Definitions

  • the present invention generally relates to tent fittings, in particular, to a collapsible tentpole.
  • FIG. 1 a well-known collapsible tent structure is shown in FIG. 1 , it comprises canvas 2 ′ or other material stretched and sustained by poles 1 ′ and a tarpaulin 6 ′ covering the tent disposed in the top.
  • every pole 1 ′ is composed by several shafts connected by insertion into each other.
  • a sleeve tube 3 ′ is secured to every shaft, and an elastic cord 4 ′ is arranged in the shafts with both ends secured to the two endmost shafts.
  • the elastic cord 4 ′ when the shafts of the poles 1 ′ are folded, the elastic cord 4 ′ turns to be exposed to the outside of the pole, as a result, during the erection or transportation of the collapsed shafts, the elastic cord 4 ′ may easily get abrasion or break by the external or gravity force. Especially when the collapsed shafts fall onto the ground uprightly, in this case the weight of the shafts directly apply on the elastic cord 4 ′, which makes the elastic cord 4 ′ break down more easily. In addition, some metal shafts have thin walls which may be sharp enough to cut the elastic cord 4 ′ to breakdown.
  • the elastic cord 4 ′ is separated into several parts and metal chains are used to connect them.
  • the places where the metal chains interconnect the shafts are measured to ensure the metal chains, not the elastic cord 4 ′, to be exposed to the outside when the shafts are collapsed.
  • the metal chains surely have good abrasive resistance, but it takes a high cost with the material and is not easy to be processed.
  • the present invention adopts the following technology:
  • a collapsible tentpole comprising: a series of hollow shafts connected by insertion into each other; and an elastic cord arranged in the shafts with both ends secured to the two endmost shafts, wherein at least one groove is arranged on at least one end of the shaft.
  • One or more sleeve tube is secured to one end of one shaft, and the said grooves are arranged on one end of the said sleeve tube.
  • the said at least one groove is shaped into smooth arc configuration.
  • the end of a shaft or a sleeve tube is of wave configuration and the wave bottom of which forms the said at least one groove.
  • the ring end of the shaft or the sleeve tube is diagonal, and the bottom of the diagonal ring end together with the hollow interior of the shaft or the sleeve tube forms the said at least one groove.
  • the said at least one groove is a two-section groove with an upper section including two downwards extending arcs and a lower section including two grooves that extend downwards from the bottom of the upper section
  • the number of the said at least one groove is 2-6.
  • the present invention can protect the elastic cord 4 from the abrasion or break by the external or gravity force by arranging grooves on at least one end of the shaft.
  • the process is easy and the cost is low.
  • FIG. 1 is a perspective view of a conventional collapsible tent
  • FIG. 2 is an exploded view of two shafts of the conventional collapsible tent shown in FIG. 1 , illustrating the two shafts in separated position;
  • FIG. 3 is a solid view of the collapsed shafts of the conventional collapsible tent
  • FIG. 4 is an exploded view of a first embodiment of the present invention.
  • FIG. 5 is a solid view of the collapsed first embodiment of the present invention shown in FIG. 4 ;
  • FIG. 6 is a solid view of a first groove of the present invention.
  • FIG. 7 is a solid view of a second groove of the present invention.
  • FIG. 8 is a solid view of a third groove of the present invention.
  • FIG. 9 is solid view of a fourth groove of the present invention.
  • FIG. 10 is an exploded view of a second embodiment of the present invention.
  • the collapsible tentpole 1 in the present invention has the same technology as the existing art that comprises a series of hollow shafts connected by insertion into each other; the said shafts are made of high strength composite tube.
  • a sleeve tube 3 is secured to one end of a shaft, and an elastic cord 4 with both ends secured to the two endmost shafts is disposed inside the hollow shafts, as a result, the hollow shafts could insert into each other securely.
  • the different is:
  • At least one groove 5 which can receive the elastic cord 4 is arranged on at least one end of the shaft.
  • the groove 5 could be square shape, arc shape or any other suitable shape, and the depth and shape of the groove 5 are designed to receive the elastic cord 4 completely.
  • the shafts When folding the collapsible tentpole, as referenced to FIG. 5 , the shafts are separated and folded, and the elastic cord 4 is disposed within the groove 5 at one end of each shaft, thus the tentpole 1 is collapsed into a shorter and smaller form.
  • the elastic cord 4 When the folded shafts are disposed straightly on the ground, the elastic cord 4 will not get worn because of the elastic cord 4 is hidden inside the groove 5 without being exposed beyond the groove 5 .
  • the said groove 5 of the present invention may be arranged on one end of a shaft, also may be arranged on both ends of a shaft. Especially, regarding a shaft with a sleeve tube, the groove 5 may be arranged on the end of the sleeve tube.
  • the shape and number of the groove 5 can be various as long as the groove receives the elastic cord completely and supplies protection to the elastic cord. Accordingly, the scope of the invention is not intended to be defined by the shape, figuration and number of the groove.
  • the sleeve tube 3 as an example to describe the groove in different forms:
  • the grooves 5 A are two smooth arc grooves between which there are smooth transition portions.
  • the arc grooves 5 A cover the most of the end surface of the sleeve tube, so there are only two end points extending from the grooves 5 A onto the end surface of the sleeve tube.
  • the said end points are shaped into smooth arc to avoid being too sharp to cut the elastic cord 4 , thus, the end portion of the sleeve tube forms the wave shape.
  • the elastic cord 4 will not locate at the two end points of the end surface of the sleeve tube, but easily slide to the bottom of the two arc grooves 5 A and locate thereat. Thus, the elastic cord 4 is in protection.
  • the ring end of the sleeve tube 3 is diagonal.
  • the bottom of the diagonal ring end together with the hollow interior of the sleeve tube forms the groove 5 B which acts the same performance with the above described grooves 5 A.
  • the groove 5 B is also one groove figuration with the scope of the present invention.
  • the diagonal surface may be flat or curved.
  • grooves 5 C are arranged on the ring end of the sleeve tube 3 , when the shafts of the tentpole 1 are folded, the elastic cord 4 will automatically slide into a adjacent groove 5 so that the folding operation may be more convenient.
  • the groove 5 D is a two-section groove in which the upper section includes two downwards extending arcs and the lower section includes two grooves that extend downwards from the bottom of the upper section.
  • the arcs of the upper section lead the elastic cord 4 to the bottom.
  • the grooves of the lower section are seized to securely receive the elastic cord 4 so that the elastic cord 4 will not move out or get worn.
  • the groove 5 of the present invention can also be applied to metal shafts with thinner wall.
  • the tentpole 1 is made of Aluminum; a sleeve tube 3 is secured to one end of a shaft to achieve the inter-insertion among shafts.
  • the sleeve tube 3 is partly inserted into one end of a shaft and secured thereat, and the groove 5 is arranged on one end or both end of this shaft.
  • the figuration and number of the groove 5 can be the same as above described.
  • the present invention can protect the elastic cord 4 from the abrasion or break by the external or gravity force by arranging grooves on at least one end of the shaft.
  • the process is easy and the cost is low.
