Definitions

  • the present invention relates to an improved collapsible umbrella tent and specifically to an improved clevis assembly which has an improved locking mechanism.
  • the improved clevis assembly may further contain an enhanced feature for adding a separate fly adaptor assembly to which a fly sheet may be added to such tents.
  • Umbrella tents have a long history of existence and use. Collapsible umbrella tents date back to the beginning of this century and have usually included a collapsible frame on which the fabric or other flexible sheet material of the tent is supported when the tent has been erected.
  • the reference to "umbrella" tents is commonly used in the commercial trades because such tents can be erected and dismantled in much the same manner as an umbrella.
  • An example of a contemporary umbrella tent can be found in US Patent No. 4,945,936.
  • Other examples of collapsible umbrella tents can be found in US Patent Nos. 4,033,366; 3,929,146; 3,794,054; 3,000,386; 1,666,757; 1,124,420; and 1,079,757.
  • tents of the umbrella type are normally comprised of a collapsible frame which has a plurality of legs pivoted at their upper ends by a clevis assembly having an upper clevis member and a lower clevis member. Each leg has a radial stay member that is attached from the upper end of the leg and faces inward with each stay member connected inwardly to a lower clevis member.
  • the upper and lower clevis members are designed to engage when the tent is erected.
  • the upper clevis member may contain a central downwardly opening recess, while the lower clevis member contains a central upwardly projecting pin, post or rod as shown in US Patent No. 4,945,936.
  • the upper clevis member may contain a central downwardly projecting pin, post or rod, while the lower clevis member contains a central opening recess as shown in US Patent No. 3,929,146.
  • One disadvantage of these tents lie in this arrangement of the locking mechanism for the joining of the lower and upper clevis members when the tent is erected. This disadvantage is due, in part, to the torque and twist forces put on the clevis members as the tent is erected.
  • one object ofthe present invention is to improve the locking mechanism of collapsible umbrella type tents. Collapsible tents have been made with the frame exterior to the tent fabric (see for example US Patent No. 4,945,936), or with the frame interior to the tent fabric (see for example US Patent No.
  • Either type of tent can also be provided with fly covers which provide an air space between the tent fabric and the fly cover.
  • a fly cover is sometimes referred to herein as a fly sheet or simply a fly.
  • This air space can act as a water barrier and an insulator for the user.
  • a fly cover has previously been applied to collapsible tents with an exterior frame, it is desired to improve the attachment of a fly cover to the external frame collapsible tents in order to expedite the setup of the tent and fly cover.
  • collapsible tents with an internal frame do not normally have the technical design to accommodate the addition of a fly cover when needed.
  • one object of the invention is to provide a fly adaptor assembly and a modified clevis assembly for the optional attachment of the fly adaptor assembly to the modified clevis member to aid in securing a fly cover to a collapsible tent.
  • the present invention is directed to a modified clevis assembly for collapsible tents.
  • the clevis assembly is modified so that it contains a conical pin (post or rod) entry guide on a first clevis member to allow safe directing of the tip of the pin on a second clevis member into the recess of the first clevis member.
  • the pin is guided into the recess should any torque or twist to the frame occur when the tent is erected due to the inherent flexibility of the materials used in the construction of tent frames and the tendency for the user to inadvertently apply force off of vertical through pressure from the user's hands when moving the lower clevis member toward the upper clevis member.
  • the upper clevis member is modified to include a central downwardly opening recess in its under side that advantageously includes a conical pin entry guide to allow for the safe directing of the tip of the upwardly facing pin centrally located in the center of the upper surface of the lower clevis member.
  • the conical pin entry guide forms an integral part of the under surface of the upper clevis member.
  • the conical pin entry guide may be modified to include a downwardly extending shroud extension which is an integral part of the upper clevis member.
  • the lower clevis member is modified to include a central upwardly opening recess in its upper side that advantageously includes a conical pin entry guide to allow for the safe directing of the tip of the downwardly facing pin centrally located in the center of the under surface of the upper clevis member.
  • the conical pin entry guide preferably forms an integral part of the upper surface of the lower clevis member.
  • the conical pin entry guide may be modified to include an upwardly extending shroud extension which is an integral part of the lower clevis member.
  • the clevis assembly is further optionally modified to include in or on the upper clevis member means to receive a fly adaptor assembly.
  • the upper clevis member is modified to have a centrally located hollow core extending from the center of the upper surface of the upper clevis member vertically through the center of the upper clevis member out the base of the upper clevis member to the apex of the conical pin entry guide.
  • this centrally located hollow core is replaced by a centrally located fly adaptor receptacle in the upper surface of the upper clevis member.
  • the upper clevis member includes a centrally and vertically protruding pin from the upper surface of the upper clevis member.
  • the present invention is further directed to a fly adaptor assembly.
  • the fly adaptor assembly advantageously allows the user to mount the fly cover on an as needed basis on a collapsible umbrella tent.
  • the fly adaptor assembly is advantageously used with such tents in which the frame is located interior to the tent fabric.
  • the fly adaptor assembly comprises a single clevis member with a plurality of arms.
  • Centrally mounted on the underside of the fly adaptor assembly's clevis member is a means to attach the fly adaptor to the modified upper clevis member of the collapsible tent's frame.
  • the attachment means of the fly adaptor is designed to mate with the fly adaptor receiving means of the upper clevis member of the tent frame.

