Description

The present invention relates to a hospital and / or nursing bed with a side rail and a side rail for mounting on a corresponding bed.

With nursing and care beds is common, as in DE 201 05 036 U1 As shown, a side rail is needed to prevent a person from accidentally falling out of bed or rolling. The side rail extends on at least one of the longitudinal sides of the bed and can be brought into a use and a non-use position. In the use position, the corresponding bed longitudinal side, or at least a portion thereof, should be secured accordingly. When not in use, the long side is released, so that the user can leave the bed unhindered. The side rails should not extend above a mattress located on the bed, as this would cause an unpleasant pressure on the thigh for a person sitting on the edge of the bed. In this sense, the side rails in the non-use position should have a compact size as possible. The "conversion" from the non- to the use position and vice versa should be as simple and intuitive as possible, so that this is not possible for a technically untrained person without any special instructions. The possibility of a wrong operation should be prevented.

From these requirements, the invention is based problem of the corresponding improvement of known embodiments. This problem is solved with the features of the independent claims. Preferred developments emerge from the subclaims.

A hospital and / or nursing bed has at least one side rail, wherein the side rail comprises at least one spar, preferably at least two spars, the one or more with their ends via sliding guides relative to at least one post and / or a head or foot part of the bed are slidably mounted. In this case, the side rail on an operating element to release detents or clamps the movement of both ends of the at least one spar along the sliding guides on a single operation of the control.

The actuating direction for the release of the detents or clamps by the user is preferably done in a direction which is at least partially aligned against the direction of gravity. It thus has vectorial directional components in the negative direction of gravity. Preferably, the actuation direction with a deviation of up to +/- 60 ° and in particular of up to +/- 10 ° correspond to the negative direction of gravity. This has the advantage that the user holds the side rails (immediately) in his hand after releasing the detent or clamping. So he can hold the side rails directly, without having to perform a separate holding movement or another gripping. The above applies in particular to a horizontally oriented frame of the bed.

The detents or clamps are arranged in particular in the end regions of the at least one spar and can be mounted on the spar or on the post or on the head and / or foot part. The operating element is preferably a single operating element such as a key, a handle or a lever, a slide, etc. The term sliding guide in particular includes the functional bearing of a sliding movement of the respective end of the spar relative to the post. This does not necessarily mean that parts slide relative to each other. For example, rollers or balls may also be provided as a mediating element between the moving components. In this way, a one-hand operation is possible. The compound can be configured positively locking means or non-positively via clamps. The clamps may include brakes and / or a gear stage that, due to its characteristics, can hold the post in the erected position. This may be, for example, a worm gear stage, with the worm gear attached to the post and the worm shaft fixed to a stationary part of the side rail.

The or the spars is / are in a non-use position brought. In particular, the upper edges of the spars are not arranged or not substantially above a mattress lying on the bed and are parallel to the plane of the bed frame. At least one post can be brought into an upright position and releasable latching, clamping or holding means are provided to hold the post in the erected position. The free end of the post extends in the upright position at least 30 cm above a mattress placed on the bed, so that it can be used by the user as a handle to leave the bed. Preferably, the latching and / or holding means are adapted to hold the post in the erected position, even when the spars are in the lower, stored and the bed longitudinal side releasing position. This corresponds to the non-use position. In particular, these latching and / or holding means are designed as functionally separate from the sliding guides of the spars or components. By the described construction, it is possible to use the erected post as a stepping aid when the spars are in their lower position. In the non-use position, the pivotable part of the post (ie the pivoting post) or the post is preferably aligned in the longitudinal direction of the bed. The post comprises a pivotable as a pivoting portion which is pivotally mounted with a pivot bearing relative to the bed, in particular relative to a post lower part. Spring-elastic or pneumatic or the like tensionable means are provided to assist movement of the pivot post into its non-use position. The horizontal position of the post indicates its angular orientation in the range of +/- 15 ° to the plane of the frame of the bed. Thus, the release movement for bringing the side rail into the non-use position is preferably reduced to merely lifting the handle and placing the spars laterally on the bed at or below the mattress level within a single movement. Spring-elastic or pneumatic or the like tensionable means are provided, which are brought to a raised position during erection of the post in an upright position. The stress may be a tensile or compressive stress or rotational stress of, for example, coil springs. It is also possible to use pneumatic or other pressure accumulators. In alternative applications, a motor drive may be provided. In the upright post position, its center of gravity is above the pivot joint as a fulcrum. In order to support the pivoting into the horizontal position with the aid of gravity, an initial motion support is required by the tensionable means.

