Description

[Detailed description of the invention] (Field of industrial application) The present invention opens and closes a telescopic gate in the virtual straight direction connecting the gate post or hanging side support and the pull side support, and also This invention relates to a rotation restriction device for a telescopic gate in the cylindrical direction, which allows the telescopic gate to rotate in the cylindrical direction about the hinge axis.

(Prior art) When a conventional telescoping gate with a hinge is used in its current state, due to the influence of the rotation function in the cylindrical direction in the hinge part, when opening and closing in the imaginary straight direction connecting the gate pillars of the gate, the imaginary straight line It was difficult to operate the door if it deviated from the right direction, and in the case of gates that were opened and closed by riding the door roller on the rail, the door roller sometimes fell off the rail and caused trouble in returning to its original position. For this reason, an improved idea has emerged that guarantees linear stretchability by arbitrarily blocking the rotation of the hinge mechanism of the telescoping door body in the frontage opening/closing position to prevent it from rotating. Before this application, an example in which a telescoping door body was rotatably pivoted to a hanging side gatepost is shown in the first example.
For example, in the device disclosed in Utility Model Publication No. 55-180885, one of the inner and outer double cylinders fitted together so as to be relatively rotatable, one cylinder is placed at one end in the width direction of the opening. The double cylinder body is fixed in a vertical or nearly vertical position, and one end of the door of the other cylinder body is fixedly connected to the double cylinder body so that this door can swing open and close around the cylinder axis of the double cylinder body, and , the cylindrical member that can be fitted into and extracted from the double cylindrical body from above is placed in a first position in which the door is located within the opening, and swiveled at 90 degrees or approximately 90 degrees with respect to the opening. A notch is formed that allows the position to be fixed in the moved second posture, and
For example, in the second example, published in Utility Model Publication No. 58-29279, a hanging side gate post and a number of links are arranged tilting in opposite directions, and these links are used as pivot shafts. A telescoping door body is formed with a structure having vertical bars at least at both ends of a telescoping mechanism rotatably pivoted, and the top and bottom of one of the vertical bars in this telescoping door body are located on the hanging base side. A hinge mechanism that is attached to and supported by a gatepost;
A locking portion provided on the hanging side gate post and said one vertical beam apart from the hinge mechanism mounting side in the thickness direction of the telescoping door body, and a locking receiving portion from which this locking portion can be locked and detached. In addition, a device has been described which is equipped with a rotation prevention mechanism that holds the telescoping door body in the frontage opening/closing position by such engagement.

(Problems to be solved by the invention) Naturally, in the first example of the invention, the cylindrical member with the notch formed therein is dropped from above and fixed in such a way that it can be fitted and pulled out, so the cylindrical member cannot be attached or removed. Moreover, in the second example, the detent mechanism is complicated, and furthermore, when operating this detent mechanism, it is not on the hinge side, so it is inconvenient to operate the detent mechanism. There are problems such as the need for positioning the mechanism. The purpose of the present invention is to solve the problems of the above-mentioned conventional designs, to be extremely easy to operate, and to have a simple structure.
To provide a rotation regulating device for an extendable door body that is easy to install and maintain.

