Description

  The present invention relates to a grip device used when transporting an image forming apparatus such as a copying machine, a printer, and a facsimile, and an image forming apparatus including the grip device.

  Conventionally, when an image forming apparatus is transported, a grip device that is integrally attached to the image forming apparatus is often used.

  For example, as shown in FIGS. 7A and 7B, the image forming apparatus 100 is provided with two opening / closing covers 101 on one side surface of the apparatus. Inside the opening / closing cover 101, the rotary handle 1 constituting the handle device 200 is arranged (see, for example, Patent Document 1).

  The rotary handle 1 has a configuration in which the tip end portion is rotated upward to be exposed to the outside of the device (upper rotary handle), or a configuration in which the tip end portion is rotated downward to be exposed to the outside of the device (downward rotation). There is a dynamic handle).

  An explanation will be given by taking as an example a handle device provided with an upward-rotating handle. Normally, as shown in FIG. 8, the handle 1 includes a height of the load receiving surface 10 of the housing member 4 of the image forming apparatus 100 that contacts when the handle 1 is in a horizontal state, and a rotation center line X of the handle 1. The height of −X is provided at the same horizontal position, and the load generated by the handle 1 with respect to the load receiving surface 10 is received in the vertical direction. Furthermore, the load receiving surface 10 and the fixing surface (handle fixing portion) 2A of the handle stay 2 holding the handle 1 rotatably about the rotation center shaft 3 with respect to the image forming apparatus main body (housing member) 4 are as much as possible. Basically it is close.

  This is because the load B is received vertically, so that the rotational moment A acting on the load receiving surface 10 suppresses the stress B or the stress C that depresses the load receiving surface 10 caused by the variation in the height of the load receiving surface 10. It is. In addition, the compressive strength of the material is effectively used to improve the load resistance of the handle 1 and the housing member 4, and further, the stress applied to the fixing surface (handle fixing portion) 2A of the handle stay 2 is reduced. In order to suppress deformation around the handle fixing portion.

  As shown in FIG. 9, the height of the load receiving surface 10 and the height of the rotation center line XX of the handle 1 are not the same horizontal position, or as shown in FIG. 10, the load receiving surface 10 and the handle stay 2 When the fixed surface 2A is separated, the stress B generated by the rotational moment A acting on the load receiving surface 10 increases, and as a result, the housing member 4 and the fixed portion 2A of the handle stay 2 are deformed.

  11 and 12, the load receiving surface 10 and the fixing surface 2A of the handle stay 2 are combined, and the height of the rotation center line XX of the handle 1 and the height of the load receiving surface 10 are set to the same horizontal position. The structure of the handle stay 2 is shown. When configured as in this example, as described above, the load receiving surface 10 caused by variations in the height of the load receiving surface 10, that is, the load receiving member 10 a is inclined by the stress B or the stress C that tilts the load receiving member 10 a. The member 10a falls, and as a result, the handle stay 2, the handle stay fixing portion 2A, and the housing member 4 are deformed.

  In either case, the casing member 4 or the handle stay 2 is made thicker or a reinforcing part is added to ensure the strength. However, this leads to an increase in the cost and weight of the product.

JP 2004-262202 A

For example, the handle 1 is configured to be pulled out of the image forming apparatus by opening the opening / closing cover 101. The

  Hereinafter, the grip device 200 will be described in more detail.

  Referring to FIGS. 1, 2A, 2B, and 3, the handle device 200 holds the rotary handle 1 and the handle 1 rotatably, and the handle device 200 is held in the image forming apparatus main body. (That is, a support sheet metal (hereinafter referred to as “grip stay”) 2 for attachment to the housing member 4. The handle 1 is an elongated member extending in the longitudinal axis direction, and one end portion 3a thereof is pivotally supported on the handle stay 2 by a rotation center shaft 3.

  In particular, as will be understood with reference to FIGS. 2A and 2B, the handle stay 2 includes a side plate 21 that is formed in an elongated, substantially rectangular shape extending in the vertical direction in parallel to each other, and both side plates 21. , 21 and a connecting plate 22 that connects the top portions of the base plate 23 with a substantially U-shape with an open lower portion. One side edge portion extending in the vertical direction of each side plate 21 is a plate-like member that is bent in a direction orthogonal to the side plate 21 and in a direction opposite to each other and arranged symmetrically. Two handle stay fixing portions 24, 24 are formed. Each handle stay fixing portion 24 is formed with a screw hole 25 for fixing the handle stay 2 to the housing member 4 forming a part of the main body of the image forming apparatus.

