并且，第一直管部35的长度方向中心线C1和第二直管部36的长度方向中心线C2在配置于手边操作管22的中央部附近的弯管部37交叉，由此，手边操作管22如上述那样在侧视中弯曲为山形状。 And, the longitudinal centerline C1 of the firststraight pipe portion 35 and the longitudinal centerline C2 of the secondstraight pipe portion 36 intersect at the bent pipe portion 37 disposed near the central portion of the hand-operatedpipe 22, whereby the hand-operated Thepipe 22 is curved in a mountain shape in side view as described above. the

第一直管部35是具有与延长管25的长度方向大致一致的长度方向中心线C1的管。 The firststraight pipe portion 35 is a pipe having a longitudinal centerline C1 substantially coincident with the longitudinal direction of theextension pipe 25 . the

第二直管部36由固定在集尘软管21的另一端部上的旋转管38、和旋转自如地轴支承旋转管38的手边操作管22的外轮廓部39构成。 The secondstraight pipe portion 36 is composed of a rotating pipe 38 fixed to the other end of thedust collecting hose 21 , and anouter contour portion 39 of thehand pipe 22 rotatably pivotally supporting the rotating pipe 38 . the

旋转管38是轴支承集尘软管21的接头，弯管部37为使第一直管部35与第二直管部36连通的弯头部。 The swivel pipe 38 is a joint that pivotally supports thedust collection hose 21 , and the elbow portion 37 is an elbow portion that communicates the firststraight pipe portion 35 and the secondstraight pipe portion 36 . the

另一方面，电动吸尘器1的把持部23是一体地形成在手边操作管22上的把手，以第一直管部35与第二直管部36的交叉部为起始端(具体而言以弯管部37为起始端)并列于第二直管部36而设置。 On the other hand, the grippingportion 23 of the electric vacuum cleaner 1 is a handle integrally formed on the operatingpipe 22 at hand, with the intersection of the firststraight pipe portion 35 and the secondstraight pipe portion 36 as the starting end (specifically, a curved The pipe portion 37 is the starting end) arranged in parallel with the secondstraight pipe portion 36 . the

这里，在本实施方式中，所谓交叉部，并不仅意味着交叉部，还作为也包括交叉部的旁边(附近)的用语使用。 Here, in the present embodiment, the term "intersection" does not mean only the intersection, but is also used as a term that includes the side (near) of the intersection. the

并且，具备沿相对于第一直管部35的长度方向中心线C1平行的方向 延伸的第一把持部41、从第一把持部41弯曲形成且在相对于第一直管部35的长度方向中心线C1交叉的方向上延伸的第二把持部42、设置为使其与第一把持部41及第二把持部42一起形成三角形状的软管保护部43、和设在第一把持部41的起始端部上的凹部44。 And, it is equipped with a first grippingportion 41 extending in a direction parallel to the longitudinal centerline C1 of the firststraight pipe portion 35, bent from the first grippingportion 41 and extending in the longitudinal direction relative to the firststraight pipe portion 35. The second grip part 42 extending in the direction where the center line C1 intersects, the hose protection part 43 provided so as to form a triangular shape with thefirst grip part 41 and the second grip part 42, and the hose protection part 43 provided on thefirst grip part 41 Therecess 44 on the starting end of the . the

另外，在本实施方式中，所谓平行方向，不是仅意味着平行，当然也包括得到本实施方式的效果的范围中的平行方向即大致平行方向。 In addition, in the present embodiment, the term "parallel direction" does not mean only parallel, but of course also includes parallel directions within the range of obtaining the effects of the present embodiment, that is, substantially parallel directions. the

与沿相对于上述第一直管部35的长度方向中心线C1交叉的方向延伸的第二把持部42的关系优选的是沿大致直角交叉的方向延伸。 In relation to the second grasping portion 42 extending in a direction intersecting the longitudinal centerline C1 of the firststraight pipe portion 35 , it is preferable to extend in a direction intersecting at substantially right angles. the

第一把持部41及第二把持部42都形成为棒状体，形成为电动吸尘器1的使用者能够用手抓握的粗细度及长度。 Both the firstgripping part 41 and the second gripping part 42 are formed in a rod shape, and are formed in such a thickness and length that a user of the electric vacuum cleaner 1 can grip it by hand. the

第一把持部41形成为，使其在侧视中从上述弯管部37的起始端部朝向与第二把持部42的连接部分，抓握粗细度逐渐变细。 Thefirst grip portion 41 is formed such that the thickness of the grip gradually becomes thinner from the starting end portion of the elbow portion 37 toward the connection portion with the second grip portion 42 in a side view. the

第二把持部42在侧视中使其与第一把持部41的连接侧向第一直管部35的方向稍稍前倾而设置。 The second gripping portion 42 is provided so that the connection side with the first grippingportion 41 is slightly inclined forward toward the direction of the firststraight pipe portion 35 in a side view. the

