Description

[Detailed Description of the Invention] The present invention relates to a drawer with a latch that has a latch function on the thin pull.More specifically, in order to provide the latch function with the thin pull, the latch can be opened with a push motion. It is attached to the entire upper width direction of the drawer body and the front plate of the drawer body, and the upper plate, lower plate, and back plate form a roughly U-shaped cross section with the front open. A handle is provided with grooves facing each other along its entire length between the handle and the handle, and a rotating shaft is pivotally supported on a pair of rotating bearings provided in the center of the handle, and the rotating shaft is provided with a rotating shaft in an upright position. The bulge formed at the lower end of the lever part is fixed integrally, and a leaf spring is installed between the back of the lever part, which is eccentric to the front with respect to the rotation axis, and the concave groove of the back plate to elastically bias the cabinet forward. A pull with a latch was completed by combining a latch cam that engages with a pin attached to a side plate and a latch portion that is fixed to a rotating shaft at the end of the drawer.

That is, in the drawer having a latch pull according to the present invention, a pull shown as 2 is provided on the front surface of a drawer main body shown as 1 in the figure, and the drawer main body 1 and 3 are
A latch portion 4 is provided between the cabinets shown as . Here, the drawer main body 1 is approximately box-shaped, consisting of a front plate 5, a bottom plate 6, a side plate 7, and a back plate, similar to various drawer main bodies 1 provided in a general cabinet 3. The handle 2 provided on the front plate 5 is a thin handle with at least the front side open as shown in the figure. The handle 2 shown in the figure is provided over the entire width of the upper end of the front plate 5, and a latch portion 4, which will be described later, is provided on a part of this part, and at the same time, a latch part 4 is provided on the front surface of the handle 2 in other parts. A handle 2 is used in which a business card or other card 9 can be inserted using an open portion 8. As shown in the figure, the front side is open 8, and a main body with a substantially U-shaped cross section is provided, with an upper plate 10, a lower plate 11, and a back plate 12 arranged at the top, bottom, and back, respectively. Card insertion grooves 13 facing each other are provided along the entire length between the middle and the middle. What is shown as 14 in the figure is an end cap formed at both ends of this handle 2.
Reference numeral 16 denotes a rotation bearing for pivotally supporting a rotation shaft 15 of the latch portion 4, which will be described later, and a card 9 can be inserted between this rotation bearing 16 and the end cap 14.

Next, as shown in the figure, the latch part 4 allows the lower end of the lever part 17 in the upright state of the rotary shaft 15, which is pivotally supported by the two rotary bearings 16, 16, to be rotatable together with the rotary shaft. At the same time, a latch cam 18 is similarly fixed to one end of the rotating shaft 15, that is, the left end as shown in FIG. 1, in a state substantially perpendicular to the lever portion 17. That is, the lever portion 17
By the rotation operation, the latch cam 18 can be rotated up and down as shown in FIG. Lever part 1
In order to fix the cam 7 and the latch cam 18 to the rotating shaft 15, in the illustrated example, the portion of the rotating shaft 15 is made into a square shape and fitted in a non-rotatable state, so that they rotate integrally with each other. There is. Further, the lower part of the lever part 17, that is, the part where it is attached to the rotating shaft 15, forms a slightly forward bulging part 19, and the lever part 17 is raised upward from this bulging part 19, so that the lever part 17 is connected to the rotating shaft. 15, and lever part 17
The tip is bent to form a finger contact part 20.
In the figure, reference numeral 21 indicates a pin attached to the side plate of the cabinet 3, which is locked based on the upward rotation of the latch cam 18, and reference numeral 22 indicates a pin attached to the back plate 12 for the card insertion.
This is a plate spring as an example of an elastic biasing means for the lever, which is attached between the lever and the back surface of the lever by using a groove provided in the lever.

By inserting a finger into the open part 8 on the front surface of the handle 2 and pressing the lever part 17 attached to the rotating shaft 15, the lever part 17 is tilted backward in the figure, that is, to the right in FIG. However, the latch cam 18 rotates from the solid line state to the imaginary line state and is disengaged from the pin 21. When the finger is released, the lever part 17 returns to the front side, that is, in the opening direction, due to the spring pressure of the leaf spring 22 provided on the back side of the lever part 17, and the latch cam 18 moves back toward the opening direction. In response to this, the state returns to the solid line state.

That is, the latch cam 18 can be freely engaged with or released from the pin 21 attached to the side plate of the cabinet 3 by simply inserting a finger into the release part 8 on the front surface of the handle 2. As shown in FIG. 2, the attachment of the parts does not require much depth within the handle 2, and a latch function can be provided even to a thin handle.

In addition, by inserting the card 9 between the opposed grooves 13 and 13 in the handles on both sides of the lever part 17, it is possible to shield the release state of the handles in this part, and at the same time, the card 9 has various built-in You can organize and write the table of contents and names of things.

As described above, the drawer with the latch pull according to the present invention is attached to the entire upper width direction of the drawer main body and the front plate of the drawer main body, and has a generally U-shaped cross section with the front surface open at the upper plate, lower plate, and back plate. A handle is formed by forming concave grooves facing each other along its entire length between the tip of the lower plate and the middle of the back plate; The bulge formed at the lower end of the lever part in the upright state is integrally fixed to the rotating shaft, and the bulging part formed at the lower end of the lever part in the upright state is integrally fixed, and the bulge part between the back surface of the lever part eccentrically forward with respect to the rotating shaft and the concave groove of the back plate is a latch portion formed by attaching a leaf spring to the latch portion to elastically urge it forward, and fixing a latch cam that engages a pin attached to a cabinet side plate to a rotating shaft at a drawer side end position;
Even if the handle is thin, the lever part is eccentrically forward relative to the rotation axis to create a space between the back of the lever part and the back plate, so that the latch can be opened with a push motion. Each device can be attached so that it can be operated, and since grooves are provided across the entire length of the handle, cards such as business cards can be inserted between the grooves, except for the central part where the lever is located. In addition, by incorporating the latch part inside the handle, assembly processability, handling, maintenance and inspection, etc. are facilitated. At the same time, the open part on the front of the handle is Since it can be used as a space for operating the lever part of the latch, it is convenient because it can be used as a part of the handle and at the same time as a finger insertion space for operating the latch.
