Description

  The present invention relates to an on-roof fixture that is attached to the top of a corrugated roof.

  Generally, various devices and members such as a television antenna, an air conditioner, a solar cell panel, a heat insulating sheet, etc. are disposed on the top surface of a corrugated roof such as a folded plate roof (angular corrugated roof) or a round corrugated roof. Conventionally, various on-roof fixtures for attaching these devices and members on the roof have been proposed (for example, see Patent Document 1).

  In particular, at the top of the peak portion of the corrugated roof in which the peaks and valleys are alternately continuous, the overlapping portion of the overlapping roof materials is connected and fixed by screwing upward bolts and nuts. In the roof, the roof has a structure in which the shaft portion of the upward bolt for connecting the roofing material that protrudes from the roof through the overlapped portion is sandwiched and fixed by sandwiching pieces with opposite ends. An upper fixture has also been proposed.

  This on-roof fixture is, for example, fastened to both leg pieces with tightening bolts and nuts penetrating laterally through both leg pieces of a sandwiching tool formed in a substantially portal shape, and facing from the lower ends of both leg pieces. It has a structure in which both of the sandwiching pieces extending to are clamped to the upward bolt. Therefore, since the front end of the sandwiching piece is fixed in a state of being bitten into the thread groove of the shaft portion of the upward bolt, there is no possibility that the roof mounting tool is easily detached.

  Moreover, although the thing of patent document 1 is comprised from a pair of clamping member with which the clamping tool was fulcrum-coupled, this kind of thing is applied to the structure which clamps both clamping pieces to an upward volt | bolt. In the same manner, there is no possibility that the on-roof fixture is easily detached.

Japanese Patent No. 3368374

  However, in the case of an on-roof fixture of a type that is attached by being clamped to an upward bolt, there are the following problems.

  14A and 14B are schematic explanatory views showing two examples of attachment examples of a conventional roof mounting tool to be attached to the corrugated roof, and FIG. 14A is a side edge of the corrugated roof Y. FIG. FIG. 14 (b) is an example of clamping to the upward bolt B in the lap joint structure. FIG. 14 (b) is an example of clamping to the leg part D1 of the goby part D formed by the seam type joining at the top part Y1a of the peak part Y1. . Both are examples in which the heat insulating sheet 110 is fixed and attached above each roof mounting tool 100, and both examples use the roof mounting tool 100 of the same type and the same structure.

  As described above, when the heat insulating sheet 110 is fixed and stretched around the roof-mounted fixtures 100, the heat insulating sheet 110 may be dampened by rainwater or the like, and then contracted when dried. Then, if the heat insulating sheet 110 is firmly fixed to the roof mounting tool 100, the roof mounting tool 100 disposed on both sides of the heat insulating sheet 110 is pulled to the center by the shrinkage of the heat insulating sheet 110, and There is a possibility that the sandwiching piece 101 sandwiched between the part D and the upward bolt B slides up.

  In this case, although there is a possibility that a slight shift may occur in the case mounted on the goby portion D, the upper part of the gouge portion D protrudes in the lateral direction, and thus there is no possibility that the roof mounting tool 100 comes out of the goze portion D. (See FIG. 14 (a)), in the case where it is attached to the upward bolt B, the roof mounting tool 100 is gradually tilted by a strong tensile force, and the tip of the sandwiching piece 101 connects the shaft portion B1 of the upward bolt B. There is a possibility that it may come off while sliding up (see FIG. 14B).

  Therefore, the roof mounting tool 100 of the type that is mounted by clamping to the upward bolt B as described above has a structure that is mounted with a stronger clamping force than that to be mounted on the gouge portion D. .

  The present invention has been proposed in view of such circumstances, and the purpose thereof is a pinching piece that can be strongly attached to an upward bolt projecting from a top surface of a corrugated roof through a pedestal and fixed to the upward bolt. An object of the present invention is to provide an on-roof fixture that is not likely to come off due to external force.

