Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a high chair according to the preamble of the first item of the patent application. [Prior Art] A high chair should be relatively high to allow the child to sit at a height slightly below the height of a table/table and should also have a high degree of safety ', among other things, prevent falling over the floor At a wide distance from the point, a large space. Thus, the ideal configuration first retracts the storage position, and the effective locking of the position in the extended position of the second 'extended user position is of course' ideal to be able to sell and separate a portion of the unassembled leg. The legs of the one-yuan chair are mounted by attaching a separate socket. Typically, the back foot of the chair is in the area of the seat of the early element, which means the maximum size of the package. . Therefore, the leg is preferably supported in the sense that the high chair requires a pair of legs of the opposite high chair to be pivoted near the position of the other pair of legs, and therebetween. It is ensured that the foldable chair legs are ideally 'the lock can be disengaged. The footrest chair is in the form of a minimum package. The chair to which the chair foot can be attached is connected to the chair unit on the chair unit, and the chair leg is relatively long and bounded. SUMMARY OF THE INVENTION 5 Xuannan foot chair Therefore, it is an object of the present invention to provide a foot chair 4 201105273 structure that allows the length of the foot of the high chair to be reduced, the same length and the same design for all the legs of the chair . Package:: Allows the size of the unit's package and the unassembled legs to be: Therefore, the maximum size of the package is determined by the chair unit, which is determined by the length of the foot. In addition, is it to promote the attachment of chair chat? A further object, rather than a chair lock, is to provide a center for the legs of the folding pair that must be operated to separate the positional safety. The purpose of the W-facing legs is to achieve a high-step-by-step design that provides a high chair for one or several purposes. m - or a plurality of these objects are wholly or partially in accordance with the invention. The invention is defined in the separate item of the scope of the accompanying claims. Embodiments of the invention are sub-claims that define the scope of the patent application. Accordingly, the present invention relates to a sturdy chair unit that includes a seat, a back frame that is securely attached to the seat, and is firmly attached a distance from the seat to the seat, the foot being placed at a distance below the height of the seat, wherein the chair unit is carried on a pair of front and rear legs and a pair of rear legs, wherein the pair of legs are mutually Folding between a support position and a storage position, the pair of legs extend from each other; and in the storage position, the pair of legs are retracted toward each other. The foot of the front leg is worn through the chair unit in the pedal area. The foot of the rear leg is mounted on a lower portion of the pole 201105273, and the inner portion of the chair unit is rotatably rotated in a transitional region between the back frame for pivoting movement of the material-horizontal axis The length of the footrest # for surrounding the footrest is adapted to minimize the length of the foot of the chair, in the actual embodiment the length of = substantially corresponds to the "foot"

[Embodiment] Figs. 1 to 3 show a chair. The chair comprises a chair unit 2 made of injection molded plastic. The chair unit includes a back frame 3, a seat 4' and a footrest 5'. The footrest 5 is integrally attached to the front edge region of the seat 4 via a substantially vertical attachment wall portion 6. A safety device (7) package 3 is centrally located 1 1 , which is slidable in a vertical symmetry plane of the high chair and is connected at the lower end 丨 2 to the transition between the seat 4 and the wall 6 Area. The upper end portion of the cylinder 11 is provided with a table portion 13 having a concave side facing the back frame 3. 11 is stopped at a blocking mechanism not shown in the drawings so that the upright position of the cylinder is possible. In a step-by-step manner, the chair unit 2 includes a link 15 that engages an upper portion of the journal that engages a 16-circumferential-horizontal axis that is positioned adjacent the transition between the back frame 3 and the seat 4 'display link 15 The lower end of the lower end is at the same height as the footrest 5 at the end position. The lower side edges of the chair unit are reopened from each other in the - downward direction. The connecting rod 15 has a side edge which is also opened again in the downward direction. The lower side edge of the chair unit in the footrest $ area and the side edge of the link 15 at the lower end of the link 15 have the form of a receiving sleeve or a socket... 