Description

TECHNICAL FIELD The present invention relates to a flip-up type elevator gate installed at, for example, a garage entrance.

[Prior Art] A so-called flip-up type gate is known as this type of gate, and in this gate, a pair of relatively low opposing columns that are erected on the left and right sides has a length of about 70 cm at the upper end position. The arm is rotatably fixed to the pivot, the gate main body is fixed to the arm front end side, and the gate main body is rotated around the above-mentioned pivot fulcrum so as to open and close by jumping.

[Problems to be Solved by the Invention] However, in this case, since the gate main body is separated from the support by the arm length, an installation space corresponding to the length is required in the front-rear direction. For example, if there is an obstacle such as a flower bed behind the entrance, it will be difficult to install the columns. Also, since the lower end of the gate body draws an arc trajectory back and forth and is jumped up from its fixed position, it is inevitable that a dead space will occur on the front side of the gate, while on the other hand, if a vehicle etc. approaches it, it may not open and close. Not only that, but there is also the risk that the gate body will collide with children and vehicles during opening and closing operations.

The present invention has been made in view of the above conventional problems, and provides a flip-up type elevating gate that has a small installation space, does not cause the fixed dead space, and is not dangerous during opening and closing operations. The purpose is to

[Means for Solving the Problem] In accordance with this object, according to the present invention, the gate main body is of a vertically elevating type, and at the upper position of the column, the gate main body is flipped up in a bending overlapping manner so as to be folded. In the first aspect of the present invention, a pair of up-and-down vertical support shafts projecting in close proximity to the upper ends of both sides of the support shafts are vertically connected to each other. An upper panel of the main body for raising and lowering the elevator, which is provided with a main roller for raising and lowering and a sub-roller for pivoting and hoisting the lower portion, and a hinge that is flexibly connected to the upper panel in a forward and backward direction and is projected at both lower ends. The lower panel of the main body for raising and lowering the elevator, which has the main roller for vertical raising and lowering on one support shaft, the main guide for the main roller vertically installed in a vertical direction, and parallel and close to the main guide and also in the vertical direction. Vertical Continuing with the installed vertical part and the upper end of this vertical part, a jumping rotation that bends in the front-back direction for the sub-roller forced rotation that follows the circular arc trajectory centered on the top roller top dead center spindle position of the upper panel And a pair of opposed columns having a sub-guide for a sub-roller having a section, and a raising / lowering means for the raising / lowering gate body or a raising / lowering auxiliary means, In addition, the main part is shared with this gist, and in claim 2, at the top dead center of the main roller of the upper panel, one end of the sub guide is opened in a superimposed manner with respect to the vertical part of the main guide, and jumping up. A long groove-shaped support shaft guide for the sub-roller support shaft that is provided so as to rotate and intersect with the rotation portion, and a main shaft formed by overlapping one end with the main guide at the top dead center. For the upper panel, which is integrally provided with a curved sliding contact guide for the main roller support shaft, which is provided so as to partition the receiving hole for inserting the roller support bearing at the rear and to intersect with the main guide in a rotating manner. The present invention relates to and is a gist of a flip-up type elevator gate characterized in that a spindle holder is additionally provided on one or both of the pair of opposed columns of claim 1.

[Operation] In the present invention, in both of the closed states, the gate main body for raising and lowering is positioned below the pair of opposing support columns to partition the inside and the outside.

In the gate 1 of each of the above examples, as already known,
The gate body 2 is manually or electrically assisted by lifting assisting means provided as necessary, and the gate main body 2 is in a closed state.
8 rises from below, and when the rise of the gate main body 2 stops at the top dead center of the main roller 8, the sub-roller 9 of the upper panel 3 is introduced and guided by the flip-up rotation unit 26 and forcedly rotated. The upper and lower panels (3, 11) are flipped up in a bending and overlapping manner, and are folded horizontally on the back side between the pair of struts (18, 18), and by the opposite operation, they are lowered and returned to the closed state.

Furthermore, FIGS. 9 to 12 show an embodiment according to claim 2 of the present invention in which a support shaft holder 41 is additionally provided to the flip-up type elevator gate 1.

The support shaft holder 41 is made of thick-walled steel with a thickness of 2.5 mm and has a flat plate shape of about 12 cm in length and about 9 cm in width. The support shaft guide 42, the receiving hole 43, the shaft support hole 46 and the rotation are formed by notching this. A guide groove 48 is provided.

