Description

Bed, especially sick or bed assistance, with side parts and / or headboard and footboard parts  partially downloadable

The present invention concerns a arrangement that forms a side part, a head part and / or a piece of footboard for a bed, especially a bed of sick or assistance, with side parts and / or parts of headboard and footboard partially downloadable, as well as to a bed with such side parts, headboard parts and / or parts of footman

They are known by the document with the number of EP publication 1 623 654 A1 some side parts of the class quoted at the beginning that comprise a top part, a part central and a bottom. The central part is scrollable with relation to the lower part of the lateral part, at least between a upper position and lower position. The provision includes also a first detachable retention means to maintain the central part in the upper position. In addition, the side part presents a first release means to release the first retention means and therefore to release the central part for its displacement from the upper position to the position lower. In addition, the upper part is movable in relation to the central part, at least between an upper position and a lower position. The upper part is held for a few seconds detachable retention means to keep said upper part in the top position. A few second means of release with which you can release the second means of retention and therefore the upper part can be released to move it from the upper position to the position lower.

The bed described in the document cited with the lateral parts, also described there, makes it possible, due to especially to the configuration of the side parts, a design especially elegant of sick or assistance beds that Set new scales. Therefore, the assistance beds according to The technical teachings described in the cited document are Especially successful in the market.

However, the maneuver of the first and second means of release has been perceived as cumbersome by some  bed users according to the technical teachings described in the cited document. In particular, it has been perceived as cumbersome which, to introduce the upper parts of the lateral part, is have to manipulate the handles of the second release means in the upper part, while, to maneuver the first means loose, handles must be handled in the central part. This does that at least one change in the attack points of the hands or hand.

To remedy this circumstance and satisfy the wishes of the users, the invention has been based on the problem of improving side parts of the class cited at principle so that the introduction of the whole side from an upper position to a lower position possible With a handle.

This problem is solved according to the invention by the fact that the first release means are mounted on the upper part and said first release means are suitable for release the first retention means in the lower position of the upper part and therefore release the central part to move it to the lower position. However the first means of release to release the first means of retention, which establish the union between the central part and the bottom, are mounted on the top, the part side can be configured so that it can be sufficient maneuver a single handle and, without changing the attack point of the hand, the entire side part can be transferred from the position higher than the lower position.

The first means of retention of a arrangement according to the invention may comprise a bolt which, in the upper position of the central part, enclave this central part with respect to the bottom. The first means of retention they can also comprise a spring which, in the upper position of the central part, keep the bolt in a position of interlock or move it to the interlock position.

The first release means may comprise a scroll element that is suitable and is prepared to move the bolt from the interlocking position to a release position.

The upper part, the central part and the part bottom of an arrangement according to the invention may comprise the minus a respective post part. The respective pole parts of the upper part, the lower part and the central part can jointly form an extendable pole telescopically. The top post part can be introduced then advantageously, at least in part, in the central post part and this part of the central post can be advantageously introduced, when less in part, in the lower pole part.

Several pole parts of the top, the central part and / or the lower part can be joined one with another through one or several stringers and can thus form frame-shaped or U-shaped structures.

In an arrangement according to the invention the first release means are preferably mounted on the lower end of the top, especially at the end bottom of the pole parts of the top. For him on the contrary, the first retention means are mounted advantageously at the lower end of the central part, especially at the lower end of the pole parts of the central part.

Bolt and offset element can jointly form a mechanism to transform a movement of the scroll element in a first direction in a bolt movement in a substantially perpendicular direction to the previous one. The downward movement of the element of displacement can thus become a loose movement or a bolt unlocking movement in direction perpendicular to said displacement element. Due to the fixation of the first release means and, therefore, also of the medium of displacement at the lower end of the upper part, especially at the lower ends of the pole part of the upper part, an unlocking of the bolt when lowering the upper part. No performances are necessary specials that go beyond the descent of the upper part with Regarding the central part.

The bolt and the displacement element of a mechanism have two surfaces that slide over each other when moving the bolt. The surfaces of the bolt and the element of displacement may be arranged obliquely with respect to the first direction in which the upper part can move and especially the pole part of the top.

