Description

[Detailed description of the invention] [Field of industrial application] The present invention is a screw fastener for a gutter holder that allows the gutter holder for attaching eaves gutters to the eaves to be easily and quickly attached using bolts and nuts. It is about the mechanism.

[Conventional technology] When attaching gutter brackets to the eaves using screws, bolts, and nuts, conventionally, holes were drilled at the required mounting locations, the brackets were placed in those positions, and bolts were inserted upwards from below. The common method was to support the bolt with one hand to prevent it from falling, and use the other hand to fit and tighten a nut onto the upwardly protruding end of the bolt.

[Problem that the invention aims to solve] However, gutter installation work is often done at high places and is difficult to operate with one hand, so doing it with both hands can be dangerous if the footing is unstable as there is no support. Therefore, there was a problem in that the work could not be done quickly and efficiently.

The present invention was developed in view of the above-mentioned problems with the conventional technology, and its purpose is to place the mounting member of the gutter holder against the underside of the eaves, etc., and insert the bolt into the mounting hole. This is a gutter holder that can be used in high places where the bolt is temporarily held so that it does not fall off when it is inserted upward from the bottom until it is tightened by turning the hand upward and tightening the nut. It is an object of the present invention to provide a screw-fastening mechanism for a gutter holder fitting that allows the installation work to be easily, reliably, and safely carried out.

[Means for Solving the Problems] In order to achieve the above object, the screwing mechanism of the gutter holder in the present invention is such that the mounting member of the gutter holder formed by bending a metal strip is attached to the eaves. In a gutter holder device that is attached to the lower surface of a roof attachment part and fastened with a bolt inserted from below, it is made of a thin sheet metal of a certain narrow width that is attached to the lower part of the neck of the bolt head in a manner to prevent it from coming out. It is a locking plate for temporary fixing of a single plate, and has a series of wing-shaped pieces on both ends of the locking plate that can be freely pressed and bent with fingers so as to sandwich and hold the mounting member from both the left and right sides. It is what it is.

[Example] Fig. 1 shows a gutter holder of a type in which the vertical height can be adjusted steplessly in a sliding manner. , a screw rod 3 protruding from the base 2a is loosely inserted into a long hole 4 of the straight rod portion 1a and fastened with a wing nut 5 from the back side. A mounting hole 6 is opened in the mounting piece 1b on the upper side of the mounting member 1.

The screwing mechanism of the present invention is implemented in such a gutter holder.

As shown in FIGS. 2 to 5, the bolt 7 has a head 7a.
and the screw rod part 7b, and a temporary locking plate 9 made of a thin sheet metal having a certain narrow width is fixed to the lower part 8 of the head of the screw rod part 7b so as not to come off. do. The neck portion 8 is preferably formed with a constricted portion having a smaller diameter than the outer diameter of the thread.

A series of wing-like pieces 9' and 9'' are formed at both ends of the locking plate 9, which can be pressed and bent with fingers so as to sandwich and hold the mounting member 1 from both left and right sides.

2 and 5 show the case where the locking plate 9 is engaged with a square head bolt, and FIGS. 3 and 4 show the case where the locking plate 9 is engaged with a round head screw.

[Operation] Insert the bolt 7 upward from below into the mounting hole 6 provided in the mounting piece 1b of the mounting member 1, and with the locking plate 9 in contact with the lower surface of the mounting piece 1b, use your thumb and forefinger to tighten the wing-shaped ends at both left and right ends. Push and bend the pieces 9' and 9'' to wrap around both edges of the mounting piece 1b and lock them.In this way, the bolt 7 will not fall off even if you release your hand from now on, and it will be temporarily locked on the mounting piece 1b. It becomes what is given.

A bolt 7 is inserted into a roof attachment part 10 such as the eaves, and a nut 11 is screwed into the upper end protrusion and tightened.

[Effects of the invention] As explained above, the present invention provides a locking plate for temporary fixing of a single plate made of thin sheet metal of a certain narrow width to the lower part of the head of the bolt for attaching the mounting member of the gutter holder. It is attached in a manner to prevent it from coming off, and has a series of wing-like pieces 9' and 9'' at both ends of the locking plate, which can be freely pressed and bent with fingers so as to sandwich and hold the mounting member from both the left and right sides. Therefore, when attaching the gutter bracket to the lower surface of the roof attachment such as the eaves and attaching it with a bolt inserted upward from below, insert the bolt into the mounting hole of the mounting member of the gutter bracket and attach it to both ends of the locking plate. The bolt can be temporarily attached to the mounting member by simply pressing and bending the wing-shaped piece with your fingers, and therefore the series of operations from fitting the nut to tightening can be done easily, quickly and reliably. In addition to being able to perform this type of work efficiently, it is also difficult to perform this type of work at high places such as rooftops with poor footing, but since it can be operated with one hand, the other hand supports the entire body and maintains a stable posture. This makes it possible to safely install gutters.

In addition, the locking plate is attached to the mounting member of the gutter holder from both the left and right sides by pressing the wing-shaped pieces at both ends so as to hold both the top and bottom sides, so it functions as an elastic washer after the bolts are tightened. It can be expected to have the effect of preventing screws from loosening, and since it has a simple structure and can be implemented at low cost, it has a great practical effect.
