Description

The utility model relates to transport engineering, and more specifically to the design of emergency ventilation hatches of vehicle roofs.

There are various designs of emergency ventilation hatches of vehicle body roofs (see, for example, the USSR AS No. 597585, 737256, 1281471, 1243966, RF patents No. 2026202, 2047503, 2047504, WIPO No. 2076777, EPO No. 0451583 , 0451606, 0325380, Germany No. 1404999, 1240424, 1259216, 1286928, 1630020, Great Britain No. 1350844, 1397251, 1097145, 1156755, France No. 1117636, USA No. 2810334, 4101159, 4329917, Spain No. 2278901, 2125583, Finland No. 2005570 and others.).

Such hatches, although they allow ventilation of the vehicle’s interior, as well as allow for the evacuation of people during an accident, however, due to a number of design features of these hatches due to increased requirements for modern vehicles and their components, in many cases the use of these hatches substantially limited. For example, in some cases, manhole covers are made double of two sheets, which leads to increased rigidity and impairs the tightness of the hatch in the closed position. In some hatches, the opening / closing mechanisms easily fail due to blows from the top of the hatch with branches or other objects when the vehicle is moving. In addition, the control knobs of the known hatches are either too bulky and inconvenient to operate, or too fragile and often break.

The closest solution in technical essence and the achieved effect from its use to the claimed one is the well-known design of the emergency ventilation hatch of the vehicle body roof according to the patent of the Russian Federation for utility model No. 80145, B60J 9/02, January 27, 2009, containing

The emergency ventilation hatch of the vehicle body roof has a frame 1 (see Fig. 1) fixed to the body roof, a cover 2 (see Fig. 1, 4) between the cover 2 and frame 1 around the entire perimeter there is a seal 3 ( see Fig. 1). The hatch has four mechanisms for opening / closing the lid 2 with stops 15 (see Fig. 3, 7, 8, 10, 12) for lifting the lid 2 during ventilation of the passenger compartment located symmetrically at the corners of the hatch.

Each mechanism for opening / closing the lid has a handle 4 (see Fig. 1, 2, 5, 6, 7, 11, 12, 13, 14), mounted on the lid 2, and an L-shaped vertical guide rod 5 (see Fig. . 1, 3, 6, 7, 8, 9, 10, 14) in the form of a flat plate mounted with the possibility of vertical movement and tilt sideways in the vertical guide groove 6 (see Fig. 8, 9, 10) of the horizontal housing 7 ( see Fig. 1, 3, 7, 8, 9, 10, 12), made in the form of a parallelepiped, and fixedly attached to the inner side of the frame 1. The rod 5 is made with copy surfaces 8 (see Fig. 8) in the form of two waved profiles made on both narrow lateral sides, inside each horizontal case 7, along its axis of symmetry there is a through longitudinal cylindrical hole in which two mushroom-shaped sliders 9 are installed symmetrically towards each other with the possibility of longitudinal movement (see Fig. 8, 10) cavities inside, with cylindrical shanks and with heads having hemispherical working parts that smoothly transition into cylindrical parts. The contours of the hemispherical working parts of the heads coincide with the contours of the troughs of the wave-shaped copy surfaces of the rod 5, in addition, the hemispherical working parts of the heads of the sliders are made interacting with the corresponding copy surfaces on the rod, and each slider is spring-loaded relative to the rod using a spring 10 (see Fig. 8, 9, 10) and a support pin, cut along the entire length, of the pin-regulator 11 (see Fig. 8) installed in one of the transverse holes 12 (see Fig. 3), made in a horizontal case near its ends of the perpens ikulyarno axis of the longitudinal holes at different distances from the center of the horizontal body.

New is that the cover 2 is made of flat tempered glass, and each handle 4 is connected to the L-shaped rod 5 by means of a lock connection 13 (see Fig. 12, 14), which allows you to disconnect the handle from the rod during emergency discharge (splitting) glass cover 2, while in each rod there is a longitudinal slot 14 (see Fig. 9, 10), into which the stops 15 are made in the form of locking screws and screwed into the threaded hole 16 (see Fig. 7) of each horizontal housing.

The proposed emergency ventilation hatch is operated as follows.

Before starting operation, in the process of assembling the hatch assemblies, the response force of each slide is calibrated in its working positions, selecting the desired spring stiffness, pressing the slider by selecting the hole at the right distance from the center of the housing to install the pin-regulator.

After that, all nodes of the hatch are put in place, the locking screws 15, which serve as limiters, are screwed into the threaded hole 16 of the corresponding horizontal housing 7. All mechanisms, except their controls, are closed with protective and decorative lining, and the hatch is ready for immediate operation.

To ensure ventilation of the cabin, the hatch can be opened either completely by pressing the handles 4 in pairs and lifting the cover 2 all the way to the stop screws 15 in the upper or lower part of the rod 5 slot, or partially with reliable discrete locking of the cover 2 in its any intermediate position using spring loaded sliders. At the same time, the cover 2 is discretely fixed depending on the number of depressions on the profiles of the wave-like copy surfaces of the rod, for example, in two positions: “closed” and “open”.

In the event of an accident, a lid made of tempered glass breaks with the help of a hammer or any solid object, the handles crumble with glass.

After that, the hatch is ready for the immediate evacuation of people from the passenger compartment of the vehicle.

Using the claimed utility model allows you to:

1. To increase the reliability of the emergency ventilation hatch and reduce its weight and size characteristics by simplifying its design and reducing the number of highly loaded parts while ensuring a high degree of tightness of the structure.

2. Provide a significant reduction in time for the immediate evacuation of people from the cabin.

3. Increasing labor productivity in the manufacture of components of the hatch and its assembly, to reduce its cost.

Industrial applicability is obvious. The applicant performed a prototype, which proved the feasibility of the tasks for this utility model, for the implementation of which no new special equipment is required.
