Description

Stacking Door

The present invention relates to a stacking door. More particularly, the present invention relates to a stacking door that can be easily lifted by installing a torsion spring so as to offset the weight of the blocking plate during the opening and closing operation of the door. will be.

In general, the front of the building, such as stores, garages, logistics facilities, etc. are provided with openings for people or vehicles to enter and exit, and various types of doors are installed as a means for blocking the opening and opening and closing as needed. .

In particular, industrial doors are selected to be suitable for the purpose of use, and are installed in necessary openings of buildings in places where insulation, soundproofing, or sealing of various production plants, distribution centers, aircraft hangars, and fire station garages are required.

Conventionally used industrial doors include roll up doors, hanger doors, folding doors, overhead doors (OHD) Various types of doors are used, such as a stacking door, and the characteristics of each industrial door are as follows.

The roll up door is opened and closed vertically by being wound on the upper self moving system by the tensioning action of the spring and the operator according to the size and weight of the door. It is widely used in places that need to open and close large openings such as airplane hangars, military units, logistics centers, and the like.

The hanger door is a sliding door in which rails are constructed along the outer wall or inner wall of the building, and rollers mounted on the blocking plate are opened and closed by rolling and sliding through the rails. .

Hanger doors are mainly used in the construction of factories and warehouses, etc., where the size of the doorway should be relatively large, and it is used in industrial construction because it is easy to bring goods in by using wide openings in a narrow space. However, the hanger door is inadequate for use in a distribution center that requires a large number of doors because the door is closed and the door is opened sideways.

Folding door is a method of installing a track on the upper side and opening or closing the door by opening or folding a blocking plate connected to the hinge by the upper roller. It is used in a narrow place.

Overhead doors (OHDs), unlike conventional hanger doors or shutters, are doors that are opened and closed manually and automatically by a door in which a blocking plate is quickly opened or closed horizontally or vertically along a ceiling or a wall.

The overhead door is a roller that moves along the track by using the spring tension or restoring force of the upper, and a plurality of blocking plates are coupled to the upper and lower hinges are bent to open and close the door up and down.

Overhead doors have the functions of protecting products and facilities in buildings, quickly entering and exiting them, maintaining a pleasant environment in the workplace, protecting the internal temperature, and blocking the ingress of outside air, and in buildings requiring thermal management, especially fire departments, warehouses, factories and logistics centers. Provides an optimal environment for back.

However, the overhead door has a problem in that a conventional overhead door cannot be used because the space between the head of the door entrance and the ceiling is too large.

A stacking door is used as a method for overcoming the problems of the overhead door caused by the space constraint, and the characteristics thereof are as follows.

Stacking doors are vertically raised when the barrier plate opens and closes so that they overlap in parallel at the top of the shutter box.The advantages of the existing overhead door and the head room between the head of the wide door entrance of the ceiling are It is a new door that can be installed in a small box space without the need.

The stacking door adopting this new method is an industrial door that can be effectively used in the case where it is difficult to store the ceiling such as a pipe at the upper part where the blocking plate is stored.

Various types of industrial doors having the above characteristics are equipped with automatic or manual power means of a suitable type according to the height and width of the opening, so that openings of various industrial facilities and buildings can be blocked and opened and closed as necessary. It is used as a means to be able.

By the way, in the case of a conventional stacking door among the industrial doors described above, which can be installed in a small box space without the need for a wide head room of the ceiling, the stacking door by manual or automatic power means The following problems existed during the opening and closing operation.

In the opening operation of the stacking door, the blocking plate rises vertically by manual or automatic power means and overlaps in parallel in the upper part of the shutter box. There is a problem that the load is applied to the power means in the direction, the barrier plate is not easily lifted.

In order to solve the above problems, the present invention provides a torsion spring as a means for obtaining a balancing force necessary to offset the weight of the blocking plate when the blocking plate is vertically raised during opening and closing operation of the stacking door by manual or automatic power means. It is an object of the present invention to provide a stacking door that can raise and lower the blocking plate more quickly and facilitate the operation.

In order to achieve the above object, the present invention, the opening and closing of the door is guided by the vertical guide rail 130 and the blocking plate receiving rail 140, the blocking plate 120 is received in parallel with the lifting and lowering; A vertical guide rail 130 which contacts the rollers 230 provided on both sides of the blocking plate 120 to guide the blocking plate 120 so that the lifting and lowering of the blocking plate 120 is free; A blocking plate accommodating rail 140 for accommodating the blocking plate 120 rising in the vertical guide rail 130 in parallel; First driven shaft coupled to the left and right box-shaped frame 114 to be rotated by the motor 160, the motor 160 installed in the frame 110 to allow the blocking plate 120 to move up and down A lifting device 150 comprising a 172 and a second driven shaft 424; A frame 110 supporting the blocking plate 120, the vertical guide rail 130, the blocking plate accommodating rail 140, and the lifting device 150; And a torsion spring for canceling the weight of the blocking plate 120 during the opening and closing operation of the stacking door so that the stacking door can be easily lifted and lowered, so that a restoring force acts in the direction in which the blocking plate 120 is raised.
