Definitions

  • the present invention relates to a chair with pivotable legs.
  • the chair of the invention is particularly suitable as a shower chair in shower rooms.
  • Elderly person and persons suffering from any kind of disablement may require seating furniture for bathrooms in different situations requiring different properties.
  • a stool devoid of arm- and backrests may be most appropriate.
  • a seat surface that can be placed on a frame structure fixedly arranged in the bathing tube is preferable. Accordingly, it is an objective of the invention to provide a shower chair that can be easily adapted to a specific use or to the preferences of the user.
  • the present invention addresses the problems depicted above.
  • the present invention relates to a foldable chair with pivotable legs.
  • the present invention relates to a foldable shower chair comprising at least four legs connected to a seat surface support structure, said chair having a first, unfolded and stable position of use and a second, folded position in which the chair occupies less space than in said first position, wherein said legs can be pivoted to change from said first to said second position and vice versa, said chair being characterized by the features defined in claim 1.
  • situations and directions of the chair and elements thereof are determined by the perspective of a user seated in the chair. Accordingly, the left side of the chair corresponds to the right side of Figure 1 and vice versa.
  • the situations or directions “up” or “top” and “down” or “bottom”, “rear” or “back” and “front”, “behind” and “in front”, “distal” and “proximal”, “lateral” and “central” follow the same rule.
  • the term “ longitudinal” indicates a direction of an element, such as a tube, having, as a major direction component, the rear-to-front direction. Such an element may also to some or to a minor extent be skewed laterally and or towards the bottom or the top.
  • Figure 1 shows the chair of the invention comprising four legs 3-6 carrying a seat surface support structure 7.
  • the upper surface of the seat surface support structure forms the seat surface 28.
  • the chair comprises left and right lateral armrests 60, 70 and a backrest 80, all of which are independently removable, as will be seen in the following figures.
  • the seat surface support structure and thereby also the seat surface 28 comprises a central recess 90, in the front, central part of the seat surface support structure 7.
  • the recess may extend over at least one quarter, for example at least one third of the breadth and at least one quarter, for example at least one third of the rear to front length of the seat surface support structure.
  • the recess is provided in order to facilitate cleaning of the intimate areas of a user, in particular for elderly or disabled persons suffering from a reduced mobility.
  • the legs 3-6 of the chair shown in Figure 1 are provided in the form of telescopically guided, inner and outer tubes, allowing the adjustment of the height of the chair by way of a lockable telescope mechanism.
  • the bottom of each leg designed to reside on the floor when the chair is put in place comprises a cap 61-64, which is preferably made from a material that is suitable to prevent gliding and/or improve adhesion of the chair on smooth and/or wet surfaces as is often the case in bathrooms, shower cabins or bathing tubes. In this way, the danger of slipping or falling down is reduced.
  • the cap's material may comprise rubber.
  • Figures 2 and 3 show the chair of Figure 1 with the backrest and both armrests, respectively, being removed.
  • back- and armrests 60, 70, 80 are all attached by way of a click mechanism to the seat surface support structure 7.
  • the click mechanism is preferably such that said arm and backrests can be manually removed without need of any tool and/or without the need of performing any unscrewing.
  • the click mechanism of the arm and backrests may be based on the flexibility of the material of the back- and/or armrests and/or of the seat surface support structure. A preferred material possessing these flexibility characteristics is plastic.
  • the seat surface support structure 7 comprises a pair of left and right openings 61, 71, suitable to receive structures provided on the left and right armrests 60, 70 ( Figure 1 ) accurately and snugly fitting into these openings.
  • openings are provided in the rear end of the seat surface support structure 7, which cannot be seen in the figures, but which follow the same principle as the armrests.
  • the removability of the back- and/or armrests of the chair of the invention provide several advantages in terms of adaptability and user friendliness.
  • the chair can be adapted to more situations given in specific shower rooms and to the preferences and capacities of a user.
  • the chair as shown in Figure 3 with arm- and backrests removed may be advantageously used, because it does not hinder any movement of the user sitting on the chair in the cabin.