In particular, the means for bringing the pivot post into the non-use position act from an erected position of the post, starting at an angle range of 0 ° to at least 20 °.

In an angular range + 75 ° to 90 °, which corresponds to the lying position, no movement-supporting means for bringing the post into the non-use position are provided. At least in this angular range gravity is instead used to continue the Einschwenkbewegung, which reduces the design effort. Preferably, the state is excluded structurally that in one of the posts, the latching or clamping is released and he does not immediately swing into the lying position of non-use.

In particular, the releasable latching, clamping or holding means are adapted to be detachable by a movement of the at least one spar relative to the post. The latching means can be released by the downward movement of one of the spars (or both spars). Alternatively, the locking means can already be released during the upward movement of the spar or in reaching the spar of its upper position, in which the side rails comes into its locking position. Also, alternatively, the detents or clamps of the spar or the spars in the non-use position can be released due to their weight forces. In this case, for example, a spring-assisted slide can serve as a measuring sensor for the weight forces. This shifts in a weight load through the spars and can thus solve the lock of the pivot post. So no separate handle for the pivoting of the post in the non-use position is needed.

Further, damping means may be provided to limit the rate of movement of pivotal movement between the pivot post relative to a post bottom and / or the frame of the bed. Otherwise, due to the post's own weight, the pivot posts could fall into the non-use position too quickly and with a corresponding premium.

Preferably, the aforementioned control element is arranged centrally on the spar, that its distance from the axial ends of the spar on both sides in each case more than a quarter of the length of the spar amounts. The control element can also be arranged largely symmetrically and / or centrally on the spar. Thus, it is possible not to use the control element to release the detents or clamps, but the user can also grab this or the spars in the middle of the center of gravity and so easily hold with a handle.

In this arrangement, the operating element is preferably arranged like a handle in the region of the center of gravity of the spar, and the actuating direction of the operating element is aligned against the direction of gravity, so that the weight forces of the spar are received by releasing the notches or clamps on the control of the hand of an operator without that person having to do a second handgrip.

Furthermore, at least one of the spars can be telescopic in such a way that the distance of its means used for the bearing against the posts, in particular of sliding blocks, can be changed. As a result, an inclination of the spar is made possible relative to the posts.

A corresponding side rail comprises two posts for mounting on the bed and at least one spar, preferably at least two spars, which are mounted with their ends via sliding guides relative to posts. In this case, the side rail on an operating element which is adapted to solve a single operation of the control element detents or clamps the movement of both ends of the spar along the sliding guides.

Fig. 1 shows a hospital bed with two arranged on one longitudinal side rails 2 in the non-use position. Each of the side rails 2 extends over approximately half the length of the bed, so that by bringing the side rails in the position of use, the entire bed longitudinal side is secured against falling out of a person in bed. On the other side of the bed identical side rails can be arranged. Alternatively, non-openable side rails can be provided there, since it is generally sufficient if a person can leave the bed to one side. There are two independent and preferably identical side rails used, so that an incremental backup is possible in which only a portion of a bed longitudinal side is secured. Thus, it may be advantageous if only the head-side half of the bed, the side rail is closed, because then no person like that can roll or fall out of bed, falling flat on the floor or first striking the ground. But this person can move inside the bed in the direction of the foot to leave there at a non-closed side rail (this is so in the non-use position) the bed. This in particular prevents the feeling of being locked up.

