Patent number: 7401700Abstract: The present invention is directed to a tool accessory case having a first and a second housing member pivotally connected to each other along a hinge portion and forming a tool holding cavity. The tool accessory case also has at least one index configured for receiving at least one elongated tool accessory disposed in one of the housing members. The index has an upper guide for contacting an upper portion of the tool accessory, and a lower guide for contacting a lower portion of the tool accessory. Further, a flexible arm is included on either the index or one of the first and second housing members. The flexible arm is configured for deforming and applying a lateral pressure to the lower portion of the tool accessory for the purpose of positively retaining the tool accessory in the index. The tool accessory is slidingly received by the index, and the lateral pressure is applied by the flexible arm when the tool accessory is generally entirely received by the index.Type: GrantFiled: February 22, 2005Date of Patent: July 22, 2008Assignee: Robert Bosch GmbHInventors: Hagen W.

Patent number: 7401698Abstract: A preferred embodiment of the present invention is directed to a tool accessory case having first and second housing members pivotally connected to each other along a hinge portion and forming a tool holding cavity. A latch is connected to the first housing member and is moveable between latched and unlatched positions. The latch has a gripping structure configured for gripping the second housing member, and at least one flexure member configured to contact the first housing member and bias the latch toward the latched position. The latch also has at least one fixed hinge guide for pivoting with respect to the first housing member and with respect to the flexure member. The tool accessory case also has a receiving structure disposed on the second housing member and is configured to receive the gripping structure of the latch when the latch is in the latched position.Type: GrantFiled: February 22, 2005Date of Patent: July 22, 2008Assignee: Robert Bosch GmbHInventors: Hagen W.
