Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a panel window frame attachment structure.

[Problems to be Solved by Prior Art and Invention] In general, a window frame to be assembled into an opening of a panel such as a steel door is fixed to each panel side with a substantially angle-shaped or O-shaped molded member. While assembling. For this reason, there is a drawback that the workability is poor and it is difficult to join the corner portions of these window frame members and to perform subsequent painting and finishing. It is also conceivable that the end of the window frame member is cut into 45-degree connection cut surfaces and the connection cut portions are brought together to form a corner portion. In this case, one side is fixed with a screw. While the work is in progress, the corner connection cutting part on the other side is often jammed, which causes a problem in that the work is time-consuming and the corner part is assembled in an unclean state.

[Means for Solving the Problems] The present invention was devised with the object of providing a panel window frame mounting structure capable of eliminating these drawbacks in view of the above circumstances. When the window frame inserted into the window opening of the panel is composed of the upper member, the left and right vertical members, and the lower member, the corner portions where these respective members are connected are cut at 45 degrees from each other. It is assumed that the cutting portions are abutted and connected at an angle of 90 degrees, and further, the connecting cutting portions of the upper member and the vertical member have a pivot on the cutting line and at the corner inner edge position. It is characterized by having a structure in which it is foldably connected through.

The present invention, with this configuration, enables the window frame to be assembled without shifting the position and with good workability.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, 1 is a panel such as a metal door, and the panel 1 is a core material such as a core material filled in the panel 1.
The face plate 3 covers the front and back of the panel, and the face plate 3 has a window opening. Further, a U-shaped frame member 4 is fixed to the upper side and both vertical sides of the opening with the legs directed toward the inside of the opening, and a hook-shaped lower side frame member 5 is fixed to the lower side. , Thereby forming a window section.

Then, a window frame for fitting, for example, a glass plate or the like into the frame members 4 and 5 is incorporated, and the window frame is composed of four sides of the upper member 6, the vertical member 7 and the lower member 8. Both the upper member 6 and the vertical member 7 have the same shape and are formed in a hat-shaped cross-section, and the ends of the corners of the members 6 and 7 are cut at 45 degrees. By connecting the connection cutting portions 6a and 7a cut to each other, they can be connected at an angle of 90 degrees, and a window frame with high accuracy can be configured.

Reference numerals 12 and 13 denote connection cutting portions 7 whose bottom surfaces 12b and 13b are cut at the 45 degrees of the vertical member 7 and the upper member 6 of the window frame, respectively.
These metal connecting members are fixed to the bottom surfaces on the side of a and 6a by appropriate means such as spot welding.
Are bent and formed in a substantially U-shape with the bottom surfaces 12b and 13b sandwiched therebetween, and as shown in the exploded perspective view of FIG. 5, one of the U-shaped opening sides is chamfered in a tapered arc shape. And
A through-hole 12a is formed in the tip of the connecting leg 12 on the open leg side, and a tip of the connecting part 13 on the leg side of the open leg protrudes inward in a state corresponding to the through-hole 12a. 13a
Is provided, and the connecting tools 12 and 13 are rotatably connected to each other by fitting the through hole 12a into the pivot 13a.
As shown in FIG. 7, the upper member 6 and the vertical member 7 have the pivot shaft 13a as an axis center in a state in which the upper member 6 and the vertical member 7 are expanded and opened at an angle of 90 degrees, and in a folded state as shown in FIG. It is configured to swing and transform. Then, when the expanded state is set, the connecting and disconnecting portions 7a and 6a come into contact with each other, and the tips thereof are fitted in a pointed shape without being displaced.

Here, when the open leg dimensions (outer dimensions of the U-shape) of the connectors 12, 13 are J and H, respectively, and the plate pressure of the connector is t, the open leg dimension H of the connector is H = J + 2t. In addition, the internal dimension of the upper member 6 in the hat portion (groove width dimension for window glass)
The size is set to be the same as the above, and the hole 12a of the connecting tool 12 can be fitted into the pivot 13a of the connecting tool 13 with one touch, taking advantage of the toughness of the metal open leg shape. When the upper member 6 and the vertical member 7 are connected at the corners, the through holes 12a and the pivots 13a of the connecting tools 12 and 13 are located on the cutting lines of the two connecting cutting portions 6a and 7a and at the corner inner edge position. The upper member 6 and the vertical member 7 are foldably connected to each other about the pivot 13a.

