    Support for equipment for measuring environmental parameters, of the type that allow the placement of measuring equipment in three heights and adjust these positions in height. The support incorporates a vertical mast (1) and three support bars (2) placed in horizontal position and at different heights. Said support bars (2) can be moved vertically by means of their respective rack-and-pinion mechanisms (3). The pinion-rack mechanism (3) incorporates a trigger (8) to prevent the displacement of the support bar (2) due to its own weight. The bar-support (2) presents in its entire length a multitude of holes (9) intended for the location of measuring instruments. (Machine-translation by Google Translate, not legally binding)

     SUPPORT AT THREE HEIGHTS FOR ENVIRONMENTAL PARAMETER MEASUREMENT EQUIPMENT SECTOR OF THE TECHNIQUE 5 The present invention is generally framed in the equipment and measurement systems sector. Specifically, the present invention is oriented to the field of measuring environmental parameters. Specifically those parameters that influence the ergonomics of thermal environments. 10 BACKGROUND OF THE INVENTION The thermal sensation that a human being experiences is mainly related to the global thermal equilibrium of his body, which depends, among other factors, on the environmental parameters: air temperature, average radiant temperature, humidity of the air and air speed. The overall thermal sensation of the body in a given environment can be estimated from the measurement of these parameters. There are several international works and standards that present methods for predicting the thermal sensation and the degree of discomfort (thermal dissatisfaction) of people exposed to thermal environments. ISO 7730: 2005 addresses the ergonomics of the thermal environment and describes the calculation of the PMV (estimated average vote) and PPD (estimated percentage of dissatisfied) and local thermal well-being criteria for the evaluation of thermal well-being '. 25 The PMV index takes as input data the air temperature, the average radiant temperature and the relative air velocity among other parameters. The average radiant temperature is the uniform temperature of an imaginary enclosure in which the transfer of radiant heat from the human body is equal to 1 ISO 7730: 2005 -Ergonomics of the thermal environment. Analytical determination and interpretation of thermal well-being by calculating the PMV and PPD indices and local thermal well-being criteria. DESCRIPTIONcarried out in a real non-uniform enclosure; It can be obtained from the balloon temperature and the air temperature. The PPD index is obtained from the value of the PMV. 5 The criteria of local thermal well-being take into account thermal discomfort 10 caused by unwanted local heating or cooling of the body. The ISO 7730 includes asymmetry of the radiant temperature, the air currents, the vertical difference of the air temperature and the presence of cold or hot soils as the most common local discomfort factors. The minimum characteristics of the measuring instruments of the physical quantities that define an environment (air temperature, average radiant temperature, air humidity, air velocity and surface temperature) and the methodology to be carried out in the taking of these measures are specified in international standard ISO 7726: 1998 2. In said standard, a distinction is also made between "homogeneous" and "heterogeneous" environments. Indicating that in heterogeneous environments the physical quantities must be measured in different situations around the subject and more specifically at three heights: at the head level, at the abdomen level and at the ankle level; further differentiating if the subject is 20 in a sitting or standing position. It is necessary to take into account that the height of the head, abdomen and ankle may vary according to the anthropometric values of the different populations of individuals, so that a measuring device intended to take measurements at these three levels should be able to adjust the position in height of the measuring instruments that it incorporates. The present invention is proposed as a solution to the taking of environmental measures at three heights complying with the requirements of ISO 7726: 1998. 2 ISO 7730: 2005 -Ergonomics of the thermal environment. Analytical determination and interpretation of thermal well-being by calculating the PMV and PPD indices and local thermal well-being criteria.EXPLANATION OF THE INVENTION The invention object of the present report refers to a support for measuring equipment of environmental parameters, among those that allow the taking of 5 measurements at three heights. This invention characterizes a special system that allows the installation of a variable number of measuring instruments or sensors and adjusting their height relative to the ground. Thus, the main novelty of the present invention is that sensors on three different heights can be installed on the same support, where the height of each group of sensors is adjustable to the ground and it can be such that a first group is Ankle level of a person, a second group at the level of the abdomen and a third group of sensors at the level of the head, these three levels of height being different depending on the anthropometric characteristics of each population of individuals. The support object of the present invention consists of a mast on which a support bar placed horizontally as a cross can be moved vertically. This support bar is interrupted in its central part 20 by the framework of a rack-and-pinion mechanism that allows its vertical movement along the mast. Inside the frame a pinion is housed, which rotates actuated by means of an appropriate key that is coupled to one of the ends of the pinion shaft. The zipper of said mechanism is integral with the mast and is arranged along its entire length. In this way, by rotating the pinion, it engages on the rack by moving the support bar vertically. To fix the position of this support bar and avoid the fall due to its own weight, the frame has a trigger whose end abuts a pinion of the teeth of the pinion, thus avoiding unwanted rotation of the. same.The function of the support bar is to position and support the various measuring instruments that will allow the measurement of environmental parameters. The support bar has a full length of holes, as housings, for the location of the different measuring instruments. Among 5 other measuring instruments, sensors of: air temperature, balloon temperature, relative humidity, wind speed and ultraviolet rays can be installed. A number of three identical support bars are installed on the mast at 10 different heights, so that each group of sensors of the same support bar will take environmental data at the same level above ground level. The present invention is preferably oriented to its use in indoor enclosures for the measurement of environmental parameters that influence the ergonomics of the thermal environments, but also has application in other fields where it is necessary to take environmental measurements at different heights . BRIEF DESCRIPTION OF THE FIGURES The present invention will be better understood with reference to the following drawings 20 which illustrate preferred embodiments of the invention, provided by way of example, and which should not be construed as limiting the invention in any way. Figure 1 shows a perspective view of the preferred embodiment 25 of the support at three heights for equipment for measuring environmental parameters; Figure 2 shows a detail of the pinion-rack mechanism. PREFERRED EMBODIMENT OF THE INVENTION In view of the foregoing, the present invention relates to a support for equipment for measuring environmental parameters among those whoThey allow the placement of measuring equipment at three heights and adjust these positions in height. It is essentially characterized by incorporating a mast (1) and three equal support bars (2). The mast (7) is fixed to the ground and placed in an upright position. The support bar (2) located horizontally and 5 perpendicular to the mast (1) can be moved vertically along it by means of a rack-and-pinion mechanism (3). The support bar (2) is interrupted in its middle part by the frame (4) of the pinion-rack mechanism (3). This pinion-rack mechanism (3) incorporates a pinion (5), a shaft (6) of the pinion (5), a rack (7) and a trigger (8). The pinion (5), housed inside the frame (4), can be turned actuated from the end of the shaft (6) by means of an appropriate wrench. The zipper (7) is integral with the mast (1) and extends over its entire length. In this way, by rotating the pinion (5), the support bar (2) moves vertically. On the frame (4) articulates a trigger (9) that allows the pinion (5) to be blocked, so that the support bar (2) does not move down due to its own weight. The support bar (2) has a full length of holes (9) that allow the location of measuring instruments. For the placement of measuring instruments at three different heights, a number of three equal support bars 20 (2) are mounted on the mast (1), where the same rack (7) is shared by the three support bars ( 2). It does not alter the essentiality of this invention variations in materials, shape, size and arrangement of the component elements described in a non-limiting manner, this being sufficient to be reproduced by an expert.