Figure 13, a view of the side part taken from below according to arrow XIII of figure 8 and

Figure 14, a perspective representation of the bed according to the invention with four downward side parts in a superior position.

The bed shown in figure 14 has a lower frame 7, but of which only the legs are appreciated of support that appear below an upper frame 8. The bed it rests on a floor with the lower frame 7. The frame upper 8 of the bed rests on the lower frame 7. This upper frame 8 of the bed comprises a lying part 9. The lying part 9 is configured in a usual bed way of assistance or sick. That is, the lying surface of the lying part, on which a mattress can be placed, is adjustable in many ways in its inclination. On the surface lying down 9 is mounted a framing comprising a part of headboard 10, sides 40 and a piece of footboard 41. The part headboard 10, sides 40 and footboard part 41 are joined together forming a frame in a way known for the beds, enclosing the frame lying surface 9 of the bed.

The bed according to figure 14 presents on each side two downward side parts 2, 3; 4, 5. These side parts, with their upper end located in a higher position, they are so high as the footboard part 41 of the bed. In a position lower down side parts end in the area of the upper end of sides 40 and are then projected on the lower position until beyond a mattress placed on the lying surface 9 (not shown).

The side part represented in figures 1 to 13 has a lower part U, a central part M and a part upper O. In an upper position of the side or, said more precisely, from the top O of the side, the Parts O, M, U are separated from each other (Figure 1, Figure 6, figure 9), and in a lower position of the lateral part or of the upper part O of the lateral part the parts O, M, U are plugged into each other (figure 3, figure 8, figure 11, figure 13). In between, several central positions can be occupied. The arrangement of the different parts O, M, U with respect to each other it differs here according to whether the central positions are occupied at remove or when introducing the side part. Intermediate position depicted in figure 2 deals with retracting the side part and the same goes for the position represented in figure 10, while the intermediate positions represented in the figures 4 and 5 are reached by extracting the lateral part.

The lower part U of the lateral part has two parts of pole 31 spaced apart from each other. The parts of Post 31 are formed by sections of aluminum profile. The parts of post 31 are joined with the lying part 9 of the beds to through holes 32 and screws not shown. For the ones screws can be screwed into the lying part 9 have provided holes 32a through which it can be introduced  a screwdriver on the pole part 31 so you can reach Screw head, not shown. In the parts of post 31 of the lower part U of the lateral part are arranged in shape movable two pole parts, also sections 21 of profile aluminum of the central part M of the lateral part. These two post parts 21 join each other, on the one hand, at the end bottom through a bottom spar 25, using screws 29 and, on the other hand, at the upper end through a crossbar upper 20, inserting screws 28. The lower beam 25 and the upper beam and the two pole parts 21 form a frame  approximately rectangular

The pole parts 31 of the bottom U of the side part are split on the inner side, so that the stringers 20, 25 of the central part M can be guided in the post parts 31 of the bottom U.

The upper part O of the lateral part presents also some parts of post 11, also of profile sections of aluminum. These pole parts 11 are joined with a crossbar 13 using screw 19 and together with the beam 13 form a approximately U-shaped structure. On the crossbar 13 is fixed a wooden handrail 10 for framing.

On the bottom side of the crossbar 13 is screwed between the two pole parts 11 of the upper part O an advantageously U-shaped sheet 12 in cross section, the which, in a lowered position of the upper part OR of the part lateral in relation to the central part M of said lateral part, hugs the upper crossbar 20 of the central part M. In addition, in an upper position of the upper part O in relation to the central part M reduces the height of the free space above the upper beam 20. For technical safety needs, this space may not exceed a certain measure.

In order to freeze or lock the part central M of the lateral part in an upper position in relation to a lower part M of the lateral part is provided mechanism comprising first retention means for keep the central part in the upper position and a few first release means for releasing the first retention means and, therefore, to release the central part in order to displace it from the upper position to lower position.

The first retention means have a bolt 27 which is mounted on the lower end of the parts of post 21 of the central part M transversally movable to the extension direction of the pole parts 21. Bolt 27 crosses a recess of the post part 21 and penetrates a recess 311 of the pole part 31 of the bottom. The 311 recess It is provided in the area of the upper end of the pole part 31. The central part M is thus maintained in the upper position.

