Abstract

A latch system is provided having utility in securing a door or planar member in a fixed position within a housing having a portal. The portal includes a defined periphery with a plurality of apertures therein. The planar member is pivotally mounted adjacent the portal. A rotatable member is mounted adjacent to the planar member. The latch system also includes a plurality of elongate members, each of the elongate members having a first end adapted to slidably enter an associated aperture and a second end pivotally mounted to the rotatable member, wherein rotation of the rotatable member will cause both angular and axial movement of the elongate members. Rotation of the rotatable member in one direction causes the first ends of the elongate member to engage associated apertures securing the planar member in a closed position. Rotation in the opposite direction causes the first ends to disengage from associated apertures permitting the planar member to pivot, allowing the planar member to be moved into an open position. Guide members are provided for assisting and guiding movement of the plurality of elongate members into and out of the apertures. In accordance with an important feature of the present invention, a latch element is provided intermediate the rotatable member and at least one associated guide member, wherein the latch element may be utilized to selectively restrict angular movement of at least one member of the plurality of elongate members.

Claims

1. A latch system having utility in securing a planar member in a fixed position comprising:

a housing having a portal, said portal having a defined periphery with a plurality of apertures within said defined periphery, said planar member being pivotally mounted adjacent said portal;

a rotatable member mounted adjacent to said planar member, wherein said rotatable member rotates in a plane parallel to said planar member;

a plurality of elongate members, each of said plurality of elongate members having a first end and a second end, each first end being adapted to slidably enter an associated aperture and each second end being pivotally mounted to said rotatable member, wherein rotation of said rotatable member will cause angular and axial movement of each of said plurality of elongate members and wherein rotation of said rotatable member in a first direction will cause each first end to engage an associated aperture and rotation in a second direction will cause each first end to disengage from said associated aperture;

a plurality of guide members for assisting in guiding movement of said plurality of elongate members into and out of said plurality of apertures, each of said plurality of guide members located adjacent to said planar member intermediate an associated aperture and said rotatable member and having a guiding aperture sized to slidably receive an associated elongate member; and

latch means attached to said planar member and located intermediate said rotatable member and at least one associated guide member, said latch means comprising a flange having a beveled edge adapted to cooperate with an elongate member of said plurality of elongate members and a groove adjacent said beveled edge adapted to engage said elongate member, wherein rotation of said rotatable member in said first direction causes said elongate member to cooperate with said beveled edge to cause said groove to receive and secure said elongate member, whereby further angular movement of said elongate member is restricted.

2. The latch system of claim 1 wherein said housing is a kennel for housing at least one animal.

3. The latch system of claim 1 wherein said planar member comprises a grid.

4. The latch system of claim 1 wherein said planar member comprises a polymeric material.

5. The latch system of claim 1 wherein said planar member comprises a metallic material.

6. The latch system of claim 1 wherein said rotatable member is of a size suitable for rotation by a human hand.

7. The latch system of claim 1 wherein a handle suitable for manipulation by human digits is attached to said rotatable member.

8. The latch system of claim 1 wherein said latch means is a grasping member, wherein said grasping member engages an elongate member when a first end of said elongate member has engaged an aperture associated with said elongate member resulting in restriction of angular movement of said elongate member.

9. The locking system of claim 1 wherein said latch means further comprises:

a base;

said flange positioned over said base having an upper side and a bottom side, said bottom side facing said base, said beveled edge adapted to cooperate with said elongate member, and said groove adapted to engage said elongate member, said flange being positioned such that said beveled edge, normally being biased in a position towards said base, cooperates with said elongate member to bias said groove away from said base and allows said elongate member to move towards said groove until said groove receives said elongate member, whereby said groove becomes biased in a position towards said base and further angular movement of said associated elongate member is restricted until said groove is forcibly biased into a position away from said associated elongate member; and

an attaching member connecting said flange to said base.

10. The latch system of claim 1 wherein said plurality of elongate members comprises four rods.
