Description

  The present invention relates to a hook mounting structure.

  Houses are equipped with eaves that receive rainwater flowing down from the roof, and eaves that are connected to the eaves via a water collector or call and guide the rainwater collected in the eaves to the drain. A gutter is installed. In order to install the heel on the outer wall of a house or the like, a heel support for supporting and fixing the heel to the outer wall is fixed to the outer wall, and the heel is fixed to the heel support.

Conventionally, as a saddle support tool, an annular band portion that is attached so as to be wound around the outer peripheral surface of the saddle and fastens and holds the saddle and a fixing portion that fixes the band portion to the outer wall is provided. Is frequently used.
However, since this type of scissor support has an annular band exposed on the outer peripheral surface of the scissors and may impair the appearance, in recent years it is possible to fix and support the scissors without compromising the appearance. There has been proposed a scissor mounting structure including a scissor support.

  For example, in the scissor mounting structure disclosed in Patent Document 1, the scissors have a mounting rib that protrudes outward from the outer peripheral surface and includes a bulging locking portion at the tip and extends in the axial direction of the scissors. It is formed and is fixed to the outer wall of the house or the like, and is supported by the outer wall of the house or the like by being fixed to the heel support having the insertion groove into which the mounting rib is inserted.

Since this heel support supports the heel by inserting the mounting rib into the insertion groove, the band portion provided in the conventional heel support is unnecessary, and the heel support is supported. Since it is hidden behind the bag in the state where it is, the bag support is not exposed and the appearance is not impaired.
In addition, when attaching the collar to the outer wall of a house or the like, the work of inserting the mounting rib into the insertion groove may be performed instead of the conventional work of winding and fixing the band portion around the outer periphery of the collar. It can be attached efficiently and efficiently.

  However, in the above conventional scissor mounting structure, the mounting rib having a T-shaped cross section provided on the scissors is not expected to be elastically deformed, and the scissor support is elastically deformed to fit the mounting rib. Therefore, the heel support is greatly elastically deformed, and the heel support may be damaged during attachment or removal.

  Moreover, when manufacturing the cage | basket provided with an attachment rib, it shape | molds by extrusion molding, for example, water is poured to the cage | basket after this extrusion molding, and it solidifies by cooling. And at this time, the mounting rib which protrudes from the outer peripheral surface of a cylindrical body is hard to be cooled with respect to the cylindrical body of a collar. For this reason, there is a possibility that deformation (residual strain) may occur in the heel or residual stress may occur due to the difference in cooling rate between the cylindrical body and the mounting rib.

  The problem to be solved by the present invention is to reduce the amount of elastic deformation of the eaves support and to attach the eaves that allow the tubular body and the attachment ribs to be suitably cooled during manufacture of the eaves. To provide a structure.

  In order to solve the above problems, the present invention provides the following means.

  The flange mounting structure according to claim 1, wherein the flange has a mounting rib projecting outward from an outer peripheral surface of the cylindrical body and extending in an axial direction of the cylindrical body, and an insertion capable of inserting the mounting rib. A scissor mounting structure comprising a scissors support that is formed with a groove, is fixed to an outer wall, and includes a scissor support that fits the mounting rib into the fitting groove to support and fix the scissors, The mounting rib is formed in a hollow shape.

  The scissor mounting structure according to claim 2 is characterized in that, in the scissor mounting structure according to claim 1, the hollow portion of the mounting rib communicates with the inside of the cylindrical body.

  In the mounting structure of the scissors according to claim 1, the mounting rib is formed in a hollow shape and has a hollow portion, so that the mounting rib is supported when the mounting rib is inserted into the insertion groove of the scissors support tool. The mounting rib can be elastically deformed together with the tool. Thereby, compared with the past, the amount of elastic deformation of the heel support can be suppressed, and damage to the heel support can be prevented.

  Further, since the mounting rib is formed with a hollow portion, at the time of manufacturing the ridge, in the process of cooling and solidifying the extruded ridge by water, the mounting rib is formed by circulating water in the hollow portion. Can be cooled. As a result, the cylindrical body and the mounting rib can be cooled at the same cooling rate, and it is possible to reliably avoid the deformation of the heel due to the difference in cooling rate and the occurrence of residual stress. it can.

  In the scissor mounting structure according to claim 2, the hollow portion of the mounting rib and the inside of the cylindrical body are configured to communicate with each other, so that when the mounting rib is inserted into the mounting groove of the scissor support, The mounting rib can be reliably elastically deformed. In addition, the mounting rib can be easily cooled during the manufacture of the bag.

