Abstract

PROBLEM TO BE SOLVED: To ensure adaptability through order or combination change for making possible stock management for every sub assembly by constructing a functional unit of a door as the sub assembly of a module structure that can be partially connected or removed. SOLUTION: A door mechanism is constructed of modules 10-60 and screwed by use of a flange joint so that the mutual removal can be made. A first brake shaft 14 is meshed with an outer shaft 12 of a gear module 10 and provided at a lower part of the door mechanism, and also connected to a second brake shaft 42 of a brake module 40 by screw. The shaft 42 is inserted into a hole provided in a mannual operation module 30 and a counter shaft module 20. In the case where the module 20 is removed, the module 30 is connected to the module 10 on one hand while to an adaptable module 50 on the other hand. The shaft 14 can be connected to the shaft 42 in this way. Accordingly, mounting and demounting of structural element can be made without the provision of new door mechanism.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door mechanism having separate functional units, particularly for an industrial door.

[0002]

2. Description of the Related Art Such a door mechanism generally includes a drive unit and a gear unit, and the operation of an output shaft of the drive unit is transmitted to a door shaft usually provided in the gear unit. The door mechanism should be further equipped with a counter shaft to select the appropriate power transmission according to the conditions required in each case, and a brake device to control the operation of the door in all states of operation. Is required. Further, if the drive unit breaks down or the brake device does not function, it is necessary to manually operate the door mechanism.

[0003]

The door mechanism must be capable of a number of different configurations to accommodate various requirements. As a result, the manufacturing process of the door mechanism and the inventory management become more costly. Further, since the conventionally known door mechanism cannot be used with various modifications, it is difficult or difficult to use the door mechanism.
When replacement is required, it must be completely replaced with a correspondingly adapted configuration.

[0004] The present invention has been made in view of such problems, and an object of the present invention is to further develop a general door mechanism to increase the flexibility of use.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a general door mechanism in which a functional unit is configured as a sub-assembly having a modular structure which can be at least partially detachably connected to each other. Achieved by In this way, sub-assemblies that perform different functions as required can be releasably connected to one another in any order or combination, thereby allowing the door mechanism to be flexibly adapted to the requirements of the individual case. It can be adapted. That is, the door mechanism can be adapted to the demand only by providing the subassembly corresponding to the function required for the door mechanism. Similarly, individual subassemblies can be added or removed as requirements change. The subassemblies can be configured so that each subassembly can be connected to any other subassembly.

[0006] This further simplifies the manufacturing process, since it is only necessary to manufacture individual subassemblies of the module structure. In the past, it has been necessary to manufacture a number of different door mechanisms to meet various requirements, but according to the invention this is not necessary. As a result, the manufacturing process is relatively simple, which is advantageous in cost. In addition, only the subassembly having the module configuration needs to be managed in inventory, and it is not necessary to store finished products of various door mechanisms. This is advantageous in terms of inventory management in terms of cost.

It is particularly advantageous if the subassemblies can be connected to one another by screw connections. In this way, the subassembly can be a structure with flanges or corresponding holes for the passage of screws.

According to another aspect of the invention, the sub-assembly comprises one or more of a gear module, a countershaft module, a manual operation module, a brake module, an adaptation module, and a drive module. Here, the gear module transmits the rotation of the output shaft of the drive module to the door shaft of the door unit. The transmission ratio of the door mechanism can be changed by the countershaft module. The manual operation module plays a role of operating the door unit even when, for example, the drive module of the door mechanism is stopped by shutting off power. The brake module controls the operation of the door in all states during the operation,
This is particularly necessary if the door is a heavy industrial door. In addition, it is possible to cope with a case where the length of the output shaft of the drive module is different depending on the adaptation module.

According to the present invention, each single module or a plurality of modules can be configured as one subassembly.

[0010] In another aspect of the invention, the manually operated module comprises a chain or crank for manual operation. The crank can be connected to a manually operated module by a cardan joint.

According to a preferred aspect of the present invention, the manual operation module is configured to be connectable to a gear module or a counter shaft module. This has the effect that the same manual operation module can be used regardless of whether or not the door mechanism according to the present invention includes a countershaft module. Also, the manually operated module can be configured to connect to any subassembly of the door mechanism.

According to a preferred embodiment of the present invention, the adaptation module is configured to be connectable to the drive module and the manual operation module.

[0013] An output shaft connectable to the door shaft and a first brake shaft meshing with the output shaft are provided in the gear module, a second brake shaft is provided in the brake module, and both brake shafts are detachably connected to each other. Can be. Here, brake modules having second brake shafts of different lengths can be provided. This is necessary to adapt the length of the second brake shaft of the brake module to the configuration and number of subassemblies used in the door mechanism according to the invention.
