Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a metal fitting for raising and lowering a shutter pillar for fixing the shutter pillar at a predetermined position.

[Conventional technology]

Generally, the raising and lowering metal fitting is composed of a case attached to the lower part of the center pillar, and a U-shaped rod which is a dropping rod which penetrates the case vertically and can be inserted into and removed from a tray attached to the floor.

Further, the tray has a box shape, and an opening is formed on the upper surface for inserting the tip side of the U-shaped rod of the lifting metal fitting, and the upper surface is placed on the floor below the lifting metal fitting when the center pillar is mounted. It is exposed and buried.

The operation of the lifting and lowering metal fitting is performed as follows. In the case of mounting the middle pillar, after the middle pillar was positioned at a predetermined position, the U-shaped rod of the lifting metal fitting was moved downward to insert the tip end side into the saucer of the floor. Next, when removing the center pillar, the U-shaped rod of the lifting and lowering metal fitting was moved upward to remove the tip end side from the receiving tray.

[Problems to be solved by the invention]

However, the above-mentioned conventional raising and lowering metal member is formed so that the tip end side of the U-shaped rod is tapered so as to be slightly inward.
By simply inserting the shaped rod into the opening of the tray, the operating force (2 kgf to 3 kgf) is hardened by using the beam of the U-shaped rod to prevent the skid from climbing up. At the same time, in the case of strong wind such as a typhoon or the like, the U-shaped rod tends to come off from the pan as it gradually slides up against the impact from the outside.

The present invention was created in view of the above problems, and has good operability when raising and lowering a drop rod such as a U-shaped rod,
The purpose of this is to provide a metal fitting for raising and lowering the middle pillar of the shutter that will not let the falling rod slide up even in the event of a strong wind such as a typhoon.

[Means for solving problems]

In order to solve the above problems, according to the present invention, a hollow case attached to the inner side of the lower part of the middle pillar and a parallel leg having a parallel leg are vertically inserted through the case to be inserted into a tray on the floor. In a raising / lowering fitting for a shutter pillar, which is composed of a dropping bar to be removed, a claw portion having a J-shaped cross section is fixed to a shaft member at an upper part of one leg of the dropping bar in the case, penetrates an upper surface of the case, and has a lower end at a lower end. A lever member formed with a shaft is rotatably supported by the shaft member in a state in which the pawl portion is urged toward the center pillar, and the pawl portion of the lever is hooked vertically below the lever member. The locking member is fixed to the case, and a spring member is provided below the other leg of the drop rod in the case to urge the drop rod upward.

[Action]

By adopting the above configuration, since the claw portion of the lever member is hooked to the hooking member by the downward movement of the drop rod,
Compared to the conventional drop bar that required taper to operate, it can be hooked with a lighter operation, and its hooking is more reliable, so it is also resistant to external shocks during strong winds such as typhoons. However, there is no fear that the dropping stick will slide up. To remove the hook of the drop bar, push the U-shaped bar downward and push down the end of the lever member that penetrates the hole of the case toward the center pillar side. The member and the retaining member are disengaged from each other, and the urging force of the spring member provided on the retaining rod causes the retaining rod to move upward to restore the original state.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of a partially cutout showing a lifting metal fitting and a saucer attached to a center pillar, FIG. 2 is a sectional side view of the lifting metal fitting and a saucer, and FIG. 3 is a rear view showing the structure of the lifting metal fitting. Figure,
FIG. 4 is a sectional view taken along the line IV-IV in FIG. 3, and FIG. 5 is a sectional view showing the engaged state of the lever member and the retaining member.

The raising / lowering metal fitting A is attached to the inside of the shutter lower pillar B on the indoor side, and the lower position floor portion C has a saucer D similar to the conventional example, and the upper surface openings 1 and 1 thereof are exposed to the floor portion C. It is buried under the condition. The lifting metal fitting A has a hollow case 2 in the center thereof.

Holes 2a, 2b, 2c, 2d on the upper and lower surfaces of the case 2
A U-shaped rod 3 having legs 3a and 3b extending in parallel is inserted into the through hole through the through hole, and the opening portions 1, 1 of the tray D are inserted.
It is inserted and removed freely. A collar portion 4 is extended on the back side of the lifting and lowering metal fitting to position the center pillar B, and the holes 5a, 5b, 5c on the rear surface of the lifting and lowering metal fitting A,
5d (see FIG. 3) and a hole (not shown) in the flange portion fix the middle pillar B via a screw.

The raising and lowering metal fitting A of the present invention is constructed as follows, as shown in FIGS.

That is, the pin 6 which is the shaft member having the head 6a on the center side of the case 2 is attached to one leg 3a of the U-shaped rod of the penetrating portion of the case 2.
Has been inserted. A lever member 7 is loosely fitted in the radial portion of the pin 6, and the lever member 7 is biased toward the head 6a of the pin 6 by a spring 8 also wound around the radial portion.

One end of the spring 8 abuts on the tip side of the lever member 7 to urge the tip side of the lever member 7 to the side of the middle pillar B of the case 2. The tip of the lever member 7 is rotatable on the surface of the case 2 with the pin 6 as a fulcrum.

The other end of the spring 8 is wound around the leg 3a of the U-shaped rod 3. The tip of the lever member 7 is bent to the side of the middle pillar B of the case 2 to form a claw portion 7a, and the end side thereof is the case 2.
It penetrates through the upper square hole 9 and extends upward, and the extending end is bent in a round shape.

A spring steel plate or the like is preferably used for the lever member 7. At the bottom of the case 2 below the lever member 7, the claw portion 7a of the lever member 7 during the downward movement of the U-shaped rod 3.
A lever latch 10, which is a latching member having a latching portion 10a bent toward the surface of the case 2 so as to be latched, is riveted to the surface of the case 2.

On the other hand, on the other leg 3b of the U-shaped rod 3, a pin 11 is attached to the upper side of the case 2. A spring 12 is wound around the leg 3b between the pin and the bottom surface of the case 2, and constantly urges the U-shaped rod 3 upward.

When the U-shaped rod 3 is pressed down and inserted into the tray D by configuring the lifting and lowering metal A as described above, the claw portion 7a at the tip of the lever member 7 serves as a latch member. When the claw 7a of the lever member 7 hits the latching portion 10a of the lever 10, the claw portion 7a of the lever member 7 is pulled toward the front surface side of the case 2 against the biasing force of the spring 8 and is meshed with the latching portion of the lever latch 10 to be latched.

As described above, according to the raising / lowering metal fitting of the present invention, the U-shaped rod is tapered and the operating force is required, so that it can be engaged with a light operation and the engagement is reliable. U against strong winds such as typhoons and against external shocks
There is no fear that the shape rod 3 will slide up.

To release the U-shaped rod 3 from the latch, the end of the lever member that penetrates the hole of the case is pushed down while pushing the U-shaped rod downward, and the claw portion of the lever member rotates. The lever member and the retaining member are disengaged from each other, and the urging force of the spring member provided on the drop bar causes the drop bar to move upward to restore the original state.

[Effect of device]

As described above, according to the lifting / lowering metal fitting of the present invention, since almost no operating force is required for lowering the dropping bar, the operability is good, and the claw portion of the lever member engages with the latching member. Since it is stopped, the drop rod and the hooking member will not be disengaged even in the event of strong wind such as a typhoon, or even if there is rattling in the vertical and front-back directions. Further, in order to release the engagement between the claw portion of the lever member and the engagement member, the drop rod is automatically pushed up by the action of the spring member simply by pressing the lever member toward the center pillar.
