Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a hanging wheel for slidingly hanging the upper edge of a folding door or other door.

[Conventional technology]

A hanging wheel for slidingly hanging a door on a rail has a slider with wheels on the rail side and a mounting seat on the door side that are detachable, making it easy to hang and remove the door.

As shown in Fig. 5, the prior art of this removable hanging wheel consists of a slider 3 with wheels 2 that runs within the rail 1 of the upper stile, and a seat 5 fixed to the upper edge of the door 4 via screws or the like. First, the disc 7 provided at the lower end of the protruding shaft 6 protruding downward from the lower surface of the slider 3 is inserted into the seat 5 through the end face opening of the groove-shaped seat 5, which is open between both edges of the upper surface. The door 4 is suspended by coupling the slider 3 and the seat 5.

Next, while inserting the plate-like body 8 into the end opening of the seat 5, press the bullet piece 9, which is connected from the end of the plate-like body 8 and folded back to the upper surface, against the upper surface of the plate-like body 8. Insert the tips of 9 together,
When the notches 10 on both sides of the upper surface of the seat 5 and the protrusions 11 on the top surface of the tip of the bullet piece 9 match, the pressing of the bullet piece 9 is released and the engagement between the notch 10 and the protrusion 11 causes the plate-like shape to be removed from the seat 5. Make sure that the body 8 does not fall off.

In addition, the above-mentioned plate-shaped body 8 is adapted to be fitted into both ends of the seat 5, respectively, in the illustrated case.

[The problem that the idea attempts to solve]

Because the plate is inserted and removed in a narrow space between the rail and the upper edge of the door, work efficiency is poor, especially when inserting the plate while pushing down the bullet piece, or pushing down on the bullet so that the protrusion escapes from the notch. The problem was that the operation was even more complicated because the plate-like body had to be removed by hand.

This invention was made in view of the above-mentioned problems, and the purpose is to provide a hanging wheel that can be attached and detached extremely easily.

[Means to solve the problem]

In order to solve the above problems, this invention has a slider that is composed of a base material with wheels that fits into the rail, and a head provided at the lower end of a shaft member that protrudes downward from the bottom surface of this base material. a box attached to the upper edge of the door; a through hole formed in the top wall of the box so that the head of the slider passes through; a moving plate built into the box with a return force applied in one direction;
A lock device is provided to automatically stop the returning movement of the moving plate when the moving plate is moved in the other direction, and to release the stop by contact with the head passed through the hole. The seat is composed of a notch into which the shaft is fitted when the movable plate returns, and an operating piece that protrudes outside the box to move the movable plate in the other direction. .

[Effect]

The operating piece moves the movable plate in the other direction, and the locking device locks the movable plate to prevent it from returning to one direction.

Next, when the head of the slider and the shaft are passed through the through hole of the box while lifting the door, the locking device is unlocked by the contact of the head, so the movable plate moves back and the shaft The notch of the moving plate fits into the material.

Therefore, the slider and seat are combined to hang the door.

When removing the door, move the movable plate in the other direction using the operating piece, and the notch will come off the shaft, so lower the door and remove it.

〔Example〕

In the figure, reference numerals 21 include a base material 22 that fits into the rail A, wheels 23 supported on both sides of the base material 22, and a wheel 23 that protrudes downward from the center of the lower surface of the base material 22 and has a lower end. This slider is composed of a shaft member 24 located at a position lower than the bottom surface of the rail A, and a head portion 25 provided at the lower end of this shaft member 24.

26 is a slider 21 attached to the upper edge surface of the door 27.
It is a seat that can be attached and detached at will.

The seat 26 has a box 28 attached to the upper edge of the door 27 with screws, and a box 28 that is attached to the upper edge of the door 27 with screws.
A through hole 29 is formed in the top wall of the box 28 so that the head 25 passes through it, a movable plate 30 is built into the box 28 with a return force applied in one direction, and an operating piece 31 that protrudes outside the box 28 is operated. A locking device 32 is provided to stop the return movement of the moving plate 30 when the movable plate 30 is moved in the other direction by the locking mechanism, and to release the stop by contact with the head 25 passed through the through hole 29. , and a notch 33 provided in the movable plate 30 so that the shaft member 24 fits into the movable plate 30 when the movable plate 30 returns.

A method for hanging and removing the door 27 using the slider 21 and seat 26 configured as described above will be explained.

First, move the plate 3 in the other direction by operating the operating piece 31.
Push 0 back.

At this time, the locking device 32 automatically locks the movable plate 30 to prevent its return movement.

Next, when the door 27 is lifted and the head 25 is aligned with the through hole 29, and the head 25 and shaft member 24 are passed through the through hole 29, the locking device 32 is locked by the contact of the head 25 that has passed through. is removed and the movable plate 30 moves back, so a notch 33 is formed in the shaft member 24.
gets stuck.

Therefore, if the edge of the notch 33 is caught on the peripheral edge of the back surface of the head 25, the head 25 is prevented from coming off together with the shaft member 24 from the box 28, and the door 27
hang it up.

Furthermore, when removing the door 27, when the moving plate 30 is pushed back and locked by the locking device 32, the engagement between the notch 33 and the head 25 is released.
The shaft member 24 and head 25 are removed from the box 28 and the door 27 is lowered.

Note that the movable plate 30 may adopt a rotating type instead of the illustrated sliding type.

In addition, although the notch 33 is formed by cutting out the periphery of the through hole 34 of the head 25 provided in the movable plate 30 in the illustrated case, it may be formed by notching the periphery of the movable plate 30.

Furthermore, the locking device 32 fixes an inverted L-shaped bent piece 36 at the tip of a leaf spring 35 parallel to the movable plate 30 to the back surface of the top wall of the box 28, as shown in FIG.
When the movable plate 30 is pushed back, the protrusion 3 of the movable plate 30
7 rides over the protrusion 38 on the upper surface of the tip of the leaf spring 35, and the return of the movable plate 30 is prevented by the engagement between the protrusion 38 and the protrusion 37, and the end of the leaf spring 35 is prevented by the head 25. Although the protrusion 38 and the protrusion piece 37 are disengaged from each other when the protrusion 38 is pushed down, they may be locked by other configurations.

In addition, as shown in the figure, a disk 3 is attached to the lower end of the shaft member 24.
9 is provided and this disk 39 is fitted into the through hole 34, horizontal movement of the head 25 can be stopped.

In the figure, 40 is a spring for returning the movable plate 30, and 41
is a penetrating window of the operation piece 31.

〔effect〕

As mentioned above, according to the hanging wheel according to this invention,
By passing the head of the slider and the shaft member through the through hole in the top wall of the box of the seat, the lock of the locking device is automatically released and the movable plate is moved back, and the notch of the above-mentioned movable plate is inserted into the shaft member. Since the slider and the seat are connected by fitting, the door can be hung easily, and there is no need to insert a finger into the narrow space between the rail and the upper edge of the door to perform the connection operation.