  A concave notch 26 is formed between the side plates 21 and the handle stay fixing portion 24 above the side plates 21 and 21. A load receiving portion 27 is provided at one end of the connecting plate 22. That is, one end of the connecting plate 22 is bent downward in the vertical direction (90 °) and enters the cutout portion 26, and a load receiving portion (hereinafter referred to as “load receiving portion”) that is a plate-like member. 27) is formed. Furthermore, the edge part of the both-sides plates 21 and 21 located in the notch part 26 is extended in the direction of the load receiving board 27, and the protrusion part 28 as a backup part of the load receiving board 27 protrudes and is formed. ing. The tip of the projection 28 is formed on the inner surface of the load receiving plate 27 bent perpendicularly to the connecting plate 22 (that is, a handle stay load receiving portion backup surface, which will be described in detail later) 7 with a gap (Δ (T0 ≦ 0.5 mm) is in contact (ΔT0 = 0) or close.

  The handle stay 2 configured as described above is fixed to the image forming apparatus main body by attaching a handle stay fixing portion 24 to a housing member 4 which is a plate-like member forming a part of the image forming apparatus main body in this embodiment. The That is, as shown in FIG. 1, the handle stay 2 has a rectangular base portion 23 inserted through a rectangular hole 4 </ b> A formed in the housing member 4, and each handle stay fixing portion 24 is inserted into the handle stay fixing portion 24. The casing member 4 is brought into contact with the casing member 4. And the handle stay fixing | fixed part 24 is fixed to the housing | casing member 4 with the screw | thread 5 using the screw hole 25. As shown in FIG.

  At this time, as shown in FIG. 3 and FIG. 2B, the plate-like housing member 4 has the outer surface 27 a of the load receiving plate 27 in the notch recess 26 of the handle stay 2 and the handle stay fixing portion 24. It arrange | positions so that it may be located in the clearance gap part 29 between the inner side surfaces (namely, handle-stay housing | casing fixed surface) of this.

  As described above, the housing member 4 is attached to the gap portion 29 between the outer surface 27a of the load receiving plate 27 and the handle stay housing fixing surface 8, which has a size T. The gap 29 having a size T is set to a size T in which a minimum gap (backlash) ΔT necessary for assembling the handle stay 2 to the housing member 4 is generated. Originally, it is desired that there is no gap (back) ΔT on assembly, but on assembly, a gap (back) ΔT exceeding 0 mm and about 0.5 mm is required.

  The handle 1 is rotatably supported by the handle stay 2 by a rotation center shaft 3 inserted through a shaft hole 30 formed through both side plates of the handle stay 2.

  In this embodiment, the handle 1 is an elongated member extending in the longitudinal axis direction in which a cross-sectional shape opened upward is a U-shape. 1 and 3, the left end of the handle 1 is the support portion 3a of the rotation center shaft 3, and the support portion 3a is inserted between the side plates 21 and 21 of the handle stay 2. Then, it is rotatably supported by the side plates 21 and 21 by the rotation center shaft 3.

  With such a configuration, the handle 1 has a rotation center O on the rotation center shaft 3, and is rotated and lifted to the outside of the apparatus main body during transportation, and is installed at a horizontal position (operation position). In the state, it is stored inside the apparatus main body. That is, the handle 1 is an upward rotating handle.

  In this embodiment, when the handle 1 is rotated to the horizontal position (operating position) about the center O of the rotation center shaft 3, the upper edge 1 a, 1 a of the handle 1 is loaded with the load of the handle stay 2. It strikes against the lower end surface of the plate 27, that is, the butting surface (hereinafter referred to as “grip stay load receiving surface”) 6. That is, the height of the center line (rotation center line) XX of the rotation center shaft 3 and the handle stay load receiving surface 6 are set at the same horizontal position. That is, the contact position between the handle 1 rotated to the operating position and the handle stay load receiving surface 6 is the same height position as the rotation center line XX set to the horizontal position. Usually, the distance T0 between the rotation center O of the handle 1 and the handle stay load receiving surface 6 is about 5 mm to 50 mm.

