Description

  The present invention relates to a mounting structure for a cap attached to the end of a gate pillar, fence post, etc. (hereinafter, typically referred to as a gate pillar) made of a hollow shape material. The present invention relates to a mounting structure for a cap that is inserted and fixed by screwing a screw from the outside of the gate pillar.

  A cap is attached to the upper end of the gate pillar for the purpose of improving aesthetics, preventing corrosion and preventing injury. In general, a cap is integrally formed with a cover portion that covers the upper end surface of the gate pillar and an insertion portion that is inserted into the end portion of the hollow portion of the gate pillar, and is usually made of resin, but is made of metal such as aluminum. There is also.

  When the cap is made of metal, the strength is high, so even if one screw is screwed into the insertion part inserted into the gate column from the outside of the gate column (even if one is stopped), the cap is firmly fixed. When the cap is made of resin, the strength of the cap is weaker than that of metal, so if one is stopped, the cap is pulled to one side where the screw is screwed. Since the other side floated, it was not stable unless a plurality of screws were used on the opposite sides (Patent Document 1).

  In addition, the fitting part and the fitted part are formed on the inner wall surface of the gate pillar and the outer surface of the insertion part of the cap, respectively, and the fitting part and the fitted part are not inserted into the gate pillar. A cap mounting structure configured to be fitted and locked to each other is also known (Patent Document 2).

JP 2002-309876 A Paragraph 0003, FIG. Japanese Patent Laid-Open No. 8-291676, paragraphs 0009-0011, FIG.

  As described above, conventionally, in order to attach the cap with stability, at least two screws are screwed in from opposite sides and fixed, so a screw through hole is provided on the opposite sides of the upper end of the gate post, Since it is necessary to provide screw holes for screwing screws on the opposite sides of the cap insertion part, processing costs are required, and work for screwing at least two screws on opposite sides is required, which requires labor. In addition, there was a problem that parts cost and construction cost were required.

  In addition, the mounting structure that engages and locks by forming a fitting part and a fitted part on the inner wall surface of the gate pillar and the outer surface of the insertion part of the cap, respectively, has complicated gate pillar and cap shapes, and is easy to manufacture Therefore, there is a problem that the manufacturing cost increases.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to attach a cap that is inserted by inserting a cap insertion portion into an end of a hollow portion of a gate pillar and screwed in and fixed from the outside of the gate pillar. The structure is designed to prevent the cap from being lifted even if it is stopped with a single screw. At the same time, a cap mounting structure that can reduce the processing cost, simplify the work, and reduce the construction cost is provided. The purpose is to do.

In order to achieve the above object, the present invention is characterized in that a portion into which the screw of the insertion portion of the cap is screwed is formed so as to be deformable outward by a pull-in force at the time of screw screwing.
With the above configuration, when the screw is screwed, only the portion of the cap insertion portion into which the screw is screwed is deformed and pulled toward the gate pole side, so that even if one screw is used, the cap does not rise.

In the present invention, in order to form a portion into which the screw of the insertion portion of the cap is screwed so as to be deformable outward by a pulling force at the time of screwing, the portion into which the screw of the insertion portion of the cap is screwed is separated from the insertion portion. It is formed in a tongue piece, a screw hole is provided in the center of the tongue piece, and screw receiving pieces are formed on both sides of the screw hole with an interval equal to the diameter of the screw hole (claim 2).
With the above configuration, the pulling force when the screw is screwed is transmitted only to the tongue piece, and the tongue piece is elastically deformed outward, so that the cap is not pulled toward the screw screwing side. Therefore, the cap does not lift even with one screw. Further, since the screwed screw is screwed between the screw receiving pieces, the coupling force between the screw and the cap is increased, and the tongue piece is prevented from being damaged.

Further, in the present invention, since the part into which the screw of the cap insertion part is screwed is formed to be deformable outward by the pulling force at the time of screwing, the part into which the screw of the cap insertion part is screwed is formed thinly. A screw hole is formed in a portion into which the screw is screwed, and screw receiving pieces are formed on both sides of the screw hole with an interval equal to the diameter of the screw hole.
With the above configuration, the thin portion of the insertion portion of the cap is elastically deformed outward by the pulling force when the screw is screwed in, so that the cap is not pulled toward the screw screwing side. Therefore, the cap does not float up. Since the screwed screw is screwed between the screw receiving pieces, the coupling force between the screw and the cap is increased, and the tongue piece is prevented from being damaged.

