Description

[Detailed Description of the Invention] The present invention relates to a hanging door support device that suspends the upper part of the door in a slidable manner.

Conventionally, this type of hanging door is suspended so that it can be opened and closed by engaging several door rollers with the upper end of the door attached to the upper side of an upper rail attached to the ceiling wall etc. of the door mounting part. According to this conventional structure, the weight of the door is always acting on the door roller, which causes severe mechanical fatigue and wear on the rotating shaft and bearing of the door roller, resulting in poor durability. As it wears down, it becomes difficult to open and close smoothly, and it also generates a lot of noise.

In view of the above points, the present invention provides support for hanging doors that is highly durable with less mechanical fatigue and wear on the door support part, and that does not interfere with the smooth opening and closing of the door or generate noise. The purpose is to obtain a device whose configuration is as follows.

In this invention, the suspension is attached to the upper fixed wall of the door mounting part in a horizontal position via a mounting frame equipped with a suspension horizontal level adjustment mechanism, and by attaching the upper end of the door to this suspension, the door can be suspended so that it can slide open and close. The above-mentioned suspension has a sliding frame having a shape corresponding to the iron frame within a fixed frame having a U-shaped cross section, and a plurality of balls movably interposed between the upper and lower ends of each other. The sliding frame is attached to the upper end of the door, and the fixed frame is attached to the mounting frame, with the center of each ball of the suspension aligned on the same vertical line as the center of gravity of the door. This is a support device for a hanging door.

Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, A is a section for installing a hanging door;
A1 is an opening that is opened and closed by a hanging door, B is a hanging door,
C is a suspension that allows the door B to be slidably suspended;
D is a mounting frame for attaching the suspension C to the upper fixed wall, and E is a steady rest mechanism at the bottom of the door.

The main body of the hanging door support device according to the present invention is composed of a suspension C and a mounting frame.

The mounting frame is separated from the wall fixing member 1, the intermediate member 2, and the suspension fixing member 3.

The wall fixing member 1 has an angular shape and has a door mounting section A.
It is fixed to the upper fixed wall with anchor bolts or the like, and bolt insertion holes 4, 4 are provided on the left and right sides of the horizontal side projecting forward from the wall surface.

The intermediate member 2 has a cross-sectional shape, is fixed to the lower surface of the wall fixing member 1, and is provided with screw holes 5 at several places in the left and right direction on its vertical side.

On the other hand, the suspension fixing member 3 has a generally U-shaped cross section, and has the bolt insertion holes 4, 4 in the left and right sides of the upper side.
Bolt insertion holes 6, 6 corresponding to the holes 4, 4 and 6 are provided.
, 6, insert bolt 7.7, and align with bolt 7.7)
8a, 8a and 8b, 8b, attach the suspension fixing member 3 to the wall fixing member 1, and attach the suspension fixing member 3 to the wall fixing member 1.
The fixing member 3 can be horizontally adjusted by adjusting screws a, 8b, and sb.

In other words, the structure constitutes a horizontal level adjustment mechanism for holding the suspension C in a horizontal position.

Further, screw insertion holes 9 corresponding to the screw holes 5 of the intermediate member 2 are provided on the vertical sides of the suspension fixing member 3.
. . . is provided, and the screw 1 is inserted through the hole 9 .
0... is screwed into the screw hole 5...

The screw insertion holes 9 are elongated vertically so as not to interfere with the function of the horizontal level adjustment mechanism.

In this way, by connecting the vertical sides of the suspension fixing member 3 to the intermediate member 2, which is the fixing part, it is possible to prevent the member 3 from swinging back and forth, that is, swinging the hanging door B back and forth. ing.

Next, suspension C will be explained.

As shown in FIGS. 3 and 5, this suspension C includes a fixed frame 11 formed in the shape of a long frame with a U-shaped cross section and curved upper and lower sides in an arc shape, and a fixed frame 11 that is higher than the fixed frame 11. A sliding frame 12 with a low U-shaped cross section whose upper and lower sides can be bent inward, and a plurality of balls 13...
By fitting the sliding frame 12 into the fixed frame 11 with balls 13 interposed between the upper and lower sides of each other, the sliding frame 12 can be lengthened. It is configured to be able to slide along the horizontal direction.

14 is a retainer. When using this suspension C, when the sliding frame 12 slides, the balls 13...
While rolling in the sliding direction along the fixed frame 1, the balls 13... contact the sliding frame 12, which is sliding at a faster speed, so that the fixed frame 11 and the sliding frame 1
2 becomes extremely small, and therefore the sliding frame 12 can be slid very easily.