  As described above, in the present embodiment, in the handle device 200, the inner side surface 8 of the handle stay fixing portion 24 is parallel to the outer side surface 27 a of the load receiving plate 27. Further, the load receiving plate 27 includes a protrusion (backup portion) 28 and a housing that can support the backup surface 7 in a right angle direction with a minimum gap that can be pressed with the same part, a space exceeding 0 mm, and a space of about 0.5 mm. It is sandwiched and assembled by the body member 4. In other words, the handle stay 2 is configured such that the handle 1 is in perpendicular contact with the handle stay load receiving surface 6 below the load receiving plate 27 during assembly. Further, the handle stay 2 is arranged in the gap 29 between the handle stay load receiving plate 27 and the handle stay housing fixing surface 8 by using the housing member 4 as an intermediate interpolation member when the handle 1 and the handle stay load receiving surface 6 come into contact with each other. The housing 5 is screwed to the housing member 4 with a screw 5 so that a minimum gap is generated.

  Here, when the apparatus is transported, as shown in FIG. 3, the handle 1 is pushed upward and a load is applied to the handle stay load receiving surface 6. As shown in FIG. 3, when the height of the handle stay load receiving surface 6 is higher than the center line height of the rotation center shaft 3, the handle stay load receiving surface is caused by the rotational moment A acting on the handle stay load receiving surface 6. A stress B that deforms 6 in a direction approaching the rotation center axis 3 is generated. When the height of the handle stay load receiving surface 6 is lower than the center line height of the rotation center shaft 3, a stress C that deforms the handle stay load reception surface 6 in a direction away from the rotation center shaft 3 is generated.

  When a stress B that deforms the handle stay load receiving surface 6 in a direction approaching the rotation center axis 3 is generated, the handle stay load receiving surface 6, that is, the load receiving plate 27, the backup surface 7 and the tip of the projection 28. The gap ΔT0 with the part falls down. However, when the backup surface 7 of the load receiving plate 27 abuts against the protrusion 28, it cannot fall any further. When a stress C that deforms the handle stay load receiving surface 6 in a direction away from the rotation center axis 3 is generated, the outer surface 27a of the load receiving plate 27 when the handle stay load receiving surface 6 is fixed to the housing member 4, and the housing member The gap ΔT with 4 falls. And it cannot fall any more when it hits the casing member 4 fixed by the handle stay casing fixing surface 8. That is, with such a configuration, it is possible to suppress deformation of the load receiving plate 27 due to upward pushing of the handle 1 rotated to the operating position.

  That is, according to this embodiment, when the handle 1 abuts against the load receiving surface 6 of the handle stay load receiving plate 27, the handle 1 is deformed in a direction close to the rotation center shaft 3. The stay load receiving plate 27 abuts against the protrusion 28 and maintains its posture. Further, when the load receiving surface 6 is deformed in a direction away from the rotation center shaft 3, the handle stay load receiving plate 27 abuts against the housing member 4 and maintains its posture.

  In this way, the clearance ΔT0 between the backup surface 7 of the load receiving plate 27 and the projection 28 and the clearance ΔT between the load receiving plate 27 and the housing member 4 when being fixed to the housing member 4 are managed. As a result, the load received from the handle 1 can be received at a right angle by the handle stay load receiving surface 6, that is, the load receiving plate 27. As a result, by utilizing the compressive strength of the material, the disadvantage of the sheet metal part that is weak against the force in the bending direction is compensated, and the handle stay 2, the fixing portion of the handle stay 2 and the casing member 4, and the deformation of the periphery thereof It is possible to obtain a high load capacity that can prevent the above.

Example 2

  In the present embodiment, the overall configuration of the handle device 200 is the same as that of the first embodiment. Therefore, the description of the overall configuration of the handle device 200 of the first embodiment is used, and the characteristic part of the present embodiment is described below. explain.

  In this embodiment, as shown in FIGS. 4A and 4B, in addition to the configuration of the first embodiment, the handle stay load receiving plate 27 is fixed to the housing member 4 with screws 9.

  More specifically, in the first embodiment, the casing member 4 having a plate shape is inserted into the gap portion 26 formed between the load receiving plate 27 and the fixing portion 24 and fixed to the load receiving plate 27. The housing member 4 is fixed to the fixing portion 24 with screws 5. On the other hand, in the present embodiment, the housing member 4 positioned between the fixing portions 24 and 24 sandwiched between the load receiving plate 27 and the fixing portions 24 and 24 is attached to the load receiving plate 27 with screws. Stop and fix.

