The axonometric chart of Fig. 2 and Fig. 4 and exploded perspective view are the schematic configuration of base 6 and the outward appearance of foot 5.Base 6 (with reference to Fig. 1, Fig. 4) is made of tubular frame 60 and cover 64.Tubular frame 60 is by slightly being oblong outside framework 61, being erected at a plurality of inner frames 62 of outside framework 61 inboards in length and breadth and the flat boards 63 that are arranged on above the inner frame 62 are formed.Cover 64 is arranged on the tubular frame 60 in the mode of the rotation section 54 of covering tubular frame 60 and foot 5.

The flange 55 that is positioned at the foot of foot 5 is provided with detent mechanism 7, and this detent mechanism 7 is used for and will is made the rotational fixation of the portion of attending a banquet 3 in the twist-lock position by the rotation section 54 of foot 5.The masseur 1 of present embodiment, above-mentioned rotation section 54 is with the position as twist-lock, the center of rotating angular range.Fig. 5 is the formation of detent mechanism 7.Fig. 6 (positioning states) and Fig. 7 (releasing positioning states) are the sectional views of detent mechanism 7.Detent mechanism 7 is set at the front side of foot 5, is made of base plate 71, axle 72, slide block 73, operating handle 74, spring 75 and tubular liner 76.

Base plate 71 is that the cross section of top opening is the elongated member of C font, and an end 713 is weldingly fixed on the flange 55 of foot 5.Near the front end of two side plates 711 of this base plate 71, inserting axle 72.Slide block 73 also is that the cross section of top opening is the shape of C font, is set at base plate 71 inboards and also can slides along two side plates 711 of base plate 71.On two side plates 737 of slide block 73, be formed with a pair of slotted hole 731.This slotted hole 731 as shown in Figure 5, and is not parallel with the base plate of slide block 73, but rearward the distance of (direction of foot 5) and base plate adds longways to tilt gradually, and inserting axle 72 with base plate 71.

These base plate 71 reason axles 72 and slide block 73 constitute, so slide block 73 is that the position that front and back end with the slotted hole 731 on two side plates 737 that are located at slide block 73 touches axle 72 is a limit with respect to the sliding scale of base plate 71.As shown in Figure 6, the position that axle 72 touches the front edge of slotted hole 731 becomes the rearmost end with respect to the sliding scale of the base plate 71 of slide block 73.At this moment and since axle 72 be positioned on the slotted hole 731 with the shortest position of the base plate of slide block 73 distance on, so the distance increase of the base plate of slide block 73 and base plate 71.Because this gap increases, so any end of the front and back of the base plate of slide block 73, can with the angular range that contacts above the base plate of base plate 71 in, be that the center is freely shaken with axle 72.When making slide block 73 to the slip foremost of sliding scale from this position, axle 72 will be at slotted hole 731 inner phase to rearward moving.As mentioned above, because the slotted hole 731 of two side plates of slide block 73 is not parallel with base plate, but rearward the distance of (direction of foot 5) and base plate adds longways to tilt gradually, so along with slide block 73 forwards moves, gap turn narrow between the base plate of the base plate of slide block 73 and base plate 71, thereupon, the axle 72 with slide block 73 is that the swing range at center also narrows down.Touch the position of the back edge of slotted hole 731 when axle 72, promptly, move to respect to the sliding scale of the base plate 71 of slide block 73 foremost the time, since axle 72 be positioned on the slotted hole 731 with the longest position of the base plate of slide block 73 distance on, therefore almost eliminate in the gap between the base plate of the base plate of slide block 73 and base plate 71, is that shaking of center is possible hardly with the axle 72 of slide block 73.

In addition, near the rear end 735 of base plate, the outstanding upward post 732 that is provided with.When the twist-lock position of the portion of attending a banquet 3 in regulation, (with reference to Fig. 4, Fig. 6's engaging recessed part 531 of this post 732 and the front center of the flange 53 that is arranged on foot 5 Fig. 7) fastens, and will attend a banquet 3 twist-lock.

Operating handle 74 usefulness screws 742 are installed on the front end 734 of slide block 73.As shown in Figure 8, expose a part the hole 64a of operating handle 74 from the cover 64 that is located at base 6, the recess 741 that the abutment of letting go when superincumbent first half forms operation is used.

Spring 75 is wind springs of the linearly prolongation in two ends, is set on the axle 72.This spring 75 is remained on the substantial middle position of 737 of two side plates of slide block 73 by tubular liner 76.In addition, an end 751 of spring 75 contacts with the bottom surface first half 734 of slide block 73, and the other end 752 passes slotted hole 736 on the base plate that is arranged on slide block 73, contacts and impose elastic force with the bottom surface 712 of base plate 71 downwards.When in the wings sliding position of slide block 73, as mentioned above, it is big that gap that the base plate of the base plate of slide block 73 and base plate 71 is 712 becomes, and slide block 73 is to be the state that the center can freely be shaken with axle 72, spring 75 freers the slide block 73 that shakes with elastic force, with its rear end 735 sides top upward.In view of the above, as shown in Figure 6, on the twist-lock position of the portion of attending a banquet 3, post 732 keep with the flange 53 that is arranged on foot 5 on the height that fastens of engaging recessed part 531, the portion 3 of attending a banquet is positioned at the positioning states of twist-lock.

