In Fig. 1 and Fig. 2 are the basic schemes of the technical supplement (further TE).

In Fig. 1 is a TE, which has a body 2 made of plastic, light metal or other substances.

The TE is placed in the trunk of the car. The Kontu ren of the trunk are shown in position 1 .

The body 2 contains the support frame 3 and side walls 4 . The frame 3 has an agreed (conditional) longitudinal axis 5 , which is shown in FIG. 2. The frame 3 contains two additional inner stands 6 and 7 , which are fixed parallel and sym metric to this longitudinal axis 5 . The stands play the role of side walls and delimit from the frame on two zones - right 8 and left 9 , which are symmetrical with respect to the longitudinal axis 5 .

The frame has an end wall. The shape and size of the frame match the trunk. The body 2 can be universal or of different size types. The inner surfaces of the side walls and the additional stand have recesses (items 10 , 11 / Fig. 2) in the form of cylindrical paired holes. Each paired hole is at a height, but is not a continuation of another paired hole in another zone, that is, they should be checkered. The number of holes is determined by calculation.

In Fig. 2, the rollers (e.g. 12 , 13 , 14 ) are drawn which are mounted in each paired hole from each zone. All rollers from both zones are perpendicular to the longitudinal axis 5 . The diameter of the rollers and the holes is the same. Each roller contains one or more haystacks (items 15 - 19 ). A technical socket is to be understood as: various technical adaptations that are freely or permanently mounted on the roller or on the axis (e.g. roller, wheels, sleeve). All bushings - Fig. 1,2 - are set according to the length of the rollers so that they can rotate freely. All sockets from each zone are placed in a checkerboard shape ( 15 , 16 and 17 ). In addition, the technical supplement (TE) contains a panel (item 21 / Fig. 1) that is rectangular in shape.

The technical supplement can have one or more panels; the amount of which is determined on the basis of the invoice. The panel is placed in the working state on the upper surface of the socket: the free surface of the panel is used for loading 22 . When the panel comes to the ordered space, it is fixed on the frame. And the load is fixed to the frame.

Fig. 3 shows the scheme of the construction of the adjustment for fixing the panel. The construction of the adjustment can be different, e.g. B. as the grip 23 , which is mounted on the frame 3 and on the panel 21 . The load is attached to the panel by the seat belt 24 .

THE TECHNICAL ADDITION ( FIG. 1, 2, 3) WORKS IN THE FOLLOWING WAY.

The body 2 of the TE is placed on the surface of the trunk 1 . The longitudinal axis 5 of the frame 3 must correspond to the agreed longitudinal axis of the trunk.

The panel 21 is placed on the surface of the bushings 16 , 17 from one zone (e.g. 9 ) or from both zones ( 8 and 9 ). The charge 22 lies on the free surface of the panel 21 . Then the user moves the panel back and forth in the direction of the longitudinal axis 5 by hand . This change of the panel occurs on the surface of slightly rotating bushings.

The technical addition works in these three possible situations:  

1. The working state - when the T.E. on the vacant upper area of the trunk and the cargo around can be put.

2. The working state with fixed cargo - in this Variant, the cargo is also on the upper area of technical addition, but the car is in Move.

3. The state of transport - in this variant the car is on the technical supplement without a load.

Each of three variants has its own special design units. So, in the first variant everyone has to Turn the bushings freely on the roller. The second Variant, the load must be fixed. That is possible, when the panel or sockets (and cargo) are fixed. For the third variant it is rational if the body is disassembled in the blocks.

These three variants are shown in FIGS. 1-6. The variants of the operating state are in Schemes Fig. 1 and Fig. 2. In these variants, the main requirement for the construction is Db / 2 <h1 (1.),
where: Db - the diameter of the socket,
h1 - the height of the roller above the frame.

With this requirement, the bushings will easily wheel and the TE will function effectively ( Fig. 4a). Fig. 3 shows a diagram with a fixed load, which must not move on the surface of the TE and the trunk. For these goals, special technical adjustments are used, which are shown in FIG. 3 as the games

• the adaptation as a grip 23 for fastening the panel to the frame,
• - The adjustment as a seat belt 24 to secure the load with the panel.

Now the descriptions follow the other schemes.

Fig. 4 (a, b) show the schematic diagrams of the free bushing (a) and braking bushing (b). Scheme 4 a corresponds to requirement 1. The braking effect ( 4 b) is achieved by means of the friction effect between the two surfaces (the bushes and the frame). The diameter of the bushing Db is constant and therefore the height of the roller above the frame surface must be reduced (state 13 '). Then the requirement is 2. like h1 <h2.

