The specific embodiment

[051] with reference now to accompanying drawing, described accompanying drawing is the purpose that is used to illustrate the preferred embodiment of baby seat, rather than is used to limit purpose, and Fig. 1 shows baby 12 is supported on and takes one's seat the position and baby 12 is retained in baby seat 10 in the baby seat 10.Baby 12 does not have flourishing muscle and does not need association how themselves to be stabilized in (referring to Fig. 1) in the position of taking one's seat yet.But, in the time of in being placed in the position of taking one's seat, baby 12 tend to swing to their side or after be poured on their head.In some cases, it is desirable to be supported on the position of taking one's seat for baby 12.By by way of example rather than ways to restrain, the position of taking one's seat is the optimum position when father and mother give baby's 12 feedings.In addition, because baby's 12 notice scopes are shorter, so thereby it is desirable to equally baby 12 is retained in the position of taking one's seat in the baby seat 10 concentrates baby's notice when some time (for example in the feeding process).Baby 12 can move around and can divert one's attention from other targets and the incident of generation around the baby 12.But father and mother must give baby's 12 feedings and attempt to keep the notice of baby 12 between feeding period.Advantageously, baby seat 10 can be supported on baby 12 in the position of taking one's seat and baby 12 is retained in the position of taking one's seat in the baby seat 10.

[052] by by way of example rather than ways to restrain, as shown in Figure 2, baby seat 10 can comprise seat support 14, backrest 16, two side support members 18 and front pillars 20.Seat support 14 can have upper surface 22, and baby 12 can sit on this upper surface 22.The upper surface 22 of seat support 14 can be become size and is configured to receive baby 12 buttocks.Preferably, thus the upper surface 22 of seat support 14 can have the buttocks that curve construction cosily receives baby 12.In this manner, in the time of in sitting in baby seat 10, because the comfort level of baby seat 10, baby 12 will can not divert one's attention.Thereby backrest 16 can be attached on the seat support 14 and vertically extend upward support baby 12 following back and/or preferably go up back.Thereby the front surface 24 of backrest 16 can by shaped form be attached to seat support 14 and substantially vertically extend upward baby 12 is supported to the position of taking one's seat.

[053] two side support member 18 can be attached to seat support 14 and also can be attached on the backrest 16 at its transverse side.Side support member 18 also can be linked to seat support 14 and vertically extends upward with curve form.Two side support members 18 also can by curve be attached to backrest 16.Front pillar 20 can extend upward (referring to Fig. 3) vertically and can be linked to seat support 14 with curve form from the front portion 26 of seat support 14.As shown in Figure 3, the front portion 26 of seat support 14, front pillar 20 and two side support members 18 limit two grooves 28, and described groove 28 cosily receives baby 12 leg 30 (referring to Fig. 1) in the time of can be become size and be configured in baby 12 sits in baby seat 10.

[054] seat support 14, backrest 16, two side support members 18 can limit the chamber with bulbous shaped structure, thus buttocks, leg 30 and back that described bulbous shaped structure is fitted to each other and cosily receives baby 12.As shown in Figure 2, the

upper surface

32,34 of backrest 16 and two side support members 18 can have the oblique structure that has summit 36, and this summit 36 terminates in the mid portion of backrest 16.The upper surface 34 of described two side support members 18 supports baby's elbow and arm when preferably being become to be of a size of, to be configured to and be positioned as in baby 12 sits in baby seat 10, as shown in Figure 1.

[055] front portion 26 (referring to Fig. 3) of seat support 14 can highly be higher than the rear portion 38 (referring to Fig. 2) of seat support 14.Therefore, in the time of in baby 12 sits in baby seat 10, his/her thigh upwards was raised on the buttocks of infants when baby 12 leaned to backward.Because baby's 12 muscle are undeveloped and the baby can not coordinate his/her motion, so baby 12 will be difficult to he or she is lifted to outside the baby seat 10 by oneself.Therefore, baby 12 is retained in the baby seat 10.Preferably, seat support 14 is angled about 15 and spends between 45 degree, and preferably is angled the inclination of about 33 degree.

