Description

A kind of crutch and the dual-purpose telescopic folding lever apparatus of Simple seat
Technical field
The present invention relates to a kind of assist, and in particular to a kind of crutch and the dual-purpose telescopic folding bar of Simple seat Device.
Background technology
The elderly walks for convenience, and people design crutch using as a support, but the elderly walk outside one section away from From rear if it is desired to when looking for the place to take a load off one's feet, can not often achieve one's goal because of the limitation of various factors, but if carry simultaneously Crutch and stool are then inconvenient, and are a no small burden for the user.Chinese patent CN203748790U is public A kind of apparatus for having crutch, stool function concurrently, including crutch portion and stool portion are opened, the crutch portion includes handle portion and setting Supporting part under handle portion;The stool portion include above stool surface and the support member that is arranged under stool surface, the stool surface and The connecting portion intersected for the supporting part is provided with separately below, but needs to carry out excessive operation during the instrumentation, and due to There is provided stool surface, volume ratio is larger, very not readily portable and storage.
The content of the invention
The purpose of the present invention is exactly to provide a kind of crutch and the dual-purpose flexible folding of Simple seat to solve the above problems Folded lever apparatus.
The purpose of the present invention is achieved through the following technical solutions:
A kind of crutch and the dual-purpose telescopic folding lever apparatus of Simple seat, including matrix bar and it is symmetricly set in matrix bar The telescopic folding mechanism at two ends, described telescopic folding mechanism is arranged inside matrix bar and moved along its axis, and described stretches Contracting fold mechanism includes outer layer loop bar, internal layer loop bar and multigroup folding support bar component, and described internal layer loop bar is set Inside outer layer loop bar and move along its axis, described support bar component is arranged on outside outer layer loop bar and edge by connector It is moved axially, and described support bar component includes first support bar and second support bar.
As crutch in use, described outer layer loop bar stretches out matrix bar, described internal layer loop bar stretches out outer layer loop bar, institute The support bar component stated is close on outer layer loop bar and internal layer loop bar, and the telescopic folding lever apparatus is in shaft-like;
As Simple seat in use, in described internal layer loop bar retraction outer layer loop bar, described outer layer loop bar stretches out base Body rod, the first support bar of the support bar component is in horizontality, and second support bar is in heeling condition, the telescopic folding Lever apparatus is in seat stool shape.
Further, described matrix bar is cylindrical shape, and its upper and lower side is provided with bell-mouthed pipe, matrix bar bosom Position is provided with the separated interlayer of both sides telescopic folding mechanism.
Further, the outer end of described internal layer loop bar is provided with end cap, and the end face can rely on similar button with connector Cooperation and fix.
Further, described first support bar and second support bar are rectangular slab, first support bar and the second support It is hinged between bar, the other end is by being installed on connector, and described first support bar is longer than second support bar.
Further, described support bar component is made up of 3-4 groups first support bar and second support bar, is distributed in outer layer Loop bar surrounding.
Further, described matrix bar, outer layer loop bar and internal layer loop bar are provided with pin hole, described pin hole Provided with for fixed latch.
Further, described outer layer loop bar and internal layer loop bar are square tube.
When specifically used, in initial shape or receiving state, all above-mentioned parts are all retracted in the matrix bar of outside, support bar Component shrinks, and fits on the outer wall of inside and outside parts casing pipe, and two connectors are connected, internal layer loop bar by additional latch realize with The fixation of matrix bar.There are two outside the relative rotation around axle center, articulated elements symmetrically to prevent internal rod from being produced with matrix bar Chute inside steady pin, with matrix bar, which cooperates, fixes angle, and the interlayer in matrix bar most centre position is by the bar of both sides Part is separated, it is to avoid the position conflict produced by misoperation.
As crutch in use, all latches are removed, internal Liang Tao telescopic foldings mechanism is stretched to axially outward Extreme position, inner layer sleeve and outer layer sleeve and matrix bar are in linear relative movement, and internal layer loop bar reaches capacity position, treats outer layer Loop bar also reach capacity position when, latch is inserted in corresponding pin hole to reach fixation, then by support bar component edge Axis direction is outwards pulled, until the connector close to end face is mutually fixed with end cap by the cooperation of similar button, now Two support bars are in open shape, each parallel to axis direction.
As seat in use, being operated on the basis of crutch shape, first by internal layer loop bar exert a force axially inward with It is entirely retracted among outer layer loop bar, the end cap being now connected on internal layer loop bar is stuck in outer layer jacket under inside active force The end face of bar, then outer layer loop bar is inwardly contracted at seat, the support bar close to end face is in horizontality, now outer layer jacket The pin hole of another position, this pin hole is inserted to ensure it as seat shape by latch on the pin hole correspondence matrix bar of bar State, now another connector is in the end position of matrix bar, the end of the support bar being hinged with this connector and matrix bar Edge is parallel and is engaged, and the power that user sits on the seat is substantially vertical downwards, then support force is from two aspects: Internal layer loop bar and latch are in contact the support force straight up of generation, the edge of the generation that is engaged of support bar and end edge The support force in edge internal tangent direction.
The present invention provides a kind of crutch and the dual-purpose telescopic folding of Simple seat for the trip and outdoor rest of the elderly Lever apparatus, the compact simplicity in contraction state, it is easy to which pickup is carried, mitigate and carry burden;Small volume during storage, is not take up excessive Its crutch form can be opened auxiliary walking, it is necessary to its seat form can be opened into auxiliary during rest by space, user when walking Rest is helped, the present apparatus is simple in construction, and manufacturing cost is low, durable, and service life is long.
