Description

  The present invention relates to an eaves joint for connecting eaves by connecting a pair of eaves from the eaves insertion ports provided at both ends.

  Traditionally, eaves are installed at the eaves of ordinary houses to discharge rainwater, but the installation length is often too long to construct with one eaves over the entire length of the eaves. For this reason, it is common to construct a plurality of eaves of appropriate length by connecting them with eaves joints.

  FIG. 3 is a perspective view schematically showing the structure of an example of a conventional eaves joint. The eaves joint 21 has a shape substantially similar to the outer shape of the eaves to be connected, and connects the front side wall part 22, the rear side wall part 23, the front side wall part 22 and the rear side wall part 23. The bottom wall portion 24, the front side wall portion 22 and the upper edge portion of the rear side wall portion 23 are provided with ear portions 25 and 26 having substantially U-shaped cross sections, and the end portions of the eaves are inserted at both ends. The eaves insertion holes 27 and 28 are provided. The ears 25 and 26 are lower surfaces 25A and 26A extending horizontally from the front and rear side walls 25 and 26, vertical portions 25B and 26B, upper surface portions 25C and 26C, and lower ends of the upper surface portions 25C and 26C, respectively. It is comprised from the bending pieces 25D and 26D which were bent in. Cutouts 29 and 30 are formed in the upper surface portions 25C and 26C in order to make the eaves joint 21 flexible when connecting the eaves to facilitate connection.

In the eaves joint 21 as described above, the eaves are connected by inserting and matching the eaves to be connected from the eaves insertion ports 27 and 28 at both ends. Various types of eaves joint 21 having such a structure have been proposed. For example, Patent Document 1 discloses an example thereof.
Japanese Patent Laid-Open No. 9-228580

  However, in the conventional eaves joint as described above, the upper surface of the ear portion is not completely covered and a notch is provided, or rainwater travels through the eaves ear portion and enters the joint ear portion. In the case of entering, there is a problem that a part of the rainwater flows out like a raindrop from the end face of the joint and may contaminate the building.

  Therefore, the present invention has been made in view of the circumstances as described above, and the upper surface portion of the ear portion is not completely covered and a notch is provided, or rainwater travels in the eaves ear portion. Thus, an object of the present invention is to provide an eaves joint that can prevent a part of rainwater from flowing out from the end face of the joint like raindrops even when entering the joint ear.

  In order to solve the above problems, the eaves joint of the present invention firstly includes a front side wall part, a rear side wall part, a bottom wall part connecting the front side wall part and the rear side wall part, a front side wall part and a rear side part. The cross section provided on the upper edge portion of the side wall portion has a substantially U-shaped ear portion, and has an eaves insertion port for inserting the end of the eaves at both ends, and a pair from the eaves insertion ports at both ends. In the eaves joint for connecting the eaves by matching the eaves, a drainage groove connected to the inner surface of the joint is provided at the inner center of the lower surface of the ear.

  The second aspect of the present invention is characterized in that, in the first invention, the lower surface portion of the ear portion is formed on an inclined surface that is inclined downward from the eaves bowl insertion port side toward the drainage groove.

  According to the first aspect of the present invention, since the drainage groove connected to the inner surface of the eaves ridge is provided at the inner center of the lower surface portion of the ear portion, the upper surface portion of the ear portion is not completely covered and a notch is provided. When rainwater flows through the eaves-ear part and into the joint-ear part, the rainwater drains from the drainage groove to the inner surface of the eaves part. It is possible to prevent the building from becoming dirty due to the scattering of rainwater.

  According to the invention of claim 2 of the present application, since the lower surface portion of the ear portion is formed on the inclined surface that is inclined downward from the eaves jar insertion opening side toward the drainage groove, in addition to the above effect, the drainage from the drainage groove is improved. It can be improved further.

  The present invention has the features as described above, and an embodiment thereof will be described below.