[056] can make seat support 14, backrest 16, two side support members 18 and front pillars 20 by for example soft material of polyurethane, rubber or other conforming materials (compliantmaterial).Seat support 14, backrest 16, two side support members 18 and front pillar 20 can limit the base 40 (referring to Fig. 1) of baby seat 10 jointly.As Fig. 7, Figure 18, Figure 19 and shown in Figure 20, the base 40 of baby seat 10 can have the cavity 42 of band outer perimeter supporting member 44.Outer perimeter supporting member 44 can have a plurality of nets 46 (referring to Fig. 7), and described net 46 makes outer perimeter supporting member 44 and seat support 14 interconnection.Thereby net 46 can extend to the lower surface 48 (referring to Fig. 1 and Figure 18) of outer perimeter supporting member 44 provide additional support for baby seat 10.

[057] baby seat 10 can have pallet 50 (referring to Fig. 1) or the pommel 52 (referring to Fig. 8) that is attached to removedly on the front pillar 20 (referring to Fig. 2).When pallet 50 or pommel 52 are attached to front pillar 20 and baby 12 when sitting in the baby seat 10, pallet 50 or pommel 52 extend across baby's leg at least in part.In this manner, baby 12 is retained in the baby seat 10, because pallet 50 or pommel 52 stop that the baby drops out the path of baby seat 10.

[058] shown in Fig. 1-6, pallet 50 can be attached on the front pillar 20 removedly.When pallet 50 was attached on the front pillar 20, the lateral part 54 (referring to Fig. 5) of pallet 50 can extend across groove 28 and side support member 18.Therefore, pallet 50 and groove 28 provide an aperture, thereby baby's leg 30 can in placely be retained in the position of taking one's seat in the baby seat 10 with baby 12 by this aperture is locked.Pallet 50 can have flat upper surface 56, is formed with ridge 58 around this upper surface 56, as shown in Figure 1.Thereby upper surface 56 can be basically parallel to ground allows father and mother that food or other things are placed on the upper surface 56 when giving baby's 12 feedings.If liquid is spread across on the upper surface 56 of pallet 50, then ridge 58 controls are flowed and are prevented to flow on the ground or from upper surface 56 and flow out.

[059] shown in Fig. 2-6, pallet 50 can be attached on the front pillar 20 removedly via the public member of first embodiment and the cooperation of female member 60,62 (with reference to figure 4 and Fig. 5).Can use screw 66 that public member 60 is fixed to the bottom surface 64 of pallet 50, as shown in Figure 5.Public member 60 can have the flexible lever 68 of two outside bias voltages.The transverse side of lever 68 can have at least one tooth 70, and described tooth 70 can be engaged in the spline 71 of female member 62.Can come inside extrusion lever 68 by the distal portions 72 (referring to Fig. 5) of presses lever 68, as shown in Figure 6.By presses lever 68, the tooth 70 of lever 68 also moves inward.When the far-end of lever 68 was released, tooth 70 and lever 68 outwards moved.

[060] public member 60 can have the flange 74 (referring to Fig. 3 and Fig. 5) in pointing to, and the flange 74 in the described sensing can be matched with the outer flange 76 (referring to Fig. 3 and Fig. 4) of sensing of female member 62.The outer flange 76 of the sensing of female member 62 can be placed on the upper surface 78 of front pillar 20.The flange 76 of female member 62 and the upper surface 78 (referring to Fig. 4) of front pillar 20 form groove, and this groove can receive the flange 74 of public member 60 when being attached to pallet 50 on the baby seat 10 and more specifically being attached on the front pillar 20, as shown in Figure 3.When the flange 74 of public member 60 was inserted in the groove, because the interference between the

mating flanges

74,76, pallet 50 can upwards not mentioned.Female member 62 can be molded in the front pillar 20, be adhesive on the front pillar 20 or via any means discussed here or well known in the art and otherwise be attached on the front pillar 20.Can use hard material (for example plastics) to make female member 62.

