6 Claims. Cl. 190-58) This invention relates to luggage hardware. More particularly, the present invention is concerned with post loops for articles of luggage such, for instance, as suitcases, briefcases, handbags and thelike.
Heretofore in the use of post loops, the attaching portions of the posts either were inserted in pre-formed openings in the part of the luggage to which the post was to be attached or were forced therethrough. For economy of manufacture, the openings usually were not pre-formed where the post was attached to a wall it could penetrate, e.g., a wooden wall. In such cases, however, the attachment of the posts sometimes split the wall and spoiled the luggage. This was particularly true where a shook wall was utilized, consisting of only a single thickness of wood; but even where plywood was employed, the bottom ply often splintered, so the connection between the post and luggage was weakened.
Another difficulty encountered with present-day posts and the methods of attaching the same was that the tips of the posts frayed badly when curled to form the head that secured the post to the wall of the luggage. This often caused an insecure connection or resulted in a worn spot in the luggage lining where material rubbed against the rough head.
It is a main object of the present invention to provide a post of the character described the attaching portion of which when forced through a luggage Wall does not tend to split or splinter the wall.
-It is another object of the present invention to provide a post of the character described the attaching portion of which can be forced through a wall with less effort than heretofore and therefore causes less operator fatigue when a foot press is used.
It is another object of the present invention to provide a post of the character described which is inexpensive and simple to'fabricate and mount by mass production methods.
It is another object of the present invention to provide a post of the character described which is more easily and effectively held in place on the luggage.
It is another object of the present invention to provide a post of the character described the attaching portion of which when headed for attachment to the wooden wall of the luggage does not fray. V
It is another object of the present invention to provide a post of the character described which does not tend to pushsplinters out from a wooden wall when forced therethrough, whereby the mounting dies are maintained comparatively free from debris without the necessity for constant cleaning.
Other objects of the invention in part will be obvious and in part will be pointed out hereinafter.
The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts which will be exemplified in the articles hereinof which will be indicated in the appended claims.

Referring now in detail to the drawings, and more particularly to Figs. 1-4, the reference numeral 20 de-' notes a suitcase having a handle 22 secured to its top by post loops 24 constructed and mounted in accordance with the present invention. Each post loop comprises two metal posts 26, a bar 28 and an escutcheon plate 30.
A post includes an upper handle mounting portion 32 and an attaching shank 34. The latter has a smaller diameter than the former and is separated therefrom by a perpendicular shoulder 36. The upper, i.e. handle mount ing, portion of one post includes a blind opening 38 extending perpendicularly to the vertical axis of the post. Said opening faces and is registered with a through opening 40 in the upper portion of the other post. Thebar 28 is received in these openings and permanently "secured inplace, as by force fitting its knurled head 42 into the opening 40.
The posts and escutcheon plate are pre-a ssembled in any convenient manner. As illustrated in the drawings, this can be accomplished by providing openings 43 in the escutcheon plate to receive the attaching shanks of the posts and making the region 44 of each shank just below the shoulder slightly larger in diameter than the rest of,
the shank. The posts are inserted into the escutcheon plate until the shoulder 36 abuts the upper surface there: of. Then region 4.4 is peened against the undersurface of the escutcheon plate, forming a holding flange 45.
The attaching shank of each post is formed with the axial blind bore 46 running from the free bottom end of" The pre-assembled post loops are mounted on a Wooden top wall 48 of a shook box having no pre-formed open ings in the manner and with the apparatus described'in detail hereinafter. Generally, the mounting is asfifollows: An elongated metal bearing plate 50 is located below the shook wall. The said plate has openings 54 through which the ends of the attaching shanks of a post. loop are snugly insertable. The shanks are forced through;
the wooden shook wall to which the posts'are to be attached. 1 Said shanks are long enough to extend com i deeply .to receive fully the wooden plug 52 (Fig. 11) and thus avoid the imposition of bursting pressure on the tubular attaching shank. V 2
In the modified form' of the invention shown in Fig.
13, the ends 55 of'th'e tubular shanks are provided with an internal chamfer. The modified form of the invention shown in Fig. 14 has an internal and external chamfer at the-ei1ds561of the tubular shanks. These foims of posts are mounted in the same manner as the first-described form.
