Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support frame for a work table which is mounted on a wall surface of a building, a machine tool or the like in at least one pair in parallel.

[0002]

2. Description of the Related Art When performing manual work, a work table with legs is used to obtain a position suitable for the work. The conventional work table is a simple desk type or a mobile type with a caterpillar, and is generally a non-foldable fixed type, but a folding type is also frequently used. In order to close the pair of legs that detachably receive the plate-shaped work table, both of them are pivotally attached to each other in an X shape by the vertical axis, and a pair of legs attached to both sides of the work table are provided inside. It is possible to cite the ones that are folded in.

[0003]

As described above, as described above,
A workbench was used for manual work, but it has the disadvantage of taking up space in the workplace even when it is not in use, and even if it is a foldable type, its folding and assembling operations are not easy, Moreover, in order to open the work space for other purposes, it is necessary to move and store the whole space, which is very inconvenient.

The present invention has been made in view of the above circumstances.
It is possible to lay down compactly on the object to be mounted such as the wall surface of the building or the side of the machine in the mounted state, and yet, despite the fact that the support of the work table is reliable, the folding and assembling operations are easy. The purpose is to provide a work frame support frame that is extremely simple.

[0005]

In order to achieve the above object, the present invention comprises a base frame vertically fixed to an object to be mounted and a work table pivotally supported on its upper end so as to be vertically swingable. The receiving frame, a driving link diagonally supported by the base frame and connected to the front end of the receiving frame so as to be swingable back and forth by a support pin, and a lower end pin pivotably supported by a lower end pin to the lower end of the base frame so that the tip is The driven link is pivotally mounted near the lower end of the main drive link, and in the posture of supporting the work table, the pivotal pin is inside the line connecting the support pin and the lower end pin, The work table support frame is constructed so that it can be rotated in the direction directly below, and the handle for rotating its pivot pin up and down is attached to the driving link on the outer side of the handle.

Regarding the means for fixing the base frame to the object to be attached, a dovetail-shaped slider that engages with a slide rail having an H-shaped cross section is attached to the back side of the upper end of the base frame, and fixed horizontally to the object to be attached in advance. In some cases, it may be configured so that it can be attached to the existing slide rail with a push screw.

[0007]

In the support posture of the work table, the pivot pin is inside the line connecting the support pin and the lower end pin,
The load acts to rotate the pivotal pin further inward, that is, to press the tip of the swing of the driving link against the base frame, and by that action, the driven link also pushes up the driving link, and as a result, Since the state in which the driving link is supported by the base frame by the tip end is securely held, the receiving frame is securely held even if the driving link is free with respect to the base frame.

[0008] From the support of the work table, when closing, the handle of the drive link is taken and pulled, and the pivot pin is brought to the lower end by leaving it on the track centered on the lower end pin. Then, the receiving frame and the driven link follow the driving link, the receiving frame overlaps with the base frame, and the driving link and the driven link are closed under the receiving frame.

[0009]

Embodiments of the present invention will now be described with reference to the drawings.

The drawings show one embodiment, in which a supporting frame F of the work table includes a base frame 1, an upper receiving frame 2 for receiving the work table T, and a driving link 3 for supporting the same. Further, it comprises a driven link 4 at the lower end for supporting the work table T.
A link mechanism capable of taking a posture for supporting (FIGS. 1 and 2) and a folded posture (FIG. 3) is configured.

Channel members are used for each member constituting the link mechanism in order to secure the strength and to obtain the point of overlapping or fitting in the combination, and the base frame 1 and the receiving frame 2 are used. The same members that overlap on the open surface are used (see FIG. 3), and the width of the driven link 4 is set in the base frame 1 and the driving link 3 is set in the driven link 4.

The base frame 1 is vertically fixed to a mounting object B such as a pillar of a building or a working machine, and has a U-shaped opening at the upper end for fixing to the mounting object B. A narrow, so-called dovetail-shaped slider 5 is fixed laterally and is equipped with a push screw 7. In the case shown in the figure, in order to mount the support frame F on which the attachment object B is a pillar, a slide rail R having an H-shaped cross section is fixed over the plurality of pillars. Therefore, when mounting the support frame F, the slider 5 is attached to the slide rail R.
It is fitted in from the end and fixed with a set screw 7 at a predetermined interval.

In order to firmly attach the slider 5 to the base frame 1, reinforcing members 9 and 9 formed of angles are screwed to both sides of the base frame 1, and the slider 5 is screwed to both of them. A female screw 11 for screwing the push screw 7 is welded to both the reinforcing members 9, 9. Further, in order to stabilize the attachment, a contact member 13 is screwed to the base frame 1 under the slider 5. The slide rail R has a vertically long portion to be applied to the attachment object B so that it can be firmly screwed to the attachment object B, and the abutment member 13 is attached to the elongated lower end portion.
Are in contact with each other.