[061] same, female member 62 has first row and the second row spline 71, and it inwardly is directed toward each other, as shown in Figure 4.The first and second row splines 71 can be become size and are configured to engage the tooth 70 of public member lever 68.Particularly, when pallet 50 is attached on the front pillar 20, thereby the distal portions 72 that father and mother can extrusion lever 68 moves inward lever 68 and respective teeth 70.Than the tooth of the spline 71 of female member 62, the width of public member tooth 70 is narrower.The tooth of the spline 71 of tooth 70 inswept female members 62 of the lever 68 of public member 60, thus allow the flange 74 of public member 60 to be inserted in the upper surface 78 formed grooves by the flange 76 of female member 62 and front pillar 20.In case pallet 50 is positioned, the distal portions 72 of trip lever 68 then, thereby the outside tooth 70 of shift lever 68 and make it to be engaged in the spline 71 of female member 62.In this manner, pallet 50 is optionally located, and can not deviate from baby 12 ground and be pushed to preceding or after baby 12 ground are pushed to.Thereby the tooth 70,71 that can make public and female member 60,62 by the distal portions 72 of depress lever 68 is disengaged and make the tooth 70 of lever 68 engage the corresponding spline 71 of female member 62 by trip lever 68 thereupon, thereby adjusts the forward/backward position of pallet 50.

[062] in use, thus can remove pallet 50 from the front pillar 20 of baby seat 10 allows easily to remove baby 12 from baby seat 10.Reason is, when pallet 50 is attached to front pillar 20, removes baby 12 thereby father and mother carry baby 12 on cannot be simply from baby seat 10.But, thereby must making baby 12 leg skid off the aperture that is formed by groove 28 and pallet 50, father and mother remove baby 12 from baby seat 10.Because pallet 50 is attached to front pillar 20 removedly, so thereby father and mother can remove pallet 50 from front pillar 20 to be helped to remove baby 12 from baby seat 10.After removing pallet 50, thus baby 12 can by on carry from baby seat 10 and removing.In a similar manner, thus can remove pallet 50 from front pillar 20 helps baby 12 to sit in the baby seat 10.

[063] owing to the back azimuth degree of seat support 14, baby's 12 back lean on backrest 16 in the baby seat 10 thereby baby 12 is retained in.In addition, by pallet 50 being attached on the front pillar 20 baby 12 can being retained in the baby seat 10.When pallet 50 was attached on the front pillar 20, pallet 50 extended across groove 28.Groove 28 and pallet 50 form the aperture, and baby 12 leg 30 is placed in by this aperture.When baby 12 leg 30 was placed in this aperture, baby 12 cannot oneself rise to him or she outside the baby seat 10 simply.

[064] in yet another aspect, pallet 50 can be replaced by pommel 52, as shown in Figure 8.Fig. 8 shows second embodiment of baby seat 10.Thereby pommel 52 can have bulbous shaped structure and soft outer surface prevents that when baby 12 catches this pommel 52 baby 12 from hurting he or she oneself.Pommel 52 can and be placed with from front pillar 20 outside horizontal expansions and cross at least in part by front pillar 20, seat support 14 and two side support member 18 formed grooves 28.In this manner, the baby can find that it is difficult to he or she is risen to outside the baby seat 10 by oneself in the time of in sitting in baby seat 10, because the space between pommel 52 and the side support member 18 is less than the overall diameter of baby's leg 30.More specifically, the distance that the outer perimeter 80 of pommel 52 and two side support members 18 limit thereby pommel 52 can laterally stretch out is less than the overall diameter of baby's leg.In this manner, pommel 52 produces additional reservation power when baby 12 attempts oneself to be raised to him or she outside the baby seat 10.Baby's leg contacts pommel 52 and two side support members 18 simultaneously.Because the space between pommel 52 and two the side support members 18 less than the overall diameter of baby's leg, breaks away from baby seats 10 so prevent baby 12.

[065] wishes when baby seat 10 removes baby 12 as father and mother, enlarge space between front pillars 20 and two the side support members 18 thereby can remove pommel 52 from front pillar 20.At this moment, father and mother or nurse can be lifted out baby seat 10 with baby 12.Pommel 52 shown in Fig. 8 can promptly use public affairs and the

female member

60,62 that cooperates to be attached to removedly on the front pillar 20 to Fig. 1-6 similar mode of being described.As the description about Fig. 1-6, female member 62 can be molded in the front pillar 20.Equally, public member 60 can be molded in the pommel 52.