The support shaft guide 42 has a rear end that fits the radius 9 mm of the support shaft 7 in the sub-roller 9 and one side is tapered, and one end, that is, the lower end is open and a downward wide elongated groove of about 5 cm in depth is formed. The receiving hole 43 is approximately 2.5 cm wide and is also formed in the shape of a groove having a slightly S-shaped meandering shape with one end or lower end opened similarly. The arm piece 44 is formed laterally with a curved sliding contact guide 45 defining the receiving hole 43.

This curved sliding contact guide 45 follows an arc with a radius of 18 mm.
It is provided in the range of 0 °, and the protruding end of the arm piece 44 following the sliding contact guide 45 is also curved outward.

In the present example, the support shaft holder 41 includes a pair of opposing support columns 18,18.
Of the main roller 8 in the upper panel 3 are rotatably fixed to the respective positions near the top dead center of the main roller 8 about the fixed shafts 47 of the shaft support holes 46. In this fixed state, the support shaft guide 42 moves the support shaft guide 42 to the sub guide 24. Is positioned above the vertical portion 25 of the vertical portion 25 so as to overlap with the vertical portion 25 so that the support shaft 7 of the sub-roller 9 can be received from the open side of the lower end of the sub-guide 24. So that they can rotate and intersect.

At this time, the lower end open side of the receiving hole 43 is positioned above one of the main guides 20 so as to be able to receive the support shaft 6 of the main roller 8 in the upper panel 3 and define the receiving hole 43. An arm piece 44 having a curved sliding contact guide 45 is adapted to pivotally intersect the main guide 20.

With this structure, the support shaft guide 42 of the support shaft holder 41 is used for the support shaft 7 of the sub roller 9, and the receiving hole 43 and the curved sliding contact guide 45 are used for the support shaft 6 of the main roller 8. As shown in the action column, the support shaft 7 of the sub-roller 9 rotates the support shaft holder 41 so that the curved sliding contact guide 45 of the support shaft holder 41 holds the support shaft 6 of the main roller 8.

In this example, the support shaft holder 41 is fixed to the main guide 20.
A fixed shaft 47 with respect to the main pillar body 19 together with a stopper 50 that determines the top dead center of the main roller 8 that is disposed above in a fitting manner.
It is fixed integrally by.

Further, in this example, at the time of this fixing, a pin with a head or a screw 49 standing upright on the side of the column 18 is further passed through the rotation guide groove 48, whereby a spindle holder centered on the fixed shaft 47 is provided. The rotation of 41 is curvedly guided laterally so that the main shaft holder 41 holds the main roller 8 with respect to the main shaft 6 more reliably at a fixed position.

Reference numeral 5 in the drawing denotes a bracket in which the brackets 5a and 5b are integrally formed in order to install the support shafts 6 and 7 on the gate main body 2.

In FIG. 9 to FIG. 12, the main body 8 of the upper panel 3 is lifted by raising the gate main body 2 in the gate 1.
When the butt collides with the stopper 50, the support shaft 6 of the main roller 8 is in the receiving hole 43, and the support shaft 7 of the sub roller 9 is a support shaft guide.
Since the sub-rollers 9 are engaged with each other in the flip-up pivoting portion 26, the support shaft guide 42 pivotally intersects the flip-up pivoting portion 26, and the support shaft holder 41 is moved. It is forcibly rotated forward, whereby the curved sliding contact guide 45 keeps the support shaft 6 of the main roller 8 in a lower support state with the top dead center position as a fixed position.

By the way, in the flip-up type elevator gate of the present invention, the height dimension of the gate body is substantially equal to the total height dimension of each panel. Upper panel, 2l lower panel, l
It is also possible to add a lower panel of 3 and make a total of 3 panels. In this case, the pair of support shafts will be at their respective center positions in the 2l lower panel.

In addition, the hinge connection between panels is not only various hinges that are metal,
A so-called full-surface hinge made of aluminum, which is integrally provided so as to be freely fitted into the frame of the panel, may be used.

In addition, in the above-mentioned embodiments, the spindles with the main rollers of the upper panel and the lower panel are both biased back and forth, but when the wire is used for the lifting means and the lifting assisting means, the panel with the wire is used. In order to prevent the interference with each other, each support shaft and the main roller provided on it are arranged on the same vertical line by further installing a roller that avoids that position or by fixing the wire only to the upper panel. While installed, it is possible to unify the main guide.

