W. Cheney & Son Limited, Birmingham, England, a corporation of Great Britain Filed Feb. 9, 1960, Ser. No. 7,564 8 Claims. (Cl. 292-281) This invention relates to a hasp fitting for luggage and like boxes comprising a body pai-tand a lid part which have a predetermined capacity.

A hasp fitting to which the invention relates is `of that kind comprising an attachment plate and a spring loaded hasp, provided with a staple or stud, hinged to the plate on a fixed axis, so that the hasp can swing under the action of its spring away from the attachment plate, and can be moved against 4itsspring in proximity to the attachment plate, these positions being applicable respectively to the release position and the fastened -positionof the-ha'sp `with respect to. a. co-operative' fastening.

These hasp fittings are mass produced as sheet metal pressings and areas'sem-bled by unskilled labour in order 3,013,832 Patented Dec. 19, 1.9.61

FIG. 3 is a section of FIG. 2 taken on the dotted line 3 3.

FIG. 4 is a section of FIG.. 2 taken on the dotted line 4-4.

As will be observed in the drawing, the hasp fitting comprises an attachment plate 5 formed with a low Y boundary wall 6 and holes 7 for use in fastening the to satisfy public demand for the articles at lan economic price. When assembledon luggage,.the fittings are 'subject. to rough usage and in the release position the soie support `of the hasp is its hinge. This has been found to be a serious disadvantage in practical use because the hasp, which may vary in its length dimension, becomes forced out of alignment withthe attachment plate and as a result the stud or staple becomes disaligned in relation to the fastening member; sometimes the hinges are damaged, twisted or strained so that for one reason or another the hasp fittings become either useless or ineicient.

it is, therefore, most desirable to find, and it is an object of this invention to provide, a simple solution to the problem whereby the risk ofdamage to the hasp by rough usage can be prevented or considerably reduced without increasing the cost of production and assembly.

According to the present invention, a hasp fitting of the kind hereinbefore specified has side walls which project above the outer surface of the attachment plate and which iit Within corresponding side walls of the hasp which is hollow, whereby the side walls on the attachment plate serve as opposing buttress abutments to the corresponding side walls of the hasp and operate to prevent lateral displacement of the hasp whatever its angular position.

According to one form of construction of the invention the attachment plate has confronting side walls projecting above the upper surface of said plate, these Walls being formed by piercing and raising the plate at two positions, whereby two buttress walls are provided which are perpendicular to the plane of said plate. These walls serve as rigid guides which t within corresponding side walls of the lhollow hasp which is pivoted near one end to the said plate. The result is that the side walls of the said plate serve as abutments to the hasp and operate to prevent ylateral Idisplacement thereof whatever v the angular position of the hasp.

In order that the invention may be thoroughly understood, a satisfactory form of construction of hasp fitting according to the invention especially applicable to attache cases and the like luggage is illustrated, by way of example, on the accompanying drawing, in which- FIG. 1 is a perspective view of the hasp fitting illus trated as fastened to a co-operative fastener, the hasp being partly broken away for clarity.

FIG. 2 is an elevation of FIG. 1.

attachment plate, `as by rivets, to a lid 8 of a box of 'predetermined capacity of which the body having -a fastening member 11 is indicated at 9. The attachment plate 5 has confronting side walls 10 -which project above its outer surface 12, the walls 10. being formed by piercing and raising the plate 5 at two spaced positions thereby providing two perpendicular buttress walls 10. A spring loaded hasp 12, provided with a staple or stud 22 to releasably engage the fastener 11, is constructed as a hollow, sheet metal pressing including a body 13 and confronting integral `side walls 14 embracing the walls ,10, the upper part of the walls 14 being formed with alike integral tongues 15 which are hinge-jointed to the attachment plate 5. `The hinge is providedl in a very simple manner by inserting thetongues 15 through alike slots 16 in the attachment plate 5 andbendng the tongues inwardly adjoining the'inner surfaces of the walls to forml a U-shaped hinge 17.I l lt-will be seen that the `confronting side walls 10 of the attachment plate 5 fit within the correspondingrside walls 14 of `the hollow hasp 12, the side walls 10 serving as opposing buttre'ss walls to the walls 14 so that in ordinary use lateral displacement of the hasp relative to its hinge 17 whatever its angular iposition, is resisted by the buttress wall 1t). A torsion spring 18, arranged within the hollow hasp 12, biasses the latter into its position of release away from the attachment plate 5, indicated by the arrow FIG. 3, and

maintains the hinge connection 17; one limb 19 of the spring a-buts against the surface 12 of the attachment plate 5 and the limb 2h abuts against the inner surface of the `body 13. The release position of the hasp 12 under the torque of the spring 18 is limited by the abutment of the hinged end 21 fwith the adjacent part 12 of the attachment plate 5.

The manner in which the staple or stud 22 is secured y ment plate and thus avoid the disadvantages above re- Y ferred to.

What is claimed is:

1. A hasp fitting comprising an attachment member and a hasp member, one of said members havingtwo spaced side face portions facing in opposite directions, each of said side face portions extending between an outer edge portion and an inner edge portion thereof, the other one of said members having two side walls respectively adjacent said side face portions, each of said side walls facing the adjacent side face portion in a respective one of said directions, and a body portion rigidly connecting said side walls; a tongue on each of said side walls, said tongues each having a substantially U-shaped cross section in a plane parallel to said opposite directions and movably receiving a respective one of said inner edge portions within the bight of said U-shape for pivotal movement of said hasp member toward and away 3 from said attachment member; and stop means for limiting said pivotal movement.

2. A hasp fitting as set forth in claim 1, wherein said side face portions are facing away from each other and said body portion is opposite'said outer edge portions, corresponding elements of said body portion and of said attachment member constituting said stop means for limiting pivotal movement of said hasp member toward said attachment member.

3. A hasp fitting as set forth in claim` 1, further cornprising spring means permanently urging said hasp member to move pivotally away from said attachment member.

4. A hasp fitting as set forth in claimV 1, said other member further including a terminal portion extending intermediate said side walls, said tongues defining the pivoting axis of said other member, said terminal portion being radially spaced from said axis, and said stop means including a portion of said one member arranged for abutting cooperation with said terminal portion to limit pivotal movement of said other member relative to said one member.

5. In a hasp fitting, in combination, an attachment plate having an outer face; two side wall members on said outer face and extending outward therefrom in substantially parallel spaced alignment; a hollow hasp member having a body portion and two side portions extending in a direction substantially perpendicular to said body portion and spaced from each other to receive said side wall members therebetween; and a tongue extending from each of said side portions in a direction away from said body portion, said outer face being formed with apertures on either side of each of said wall members, each of said tongues freely passing through one of said apertures on one side of a corresponding wall member in a direction inward of said outer face, and through another one of said apertures on the other side of said corresponding wall member in a direction outward of said face, whereby said hasp member is pivoted to said attachment plate about an axis passing through said tongues.

6. In a hasp fitting as set forth in claim 5, said side wall members being integral with said attachment plate and extending therefrom in a direction substantially perpendicular to said outer face.