[066] Fig. 9 shows the viewgraph of cross-section that is attached to the pommel 52 on the front pillar 20 removedly of the 3rd embodiment.Via being attached to public member 82 on the pommel 52 and the female member 86 that is attached on the front pillar 20 pommel 52 is attached on the front pillar 20 removedly.Public member 82 can comprise lever left 84a and right lever 84b, and described lever 84a, 84b can lie across between off-position and the pressing position.Preferably, compare with right lever 84b, lever left 84a can have the mirror image structure.Left and right lever 84a, 84b can be biased outwardly, and can move inward a left side and right lever 84a, 84b by the finger receipts surface 88 of pushing a left side and right lever 84a, 84b.The far-end of left and right lever 84a, 84b can have attached pawl 90 thereon.Pawl 90 can have chamfered surface 92, thus this chamfered surface 92 cooperate with female member 86 when being attached to pommel 52 on the front pillar 20, move inward a left side and right lever 84a, 84b.Pawl 90 can be engaged in female member 86 removedly.

[067] female member 86 can have reverse hat type structure.Chamber 100 can be formed on the central part office of female member 86, and this chamber 100 is become size and is configured to receive the pawl 90 of a left side and right lever 84a, 84b.More specifically, the leading edge 102 in aperture can be become size and is configured to the chamfered surface 92 that when pommel 52 is attached on female member 86 leading edge 102 is matched with the pawl 90 of left and right lever 84a, 84b.In the off-position, pawl 90 is aligned in the leading edge 102 in the aperture of female member 86.Because the angle of chamfered surface 92, when the leading edge 102 in chamfered surface 92 contact apertures and pommel 52 engaged front pillars 20, lever 84 moved inward.When promotion pommel 52 made it to engage front pillar 20, pawl 90 was accommodated in the column part of female member 86.When pawl 90 further is inserted in the aperture of female member 86, thereby finger is received the wheel rim 96 anti-claw stops 90 of the female member 86 of following far-end 98 contacts on surface 88 and further is inserted in the aperture.Approximately this moment, pawl 90 outwards moves and is received in the opening that limits cam face 104.Cam face 104 engaging claws 90 and pommel 52 are locked into front pillar 20.

[068], receives surface 88 pawl 90 is broken away from and the engaging of cam face 104 thereby father and mother can inwardly push finger in order to remove pommel 52 from front pillar 20.At this moment, pommel 52 can be raised out the aperture of female member 86 and pommel 52 and breaks away from and the engaging and being removed from front pillar 20 of front pillar 20.

[069] father and mother can be by pushing that finger is received surface 88 and it is upwards mentioned on the pommel 52 and at first remove pommel 52 from front pillar 20, thereby baby 12 is placed in the baby seat 10.Afterwards, baby 12 is placed in the baby seat 10 and leans to backrest 16 in the position of taking one's seat.In case baby 12 is in the position of taking one's seat, then father and mother can be attached to pommel 52 on the front pillar 20.Distance between the outer perimeter 80 of pommel 52 and two the side support members 18 can be less than the overall diameter of baby's leg 30, thereby owing to baby 12 leg 30 and the interference between the pommel 52 prevents that baby 12 from shifting oneself him or she onto outside the baby seat 10.

[070] Figure 10 and Figure 11 illustrate the 4th embodiment.Particularly, public member 110 can be fixedly secured on the pommel 52 and can be engaged in the female member 114 that is securely fixed on the front pillar 20 (referring to Fig. 2) removedly.Public member 110 can have the outstanding post 116 (referring to Figure 10 and Figure 11) that has hollow cavity of resorption 118 (referring to Figure 11) downwards.Outstanding downwards post 116 can have cylindrical configurations and can limit circular wall and following far-end 120 (referring to Figure 11).Hollow cavity of resorption 118 can limit upper surface 122.Compression spring 124 can be attached on the upper surface 122 of hollow cavity of resorption 118 securely.Outstanding downwards post 116 can have at least one tab 126, and described tab 126 extends from post 116 outward radials.Preferably, post 116 can have two tabs 126 on its subtend side.