Fig. 4a indicates the working state and Fig. 4b shows the working state with the panel fixed. In the last variant, the adaptation of the forced braking of the bushing must contain the mechanism for raising or lowering the rollers.

Fig. 5 shows an example of the construction of this mechanism. The roller 12 is mounted in the sleeve 25 , which moves in the sleeve seat 26 . The sleeve 25 can be in one of two states in the upper window 27 or in the lower window 28 . That means the bushings either turn freely or brake.

The forced change mechanism includes a plunger 29 , a lever 30 , a bracket 31, and a pedal 32 . The pressure on the pedal from above - raises the sleeve 25 with the roller 12 ; the pressure from below - lets the sleeve sink with the roller. The number of these mechanisms can be different. To work synchronously with all sockets, they must be connected to one another.

Fig. 6a shows the dismantled technical supplement, which coincides with the third situation in the application of technical supplement. In the scheme, the TE contains four blocks, but it can also be more or less.

Fig. 6b shows the connection block assembly adjustments. The construction of these adaptations can be different (for example, like parts 33 and 33 '), but can be easily dismantled.

The Fig. 7 shows the TE in the transport state. Each block can have a free and elongated end of a certain shape and size. The frames of two neighboring blocks must match and their connection is telescopic. It is rational even if the body of the technical supplement consists of only one part. Then the TE can be installed stationary in the trunk (the diagram is not shown).

Figs. 1, 2 show the basic schemes of the TE, in which the panel placed on rotating bush 21 and can move on their surface.

Fig. 8 and Fig. 9 show different variants of the basic schemes and the basic construction of the TE

Fig. 8 shows the frame containing joints 34 , 35 which are on the inner surfaces of the side walls 4 and the stand 7 . Both joints are at the same height - h3, where h3 <h1 (requirement 3.).

In this scheme, the panel is designed as a figure - the lower part in the joint moves and must with the joint matches; the shell must be used for cargo itself.

The panel 21 is moved by the user's hand.

FIG. 9 shows another variant of FIG. 8. The bushing 16 , 17 move in the joints 34 , 35 . These bushings are mounted on their rollers so that they rotate easily. The free ends of the rollers ( 37 , 38 ) are mounted in the panel 36 , which can be fixed by other technical adjustments - e.g. B. with a rod that is inserted into a hole in the joints.

Fig. 10 shows a scheme which is another variant of the basic schemes ( Fig. 1, 2). The load 21 is moved and placed directly on the socket (the panel is not necessary). It simplifies the construction of the TE, but it complicates the load fixing operations.

Fig. 11 shows the scheme which is a further development of the basic scheme. The body 2 ( FIG. 11a) additionally contains a plateau 39 which is fastened over the frame 3 . The plateau has the shape of a rectangular bracket 40 with windows 41 . The size of the plateau 39 must match the frame size. The surface of the frame 3 has many depressions 42 . The spherical balls 43 are mounted between the frame 3 and the plateau 39 . There is a symmetrical pair that includes a recess 42 (in the frame) and a window 41 (in the plateau). The amount and size of this pair are shown on the invoice. All pairs of "indentation windows" are chess-board-shaped ( Fig. 11b). All beads 43 are mounted in each pair of "well windows". The diameter of the beads must correspond to the height of the plateau and be greater than h4 ( Fig. 11a). In this variant ( Fig. 11) the load can move in any direction because the balls emerge as free rotating bushes.

Fig. 12 shows the adaptation to the forced braking of the beads (example). The adjustment works as a friction brake. The pellets are stopped when the plateau 39 has dropped. Different constructions of the positive brake of the balls are possible. In Figs. 11 and 12, the technical supplement contains a panel which can be moved on the beads. Then the TE can have a joint (as in Fig. 8 or Fig. 9). The previous schemes for moving with the hand of the panel (and the load).

But it is possible and rational if the mechanical Principle is applicable.

Figs. 13-16 show the principle schemes of the TE with the forced mechanical changeover of the panel and the load.

For these schemes you need an electromechanical one Operating mechanism. Different types of operating mecha nism can be used to change the panel.

