Definitions

• This invention relates to a fastener intended for mounting objects on plates of the type that comprises two mutually movable tongues, a first one of which is pressable against the bottom side of a plate and the second one is pressable against the top side of the plate.
• Previously known fasteners of the above generally mentioned kind are used for mounting, for- instance, table lamps, pencil-sharpeners document holders and the like, on an edge of a table top.
• one of the tongues consists of a horizontal, upper branch on a U-shaped clamp
• the second tongue consists of a rotatable washer on the upper end of a screw, which is arranged in a threaded hole in the lower, horizontal branch of the U-clamp.
• auxiliary table is previously known for such folding tables which are found in passenger crafts or vehicles, more precisely on the back side of the back of individual passenger armchairs.
• the object of the above-mentioned auxiliary table is to increase the storage surface of the passenger in connection with consumption of food or drink, preferably by receiving drinking-glasses or the like.
• the auxiliary table is elongate and has at opposite ends thereof turnable arms, which are articulatedly connected with the auxiliary table and with two fasteners, which are intended to be fastened on opposite side edges of the ordinary, back-carried table.
• the fasteners include two vertically spaced-apart tongues intended to clutch the table edges.
• a U-shaped bracket is included in the fasteners in which the lower hinge of the turning arms is hinged.
• the fastener shown in MR 65 371 is suitable so far that the same is compact and smoothly sur ⁇ rounds the edge of the table.
• Fig 4 is a front view showing the two parts in a composed state .
• 1 generally designates a first part in which a first tongue 2 is included intended to be pressed against the bottom side of a table top (not shown)
• 3 designates a second part having a second tongue 4 intended to be pressed against the top side of the table top.
• two male-like, elastic resilient fingers 5, 5' are included having first serrations 6. Said fingers extend perpendicularly to the tongue 2 and are at the bottom spaced-apart by means of a cylindrical recess 7 with the purpose of facilitating bending of the fingers, more precisely in the direction inwards, towards each other.
• the part 1 is in its entirety made of plastic of such a nature that the fingers, at least partly as a consequence of inherent elasticity of the plastic, may be bent with the upper ends inwards, towards each other from the state shown in fig 1, in which said ends are maximally distanced from each other.
• Each individual finger 5, 5' includes on one hand a web 8, and on the other hand a bead 9 on which the serration 6 is formed. More precisely, the serrations on the two fingers 5, 5' are turned outwards, from each other. In this connection, it should be pointed out that the serrations 6 in the drawings have been illustrated with an exaggerated teeth depth for the sake of clarity. In practice, the serrations may be formed with very shallow teeth or projections.
• the webs 8 are larger than the beads 9, not only so far that the same are wider than the beads, but also so far that the same are longer than the beads.
• elongate recesses 10 are formed for a tool, the function of which is described closer below.
• a seat designated 11 is included, which is delimited by two second serrations 12 turned towards each other.
• the serrations 12 are formed on flanges 13 which together with a rear wall 14 define a through gap 15 (see fig 3) .
• the gap 15 mouths in an upper opening 16 through which the recesses 10 are accessed from above.
• a horizontal bottom wall 17 extends that at the outer wall thereof transforms into a vertical, second wall 18.
• the walls 14, 17, 18 form a cross-section-wise U-shaped bracket.
• holes 19 are recessed for a pivot pin (not shown) of a turnable arm of the type that is included in the auxiliary table according to MR 65 371.
• a semi-cylindrical flute 20 is formed, which facilitates bending of the tongue 4.
• the two tongues 2, 4 are advantageously initially inclined in the way that is shown in fig 3. More precisely, the tongues converge somewhat in the backward direction from the U-bracket . In this way, the tongues may be resiliently pressed against the top and bottom sides of the table top.
• the described fastener is compact and joins smoothly to the edge portion of the table top in question without other projecting parts than the bracket walls 17, 18 (which are located beside the table surface) .
• a pliers tool may be used having two branches which are inserted into the recesses 10 and are pressed together during bending of the two fingers 5, 5' inwards towards each other. In this way, the male serrations 6 are released from the engagement with the female serrations 12.
• the invention is not solely restricted to the embodiment described above and shown in the drawings.
• the invention may also be applied for mounting of other objects than turnable arms of auxiliary tables.
• the design of the fastener device may be varied in multiple ways within the scope of subsequent claims.
• the fastener may also be used on other plates than table tops .