[071] female member 114 can have the aperture.Can limit this aperture by cylindrical wall 127 (referring to Figure 11).Cylindrical wall 127 can have the groove 128 (referring to Figure 10) for J type structure.Groove 128 can have from the lock part 134 of the intake section 130 and the crotch that makes progress of leading edge 132 (referring to Figure 11) extension in aperture.The wheel rim 136 of female member 114 can have the otch 138 that aligns with the intake section 130 of groove 128, thereby allows tab 126 to enter in the intake section 130 of J type structure groove 128.The center in aperture can have bossing 140, and this bossing 140 is become size and is configured to receive spring 124.

[078] Figure 17 and Figure 18 show the 6th embodiment that removedly pallet 50 is attached on the baby seat 10.Particularly, pallet 50 can have mushroom head dummy protuberance 170, and this protuberance 170 has the bulbous shaped distal portions 172 on the bottom surface that is attached to pallet 50.As used herein, bulbous shaped can mean circular balloon structure, star, box-like or other enlarged shape.Protuberance 170 can be received in the respective chamber 173 that is formed in the front pillar 20.Mushroom head dummy protuberance 170 can be compressed so as the head dummy protuberance 170 of pester can to slip in the chamber 173 of front pillar 20 and joints thereon.The far-end in chamber 173 or lower surface can have through hole 174, thereby are inserted in the chamber 173 or allow air to spray from chamber 42 when chamber 173 removes or be introduced in the chamber 173 when mushroom head dummy protuberance 170.In this manner, be inserted in the chamber 173 or from the chamber 173 when removing, chamber 173 does not produce any pressure or vacuum when mushroom head dummy protuberance 170.Protuberance 170 has vertical slit 176 alternatively, thereby this vertical slit 176 is extended and extended upward that auxiliary protuberance 170 inserts chambeies 173 and 173 remove protuberance 170 from the chamber from swelling 170 far-end.

[079] more specifically, protuberance 170 can be attached on the bottom surface of pallet 50 or pommel.Protuberance 170 can be become size and be configured to cooperate with the chamber 173 that forms in the front pillar 20 of baby seat 10.By exemplary rather than restrictive mode, protuberance 170 can have slim-lined construction.The distal portions 172 of protuberance 170 can have the bulbous shaped structure.Similarly, the chamber 173 that forms in front pillar 20 can have elongate configuration.The distal portions 178 in chamber 173 can have the bulbous shaped structure of coupling.For example, if bulbous shaped distal portions 172 has box type structure, then the distal portions 178 in chamber 173 also can have box type structure.For pallet 50 is attached on the front pillar 20, the distal portions 172 of protuberance 170 is aligned in the inlet in chamber 173.Plead dish 50 madial walls down and apply internal force radially on the bulbous shaped distal portions 172 of protuberance 170 up to chamber 173.Radially internal force has like this reduced the diameter of bulbous shaped part 172, and bulbous shaped part 172 can slip over the neck 180 in chamber 42 like this.In case bulbous shaped part 172 is passed down through the neck 180 in chamber 42, thereby then the bulbous shaped in bulbous shaped part 172 expansion filling chambeies 173 is constructed part 184.

[080] in order to remove pallet 50 from front pillar 20,173 remove protuberance 170 from the chamber.Particularly, father and mother can upwards promote pallet 50, and this bulbous shaped distal portions 172 that drives protuberance 170 makes progress.The neck 180 in chamber 173 applies the radially internal force that has reduced bulbous shaped part 172 diameters, thereby bulbous shaped part 172 can slip over the neck 180 in chamber 42.In case bulbous shaped part 172 is upward through the neck 180 in chamber 42, then can easily removes protuberance 170 and pallet 50 from the chamber 173 and can break away from and the engaging of front pillar 20.