- The difierent types of chamfers for the tubular shanks are preferably, although not necessarily, employed under diiferent conditions. For example, the attaching shank 34 with an external chamfer requires the least efiort for penetration and therefore is the easiest to use from the operators point of view. However, it exerts a spreading effect on edges of the opening formed in the wooden wall and therefore desirably is not used on extremely narrow walls such as are found, for instance, in an attach case. On the other hand the attaching shank with an internally chamfered end 55 does not create a spreading stress and can, accordingly, be used on narrow walls and very close to an edge without any danger of splitting the wood. Moreover, said internally cham'fered shank forms a particularly clean exit opening when forced through wood. The plug 52 cut by such an internally chamfered shank has a diameter considerably in excess of the diameter of the blind bore 46 so that the plug must be diametrically compressed as it is forced into the shank. This creates no particular problem with soft woods; but dense or hard woods sometimes exert so much pressure on the inside walls of a tubular attaching shank that a split or crack is developed therein. Thus, the shank 34 desirably is used Where the handle is to be fastened in other than a narrow wall or where the shook box is of dense or hard wood, and the shank with the internally chamfered end 55 will be employed on narrow walls or close to an edge, provided that the wood will not tend to split the shank.
The shank with both an internally and externally chamfered end 56 incorporates to a substantial degree the ad vantages of both the other shanks and to some extent their disadvantages as well. I have found that the double chamfered shank secures the best results for overall run of the mill operations whereall types of shook boxes are used so that this is the type of shank that I prefer to employ unless conditions, such as very narrow walls, or a very close-to-the-edge mounting, or very dense hard woods, are encountered. f
Referring now in detail to Figs. -12, a method and apparatus are provided for mounting post loops of the character described on a wall of a piece of luggage. The apparatus includes a press 57- having an upper holder 58 and an anvil,60, each comprising an elongated metal block. A stud 62 is secured to and projects from the topsurface of the holder block, said stud being fastened in a socket in a vertically reciprocable ram 64 located above the anvil.
A notch 66 is provided near each end of the holder 58 in the bottom thereof, each notch opening onto the front ofthe holder; The notches are large enough and deep enough'to freely and wholly contain the ends 68 of the luggage handle 22. Each'notch is provided with a 'pair of circular slots 72, the slots of each pair being disposed on opposite sides of the associatednotch and the axes of theslots being contained in a vertical plane parallel to the longitudinal axis of the holder. Each slot has a roof 74 located a distance from the bottom surface of the holder 58 somewhat less than the length of the upper handle mounting portion 32 of the post 26. The reason for this will become apparent hereinafter.
Each slot communicates with its associated notch by a side opening 75, and the slots of each pair are spaced from each other a distance such that the slots will receive 1 the posts of a pre-as'semb eld post loop. The notches are spaced apart a distance snflicient for them to receive the ends of a given handle. The sizes of the notches and slots, the distances between the slots of each pair, and the distances between the notches can, of course, be varied from holder to holder for. diiferentsized handles and/ or post loops.
The slot of each notch nearer an end of the holder 58 includes a linear passageway 76 extending horizontally to the back of the holder. The shank of a headed pin 77 is slidable in each passageway, said pin being of such length that when the head 80 thereof abuts the back of holder 58, the other end projects into the slot. A leaf spring 81 has an end disposed over each pinhead 80, said spring comprising a flat strip of resilient steel suitably held to 1 the back of the holder 58, as by a bolt 82 screwed in a tapped opening 84 in the holder. pin into the slot. This best may be seen in Fig. 8.
' The anvil 60 supports an elongated flat horizontal levelling plate 88'. The bottom of the anvil is provided with '1. a central tapped opening 90 adapted to receive an externally threaded shaft 92 on which the anvil is carried. As may be seen in Fig. 5, the levelling plate 88 is mounted on the anvil by vertical support rods 94 suitably secured to the plate and slidably received in vertical through openings 96 near each end of the anvil. Each opening 96 includes a narrow upper portion 98 and a larger lower portion 100, said portions being separated from each other by an annular step 102. A plunger 104, snugly slidable in the portion 100 but too large to fit into 1 the portion 98, is fastened to the end of each rod below of and a width just slightly greater than the width of a bearing plate 50. A pair of circular vertical through openings 108 is provided in the channel near each end thereof. Said openings are of larger diameter than openings 54 of a bearing plate 50, and the pairs of openings 108 are adapted to be coaxially aligned with said openings 54. Nubs 109 project from the base of the channel to aid in aligning the bearing plates with said pairs of openings. The distance between the openings of each pair and the distance between the pairs themselves is such that the pairs of openings 108 in the levelling plate are aligned with the pairs of slots 72 in the notches of the holder.