  • Figures 4-10 show the chair of Figure 3 (arm- and backrests removed) in an up-side-down situation, thereby revealing the way the legs 3-6 of the chair are attached to the seat surface support structure 7.
  • FIG. 5 shows in greater detail the rear and front right side legs 3, 4 of the left side of the chair. It is noted that the right side is arranged in a mirror imaged manner and that the discussion below with respect to the left side seen in Figure 5 also applies to the right side. It can in particular be seen that the rear and front right side legs 3 and 4 are rigidly connected with each other by way of a connection profile 39 extending in a longitudinal reat-to-front direction in parallel to the seat surface 28.
  • the connection profile 39 is straight and connected, as illustrated at the front end of Figure 5 , by way of two successive bends in different directions 29, 30 to the profile of the front right leg 4 of the chair. The same applies to the connection of the rear end of the connection profile 39 with the rear right leg 3.
  • the pair of rear and front legs of one side 3, 4 thus form a U-shaped profile together with the connection profile 39 of the right side of the chair.
  • the legs 3-6 are unfolded and rigidly secured to the seat surface support structure 7 ( Figure 4 ).
  • the elements that rigidly fix the two legs of one side of the chair are on the one hand two brackets 41 provided in a rigid manner on the seat surface support structure 7, in which the left connection profile 39 connecting the left rear and front legs 3, 4 is placed.
  • a clamp 45, 46 is provided, which constrains the tubular connection profile 39 to the seat surface support structure. The clamps 45 and 46 can be removed, as illustrated in Figure 6 .
  • each leg a clip holder element 8-11 is provided, which will be described further below.
  • the clip holder elements 8-11 are retained in their position by way of a clip-mechanism 31-34, which allows the manual detachment of the holder element from its position.
  • the holder elements 8, 9 of the legs 3 and 4, respectively, of the left side of the chair are shown in exploded form, that is detached from their usual position as shown in Figure 4 .
  • Each holder element 8-11 comprises two functional parts, namely a clip mechanism 31-34 and an element forming part of a locking mechanism.
  • This latter element is, in the embodiment shown, provided in the form of a pin 12-15, which engages with structures provided in the respective leg and the seat support structure thus locking these together, as will be described hereinafter.
  • Figures 5 and 6 only the left side of the chair is shown, the same situation applies on the right side, and reference numerals are generally indicated for the structural elements of all legs of the chair, some of which can thus only been seen in other figures.
  • the functioning of the holder element will now be detailed at the example of front leg 4 and the corresponding holder element 9 as seen in Figures 5 and 6 .
  • the holder element 9 of the left front leg 4 is shown in a disengaged position.
  • a pin 13 can be seen as well as a band 32 having the shape of an open circle.
  • the band 32 and the pin are rigidly connected by way of a connecting bridge, which does not carry a reference number.
  • the entire holder element 9 is a one-piece element.
  • the band 32 constitutes at the same time the clip-mechanism 32, since it can be engaged in a clip-like manner around the leg 4, as shown, for example, in Figure 4 .
  • This clip 32 can be removed by hand from the leg and replaced around the leg by hand, too.
  • the clip mechanism is thus realized by the elasticity of the band 32, which is made, for example, of an elastic metal or plastic material, and which is such that little force only is required to unclip the hold element 9 from the leg 4 or to clip it onto the leg, respectively. Still, the clip 32 is sufficiently rigid to prevent spontaneous falling off from the leg without specific and directed manual drawing force being applied by the user.
  • the retainer structure 25 is rigidly connected to the seat surface support structure 7 and may be made as a one piece element with the latter, or may be fixed by ways of screws or welding.
  • the retainer structure 25 has a shape that partially surrounds and thus harbours the upper end of the left front leg 4 when the latter is in the unfolded position.
  • the leg 4 also comprises a bore 17, which cannot be seen in Figure 5 and 6 , because it is covered by the retainer structure 25 in this position.
  • the bores 16, 17 in the legs 3 and for of the left side of the chair can, for example be seen in Figure 7 .
