DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work table (work table, work table, test table, work table) used in a laboratory or a work room for chemical, physical, engineering, etc.

[0002]

2. Description of the Related Art As a work desk used in a laboratory, a support frame having the same width as the width of the top plate is erected on a back portion of the top plate supported by legs, and a power supply is provided on a front portion of the support frame. There is a type in which various devices and equipment such as a power outlet, a water tap, and a gas discharge port are attached. Various media such as gas, water, electricity, and communication signals for causing the devices and devices to function are supplied to the devices and devices via media supply media such as pipes and cords.

[0003] The support frame generally includes a pair of right and left columns and a plurality of upper and lower main horizontal rails fixed to the left and right columns. Devices and equipment are fixed to the main horizontal rails with screws. Classes and cords pass through the space between the upper and lower main rails. On the other hand, many sources of media, such as electricity, water, and gas, are outside the laboratory, and cords and pipes for supplying them are drawn into the laboratory and collected together in walls and walls. It is often pulled out to the work desk from the floor or the ceiling.

[0004] In this case, the work desk is often installed with its back surface in close contact with the wall, or two work desks are installed back to back. Cords and pipes cannot be drawn into the space between the main crossbars from behind the support frame. For this reason, under such an installation form, conventionally, cords and pipes laid on the floor, wall, back of the ceiling, etc. are drawn into the support, and the space between the horizontal hole opened in the support and the upper and lower main horizontal rails is conventionally used. I was trying to pull it out.

[0005]

SUMMARY OF THE INVENTION The device
The work desk in which the devices are mounted has advantages that the space can be effectively used, and that the devices and devices are easy to use. However, in the conventional work desk, it has been troublesome to change the mounting position of the device / equipment, or to newly install or add it. In other words, in the past, cords and pipes were passed through the columns and then drawn out to the space between the upper and lower main crossbars, so wiring and piping work was extremely troublesome, and the capacity of the cords and pipes was stored. However, since the devices and devices are attached to the main cross rail by screwing one by one, the work of mounting and removing the devices and devices is troublesome.

An object of the present invention is to solve this problem.

[0007]

According to the present invention, a support frame rising above the top plate is disposed at a rear portion of the top plate,
The above object has been achieved by improving the support frame in a work desk in which devices and equipment for experiments and the like are mounted on the front surface of the support frame via a panel.

[0008] The support frame of the present invention includes at least two right and left columns and at least two upper and lower main cross beams which are fixed between the columns in a horizontal posture. In each main cross rail, through holes through which pipes, power cords and the like can be vertically inserted are formed at appropriate intervals along the longitudinal direction. Further, each main horizontal rail is provided with an engaging portion such that a locking piece or a locking claw formed on the panel can be detachably attached from the front along the longitudinal direction of the main horizontal rail. It is provided to extend continuously or intermittently.

[0009]

According to this structure, the cords and pipes can be inserted into the through holes of the main horizontal rail from the up and down direction. Wiring and piping work can be easily performed even when the devices are installed back to back. Moreover, since a large number of through holes can be formed along the longitudinal direction of the main horizontal rail, the freedom of wiring and piping positions can be greatly improved without increasing the front and rear width dimensions of the support frame, and the cords and the like can be improved. The storage capacity of pipes can be significantly increased. Further, since the devices and devices are attached to the main horizontal rail via detachable panels, attachment and detachment of the devices and devices can be easily performed.

Therefore, according to the present invention, wiring and piping work can be easily performed in mounting various devices and devices on the support frame of the work desk, and the position of the devices and devices can be easily changed and new installation and expansion can be easily performed. Can be easily performed. Claim 2
With this configuration, plumbing and wiring work can be performed with the top plate removed, making it easier to install, change, and expand devices and equipment on the work desk. There is.

Further, according to the third aspect of the present invention, the panel can be mounted at any position along the left and right direction of the main horizontal rail, so that the freedom of setting and changing the position of the device / equipment is improved. It can be further improved. In addition, since the insertion of the locking piece of the panel into the engaging groove of the main horizontal rail is guided by the upper and lower lips, the work of mounting the panel is simple.
In addition, since the engaging groove is formed in the protruding ridge protruding forward from the main horizontal rail, it is possible to prevent the locking piece of the panel from hitting the pipes and cords passing through the inside of the main horizontal rail. Therefore, there is an advantage that the pipes and cords are not damaged.

By the way, since the sizes and arrangement positions of the devices and equipment to be mounted on the support frame are various, it is desirable that the size and the installation position of the panel can be freely selected.
This request can be met by the invention of claim 4. That is, according to the fourth aspect of the present invention, the auxiliary horizontal rail is attached to an arbitrary portion of the support frame by using the partition frame mounted using the through hole of the main horizontal rail, so that the panel of various sizes is provided. Can be attached to any part of the support frame. Therefore, devices and apparatuses having different sizes can be efficiently and simply arranged at desired positions.

