Description

SMART PEGS FOR THE CONSTRUCTION INDUSTRY

TECHNICAU FIEUD OF THE INVENTION

[001] The present invention generally relates to pegs for the construction industry. More particularly, the present invention relates to smart pegs for the construction industry.

BACKGROUND OF THE INVENTION

[002] The construction industry requires coordinates to be marked with physical visible markers, for example, pegs, stakes, nails, paint and the like. Laying out pegs is usually conducted by a team of two men: a global navigation satellite system (GNSS) or total station operator and an assistant who carries the pegs and hammers them in the desired coordinates. Sometimes the pegs are not high enough and replacement and re-staking may be required.

[003] The currently used pegs indicate the height of the upper tip of the peg with respect to the building’s zero level, the height of the upper tip of the peg with respect to the building’s floor level and the like. Some pegs may further include additional information such as construction instructions marked (e.g., printed or hand drawn) on the surface of the peg. Commonly used pegs are marked by writing numbers or letters on the surface of the peg or with a colored ribbon. In some cases, the information is written on the ribbon. These markings are not adjustable or adaptable. Therefore, if an update of the information is required, the old information must be erased, or the ribbon may be replaced.

[004] Furthermore, these pegs lack any indication regarding the distance of ground from the tip of the peg. Such height measurements are used today only in measuring the height of liquids, such as the sea level, lake level, a level of a liquid in a tank and the like.

[005] Therefore, there is a need for smart pegs that may provide adjustable or adaptable information regarding the construction site, for example, the height of the ground at the peg’s location.

DETAILED DESCRIPTION OF EMBODIMENTS THE PRESENT INVENTION

[0020] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0021] A peg according to some embodiments of the invention may be configured to be inserted in the surface (e.g., the surface of a construction site) and adaptively present visual quantitative information related to the tip of the peg and/or construction instructions. Such a peg may include an indicator that may be inspected by the user in order to extract the provided information. As used herein, adaptively present visual quantitative information may include any information related to at least one of: a tip of the peg and construction task instructions. For example, a peg according to some embodiments of the invention may provide the user information regarding: the height of tip of the peg from the building/construction site zero level, instruction at which height a construction task should reach/start (e.g., where to start the floor of a balcony), the height of the surface with respect to the tip of the peg, the absolute altitude, the coordinates at which the peg was inserted, the atmospheric conditions in the vicinity of the peg and the like. In some embodiments, the peg may include at least one extension configured to extend the length of the peg.

[0022] Reference is now made to Fig. 1A which is an illustration of a peg 10 according to some embodiments of the invention. Peg 10 may include a main longitudinal body 20 configured to be inserted into a solid surface 5 and an indicator 30. In some embodiments, indicator 30 may be configured to adaptively present visual quantitative information related to, for example, at least one of: an absolute height of an upper tip 11 of peg 10 (e.g., form the zero level of a building), the distance of upper tip 11 from solid surface 5 and/or the distance of a marker (e.g., marker 38 illustrated in Fig. IB) included in indicator 30 from solid surface 5. In some embodiments, main longitudinal body 20 may be made from any material or a combination of materials that may allow main longitudinal body 20 to be inserted into surface 5. Surface 5 may be surface in a constructions site, for example, soil, rocky ground, concrete and the like. For example, main longitudinal body 20 may include at least one of: a metallic (e.g., steel, cast iron, etc.) portion, a polymeric portion, a wooden portion and the like.

[0023] In some embodiments, indicator 30 may be attached to or marked on main longitudinal body 20. Examples of various indicators 30 and 130 are illustrated and given in Figs. 2-7.

