In order to solve the above problems, the present invention provides a vehicle elevating and lowering tilting device which generally includes a bearer member, a rigid support member, and a tilting device.

〔Example〕

As shown in FIG. 1, the lifting and tilting device of the present invention includes an elongated base shaft 21, which has a flat bottom surface 23 for installation on a flat surface. The bottom surface 23 may be processed into an uneven shape to prevent sliding on the ground, or may be provided with a material having a high coefficient of friction.

For this purpose, rubber or similar synthetic surface materials are conceivable. The cross section of the basic shaft may easily adopt other shapes or may be quadrilateral. The base jars 71-21 have a proximal end 25 and an opposite distal end 27.

A pair of upright vertical ears 29 are attached to the base end 25.

The two ears are long plates with a quadrilateral cross section. At each 14°, there is a hole 31 which is dimensioned to receive a pivot bolt 33.
is provided. The ears 29 are arranged separated from each other on opposite sides 35 of the shaft 21. Due to this separation, the two ears form a channel through which the lifting shaft 37 is inserted.

The shaft 37 is an elongated shaft having a quadrilateral cross section over its entire length.

Four flat sides 38 are formed by the outside of the shaft 37 . The shaft 37 has three proximal ends and a distal end/11.

The three proximal ends fit into the channels between the two ears. proximal end 3
The two shafts 37 are formed with elongated channels. The channel is dimensioned to slidably receive and hold the pivot bolt 13. Pol I 43 has a head that first passes through ear 29A, then through the channel of shirt h37, and then through ear 29B. After that, the nut is screwed into the port I. Its attachment removably maintains its functionality so that the pivot pin defines the pivot center of shafts 21 and 37.

Shaft 37 defines a second channel 43 extending across the width of the shaft. As shown in FIGS. 1 and 1, the channel 43 is provided at a position slightly apart from the three proximal ends. Channel 43 has a long chain 45
A holding device such as the above is inserted. The chain 45 is a support member 47
It has two free ends that can be threaded around it. The two free ends of the chain are removably connected by a connecting means 50, such as a key. The chain 4 is formed by an endless chain 45 formed by joining the free ends of 21!1i+.
5 is linked to the support member 47. This interaction minimizes and prevents movement of the device in directions parallel to the four longitudinal axes of shaft 21. Other arrangements for linking shaft 37 to support 47 are also contemplated.

One of them is a hook or a plurality of hooks attached to the shirt l-37, which can be released by the support body 47 and a hand operation. This linking device is the shaft 37
Similarly, it can be attached to the shirt 1 at 21.

An abutting I-rolly 51 is slidably attached to the shaft 37. As shown in FIGS. 1, 2, and 4, the trolley 51 has an inverted U shape and is composed of three integrated flat plates 50. The trolley 51 forms a U-shaped channel 53, which is open downwardly. Channel 53 is dimensioned to slidably receive shaft 37 so that trolley 51 slides along the length of shaft 37. One of the side wall plates 50, specifically the plate 55, has a threaded hole 56 into which the closing bolt 5 is inserted.

The plate 63 includes a U-shaped structure 66 forming a channel 67. The channels 67 are arranged transversely to the longitudinal axis 66 of the shirt 137. More specifically, U-shaped structure 66 and channel 67 are arranged at right angles to longitudinal axis 69. Other +1.1 configurations include channel 67 as axis 6.
Place parallel to 9.

The structure 66 serves as an isometric surface between the lifting shaft 37 and the undercarriage or vehicle bottom to be raised or lowered.

The shape of the structure is therefore suitable to ensure non-sliding contact in relation to the undercarriage. The width or depth 71 of the channel 67 is dimensioned to slidably receive a cross section of a vehicle frame or undercarriage 72. Alternatively, the user may insert filler insert I into channel 67.