凹部44配置在第一把持部41的起始端部的下表面上，以使得当使用者用手抓握第一把持部41、将除了拇指以外的四指配置到由第一把持部41、第二把持部42及软管保护部43形成的三角形状的内侧时，食指钩挂在其中。 Theconcave portion 44 is arranged on the lower surface of the starting end portion of thefirst grip portion 41, so that when the user grasps thefirst grip portion 41 with his hand, the four fingers other than the thumb are arranged on the bottom surface formed by thefirst grip portion 41, thesecond grip portion 41, and thefirst grip portion 41. When the inner side of the triangular shape formed by the two holding parts 42 and the hose protection part 43, the index finger is hooked therein. the

此外，凹部44在侧视中形成为弧状，以使使用者容易钩挂食指。 In addition, theconcave portion 44 is formed in an arc shape in a side view so that the user can easily hook the index finger. the

可是，由于使用者的手的大小因人而异，所以从小指到拇指的距离也不同。这在如以往的把持部那样以钩挂小指的侧部的部分为基准抓握的把持部中，意味着抓握把持部的手的拇指被配置的地方因人而异。 However, since the size of the user's hand varies from person to person, the distance from the little finger to the thumb also varies. This means that the place where the thumb of the hand grasping the grip is placed differs from person to person in a grip that is gripped based on the side portion where the little finger is hooked as in the conventional grip. the

因而，在把持着把持部的状态下，能够容易用拇指操作的开关组的配置因人而异，以往的把持部与开关组的配置关系对于使用者而言并不一定是使用称手的。 Therefore, in the state of holding the grip part, the arrangement of the switch group that can be easily operated with the thumb varies from person to person, and the arrangement relationship between the conventional grip part and the switch group is not necessarily suitable for the user. the

另一方面，有关本实施方式的操作部24配置在当使用者将食指钩挂在凹部44中而抓握第一把持部41时、用抓握着第一把持部41的手的拇指的指尖容易按到的范围，具体而言配置在第一把持部41的起始端部的上表面上。 On the other hand, theoperation unit 24 according to the present embodiment is arranged so that when the user grasps thefirst grip unit 41 by hooking the index finger in theconcave portion 44 , the finger of the thumb of the hand gripping thefirst grip unit 41 is used. The range where the tip can be easily touched is specifically arranged on the upper surface of the starting end portion of the first grippingportion 41 . the

即，第一把持部41能够设定为对于任一使用者都以钩挂在凹部44中 的食指为基准而能够用拇指容易操作的开关组的配置。 That is, the first graspingportion 41 can be set to an arrangement of switches that can be easily operated with the thumb for any user with the index finger hooked in the recessedportion 44 as a reference. the

另外，操作部24可以考虑使用者将食指钩挂在凹部44中而用手抓握第一把持部41时的拇指的可动范围，来适当配置停止开关24a或起动开关24b。 In addition, thestop switch 24 a and thestart switch 24 b may be appropriately arranged on theoperation unit 24 in consideration of the movable range of the thumb when the user hooks the index finger in therecess 44 and grasps thefirst grip unit 41 . the

图4是表示有关本实用新型的实施方式的电动吸尘器的管部的侧视图。 Fig. 4 is a side view showing a pipe portion of the electric vacuum cleaner according to the embodiment of the present invention. the

图5是将有关本实用新型的实施方式的电动吸尘器的管部部分放大表示的侧视图。 It is a side view which enlargedly showed the pipe part part of the electric vacuum cleaner concerning embodiment of this invention. the

如图4及图5所示，把持部23的凹部44，当在第一直管部35上连接延长管25并且在延长管25的下端上连接吸入口体26而适当设定第一把持部41的抓握高度H时，比凹部44的位置的水平面h(参照图5)朝上方(图4、图5中，实线向视)陷入而形成。 As shown in Fig. 4 and Fig. 5, theconcave portion 44 of the holdingpart 23, when theextension pipe 25 is connected on the firststraight pipe part 35 and thesuction inlet body 26 is connected on the lower end of theextension pipe 25, the first holding part is properly set. When the grip height H is 41, theconcave portion 44 is sunken upward (see FIG. 4 and FIG. 5 , as viewed from the solid line) from the horizontal plane h (see FIG. 5 ) at the position of theconcave portion 44 . the

换言之，把持部23的凹部44使第一把持部41与凹部44的连接部分45位于比弧状的最高点t低而形成，以使得在适当的抓握高度下使用者的食指不会容易从凹部44脱离。 In other words, theconcave portion 44 of thegrip portion 23 is formed so that theconnection portion 45 between thefirst grip portion 41 and theconcave portion 44 is located lower than the arc-shaped highest point t, so that the user's index finger cannot easily fall from the concave portion at an appropriate grip height. 44 break away. the

第一把持部41的抓握高度H是第一把持部41的抓握中心距离被清扫面的高度，基于作为使用者最容易使用的标准的高度为约80cm、或作为考虑到吸入口体的前后行驶的高度为约90cm，设定为约80cm到约90cm。 The gripping height H of the first grippingportion 41 is the height of the gripping center of the first grippingportion 41 from the surface to be cleaned, based on the height of about 80 cm as a standard that is the easiest for the user to use, or as a height that takes into account the suction port body. The height of front and rear travel is about 90cm, and the setting is about 80cm to about 90cm. the

