Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a moving device for tables and desks.

Usually, tables and desks are used in a fixed state,
When tables and desks used in lecture halls, conference rooms, etc. are increased or decreased, or when these areas are used for other purposes, the tables and desks may be moved and rearranged. 0 Conventionally, in order to measure the mobility of tables in such cases, it is known that the legs of the leg supports are equipped with casters that can be freely oriented in one direction. Tables with casters do not need to be carried around when moving and can be pushed, so they are relatively large tables used in conference rooms and lecture halls.

Although it is an effective means for desks, it lacks stability when in use, and it easily moves when the body leans over or leans over, causing problems with the alignment.

Of course, tables with casters are usually equipped with a stopper to stop the rotation of the wheels in order to ensure stability during use, but the casters with stoppers that are currently in practical use, especially those used for tables. The small casters are not structurally strong, so they cannot be used on tables or desks.
It is not capable of sufficiently resisting external forces such as P\.

However, the casters used for this machine can be moved to some extent despite the fact that the mounting shaft is free to rotate and the wheels are stopped, which makes it difficult to maintain a stable fixed state. be.

The present invention was developed in view of the above-mentioned situation #'c11.The present invention was developed in view of the above-mentioned circumstances. The other leg support is provided with a wheel that is allowed to rotate, and a floor contacting member is provided at the leg end of the other leg support, and when in use, this floor contacting member (in some cases, this floor contacting member may be the leg end itself). )
A table, a desk, etc. is fixed with wheels that are placed in contact with the floor surface and the movement direction is specified, while the leg support provided with the above-mentioned floor contact member is equipped with casters that can be raised and lowered, and the table,
When moving the desk, the casters are lowered below the floor contact member, and the core casters and the wheels move the table 9. To provide a moving device that allows a desk to be moved freely.

One feature of this device, as mentioned above, is that the wheels on one of the leg supports are always on the ground, and the casters on the other leg support are attached so that they can be raised and lowered. A table that is raised and brought directly into contact with the leg end or with a floor contacting member provided at the leg end.

The movement of the table is restrained, and when the table is moved, the casters are lowered to touch the floor, and the casters and the wheels work together to free the table. that it is unnecessary,
When moving, it is possible to convert from a fixed state to a movable state by lowering a caster provided on one of the leg supports, that is, it has excellent operability.

Hereinafter, the above features and other features of the present invention will be explained based on an embodiment illustrating the present invention. 9-Example: Figure 1 is a front view of the table, Figure 2 is a left side view, Figures 3 and 4 are enlarged side views with some of the main parts cut out. It is.

The table 1 shown here is equipped with nine pairs of leg supports 3 and 4 on the lower surface of the horizontally long top plate 2 so as to face each other on the left and right sides, and a reinforcing horizontal support is installed midway between the heights of the left and right leg supports 3 and 4. The frame 5 is passed over the legs so that the legs are vertically erected, and the lower ends of each legs are provided with horizontal legs 6 and 7 made of metal pipes, which are arranged in parallel with each other in length in the front and back direction. At the front and rear ends of the horizontal support leg 7 on the right in the drawing, specific gravity bearings 8 are provided by bending steel plates into a U-shape, and wheels 10'fr are supported on the axles 9 passing therethrough so that they can rotate freely. Further, at the front and rear ends of the left horizontal support leg 6, a screw receiver rod 11 is vertically provided on the lower surface, and a floor contacting member 12 for adjusting the height is screwed onto the rod.

The axle bearing 8 provided on the right horizontal support leg 6 is oriented in the left-right direction of the table, so that both axles rotate only in the left-right direction.

On the other hand, the left screw receiver is the rod 11 and the floor contact member 12 is aligned with the right leg support leg 7 whose overall height increases due to the installation of the wheel 10, and also aligns the left leg support leg 6 with the unevenness of the floor surface. This is a member for adjusting the height of the table to eliminate the wobbling of the table.By twisting the flooring member 12, the screw receiver can be moved in and out of the male threaded rod screwed into the rod 1, and its height can be adjusted. This allows for adjustments to be made. Incidentally, reference numerals 13 and 14 in the drawings indicate covers attached to cover the wheel bearing 8 and screw receiver to cover the rod 1 and both ends of each horizontal support leg.

