DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woodworking work table mainly used for working long objects such as pillars.

[0002]

2. Description of the Related Art Wood is processed in various forms before it is used on site, and a suitable work table is required for any processing. In particular, long materials such as pillars
It may be difficult to handle due to the weight and size, and the suitability or unsuitability of the work table greatly affects the workability. For example, when processing wood by sending it to a universal woodworking machine, a workbench with a feed roller is convenient, but on the other hand, when the worker himself performs mortise, square hole carving, grinding powder, etc. A workbench without a feed roller is more convenient.

Conventionally, a work table provided with a feed roller and a work table not provided with a feed roller have been prepared for each of the above-mentioned works, and a work table suitable for the work has been selected and used. Worktables without feed rollers are often manufactured by workers themselves using appropriate waste materials, and worktables with feed rollers are sometimes commercially available as feed rollers. On the other hand, the roller unit was nailed to the upper part of the work table made by the user, or a commercially available height-adjustable product shown in FIG. 4 was used.

[0004]

However, most of the conventional worktables are used with limited installation positions, and are difficult to relocate or store due to their size and configuration.
It was not suitable for use in other workplaces and sites, or for effective use of space in narrow workplaces. In addition, since the uses are limited in terms of configuration, it is difficult to reduce the number of tools held in the work place by using the work table for a plurality of uses.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a woodworking worktable in which space can be effectively used by diversifying uses and making the space compact, and where use is not limited. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The woodworking workbench according to the present invention
A roller 3, which projects from the surface of the top plate 2 and rotates, is detachably attached to a worktable main body 4, which is formed in a so-called horse form in which the pair of legs 1, 1 is appropriately opened and raised. It is provided.

[0008] The leg 1 of the worktable main body 4 has two struts 5,
5, a top plate 2 and a step bar 6 are combined to form a rectangular frame, and a leg 7 is slidably fixed to each support 5 via a leg length adjusting portion 8. The leg 1 is provided with braces 9, 9, 9, 9 at the four joints where the above components are combined to prevent rattling of the workbench body 4 and enhance safety. Is given. Top plate 2 for each leg 1
Are formed wider than the struts 5 and the stairs 6, so that the top plate 2, the struts 5, 5 and the stairs 6
Are almost flush with each other, but in the opposite direction, only the top plate 2 projects relatively largely with respect to the side surfaces of the columns 5, 5 and the crosspiece 6. The top plate 2 is attached to the support column 5 with a slight inclination so that the work table body 4 is substantially horizontal with the legs opened.

The leg length adjusting portion 8 adjusts the length of the leg while being fixed to the lower end of the side surface of each column 5 with a rivet 10. The leg length adjusting portion 8 is provided at the upper and lower ends of a frame 11 surrounding the side surface of the column 5 in a U-shape, for example, as shown in FIG. 3, so that the leg 7 can slide along the longitudinal direction of the column 5. , Guide pieces 12, 1 with sliding holes (not shown)
2 are further provided, and a locking metal fitting 13 formed by stacking two pieces of plates each having a locking hole (not shown) is lifted up by a spring 14 with one end in the longitudinal direction hooked on the inner surface of the frame 11. It is provided by biasing in the direction.

The leg 7 slides along the sliding hole and the biting hole, and the sliding is prohibited in a state where the biting metal 13 is directed obliquely upward. It is slidable in a state facing diagonally downward. The leg length adjusting portion 8 is provided with a protective frame 15 that covers the upper part of the leg length adjusting portion 8 so that the engaging metal fitting 13 does not fall down when it is not intended. The locking metal fitting 13 may be composed of one or three or more plate pieces.
The stacking of a plurality of plate pieces is superior in the biting force, and is appropriately set in consideration of the biting force and the total weight of the worktable main body 4 suitable for the external appearance and the application. As described above, if the legs 1 are configured to be able to expand and contract independently of each of the four legs, the horizontal state of the top plate 2 can be easily maintained even when there are steps or the like in the installation location.

A pair of legs 1, 1 constructed as described above
Are openably and closably connected via a pair of reinforcing plates in which two reinforcing plates 16, 16 are pivotably connected. A joint 17 and a bearing 18 are provided on the reinforcing plate 16.
A screw hole (not shown) for fixing to the end surface of the top plate 2 and the upper end of the column 5 with a screw 19 is provided.
A shaft hole (not shown) for inserting a pin 20 serving as an opening / closing shaft of the above is formed. The reinforcing plate 16
Is formed by bending the joint 17 and the bearing 18 so that the concave sides 21 of the bearing 18 are slidably contacted with each other, thereby forming the joint between the reinforcing plates 16 and 16. 17, 17 are configured to swing on the same circular orbit. Above the bearing 18, contact portions 22 for limiting the swing of the reinforcing plate pair are provided, and a semicircular cutout 23 is formed in a part of the contact portion 22.

