Description

Eaves support

  The present invention relates to an improvement of an eaves bar support provided with a front ear locking part and a rear ear locking part for locking the front and rear ears of the eaves basket.

  Conventionally, in an eaves heel support provided with a front ear locking portion and a rear ear locking portion for locking the front ear and the rear ear of the eaves rod, the front ear and the rear ear are connected to the corresponding front ear locking portion and Various methods have been proposed for preventing the front and rear ears from coming off after being fitted into the rear ear locking portions (see, for example, Patent Document 1).

  3 (a) and 3 (b) show a conventional eaves support that shows an example of a structure that prevents the front and back ears from coming off, and FIG. FIG. 3B is a schematic explanatory view showing a structure for preventing the detachment of the front and back ears using pins that can be raised and lowered.

  In the eaves hook support tool 100 shown in FIG. 3A, the front ear locking portion 101 and the rear ear locking portion 102 are provided with a dropout that prevents the front ear T1 and the rear ear T2 of the eaves hook T from coming off. The stop spring piece 103 is protruded inward.

  In the eaves hook support device 100 having such a configuration, the front ear T1 and the rear ear T2 of the eaves hook T are directed toward the retaining spring pieces 103 from below the front ear locking portion 101 and the rear ear locking portion 102, respectively. When pushed, this retaining spring piece 103 is elastically deformed upward as indicated by an arrow in the figure, and the front ear T1 and the rear ear T2 are inserted into the front ear locking portion 101 and the rear ear locking portion 102. Then, the front ear T1 and the rear ear T2 are locked.

  On the other hand, at the same time as the front ear T1 and the rear ear T2 are locked, the retaining spring piece 103 that has been elastically deformed upward is restored to the original position shown in the figure by its elastic force. It is possible to prevent the T1 and the rear ear T2 from coming off.

  Next, the eaves hook support tool 200 shown in FIG. 3B prevents the front ear T1 and the rear ear T2 of the eaves hook T from coming off in the front ear locking portion 101 and the rear ear locking portion 102. A vertically movable pin 104 is provided.

  In the eaves hook support tool 200 having such a configuration, when the front ear T1 and the rear ear T2 of the eaves hook T are pushed toward the respective pins 104 from below the front ear locking portion 101 and the rear ear locking portion 102. As shown by the arrows in the figure, the pin 104 is pushed upward to insert the front ear T1 and the rear ear T2 into the front ear locking portion 101 and the rear ear locking portion 102, and these front ear T1. And the rear ear T2 is locked.

  On the other hand, the front ear T1 and the rear ear T2 are locked, and at the same time, each pin 104 pushed upward is dropped and restored to its original position by its own weight. It is possible to prevent the T1 and the rear ear T2 from coming off.

  However, there are various types of eaves T, for example, if the eaves T ′ made of metal having high strength, as shown in FIGS. 4 and 5, the front ear T1 and the rear ear T2 are formed. For this reason, the ends formed by bending them are terminated inward. Therefore, in such eaves T 'made of metal or the like, a lateral groove T3 is formed in the upper part of the inner wall surface.

  4 (a) and 4 (b) are schematic explanatory views showing a state in which the eaves cage T 'is attached to the eaves cage support 100 shown in FIG. 3, and FIGS. 5 (a) and 5 (b) The schematic explanatory drawing of the state which attached the eaves T 'to the eaves eaves support 200 shown in FIG. 3 is each shown.

  First, as shown in FIG. 4A, if the eaves ridge T ′ is attached to the eaves ridge support 100 in the manner described above, the retaining spring piece 103 is removed if the eave ridge T ′ moves slightly due to wind and rain. Is fitted into the lateral groove T3, and as shown in FIG. 4 (b), there is a risk that the eaves bowl T 'is tilted and locked, or the eaves bowl T' falls off.

On the other hand, as shown in FIG. 5A, if the eaves ridge T ′ is attached to the eave ridge support 200 in the above-described manner, each pin 104 can be moved even if the eave ridge T ′ moves slightly due to wind and rain. Regulates the lateral movement of the front ear T1 and the rear ear T2, and as shown in FIG. 5 (b), the eaves trap T 'is tilted and locked, or the eaves trap T' falls off. There is no.
JP 2001-182242 A

  The eaves rod support 200 provided with the pins 104 that can be moved up and down in this way has a problem that the processing accuracy of the pins 104 is required, but is related to the shape of the eaves rods T and T ′, that is, the presence or absence of the lateral groove T3. In addition, it is preferable in that the front ear T1 and the rear ear T2 can be prevented from coming off.

  However, the eaves hook support 200 is configured so that when the front ear T1 and the rear ear T2 of the eaves T, T ′ are inserted into the front ear locking portion 101 and the rear ear locking portion 102 and locked, Since the pin 104 is structured to fall, there is a problem that it is difficult to confirm that the eaves hooks T and T ′ are inserted into the front ear locking portion 101 and the rear ear locking portion 102 and locked.

  In particular, in the work of attaching the eaves T and T 'to the eaves support 200, the eaves T and T' are often mounted with the eaves T and T 'looking up from below, and visual confirmation is often impossible.

  On the other hand, in the eaves hook support 100 provided with the retaining spring piece 103, the front ear T1 and the rear ear T2 of the eaves T, T ′ are inserted into the front ear locking part 101 and the rear ear locking part 102. When locked, a click sound is generated when the retaining spring piece 103 is elastically restored, so that the eaves hooks T and T ′ are inserted into the front ear locking portion 101 and the rear ear locking portion 102 and locked. However, as described above, there is a risk that the eaves bowl T ′ is tilted and locked, or the eaves bowl T ′ falls off.

  For this reason, the shape of the end of the retaining spring piece 103 in the eaves support 100 is modified so that it does not fit into the lateral groove T3 to form a retaining spring piece 103 dedicated to the eaves T ′. However, since the eaves T ′ formed with the transverse groove T3 is less produced than the general eaves T, if the retaining spring piece 103 dedicated to such eaves T ′ is formed, Therefore, there is a problem that material costs, processing costs, etc. are newly required, resulting in high costs.

  The present invention aims to solve such a problem, and prevents the front ear T1 and the rear ear T2 from coming off regardless of the shape of the eaves T, T ′, that is, the presence or absence of the transverse groove T3. In addition, an inexpensive eaves support that can easily confirm that the eaves hooks T and T ′ are locked to the front ear locking portion 101 and the rear ear locking portion 102 is provided.

To achieve the above objective,
The eaves hook support device according to the present invention is the eaves hook support device provided with the front ear locking portion and the rear ear locking portion for locking the front ear and the rear ear of the eaves rod. The ear locking portion is provided with a retaining spring piece that protrudes inward to prevent the front and rear ears from coming off, and the front and rear ear locking portions can be raised and lowered freely. In addition, the shaft hole through which the pin communicates is formed as a loose hole having an outer diameter of the pin × 1.04 to 1.07 .

According to the present invention , the front ear and the rear ear can be prevented from coming off regardless of the presence or absence of the lateral groove formed on the inner wall surface of the eaves bowl, and the eaves bowl can be attached to the front ear locking section and the rear ear locking section. It is possible to easily confirm that it is locked and to manufacture an inexpensive eaves support.
Moreover, by forming the shaft hole through which the pin passes into a loose hole of the outer diameter of the pin × 1.04 to 1.07, the pin can be lifted smoothly and smoothly without being caught in the shaft hole.

  Hereinafter, the eaves support A according to the present invention will be described with reference to the drawings.
