JPH09236960A - Tipping prevention device for image forming device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the tipping of an image forming device during its transportation or after its installation by providing a means for holding a caster in a projecting position when the caster is in a projecting position and an external force in the directions other than its retracting direction is applied. SOLUTION: The caster 1 is attached to the front end of a bracket 2 as a support member, and a frame member 3, made of a pipe, which stores the bracket 2 is provided in the image forming device B. The bracket 2 is energized to the outside of the image forming device B by a spring 4, and is attached freely retractably to the pipe 3. When the image forming device B is moved, the image forming device B is tipping in the direction where the bracket 2 projects, the bracket 2 is not entered into the pipe 3 since the upper face of the bracket 2 and the pipe 3 are fixed in position by frictional force. As a result, the image forming device B is prevented from being tilted further around the caster 1 provided in the bracket 2, and, thus, prevented from tipping.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention device for an image forming apparatus such as a copying machine.

[0002]

2. Description of the Related Art In the case where an image forming apparatus such as a copying machine is liable to fall in a certain direction and is dangerous, for example, Sekisekihei 4-11225.
As shown in No. 4, there is a method in which an adjuster is arranged under the image forming apparatus and the adjuster is extended and grounded on the floor when the image forming apparatus is installed.

As another fall prevention means, there is also a method in which a foot is separately prepared and attached to the outside of the device.

[0004]

However, in the former method using the adjuster, since the adjuster is grounded within the installation area of the image forming apparatus, the fulcrum cannot be located outside the image forming apparatus. It is not possible to increase the safety of the fall afterward, and if you forget to extend the adjuster to ground it, it will not help to prevent the fall.

Further, the latter method using a foot has a drawback that it takes time to attach and detach the foot, or the foot is lost because it is a separate body from the image forming apparatus.

Furthermore, the fall prevention means of both does not function at all for preventing fall during transportation of the device.

Therefore, the present invention provides a fall prevention device for an image forming apparatus such as a copying machine, which prevents the image forming apparatus from falling during transportation or after installation.

[0008]

SUMMARY OF THE INVENTION The present invention is a fall prevention device for an image forming apparatus, wherein the caster is provided so as to be retractable to the outside of the main body of the image forming apparatus and biased in the protruding direction, and the caster is It is characterized in that a means for holding the caster at the protruding position is provided when an external force in a direction other than the retracting direction is applied at the protruding position.

As a means for holding the caster at the protruding position, a support member for the caster is provided slidably with respect to the frame member of the image forming apparatus main body, and a frictional resistance portion is formed at the sliding portion of both members.

Further, the support member of the caster is inserted inside or outside the frame member of the main body of the image forming apparatus, and an external force in a direction other than the protruding / retracting direction of the caster is applied to the upper surface of the support member of the caster where the end of the frame member is located. It can also be configured such that the ends of the frame members can engage when applied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a conceptual view of a fall prevention device of the present invention provided in an image forming apparatus. A fall prevention device A having casters 1 is arranged so that it can be stored in the bottom area of the image forming device B. It is set up.

FIG. 2 is a perspective view of the fall prevention device of the present invention.
The caster 1 is provided at the tip of a bracket 2 which is a supporting member, and the image forming apparatus B is provided with a frame member 3 made of a pipe for housing the bracket 2. The bracket 2 is biased to the outside of the image forming apparatus B by a spring 4, and is attached to the pipe 3 so as to be retractable.

The upper surface 5 of the bracket 2 and the pipe 3 in contact therewith are made of a material having a large coefficient of friction, or a material having a large coefficient of friction is attached.

Next, the operation of the fall prevention device A of the present invention will be described.

FIG. 3 is an explanatory view of the inclination prevention of the image forming apparatus by the fall prevention apparatus of the present invention. When the image forming apparatus B is moved, the image forming apparatus B tries to fall down in the protruding direction of the bracket 2 and is shown in FIG. When in the state shown, the bracket 2
The upper surface 5 and the pipe 3 are fixed by frictional force, so that they are not housed in the pipe 3, and as a result, the bracket 2
Forming device B with the caster 1 provided in the center as a fulcrum
Is supported so as not to tilt any more, and thus the image forming apparatus B can be prevented from falling.

Next, the case where the image forming apparatus B is installed with the direction in which the casters 1 are extended as a wall will be described. FIG. 4 is an explanatory view of the accommodation of the fall prevention device of the present invention in the image forming apparatus. Then, by pressing the image forming apparatus B directly toward the juxtaposition, the fall prevention apparatus A is housed in the pipe 3 of the image forming apparatus B as shown in FIG. 4, and the installation area is not increased.

FIGS. 5 and 6 are explanatory views of another embodiment of the present invention, in which a notch 6 is formed in the upper surface 5 of the bracket 2 so that when the image forming apparatus B tilts, The formed locking piece 7 falls into the notch 6 on the upper surface 5 of the bracket 2 to fix the expansion and contraction of the caster 1.

FIG. 7 is a sectional view showing another embodiment of the present invention. When the pipe 3 is housed in the bracket 3 and the hole 8 is formed in the bracket 3, the image forming apparatus B is tilted. , The tip of the pipe 3 falls into the hole 8 of the bracket 3,
Caster 1 will not move.

[0019]

【The invention's effect】

(1) In addition to providing a caster that can expand and contract outside the equipment in a direction where there is a risk of falling, and when the image forming apparatus tilts in one direction of the caster, the stopper that fixes the expansion and contraction of the caster operates, so that the image forming apparatus There is no risk of falling during transportation.

(2) When the image forming apparatus is installed, if the direction in which it tends to fall is in the open space, the casters extend outside the device, so it is possible to prevent the fall.

Further, when the image forming apparatus is installed on a wall or the like where there is no risk of falling, the fall prevention device is housed in the image forming apparatus, so that the ground area of the image forming apparatus does not increase.

(3) Since the fall prevention device is always provided in the equipment, there is no need to attach or remove it, and it does not get lost.
