Description

  The present invention relates to a kitchen knife, and more particularly, to a kitchen knife that holds the tip of a knife blade in a state in which it is pointed downward.

  2. Description of the Related Art Conventionally, for example, a kitchen knife holder that holds a knife blade tip in a downward direction is attached to an inner surface of a front plate of a drawer storage portion provided below a sink of a kitchen.

  In this case, unless a lock mechanism is provided in the drawer storage section to which the kitchen knife is attached or the lock mechanism is not provided in the kitchen knife itself, the risk of a small child accessing the knife knife and pulling out the knife from the knife knife is avoided. Can not do it. However, if the drawer storage unit is provided with a lock mechanism, the lock mechanism must be released each time the drawer storage unit is used, and the usability of the drawer storage unit is deteriorated.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a knife knife that can reliably prevent the risk of a small child pulling out a knife in accordance with a relatively simple configuration. .

In order to solve the above-described problem, in the present invention, in the knife insertion that holds the tip of the knife blade in a state of being directed downward,
A lock position that partially covers the insertion slot of the knife and prevents the knife from coming out of the insertion slot, and an unlocking position that allows the knife to retreat from the insertion slot and escape from the insertion slot A locking member movable between and
A line segment connecting the lock position and the unlock position extends obliquely with respect to the longitudinal direction of the insertion port ,
The lock member includes a plate member that moves in proximity to a lower surface of the upper member in which the insertion port is formed, and a grip portion that is connected to the plate member.
The upper member is formed with a guide opening that guides the movement of the lock member in a state in which the base portion of the grip portion penetrates,
The guide opening includes a first opening portion for guiding the lock member from the unlock position to a first intermediate position substantially parallel to the longitudinal direction of the insertion port, and the lock member from the first intermediate position. A second opening portion for leading the second intermediate position to a direction intersecting the longitudinal direction of the insertion port; and the locking member from the second intermediate position to the locking position substantially parallel to the longitudinal direction of the insertion port. And a knife opening characterized by having a third opening portion for guiding the knife.

  The knife insert according to the present invention has a lock position that partially covers the insertion slot of the knife and prevents the knife from coming out of the insertion slot, and allows the knife to retreat from the insertion slot and come out of the insertion slot. And a lock member movable between the lock release position. Here, a line segment connecting the lock position and the lock release position extends obliquely with respect to the longitudinal direction of the insertion slot.

  If the moving direction of the lock member is set parallel to the longitudinal direction of the insertion slot, it is necessary to ensure a certain distance between the two adjacent insertion slots, and the knife insertion becomes larger in the lateral direction. Moreover, when the moving direction of the lock member is set to be perpendicular to the longitudinal direction of the insertion slot (parallel to the short direction), the knife insertion is not only enlarged in the depth direction but also elongated along the longitudinal direction of the insertion slot. Since the extending lock member is moved in the short direction, the force required to move the lock member tends to increase.

  In the kitchen knife of the present invention, the overall movement direction of the lock member is set obliquely with respect to the longitudinal direction of the insertion slot, so that the knife knife does not increase in size in the horizontal direction or the depth direction. The lock member extending elongated along the longitudinal direction of the slot can be moved with a relatively small force. As a result, the knife insertion according to the present invention can reliably prevent the risk that a small child pulls out the knife in accordance with a relatively simple configuration.

  In the present invention, the lock member preferably has a plate member that moves close to the lower surface of the upper member in which the insertion port is formed. With this configuration, the main part of the lock mechanism is housed inside the kitchen knife, so that the beauty of the kitchen knife can be maintained and the outer surface of the kitchen knife can be easily cleaned.

  Further, in the present invention, the lock member has a grip portion connected to the plate member, and a guide opening for guiding the movement of the lock member is formed in the upper member of the kitchen knife with the base portion of the grip portion penetrating therethrough. It is preferable that In this case, the lock member can be stably and easily moved according to a relatively simple configuration.

  According to the present invention, the guide opening for guiding the movement of the lock member includes a first opening portion for guiding the lock member from the unlock position to the first intermediate position substantially parallel to the longitudinal direction of the insertion port, A second opening portion for guiding the member from the first intermediate position to the second intermediate position in a direction crossing the longitudinal direction of the insertion port; and a longitudinal direction of the insertion port from the second intermediate position to the locking position. It is preferable to have a third opening portion for guiding it substantially in parallel. In this case, for example, even if an impact associated with opening and closing (drawing and pushing back) of the drawer storage portion is transmitted to the knife, a safe structure is realized in which the lock member does not move from the locked position to the unlocked position due to the impact. be able to.
