Description

The invention relates to a bed, in particular in the embodiment as a hospital and / or nursing bed, with a bed frame and two end portions arranged on each end, being provided for positionally secure arrangement of the end parts on the bed frame tool-operated fasteners.

Beds of the generic type are well known from the prior art, which is why it does not require a separate documentary evidence at this point.

Beds of the generic type have a bed frame and two end parts, typically a Fußendteil on the one hand and a headboard on the other. The end parts are arranged on the bed frame, in each case on the front side. So they take in the final assembled state of the bed on the bed frame between them.

The bed frame can be configured in any desired manner. Typically, it is designed as a frame construction. It can also be filled to stiffen. In any case, he serves to support a lying surface element in the final assembled state of the bed, for example in the design of a slatted base. In this case, the lying surface element may also be designed in several parts and have pivotable relative to each other Liegeflächenelementabschnitte. The lying surface element in turn serves to receive a cushion element, preferably a bed mattress.

Beds of the type described above are often in use and have in the proven practical application. Nevertheless, there is a need for improvement, especially with regard to a simplified assembly or disassembly at the site.

For reasons of simplified transport, in particular using standardized transport units, such as pallets, it is common practice to spend a bed in the disassembled state to use or use. There it is then to be assembled by expert staff. Such an installation is time consuming and can also be labor-intensive depending on the size of the bed, since usually a fitter is not sufficient on site. In case of dismantling, the same results.

From the prior art devices for plug connection of furniture parts are known, for example from the US 470246A showing the connection of a post to a plate. For the purpose of the plug-in connection, a push-in tab is used, which passes through the slots of an abutment in the mounted state. The abutment pivotally carries a cam lever, which prevents unintentional separation of the tuck from the abutment in the closed position.

Based on the above, it is the object of the invention to further develop a generic bed to the effect that due to the design allows a simplified assembly or disassembly.

To solve this problem, a bed of the type mentioned above is proposed with the invention, which is characterized in that the fastening means are manually operable clamping connector, wherein a clamping connector has a cooperating with a clamping means actuator, wherein the clamping means is fork-shaped and a first and Having a second spring leg, which receive the actuating element of the clamping connector at least partially between them.

For the connection of the bed frame and end parts, instead of the screw connections typically used according to the prior art, fastening devices which can be operated without tools are used according to the invention. These allow uncomplicated and quick assembly or disassembly, even by non-specialist personnel.

The fastening means provided according to the invention can be pre-assembled by the manufacturer. Thus, it is in contrast to the prior art no longer necessary to make a setting of the fasteners on site, which on the one hand saves assembly or disassembly time, on the other hand avoids any incorrect assembly, whereby a correct and thus safe bed construction is guaranteed. Since the inventively provided fasteners are also operated without tools, eliminating the need to carry appropriate tools, which is slimmed down the required logistics for a bed construction and it is also possible in the case of disassembly without any knowledge of tools to make a disassembly as intended, so that non-specialist personnel a such Dismantling can make.

The provided according to the invention bed consists of only three modules, namely a bed frame, a first end portion and a second end portion. These assemblies are pre-assembled by the manufacturer and equipped for later intended use of the bed. Thus, in particular, the bed frame is equipped with a lying surface element, any drives for adjusting individual Liegeflächenelementabschnitte, wiring, electronics and / or the like. At the place of use, only the end parts which are not connected to the bed frame by the manufacturer for transport purposes are to be mounted, which is done quickly and reliably by means of the inventively provided tool-free operable fastening means.

According to a preferred embodiment of the invention it is provided that the bed frame is formed in several parts, being provided for positionally secure connection of Bettrahmenteilen tool-free operable fasteners.

According to this preferred embodiment, the bed frame is made in several parts, preferably in two parts. Such a subdivision of the bed frame is particularly advantageous for reasons of simplified transport. To connect the individual bed frame parts - as well as for the connection of the end parts with the bed frame - tool-free operable fasteners are used. Thus, the bed frame can be mounted quickly, reliably and safely at the place of use by the individual bed frame parts inserted into each other and connected together by means of tool-operated fasteners secure together, that is coupled.

According to this embodiment, the bed consists of four structural components to be assembled at the place of use, namely a first bed frame section, a second bed frame section, a first end section and a second end section. These components are pre-assembled by the manufacturer and have all the necessary components for a proper use of the bed. At the installation site, first the bed frame parts are to be connected to form a total bed frame. Then, an arrangement of the end parts takes place on the mounted bed frame. Then the bed is mounted properly used.

