In Sweden August 30, 1933 1 Claim.
The present invention relates to a tent of the kind wherein the tent skeleton consists of a plurality of tent poles interconnected at the top, and wherein at the place of their junction a slidable vertical rod is arranged which engages the top part of the tent duck and serves for stretching the duck.
The main novel feature of the invention consists therein that the tent poles each are made in two parts connected by means of a joint over which the duck is stretched, when the pole parts are turned out of mutual alignment as the vertical rod is pushed upwards in counter action to the duck.
It is preferable to interconnect the top ends of the tent poles in the known way by means of a common connecting member in which the slidable rod is guided, and, according to the invention, the tent poles are pivotally connected to the said connecting member by means of two pivots perpendicular to each other, one of the pivots being vertical when the tent has been erected. The erection of the tent will be greatly facilitated by thus providing a pivotal connection of the poles in two directions perpendicular to each other An embodiment of the invention is illustrated by way of example on the accompanying drawings.
Fig. 1 is a perspective outside view of the erected tent, and Fig. 2 is a vertical section through the same, wherein for the sake of clearness only two opposite tent poles have been fully shown.
Fig. 3 shows, partly in section, an elevation of the upper connecting member and adjacent parts.
Fig. 4 is a plan view of said connecting member adapted for 8 tent poles.
Fig. 5 shows in elevation a detail of the lower pole part and the joint connecting the two pole parts.
Fig. 6 shows in section an attachment provided with a spark arrester for the passage of a smoke conduit through the duck The tent illustrated by way of example on the drawings is erected on a skeleton, consisting of a number of tent poles, which below are pointed and driven into the ground, and their tops are interconnected by means of a connecting member, disclosed in detail in Figs. 3 and 4. Each tent pole consists of two parts, I designating the upper and 2 the lower pole part, which are pivotally connected by means of a joint 3 (Figs. 2 and 5). This joint consists of two end pieces 5 and 6, of which one may be fork-shaped, and which are pivotally connected by means of a pin 4. The end pieces are provided with bores for inserting the ends of the pole parts as illustrated. By this arrangement the tent poles may be folded together when the tent is being transported. To secure the joint 3 in adesired angular position one or several holes may be provided in the 5 end pieces forming the joint for the insertion of a locking pin 3a or the like.
The upper ends of the upper pole parts 2 are inserted in bores of end pieces 1 (Fig. 3), which by means of pins 8 are pivotally connected to con- 10 necting parts I3 that by means of vertical pins i2 and nuts M are pivotally jou'rnalled in a connecting member, which substantially consists of a vertical sleeve l0 provided with a horizontal flange 9. In the flange 9 a number of holes II corresponding to the number of pins l2 are provided. Either the end pieces I or the parts l3 may be fork-shaped. Thus, the pole parts 2 are connected to the connecting member by means of two pivots 8 and I2 perpendicular to each other, whereby the erection of the tent will be greatly facilitated.
A vertical rod l5, the upper end of which supports the centre of the top of the duck is slidably passed through the sleeve It). When the tent is to be erected, the rod I5 is pushed upwards, until the duck has been sumciently stretched. Thereupon the rod I5 is secured to the sleeve III. For this purpose, a number of holes l6 are provided in the rod l5 and two diametrically opposed 0 grooves I! are provided in the wall of the sleeve. When the rod occupies the right position a pin I8 is inserted through the hole nearest to the bottom of the grooves 17 so as to secure the rod. The lower edge of the duck is secured to the hooks 26 provided on the pointed ends 21 of the pole parts I.
The tent is secured to the ground preferably by means of ropes 28 attached to the top of the rod l5 and tent-pegs driven into the ground, suitably with the aid of an intermediary rope 30 and a stretching member 29 as illustrated.
When the rod I5 in the described way is pushed upwards stretching the duck, the latter exerts a counter pressure on the rod, which causes the pole parts I and 2 to be turned outwards about the joints 3, thereby stretching the duck over the joints.
According to the invention, protection against moisture and draught is effected by attaching a protecting cloth below the joints of the pole parts along the circumference of the tent to the inside of the duck, for example by means of push buttons or by sewing so that the cloth will hang down towards the ground.
ground. The edge 2| may The protecting cloth is designated by l8 in Fig. 2. The upper edge of the same is attached by means of push buttons 20 to the duck at such a level that the lower edge 2| will rest on the ground, when the tent is erected. It may then as illustrated be folded towards the centre of the tent and may be attached to the be covered by a cloth or tarpaulin 3| forming the floor in the tent. Between the suspended cloth l8 and the duck stretched over the lower pole parts an insulating interspace 22 is formed which prevents the penetration of moisture and draught.
According to the invention an interior ceiling in the form of a cloth 23 is arranged, which is supported and stretched by the upper pole parts 2, the lower edge of the cloth 23 being attached to the inside of the duck I9 along its circumference and adjacent to the level of the joints 3 of the poles, for example by means of push buttons 24 or by sewing. At the centre of the cloth 23 an opening is provided with a diameter corresponding to the width of the connecting member. By this arrangement a tight, warm and, above all, moisture-free roof of the tent is obtained owing to the formation of an insulating interspace 25 between the outer duck 1-9 and the interior ceiling 23.
The tent according to the invention may also be provided with an attachment which makes possible the use of a fire-place, a furnace or stove in .the tent. For this purpose an attachment is secured to the outer duck for the pascured to the attachment.
sage of a smoke conduit from the fire-place. Such an attachment is shown in Figs. 2 and 6. 32 designates a furnace or stove placed inside the tent. Its smoke conduit 33 is passed through an opening 34 in the duck, suitably arranged between the fastenings of the cloth I8 and the inner ceiling 23. Said attachment consists of plates 36 of refractory material, such as asbestos, eternite or the like, which plates are provided with openings for the passage of the smoke conduit and arranged on opposite sides of the duck and connected by bolts 35 with wing nuts. On the outside of the duck a spark-arrester is se- The spark-arrester may for example consist of four sheet metal plates 31 secured to the outside plate 36 by means of hinges so that the plates 31 can be put up towards each other, and connected, thus forming a spark-arrester together with a funnel 38 or the like inserted in the open end of the smoke conduit, as illustrated in detail in Fig. 6. The spark-arrester may, however, be of any other suitable design.
Having now particularly described the nature of my invention and the manner of its operation, what I claim is:
A tent having a tent skeleton consisting of a plurality. of'tent poles pivotally connected at the top -to;a common connecting member by meansof twopivots perpendicular to each other, one of said pivots being vertical when the tent is erected.
