10 Claims.

This invention relates to a convertible hammock tent and support therefor. The hammock tent is provided with a supporting frame which is readily taken apart. The flaps of the tent are readily separated and folded back. The tent can be readily folded and rolled up with the separated parts of the frame and hammock inside, making the entire device into a small roll which is readily portable. The frame is adapted to support the hammock as well as the tent, the former being located inside the tent. The frame is of yieldable resilient construction providing a comfortable give to the hammock. The tent is readily converted into several forms. By properly folding back the front, rear and side flaps it can be converted into a sun shade. The upper portion of the frame which supports the roof covering or parts comprises rafters adjustably mounted so that they can be set at different angles to each other and with respect to a fixed axis, enabling the roof parts to be set in various positions to suit changes in the location of the sun. Another form into which the tent can be converted by proper folding of the flaps is a lean-to. The lower frame can be used by itself as a hammock support. Said latter frame can be used by a slight modification to support the hammock as a deck or beach chair. A modified form can be used as a sun bathing tent enabling the occupant to be exposed to the sun and still be hidden from View.

Other objects and advantages will become apparent upon further study of the description and drawings in which:

Fig. 14 is a perspective view of the device in partly packed condition, and

Fig. 15 shows the device in completely packed condition, the frame members, rafters and hammock being rolled up in the tent fabric.

Referring now particularly to Figs. 1, 6, '7, 8, 9 and 10, the lower frame comprises a substantially 40 U-shaped member having tubular uprights 5 and a longitudinal base member formed of bowed tube l with elbows 3 fixed at its ends. Uprights 5 have a sliding fit in elbows 3, each upright having a pin ll, Fig. 6, which fits into a notch in the upper end of an elbow 3. A bowed bottom cross arm 2 is pivotally attached at its center by bolt 4 to the underside of tube l which is slightly stamped in, Fig. 3, for'locking cross arm 2 at right angles to tube I when wing nut I2 is screwed tight.

The upper end of each upright 5 is bent at an angle with its lower portion, so that the former extends in avertical direction when the device is set up for use. Said upper end is adapted to receive slidably an extension piece 6 whose upper portion is flattened as readily seen in Fig. 5. A pin I6, Fig. 4, is provided on extension piece 6 which fits into a suitable notch, Fig. 4, provided in the upper edge of upright 5' to prevent rotation of said piece. The flattened upper portion of extension piece 6 has fixed therein a bolt 23, Fig. 5, upon which are pivotally mounted friction disks I0. Eachdisk ID has extending therefrom a rafter I. When wing nut 22 is screwed up on bolt 23 the disks I are frictionally held in any set position. As a further aid in holding and setting disks III in predetermined positions, holes 24 are provided in the disks, a hole is also provided at the top of the flattened end of piece 6 and a pin 30 is inserted through the holes when a hole of each of the disks is brought into register with the hole in piece 6. Holes 24 in disks III at one end of the structure bear the same angular relation to the rafters I extending therefrom as do the holes 24. in disks I0 at the other end of the structure to their rafters. This ensures the setting of the corresponding rafters at each end of the structure at the same angle, with reference to a fixed axis for a'purpose to be given later..

Each upright is provided with a hook 9. A hammock 8 is slung between hooks 9.

A tent having various flaps and covering parts is supported by the rafters I. The roof parts I5 are stitched together to form a ridge 40. The front and rear ends of roof parts I5 are hemmed around rafters .1 as seen in Fig. 5. Loops of cord 25, Fig. 5 are attached to parts I5 near their ends at ridge 40. Each loop is caught on the end of a spring I8, the other end of said spring being mounted on hook 2 .I fixed to the head of bolt 23 which is embedded in the flattened portion .of extension piece 6. Side flaps I4 are fastened to roof parts I5 along eaves 4|. A similar arrangement for fastening the flaps at eaves M to rafters :"I is used as for fastening the parts at ridge 40. Springs I9 are attached to rafters I and to the flaps at the ends of eaves 4I, one such spring being shown at the right side of Fig. .1. Springs I8 and I9 serve to keep roof parts I5 taut between rafters l at all times even when'hammock 8 is loaded and uprights 5 are deflected thereby.

