Description

[Detailed explanation of the idea] The present invention relates to a door roller device.

A conventional door roller device is shown in FIGS. 1 and 2. In both figures, a door wheel 1 is rotatably supported by a support member 2, and pivoted 5 in a frame 4 having an opening 3 at the bottom of the support member 2 so as to be swingable up and down. As a result, a portion of the door roller 1 protrudes downward from the opening 3 so that its vertical position can be changed, and the frame body 4 is mounted within the lower stile 7 of the shoji 6. The door roller 1 is at the lowest position A before or when the shoji 6 is erected into the frame, and is at the uppermost position B when the shoji 6 is erected into the frame. Then, by screwing the screw 9 that is screwed into the side outer end 8 of the frame 4, the tip of the screw 9 presses the support member 2 and swings it downward, and after the shoji 6 is installed. Construction adjustments will be made. The position C indicates the lowest adjustment position of the door roller 1 using the screw 9 in this case, and the installation adjustment using the screw 9 is performed within a distance l from the uppermost position B. Further, a guide member 12 that engages with the downward guide groove 11 of the lower frame 10 of the frame is interlocked and connected to the support member 2 within the frame 4 so as to be able to move up and down.
At the lowest position A of the door roller 1, its lowest end surface is located on the same horizontal line as the lowest position A, and its vertical movement amount is set to be larger than the movement amount of the door roller 1.

Therefore, when installing the shoji 6 in the frame, first lift the shoji 6 and insert the upper part into the upper frame rail groove,
The lower part is moved onto the running surface of the lower frame 10 and the guide member 12 is pressed against the vertical wall 13 of the lower frame 10. At this point, the door roller 1 is at the lowest position A, and the lowest end surface of the guide member 12 is also on the same horizontal line. When the shoji 6 is lowered from this state, the load is transferred to the door roller 1, and the door roller 1 becomes the uppermost position B. At the same time, the guide member 1
2 moves upward and engages with the guide groove 11 of the lower frame 10.
This completes the erection of the shoji 6, and then screws 9 are screwed in to adjust the installation.
Since the guide member 12 is engaged with the guide groove 11, the shoji 6 will not come off the frame as long as the door roller 1 rolls on the running surface of the lower frame 10.

However, as shown in FIG. 3, for example, the lower frame 10
If the shoji 6 is bent downward as shown in the imaginary line, the shoji 6 will also be tilted as shown in the imaginary line. Therefore, a gap is created between the retaining member in the upper frame rail and the upper surface of the shoji 6, so that when the shoji 6 is opened or closed or when the shoji 6 comes into contact with the vertical frame 14, the door roller 1 moves against the lower frame 10. A situation occurs where the vehicle lifts off the running surface. As a result, since the support member 2 of the door roller 1 is swingable downward and the amount of movement of the guide member 12 is larger than the amount of movement of the door roller 1, the guide member 12 is moved into the guide groove of the lower frame 10. Shoji 6 off from 11
There was a problem that the image was out of the frame. In such cases, the upper retaining member of the upper frame cannot achieve its purpose.

This invention solves these conventional problems, and even if the shoji shoji rattles due to bending of the lower frame or upper frame, it has a simple structure that allows the guide member on the shoji side to connect with the guide groove on the lower sash. To provide a door roller device which can ensure engagement and prevent a shoji from coming off.

Therefore, the feature of the present invention is that the supporting member, on which the door roller is rotatably supported, is attached to the downwardly opening frame attached to the lower stile of the shoji. In a door wheel device in which the door roller is pivotably mounted in a staggered manner and is swingable up and down by rotation of the support member around its axis; an elastic member that rotates in a direction to swing the door roller downward;
an upper stopper member that regulates the rotation of the support member in the opposite direction of its axis to regulate the upward swinging position of the door roller, thereby adjusting the installation of the support member; interlockingly connected to the support member; and a guide member that engages from below with a downward guide groove of the lower frame of the frame in which the shoji is erected when the support member is erected; to restrict the downward swinging position of the door roller, and when the support member is in the installed state, the guide member is
a lower stopper member that prevents the member from escaping from the guide groove;
It has the following features.

