Abstract
This invention concerns a device for adjusting the positions of a deckchair seat of the type with two armrests, each connected to a pair of legs by means of a top joint and each having a tubular element sliding in a guide sleeve integral with said joint. The guide sleeve (120) of each top joint (13) is provided with a stop tang (125) designed to interact with a respective tubular element (121), and a locking lever is attached to the top joint (122) facing towards and cooperating with said stop tang (125) which also turns between a released position, in which the stop tang is disengaged from the tubular element, enabling the latter to slide, and a locked position, in which the stop tang is thrust and locked against the tubular element to block it and prevent it from moving longitudinally.
Description
- This invention concerns deckchairs with variable adjustments of the seat and backrest, and refers in particular to a device for continuous adjustments of the positions of said seat.
- Deckchairs of the type taken into consideration herein which have a structure that permits varying adjustments of the seat and backrest and which can be folded to reduce the overall size for packing and transport and for storing after being used are already known. Moreover, from a previous utility model patent of the same applicant, a continuous adjustment device of the positions for the type of above-mentioned deckchair is also known and comprises: two pairs of legs converging and connected at the top by top joints; a seat linked to the legs and connected to a backrest; two armrests connecting the backrest to the top joints of the legs, and also a leg rest connected to the armrests and sides of the front part of the seat. Each top joint of said legs defines a guide sleeve and each armrest comprises a tubular element that extends and slides in said sleeve to allow the recline of the seat. Then, to carry out the positioning of the seat, each top joint is provided with a lever, which is oriented radially towards the tubular element that extends in the guide sleeve and that turns between a released and a locked position, said lever having a cam end facing towards and tightly engaging with said tubular element when it is in the locked position so as to stabilize the position of the seat.
- Such an embodiment, however, is resulted capable of improvements in order to fix and stabilize better the good order of the seat, that is the backrest and the seat, in every position and to remove in this way any risk of the locking system becoming loose and causing accidental or unintentional changes in the positions of the seat from time to time required.
- The task of this invention is to achieve this objective by means of a more secure, efficient and reliable continuous adjustment device of the positions of a deckchair, a device which furthermore is easy to reach and use and the locking action of which can only be changed intentionally.
- The objective is reached with a position adjustment device for a deckchair according to the preamble of claim 1 which basically comprises, on the edge of each top joint of the legs, a stop tang designed to interact with a respective tubular element and a locking lever facing towards and cooperating with said stop tang, as well as turning between a released position, in which the stop tang is disengaged from the tubular element allowing the latter to slide, and a locked position, in which the stop tang is thrust and closed against the tubular element to block it and avert any longitudinal movement.
- More details of the invention will however become evident in the following description made in reference to the enclosed indicative and not limiting drawings, in which:
-
Fig. 1 is an example of a deckchair with an adjustment device; -
Fig. 2 is an external view of the adjustment device in the locked position applied to an arm rest; -
Fig. 3 is a similar view as the one inFig. 2 , but with a partial cross-section and with an adjustment device in the locked position; and -
Fig. 4 is a view according to arrows A-A onFig. 3 . - The chair, to which the device of this invention is applicable and also shown in the example in
Fig.1 , , comprises: a pair offront legs 111 and a pair ofrear legs 112 connected on the upper part bytop joints 113; aseat 114 linked to the legs and connected to abackrest 115; twoarmrests 116 connected at the rear to the sides of the backrest and united with thetop joints 113 of said legs, and aleg rest 117 connected to the armrests and to the sides of the front part of the seat. The front and rear legs are also connected by acrosspiece 118, one end of which is pivoted to a respective front leg, whereas its opposite end is fixed to the rear leg by aC supporting element 119. - The
top joint 113 of each two collateral legs defines aguide sleeve 120, and eacharmrest 116 comprises atubular element 121 that extends and slides insaid guide sleeve 120, allowing the change in seat recline. - The structure of the deckchair is such that, when it is ready for use, the pairs of front and
rear legs armrests 116 and with the help of theleg rest 117. - The
tubular elements 121 of the armrests that slide in theguide sleeves 120 of thejoints 113, enable the continuous change in recline of the backrest and seat even while sitting and, once chosen, the recline is stabilised by a locking device associated with each of saidtop joints 113. - This device basically consists in a
stop tang 125 interacting with a respectivetubular element 121 and in alocking lever 122. Thestop tang 125 is provided in theguide sleeve 120, preferably attached and integral with the latter, and is relatively flexible and extends in parallel to said tubular element. It has a saddle shaped internal surface defining a concavity 125' radius equivalent to that of said tubular element and an external surface facing towards thelocking lever 122. The latter is mounted on a forked part 113' of therespective joint 113 by means of apin 123 oriented crossways as regards to the tubular element 121 -Fig. 4 . Thelever 122 turns on thepin 123 between a released position S and a locked position B and has a cam portion 124 facing towards and interacting with thestop tang 125. - When the locking levers 122 associated with the
top joints 113 of the legs are turned into the released position S, they do not engage therespective stop tangs 125 with their cam portions 124, allowing in this way free movement of the armrests so as to be able to vary the recline of the seatFig. 2 . When on the other hand thelocking levers 122 are turned into the lock position B -Fig. 3, 4 -, their cam portions 124 engage with therespective stop tangs 125 pushing and tightening them against the respectivetubular elements 121, preventing every possibility of them sliding and establishing in this way the effective recline position chosen which cannot be changed unless the said levers are intentionally moved into the release position.
