Abstract

Device for the improvement and reinforcement of square joints of pieces finished in miter, essentially characterized in that it is constituted by a flat horizontal piece, with the possibility of turning around the minor axis of symmetry located in its same plane, and dividing the device into two parts, on each of which is placed a solid piece whose vertical section is a right isosceles triangle, both being joined by its vertex opposite the corresponding right angle, and coinciding with a point of the axis of rotation. Said parts are provided, respectively and along their entire length, with a projection of sagittal section, and a recess of the suitable shape, and placed in the appropriate arrangement, to achieve the accommodation of the first in the second, constituting a machi-hembrado system, each one of the two pieces equipped with the above mentioned entrate and salient, is extended along its upper edge, in a rectangular ledge in the same direction as the corresponding lower horizontal half-plane of the two in which it divides the axis of rotation to the flat piece that is base of the device, and located obliquely and upwards with respect to it, forming an angle of little magnitude with the horizontal plane. With this, impregnated said rectangular protrusions of the relevant adhesive, as well as the two protruding halves of the base of the device, will be introduced, the projection and half of the base corresponding to each side, in the corresponding opening of each of the two pieces whose square attachment is desired, to achieve the bonding, which will be facilitated by virtue of the existing inclination between each rectangular projection and the half base of its same side, since when they become parallel when the introduction is made in said pieces, they will press on the internal faces of the openings that are provided with those in which they have been introduced. Once the above operation has been carried out, one of the halves of the device will be rotated, with respect to the other, around the axis of rotation, an angle of ninety degrees, with which, the pieces of triangular section mentioned above will be perfectly joined, in virtue of the machi-hembrado system of which they are endowed, with what, and given the unión of the device to the pieces whose unión to squad pursues, will obtain, also, the mentioned and perfect unión of these last ones, being able, according to their dimensions, use one or several devices such as the one in question, which will be introduced as indicated in the opening or openings that will be provided for this purpose.
