Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device (hereinafter referred to as a moving device) for suspending a partition wall panel (hereinafter referred to as a panel) on a traveling rail, moving it, and changing the direction.
The present invention also relates to technology for a fishing wheel mounted on a panel and a running rail that serves as a track to guide the running of the fishing wheel.

Conventionally, the running rail for a panel moving device has been a horizontally long hollow box with a horizontally long groove in the center of the bottom in which the lower bolt of the fishing wheel slides. It rides on the bottom of a running rail laid on the ground, and travels back and forth with rotating wheels, with a suspension bolt hanging freely from the center of the wheel axle (a panel is connected to this suspension bolt). be.

Conventionally, various new ideas have been made for the running rails and fishing wheels in panel moving devices, but there are still various problems left and new challenges to be solved.

One of them is the problem of the strength of the running rail and fishing wheel. Nowadays, in panel moving devices for public halls, hotel banquet halls, etc., panels weighing well over 100 kg are loaded onto a single running rail and moved repeatedly all the time. This has led to many cases of deformation of the running rail and damage to the wheels and axles of fishing carts.

The second problem is that running rails and fishing wheels now have very complex shapes.

For example, for complex shapes of running rails, the fact that we generally have to use extruded materials made of soft metals such as aluminum is related to the above-mentioned strength problem. This results in bias and distortion of the surface. As a result, the fishing wheel will run swaying on the running rail, and the weight of the panel will also be added, which can damage the fishing wheel itself, cause the wheel to slip on one side, or cause a collision between the wheel and the running rail. , or cause an accident. This is the reason why the running rail, which allows the fishing cart to travel back and forth without shaking, is stopped.

Next, it is not only necessary to move the panel along a single running rail, but in the case of partitions, in order to create enclosures and changes, the running rails are required to be orthogonal to each other or laid radially. There is a problem that fishing wheels are difficult to handle when the running rails are orthogonal or radial. In addition, in the case of partitions, in order to create a larger space by unraveling partitions that have been set up in parallel, there is a demand for changing the direction of the panels from the vertical direction (towards the running rail) to the horizontal direction, and accommodating the panels one after another in a stacked state. . As a device for this purpose, two running rails are laid in parallel, and a bent or orthogonal rail is crossed at the branching part of the two, so in addition to the difficulty of running the fishing wheel orthogonally, the two running rails are laid in parallel. There is a difficulty when the fishing wheels move separately on the running rails.
Changing the wheel of the fishing wheel at the junction point is commonly used, and on parallel rails it is especially necessary to change (sliding) the panel connection position of the fishing wheel. The improvements made to these issues are as follows: Special Publication No. 48-21247, Special Publication No.
No. 50-20496, Special Publication No. 60-7114, Special Publication No. 1987-
There are issues such as No. 7116.

However, in these conventional methods, the shape of the fishing wheel is complicated (for example, a large number of wheels of several types, such as a main wheel, a secondary guide wheel, and a horizontal wheel are used, each having its own wheel), and the shape of the fishing wheel is complicated. In some cases, the relationship cannot be said to be sufficiently close (for example, it is difficult to select the surface on the running rail of a fishing wheel that receives or does not receive the main wheel, or the surface that receives or does not receive the guide subwheel). .

Next, in order to adapt the fishing wheel to orthogonal running, curved running, or parallel running, a wheel device was developed in which a blind groove was provided on the upper end of the panel, and the lower fishing bolt was slidably moved through the groove (see the above-mentioned Japanese Patent Publication No. 48-21247). (No.), but the sliding response of the wheels was not considered to be good, especially when running in parallel.

The present invention solves the above-mentioned problems and problems by moving away from the conventional technology of fishing carts using wheels and running rails, which are frames that only guide the wheels, and by integrating them with the running shaft of a powerful track. This solution is achieved by combining a running rail formed on the shaft, a fishing wheel mainly consisting of a ball slide bearing fitted into the running shaft, and a hanging bolt that can be rotated freely around the fishing wheel. A distinctive feature is that they are used facing each other.

Hereinafter, embodiments of the present invention will be explained with reference to the drawings. The partition panel moving device of the present invention includes:
It consists of a running rail 1 and a fishing wheel 2 made of a hard material such as metal.
6.

The running rail 1 has a guide groove 7 formed by cutting out the lower central part of a hollow oblong member horizontally in an open state, and two rails protruding horizontally into the hollow portion from inner walls 8, 8 of the oblong member symmetrically to the guide groove 7. Providing shaft protrusions 9, 9,
A running shaft 10,1 having a circular cross section is provided at the tip of the shaft protrusion 9.
0 is provided in a horizontally long manner. In this case, in the longitudinal section of the horizontally long material cut into rings, the center line 11 of the shaft protrusion 9 passes through the center 12 of the running shaft 10, and the perpendicular line 13 hanging from the point of contact between the center lines 11 and 11 is the guide groove 7. It shall pass through the center point of.

Further, in the longitudinal cross section of the horizontally long material, one or two pairs of horizontally long shallow auxiliary grooves 14, 14 are symmetrically provided in the inner walls 8, 8, parallel to the guide groove 7, in the longitudinal section of the horizontally cut state. The above-described structure is referred to as a traveling rail 1.

The shape of the traveling rail 1 may be rectangular in the longitudinal section shown in FIG. 1, or may be circular, oval, or polygonal in longitudinal section.

The shaft protrusions 9, 9 may be provided parallel to the guide groove 7 as shown in FIG. 1, or may be provided obliquely, that is, at an acute angle or at an acute angle, with respect to the guide groove 7 in the cross section as shown in FIG. Good too.

The auxiliary groove 14 may be formed by notching the inner wall 8, or may be formed by a small protruding wall 15 as shown in FIG.

