DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows one embodiment of the present invention clasp means in an opened position. The clasp means may be made of a suitably stiff material such as, for example, steel. The embodiment of the present invention shown in FIG. 1 includes a bed plate 10. The securing member 20, to be secured around, for example, a box or luggage, is attached at one end to the bed plate by, for example, a rivet 72 or similar means. First and second bed plate columns 12 and 14 protrude from the surface of the bed plate 10. The first bed plate column 12, is provided with a blocking bolt 22. The second bed plate 14 column provides a point of attachment for an arm 16.

The arm 16 is pivotally attached at one end to the second bed plate column 14 by the arm rivet axle 38. On the surface of the arm 16 are provided a plurality of bearing and guiding surfaces 40. These bearing and guiding surfaces support clamp means 46 for tightening and clamping the securing member 20. Adjacent to the bearing and guiding members, away from the point of attachment of the arm 16 to the second bed plate column, are a second arm profile 44 and then a first arm profile 42.

The bearing and guiding surfaces 40 act as a point of attachment for the securing member clamp 46 by means of a clamp pivot 48, the detail of which is shown in FIG. 6. The clamp includes a profile 51 in which the bearing and guiding surfaces 40 move and to prevent the clamp means 46 from getting out of the bearing and guiding surfaces 40 when the clamp is in a closed position. The clamp means has an entry passage 57 through which the securing member 20 passes. The edge 50 of the entry opening acts as a tightening edge of the clamp means 46. The securing member tightener pivot 56, with the attached tightening surface 52 has ends which extend into and through the slideway 54 formed in the sides of the clamp means 46 as seen in FIG. 5. An exit opening 59 formed in the surface of the clamp facing the arm 16 in the closed position allows the securing member to exit the clamp means 46. A similar opening is formed on the opposite side of the clamp means 46. FIGS. 5 and 6 show the clamp means 46 resting in the bearing and guiding members 40. The multiple bearing and guiding members allow the present invention to achieve a versatility unknown in prior art clasps.

A lever 18 is pivotally connected to the arm 16 at its free end. A stiffening slat 66 is formed on the surface of the lever 18 facing the arm with the clasp means in the closed position. A plurality of protrusions 68 formed on the edges of the stiffening slat 66 engage the surface of the securing member 20.

Locking means for the present invention clasp means is provided by bolt holes 60 and lever cuts 62 formed in the end of the lever 18.

To lock the clasp in a closed position, near the top of the second column are two blocking bolts 24 placed within a bolt sleeve 26. Leading channels 34 protrude out around the bolt passage. Bolt limiters 32 around the opening of the bolt passage prevent blocking bolts 24, from moving too far within the passage. The blocking bolts 24 are joined to each other with a blocking bolt spring 30. This spring also allows the bolts to move as described below in the operation of the present invention. The necks of the blocking bolts 28 will lock the lever 18 in place by passing through the blocking bolt holes 60 as described below.

The free end of the lever is provided with an inclined surface 64 which acts as a surface to which pressure is applied to move the clasp means into the closed position.

Near the end of the lever 18 which is connected to the arm 16, a lip 70 is formed to provide additional locking mechanism for the present invention, the operation of which will be described below in detail.

FIGS. 7 and 8 show the tape 20, one embodiment of the securing member, with cuts along the midle line. FIG. 9 shows the clasp means and securing member at work on the roof of a car. FIG. 10 shows a side view of the application of the clasp means seen in FIG. 9.

In an alternative embodiment, which is not preferable, the profiles 42 and 44 in the arm 16 are eliminated as well as the profile 51 of the clamp means 46 from the pivots 56 of the tightener 52, thereby the eliminating the initial tension on the securing member. However, such change would cause a lesser universality of use.

OPERATION OF THE CLASP MEANS

The present invention clasp in the opened position is to be put on the merchandise that is to be secured with the securing member 20. One end of the securing member is attached to the bedplate 10 with rivet 72. The free end of the securing member 20 is shown entering the clamp 46 through the entry opening 57, girding the tightener 52, wrapping around the pivot 56, and exiting the clamp through the exit opening 59.

By means of a pivot axle 48 the clamp 46 hangs in one of the bearing and guiding surfaces 40. Simultaneously, pivot 56 is situated in the profile 44. Pulling the end of the securing member 20 makes the initial tension in the securing member 20.

By applying pressure to the inclined surface 64 at the edge of the lever 18, this lever, with the arm 16, is moved into the closed position. Simultaneously, the tightener 52 is caused to move out of the profile 44, by the tension from the securing member as the arm 16 moves into the closed position. Then, as the clasp means is moved into the closed position the securing member's tension causes the movement of the pivot axle 56 with the attached tightener 52 in the slideway 54 consequently clamping the securing member between the tightener 52 and the tightening edge 50. The tightener pivot sits in the first arm profile with the clasp means in a closed position and the first tightening edge moves into the second arm profile.

The present invention is analogous to car safety belts, but differs in the shape and construction of the clamp and the use of clamp's and tightener's pivots.

To simplify the construction process of the present invention, adjustment of the tape's initial tension may be eliminated, removing the need for the profiles 42 and 44 and tightener's pivots on the arm 16.

After the arm 16 is moved into the closed position, the securing member, for example, a tape, will be underneath the arm's point of attachment to the bed plate column, thus giving a clamping moment. After creating this moment, it is possible to begin the rotation of the lever 18 in the opposite direction into the closed position. The clamp's locking is based on the fact that the lever 18 with its cuts 62 goes to the neck 28 of the bolts 24. Pressure is applied to the bolts, sliding the bolts into the sleeve 26 as the spring 30 is compressed

When the lever is moved into the fully closed position, the dowel holes 60 of a bit bigger diameter then the bolts 24, are at the same level as the bolts, and the bolts are released with the spring making the bolts pass through the dowel holes locking the clasp means. The bolts movement from the sleeve 26 is controlled by the limiters 32. Accidental unlocking of the clasp means is highly unlikely because it would require an accidental application of force to both bolts simultaneously.

The clamp means is further secured by the lever 18, which, while rotating in the above defined opposite direction, causes a locking lip 70 to move under the pin 22. This locking mechanism also makes it possible to use the clasp itself as a handle.
