Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hanging wheel device for a folding window.

Conventional technology For example, as described in Japanese Utility Model Application Publication No. 53-126345,
A rectangular frame-shaped handle frame with wheels attached to the upper end that roll along guide rails installed on the window upper frame is fitted onto the upper side of the shoji and fixed with screws. Some have a structure in which they are assembled by penetrating the T-shaped locking rod that connects and separates the frame.

Problems to be Solved by the Invention In the conventional example described above, the rectangular frame-shaped handle stile is fitted onto the shoji and fixed with screws, so the work of assembling it onto the shoji is complicated. Moreover, it is not possible to absorb processing errors in the positional relationship between the window upper frame and the shoji.

Furthermore, since the handle stile is shaped like a square frame, it is not always possible to assemble the locking rod through the handle stile smoothly.

Means for Solving the Problems The present invention was devised for the purpose of eliminating the drawbacks of the conventional example. A mounting tube to which a moving wheel is attached is passed through a bracket provided on a shoji frame, and a nut is screwed into a screw provided at the lower end of the mounting tube that protrudes from the bracket, and the locking method is used to release the upper frame of the window. The rod is assembled by penetrating the mounting tube.

Embodiment The drawing shows an embodiment of the hanging wheel device according to the present invention, A is a hanging wheel, 1 is a mounting tube for the hanging wheel A, the mounting tube 1 has a screw a on the lower end circumference side, and the upper end is attached to the main frame. 2
It is interposed between the side pieces 3, 3 and welded to the side pieces 3, 3 to each other.

The main frame 2 is composed of a central piece 4 and the pair of side pieces 3, 3, and is assembled by passing a wheel shaft 7 through a bearing tube 5 installed between the side pieces 3, 3. A hanging wheel A is constructed by attaching wheels 6, 6 to both ends of a wheel shaft 7 that protrudes from the side pieces 3, 3.

Illustrated 8 is a vertical stile of a shoji D. The vertical stile 8 has pieces 8b, 8b protruding outward from both indoor and outdoor ends of an outer piece 8a of a hollow main body 8' to form a space at the outer end opening. A bracket 9 is engaged in the gap 8'' of the vertical stile 8, and the bracket 9 is attached to the outer piece 8a.

The bracket 9 is composed of a first member 9a and a second member 9b shown in FIG.
A screw (not shown) is screwed into the outer piece 8a through the upper and lower pair of through holes 10, 10 on one side and tightened, and the vertically long hole 11 provided in the first member 9a is tightened.
A locking piece 12 protruding from the second member 9b is locked to combine the second member 9b with the first member 9a, and a pair of upper and lower through holes 10'', 1 provided in the second member 9b are assembled.
0'' coincides with the other pair of upper and lower through holes 10', 10' provided in the first member 9a, and these through holes 1
The vertical stile 8 is provided with screws (not shown) through holes 0' and 10'' that are screwed and tightened to the outside piece 8a.

The guide rail 1 has the wheels 6 of the hanging wheel A mounted on the window upper frame 14 in the vertical hole 13 formed by the bracket 9.
5, and the mounting cylinder 1 of the hanging wheel A is passed through from the upper end of the vertical hole 13, and the bracket 9
The washer 16 and the washer 17 are engaged with the lower end of the mounting tube 1 that protrudes further, and the nut 18 is screwed onto the screw a.The shoji D is tightened while adjusting the height position of the shoji D with respect to the window upper frame 14. It is attached to the window frame B via the hanging wheel A.

19 in the figure is a locking rod whose upper end engages and disengages an engaging member 20 provided on the window upper frame 14, and the locking rod 19 is a hanging wheel A.
pass through the mounting tube 1 of and assemble it to the hanging wheel A,
A connecting piece 2 is attached to the screw part b at the lower end protruding from the mounting tube 1.
The lower piece 21'' of the connecting piece 21 is inserted into the hollow main part 8' of the vertical frame 8 through the window 22 provided in the outer piece 8a, and the vertically moving frame 2
It is installed on 3.

Note that the locking rod 19 is assembled by screwing the upper piece 21' of the connecting piece 21 onto the threaded portion b in advance, and penetrating the mounting cylinder 1 of the hanging wheel A assembled into the shoji vertical stile 8 from below. , the lower piece 21'' of the connecting piece 21 is inserted into the hollow main body part 8' through the window hole 22, and the vertical movement rod 2 is inserted.
3 and assembled to the hanging wheel A while adjusting the engagement relationship with the engaging member 20 using the groove 24 provided at the lower end.

Further, the vertically moving rod 23 is vertically moved by operating the operating handle 24, and as the vertically moving rod 23 is vertically moved, the locking rod 19 is vertically moved via the connecting piece 21 to lock the engagement member 20. They are starting to separate.

Effects of the invention According to the invention, the hanging wheel is easy to assemble because it is only necessary to pass the mounting tube through the bracket provided on the shoji frame and screw a nut onto the threaded portion at the lower end of the mounting tube that protrudes from the bracket. You can get the equipment and also
Since the height of the shoji relative to the window frame can be adjusted by operating the nut, processing errors in the positional relationship between the window frame and the shoji can be absorbed.

Furthermore, since the locking rod can be assembled by simply passing it through the mounting tube along the shape of the attachment tube, the work can be easily performed, and the hanging wheel device can be made smaller as a whole.
