Description

  The present invention is a handle member used when transporting a relatively heavy apparatus (about 200 kg to 400 kg) having a caster such as an OA device such as a multifunction machine. The present invention relates to a handle member that can be used as a stabilizing member (a movement preventing member and a tipping preventing member, which may be collectively referred to as “movement preventing member” hereinafter). The present invention also relates to an apparatus suitable for the handle member.

  As one of OA devices, a copying machine, a printer, a facsimile machine that forms a toner image, or a complex machine that combines two or more of these is widely used. In such a complex machine, an electrostatic latent image is usually formed on an image carrier such as a photoconductor in an exposure process, and a visible toner image is formed by developing the electrostatic latent image in a development process. In the transfer process, the visible toner image is transferred to a recording medium such as recording paper, or temporarily transferred to an intermediate transfer body such as an intermediate transfer belt, and then secondarily transferred from the intermediate transfer body to the recording medium. Thus, the toner image transferred onto the recording medium can be fixed on the recording medium.

  Many devices such as a multifunction machine having a volume of about 1 cubic meter, for example, often have a considerable weight. For this reason, in such a multi-function machine, a transport worker (hereinafter simply referred to as “worker”) is required during transport or movement (hereinafter collectively referred to as “transport”). In order to make it easier to hold the multifunction device, a protrusion to be used as a clue is provided at an appropriate position on the side surface, a recess is provided to make it easier to hold and grip the hand, and the multifunction device main body should be used only during transportation. A separate handle member that can be attached and detached is provided, or a handle that can be taken in and out of the main body of the multifunction device is provided. For example, Japanese Patent Laid-Open No. 2000-258969 (Patent Document 1) discloses a handle for solving such a problem.

  This handle is a carrying handle equipped on the device, and the handle is supported so as to be able to move in and out of the device side from the retracted position in the device body, and a handle protruding from the device body to the side is used. It is characterized in that when the force for maintaining the protruding state is released, the handle is retracted into the device body without applying external force to the handle.

  In this way, while taking advantage of the function of a haulable handle, it can be stored naturally inside the device except during use (during transport), so the cumbersome operation for storage, forgetting to store, storing It is possible to solve problems such as hooking a handle that is not protruding or tipping over with a protruding handle.

JP 2000-258969 A

  OA devices such as the above-described multifunction peripherals may be provided with casters so that they can be easily moved when transported to an installation location by an operator. When transporting to the installation location, the multifunction device can be easily moved by this caster.After transporting to the installation location, the multifunction device can be operated by locking the caster with the lock mechanism provided on the caster. It can be prevented from moving from the installation location. Such a multifunction machine generally has a rectangular shape on the bottom surface, and casters are attached near the corners of the multifunction machine so that the entire multifunction machine is supported by four casters. is there.

  By the way, the multi-function machine provided with such casters supports the multi-function machine only at the contact portion between the floor surface, which is the installation surface of the multi-function machine, and the casters, so that the friction is reduced. For this reason, there is a possibility that the multifunction machine slides and moves on the floor surface even though the caster is locked due to shaking caused by an earthquake or the like. At this time, if there are protrusions or the like on the floor surface, the caster hits the protrusions and the multifunction device falls over. In order to prevent such an inadvertent movement and overturn of the multifunction device, a movement preventing member separate from the multifunction device may be used. For example, the movement preventing member may be fastened using a screw hole provided on the floor surface, and the movement preventing member may be fastened to the multifunction peripheral, thereby preventing the multifunction peripheral from being accidentally moved and overturned.

  Thus, the movement preventing member (falling prevention member) is not necessary during transportation (rather, it hinders smooth transportation) and is necessary after installation. On the other hand, the handle member including the handle disclosed in Patent Document 1 is often required during transportation and is generally unnecessary after installation. As described above, when the movement preventing member and the handle member are formed as separate members from the multifunction machine, the necessary times are different from each other, and both are not required at the same time. In this respect, a member configured separately from the multifunction machine can be used as the movement preventing member and the handle member.

  However, Patent Document 1 does not consider the point that the handle member is also used as a movement preventing member. Note that the handle disclosed in Patent Document 1 needs to provide a space for storing the handle inside the device, which increases the size of the device. In addition, the handle disclosed in Patent Document 1 needs to be configured so as to be able to appear and retract, requiring a complicated structure, and increasing the cost.

  Therefore, the present invention is a handle member used when transporting a device such as an OA device, and can be used as a movement prevention member after installation, and an inexpensive handle member that also serves as a movement prevention member. The issue is to provide.

Furthermore, the length from the hole 101A and the hole 102A of the handle member 100 to the end of the handle member 100 (the lower surface of the flat plate 103) is as follows. The length from the lower surface of the image forming apparatus A to the end of the handle member 100 (the lower surface of the flat plate 103) when the shaft 121 is inserted into the hole 101A and the hole 102A is the height of the caster CA of the image forming apparatus A. Same or slightly longer than the height of the caster CA.

[Handling and mounting work of handle members]
An operation of attaching the handle member 100 according to the present embodiment having the above-described structure to the image forming apparatus A (as a handle member) and a carrying operation will be described.

