Description

High chair with folding leg {HIGH CHAIR WITH FOLDING LEGS}

The present invention relates to a high chair according to the preamble of claim 1.

The high chair should be relatively high to allow the child to sit at a height slightly below the height of the table, and above all, must also have high safety against tipping over. Therefore, the leg is properly oriented to be supported on the floor at widely spaced points, which means that the high chair requires a relatively large space. Therefore, it is desirable to position the high pair of leg pairs to pivot between the first retracted receiving position and the second extended user position, near the position with respect to the other leg pair. It is of course desirable to be able to ensure effective locking of the foldable leg in the extended position, and the lock can be detached. Furthermore, it is desirable to be able to distribute and sell high chairs in the form of a minimized unit finished product comprising a chair device that can be partially leg attached, a leg that is not partially assembled. The legs of the chair are installed by attaching them securely to their tips for each socket with the chair device.

It is an object of the present invention to provide a locking mechanism for a high chair, in addition to the secure locking of the leg pair in the extended position, the locking mechanism takes a fully extended position and a locked position with high stability when the leg pair is extended from the retracted position. Allow it.

A further object is to provide a locking mechanism that is easily detached to allow the pair of legs to be returned to their retracted position.

One or several of these objects are achieved in whole or in part with the present invention.

The invention is defined in the appended claims.

Embodiments of the invention are defined in the appended dependent claims.

Thus, the present invention provides a locking mechanism that provides automatic locking of a leg pair and a high chair with a foldable leg pair when the leg pair moves to an extended tip position, where the locking mechanism provides a leg for returning the leg pair to the retracted position. It has control means to allow separation of the pair.

Furthermore, a blocking device is provided, which is arranged to maintain the foldable leg pair in the retracted position up to a predetermined limit of torque applied to the leg pair with the center of the pivot bearing. When the user torques the leg pair above this limit, the blocking device (and the user's arm) is arranged to rapidly release the leg pair such that there is a momentum present up to the locked tip position of the leg pair by the locking device.

The high chair may comprise a rigid chair device, the chair device comprising a seat, a backrest securely attached to the seat and a footrest securely attached to the seat, the footrest being positioned at a distance below the height of the seat and The chair device has front and rear leg pairs, which leg pairs can fold together between a support position in which the leg pair extends from each other and a receiving position in which the leg pair is retracted towards each other. The front leg pair can be permanently attached to the chair device in the region of the footrest. The rear leg pair can be mounted to the bottom of the link, and the top of the link is pivotally rotated in the chair device in the transition area between the seat and the back for a pivoting movement about the horizontal axis. The length of the link can be appropriately adjusted to enable the use of equally and equally long legs mutually against the high chair. This minimizes the length of the leg, which in a practical embodiment the length of the leg is substantially equivalent to the maximum dimension of the chair device, for example the length of the unit finished product in the symmetry plane of the chair device determines the length of the unit finished product substantially and This means that the chair device has a capacity within the size of the carton adapted to the chair device, for example in the form of a parallelepiped.

The high chair according to the invention, like its embodiment, will be described in connection with the embodiment of the invention described in the accompanying drawings:
1 shows a side view of a high chair according to the invention;
2 shows a rear view of a high chair according to the invention;
3 shows a front view of a high chair according to the invention;
4 shows an enlarged view of a partial cross section of the locking mechanism for the rear leg pair of the high chair in the extended position; And
FIG. 5 shows a view corresponding to FIG. 4 with a pair of legs at the rear in the retracted position. FIG.

1 to 3 show a chair device 1, which comprises a chair device 2 made of injection molded plastic, which comprises a backrest 3, a seat 4, and a footrest 5. This footrest is integrally attached to the front edge region of the sheet 4 via a substantially vertical attachment wall 6. The safety device 10 comprises a central post 11, which is pivotal in the vertical symmetry plane of the high chair and has a lower end journaled 12 in the transition area between the seat 4 and the wall 6. At the upper end of the post 11, a table 13 having a concave surface facing the backrest 3 is arranged.

The blocking means not shown in the figure enables the fixing of the post 11 in an upright position.