The fastening means according to a feature of the invention are manually operable clamping connectors. By means of this clamping connector, the individual structural components of the bed are clamped together, whereby the position-safe arrangement is achieved. In contrast to the prior art therefore takes place in particular no screw.

According to a further feature of the invention it is provided that a clamping connector has a cooperating with a clamping means actuator. To form a position-secure and permanent connection, a clamping means on the one hand and an actuating element on the other hand are provided, which are in operative connection with each other. In this case, the actuating element serves to solve a clamping connection formed by the clamping means or to produce such, depending on the position of the actuating element. On the user side, an actuation of the actuating element, as a result of which there is either a loosening of an existing clamping connection or producing a clamping connection. In this case, the user-side actuation of the actuating element takes place without tools in accordance with the invention.

According to a further feature of the invention it is provided that the clamping means is fork-shaped and has a first and a second spring leg, which receive the actuating element of the clamping connector at least partially between them. The clamping device provided according to the invention is Y-shaped in the manner of a fork. It has a first spring leg and a second spring leg. These two spring legs can be moved relative to each other, causing a strain in the expanded state. The adjusting element of the clamping connector is arranged at least partially between the two spring legs, so that upon actuation of the adjusting element, the spring legs are widened. It can therefore be effected by manual actuation of the actuating element, a relative movement of the spring legs to each other, which leads depending on the operating direction of the actuating element to a width or a compression of the spring legs.

The tensioning means cooperates according to a further feature of the invention with a provision of abutment-providing clamping means. In the final assembled state of the bed, the clamping means is therefore against the abutments of the clamping means receiving and is based for the purpose of strained arrangement against this. I'm disassembled, that is dissolved state, the clamping means is made powerless, whereby a supported concern is resolved to the associated abutments. In the released position of the clamping means can therefore take place a mounting or dismounting, which in the assembled state, a position-safe arrangement of the individual components is achieved when the clamping means is set, it therefore rests supportingly on the associated abutments.

According to a further feature of the invention, the clamping device receptacle is a square tube. This provides the abutments through its interior surfaces. In the final assembled state, the clamping means is located on the inside of the square tube and is supported in a secure connection with this set from. The tension is thus achieved in that the spring legs of the clamping means are pressed in the rebound state inside of the square tube to this, whereby a clamping connection between the clamping device-carrying component on the one hand and the square tube providing component on the other hand is made.

According to a further proposal of the invention it is provided that the square tube is formed as part of the bed frame. This embodiment proves to be particularly compact and easy to use. In particular, it is not necessary for the provision of cooperating with the clamping means abutment to provide additional components. The already existing bed frame is used as an abutment for the clamping device.

The clamping connector has according to a further feature of the invention via a bolt which receives the actuator longitudinally displaceable. In the intended use case, the actuator is therefore guided longitudinally displaceable by the bolt, so that in the case of actuation a one-to-one guidance of the actuating element for the purpose of loosening or forming a voltage connection is ensured.

The bolt carries einendseitig a rotatably disposed thereon handle. This handle is designed, for example, in the manner of a handle extension and can be taken and handled by the installer in the intended use case. The handle interacts with the actuator. As a result of manual actuation of the handle, a displacement movement of the actuating element is achieved. The displacement movement of the actuating element in turn has the consequence in the already described manner that depending on the direction of rotational movement of the handle, it either becomes one Loosening an already set clamping connection or forming a clamping connection comes.

In this case, the handle according to another feature of the invention on the bolt side a guide contour ready, which cooperates with the actuating element. The formation of a guide contour has the advantage that a permanently safe and accurate interaction of handle and actuator is given. For example, the guide contour may be concave with respect to the pivot about which the handle is pivotable. The actuator provides a correspondingly formed counter contour.

The actuating element is designed in two parts according to a further feature of the invention. It has two sections, namely a first section which cooperates with the clamping means and a second section which cooperates with the handle. The first portion of the actuator cooperating with the tensioning means preferably provides a cone. This cone engages in the final assembled state between the two spring legs of the clamping device. As a result of an actuation of the actuating element for the purpose of forming a clamping connection of the first section providing the cone of the actuating element moves in the longitudinal direction of the bolt of the clamping connector in the direction of the clamping means. As a result, the cone plunges deeper between the two spring legs of the clamping means, so that it comes to a rebound movement of the spring legs and thus to a tension of the clamping means relative to the clamping means recording. To disassemble the clamping connection, the handle must be turned on the user side in the opposite direction. As a result, the actuator is allowed to travel in the opposite direction along the bolt. Since the spring legs act on the cone providing the first portion of the actuating element spring-loaded, the actuating element is automatically pressed along the bolt in a direction opposite to the clamping means, whereby the adjusting element at least partially herausverfährt from the space between the spring legs, so that the spring legs can deflect, what releases the clamping connection.

