Fig. 3 is the stereogram of this device.

Fig. 4 to 6 is deformed configurations of having represented this device briefly.

Fastening devices shown in the drawings has the tubular leg 2 of one preposition one pointed parts 4, and pointed parts 4 can insert ground securely, and is firmly fixing with ground.The upper end of pillar 2 is openings, to hold the handle of receiving such as the seabeach parasol.The invention is not restricted to the fastening devices of parasol.Also can be used for the fixing of other type or structure, for example stake of tent or fence according to fastening devices of the present invention.Because a plurality of like this fastening devicess that the chain of regulating connects and combine with the earth plate of underground pillar front end can be used for fastening devices that the strand of the vehicle in emboging is pulled out.

Pointed parts 4 have have two to most advanced and sophisticated 8 assemble be roughly flat following dull and stereotyped 6 of rectangle, this flat board 6 is installed in a supporting mechanism, for example on the opposed edges of V-arrangement web 10, extend perpendicular to the plane of web 10 on the plane of each flat board 6, and each flat board extends in the both sides of web 10.V-arrangement web 10 is connected with tubular leg by transition portion 12, and transition portion has one group of inclined-plane spare 14 that tilts, and this inclined-plane spare 14 is lean-in to web 10 by pillar 2, and adjacent inclined-plane spare 14 is separated by downward and intilted floor 16.Near the lower end of transition portion 12, its pillar 2 be solid cylindrical and be whole with transition portion.

The flat flat board 18 of another rectangle to downward and interior inclination or convergence is installed in following dull and stereotyped 6 tops on the web 10, these flat boards 18 have with following dull and stereotyped 6 equal widths and are contained on the relative limit of web 10, dull and stereotyped 18 upper end is positioned at the upper end adjacent with transition portion 12, dull and stereotyped 18 lower end between dull and stereotyped 6 upper end and both do not contact, make that two covers dull and stereotyped 6 and 18 are overlapping.In this structure, be limited at the lower end of upper flat plate 18 and down between dull and stereotyped 6 the upper end at the passage 20 on each limit of web 10, the sandy soil that pour into pointed parts 4 by pointed parts 4 tops are retained in play between the inner surface of flat board 6.Upper flat plate 18 also plays a part sandy soil are collected in the pointed parts 4.

Typical this device not only can be used for the beach environment of dry tack free, bottom humidity, but also can be used for dry tack free, hard desert or other ground environment in bottom.In order to fix this device, pointed parts 4 insert the degree of depth of the sandy soil that reach moist or hard in the sandy soil, produce a leg-of-mutton hole.Then this device is taken out and removes the sandy soil of assembling in the pointed parts.Pointed parts are put back to again in this hole and shaking (in other words in the plane at Fig. 1) before and after on the planes of web 10, and dried sandy soil are poured into the inside of pointed parts 4 by passage 20.When the degree of depth that upper end that pointed parts 4 sink to upper flat plate 18 is buried by sandy soil, continue to shake the sandy soil that make 18 of upper flat plates and pour into pointed parts 4, till the hard thing that fixedly blocks in the sandy soil.In this case, the hard thing that forms in sandy soil and the sandy soil wraps up pointed parts 4, and superscribes dull and stereotyped 18.

Best stationary state is to insert fully in humidity or the hard sandy soil when pointed parts 4, and the upper end of upper flat plate 18 is shaken continuously and impelled sandy soil to pour in the pointed parts 4 when being lower than dry sandy soil surperficial.Can be sure of to embed effectively the sterosome of compacted sandy soil at this device of this stationary state.In use, because under the effect of wind-force or similar power, fastening devices shake and shaking to have dry sandy soil being poured into through the upper end of upper flat plate 18 of producing further strengthens fixing.

Described additional collection effect before upper flat plate 18 provides and added, also caused the increase of fixed range and therefore increased the bed knife that is provided, preferably as shown in the figure, outwards open the upper end of upper flat plate 18, it has strengthened this device, but also has increased the resistance of vertically pulling out.The floors of being determined by inclined-plane spare 14 16 also produce the reinforcement to this device, and increase the effect of collecting sandy soil.

In use, can obtain whole fixer, it will bear vertical pulling force.The wind-force that produces shake and shake will help to increase rather than reduce fixing effect.Sandy beach parasol for high wind load sensitivity can be fixing effectively by this device.

This fastening devices is extracted can be by a series of predetermined finishing perpendicular to shaking of web 10 planes.

Increase in the application of bed knife at needs, as at the fixing of fence post and/or when running into the dry sandy soil of the big degree of depth, the length of web can prolong, to carry the paired plate 30 of more convergence as shown in Figure 4,32, each to the lower end of plate between the upper end of adjacent following a pair of plate, what the upper end of the paired plate that increases such as front had been said outwards opens, and/or each can extend longitudinally to the lower end of the plate that increases, to strengthen web, also outwards open as shown in Figure 6 the upper end that forms the two boards 6 of pointed parts 4 as illustrated in Figures 5 and 6.

The plate of the plate that each is paired shown in Fig. 1 to 4 respectively with parallel substantially with its corresponding adjacent plate.Yet as shown in Figure 5, top paired plate can have the more inclination of wide-angle than following plate.

Pillar upper end can form perforate or otherwise hold rope as tent or similar item, and this device can be realized by the dismountable handle that is installed in the pillar or being used on every side shaken this device toward ground insertion.When this device is used for fixing the seabeach parasol, the handle of parasol can be used for this purposes.Pillar needs not to be hollow-core construction, and the pillar of other suitable structures also can use.
