Abstract

FIELD: transport engineering.

SUBSTANCE: invention relates to vehicles and other objects with throw-open doors. Proposed door unit contains throw-open door installed in door aperture and hinges and it is furnished with device to hold door in wide-open state. Device is made in form of clamp with conical hole and body with spring-loaded lock. Lock is provided with cone at one side to engage with clamp hole, and shank with handle at other side. Clamp is rigidly secured on inner side of door from side of hinges, and body is rigidly secured on inner side of door aperture wall.

EFFECT: improved operating characteristic and safety in operation of vehicle owing to reliable locking of door in wide-open position.

Description

The present invention relates to vehicles or other objects having swing doors.

Known door block of the vehicle [1], selected for the prototype, containing a swing door installed in the doorway, hinges with a radius transition that limits the angle of opening of the door, as well as an additional belt stopper for opening the door.

The disadvantage of this design is that the limiters do not fix the door in the open position, and from the influence of the wind or when the vehicle is on an inclined surface, the door closes unauthorized. The arbitrary closing of the door reduces the usability of the vehicle (object), which impairs its performance in general. In addition, having sufficient weight, the door, when unauthorized closing, can injure a person in the doorway, which reduces the safety during operation of the vehicle (object).

The task of the invention is to increase the operational characteristics and safety during operation of the vehicle (object) by ensuring reliable fixation of the door in the open position.

To solve this problem, a door unit comprising a hinged door and hinges installed in the doorway, according to the invention, is equipped with a device that fixes the door in the open position. The locking device is made in the form of a bracket with a conical hole and a housing with a spring-loaded lock. On the one hand, the latch has a cone for interacting with the bracket hole, and on the other, a shank with a handle for disengaging the latch from the bracket. The bracket is rigidly fixed to the inner side of the door from the hinge side, and the body is rigidly fixed to the inner side of the wall of the doorway. When the door is closed, the latch is pressed against the bracket under the action of the spring, and when the door is opened, it slides along the bracket and when the door reaches the maximum opening angle it automatically falls into the conical opening of the bracket, reliably locking the door in the open position. Using the handle, a person provides operational control of the latch, being both inside and outside the vehicle (object).

The conical shape of the hole and the retainer provides a backlash-free connection of the retainer to the bracket, as well as its easy forced removal from the hole. Thanks to the spring, the latch is constantly pressed against the bracket and automatically engages in the hole when the door is opened at a predetermined angle.

The proposed technical solution provides reliable fixation of the door, which increases the operational characteristics and safety during the operation of the vehicle (facility).

This technical solution is illustrated by graphic materials, where Fig. 1 schematically shows a door unit with a door in the open position, Fig. 2 shows a view along arrow A.

The door unit comprises a wall 1 of the doorway, door 2, hinges 3. On the inner side of the wall of the door 2, a bracket 4 with a conical hole is rigidly fixed. On the inner side of the wall 1 of the doorway, a housing 5 is fixedly fixed, in which the latch 6. is placed. On the one hand, it has a cone, which, when the door is open, sinks into the hole of the bracket 4 under the action of the spring 7. On the other hand, the latch has a shank 8 with a handle 9. To close the door, the latch 6 using the handle 9 is removed from the hole of the bracket and the door is freely closed.
