Abstract

A cabinet (1) comprising: a housing (10); two or more storage units (30, 50), each accommodated within the housing (10) and displaceable between a closed position in which a majority of the storage unit (30, 50) is disposed within the housing (10) and an open position in which the storage unit (30, 50) projects from the housing (10) to an extent greater than in said closed position; and a blocking mechanism (70) comprising two or more blocking members (71b, 71c), each associated with its corresponding storage unit (30, 50) and configured for selectively arresting said corresponding storage unit (30, 50) in its closed position; the blocking mechanism (70) being displaceable between an unblocked state in which each one of the storage units (30, 50) is free to be displaced from its closed position to its open position and a blocked state in which at least one and no more than all but one of the storage units (30, 50) are arrested in their closed position by their corresponding blocking members (71b, 71c). The association between the blocking mechanism (70) and the storage units (30, 50) is such that, when said blocking mechanism (70) is in its unblocked position, displacement of one of said storage units (30, 50) from its closed position to its open position induces displacement of the blocking mechanism (70) from its unblocked state to its blocked state.

First claim

The invention claimed is:

1. A cabinet, comprising:
a housing;
two or more storage units, the storage units accommodated within the housing and displaceable between a closed position in which the storage units are disposed within the housing and an open position in which at least one of the storage units projects from the housing to an extent greater than in the closed position, each of the storage units comprising a guiding portion and a restricting arrangement; and
a blocking mechanism, the blocking mechanism comprising an integrally molded member integrally formed with two or more blocking-following members and a longitudinal body, each of the blocking-following members comprises one of two or more blocking members and one of two or more following members, each of said blocking-following members is formed on an L-shaped arm of the blocking mechanism, each said L-shaped arm comprising a long section generally parallel to a vertical axis of the housing and a short section generally normal to the long section, each long section extending from the longitudinal body, each blocking-following member disposed on one of the short sections;
wherein the blocking mechanism is displaceable between an unblocked state in which each of the storage units is free to be displaced from the closed position to the open position and a blocked state in which all but one of the storage units are arrested in the closed position, each of the storage units is arrested in the closed position by a corresponding one of the blocking members obstructing the restricting arrangement of said storage unit while the blocking mechanism is in the blocked state;
wherein when the blocking mechanism is in the unblocked state, displacement of one of the storage units from the closed position to the open position induces displacement of the blocking mechanism from the unblocked state to the blocked state;
wherein when the blocking mechanism is in the blocked state, displacement of one of the storage units from the open position to the closed position induces displacement of the blocking mechanism from the blocked state to the unblocked state; and
wherein each following member of the blocking-following members engages the guiding portion of one of the storage units during all steps of displacement of the one of the storage units from the closed position to the open position and during displacement of the one of the storage units from the open position to the closed position.

2. The cabinet according to claim 1 , wherein the restricting arrangement is constituted by restricting portions on the storage units, so that in the blocked state, corresponding ones of the blocking members are aligned with the restricting portions of corresponding ones of the storage units so that during an attempt to displace one of the corresponding ones of the storage units from the closed position to the open position, the corresponding ones of the blocking members are configured to engage the restricting portions of the restricting arrangement of the corresponding ones of the storage units to thereby obstruct and prevent displacement thereof.

3. The cabinet according to claim 1 , wherein the following members form a following arrangement, the following arrangement being associated with the storage units such that displacement of one of the storage units from the closed position to the open position entails displacement of the following arrangement from an inoperative state to an operative state, and the following arrangement being associated with the blocking mechanism such that displacement of the following arrangement from the inoperative state to the operative state entails displacement of the blocking mechanism from the unblocked state to the blocked state.

4. The cabinet according to claim 3 , wherein the guiding portion associated with the following member of each of the storage units is configured, so that during the displacement of the storage unit between the closed position and the open position, the following member slidingly engages the guiding portion, thereby changing the following arrangement between the inoperative state and the operative state, respectively.

5. The cabinet according to claim 1 , wherein the storage units are arranged within the cabinet along the vertical axis of the housing, and the longitudinal body of the blocking mechanism extends along the vertical axis, and wherein the blocking mechanism is configured to be displaced between the blocked state and the unblocked state along the vertical axis.

6. The cabinet according to claim 1 , wherein the blocking mechanism is normally urged into the unblocked state by gravity.