In the roof mounting fixture that is fixedly attached to the top of the corrugated roof, an upward bolt protrudes from the top surface of the corrugated roof via a mountain seat, and the tip of the sandwich piece The upper portion of the corrugated roof is formed with a locking portion that can be locked to the upward bolt and an insertion portion formed on the upper and lower sides, and a pair of clamping pieces are brought close to each other. When, with it is inserted between the mountain seat, characterized in that so as to sandwiched the shaft portion of the upward bolt the locking portion.

In the on-roof fixture according to claim 2, the waterproof packing is interposed between the top of the corrugated roof and the mountain seat, and the insertion portion has a packing accommodating recess that avoids a conflict with the waterproof packing. Is formed.

The roof-mounted device according to claim 3, the locking portion is provided with a lockable locking recess on the outer peripheral surface of the shaft portion of the upward bolt.

  In the on-roof fixture according to claim 4, the sandwiching tool is integrally formed including a leg piece formed by bending the sandwiching piece at the lower end and an upper plate having the leg pieces at both ends, and a pair of legs. A pair of clamping pieces are brought close to each other by tightening the pieces.

  In the on-roof fixture according to the fifth aspect, the sandwiching tool is configured by connecting a pair of sandwiching members in which sandwiching pieces are bent at the lower ends thereof so that they can be opened and closed.

  In the on-roof fixture according to claim 6, the clamping member has a bolt through hole formed in the center, an upper plate in which a cut groove extending from the bolt through hole to one side edge is formed, and a base end of the upper plate It consists of a leg piece that extends further downward and a sandwich piece that extends from the lower end of the leg piece in substantially the same direction as the upper plate, and the sandwiching tool has the upper plates of the two sandwich members facing each other. In this state, the upper plate's slits are inserted into each other so that the top ends of the top plates are positioned below the base end of the mating top plate. The holes are made to coincide with each other, the clamping tool fastening bolts are passed through the matched bolt through holes, and the fastening nuts are screwed together so that the tips of the clamping pieces are brought close to each other.

  The present invention has the following effects.

According to the on-roof fixture according to claim 1, the sandwiching tool brings a pair of sandwiching pieces close to each other, and the insertion portion formed at the tip of the sandwiching piece is located between the top of the corrugated roof and the mountain seat. Since it is a structure to be inserted into the head, that is, a mounting structure in which the clamping piece of the clamping tool is hooked and locked on the mountain seat, there is almost no possibility that the clamping tool will come off. Moreover, since it has the attachment structure which clamps the latching | locking part of the clamping piece to the axial part of an upward volt | bolt, the clamping by an insertion part can be supplemented. And, by these two types of upper and lower multiple stages of locking, it is possible to reliably prevent the sandwiching piece from being detached from the upward bolt by an external force.

According to the roof-mounting device according to claim 2, since the insertion portion packing accommodating recess to avoid conflict with the waterproof packing is formed, a top of the waveform roof insertion portion sandwiching member, mountain seat The insertion portion is not likely to come into contact with the waterproof packing so that the waterproof packing is deformed, and the waterproof packing can be prevented from being damaged.

  According to the on-roof fixture according to claim 4, the sandwiching tool is integrally formed including the leg piece formed by bending the sandwich piece at the lower end and the upper plate having the leg piece at both ends. For this reason, the sandwiching tool can be constructed in a sturdy and simple shape. Moreover, since it is integrally formed, there is no possibility that a deviation occurs between the both sandwiched pieces. Further, since the pair of leg pieces are tightened to bring the pair of sandwich pieces close to each other, a tightening structure can be realized simply by providing a tightening bolt or the like for tightening the pair of leg pieces. Can be simple.

  According to the roof mounting tool according to claim 5, the sandwiching tool is configured by connecting a pair of sandwiching members in which the sandwiching pieces are bent at the respective lower ends so as to be openable and closable, By operating the force point, the sandwiching piece as the action point can be operated.

  Hereinafter, embodiments of a roof mount according to the present invention will be described with reference to the drawings.

  FIG. 1 is an explanatory view of a first embodiment of a roof fixture according to the present invention, and FIG. 1 (a) is a perspective view showing a state before the roof fixture is attached to a corrugated roof, FIG. FIG. 1B is a developed plan view of a portion surrounded by a broken line in FIG. 2A, 2B, 3C, and 3D are partial cross-sectional front views showing a construction state of the on-roof fixture shown in FIG.

