Abstract
The utility model relates to a rotatable footrest frame capable of being connected with other chairs, which overcomes the shortcoming that a footrest frame in a draw-pull structure in the prior art is unsuitable for modification and use in an existing seat and comprises a footrest plate and a framework. The framework used for supporting and fixing the footrest plate is mutually hinged with a base frame and mutually hinged with the footrest plate. The framework can rotate around the end by the aid of connection of the framework with the footrest plate, the footrest frame with the method brings convenience to modification of a traditional seat, can simultaneously change the angle and the height of the footrest plate, is more comfortable in use, and can adapt to people with different heights for use.
Description
Technical field
The utility model relates to a kind of leg rest frame, especially a kind of rotatable and leg rest frame that can be connected with other chairs.
Background technology
Present chair does not generally have corresponding leg rest frame, have only some specific chairs just to be equipped with the leg rest frame, the long people of leg can be placed on pin the effect that support is played on ground, can also alleviate simultaneously stressed to knee, but for the people of short legs such as child, just not too adapt to higher seat, shank is being taken for a long time, influence to knee is also bigger, particularly child accomplishes not have on the nursery chair of leg rest frame, itself sit just uncomfortablely, and child is also active, if there is not the leg rest frame to support to him, child drops easily.
Patent Office of the People's Republic of China has announced a CN201076221Y patent on June 25th, 2008, name is called Rocking chair frame, this Rocking chair frame comprises back rest, mounting, ceiling frame and leg rest frame, back rest, mounting, ceiling frame and leg rest frame constitute by pipe fitting or rod member, one space is arranged in the mounting, leg rest frame and mounting are slidingly connected and are positioned at this space, the leg rest frame is connected to form by two L type bend pipes, a sleeve pipe and supporting steel pipes, and an end of two L type bend pipes all is positioned at the chute that is fixed on the mounting.But this leg rest frame is a drawing structure, pulls out during use, not time spent withdrawal, not too convenient repacking again in existing seats such as nursery chair.
Summary of the invention
The utility model has solved the leg rest frame that uses in the prior art and has been drawing structure, is not suitable for the shortcoming that repacking is used on conventional seat, and a kind of leg rest frame that adopts rotary structure conveniently to reequip on existing seat is provided.
The utility model has also solved existing leg rest frame and has belonged to the shortcoming that drawing structure can not be regulated up and down height, provides a kind of and adopts rotary structure and can regulate the leg rest frame of height up and down.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of leg rest frame, comprise toe board, and the leg rest frame also comprises and is used for the skeleton of support fixation toe board on the Connection Block frame, and skeleton is hinged with a seat frame, and skeleton and toe board are hinged.For the height with child is complementary, general nursery chair is all than higher, when child sits on the chair, because shank is shorter, can not directly support to ground, after using the leg rest frame, child's pin steps down on the toe board, can play the effect of support, adopting skeleton to support toe board can weight reduction, convenient carrying is not interfered original nursery chair yet, and the upper end of skeleton is hinged with the seat frame, make skeleton to rotate, thereby drive the toe board rotation, like this can also the motion shank when using the leg rest frame, long-time sitting posture can not cause fatigue yet; When installing if present frame or handrail position be provided with one with skeleton on hinged parts.
As preferably, skeleton takes the shape of the letter U, and is connected with toe board at the bottom of the U-shaped, and two ends of skeleton are hinged with the seat frame.Skeleton takes the shape of the letter U and is structure as a whole, and guarantees the stability of skeleton, can left and right sides deflection, and the position of toe board makes the active force that produces all be delivered on the skeleton, when especially pin steps down on the toe board, can bear bigger power; The upper end of skeleton is hinged, makes leg rest frame integral body to overturn, thereby can change the position of leg rest frame, can not interfere.
As preferably, the back side of toe board is provided with holder, and the surface of holder is provided with groove, and skeleton snaps onto groove and buckles with base by screw and fixes.This mode connects skeleton and toe board, and feasible connection is more stable, can produce relative rotation between toe board and the skeleton simultaneously, but need certain power again when rotating, thereby guarantee that toe board can not rotate automatically, and the assurance toe board is stablized.
As preferably, skeleton is formed by two L shaped support body positioned opposite, and the end of the minor face of L shaped support body and the both sides of toe board are hinged.The end of L shaped minor face and the side of toe board are hinged, and the end connects the mode can adopt joint and interface, and this scheme is divided into two sections with skeleton can reduce the skeleton consumption, connect also more conveniently, and joint is inserted into interface just.
As preferably, two upper ends of skeleton are connected with rotary body respectively, and rotary body divides two parts to comprise overcoat and interior axle, and interior axle fixes with a seat frame, and the overcoat rotary type is nested with outside interior axle.Overcoat and interior axle can rotate mutually, and overcoat links to each other with skeleton, and interior axle is connected on the seat, and the sunshade skeleton is realized by the rotation of overcoat and interior axle.
As preferably, the upper position of skeleton is a connected structure, and what connect rotary body be extension tube attached, the connection toe board be inner connecting tube, extension tube attached is nested with outside inner connecting tube and by keeper and connects.Connected structure can be so that skeleton can move up and down, thereby change the height of toe board, use to adapt to the long people of different legs, when changing the length of skeleton, fix by keeper, keeper can be the cylinder that is connected with elastic component, outer setting in extension tube attached has circular hole, skeleton moves to correct position, and keeper ejects from circular hole, thereby finishes fixing.
As preferably, the front of toe board is provided with sagging sole seal or tread plate or antiskid particles.This structure can guarantee the frictional resistance in toe board front, prevents to skid.
The beneficial effects of the utility model are: connect toe board by skeleton, skeleton can rotate around the end, and this mode makes things convenient for the traditional Chinese chair repacking, can change the angle and the height of toe board simultaneously, uses pleasantly, can adapt to people's use of different heights.
