BACKGROUND OF THE INVENTION
The present invention relates to a handle used when opening or closing a door, a lid, or the like, or when carrying a trunk or the like.
[0002]
[Prior art]
As shown in FIG. 8, the inspection door 102 of the distribution box 100 is provided with a digging type handle 104. The handle 106 of the handle 104 falls into the base member 108 when not in use so as not to get in the way.
[0003]
However, this type of handle 104 has a large number of parts as shown in FIG. In addition, the base member 108 is fixed to the door 102 with screws 110 and nuts 112, and the cover 116 that covers the bearing 114 of the handle 106 is fixed to the base member 108 with screws 118, so that the assembly work is complicated. It was difficult to reduce man-hours. Furthermore, the screws 110 and 118 are exposed to the outside, and the appearance is not good.
[0004]
Further, since the cover 116 is press-worked and the handle 106 and the base member 108 are manufactured by die-casting aluminum, the manufacturing cost is high, and an unpleasant sound is generated when the metals slide, so there is an uncomfortable feeling. is there.
[0005]
Furthermore, although the soft cushion 98 is attached to the cover 116 and the impact sound with the handle 44 biased by the spring 120 is reduced, there is a risk that the precision parts in the distribution box 100 will vibrate due to the impact force.
[0006]
[Problems to be solved by the invention]
In view of the above facts, the present invention aims to reduce the number of parts and the manufacturing cost, to facilitate the assembly and improve the appearance, and to prevent the occurrence of a collision sound and an annoying sound of the handle. .
[0007]
[Means for Solving the Problems]
In the invention described in claim 1, a flat box-shaped resin base member is attached to the door. A bearing is integrally formed on the bottom plate of the base member , so that the number of parts can be reduced. The bearing rotatably supports a shaft connected to a resin handle.
[0008]
Further, biasing means is attached to the shaft body, and the handle is biased in the direction of tilting into the base member, and the handle is stored in a tilted state in the base member when not in use. For this reason, a handle sticks out from the door and does not get in the way.
[0009]
Further, a shaft damper supported by the bearing is connected to the shaft body, and attenuates the urging force of the urging means. As a result, the handle does not tilt vigorously and slowly falls down, giving a sense of quality, and since no impact force acts on the base member, it does not adversely affect electronic devices housed inside the door. . Furthermore, since the handle and the base member are formed of resin, the manufacturing cost can be reduced, and no annoying sound is generated when the metals slide.
[0010]
On the other hand, a locking member is formed on the base member, and the cover is fixed to the base member with one click by simply attaching the claw portion to the locking member while covering the shaft body, biasing means, and shaft damper with the cover. Is done. For this reason, the assembling work is simple, and the screw is not exposed to the outer surface, so that it looks good.
[0011]
According to the second aspect of the present invention, when the base member is fitted into the attachment port formed in the door, the boss provided on the door and the protrusion of the base member are engaged. Then, the base member is firmly fixed to the door by screwing the protrusion from the bottom surface side of the boss portion, and the screw is not exposed to the outside, so that the appearance is good.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 to 4, the handle 10 according to this embodiment is attached to the door 14 of the distribution box 12. The resin base member 16 of the handle 10 is fitted into an attachment port 18 provided in the door 14.
[0013]
The base member 16 includes a flat box-shaped storage unit 20 and a frame-shaped flange 22 that projects outward from the peripheral edge of the storage unit 20. On the back surface of the flange 22, there is provided a columnar protrusion 26 that engages with the boss portion 24 provided on the door 14 when the storage portion 20 is attached to the attachment port 18.
[0014]
A screw hole 28 is formed in the protrusion 26, and a screw 30 inserted from the bottom surface of the boss portion 24 is screwed in, so that the base member 16 is firmly fixed to the door 14. Further, a claw plate 32 protrudes from the outer wall 20A of the storage portion 20 and is locked to the rim portion of the mounting port 18 as shown in FIG. 6 to temporarily fix the base member 16 to the door 14, The screwing work is made easy.
[0015]
On the other hand, as shown in FIGS. 1 and 5, two shaft plates 36 and 38 are erected on the bottom plate 20 </ b> B of the storage unit 20. In the central part of the shaft plates 36 and 38, shaft holes 43 and 46 pass through coaxially with the shaft holes 40 and 42 provided in the side wall 20A of the storage unit 20.
[0016]
Further, the bottom plate 20B located in the vicinity of the side wall 20A is recessed in an arc shape, and shaft portions 50, 52 of a U-shaped handle 44 (molded of resin) in a plan view in the recess 48. Is installed. Thus, by providing the recess 48 in the bottom plate 20B, the movement of the shaft portions 50 and 52 is not interfered, and the handle 44 rotates smoothly.
[0017]
Further, a connecting hole 54 passes through the shaft portion 50. The connection hole 54 has an oval shape having a straight portion, and an I-cut portion of the shaft 56 that is pivotally supported at one end by the shaft hole 43 is fitted, and rotates together with the shaft 56. . Further, a small-diameter shaft portion 58 projects from the other end of the shaft 56, and this shaft portion 58 is supported by the shaft hole 40.
