Description

[Detailed description of the invention] Industrial application field This invention is a device that is placed next to the OA equipment table, etc., to store supplies used in each OA equipment (for example, floppy sticks, printing ribbons, printing paper, etc.). This relates to a braking device for a side table that is placed on a table.

BACKGROUND ART A conventional side table of this type is Utility Model Application No. 1982-82508. This side table is
A recess is provided at one end of the top plate attached to the top of the table body, and the grip rod is moved up and down from the grip rod sliding opening in this recess toward the wheels placed on both sides of the bottom of the other end of the table body. It was inserted so that it could move. When the grip lever is pushed down into the table body, the tip of the grip lever comes into pressure contact with the circumferential surface of the wheel to brake the wheel. Also, when the upper body of this grip lever is pulled up to the outside of the top of the table body,
The tip of this grip lever moves away from the circumferential surface of the wheel and the previous braking is released, so from this point on, use the grip lever pulled up as described above as a hand push tool.
The side table was configured to be moved to a desired location.

Problems to be Solved by the Invention Due to the above configuration, conventional side tables of this type have the following problems.

(1) When the grip lever was pressed down to brake the wheels, there was no means to ensure that the grip rod was pressed down. Therefore, when a heavy object is placed on the top plate, the weight weakens the braking force on the wheels, and there is a risk that the side table may move inadvertently.

(2) There was also no locking mechanism for the drawer that stored supplies. Therefore, the drawer may open while the side table is being moved, or an outsider may open the drawer without permission and take out the supplies inside.

Means for Solving the Problems This invention solves the problems of the prior art described above, and provides a push-down guarantee for the depressed grip lever, and selectively provides a locking function for the drawer. Therefore, it is an object of the present invention to provide a braking device for a side table that can enhance the safety of the side table and improve the ability to manage supplies against outsiders taking them out. The feature of this invention is that a recess is provided at one end of the top plate attached to the upper part of the table body, and the grip lever sliding opening of this recess is placed on both sides of the lower part of the other end of the table body. In a side table in which a grip lever that brakes the wheel is inserted so as to be able to move up and down, a wheel stopper that brakes the wheel is placed above and below the position that the grip rod reaches when pressed down. The drawer is arranged to be swingable, and a lock release plate that lifts the convex piece that locks the drawer is placed on the lower side of the same reaching position as described above so that one end of the drawer can be lowered by its own weight. The upper end of the lock plate with the piece attached to its lower end is rotatably connected to the other end of the lock rod, which communicates with the outside and has a locking tool attached to its other end.

Function When using a side table equipped with a braking device configured as described above in a department adjacent to OA equipment as a side table, push the grip lever down into the table body to the height of the top plate. A wheel stopper is arranged so that it can come into contact with the upper part of the position reached when the grip lever is pressed down, and the contact side rises due to the swinging force caused by the pressing force when it makes contact, and the opposite side moves into a see-saw shape. As it descends, the descending tip comes into pressure contact with the circumferential surface of the wheel and brakes the wheel,
This allows the side table to come to a complete stop. In addition, at the bottom of the position reached when the above-mentioned grip lever is pressed down, there is a lock release plate that lifts the convex piece that locks the drawer, and it comes into contact with the above-mentioned push-down operation. Since one side is lowered and the other side is raised like a seesaw, the protruding pieces are simultaneously lifted on this rising side to unlock the drawer, thereby allowing the supplies in the drawer to be removed. Next, when moving the side table, pull up the grip that had been pushed down into the table body.The wheel stopper, which is released from contact with the grip, releases the brake on the wheels, so at this point This side table can be moved to the next target position by using the handle that has been pulled up from the side table as a push tool. At the same time, when the grip lever is pulled up, the protruding piece descends to its original position, so the drawer is completely locked while the side table is being moved, and the inconvenience of the drawer opening during movement can be easily prevented. Even when the side table is not moved, if you apply the locking operation to the lock plate via the locking device, the drawer will remain locked unless unlocked using the key, making it impossible for outsiders to remove supplies from the drawer. can be completely prevented.

Embodiments Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

First, to explain the structure, as shown in FIGS. 1 to 5, a top plate 2 is attached to the top of a table body 1 which is a rectangular cube with a hollow interior. A recess 3 having a predetermined width orthogonal to the longitudinal direction is provided at one end of the outside of the top plate 2, and a grip lever sliding opening 4 formed on both sides of the recess 3 is provided. Between the inner sides and the outer recess 3, there is In order to brake the wheels 6 on the left and right sides, the grip lever 5, which is formed by bending a series of belt-shaped plates and is formed into a U-shape in plan view, has an external push-down and pull-up operation in the recess 3. In the side table inserted so as to be able to move up and down in an oblique direction, the top side of the left and right position that the tip of the grip rod 5 reaches during the push-down operation has a function of braking the wheels 6 as described below. A wheel stopper 9 is arranged to be swingable. In addition, the grip rod 5 mentioned above
The distal end portion is formed into a tapered shape on the upper edge side, and has a stepped notch on the lower edge side.