Also, as the sliding frame 12 slides, the contact points between the steel frame 12 and the balls 13... and the balls 13...
... and the fixed frame 11 move, the hanging load applied to the sliding frame 12 does not act intensively on a specific portion.

In other words, there is no part that constantly carries the hanging load in a concentrated manner, such as the rotating shaft and its bearing in the case of a door roller, so there is less mechanical fatigue and wear on the material.

Although the number of balls 13 can be selected as appropriate, the more balls there are, the more the load will be distributed, so that the sliding frame 12 can be slid more easily, and fatigue and wear of each part can be further reduced.

Further, in this embodiment, reinforcing frames 15 and 16 formed by extrusion of aluminum and having a U-shaped cross section are fitted and fixed on the outer surface of the fixed frame 11 and the inner surface of the sliding frame 12, respectively.

Both fixed and sliding frames 11 and 1 are fixed by this reinforcing frame 15 and 16.
2 can be reinforced, and even if door B is quite heavy, both frames 11
, 12 are not bent and can be used satisfactorily.

Furthermore, depending on the required stroke of the door, suspension C
When the fixed and sliding frames 11 and 12 are each composed of a plurality of unit frames each having a fixed length, each of the reinforcing frames 15 and 16 is formed into a single long piece so that the length can be selected. However, if each unit frame is attached to this, there is a practical benefit such that both reinforcing frames 15 and 16 also serve as a connecting body for each unit frame.

To attach this suspension C to the above-mentioned mounting frame, the fixing frame 11 and the reinforcement frame 15 of the suspension C are placed on the lower side of the suspension fixing member 3, and both frames 11 and 15 are assembled together. It is attached to the fixing member 3 by screws 17.

To attach the door B to the suspension C, the hanging frame 18 is fixed to the sliding frame 12 by welding or the like, and the lower end of the hanging frame 18 is attached to the upper end surface of the door B by two sets of bolts 19.
, by connecting them with nuts 20.

In this case, balls 13 in suspension C...
... and the center of gravity of door B are connected on the same vertical line.

In the case of the door B shown in the figure, it has a symmetrical structure and its center of gravity is located at the center in the front and back direction, so the center line in the front and back direction of this door B is located at the center of the ball 13 as shown by the dashed line in FIG. 3. It is aligned with the center of the

In addition, in order to obtain such a mounting condition, the hanging frame 18 has a cross-sectional shape as shown in the figure, and the bolt insertion holes 21, 21 provided at the lower ends of both frames 18 are made thicker than the bolt diameter. is forming.

Alternatively, the hole 21 may be an elongated hole that is long in the front-rear direction, or a notched hole that opens forward.

In this way, ball 13 of suspension C...
By aligning the center of ・ and the center of gravity of door B on the same vertical line, the weight of door B is always placed in the vertical direction at the contact point between ball 13... and sliding frame 12 and fixed frame 11. As a result, a swinging moment in the longitudinal direction is applied to the contact point, and the sliding frame 12 and the fixed frame 1
1 from being bent and deformed.

As mentioned above, the suspension C is attached to the mounting frame attached to the upper fixed wall of the door mounting section A, and the door B is suspended from the suspension C, thereby supporting the iron PB so that it can slide left and right. It's forcing me.

When actually assembling, attach the mounting frame and suspension C to the wall side in advance as shown above.
You may take the procedure of attaching the door B to the hanging frame 18 vertically installed on the suspension C, or you may attach only the integral part of the wall fixing member 1 and the intermediate member 2 of the mounting frame to the wall side, and attach other members. are all attached to the door B side, and the suspension fixing member 3 on the door side is attached to the wall fixing member 1 as described above.
Alternatively, a procedure may be adopted in which the intermediate member 2 is connected to the intermediate member 2.

Regardless of which assembly procedure is used, it is important to maintain suspension C in a horizontal position using the suspension horizontal level adjustment mechanism on the mounting frame, and to align the center of the ball of suspension C with the center of gravity of door B on the same vertical line. Needless to say.

In addition, after assembling the door, considering the appearance, the above-mentioned structural part of the upper part of the door is attached to the cover 2 as shown by the phantom line in Figure 3.
It is desirable to conceal it in step 2.

Next, the steady rest mechanism E at the bottom of the door will be explained.

As shown in Fig. 1, the door B has a larger width than the opening A1, and when the door is closed, it touches the floor F where the right end of the door B and the left wall of the opening A1 overlap. A steady rest mechanism E is provided at the bottom of the door.

That is, as shown in FIGS. 6 and 7, a roller seat 23 having a frame shape with a U-shaped cross section is attached to the floor F along the width direction of the door B with anchor bolts 24 and nuts 25, and the roller seat 23 Vertical axis 26 on the upper surface of both sides in the length direction.
．． Horizontal rollers 27, 27 are rotatably attached via 26, and both rollers 27, 27 are engaged with a groove 28 formed on the lower end surface of the door B over the entire length in the width direction.

