Description

F. L. DAVIS Dec. M, 1965 QUICK RELEASABLE BUCKLE WITH BELT LENGTH ADJUSTMENTS Filed March 18, 1964 INVENTOR. FRANK L. DAV/5 BY M ' Aria/PAM) United States Patent 3,222,739 QUICK RELEASABLE BUCKLE WITH BELT LENGTH ADJUSTMENTS Frank L. Davis, 30 Mariners Lane, Northport, Long Island, N.Y. Filed Mar. 18, 1964, Ser. No. 352,857 Claims. (CI. 2475) The invention herein disclosed relates to belt buckles and special objects of the invention are to provide a buckle which can be quickly connected and disconnected and which will have incorporated in it means for readily effecting belt length adjustments.
Other objects of the invention are to provide a buckle construction incorporating such features, which will be very simple and inexpensive in construction.
Other desirable objects and the novel features of construction, combinations and arrangement of parts by which such objects are accomplished are set forth and will appear in the course of the following specification.
The drawing accompanying and forming part of the specification is illustrative of present practical embodiments of the invention but structure may be modified and changed as regards the immediate illustration, all within the true intent and scope of the invention as hereinafter defined and claimed.
FIG. 1 in the drawing is a plan view of one of the buckles in the coupled relation, with portions of the belt or webbing broken away.
FIG. 2 is a broken, sectional view of the parts appearing on substantially the plane of line 2-2 in FIG. 1.
FIG. 3 is a plan view of the separated buckle parts.
FIG. 4 is a part sectional edge View illustrating separation and engagement of the buckle parts.
FIG. 5 is a broken plan view of a simpler, modified form of the invention.
FIG. 6 is a broken sectional view on substantially the plane of line 6-6 in FIG. 5.
FIG. 7 is a plan view of the separated buckle parts illustrated in FIGS. 5 and 6.
The form of the invention shown in FIGS. 1 to 4 consists of two sheet metal plates, 10 and 11, the first having a cross slot 12 for entry of the head 13 of the other part and each part having a snubbing ridge and three slots for conforming a belt end over such ridge.
The first member, constituting in effect the keeper part of the buckle, is shown as cross corrugated in the form of a rounded ridge 14 having the shape of an inverted V, over which one belt end portion 15 is looped at 16 after passage downward through an edge slot 17 and thence upward through slot 12 at the far side of the ridge, and over the ridge and inward through slot 18 in the near side of the ridge and beneath a snubbing corner 19 and upward through slot 17, where the ultimate end of that belt strap overlies the main portion 15. Thus as appears in FIG. 2, the end portion will be firmly held snubbed about the ridge 14 and by the snubbing shoulder 19 at the foot of the ridge, with the free end 20 con veniently positioned for adjustment of the belt length by pulling to tighten or to be slacked for increasing the belt length.
With this construction the cross slot 12 in the side of the ridge is utilized both for passage of the head on the other belt part and for passage of the belt itself, and in this location that part of the belt extending through slot 12 forms a stop limiting the movement of the head 13 in the unlocking or releasing direction.
The other, head forming member of the buckle has a similar belt adjustment construction in the form of an inverted-V ridge 21 over which a loop 22 of the belt section 23 is extended through cross slots 24 and 25 in the sides of the ridge, beneath a snubbing shoulder 26 and Patented Dec. 14, 1965 through slot 27 in the edge portion of that plate, leaving a free end portion 28 exposed for length adjustment.
Except for the raised ridge 21 the head portion of the buckle may be a flat plate as shown, with the head part 13 connected with the body of the plate by a reduced neck portion 29 designed to fit in and be laterally retained in the reduced side extension 30 of the receiving slot 12.
For easy entry and release purposes, the side extension 30 for receiving the neck 29 of the head part of the buckle is shown connected with the full length part of the slot 12 by shouldered enlargement 31 slightly longer than the head 13, through which the head may be directly passed in engaging and uncoupling the buckle parts.
The laterally extended neck receiving port 30 of the cross slot is shown as located in an inclined wall portion 32 of the plate 10, upon which the head will ride under tension on the belt, thus to become more securely locked in place.
