Description

[Detailed description of the invention] The present invention relates to a removable plate, and in particular uses a single spring to lock the plate when it is stored and push it up when it is removed, and also improves the ease of assembling the lock lever and spring. It is in good condition and the lock lever operates reliably.

This type of removable hot plate has a plate that can be attached to and detached from the frame, and is provided with a so-called lock button to prevent the plate from coming off and rattling when stored. However, before the plate is stored, this button must be manually operated to enable locking, and after the plate is stored, it must be manually moved to the locked position, which is cumbersome and requires the same procedure as described above. If the plate is stored without doing this, there is a risk that the plate may rattle or come off due to vibration, causing burns, and if the procedure is incorrect, the locking device may be damaged. In addition, to remove the plate, move the lock button to release the lock as described above, but there is a disadvantage that it is difficult to remove the plate because you cannot hold the handle of the plate, and the locking device is exposed on the top surface of the frame. Because of this, cleaning the top surface of the frame is troublesome, and it also spoils the aesthetics and causes scratches from being pinched by fingers. Furthermore, although the locking device is composed of a locking lever and a spring, it has a drawback that it is difficult to assemble.

The present invention improves the various drawbacks mentioned above and will be described below with reference to the drawings. 1 has a circular storage recess 2 on the inside, stepped portions 3 on both sides at opposing parts of the storage recess, and a cutout groove 3a extending from the top to the bottom.
3a, and shaft holes 3b, 3b communicating with the outside at the bottom of the groove.
A frame-shaped (quadrangular) frame provided with recesses 4, 4, 5 has a pair of handles 6a on the opposing outer wall,
6b is a circular plate with an electric heater (not shown) buried in the bottom wall, and one of the handles 6a and 6b, 6a, has a wide grip portion 7 at the top that protrudes outward.
At the same time, a locking piece 8 is provided at the lower part of the grip part and projects outward at a predetermined interval S, and furthermore, a wide pressing part 9 is integrally provided at the lower part to form an F shape. . Reference numeral 10 designates the aforementioned plate locking device, which includes a locking pawl 13 provided with cylindrical protrusions 11, 11 on both sides of the approximately central portion and having an inclined portion 12 on one side.
The L-shaped lock lever 14 is provided so as to protrude into the storage recess 2, and the other side thereof is provided below the outer peripheral edge of the frame 1. Both sides of the L-shaped lock lever 14 are curled so that the cylinder of the lock lever 14 is formed approximately in the center. The lock lever 1 is fitted onto the protrusions 11 and 11 on one side.
A spring 16 is formed by bending a wire fixed to one side of the pressing body 4 and having the other side facing into the storage recess 2 and serving as the abutting portion 15 of the pressing body 9. The contact portion is bent into a wide shape. Reference numeral 17 denotes a stopper provided laterally across the lower part of one of the recesses 4 to prevent the contact portion 15 of the spring 16 from moving upward more than necessary. Reference numeral 18 indicates a controller provided at one corner of the frame 1 as a mounting mark, and reference numeral 19 indicates a pin.

Next, the assembly order of the lock device 10 will be explained. As shown in FIG.
Insert the protrusion into the cutout groove 3 from above.
a, 3a, and insert the pin 19 at the position where the cylindrical protrusion and the shaft holes 3b, 3b coincide. Thereafter, the stopper 17 is bridged and fixed within the recess 4 by appropriate means.

Next, the storage operation and removal operation of the plate 5 will be described. First, let's talk about the storage operation.
When the other handle 6b of the plate 5 is housed facing the other recess 4 of the frame 1 and one handle 6a is pushed down as shown in FIG. 7, the pressing part 9 of the handle 6a is pressed down. As a result, the spring 16 is loaded, and the other side of the lock lever 14 is pushed up as shown by arrow A in FIG.
is locked by the locking piece 8 of the handle 6a. That is, at this time, the spring 16 acts to lock the plate 5 as the pressing portion 9 presses. Regarding the removal operation of the plate 5, when the other side of the lock lever 10 is pushed down from below the frame 1 against the spring 16 as shown by arrow B in FIG. As the spring 16 is released, the contact portion 15 pushes up the other side of the plate 5 via the pressing portion 9, and the grip portion 7 protrudes from the upper surface of the frame 1.

As described above, the present invention includes a frame-shaped frame that has a storage recess inside and a recess that has a notch groove and a shaft hole on both sides in a part of the storage recess, and a frame that is detachably attached to the storage recess. A plate is provided with a locking piece projecting laterally and a pressing part projecting downward on the opposing outer walls, and a cylindrical projecting part is provided on both sides of the substantially central part, and one side is provided with a plate that engages and disengages with the locking piece. L with a locking claw to
A locking device consisting of a shaped lock lever and a spring which is curled on both sides of the substantially central part and fitted into the cylindrical protrusion, one side of which is fixed to the lock lever and the other side is an abutting part of the pressing part. Since the cylindrical protrusion is fitted into the cylindrical part through the shaft hole in the notched groove using a storage pin, the plate can be reliably stored and removed by the locking device. Of course, since the lock device is housed in the recess of the frame in a pre-assembled state, its assemblability is extremely simple. In other words, since the elastically deformable spring is fitted into the lock lever in advance, it may pop out when stored in a recess, or
If the lock lever is slowed down by coming into contact with the wall inside the recess, it will become smooth. Furthermore, since the spring itself is configured to serve as the abutment part of the pressing part, assembly is very easy.