Further, the present invention is characterized in that the cap is made of a metal such as aluminum, the portion into which the screw of the insertion portion is screwed is formed thin, and the screw hole is formed in the portion into which the screw is screwed (claim). Item 4).
According to the above configuration, the portion into which the screw of the thin portion of the insertion portion of the cap is screwed is plastically deformed outward by the pulling force when the screw is screwed in, so that the cap is not pulled toward the screw screwing side. Therefore, the cap does not float up.

  According to the first aspect of the present invention, the portion into which the screw of the insertion portion of the cap is screwed is deformed by the pulling force at the time of screw screwing, so that the cap is not pulled toward the screw screwing side. Accordingly, it is possible to provide a mounting structure in which even one screw does not lift the cap. In addition, the processing cost can be reduced, the labor can be simplified, and the construction cost can be reduced.

  According to the invention of claim 2, since the tongue piece is elastically deformed outward by the pulling force when the screw is screwed, the cap is not pulled toward the screw screwing side. Accordingly, it is possible to provide a mounting structure in which even one screw does not lift the cap. In addition, since the screwed screw is screwed between the screw receiving pieces, the coupling force between the screw and the cap is reinforced, so the thickness of the insertion part is thin, so the screw fixing force is reduced due to breakage of the screw hole. There is no invalidation.

  According to the invention of claim 3, since the thin portion of the insertion portion of the cap is elastically deformed outward by the pulling force when the screw is screwed, the cap is not pulled toward the screw screwing side. Therefore, the cap does not lift even with one screw. Further, since the screwed screw is screwed between the screw receiving pieces, the coupling force between the screw and the cap is reinforced.

  According to the fourth aspect of the present invention, the portion into which the screw of the thin portion of the insertion portion of the cap is screwed is plastically deformed by the pulling force when the screw is screwed in, so that the cap is not pulled toward the screw screwing side. Therefore, the cap does not lift even with one screw.

It is sectional drawing which shows a preferable example of embodiment of this invention. It is a front view of the cap concerning the present invention. It is a top view of the cap. It is a bottom view of the cap. It is a side view of the cap. It is the sectional view on the AA line of FIG. It is a figure which shows the change before and after screw screwing of the tongue piece of a cap.

Next, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a gate pillar made of a hollow material having a square cross section, which is located at a center position in the width direction of the side wall 11 a predetermined distance from the upper end of the gate pillar to one of the four side walls 11. A hole 12 is provided for penetrating the cap mounting screw 3.
In FIG. 1, reference numeral 2 denotes a resin cap, which is a shallow regular quadrangular pyramid-shaped lid portion 21 and a shallow regular square tube that hangs down from the lower surface at a position that is a predetermined equal distance from the periphery of the lid portion. It has the shape insertion part 22 integrally. In the periphery of the lid portion 21, a fitting edge 23 that is continuous along a regular square that hangs down by a small distance is formed, and a groove 24 that opens downward is formed between the fitting edge 23 and the insertion portion 22. Is formed. The width of the groove 24 is set to be slightly larger than the thickness of the side wall 11 of the gate pillar 1.

  A plurality of thin vertical ribs 25 are provided at appropriate intervals on the outer surface of each side of the insertion portion 22 of the cap 2. The protruding height of the rib 25 is substantially equal to the difference between the width of the groove 24 and the thickness of the side wall 11 of the gate pillar 1. As a result, the insertion portion 22 of the cap 2 can be tightly fitted to the hollow portion 13 from the upper end portion of the gate column 1 with little frictional resistance, and the upper end edge of the gate column 1 is tightly fitted to the groove 24 when the fitting is finished. Can be inserted. The cap lid portion 21 covers the upper end surface of the gate column 1 and seals the hollow portion 13.

