Description

The present invention relates to furniture installed on vehicles, and can be used as household equipment in the cockpit of passenger aircraft.

The prior art devices for installing containers with drinks, placed in the panel of cars or other objects.

A feature of the placement of such devices is that they are installed next to the driver in the cavity of the dashboard or in the cavity of the armrest and extend horizontally to the level of application.

The need for such devices arises not only among passengers or the driver of a vehicle, but also among crews of aircraft during long flights.

The analysis of the prior art revealed a number of solutions that are most optimal from the point of view of ease of use, technological, designer.

So, in US patent 2510545, CL. NKI 211-74, publ. 06/06/1950, a similar device is described. The device comprises a horizontal tray mounted in the guides, connected by a cable to a stand for supporting containers. The tray extends horizontally to the application position. At the same time, the stand for containers automatically extends.

In US patent 4792174, CL. B 60 R 7/06, publ. 12/20/1988, a similar device is disclosed. This device is a tray mounted in the niche of the dashboard. The niche is placed at a user-friendly height. The tray is intended for placement on it containers with food and drinks. In the extended position, the tray is locked using the lever system.

A similar device holder is presented in US patent 5379978, CL. A 47 F 5/00, publ. 01/10/1995. A niche is structurally provided in the dashboard of the car. It has a table with a hinged cup holder. The table is installed in the guides. The operator of the vehicle, pulling the handle of the table, pushes it out of the niche. At the top of the panel of the table is a holder for drinks, it is pivotally connected to the panel of the table. The operator can raise the holder if there is a need to put a glass with drinks. For stability the holder is fixed.

In US patent 5692658, CL. B 60 R 7/06, publ. 12/02/1997, describes the design of the holder of containers for drinks designed for cars. The holder is installed in the niche of the dashboard in the guides. The design of this holder consists of a housing, in the cavity of which there are two container holders, interconnected by a spring. In the retracted position, the holders are tightened and are closer to each other. In the extended position, the holders exit the cavity of the housing. In the case there is also a container for small items.

A similar device is described in US patent 5765736, CL. B 60 R 7/06, publ. 06/16/1998. The retractable device of the beverage holder has a housing mounted in the dashboard of the vehicle. In the housing in the rails there is a sliding panel with devices for supporting glasses with drinks. The sliding panel moving mechanism consists of a guide mounted on the housing interacting with the sliding block connected through the spring to the sliding panel. The movement of the sliding panel of the holder when it is extended is limited by the length of the grooves-guides of the housing along which the protrusions on the panel move.

A device for fixing beverage containers described in US Pat. No. 3,606,112, cl. In 60 R 7/00, publ. 09/20/1971, made multi-section, telescopic. The guiding devices are also multi-sectional, which ensures a reduction in the dimensions of the device when it is placed on the dashboard of a car. If necessary, pulling the outer panel, the driver of the vehicle or passenger gradually pulls out the first section - the holder for drinks, and then the second section - a link in the form of a box, in the guides of which the holder for drinks moves. The box, in turn, is installed in the guides of the housing located in the instrument panel. The movement of each section is limited by limiters installed in the rails.

In the application FGR 19908130, cl. In 60 To 37/04, publ. 08/31/2000, a device for the holder of dishes with drinks, as well as containers with food or small items. This device is installed on the dashboard panel of the vehicle. It extends horizontally.

In US patent 4417764, CL. A 47 C 7/62, publ. 11.29.1983, a table is presented that extends horizontally to the working position. The table in question is located in the armrest of the vehicle seat. The table contains a housing in which the shelf is placed. The shelf is installed in the guides of the housing. When the shelf is extended, it slides in the guides, there is a mechanism for locking the table in the extended position. The shelf can be made with niches for stationery - paper, pen, pencil, etc., or with holes with supports for fixing containers with drinks.

A disadvantage of the known devices is that they require a place at the level of their application when placed on the dashboard and cannot be used to create a table for the pilot in the cockpit with a side control handle, as Flight indicators are installed on the dashboard in the area where the table is used, but it is impossible to place the table next to the pilot, because when it is pulled forward, the operational aircraft controls installed on the side panels will be closed.

Known technical solutions for the extension of the table from an inclined or vertical relative to the level of application of the position.

US Pat. No. 5,297,709, cl. B 60 R 7/06, publ. 03/29/2005, a holder table installed in the dashboard of a vehicle is described. This table is applicable in those designs where it is not possible to position the holder horizontally in the dashboard. The table has a housing mounted in the cavity of the dashboard. In the case there is an insert in the guides of which a shelf is installed. The shelf has holes for holding glasses with liquid. For installation in the working position, the table is extended completely up, and then turned to the application position. At the same time, the emphasis, ensuring the horizontal position of the shelf, is installed in the place of the table’s turn.

This design of the table requires a place under the legs to place it in the cleaned state. Such a design does not allow placing the table in the area of the driver’s feet, which is necessary when placing the table on the plane with the side handle of the aircraft.

