The inventive tractor 1, in particular a garden tractor has an open seat 2 driver, which may be partially closed by a flexible folding feet 3, and contains a fabric cloth 4, fixed on the basis of the tractor behind the driver's seat, rear leg and stretch the arc 12 articulated crank levers and the front arc 13 for detachable mounting tissue. 5 C. p. F.-ly, 8 ill.

The invention relates to tractors, in particular for the garden tractor with an open seat of the tractor, i.e. not closed cabin.

Known tractor with an open seat for the driver, including a flexible awning fabric panel forming a cover over the driver's seat, front arc for mounting an awning installed on the chassis of the tractor, and part of keeping back part of the tent.

The disadvantages of this device is the inability to fold the tent and inconvenience of use.

The basis of the invention is the technical problem of creating a tractor of this type with a simple, suitable and attractive coating rector has a flexible folding top and a fabric cover, comprising vertical and horizontal walls, bounding back and upper part of the seat of the tractor, respectively, with a vertical wall secured at its lower edge to the design of the tractor, the rear arc with the crankshaft richani, which can be folded or lower position or in a vertical position to support and tension the vertical wall fabric cover, front mounting arc for fastening and tensioning the horizontal wall fabric cover, and quick release means for securing a fabric cover to the front arc.

Thanks to this design, the upper body can be easily and quickly raised and lowered manually (or using the drive servomechanisms. In the raised position, the coating provides effective protection seat of the tractor from rain and sun, but leaves it open on the sides of the tractor for easy access and better visibility. In the lowered condition of the flexible top and back arc connected in a compact, folds flat behind the driver's seat.

Mounting the arc also performs a useful protective function in case of overturning of the tractor, and should preferably be secured to the design of the tractor with the possibility of stalnye wall fabric coverings are respectively a partial side walls to better protect the tractor operator.

Back arc has an upper U-shaped element rigidly attached to the inner side of the fabric cover, the first lower pair of levers pivotally connected at one end to opposite sides of the frame of the tractor and the other end to the lower ends of the legs of the U-shaped element, a second lower pair of levers pivotally attached to the frame of the tractor and to the shoulders is a U-shaped element, respectively, behind and above the corresponding joints of the first levers and bounding with them articulated chetyrehzvennoj, and a couple of quick interactive elements for closing the joints between the first arms and shoulders a U-shaped element, when the rear arc nahoditsya in the raised position.

Means for securing a fabric cover to the front arc contain many fingers that are installed on the hard edge of the horizontal wall fabric cover and incoming from above into the corresponding recesses in the front arc, and bond rigidly attached to the rigid end wall, passing under the front arch and secured by a buckle located on the rear of the horizontal wall near the rear of the arc.

Communication can also be successfully used to hold the top when C is ctor with a flexible soft-top General view of Fig. 2 a longitudinal section a-a in Fig.1; Fig.3 is the same, with the top at an intermediate stage of its descent, and Fig.4 is the same, with a folded roof; Fig.5 is a view along arrow B in Fig.2; Fig.6 three-dimensional image of part of the top; Fig.7 three-dimensional image of the rear fastening top, partial cut, and Fig.8 cross-section b-b In Fig.7.

Garden tractor 1 has a seat 2 of the driver, which is normally open and may be partially closed by a flexible folding tent 3.

Tent 3 contains the panel 4 of waterproof fabric, which in the raised position (Fig.1 and 2) is a vertical protective (rear) wall 5 located behind the seat 2 of the driver and a horizontal top wall 6 extending above the driver in the form of the roof. The rear wall 5 has two transparent Windows 7 for rear view, with walls 5 and 6 are respectively a short extension cords, which can be folded down, making the respective partial side walls.

The base of the back wall 5 is rigidly attached to the frame of the tractor. It is evident from Fig.7 and 8 it is seen that the rear part of the seat 2 of the tractor operator has the form a C-shaped element 8 attached to the frame of the tractor 1 and forming two interior is replays to the rear of the element 8 by means of rivets or other similar fastening elements 11.

A fabric cover supported in raised position on the rear arch 12 with folding crank levers and the front arc 13. The rear arc (Fig. 6) consists of the upper U-shaped element 14, the lateral shoulders 15 which have the lower ends of the two connector 16, each of which has a respective first transverse finger 17 for coupling the end of the first lever 18.

The lower end of each lever 18 pivotally connected by transverse finger 19 with suitable support housing 20 mounted on the side of the tractor closer to the rear of the seat 2 of the driver.

Each connector 16 on his finger 17 is another cross-finger 21 to swivel the end of the second lever 22, the lower end of which is pivotally attached to the corresponding support body 20 via pin 23 located behind the finger 19 and above. Two levers 22 are slightly bent.

Each pair of levers 18, 22 together with the corresponding connectors 16 and a support body 20 to form an articulated chetyrehzvennoj, by means of which the rear arch 12 may be folded from the raised position (Fig.1 and 2) in the fully lowered position (Fig.4), passing through the intermediate position shown in Fig. 3. Folding osuser> Back arc locked in the raised condition by a pair of hooks 24 on the upper portions of the levers 18, and a pair of swivel levers 25 on the lower ends of the connectors 16 and cooperating with the hooks 24.

The u-shaped element 14 in the rear arc 12 is rigidly attached to the fabric panel 4 in its inner side and top loops 26, 27. When the rear arch 12 is in the raised position, the rear wall 5 fabric cloth 4 is stretched and supported in the area of its connection with the upper wall 6.

Perdana arc 13 is U-shaped and attached to the sides of the tractor ahead of the seat 2 of the tractor. In addition to fixing the upper wall 6 a fabric cloth 4 specified anterior arch 13 protects the tractor in case of overturning of the tractor. This arc can be attached to the tractor either rigidly or pivotally, to be able to be lowered to the front of the tractor when omitted fabric cloth 4.

The clip 28 (Fig.5) front arc 13 in its upper part has a lot of holes 29 with a vertical axis; these openings are intended to interact with corresponding fingers 30, available on the hard end of the element 31 attached to the front This rigid element 31 has the form, allowing it to be partially wrapped around the cage 28, and is used for interaction communication 32 (Fig.2) with buckle 33 mounted on the underside of the upper wall 6 of about 34 at the interface between the top and rear walls.

When the awning is raised 3, which corresponds to the vertical position of the rear arc 12, the fingers 30 are in the holes 29 of the front arc 13 and the connection 32 is held under the yoke 28 and secured with tensioning buckle 33.

In order to lower the awning 3 from this position, it is necessary to release the connection 32 of the buckle 33 and lift the front edge of the vertical wall 5, to bring the fingers 30 of the holes 29.

Now you can fold or roll up the upper wall 6 to its junction with the rear wall 5. If the lever 25 is released from the hooks 24, the rear arch 12 may be folded in this way (Fig.3) until it is fully down position (Fig. 4). During lowering of the rear arc 12 of the rear wall 5 fabric cloth 4 is formed as a harmonic between the U-shaped element 14 in the rear arc 12 and the element 8. As can be seen in Fig.4, in this position of folds formed by the folded fabric cloth 4 and lowered the rear arch 12, is securely attached to the tractor using the same connection 32, which is attached pikirayi is its raised position in the reverse sequence of operations.

Although in the described and illustrated example of the invention transactions relating to the raising and lowering of the awning 3, are made by hand, the rear arch 12 may be lowered and raised and fabric cloth 4 can be minimized and maximized, for example, driven by servo-mechanisms. For this purpose a special drive from the motor bracket can be adapted for automatic engagement of the front side wall 6 with a front arch 13.