[081] under normal the use, will swell and 170 in the chamber 42 of formation in front pillar 20, remove thereby baby 12 should produce enough upward forces.Equally, thus father and mother should be able to easily promote pallet 50 breaks away from and the engaging of baby seat 10 pallet 50.

[082] can increase or reduce to be inserted into protuberance 170 in the chamber 173 by surface texturisation, surface treatment mode and the material type that changes protuberance 170 and front pillar 20 and from chamber 173, remove the size of the required power of protuberance 170.

[083] Figure 19 shows the 7th embodiment, and wherein pallet 50 is attached on the baby seat 10 removedly.Particularly, diminished shaft 190 can frictionally be bonded on the corresponding conical cavity 192 that forms in the front pillar 20, thereby pallet 50 is attached on the baby seat 10.Axle 190 can have the diameter that reduces of the distal portions that starts from axle 190 proximal part and end at axle 190.The chamber 192 that forms in front pillar 20 can have and axle 190 identical construction.

[084] in order to make pallet 50 be engaged in baby seat 10, axle 190 is inserted in the chamber 192.The outer surface of axle 190 begins the inner surface of engagement cavity 192.When retainer 194 contacted the upper surface 78 of front pillars 20, axle 190 was fully inserted into.When axle 190 was fully inserted in the chamber 192, axle 190 frictionally was engaged in chamber 192.Because being frictionally engaged between axle 190 and chamber 192, sit in the baby seat 10 baby 12 can not on carry pallet 50.In addition, because axle 190 is engaged in pallet 50 securely and frictionally is engaged in chamber 192, so baby 12 can not promote pallet 50 forward or pull back pallet 50.

[085] thus can remove from baby seat 10 that pallet 50 is auxiliary to remove or make baby 12 to sit in the baby seat 10 baby 12 from baby seat 10.Particularly, thus father and mother can abovely carry pallet 50 overcomes being frictionally engaged between axle 190 and chamber 192.After having overcome being frictionally engaged between axle 190 and the chamber 192, father and mother can remove pallet 50 from baby seat 10.Though Figure 19 shows the pallet 50 that is attached to removedly on the baby seat 10, but also can expect, can pommel be attached on the baby seat 10 removedly via structure shown in Figure 19.

[086] Figure 20 shows the 8th embodiment, wherein pallet 50 via button locking mechanism 200 by attached removedly.Particularly, pallet 50 can be attached on the slender axles 202.Slender axles 202 can have cam face 204, and this cam face 204 can be located in proximate buttons 206.Button 206 can comprise button, spring 208 and fasten 210 with a bolt or latch.By can make door bolt 210 move to the off-position by press button from retracted position (referring to Figure 20).When button release, door bolt 210 can move to retracted position from the off-position.Door bolt 210 can be biased to retracted position.

[087] door bolt 210 can have the hook structure.In slender axles 202 are inserted into the chamber of front pillar 20 and fasten 210 with a bolt or latch when moving on to retracted position, the cam face 204 that door bolt 210 can engage elongate axle 202.When door bolt 210 engage cam surfaces 204, pallet 50 engages front pillar 20 and cannot be removed by baby 12.In order to remove pallet 50 from baby seat 10, father and mother can be by press button, but and this button when preferably being positioned in baby 12 sits in baby seat 10 baby's 12 magnetic touch outside the scope.For example, button can be positioned in the place, middle and lower part of front pillar 20.When pressing press button, door bolt 210 moves to the off-position.Father and mother can upwards mention pallet 50 and axle 202 removed to outside the chamber and with pallet 50 and remove from baby seat 10.Though Figure 20 shows the pallet 50 that is attached to removedly on the baby seat 10, but also can expect, pommel can be via method shown in Figure 20 by attached removedly.Preferably, should expect that button can be positioned at the optional position on the baby seat 10, baby 12 can not touch this button when needing only in sitting in baby seat 10.