As shown in FIG. 2, the fishing wheel 2 has a running body 3.
It incorporates two slide bearings 4, 4, a suspension bolt 5, and an auxiliary wheel 6.

The traveling main body 3 has a small part 16 that is shaped to be fitted into the traveling rail 1, and its lower center is formed into a blind groove 17.
to form. The blind groove 17 opens in the lower surface of the small part 16 in a circular shape having a shape approximately equal to the outer diameter of the round bar of the lower bolt 5, and has a flat cylindrical hollow portion inside.

Further, in the small part 16, two horizontal holes 18, 18 with a circular cross section are provided, which are symmetrically located with respect to the center line 11 and pass through laterally above the blind groove 17. From horizontal hole 18
A horizontally long line is notched into the hole, and the opening is designated as a large C opening 20.

In addition, horizontal grooves 21, 21 are cut out horizontally in the small part 16 at positions facing the auxiliary grooves 14 of the traveling rail 1 on a surface perpendicular to the horizontal hole 18. The horizontal groove 21 is for fitting the auxiliary wheel 6 horizontally and snugly at both ends, and has a flat cylindrical shape in the illustrated embodiment, but may also have a flat rectangular cylindrical shape.

Depending on the shape of the traveling rail 1, the small parts 16 are
In the longitudinal section of the cross section, the cross section becomes rectangular, circular, or the like.

The slide bearing 4 is a ball slide bearing that is fitted into the horizontal hole 18 of the traveling main body 3, and has a cross section C.
The small C opening 22 of the opening part is fitted onto the shaft protrusion 9 of the traveling rail 1, and the bearing part 23
It has a size and shape that similarly circumscribes the traveling axis 10.

The lower bolt 5 is a round bar having a flat cylindrical locking portion 24 at its upper end, and is tightly fitted into the cap groove 17 with the locking portion 24 disposed with the bearing portion 23 below. The round rod is then locked to the locking inner wall 25 and hangs down from the circular opening.

The auxiliary wheel 6 is a bearing ring that rotates horizontally, and is fitted into the horizontal groove 21 as described above.

Now, the fishing wheel 2 is configured by internally fitting the locking part 24 with the bearing part 23 arranged below into the blind groove 17 of the traveling main body 3 (for internal fitting, it is preferable to use it separately as shown in the figure).
The hanging bolt 5 is made freely rotatable, and the slide bearings 4, 4 are inserted into the horizontal holes 18, 18 of the traveling body 3.
Insert the retaining rings 26, 26 into the outer ring oil grooves 27, 2.
7 and fixed therein, and the auxiliary wheels 6, 6 are fitted into the horizontal grooves 21, 21.

The partition panel moving device of the present invention, which incorporates a fishing wheel 2 into a traveling rail 1, can be seen in FIGS. 3 to 6. The installation procedure is as shown in FIG.
The running shaft 10 is tightly fitted to the outside so that it can reciprocate freely as a track, and at the same time, the small C opening 22 and the large C opening 20 are also tightly fitted to the shaft protrusions 9, 9, and the auxiliary wheels 6, 6 are rotatably fitted into the auxiliary groove 14. .

In this case, the longitudinal section of the sliced state (Fig. 3)
, the center line 11 of the suspension bolt 5 equally divides the line connecting the circular centers 12, 12 of the running shafts 10, 10, and is perpendicular thereto.

To use the present invention, the present invention is installed (fixed) in the upper part of the room where the partition is to be installed, and the lower end of the hanging bolt 5 is fixed to the center of the upper end surface 30 of the panel 29. Similarly, the existing hanging bolts 5, 5, etc. are connected and fixed to the required panels 29, 29, and moved and arranged in parallel to form a partition.

According to the present invention, the movement of the panel 29 uses two running axes 10, 10 as tracks and two slide bearings 4, 4, which are ball slide bearings that have a reputation for not causing sideways wobbling. As a result, a stable product with no shaking can be obtained. Furthermore, the gravity loads are balanced between the two slide bearings 4, 4 located at symmetrical positions. Traveling axis 1
Since the rails 0 and 10 are integrally formed within the running rail 1, there are no difficulties that arise when laying two rails in parallel. Since the fishing wheel 2 does not use wheels like conventional ones, accidents due to damage to the wheels do not occur, and the fishing wheel 2 does not have wheels, but has a huge track on the running shaft 10 of the traveling rail 1. Therefore, no breakdowns occur.

The direction of the panel 29 can be changed by using a hanging bolt 5 fixed to the panel 29 at the center of the upper end surface 30 of the panel 29.
and can be rotated freely within the bag groove 17 of the fishing wheel 2, so the direction of the panel 29 can be changed by the single traveling rail 1, whether diagonally or horizontally, for example. It is easy to accommodate the panels 29 in a stacked manner. Note that a circular stage 32 is provided at the branching part 31, and the traveling rails 1, 1, etc. are laid radially outside the circular stage 32 (Fig. 11), and the fishing wheel 2 is rotated at the stage 32, and the panel is moved in the desired direction. 29 can also be moved.

The auxiliary wheels 6 of the fishing wheel 2 are connected to the auxiliary groove 1 of the traveling rail 1.
4, and reinforces the reciprocating movement of the slide bearing 4.

The basic load rating of the slide bearing 4 is, for example, the shaft diameter
20 mm has a dynamic load rating of 135Kg and a static load rating of 125Kg, but in the present invention, by arranging two pieces symmetrically, the device has a higher strength than a single piece device.

The present invention is made smaller than the one described above, and as shown in FIGS. 9 and 10, a fishing wheel 33 using conventional wheels and a fishing bolt 5 according to the present invention are used.
It is also possible to attach the present invention along the upper end surface 30 of the panel 29 and use it as a sliding device in the panel 29 of the fishing wheel 33.
