Description

[Detailed Description of the Invention] The object of this invention is to provide an abrasive paper holder that can firmly hold abrasive paper and can discard used abrasive paper.

Next, the structure of the present invention will be explained according to an embodiment shown in the drawings. The abrasive paper holder holds the abrasive paper 1 at the clamping part 2,
3, a storage section 4 for abrasive paper 1, and a grip section 5.
The clamping parts 2 and 3 are provided at the front and rear of the abrasive paper holder, and are composed of clamping substrates 6 and 7 and holding plates 8 and 9. Two protrusions 10 and 11 are provided on the upper surfaces of the sandwiching substrates 6 and 7, respectively. Fitting holes (not shown) are provided on the inner sides of the presser plates 8 and 9 in protrusions 12 (the front protrusions are not shown) so as to fit into the protrusions 10 and 11. The holding plates 8 and 9 are formed in a U-shape, and locking protrusions 13 and 14 are provided at both ends thereof. The abrasive paper 1 is passed between the sandwiched substrates 6, 7 and the presser plates 8, 9, and the protrusions 10, 11 are inserted through the abrasive paper 1.
The abrasive paper 1 is clamped by fitting it into the fitting hole 9 and simultaneously fitting the locking protrusions 13, 14 of the holding plates 8, 9 into the lower side of the clamping substrates 6, 7.

A storage section 4 for the abrasive paper 1 is provided adjacent to the inside of the front clamping section 2. A slit 15 is provided on the side surface of the storage section 4 on the front clamping section 2 side for pulling out the stored rolled abrasive paper 1. A guard 16 is provided on one side of the storage section 4.

The lower surface 17 of the abrasive paper holder is formed flat. The portion from the front clamping part 2 to the lower surface 17 has a gentle arc shape, but the rear clamping part 3 and the lower surface 17 are connected by a vertical plate 18. Therefore, the ground surface of the abrasive paper 1 is divided into a front arcuate surface, a lower flat surface, and a rear vertical surface, which can be used depending on the purpose and use. That is, the central lower surface is suitable for a wide flat work surface, the rear vertical surface is suitable for a narrow work surface, and the front arcuate surface is suitable for a curved surface.

Since the present invention has the above-mentioned configuration, the tip 19 of the abrasive paper 1 pulled out from the storage section 4 is clamped by the rear clamping part 3, and the abrasive paper 1 is stretched taut and brought into contact with the front clamping part 2. By clamping the contacting portions with the front clamping parts 2, there is an effect that the abrasive paper 1 can be fixed.

When the abrasive surface is worn out and becomes unusable, remove the presser plate 9 of the rear clamping part 3, pull out the tip 19 of the abrasive paper 1 from the protrusion 11, and hold the abrasive paper 1 with the front clamping part 2. By cutting the paper while it is fixed, there is an effect that the used abrasive paper 1 can be discarded.

Furthermore, when using unused abrasive paper 1, remove the presser plate 8 of the front clamping part 2 and place the abrasive paper 1 into the storage part 4.
Another advantage is that the hole in the abrasive paper 1 created by the protrusion 10 of the front clamping part 2 can be used for the protrusion 11 of the rear clamping part 3.

In addition to the above, the present invention can also use rectangular abrasive paper that is not rolled. It is also possible to use abrasive paper in the form of an adhesive tape with adhesive applied to the back side.

The greatest feature of the present invention lies in the means for locking the abrasive paper. That is, the abrasive paper is passed between the sandwiching substrates 6, 7 of the holder and the holding plates 8, 9, which are separate from the holder, and the abrasive paper 1 is pushed through the sharp projections protruding from the sandwiching substrates. It has a structure in which the holding plate is torn and fitted into a fitting hole formed in the holding plate, and at the same time, an inward locking protrusion provided at the lower part of the holding plate is locked to the lower side of the sandwiched substrate. Therefore, even if the holder is moved back and forth many times for polishing, there is no risk of the polishing paper shifting.

Claims (1)

[Scope of utility model registration request] At one end, a means is provided adjacent to the storage section for the rolled abrasive paper 1 and the outside of the storage section 4 for locking the middle part of the abrasive paper 1 pulled out from the storage section 4; An abrasive paper holder that is provided with a means for locking a leading end 19 of the abrasive paper when the abrasive paper 1 pulled out from the storage section 4 passes through the bottom surface of the holder and reaches the other end. The means for locking the abrasive paper is to pass the abrasive paper between the clamping substrates 6, 7 of the holder and the holding plates 8, 9, which are separate from the clamping substrates, and to protrude from the clamping substrates. At the same time, the sharp protrusion is inserted into the fitting hole drilled in the holding plate by piercing the abrasive paper 1, and at the same time, the inward locking protrusion provided at the bottom of the holding plate is inserted into the clamping board. An abrasive paper holder characterized by having a structure that locks on the lower side of the abrasive paper holder.