And mounting ribs 2 projecting from the outer peripheral surface 1a of the cylindrical body 1b to the outside in the radial direction of the cylindrical body 1b and extending in the axial direction O1 of the cylindrical body 1b.

  Further, as shown in FIGS. 1 and 3, the mounting rib 2 is provided at the shaft portion 4 that extends radially outward from the outer peripheral surface 1 a of the flange 1, and the projecting direction tip of the shaft portion 4. It has a locking portion 5 formed in a bulging shape so as to protrude from both sides in the direction orthogonal to the axis O1 of the flange 1 and is formed in a substantially T-shaped cross section. Further, as shown in FIG. 3, the mounting rib 2 is formed with a hollow portion 6 on the inner side, and is formed with a thickness substantially equal to the thickness of the flange 1.

  The locking portion 5 is formed such that a rear end surface facing the outer peripheral surface 1a side of the flange 1 is a locking surface 5a, and the locking surface 5a extends in a direction perpendicular to the central axis O2 of the shaft portion 4. Yes. Further, the locking portion 5 has a tip surface 5b formed in a substantially arc surface shape, and in this embodiment, a corner portion where the side surface of the locking portion 5 intersects the tip surface 5b is formed in an arc surface shape. Yes. And when such a mounting rib 2 is manufactured by extrusion molding (or injection molding), the die 1 is integrally formed with the flange 1 by using a mold corresponding to the shape of the mounting rib 2. Yes.

  On the other hand, the heel support 3 is formed by extrusion molding or injection molding using a resin such as AES, ABS, polycarbonate, or polyvinyl chloride. As shown in FIGS. And a pair of locking piece portions 8 each having a locking piece 9 projecting from the both ends of the fixing portion 7 at right angles to the fixing portion 7 and projecting inward from the tip. Has been. Thereby, the heel support 3 is provided with the insertion groove | channel 10 extended in the axial direction O3 (up-down direction) between a pair of latching piece parts 8 of a side part. In addition, a through hole 11 is formed in the fixing portion 7 so as to penetrate from the inner surface to the outer surface of the heel support 3.

  Further, the locking piece 9 has a surface facing the inner surface side of the fixing portion 7 as a locking surface 9a, and this locking surface 9a extends in a direction perpendicular to the axis O3 and is formed along the inner surface of the fixing portion 7. ing. Furthermore, the locking piece 9 is formed with a tapered surface 9b whose outer surface gradually goes to the inner side of the hook support 3 as it goes from the tip of the locking piece 8 toward the fitting groove 10. Further, at this time, as shown in FIG. 3, the locking piece 9 has a length t1 from the locking surface 9 a to the tip of the locking piece portion 8 substantially equal to the length t2 of the shaft portion 4 of the mounting rib 2. Is formed.

  In the scissor attachment structure A of the present embodiment having the above-described configuration, as shown in FIG. 3, when attaching the scissors 1 to an outer wall T such as a house (at the time of construction), first, the scissors support 3 Is attached to the installation surface T1 of the outer wall T. At this time, a screw (stopper) 12 is inserted into the through hole 11 of the fixing portion 7 and the screw 12 is screwed into the outer wall T, so that the heel support 3 attaches the fixing portion 7 to the installation surface T1 of the outer wall T. It is installed in the state where it is in surface contact. Thereby, the eaves support 3 is fixed and installed on the outer wall T with the pair of locking pieces 9 and thus the insertion groove 10 facing outward.

  Next, the flange 1 provided with the mounting rib 2 is disposed at a predetermined position, and the tip surface 5b of the locking portion 5 of the mounting rib 2 presses the tapered surfaces 9b of the pair of locking pieces 9, Push the heel 1 into the heel support 3. When the heel 1 is pushed in in this way, the arcuate tip surface 5b of the locking portion 5 of the mounting rib 2 and the tapered surface 9b of the locking piece 9 of the heel support 3 are guided to each other, and a pair of locking The piece 8 is elastically deformed so as to fall outward, and the insertion groove 10 is expanded. Thereby, the engaging portion 5 of the mounting rib 2 enters the inside of the heel support 3 through the fitting groove 10.

  At this time, in the scissor mounting structure A of the present embodiment, since the locking portion 5 of the mounting rib 2 is formed in a hollow shape, the tip surface 5b is a tapered surface of the pair of locking pieces 9. When pressed by 9b, the pair of locking pieces 8 are elastically deformed, and the locking portions 5 are elastically deformed. Even when the elastic deformation amount of the pair of locking pieces 8 and the expansion amount of the fitting groove 10 are suppressed to be small compared with the conventional case, the locking portion 5 of the mounting rib 2 is elastically deformed, and the fitting groove 10. To the inside of the heel support 3. For this reason, the pair of locking pieces 8 are not greatly elastically deformed and damaged.

