Description

  The present invention is an eaves hook support tool (hereinafter referred to as a support tool) that supports an eave bar formed by providing a front ear part at the front upper end of the bag main body having a substantially U-shaped cross section and a rear ear part at the rear upper end along the eaves edge. )

As shown in FIG. 6 (A), as a conventional support 61 that can attach the eaves to the eaves with a simple operation, the support arm 61b protrudes from the fixed plate 61a attached to the eaves. The support arm 61b is provided with a recess 61c that engages with the front ear 62a of the eaves 62 at the tip, and can be made thinner than the protrusion 61d protruding toward the fixed plate 61a on the base of the support arm 61b. There is known a configuration in which a tongue piece 61e having flexibility is provided and the rear ear portion 62b of the eave bar 62 is engaged with the upper surface of the tongue piece 61e to support the eave bar 62 (for example, Patent Document 1). reference).
Further, as shown in FIG. 5B, a convex portion 61d is provided on the base portion side of the support arm portion 61a, and a thin tongue 61e is provided on the fixing plate portion 61a opposite to the convex portion 61d. There is known a configuration in which the rear ear portion 62b is engaged with the upper surface of the convex portion 61d to support the eaves rod 62 (see, for example, Patent Document 2).

JP 2002-356964 A JP 2003-41722 A

Among the conventional support devices 61, the former one is such that the rear ear portion 62b of the eaves rod 62 is supported by the upper surface of the tongue piece 61e whose tip is bent downward, Since there is a gap between the rear ear 62b and the fixing plate 61a in a supported state, the contact portion between the rear ear 62b and the tongue piece 61e is reduced when the eaves 62 receives a strong wind. In addition, when the snow masses flow down from the roof into the eave cage 62 and a large downward load is applied to the eave cage 62, the tip of the tongue 621e is further bent, The ear part 62b may fall off from the tongue piece 61e.
In the latter case, the rear ear portion 62b of the eaves rod 62 is stably supported by being engaged with the upper surface of the horizontal convex portion 61d. In addition, when a large downward load is applied to the eaves cage 62 due to the fall of a snow mass, the rear ear 62b is displaced rearward on the convex portion 61d, and the tongue piece 61e is applied to the rear surface of the rear ear 62b. The whole tongue piece 61e is bent downward from its base portion by receiving a pressing force from the rear ear portion 62b and creates a large gap between the convex portion 61d, and the rear ear portion 62b is dropped from this gap. There was a fear of being.

  In view of such a problem of the prior art, the present invention can attach the eaves by a simple operation, and a large external force is applied to the eaves by receiving a strong wind or falling snow blocks. However, it is an object of the present invention to configure the support so that the eaves can be reliably and stably supported without dropping off.

  In order to solve the above-mentioned problems, the present invention provides a front engagement portion in which a support arm portion protrudes from a fixed plate portion attached to an eave tip, and a front ear portion of an eave ridge is engaged with a front end portion side of the support arm portion, a base portion side In the support device having a rear engagement portion with which the rear ear portion of the eaves is engaged, a flexible tongue piece protrudes downward with a support arm portion projecting across the front surface of the fixing plate portion as a base portion. The tongue piece has a configuration in which the rear ear portion and the tongue piece side end portion are arranged to face each other when the rear ear portion of the eaves rod is engaged with the rear engagement portion. To do.

According to this, the attachment of the eaves to the support is performed by manually supporting the eaves under the support fixed to the eaves, first engaging the front ear portion of the eaves with the front engagement portion, and then Rotate the rear side of the eaves ridge upward with the engagement point of the front ear part as a fulcrum, and push up the tip of the tongue piece at the upper end of the rear ear part to engage the rear ear part with the rear engagement part Is done. When the rear side of the eaves is rotated and the upper end of the rear ear comes into contact with the tongue, the tongue receives an upward force from the rear ear, and the tip crawls upward with its base as an axis, Thus, a gap having a width through which the rear ear part can pass is formed between the rear engagement part and the tongue piece, and the rear ear part pushed upward from the gap can be engaged with the rear engagement part. When the rear ear portion is engaged, the tongue piece returns to its original shape by its own elasticity, and the tongue piece is arranged at a position where the side end portion faces the rear ear portion.
When a downward external force is applied to the eaves with the eaves being supported by the support, the rear ear part engaged with the rear engagement part by the downward external force tends to shift the position to the tongue piece side. The side end portion of the tongue piece facing this holds against the rear ear portion to hold the rear ear portion, and prevents the rear ear portion from dropping off from the rear engagement portion. When the rear ear comes into contact with the tongue, a force is applied to the tongue through the rear ear, but the tongue protrudes in a direction intersecting the front surface of the fixed plate, and the force applied from the rear ear is Because it is parallel to the axial direction of the base of the tongue, the tongue does not bend even when force is applied from the rear ear. Prevents falling off from the engaging part.