  2A is a partial cross-sectional front view showing a state before the roof mounting fixture A is attached to the corrugated roof, and FIG. 2B is an attachment of the roof mounting fixture A to the upward bolt of the corrugated roof. FIG. 3C is a partial cross-sectional front view showing a state in the middle, FIG. 3C is a partial cross-sectional front view showing a state where the roof mounting fixture A is attached to the upward bolt of the corrugated roof, and FIG. The partial cross-section front view which shows the state which further attached various apparatuses and the members E to the fixture A is shown, respectively.

  The details will be described below.

  Examples of the corrugated roof to which the on-roof fixture A is attached include the folded plate roof Y (angular corrugated roof) and the round corrugated roof shown as examples. Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

  The folded plate roof Y shown as an example is a roof in which mountain portions Y1 and valley portions Y2 are alternately continuous, and a plurality of folded plate roof materials are polymerized at the top portion Y1a of the mountain portion Y1 on the side edge, It has a lap-type joining structure in which the upward bolt B and the nut B2 are screwed together at the overlapping portion. Further, in order to prevent water from entering from the bolt hole, a waterproof packing C1 is attached between the nut B2 and the top Y1a, and further, a mountain seat covering the waterproof packing C1 between the nut B2 and the waterproof packing C1. C is provided.

  Further, on the back side of the folded plate roof Y, a support fitting Y3 for bolting, which is substantially the same shape as the folded plate roof Y in a front view, is attached. In addition, the attachment position of the upward bolt B for attaching the rooftop fixture A is not limited to the joint portion of the adjacent folded plate roof material, and the upward bolt B may be attached to the other top portion using the support fitting Y3.

  The on-roof fixture A is made of a metal plate or a hard resin plate, and is attached to and fixed by sandwiching the above-mentioned upward bolt B for connecting the overlapping portion protruding upward from the top Y1a of the folded plate roof Y. It has become.

  Specifically, the roof mounting fixture A is formed by bending the top plate 11, a pair of leg pieces 12 extending downward from both ends thereof, and the lower ends of the leg pieces 12 so that the tips are opposed to each other. The sandwiching piece 13 is integrally formed with a substantially gate-shaped sandwiching tool 1, and both leg pieces 12 are fastened so that the tips of the sandwiching pieces 13 are close to each other, and the upward bolt B It is structured to be sandwiched between. The tightening of the leg pieces 12 is performed by screwing the tightening bolts 25 penetrating through the shaft holes 12 a provided in the opposing leg pieces 12 and the tightening nuts 26. Further, in the center of the upper plate 11, a sword point bolt 3 or the like similar to the upward bolt B is erected so that various devices and members E (see FIG. 3D) can be attached.

At the tip of the sandwiching piece 13, a locking portion 15 and an insertion portion 14 that can be locked to the upward bolt B in two ways are formed in two steps in the vertical direction. By making the piece 13 approach, the insertion portion 14 is inserted between the top portion Y1a of the folded roof Y and the mountain seat C, and the upper locking portion 15 is clamped to the shaft portion B1 of the upward bolt B. It is like that.

These locking portions 14 and 15 are formed by bending the tip of the sandwiching piece 13, and the insertion portion 14 has a shape in which the center of the tip is cut out in a curved shape, and the upper locking portion 15 has a shape having a locking protrusion 15a protruding obliquely upward. As shown in the developed plan view of FIG. 1B, these locking portion 14 and insertion portion 15 are formed by partially cutting, bending, and cutting up a plate piece, and are easily formed. It is something that can be done. In addition, the broken line in FIG.1 (b) has shown the return part.

Each of the insertion portions 14 of the pair of sandwich pieces 13 is configured by a tip end portion of the sandwich piece 13 and is inserted below the mountain seat C so as to be opposed to each other and hooked and locked to the mountain seat C. . In addition, the curved packing housing recess 14a at the distal end forms a space when the distal end of the insertion portion 14 is inserted below the mountain seat C and close to each other, and the waterproof packing C1 is accommodated in the space. (See each enlarged plan view in FIGS. 2B and 3C). In addition, in each enlarged plan view of FIG.2 (b) and FIG.3 (c), the waterproof packing C1 is shown by the cross hatching of a broken line.