A die 110 is located in each opening 108, each die constituting the top surface of a circular column 111 mounted on the'anvil and extending into said opening 108. The dies and columns are snugly receivable in said openings. Each die includes a rounded central protuberance 112 projecting slightly above the base of the channel 107 when the levelling plate 88 is at its uppermost position. The protuberance is surrounded by a shallow concave annular depression 114 which in turn is surrounded by an upwardly projecting peripheral flange 116 of slightly less height than the protuberance. The protuberances are adapted to fit into the mouths of the blind bores at the free ends of the attaching shanks 34, and the depressions are of such diameter as to receive said ends themselves.
The spring biases the The apparatus operates as follows: The holder is vertically reciprocable over the anvil which is mounted in a fixed position. The two post loops 24 of a handle 22 are inserted in the notches 66 of the holder with the press in open condition. The handle mounting portion 32 of each postloop is received in a slot 72. The escutcheon plates at this time will be located a slight distance below the bottom of the holder, and the tops of said mounting portions will be in contact with the roofs of the slots (see Fig. 9). The purpose of disposing the escutcheon plates slightly below the bottom surface of the holder 58 is to avoid placing pressure on the joints between the escutcheon plate and the posts; in the apparatus described, the pressure on closing of the press is absorbed by the tops of the posts. On insertion of the posts, the friction detents 77 are cammed outwardly against springs 81 to retain the posts in position.
Next, the bearing plates 50 are placed in the channel 107 of the levelling plate 88 with the plate openings 54 aligned with the openings 108 in the channel. Now the wall 48 of a piece of luggage is placed on the levelling plate with the portion of the wall to which the handle is to be secured located over the channel. The ram thereupon is lowered with enough force to drive the chamfered ends of the attaching shanks through the luggage wall, said ends, upon emerging, passing through the openings in the bearing plates 50.
When the posts first touch the upper surface of the luggage wall, said wall will be pressed against the levelling plate 88 to depress the same until the undersurface of the wall squeezes the escutcheon plate against the peripheral flange 116. This lowering of the plate 88 assures levelling of the luggage wall so that said wall surely presents a surface set squarely to the posts. This is of particular importance due to the comparatively narrow width of the levelling plate which is necessarily slender, since it must fit under narrow as well as wide luggage walls and since the anvil 60 is frequently canted to facilitate placement of the die parts in a kickpress.
If desired, additional means may be included to assure leveling of the luggage wall. Such means may constitute a spring mounted leveling pad 118 carried by the holder 58 and mounted thereon in such fashion as to present a lower surface parallel to the levelling plate 88 and yet be vertically slidable relative to the holder. A series of springs (not shown) urges the pad 118 downwardly toward an idle position in which its lower surface is slightly below the bottoms of posts mounted in the holder. Thus, the first surface to engage the top of the luggage wall will be that of the leveling pad 118. It will be understood that there are two leveling pads 118, one on each side of the holder, and a suitable mounting for each of said pads, said mounting being similar to that shown for the levelling plate 88.
It will be observed that by using a mounting for the levelling plate 88 which permits the luggage wall to be lowered to the bearing plate, I am able initially to provide clearance between the two, thus simplifying insertion of the bearing plates in their channel and preventing the presence of splinters in the die from interfering with proper mounting of the posts.
When the lower ends of the hollow posts eventually reach the die surfaces 110, the mouths of the blind bores will be turned outwardly and curled back up against the bearing plate to firmly press them against the undersurface of the luggage wall, thus securely fastening the two post loops to the luggage. Any core of wood which tends to leave the luggage wail before the same is fully pierced by the post will be held back by the bearing plate and by the protuberance 112 at the center of the die. Moreover, said protuberance will compress the core at and before the time that the tip of the post emerges from the lower surface of the luggage wall.
The apparatus and method described and shown but not claimed herein are shown, described and claimed in my copending divisional applications for Apparatus for Mounting Luggage Hardware and for Method for Mounting Luggage Hardware, Serial Nos. 765,912 and 765,913, respectively, filed on October 7, 1958.
It thus will be seen that there are provided devices which achieve the several objects of the invention and are well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein described, or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
