 11 shown in the figure (see FIG. 2). Then, when the main muscle P1 and the cover Q are sandwiched from above and below by the sandwiching body 10, the position of the burring tap 14 overlaps with the position of the bolt insertion hole 12A of the upper side surface portion 12. (See FIG. 3). The fixing bolt 20 passes through the bolt insertion hole 12A and the connecting hole Q1, and is then screwed to the burring tap 14. A nut may be fixed to the upper surface of the lower side surface portion 11 instead of the burring tap 14 (not shown).

  In the illustrated sandwiched body 10, the lower side surface portion 11, the upper side surface portion 12, and the connecting portion 13 are integrally formed of a bendable metal material (see FIG. 2). Furthermore, the lower side surface portion 11 has a band plate shape, and both side edges at a position orthogonal to the parent muscle P1 are bent upward to form a reinforcing piece 11A (see FIG. 2). In the illustrated example, a reinforcing piece 11 </ b> A is formed by integrating side edge portions formed on the front circular portion from both side edges of the lower side surface portion 11. Further, the reinforcing piece 11A of the lower side surface portion 11 is configured to face the reinforcing piece 12B formed on the peripheral side edge of the upper side surface portion 12, and the fixing strength by the sandwiched body 10 is increased (see FIG. 2). .

  On the other hand, a locking rib 11B that locks the parent muscle P1 along the parent muscle P1 protrudes from the upper surface of the lower side surface portion 11 on the parent muscle P1 side (see FIG. 2). Then, when the master muscle P1 and the cover Q are sandwiched from above and below with the sandwiching body 10, the master muscle P1 is arranged between the end of the reinforcing piece 11A and the locking rib 11B ( (See FIG. 3).

  When the cover Q is fixed, the parent muscle P1 is disposed between the end of the reinforcing piece 11A and the locking rib 11B. Therefore, if only one side of the cover Q is fixed, the cover Q is lifted from one side that is not fixed. (See FIG. 5). Therefore, even when additional wiring is added after the wiring has already been completed, it is not necessary to remove all the sandwiching bodies 10 fixing the cover Q, and the cover Q can be removed simply by removing the sandwiching body 10 on one side. It can be lifted and expanded.

  FIG. 4 shows a method for temporarily fixing the cover Q by the sandwiched body 10. First, when the opening portion of the mesh tray P is covered with the cover Q, the longitudinal side edge of the cover Q is disposed on the parent muscle P1 of the opening portion (see FIG. 5A). Next, the sandwich body 10 that is opened up and down is inserted from the direction of the outer surface of the parent muscle P1 to a position where the parent muscle P1 and the cover Q are sandwiched from the upper and lower sides (see (b) in the figure). At this time, the main reinforcement P1 is disposed between the end of the reinforcing piece 11A and the locking rib 11B. Subsequently, the upper side surface portion 12 and the lower side surface portion 11 are pressed from above and below to temporarily fix the cover Q to the parent muscle P1 (see FIG. 3C). At this time, the bolt insertion hole 12A of the upper side surface portion 12 and the connection hole Q1 of the cover Q are temporarily fixed while being aligned.

  After this temporarily fixed state, the fixing bolt 20 is inserted into the connecting hole Q1 from the bolt insertion hole 12A and screwed to the burring tap 14 (see FIG. 3). As a result, the cover Q is fixed to the parent muscle P1 (see FIG. 1).

  In addition, the structure of this invention is not limited to the example of illustration, The design change in the range which does not change the summary of this invention is arbitrary for the structure of the clamping body 10 and the fixing bolt 20. FIG.