Thus, since the insertion part 14 is a structure which penetrates the downward direction of the mountain C, once it latches, it will not remove | deviate to the extent that the clamping tool 1 is pulled from upper direction or pressed from right and left.

It should be noted that the distal ends of the insertion portions 14 are preferably in contact with each other, but a slight gap may be formed as long as the insertion portions 14 are locked so as to be hooked at least on the mountain seat C. In addition, the packing accommodating recess 14a prevents contact with the waterproof packing C1, but some contact is allowed as long as the waterproof packing C1 is not elastically contracted or damaged by pressing. The

Further, as shown in the enlarged plan view around the insertion portion 14 and the locking portion 15 surrounded by a broken line in FIG. 1A, a locking recess 15c is formed at the center of the tip of the sandwiching piece 13, and the central portion thereof is formed. Are formed with two slits 15d. The upper locking portion 15 is a total of three pieces, that is, a locking protrusion 15a sandwiched between the cut grooves 15d and protruded by cutting the plate piece upward, and both inner edge pieces 15b that are not raised, It is comprised so that the axial part B1 of the upward volt | bolt B can be latched.

  That is, since the engagement portion 15 made of such three pieces is formed at the upper end at the tip of the sandwiching piece 13, the engagement portion 15 makes the engagement with the outer peripheral surface of the shaft portion B 1 of the upward bolt B. Each piece of the locking portion 15 consisting of six left and right total pieces facing the space formed by the two locking recesses 15c can be bitten into the screw groove on the outer peripheral surface of the shaft portion B1 of the upward bolt B and sandwiched.

According to such a locking structure, the locking portion 15 formed on the upper and lower stages, clamping force by the insertion portion 14 becomes strong, therefore, upward clipping piece 13 is sandwiched upward bolt B is the external force There is no risk of detachment from the bolt B.

Further, the clamping force by the upper locking portion 15 is combined with the clamping force of the insertion portion 14 to obtain a strong clamping force. The upper locking portion 15 may have a structure in which the inner edge piece 15b is not locked to the thread groove of the upward bolt B, and only the locking protrusion 15a is locked to the thread groove and sandwiched.

Moreover, in order to give stronger clamping force, you may form the latching | locking part of 3 steps | paragraphs or more at the front-end | tip of the clamping piece 13 by bending and raising. Even in that case, only the insertion portion 14 is inserted and locked between the top Y1a of the folded plate roof Y and the mountain seat C, and the two or more upper locking portions are attached to the shaft portion B1 of the upward bolt B. Lock.

  The on-roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

  First, the shaft portion 25a of the tightening bolt 25 is penetrated from one of the shaft holes 12a of the both leg pieces 12, and the tightening nut 26 is lightly tightened from the distal end side of the tightening bolt 25 to be in a temporarily fixed state. The upward bolt B is inserted and inserted through the gap S between the both sandwiching pieces 13 from above the upward bolt B erected on the roof Y (see FIG. 2A).

Next, when the tightening bolt 25 and the tightening nut 26 that have been temporarily fixed are tightened, both the leg pieces 12 are brought close to each other by the tightening force, and both the sandwiching pieces 13 are also brought close to each other, as shown in FIG. As shown in the enlarged plan view of the mountain C portion surrounded by a broken line, the insertion portion 14 provided at the tip of the sandwiching piece 13 is inserted between the top Y1a and the mountain C, and is attached to the mountain C. It is in a state of being hooked and locked, and further inserted and the tip of the insertion portion 14 comes into contact with each other. At the same time, the upper locking portion 15 is locked in the screw groove on the outer peripheral surface of the shaft portion B1 of the upward bolt B. The upward bolt B is clamped (see FIGS. 2B and 3C).

At this time, due to the proximity of the insertion portions 14, the packing housing recess 14 a is united to form one space, and the waterproof packing C <b> 1 is disposed in the space (see the enlarged plan view of FIG. 3C). ).

  Various devices and members E can be attached above the upper plate 11 of the rooftop fixture A thus attached to the folded plate roof Y by means of a sword bolt 3 or the like standing on the upper plate 11 (FIG. 3 ( d)).