A device for placing beverage containers is described in US Pat. No. 5,692,718, class. A 47 F 5/00, publ. 12/02/1997. This device contains a housing mounted obliquely in the dashboard of the vehicle. In the case there is a sliding element with guides, a drink holder, a base and a return mechanism from an extended position to a retracted position. The sliding element is made in the form of a frame, at the front wall of which a drink holder is pivotally mounted on its lateral sides. Slots are made on the sides of the frame of the sliding element to deepen the side walls of the holder therein. The beverage holder is connected to the base by means of pins moving in the slots of the base. When extending the entire structure and installing it in the working position, one of the walls of the base is a supporting support for glasses. The base is also pivotally mounted on the side walls of the sliding element.

The mechanism for returning from the extended position to the retracted is pivotally mounted on the side walls of the sliding element and is connected to the beverage holder.

When the design of the table is extended to the working position, the sliding element slides in the guides until it stops. Having reached the maximum position, the frame of the sliding element is locked in the extended position. The beverage holder and the base when folded are located inside the sliding element. Pulling down on the front panel of the holder, the driver or passenger raises the holder to a horizontal position. In this case, when the holder rises, the base drops down. The fixation of the open position is ensured by a stop equipped with a torsion spring, which, when a force is exceeded exceeding the spring elasticity, weakens the stop. The drink holder has an opening, the diameter of which is usually equal to the diameter of a standard glass. You can put a container with a drink in the holder, the bottom of the container is supported by a base. When there is no need for the holder, it folds, while the holder and the base are retracted into the frame of the sliding element, and he himself slides into the case.

This design can be placed in the lower part of the instrument panel of the aircraft in the area above the legs of the pilot. However, you cannot use a similar design for the pilot’s table, because it does not contain a hard lock of the open position and cannot be equipped to work with technical documentation. The known device is complex in design and does not protect against folding in case of accidental exposure to the surface of the device.

The present invention is aimed at creating a compact table with a simple design, placed in the dashboard of the aircraft, which can withstand increased loads from vibration and is easy to use (the number of movements required to extend and clean the table should be minimal).

The problem is solved in that the design of the folding table consists of a body located in it with the possibility of linear movement of the strut with a tabletop installed on it, as well as a mechanism for fixing the table in the extended position. The table is equipped with an emphasis on the working position of the countertop pivotally connected to the strut and to one of the ends of the countertop. The other end of the countertop is movably connected to the strut. The emphasis on the working position of the tabletop is connected with the mechanism for fixing the table in the extended position.

The mechanism for fixing the working position of the table is made in the form of a latch pivotally mounted on the strut, connected on one side with the focus of the working position, and on the other with an elastic element also mounted on the strut.

In the folded position of the table, the working surface of the countertop is parallel to the axis of inclination of the strut, and the axis of the articulation of the countertop and the stop is located above the axis of the articulation of the stop with the strut.

A cavity is made in the strut to accommodate the documentation container installed on the countertop.

The countertop is made of two parts pivotally connected to each other.

The strut is installed in the rolling guides located on the housing.

The invention is further illustrated by drawings, which depict:

figure 1 - table in the retractable position;

figure 2 - mechanism for fixing the table in the extended position;

figure 3 is a view of a table with a tabletop raised into position;

figure 4 - the shape of the bracket countertops;

figure 5 is a view of a table with a niche for documentation.

The proposed folding table contains (see FIGS. 1, 2, 3) a housing 1 located in it with the possibility of linear movement of the strut 2. On the strut 2 there is a tabletop 3. The folding table also contains a locking mechanism 4 in the extended position (see FIG. 2).

An abutment 5 of the working position of the tabletop 3 is pivotally connected (see Figs. 1, 3) to the strut 2 and to one of the ends of the tabletop 3. The other end of the tabletop 3 is movably connected to the strut 2. At this end of the tabletop 3, an arm 6 is fixed on its lower surface with axis 7. The ends of the axis 7 (trunnion) are installed in the guides made in the form of grooves in the walls of the strut 2 (figure 1). The axis 7 is mounted in the bracket 6 pivotally (with the possibility of rotation). Swivel joints of the stop 5 of the working position of the countertop 3 with a strut 2 and with a countertop 3, as well as the movable connection of the countertop 3 with a strut 2 provide folding of the table. One of the possible forms of the bracket 6 is shown in figure 4. In a preferred embodiment, the strut 2 in cross section is made in the form of a channel.

The emphasis 5 of the working position of the countertop 3 is connected with the locking mechanism 4 of the table in the extended position.

The locking mechanism 4 of the working position of the table is made (see figure 2) of the latch 8, pivotally mounted on the strut 2. The latch 8 is connected through a cable 9 and a tension mechanism 10 of the cable 9 with a stop 5 of the working position of the tabletop 3 (see figure 3) . Also, the latch 8 is pivotally connected to the elastic element 11, which can be fixed on the strut 2. In the example given on graphic materials, the elastic element 11 is fixed on the wall of the strut 2. The elastic element 11 is made in the form of a spring operating in tension. The latch 8 has a protrusion (tooth) of a curved shape. Holes are made in the strut 2 and the corresponding wall of the housing 1, during combination of which, in the process of extending the table, the tooth of the latch 8 is lowered into the formed recess and, thus, fixes the table (see figure 2).

