Description

[Detailed description of the invention] The present invention is a door frame connecting device, or the upper and lower frame back surfaces of the shutter frame of a sash frame with a shutter frame, the vertical frame on the door compartment side of the sash frame, and the door compartment frame are connected via a connecting member. This invention relates to a door bag frame connecting device.

Recently, as a door bag for a storm door, the upper and lower frames and the vertical frame on the bottom side of the door are simply assembled in a U-shape, and the upper and lower frames are connected to one end of the window frame with a connecting metal fitting, and the vertical frame is connected via a bracket. A door frame with a simple framework fixed to the outside wall of a building has been proposed. This type of door frame has a simple structure, so it can be easily installed, but its strength against the load of the shutter is weak, and when storing the shutter, the entire door bag may bend and deform due to the load of the shutter on the lower frame of the door. In some cases, the consistency with the window frame deteriorated, making it impossible to smoothly insert and remove the shutters.

The present invention solves the above-mentioned drawbacks, and in particular, although the structure is simple, it prevents the door pocket from bending and deforming.
The purpose of the present invention is to propose a door bag frame connecting device that allows a shutter to be smoothly taken in and out of the door bag.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In the figure, symbol A is a sash frame, and the sash frame A is made up of an upper frame (not shown), a lower frame 2, and left and right vertical frames 3, 3 in a rectangular frame. It is provided with a shoji frame part 4 which can accommodate the shutter 11 in a slidable manner, and a shutter frame part 5 which slidably accommodates the shutter 11 on the outdoor side and has one side open.
Next, the door bag frame B is attached to the shutter frame portion 5 of the sash frame A.
are integrally connected. Door bag frame B is upper frame 1
2. The lower frame 13 and the vertical frame 14 at the end of the door are framed in a substantially U-shape, and the door end side of the door bag is open. The opening portion is matched with the opening portion of the shutter frame 5, and the shutter 11 and the inside of the door pocket are connected to the sash frame A via the connecting member 6 in a continuous state.

The connecting member 6 is connected to the sash frame A as shown in FIG.
A member in which an extension piece 17 along the vertical frame 3 of the sash frame A is formed on the indoor side of the base piece 16 fixed to the back side of the door bag frame B, and a frame holding piece 18 is formed on the outdoor side.
The base piece 16 has at least two screw holes 16a, 1
6a, the outdoor side surface of the extension piece 17 is formed into a curved convex shape, and a fitting groove 19 is formed along the longitudinal direction on the side surface of the sash frame A, and the frame holding piece 18 also has a screw hole 18a. is worn. The connecting member 6 can usually be easily obtained by molding a hard synthetic resin.

In addition, a frame member storage recess p is formed in the inner lower part of the extension piece 17 as appropriate depending on the connection mode at the connection part between the door bag frame member and the sash frame member, and the extension piece 1
7 and the frame holding piece 18 is set equal to the width of the door pocket upper and lower frame members connected to the sash frame A.

Next, the door pocket frame B is connected via the connecting member 6 having the above configuration.
When connecting the sash frame A, the upper and lower frame end surfaces of the door bag frame B and the upper and lower frame end surfaces of the shutter frame 5 of the sash frame A are brought into contact with each other, and the base piece 16 of the connection member 6 is The door pocket frame B and the sash frame A are fixed to the back surfaces of the upper and lower frame ends through the screw holes 16a, 16a, and at the same time the fitting groove 19 of the extension piece 17 is inserted into the sash frame A.
outdoor side projecting piece 2 protruding from the vertical frame 3 to the door bag frame B side
0. At this time, the outdoor side surface of the extending piece 17 faces the shutter sliding portion of the door bag frame B. The frame holding piece 18 is fixed to the rising piece 12a and the falling piece 13a of the upper and lower frames 12, 13 of the door bag frame B by inserting a screw through the screw hole 18a. 21 is to prevent falling,
This fall prevention 21 prevents the shutter 11 housed in the door bag frame B from collapsing toward the indoor side and obstructing the sliding movement of the shutter 11 that will be housed later.

As described above, by connecting the door pocket frame B and the sash frame A via the connecting member 6, the door pocket frame B is connected to the upper and lower frames of the sash frame A in a plane, and at the same time, the door pocket frame B is connected to the upper and lower frames of the sash frame A in a plane. It is vertically connected to the vertical frame 3. Therefore, if the connecting member 6 is connected only by the base piece 16, when the shutter 11 is stored on the outdoor side of the door bag frame B, the door bag frame B is likely to bend due to the load of the shutter, but the door bag frame B is not connected. Since the extension piece 17 of the member 6 that protrudes perpendicularly to the surface of the base piece 16 and the sash vertical frame 3 are fitted together, the member 6 is reinforced in the direction of deflection, so that the above-mentioned deflection is prevented. Next, since the outdoor side surface of the extension piece 17 facing the sliding part of the shutter is formed in a curved convex shape, even if the corner part hits the connecting member 6 when the shutter slides, It can pass smoothly along the convex surface and can be opened and closed smoothly.

As explained in detail above, according to the present invention,
The connecting member that is fixed to the back surfaces of the sash frame with the shutter frame and the door bag frame and connects the sash frame with the shutter frame and the door bag frame has a connecting member that protrudes from the vertical frame of the sash frame with the shutter frame toward the door bag frame side. Since an extending piece is formed that extends along the outdoor side protruding piece, and the extending piece is fitted into the outdoor side protruding piece, deformation of the connecting member is suppressed. Therefore, it is possible to effectively prevent the door bag frame from being bent and deformed by the load of the shutter.

In addition, since the outdoor side surface of the extension piece is formed in a convex shape and faces the shutter sliding part of the door bag frame, even if the shutter hits the outdoor side surface of the extension piece when opening and closing the shutter, the above-mentioned storm door It is simply returned to the sliding part side, and sliding of the shutter is not obstructed.