On the other hand, if the main roller and the sub-roller are each single support shafts, they can be rotatably attached to the support shafts so that a plurality of them can be provided vertically or laterally by using a guide plate or the like. It is not always necessary to be single as in the embodiment.

Further, in order to provide the lifting assisting means, in addition to the structure using the above balancer, for example, a structure may be adopted in which the gate main body is similarly hung and the wire is wound by the upward coil spring urging force.

Although the cross girders are arranged between the columns in the above-mentioned embodiment, if the elevating means or the elevating / lowering auxiliary means can be built in the columns, it is not necessary to provide the cross girders.

Further, the spindle holder of the present invention is particularly effective to be installed on both of the opposing columns for smooth opening and closing of the gate main body, but it can also be installed on one of them.
In this case, it may be necessary to take appropriate measures such as no twisting of the gate main body and suppressing the longitudinal swing of the main roller support shaft.

The positional relationship between the support shaft guide and the receiving hole follows the relative positional relationship between the pair of front and rear displacement support shafts of the upper panel, but as long as this is maintained, the shape etc. is arbitrary, and in each case of strong wind etc. In order to ensure the engagement of the support shaft, a projection piece reaching the support pillar is provided on the support shaft holder side together with or instead of the above-mentioned flip-up rotation portion, and the support pillar is engaged with an arc-shaped guide. Alternatively, a lock device may be provided between the support and the support so that the lock is released when the gate main body is raised.

In addition, it is good practice to avoid forming a sharp-angled portion of the spindle holder as much as possible to make the whole more disk-shaped to prevent danger, and when a sharp-angled portion is formed, the flip-up rotation part side always projects. It is preferable that this part is not exposed or that a cover is attached.

As described above, the present invention does not violate the gist of the invention.
Each specific shape of the gate main body, each panel, support shaft, main roller, sub-roller, jumping rotation part, lifting means or lifting assisting means, support shaft guide, receiving hole, curved sliding contact guide, support shaft holder, etc. The structure, dimensions, materials, and their relations can be variously changed, and need not be limited to those shown or described in the above embodiments.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

That is, in claim 1, as described in the action column,
A new hoisting type hoisting system that is located below the opposing stanchions when closed, and when it is opened, it can fold the gate main body for lifting up and down in a bent overlapping state at the uppermost position to level or close to it. May provide a gate.

In the closed state of the gate main body, the gate main body is arranged on the same plane as the pair of opposing struts or within a slight protrusion width, and the jumping due to the opening is performed in the closed state position of the gate main body. Since it is not touched, the installation space as a gate is small, the standing structure such as a rear flower bed is not an obstacle to the installation, and a dead space near the gate can be prevented.

In addition, since the gate body is bent and overlapped so that the gate body is bent and overlapped, the range of rotation is small, and since the rotation is performed above the pillars, the gate body collides with children and vehicles during the jump. The risk of contact can be prevented as much as possible.

In addition, the gate of the present invention is provided with the gate main body raising / lowering means or the raising / lowering auxiliary means, and the raising / lowering and the turning of the gate main body are performed by dedicated main guides, main rollers for the sub guides, and sub rollers. ， Even if the gate main body is raised and lowered and jumped up automatically or by means, it is possible to obtain extremely stable and reliable operation.

In addition to the above effects, the support shaft holder automatically supports the support shaft of the main roller under the opening movement of the gate main body when the gate main body is opened, in addition to the above effect. The main roller is held in a fixed shape, and the support shaft is held in a fixed position at the top dead center of the main roller, and when the gate main body is folded, the support shaft is set to the center position to prevent the influence of the vertical load applied to the main shaft and prevent the gate door from being affected. The opening and closing of the main body can be facilitated.

Therefore, even if the angle between the upper and lower panels is small and the folds are more folded, the vertical load on the support shaft of the main roller can be distributed to the stanchions, and the load difference from the vertical load at the bottom dead center in the open state of the gate body. Since it is possible to make it as small as possible, it is sufficient for the elevating means and the elevating assisting means provided on this to be basically opened and closed based on the vertical load at the bottom dead center side, and a load difference is assumed. It is possible to effectively prevent the complication and the trouble of opening and closing due to the operation.

Further, the additionally provided spindle holder is relatively simple and inexpensive, so that the overall cost will not be greatly increased and a failure will not occur.