  In the above-described configuration, the front engagement portion with which the front ear portion of the eaves hook is engaged and the rear engagement portion with which the rear ear portion is engaged are respectively engaged with the respective ear portions according to the shape of the front and rear ear portions of the eaves rod. It can be formed into a concave shape, a convex shape, or a concave-convex shape. Further, the rear engagement portion with which the rear ear portion engages may be provided on the support arm portion side or the fixed plate portion side. In short, the front engagement part is engaged with the front ear part of the eaves hook, and when the eaves hook is mounted on the support, the rear ear is rotated by using the engagement point of the front ear part as a fulcrum. The shape of the back engagement part can be engaged with the rear engagement part, the rear engagement part is engaged with the rear ear part of the eaves and is pushed upward when the eaves is attached to the support. Any shape that can receive the rear ear and engage with it can be used. In addition, the arrangement | positioning dimension between front-and-back engaging parts is set to the magnitude | size which can engage the front-and-rear ear part reliably and stably corresponding to the dimension between the front-and-rear ear parts of the eaves hook to support.

The tongue piece is provided with a flexibility, i.e., it bends moderately by receiving external force, and returns to its original shape by its own elasticity when the external force disappears, and its base part is provided along the lower part of the support arm part, In addition, it is arranged in a direction extending in the direction intersecting the front surface of the fixed plate portion, and the side end portion of the tip protruding downward from the base portion is close to the rear ear portion of the eaves hook engaged with the rear engagement portion. And provided at opposite positions. For example, when the support is integrally formed of plastic resin, flexibility can be provided by forming the tongue piece thinly, and the tongue piece is separated from other parts of the support using an elastic material. It may be formed on the body and attached integrally by post-processing.
When the rear engagement portion is provided at the base portion of the support arm portion facing the fixed plate portion, the tongue piece is provided at a lower portion of the support arm portion between the fixed plate portion and the rear engagement portion. When the joint portion is provided in the fixed plate portion, the joint portion is provided in a lower portion of the support arm portion at a portion facing the rear engagement portion.

  The support can be integrally formed by injection molding or the like using a synthetic resin material such as polycarbonate, vinyl chloride, or polypropylene, or a resin material containing rubber. Each part or part of the support may be formed separately and formed integrally by post-processing.

Preferred embodiments of the present invention will be described with reference to the drawings.

The figure for demonstrating the arrangement position and bending state of a tongue piece seeing from the front, FIG. 4 is the figure which showed the operation procedure which attaches an eaves to the support tool of FIG. 1, FIG. 5 is the support tool of another form. It is a side view of the state which attached the eaves basket. In each of the drawings, reference numeral 1 denotes an eave rod, 2 denotes a support, and 3 denotes an eaves body surface to which the eave rod 1 is attached.

  1 to 4 show an embodiment of a support 2 that supports the eaves rod 1 along the eaves 3. As shown, the eaves 1 supported by the support 2 has a substantially U-shaped cross section. A front ear portion 12 is formed by folding the upper edge of the wall surface of the heel body 11 into a substantially U shape inwardly at the upper front end of the heel body 11 having a letter shape, and the edge is bent inwardly. The upper edge of the wall surface is formed into a cylindrical shape having a substantially triangular cross section, and rear ear portions 13 formed by projecting the cylindrical shape inwardly from the heel are provided to be long.

  The support 2 projects the support arm 22 forward from the front surface of the fixed plate 21 fixed to the eaves 3 with a fixing tool such as a screw, and the front ear portion of the eaves 1 at the tip of the support arm 22. 12, a front engagement portion 23 that engages with the support arm portion 22, and a rear engagement portion 24 that engages with the rear ear portion 13 of the eaves rod 1 are provided below the support arm portion 22. Then, flexible tongue pieces 25 and 25 projecting downward with an appropriate length are integrally formed on both sides of the lower portion of the support arm portion 22 projecting.