Hereinafter, the present invention will be explained in detail based on drawings showing embodiments.

In FIG. 4 and FIG. 5, 21 is a door wheel, and the door wheel 21 is rotatably supported by a U-shaped support member 22, and this support member 22 is positioned downward near the U-shaped bent portion. is pivotally mounted within the frame 24 of the opening 23;
Door wheel 21 partially protruding from opening 23 of frame 24
It is designed to be able to freely swing up and down about an axis 25 in order to freely change the up and down position. In other words, the axis 2
5 is shifted from the axis of the door roller 21, and the support member 22
The door wheel 21 is made to be able to swing vertically by rotation around the axis. The support member 22 is constantly urged downward by the resilient member 26. That is, the resilient member 26 resiliently biases the support member 22 in one direction (to the left in the illustrated example), rotates the support member 22 around its axis in the forward direction, and swings the door wheel 21 downward. It is something that makes you Note that the forward rotation of the axis means counterclockwise rotation in FIG. 1. Reference numeral 27 is a brush that comes into contact with the running surface 29 of the lower frame 28 to remove dust, etc., and a hollow main body 30 is provided with a pair of projecting pieces 3 that protrude from the lower part of the outer side end 31 of the frame 24.
It is attached by being inserted and locked into 2 and 32. Reference numeral 33 denotes an upper stopper member consisting of a screw 34 that is screwed into the upper part of the outer side end 31 of the frame 24, and the tip of the screw 34 comes into contact with the outer side end surface 35 of the support member 22. Support member 2
The door roller 2
The upward swinging position of the shoji 36 is restricted and the screw 34 is screwed to adjust the installation of the shoji 36 relative to the frame. That is, the upper stopper member 33 is used for adjusting the installation. Note that the rotation in the opposite direction of the axis is clockwise in FIG. 1. Reference numeral 37 denotes a lower stopper member, which is composed of a screw 39 that is screwed into a plate nut 38 fixed between the protrusions 32, 32.
9 is inserted through the hollow part of the main body 30 of the brush 27 and screwed into the plate nut 38, and the tip is brought into contact with the lower end of the side outer end surface 35 of the support member 22, so that the axial center of the support member 22 is The downward swinging position of the door roller 21 is controlled by regulating the rotation of the door roller 21. That is, the upper stopper member 33 and the lower stopper member 37 are intended to prevent the support member 22 from vertically swinging. Reference numeral 40 denotes a guide member that engages with a downward guide groove (not shown) of the lower frame 28, and is interlocked and connected to the support member 22 within the frame 24, and its operation is similar to that of the guide member 12 described above. Since there is, I will omit the explanation. Further, the vertical position of the door roller 21 during installation and installation adjustment of the shoji 36 is also the same as that shown in FIG. 1, and a description thereof will be omitted. Then, when the support member 22 is in the installed state, the guide member 40 is set so as not to escape from the guide groove.

Thus, the frame 24 of the door roller device configured as described above is installed inside the lower stile 41 of the shoji 36, the shoji 36 is built into the frame 42, and the upper stopper member 33 is installed.
Installation adjustments will be made at. FIG. 4 shows the state after this installation adjustment, in which the support member 22 is prevented from vertically swinging by the vertical stopper members 33 and 37. Of course, before construction, the screws 34 and 39, which are the upper and lower stopper members 33 and 37, are attached to the support member 22.
The support member 22 is spaced apart from the side outer end surface 35 of the support member 22.
oscillation is not prevented. This screw 34, 39
For screwing forward and backward operations, use the through hole 44 at the bottom of the vertical stile 43,
This is done by inserting an operating tool such as a screwdriver (not shown) from 45.