As described above, according to the on-roof fixture A of the present invention, as described in the present embodiment, it can be fixed to the upward bolt B protruding from the folded roof Y with two kinds of upper and lower locking structures. It is possible to reliably prevent the sandwiching piece 13 from being detached from the upward bolt B by an external force. In particular, since the insertion portion 14 has a mounting structure that is hooked and locked to the mountain seat C, there is almost no possibility that the clamping tool 1 is detached, and the upper locking portion 15 is clamped to the shaft portion B1 of the upward bolt B. Since it is the mounting structure to be made, the clamping by the insertion part 14 can be supplemented.

  Further, the sandwiching tool 1 is integrally formed including the leg piece 12 formed by bending the sandwiching piece 13 at the lower end and the upper plate 11 having the leg pieces 12 at both ends. 1 can be constructed in a sturdy and simple shape. Moreover, since it is integrally formed, the possibility of deviation is low. Further, since the pair of leg pieces 12 are tightened to bring the pair of sandwiching pieces 13 close to each other, it is only necessary to use a tightening bolt 25 or the like for tightening the pair of leg pieces 12. Can be simplified. In addition, since it is also possible to make the upper plate 11 into a flat shape without standing the sword bolt 3, the upper portion of the upper plate 11 can be used in various modes.

  FIG. 4 is a perspective view showing another construction example of the on-roof fixture A, and FIG. 5 is a partial cross-sectional front view after the roof-top fixture A is attached to the folded plate roof Y in the construction example. FIG.

  Here, the parts common to FIGS. 1 to 3 are denoted by the same reference numerals, overlapping description is omitted, and only different points will be described below.

  That is, in this construction example, a round goby projecting in a substantially circular cross section on the upper surface of the folded plate roof Y as a connecting structure of the folded plate roof Y using the on-roof fixture A shown in FIGS. It shows what is connected by a goby part D of the mold. In addition, since it is the same also about the square goby etc. which protruded in the cross-section substantially L shape on the upper surface of the folded-plate roof Y, description about a square goby etc. is abbreviate | omitted.

Specifically, when the roof mounting fixture A of the present invention is attached to the goby portion D, it is not locked by the insertion portion 14 and the locking portion 15, but is formed in two stages of the sandwiching pieces 13. The front end portion 13a is attached to the leg portion D1 formed on the goby portion D of the folded plate roof Y.

Therefore, the roof mounting fixture A has a structure having upper and lower engaging portions 15 and insertion portions 14 for being sandwiched by the upward bolts B, but the top portion Y1a is formed on the top portion Y1a by the goby joint. It can be installed without any problems. Of course, since there is the goby portion D, the on-roof fixture A is not likely to come off.

  Next, a second embodiment will be described.

  FIG. 6 is an explanatory view of the second embodiment of the rooftop fixture according to the present invention, and is a perspective view showing a state before the rooftop fixture is attached to the corrugated roof. FIG. 7 is an exploded perspective view of the roof mounting tool. 8 (a), 8 (b), 9 (c), and 9 (d) are partial cross-sectional front views showing a construction state of the on-roof fixture shown in FIG.

  8A is a partial cross-sectional front view showing a state before the roof mounting fixture A is attached to the corrugated roof, and FIG. 8B is an attachment of the roof mounting fixture A to the upward bolt of the corrugated roof. FIG. 9C is a partial cross-sectional front view showing a state in the middle, FIG. 9C is a partial cross-sectional front view showing a state where the roof mounting fixture A is attached to the upward bolt B of the corrugated roof, and FIG. The partial cross-sectional front view which shows the state which further attached various apparatuses and members E to the upper fixture A is shown, respectively.

  As the corrugated roof to which this on-roof fixture A is attached, the folded plate roof Y (angular corrugated roof) and the round corrugated roof shown as examples are mentioned as in the first embodiment. Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

  Further, the folded plate roof Y, which is the attachment target of the on-roof fixture A, is the same as the folded plate roof Y shown in the first embodiment, and the structure thereof is denoted by the same reference numerals and description thereof is omitted. To do.