The wheel stopper 9 described above is formed as follows. In other words, as shown in Figure 2,
Inside the table body 1 at the left and right positions where the wheels 6 are arranged, a band-shaped plate of a predetermined width is bent downward into a U-shape at the top, and its inner surface is lowered to near the bottom and placed inside the wheel axle 7. A stopper mounting plate 8 serving as a supporting wall surface is fixed to the wall surface of the main body 1 at this position. In the horizontally elongated space above the stopper mounting plate 8, a vertical section is formed in a U-shape, and one end thereof protrudes obliquely toward the rear side of the stopper mounting plate 8, and a roller is attached to the tip. A wheel stopper 9 to which a wheel stopper 10 is attached is inserted so as to be able to swing up and down about a spindle pin 12 that passes through the upper part of the stopper mounting plate 8. In this case, a dogleg-shaped push spring 13 is fitted onto the support shaft pin 12, and due to the supporting force of the push spring 13, the inclined end side of the wheel stopper 9 on which the roller 10 is fitted is fixed as described above. The tip of the gripping rod 5 protrudes upwardly above the position reached when the gripping rod 5 is pressed down. In addition, a braking convex portion 11 protrudes downward from the bottom surface of the tip of the wheel stopper 9 on the opposite side, and when the roller 10 side is raised by pressing down the grip lever 5, this convex portion 11 moves in a see-saw shape. It descends and comes into pressure contact with the circumferential surface of the wheel 6 located directly below,
The wheel 6 is thus configured to be braked.

Furthermore, when the above-mentioned gripping rod 5 is pressed down, one end of the gripping rod 5 is attached to the lower side of the left and right positions that the tip reaches, in order to lock the drawer 28 in the table main body 1.
The lock release plate 16 is bent into a letter-shaped surface and the other end is formed into a strip-shaped flat surface, and the L-shaped vertical surface near the other end is loosely fitted into a pin 17 inserted into the external wall surface of the main body 1 on each side. As a result, when the tip of the gripping rod 5 reaches the other end when pressed down, the other end pressed by the tip descends, causing the one end to become seesaw-like. rise,
As a result, the convex piece 19 shown below is pushed up. Note that this lock release plate 16 is
When not receiving the pressing force from the tip of the gripping rod 5,
One end of the L-shaped plate is configured to descend around the pin 17 due to its own weight. At this time, one end side of the lock release plate 16 is connected to a rail board 14 mounted in a protruding manner inwardly of the main body 1 on each side.
It is configured to abut against a stopper rubber 15 located on the upper surface of one end side of the holder so as to maintain a substantially horizontal position.

The convex piece 19 described above is constructed as follows. That is, as shown in FIGS. 2 and 3,
This convex piece 19 is vertically movably attached to a position directly above the bent portion 20 of the lock plate 18 whose lower end is vertically slidably inserted into a hole in the upper surface (not shown) of the rail board 14 described above. One side of this protruding piece 19 is protruded toward the inside of the main body 1 at a right angle, and this protruding piece comes into contact with a stopper 29 of the drawer 28, which will be described later, to stop the drawer 28 when it is stored. Configured to lock. This convex piece 19 corresponds to the above-mentioned lock release plate 16.
When the drawer 28 is pushed up by the rocking motion, the drawer 28 rises together with the lock plate 18.
The lock is configured to release the lock on the stopper 29. Note that casters 25 are attached to the bottom of the main body 1 below where the locking tool 21 is located.

The left and right lock plates 18 having the above-mentioned convex pieces 19 attached to their lower ends are formed into belt-like plates whose upper ends extend to a position close to the top plate 2. When the protruding piece 19 receives a push-up operation from the lock release plate 16, it is configured to rise integrally. Further, at the upper end of the lock plate 18, a lock rod 22 having a length from this position to one end side in the top plate 2 corresponding to the tip of the recess 3 is provided to open the locking tool 21 attached to the above one end side communicating with the outside. , are connected so that the lock plate 18 can be moved up and down by turning the lock plate 18 when the lock is locked.

Main body 1 at a position close to the above locking rod 22
A pin 24 is attached to the left and right walls of the interior, and a grip lever stopper 23 having a roller at the lower end stably supports the grip lever 5 by the supporting force of a spring. In this case, on the side surface near the tip of the gripping rod 5, a sheath plate 30 is installed in a fitted manner in the direction in which the gripping rod 5 is pulled up, and on one end side of this sheath plate 30. An abutment 31 is provided for stopping the lifting operation of the grip lever 5 at the time of contact.