  As described above with reference to FIG. 5, the flat plate 103 of the handle member 100 is parallel to (or inclined to) the housing side surface of the image forming apparatus A, and the flat plate 103 is hollow in the engagement hole 110. The cylinder 101 is inserted to a position where the locking portion 101B of the cylinder 101 engages with the notch 111 of the engagement hole 110. In this state, when the handle member 100 is pushed upward vertically, the locking portion 101B of the hollow cylinder 101 engages with the notch 111 of the engagement hole 110. At this time, the locking portion 101B is fitted to the notch 111 by slightly increasing the diameter of the notch 111 by making the system of the locking portion 101B and the diameter of the notch 111 of the engagement hole 110 slightly larger. Thus, the handle member 100 is fitted into the image forming apparatus A.

  In the region H (1), region H (2), region H (3), and region H (4) of the image forming apparatus A, the locking portion 101B is fitted into the notch 111 in the state shown in FIG. Then, the handle member 100 is attached to the image forming apparatus A. In such a state, the image forming apparatus A is surrounded by four workers, each holds the cover 102 with their hands, and lifts the image forming apparatus A upward (basic configuration called unit U (1)) Or the image forming apparatus A is moved to the side.

  The form in which the handle member 100 is attached to the image forming apparatus A is not limited to the fitting between the locking portion 101B and the notch 111. What is necessary is just to obtain the intensity | strength and connection force suitable for conveyance work, for example, you may screw together with a screw etc.

[Handling member mounting operation and movement prevention work]
An attachment operation and a movement prevention work as a movement prevention member of the handle member 100 according to the present embodiment having the above-described structure to the image forming apparatus A will be described.

  As shown in FIG. 6 described above, when the handle member 100 is attached to the image forming apparatus A, for example, when an impact is applied to the upper surface of the handle member 100 from above, the engagement portion 101B and the notch portion 111 are separated. The mating is released. When the handle member 100 is pushed down vertically in the reverse procedure to the above-described procedure, the handle member 100 and the image forming apparatus A are separated as shown in FIG. By this procedure, all the handle members 100 attached to the regions H (1), H (2), H (3), and H (4) are separated from the image forming apparatus A.

  The handle member 100 shown in FIG. 5 is rotated in the direction of the handle member 100 shown in FIG. By this rotation, the flat plate 103 of the handle member 100 becomes parallel to the floor surface, and the hole portion 101A and the hole portion 102A of the handle member 100 face the shaft 121. The handle member 100 is brought close to the image forming apparatus A so that the shaft 121 is inserted into the hole portion 101A and the hole portion 102A of the handle member 100 facing the shaft 121 of the recess 120. At this time, the length from the lower surface of the image forming apparatus A to the end of the handle member 100 (the lower surface of the flat plate 103) when the shaft 121 is inserted into the hole 101A and the hole 102A is the caster CA of the image forming apparatus A. If the height is the same as the height (hereinafter referred to as A), the shaft 121 is smoothly inserted into the hole 101A and the hole 102A of the handle member 100. When the length from the lower surface of the image forming apparatus A to the end of the handle member 100 (the lower surface of the flat plate 103) when the shaft 121 is inserted into the hole 101A and the hole 102A is slightly longer than the height of the caster CA ( Hereinafter, in the case of B), for example, the image forming apparatus A is slightly lifted. In the case of B, when the caster CA or the image forming apparatus A includes an adjuster mechanism, the adjuster mechanism is used to slightly lift the image forming apparatus A and the holes 101 </ b> A of the handle member 100. The shaft 121 may be inserted into the hole 102A, and then the image forming apparatus A may be lowered using an adjuster mechanism.

  As described above, when the handle member 100 is attached to the image dispute apparatus A as a movement preventing member, the flat plate 103 receives the weight of the image forming apparatus A. The magnitude of the force changes. For this reason, it is necessary for the flat plate 103 to receive the weight of the image forming apparatus A so that the four flat plates 103 can develop (static) frictional force that does not move the image forming apparatus A.

  In the case of B described above, since the caster CA is floating from the floor surface, the caster CA does not receive the weight of the image forming apparatus A, and the four plates 103 receive the total weight of the image forming apparatus A in a distributed manner. ing. On the other hand, in the case of A described above, since the caster CA does not float from the floor surface, the caster CA receives a part of the weight of the image forming apparatus A, and the four flat plates 103 disperse the total weight of the image forming apparatus A. It may not be received. For this reason, in the case of A, for example, it is necessary to select a material for the flat plate 103 such that the static friction coefficient between the flat plate 103 and the floor surface is higher than in the case of B. As described above, the shape of the handle member 100 (size of the flat plate 103) and the material of the handle member 100 (static friction coefficient between the flat plate 103 and the floor surface) are set so that sufficient (static) frictional force is expressed. The material of the flat plate 103 to be determined) and the weight of the image forming apparatus A received by the handle member 100 (the end of the handle member 100 from the lower surface of the image forming apparatus A when the shaft 121 is inserted into the hole 101A and the hole 102A). What is necessary is just to set suitably the length to the lower surface) of the flat plate 103, etc. In the case where the floor surface is carpeted or from the viewpoint of simply suppressing inadvertent movement of the image forming apparatus A, it may not be necessary to perform exact calculation based on (static) frictional force.

