Paint roller

The present invention relates to a color V roller, which is used to apply a layer of paint or similar clothing to an object to protect and / or decorate this item.

A previously known paint roller consists of one piece, e.g. a relatively thick steel wire, which, starting from a horizontal part on which the paint roller is mounted, ends freely on one side of the roller and on the other side is first bent at right angles onto the head surface of the paint roller , then bent inwards at an angle of - 45 with respect to this head surface and finally bent back into a position Γ perpendicular to the longitudinal direction of the inking roller, with on

the latter can be attached to a handle.

A disadvantage of this known paint roller is that it is shipped in bulk from the factory to wholesale and from Wholesale to retail trade requires a lot of space because the protruding part is both in storage and in transport The handle cannot be removed and the paint roller therefore requires relatively large packaging. in which a large part of the available space cannot be used.

Another disadvantage of the known paint roller is that the paint roller is difficult to replace with a new paint roller can be.

Furthermore, this known paint roller has the disadvantage that the paint roller bears mainly at one end, i.e. one end is pressed harder or harder on the surface to be processed than at the other end, because the horizontal part on which the inking roller is mounted merges into the handle at that end.

The present invention has for its object to provide a paint roller that has the disadvantages of the known Doesn't have paint roller.

This object is achieved in that the paint roller consists of a single or loose handle or handle and a single or loose holder for the paint roller, and that the holder and the handle can be connected to one another. It is thereby achieved that the holder and the handle loose from each other, can be introduced into a package, the package dimensions are mainly determined by the dimensions of the Hal- ( "'ters for the ink roller, because the handle is now parallel to the holder can be inserted into the packaging.

In a preferred embodiment of the paint roller According to the invention, the holder is on the side facing away from the roller with a fastening sleeve with a truncated cone Provided bore, with the mounting sleeve provided in the middle of the length of the holder is, and the handle with a truncated-cone-shaped

Pin is provided whose apex angle is substantially equal to that of the bore. In this embodiment of the paint roller, the handle can be very · ■; , easily attached to the holder, while also applying the - " inking roller evenly over its full length

; the surface to be processed can be pressed,

ι 'because the handle is in the middle of the length of the holder for

f the inking roller has been placed in the holder.

In a particularly expedient embodiment of the color

(' rollers according to the invention, the hole in the fastening

f _t supply sleeve at its end facing away from the handle

If provided with a protruding shoulder, and the tenon is

i'l on its mating end with at least one

\ - resilient lip, which at its free end has a

:, has a protruding collar that when the handle is mounted

\ rests on the shoulder. According to the invention is included

the pin with two diametrically opposed, resilient lips, the outer circumferential plane in the same Surface like the outer circumferential plane of the truncated-conical Pin is provided. As a result, the handle is firmly connected to the holder, which is a fixed connection but is only realized by the user of the paint roller.

According to another characteristic of the invention is that Inking roller removably mounted on the holder. For this purpose, the holder for the ink roller consists of a channel, those at both ends with a transverse one End wall is provided with a bore for receiving the stub axle of the inking roller.

To facilitate the assembly and disassembly of the inking roller, the end walls of the trough-shaped holder are in Lengthways direction of the gutter resiliently movable, the length of the color orphan, between the inner ends of the axle journals measured, is at least equal to the smallest inner distance between the end walls of the holder, when the inking roller is not mounted in the holder.

Preferably each end wall of the rinnenformigen holder on the outside with a recess whose depth is mainly the thickness of the end wall of the same, and provided at Γ the inner side opposite the recess with a projection, the shape and thickness of the mold or the depth of the recess equal to are. This projection and the associated recess on the end walls of the holder have the purpose of keeping the resilient mobility of the end walls within certain limits and to give the end walls a certain rigidity. This prevents the holder from flexing lengthways in use, which could cause the pins to slide out of the bores in the end walls. \

Finally, according to the invention, both the handle and the holder are made in one piece, in particular by injection molding. This allows the handle and the holder of the paint roller according to the invention to be considerable lighter than those of the known paint roller, saving up to a weight 50% can be achieved. This makes the worker considerably easier with the new paint roller according to the invention

The invention is based on the drawing with an exemplary embodiment of the paint roller explained further.

Fig. 3 is a side view of the paint roller with the f handle firmly attached to the holder;

Fig. 4 is a longitudinal section, on a larger scale, of the connection between the holder and the handle in fig the mounted position.

The paint roller according to the invention consists of a single or loose holder 1 and a single or loose Handle or stem 2, both made in one piece by injection molding from a suitable plastic are. The holder 1 consists of a channel 4 with a bottom 5 and at an angle of e.g. -45 the bottom 5 associated side walls 6, while the channel 4 is closed at the ends by transversely arranged end walls 7. In order to save material and to keep the weight as low as possible, the handle 2 is hollow on the inside. In an extension piece or a stem can be inserted into the cavity. The handle 2 has an octagonal Cross-section and is provided at its free ends with two diametrically opposed slots 3, with which the paint roller can be hung on a hook. The wall thickness of the holder 1 and the handle 2 is about 2mm. In the trough-shaped holder 1 is

an inking roller 8 mounted on its cylindrical surface with a fabric of natural or synthetic Fibers with a high or low pile, foam plastic or other clothing can be; all of this depends on the type of paint to be processed and the surface to be processed.

The holder 1 and the handle 2 are by means of a coupling member 9 on the holder 1 and a complementary coupling member 10 on the handle 2 verjj together bindable. The coupling member 9 on the holder 1 is on the

Q. the inking roller 8 facing away from the bottom 5 in the

Arranged in the middle of the length of the holder 1. The coupling member 9 consists of a fastening sleeve 11 with a truncated conical bore 12, which has its largest diameter at the free end of the sleeve 11 and which is provided at the other end with a circumferential shoulder. In the vicinity of the free end of the fastening sleeve 11, two diametrically opposite recesses 14 are provided in the wall of the bore 12. The coupling member 10 of the handle 2 consists of a truncated conical pin 15, the conical apex angle of which is mainly equal to that of the bore 12 is C and 3. At the free ends of the pin 15 are

two diametrically opposed, resilient lips 16 are provided, the outer peripheral surface of which is in the same area how the outer circumferential surface of the truncated-conical pin 15 lies. The lips 16 are at their free ends provided with a collar 17 which lies on the shoulder 13 when the handle 2 is mounted on the holder 1.

The resilient lips 16 are when the handle is assembled because the wall of the bore 12 against the collar 17
