Description

[Detailed explanation of the invention] (Industrial application field) This invention is a novel method that can be attached to the lower end of a door, etc., and temporarily lock and secure the door, etc. using a hole provided in the floor etc. This relates to a type of locking metal fitting.

(Prior Art) Conventionally, as shown in FIG. 3, a locking metal fitting is made by pressing a rectangular plate-like member to provide a tubular protrusion 21 in the center in the longitudinal direction, and a retaining plate 22 pressed from the back side. A metal fitting main body 24 including a holding part 23 fixedly formed by welding, and a round rod-shaped locking rod 2 rotatably and slidably fitted into the holding part 23.
It consists of 5. Incidentally, reference numeral 26 indicates a fixing leg 27 in a hole having a screw drilled at a predetermined location of the locking rod 25.
A knob 28 is provided by screwing together the holding part 2.
A communication hole 29 is drilled at a required location on the upper part of the holding part 23 through which the fixed leg 27 can pass when the locking rod 25 is lowered. The length of the protrusion 30 of the locking rod 25 that has been cut is adjusted as appropriate, and the locking rod 2
a locking portion 31 that stops the movement of the knob 26 and prevents the knob 26 from protruding to the front and getting in the way;
32 is a screw hole used for attaching the metal fitting body 24 to a door, etc., and 32 is a stepped portion formed by bending the left and right ends of both pedestals 33 into an L shape in order to improve the stability of the metal fitting body 24. .

This locking metal fitting 34 is attached to the metal fitting main body 2 with the holding part 23 without the communication port 28 on the lower side by screwing it through the screw hole 31 at an appropriate location below the door, especially the movable door.
4 and move the movable door to a predetermined location, raise the knob 26 to the position of the communication port 28, lower the locking rod 25, and insert the protrusion 30 into the hole provided in the floor. from the locking part 29 at an appropriate position.
This is used to temporarily fix the movable door by lowering the knob 26. When it is no longer necessary to fix, raise the knob 26, move the communication port 28, pull up the locking rod 25, store the protruding part 30 inside the holding part 25, and then move the knob 26 to the uppermost locking part. 29 to unlock the movable door.

(Problems to be Solved by the Invention) The metal fitting main body 24 of the above-mentioned locking metal fitting 34 is formed by pressing a rectangular plate-like member to form a tubular protrusion 21 at the center in the longitudinal direction, and further press-forming a holding plate. Since it is made by welding 22 together from the back side,
The drawback is that the welding work is difficult and requires a lot of man-hours, making it expensive.

Furthermore, although the knob 26 is screwed onto the locking rod 25 via a fixed leg 27, there is a drawback that the screw may loosen and fall off during use. To prevent this from falling off, adhesive is used when screwing in, but it still sometimes falls off. Instead of simply screwing in, it would be better to caulk the bottom after screwing in or press-fitting, but it is structurally impossible to caulk.

Furthermore, since the knob 26 has a structure that allows it to be easily raised, something may touch the knob 26 and cause it to be raised without your knowledge, causing the locking rod 25 to descend and protrude from the bottom. There is also the drawback that accidents can occur, such as moving the floor and damaging the floor.

In addition, the metal fitting body 24 is plated with chrome to avoid corrosion, but it is recommended to plate the parts with many protrusions or corners such as the communication port 28, the locking part 29, and the screw hole 31 on average. It is extremely difficult, and has drawbacks such as localized rust and high plating costs.

In addition, the cut edges on the surface of the communication port 28 and the corner portions of the locking portion 29 should be rounded as much as possible so that the knob 26
Although precautions have been taken to prevent injury to fingers and hands when operating the machine, it is still not possible to completely prevent injury accidents from occurring.

(Means for Solving the Problems) The present invention has been developed by focusing on the above-mentioned problems in the conventional art.The main body of the fitting is integrally formed by press working, and the fixed leg of the knob is The aim is to solve the above problem by creating a structure that allows secure crimping of the stopper and by providing a protective cover on the knob.

The present invention presses a metal fitting member in which a plurality of inverted mountain-shaped cut portions are bored at a required gap near the top of the center in the longitudinal direction, and horizontal U-shaped cut portions are formed near the cut portions at both ends. machined; a tubular protrusion formed at the center in the longitudinal direction, including a communication port that communicates with the center portion of the cutting portion; and a locking portion having a recess connected to the communication port; A metal fitting body consisting of a pedestal formed by folding at right angles on both sides of the part, and a protrusion formed perpendicularly within the tubular protrusion by overlapping both ends; and a holding part consisting of the tubular protrusion and the protrusion. The fixing leg of the knob with the cover fixed thereto is inserted into the through-hole drilled in the upper part in a rotatable and slidable manner, and the cover is fixed by caulking through the caulking hole formed in the notch. This locking metal fitting is characterized by being composed of a locking rod that is shaped like a locking rod.