Alternatively, a side rail can be used, which in each case comprises a post in the region of the head end 4 and foot end 5 of the bed 1 and so spans the entire bed longitudinal side. Also, at least one of the posts may be integrated within the head or foot portion of the bed such that the head or foot end includes a guide for the spars, and in that case the foldability of the respective post discussed below is eliminated. A respective second post may be spaced from the top and bottom of the bed and / or integrated into the head and foot ends.

In Fig. 2 a detail of one of the side rails 2, each with two posts 40 is shown. The posts 40 are composed of two parts, namely an upper part of a pivot post 40 and a lower part of a post base 60 together. The post base 60 includes attachment means (not shown) with which it can be attached to the frame of the bed 1. Via a rotary bearing 42 between the pivot post 40 and the post base 60, the pivot post 40 can be positioned within a vertical bed longitudinal direction between a flat orientation with its longitudinal axis in the bed longitudinal direction and an erect position with the post perpendicular to the plane of the bed frame is panning. Fig. 2 further shows two spars 10 and 20 secured in this position against sliding up and down.

To bring the side rail from the non-use position (see Fig. 1 ) in the position of use (see Fig. 2 ), the pivoting posts 40 are first folded up. For this purpose, the user engages in the gap that results between the mattress 3 of the bed and the pivoting post 40. When the pivot posts 40 are erected, so comes a locking tab 71 of a lock 70 (see Fig. 10 ) for engaging in a corresponding latching of the pivot post 40. Thus, a pivoting back of the post is prevented, as will be explained later in detail.

After both posts 40 have been erected, the spars can be raised so that the side rails come into the intermediate position or the use position. In order to bring the side rail into the intermediate position, the user reaches into a recessed grip 23 (FIG. Fig. 11 ) of the second beam 20 and raises it. The naming of this spar as a "second spar" and the other named spar as a "first spar" is purely arbitrary and it is not necessary that the existence of a second spar also derives from the existence of a second spar. Axially displaceable against the second spar 20 and stored in it, there is a telescopic element, which is coupled with a pivot bearing on a sliding block 26 which is guided in the sliding guide 41 of the post 40, 60. An unillustrated stop within the sliding guide 41 ensures that the second spar 20 does not have a maximum height in the Fig. 3 shown can be lifted. On the sliding block 26, a retaining wire 90 is fixed with its first end, which includes a Mitnahmehaken 92 at its other end. By the described lifting movement of the second beam 20 and the driving hook 92 is raised within the slide 41 until it engages behind the locking pivot 49 at the free end of the pivot post 40 and engages so that it can not be moved down again. Thus, the weight forces of the first and second beams 10 and 20 are transmitted via the retaining wire 90 on the driving hook 92 and from there via the pivoting pivot 49 on the pivot post 40. The retaining wire 90 is a stainless steel wire of the diameter of 2 mm, which is sufficiently rigid, that it can not be compressed within the guide exception of the pivot post 40 and on the other hand can be reversibly bent by 90 ° when placing the pivot post 40. To release the locking of the intermediate position, the corresponding actuating button 45 is pressed on the post. By means of a mechanism, not shown, in the form of two sliding surfaces, when the actuating button 45 is pressed, the blocking pivot 49 is activated via its bearing 91 Fig. 15 pivoted counterclockwise, so that the positive connection of the driving hook 92 and the locking pivot 49 is released. As a result, the package of the two spars 10 and 20 is released so that it can be stored in the release position. In the intermediate position, the upper edge of the first spar 10 is at a height level between 35% and 65% of the height level of the upper edge of the respective first spar 10 in the position of use.