根据这样构成的有关本实施方式的电动吸尘器1及电动吸尘器用软管，使用者在抓握把持部23、特别是抓握第一把持部41时，使用者的食指钩挂在凹部44中并且牢牢地握入，能够可靠地紧握。 According to the electric vacuum cleaner 1 and the vacuum cleaner hose according to the present embodiment configured in this way, when the user grasps thegrip portion 23 , especially thefirst grip portion 41 , the user's index finger is caught in theconcave portion 44 and Grips in firmly for a reliable grip. the

由此，电动吸尘器1及电动吸尘器用软管，在使吸入口体26前后行驶时能够防止把持部23从使用者的手脱离，能够提高操作性。 As a result, the vacuum cleaner 1 and the hose for the vacuum cleaner can prevent thegrip portion 23 from coming out of the user's hand when thesuction port body 26 is moved back and forth, and operability can be improved. the

此外，根据电动吸尘器1及电动吸尘器用软管，由于将钩挂使用者的食指的凹部44形成为，使其以弧状陷入，所以能够减轻作用在食指上的负担(表面压力)，也不会使使用者感到重压。 In addition, according to the electric vacuum cleaner 1 and the hose for the electric vacuum cleaner, since theconcave portion 44 for hooking the user's index finger is formed so as to sink in an arc shape, the load (surface pressure) acting on the index finger can be reduced, and the Make the user feel stressed. the

进而，根据电动吸尘器1及电动吸尘器用软管，通过在适当的抓握高度H(例如约80cm到约90cm)朝上陷入的凹部44，能够提高第一把持部41紧握感而提高操作性。 Furthermore, according to the vacuum cleaner 1 and the hose for the vacuum cleaner, theconcave portion 44 sunk upward at an appropriate grip height H (for example, about 80 cm to about 90 cm) can improve the grip feeling of thefirst grip part 41 and improve the operability. . the

进而，根据电动吸尘器1及电动吸尘器用软管，由于具备从起始端部朝向与第二把持部42的连接部分抓握粗细度变细的第一把持部41，所以在 使用者抓握第一把持部41时能够提高从无名指到小指的紧握感而提高操作性。 Furthermore, according to the electric vacuum cleaner 1 and the hose for the electric vacuum cleaner, since the first grippingportion 41 is provided with the first grippingportion 41 whose thickness becomes thinner toward the connection portion with the second gripping portion 42 from the starting end portion, when the user grips the first gripping portion 42, When gripping theportion 41, the grip feeling from the ring finger to the little finger can be improved to improve operability. the

由于使用者的手的大小因人而异，所以从小指到拇指的距离也因人而异。这意味着，在将小指的侧部钩挂在突起上而抓握的以往的把持部中，拇指可达到的范围因人而异。 Since the size of the user's hand varies from person to person, the distance from the little finger to the thumb also varies from person to person. This means that in the conventional grip in which the side portion of the little finger is hooked to the protrusion and gripped, the reachable range of the thumb differs from person to person. the

即，以往的把持部因为手的大小而容易操作开关组的(手指容易达到的)范围不同，对于使用者而言使用称手性并不一定好。 In other words, the conventional grips have different ranges in which the switch group can be easily operated (accessible by fingers) depending on the size of the hand, and the chirality is not necessarily good for the user. the

另一方面，根据有关本实施方式的电动吸尘器1及电动吸尘器用软管，具备配置在当使用者将食指钩挂到凹部44中而抓握第一把持部41时、由抓握着第一把持部41的手的拇指的指尖容易按到的范围中、具体而言配置在第一把持部41的起始端部的上表面的操作部24。 On the other hand, according to the electric vacuum cleaner 1 and the hose for electric vacuum cleaners concerning this embodiment, when the user hooks the index finger in the recessedpart 44 and grasps the1st grip part 41, it is equipped with the1st gripping part 41 by which the user grips. Theoperation part 24 is arranged on the upper surface of the starting end part of thefirst grip part 41 in a range where the fingertip of the thumb of thegrip part 41 can easily be pressed. the

即，根据电动吸尘器1及电动吸尘器用软管，能够设定对于任一使用者而言都能够以钩挂在凹部44中的食指为基准而用拇指可容易地操作的操作部24的配置。 That is, according to the vacuum cleaner 1 and the vacuum cleaner hose, any user can set an arrangement of theoperation part 24 that can be easily operated with the thumb with the index finger hooked in the recessedpart 44 as a reference. the

因而，根据有关本实用新型的实施方式的电动吸尘器1及电动吸尘器用软管，能够具备不论使用者的手的大小如何都容易操作的把持部23。 Therefore, according to the vacuum cleaner 1 and the hose for vacuum cleaners concerning embodiment of this invention, thegrip part 23 which is easy to operate regardless of the size of a user's hand can be provided. the
