ABSTRACT OF THE DISCLOSURE
The plug consists of a body comprising an aperture for the accommodation of a threaded element, and a spreader. In order to impede the transmission of noise between a threaded element to be screwed into the plug and the structural part into which the said plug is inserted, the body is embedded in a sleeve made of a vibration-damping material.

Description
The invention rclates to a plug for securing a threaded element in a hole in a structural part, the said plug having a body comprising an aperture for the accommodation of a threaded element and a spreader.
Many plugs of this kind are known. Such plugs are made either of metal or of plastic, and are used to accommodate elements which may have a wood-screw or a machine thread. The disadvantage of these plugs, however, is that they conduct noise from a part connected by the threaded element to the structur-al part housing the plug.
It is the purpo~e of this invcntion to provide a plug of the foregoing type which substantially avoids the transfer of noise. -According to the invention, there is provided a plug for securing a threaded element in a hole in a structural part, said plug having a body compris-ing an aperture fcr the accommodation of the threaded element as well as a radially outwardly dcformable ~preader part for wedging in the hole when the threaded element is screwed into the body aperture, wherein a sleeve substantially completely surrounds the body with the exception of the aperture for the accom-modation of the threaded element and the s~leeve is made of rubber, the Shore hardness of which is between 70 and 75.
It was found that embedding the body of the plug in a vibration-damping material substantially reduces the transfer of noise.
The vibration-damping effect of the plug may be improved by providing the vibration-damping material in the form of a sleeve namely a radical flange at the base-end of the body.
If the spreader is located in the central part of the plug, the body is surrounded by the sleeve at its tip end. If, however, khe spreader is located at the tip of the body (the end which is inser~ed into the structure), then the embodiment wherein the sleeve has an aperture at the tip end of the body is ~,, -1-~ 3~
advantageous, since this design impedes the funotloning of the spreader the least.
The Shore hardness of the rubbGr sleeve is preferably between 65 and 70.
The connection betw-een the body and the sleeve may be improved by pro-viding projections which are tapered in such a manner that subsequent insertion of a body into a sleeve made of vibration-damping material is possible, and withdrawal is impeded. An embodiment wherein the slee~e is moulded onto the body is particularly s~atisfactory for preventing rotation of the sleeve and body.
An ombodiment wherein the body comprises at the tip end a threaded part connected to a guide at the base and by sp~eader webs comprising buckling grooves is intended for elements having an embodiment wherein the body com-prises a guide at the basc and with adjacent spreader elements is intended for wood-screw threads.
Examples of the plug according to the invention are explained herein-after in conjunction with the accompanying drawing in which:
Figure 1 shows a plug with a body, the spreader being located centrally.
The plug is shown in longitudinal section. The lower half of the figure shows the body in longitudinal section.
Figu~e 2 shows a plug having a ~ody with spreaders. The plug is shown in longitudinal ~ection. The lower half of the figure shows the body in long-itudinal section.
The plug illustrated in Figure 1 includes~ a body 1 having an aper~ure for the accommodation of a threaded element, not shown. The tip-end of the said body has a part 2 with an internal thread 3. ~t the base end ~the end into which the threaded element is inserted), the body has a

This part also acts as a spreader, to which end it includes elements 13, which are integral with guide part 14, at the base-end of the body. Projections 15 in the form of ribs are arranged on the outer surfaces of elements 13.
These projections ensure a positive connection with sleeve 16 surrounding the said body.

The sleeves of the plugs illustrated are made of a vibration-damping material. Rubber provides particularly satisfactory results.
Satisfactory damping properties are obtained with rubber having a Shore hardness of about 60 to 75, preferably between 65 and 70. The bodies and sleeves may be made separately and then assembled. However, it is particularly advantageous to mould the sleeve onto the body, since this produces a particularly strong joint therebetween.