On the other hand, when the user grasps the holding area 14 of the first spar 10, he can lift the first bar 10, but the second bar 20 is not moved initially. The holding area 14 is a trough-like depression, which remains constant over the longitudinal direction of the rail and below the upper edge of the rail, into which a user can grip with the fingertips. Comparable to the second spar 20, the first spar 10 also comprises telescopic elements 18 at both ends thereof, on each of which a sliding block 16 is pivotally mounted, which in turn is guided in the sliding guide 41 of the pole 40. The sliding block 16 further comprises a driving surface 17, in which the driving hook 92 of the retaining wire 90 engages only when the first spar 10 has been raised sufficiently far. Fig. 13 shows for reasons of clarity, only the driving surface 17. The additionally located in the sliding guide 41 retaining wire 90 is laterally offset in Fig. 14 shown. If after the engagement of the sliding block 16 with the driving hook 92, the first spar 10 is further raised, so due to the tensile stress within the retaining wire 90 and the second spar 20 is raised. When the first spar 10 is fully raised, so that it is in accordance with Fig. 13 comes in its upper end position, in which the side rails in its position of use, so engages a latch 19 in the locking pivot 49 and so the first spar 10 is fixed in this position. By actuating one of the operating buttons 45, the associated locking pivot 49, as already described, pivoted and so the engagement of the respective latch 19 with the locking pivot 49 is released, so that the side rails can then be brought back into its non-use position, if both actuation buttons 45 have been actuated. In the use position, the upper edge of the first spar 10 is approximately at the height level of the top of the pivot post 40th

As an alternative to the above-described solution of the locking of the first spar 10 relative to the pivot post 40 via the actuator 45, these locks can be achieved by the operation of the handle 30. Fig. 5 shows a cutout through the first spar 10. From the handle 30 go out two tie rods 36, which are fastened with their ends to the bolt 19. A spring element 19a ensures that the bolt 19 engages in the pulling up of the first spar 10 in engagement with corresponding locking pivot 49. For better explanation, see Fig. 6 the detail of the handle 30 of the Fig. 5 shown. On both sides of the handle 30, a gear 34 is arranged in each case. The handle 30 includes racks 32 which are engageable with the gears 34. In the shown, not operated Position of the handle 30, they are not engaged. This starts only when the handle 30 is raised. After the corresponding engagement of both gears, the toothed wheel 34 is rotated via the teeth 34a of the handle 30. The toothing 34b of the gear 34 has a permanent engagement with the rack portion 36b of the pull rod 36. Thus, the pull rods 36 are pulled by lifting the handle 30 in the direction of the center of the bar. This releases at the same time on both ends of the first spar 10, the latches with the posts 40 and in particular with their locking pivot 49. The described engagement of the racks 32 of the handle 30 with the teeth 34a of the gear 34 is necessary because it is thereby made possible to tilt the spar 10 in the use or non-use position, as shown in Fig. 7 is shown. The possibility of tilting facilitates the ergonomic handling of the side rail, as this way the rails within the guides can not block. The direction of movement of the user's hand when releasing the locking means of the handle 30 is directed vertically upwards, ie opposite to the direction of gravity. Thus, the user can immediately absorb the weight forces with his hand on the handle 30 when the latches have been solved. When lowering the spar 10 a diagonal position can be achieved. For the trigger handle 30 is automatically returned to its non-actuated basic position up and the teeth 32,34 is disengaged.

The guide 41 of the spars 10 and 20 within the pivot posts 40 continues down into the respective post base 60. This ensures that the spars are well guided even in the non-use position and allows the pivot posts 40 can be pivoted in this position in the horizontal position. This results in the compact package of the side grille in the non-use position, as in Fig. 8 shown from the inside of the bed.

