Description

Umbrella shank

Technical field

The present invention relates to a kind of umbrella shank that keeps umbrella, this umbrella shank is used to support and is used for the big compact umbrella that block the open air.

Background technique

Since 2000, the sale of outdoor furniture is the trend growth of 6%-7%.These increase the continuous growth that major part comes from new family and domestic regional amusement and recreation industry demand.In addition, shown that also people are to the interest of out-of-home entertainment life in recent years.

Along with the favor of people to open air life, the pursuit of people to open air life can't have been satisfied in the garden of simple vegetation formula, so the appearance of outdoor furniture has increased the functional facility of open air life greatly.Simultaneously, when the client buys outdoor leisure furniture, also more and more pay attention to the functional and aesthetic property of product, constantly order about the regional development of product towards personalization, functionalization and fashion-orientation.

The rise of outdoor leisure furniture market, begun to occur the design and the manufacturing that become increasingly complex, new technology and and various brand-new materials also extensively applied to the exploitation and the manufacturing of outdoor furniture, make outdoor furniture promote significantly in the function of the aspects such as variation of antagonism outdoor environment.Most outdoor leisure furniture can be placed on the open air safely, for example is placed on the other or slash several years of swimming pool even can be corroded good decades.Chair back cushion lining is in the indoor softness that needs, outdoor then need stand sunlight be exposed to the sun and drench with rain in improve " comfortable ", therefore, high-quality outdoor furniture must possess comfort level and strength simultaneously, and it is worth and can not be equal to simple resin chair far away.

Compare expensive high-quality timber, teak for example, characteristics such as forged steel and ironcasting have, and price is lower, and the outward appearance novelty is durable in use, and is firmly steady.Unfortunately, the iron of any classification all has a weakness: get rusty easily.Especially in the place near the seashore, any one slight indentation all can finally destroy whole decoration.In fact, the iron furniture of making in recent years is in the past few years good not, because country considers from environmental protection, bans use of plumbous as protective coating.

Compare the weakness that iron easily gets rusty, the aluminium that better selection is to use is as the production material of outdoor furniture.Except being processed into tubular frame, aluminium is the same with iron, can be forged or be cast as the exquisite device that is fit to be placed on the outdoor lawn, and exquisite bright product appearance is provided.This good performance causes the processing cost of aluminum furniture more high than iron furniture, and especially the price of Zhu Zao alumiaum article almost is the twice of identical iron piece.

Along with the requirement of people to the outdoor furniture quality, the production of outdoor furniture in recent years and make industry and be required that towards to " good ", " better ", the direction of " best " develops.And people the demand of furniture in outward appearance and design is also more and more out of doors, " the base renovation of umbrella " positive reaction this new customer demand.

Because the base of umbrella must provide enough stability when umbrella is opened, so all be to make generally by heavier cast iron.But the cast iron ratio is easier to be corroded, and not only influences attractive in appearancely, and the iron rust particle of its generation even can stain around the umbrella shank has problems stayed surface.Cast aluminium can be avoided these etching problems well, but it too light can not be for umbrella provide necessary support, so we need design and a kind ofly can resist corrosion, and the enough support forces and the umbrella shank of stability can be provided again.

Summary of the invention

The present invention is to provide a kind of umbrella shank, comprising: (a) enclosing cover, described enclosing cover has open lower, enclosing cover, interior heavily dish, and the upward opening that is used to hold umbrella handle, when described enclosing cover was placed on the flat substantially supporting surface, described pedestal just can carry the upright outdoor umbrella of rigidity; (b) heavily coil the internal surface that removably is fixed on enclosing cover by bolt in; In heavily dish be divided into up and down two dishes; Last dish is by bolt and enclosing cover internal fixation, and upward the lower end of dish has screw thread, is connected with the upper end bolt of lower wall, and the interior heavily bottom surface and the enclosing cover of dish contact to earth gapped between the plane.

This umbrella shank outward appearance has certain ornamental, and when using out of doors, can provide enough components to come drogue.The umbrella shank enclosing cover is made by the lighter decoration foundry goods of material, beautiful shape, and reserved enough built-in spaces for inner disc.Inner disc is then made by the heavier foundry goods of material.Because the iron material of internal stability is protected in the outside foundry goods, with the outside air environment isolation is preferably arranged, so As time goes on, even interior disk material variable color can not be delivered to stayed surface yet.

In this way, when umbrella handle inserted the opening that forms on the outer foundry goods, interior heavily coiling to umbrella shank provides necessary weight increased stability, and outer foundry goods covering then provides good decoration effect, and has internally folded good protective action.
