Abstract

A vibration-absorbing, height-adjustable supporting element for machines or implements has a rigid upper part (11) in the shape of an inverted bowl, an elastic, vibration-absorbing lower part (10) whose upper portion extends into the upper part, a pressure plate (20) engaging the top side of the lower part, and a screw (14) extending through a threaded bore (15) in the centre of the upper part and engaging with its end the top side of the pressure plate. A depression (19) in the lower part for receiving the pressure plate a defines a cylindrical wall, which is disposed in the upper part having a conical inner wall member. The combination of resilience and conicity entails that the upper part and the lower part can form a considerable angle with each other so that the supporting element automatically adapts itself to an inclined floor surface.

Description

A vibration-absorbing, height-adjustable supporting element - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
The invention relates to a supporting element of the type defined in the introductory portion of claim 1. The levelling facility makes it possible to compensate for irregularities in or inclinations of the supporting floor surface so that e.g. a machine, which stands on four supporting elements, can be supported in a horizontal position. However, the individual supporting elements in the known embodiments do not lend themselves to resting on an inclined floor surface because the contact faces between the upper part and the lower part are cylindrical, and in some cases also other guide faces, are included which entail that the two parts can practically only move axially with respect to each other. If the floor has a considerable inclination it will then be necessary to secure the screw of the supporting element to the base of the machine in a manner that allows the screw to form an angle with the vertical.
The object of the invention is to provide a supporting element of the type described which allows the upper part and the lower part to form a considerable angle with each other so that, when placed on an inclined floor, the supporting element automatically adapts itself to the angle between the supporting face and the horizontal.
This object is achieved by constructing the supporting element as defined in the characterizing portion of claim 1, since the combination of the conicity of the wall of the upper part and the elastic resilience of the wall member of the lower part permits a sufficiently good contact to be maintained between the two parts along the periphery of the lower part to ensure an effective control in the lateral direction, even though the two parts form a considerable angle with each other.
The construction of the supporting element defined in claim 2 provides for an increase in the resilience of the wall member of the lower part without a corresponding decrease in its laterally stabilizing effect.
An expedient arrangement of the recesses is defined in claim 3.
When the supporting element is constructed as stated in claim 4, provision is made for an increase in the angle which a given conicity of the upper part wall allows the lower part to form with the upper part without elastic deformation.
The invention will be explained more fully below with reference to the drawing, in which
fig. 1 is a vertical section of an embodiment of the supporting element of the invention, and
fig. 2 is a top view of the lower part.
The supporting element shown in the drawing has a lower part 10 made of a relatively hard, elastic material, such as rubber or plastics, and shaped as a thick, substantially circular disc, and an upper part 11 which is made of cast iron and is shaped as an inverted bowl with a base 12 and a wall 13 enclosing the top portion of the lower part 10. A levelling and attachment screw 14 is screwed through a threaded bore 15 in the centre of the base 12 of the upper part and has a square pin 16 at the top. A nut 17 on the top side of the upper part 11 enables the screw 14 to be fixed relative the upper part. A washer 18 is interposed between the nut and the upper part.
The top side of the lower part is formed with a circular depression 19 which accommodates a pressure plate 20, which consists of a hard and strong material, preferably steel, and has a rounded edge circumferentially engaging the wall of the depression.
The pressure plate 20 has in its centre an impression 21, which on the top side forms a recess to receive the end of the screw 14 and on the bottom side forms a bulge extending into a shallow recess 22 in the bottom of the depression 19. The lower portion 23, which forms a base member, of the lower part 10 has a reduced diameter so as to produce a considerable gap between this portion and the wall 13 of the upper part.
As seen best in fig. 2, the outer face of the ring-shaped wall 24, which is inwardly defined by the depression 19 in the lower part, is formed with a plurality, in the shown example six, peripherally spaced recesses 25 which have a shape and extent in the direction of the periphery such that projections 26 shaped as cylinder segments are formed between them. These recesses have moreover an extent in the axial direction from the top side of the lower part such that between the bottom of the recesses and the shoulder face produced by the reduced diameter of the base member 23 is formed an annular flange 27, which touches the outer ends of the projections 26 whose generatrices are parallel with the axis of the lower part.
As appears from fig. 1, the wall 13 of the upper part is conical with a downwardly increasing cross-section so that in the co-axial position of the two parts, in which they are shown in the figure, there is an angle V between the inner face of this wail and the outer generatrices of the projections 26.
The diameter of the cylinder defined by these generatrices is substantially equal to the diameter of the inner wall of the upper part at the top portion of said part, and it will therefore be appreciated that the conicity in connection with the limited axial length of the projections 26 and the flange 27 and the elastic resilience of the wall member 24 of the lower part allows the two parts to form a considerable angle with each other while maintaining a contact between the projections 26 and the wall 13 of the upper part sufficient for the lateral stabilization. This means in practice that when placed on an inclined floor surface the supporting element automatically adapts itself to the given angle of inclination, while the screw 14, which secures the element to a machine base, remains vertical.
The details of the shown and described supporting element can be modified in many ways, which applies e.g. to the shape and spacing of the projections 26, which can even be completely omitted. Also, e.g. the square pin 16 might be replaced by a hand wheel.