Fig. 9 also shows the compact package of the side rail in the non-use position in a lateral section, in particular the spars 10, 20 and the pivoting post 40 are shown. The second spar 20, which is external to the bed, comprises a slip guard 25 made of a damping plastic, such as PVC. If the bed when pushing eg a door frame of a room abuts, it creates contact with this anti-slip 25. This prevents contact of eg the side rail itself with the door frame. Since the main body of the spars 10 and 20, as well as the post 40, 60 is made of a painted or anodized metal, scratches are prevented on the Holmgrundkörper by the anti-slip. Both bars 10 and 20 are guided in the same guide 41 of the post 40,60. Here are their sliding blocks 16 and 26 one above the other, which also causes, among other things, that the first spar 10 is moved when moving the second spar 20 in the intermediate position. In addition, it is shown that the second spar 20 comprises a section 22 located in front of the lying pivoting post 40. The portion 22 extends from the upper edge of the first spar 10 to the upper edge of the second spar 20 and the portion 22 has a height h in the vertical direction. In the side rail in the non-use position, the portion 22 is above the pivot point 42 of the bearing of the pivot post 40 relative to the post base 60th

The length of the extruded base profile of the second spar 20 extends in the position of use to just before the respective pivot post 40. At the ends thus resulting in each case a head piece 24 (see Fig. 2 ), which has the same cross section on its contour directed towards the bed outside, as the second spar 20, so that there is a transition without heels. The length of the head piece 24 in the bed longitudinal direction is selected such that it covers at least 80%, preferably completely, the posts 40, 60 in an area over the width of the spar. Since the head in the use position is always in the transverse direction of the bed in front of the post 40,60 a protection for both the post base 60 and the pivot post 40 against scratching when moving the bed and a sliding against an environmental structure, such as a door frame is guaranteed.

Fig. 10 shows the detail view in the lowering of the first spar 10. For reasons of clarity while the post base 60 is not shown. The sliding block 16 has at a lower end on a driving pin 16a, for engagement with the lock 70. The lock 70 is provided with a bearing pin 72, the in Fig. 10 is shown in a teilxplodierten view stored in the post base 60 and thereby rotatable about the axis A. In addition, there is a snapper 73 mounted partially pivotable about the axis B on the lock 70. During the downward movement of the driver 16 a forces are exerted on the snapper 73. Since this is at the stop of its pivoting freedom with respect to the lock 70, the pivoting movement is transmitted directly to the lock 70. Its locking nose 71 is at this time still engaged with a stop of the pivot post 40 and holds it in the erected position. As a result of the downward movement described, the locking lug 71 latches out of the stop of the pivoting post 40, and thus the pivoting post is pivotable. A tilt mechanism described below pivots the pivot post 40 in the lying position. The described mobility of the snapper 73 relative to the barrier 70 is required in the opposite position, ie the closing of the side rail in the position of use. In this case, the latch 73 pivots against a spring force upwards (see Fig. 12 ) and releases the guide 41 such that both sliding blocks 16 and 26 can slide out of the post base 60 into the pivot post 40. A spring plunger 75 causes a force on the lock 70, that the locking lug 71 engages after pivoting the pivot post 40 into this.

Fig. 11 shows an eccentric pin 48, which is secured to the pivot post 40, in a receptacle of a pressure piece 82 which is coupled to a spring 80, which in turn is mounted on the post base 60. By the urging force of the spring 80, the pivot post 40 is driven to come to the lying position. Starting from the vertical position at an angle β (see Fig. 10 ) from 0 ° to 15 ° causes the spring 80 on the pivot post 40 a pivoting force. After this angular range, a further spring support is no longer provided and no longer necessary because of the post continues to move due to gravity. In order to limit the maximum speed, a damper 84, in particular a gas pressure damper, is provided, which is connected in parallel to the spring 80 and engages the pressure piece 82.

For clarity, located within the pivot post 40 pressure piece is not shown. It extends downwardly from the actuator 45 to near the barrier 70. Upon actuation of the actuator 45, this pad is moved downwardly a step within the post. As a result, the lock 70 pivots down, and the disengagement of the locking lug 71 causes the post in the non-use position can be swiveled. This function is needed when only the post has been erected and locked in place, as is helpful when the post is to be used as a handle support for leaving the bed when the side rail function is not desired.

