Description
SPECIFICATION
Improvements in and relating to buckles
The field of the invention relates to buckles for use in conjunction with belts, straps, suspenders, braces, and similarly shaped members.
Buckles are commonly used for fastening seat belts, straps, harnesses, and other equipment. A strap may be pulled through the buckle to a desired tightness around a person or piece of equipment. Gripping means provided within the buckle will prevent the strap from loosening.
Bucles comprising two separable members are desirable where it is necessary to open a strap to release the person or equipment. U.S. Patents
Nos. 3,196,878, 3,25-1,1 10, 3,798,71 1 and 3,844,000 disclose buckles or fasteners having detachable members. When one wishes to free himself from a strap or harness, a release mechanism is actuated to separate the two members of the buckle.
The invention is directed to an improved buckle including two separable members. Such buckles have a wide variety of applications and have gained commercial acceptance. A principal object of the invention is to provide a structurally and functionally acceptable buckle of equal, if not better performance than presently known devices.
The buckle includes two mating parts. A male member is provided which is capable of insertion within a suitably formed female member. Means are provided for releasably coupling the two members.
The male member includes a substantially plate-like portion having a projection emanating upwardly at an angle from one side thereof. A pair of stops are provided on each side of the plate-like portion. The stops are positioned near one end thereof and function in a manner explained below.
A slotted, relatively thick member is provided at the end of the plate-like portion including the stops. It may be formed integrally with the platelike portion, and defines a shoulder on each side of said portion. The width of the thick member is also greater than the width of the plate-like portion.
The female member includes an opposing pair of parallel structures defining a slot there between.
The slot is of suitable dimensions for accommodating the plate-like portion of the male member The parallel structures are substantially identical, and each has the cross section of a widened U. They may be joined together at a seam or integrally moulded. Each structure has a pair of openings substantially perpendicular to the slot between them. The openings are defined by the peripheral walls of the structure and crossing pieces between the longitudinal edges.
A serrated column is positioned within the slot adjacent to one of the openings in the female member. The other opening, which is nearest the point at which the male member enters the slot, includes a rearwardly extending lip. The lip is designed for preventing the angular projection from being forced over one of the parallel structures of the female member when the buckle is subjected to high tensile forces.
The entrance portion of the slot within the female member is provided with shoulders or notches which are appropriately shaped for receiving the stops of the male member. By having similar dimensions to the stops, there is less play between the members.
One form of buckle constructed in accordance with the invention will now be described by way of example only with reference to the accompanying drawings, in which:
Figure 1 is an exploded perspective view of a buckle according to the invention;
Figure 2 is a plan view of an assembled buckle having a strap attached thereto;
Figure 3 is a sectional elevation view of the assembled buckle in use;
Figure 4 is a sectional elevation view of the buckle showing the step of separating the male and female members of said buckle; and
Figure 5 is an end view of the female member of the buckle.
The invention is directed to a buckle 10 including two detachable members. A male member 12 is provided for insertion with a female member 14. The male member 12 includes a substantially plate-like portion 1 6 having a projection 1 8 emanating therefrom. The projection 1 8 forms an acute angle with the plate-like portion 16, and may be integrally formed therewith. The base portion of the projection includes a grooved area 20 which reduces its thickness at this point. A similar groove 21 may be formed at the opposite side. By manufacturing the buckle from a suitable polymeric material having sufficient resiliency, the projection will be movable about its base at the area of reduced thickness.
The angle it makes with the plate-like portion 1 6 will accordingly change depending upon the presence or absence of a force applied thereto.
Acceptable materials for manufacture are described in the prior art patents noted above.
A series of parallel ridges 22 is provided on the projection 1 8. A slightly higher ridge 24 surrounds these ridges 22. This ridge 24 is interrupted by and partially defines a groove 26 near the top of the projection 1 8.
To facilitate the movement of the projection 1 8, it extends over a cut out area 28 of the plate-like portion 1 6. The projection flares outwardly towards its top as does the cut out area.
A pair of stops 30 protrude from the planar surface of the plate-like portion 1 6. In the embodiment shown in the drawings, the stops have a square cross-sectional configuration. A second pair of stops (not shown) is positioned opposite the first pair.
A relative thick slotted member 32 is provided at the end of the plate-like portion 1 6 adjacent the stops 30. The slot 34 is suitable for receiving a strap or belt as shown in Figure 2. The slotted member 32 may be formed integrally with the remainder of the male member 12, and defines a shoulder 38 on both sides of the plate-like portion
1 6. The width of the slotted member is also greater than the width of said portion 1 6, and extends laterally therefrom at both sides.
The female member 14 includes an opposing pair of parallel structures 40, 42 defining a rectangular slot 44 therebetween. Each parallel structure has a cross section of a wide U. When joined, they define a flattened housing having upper, lower, and side walls with the slot 44 extending longitudinally therethrough. One end 48 of the housing is closed. The other is open and defines an entrance 50 to the slot 44. Figure 5 shows the configuration of the entrance 50.
The entrance 50 and slot 44 are designed for accommodating the plate-like portion 1 6 of the male member. The slot has large enough dimensions to permit easy insertion, but is not so large that there is excess play. Two pairs of notches 52 are provided near the entrance 50 for accommodating the stops 30. The notches are each defined by three side walls and a shoulder 54, and extend perpendicular to said slot. They have approximately the same shape as the stops, and serve to minimize lateral play of the male member. The stops and notches are positioned such that a gap 56 is created upon full insertion of the male member.
Each parallel structure 40, 42 is formed with a pair of openings 58, 60 separated by a crossing piece 62. The remainder of the upper face of each parallel structure includes front and rear lateral members 64, 66 and longitudinal members 68, 70. The parallel structures are integrally formed, and upon assembly, the openings are registrable.
A lip 72 extends rearwardly from the front lateral member 64 over a portion of the adjacent opening 58. The lip 72 is rectangular in shape so that it can fit within groove 26 upon insertion of the male member 12 within the slot 44. The projection 1 8 snaps towards the lip at groove 26 when the buckle is fully assembled. In this manner, it will not tend to slip over the front lateral member 64 when the buckle is subjected to high tensile forces. A portion of member 64 extends below the lip 72 to serve as an abutment.
A free-moving column 74 having ridges 75 on opposite sides thereof is positioned within the slot 44 and in line with the rearward opening 60. The crossing piece 62 may be formed with a ridge (not shown) on its interior surface to prevent the column from moving beyond the opening 60. A strap or belt 76 may be looped around the column as shown in Figure 3. The ridges 75 serve to prevent undesired loosening of the belt.
In operation, a pair of belts 36, 37 are secured to the male and female members 12, 14 respectively. Belt 36 is looped within slot 34 and belt 76 about column 74. The plate-like portion 1 6 of the male member is inserted within the slot 44, initially depressing the projection as ridges 24 contact the inner surface of lateral member 64.
Once fully inserted, the projection snaps away from said plate-like member and towards the lip 72. The stops 30 fit within notches 52 and prevent excessive lateral movement of the male member.
To separate the buckle, one applies pressure to the projection 1 8 as shown in Figure 4. The projection is accessible through the opening 58 when the buckle is assembled. The pressure enables one to slide the male member from the slot as it will avoid contact with member 64.
Ridges 22 facilitate the separation of the members.
It will be appreciated that the invention provides a buckle which is suitable for a variety of applications, including but not limited to safety belts, belts in scuba and other diving equipment, and other uses.