This on-roof mounting tool A constitutes a sandwiching tool 1 ′ by connecting a pair of sandwiching members 10 so as to be openable and closable, and a pair of opposing sandwiching pieces that are the working points of the sandwiching tool 1 ′. 13 is a fixture having a structure in which 13 is fixed close to each other and clamped by an upward bolt B protruding from the top Y1a of the folded plate roof Y. The top Y1a of the folded plate roof Y is attached to the tip of the sandwiched piece 13. into which an insertion portion 14 between the lockable locking portion 15 and the top Y1a and mountain seat C upward bolt B projecting on the upper surface of, and is formed in two stages in the vertical direction.

First, regarding the entire structure of the sandwiching tool 1 ′, which is a feature of the present invention, excluding the sandwiching structure to the upward bolt B by the two types of locking portions 15 and the insertion portion 14 provided at the tip of the sandwiching piece 13. explain.

  Each of the pair of sandwiching members 10 constituting the sandwiching tool 1 ′ has an upper plate 11 in which a bolt through hole 11 e is opened at the center and a cut groove 11 d is formed from the bolt through hole 11 e to one side edge. The leg piece 12 is bent from the base end of the upper plate 11 and extends downward, and the sandwiching piece 13 extends from the lower end of the leg piece 12 in substantially the same direction as the upper plate 11.

  The sandwiching tool 1 ′ is arranged such that the top ends of the top plates 11 are arranged below the base end of the top plate 11 of the mating member with the top plates 11 of the two sandwich members 10 facing each other. Next, the slits 11d of the upper plate 11 are inserted into each other so that both the upper plates 11 are swingably engaged with each other so that the bolt through holes 11e are aligned with each other. By passing the bolts 21 and screwing the tightening nuts 22, the ends of the sandwiching pieces 13 are brought close to each other.

  Here, as shown in the figure, a rounded round head bolt may be used as the clamping tool clamping bolt 21. As the clamping nut 22, a nut 22a rotates on the top surface of a hat-shaped washer 22b. A nut with a washer attached freely may be used. The bolt stop 23 is made of synthetic resin or the like, and a plurality of cuts 23b are formed on the periphery of the hole 23a.

  Summarizing the above structure, the two clamping members 10 are connected to each other in a crossing manner by a cut groove 11d formed in the upper plate 11, and two upper members from above and below are clamped by a clamping tool clamping bolt 21 and a clamping nut 22. By tightening the plate 11, the tip of the upper plate 11 serving as a power point is expanded with the cut groove 11 d as a fulcrum, and the two upper plates 11 in an intersecting state are made closer to a flat plate shape, thereby both acting as the action points. It has a deformed scissor structure in which the sandwiching pieces 13 are brought close to each other.

  More specifically, as shown in FIG. 7, the upper plate 11 includes a flat base end portion 11a, a step portion 11c formed on the front end side of the base end portion 11a, and a step portion 11c. Furthermore, a distal end portion 11b formed on the distal end side and located at a position lower than the base end portion 11a by about one sheet thickness is provided. In addition, a long hole extending across the base end portion 11a and the front end portion 11b around the stepped portion 11c is provided at substantially the center of the upper plate 11, and this long hole constitutes the bolt through hole 11e. Furthermore, a presser claw 11f cut and raised downward is formed at the end of the long hole on the tip 11b side. The cut groove 11d communicating with the bolt through hole 11e is formed along the step portion 11c. It is desirable that the upper plate 11 has a gentle forward inclination as a whole.

  In this way, the stepped portion 11c is formed along the bolt through hole 11e and the cut groove 11d provided in the center of the upper plate 11, so that when the front end portion 11b of the upper plate 11 is opened, the step 2c is polymerized. The upper plate 11 of the sheet is substantially flat, and the gap between the base end portion 11a of the upper plate 11 and the distal end portion 11b of the upper plate 11 of the counterpart clamping member 10 becomes smaller, and there is no possibility of wobbling. , A more stable shape can be obtained.

  According to such an on-roof fixture A, the sandwiching tool 1 'is composed of the two sandwiching members 10, and they are connected to the fulcrum so that they can be opened and closed. When the nut 22 is in a loose state, the two clamping members 10 are also in a loose state. Therefore, in order to fix the sandwiching piece 13 in the closed state, it is only necessary to fasten the fastening nuts 22 to fix the upper plates 11 together, and the workability is good.

