DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface lattice unit for windows. More specifically, the vertical lattice constituting the window surface lattice unit can be freely extended and contracted according to the size of the window frame, and can be extended in the horizontal direction according to the width of the window. The present invention relates to a surface lattice unit for a window which can be assembled and attached to a rain shield plate portion of a sash vertical frame from the inside of a room.

2. Description of the Related Art A conventional aluminum sash window lattice is constructed by a professional contractor at the time of building construction, procuring materials at their own discretion, and adjusting the dimensions according to the window frame size of each building individually. The vertical and horizontal grids were cut, drilled, bolted, assembled and mounted on window opening frames.

[0003]

However, the conventional surface lattice for aluminum sash windows is mainly made of a metal product such as aluminum, and is exposed to the wind and rain to deteriorate its structure or deteriorate its appearance. It requires specialized tools and knowledge to cut and drill metal products when replacement is required, etc., and cannot be handled by ordinary users, especially for screen grids attached to windows on the second floor or higher. Needed scaffolding and had to hire a professional contractor. In addition, despite the diversification of consumer needs today, there is a problem that users are not always satisfied in terms of colors and shapes because they are limited to the products handled by the contractor who requested them. I was

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional window screen grid, and has as its object to provide various window screen grid assembly sets sold at stores. The general user selects and purchases according to his / her preference, takes it home, and adjusts the size of the screen grid according to each window frame size using only ordinary household tools (hammers and a screwdriver). It is an object of the present invention to provide a window lattice unit which can be assembled by itself and attached to a window opening frame from the inside of a room.

Means for Solving the Problems In order to achieve the above object, a window surface lattice unit according to the present invention is characterized in that it is constructed as follows. That is, a hole was provided at a predetermined position.
A hole is provided at a predetermined position with the outer cylinder, and the inside of the outer cylinder is slid.
A plurality of inner cylinders that move freely and adjust the height
And the cross section is U-shaped with a bent portion at the tip.
Punch anchor type
Holes are provided in place to secure with rivets
A plurality of horizontal grids, and the plurality of vertical grids and the plurality of horizontal grids.
Sash the fixed grid at the appropriate height of the window frame.
Nipping part and front for driving and fixing it to the rain shield part of the vertical frame
And a receiving plate for holding and fixing the bent portion of the horizontal lattice
It is characterized by having a plurality of engaging metal fittings, and by connecting the horizontal grids of adjacent surface grids using a connecting metal fitting, the horizontal grid can be extended in the horizontal direction according to the window width. Features.

Each vertical grid constituting the window surface grid unit is composed of an outer cylinder and an inner cylinder, and the inner cylinder is slidably inserted into the outer cylinder. That is, both are a two-stage type that can expand and contract freely so that it can correspond to window frame sizes of various heights, and ordinary users can adjust the size according to the size of the window frame at home, each having a different size. Without cutting the alignment, the length of the vertical lattice can be appropriately adjusted, and then the horizontal lattice can be locked and joined. If the window width is larger than the horizontal lattice length of the window surface lattice unit,
By connecting the horizontal lattices of another window surface lattice unit, the surface lattice can be extended in the horizontal direction according to the window width.

[0007] It is preferable that the vertical grid and the horizontal grid are fastened with a punch anchor type rivet. The punch-anchor-type rivet can be easily and securely fastened without using bolts and nuts because the rivet tip is easily and firmly opened by hitting the rivet head with a hammer or the like. The vertical lattice and the horizontal lattice are preferably made of aluminum used for a normal window surface lattice in terms of weight reduction and robustness, but may be made of other non-rusting metal.

[0008] The attachment of the surface lattice to the window opening frame is performed via an engagement fitting provided with a holding portion at a side end. That is, first, the holding portion of the engagement fitting is driven into the rain shield plate portion of the sash vertical frame using a hammer and fixed. An appropriate fixing position is a position where the window glass can be entirely protected when the horizontal lattice of the plane lattice is inserted. Next, the height of the assembled surface grid is reduced and the window grid is brought out of the window, and the bent plate portions at the ends of the horizontal grid are inserted between the engagement metal fittings and the receiving plate, respectively. It can be attached by firmly crimping with a screw. In this way, the general user can easily attach the window surface lattice unit to the window opening frame from inside the room without drilling the horizontal lattice and the window opening frame with a drill or the like.

First, in order to assemble a surface lattice 1 of a window surface lattice unit as shown in FIG. 1, a vertical lattice 2 is arranged on a floor, and a horizontal lattice 3 is placed on the vertical lattice 2 as shown in FIG. And a hole (not shown) provided in the vertical lattice 2 and a hole 4a provided in the horizontal lattice 3 are aligned with the hole 4a of the punch anchor type rivet 4. Insert Since the punch anchor type rivet 4 has the flange portion 4c on the body portion 4b, it does not fall out even when inserted. Thereafter, when the head 4d of the punch anchor type rivet is hit with a hammer or the like, the diameter of the body 4b is increased, and the vertical lattice 2 and the horizontal lattice 3 can be firmly integrated.

Next, the holding portion 5b of the engagement fitting 5 shown in FIGS. 5 and 6 is driven and fixed to the rain shield plate portion of the vertical sash frame 6 using a hammer or the like. Since the horizontal lattice 3 of the plane lattice 1 of the window plane lattice unit body is provided at two locations above and below the plane lattice, it is necessary to drive the engaging metal fitting 5 into an appropriate position to protect the window glass.