  In regions S (1), S (2), S (3), and S (4) of image forming apparatus A, shaft 121 is inserted into hole 101A and hole 102A in the state shown in FIG. Then, the handle member 100 is attached to the image forming apparatus A. In such a state, even if the image forming apparatus A is provided with the casters CA, the flat plate 103 is in contact with the floor surface, and the flat plate 103 receives the weight of the image forming apparatus A. It is possible to suppress the movement to the ready, and it is possible to suppress the inadvertent movement, so that it is possible to suppress the fall.

  The form in which the handle member 100 is attached to the image forming apparatus A is not limited to the form in which the shaft 121 is inserted into the hole 101A and the hole 102A. It is only necessary to prevent the image forming apparatus A from moving.

  As described above, according to the handle member according to the present embodiment, the operator engages the side surface of the image forming apparatus A during transportation and uses it as a handle. When the transporting operation is finished, the handle member that is locked to the side surface is removed, and attached to the vicinity of the lower surface of the image forming apparatus so that the casters of the image forming apparatus A are separated from the floor surface. For this reason, the handle member concerning this Embodiment is used as a handle at the time of conveyance, and can be used as a movement prevention member after completion | finish of conveyance in which a handle becomes unnecessary.

<Modification of the first embodiment>
Hereinafter, a handle member 130 according to a modification of the first embodiment will be described with reference to FIGS. 9 and 10. Detailed description of the same structure as that of the first embodiment will not be repeated here. The image forming apparatus to be attached has the same overall structure and the same housing structure, and the same mounting operation and carrying work as a handle member to the image forming apparatus.

[Structure of handle parts]
As shown in FIG. 9, the handle member 130 according to this modification is replaced with a screw 131 </ b> A on the outer peripheral surface welded to the flat plate 133 instead of the hollow cylinder 101 of the handle member 100 according to the first embodiment described above. A hollow cylinder 131 provided with Furthermore, the handle member 100 according to the first embodiment described above is provided with a hollow cylinder 132 provided with a screw 132B screwed to the screw 131A on the inner peripheral surface thereof.

  The hollow cylinder 131 includes a hole (not shown) corresponding to the hole 101A or the hole 102A. The hollow cylinder 132 includes a hole 132A corresponding to the hole 101A or the hole 102A. Although not shown in FIG. 9, it is also preferable to provide a cover (corresponding to the cover 102) on the outer periphery of the hollow cylinder 132. The handle member 130 is configured by welding a metal hollow cylinder 131 to a metal flat plate 133, for example. The area of the flat plate 133 is preferably large enough that the four flat plates 133 come into contact with the floor surface and the image forming apparatus A does not move (static).

  The material, thickness, and screw dimensions of the hollow cylinder 131 and the hollow cylinder 132 need to have rigidity that does not deform even when receiving the weight of the image forming apparatus A.

[Handling member mounting operation and movement prevention work]
An attachment operation and a movement preventing work as a movement preventing member of the handle member 130 according to this modification having the above-described structure to the image forming apparatus A will be described with reference to FIG.

  The handle member 130 is brought close to the image forming apparatus A so that the shaft 121 is inserted into the hole 132A of the handle member 130 facing the shaft 121 of the recess 120.

When the shaft 121 is inserted into the hole 132A, the length from the lower surface of the image forming apparatus A to the end of the handle member 100 (the lower surface of the flat plate 103) is made longer than the height of the caster CA of the image forming apparatus A. . In this case, since the caster CA floats from the floor surface, the caster CA does not receive the weight of the image forming apparatus A, and the four flat plates 133 receive the total weight of the image forming apparatus A in a distributed manner.

  In region S (1), region S (2), region S (3), and region S (4) of image forming apparatus A, shaft 121 is inserted into hole 132A in the state shown in FIG. The member 130 is attached to the image forming apparatus A. In such a state, even if the image forming apparatus A is provided with the caster CA, the flat plate 133 comes into contact with the floor surface, and a large (static) frictional force is expressed by the flat plate 133 receiving the total weight of the image forming apparatus A. Therefore, the image forming apparatus A can be prevented from moving inadvertently, and the inadvertent movement can be suppressed. Also in this modification, it is not necessary to perform a strict calculation based on the (static) frictional force from the viewpoint of simply suppressing the inadvertent movement of the image forming apparatus A when the floor surface is carpeted. In some cases.

  As described above, according to the handle member according to the present modification, as the handle member according to the first embodiment, the handle member is used as a handle at the time of transportation, and is used as a movement preventing member after the end of transportation when the handle becomes unnecessary. Can be used. Furthermore, the work in the case where the handle member according to this modification is attached to the image forming apparatus as a movement preventing member is facilitated. When the handle member according to this modification is attached to the image forming apparatus as a handle member, if a lock member or the like is provided so as not to rotate in any of the directions indicated by the arrows in FIG. The member 130 is more preferable because it does not rotate.