  • This target area can be color coded on the fly sheet 53 or secured to the upper surface of the fly adaptor assembly clevis 41 through the use of an attachment such as velcro 52.
  • the corners of fly sheet 53 are then tied down securely to the specific tie downs at the base of the legs or to the tent pins. This procedure is schematically presented in Figs. 7A-7D. Conveniently the removal of the fly sheet 53 and fly adaptor assembly 40 is a simple reversal of the procedure used to install it.
  • fly adaptor assembly of the present invention has been described to be separate from the clevis assembly, the fly adaptor assembly could be made to be an integral part of the clevis assembly.
  • the fly adaptor assembly can also be used with the clevis assembly having the shroud extension.
  • the modified clevis assembly of the present invention can be used with tent frames known in the art as illustrated by the patents set forth above.
  • One such frame, as described in US Patent No. 4,945,936, with the modified clevis assembly is shown in Fig. 8 A.
  • the upper leg sections 4 are attached to the upper clevis member 2 as previously described. At a point intermediate its length, each upper leg section 4 is provided with pivot member 60 and a radial member 14. Each radial member 14 attaches to the lower clevis member 3 as previously described.
  • Lower leg sections 61 are pivotally connected to the upper leg sections 4 by pivot connector 62.
  • the clevis assembly preferably contains four legs as shown in Figs. IB, ID and IG.
  • the clevis assembly ca be made to contain three to eight legs depending on the size of the tent. Larger tents can also be made by using more than one lower leg section for each leg, as shown in Fig. 8B.
  • the upper portion 63 of lower leg section 61 is pivotally connected to an upper leg section 4 by pivot connector 62.
  • the lower portion 64 of lower leg section 61 is pivotally connected to the upper portion 63 by pivot connectors 65.

Abstract

L'invention concerne un ensemble d'articulation modifié pour tentes pliantes. Cet ensemble est modifié comme suit: un guide d'entrée d'axes coniques sur un premier élément de l'ensemble d'articulation permet d'engager correctement l'extrémité de l'axe sur un second élément dudit ensemble dans la cavité du premier élément. L'ensemble modifié permet donc de guider l'axe dans la cavité malgré la torsion ou le tordage de l'armature intervenant au moment du montage de la tente en raison de la flexibilité intrinsèque des matériaux constitutifs d'une armature de tente et de la tendance chez l'usager à appliquer par inadvertance des forces obliques par rapport à la verticale, ce qui résulte d'une pression des mains lorsque l'élément d'articulation inférieur est déplacé vers l'élément d'articulation supérieur. De préférence le guide d'entrée de l'axe conique fait partie intégrante de la surface inférieure de l'élément d'articulation supérieur ou bien de la surface supérieure de l'élément d'articulation inférieur. A titre facultatif, on peut encore modifier l'ensemble d'articulation en y ajoutant, dans l'élément supérieur sus-mentionné ou sur celui-ci, une structure pouvant accueillir un ensemble d'adaptation de double-toit. Cette structure peut être une matrice creuse ayant une implantation centrale et s'étendant depuis le centre de la surface inférieure de l'élément d'articulation supérieur verticalement par le centre de cet élément depuis sa base vers le sommet du guide d'entrée de l'axe conique, ou bien un manchon ou une cavité support pour l'axe au sommet du guide d'entrée de l'axe conique ou bien encore un réceptacle d'adaptateur de double-toit ayant une implantation centrale dans la surface supérieure de l'élément d'articulation supérieur ou bien aussi un axe faisant saillie centralement et verticalement depuis la surface supérieure dudit élément. On décrit par ailleurs un ensemble d'adaptation de double-toit qui permet de monter un double-toit, le cas échéant sur une tente à armatures parapluie pliantes. Cet ensemble comprend un seul élément d'articulation et une pluralité de bras. En position centrale sur la surface inférieure de l'élément d'articulation de l'ensemble considéré, on trouve un dispositif de fixation de l'adaptateur de double-toit à l'élément d'articulation supérieur modifié de l'armature de la tente pliante. Le dispositif de fixation de l'adaptateur est conçu pour coïncider avec la structure dans laquelle il est introduit sur l'élément d'articulation supérieur de l'armature de la tente.
