Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a shutter panel equipped with a removable lock.

[Conventional technology]

Conventionally, in the case of shutters with drop locks, an operating section for locking and unlocking has been provided near the lower stile or the upper part thereof.

[Problem that the idea aims to solve]

Therefore, it is necessary to operate the knobs etc. in an unnatural posture by bending down, which is inconvenient. When installing a long lock rod in order to raise the operating position, it was necessary to install it inside the door panel for reasons of appearance and strength, but in this case there were problems such as a complicated mechanism.

[Means to solve the problem]

Therefore, in the present invention, the lock rod 3 is made up of a shutter body provided inside the door panel and an operating part 9 of the lock rod 3, and the lock rod 3 has a holder 12 at its upper part and is designed to penetrate the lower stile material 4. It is mounted to be movable up and down through the hole 6 and the through hole 8 of the support member 7 provided in the middle of the door surface, and the operating portion 9 has a rod holding protrusion 20 that is linked to the operating knob 11.
The above-mentioned difficulties have been solved by providing a storm door with a lock in which the holder 12 is connected and held in such a way that it can be attached and detached when the case 10 of the operating section 9 is attached and detached.

[Effect]

With the above structure, the lock rod can be locked and unlocked using the high-positioned operation knob that is easy to operate. Since the lock rod is housed inside the door plate and the operating section 9 is separate from it, it can be detachably held and connected when the case 10 of the operating section 9 is attached and detached, and the operating section 9 is easy to manufacture. , assembly becomes easier.

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing the shutter of the present invention, and FIG. 2 is a longitudinal sectional view of the main part. FIG. 3 is a front view of the operating section, FIG. 4 is a rear view thereof, and FIG. 5 is a longitudinal sectional view at the center thereof. FIG. 6 is a plan view of the operation unit case. As seen in these embodiment drawings, a long lock rod 3 is provided vertically in the front panel 1 and back panel 2 of the door plate, and this lock rod 3 is attached to the lower frame material 4.
It is supported vertically by a through hole 6 of the inner rod receiver 5 and a through hole 8 of a support member 7 provided in the middle of the door surface.
A lockable operation knob 11 is attached to the case 10 of the operation section 9 fixed to the support member 7 so as to be interlocked with the lock rod 3. A holder 12 is fixed to the upper part of the lock rod 3, and recesses provided on both sides of the holder 12 are held by projections 20 of a slide plate 16 shown in FIG. 2, which will be described later. The detailed structure of is shown in FIGS. 3 to 6. A stepped sliding hole 13 is provided on the top surface of the case 10.
A lock plate 15 and a slide plate 16, which are integrated with a pin 14 in the middle, are inserted through this. Lock plate 1
5 has an operating knob 11 at its upper end, a locking notch 17 and a curved portion 18 at its lower part, and its lower end is elastically supported by a spring 19 to a case 10. The slide plate 16 has two rod holding protrusions 20, 20 provided in its middle portion, and its lower end projects outward from a slide hole 21 provided in the case 10. With this structure, the rod holding protrusions 20, 20 are connected to the holder 1 of the lock rod 3.
While pressing the case 10 of the operation part into the recess of 2.
It can be integrated by screwing it to the support member 7 housed in the door plate. To operate the lock, press the operating knob 11 against the spring 19.
By pressing the lock plate 15 downward, the curved portion 18 of the lock plate 15 descends along the sliding hole 13, and the lock rod 3 also descends as the locking notch 17 engages with the upper edge of the case 10. Further, the lock rod 3 can be pulled up by the spring 19 by simply moving the operating knob 11 to the left in FIG. 3, making unlocking easy. Since the present invention is characterized in that the operation part is provided at a higher position than the conventional structure, the holder 12 provided at the top of the long lock rod 3 is not limited to the above example. For example, the structure of the lock plate, slide plate, rod holding protrusion, etc. can be changed freely as long as it is lockable and the operation knob is interlocked with the lock rod.

[Effect of the idea]

With the above structure, the lock can be operated in its normal position without major changes to the door plate structure, making it easy to lock and unlock storm doors, etc. The effect of easy manufacture can be obtained.
