Description

  The present invention relates to an image forming apparatus such as a copying machine, a facsimile machine, a printer, a scanner, or a multifunction machine having both functions, and in particular, a grip mounted to lift such an image forming apparatus for transportation and movement. It is related with improvement of a member (grip means).

  Conventionally, an image forming apparatus such as a printing apparatus, an image communication apparatus, and a copying machine is a relatively heavy device, and thus it is difficult to carry it while climbing stairs. On the other hand, since the office that delivers the image forming apparatus is not always equipped with an elevator, there is a need for the transporter to carry the stairs with the image forming apparatus by hand. For this reason, there are devices of this type in which a transport lever (gripping member) is attached to the device body.

  As such a transport lever, there is one provided so as to be able to be pulled out in the horizontal direction of the image forming apparatus (see, for example, Patent Documents 1 and 2). As shown in FIG. 2 of Patent Document 1 and FIG. 7 of Patent Document 2, the transport lever is housed inside the device when not transported, and is used by being pulled out of the device when transported. In order to prevent the transport lever from returning to the inside of the device during transport, the transport lever is provided with a lock mechanism. By this action of the locking mechanism, the transport lever is maintained in a state of protruding to the outside of the device. When the transport operation is completed, the lock mechanism is released and the transport lever is housed inside the device by the elastic force of the coil spring.

  However, when the transport lever is slid in the horizontal direction so as to be housed inside the device or taken out of the device, the image forming apparatus has a front opening / closing cover and a paper feed cassette stage. , It must be placed in an unobtrusive position. Therefore, there has been a problem that the mounting position of the transport lever is greatly restricted. In particular, when a thick transport lever is provided at a position suitable for transport under the above-mentioned restrictions, a space for storing the thick transport lever is required, and the entire image forming apparatus must be increased in size. There arises a problem that it is contrary to the request for conversion.

  Therefore, it is proposed that the transport lever is provided so as to be rotatable in the vertical direction of the image forming apparatus, and the storage space for the transport lever is formed near the side surface of the apparatus to reduce the storage space. (For example, refer to Patent Document 1). As shown in FIG. 7 of Patent Document 1, the transport lever is housed inside the device when not transported, and is used by being pulled out of the device by rotating in the vertical direction during transport. When the carrying work is finished, the carrying lever is released and dropped by its own weight and stored inside the equipment.

  However, in the case of a configuration in which the transport lever is rotated in the vertical direction to be housed inside the device or taken out of the device, one end of the transport lever is gripped and rotated in the vertical direction during transport. Pull out to the outside of the device and continue to grip and use one end of the transport lever in a horizontal state. If you stop gripping one end of the transport lever during transport, the transport lever will be stored inside the device by its own weight. The problem of being done occurs.

Therefore, in Patent Document 3, when the transport lever is rotated to a horizontal state, a lock member that is biased downward and movable in the vertical direction is fitted into a fitting groove provided on the upper surface of the transport lever. It has been proposed to prevent the transport lever from being housed inside the device due to its own weight by restricting (locking) the rotation of the transport lever (see Patent Document 3). In the prior art proposed in Patent Document 3, a slide-type unlocking part is separately provided inside the transporting lever so that the transporting lever is housed inside the device after transporting, and this unlocking part is placed horizontally on the lock member side. By moving, the lock member is pushed upward to release the fitting with the fitting groove.
Japanese Patent Laid-Open No. 2000-258969 (FIGS. 2, 3 and 7) Japanese Unexamined Patent Publication No. 2004-240444 (FIGS. 3 and 7) JP 2004-262202 A (FIGS. 2 and 3)

  However, in the prior art proposed in this Patent Document 3, there is a problem that the cost is increased because the locking mechanism and the unlocking mechanism of the transport lever are configured using a large number of parts. In addition, a certain amount of force is required for the operation of the unlocking portion, and there is a problem that the operability of the transport lever is poor.

  The present invention has been made in view of the above-described problems, and realizes a lock mechanism and a lock release mechanism of a rotating gripping member with a simple configuration, and sets, stores and transports the gripping member to a use state. The purpose is to improve the operability at the time.

  In order to achieve the above object, the present invention provides a gripping device having a gripping member that is rotated from a state of being housed in an apparatus main body and pulled out in a horizontally protruding state, and is rotated in a direction in which the gripping member protrudes. By doing so, the locking means for maintaining the gripping member in a state of projecting horizontally is automatically set, while the lock is released when the gripping member is rotated in the storing direction.

  The grip device of the present invention realizes the lock mechanism and the unlock mechanism of the rotating gripping member with a simple configuration using interference, engagement, friction, etc., and specifically, as follows. It is composed.

