Description

[Detailed Description of the Invention] The present invention relates to a push-button type planar bundle device in which a bundle, which is recessed in a case when not in use, is projected and rotated to a graspable position by operating a push button.

In the conventional push-button flat bundle device,
As shown in Japanese Patent No. 1102, the push button for operating the protrusion and rotation of the bundle is attached to the case body that houses the bundle.

Because the pushbutton itself cannot be omitted due to its functionality, no matter how close the pushbutton mounting section is placed to the bundle storage section, there is a limit to the reduction in length and size of the case. .

In addition, in the above-mentioned conventional flat bundle device, the bundle is immersed and held in the case only by the repulsive force of the leaf spring inserted between the back of the bundle and the inner bottom of the case. When gravity or vibration is applied to the plate, the force that forces it to rotate upward in the upward protruding direction exceeds a certain level, and when the end of the plate spring crosses the dead center, the bundle completely protrudes from the case and the door closes. ended up opening.

Therefore, an object of the present invention is to provide a push-button type flat bundle device that allows the case to be significantly downsized and that does not cause unexpected bundle protrusion or door opening due to vibration or the like.

The planar bundle device of the present invention will be described below with reference to the drawings.
The push button 6 is urged to rotate in the protruding direction by the spring 4, and is pivoted to the lower end of the bundle 2 by a second pivot 5 parallel to the first pivot 3. The latching protrusion 7 is provided in a protruding manner with the position shifted further downward, and the inner bottom wall 8 of the case 1 is provided with a receiving part 9 to which the latching protrusion 7 engages and disengages. Push the push button 6 in the direction of the second spring 1.
It is rotationally biased by 0.

In the illustrated embodiment, the first pivot 3 is arranged horizontally and passes through the left and right side walls 11, 12 of the case 1, as in the prior art device.

The winding portion 4a of the first spring 4 shown in FIG.
is fitted in.

The actuating protrusion 17 protruding from the back of the upper end of the bundle 2 is connected to the case back wall 14 by a third pivot 13 perpendicular to the first pivot 3.
The latch plate 15 is engaged with a passive hole 16 of a latch plate 15 pivotally connected to the latch plate 15 .

Therefore, in the counterclockwise direction in FIG.
When the latch plate 15 rotates and protrudes from the case 1, the latch plate 15 is pushed by the actuating protrusion 17 and rotates, and is detached from a receiving part (not shown) on the fixed frame side of the box body.

Insert the case 1 into the rectangular receiver (L19) drilled in the door 18,
The case 1 is attached to the door 18 by screwing the screw 21 inserted through the washer plate 20, which has a U-shaped cross section, into the threaded hole 22 in the case back wall 14, and tightening the front end surfaces of both legs of the washer plate 20 to the back of the door.
is easily installed.

A recess 23 whose front and lower surfaces are open as shown in FIGS. 11, 14, and 15 is formed in the box-shaped enlarged portion at the lower end of the bundle 2, and the main portion of the push button 6 is shown in FIG. 3. It is accommodated in this recess 23 as shown in FIG.

The second pivot shaft 5 passes through the left and right side walls 24 and 25 of the recess 23, and is connected to the winding portion 1 of the second spring 10 shown in FIG.
0a is fitted onto the second pivot 5.

As shown in FIGS. 17, 19, and 20, two bearing pieces 26 and 27 are protruded from the lower end of the back surface of the push button 6. As shown in FIGS.

As shown in FIGS. 9 and 10, the receiving portion 9 is constituted by a horizontally long square hole, and the latching protrusion 7 is constituted by a horizontally long protrusion having a substantially V-shaped longitudinal section.

As shown in FIG. 19, the front surface 7a of the latch protrusion 7 is formed of an arcuate surface centered on the shaft hole 28 of the bearing piece, and when the push button 6 is pressed, the latch protrusion 7 The rear surface 7b of the bifurcated latching protrusion 7, which is designed not to contact the edge of the receiving portion 9, is configured with a 45° inclined surface, which allows the push button 6 to automatically rotate when the bundle is stored. It is on the operation cam surface.

This push button 6 has a built-in lock plate 29 for locking the push button 6 to the case 1.

This locking plate 29 is rotatably fitted into the vertically long opening 30 of the push button 6, and its tip 29a is inserted into the receiving hole 31 formed in the right side wall 12 of the case through the vertically long hole 31 formed in the right side wall 25 of the recess. It engages and disengages from the hole 32.

The base end 29b of the lock plate is provided with a lock hole 33 for receiving the rotation operation plate.

The push button is provided with a protruding guide rod 34 passing through the lock hole 33, and a spring washer 35 is interposed between the lock plate 29 and the push button 6.

In this planar bundle device, when the push button 6 is pressed against the rotational bias of the second spring 10, the push button 6 is moved so that its latching protrusion 7 is in the receiving position on the case side, as shown in FIG. The bundle 2 is rotated to the position where it escapes from the part 9, thereby unlocking the bundle 2 from the case 1.

Therefore, the bundle 2 is biased by the first spring 4, and as shown in FIG. 5, the bundle 2 protrudes more than the case 1.

Due to this protruding rotation, the latch plate is rotated as described above, the door 18 is unlocked from the fixed frame, and the door 18 is unlocked from the fixed frame.
8 can be opened.

When storing the bundle 2 in the case 1, as shown in FIG. is automatically rotated in the retracting direction against the bias of the second spring 10.

When the bundle 2 is fully stored, the locking protrusion 7 that has come into sliding contact with the inner bottom wall 8 of the case enters the receiving part 9 again, and thus the bundle 2 is locked against the case 1 again. will be stopped.

As described above, in the push-button flat bundle device of the present invention, the push-button 6 is pivotally attached to the lower end of the bundle 2, and the case 1 has a receiving portion 9 on which the latching protrusion 7 of the push-button 6 engages and disengages. , the length of the case 1 can be significantly shortened and the size can be reduced compared to the conventional push-button flat bundle device in which the push-button mounting section is provided adjacent to the bundle storage section. It can be done.

Therefore, push-button type flat bundles, which are most convenient in practice, can be used even in small power distribution boards where push-button type flat bundle devices cannot be installed because the space for installing bundle devices is narrow and limited. is now possible.

In addition, in the planar bundle device of the present invention, the push button 6 is pivotally connected to the lower end of the bundle 2 by a second pivot 5 parallel to the first pivot 3, which connects the upper end of the bundle 2 to the case 1.
A latching protrusion 7 is provided at the lower end of the push button 6 at a position shifted downward from the second pivot 5, and a receiving part 9 to which the latching protrusion 7 engages and disengages is connected to the inner bottom of the case 1. Provided on the wall 8, the hanging protrusion 7
Since the push button 6 is rotationally biased by the second spring 10 in the direction in which the bundle 2 enters the receiving portion 9, unexpected protrusion of the bundle 2 and unexpected opening of the door 18 are impossible.

That is, even if gravity is applied to the latch plate 15 that is interlocked with the bundle 2, vibration is applied, and a biasing force is applied to rotate the bundle in the projecting direction, the second pivot 5 and Depending on the arrangement of the latching protrusions 7, the biasing force is converted into a force that causes the latching protrusions to enter the receiving portion 9 and rotates the push button 6 in a direction to maintain engagement between the two. That's what happens.

The external biasing force acting in this manner and the second
Due to the cooperation of the inherent biasing force of the spring 10, the engaged state of the locking protrusion 7 and the receiving part 9 is accurately maintained, and the bundle 2 does not rise or protrude from the case 1.