Fig. 13 shows the mechanism including a reversing electric motor 44 , a reduction gear 45 and control panels 57 . To explain this scheme, we use the term of two types of rollers - the drive shafts 46 , 47 and driven roller (e.g. 50 ). All rolls of the TE are divided into these two groups. The electric motor must be connected to the drive shaft - directly or through a reduction gear. All drive shafts ( 46 , 47 ) are freely mounted in frame 3 , but all of their bushings are fixed.

All driven rollers ( 50 etc.) are fixed and all their bushings are free, which means that they can turn. The drive shaft has z. B. gear 52 , which is fixed and verbun with the other gear 53 is the. The gear 53 is fixedly mounted on the roller 54 of the electric motor 44 . Fig. 13 also shows the cable 55 and the electrical socket 56 because the electric motor uses the electricity from the car's electrical network. All drive shafts are connected to one another. The panel 21 (with the load) moves on the surfaces of all the bushings.

The driven rollers (and bushes) are used as technical aids. The amount of drive shafts depends on the construction of the frame. The special encoder (not shown in Fig. 13) can limit the conversion of the panel be. The user gives a command to work the TE from the control desk 57 , which is stationary or distant.

Fig. 14 shows the forced change of the panel moving in the joints. The electromechanical operating mechanism includes a reversing motor 44 , a train winch 58 , a roller 59 and a rope 60th The winch has a drum (not shown in Fig. 14).

The rope 60 has two branches - the upper and lower, which are attached to the drum. Therefore, if the drum rotates in a certain direction, one branch will unwind and the other branch will unwind. Here, the panel (with or without load) gets a movement in the direction of the roll 59 or away from the roll. Fig. 14 shows the central position of the rope 60 , but other schemes are possible, e.g. B. when the rope is in the joints of the frame.

Fig. 15 shows the schematic of the TE with the electrohydraulic operating mechanism, which includes an electric motor 44 , a hydraulic pump 63 , a hydraulic cylinder 64 and a claw 67 . The cylinder 64 has a system of piston 65 and piston rod 66 . The electric motor 44 works from the car's electrical system and its torque is transferred to the pump 63 . Hydraulic pump 63 is connected to hydraulic cylinder 64 by pressure line 69 . The piston rod 66 is fastened to the panel 21 by the claw 67 . The pump draws oil from the receiving chamber 68 . The oil fills the right part of the cylinder through pressure line 69 and inlet valve 70 . This brings the system forward from the piston - piston rod - panel.

When the oil is injected into the left part of the cylinder, this system moves backwards. The intake valve 70 and exhaust valve 71 is used to regulate the oil direction. The hose protector 72 covers the movable piston rod 66 .

Figure 16 shows the schematic in which each panel ( 21 , 21 ') has its hydraulic operating mechanism ( 64 , 64 '; 66 , 66 '). An analogous scheme fits the rope mechanism - Fig. 14.

Fig. 17 and Fig. 18 show the schemes of the TE for extended trunk - z. B. car that you use for delivery, as well as for microbus and truck. This technical addition can have a hydraulic operating mechanism. The frame 3 of the body 2 has joints 34 , 35 ( 17 a). The sockets are positioned in the joints and are firmly connected to the panels (the principle is similar to the diagram in Fig. 9). The frame can be as a block or it has additional stands and then consists of several blocks. The assembly of this frame can be stationary or non-stationary. In the first variant, the frame is fixed in the trunk. In the second variant, the frame contains special telescopic components 73-78 . One of these elements is basic, e.g. B. 77 and 78 . The TE additionally contains a hydraulic block that works like one in FIG. 15 (not shown in the diagram). In addition, the technical supplement (TE) contains an additional vertical frame 80 ( FIG. 17b) which is attached to the front wall of the trunk.

The cross and intermediate elements (foreheads 81 , 82 and intermediate 83 - FIG. 17 a) are fastened on the horizontal frame 3 . The technical addition works as follows. After command from the control panel 57 , the panel 21 switches to the required zone. One of possible mechanical processes ( Fig. 13-16) can be used to move the panel. When the work with the TE is finished, the telescopic elements of the frame are hydraulically pushed into the base elements 77 , 78 . The base elements then line up vertically on the frame 80 , and the elements 77 , 78 then rise (situation in FIG. 18a). To free all telescopic elements you use a special pneumatic jack 84 , which can be in the set of technical addition. You can use the hydraulic or mechanical method to pull up the base elements.

Result: A new technical means for personal strength car worked out. The technical addition can be applied to all types of cars become. Allows partial or total access Mechanize unloading operations; facilitates and simplifies these operations.
