Description

[Detailed Description of the Invention] The present invention relates to a connection device for a shutter frame and a door pocket frame, which connects the shutter frame and the door pocket frame by a connector provided with an expanding sliding portion.

The conventional connection device for the shutter frame and the door pocket frame is such that the edge of the shutter frame, which is slightly wider than the thickness of the shutter, is brought into contact with the opening of the door pocket, which is approximately the same width as the shutter frame. It was common to connect them with simple connectors. When storing the shutter in the door pocket, slide the shutter along the shutter frame and push it straight into the door pocket from the opening. The shutter was moved laterally to the head panel side using a guide, and then the rear part of the shutter was moved to the head panel side, and the entire shutter was stored in the door pocket. Also, when removing a shutter from the door pocket, the rear part of the shutter was moved laterally to the opening, and then the shutter frame was pulled out.

As described above, the conventional connecting device for connecting the shutter frame and the door bag frame has the disadvantage that the connection part between the shutter frame and the door bag frame is narrow, so it is relatively troublesome to put the shutter in and take it out of the door bag, and it cannot be done smoothly. Ta.

The present invention was made in view of the above-mentioned drawbacks, and involves connecting the door bag side end of the storm door frame and the door bag opening with a connector provided with an expanding sliding part, and expanding the connecting part. By forming it, it is possible to easily and smoothly take the shutter in and out of the door pocket, and
The purpose of the present invention is to provide a connecting device for a shutter frame and a door bag frame, which allows the creation of an expanding sliding part firmly and easily.

Hereinafter, one embodiment of the present invention shown in the drawings will be described in detail.

FIG. 1 is an exploded perspective view of the coupling device, and FIG. 2 is a plan view of the coupling device in an assembled state. In these drawings, reference numeral 10 denotes a shutter frame, which is generally formed from an extruded material of aluminum or aluminum alloy. Reference numeral 11 denotes a bottom plate of the shutter frame 10, which has a width slightly wider than the thickness H of the shutter 40, and an upright wall 12 for guiding the shutter 40 is integrally formed on the outdoor side of the bottom plate 11. Standing wall 12
Forms a seal receiving part 13 with a cross-section shape in the upper part,
A seal member 14 made of mohair or the like is fitted here. Further, a notch 15 is formed at the door bag side end of the storm door frame 10 configured as described above, by cutting out the outdoor side upright wall 12 by an appropriate length. Furthermore, a mounting hole 16 is bored at the end of the bottom plate 11 of the shutter frame 10 on the door bag side.

Reference numeral 20 denotes a door bag frame made of the same material as the shutter frame 10, and the door bag end plate 20a is cut out by a width approximately twice the thickness H of the shutter 40 at the part that contacts the shutter frame 10 to form an opening of the door bag. 22 is formed.
Reference numeral 23 denotes a bulge formed at the opening side end of the anti-tilt 21. The portion that contacts the shutter 40 is curved, and a rotary wheel 24 is attached thereto. By providing the curved bulge 23 on the opening 22 side of the anti-tilt 21 and attaching the rotary wheel 24 in this way, the shutter 40 can be moved extremely smoothly, making it easy to take it in and out of the door pocket. Also, 25 is shutter 4
The guide for lateral movement of 0 is attached to the door case frame 20 on the side opposite to the opening 22 in the door case, and moves the front part of the storm door 40 pushed in from the opening 22 in the lateral direction. 26 is the mirror plate of the door pocket, 2
7 is a mounting hole drilled in the bottom plate 28 of the door bag frame 20.

30 is a connector, which connects the above-mentioned shutter frame 10 and door bag frame 2.
0 are connected to form a connecting device as a whole. 3
Reference numeral 1 denotes an L-shaped connection mounting plate for the connector 30, which is located below the bottom plate 11 of the shutter frame 10 and the bottom plate 28 of the door bag frame 20, and has mounting holes 16 and 16 bored in the bottom plates 11 and 28, respectively. 27 and corresponding mounting hole 32
is drilled therein, and is fixed with screws (not shown). Reference numeral 33 denotes an expanding sliding portion formed inside the bent portion of the connecting mounting plate 31, which allows the shutter frame 10 and the door pocket 20 to
The sliding bottom plate 33 is formed higher than the top surface of the connecting mounting plate 31 to a height corresponding to the top surface of the bottom plates 11 and 28.
a and a sliding wall 33b provided upright on the side edge of the sliding bottom plate 33a.
The expansion sliding portion 33 expands by approximately the same width as the thickness H of the shutter 40 from the side that contacts the notch 15 of the shutter frame 10 toward the side that contacts the opening 22 of the door pocket. ing. Reference numeral 34 denotes a fitting piece protruding from the end of the sliding wall 33b on the side of the notch of the shutter frame 10, which fits into the end of the seal receiving part 13 of the upright wall 12. 3
Reference numeral 5 designates an engaging piece protruding from the end of the sliding wall 33b on the door bag side, which engages with a step 21a formed on the opening 22 side of the anti-tilt 21.

Therefore, when assembling this coupling device, proceed as follows. A shutter frame 10 and a door frame 20 are attached to predetermined positions of an opening of a house such as a window, and the end of the shutter frame 10 and the opening 22 of the door frame 20 are brought into contact. Next, the fitting piece 34 of the expansion sliding part 33 is fitted into the seal receiving part 13 of the upright wall 12 from the notch 15 of the shutter frame 10, and the engaging piece 35 of the sliding part 33 is fitted into the opening 22. Then, it is engaged with the stepped portion 21a of the stopper 21. In this way, a sliding portion that gradually expands from the notch 15 of the shutter frame 10 to the opening 22 of the door pocket is formed at the portion connecting the shutter frame 10 and the opening 22 of the door pocket. In this state, connect the mounting hole 32 of the connection mounting plate 31 of the connection tool 30 and the shutter frame 1.
Align the mounting holes 16 of 0 and the mounting holes 27 of the door frame 20, and fix them from below with a fixing member such as a screw (not shown) to connect the shutter frame 10, the door frame 20, and the connector 30 together. Connect firmly to each other.

In the connecting device of the above embodiment configured in this way, the front and rear parts of the shutter 40 are guided by the lateral movement guide 25 and the expansion sliding part 33, respectively, to take the shutter 40 in and out of the door pocket. This can be done while moving the entire shutter in parallel, making it very easy to take the shutter in and out. Note that even if there is no lateral movement guide, the shutter 40 can be moved in and out while being moved horizontally as desired by the expansion sliding portion 33, so the work of putting in and taking out the storm door is much easier than in the conventional case. Therefore, a guide for lateral movement is not necessarily required.

Note that the length of the notch 15 of the shutter frame 10, the width of the opening 22 of the door pocket, etc. can be changed as appropriate depending on the type of shutter, the size of the door pocket, etc.

As described above, according to the present invention, a notch is formed at the end of the shutter frame on the door bag side, the opening of the door bag is opened wider than the width of the shutter frame, and the expanding sliding part of the connector is moved from the notch. Since it is provided so as to gradually expand toward the opening, the shutter can be easily taken in and out of the door pocket. In addition, since the connector has an expanding sliding part that makes it easy to take the shutter in and out,
A solid expansion sliding part can be easily created.
