Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der in beiliegender Zeichnung dargestellte Mauerbolzen kennzeichnet sich gegenüber dem durch Patent Nr. 93514 geschützten durch Anwendung von nur einem hohlen Keilflügel a mit vorspringender scharfkantiger Nase b und einem cylindrischen vorderen Ansatz d, welcher zur Aufnahme eines Gewindes e dient, sowie ferner durch einen hohlen Keilnagel/", welcher hinten offen und vorn mit angegossener Verschlufsplatte g mit vor das Gewindeloch e passender Bohrung h versehen ist.The wall bolt shown in the accompanying drawing is characterized by the use of only one hollow wedge wing a with a protruding sharp-edged nose b and a cylindrical front shoulder d, which is used to accommodate a thread e , and also by a hollow wedge nail / ", which is open at the back and provided at the front with a cast-on closure plate g with a hole h that fits in front of the threaded hole e.

Diese beiden Theile können aber auch zur Erzielung einer gröfseren Keilwirkung ersterer hinten bis zur Gröfse des Bohrlochdurchmessers keilförmig verstärkt und letzterer, der Keilnagel, umgekehrt keilförmig verjüngt werden, woraus sich ergiebt, dafs nach Einsetzen des ersteren und Unterschieben des Keilnagels unter diesen, ersterer in die Höhe und durch darauf folgendes Anziehen desselben mittels der Schraube i erheblich fester in die Lochwandung gedrückt wird.These two parts can, however, also be reinforced in the form of a wedge at the rear up to the size of the bore hole diameter in order to achieve a greater wedge effect, and the latter, the wedge nail, conversely tapered in a wedge shape, from which it follows that after the former has been inserted and the wedge nail pushed under it, the former in the Height and by subsequent tightening of the same by means of the screw i is pressed considerably more firmly into the wall of the hole.

Diese Anordnung hat gegenüber den bekannten Systemen zunächst das wesentlich Neue aufzuweisen, dafs man bei dünnen bezw. dicken zu befestigenden Gegenständen nicht genöthigt ist, eine lange bezw. kurze Schraube anzuwenden, sondern in fast jedem Falle gestattet, die Eisenschraube so weit in den hohlen Mauerbolzen hineinzuschrauben, bis der Gegenstand fest an der Wand sitzt und somit ein Verkürzen der Schraube ausgeschlossen wird; andererseits ist man auch nicht gezwungen, bei dünnen Gegenständen das Loch in der Mauer tiefer zu schlagen, um den Mauerbolzen tiefer wegen der Schraube einzusetzen. This arrangement initially has that essential compared to the known systems To show new ones, that one with thin resp. thick objects to be fastened is necessary, a long resp. to use a short screw, but is permitted in almost every case, screw the iron screw into the hollow wall bolt until the object is firmly attached to the wall, thus preventing the screw from shortening will; on the other hand, you are not forced to open the hole in the case of thin objects To hit deeper in the wall in order to insert the wall bolt deeper because of the screw.

Claims (1)

Patent-Ansprüche:Patent Claims: Eine Ausführungsform des durch das Patent Nr. 93514 geschützten Mauerbolzens, bei welcher statt zweier oder mehrerer massiver Keilflügel und eines Keilnagels ein hohler .Keilflügel (a) und ein sich diesem anpassender hohler Keilnagel ff) zur Anwendung kommen, von denen der erstere vorn eine Mutter (d) und der letztere eine Deckplatte (g) mit Durchlafsöffnung für einen der Länge des Hohlraumes entsprechenden Schraubenbolzen (i) besitzt.
Bei dem im Anspruch 1 gekennzeichneten Mauerbolzen die keilförmige Verstärkung des hinteren Theiles des Keilflügels (a) in Verbindung mit der Verjüngung des Keilnagels ff], durch welche beim Zusammenziehen beider Theile mittels der Schraube (i) eine gröfsere Keilwirkung erzielt wird.
An embodiment of the wall bolt protected by patent no. 93514, in which instead of two or more solid wedge wings and a wedge nail, a hollow wedge wing (a) and a hollow wedge nail ff) are used, of which the former has a nut at the front (d) and the latter has a cover plate (g) with a passage opening for a screw bolt (i) corresponding to the length of the cavity.
In the case of the wall bolt characterized in claim 1, the wedge-shaped reinforcement of the rear part of the wedge wing (a) in connection with the tapering of the wedge nail ff], through which a greater wedge effect is achieved when both parts are drawn together by means of the screw (i).
