Description

a seat trolley

technical field

The invention relates to a trolley, in particular to a seat trolley with simple structure and multi-purpose, which can be combined with ordinary chairs, deck chairs, baby seats, cradles and child seats.

Background technique

Existing trolleys are various, but they have always existed independently, and multi-purpose trolleys that can carry people such as combined chairs have never been designed;

The application number is CN2012104659729, which discloses a multi-purpose trolley, including: a bracket and a pallet are provided on the shaft of the two wheels, a handle that can also be inserted into the vertical branch is arranged in the horizontal branch of the bracket, and the support of the support A spring is arranged between the bracket and the bracket, the bottom of the bracket has a pedal and a supporting wheel, and the other end of the pedal has a guide rod with a stopper set in the guide groove of the guide plate with a stopper on the shaft; the application number is CN2014102245380, which discloses a A multi-purpose trolley capable of realizing functional interchange between tables and trolleys, including a panel, a U-shaped push rod and universal wheels. If only one U-shaped structure hand push rod is installed, it will become a standard flat trolley; if two U-shaped structure hand push rods are installed, it will become a double push rod flat trolley; turn the double push rod flat trolley upside down, and unscrew the universal wheel becomes a flat table;

They serve multiple purposes, but are all designed to carry cargo, not people;

Simplifying the structure and amplifying the efficacy are part of invention and innovation;

With the increasing number of elderly people in society, how to let the elderly spend a happy and happy old age is something that each of us must do. There are many types of wheelchairs, but the elderly are a bit old-fashioned. They think that wheelchairs are The patient sits, and people see him as if he has become a patient or is paralyzed, so as long as he can move a little, he is determined not to take a wheelchair, but he likes to sit on the same chair or recliner; for a person who doesn’t like wheelchairs It is very difficult for the elderly to buy a wheelchair, and the placement takes up space, and the folding wheelchair is not comfortable;

How can one cart be multi-purpose, economical, environmentally friendly and make the elderly like it? After long-term understanding and observation of the elderly at home, as well as consulting and searching a large amount of information, I finally designed a seat trolley with a simple and practical structure, a wide range of uses, and easy assembly.

Contents of the invention

The technical problem to be solved by the present invention is to provide a seat trolley with simple and practical structure, convenient use and combination.

A seat trolley, comprising a trolley and a chair, characterized in that the trolley is a combined trolley, the left and right sides of the combined trolley are each provided with a base frame, and the rear end of the base frame is provided with a rear wheel, The front end of the pedestal is provided with a universal wheel, and the inner sides of the lower ends of the pedestal on both sides are respectively fixed with combination strips, and a plurality of tapered combination holes with upper and lower sides are arranged in the described combination strips.

The upper and lower inside of the push handle combined pipe on both sides are respectively fixed with assemblies, and the assembly is provided with Combination hole, a rear combination plate is arranged between the rear ends of the pedestals on both sides, the upper and lower ends of the rear combination plate are respectively fixed with combination plugs matching the combination holes, and the hand-push combination tubes described on both sides Each is provided with a fixing piece, and each of the braking devices is provided between the base frame on both sides and the rear wheel.

It is characterized in that the trolley is a folding trolley, the rear end of the folding trolley is provided with rear wheels, the front end of the folding trolley is provided with universal wheels, and the left and right sides of the folding trolley are respectively provided with The base strip, the rear end of the folding trolley is fixed with a rear bottom plate, the front end of the rear bottom plate is connected to the front folding bottom plate, and the left and right sides of the rear bottom plate are respectively provided with a plurality of fixing holes, and the left and right or front and rear fixed holes There are fixing belts movable between the holes, folding hand push handles are pivotally connected to the left and right sides of the rear end of the folding trolley, and a plurality of limit adjustment holes are respectively arranged on the left and right sides of the rear end of the folding trolley. A limit adjustment member is arranged between the folding hand push handle and the limit adjustment hole, and a brake device is respectively arranged between the left and right sides of the foldable trolley and the rear wheel.

It is characterized in that the rear wheel of the trolley is a pneumatic tire, the diameter of the rear wheel is larger than that of the universal wheel, and the trolley is provided with a chair fixing device.

The advantage of the combined trolley is that the storage space after disassembly is smaller, and the advantage of the folding trolley is that it is more convenient to fold and use;

The setting of the fixing piece in the combined hand push tube can fix the combined hand push handle and the combined trolley together;

The setting of the limit adjustment hole and the limit adjustment piece can adjust the angle of the folding hand push handle;

The pivotal design of the front folding bottom plate can be folded up when the elderly want to sit, and can be used as a footrest after sitting down;

Fixing holes, fixing straps and chair fixing devices are designed to better fix objects combined with trolleys;

The pneumatic tires and large diameter of the rear wheels are designed for the comfort of the rider, and can be easily pushed for long distances. The existing trolleys have small and solid wheels, which are designed for short-distance transportation and small storage spaces. other than baby strollers;

The brake device is a mature product, which can be installed directly after purchase;

Right 3 is proposed because pneumatic tires are more common and have many sizes, and there are many ways to fix chairs, but none of them have ever been used and proposed in trolleys;

The present invention can be combined with chairs, deck chairs, baby seats, cradles, child seats and support frames to form various wheelchairs, recliner cars, baby seat cars, cradle cars, child seat cars and walking aids that can be easily implemented. Cars, etc.; and the structure is simple, cheap and high-quality, and has a wide range of uses. After disassembly or folding, the storage space is small, and it can be placed in the trunk of a private car for shopping or loading. It is a must-have car for every family.
