N~IL PLUG
This invention relates to a nail or plug of the type having a plug body adapted in external diameter to a plug bore hole and having a central nail introduction hole.
Such nail plugs have been known for quite some time in the plastic construction art in which a metal nail or plastic nail is used to expand the expansion segments of an expan-sion body against a bore hole wall. It is also known to form such plugs or dowels with blind rivets to permit secur-ing to boards and the like. These nail plugs or dowe]s have the disadvantage that they can only be used in solid build-~ ing materials because with hollow building materials a clamp-; ing action is achieved only in the region of the passage hole and the remainder of the plug projects without effect into the hollow space.
~ satisfactorily firm grip of such nail head plugs in the bore holes is obtained only insofar as they are con-tained in the solid material and when such plugs are used to join boards or panels or the like the length of the plug mus-t be adapted exactly to the width of the boards to be joined.
The use of blind rivets, as employed for example in furni-ture connecting members, also has the disadvantage that blind rivets can be worked only with special -tools and Eur-thermore must also be adapted exactly to the board thickness.

, .
This inven-tion is therefore based on the prohlem of providing a nail plug or dowel which can be us~d both in hollow building materials and in solid building ma-terials or in conjunc-tion with boards or plates. The naiL plug or dowel of this inven-tion uses as an expansion means or member which is pre~erably a nail formed of plastic or ~etal.
The problem set forth above is solved by providing the plug body with projeclions which project beyond its peri-phery and are resilient against compression in the radially inward direction. ~hen radially compressed, these projec-tions exhibit a radially outwardly directed e~panding force which may be intensified by driving a nail into the body.
The provision of projections from the plug surface, in particular projections formed as barbs, results in an out-wardly directed radial spreading which is present before theexpansion means, i.e. the nail, is introduced. The projec-tions and the plug body or its segments which yield radially inwardly on insertion automatically expand outwardly as soon as they come out of the bore hole wall. Since the projections 20 follow each other in short a~ial intervals a firm, resilient support in the a~ial direction can be achieved for any length dimension of the plug hole. This support effect is emphasized by driving-in the nail which not only presses the expansion segments against the plug hole wall but also spreads the pro-25 jections which are ~ree of the wall outwardly so that the plugcannot be removed even by orce oncs the nail is inser-ted. If such a plug is inserted through a bore hole in a hollow build-ing material the resilient segments which project far beyond the periphery of the plug body are first pressed inwardly;
30 that is, the base body becomes smaller. The receiving bore for the expansion means, that is, the nail guide hols, is also made smaller by an amount which corresponds to the amount by which the projections are made smaller. On reaching the end of the bore hole wall, the projec-tions return resiliently 35 and expand behind the boreO If a nail is then driven into L9S~5~
t~le nail guide hole, the force of engagement is increased and the segments can no longer return to their compressed configuration. Since they are aligned opposite -to the with-drawal direction, they ac-t in a manner similar to barbs.
This expansion results in the web or board thickness in engagement with the plug length being of no consequence be-cause an adequate number of projections are always in en-gagement.
A plug or dowel according -to the invention may, however, also be used in combination in solid building materials, being expanded against the bore hole wall over its entire length.
The plug is preferably injection molded from plas-tic but possibly other materials may be used.
Further convenient features of the invention are described below.
Examples of embodiments of the invention will be explained hereinafter with the aid of the drawings, wherein:
Fig. l is a side view of a nail plug made accord-20 ing to the inven-tion with scale-like projections;
Fig. 2 is a view of the plug according to Fig. 1 in the direc-tion of the arrow II;
Fig. 3 is a side view of the plug rotated ~0 with respect to Fig. l;
Fig. 4 shows the plug illustrated in Figs. 1 to 3 inserted in a plug hole of a board with hollow space there-behind; and Fig. 5 shows a plug in a bore hole of a solid wall~
The plug body 10 comprises an a~ially extending 30 central opening or nail guide hole 12. Body 10 is in he form of a sleeve whose outer diameter is determined by the diameter of the pl-ug bore hole. Plug body 10 has projec-tions which project outwardly beyond the diameter of the ~ ~5~L5~
plug bore hole and according to the example of the embodi-ment of Figs. 1 to 3 are made as barb-like projections or scales 14 which point towards -the plug head which i,s pro-vided with a flange 16. Scales 14 yield inwardly, this yielding being permitted as a result of yielding of the nail guide hole 12 and, more particularly, its slots 18 which are interrupted in the center by web 20 and open into an initially closed ~lug foot 22.
Such a plug may be inserted from the left into a bore hole, for example, the hole 24 of a board or panel 26 as shown in Fig. 4, the barb-like projections or scales 14 yielding inwardly. Since no expansion member is initially provided in the plug body, the plug segments (which are formed by the slotting of a body blank) with i-ts projections or scale 14 extending outwardly can be compressed radially inwardly so that easy introduction is ensured. As soon as the projections leave the hole, they expand resiliently out-wardly and bear on the rear side of the panel 26 in each se-quential insertion position. Generally, it will be expedien-t to push the plug completely through the hole as shown in Fig. 4. However, this is no-t absolutely essen-tial if the plug head is to project for some reason to a varying degree from the panel 26. By driving a nail 28 into the nail guide hole 12 , a further outward expansion of the plug segments takes place because the nail diameter is made greater than the diameter o~ the nail guide hole so that when the nail 28 is inserted, a firm grip is guaranteed and release o~ the plug body 10 is avoided.
This anchoring is even ~urther intensified because 30 the slots 18 of the plug body 10 are interrupted at prede-termined intervals by at least one web 20 which serves to ~irmly join the segments together circ-umferentially. As a result, when the nail 28 is driven in, zones are formed in the slit region which expand to a great extent and thereby 35 transfer the expansion force thus preventing rearward move-~ g5~
men-t to a greater extent than would be the case if the plug body were provided with a continuous slot.
Figure 5 shows a plug body 10 inserted into -the bore hole 30 o~ a solid wall 32. On driving in the nail 28, as in known nail plugs, the plug is spread wi-th more pronounced outward expansion force of the displaced pro-jections or scales.
A metallic nail or a plastic nail may be used as nail 28 because nail 28 only fulfills the expansion function and is not subjected to appreciable tensile stress.
It is also possible with this invention to use in conjunction with the plug screws, in particular, nail screws, which is especially expedient if the connection is to be re-leasable.
The embodiment illustrated shows projections in the form of barb-like scales which are axially offset with re-spect to each other but these projections may also have a different form and in their simplest form may take the shape of humps, tongues, knobs or notches. However, a resilient 20 extension of elements projecting a-t an angle inclined with respect to the axial direction -to the plug body is preferred.
To avoid expansion in the region of the plug head, the nail guide hole may preferably be provided witih a larger diameter section 34 in the head portion.
The form of the head of the nails used may be adapted to the form of the plug head so that the head disappears com-pletely or partially in the plug head or plug flange. The nails themselves may be provided over the entire length or over a part of the length of their shank with axial and/or 30 circumferentially extending grooves or ribs which serve as guide means or an-ti-slip means.
