Description

Jan. 30, 1962 c. A. BREITMAYER APPARATUS FOR LATCHING AND OPENING CONTAINER COVERS Filed Oct. 22, 1959 INVENTOR. CARL A. BREITMAYER United States Patent 3,018,917 APPARATUS FOR LATQHING AND OPENING CONTAINER COVERS Carl A. Breitmayer, 212 N. Grand, Monrovia, Calif. Filed Oct. 22, 1959, Ser. No. 847,995 2 Claims. (Cl. 22036) The invention relates to apparatus for opening and latching covers of containers and more particularly to such covers that are hinged in pairs to open oppositely.

Many different types of containers are carried about from place to place by their users. Closed or covered containers such as womens handbags and purses, tool boxes and containers for small parts for assemblies, are normally carried closed. When access to the container is desired, the container is usually placed on some stable surface and the container is opened and the desired object is removed from it. Often times objects other than the container being carried interfere with removing another object from within the container. Many closing arrangements of containers such as purses and tool boxes, etc., require both hands to open the container. This of course is a handicap when the bearer of the container is carrying more than the container. I have invented a container which may be opened with one hand to give complete access to its interior. The apparatus of the invention preferably includes latching means to hold the cover or covers of the container closed in an effective manner.

The invention contemplates apparatus such as a con tainer having a hinged cover over the container openings. A carryinghandle is pivotably mounted near the hinge line of the. cover. Preferably the carrying handle for the container extends outwardly away from the pivot axis of the handle. The handle is so mounted that it may pivot over the outer surface of the hinged cover. A link which may be flexible extend between the handle and a point remote from the hinge line of the cover. The length of the link is such that when the link is fixed to a point on the handle remote from its pivot axis rotation of the carrying handle away from the cover draws the cover away from the container opener, giving access to the container interior.

The preferred embodiment of the invention combines the above recited apparatus with a latch cam on the container which is engaged when the carrying handle is pivoted over the cover. The engagement between the handle, and the cover by means of the latch cam is such that the cover cannot be lifted away from the container opening. The linking means between the carrying handle and the cover is such that the means exerts no force to open the cover when the handle is positioned to latch the cover.

The invention is equally applicable to containers having two hinged covers and it is particularly adapted to use with containers having hinged covers whose hinge lines are parallel and whose covers open oppositely. In apparatus of this nature latching cams are provided to be associated with each cover and linking means are provided between the carrying handle and each cover.

The apparatus of the invention makes possible by economical mechanical apparatus a family of containers whose covers are easily opened by simply twisting the handle with one hand, giving easy access to the interior. The preferred embodiment of the invention provides means for latching the covers in tightly closed position when the handle is turned so that the covers close the container openings. These and other advantages of the invention are apparent in the following detailed description and drawing in which:

FIG. 1 is a plan view of a preferred embodiment of the invention in which the carrying handle is oriented to Patented Jan. 30, 1962 draw each of the covers of the container into open positions;

FIG. 2 is an elevational view of the apparatus of FIG. 2;

FIG. 3 is an alternate embodiment of the invention utilized with a partitioned container; and

FIG. 4 is a sectional elevation partly broken away and taken along line 44 of FIG. 3.

A container 11 in FIGS. 1 and 2 has a bottom wall 12, a curving continuous side wall 13 and a top mounting piece 14 located centrally of the top area of the container. Access to the interior 15 of the container is had through

openings

17 and 18 on opposite sides of mounting piece 14.

A pair of

covers

21, 22 are hinged to opposite sides of the mounting piece by pairs of

binge pins

24, 25 respectively. A carrying handle 27 is pivotably mounted at the center of the mounting piece. The handle pivots about a pivot point indicated at 28. The carrying handle extends in ends 51, 32 sufficiently displaced from the pivot axis that the handle when turned overlies the closed covers in the position shown by dotted lines 33 FIG. 1. The handle may be pivoted to the mounting piece in the manner shown and described later with respect to the device of FIGS. 3 and 4.

Each of the covers 21, 22 has a

latch cam

34, 35 respectively. A first flexible link 41 extends from end 31 of the carrying handle and is fixed at a point 42 on cover 21 remote from its hinge line. The opposite end of flexible link 41 is fixed by conventional means to the extreme outer portion of carrying handle 27. A second flexible link 43 connects between end 32 of handle 27 and cover 22. The second link is oriented with respect to the handle and cover similarly but oppositely to first link 41.

It can be appreciated from the drawing and description that with handle 27 turned to the orientation shown in FIGS. 1 and 2 links 41 and 43 are pulled taut and draw the

covers

21 and 22 away from

openings

17 and 18 to give access to interior 15 of the container. Conversely, when the handle is pivoted to the position indicated by dotted lines 33, the flexible links slacken and the covers return to closed position. v

The preferred embodiment as heretofore described ha means for latching the covers into closed position. The embodiment of FIGS. 1 and 2 is provided with

latch cams

34, 35 against which the pivoted carrying handle bears. Further pivoting of handle 28 in the direction of arrow 51 causes the bottom surface 52 on either end of the carrying handle to engage ramps 37 of the latch cams and thereby latch the covers into closed position. The friction bind between the handle and the latch cams is such that the handle does not turn by itself to unlatch the covers.

FIGS. 3 and 4 illustrate an embodiment of the invention in which the interior of a container 61 is divided into a plurality of compartments beneath the hinged covers. Such a container might be used as a parts tray for various types of craftsmen. As in the previously described embodiment, container 61 of FIGS. 3 and 4 has a bottom wall 62, pairs of

parallel side walls

63, 64 and 65, 66 which support oppositely opening hinged covers 69, 70 and a central mounting piece 71. The interior of the container is divided into a plurality of compartments such as the compartments 72, 72A, 72B. A central divider 74 separates the compartment into two rows and also helps support mounting piece 71.

The mounting piece has a pivot bearing 75 centrally located at the midpoint of the container. A conventional wood screw 76 extends upwardly through the bearing to be fixed in a carrying handle 78. The bearing is free to turn with respect to the mounting piece so that the handle may pivot freely about the vertical axis of the screw. Many other pivoting arrangements may be used within the scope of the invention, but the presently described combination has proved to be smooth working and economical. A similar arrangement can be utilized in the embodiment of FIGS. 1 and 2, as previously suggested.

As in the first embodiment, latch cams 81, 82, are fixed one to each of the covers or

lids

69, 70. Each latch cam has a sloping cam ramp 84 and a vertical stop shoulder 85. The cams latch the covers in their closed position when the handle is pivoted to the position of FIG. 3.

First and

second links

88, 89 join handle ends 91, 92 to

covers

69, 70 respectively. The links are preferably of fine link chain, but may be of nylon cord or fine braided wire. The links serve to draw the covers open when the carrying handle is pivoted about the axis formed by bearing 75 and screw 76. Each link is long enough that the handle clears the ramp of the two latch cams before the link becomes taut and lifts the covers into open position.

The embodiment of FIGS. 3 and 4 operates in the same manner as the embodiment of FIGS. 1 and 2. The carrying handle is pivoted in one direction to slacken the links and latch the cover or covers in closed position, and is pivoted in the other direction to release the latching action and draw the links taut to open the covers.

The illustrative embodiments have shown containers having two covers. The invention benefits containers having only one cover or a plurality of covers in the same fashion. The invention makes possible containers simpler to open than conventional covered containers. The most of manufacture is no greater than with conventionally secured covers, and the ease of access is increased many fold. While handbags and purses are the principal beneficiaries of the inventive structure, all types of containers are possible embodying the inventive principle.
