The present invention relates to a scaffold that is used as an aid to a table or a lecture object placed on a stage of a cathedral, a church or a ceremonial hall, or other various meeting places, and more particularly relates to a scaffold for a river object that can be adjusted in height.

There are various kinds of river objects that have been placed on the stages of cathedrals, churches, ceremonial halls, and other meeting places, and are used as a table.As an example, the table is made of crystal material used for river objects. It consists of a base board material and a top board material substantially, and many pillar bodies between these base board materials and a top board material.

In more detail, the steel object places several pillars having a predetermined length in advance on the base plate, and the upper plate is mounted on the pillars to constitute the desired steel object.

In this way, the targets are constructed with a certain height so that they can be used in common, considering the height of users (teachers), for example, maximum and minimum heights. The users of the minimum height, but the user of the minimum height is additionally provided with a separate rise plate that can adjust their height to match the height of the river target.

By the way, these upholstery boards are manufactured in the shape of a rectangular parallelepiped, and these upholstery boards are manufactured at a predetermined height. There were many problems, such as preparation.

The present invention has been made in consideration of the above circumstances, the purpose of which can be used to freely adjust the height of the scaffold, the height of the height adjustable scaffolding that can be used universally and publicly by users of various heights To provide.

The object of the present invention is achieved by providing a platform for a steel object used as a table by placing it on the stage of a church, a church, a wedding hall, or other meeting places, and the platform is divided into upper and lower parts. Including an upper body and a lower body coupled to each other in combination with each other, the elevating operation means for raising and lowering the upper body interposed between the upper and lower bodies, and a driving means for operating the lifting operation means, By operating the lifting operation means by means to raise and lower the upper body on the lower body to be able to adjust the height of the scaffold appropriately for various heights.

Next, an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is to provide a footrest for the foot which is placed on the pedestal of a church, a church or a ceremonial hall, and other various meeting places and additionally provided to a table or a lecture object.

The present invention is additionally provided in the vicinity of the steel object as a footrest for the height adjustment of the instructor's height, in FIG. It is arranged to be used.

2a and 2b is a cross-sectional view showing the configuration and the working relationship of the present invention scaffold 20. The footrest 20 of the present invention consists of an upper body 22 and a lower body 24 which are formed in a substantially hollow enclosure shape and are separated from each other up and down to be combined with each other.

The lifting and lowering operation means 30 for raising and lowering the upper body 22 by a pair of operating tables 32 and 34 which are folded by scissors between the upper and lower bodies 22 and 24 configured as described above is provided. Is installed.

In more detail with respect to the lifting operation means 30, the lifting operation means 30 is a fixed end that is rotatably fixed to one end of each of the inner wall of the ceiling or bottom of the upper and lower bodies (22, 24) (32a, 34a) and the other end of the free end (32b, 34b) is installed in sliding contact with a pair of operating tables (32, 34) that are folded by scissors using a rotating shaft 33 is installed in the center, Each end of the operating tables 32 and 34 is connected between the operating tables 32 and 34 and the other end is connected to a receiving table 35a which receives a driving force applied from the driving means 36 to be described later. It consists of a power transmission element 35 having a pair of connecting rods 35b and 35c.

The drive means 36 shows one example thereof. The handle 36a, which is manually operated, and the power transmission element 35 are coupled to the axial length direction of the handle 36a, and the handle 36a is forward and backward. It consists of a lead screw (36b) to achieve a forward and backward movement for the transmission of the driving force of the power transmission element 35 by driving to.

In addition, the driving means 36 includes an actuator (not shown) driven by a step motor or a fluid pressure, and the power transmission element 35 is coupled to the axial length direction of the actuator and drives the actuator in forward and reverse directions. It may be composed of a lead screw to achieve a forward and backward movement for transmitting the driving force of the power transmission element 35.

Then, when describing the operating state of the footrest 20 is adjustable height design of the present invention, Figure 2a shows a state having a height of the lowest position. In this state, when the handle 36a of the driving means 36 is rotated in one direction, the receiving stand 35a located on the left side of the lead screw 36b is pushed to the right to connect the driving force of the driving means 36 to the connecting rods. It is transmitted through the (35b, 35c) to the operating platform (32, 34) to open the retracted operating platform (32, 34), and at the same time the free end (32b, 34b) of the operating platform (32, 34) The upper and lower bodies 22 are pushed upwards by sliding up and down in the open state while sliding on the inner walls of the lower bodies 22 and 24 to adjust the desired height. 2b shows the height of the highest position.

The present invention is to be able to freely adjust the height of the footrest, by adjusting the height appropriately for users of various heights can be used in common.

As described above, an embodiment of the present invention has been described, but the present invention is not limited thereto and may be changed within the scope of the claims.
