Abstract

There is provided a grindstone stand that can stably hold a grindstone having various shapes and dimensions with a single grindstone stand without damaging the grindstone. An assembly of a grooved sliding square member, a square member fastener, and a bolt is set on a through long groove rail that is provided so as to penetrate from the upper surface to the lower surface in the longitudinal direction at the front and rear ends of the upper surface of a rectangular base. The mechanism is flexible enough to play a role of sliding and rotating along the through long groove rail. The grindstone can be fixed at a predetermined position by this fixed-direction slide and a flexible fastener, and can be easily detached. [Selection] Figure 1

Description

  The present invention relates to a grindstone base in which a long groove having a bolt width and thickness is provided on a flat top surface of a rectangle, and two pairs of fasteners for freely moving and holding the grindstone are provided.

  General artificial whetstones and natural whetstones are large, medium, small, or variable, and the shape and dimensions of the whetstone are not constant, and it has been impossible to install whetstones of various shapes on the same whetstone base. For this reason, the number of grinding wheel bases is the same as the number of grinding wheels.

  In the case of sandwiching a grindstone, rust caused by secular change became difficult to attach to the iron screw tightening. In addition, when the grindstone is mounted, if the fastener is thicker than the grindstone thickness or if there is a metal protrusion, the thin grindstone cannot be handled and the blade may be hit and damaged.

  Published Utility Model Publication No. 2-27861

  Each grindstone has a variety of properties, and a grindstone stand corresponding to each grindstone is required, and there is a burden in carrying and storing the grindstone. Therefore, regardless of the length or shape of the grindstone, it is possible to easily install the grindstone of various shapes to a predetermined position with one grindstone stand, it is difficult to remove and attach due to the corrosion of the metal fittings, and the fastener on the upper surface of the grindstone stand It is intended to solve the uncomfortable feeling of workability due to the protruding metal fittings.

  The present invention provides a rectangular base with a flat top surface, a through-long groove rail with a bolt width and thickness penetrating from the top surface to the bottom surface in the longitudinal direction toward the center of the top surface in the longitudinal direction, and sliding the bolt onto the through-long groove rail. Together with the role, it serves as a foundation that allows free setting of the grindstone.

  In the through long groove rail, there are provided two independent groove sliding corners slidable in the front-rear direction, each of which is attached to the groove sliding corner member, and comprises a square member fastener that holds a grindstone that slides on the upper surface of the base. It had a pair of assemblies. The bolts of the aggregate project to the lower surface of the through long groove rail to install a thumbscrew, slide the aggregate, place a grindstone at a predetermined position between square brackets, screw in the thumbscrew, and hold the grindstone And fixed. This grindstone can be freely slid and rotated horizontally on the upper surface of the rectangular base regardless of the predetermined position of the grindstone, which makes it possible to hold various shapes of grindstones, and also increases the sense of stability in use. It becomes a grindstone stand and solves the conventional problems.

  As described above, the grindstone base of the present invention is such that each of the two aggregates fixes the grindstone by sliding and rotating, and is fixed by sliding and rotating. There is a fixing method in which the grindstone is placed at a predetermined position on the base, each assembly is moved and sandwiched, and a bolt protruding at the bottom of the rectangular base is tightened with a thumbscrew to complete the setting. The two square bar clamps that hold the grindstone can be fixed to this grindstone stand by making it possible to fix the grindstone regardless of the length of the grindstone, regardless of the metric size. It became. In addition, the hardware related to the wheel head is made of a stainless steel material and maintains long-term performance.

  It is an upper slope figure showing one example of a whetstone stand of the present invention.   It is a lower part slope figure which similarly shows one Example.   It is an upper top view similarly.   Similarly, it is a lower plan view.   It is also a grindstone and a side view.   It is a grindstone and sectional drawing.

  Since the arrangement is basically made every time the aggregate of the square bracket that holds the flat grinding stone on the rectangular base and the bolt made of stainless steel is slid, stable sliding on the groove of the long groove rail can be performed constantly. . At the front and rear end centers in the longitudinal direction of the long groove rail, a penetrating long groove rail penetrating from the upper surface of the rectangular base to the lower surface of the base is provided, and the bolt can be slid within the through long groove rail.

  A grindstone can be arranged at a predetermined position by horizontally moving an assembly in which a pair of the square bar fastener, the groove sliding square bar and the stainless steel bolt is combined. At one of the above positions, either one is tightened and fixed with a thumbscrew at the bottom of the base, and the other assembly is nipped and fixed, and the operation is completed. In addition, the flat upper portion of the square member fastener for sandwiching and fixing the grindstone described above is designed such that the blade is not hit and damaged by embedding the head of the bolt. Further, since the square bar fastener is made to be rotatable, it can be pinched and fixed even when it reaches a deformed whetstone such as a natural whetstone, and can be easily removed by loosening one thumbscrew at the time of detachment.

Hereinafter, an embodiment will be described with reference to the accompanying drawings. The base 1 is made of a wood material and a resin material.
A pair of square brackets 5 and 5 and stainless steel bolts 6 and 6 for sandwiching and fixing the groove sliding corners 4 and 4 to the long groove rail 2 on the upper surface of the base 1 and the penetrating long groove rail 3 on the lower part of the base 1. If two such aggregates are installed, the aggregates 4, 5, and 6 are in a sliding state. The grindstone a is placed at a predetermined position on the flat surface of the upper surface of the base 1, and either one of the pair of aggregates 4, 5, 6 is fastened with washers 7, 7 at the bottom of the base 1 and wing screws 8, 8. The assembly 4, 5, 6 is sandwiched in accordance with the grindstone “a”, and is clamped and tightened by the above operation to be fixedly attached. To remove the grindstone a, the grindstone a can be quickly removed by loosening one of the stainless wing screws 8 and 8 described above. One embodiment of the present invention has this configuration, and can easily and reliably perform the holding mechanism.

  By making the square bar fasteners 5 and 5 rotatable, for example, even if the edge of the natural grindstone is deformed and the both ends are not parallel, the square bar fasteners 5 and 5 correspond to the edge of the grindstone. And can be fixed tightly.
