The present invention includes devices and methods that assist in hanging pictures or other things in a desired position on a wall or other similar surface where it is desired to insert two or more mounting nails. Embodiments of the invention include a pair of punch assemblies for inserting the nails provided on a pair of parallel stabilizing bars, although other embodiments may include more than two punch assemblies. Preferred embodiments also include a measuring strip (ruler) between the punch assemblies, and a slidable level and/or a laser. The unique nail insertion mechanism includes a sleeve for receiving a finishing nail, a magnet for holding the nail in place, and a coil spring for maintaining the handle in striking position. After positioning the device on a wall, applying force to each handle collapses the spring and causes a nail to be driven into the wall.

Particularly the present invention will allow a detail and precise contour reading and contour marking on surfaces with sharp angles, angles, curves or any difficult shapes, in particular the present invention pertains generally as a mechanism for patented tool: TOOL, METHOD AND MARKING SYSTEM, Canadian Patent No. 2,625,566, U.S. Pat. No. 8,127,457 B2. As the level of difficulty during the wood flooring/tile installation around curved and/or off angle surfaces arises, and there are limited number of workers who can perform such trade, the MECHANISM FOR TOOL, METHOD AND MARKING SYSTEM, will enable anyone who is familiar with the trade to perform the complicated assignment in a shorter period of time and without waste of material; moreover, it will allow performers to acquire the precise craftsmanship results.

A measurement and installation data indicating apparatus including a distance image sensor that obtains distance image data in a predetermined range, a projector that projects an image on a projection plane in a predetermined range, an inclination data obtaining part that obtains inclination data on a detection optical axis and a projection optical axis relative to a vertical direction, a positional data obtaining part that obtains coordinate data on a present position and a target position, and a terminal controller that generates, based on the coordinate data, a target information image related to the target position and seen from the present position. The terminal controller corrects the target information image to fit to a shape of the projection plane based on the distance image data and the inclination data, and projects the corrected target information image by the projector.

A marking apparatus facilitates blind mounting of an object to a mounting surface in a desired alignment using the object as an alignment template. One end of the apparatus is configured to be affixed to a mounting slot or edge of the object, then the other end used to mark the appropriate supporting fastener location on the mounting surface. The object's mounting slots or edges may be represented by mounting hardware components that are flush with, recessed in, or protruding from the local planar surface of the object. To accommodate a broad variety of mounting conditions and mounting hardware, certain embodiments of the apparatus may include selectively adjustable or interchangeable head adapters, distinct head and retention configurations and/or a hardware relief channel A channel adapter is disclosed for use with embodiments of the apparatus having a hardware relief channel. Embodiments of a slot- securable point marking tool are also disclosed.

Guide systems to facilitate marking a workpiece. The guide systems include a platform and a set of guides. The platform flanks the workpiece on two sides and includes a first member and a second member. The second member is spaced from the first member. The set of guides includes a first guide and a second guide. The first guide has a first profile edge. The second guide is spaced from the first guide and has a second profile edge. A tool may be pressed against the first profile edge or the second profile edge to form a mark on the workpiece corresponding to the first profile edge or the second profile edge, respectively. In some examples, the guide system includes adjustable guides. In other examples, guides are fixed.