  More specifically, the support arm portion 22 protrudes forward with an appropriate length orthogonal to the front surface of the fixed plate portion 21, and the front engagement portion 23 provided on the tip end side is curved upward. After providing the front ear portion 12 so that it can be engaged with and supported by the projecting piece 23a by the warped tip projecting piece 23a and the recessed portion 23b opened upward, The engaging portion 24 projects from the rear ear portion 13 by a projecting piece 24a that branches off from the lower surface near the base portion of the support arm portion 22 and extends toward the fixing plate portion 21 and a recessed portion 24b above the projecting piece. It is provided so that it can be mounted on and engaged with the piece 24a.

Both tongue pieces 25 reach the vicinity of the projecting piece 24a from the front surface of the fixed plate portion 21 in parallel with the support arm portion 22 with the base portion thereof along the lower portion of the support arm portion 22 facing the projecting piece 24a downward. The tip 25a is protruded obliquely downward through a portion 25b that is provided in the width and slightly protrudes laterally from the base. As shown in FIG. 1, the length of both tongue pieces 25 is such that the rear ear portion 13 and the side end portion of the tongue piece 25 are close to each other when the rear ear portion 13 of the eaves rod 1 is engaged with the protruding piece 24a. Thus, the length is set to be opposed to each other, and the tip thereof is inclined downward from the rear engagement portion 24 toward the fixed plate portion 21.
Both tongue pieces 25 are thin and have been given flexibility, and as shown in FIG. 3 (A), they protrude downward on both sides of the lower portion of the support arm portion 22 when no external force is applied. When an upward external force is applied, as shown in FIG. 4B, the tip is largely bent upward with the base side as an axis, and when the upward external force disappears, it returns to its original shape by its own elasticity. It is provided as follows.

The attachment of the eaves 1 to the support 2 of the present embodiment formed in this way is performed by attaching a plurality of supports 2 in advance along the eaves 3 and attaching the eaves 1 between these supports 2 in the following procedure. It is performed by bridging and attaching to each support tool 2.
First, the eaves 1 is supported by the hand below the support 2 fixed to the eaves 3, and the front ear portion 12 of the eaves 1 is placed on the tip of the support arm 22 as shown in FIG. The front engaging portion 23 is engaged.
Next, with the engagement point of the front ear portion 12 as a fulcrum, the rear side of the eaves ridge 1 is rotated upward and lifted upward, and as shown in FIG. Abutting on the tip of the piece 25, it is pushed upward. At this time, the tongue piece 25 is pushed upward at the upper end of the rear ear portion 13 and bent as a whole, so that the rear ear portion 13 can pass between the tongue piece 25 and the projecting piece 24a. A gap is created.
Then, at the position where the rear ear portion 13 that is inserted between the projecting piece 24a and the tongue piece 25 is pushed up beyond the projecting piece 24a, as shown in FIG. 24a, the eaves rod 1 is supported by the support 2 with the front and rear ears 12 and 13 engaged with the front and rear engagement portions 23 and 24, respectively. It is attached. When the rear ear portion 13 is engaged with the protruding piece 24a, the tongue piece 25 that has been swung upward returns to its original shape, and the tongue piece 25 has its side end close to the rear of the rear ear portion 13 to It is arranged at a position facing the ear 13.

  When the eaves 1 attached along the eaves 3 receives a downward external force such as receiving a strong wind, the rear ear 13 mounted on the projecting piece 24a shifts the engagement position backward by the external force. At this time, the side end portion of the tongue piece 25 comes into contact with the rear ear portion 13 to support the rear ear portion 13, and the rear ear portion 13 is held on the protruding piece 24a to prevent dropping. In this case, an external force is also applied to the tongue piece 25 via the rear ear portion 13, but the external force applied from the rear ear portion 13 is in a direction parallel to the axial direction of the base portion of the tongue piece 25, and thus the rear ear portion. The tongue piece 25 does not bend even if it receives a force from 13, and the tongue piece 25 is held at a close position facing the rear ear portion 13, and the rear ear portion 13 can be reliably supported.