Further, as shown in FIGS. 3 and 4, vertical original rails 26 are provided on the left and right sides of the main body 1 from the rail board 14 into which the lower end of the lock plate 18 is loosely inserted, to a position close to directly above the caster 25. is installed horizontally, and on this base rail 26 is a pull-out rail 27 that extends and contracts in the front and back direction via small steel balls.
It is arranged so that it can run integrally with the drawer 28 placed on this rail 27. There are lock plates 1 on the left and right sides near the rear end of the drawer 28.
A stopper 29 for locking the drawer 28 is attached by a convex piece 19 integral with the drawer 8, and the whole constitutes a braking device for the side table.

When using a side table equipped with a braking device with the above configuration as a side table by placing it in a department adjacent to predetermined OA equipment, when moving it to this department, it can be pulled up outside and used as a hand tool. When the grip rod 5 is pushed down into the main body 1 to the height of the top plate 2, the wheel stopper 9 can come into contact with the upper side of the position reached by the tip of the grip rod 5 being pushed down. placed in the state.
Due to the pressing force of the tapered edge at the time of contact, the roller 10 side of the wheel stopper 9 rises around the spindle pin 12, and the braking convex portion 11 on the opposite side descends in a see-saw manner. Since the braking convex portion 11 comes into pressure contact with the circumferential surface of the wheel 6 at that position and brakes the wheel 6, the side table can be completely stopped.

A convex piece 1 for locking the drawer 28 is located on the lower side of the position reached when the grip lever 5 is pushed down.
The lock release plate 16 that pushes up the lock 9 is located,
When the gripping rod 5 is pressed down, the other end of the strip plate that is in contact with it descends, and the opposite end of the strip rises like a see-saw. The convex piece 19 that was locking the drawer 28 is lifted at the same time as this one end side rises, and the drawer 28 is unlocked. Therefore, the desired supplies can be removed from the drawer 28 at this point.

Next, when the side table is moved after supplying supplies at this position, the grip lever 5, which had been pushed down into the table body 1, is moved so that the abutment 31 on the tip side is Saya board 30
When you pull it upwards to the outside until it touches the
The wheel stopper 9 released from the contact at the tip of the gripping rod 5 releases the brake on the wheel 6 directly below, so the gripping rod 5 is pulled up from this point.
The side table can be smoothly and easily moved to the next target position by making it into a stable hand tool due to the resilient pressure support force of the gripping rod stopper 23.

Furthermore, at the same time as the grip lever 5 is pulled up, the convex piece 19, which had been pushed up through the lock release plate 16, descends to its original position together with the lock plate 18, so that the side table is not moved. The inner drawer 28 is completely locked as it is prevented from advancing by the protruding piece 19 which has been lowered to its original position as described above. Therefore, the inconvenience of the drawer 28 opening while the side table is being moved can be reliably prevented.
Even when the side table is not moved, by inserting a key (not shown) into the locking device 21 and turning the internal locking rod 22 in a specified direction through this key, the convex piece 19 connected to the locking rod 22 can be opened.
A locking operation is given to the attached locking plate 18, whereby the locked state of the drawer 28 is completely maintained unless unlocked using a key, and an outsider cannot access the drawer 28.
This makes it easy to prevent supplies from being taken out.

Effects of the invention This invention provides a recess on one end side of the top plate attached to the upper part of the table body, and from the grip lever sliding opening of this recess to the wheels arranged on both sides of the lower part of the other end of the table body. In a side table into which a grip lever that brakes the wheel is inserted so as to be able to move up and down, a wheel stopper that brakes the wheel is placed on the upper side of the position that the grip rod reaches when it is pressed down. On the lower side of the same reaching position as mentioned above, a lock release plate that lifts the convex piece that locks the drawer is arranged so that one end side can be lowered by its own weight, and the above-mentioned convex piece is The lock plate is attached to the lower end, and the upper end of the lock plate is rotatably connected to the other end of the lock rod, the other end of which is connected to the outside and has a locking tool attached thereto. Therefore, the pressed down grip lever is pressed by the wheel stopper on its tip side due to the bullet-shaped support, the clamping force due to its own weight applied to one side of the lock release plate, and the load from the lock plate applied to this lock release plate, and further With the pressure contact force by the gripping rod stopper on the upper side,
It is guaranteed that the grip lever is pressed down firmly, and the locking mode for the drawer inside the main body is as follows:
Not only when the grip lever is pushed down, but also when the grip lever is pulled up, complete locking is selectively ensured by key operation on the locking device, increasing the safety of this type of side table and improving the supply. This has the effect of providing a control function to prevent items from being taken out by outsiders.