In this way, after the installation adjustment by the upper stopper member 33, the support member 22 is adjusted by the lower stopper member 37.
If the downward swinging is also prevented, even if the door roller 21 rises from the running surface 29 of the lower frame 28 in the case shown in FIG. 3, the guide member 40 will not come off the guide groove of the lower frame 28. Therefore, it is possible to reliably prevent the shoji 36 from coming off unexpectedly. Then, if you want to remove the shoji 36, the through hole 4 of the vertical stile 43
Insert the screwdriver from 5 to lower stopper member 37
The screw 39 is unscrewed, and the support member 22
If it is allowed to swing downward, it can be removed normally. Note that in the embodiment, both the screws 34 and 39 are brought into contact with the outer side end surface 35 of the support member 22 to prevent the support member 22 from swinging at all.
The screw 39 which is the lower stopper member 37 is attached to the support member 2.
Therefore, it is not necessary for the support member 22 to be completely prevented from swinging between the ends of the screws 34 and 39.

FIG. 6 shows another embodiment of the lower stopper member 37, in which notch holes 46, 46 are formed in the left and right frames of the U-shaped support member 22, and a pressing plate 47 spanning the notch holes 46, 46 and a frame The tip of a screw 48 that is screwed onto the outer side end 31 of the body 24 and inserted through a through hole formed on the outer side end surface 35 of the support member 22 is loosely connected to the lower stopper. By screwing back the screw 48 which is the member 37, the pressing plate 47
The support member 22 can be pressed against the tip of the screw 34, which is the upper stopper member 33, and its swinging can be prevented. In this case as well, it goes without saying that the downward swinging of the support member 22 may be prevented within the swinging range that can be adjusted during installation. In this embodiment, the vertical stopper member 3
3 and 37 can be located close to each other, one hole can serve as the through holes 44 and 45 for inserting the operating tool provided in the vertical stile 43 shown in FIG.

FIG. 7 shows still another embodiment of the lower stopper member 37, in which a slide member 49 is inserted and held in the hollow part of the main body 30 of the brush 27, and the slide member 49 is always attached upward by a leaf spring 50. It has a stepped portion 53 which is always urged outward by a compression spring 51 and engages with the protrusion 52 of the main body portion 30 by the elastic force of the leaf spring 50 in the pressed state. In this pushed state, the downward swinging position of the support member 22 is restricted by the distal end 54, and when the proximal end 55 is pushed down, the engagement between the protrusion 52 and the stepped portion 53 is disengaged, and the elastic force of the compression spring 51 causes the support member 22 to retreat. . Such pushing and pushing down operations of the base end portion 55 are performed through a through hole at the bottom of the stile (not shown). The operation is done automatically by simply touching the shoji to the vertical frame of the frame.

FIG. 8 shows a modified example of the resilient member 26. In this case, the resilient member 26 has a screw 34 inserted therethrough, and similarly to the above-mentioned embodiment, the resilient member 26 resiliently moves the support member 22 in one direction (that is, to the left). The support member 22 is energized and rotated around its axis in the forward direction, thereby swinging the door wheel 21 downward. Note that in this case, the guide member 4
0 is of course provided, but is not shown.

The present invention has effectively achieved its intended purpose with the configuration detailed above. That is, the guide member 40 is connected to the resilient member 26.
Since the guide member 40 is always swung downward by the slider, the guide member 40 can be easily engaged with the guide groove, and the shoji 36 to which the door roller device is attached can be easily and quickly built into the frame 42. I can do it. Furthermore, after the shoji 36 is erected and the upper stopper member 33 adjusts the erecting of the support member 22, the lower stopper member 37 restricts the downward swing of the support member 22, so that the shoji 36 is erected. Even if the lower frame 28 and upper frame of the frame 42 bend, the shoji 36 shakes, and the door roller 21 lifts off the lower frame 28 running surface 29,
The guide member 40 interlocking with the support member 22 does not escape from the guide groove, and the shoji 36 does not come off from the frame 42.