[0018]
Further, a torsion coil spring 60 is inserted through the shaft 56. One end of the torsion coil spring 60 is fixed to the shaft portion 50 of the handle 44, and the other end is fixed to the shaft plate 36, and the handle 44 is urged in a direction to fall to the bottom plate 20B.
[0019]
On the other hand, between the shaft plate 36 and the shaft plate 38, there are provided a pedestal 62 having a semicircular upper portion and a stop wall 64. A casing 68 of a shaft damper 66 having a cylindrical outer shape is fitted into the pedestal 62, and the stop wall 64 presses the end of the casing 68. A predetermined viscous resistance is applied to the rotating shaft 70 of the shaft damper 66 from a viscous body enclosed in the cylinder.
[0020]
An oblong connection hole 72 is formed on the end surface of the rotation shaft 70. The connection hole 72 is connected to an I-shaped connection portion 56 </ b> A projecting from one end of the shaft 56. Thereby, since the shaft 56 rotates at a predetermined rotational speed, the rotational speed of the handle 44 is restricted, and a high-class feeling can be produced.
[0021]
On the other hand, a circular connection hole 74 passes through the shaft portion 52 of the handle 44. A pin 76 supported by the shaft hole 46 of the shaft plate 38 and the shaft hole 42 of the side wall 20 </ b> A is inserted into the connection hole 74, so that the handle 44 can be rotated around the pin 76.
[0022]
When the resin cover 78 is attached to the base member 16, the plate piece 81 provided on the inner side of the upper plate 80 comes into contact with the head portion 76 </ b> A of the pin 76 so that it does not fall out of the shaft hole 46. .
[0023]
The cover 78 has a channel shape in a side view, and as shown in FIG. 2, the width of the upper plate 80 is set to cover the shaft damper 66, the shaft 56, and the like. Further, side plates 82 and 84 hang from the end portion of the upper plate 80 in the width direction.
[0024]
A plurality of claw portions 86 are formed on the outer surface of the side plate 82. As shown in FIG. 6, the claw portion 86 is locked to the upper end portion of the inclined wall 88 that rises obliquely from the bottom plate 20 </ b> B when the cover 78 is pushed into the base member 16. Thereby, the cover 78 can be attached to the base member 16 with one touch.
[0025]
Further, below the position where the claw portion 86 and the inclined wall 88 are locked, an insertion port 90 is formed at a position blocked by the inclined wall 88 so as not to be seen, and a jig is inserted from the back side of the bottom plate 20B. Thus, the locked state between the claw portion 86 and the inclined wall 88 can be released. Further, a claw portion 92 is also formed on the outer side of the side plate 84 and is locked in a locking hole 94 formed in the side wall 20A as shown in FIG.
[0026]
On the other hand, the bottom plate 20B on the side where the grip 44A of the handle 44 tilts is partially pushed upward, and the pushed portion serves as a base 96. A soft cushion 98 is affixed to the pedestal 96 and serves to alleviate the impact force when the grip 44A of the handle 44 collides.
[0027]
Next, the operation of the handle lock according to this embodiment will be described.
[0028]
Since the handle 44, the base member 16, and the cover 78 constituting the handle 10 are made of resin, the manufacturing cost can be reduced, and no annoying sound is generated when the metals slide.
[0029]
Further, shaft plates 36, 38 and the like are integrally formed on the base member 16 to reduce the number of parts. Furthermore, since the cover 78 can be attached to the base member 16 with one-fitting through the claw portions 86 and 92, the assembly work is easy, and the screw is not exposed to the outer surface as in the prior art. Clean and nice looking.
[0030]
A shaft damper is connected to the shaft 56 and the urging force of the torsion coil spring 60 is damped, so that the handle 44 does not tilt and tilts slowly so that a high-class feeling can be obtained. Since the soft cushion 98 relieves the impact force with the base member 16, it does not adversely affect the electronic equipment and the like housed inside the door 14. 7, instead of the soft cushion 98, the handle 44A of the handle 44 is received with a small area by three plate pieces 100 and the impact force is dispersed, thereby acting on the door. The impact force can be reduced.
[0031]
Further, when the storage portion 20 of the base member 16 is fitted into the mounting opening 18 formed in the door 14, the protrusion 26 engages with the boss portion 24, and the protrusion 26 is connected to the boss portion 24 from the bottom surface side with a screw 30. By stopping, the base member 16 is firmly fixed to the door 14, and the screw is not exposed to the outside as in the conventional case, so that the appearance of the door 14 is improved as shown in FIG.
[0032]
【The invention's effect】
Since the present invention has the above-described configuration, the number of parts and the manufacturing cost can be reduced, the assembling becomes easy and the appearance is improved. Moreover, it is possible to prevent the occurrence of a handle collision sound or an harsh sound.
