Paper roll holder

The innovation "relates to a paper roll holder, the box-shaped housing of which to be attached to the wall Contains mandrel to accommodate multiple rolls side by side and on its front face a removal opening, preferably covered with a flap, next to its one end wall which is movable out of its normal closed position for entering new roles into the housing, wherein the mandrel is attached in a cantilevered manner to only one end wall of the housing and the others next to the removal opening located end wall for ejecting the empty roll tube when pushing a supply roll has a circular opening concentric to this.

In such a box-shaped holder can on the Dorn several paper rolls can be stored next to each other. After using a roll «=? so can the

The next role following the mandrel can be replaced relatively easily in the place of the used role. Until the consumption of one Role, the remaining roles are stored in the interior of the housing secured against dirt or damage and theft. The empty cardboard tube of the just used roll is pushed through the circular opening when a supply roll is pushed in ejected to the outside through one end wall.

The present invention is based on the object of designing a paper roll holder of this type so that it Can be manufactured from plastic as cheaply and simply as possible using the injection molding process «. This task is carried out according to the present Innovation achieved in that the housing essentially consists of two only longitudinally horizontal guides against each other there is displaceable parts, each of which has only one of the two end walls. In this training it is possible to produce the entire housing from only two integral parts in the injection molding process from thermoplastic To manufacture plastic. The two parts are relatively easy to demold and there are none Core shapes required, as the two specified parts have no re-entrant areas or have no surfaces, which include an acute angle.

In further training the innovation are advantageous at the top Edge of the flap on the one hand and on the upper edge of the removal

On the other hand, the opening is semi-cylindrical, axially offset from one another Shells integrally formed, which grip around a hinge axis like a hook. In this way the hinge tabs have succeeded to be molded in one piece onto the relevant parts, these hinge tabs also being easy to remove from the mold and do not require any cores.

It is also advantageous ass the displaceability of the two parts against each other by stops or the like. On one the distance corresponding to the roll width is limited When you enter new roles, the moved part is still held captive on the other part. The postponement preferably takes place in the direction of the dome or vertically to.

Further advantages and features of the inflation result from the description of an embodiment with reference to the drawings. Show it:

The holder 1 has essentially the cross-section of a trough, which is rotated from its normal position by 90 and in the opening of which the rear wall 16 of the housing is inserted. The mandrel 5 is on the right end wall H via a flange 20 attached, on which the paper rolls 10 are pushed. The left roller 10 is in use in the area of Removal opening 2, while the right roller 10 against contamination and damage is safely stored inside the housing.

According to the innovation, the holder consists essentially of only two main parts, the surfaces of which do not have an obtuse angle Include with each other, so that these main parts are easily removed from the mold during injection molding from thermoplastic material can be grounded, with no core required for spraying.

One main part consists essentially of the rear wall and the one end wall 14 formed thereon, which by means of flange 20 holds the mandrel 5 in a cantilevered manner. The flange 20 abuts at the top, bottom and rear with a respective rib 19 which is perpendicular to the rear wall 16 .ixe on the end wall 14. The ribs 19 thus serve as a stiffener and at the same time as

Bracket and Mortageispositiv for the Plansch 20 and the Mandrel 5.

The other main part "consists of the approximately dome-shaped rest Housing walls 21 and the movable end wall 8 with the discharge opening 7. This component 8, 21 is on the stationary Component 14, 16 mounted by means of horizontal guides 22, 23 and horizontally displaceable along these guides. In fact are these guides as ribs 22, 23 extending horizontally in the longitudinal direction and vertically in their width at the top or the lower edge of the rear wall 16 is formed. These guide ribs 22, 23 are of corresponding grooves 24, 25 on the upper or lower edge of the hood-shaped movable component 18, 21 encompassed, namely at the top and at the bottom of the displaceable component 8, 21 two of these grooves 24 each or 25 provided at an axial distance from each other.

In the path of movement of one groove wall 24, at a distance about the width of the roll from the stationary end wall 14, a latching cam 26 is attached, one of which is displaceable Component 18, 21 has sloping curbs. on In this way, the displaceable part 8, 21 can be pushed over the run-up slope of the locking cam 26 during assembly and thus be pushed as far as it will go against the stationary end wall 14, but pushing back is only a matter of time a little more than the width of the paper roll is possible to insert new paper rolls.

The hinge tin articulation of the lid 3 on the housing 21 is Can also be formed without a core on the upper edge of the flap 3 on the one hand and the removal opening 2 on the other hand. That is, half-cylinder heights are offset from one another at these edges Shells 27 to 30 integrally formed, which the hinge axis 31 grip around like a hook (Pig. 5).

On the left! Delimiting surface 4- of the flap 3 is also a small outwardly facing flap 32 is injected, which when pivoting up the flap 3 on the edge 33 of the displaceable Front wall 8 strikes and thus limits the pivoting angle of the flap 3 ″.

Screws 34 that can be pushed through holes in the rear wall 16 are used to fasten the holder to the building wall. Dpbei a horizontally inwardly projecting tab 35 is formed on the displaceable end wall 8, which is inserted in the Position that covers one of the fastening screws 34 so that it is protected from unauthorized dismantling is (Fig. 6). A locking member 36 of the lock 11 engages behind the edge 37 protruding at right angles from the rear wall 16.

To support the free-standing stationary end wall 14, the various hood 21 has a groove on its right edge 3S on (Fit. 7).
