There is known a structure in which it is attached and fixed to the upper end by means such as screwing.

However, this type of conventional suspension vehicle such as a sliding door is in a suspended state, and a screw is used to smoothly open and close the sliding door etc. when the lowermost end of the sliding door etc. is slightly above the lower frame. It was necessary to attach and fix the other end of the metal fitting to a sliding door or the like while adjusting the position of the stopper or the like, which was a very troublesome installation work.

Even if it is installed and fixed in the best condition, it will not be able to open and close smoothly due to the weight of the sliding door, etc. due to the weight of the sliding door afterwards, and the mounting position of the metal fittings will be readjusted. It had problems such as having to do it.

<Purpose> The present invention solves the problems of the above-mentioned conventional suspension vehicles such as sliding doors, is easy to install on the door frame, and has been difficult to open and close smoothly due to its own weight due to its long-term use. Even in the case, it is an object of the present invention to provide a suspension vehicle such as a sliding door whose wheels can be vertically adjusted with the sliding door being built in the door frame.

<Structure> In order to achieve the above object, a suspension vehicle such as a sliding door with an up-down adjusting mechanism of the present invention has a holding frame with wheels mounted in a suspension vehicle case, and is orthogonal to the thickness direction of the suspension vehicle. It is a hanging vehicle such as a sliding door with a vertical adjustment mechanism that can adjust the wheels vertically by moving the holding frame by rotating the adjustment screw provided along the direction.

Therefore, it is preferable that the tooth pitches of both the rotating operation spur gear (7) and the rotation converting spur gear (5) are slightly larger with a margin.

Next, the vertical adjustment operation of the suspension vehicle such as the sliding door will be described.

First, in order to move the wheel (1) up and down, the adjuster (2) may be moved horizontally in the suspension car case (3). That is, the connecting pin (8) inserted into the slanted groove (20) of the adjuster (2) and the vertical groove (31) of the suspension car case (3) is inserted into the vertical groove (31) of the suspension car case (3). Since the movement in the horizontal direction is restricted, when the adjuster (2) moves horizontally, it moves along the slanted groove (20) of the adjuster (2), and the inclination of the slanted groove (20). Along with this, the connecting pin (8) moves up and down, and the holding frame (11) into which the connecting pin (8) is inserted and fixed moves up and down, and is rotatably attached and fixed to the holding frame (11). The moving wheel (1) will move up and down.

Then, in order to move the adjuster (2) horizontally, the adjusting screw (4) screwed into the screw hole (22) of the fixing pin (21) is rotated, whereby the adjusting screw (4) and the adjuster (2) are moved. ) Move the screwed position with.

Since the adjusting screw (4) is fixed to the suspension car case (3) as described above, the adjuster (2) is pulled toward or away from the adjusting screw (4), and thus the adjuster (2) is pulled. (2) moves horizontally.

Further, the rotation operation groove (71) of the rotation operation spur gear (7) exposed on the front surface or the back surface of the hanging vehicle case (3) is rotated to form the rotation operation spur gear (7). By rotating the meshing rotation converting spur gear (5), the adjustment screw (4) can be rotated.

Therefore, the wheel (1) moves up and down simply by rotating the rotating operation spur gear (7) from the front or back of the suspension case (3) by operating the rotating operation groove (71). Then
The vertical position of the wheel (1) can be freely adjusted.

It is also possible to directly rotate the groove (42) provided on the head side of the adjusting screw (4) to adjust the wheels up and down. The rotation operation from the front of the vehicle and the rotation operation from the side end of the suspension vehicle by the adjusting screw (4) can be selected.

Further, the present invention is not limited to the above-mentioned embodiment, and the storage recess (61) for storing the rotary operation spur gear (7) formed in the positioning frame (6) is provided on the front side or the back side. Only one of them may be formed so that the front and rear surfaces can be rotated, whereby the number of parts can be reduced.

Further, the rotation operation groove (71) formed in the rotation operation spur gear (7) is not limited to the cross shape as shown in FIG. 1, and may be a minus groove. Good.

Further, as long as it can be rotated from the outside, it may be an angular protrusion or the like that can be operated by turning a nut or the like instead of the groove.

Further, when it is not necessary to perform vertical adjustment in the longitudinal direction of the suspension car case (3), it is not necessary to form the insertion hole (34) in the side end surface of the suspension car case (3), and the collar portion (41) is not formed. It is sufficient to use a short adjusting screw, leaving a part of it and not on the head side. In this way, the number of parts can be reduced and the cost can be reduced.

Further, the worm gear (81) fitted and fixed to the operation shaft (82) is used as the rotation operation member, the worm wheel (80) is used as the rotation conversion member, and the worm wheel (80) is adjusted by the adjusting screw (4). ), The worm gear (81) is rotatably disposed on the inner surface side of the suspension car case (3) so as to be in an orthogonal meshing state with the worm wheel (80), The adjusting screw (4) may be formed so as to be rotatable by rotating the worm gear (81) (see FIGS. 6 and 7), or as shown in FIG. It is also possible to implement a combination of several bevel gears (90) and (91) (3 in the figure).

As a mechanism for moving the wheel up and down by turning the adjusting screw, a combination of the slanted groove (20) of the adjuster (2) and the vertical groove (31) of the suspension case (3) shown in FIG. 1 is used. In addition to the structure, the holding frame (11
0) is suspended by a rivet (100), etc.
It is also possible to implement a structure in which the wheel (1) is pivotally supported on the wheel and the holding frame (110) is turned by the adjusting screw (4) to move the wheel (1) up and down (see FIGS. 9 to 16). .

In addition to the horizontal mounting direction of the adjustment screw (4), the adjustment screw (4) is mounted vertically and the holding frame is moved up and down by the adjustment screw (4) (Fig. 14). Etc.)).

Various other design changes can be made without departing from the scope of the invention.

<Effects of the Invention> In the case of the suspension vehicle according to the present invention as described above, the holding frame to which the wheels are attached is mounted in the suspension vehicle case, and the adjustment screw turns provided along the direction orthogonal to the thickness direction of the suspension vehicle. By the motion
The wheel can be adjusted up and down by moving the holding frame, and the wheel itself is not directly movable by the adjusting screw, and the rotation is accompanied by the adjusting screw in terms of assembly structure. The conversion member and the rotating operation member that can be rotated from the outside of the suspension car case are housed in the positioning frame inside the suspension car case to provide a stable assembled state. Can be rotated by
The positioning frame part is capable of fulfilling the restriction that prevents the wheel from moving in the front-rear direction. The durability is improved by avoiding the direct load from the side. Then, the turning operation of the turning operation member is converted into the turning of the adjusting screw through the turning conversion member to move the holding frame of the wheel, thereby facilitating the vertical adjustment of the wheel. ing.

In addition, even if it hangs down due to its own weight due to opening and closing for many years, the wheels can be adjusted up and down just by rotating the rotating operation member with a driver or the like while it is still installed.

Therefore, since the operation part of the adjusting screw is on the side edge and the upper and lower end surfaces of the suspension vehicle as in the conventional case, it is difficult to perform the adjusting operation with the sliding door built, and it is necessary to remove the sliding door from the door frame and adjust it. The inconvenience of having to do the work can be eliminated. The vertical adjustment of the suspension vehicle can be done with the sliding doors still installed in the door frame, which makes it possible to perform extremely accurate adjustment work while observing the installation condition of the sliding doors, thus improving work efficiency. Various effects such as