At this time, the concave groove 28 is formed to be slightly wider than the diameter of the roller 27.27, and the roller 27.27 is configured to engage with the inner surface of either the front or rear of the concave groove 28 in a freely rolling manner.

The groove 28 may be formed by opening the voice end face downward and attaching a frame 29 with a predetermined cross-sectional shape therein, as shown in the figure, or by forming the lower end face of the door B itself into a concave shape. It may also be formed by

By adopting such a configuration, the position of the lower end of the door B in the front-rear direction is regulated to be constant, thereby preventing the door B from swinging in the front-rear direction.

As described above, the mechanism for preventing the door B from swinging in the front-rear direction is constructed by fixing the vertical portion of the suspension fixing member 3 to the intermediate member 2 at the upper part of the door. The anti-sway mechanism at the top of the door reliably prevents the door B from swinging back and forth.

Therefore, no bending moment acts on the suspension C, and mechanical fatigue and wear of the suspension C can be further reduced.

In addition, in the case of the above-mentioned lower steady rest mechanism E, since it is installed only on the floor part that is hidden by the door B when the door B is open or closed, avoiding the floor surface of the opening A1 which is the entrance/exit, It does not obstruct the passage of wheelchairs, etc., and has a good appearance.

Further, the door B can be smoothly opened and closed by the rollers 27, 27, and the provision of this mechanism E does not cause any problems such as making the operation of opening and closing the door B difficult.

Therefore, when using this hanging door support device configured as described above, the door B can be easily slid open and closed due to the characteristics of the suspension C described above, and the suspension C has less mechanical fatigue and wear, resulting in durability. It is rich in

In addition, the ball center of the suspension C and the center of gravity of the door B are aligned on the same vertical line, and the door B is prevented from swinging back and forth by the anti-sway mechanism at the top of the door.
Because an unreasonable bending force acts on the suspension C due to these two points, mechanical fatigue and wear can be further suppressed and durability can be increased.

Therefore, when this device is used, it is possible to maintain the initial good function over a long period of time, and there is no risk that the opening/closing operation will gradually become difficult or that loud noises will be generated as in the case of the conventional door roller type.

Furthermore, the suspension C can be maintained in a horizontal position by the horizontal level adjustment mechanism provided in the mounting frame.
This prevents the door B from slipping, that is, from opening or closing naturally due to the suspension C being installed with an inclination in the left-right direction.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, the specific shape of the mounting frame may be modified as appropriate other than the above-mentioned embodiments, for example, it may be shaped into a panel, a portal frame, or a combination thereof. good.

On the other hand, the specific structure of the suspension horizontal level adjustment mechanism can also be selected as appropriate depending on the shape of the mounting frame, etc.

In addition, in the above embodiment, the door B is slid in front of the vertical wall surface, but the door B is arranged in an opening that is approximately twice the width of the door B, and is slid within the opening. It is also possible to close half of the area with a blind plate.

Furthermore, it goes without saying that the present invention can be applied not only to single-swinging doors but also to double-swinging doors.

As mentioned above, the present invention has a suspension for slidingly suspending the door, a sliding frame inside a fixed frame with a U-shaped cross section, and a plurality of balls that can be moved freely between the upper and lower ends of each other. With this suspension, the sliding frame can slide easily with less friction when sliding, and the axle and its bearing part in the case of a door roller can be easily slid. Since there are no parts that are constantly subjected to the load of the head of the household intensively, mechanical fatigue and wear of the suspension components are reduced.

In addition, since the door is suspended from the suspension with the center of the ball of the suspension and the center of gravity of the door aligned on the same vertical line, no bending force is applied to the suspension, and therefore the sliding frame or fixed frame It is possible to prevent bending deformation of the suspension, and further suppress mechanical fatigue of the suspension.

Therefore, according to the present invention, the door can be opened and closed easily, and the suspension has excellent durability, so that even after long-term use, the door does not interfere with the smooth opening and closing of the door or generates loud noise. This allows the initial light and quiet door opening/closing operation to be maintained.

Moreover, since the above-mentioned suspension is attached to the upper fixed wall of the door mounting part via a mounting frame, and a suspension horizontal level adjustment mechanism is provided in this mounting frame, this mechanism allows the suspension C to be reliably adjusted without the risk of tilting in the left-right direction. Can be installed in a horizontal position.

Therefore, even if the sliding resistance is small, such as the suspension of the present invention, there is no risk of the door opening or closing on the wrong side, so it has extremely high practical value.
