Description

FIELD OF THE INVENTION

The invention relates to the field of mechanical engineering, namely to hatches made on any surface of vehicle bodies for access both externally to body compartments and for exiting the compartment primarily in a stationary vehicle state.

State of the art

Of the known technical solutions (see ed. St. USSR # 1220941 of 08/30/1984 and autos of the USSR No. 256527 of 06/15/1968), the closest analogue (prototype) is the hatch of a vehicle (see ed. St. USSR No. 256527 dated 06/15/1968), containing a hinged lid that can be rotated on an axis mounted in the coaxial holes of the hinges of the lid and the body, a base fixed to the body and a spring-loaded latch controlled by a rotary lever and pivotally connected to the manhole cover, wherein the latch is made in the form of a rail having a curved longitudinal groove, perpendi ocular to the plane of the opening of the hatch in which the finger of the bracket is located, mounted on the housing on which the leaf spring is attached, interacting with the beveled surface of the rail.

This design of the hatch is complex, has a narrow field of application, since it allows opening and closing the hatch only from the inside and an insufficiently reliable degree of compaction along the perimeter of the hinged lid, since its fastening with hinges does not provide uniform pressing of the lid to the plane of the opening: due to manufacturing tolerances There will always be uneven pressure on the sides of the cover against the body.

Disclosure of invention

The problem solved by the invention is the creation of a universal hatch of the vehicle, suitable for use on any surface of its body (on the roof, on the side walls, including inclined ones, on the bottom), which allows you to open-close it either from the outside or only from the inside , either outside and inside (depending on the design); simple in design, providing a high degree of protection against external sources (moisture, dust, etc.).

The problem is solved due to the fact that the hatch of the vehicle containing a hinged lid in the body of its body, having the ability to rotate on an axis installed in the coaxial holes of the brackets of the lid and the body, the hole of the brackets of the body is made in the form of a longitudinal groove perpendicular to the opening plane of the hatch , the far end wall of which on its outer surface is equipped with a shaped protrusion, interacting in the position of the cover "openly" with a similar profile, the protrusion on the brackets cr The arms and brackets are located in the opening of the hatch housing on the inside of the cover.

Brief Description of the Drawings

The invention is illustrated by the following examples.

Figure 1 in the context (it is the same for both sides of the hatch) shows the hatch of the vehicle in the closed position; figure 2 is a section along aa in figure 1, figure 3 is a section along bb in figure 1; figure 4 - the hatch of the vehicle in the context in an intermediate position of opening its cover (the hatch is open, but not fixed); figure 5 - the hatch of the vehicle in the context in the "open" position.

The proposed hatch of the vehicle contains a hinged cover 1 in the body 2 of its body, which can be rotated on an axis 3 mounted in the coaxial holes of the bracket 4 of the cover and bracket 5 of the body, while the hole of the body brackets is made in the form of a longitudinal groove hatch perpendicular to the plane of the opening 6 7, the distal end wall of which on its outer surface is equipped with a shaped protrusion 8, interacting in the position of the lid “openly” with a similar profile by the protrusion 9 on the brackets of the lid, and all the cover and body brackets are located in the opening 6 of the hatch body from the inside of the cover 1.

The lid 1 can be fixed to the housing 2 in the closed position by many known methods, for example, by means of rotary latches 10 mounted on opposite walls of the lid 1 interacting with the protrusions 11 of the housing.

The implementation of the invention

The proposed design of the hatch of the vehicle operates as follows.

After the latches 10 are unlocked by turning them through an angle of 90 ° (shown in Fig. 4), the cover 1 is moved (by manual action both from the outside and from the inside of the body) by plane-parallel movement on the axes 3 in the grooves 7 of the bracket 5 until the axes stop against the opposite ends of the grooves 7. Then, the cover 1 is rotated upwards on the axles 3 until it stops - this position is shown in FIG. 4. Next, the inverse plane-parallel movement of the cover 1 on the axes 3 in the grooves 7 to the stop (against the wall of the housing) takes place, after which the cover 1 is released and, under the influence of its own weight, the protrusion 9 of the bracket 4 engages the protrusion 8 of the bracket 5, thereby being fixed from closing. Closing the hatch of the vehicle and fixing it on the body are carried out in the reverse order.

From the analysis of the proposed construction it is obvious that it is universal, i.e. allows installation on the vehicle roof, as well as on inclined and vertical walls and in the underbody. In addition, it is possible to open the manhole cover from the outside, only from the inside (if the latch axis 10 does not have an exit to the outside), or from the outside and from the inside (see FIG. 3). The hatch design is simple due to the small number of parts used and ensures uniform pressing along the perimeter of the body opening due to its self-alignment of the axles 3 in the grooves 7 both in the vertical (rotation on the axes) and horizontal (independent movement of the axes in the grooves) directions, which ensures increasing the security of the hatch of the internal compartments of the body from the external environment, including the opening and closing mechanisms of the hatch due to their location on the inside of the hatch.

Thus, as a result of the new design of the cover and body brackets with their location on the inside of the hatch cover, a vehicle hatch of a simple design is obtained, universal in scope and providing effective protection of mechanisms and the internal cavity of the body from external atmospheric influences.

Claims (1)
