Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a door roller device that is attached to the lower stile of a traveling fitting.

Conventional technology An inner frame equipped with rollers is fitted into an outer frame so as to be movable up and down, and a pair of diagonal grooves are formed on the outer frame, and protrusions that fit into the grooves are formed on the inner frame. The frame can be moved diagonally up and down along the groove via the protrusion, and the adjustment screw screwed into the outer frame contacts the inner frame and the adjustment screw is screwed in to push the inner frame and move it diagonally up and down. A door roller device is known in which the roller can be moved up and down with respect to the outer frame, and the installation of traveling fittings can be adjusted.

Problems to be Solved by the Invention After the door roller device is assembled by fitting the inner frame into the outer frame, the inner frame cannot be easily removed from the outer frame, and the outer frame is attached to the lower stile of the traveling fitting. The inner frame cannot be removed from the outer frame.

For this reason, if the rollers become worn, it is necessary to remove them from the lower stile with the outer frame and inner frame assembled, but normally the door roller device is installed by inserting it into the hollow part of the lower stile from one longitudinal end. Therefore, in order to remove the door wheel device, it is necessary to disassemble the lower stile and the vertical stile, which makes replacing the rollers of the door wheel device extremely troublesome.

Means and operation for solving the problem: An inner frame having a roller is mounted inside the approximately U-shaped outer frame so as to be movable diagonally up and down, and an adjustment screw is screwed into the outer frame to attach it to the inner frame. A stopper that comes into contact with the outer frame and restricts the downward movement of the inner frame is attached so as to be movable between a restricting state and a non-restricting state, so that the inner frame can be taken out downward from inside the outer frame. This is what I did.

Embodiment The outer frame 1 consists of an outer frame body 2 and a fixer 3,
The outer frame main body 2 has a downward U-shaped cross section with a narrow width including an upper plate 4, side plates 5, 5, and one end plate 6.
The fixer 3 is fitted and fixed to one end of the outer frame main body 2, and has a crimp fin piece 7 integrally formed at its lower part, and a protrusion 8 integrally formed at the other end. This protruding portion 8 is narrower than the fixer 3 and has a hole 9 formed therein, through which a bottle 10 fitted and supported between the side plates 5 and 5 is inserted into the guide member. At the same time,
A guide member, for example, an oblique protrusion 11, is formed inwardly at the upper part of one end side of both side plates 5, 5, and the one end plate 6 is bent into an L shape, and a horizontal bent piece thereof is formed. A stopper 12 is attached to the portion 6a so as to be movable left and right with a screw 13 inserted through a long hole 12a, and the stopper 12 is parallel to the upper plate 4 and projects into the outer frame body 2.

The inner frame 20 has an elongated U-shape in which side plates 21, 21 are connected by a horizontal plate 22, and is inserted into the outer frame main body 2 from below, and the protruding portion 8 is connected to the side plates 21, 2 by a horizontal plate 22.
1, and there are bottles 10 on both side plates 21, 21.
A diagonal notch groove 23 is formed through which the
This notched groove 23 is parallel to the punched-out projection 11, and is open to the other end surface 21a of both side plates 21, 21, and has an inclined surface in contact with the punched-out projection 11 at the upper part of one end side of both side plates 21, 21. A guide surface 24 is formed so that the inner frame 20 can move diagonally up and down with respect to the outer frame 1, and an adjustment screw 27 that is screwed into a screw hole 26 of a plate 25 provided in the fixer 3 is attached to the horizontal plate 22. A roller 28 is supported by a shaft 29 within the inner frame 20, and a contact portion 30 facing the stopper 12 is integrally formed at the other end of the both side plates 21.

Since this is the case, loosen the screw 13 and move the stopper 12 along the long hole 12a to remove the contact portion 3.
0, the inner frame 20 is located at a position that does not interfere with the bin 1.
It can be rotated downwards around 0, and the bin 1
Since the notch groove 23 into which 0 was inserted opens at the end surfaces 21a of the side plates 21, 21, the inner frame 20 can be removed from the outer frame 1 by rotating downward as shown by the arrow, and the above-mentioned By performing the opposite operation, the inner frame 1 can be attached to the outer frame 1.

Therefore, as shown in FIGS. 4 and 5, one end in the longitudinal direction is located in a hollow portion 44 consisting of both vertical plates 41, 41, an upper horizontal plate 42, and a lower horizontal plate 43 of the lower stile 40. When inserted and installed, lower horizontal plate 43
The inner frame 20 can be removed through the opening 45 formed in the inner frame 20.

As shown in FIG. 6, the opening 45 of the lower horizontal plate 43 has a dimension S ₁ equal to the wall thickness of both side plates 5 of the outer frame body 2.
, and the crimping fin piece 7 is crimped to the remaining portion 43a, and
A notch 46 is formed at the longitudinal end of the remaining portion 43a, and a stopper piece 3a integrally formed at the lower part of the fixer 3 comes into contact with this notch 46 for longitudinal positioning. be.

From FIG. 7 onwards, a second embodiment is shown, in which a punched-out projection 31 that fits into the notch groove 23 formed on both side plates 21, 21 of the inner frame 20 is formed on the upper part of one end side of the side plates 5, 5 of the outer frame 2. At the same time, the guide piece 3 is attached to the horizontal plate 22.
2 is fixed with a pin 33, a crimping tongue piece 34 is integrally formed continuously with the upper plate 4, and one end plate 6 of the outer frame main body 2 is pressed diagonally downward along the protrusions 11 and 31 by hammering out the inner frame 20. It can be repeatedly displaced between a substantially vertical position in which the contact part 30 interferes when the contact part 30 moves and an upwardly inclined position in which it is tilted upward so as not to interfere with the contact part 30. Note that the fixer 3 is fixed to the outer frame body 2 with a pin 35.

In this way, as shown in FIGS. 10 and 11, when the one end plate 6 is tilted upward while being slid and inserted into the hollow part 44 of the lower stile 40 and attached, the inner frame can be fixed. 20 can be removed.

In other words, one end plate 6 becomes a stopper.

Effects of the invention By moving the stopper to the unrestricted state, the inner frame 20 can be removed downward from the inside of the outer frame 1, so the inner frame 20 can be removed together with the rollers 28 while still attached to the lower stile, and the rollers 28 can be removed. Replacement work becomes easy.

If you move the stopper to the state that restricts the stopper, the inner frame 20 will not fall off from the outer frame 1 by mistake when carrying it, and when removing the moving fittings from the window frame etc. while attached to the lower stile, the inner frame will not fall off. 20 will not fall off.

By operating the adjusting screw 27 and moving the inner frame 20, the vertical height of the roller 28 relative to the outer frame 1 can be adjusted, so that the installation of the traveling fittings can be adjusted.
