Description

  The present invention relates to a relay drain cap mounted on a drainage port of a building.

  The roofs of buildings such as buildings and condominiums and the verandas on each floor are generally provided with drainage outlets that can drain rainwater, and these types of drainage outlets have fallen leaves associated with rainwater. A drain cap is attached from the viewpoints of preventing the intrusion of solid materials such as paper, twigs, paper, vinyl, etc., avoiding the danger caused by the drainage port being exposed, and maintaining aesthetics.

  FIGS. 4 to 6 show an example of a conventional roof drain cap provided on the roof. The roof drain cap has a flange portion 4 for installation on the upper outer side of the drain port 3 of the floor 2 and the flange portion. The roof cap body 1 includes an upper protrusion 5 that protrudes upward from 4 and closes the drain port 3 so as to allow water to pass therethrough. The upper end of the roof cap body 1 has an upper protrusion 5 inside the cap body 1. A rod member 6 fixed to the inner center position of the rod member 6 and extending downward to a required length is fixed. The lower end portion of the rod member 6 is intermediate between two elongated spring plates 7 crossed in a cross shape. The part (intersection) is screwed. In addition, 8 in FIG. 4 has shown the water intake for introducing the rain water formed in the cap main body 1 for rooftops.

  On the other hand, the drain main body 10 is embedded together at the position of the drain port 3 of the floor 2 when the fluid hardened material 9 such as mortar, cement, resin or the like for forming the floor 2 is placed. When the both ends of 7 are bent downward and inserted into the drain port 3, each of the spring plates 7 is pressed against the inner peripheral surface of the drain body 10 by elastic force, so that the cap body 1 for rooftop is drained. 3 is fixed.

  On the other hand, a veranda on each floor below the roof is provided with a relay drain cap as shown in FIG. 7, for example.

  The relay drain cap includes a flange portion 4 for installation on the upper outer side of the drain port 3 of the floor 2, and an upper projection 5 that protrudes upward from the flange portion 4 and closes the drain port 3 so as to allow water to pass therethrough. A relay cap body 11 is provided. At the center of the upper protrusion 5 of the relay cap body 11, there is a waterfall pipe 12 that is connected to the drain body 10 of FIG. 6 and extends downward to drop the water collected by the rooftop cap body 1. An opening 13 to be inserted is formed. Thus, since the lower end of the water pipe 12 is inserted into the opening 13 of the relay cap body 11, the rod material 6 as shown in FIGS. 4 to 6 can be provided at the center of the relay cap body 11. Can not.

  For this reason, the relay cap main body 11 is provided with a projecting plate 14 projecting inwardly in the lower flange portion 4, and one end of the spring plate 15 is screwed in, for example, three locations in the circumferential direction of the projecting plate 14. It is fixed by 15a. Each spring plate 15 is bent so as to be directed downward and outward after being directed toward the center of the relay cap body 11 from the fixing portion by the screw 15a. It is also conceivable that the overhanging plate 14 and the spring plate 15 are integrally formed without making the overhanging plate 14 and the spring plate 15 separate. In FIG. 7, 8 is a water intake for introducing rainwater formed in the relay cap body 11, and 16 is a water drop hole formed in the overhanging plate.

  When the lower end of each spring plate 15 is bent toward the center of the relay cap body 11 and inserted into the drain port 3, each spring plate 15 is elastically applied to the inner peripheral surface of the drain body 10. The relay cap body 11 is fixed to the drain port 3 by pressure contact.

As prior art document information related to the above-described roof drain cap, there is the following Patent Document 1 by the same applicant as the present invention.
Japanese Patent No. 3050785

  In the conventional relay drain cap shown in FIG. 7, the overhanging plate 14 that protrudes from the lower inner side of the relay cap main body 11 is provided, and the spring plate 15 is fixed to the overhanging plate 14. In addition, there is a problem in that the fixing of the spring plate 15 is cantilevered at one point and sufficient fixing strength cannot be obtained or the fixing strength tends to vary. Further, since the spring plate 15 is bent from the fixed portion to the center of the relay cap body 11 and then bent downward and outward, the spring plate 15 is difficult to bend. Therefore, there is a problem that the bending shape is likely to vary, and the shape of each spring plate 15 needs to be adjusted in the field.