  FIG. 1 is a perspective view schematically showing a structure of an embodiment of an eaves joint according to the present invention, and FIG. 2 is an enlarged perspective view showing a main part of the eaves joint according to the embodiment. The eaves joint 1 of this embodiment has a shape that is substantially the same as the outer shape of the eaves to be connected (not shown), and includes a front side wall 2, a rear side wall 3, a front side wall 2 and A bottom wall portion 4 for connecting the rear side wall portion 3, and ears 5 and 6 having substantially U-shaped cross sections provided at the upper edge portions of the front side wall portion 2 and the rear side wall portion 3 are provided at both ends. It has a structure having eaves ridge insertion ports 7 and 8 for inserting the ends of the ridges. The ears 5 and 6 are lower surfaces 5A and 6A, vertical portions 5B and 6B, upper surface portions 5C and 6C, and upper surface portions 5C and 6C extending horizontally from the front side wall portion 2 and the rear side wall portion 3, respectively. It is comprised from the bending pieces 5D and 6D bent in. Cutouts 9 and 10 are formed in the upper surface portions 5C and 6C in order to make the eaves joint 1 flexible when connecting the eaves to facilitate connection. The above is almost the same as the structure of the conventional eaves joint 21 shown in FIG.

In the eaves joint 1 of this embodiment, in the lower surface portions 5A and 6A of the ear portions 5 and 6 having a substantially U-shaped cross section, the direction in which the lower surface portions 5A and 6A extend (the direction in which the eaves abuts). Drain grooves 11 and 12 (in the central position, in a direction perpendicular to the extending direction of these lower surface portions 5A and 6A, from the lower surface of the vertical portions 5B and 6B to the inner surfaces of the front and rear side wall portions 2 and 3, respectively. The drain grooves 12 are not shown in the drawing). These drain grooves 11 and 12 play a role of draining rainwater that has entered from the notches 9 and 10 and rainwater that has entered the ear portions 5 and 6 through the eaves-ear portion to the inner surface of the eaves-ear portion. The width and depth of the drainage grooves 11 and 12 are such dimensions that the drainage is performed effectively and does not affect the connection of the eaves. In addition, the lower surface portions 5A and 6A of the ear portions 5 and 6 are inclined surfaces 5A ₁ , 5A ₂ , 6A ₁ and 6A ₂ (6A) which are gently inclined from the eaves bowl insertion ports 7 and 8 toward the drainage grooves 11 and 12. _1, 6A ₂ is formed so as to be inclined appear not) in FIG. In the present embodiment, the inclination direction is indicated by a black arrow. The inclined surfaces 5A ₁ , 5A ₂ , 6A ₁ , 6A ₂ are desirably inclined at an angle that does not affect the connection of the eaves and promotes drainage from the drainage grooves 11 and 12. By these inclined surfaces 5A ₁ , 5A ₂ , 6A ₁ , 6A ₂ , rainwater that has entered the ear portions 5, 6 can be drained from the drain grooves 11, 12 to the inner surface of the eaves more effectively.

  The eaves joint 1 of this embodiment can be manufactured by injection molding integrally using, for example, a synthetic resin, but other than the synthetic resin, a resin-coated metal plate, stainless steel, copper, aluminum, or the like is used. It can also be manufactured.

The eaves joint 1 of the present embodiment having the above-described structure is inserted in a form in which a pair of eaves to be connected (not shown) is butted from the eaves insertion ports 7 and 8 provided on both sides thereof. Connect the eaves. In the eaves ridge structure composed of the eaves ridge and the eaves ridge joint 1 connected in this way, rainwater enters the ears 5 and 6 from the notches 9 and 10, and the rainwater is transmitted through the eaves ridges and the ears. Even if it enters the part 5, 6, the rainwater that has entered the drainage grooves 11, 12 is caused by the inclined surfaces 5 A ₁ , 5 A ₂ , 6 A ₁ , 6 A ₂ of the lower surface parts 5 A, 6 A of the ear parts 5, 6. It moves toward and drains from the drainage grooves 11 and 12 to the inner surface of the eaves. Therefore, it does not flow like raindrops from the end face of the eaves joint 1 of this embodiment, and it is possible to prevent the building from being soiled due to the scattering of rainwater.

  While the present invention has been described based on one embodiment, the present invention is of course not limited to the above embodiment, and various modifications and changes can be made.

  For example, in the above embodiment, an example in which the notches 9 and 10 are provided is illustrated, but the present invention can also be applied to the eaves joint 1 without the notches 9 and 10, and the ear is transmitted through the eaves-ear part. Rainwater that has entered the portions 5 and 6 can be drained more effectively than the drainage grooves 11 and 12.

  Moreover, in the said embodiment, although the eaves joint 1 of the structure which connects a square hook as an eaves was shown, this invention is applicable to the connection of various forms of eaves, such as a round eave.

  Further, in the above-described embodiment, a member that does not have a member to be fitted and fixed to the eaves to be connected is shown. However, the present invention includes various forms of members that are fitted and fixed to the eaves to be connected. It is also applicable to.
