  • this object is attained by providing a frame structure having a plurality of inwardly projecting studs on the inner surface of two or more of the opposite side walls and arranged in two opposing series with the studs in one series offset or staggered peripherally of the frame with respect to the studs in the other series.
  • the studs in both series are of progressively increasing height inwardly from the respective opposite edges of the frame side walls and terminate at their inner ends in angularly disposed faces which cooperate and define therebetween a groove-like space or recess for the reception of a ventilating grille or like member that is mounted in the frame.
  • Fig. 1 is a top plan view of a frame structure made in accordance with the present invention.
  • Fig. 2 is a sectional View on line 22 of Fig. 1;
  • Fig. 3 illustrates a grille body in a preliminary posi tion before being mounted in the frame
  • Fig. 4 illustrates the grille body in its final mounted position
  • Fig. 5 shows one of the spring fastening elements illustrated in Fig. 3.
  • reference numerals 1a, 1b, 1c and 1d designate the four side walls of the frame structure, the respective side walls la, and 1b, 1d being disposed in oppositely related parallel relation to provide a frame structure of quadrilateral configuration.
  • the side walls of the frame structure are States atent till projected inwardly substantially at right angles to the wall and form with the portions of adjacent side walls an inturned corner 6 directed diagonally of the frame as shown in Fig. 1 of the drawing.
  • an ear which lies in the median plane of the frame and is designated by the reference numerals 7, 12, 13 and 14, respectively. These ears are each provided with an opening ii therethrough for fastening means to secure the frame in position.
  • Cast integrally with the frame structure and projecting inwardly thereof from the side walls la, lb, 10 and lid are two series of studs each comprising a plurality of studs arranged so that the studs in one series are peripherally staggered or offset with respect to the studs of the other series.
  • the studs of one series are designated by the reference numerals 2, 4, 9, ll, 2', 4, 9' and 11 and the studs of the other series are designated by the reference numerals 3, 3', and 10, ill, respectively.
  • the studs in the respective series are of progressively increasing height inwardly from the opposite edges of the side walls of the frame and terminate at their inner ends,
  • the frame structure is designed entirely symmetrically so that one and the same frame structure can be used for the horizontal or vertical mounting of a ventilating grille or like element.
  • a ventila ing grille body 20 may be mounted as shown in Figs. 3 and 4.
  • the front surface of the grille body is designated 21 and the body portion extending from the surface is designated 23.
  • the grille body is adapted to be mounted in the frame in a wall 24 having an outer surface 25 and an inner surface 26.
  • a wall 24 having an outer surface 25 and an inner surface 26.
  • the walls la, 15, 1c, and 1d of the frame closely lit the wall opening.
  • the grille body Zil is mounted in the frame by means of spring elements.
  • the spring elements are designated 27 and 27a and are pivotally mounted on the body at points 29 and 3d, the opposite ends of the spring elements 27 and 27a engaged in the groove 17 as indicated.
  • each spring element consists of a wire symmetrically doubly bent at the points 31, 32, and 33, 34 respectively.
  • the intermediate legs are designated 35, 3'5, 37, and 3d, and the central leg is designated 39.
  • the opposite ends 41, 41 of each spring element are axially aligned and are adapted to be inserted in corresponding ears at the point 29 for the spring element 27 and the point 30 for the spring element 23.
  • the operation of the device is as follows: As shown in Fig. 3, the extending body portion 23 of the grille body 21 with the outstanding spring elements 27, 28 directed against the groove 17 in the sides of the opening, is inserted into the opening. The body is then pressed downwardly as indicated by the arrows A, A, A. Inward displacement of the grille element 21 causes the spring elements 27 and 28 to pass an unstable position when the points 29 and 30 are in the same plane as the groove 17. At this point, the spring elements reach their maximum compression. As soon as this unstable position has been passed during the inward movement towards the inner surface 26, the spring elements tend to revert to their original form. This means, as shown in Fig. 4, that the spring elements tend to secure their flange 22 of the body flush against the fiat outer surface 25 of the wall.
  • a quadrangular frame structure for mounting ventilating grilles and the like comprising oppositely related spaced parallel side walls, two series of studs integral with the frame side walls and projecting inwardly of the frame from the inner surfaces of at least two of said side Walls, each series of said studs comprising studs arranged in spaced relation along the interior of said two opposite side walls of the frame with the studs of one series staggered with respect to the studs of the other series, and the studs of both series being of progressively increasing height and thickness inwardly form the respective opposite edges of the side walls and terminating at their inner ends substantially at the median plane of the frame in angularly disposed faces which cooperate to define between the two series of studs a recess for reception of the fastening elements of a ventilating grille.
  • a quadrangular frame structure for mounting ventilating grilles and the like comprising oppositely related spaced parallel side walls having their opposite end portions at the four corners of the frame projected inwardly substantially perpendicular to the respective side walls and forming with the inwardly projected end portions of the adjacent side walls an inturned corner, said inturned corners being operable to engage the end portions of the body of the ventilating grille inserted in said frame, two series of studs integral with the frame side walls and projecting inwardly of the frame form the inner surfaces of at least two of said side walls, each series of said studs comprising studs arranged in spaced relation along the interior of said two opposite side walls of the frame with the studs of one series staggered with respect to the studs of the other series, and the studs of both series being of progressively increasing height and thickness inwardly form the respective opposite edges of the side walls and terminating at their inner ends substantially at the median plane of the frame in angularly disposed faces which cooperate to define between the two series of studs a reces