  At least one side of the insertion portion 22 of the cap 2, in the example shown in the figure, extends from the lower side of the insertion portion 22 to the vicinity of the upper side at two opposite sides to each other at an equal distance from the width center of the side. A thin slit 26 is provided, and a tongue piece 22a is formed between the slits so as to be cut off from the insertion portion 22 continuous in a rectangular shape. Since the tongue piece 22 a is separated from the insertion portion 22, it is more easily elastically deformed in a direction perpendicular to the plate thickness than other portions of the insertion portion 22. And the screw hole 27 is provided in the center of each tongue piece 22a. Further, on the back surface of the tongue piece 22 a, vertical rectangular screw receiving pieces 28 are provided on both sides of the screw hole 27 with an interval substantially equal to the diameter of the screw hole 27.

  In order to attach the cap 2 having the above configuration to the gate pillar 1, the insertion surface 22 of the insertion portion 22 of the cap 2 is inserted in parallel with the side wall 11 a where the hole 12 of the gate pillar 1 is provided. The portion 22 is inserted into the hollow portion 13 of the gate column 1 until the upper end portion of the side wall of the gate column is fitted into the groove 24 around the cap lid portion. Subsequently, the screw 3 is screwed from the hole 12. FIG. 7A shows the positional relationship between the tongue piece 22a of the insertion portion and the side wall 11a of the gate pillar 1 before screwing. The screw is screwed into the screw hole 27 of the tongue piece 22a of the cap and is screwed between the screw receiving pieces 28 on both sides. Since the insertion portion 22 of the normal cap is formed to be relatively thin, the coupling force to the insertion portion of the screw 3 is not so large. Therefore, the required coupling strength can be obtained by screwing the screw to the opposite sides of the insertion portion. It has gained. In the embodiment of the present invention, when the insertion portion 22 is formed thin like a normal cap, screw receiving pieces 28 are provided on the back surface of the tongue piece 22a at intervals equal to the diameter of the screw hole 27. Since the screwing distance of the screw is increased, a sufficient bonding strength can be obtained between the screw 3 and the cap 2 even if only one screw is fixed.

  When the screw 3 is screwed into the tongue piece 22a, the screw 3 applies a pulling force to the tongue piece 22a, but the tongue piece 22a is separated from other portions of the insertion portion by the slits 26 on both sides thereof, and is elastically deformed. Therefore, only the tongue piece 22a into which the screw 3 is screwed is pulled toward the side wall 11a side of the gate pillar 1. FIG.7 (b) shows the positional relationship of the side wall 11a of the gate pillar after screw screwing, and the tongue piece 22a. Accordingly, the tight fitting state of the cap 2 to the gate pillar 1 does not deteriorate, so that the side opposite to the screw 3 of the cap does not float.

  In the illustrated example, in order to separate the tongue piece 22a from the insertion portion 22 that is continuous in a rectangular shape, thin slits 26 are provided on both sides of the tongue piece 22a. However, instead of the slit 26, a relatively wide slot or notch is provided. May be. That is, the insertion portion 22 may have a shape that is not continuous in a rectangular tube shape as long as the fitting state with respect to the gate pillar is good. Moreover, the cross-sectional shape of the gate pillar 1 is arbitrary, such as a regular polygon, a non-regular polygon, and a circle (a perfect circle, an oval, and an ellipse), and the cap is attached to the cap or the insertion portion. It can be set to an arbitrary shape corresponding to the shape of the gate pillar.

  In order to make the portion into which the screw 3 of the insertion portion 22 of the cap 2 is screwed into deformable by the pulling force of the screw 3, it corresponds to the tongue piece 22a of the insertion portion continuous in a square without providing the slit 26 or the slot. This can also be achieved by molding the part to be made of a material that is softer than the relatively hard material of the other part. In this case, only the portion into which the screw is screwed is elastically deformed by the pulling force of the screw to be screwed in, so that the cap 2 is not pulled toward the screw side. Therefore, the cap does not float up.

  Further, when an aluminum cap is used, the same object can be achieved by forming the tongue piece 22a between the slits 26 so as to be plastically deformable by the pulling force of the screw. When the tongue piece is formed to be thin, it is effective to provide screw receiving pieces with a space equal to the diameter of the screw hole on both sides of the screw hole on the back surface of the tongue piece as in the example shown in the figure. Is as described above.

  The cap mounting structure according to the present invention is not limited to the above-described gate pole and fence post caps, but can also be applied to handrail lattices, surface lattices, louver blades, and the like.