  Next, a structure for sandwiching the upward bolt B by the sandwiching piece 13 of the roof mounting fixture A, which is a feature of the present invention, will be described.

At the front end of the sandwiching piece 13, a locking portion 15 and an insertion portion 14 that can be locked by two types of locking structures are formed in two steps in the vertical direction. Specifically, the front end of the sandwiching piece 13 has a two-stage plate formed by folding back a plate piece, and the insertion part inserted between the top Y1a of the folded-plate roof Y and the mountain seat C on the lower stage. 14 is formed, and a locking portion 15 that can be locked to the outer peripheral surface of the shaft portion B1 of the upward bolt B is formed in the upper stage.

That is, the structures of the upper and lower two types of the locking portion 15 and the insertion portion 14 are the same as those of the on-roof mounting tool A of the first embodiment, and the same effects are produced. The enlarged plan view around the locking portion 15 is the same as that shown in FIG.

Further, since the on-roof fixture A is composed of a sandwiching tool 1 ′ composed of two sandwiching members 10, when the sandwiching piece 13 is brought close to the sandwiching object 13 in the absence of a sandwiching target, the bolt penetration of the upper plate 11 is performed. There is a possibility that the tips of both sandwiching pieces 13 may be displaced in the horizontal direction due to play or the like formed in the hole 11e, but the structure in which the shaft portion B1 of the upward bolt B is locked and clamped by the upper locking portion 15. Therefore, as long as the upward bolt B is a target to be clamped, there is no possibility that such a shift occurs. Even if the upward bolt B is clamped in a state where there is a slight shift, the shift does not increase because the upward bolt B is fitted in the locking recess 15c. In other words, the upper locking portion 15 can prevent the occurrence of a subtle shift that cannot be prevented by the insertion portion 14.

  The on-roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

  First, in the state where both the sandwiching pieces 13 of the sandwiching tool 1 ′ are sufficiently opened in the on-roof mounting tool A, that is, the two fasteners are loosened by loosening the fastening bolts 21 and the fastening nuts 22. The member 10 is connected to a fulcrum so that it can be opened and closed, and the upward bolt B is inserted from above the upward bolt B erected on the folded plate roof Y through the gap S between the sandwiching pieces 13 (FIG. 8A). )).

Next, when the clamping tool clamping bolt 21 and the clamping nut 22 that have been temporarily fixed are tightened, the upper plates 11 that are overlapped in a swingable and loose state are flattened. At the same time, both sandwiching pieces 13 extending from the lower ends of both leg pieces 12 are also close to each other, and as shown in the enlarged plan view of the mountain seat C surrounded by the broken line in FIG. The insertion portion 14 provided at the distal end of the insertion portion is inserted between the top portion Y1a and the mountain seat C so that the mountain seat C is hooked and locked. Further, the insertion portion 14 is inserted between the distal ends of the insertion portion 14 (clasp piece 13). And the upper locking portion 15 is locked in the thread groove on the outer peripheral surface of the shaft portion B1 of the upward bolt B to clamp the upward bolt B (FIGS. 8B and 9C). )reference).

At this time, due to the proximity of the insertion portions 14, the packing housing recess 14 a is united to form one space, and the waterproof packing C 1 is disposed in the space (see the enlarged plan view of FIG. 9A). ). In addition, in each enlarged plan view of FIG.8 (b) and FIG.9 (a), the waterproof packing C1 is shown by the cross-hatching of a broken line.

As described above, the insertion portion 14 is formed with the packing accommodating recess 14a that avoids the conflict with the waterproof packing C1, so that the waterproof packing C1 is deteriorated and damaged by attaching the clamping tool 1 'to the upward bolt B. Can be prevented.

  Various devices / members E can be attached above the upper plate 11 of the rooftop fixture A thus attached to the folded plate roof Y by the clamping tool fastening bolts 21 and the like standing on the upper plate 11. (See FIG. 9 (d)).