(Structure of the invention, means for solving problems) Hereinafter, the structure of the invention will be described with reference to embodiments of the invention shown in the drawings. In Fig. 3, 1 is a metal material such as aluminum alloy or mild steel, or an extruded material made of a strong synthetic resin material, cut into appropriate lengths,
The lower part of the gate is buried in the ground on the foundation surface G, fixed with concrete, etc., and the top is sealed. It is fixed at one end and has a height approximately equal to the height of a telescopic gate A described later, and is made of an extruded material similar to the gate post 1 described above, and a guide long groove 9 described later is provided on the inner surface of the frontage in the longitudinal direction. Hanging side support, 3
is a pull that is fixed to the side of the other gatepost 1 opposite to the one gatepost 1, or is fixed to the other end of the entrance opposite to the hanging side support 2, which is fixed to the side of the other gatepost 1 or independently fixed to one end of the entrance of a garage etc. A side support, A is a telescopic gate that can be opened and closed between the left and right gateposts 1 and/or the hanger side support 2 and the handle side support 3, and 6 is an extruded metal or synthetic resin material similar to the gatepost 1. The vertical bar 7 of the telescopic gate A made of shaped material etc. is the diagonal bar 7 of the telescopic gate A made of extruded shaped material or narrow width, thin thickness, long and short lengths, 7, etc. The diagonal beams are rotatably mounted or slidably attached to each other, and the diagonal beams are combined by crossing or butting each other. B1 and B2
is a thick single row made of a material similar to that of the vertical bar 6 that forms one end of the telescopic gate A to one of the gateposts 1, the hanging side support 2 fixed to the gatepost 1, or the single hanging side support 2. A double-row fixed vertical frame 4 is pivoted in the cylindrical direction of the opening of the fixed plate 12 around a pivot 13 (to be described later), and hinges are usually pivoted at two places, upper and lower, and 5 is a telescopic gate. A thick single or double-row movable vertical frame made of a material similar to the vertical frame 6 installed at the end opposite to the fixed vertical frame 4 of A, 8 is at the lower end of the movable vertical frame 5 and an appropriate vertical frame 6. This is a door wheel that rides on casters or rails that slide when moving the installed gate and always support the weight of the gate at the bottom. In Fig. 1a and Fig. 1b, 9 indicates the hanging side support 2 or gatepost 1 which is provided through the hanging side support 2 or the gatepost 1 along the frontage side inner surface thereof in its longitudinal direction. A sliding piece 19a of a stopper C, which will be described later, is slidably attached to the long guide groove, which is either integrally provided at the time of molding or is attached by fixing a separate extruded molded material using fixing means such as screws or welding. In addition, as for the stopper C mounted above the upper hinge B1 after mounting, a cap 20 is fixed to the top of the gate post 1 or the hanging support post 2 so that the stopper C cannot be easily removed. Note that the guide long groove 9 has a lip 19b running through both sides of the long groove, and the sliding piece 19a of the stopper C has a groove that engages with the lip 19b, so that the stopper C does not come off from the groove. In addition, if the stopper C is provided at the upper part of both the hinges B1 and B2, the strength of the rotation regulating device can be increased and damage can be prevented if the hinge is forcibly opened. 11
and 12 are fixing plates for the hinges on the side of the gate post 1 or hanging side support 2 and on the side of the telescopic gate A, respectively.The fixed plate 11 has a fixed plate sliding piece 11a joined to the back side fitted into the guide long groove 9, and the fixed plate 11 is attached to the hinge of the telescopic gate A. When opening in the cylindrical direction, even if the base surface G is a slope, the upper edge is made approximately horizontal so that the caster 8 etc. can always be grounded so that it can move up and down, and it is fixed by straddling the guide long groove 9 or fixed by a fixed plate. Fix it in place with 12 and the other screws. Reference numeral 13 denotes a pivot portion that rotatably supports the fixed plates 11 and 12 on a cylindrical surface on a horizontal plane, and connects them. As mentioned above, C is a stopper made of metal or strong synthetic resin that is slidably installed in the guide groove 9 on the upper edge of the upper edge of the hinge B2 and/or B1 of the gatepost 1 or the hanging support 2. Its longitudinal section forms a substantially T-shape. Reference numeral 14 corresponds to the leg of the T-shape and is a thin insert plate having a narrow width close to the width of the fixing plates 11 and 12 such as hinges B1 and B2, and 15 corresponds to the upper side of the T-shape and is slightly thick. It is a thick upper locking plate, and its both sides ride on the upper edges of the fixing plates 11 and 12 to form a mounting lower edge 15a that is equal to or slightly wider than the thickness of each of the fixing plates. Reference numeral 16 denotes a hanging piece that protrudes to the left and right and rides on the substantially parallel upper edges of the fixing plates 11 and 12, which are folded around the pivot portion 13 of the hinge B1 or B2 at one end of the upper locking plate 15. , 17a and 17b are approximately equal to the width of the lower mounting edge 15a and slightly wider than the thickness of the fixing plates 11 and 12, respectively, and are connected to the inside of the lower part of the left and right hanging pieces 16 and the left and right side surfaces of the upper part of the insertion plate 14. A groove serving as a locking portion H that holds the fixed plates 11 and 12 formed between them in a parallel state, 18 a tapered surface appropriately formed at the lower part of the hanging piece 16, and 19a a support on the suspension side of the locking upper plate 15. The sliding piece protrudes from the side facing the other side, and has lips 19b protruding on both sides thereof. In addition, the thickness of the side part of the hanging piece 16 is the same as that of the insertion plate 14 and the hanging piece 16 when the sliding piece 19a is fitted into the long guide groove 9 of the hanging base support 2, etc.
The outer end of the hinge is dimensioned so that it does not abut against the pivot portion 13 of the hinge B1 or B2. Next, Figure 2 a and Figure 2 b
The one shown in FIG. 2 illustrates two types of stoppers C that are different from the stopper C shown in FIGS. does not form a T-shape, and in the case of FIG. In this case, the inner surface of the hook piece 21 engages with the upper side and outer edge of the fixed plate 12, so that the hinge B1 or B2 is folded in a parallel state.
The opening rotation of the fixed plate 12 is restricted. Therefore, the width of the lower surface of the upper locking plate 15 inside the hook piece 21 needs to be slightly larger than the outer width of the upper edges of the fixed plates 11 and 12 in the parallel state, and
The fixing position of the fixed vertical frame 4 to the fixed plate 12 requires consideration to avoid the operating position of the hook or to provide a relief such as a notch in a part of the fixed vertical frame. Also, Figure 2b
1A and 1B, with the insert plate 14 cut away. Incidentally, except for the case shown in FIG. 2a, by increasing the thickness of the sliding piece 19a of the stopper C, the force applied to the hanging piece 16 on the fixed plate 11 side can be reduced.