  That is, the grip device of the present invention is provided in an apparatus main body, and includes an enclosure-shaped storage unit that rotatably supports and stores the gripping member, and the gripping unit that is provided through one wall of the storage unit.

And keep it level. When the gripping member is stored, the locking means is released when it is rotated. Thereby, the operativity at the time of the setting to the use state of a holding member, accommodation, and conveyance can be improved. In addition, the gripping member is housed in a portion surrounded by a rectangular shape in which the bent plate is fixed to the folded portion of the side plate of the main body frame, and the gripping member is supported by the surrounding wall. Thus, it is possible to provide a grip device that can obtain sufficient strength for transporting the device without reducing the strength of the gripper.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing main components of an image forming apparatus provided with a handle device of the present invention.

  This image forming apparatus is a so-called tandem type color copier. A sheet feeding cassette 2 capable of stacking and storing a large number of sheets is disposed at the lower part of the apparatus main body 1, and a laser exposure apparatus (LSU unit) 3 is disposed above the sheet feeding cassette 2. Is disposed, and an endless intermediate transfer belt 4 is disposed thereon. In addition, first to fourth image forming units 5 to 8 for primarily transferring image data written by the exposure device 3 onto the intermediate transfer belt 4 as toner images corresponding to the respective colors Y, M, C, and K are intermediate. Arranged along the transfer belt 4. A conveyance path 9 is formed extending in the vertical direction near one side wall of the apparatus main body 1. When the image forming operation is started, the paper in the paper feed cassette 2 is transported along the transport path 9. In this process, the toner image primarily transferred onto the intermediate transfer belt 4 by each of the image forming units 5 to 8 is secondarily transferred onto the sheet by the secondary transfer roller 10, and then heated and fixed by the fixing device 11, and then the upper portion of the apparatus. To discharge. Note that a new paper feed cassette can be added as an option below the apparatus main body 1.

  Since this image forming apparatus is very heavy, during transportation, the two transporters cooperate to carry the apparatus body 1 one side at a time, and in particular, the side on which the conveyance path 9 is formed ( Since the main body weight is heavier than the opposite side (the right side of the drawing in FIG. 1), the grip device having a rotating gripping member for reducing the burden on the carrier having that side is provided on the left side in FIG. Provided. The transporter having the opposite side holds the apparatus main body by inserting his / her hand into recesses (not shown) provided at two locations on the main body exterior.

  Hereinafter, some specific embodiments of the grip device will be described.

  First, a first embodiment of the handle device of the present invention will be described. FIG. 2 is a perspective view showing the internal structure of the image forming apparatus including the handle device according to the first embodiment, and FIG. 3 is a view showing the periphery of the front holding member of the handle device according to the first embodiment. FIG. 4 is a longitudinal sectional view showing a storage state (a) of the gripping member of the handle device according to the first embodiment and a state (b) in which the gripping member is rotated to the horizontal position and protruded (b), FIG. 5 is a cross-sectional view showing a state in which the gripping member of the handle device according to the first embodiment is rotated to the horizontal position and protruded, and FIG. 6 is a gripping member of the handle device according to the first embodiment. FIG. 7 is a longitudinal sectional view of an essential part for explaining the operation of the locking means for maintaining the handle in a horizontally protruding state, and FIG. 7 is a perspective view of the gripping member of the handle device according to the first embodiment.

  As shown in FIG. 2, the image forming apparatus includes a frame 12 and an exterior portion (not shown) made of, for example, resin that covers the outside of the frame 12, and the frame 12 is erected on the front and back of the base member 13. The front side plate 14 and the rear side plate 15 are provided, and a plurality of stays 16 (only one is shown in FIG. 2) are provided between the side plates 14 and 15. Further, as shown in FIG. 2, the front side plate 14 is provided with an opening 17, and the image forming units 5 to 8 (see FIG. Mounting members 18 to 21 for mounting 1) are attached.

  The front side plate 14 has a folded portion 14a that is folded at a right angle to the front side at the left end portion. An encircling storage portion 22 that rotatably supports and stores the gripping member 23 is provided below the folded portion 14a. As shown in FIG. 3, the storage portion 22 is a two-stage L-shaped bent plate that is attached across the folded portion 14a, the back surface of the folded portion 14a, and the outer surface of the side plate 14 perpendicular to the folded portion 14a. It is comprised in the area | region enclosed with 24. The lower end of the bending plate 24 is in contact with the upper surface of the base member 13 as shown in FIG. As shown in FIGS. 3 and 5, the upper end portion of the bent plate 24 is cut out in an L shape with a predetermined height, including a portion that becomes the back wall of the storage portion 22. As shown in FIG. 4B, the height position of the upper side portion 24a of the notched bending plate 24 is set to a height that is flush with the outer surface of the bottom wall of the holding member 23 in the horizontal state. .