As described above, according to the on-roof fixture A of the present invention, as described in the present embodiment, it can be fixed to the upward bolt B protruding from the folded roof Y with two kinds of upper and lower locking structures. It is possible to reliably prevent the sandwiching piece 13 from being detached from the upward bolt B by an external force. In particular, since the insertion portion 14 has a mounting structure in which the insertion portion 14 is hooked and locked to the mountain seat C, there is little possibility that the clamping tool 1 ′ is detached, and the upper locking portion 15 is clamped by the shaft portion B 1 of the upward bolt B. Since it has a mounting structure for wearing, it is possible to supplement the clamping by the insertion portion 14.

  FIG. 10 is a perspective view before installation showing another example of construction on the roof mounting tool A, and FIG. 11 is a partial cross-sectional front view showing a construction state of the roof mounting tool A shown in FIG. .

  In this construction example, using the on-roof fixture A shown in FIGS. 6 to 9, as a connecting structure of the folded plate roof Y, a round goby type projecting in a substantially circular cross section on the upper surface of the folded plate roof Y. It shows what is connected by the goby part D.

  About this construction example, the structure of the upper and lower two types of locking portions 15 and 14 formed at the tip of the sandwiching piece 13 and the structure of the entire sandwiching tool 1 ′ are the same as those shown in FIGS. In addition, since the sandwiching structure of the sandwiching piece 13 with respect to the goby portion D is the same as that shown in FIGS. 4 and 5 of the first embodiment, the description of the detailed structure and effects is omitted. .

  Next, a third embodiment of the on-roof fixture A according to the present invention will be described with reference to FIG. FIG. 12 is a schematic explanatory view showing the embodiment, and FIGS. 12A and 12B are schematic front views showing a construction state.

This on-roof mounting tool A constitutes a sandwiching tool 1 ′ by connecting a pair of sandwiching members 10 so as to be openable and closable, and a pair of opposing sandwiching pieces that are the working points of the sandwiching tool 1 ′. 13 are fixed in close proximity to each other and are clamped by an upward bolt B protruding from the top Y1a of the folded plate roof Y. The top of the top Y1a of the folded plate roof Y is attached to the tip of the sandwiched piece 13. it is obtained by forming a insertable 14 between the upward bolt B to be locked a locking portion 15 and the top Y1a and mountain seat C that protrudes on the upper surface.

  Specifically, the roof mounting fixture A is different from the above-described embodiment in that the operation piece 17 that is a power point is above the fulcrum, and is connected in an intersecting manner as in the above-described second embodiment. A leg piece 12 and a sandwiching piece 13 extend below the fulcrum. Then, the clamping piece 13 can be clamped to the upward bolt B by clamping the operation piece 17 with the clamping bolt 25, the clamping nut 26, and the like. Various devices and members can be attached to the operation piece 17 of the roof mounting fixture A thus attached.

Note that the upper and lower locking portions 15 and the insertion portion 14 formed at the front end of the sandwiching piece 13, which is a characteristic part of the present invention, have the same structure as that of the above-described embodiment. Description of is omitted.

Next, another example of the upper and lower locking portions 15 and the insertion portion 14 formed at the front end of the sandwiching piece 13, which is a main part of the roof mounting fixture A of the present invention, will be described.

  FIG. 13 is an explanatory view of another embodiment, FIG. 13 (a) is a schematic partial cross-sectional front view of the roof mounting fixture A, and FIG. 13 (b) is a perspective view of the distal end portion of the sandwiching piece 13.

In this embodiment, the upper and lower locking portions 15 and the insertion portion 14 are formed at the tip of the sandwiching piece 13 so that the sandwiching piece 13 itself is formed in two stages in the vertical direction.

  That is, the roof mounting fixture A has the center portion of the lower end portion of the leg piece 12 cut and raised, and the center portion is divided into the upper part and the both side parts are divided into the lower part. The two upper and lower locking portions are formed in parallel.

Thus, according to the structure which isolate | separates the clamping piece 13 up and down, the fixture A on a roof can be manufactured cheaply, without increasing material. In this example as well, the insertion portion can be inserted and locked between the top portion and the mountain seat, and the plurality of upper locking portions can be locked to the shaft portion B1 of the upward bolt B.