A reversely angled shoulder 33 is shown left at the foot of the inclined wall 32 to serve as a stop limiting movement and preventing accidential release of the head through the widened portion 31 of the belt receiving slot 12.
The keeper part of the buckle, plate 10, is shown equipped with a handle portion 34, in the form of an extension of the inclined wall 32, overlying the head part, in the connected relation shown in FIGS. 1 and 2, and constituting as such a cover or guard which may be lifted as outlined in FIG. 4 to slide the head portion down the inclined wall 32 and through the release slot 31.
With the buckle parts relatively inclined as in FIG. 4, it is easy to effect the disconnection or engagement of the buckle parts, and at any time, when tension on the belt is released, the free ends 20 and 28 of the belt may he slipped one way or the other to shorten or to lengthen the belt.
The holding means illustrated enable infinite length adjustment and such adjustments may be effected at either one or the other of the two belt parts or at both parts, possibly to even the ends of the belt.
These adjustment devices hold the belt or webbing firmly in any adjusted relation and provide efficient securing means for the belt, easily assembled and avoiding any need for stitching or other such fastening heretofore employed.
While the buckle described is particularly simple and inexpensive, the construction may be further simplified and reduced in cost by eliminating the edge slots 17 and 27 in the two parts and the material necessary to provide these slots.
This simplified structure is shown in FIGS 5, 6 and 7 and involves departure from the first described construction only in that the keeper and head parts 10 and 11 are shortened in length to the extent indicated at 35, 36, FIG. 7, eliminating the edge slot portions 17 and 27 appearing in FIG. 3.
Accordingly the same reference characters are employed in FIGS. 5, 6 and 7 to designate corresponding parts.
The second form of the buckle particularly can be of very light weight and occupy small space adapting it for many uses where these characteristics are important.
Also in this second form of the invention adjustments of the belt length may be effected more readily, in some instances while the buckle is coupled together, for, with tension on the belt released, the free ends 20 and 28 may be readily slipped one way or the other and yet be securely gripped and held with the belt under tension.
The first form shown, FIGS. 1 to 4, has the advantage that adjustments made will usually be retained when the buckle is closed again because of the further grip on the 3 belt ends effected by extending these end portions through the additional edge slots 17 and 27, FIG. 2.
Because of the simple inexpensive construction, these buckles are adapted for many difl erent uses where webbing is used and there is a need for adjusting the ends to be connected and for enabling quick coupling and uncoupling of such ends.
In both constructions the loop of webbing 16 may operate as a cushion for the end of the head 13, FIGS. 2 and 5, and the loop 22 about the ridge 21 serve as a cushion stop for the handle 34, preventing looseness and rattling.
What is claimed is:
1. A quick releasable buckle with belt length adjustments comprising the combination of sheet metal plates,
one of said plates having a keeper slot and the other of said plates having a head to pass through said slot and be retained by a surface of the plate in which the slot is formed,
each of said plates having a cross ridge in the shape of an inverted V, with cross slots in the relatively inclined walls forming the ridges,
belt forming webbing extending through said cross slots and looped over said cross ridges,
said keeper slot in the one plate being a continuation of a cross slot in that plate whereby the loop of webbing about the cross ridge of the plate in which said slot is formed is disposed in opposition to the head of the other buckle plate to act as a stop limiting movement of said head in the releasing direction, and
the plate having the keeper slot having :a wall inclined with respect to the adjacent portion of said V-shaped cross ridge and supporting said head in the engaged relation of the plates, said inclined wall having an aperture which forms an end surface of said continuation of said cross slot, said inclined wall having a handle extension projecting as a cover over the webbing holding ridged portion of said head-carrying plate.
2. The invention according to claim 1 in which the webbing receiving ends of the plates are extended and cross slots are formed in said extended end portions through which the end portions of the webbing are passed.
3. The invention according to claim 1 with a reversely inclined shoulder at the foot of said inclined wall serving as a stop limiting movement of said head toward release position of said head through the keeper slot.
4. The invention according to claim 1 with said handle being engageable with the webbing looped over the ridged portion of the head-carrying plate of the buckle.
5. A quick releasable buckle combination comprising companion plates of sheet material engageable in overlying relation and having narrow transverse belt web-receiving cross slots in the outer end portions of the same,