[0024] Reference is now made to Fig. IB which is an illustration of a peg 10 according to some embodiments of the invention. In some embodiments, indicator 30 of peg 10 may include scale notches 31 for marking, for example, the distance of indicator 30 from tip 11 of peg 10 and/or the distance of indicator 30 from the solid surface (e.g., solid surface 5). In some embodiments, scale notches 31 may be marked on at least a portion of main longitudinal body 20, either as protmsions 3 la included in indicator 30a or as grooves 3 lb included in indicator 30b. In some embodiments, indicator 30, 30a and/or 30b may further include a marker 38 (e.g., a ring) illustrated also in Fig. 1C for adaptively marking the quantitative related information, such as the distance information. For example, a user stacking peg 10 may measure a distance between tip 11 and surface 5 and may mark the distance by placing marker 38 at a desired location on indicator 30, 30a or 30b. It should be appreciated that more than one marker may be used on a single peg 10 to mark more than one quantitative information, such as a distance of marker 38 from tip 11 and distance of marker 38’ illustrated in Fig. 1C from ground level. According to some embodiments, two or more sets of scale notches 31 and 31’ may be used, to allow marking two or more different quantitative measures using a single marker 38 as illustrated in Fig. 1C. According to some embodiments, one or more sets of scale notches may be adjustable so that their relative location with respect to at least one other set of indicator notches may be changed along an axis of peg 10 (e.g., longitudinal axis Z of peg 10 in Fig. 1C, substantially orthogonal to surface 5 when peg 10 is in use) as illustrated and discussed with respect to Fig. 2A.

[0025] Reference is now made to Figs. 2A and 2B which are illustrations of pegs 15 having extensions. Peg 15 may include main longitudinal body 20, indicator 30, and an extension 25 configured to extend the length of main longitudinal body 20.

[0033] In some embodiment, indicator 130 may include electronic components, such as, a controller 160, a power supply 170 and a display 180. In some embodiments, at least some of the electronic components of indicator 130 may be included in a printed circuit board (PCB). Controller 160 may include: a processor, a memory and a communication unit (e.g., a wireless communication unit) and may be configured to receive, process, store and send information from and to an external device, for example, a mobile computing device operated by an operator. Power supply 170 may be, for example, a battery, and display 180 may be any display configured to present the visual quantitative information to a user. For example, display 180 may present the coordinates of peg 100 received from the operator. In another example, display 180 may present measurements received from sensor 140, for example, the distance h from sensor 140 to surface 5. In some embodiments, an operator staking the peg may upload (e.g., via the communication unit) the coordinates into controller 160, for example, using an application running on his mobile device. In some embodiments, the coordinates may be received automatically from a positioning sensor (e.g., sensor 140), such as, GPS included in peg 100.

[0034] In some embodiments, sensor 140 may be a height sensor for measuring the distance h of the sensor from solid surface 5, as illustrated. For example, sensor 140 may include a laser beam configured to be directed downward towards surface 5 or may be directed to the surface at a known angle (e.g., an angle formed between the laser beam and a line parallel to the earth gravitation force). In some embodiments, sensor 140 may be configured to measure the distance of various locations around peg 100, by changing the angle and direction of the laser beam. In some embodiments, sensor 140 may include at least one of: a humidity sensor, a thermometer, a barometer, a positioning sensor (e.g., a global position sensor (GPS), a camera and the like.

[0035] In some embodiments, peg 100 (and also pegs 10, 15, 17, 18 and 19) may include a leveler 150. Leveler 150 may provide an operator an assistance in staking the peg perpendicular to the surface or to the horizon.

[0036] In some embodiments, pegs 10, 15, 17 19 and/or 100 may further include a machine- readable element (e.g., a tag, an RFID or a QR code) configured to be read by a reader. The machine-readable element may include identification information related to the peg. The identification information may be associated with information such as the quantitative information related to at least one of: the tip of the peg and construction task instructions and may be presented to the user on an external screen, for example, a screen of a mobile device.

[0037] Some additional aspects of the invention may be related to a device for land marking. The device may include at least one pegs’ application unit; and at least one pegs’ container, for feeding one or more pegs 10, 15, 17 19 and/or 100 to the at least one pegs’ application unit.