  A vertically long rectangular opening 25 is formed in the portion of the folded portion 14a where the storage portion 22 is formed. Since the opening 25 is a vertically long rectangle that matches the longitudinal dimension of the gripping member 23, the strength of the side plate 14 against twisting of the apparatus main body 1 may be reduced. In the present invention, the strength of the side plate 14 against twisting can be suppressed by fixing the bending member 24 to the side plate 14 provided with the opening 25 to create a surrounding configuration. The opening 25 is provided by punching the folded portion 14a. At this time, the vertical edge on one side of the opening 25 is left with a length slightly shorter than the opening width, and this is perpendicular to the inner direction of the storage portion 22. As shown in FIG. 5, a position restricting piece 26 that restricts the horizontal position of the gripping member 23 housed inside the housing portion 22 is formed. At the same time, the position restricting piece 26 plays a role of suppressing the strength reduction of the side plate 14 due to the opening 25 in combination with the configuration of the enclosure shape of the storage portion 22.

  As shown in FIG. 7, the gripping member 23 is a bar-shaped member that is manufactured by bending a sheet metal into a U-shape. A fulcrum hole 27 is provided at one end side in the longitudinal direction of both side walls of the gripping member 23 so as to penetrate the opposing position, and as shown in FIGS. 4 (a) and 4 (b), In the upper part, the grip member 23 is rotatably supported by a fulcrum pin 28 inserted through the fulcrum hole 27 and stored.

  Further, the upper surface of both side walls of the gripping member 23 is engaged with the upper side portion 25a of the opening 25 of the folded portion 14a in a substantially horizontal state near the fulcrum hole 27 in the longitudinal direction and near the other end. A groove 29 to be cut is formed. A curved interference portion 29a that interferes with the upper side portion 25a of the opening 25 of the folded portion 14a is formed on one end surface of the groove 29 at the engagement position while the gripping member 23 is rotating.

  Further, a protruding piece is integrally formed at one end portion of the bottom wall of the gripping member 23 in the longitudinal direction, and the gripping member 23 is bent downward substantially at a right angle as shown in FIG. In the horizontal state, an engagement piece 23a that engages with the upper side portion 24a of the back wall of the bending plate 24 is formed.

  The side plate 15 on the back side has a folded portion 15a folded at a right angle to the rear side at the left end, and a handle device similar to the above is also provided here.

  Next, the operation | movement at the time of conveyance of the apparatus main body 1 comprised as mentioned above is demonstrated. When pulling out the gripping member 23, pull the other end far from the rotation fulcrum with your finger, hold it with your hand, and use the fulcrum pin 28 as the rotation fulcrum, as shown by the arrow A in FIG. Rotate. When rotating to near horizontal, the interference portion 29a of the groove 29 provided on the upper surface of the side wall of the gripping member 23 interferes with the edge portion of the upper side portion 25a of the opening 25 to generate a load, but the interference portion 29a rotates. Since it is close to the fulcrum, it does not hinder the operation, and the interference is eliminated by further rotating it with a slight force. As shown in FIG. 4B, the upper side 25a of the opening 25 is held by the gripping member. 23, the engaging piece 23a provided at one end of the gripping member 23 is engaged with the upper side portion 24a of the back wall of the bending plate 24, and the gripping member 23 is projected in a horizontal state. Can do.

  Even if the hand is released from the gripping member 23 in this state, as shown in FIG. 6, the interference portion 29 a interferes with the upper side portion 25 a of the opening 25, and the gripping member 23 is held at the broken line position without falling. When the gripping member 23 is housed, if the other end of the gripping member 23 is rotated downward as shown by an arrow B in FIG. Is released, and thereafter it is stored in the storage portion 22 by its own weight.

  When the image forming apparatus is transported, two transporters crouch each other with the apparatus main body 1 sandwiched therebetween, and one transporter holds the two gripping members 23 with both hands, and the other transporter A hand is inserted into a recess (not shown) provided at two locations of the exterior part to hold the apparatus main body 1 and lift and convey it.