As an alternative to the described latching of the first spar 10 with the latch 19 to the lock 70, which describes a positive fastening, a frictional connection of the first spar 10 may be provided to the pivot post 40. In particular, this non-positive connection in the form of a brake be designed such that on one of the parts of the first and upper spar or the free end of the pivot post 40 a spring-loaded pressure element is mounted, which presses against a counter-shape of the other part, so that about Friction forces holding forces are effected. During operation of the central control element 30 or the actuator 45, this brake is then released. Due to the bias of the brake, it is ensured that the side rail does not change in the non-operation of the actuator.

As an alternative to the described operation of the tie rods 36 via tensile forces this pressure elements can be used, which press by advancing a release bolt against the locking swivel 49 and so solve the latches. This embodiment may therefore be advantageous, since in this case the described disengagement and engagement of the rack 32 and the toothing 34a is no longer necessary.

The release of the lock from the pivot post 40 to the post base 60 can also be realized via a transmission. For this purpose, an (electric) motor, which is connected to a worm shaft and, for example, is arranged on the post base 60, wherein the associated worm wheel is provided on the pivot post. Due to the self-locking characteristics of a worm gear, the post can be securely held in the upright position even when the power is cut off. With this structure, it is possible to store and erect the posts electrically and fully automatically. Furthermore, it is possible that the operating element 30 is an electrical switch, which, for example, activates electromagnets and thus releases the detents from the first bar 10 to the post. In addition, if an automatic Adjustment device for changing the height of the spars 10, 20 is provided, so a fully automatic side rails is provided in this way, which can be at the touch of a button, so a single preferred electrical operation, reciprocally moved from a non-use to a use position. In a corresponding embodiment, it is not necessary that a release of detents or clamps of the movement of the spar to the post a locking is performed, but on an inhibition of said adjusting device can achieve a corresponding clamping.

The terms "vertical", or "above" and "below" refer to a bed in which the bed frame is oriented horizontally. With an inclination of the bed frame, corresponding deviations may result, but have no influence on the above relationships.

6. The hospital bed and/or treatment bed according to one of claims 2 to 4, wherein the releasable latching, clamping or retaining means (70, 71, 73) are designed to be releasable by a movement of the at least one bar (10, 20) relative to the post (40, 60).
7. The hospital bed and/or treatment bed (1) according to one of the preceding claims, wherein the operating element (30) is arranged centrally on the bar (10), such that in each case the spacing thereof from the axial ends of the bar (10) on both sides is more than a quarter of the length of the bar (10).
8. The hospital bed and/or treatment bed (1) according to one of the preceding claims, wherein the actuating direction of the operating element (30) is oriented counter to the direction of gravity so that after releasing the elements for latching or the elements for clamping, in particular, the weight forces of the bar (10) are able to be diverted via the operating element (30) into one hand of a person actuating said operating element.
9. The hospital bed and/or treatment bed (1) according to one of the preceding claims, wherein at least one of the bars (10, 20) is telescopable, such that the spacing of the means thereof used for the mounting relative to the post (40, 60) is able to be altered, in particular, by sliding blocks (16, 26) in order to permit preferably an oblique position of the bar relative to the post.
10. A siderail (2) for mounting on a bed (1), wherein the siderail (2) comprises two posts (40, 60) for mounting on the bed (1) and at least one bar (10), preferably at least two bars (10, 20), which is/are mounted with the ends thereof via sliding guides (41) relative to the post (40, 60), wherein the siderail (2) comprises an operating element (30) which is designed to release elements for latching (70, 71) or elements for clamping the movement of both ends of the bar (10) along the sliding guides (41), via a single actuation of the operating element (30),
    characterized in that
    the posts (40, 60) comprise a pivotable portion as a pivoting post (40) which is pivotably mounted relative to the bed (1) by a pivot bearing (42), and
    means which are able to be clamped resiliently or pneumatically or at least one motor is/are provided in order to assist a movement of the pivoting post (40) into a non-use position.