  Further, since the overhanging plate 14 protruding in the inner circumferential direction is provided at the lower part of the relay cap main body 11, there is a problem that dust or the like easily accumulates on the overhanging plate 14.

  Furthermore, as described above, the bent spring plate 15 has a longer length between the fixing point of the screw 15a and the tip contacting the inner surface of the drain port 3, and the spring strength is reduced. Has a problem that the fixing strength of the relay cap main body 11 by the spring plate 15 is lowered because it contacts the inner surface of the drainage port 3 at a point.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a relay drain cap that can easily and reliably fix the relay cap body to the drain outlet with a simple configuration.

  The present invention is a relay drain cap provided with an opening through which a waterfall pipe is inserted at the center of the upper projection of the relay cap main body that covers the drain outlet of the floor so as to allow water to flow therethrough.

  In the relay drain cap, the fixing member may include a downwardly extending portion that extends downward.

  In the relay drain cap, the spring plate can fix the center position of the length extending in the diameter direction of the relay cap body to the lower surface of the fixing member.

  Thus, in the relay drain cap, when the spring plate fixed to the fixing member is bent toward the center of the relay cap body and inserted into the drain port, the tip of the spring plate is in surface contact with the drain port. It comes in pressure contact with the inner peripheral surface.

  At this time, since the spring plate is fixed to the fixing member provided at the center position of the relay cap body, a linear spring plate can be used, and even if the length of the spring plate is shortened, the spring plate can be used. Therefore, the fixing strength of the relay cap body fixed to the drainage port by the spring plate can be increased. Furthermore, since the spring strength of the plurality of spring plates extending in the radial direction can be kept uniform, the relay cap body can be stably fixed to the drain outlet.

  Further, by integrally forming the fixing member and the supporting member, the number of parts can be reduced and the assembling work can be facilitated.

  Further, by providing a spring plate detent means at the lower end of the fixing member, the spring plate is prevented from shifting in the circumferential direction of the relay cap body, and the mutual spacing of the spring plates is properly maintained. become.

  Further, since the fixing member has a downward extending portion extending downward, the fixing position of the spring plate can be set to a position where the spring plate is deeply penetrated into the drain outlet, and thus the curved surface is formed in the upper opening of the drain outlet. The relay cap body can be stably fixed even in the presence of.

  Also, the spring plate is fixed at the center of the length of the relay cap body in the diametrical direction to the lower surface of the fixing member. The number of points can be increased, and furthermore, the fixing strength is stabilized in order to fix the center position of the length of the spring plate, and the contact strengths of the contact points at both ends can be kept even.

  According to the relay drain cap of the present invention described above, since the spring plate is fixed to the fixing member provided at the center position of the relay cap main body, the length of the spring plate is shortened by using a linear spring plate. Even in this case, the front end of the spring plate can be brought into surface contact with the drain port, and therefore, there is an effect that the fixing strength of the relay cap body to the drain port by the spring plate can be increased. Furthermore, the spring strength of the plurality of spring plates extending in the radial direction can be kept uniform, so that the relay cap body can be stably fixed to the drain outlet. Further, the spring plate can be easily fixed to the fixing member, and the labor required for attaching the spring plate can be remarkably reduced. Further, since the structure is simple and the spring plate can be easily attached, the production cost of the relay drain cap can be greatly reduced.

  Further, since the fixing member and the support member are integrally formed, the number of parts is reduced, and the assembling work is further facilitated.

  In addition, since the lower end of the fixing member is provided with a spring plate detent means, the spring plate is prevented from shifting in the circumferential direction of the relay cap body, and the mutual spacing between the spring plates is properly maintained. is there.

  Moreover, since the fixing member has a downward extending portion extending downward, the fixing position of the spring plate can be set to a position where the spring plate is deeply penetrated into the drain outlet, so that a curved surface exists in the upper opening of the drain outlet. In this case, the relay cap body can be stably fixed.

  Also, the spring plate is fixed at the center of the length of the relay cap body in the diametrical direction to the lower surface of the fixing member. It is possible to increase the number of points, and to fix the center position of the length of the spring plate, there is an effect that the fixing strength is stabilized and the contact strengths of the contact points at both ends can be uniformly maintained.