  At this time, as shown in FIG. 4 (b), a load of several percent of the weight of the main body acts on the carrier holding the holding member 23 as F0. In the gripping member 23, the edge surface of the upper side portion 25 a of the opening 25 of the folded portion 14 a (or 15 a) contacts the bottom surface of the groove 29 of the gripping member 23, and the bottom wall outer surface of one end portion of the gripping member 23 is the bent plate 24. It is held in contact with the edge surface of the upper side portion 24a of the rear wall. That is, when the force F0 is applied, the force acts on the upper side 24a of the rear wall of the bent plate 24 so that the rotational moment with the contact portion on the upper surface of the gripping member 23 as a fulcrum is balanced. The force F1 obtained by adding F0 and F2 from the balance of the force acts on the upper side portion 25a of the opening 25 of the folded portion 14a (or 15a). For this reason, when the apparatus main body 1 is lifted, the gripping member 23 is held by the folded portion 14a (or 15a) of the side plate 14 (or 15) and the bent plate 24, and no force acts on the fulcrum pin 28. Become. The fulcrum pin 28 is generally fixed to the side plate 14 by caulking, and the strength against the overturn of the apparatus main body 1 is not so strong. However, according to the present invention, it is not necessary to give the fulcrum pin 28 high strength. It becomes.

  A second embodiment of the handle device of the present invention will be described. 8 and 9 are a longitudinal sectional view and a transverse sectional view showing a state in which the gripping member of the handle device according to the second embodiment is rotated to the horizontal position and protruded. In these drawings, the same parts as those of the handle device according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 8 and 9, a hemispherical engagement protrusion 32 protrudes on the outer surface of one side wall of the gripping member 23 closer to the other end than the fulcrum hole 27 (see FIG. 4B). Has been. On the other hand, an engagement hole 33 through which the engagement protrusion 32 engages with the gripping member 23 projecting horizontally penetrates at a predetermined position on the side wall of the bending plate 24 that serves as a support wall of the storage portion 22. Is provided. As shown in FIG. 9, a compression coil spring 31 is inserted into the fulcrum pin 28 between the outer surface of the side plate 14 and the outer surface of the other side wall of the gripping member 23, and the gripping member 23 is always in the direction of the side wall of the bent plate 24. Is being energized.

  According to this configuration, even if the hand is released with the gripping member 23 protruding horizontally (see FIG. 4 (b)), the other side wall outer surface of the gripping member 23 is not bent by the urging force of the coil spring 31. It is pressed against the inner surface of the side wall, and the engagement protrusion 32 engages with the engagement hole 33 and is held without sagging. When the gripping member 23 is stored, if the other end of the gripping member 23 is rotated downward to disengage the engagement protrusion 32 and the engagement hole 33, the storage portion is held by the weight of the gripping member 23 thereafter. 22 is housed.

  A third embodiment of the handle device of the present invention will be described. FIG. 10 is a cross-sectional view illustrating a state in which the gripping member of the handle device according to the third embodiment is rotated to the horizontal position and protruded. In this figure, the same parts as those of the handle device according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 10, a friction pad 34 is inserted into the fulcrum pin 28 between the outer surface of one side wall of the gripping member 23 and the inner surface of the side wall of the bending plate 24. Further, a compression coil spring 31 is inserted into the fulcrum pin 28 between the outer surface of the side plate 14 and the outer surface of the other side wall of the gripping member 23, and the gripping member 23 is always biased toward the side wall of the bending plate 24. Yes.

  According to this configuration, even if the hand is released with the gripping member 23 protruding horizontally (see FIG. 4 (b)), the other side wall outer surface of the gripping member 23 is bent by the urging force of the coil spring 31. It is pressed against the inner surface of the side wall and is held without sagging by the frictional force of the friction pad 34. Moreover, since the strength of this frictional force does not depend on the rotational position of the gripping member 23, the gripping member 23 can be held not only in a horizontal state but also at an arbitrary position. In addition, since the frictional force does not move to the extent that the gripping member 23 is slightly moved with a gentle force, the gripping member 23 does not fall to the storage position, and the operability is improved. When the gripping member 23 is stored, if the other end of the gripping member 23 is rotated downward with sufficient force to overcome the frictional force, the gripping member 23 is stored in the storage portion 22 by its own weight. The

  As described above, according to the handle device of the present invention, the lock mechanism and the unlocking mechanism of the rotating gripping member are realized with a simple configuration using interference, engagement, friction, etc. The operability at the time of setting, storing and transporting can be improved.

  Moreover, although the cross-sectional shape of the rod-shaped gripping member is formed in a rectangular tube shape in the above-described embodiment, the present invention is not limited to this. For example, it may be a polygonal cylinder such as a triangle or a pentagon, or a cylinder.

  The present invention can be used in an image forming apparatus such as a copying machine, a facsimile machine, a printer, a scanner, or a multifunction machine having both functions.