(Function) The embodiment of the present invention is formed with the above-mentioned partial structure, and to explain its function, in the state shown in FIG. Then, the telescoping gate A changes the direction of the caster 8 from the current sideways orientation to a 90 degree angle and becomes forward facing (in the case of a door car riding on the rail, change the direction of the door car after getting off the rail). hinge B1 while sliding on its foundation surface G.
And the frontage distance of the telescopic gate A (the distance between the pivot portion 13 and the movable vertical frame 5 when the gate is folded from the state shown in FIG. 3 by the diagonal crosspiece 7) with the pivot portion 13 of B2 as the center is the radius. The feature of the hinge type is that the telescoping gate A is opened by rotating forward on a cylindrical surface. If you try to open a gate or garage entrance while folding the handle side column 3 toward the hanging column 2 along the imaginary straight line connecting the handle side column 3, the hinge part will not rotate unless a special hinge rotation restriction device is provided. Due to the rotation function in the mounting part, when the gate moves straight, a side-to-side rocking motion acts on the telescopic gate A, causing inconveniences such as deviating from the imaginary straight path or the door roller falling off the rail. was mentioned in the section of the prior art, but in the present invention, a stopper attached to the guide long groove 9 provided on the gate post 1 or the suspension side support 2 above the fixing position of the fixing plate 11 of the hinge B2 and/or B1 is used. C insertion plate 1
4 is the fixed plate 1 which is normally folded depending on its weight.
1 and 12 in a parallel state, and between the respective inner surfaces of the hanging pieces 16 on one side of the locking upper plate 15 and both outer surfaces of the insertion plate 14. 17a and 17b are fitted and locked to the upper edges of the fixed plates 11 and 12, so that the hinges B2 and/or B
1 is prevented from rotating around the pivot 13, and when the gate is operated, the telescoping gate A does not sway from side to side and can move smoothly on a virtual straight line or on a rail to open and close the gate. be. In that case, if the weight of the stopper C is appropriate, it is not necessarily necessary to provide the insertion plate 14 as shown in FIG. 2b, and the thickness of the sliding piece 19a is thick and has sufficient strength. In this case, the hanging piece 16 on the fixing plate 11 side is not necessary, and the entire longitudinal section does not have to be T-shaped, and the locking portion H is a hook piece provided on the lower surface of the locking upper plate 15 on the fixing plate 12 side. 2
1 may be engaged with the upper edge of the fixing plate 12 as appropriate.
Next, attach the telescopic gate A to the pivot portions 13 of the hinges B1 and B2.
Rotate in the cylindrical direction with the central axis to open it,
When closing the opened state and returning it to the above-mentioned imaginary straight line position or on the rail, lift the stopper C with the fingers of the first person and fix the fixing plates 11 and 12 or 1.
1 and then rotate the gate a little and release the fixing plate 12 from your finger at the point where it is away from the locking part H of the stopper C. The stopper C will move inside the guide long groove 9 under its own weight. It slides downward until it reaches the upper edge of the fixing piece 11 and is held in that position.
When the fixing plate 12 needs to be restrained again by the stopper C, the hanging piece 1 on the fixed vertical frame 4 side
6 or when the lower part of the outer surface of the hook piece 21 is a tapered surface 18, as the gate is rotated in the closing direction, the upper edge of the fixing plate 12 comes into contact with this tapered surface and pushes the stopper C upward. By raising the stopper C, the stopper C automatically straddles the parallel upper edges of the fixing plates 11 and 12, and the stopper C is placed between the concave grooves 17a and 17b or the lower surface of the locking upper plate 15 and the inside of the hook piece 21 or above the locking part. Rotation of the fixed plate 12 is prevented in a locked state by the lower surface of the plate 15 and the inside of the left and right hanging pieces 16.

(Effects of the invention) Since the rotation regulating device for a telescopic gate according to the invention has the above-described structure and function, it has the following specific effects.

(1) The length allows the sliding part of stopper C to fit into the long guide groove, making it easy to install and requires no adjustment.

(2) Since the stopper is slidable in the vertical direction, there is no problem with the operation of the stopper even if the fixing position of the fixed plate shifts, and the vertical movement of the gate is transmitted to the fixed plate through the fixed vertical frame during operation of the telescopic gate. Since the stopper can follow the movement by sliding up and down appropriately, there is no problem with the rotation regulation ability of the stopper.

(3) The operation of sliding the stopper upward to release the rotation restriction of the fixed plate can be easily performed from either the inside or outside of the gate at the hinge attachment part, so when the gate is in an extended state, other designs can be used. There is no need to go around to other places, which saves you a lot of effort.

(4) The rotation regulating device is mainly a stopper, and its installation is done by using a sliding piece to attach it to a long guide groove provided in the gate post or hanging support in the longitudinal direction. Since it can be easily installed on both the upper and lower hinges, it is possible to easily distribute the load on the lip of the long guide groove of the rotation restriction device and the locking part H, which is advantageous in terms of design and maintenance.
Additionally, durability can also be improved.

(5) When the lower part of the outside surface of the hanging piece 16 or hook piece 21 on the fixed plate 12 side of the hinge, that is, on the side of the fixed vertical frame 4, is a tapered surface 18, the restraining operation of the fixed plate 12 of the hinge is performed automatically. So it's easy, and
You can save labor.
