Separable keyholder with multiple keyrings

A key holder comprising two similarly shaped parts each having secured thereto a retainer for a plurality of apertured keys, the holder having at least one pair of mating latching structures holding the parts together when engaged and permitting the parts to be separated by only manually pulling the parts apart, each latching structure including a combination of a protuberance on one part and a cooperating protuberance-retaining recess on the other part, each part having at least three distinct layers with first and second of the layers being thin flat and parallel and defining a space therebetween and a third layer in a stratum parallel to and between said first and second layers and offset in said stratum with respect to the first and second layers, the third layer of each part lying parallel to and between the first and second layers of the other part and having opposite faces exposed, respectively, to opposed faces of those first and second layers of the other part when the parts are engaged, each third layer having one said protuberance on at least one of its exposed faces, which protuberances are received in and retained by respective protuberance-retaining recesses in opposing faces of the layers of the other part when said parts are engaged, said key holder further comprising a hole through each of said parts, said holes being concentric with a common axis extending perpendicularly to said parallel structures when the parts are engaged whereby a removable locking plug can be placed manually in said holes to prevent said pulling separation of said parts until said plug is manually removed from said hole.

A key holder comprising two parts latched together by releasable latching means defined by portions of said parts, said parts being movable to and from their relatively latched positions of engagement by manually pushing and pulling the parts toward or away from each other along a particular direction, each of said parts having secured thereto a key retainer for holding a plurality of apertured keys, said key retainers being secured to said parts at respective points spaced from each other essentially along a line parallel to said direction, each of said parts comprising two layers in two parallel spaced strata and having a space between said layers, each of said parts also having a third layer in a stratum parallel to and between said two parallel strata, said third layer of each part being slidable in said direction between and in engagement with said two layers of the other part and into said space when said parts are manually pushed together into latched engagement, said latching means comprising at least two distinct relatively spaced pairs of cooperating interfering latching portions, one of the latching portions of each pair being on one of said two layers of one of said parts and the other latching portion of that pair being on the third layer of the other of said parts, said latching means including resilient means for biasing the latching portions of each pair of cooperating interfering latching portions to their relative latching positions to hold said interfering latching portions against separation except when the parts are pulled apart by an intentional manual separating pull exerted on said key retainers along said direction, said interfering latching portions of each such pair interacting during the pushing of the parts into latched engagement, and during such an intentional manual separating pull, to displace at least one of said interfering portions of such pair against the bias of said resilient means to permit the parts to be respectively moved into latched engagement or to release the latching means in response to such a manual separating pull on said key retainers whereby the key holder parts can be completely separated by such a pull.

A key holder comprising two identically shaped parts latched together by releasable latching means defined by portions of said identically shaped parts, said parts being movable to and from their relatively latched positions of engagement by manually pushing and pulling the parts toward or away from each other along a particular direction, each of said parts having secured thereto a key retainer for holding a plurality of apertured keys, each of said parts comprising two layers in two parallel spaced strata and having opposed parallel faces defining a space between said layers, each of said parts also having a third layer in a stratum parallel to and between said two parallel strata, said third layer of each part having outer flat surfaces slidable on said opposed parallel faces of the other part in said direction between said two layers of the other part into said space when said parts are manually pushed together into latched engagement, said latching means comprising at least two distinct relatively spaced pairs of cooperating interfering latching portions, one of the latching portions of each pair being on one of said surfaces of said third layer of one part and the other latching portion of that pair being located on a respective one of said parallel faces of a layer of the other of said parts, said parts including resilient means for biasing the latching portions of each pair of cooperating interfering latching portions to their relative latching positions to hold said interfering latching portions against separation except when the parts are pulled apart by an intentional manual separating pull exerted on said key retainers along said direction, said interfering latching portions of each such pair interacting during the pushing of the parts into latched engagement, and during such an intentional manual separating pull, to displace at least one of said interfering portions of such pair against the bias of said resilient means to permit the parts to be respectively moved into latched engagement or completely separated.