Further, bearing pieces (not shown) projecting opposite to each other are provided at both ends of the step bars 6 and 6 of the both legs 1 and 1, and both ends of the detent 25 are pivotally supported. The detent 25 is configured to bend and stretch with the opening and closing of the legs 1, 1. For example, after forming the cross section of one arm 26 into a hook shape and forming the other arm 27 into a flat plate shape, Hook-shaped section arm 26
The flat arm 27 is pivotally connected to the recess at one end so as to be accommodated in the recess, and the swing is restricted when the detent 25 is extended. That is, the detents 25 are bent upward and convex when the legs 1, 1 are closed,
When the legs 1 and 1 are opened and erected, they are in a straight line, and the legs 1 and 1 are prevented from closing each other.

The roller 3 of this embodiment has a roller bearing (not shown) fixed to both ends inside a roller body 28, and a shaft 29 is inserted through a rotary hole of the roller bearing. The width of the roller body 28 is set slightly shorter than the length of the top plate 2, and the length of the shaft 29 is set slightly longer than the length of the top plate 2. Further, in order to prevent the roller body 3 from falling off from the shaft 29, a through hole (not shown) penetrating both ends of the shaft 29 is formed, and the snap pin 3 is formed.
0 is inserted.

The surface of the top plate 2 in this embodiment is
An anti-slip material 31 such as a rubber plate having irregularities is stuck thereon, and a non-slip supporting member 32 is also fixed to the lower end of each leg 7 so that it can swing in an indeterminate direction. Therefore, when the wood is placed on the worktable and processed, the wood is prevented from slipping on the top plate 2 and the worktable body 4 is prevented from wobbling, so that the work can be performed safely and accurately. it can.

In this embodiment, the aluminum alloy is mainly used for the leg 1 and the like. However, the leg length adjusting portion 8 and the leg rod 7 inserted therethrough are located below the leg 1. The member is made of iron having a relatively large specific gravity and excellent strength. By using iron, in addition to the weight of the workbench body 4 becoming appropriately heavy, the center of gravity is also lowered, and the effect of increasing the stability of the workbench body 4 is added. In addition, a configuration made of stainless steel, wood having appropriate rigidity, synthetic resin, or the like is also possible. In particular, stainless steel, synthetic resin, and the like have high corrosion resistance.

The total weight of the worktable body 4 according to the present invention is 5 to 5 in order to achieve a good balance between good stability of the worktable body 4 when the wood is fed by the rollers 3 and ease of carrying. Approximately 10 kg is desirable, and as it deviates from the range, slip and fall with the floor surface increase, or
There is a problem that it is difficult to carry.

The woodworking workbench according to the present invention is constructed as described above. When the workbench main body 4 is erected in the most open state, the abutment portions 22 are provided at each pair of reinforcing plates at both ends of the top plate 2. They join. At this time, the semicircular cutouts 23, 23 formed in the abutting portions 22, 22 are aligned to form a circular bearing 33 capable of securely holding the shaft 29 of the roller 3. By holding the shaft 29 of the roller 3 with the bearing 33, the side surface of the roller 3 protrudes above the gap created between the top plates 2 and 2, and the long material is easily fed by the rotation of the roller 3. Can be. When the roller 3 is mounted in this manner, it can be used not only for transporting wood but also as an aid for transporting luggage at a luggage delivery place or the like.

Conversely, when the two legs 1 and 1 are closed, the contact portions 22 of the reinforcing plate pair are separated from each other, so that the bearing 33 is closed.
Are separated, forming a gap 34 above which the shaft 29 of the roller 3 can pass,
The roller 3 can be attached to and detached from the worktable main body 4. The mounting and dismounting method of the roller 3 is not limited to the above-described method. For example, a U-shaped bearing is provided in place of the bearing 33 so that the roller 3 is rotatably mounted at the center of the top plates 2 and 2. The roller 3 may be configured to be detachable regardless of the opening and closing of the legs 1, 1. At that time, it is desirable to additionally provide a lock mechanism for closing the entrance of the bearing in order to prevent the roller from deviating from the U-shaped bearing during the feeding operation of the wood.

[0019]

As described above, the woodworking workbench according to the present invention can be used not only for the work of securely holding the wood but also for the work of feeding the wood only by installing the rollers. In addition, since it has a compact and simple structure that can be opened and closed in two steps, it can be easily relocated to other places and can be used as a scaffold at a construction work site or the like. The woodworking workbench according to the present invention has a remarkable practical effect in effective use of space in a work place and improvement in work efficiency due to these various uses.