'It shows a rounded foot 21, a rounded foot: The risk of the foot 20 hooking onto any object on the floor surface/floor includes the risk of the south foot chair tipping over. The leg 20 can have a blocking spring that snaps into a corresponding recess of the individual seat door to ensure a proper orientation of the foot 21. The leg 2 〇 has legs 21 which are preferably similar to each other and of equal length. The four legs 20 on the high chair meet up to a point on the seat 4. From Fig. 1, it can be inferred that a cover #3〇 { is mounted on the bottom side of the chair unit in the area of the wall portion 6 and the footrest 5 for spacing (screen) a space 31 therebetween. A detachable locking device 7 is shown attached between the lower end portion of the link 15 and the cover member 3A attached to the chair unit 2, as shown in more detail in Figures 4 and 5. Accordingly, it can be seen that the cover member 3 has a substantially vertical wall 32 having an opening 201105273 33 for a guide track 4'. The guide track is passed through - a bearing 41 having a substantially horizontal axis The lower end portion of the journal joint link 15 ... the lock unit 44 is open, and the bearing 41 having a substantially horizontal axis is journaled to engage the lower jaw of the link ^. A locking unit 44 is journaled to the guide rail 4, and the journal engages the axis of the surrounding bearing 41. The free end 47 that locks early is extended through the opening 33 of the wall 32 when the pair of rear legs is extended. A spring 46 is shown placed between the guide lane 4 and the locking unit 44. Alternatively, the locking unit itself flexibly bends the wrap 43 displayed on the guide track 4 to achieve the function of the displayed magazine 46. It is further shown that the locking unit has a mating surface (four) coffee (10) coffee (four) 45 in a stepped form, when the rear leg pair extends _, in the extended position of the locking unit, through cooperation with the upper edge portion of the opening 33, to avoid The back of the back of the chair is - retracted or folded. The abutment surface 45 can pass through the opening 33 by rotating the locking unit 44 toward the guiding track 40. The locking unit has a -tip 49 that snaps into the area of the wall 32 behind the opening 33. The cover member has a generally horizontal bottom unit 37' having a guide cam 38 for the lower end of the tip end. By manually applying pressure downwardly against the locking unit 44 in one direction, the locking unit 44 will approach the guiding track 4 so that the phase of the locking unit: the surface 45 along with the guiding track 4 〇 can pass through the opening Moving away, so during the pushing into the space 31, the lower edge of the guiding track 4〇 and the upper side of the locking unit are slidable against the opening 33 below the individual upper edge 6 for the connecting rod In the vicinity of the retracted position of 15, the tip 49 will slide onto the guiding cam 38 and then quickly enter a recess 8 201105273;:, 1 turn 5: wide. The apparent 'slope' has a side surface 54 against which the end surface of the end face abuts. These surfaces are inclined in the opposite direction and the guide rails are elastically bent to fit the guide. Α, s a user wants to fold the rear link 15 together with the squatting foot 20 toward the display right sill, 抒) after the end position of the extended position of Figure 1, the user must apply a relatively large yf seven fields &> 4, the force is in the longitudinal direction of the guiding track 40, so that the tip 49 is particularly free from the recess. Of course, the user can suddenly send the motion without r μ, without stopping the applied force, but the acceleration link 15 is together with the leg 2 and the guide rail 4 so that the momentum becomes sufficient. To surely overcome the friction between the locking unit 44 and the guide rail 4 ,, respectively, - the upper and lower edges of the 1 and the contact surface 45 of the locking unit surely passes through the opening 33 And is biased to the blocking position under the influence of the spring 46. The magazine bias lock unit 44 of course also provides a child-safe (ChildPr〇〇f) lock that avoids the unintentional entry of the link 15 with the rear leg pair 2〇 toward the retracted position, here In the embodiment, since the spring force is strong, it is necessary to use both hands against the guiding rail to push the locking unit. Each of the legs 20 can have a groove or a protrusion which is respectively associated with the socket 17 Corresponding projections or grooves cooperate (not shown) to ensure proper orientation of the individual legs relative to the stem 17, so that the individual feet 21 achieve a predetermined orientation relative to the high chair. Figures 6 and 7a show several prior embodiments in which the legs are locked in a fixed position in the individual sockets to achieve proper alignment of the individual feet relative to a support. In Fig. 6, the link 丨 5 shows a socket 9 201105273 1 7 for individual feet. The individual seat 17 has an opening j 73 in a predetermined position. This opening can be designed with chamfered edges to aid in the entry of the fingers. When a leg rest is positively placed in its socket, a blocking mechanism 172 limits the leg to the opening, as will be described in more detail below with reference to Figures 7a, 7b. In Fig. 7a, the upper end having a leg 2 is shown with a blocking mechanism 1 73'. The blocking mechanism is configured to resiliently project through an opening 173 provided for this purpose. The blocking mechanism 172 is preferably part of the curved wire 174 in the presently illustrated embodiment, the wire! The 74 series is U-shaped and is more compactly shown in Fig. 7b, having a crotch portion 175 for abutting the inner side of the individual leg, diametrically opposite the X opening 173. The 忒 bending blocking mechanism 172 is preferably designed such that the wire extending in the longitudinal direction of the leg 20 is disposed at an angle to the length of the leg, so that it has a small height. The end is placed close to the upper end of the chair. With this structure, a large number of chair legs are attached to the chair unit. It may be configured to provide a guide for the correct orientation of the chair foot 2 with respect to the receiving socket, for example in the form of a recess in the edge of the socket, such that the blocking mechanism It is entered into the trench and thus the correct entry into the locking opening in the stem.