, Front and rear end flaps I3 are fastened to roof parts I5 at rafters I, there being two end flaps I3 at each end of the tent with their inner ends overlapping and adapted to be fastened by snap fasteners 42. End flaps I3 have a small extension 43 at their outer extremities carrying snap fasteners 20 which detachably hold side flaps I4 at their lower portions. This permits side flaps I4 to be detached from flaps I3, when it is desired to fo-ld'flaps I3 or I4 back over roof parts I5 as seen in Figs. 8 and 9. Fig, 8 shows said flaps in the process .of being folded back, the down or original position of said flaps being shownin dot and dash lines. In Fig. 9 said flaps are shown folded and tied back over the roof parts.

Lash cords II, whichare fastened to side flaps I4, can be used when it is desired to stake thetent to the ground. The same cords can be used to tie back flaps I4 when it is desired to hold them folded back on roof parts I5 as seen in Figs. '7, 9 and 10.

When it is desired to use the device as a shade instead of a tent, the flaps are folded back, Fig. 8, into the position shown in Fig. 9, end flaps I3 being folded in under side flaps I4. By means of the adjusting mechanism shown in detail in Fig. 5 and previously described, rafters at each end-can be set at various angles toeach other to vary the slope of the shade. The use of pins in holes 24 ensures that there is no warped surface in the tent fabric stretched between the front pair of rafters I and between the rear pair of rafters I when said pins are set in corresponding holes, as the rafters of each pair then make the same angle with a fixed axis.

In Fig. 10 the device is used as a lean-to, front flap I4 and the forward portions of side flaps I3 being tied back over front roof part I5, and the rear portions of side flaps I3 being tied back over rear roof part I5. The dot and dash line for the forward roof part I5 indicates said part in another position from the horizontal one shown by the solid line. Such change in position is desirableto suit the changes in the suns location. The

dot and dash lines at the sides show the way the rear portion of the side flaps I 3 may be let down for further shelter.

In Fig. 11, the device is shown converted into a beach chair. The tent covering is removed and the front upright removed and replaced by a shorter upright 26. Hammock 8 is suspended between hooks v9 carried by the uprights.

When it is desired to fold and wrap up the device for carrying it about, the front and rear flaps I4 and side flaps I3 are disconnected from each other and tied back over roof parts I5 as shown in Fig. 7. The roof frame is removed from the lower frame by lifting extension pieces 6 out of uprights 5. Bottom cross arm 2 is turned parallel to longitudinal base member I into the dot and dash position shown for it in Fig. '7. Nuts 22 are loosened, rafters "I at each end are turned to make an angle of 180 degrees with each other and extension pieces Ii are turned parallel to the rafters. However before tying the forward ends of the front and rear flaps I4 over the roof parts I4, as seen in Fig. 14, the frame memhers I and '5 are disconnected from each other, cross arm 2 remaining attached to base member I and placed parallel to the forward pair of rafters I under flaps I4. Hammock 8 can then be laid on top of fiaps I4 and the whole business then rolled up from the forward end and tied up with straps 21 as seen in Fig. 15. The center strap 21 is provided with a handle :28.

In Fig. .12 a modified form of tent is shown in which sun bathing can be done in private. A roof part 49 is cut out soas to have an opening 4?. Covering over this opening is a sun bathing flap 50 which can be turned down along eaves 4 I. When the tent is to be closed, fasteners 48 hold sun bathing flap 4! to roof part 49.

Instead of having, as in Fig. 10, a lower frame in which the base member I and uprights 5 all have their axes in substantially a vertical plane, the frame shown in Fig. 13 has these parts with their axes making an angle with such a plane which is shown in dot and dash lines. Said plane passes through the axes of bolt 4 and the upper vertical portions of uprights 5. Elbows 3 are set on the ends of base member I inclining inwardly and oppositely toward said plane causing uprights 5 to incline in opposite directions toward said plane. Cross member 45, which is longer than cross member 2, inclines oppositely to base member I, when the frame is set up for use, making substantially the same angle with said plane as does said member.