  As described above, in this embodiment, the screw receiving hole 27 b is formed in the load receiving plate 27, and the load receiving plate 27 and the housing member 4 are integrated by being drawn into the housing member 4 with the reinforcing fixing screw 9. As a result, gaps in the configuration of the housing member 4, the handle stay load receiving plate 27, and the handle stay housing fixing surface 8 can be eliminated. Accordingly, the housing of the handle stay housing fixing surface 8 and the load receiving plate 27 when the handle stay load receiving surface 6 is fixed to the housing member 4 when a stress C that deforms the grip stay load receiving surface 6 in the direction away from the rotation center axis 3 is generated. The falling deformation of the gap ΔT with the body member 4 can be eliminated. And the perpendicularity at the time of receiving the load received from the handle 1 is raised, the accuracy received in the compression direction of the material is improved, and the load resistance can be improved. At the same time, the housing member 4 becomes a reinforcing plate of the handle stay load receiving plate 27 by being integrated, so that the bending strength of the handle stay load receiving plate 27 can be improved and the load resistance of the handle portion can be improved. .

Example 3
Next, a third embodiment of the handle device 200 according to the present invention will be described with reference to FIG.

  In the present embodiment, the overall configuration of the handle device 200 is the same as that of the first and second embodiments. Therefore, the description of the overall configuration of the handle device 200 of the first and second embodiments is used, and the present embodiment is described below. The characteristic part of will be described.

  In the present embodiment, as shown in FIG. 5, in addition to the configurations of the first and second embodiments, the end surface position 4a of the housing member 4 and the height of the handle stay load receiving surface 6 are set to the same height. The With this configuration, the load per unit area with respect to the load received from the handle 1 is reduced without increasing the number of parts.

  That is, the rotational moment A acting on the handle stay load receiving surface 6 and the load receiving surface equivalent portion 4a of the housing member 4, and the handle stay load receiving surface 6 and the load receiving surface equivalent portion 4a of the housing member 4 generated thereby. Can be dispersed. That is, in this embodiment, the stress B or the stress C is distributed to the handle stay load receiving surface 6 and the load receiving surface equivalent portion 4 a of the housing member 4, so that the handle stay load receiving surface 6 and the housing member 4 are dispersed. The bending strength of the load receiving surface equivalent portion 4a can be improved, and the load resistance of the handle portion can be improved.

Example 4
Next, with reference to FIGS. 6A and 6B, a fourth embodiment of the handle device 200 according to the present invention will be described.

  In the present embodiment, the overall configuration of the handle device 200 is the same as that of the first embodiment. Therefore, the description of the overall configuration of the handle device 200 of the first embodiment is used, and the characteristic part of the present embodiment is described below. explain.

  In this embodiment, as shown in FIGS. 6 (a) and 6 (b), unlike the first embodiment, the height of the handle stay load receiving surface 6 is the centerline height (line) of the rotation center shaft 3 in the horizontal state. X−X)) is slightly higher (ΔH). That is, in the first embodiment, the handle 1 is configured such that the rotation axis center line XX that contacts the handle stay load receiving surface 6 contacts the handle stay load receiving surface 6 in the horizontal position. On the other hand, in the present embodiment, the rotation axis center line XX that contacts the handle stay load receiving surface 6 contacts the handle stay load receiving surface 6 when it is further rotated by an angle θ from the horizontal position. It is supposed to touch.

  For example, as described above, the height ΔH is the height of the horizontal center line when the distance T0 between the rotation center O of the handle 1 and the handle stay load receiving surface 6 is about 5 mm to 50 mm. It is preferably not the same as (Line XX), that is, more than 0 mm and smaller than about 1 mm.

  As a result, the stress generated by the rotational moment A acting on the handle stay load receiving surface 6 is a stress B that deforms the handle stay load receiving surface 6 in a direction approaching the rotation center axis 3. Using this stress B, the direction in which the handle stay load receiving plate 27 is deformed is managed so as to face the backup surface 7 side, that is, the protruding portion 28 side. Thereby, the handle stay load receiving surface 6 can be configured such that the gap (ΔT0) between the tip end portion of the projection 28 and the backup surface 7 of the load receiving plate 27 is tilted. Accordingly, as shown in FIG. 6A, the load can be received substantially perpendicular to the handle stay load receiving surface 6 without being sandwiched and pressed by the casing member 4. As a result, by using the compressive strength of the material, the disadvantage of the sheet metal part that is weak against the force in the bending direction is compensated, and the grip stay 2, the fixing portion of the handle stay 2 and the casing member 4, and the deformation of the periphery thereof are reduced. It is possible to obtain a high load capacity that can be prevented.
