Description

A STRINGLINE BLOCK FIELD OF INVENTION The present invention relates to a stringline block. The present invention has particular but not exclusive application for a stringline block for laying bricks. The patent specification describes this use but it is by way of example only and the invention is not limited to this use. BACKGROUND OF THE INVENTION Stringlines are used to assist bricklayers when laying bricks. Typically a stringline is tied between two reference points to create a straight line. Normally there are a couple of ways for a bricklayer to tie a stringline. Typically each of the two ends of a stringline is tied to a separate column when laying bricks. One problem within that is it takes effort for a bricklayer to tie the ends of the stringline to the column. Another problem within that is it is difficult for a bricklayer to keep the stringline at a same level around the column. The stringline may also be accidentally displaced and it may not be easily to detect if such a displacement has occurred. A further problem with tying a stringline to a column is that a single stringline may not provide enough accuracy for some brick laying jobs. OBJECT OF THE INVENTION It is an object of the present invention to overcome or at least alleviate one or more of the above mentioned problems with laying bricks and / or provide the consumer with a useful or commercial choice.

The second wall 44 has two second guides 52 in the form of roll pins. One of the second guides 52 is located on an upper surface 54 of the second wall 44. The other second guide 52 is located on a lower surface (not shown) of the second wall 44 The third wall 46 has four third guides 56,58 in the form of roll pins. Two of the third guides 56,58 are located at the upper surface 59 of the third wall 46. The other two third guides 56,58 are located at the lower surface (no shown) of the third wall 46. The string block 40 further has a protrusion 60 attached to an edge 53 of the second wall 44. The protrusion 60 is perpendicular to the second wall 44 and extrudes outward the second wall 44. The protrusion 60 is rectangular in shape. The protrusion 60 has a same height and thickness with the first wall 42, second wall 44 and third wall 46. The protrusion 60 has four fourth guides 62 in the form of roll pins. Two of the fourth guides 62 are located at the upper surface 64 of the protrusion 60. The other two fourth guides 62 are located at the lower surface (not shown) of the protrusion 60.
