The invention relates to a sanding block with means for plaguing: a sanding blade for hand grinding. _; For sanding objects such as larger surfaces _and the like ^ using sandpaper or sole cloth, the procedure is usually that a sanding sheet is placed around a block with a flat surface on at least one side, which fits well in the hand of the operator with the ends of the sanding belt held by the fingers of the hand.

grinding

sanding blocks can still be provided with gripping grooves, into which the fingers of the hand fit. Such grinding blocks are available in various forms, including grinding blocks a; ü.s. Suggested rubber, which can be opened on one side to enable a sanding sheet to be clamped.

According to the invention it is proposed to use a grinding block to be provided, which consists of two separable block parts, one of which and / or the other part Has means for securing the sanding sheet and for locking the parts together. More advantageous Way exist the means for attaching the sanding sheet to the block part on which the sanding sheet is attached, made of pins, the Pins are arranged near the edge of the sanding block on the side of this block part on which the other Block part sits “In a two-way manner, the other block part is on the side surface with which it sits on the former with pins provided block part sits, equipped with holes in which the pins after joining the block parts fit. In order to facilitate the joining of the two block parts, the Provide guide strips on both block parts on the side surfaces where they are joined.

An exemplary embodiment is shown on the basis of the accompanying drawing of the invention described.

Fig. 1 shows a side view of the grinding block j

Fig. 2 shows the upper part of the sanding block, the Inside of the upper block part is visible;

Fig. 3 shows the lower part of the block, also the Inside of this block part is visible.

The sanding block according to the invention consists of one lower block part 1 on which an upper block part 2 sits. The two bloct parts fit closely together, slots 3 and 4 are provided on the end walls of the sanding block between the two block parts, between which the ends of one around the lower block part 1 can be clamped around the sanding sheet. The one usually made of plastic Sanding block is hollow, so it can be easily inserted into the Hand weighs. Near the end wall of the block part, pins 5,6,7,8 are arranged in the lower block part, as can be seen from Fig. 1: ,, in the upper, likewise hollow block part protrude and "in holes 9 * 10,11,12

fit,

which are formed in the upper block part.

A sanding sheet that is longer than the length of the sanding block but essentially the same width like the sanding block has ^ is on one edge on the Pins 5 and 7 of the lower skewer block, around the end wall of the lower block part near the pins 5 and 7 * the lower surface of the lower block part and the other end wall firmly pulled around and then on pins 6 and 8 on the other edge of the sanding sheet impaled. Then the upper block part is placed on the lower block part 1, and the pins 5 to 8 go into holes 9 to 12 "of the upper part of the block introduced.

To facilitate the joining of the upper and lower block parts 1 and 2, guide strips Γ3 * Γ4.15 * Vq ₃ 13a, l4a, 15a, l6a are provided on the inner surfaces of the block parts 1 and 2. To lock the block parts 1 and 2, elastic clamping strips 17j18 are used, which are fastened to the lower block part. These elastic clamping strips have a groove which cooperates with strips and grooves 19 * 20 of the upper part.

The lower part of the block is designed in such a way that the edges connecting the end faces with the lower face

this

this block part are formed, are designed differently, one edge is sharp, while the other edge is rounded.