The retention means also comprise a spring 27a that rests, on the one hand, on the inner side of the inner wall of the post part 21 and, on the other hand, in a heel of bolt 27. Spring 27a drives bolt 27 into recess 311 of the pole part 31 of the bottom U.

Bolt 27 features a peripheral collar that it has a lateral surface or flank 271 that is arranged in oblique position with respect to the direction of movement of the bolt 27. This surface 271 cooperates with the first release means to effect a release of the joint between the bolt and the central part, on the one hand, and the post part 31 of the part lower U.

The first release means is formed by a plastic molded part which is then called the element of displacement 16. The displacement element 16 has two cams arranged at a distance from each other, each of which it has a surface 161 located obliquely with respect to the direction of movement of the first part 11 of the part higher. The displacement element 16 is mounted on the upper end of the post part 11. The distance between the two cams with oblique surfaces 161 has been sized so that the cams can be applied on bolt 27.

The interlocking release between bolt 27 and the central post part 21, on the one hand, and the post part 31 of the lower part U, on the other, is done by lowering the part of post 11 of the top O until the cams of the element of displacement 16 be applied with oblique surfaces 161 of the displacement part 16 on bolt 27. The surfaces obliques 161 are then applied to surfaces 271. Simultaneously with the downward movement, bolt 27 is then pressed out of recess 311 against the spring pressure 27a, specifically because the element of displacement 16 with oblique surfaces 161 cooperates with the bolt through the oblique surfaces 271 thereof, moving to said bolt 27.

When bolt 27 has been removed from recess 311, the central part M can be lowered with respect to the part bottom U to put the side part in the bottom position, such as this is represented in figures 3, 8, 11 and 13.

The upper part O and the central part M of the side part can be interlocked against each other by means of a adequate mechanism The mechanism is associated with the pole part 11 of the upper part O. An element of the mechanism is a bar trigger 14 acting as the second release means, which is arranged in the post part 11 in a scrollable manner in height. You get a particularly good guidance of this bar shot 14 by means of appendages 14c that laterally guide the trigger bar 14 in the aluminum profile. To the extreme upper of the firing bar 14 is shaped, by multiple couplings, a 14c trigger handle that is accessible from the outer side of the bed in a position located immediately under the handrail.

In an upper appendix 14c of the bar shot 14 is formed a mandrel 14a that is directed towards above. A compression spring is seated on this mandrel 14a 14e. This compression spring 14e rests, on the one hand, on the Appendix 14c and, on the other hand, leans against the crossbar 13. The mandrel 14a prevents buckling of the spring 14e under compression load.

The lower end of the firing bar 14 is housed and guided in a hole of the sliding element 16. In addition, the displacement element 16 also serves as sliding element of the post part 11 of the part upper OR in the post part 21 of the central part M. By the same reason, slip sleeves 24 are provided in the upper end of the pole parts 21. Both the element of displacement 16 as the sliding sleeves 24 prevent a Direct friction of the post parts 11 and 21 one to another. At the upper end of the pole part 31 are provided also sliding sleeves 32 of this kind that prevent a direct friction between the parts of post 31 and the post part 21.

In the area of the lower end the bar shot 14 has an attack chamfer in its zone 14d. In this zone the trigger bar 14 extends through a recess of a second bolt 15 acting as a second retention means. This bolt 15 serves to lock the upper part O with respect to the central part M of the lateral part. The attack chamfers in the zone 14d of the firing bar 14 are arranged here so which, when a pulling action occurs on the firing bar 14 upwards due to a maneuver of the firing handle 14c in against the pressure of the spring 14e, the bolt 15 is inserted into  the post part 11. The bolt 15 then provides a recess 22, provided that the upper part is in an upper position, or a recess 23, provided the top is in a position central, as it is represented, for example, in the figure 2.

If the trigger bar 14 is released, for which the firing handle 14c, the spring 14e is released press the trigger bar 14 down. The 14d zone of the bar firing 14 which is provided with the attack chamfers is then displaced in the recess of the bolt 15 so that said bolt 15 be pressed out. The bolt can fit then in recess 22 or recess 23, depending on the position of the upper part O of the desired side part in relation to the central part M of the lateral part.