Therefore, the table 1 shown here is normally supported by the axle 10 and the floor member 12 of the horizontal support legs 6.7 provided at the lower ends of the left and right leg supports 3.4. In this embodiment, the device can be used in a stable state by adjusting the floor contact member provided on the left horizontal support leg 6 in response to unevenness of the floor surface. In this case, since the table l has a pair of front and rear wheels 1o provided on one leg support 7 in contact with the floor, it seems that the rotation of these wheels makes the table l unstable. Since the table is designed to rotate only in the left-right direction, it does not move in the front-back direction, so the right side of the table does not move back and forth arbitrarily when the table is in use. When it is moved left and right along the rotational direction, the floor contacting member provided on one of the leg supports 6 rubs against the floor surface, resulting in a brake effect and restraining the movement. The table supported by the wheels and the floor contacting member is kept in a stable state without moving arbitrarily during use, that is, during normal times.

In the figure, reference numeral 15 denotes casters provided on the left horizontal support leg 6 in order to smoothly roll and move the table in cooperation with the wheels 1o when the table is moved in a stable state.

The caster 15 shown here consists of two wheels 16, 16, an axle bearing 18 that receives the axle 17 of the wheels, and a freely rotatable shaft rod 19 extending perpendicularly from the axle bearing 8, and this shaft rod 19ii. - It is assembled so as to be engaged with the stopper device 21 that is inserted into the hollow interior of the horizontal support leg 6 by passing it from below through a through hole formed in the upper part of the left horizontal support leg 6.

The stopper device 21 is for capturing the shaft rod 19 passing vertically through the horizontal support leg through the above-mentioned through hole (to) and restraining its free vertical movement. It is composed of a coiled spring 24 that applies pressure.

As shown in FIGS. 3 and 85, the mounting base 22 has legs 5 hanging in parallel from two opposing sides of a rectangular metal plate to form a U-shape, and upwards from the other two opposing sides. The fixing piece is extended to form a substantially saddle shape, and a through hole 27t through which the shaft rod 19t is inserted is bored in the horizontal metal plate part so as to be biased toward one fixing side. The base of one of the fixing pieces is provided with an insertion hole 4 into which the protruding side provided at one end of the stopper juicer is inserted.

The stopper piece is formed by bending a metal plate into a U-shape, and has an integral operating piece bent at a nearly right angle at the end opposite to the above-mentioned protruding side. It can be assembled to the mounting base n by inserting it into the insertion hole 4 of the mounting base n. By this assembly, the shaft rod 19 of the caster is placed at a position corresponding to the through hole n of the base 4.
T-Through hole 31f: drilled. The coiled spring is compressed between the mounting base n and the stopper piece to be assembled, and always urges the free end side of this stopper piece upward, the end on the side of the tab operation piece (9). be incorporated to do so.

This stopper device 21 is inserted into the hollow interior from one open end of the horizontal support leg 6 with the mounting base n, stopper piece, and coiled spring assembled, and the through hole provided in the mounting base and the stopper piece. Connect n and 31 to the upper and lower through holes of the horizontal support leg (to)
In the figure, the wings are connected to the casters by making the operation piece (material) of the stopper piece n protrude upward through the window 32 formed on the upper surface of the horizontal support leg 6. This is a spring that constantly urges the shaft rod 19 of No. 15 upward, and the word is a seat plate that receives this spring.

The shaft rod 19 has a flange in the middle of its length to receive the spring 33t, and is designed to receive one end of the spring wound around the shaft below the flange. And this tsuba 35 and spring 3
3, the lower through-hole of the horizontal support leg has a larger diameter than the upper through-hole.

The seat plate receives the other end of the spring and also closes 20% of the large-diameter through hole, and a hole I for passing the shaft rod 19 is provided in the center. This seat plate incorporates the stopper device 121 inside the horizontal support leg as described above, and then inserts the shaft rod 19 into the valley through-hole 2 of the stopper device by drilling a through-hole.
7, 31, and after fitting the spring 33 to this shaft rod, the shaft rod is passed through the hole 36, placed on the lower surface of the horizontal support leg, and fixed with screws to fit the large diameter through hole 20. This screw fixing compresses the spring and urges the shaft rod 19 upward.

Although the shaft rod 19 shown here is not shown, it has a female threaded hole in the shaft center of the lower end, and the other wheel bearing 18 (this is a rotating shaft part 37 that rotates freely with respect to the main body). A male screw rod is provided extending from the shaft portion, and the male screw rod is screwed into the female screw hole of the shaft rod so that the shaft rod can be assembled into one body, and the shaft rod can be assembled via the rotating shaft portion. This allows for free rotation.