  When the locking portion 5 of the mounting rib 2 is thus inserted into the heel support 3, the locking surface 5a of the locking portion 5 and the locking surfaces 9a of the pair of locking pieces 9 come into surface contact. The locking portion 5 of the mounting rib 2 is locked to the pair of locking pieces 9 of the heel support 3. As a result, the hook 1 can be attached simply by pushing the engaging portion 5 of the mounting rib 2 into the hook support 3 from the fitting groove 10.

  In addition, since the mounting rib 2 and the heel support 3 are disposed on the back side of the heel 1 with the heel 1 installed, the locking piece 9 of the heel support 3 further includes the locking surface. Since the length t1 from 9a to the tip of the locking piece 8 is substantially equal to the length t2 of the shaft 4 of the mounting rib 2, the hook mounting structure A is on the back side of the hook 1. There is no loss of appearance by hiding.

  On the other hand, when removing the collar 1, the collar 1 is pulled outward to pull out the locking portion 5 of the mounting rib 2 from the interior of the collar support 3. At this time, the pair of locking pieces 9 of the heel support 3 are pressed by the locking portions 5, the pair of locking pieces 8 are elastically deformed, and the fitting groove 10 is expanded, and together with this, the locking portions 5 Is elastically deformed and pulled out. For this reason, as in the case of attachment, the amount of elastic deformation of the pair of locking pieces 8 and thus the amount of expansion of the fitting groove 10 can be kept small, and the heel 1 can be removed, and the pair of locking pieces 8 are greatly elastically deformed. Will not be damaged.

  Therefore, in the scissor mounting structure A of the present embodiment, the mounting rib 2 is formed in a hollow shape and includes the hollow portion 6, so that the mounting rib 2 is inserted into the fitting groove 10 of the scissor support 3. When fitting, the attachment rib 2 can be elastically deformed together with the heel support 3. Thereby, compared with the past, the elastic deformation amount of the heel support 2 can be suppressed, and it is possible to prevent the heel support 3 from being damaged.

  Moreover, when manufacturing the cage | basket 1 provided with the attachment rib 2 like this embodiment, it shape | molds, for example by extrusion molding, water is poured to the cage | basket 1 after this extrusion molding, and it solidifies by cooling. At this time, in the present embodiment, the mounting rib 2 is formed with the hollow portion 6, so that in the step of cooling and solidifying the extruded trough 1 with water, water is put into the hollow portion 6. Can be circulated to cool the mounting rib 2. Thereby, the cylindrical body 1b and the mounting rib 2 can be cooled at a similar cooling rate, and it is ensured that deformation or residual stress is generated in the flange 1 due to the difference in cooling rate. can do.

  The embodiment of the scissor mounting structure according to the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the present invention. For example, in the present embodiment, the shaft portion 4 of the mounting rib 2 is illustrated in FIG. 3 so as to protrude with a substantially constant width from the base end on the flange 1 side to the tip on the locking portion 5 side. For example, as shown in FIG. 4, the mounting rib 2 may be formed with a shaft portion 4 whose width gradually increases from the substrate toward the tip. Further, as shown in FIG. 4, when the tip surface 5b of the locking portion 5 of the mounting rib 2 is formed in an arc shape having a curvature substantially equal to the curvature of the outer peripheral surface 1a of the flange 1, the mounting rib 2 is provided. However, the appearance of the bag 1 itself can be improved.

  Further, as shown in FIG. 5, the hollow portion 6 of the shaft portion 4 of the mounting rib 2 communicates with the distal end surface 5 b of the locking portion 5, and the shaft portion 4 and the locking portion 5 separated from each other are provided. The mounting rib 2 may be formed to have a substantially T-shaped cross section. Further, with respect to the mounting rib 2 of FIG. 5, the hollow portion 6 of the locking portion 5 is communicated with the hollow portion 6 of the shaft portion 4 that is communicated with the distal end surface 5b of the locking portion 5 as shown in FIG. Thus, the mounting rib 2 may be formed. And when comprised in this way, it becomes easy to elastically deform the separated left-right paired axis | shaft part 4 and the latching | locking part 5. FIG. For this reason, it becomes possible to make attachment and removal of the heel 1 easier than in the present embodiment, and it is possible to suppress deformation of the heel support 3 and damage the heel support 3. Can be prevented more reliably. Moreover, it becomes possible to make it easy to cool the mounting rib 2 at the time of manufacture.