(Function) The main body of the locking metal fitting is mainly made by press working, making it possible to eliminate the need for the conventional retaining plate and welding work.Furthermore, it is possible to stack both pedestals on top of each other and prevent the inside of the tubular protrusion. Mechanical strength can be significantly increased by protruding the protrusions.

In addition, the bottom of the knob can be caulked by inserting the fixing leg into the through hole of the locking rod and using the caulking hole provided on the back of the metal fitting body, so the fixing leg can be held securely and the cover can be secured easily. Equipped with this feature, there will be no damage caused by operating the knobs.

Furthermore, when the knob is pushed down to the locking portion, the fixed leg enters the recess, so even if something touches the knob, it will not wake up, so there is no chance of damage like in the conventional case.

(Example) The present invention will be described in detail below based on an example shown in the drawings. 1 has three inverted mountain-shaped cutting parts 2 placed at a required interval near the upper part of the center in the longitudinal direction.
and horizontal U near the cutting part 2 at both ends in the longitudinal direction.
A metal fitting member 4 having a notch 3 in the shape of a letter is pressed, and a tubular projection 5 is formed in the center, and both sides of the tubular projection 5 are formed with a predetermined width at right angles to the tubular projection 5. On a plane that passes through the axes of the folded pedestals 6, 6 and the tubular protrusion 5 and is perpendicular to the surfaces of the pedestals 6, 6, both ends are overlapped and cut vertically at a predetermined height. The tubular protrusion 5 is provided with a protrusion 8 which together constitute the holding part 7.
A communication port 9 is formed by cutting the central part of the three cutting parts 2 located in the upper part of the board, and the three cutting parts 2 communicate with the communication port 9 through the bored parts 2' on both the left and right sides. It is provided with a locking part 10 formed in the same manner as shown in FIG.

Reference numeral 12 denotes a locking rod in the shape of a round bar, which is rotatably and slidably fitted into the holding part 7; 13, a fixed leg 15 to which a curved cover 14 is caulked and fixed to the upper part of the locking rod 1;
After fitting it into the through hole 16 drilled in 2, the tip of the fixing leg 15 was fixed to the locking rod 12 by caulking the tip of the fixing leg 15 through the caulking hole 17 on the back side of the metal fitting body 1 formed by both notches 3, 3. It's a knob. Reference numeral 18 denotes a locking metal fitting consisting of a metal fitting body 1 and a locking rod 12.

Next, the procedure for manufacturing the metal fitting body 1 from the metal fitting member 4 will be explained below based on FIG. 2. A plate-shaped member made of metal, particularly stainless steel, with a thickness suitable for the metal fitting body 1 is punched and cut to form notches 3 at both left and right ends (Fig. 2-A), and then both left and right ends are turned to one side. After the protrusion 20 is formed by vertically bending and pressing at approximately the same height as the protrusion 8 (FIG. 2-B), a required interval is placed near the upper part of the longitudinal center of the flat plate part 19. Punching and pressing is performed so that three cutting parts 2 are formed (FIG. 2-C).

Next, a tubular protrusion 5 was formed on the opposite side of the protrusion 20 by pressure pressing at the longitudinal center of the flat plate part 19 where the cut part 2 was formed (FIG. 2-d), and then the three cut parts 2 were formed on the opposite side of the protrusion 20. After cutting the central part of the hole to form the communication opening 3 (FIG. 2-E), cut the parts with both protrusions 20 inward, leaving the same width as the pedestal 6.
Bend and press at 45°. (FIG. 2-F) Next, the parts where both protrusions 20 are located are further bent inward and pressed to stack the base 6 parts, and the protrusions 20 are overlapped to fit inside the tubular protrusion 5. The metal fitting main body 1 is formed by protruding and forming a protrusion 8. (FIG. 2-G) This locking metal fitting 18 is used in exactly the same manner as the conventional locking metal fitting 34.

In this case, the metal fitting body 1 of the locking metal fitting 18 is mainly made by punching, cutting, and bending press processing, thereby making it possible to eliminate the need for the conventional retaining plate 22 and welding work. ，
By stacking the tubular protrusions 6 and protruding the protrusions into the interior of the tubular protrusion 5, its mechanical strength can be significantly increased.

In addition, the knob 13 connects its fixed leg 15 to the locking rod 12.
Since the fixing leg 15 can be inserted into the through hole 16 and the bottom can be caulked using the caulking hole 17 provided on the back side of the metal fitting main body 1, the fixed leg 15 is securely held and will never fall off like in the conventional case. Without,
In addition, it is equipped with cover 14, so knob 1
No damage or accident will occur due to operation 3.

Also, when the knob 13 is pushed down to the locking part 10, the fixed leg 1
Since the knob 5 is placed in the recess 10', even if something touches the knob 13, it will not be woken up, so there will be no damage accident like in the conventional case.
