which are needed for mounting the actual holder onto( the wall. Such known devices either have a lower locking mechanism operating by locking of a spring member and a holding projection or an unaccessible retaining spring. Furthermore, many of the known holders for paper rolls can be removed without applying any force.

It is the principal object of the invention to provide a tamper-proof holder for paper rolls from which the paper roll can only be removedrwithout destruction of the holder when the paper roll has been substantially used up. l

Another object of this invention is to provide a tamperproof holder for paper rolls which is simple in both construction and operation in that it has no auxiliary locking or holding means or any secret unlocking buttons or the i like.

A further object of this invention is to provide a base plate being fixed to the wall in such a manner that it can only be removed when the mechanism holding the paper roll is in the open position.

Other objects and advantages of the invention will be apparent from the following description in conjunction with the accompanying drawings, in which like numerals refer to like parts lthroughout the several figures, and

wherein FIGURE 1 is an elevational view partly in section of the preferred embodiment of the holder for paper rolls;

FIGURE 2 is a lateral cross-section of the holder taken along the line A-B of FIGURE l;

FIGURE 3 is a bottom view of a longitudinal section of the holder;

FIGURE 4 is an enlarged view of the shaft of the holder in its disengagementposition;

FIGURE 5 is a cross-section through the portion shown in FIGURE 4 along the line C-D.

Referring now to the drawings more in particular,

FIGURE l shows the preferred embodiment of the invention where the holder is fixed to the wall by screws which cannot be removed when a paper roll is in place.

If the holder is merely glued against thewall it comprises the following parts: a mounting member 1 provided with a gummed planar surface, a supporting bracket 2 and a securing member 3. In case of the preferred vembodiment where the mounting is attached to the wall by screws, special attachment means are required. Y

As shown in FIGURES l',` 2, and 3, Ythe mounting 1 i is provided with a continuous bore 6 having a likewise continuous groove 7 andan enlargement 3. On the left side of the bore 6 is inserted. by means of a shaft 15 the supporting lbracket 2, 'the second leg of whichconsists of a vsupport member for receiving a paper roll which supv port ends ina recessed projection 1u. ,Y On the right side of the mounting 1 is insertedV by means of a shaft 16 the securingV member 3, the second leg of which consists of United States Patent O "ce a projecting portion or member 11 being equal in shape Patented Nov. 3, 1964 to the support member 9 and provided with an opening 12V for receiving and holding the recessed projection 10 of the support 9. Due to the arrangement of the groove l 7 and the recess 8 as well as of

holding projections

13 and 14 being positioned at the ends of the

shafts

15 and 16, the supporting bracket 2 and the securing member 3 can be inserted only if the bracket is not fixed to the wall, whereby the connection is rendered unreleasable in a mounted support. This connection allows also for a horizontal moving range of the securingrnember 3 parallel with the mounting surfacein an axial direction, in addition 4to the semicircular pivoting movement beginning at the mounting surface. Besides theradial pivoting movement, the supporting bracket 2 can also perform a minimum disengaging movement for which point x (FIGURE l) serves as a rotary point. However, this movement is possible only in the position in which the shaft 15, which has a non-circular shape, .itsinto the groove 7. g i

The

holding projections

13 and 14 aty the ends of the

shafts

15 and 16, respectively, are in engagement with the walls formed between the continuous groove 7 and its enlargement 8. While the engaging side 17 of the support 9 of the supporting bracket 2 engages in any stage of the radial pivoting movement with the opening 12 of the safety member 3 after having overcome the bending stress of the supporting bracket, this engagement can be released only in one predetermined position of the` pivoting movement. This point is so chosen that the paper roll inserted into the support 9 has no longer any pilfering value when it reaches said point. FIGURE 5 shows which relative position between shaft 15 and groove Y .tailed recess 1S positioned at the rear side of the mounting 1. The groundplate 4 is provided with two countersunk bores 19 for receiving fastening screws and with an angularly joined flap 20 (FIGURE 2) for the lowerV closing of the recess 8. The connection between the groundplate 4 and the mounting 1 is secured by means of a pin 5. This pin 5 can be inserted only when the bracket is open, and it cannot be easily removed, whereby the fastening screws remain inaccessible.

It is obvious that the tamper-proof holders for paper rolls according to this invention allow exchanging of paper .rolls before they are completely consumed. Holders where an exchange of rolls is only possible after a roll has been used up are not suitable for` administration buildings, hotels, restaurants, hospitals and the like where the exchange of rolls isl generally performed on an inspection tour. This type of handling requires that there should be a possibility for exchanging nearly consumed rolls also. L

However, theholder according to the invention is in particular devised for the above-mentioned buildings and consequently rnust be adapted to the described requirements. In the known devices it is further more easily possible to pilferthe roll, for instance by introducing a springl needle Vbetween the case of the roll and the release pressure point/thus actuating the latter one, as well as makingthedevice useless by deforming the springor breaking itoff or bytaking off non-secured auxiliary means and other parts.

It `will betunderstood that this invention is susceptible to further modication and, accordingly, it is desired Vto comprehend suchmodications within this inventionas `may fall within thelscopeof the appended claims.

I claim:

1. A safety holder for a roll of paper comprising an elongated mounting member having a at planar surface on one side thereof, and a bore extending longitudinally therethrough,l a supporting bracket and a securing member carried by said mounting member and extending therefrom at right angles thereto, means at one end of said supporting bracket mounting said supporting bracket in oneend ofsaid bore for pivotal movement in a plane at .right angles to said bore, means at one end of said securing member mounting said securing member in the other end of said bore for pivotal movement in a plane at right angles to said bore, and for sliding movement axially of said bore in a direction away from said supporting bracket, an integral roll supporting member extending at the other end of said supporting bracket, toward said securing member `andterminating in an integral latch member, an integral roll supporting member extending 'from the. other end of the securing member toward said supporting bracket and terminating in a latch receiving means, which receives said latch member and secures said roll supporting members together, said first named means also mounting said supporting bracket for pivotal movement toward said securing 4member sufciently to unlatch said latch means only when said supporting bracket is extending in a plane substantially parallel to said flat planar surface.

2. The invention as defined in claim l, wherein said rst named means comprises a shaft having a portion rectangular in cross section and said bore having a rectangular groove for receiving said rectangular portion only during the pivoting of said supporting bracket toward said securing member.