The receiving frame 2 receives the work table T horizontally (see FIGS. 1 and 2), and its base end is the upper end of the base frame 1 so as to swing up and down with its position as a return point. Is pivotally supported by the department. However, the support pieces 15 that fit in both are screwed to the base frame 1 so as to overlap with the base frame 1, and the receiving frame 2 is attached to the protruding portion thereof.
A base pin 17 that pivotally supports is attached.

The driving link 3 serves as a so-called support rod of the receiving frame 2 with respect to the base frame 1, and is pivotally supported by a support pin 19 at its tip end to follow the receiving frame 2. . Regarding the lower end, the tip 20 is free to be separated from the base frame 1, but in the support posture of the work table T, the tip 20 is inclined so as to abut and stably support the bottom surface of the channel of the base frame 1. It is formed on the end face. Also, in the support posture,
Since the lower end of the driving link 3 fits inside the base frame 1 in this way, a safe and reliable support function that does not laterally shift is exhibited. A handle 21 for manual operation is attached to the driving link 3 at an intermediate length portion.

The handle 21 is formed in a dogleg shape at its base end so that it can be pulled out from the state where it overlaps with the driving link 3 (see the alternate long and short dash line in each figure), and is connected to the driving link 3 by a pin. In the pulled-out state, the drive link 3
So that it stops at a right angle to the
Is formed. Note that friction with the inner surface of the driving link 3 is used as a means for maintaining the closed state. Without using the handle 21, when the operation is performed while holding the driving link 3 directly, the hand is caught between the driving link 4 and the driven link 4 (see FIG. 3), and when the assembling operation is performed, the receiving frame 2 In the meantime, there is a risk of getting your hands caught.

The driven link 4 supports the supporting body of the driving link 3, and is connected to the lower end of the base frame 1 by a lower end pin 25 so as to be vertically swingable, and the tip of the swing is pivoted to the driving link 3. They are connected by a wearing pin 27. Therefore, the pivot pin 27 takes a circular orbit M centered on the lower end pin 25. Therefore, with respect to the position of the pivot pin 27 in the support posture (see the solid lines in FIGS. 1 and 2), the circular orbit M is inside the position of the dead point P, so to speak, intersecting the line connecting the support pin 19 and the lower end pin 25. The pivot pin 27 is attached near the base end of the drive link 3 so that Therefore, the driven link 4 is provided with a cutout groove 28 through which the bottom of the channel is pulled out so that the tip end portion is pulled out from the pivotal pin 27 of the driving link 3.

Next, looking at the movement of the receiving frame 2, when the pivoting pin 27 rotates downward from the position of the support body, it reaches the point Q aligned with the support pin 19 and the lower end pin 25 in a straight line. The receiving frame 2 rises (dashed line in FIG. 2) and turns downward with the upper limit as the upper limit (dashed line in FIG. 3), and the receiving frame 2 overlaps the base frame 1 at the lower limit of the pivot pin 27 (solid line in FIG. 3). . At this time, the base end pin 17, the support pin 19, and the pivot pin 27 are substantially aligned with each other, and the driving link 3 is located at the base end portion of the receiving frame 2.
It is housed inside and droops in its extension direction, and the driving link 3 and the driven link 4 form a closed and compact posture.

In order to assemble from the closed state to the support body, by grasping the handle 21 and pulling up the driving link 3, as shown in FIG. 1 and FIG.
Press the lower end of the to the base frame 1. Then, the driving link 3 and the driven link 4 are bent inwardly in a V shape by the pivot pin 27, and the driving link 3 is pressed against the base frame 1 at the inner tip by the force of further bending due to the load. Since the support posture is held stably,
The driving link 3 never comes off.

It should be noted that the upper surface of the receiving frame 2 and the support piece 15 are arranged so that the work table T does not shift or rattle.
Cushion members 29, 29 on the seat also serving as anti-slip are adhered to the upper surface of the sheet.

[0021]

As described above, according to the supporting frame of the working table of the present invention, the following excellent effects are obtained.

[0022] Compared with the case where a workbench is permanently installed, it can be used for a work area in comparison with the case where a workbench is permanently installed, because it can be placed on an object to be mounted such as a wall surface of a building or a side surface of a machine in a compact state. Can be expanded. Also,
Compared with the case where the workbench is moved, it is possible to save the labor of moving and improve workability.

Despite the reliable support of the work table, the folding and assembling operations are extremely simple,
The operation can be easily performed by simply moving the driving link. Moreover, since the handle attached to the drive link is operated, there is no risk of the hand being caught and it is safe.

With respect to the reliability of the support body, since it is necessary to adopt a mechanism for shutting down, even if the tip of the swing of the driving link is free with respect to the base frame, as the load is applied, the driving link causes the base link to move the driving link to the base frame. The receiving frame securely supports the receiving frame so that the receiving frame is pressed against.

With respect to the fixing means for fixing the base frame to the object to be attached, when a slider which engages with the slide rail is provided (Claim 2), it is not only easy to equip the object to be attached, but also the length of the work table is increased. The spacing can be easily adjusted accordingly.