In the folded position of the table, the working surface of the countertop 3 is parallel to the axis of inclination of the strut 2, and the axis of articulation of the countertop 3 and the stop 5 of the working position of the countertop 3 is located above the axis of the articulation of the stop 5 of the working position of the countertop 3 with the strut 2 (see Fig. 1). The implementation of the mounting points of the stop 5 of the working position of the countertop 3 with other elements of the design of the table spaced in the kinematic diagram of the device to avoid the dead point in the operation of the whole mechanism.

In the strut 2, a cavity can be made to accommodate the documentation container installed on the countertop 3 from the side of its lower surface. An example of a table with a niche for documentation is shown in Fig.5.

The countertop 3 can be made of two articulated interconnected parts (not shown in the drawings).

The strut 2 is installed in the rolling guides located on the housing 1 (the design is not shown in the drawings). The use of rolling guides makes it easier to extend / clean the table.

It should be noted that the strut 2 can be made in the form of a beam with a channel cross-section, in the form of a tray and in the form of a rigid frame, in order to avoid distortions of the structure. For the same purpose - to avoid various distortions during the installation of the table and operation - it is preferable to stop 5 of the working position of the tabletop 3, as well as the bracket 6 of the tabletop in the form of integral elements, U-shaped in cross sections. In addition, when the emphasis 5 of the working position of the countertop 3 U-shaped, the countertop 3 is more stable, because the area of the support is increasing. In addition, the reference points are spaced from each other relative to the axis of symmetry of the table. To avoid distortions of the connection of the countertop 3 with the strut 2, the emphasis 5 of the working position of the countertop 3 with the countertop 3 and with the strut 2 must be made coaxial.

The table itself, its body, is placed obliquely in the dashboard, parallel to the bottom wall of the dashboard.

The described construction is used as follows.

To set the table in the working position, the operator (in our case, the pilot), taking the handle 12 of the countertop 3, pulls the countertop 3 with the brace 2 out of the niche in the dashboard 13 by the movement (see Fig. 1).

Pulling the strut 2 and the countertop 3 to the extreme position, the pilot, acting through the handle 12 on the countertop 3 parallel to the floor plane, lifts the countertop 3 to the horizontal position, which simultaneously pulls the stop 5 of the working position of the countertop 3. The stop 5 of the working position of the countertop 3, turning on the axis 14, rises to the working position, while the axis 7, which connects the countertop through the bracket 6 to the strut 2, moves along the groove 15 of the strut 2 to the extreme right position, shifting the countertop 3 towards the dashboard. Based on the axis 7 mentioned above and on the stop 5 of the working position of the countertop 3, the countertop 3 is fixed in the working position (see figure 3).

With the full extension of the strut 2, the hole made in it for the latch 8, is combined with the hole of the housing 1.

Simultaneously with the translation of the tabletop 3 into the horizontal position, the stop 5 of the working position of the countertop 3, moving out of the folded position, moves the axis of fastening of the cable 9 on the stop 5 forward relative to the axis of attachment 14 of the stop 5 of the stop 5 of the working position of the countertop 3 with a strut 2, thereby easing the tension of the cable 9 (cm Fig. 1). In this case, the elastic element (spring) 11 (see Fig. 2), acting on the latch 8, expands it clockwise, introducing it into engagement with the hole made in the housing 1, thereby fixing the position of the strut 2 relative to the housing 1, mounted on dashboard 13.

To clean the table, the pilot, pulling the handle 12, puts the countertop 3 parallel to the strut 2. Axis 7 moves along the grooves of the strut 2 towards the pilot, the emphasis 5 of the working position of the table from a vertical position fits inside the strut 2. The latch 8 is disengaged from the hole case 3. With further movement, the pilot parallel to the direction of strut 2 pushes the table into the dashboard 13.

In the lowered position, the countertop 3 is parallel to the strut 2, the emphasis 5 of the working position of the countertop 3 is located inside the strut 2. In this case, the cable 9 connecting the emphasis 5 of the working position of the countertop 3 through the tension mechanism 10 with the lock 8, is tensioned and, overcoming the force of the spring 11, unfolds the lock 8 counterclockwise, providing free movement of the strut 2 inside the housing 1.

The floor of the cockpit is parallel to the horizontal of the aircraft. Since the housing 1 is installed obliquely to the floor of the cabin, spontaneous extension upward strut 2 from the housing 1 does not occur and the table is reliably located inside the dashboard 13.

The described design is distinguished by simplicity in execution, ease of use. The extension of the table, as well as its cleaning, takes place in two movements of the pilot.