[088] Figure 21-29 shows pommel 220 is attached to the 9th embodiment on the front pillar 20 releasedly.In order to make pommel 220 be engaged in front pillar 20, pommel 220 can be molded with public member 222 (referring to Figure 21 a), so that public member 222 is securely attached to pommel 220 (referring to Figure 21 a and Figure 23).Equally, front pillar 20 can be securely attached to female member 224 (referring to Figure 21 a and Figure 23).Can make female member 224 and public member 222 be securely attached to front pillar 20 and pommel 220 via any means known in the field (for example molded, gluing connection etc.).In order to make pommel 220 be engaged in front pillar 20, public member 222 can be inserted in female member 224 (referring to Figure 21 a and Figure 23) and be pushed down.For pommel 220 is broken away from and the engaging of front pillar 20, public member 222 and female member 224 can be manufactured into needs one or two action.By exemplary rather than restrictive one, can remove pommel 220 from front pillar 20 by being rotated counterclockwise pommel 220 (referring to Figure 22 b).Replacedly, public member 222 and female member 224 can be manufactured into needs to push away under the father and mother (referring to Figure 22 a) and be rotated counterclockwise (referring to Figure 22 b) thus pommel 220 breaks away from and the engaging of front pillar 20 pommel 220.

[089] public member 222 can have top 226 and bottom 228, as shown in figure 23.The top 226 of public member 222 can be attached on the pommel 220 securely.By exemplary rather than restrictive one, pommel 220 can be overmolded on the top 226.Top 226 can have a plurality of apertures 230, thereby on pommel 220 is molded in top 226 time, the pommel material is interlocked in the top 226.The basal surface 232 of pommel 220 can have skirt section 234, and this skirt section 234 can have size and be configured to receive front pillar 20, shown in Figure 21-21b.The bottom 228 of public member 222 can have cylindrical configurations (referring to Figure 23).Bottom 228 can comprise opposed inside removable tang 236.Described tang 236 can have size and be configured to be inserted in the female member 224 and can remove from female member 224 with engaging.More specifically, each tang 236 can have the base portion 238 that is attached to top 226.Tang 236 also can limit has the far-end hook 240 that points at least one outer caking 242.On hook 240, neck 244 can limit receiving area 246, and thereby this receiving area 246 is used to receive the inclined-plane projection 248 (Figure 24) of female member 224 makes public member 222 and 224 interlockings of female member.

[090] with reference to Figure 23 and Figure 24, female member 224 can have center port 250, and the bottom 228 of public member 222 can be inserted into by this center port 250.The center port 250 of female member 224 can have cylindrical configurations.Inclined-plane projection 248 with angled upper surface 252 can be formed along the inner surface of center port 250.When pommel 220 was engaged in front pillar 20, inclined-plane projection 248 can be aligned in tang 236.As mentioned above, pommel button surface 232 can have skirt section 234, this skirt section 234 be formed can with front pillar 20 close fitting.If pommel skirt section 234 is misaligned to front pillar 20 angularly, then tang 236 is misaligned to inclined-plane projection 248.In addition, can interfere the consideration of front pillar 20 based on the skirt section 234 of pommel 220, pommel 220 may not can be engaged in front pillar 20.When the skirt section 234 of pommel 220 was aligned in front pillar 20, tang 236 can be aligned in inclined-plane projection 248.