  • the pin 13 can be placed through bores 21 and 17 in the retainer structure 25 and the leg 4, respectively, and is sufficiently long to extend into a second bore in a reinforced part 36 of the retainer structure 25. Therefore, when the holder element 9 is placed on the leg 4 as shown in Figure 4 , the pin 13 is stably harboured and locked within said bores 21 and 17 and thus rigidly locks the leg 4 within or to the retainer structure 25 of the seat surface support structure 7.
  • Identical holder elements 8, 10, 11, retainer structures 24, 26, 27, bores 20, 22, 23 in the respective retainer structures and bores 16, 18 19 are provided with respect to the three other legs 3, 5, 6 of the chair 1 in identical manner as can be seen from the various figures. Since pairs of left and right lateral legs 3, 4; 5, 6 are rigidly connected with each other, it is necessary to remove the two clip holder elements 8, 9; 10, 11 of one side in order to be able to pivot the legs of one side downwardly, as described further below.
  • connection profile 39 and 40 are secured to the lower surface of the seat surface support structure 7 and by the way the legs 3-6 are individually locked by way of a manually removable clip holder elements 8-11 to retainer structures 24-27 applied rigidly in the four corners of the seat surface support structure 7, as all discussed above, the mechanism of folding and unfolding the legs 3-6 becomes apparent.
  • FIG 8 shows the entire chair 1 corresponding to the extract of Figure 5 , with the clip holder elements 8-11 being removed, for example by the user of the chair.
  • Each pair of legs 3, 4 and 5, 6, respectively, is now pivotable, with the axis of pivoting being the tubular connecting profile 39, 40, of the left and right side of the chair, respectively. Since, for example, legs 5 and 6 of the right side are rigidly connected via the connecting profile 40, they can be pivoted only together. Furthermore, due to the situation and form of the retainer structures 26, 27, an outward pivoting movement of the legs 5 and 6 is prevented by said retainer structures, which not only stabilise the legs, but also block them in the outward direction.
  • brackets 41-44 and clamps 45-48 are fixed by brackets 41-44 and clamps 45-48 to the seat surface support structure 7, as described above.
  • said brackets and clamps surround the respective connection profile and thus allow for a rotational movement of the tubular connection profiles 39, 40.
  • Figure 11 differs from Figure 10 only in that the clip-holders 8-11 are clipped again on their respective legs 3-6.
  • the upper ends of the legs 3-4 are not harboured or in contact with the retaining structures 24-27 and the pins of the clip holders do thus not pass through the bores 20-23 provided in said retaining structures.
  • the pins 12-15 are simply placed in the bores 16-19 of the legs 3-6. This can best be understood from comparing Figure 10 , where the bores 16-19 are visible, with Figure 11 , where the clip-holders 8-11 are provided at the positions of said bores.
  • the chair of the present invention can easily and conveniently be folded by hand without the need of any tool and/or without the need of any particular skills.
  • the folded shower chair can be stored and transported in a particularly space-efficient manner.
  • the chair of the invention is particularly useful as a shower chair, that is a chair that is preferably to be used in bath-rooms, including shower cabins, and the like.
  • the seat surface support structure 7 and also the seat surface 28 is preferably made from plastic material.
  • the caps 61-64 may be part of a screw-based mechanism, which allows slight modification of the length of the legs, so that all legs can be optimally placed on the floor even on uneven ground.
  • the legs 3-6 can be completely removed from the chair by opening the clamps 45, 46; 47, 48 provided on each side of the chair and retaining the legs at the connection profiles 39, 40 on brackets 41, 42; 43, 44 (the brackets 43, 44 of the left side of the chair can be seen in Figure 4 ).
  • the seat surface support structure can be fixed on a different support than legs, for example onto a support frame that is provided on a bathing tube or on a wheelchair.
  • the same brackets 41-48 and clamps can be used for fixing the seat surface support structure to such a support frame.
  • a rigid frame (not shown) can be installed on a bathing tube and the chair of the invention can then be fixed on this frame.
  • the user can than freely add or remove each of the armrests and/or the backrest independently, as desired.