In addition, when slide block 73 is positioned at the sliding position of forefront, as mentioned above, almost eliminate in the gap that the base plate of the base plate of slide block 73 and base plate 71 is 712, slide block 73 is to be under the almost impossible state of shaking of center with axle 72, the elastic force of slide block 73 antagonistic springs 75, its rear end 735 sides keep being pressed towards the state that the below is lived.In view of the above, under the state that positioning solution is removed as shown in Figure 7, post 732 remains on than on the low position of the flange 53 of the foot 5 with recess 531, can not hinder the rotation of the portion of attending a banquet 3.

In above-mentioned positioning states and location disarm state, utilize operating handle 74 can realize making the slip of slide block 73.As shown in Figure 6, if move on to disarm state, finger is placed in the recess 741 of operating handle 74 forwards (direction of Fig. 6 arrow A) and draws from positioning states.Owing to slide when slide block 73 and the position of slotted hole 731 that tilts and axle 72 are closed and tied up to variation, be accompanied by its gap of forwards moving with base plate 71 and diminish gradually, be that the swing range angle at center diminishes gradually with axle 72.Therefore, when slide block 73 is forwards mobile, Yi Bian Yi Bian the rear end 735 of base plate and post 732 are forwards mobile also mobile downwards.As Fig. 2 and shown in Figure 4, because being the place ahead central authorities at the periphery of flange 53, engaging recessed part 531 forms concavity, so just can remove both sides' fastening state as long as the post 732 of engaging is forwards moved.Like this, make post 732 and being fastened on of engaging recessed part 531 on the flange 53 that is arranged on foot 5 obtain on fore-and-aft direction and the short transverse both direction removing.So, as shown in Figure 7,, then post 732 is remained on than on the low position of the flange 53 of the foot 5 that recess 531 is arranged if up to becoming location disarm state pulling process handle 74 forwards, can not hinder the rotation of the portion of attending a banquet 3.

On the contrary, as shown in Figure 7, if move on to positioning states from the location disarm state, then rearward (direction of the arrow B of Fig. 7) is pressed into the recess 741 of operating handle 74.Along with slide block 73 rearward moves, become gradually greatly with the gap of base plate 71, be that the swing range angle at center becomes big gradually with axle 72.The slide block 73 that can freely shake, because the elastic force of spring 75, its rear end 735 and post 732 are pressed towards the upper limit of swing range.Therefore, when slide block 73 is rearward mobile, Yi Bian Yi Bian the rear end 735 of base plate and post 732 rearward move also is moved upward.At this moment, if attend a banquet portion 3 on the position of twist-lock of regulation, then engaging recessed part 531 with position that post 732 engage on, with post 732 moving and insert from the open side of engaging recessed part 531 rearward and upward, just engaging is firmly for both sides.Portion 3 is under the rotary state beyond the position of the twist-lock of regulation if attend a banquet, and then engaging recessed part 531 is not positioned on the position that engages with post 732, so can not engage with engaging recessed part 531 even post 732 rearward moves.This detent mechanism 7 in order to make above the post 732 unlike height below the flange 53, needs to set the size and the position relation of each parts when post 732 rearward moves to the position of flange 53.In view of the above, though when engaging recessed part 531 not the time with position that post 732 engages, the side of post 732 does not contact with the periphery of flange 53 yet, can make slide block 73 move to rear.At this moment, post 732 opposings become the following state of contact of the top and flange 53 of post 732 by the elastic force that spring 75 applies upward.So, position, the engaging recessed part 531 that portion 3 turns to the twist-lock of regulation in case attend a banquet move to post 732 directly over, then the thing that hinders post 732 to be moved upward because of spring 75 elastic force upward disappears, slide block 73 shakes and makes post 732 be pressed in the height that fastens with engaging recessed part 531, becomes the state that post 732 engages with engaging recessed part 531.

Because the masseur 1 of embodiment has above formation, so when the position of twist-lock of the portion of attending a banquet 3, rotate, lift when being provided with again after carrying by detent mechanism 7 lockings in regulation, the part of perimeter contacts with the face of setting, can prevent that base 6 is being provided with overturning on the face.In addition, because the operating handle 74 of detent mechanism 7 exposes the hole 64a from the cover 64 that is located at base 6, so on the position of user easy operating in the front side of foot 5.And then, owing to only need carry out the pulling out of operating handle 74/by advancing (the arrow A of Fig. 6 for the rotation/localized switching of the portion of attending a banquet 3, the arrow B of Fig. 7) shirtsleeve operation like this, so convenient use, even tramped with one's feet operating handle 74 mistakenly, owing to do not have the operation of push handle 74 downwards, can not remove the positioning states of the portion of attending a banquet 3 suddenly yet.

In the above-described embodiment, the twist-lock position of the portion of attending a banquet is the central authorities of the slewing area of horizontal direction, also can increase the quantity in the hole 531 that is provided with on the flange 53 of foot 5, and it is a plurality of that the twist-lock position is become.In addition, the mechanism that drive sources such as solenoid or cylinder replace operating operation handles 74 can be set also, rotation/location is switched in control and not shown switch such as the remote control drive source of interlock mutually that is provided with.
