Wooden pillar table

Scope of production

This arrangement relates to a height-adjustable table with an upper countertop and a lower base member, a height-adjustable stand positioned between the countertop and the base member, each having a vertical upright lower base attached to the base member, as another parallel mounted to the countertop legs can be displaced relative to.

Tables of this kind have been developed for workplaces where height adjustment of a countertop 10 or work area is appropriate in the work situation.

The term workplaces must be understood in a broad sense and includes, for example, desks to be used as sitting / standing tables where there may be a desire for height adjustment from, for example, 65 to 135 cm.

15

There may also be mounting places, welding tables and packing tables to be used by changing operators or to be used during work where height adjustment is needed.

The term countertop should be taken in a broad sense and thus may include actual countertops or racks designed to support items to be machined and / or assembled.

25 Prior art

Tables that can be adjusted in height consist of a number of mechanical parts, which are placed around the table, which makes mounting and other fabrication of the table difficult.

A table as described in Utility Model Application No. 9800051 is characterized by consisting of 30 parts and by being easy to manufacture. The height adjustment in this table is done by moving two columns relative to each other. The built-in constant force mechanism of the table causes a load on the worktop to be balanced so that the height adjustment takes place effortlessly and using minimal force both downwards and upwards. Since this table is only two-pillar, the vertical alignment path will be limited, which means that the table is not ideally suited for both small and large people.

The technical problem to be solved

The above-mentioned tables are cumbersome to produce, while limiting the vertical displacement of the worktop.

With the creation, it is desired to provide an improved type of the known height adjustable tables. The new table, as described in utility model application No. 9800051, must be easy to produce.

In addition, it is desired to provide an improved type of tables which can be displaced vertically over a greater distance so that the height of the countertop can be adapted to both small and large people.

The new technique

What is new about the production is that the table has 3 legs or columns that can be moved vertically relative to one another.

And that all mechanical parts are assembled in a unit around the main shaft (8).

The mechanical unit is located in the middle part (1 + 2). It consists of a mechanism for generating constant force and is connected to the main shaft (8) via a drum, so that a constant torque is created on the main shaft (8) with the need to equalize the gravity acting on the table top. The constant force generation mechanism may be a constant force spring or other constant force mechanism e.g. as described in utility model application No. 9800050.1 both ends of the main shaft (8) or near the ends a "slave leg" (6) is mounted. At the other end of the slave leg is a transmission element (7) mounted. On the main shaft (8), next to The slave leg (6) is attached at both ends to a transmission element (7a) .A chain (12) from the upper transmission element (7a) extends down around the lower transmission element (7) so that a rotation of the main shaft (8) will drive the transmission elements (7 + 7a) and the transmission means (12) around.

The slave legs (6) are located inside the inner legs (13).

A displaceable bearing (5a) is arranged in the inner legs (1a), which fits into the middle legs (1), so that the inner legs (13) can be easily moved up and down inside the middle legs (1).

Also, a displaceable bearing (5) is arranged in the intermediate legs (1) which fits into the outer legs (3) so that the intermediate legs (1) can be moved up and down in the outer legs (3).

Two tubular or rod-shaped elements (15 + 16) are attached to the transmission means (12). These extend along the transmission means. The upper end of element 15 is attached to one strand of the transmission member (12) near the upper transmission element (7a), while the other end of element 15 is attached to the foot of the table (4). The lower end of element 16 is attached to the opposite strand of the transmission means near the lower transmission element (7), while the upper end of element 16 is attached to the inner leg (13) 5 or alternatively to the top leg (14).

A rotation of the main shaft (8) will cause the transmission elements (7 + 7a) to rotate, whereby the transmission means (12) will move down one side and up the other. Turning the point on the transmission member (12) to which element 15 is secured down, element 10 will push the foot (4) and outer leg (3) down, and element 16 will push the inner leg (13) and top leg (14) up.

The result is that the middle leg (1), slave leg (6) and box (2) with lid (9), shaft (8) and constant force mechanism are lifted from the floor at the speed v.

The inner leg (13), top cheek (14) and table top () lift relative to the middle leg (l) at the same speed v.

The table top () finally rises from the floor at the speed of 2v.

Technical effect 20 A height-adjustable table having three columns is provided at the table according to the invention, whereby the vertical displacement is so large that the height of the table top can be adapted to both large and small people. The table's built-in constant force mechanism causes a load on the worktop to be balanced so that the height adjustment is effortless. At the same time, according to the manufacture, a height adjustable table is provided, in which all mechanical parts are assembled in a unit around the main shaft. The parts of the table can thus be assembled very quickly without first having to adapt a series of mechanical parts around the table to one another.

When adjusting the height, the inner leg will move out of the middle leg at the same speed as the middle leg moves out of the outer leg, so 30