Now, with the caster 5 assembled in this way on one horizontal support leg 61C, the shaft rod 19 rises due to the biasing force of the spring, and the flange provided thereon comes into contact with the underside of the mounting base ρ, and when it reaches 9. , the wheels 16 are raised by ground-contacting members provided at both ends of the horizontal support leg 6 and are moved away from the floor surface. therefore,
Under normal conditions, these casters are suspended in the air, and as mentioned above, the table itself is supported by two wheels 1 installed on the horizontal support leg on the right side.
It is supported by the floor contacting member ratio of 0 and the left side.

When moving this table, the left side of the top plate 2 is lifted, the left floor contacting member 12 is lifted, and then the casters 1 are moved.
When the upper end of the shaft rod 19 of No. 5 is pushed down, it descends using the through hole J as a guide, and the caster wheel 16 comes out under the floor contact member 12. By the way, as a result of this push-down, the shaft rod 19 descends while compressing the spring a3, and as a result, it is biased in the direction of pressure rising when the push-down is released, but the stopper dispenser is always engaged with this shaft rod. Since it is aligned, it will stop at the depressed position, and the wheel +6 will be restrained in the protruding state.

That is, the shaft rod 19 of the caster is inserted into the through hole 2 of the horizontal support leg 6.
0 as a guide, but this shaft rod is also attached to the through hole 3 of the stopper dispenser of the stopper device 21.
1, and this stopper piece is constantly pushed upward by the force of the coiled spring, causing the edge of the through hole 31 to engage the circumferential surface of the shaft rod 31, so that movement in the upward direction is prevented. This is impossible unless this stopper piece 23 is released.

As a result, when pushed down, the nine-axis lever automatically stops at that position, and the wheel 16 of the kick star is restrained in a protruding state. This restraint is performed by pressing down the operating piece 30 of the stopper piece β, and the spring 3
B(D) The biased shaft lever automatically rises and pulls up the caster wheel 16. In short, the stopper dispenser here functions similarly to a swivel hook, and controls the vertical movement of the shaft rod 19. The device of the present invention is constructed as described above, and is supported by wheels 10 that can rotate only in left and right directions and a floor contact member during normal use, that is, when in use. Therefore, while the table can be kept in a stable state, when moving the table, the casters 15 provided on the side of the leg support on which the floor-contacting member is placed on the floor are lowered to float the floor-contacting member, and the table is supported by the casters and the wheels 10. Because of this, the table can be easily moved in the same way as a conventional table with casters or desks.Moreover, when moving the table, the wheel 10 provided on one of the leg supports has a fixed rotational direction, so it can be pushed easily. It has the advantage of being stable and allowing one person to easily move it to the desired location.

In order to carry out the present invention, when the casters are moved up and down by the stopper device 21 having the above structure, the table can be moved freely by pressing down the shaft 19, and the stopper device By pushing down on the soup dispenser, the shaft lever is released, and by pulling up the casters, the movement of the table can be restrained and fixed, making it extremely easy to handle.In addition, the stopper device here can be used with wheels or Needless to say, since the casters are not intended to stop the casters from rotating, their strength does not directly pose a problem when using the table.

By the way, in the above embodiment, the leg support 3. which supports the top plate 2.
4 is provided on each side on the left and right, and the horizontal support legs 6 and 7 are placed on the leg ends. Alternatively, a wheel 1o may be provided, and a floor-contacting member may be provided at the other front and rear leg ends. In this case, a frame equivalent to the horizontal support leg 6 is passed between the front and rear legs on the side on which the floor contacting member is provided, and the cough frame is equipped with casters 15, as in the case of the previous embodiment.

Further, although the above embodiment has been described with reference to the case where one caster 15 is provided, the case where a plurality of casters are provided is not excluded. In this case, it would be disadvantageous in terms of cost and the operability would be poor, so it cannot be said to be a preferred implementation method.

In any of the above methods, a floor contacting member is provided at the leg end of one of the leg supports, and in the above embodiment, a floor contacting member with a height adjustment function is provided. The floor contacting member may be a simple cap-shaped member that protects the floor, or in some cases may be the end of the 0 leg of the leg support, and the shape is not specified in particular. Any item that can support a table or desk is fine.
