Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for attaching window products such as a surface lattice.

[0002]

2. Description of the Related Art Conventionally, surface lattices and the like for crime prevention and decoration are attached to windows of houses and the like. These are installed for each purpose, but they hinder evacuation in the event of a disaster. Therefore, an area lattice that can be opened and closed in the form of an accordion or shutter was introduced so that it would not hinder evacuation in an emergency.

[0003]

However, in the above surface lattice, not only the design and specifications are limited, but also the structure has to be complicated as compared with the general one. Therefore, it is relatively expensive, but on the other hand, it may be installed outdoors, so that it is likely to cause a failure and may be unusable in an emergency.

The present invention has been made in view of the above circumstances, and provides a surface-lattice stopper for easily removing a general surface-lattice or the like even if it is attached to a window. To aim.

[0005]

A surface lattice stopper according to the present invention made to solve the above problems comprises a stay for fixing to a frame and a connecting member for fixing to a surface lattice. Has a slide pin with a hooking portion protruding from the head, and the connecting member has a keyhole-shaped hole that can be slid and locked after inserting the slide pin. It is characterized in that a pin stopper that holds the hole in a non-sliding manner is fixed through a bendable tongue piece. The slide pin and the punched hole or the pin stopper may be provided on either the stay or the connecting member, or ribs that fit with each other may be provided along the longitudinal direction of the stay and the connecting member.

[0006]

With the use of a keyhole-shaped hole and a slide pin coupling means, the attachment / detachment is facilitated, and a pin stopper is provided to prevent the connecting member from being naturally detached from the stay. In addition, by providing ribs that fit with each other along the longitudinal direction of the stay and the connecting member, the strength of the metal fitting is increased and the vertical movement of the connecting member with respect to the stay is prevented.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of a surface lattice stopper according to the present invention will be described below in detail with reference to the drawings. In this embodiment, the stay 2 and the connecting member 4 are made of a rectangular metal plate made of iron or stainless steel.

The stay 2 has a holding portion 12 formed at one end thereof by bending the end portion into a U shape, and at the other end portion thereof.
A slide pin 7 is provided which vertically projects from either one of the front and back surfaces and has a hook portion 6 formed on the head portion 5.
The connecting member 4 has the slide pin 7 at one end thereof.
A through hole 8 for sliding and hooking after insertion is formed, and the other end portion is bent substantially at a right angle and a connecting portion 14 for holding the surface lattice 3 is provided. For the stay 2 and the connecting member 4,
Rounded ribs 11 that fit with each other are provided along the lengthwise direction, and a pin stopper 9 that holds the slide pin 7 in a slidable manner with respect to the hole 8 is bent in the connecting member 4. It is secured via possible tongues 10.

The slide pin 7 has at least the connecting member 4.
And the pin stop 9 have a height that is the sum of the thicknesses of both, and the head that can be hooked to the edge of the punched hole 8 at a position separated from the surface of the stay 2 in the slide pin 7 by the thickness of the connecting member 4. 5 is formed. The head 5 may have at least the hooking portion 6, but the slide pin 7 facing the holding portion 12 side may be provided in order to prevent the pinning 9 from coming off at all times.
It is enough to keep the side of the body warped.

A large hole 15 through which the head 5 of the slide pin 7 is inserted with a margin is formed in the hole 8 for locking the slide pin 7.
And a long hole 16 with which the hooking portion 6 of the slide pin is hooked are integrally formed in a keyhole shape, and the stay 2 and the connecting member 4 are separated by pushing the surface lattice 3 along its longitudinal direction. Thus, the elongated holes 16 are provided closer to the surface lattice 3 than the large holes 15. This is because, in the event of a disaster, since the person may be upset, it is considered that the push-pull form is more effective than the pull-pull form.

The pin stopper 9 is attached to the tip portion of the metal tongue piece 10 which is bent similarly to the connecting member 4 and the head portion 5 of the slide pin 7.
A hooking hole 17 for hanging a hook is formed, and a warp portion 18 is provided at the tip of the hooking hole 17 so that a finger can be easily hooked. Although this pinning also needs some strength, it is preferable to use a relatively soft metal or a metal having elasticity such as a leaf spring so that the warp portion 18 can be bent easily by pulling it up with a finger. desirable. Further, instead of forming the hook hole 17, the metal tongue piece 10 is bent to form the head 5
It is also possible to form a concave portion 19 capable of accommodating therein. Further, if the contact portion 20 of the pin stopper 9 is tilted in accordance with the warp of the side surface of the slide pin 7 facing the holding portion 12, the head 5 of the slide pin 7 slides into the back of the pin stopper 9. Can be prevented.

This embodiment is constructed as described above. When the pin 9 is pulled up and the surface lattice 3 is pushed by hand or foot, the slide pin 7 slides through the long hole 16 to reach the large hole 15, and the surface lattice 3
Tries to drop together with the connecting member 4 in the area limited by the large hole 15 due to its own weight. At that time, rib 1 of stay 2
If 1 is provided so as to project toward the side on which the slide pin 7 is formed, the front surface of the stay 2 and the back surface of the connecting member 4 are separated along the roundness of the rib 11, and the slide pin 7 automatically draws the hole 8.
Break away from The fastener of the present application does not have to be used for all the fasteners to which the surface lattice 3 is attached, and may be used to the extent that a necessary evacuation route can be secured.

The means for fixing the stay 2 and the skeleton 1 may be a means for fixing to the sash vertical frame 22 of the skeleton 1 by the sandwiching portion 12, or may be a screw for fixing to the outer wall of the skeleton 1. The fixing means for the 4 and the surface lattice 3 is not particularly limited, and may be one in which the tip end is fitted into the horizontal rail 23 of the surface lattice 3 and screwed. Even the connecting member 4 does not necessarily have to be bent and may have a linear shape.

The slide pin 7 and the punch hole 8 may be provided as a pair in either the stay 2 or the connecting member 4, but whether the push pin is removed or pulled out is a long hole in the punch hole 8. Care must be taken because it depends on the positional relationship between 16 and the large hole 15. Further, in order to obtain the action of the slide pin 7 being automatically separated from the hole 8, the rib 11
Is preferably formed so as to project to the side where the slide pin 7 is provided. For example, if the unprocessed portion 21 is provided at the end of the connecting member 4 as shown in FIGS. 3 and 4, the stay 2 and the connecting member 4 are provided.
Even if there is no vertical displacement between the and, the connecting member 4 is pushed toward the rib 11, so that the unprocessed portion 21 of the connecting member 4 rides on the rib 11 of the stay 2 and both the stay 2 and the connecting member 4 Automatically separates. This action becomes more remarkable by setting the height of the slide pin 7 lower than that of the rib 11 of the stay 2.

[0015]

As described above, by using the surface lattice stopper according to the present invention, it is possible to easily secure an evacuation route in the event of an emergency and the stopper itself has a very simple structure, which can prevent rain.
It can maintain its function for a long time even when exposed to snow and sunlight. Further, the area lattice can be widely selected for the design and the specification, and even if any area lattice is selected, the area lattice itself to be used is a very general one, which is extremely inexpensive. Further, even when repair or the like is required, the surface lattice or the like can be replaced very easily.