Further shown is a chair device 1 comprising a link 15, the upper part of which is journaled at 16 about a horizontal axis, the horizontal axis being between the backrest 3 and the seat 4. It is located in the vicinity of the transition area. The lower tip of the link 15 is shown in an extended tip position at approximately the same height as the footrest 5. The lower side edges of the chair device diverge from each other in the downward direction. The link 15 also has side edges that split in the downward direction. The side edge of the link 15 at the lower tip of the link 15 and the lower side edge of the chair device in the area of the footrest 5 have the form of an accommodating socket or sleeve, which socket or sleeve is a separate chair leg ( 20), this leg 20 is shown having a rounded pit 21, which limits the risk of the high chair falling over because the leg 20 is caught by an object on the ground / floor do.

The leg 20 can have a locking spring, which engages a corresponding recess in each socket 17 to ensure correct orientation of the pit 21. The legs 20 with the pit 21 are preferably equally and equally long with each other. The four legs 20 of the high chair concentrate upwards towards the point on the seat 4.

From FIG. 1, it can be concluded that the cover 30 is mounted below the chair device in the region of the wall and the scaffold to block the space 31 between the region of the wall 6 and the scaffold 5. The detachable locking device 7 is shown to be attached between the lower end of the link 15 and the cover 30 attached to the chair device 2, as shown in more detail in FIGS. 4 and 5. Thus, a cover 30 with a generally vertical wall 32 having an opening 33 to the guide rail 40 can be shown, which guide bearing bearing 41 having a substantially horizontal axis. Through the lower end of the link 15. The locking member 44 is journaled to the bottom of the link 15 via a bearing 41 with a substantially horizontal axis. The locking member 44 is journaled to a guide rail 40 journaled about the axis of the bearing 41, for example. The free end 47 of the locking member extends through the opening 33 of the wall 32 when the rear leg pair extends. The spring 46 is shown to be positioned between the guide rail 40 and the locking member 44. Instead, the locking member itself can be flexibly elastically bent around the illustrated support 43 on the guide rail 40, thereby obtaining the function of the illustrated spring 46. The locking member is further shown to have a stepped contact face 45, wherein the stepped shape in the extended position of the locking member cooperates with the upper edge position of the opening 33 when the rear leg pair extends. To prevent contraction or folding of the rear leg pair. By contacting the locking member 44 toward the guide rail 40, the abutment face 45 can be passed through the opening 33.

The locking member has a tip 49, which meshes behind the wall 32 in the region below the opening 33. The cover has a generally horizontal lower device 37 with a guide cam 38 for the lower tip of the tip 49.

The pressure is applied manually in the downward direction against the locking member 44 so that the abutting surface 45 of the locking member together with the guide rail 40 can be displaced through the opening 33. 44 approaches the guide rail 40, so that the lower edge of the guide rail 40 and the upper side of the locking member 41 are pushed into the opening 33 under each upper edge while pushing into the space 31. You can move against it. As shown in FIG. 5, in the vicinity of the retracted position relative to the link 15, the tip 49 will move on the guide cam 38 and snap into the next recess 51. A ramp with a steep cross section 39 is apparent, which faces the side 54 of the tip facing and facing the cross section. This face is inclined with respect to the longitudinal direction of the guide rail, and furthermore, the guide rail 40 is arranged to bend elastically. When the user wants to straighten the rear link 15 with the rear leg 20 towards the extended tip position shown in FIG. 1, the user guides the tip 49 to suddenly exit the recess 51. A relatively large force must be applied in the longitudinal direction of the rail 40. Of course, the user does not stop the applied force, but the momentum is sufficient to ensure that the friction force between the guide rail 40 and the locking member 44 is overcome, respectively, against the upper and lower edges of the opening 33, respectively. The user moves the link 15 together with the guide rail 40 and the leg 20 so that the abutting surface 45 of the member passes through the opening 33 and deflects to the blocking position under the influence of the spring 46. Can be accelerated.

The spring biased locking member 44 also naturally provides a safe lock for children that prevents inadvertent folding of the rear leg pair 20 and the link 15 towards the retracted position.