[0042] Partition Frame For example, as shown in FIGS. 17 and 18, the partition frame 75 is formed in a shallow groove shape with a width substantially the same as the front and rear widths of the horizontal rails 24 and 76. At the upper and lower ends of the partition frame 75, notches 77 are formed to be fitted into the opening edges of the through holes 25 in the horizontal rails 24 and 76. Since the width dimension of the partition frame 75 is smaller than the diagonal dimension of the through hole 25, the upper and lower ends of the partition frame 76 are vertically inclined as shown in FIG. It can be inserted into the through hole 25 of the horizontal rail 24.

The groove 77 can be fitted and engaged with the opening edge of the through hole 25 by fitting the upper and lower ends into the through hole 25 and then rotating about the axis thereof. As a result, the partition frame 75 cannot move forward and backward and cannot fall,
Placed between. It is preferable that the partition frame 75 is fitted with the groove 77 into the edge of the through hole 25 and then slid as shown by an arrow A in FIG. Forming the partition frame 75 in a groove shape (channel shape) is advantageous in that it is hard to bend even if it is thin and lightweight, and has high strength.

When the partition frame 75 is mounted, as shown by a solid line in FIG. 18C, the partition frame 75 is inserted into the through hole 25 from the space between the upper and lower main horizontal rails 24 by being inclined when viewed from the front. Alternatively, as shown by a dashed line in the figure, the upper and lower cross rails 24 may be sequentially inserted downward from the through holes 24. The partition frame 75 is provided with screw holes 79 for fastening the first bracket 27 of the auxiliary horizontal rail 76 with screws 78 at regular intervals in the vertical direction. Partition frame 75

It is preferable that the dimension in which the partitioning frame 75 enters the horizontal rails 24, 76 is as small as possible (in order not to disturb the pipes 2 and the cords 3). Further, the partition frame 75 does not necessarily need to be formed in a groove shape, but may have another cross-sectional shape such as a plate shape. . Usage Mode FIG. 19 shows a usage mode of the partition frame 75 and the auxiliary cross rail 76. In this use mode, the upper main cross rail 24 and the middle main cross rail
24, two partition frames 75 are attached, the auxiliary horizontal rail 76 is fastened between the left and right partition frames 75, and the small horizontal panel 15 is mounted using the auxiliary horizontal rail 76.

Further, a partition frame 75 is also attached to a portion on the right side between the middle main horizontal rail 24 and the lower main horizontal rail 24, and an auxiliary horizontal rail 76 is provided between the partition frame 75 and the right column 23. And fix the panel 15 with a small height using the auxiliary horizontal beam 76.
They are installed one by one. FIG. 20 shows still another use mode. In this use mode, a first partition frame 76a is attached between the upper and lower main horizontal rails 24, and the first auxiliary horizontal rail 76a is fastened to the first partition frame 76a and the support column 23. A second partition frame 75 is attached between the first horizontal rail 24a and the first auxiliary horizontal rail 76a, and between the upper main horizontal rail 24 and the first auxiliary horizontal rail 76a.

As can be easily understood from the above description, various combinations of the partition frames 75, 75a, 75b and the auxiliary horizontal rails 76, 76a, 76b make it possible to mount panels of different sizes on the front surface of the support frame 14. 15 can be mounted in a free layout, and as a result, devices / equipments having different sizes can be efficiently arranged at desired portions. And partition frame 7
No special members are required for 5,75a, 75b because they are mounted using the through holes 25 of the horizontal rails 24,76. Therefore, the structure is not complicated.

If the pitch of the screw holes 79 in the partition frame 75 is set to a dimension that is a fraction of the pitch of the screw holes 26 in the support column 23, the two partition frames 75, 75a, 75b are supplemented. When the horizontal rails 76, 76a, 76b are fixed across, the height of the auxiliary horizontal rails 76 can be changed in small increments. Needless to say, it is not necessary to attach devices and equipment to all panels 15.

(7) Seventh Embodiment (FIG. 21) In the seventh embodiment shown in FIG. 21, the fitting portions 75a formed at the upper and lower ends of the partition frame 75 are inserted into the through holes 25 of the horizontal rails 24 and 76. By being fitted, the partition frame 75 is held so as not to be displaced in the front-rear direction and the vertical direction. The fitting portion 75a may be formed on one of the upper and lower ends of the partition frame 75, and the groove 77 of the sixth embodiment may be formed on the other.

The structure for mounting the auxiliary cross rail using the partition frame as in the sixth embodiment or the seventh embodiment is widely used not only for a support frame for a work desk but also for a frame device such as a display device. Applicable. (8). Others While the embodiments of the present invention have been described above, the present invention can be embodied in other various forms. For example, by forming a large number of screw holes in the front surface of the horizontal rail, the panel may be fixed to the horizontal rail with screws. Also, the crosspiece is not limited to a square cross section,
It may have an L-shaped or C-shaped cross section. Further, the leg of the work desk may be a simple plate or a bar.

Further, a locking claw may be formed on the panel as a locking portion, and the locking claw may be dropped into a slot formed in the main horizontal rail as an engaging portion to be engaged. Further, the attachment of the auxiliary horizontal rail to the partition frame and the column is not limited to screwing, and a claw provided on the auxiliary horizontal rail may be dropped into a hole provided in the partition frame and the column. Further, the support frame is generally provided at a rear portion of the top plate, but may be disposed at a side portion of the top plate in addition to or instead of the rear portion.