The lower member 8 is formed in a hook shape in cross section, and 9 is a ridge having a long side 9a and a short side 9b having a U-shaped cross section. After being inserted into the forehead, the bottom side 8a of the lower member 8 of the window forehead is pressed while pressing the face plate 3 with the long side 9a of the rim 9 from the inside of the room, and the flat machine screw 1
It is fixed to the lower frame 5 on the panel 1 side by 0. In this case, the ridge 9 may be collapsed by the glass plate,
As shown in FIG. 9, the ridge 9
A plurality of tilt-preventing pieces 9c, which are angle-shaped small pieces, are previously fixed inside the U-shaped pocket. Reference numeral 11 is a blind rivet for fixing the lower member 8 of the window frame to the lower frame 5 on the panel 1 side.

In the embodiment of the present invention constructed as described above, first,
The through hole 12a of the connector 12 fixed to the vertical member 7 is fitted into the pivot 13a of the connector 13 fixed to the upper member 6 to assemble with the three sides of the window frame. At this time, the connecting portion has a hinge structure. It can be folded inward. Then, while folding the vertical member 7 inward and supporting the vertical member 7 by hand, first, the upper member 6 is positioned with respect to the window frame 4,
Fixed with blind rivets 11 and then both longitudinal members 7
By pivoting through the pivot shaft 13a to open the legs and abutting them against the vertical frame 4, the corner portion becomes a right angle of 90 degrees, and the vertical member 7 is also accurately held in a predetermined position. Thus, the vertical member 7 is fixed.

Next, the lower member 8 is placed on the rising edge 5a of the lower frame 5 from the outdoor side and slid into the lower frame 8 and fixed to the lower frame with the blind rivet 11, and the long side 9a of the ridge 9 is fixed. Press the panel face plate 3 with, press the tip of the short side 9b against the bottom surface 8a of the lower member 8 and fix it with the flat machine screw 10.
The lower member 8 can be attached. In this case, if the fall stop 9c is determined to be three places at the center and both ends, it can be prevented from intersecting the center of the screw.

In this way, the window frame can be assembled in the window opening in a state where the vertical members 7 are foldably connected to both ends of the upper member 6, and the upper member 6 is positioned at a fixed position to form a blind. After fixing with the rivet 11, the vertical member 7 is connected to the connecting tool 13.
When the legs are opened by pivoting through the pivot shaft 13a until they come into contact with the vertical frame 4, the connecting / disconnecting portion 6 of both members 6, 7 is cut.
Since a and 7a are closely connected to each other with an angle of 90 degrees, the three sides of the window frame are accurately positioned, and the assembly is performed with high accuracy. Can be done very easily.

In addition, since a fall prevention piece 9c is provided on the inner side of the ridge 9, the ridge 9 itself does not fall or shift due to the weight of the glass plate, and any special tool can be used in a stable state. Without this, work can be performed easily and efficiency can be improved.

Further, the window frame member can be pre-painted before installation, and can be molded from a color steel plate or the like, and it is difficult to spray the corner portion after assembling the window frame as before,
Complicated post-finishing can be omitted, which contributes to simplification of incorporation into the window frame.

[Effects] In summary, since the present invention is configured as described above, the upper member of the window frame and the left and right vertical members are preliminarily foldably connected and assembled in this state into the window opening, After the members are fixed, both vertical members are opened and fixed, whereby the assembling can be carried out, so that the window frame can be assembled very easily.

Moreover, since the upper member and the vertical member are foldably connected using a connecting tool whose folding pivot is located on the connecting line of the connecting and cutting portions cut at 45 degrees, the upper member and the vertical member are connected to each other. When expanded to 90 degrees, the edge edges of the cut parts of both members come into contact with each other without being trivially set, and they are accurately set in position, so that
It is possible to easily and surely avoid the corner connecting / disconnecting portion from being attached in an unnatural state due to being jammed.