[091] in order to make pommel 220 be engaged in front pillar 20, the bottom 228 of public member 222 is inserted in the aperture 250 of female member 226.(referring to Figure 23).The skirt section 234 of pommel 220 is aligned in front pillar 20, thereby makes tang 236 be aligned in inclined-plane projection 248.Push away pommel 220 afterwards down, thereby the hook 240 of tang 236 (referring to Figure 23) or far-end will contact the chamfered surface 252 (referring to Figure 24) of inclined-plane projection 248.Along with continuing to promote pommel 220 downwards, chamfered surface 252 moves inward tang 236, thereby with hook 240 or lump and 242 be moved out to outside the path of inclined-plane projection 248.Before hook 240 engagement ramp projections 248, the basal surface 232 of pommel 220 can contact the upper surface 78 of front pillar 20.In order to make hook 240 engagement ramp projections 248, preferably, thereby father and mother or user provide the downward thrust of increase or downward force to make hook 240 be engaged in inclined-plane projection 248.When pommel 220 was engaged in front pillar 20, inclined-plane projection 248 can be positioned in the neck 244 of tang 236.Preferably, the basal surface 256 (referring to Figure 24) of the upper surface 254 (referring to Figure 23) of hook 240 and inclined-plane projection 248 has interlock fit surface or interlocking structure.For example, the upper surface 254 of hook 240 can be parallel to the transverse plane of the central axis 258 (referring to Figure 23) of public member 222.Equally, the basal surface 256 of inclined-plane projection 248 can be parallel to the transverse plane of the central axis 260 (referring to Figure 23) of female member 224.In this manner, even upwards spur pommel 220,, inclined-plane projection 248 discharges pommel 220 from front pillar 20 thereby can not moving inward tang 236.More specifically, the basal surface 256 of the upper surface 254 of hook 240 and inclined-plane projection 248 can have interlocking structure upwards as shown in figure 25.Like this, when hook 240 was matched with inclined-plane projection 248, surface 254,256 separately was with interlocking.Thereby being applied to any upward force on the pommel 220 will further drive hook 240 and enter into the joints of guaranteeing in the inclined-plane projection 248 between pommel 220 and the front pillar 20.When pommel 220 was engaged on the front pillar 20, inclined-plane projection 248 can be located in the neck 244 of tang 236.

[092] by relative front pillar 20 rotation pommels 220 (for example rotating 45 degree), can remove pommel 220 from front pillar 20, shown in Figure 22 b.As mentioned above, the skirt section 234 of pommel 220 is configured in front pillar 20 substantially.Like this, any rotation of pommel 220 can be resisted in the skirt section 234 of pommel 220.Yet, can use cardinal principle flexibility or elastomeric material to make or make pommel 220.Like this, under enough revolving forces, skirt section 234 can flexing and pommel 220 front pillar 20 and rotating relatively.When relative front pillar 20 rotated pommels 220, inclined-plane projection 248 (referring to Figure 24) was slided or is rotated the slotted section 262 (referring to Figure 23) that leaves tang 236 (that is, neck 244) (referring to Figure 23) and enter the bottom 228 of public member 222.Thereby can make inclined-plane projection 248 slide through the slotted section 262 of the bottom 228 of public member 222 by above saddle 220 in advance.At this moment pommel 220 disengagings engage with front pillar 20.Can realize such being disengaged by the action of reversing pommel 220.

[093] replacedly, can via two actions (be downward force (referring to Figure 22 a) and twisting action (referring to Figure 22 b)) remove pommel 220 from front pillar 20.For example, tang 236 also can have antelabium 264 (referring to Figure 23 a), this antelabium 264 links hook 240 and necks 244, shown in Figure 23 a.If only rotate pommel 220 then antelabium 264 will be interfered inclined-plane projection 248, thereby prevent that inclined-plane projection 248 is aligned in the slotted section 262 of the bottom 228 of public member 222.In order to make inclined-plane projection 248 be aligned in slotted section 262, the user must be pressed in downwards on the pommel 220, thus the antelabium 264 of inclined-plane projection 248 inswept tang 236 shown in the arrow 266 of Figure 23 a.At this moment, thus user or father and mother can rotate pommel 220 makes inclined-plane projection 248 be aligned in slotted section 262.Lift pommel 220, inclined-plane projection 248 slide through slotted section 262 and this moment pommel 220 break away from and the engaging of front pillar 20.

[094] as mentioned above, can make female member 224 be engaged in front pillar 20 securely via other method gluing, molded or well known in the art.A kind of non-method well known in the art will be described below.By exemplary rather than restrictive one, female member 224 can be selectively engaged in retaining ring 268 (referring to Figure 26).Retaining ring 268 can be molded in the front pillar 20 and aperture 270 can form and connects front pillar 20 and extend between the upper surface 78 of front pillar 20 and retaining ring 268, as shown in figure 27.Female member 224 can have a plurality of flanges 272, as shown in figure 28.These flanges 272 can be inserted in the aperture 270 of front pillar 20.The far-end 274 of flange 272 can have the notch 276 that forms within it, as shown in figure 28.Notch 276 is horizontal alignment each other.