The embodiment of the invention proves to be particularly advantageous because it allows a fast to be performed, safe and a little expensive assembly or disassembly in contrast to the prior art. About that In addition, it can be performed without tools, whereby it is also not trained personnel allowed to carry out a proper assembly or disassembly. In addition, the inventive design allows less labor-intensive assembly or disassembly work, so that all in all, the assembly or disassembly can be carried out less time consuming and costly.

The embodiment of the invention also offers a further advantage. Thus, the inventively provided fastening means can also be used to design transport packages of different sizes. Thus, it is provided for transport purposes, the individual components of the bed, that is to say to connect bed frame parts and end pieces for transport safely together. Serve this purpose, the inventively designed fasteners. Since these tools can be operated without tools, it is allowed to convert the transport items combined into a package individual components of the bed also convert, that is to rebuild a different transport package. This has the advantage that it is possible to differentiate between a truck transport on the one hand and a bully transport on the other hand, wherein the conversion from a transport package for a truck to a transport package for a bully can be carried out in a simple manner thanks to the embodiment according to the invention. A transport package for a truck typically builds up comparatively high, but is comparatively narrow in the width direction. It is thus allowed to accommodate an optimized number of disassembled beds on a single pallet. However, such a transport package is not suitable for further transport with a bully. This is not because the loading space of a bully typically fails in height direction smaller than that of a truck, so relatively high-build transport packages can not be accommodated in the hold of a bully. Thanks to the inventive design, the transport package but can be retrofitted in a lighter and easy to be performed way, namely to a size suitable for a bully load size, according to the transport package builds less high, but in the width direction is somewhat sweeping. To achieve this, the fastening means provided according to the invention are loosened without tools, the individual structural components of the bed subsequently reassembled in a new orientation and fixed again by means of the fastening means provided according to the invention. With conventional fasteners, such a conversion is not possible, so that the embodiment of the invention also insofar advantageous proves to simplify warehousing, logistics and transportation organization.

Further features and advantages of the invention will become apparent from the following description with reference to FIGS.

FIG. 1 shows the bed 1 according to the invention in sections, with an end portion 3 and 4 and a square tube 12 of a bed frame 2 can be seen.

The end part 3 or 4 serves as the foot or head part of the bed 1 and has a transverse bar 20 and two longitudinal bars 21 arranged therein. The transverse bar 20 and the longitudinal bars 21 carry tabs 22 which correspond to the arrangement of a decorative element, not shown in the figures, For example, serve a wooden plate.

The longitudinal bars 21 are further each equipped with a clamping means 9, wherein a clamping means 9 cooperating with a serving as a clamping device receiving 12 square tube of the bed frame 2. For the sake of clarity, only a square tube 12 is shown in the figures.

As can be seen in particular from the presentation FIG. 2 shows, a clamping means 9 has two spaced-apart spring legs 10 and 11, which are spaced apart Arrangement form a gap between them. In the final assembled state affects each clamping means 9 with a fastening means 5, that is, a clamping connector together, as in the FIGS. 5 a to 5 c is shown in different views.

The clamping connector 5 has a bolt 13 which carries in the final assembled state einendseitig a nut 19. At the other end, it has a handle 14. This is arranged pivotably about a rotation axis 23 on the bolt 13. For this purpose, the bolt 13 has an eye provided with an eye.

The clamping connector 5 also has an actuating element 8, which is received in the longitudinal direction of the bolt 13 displaceable by the bolt 13. In this case, the adjusting element 8 is formed in two parts and has a conical disk 16 and a washer 17th

In the final assembled state, the handle 14 rests with its bolt-side guide contour 15 against a counter-contour 18 provided by the washer 17. This operative connection of the handle 14 and washer 17 requires that the washer 17 can move in the direction of the longitudinal axis of the bolt 13 during a twisting movement of the handle 14, wherein it moves the washer 17 either in the direction of the nut 19 depending on the direction of rotation of the handle 14 or the movement of the washer 17 is released so that it can migrate in the opposite direction.

The interaction of clamping means 9 and clamping connector 5 results from a combination of the particular Figures 2 and 4 ,

For mounting the bed 1, the bed frame 2 is attached with its square tubes 12 to the respectively associated clamping means 9. As a result, the bolt 13 of each clamping connector 5 moves into the gap formed between the spring legs 10 and 11 of the respectively associated clamping means 9. This mounted position is in FIG. 4 shown. For position-safe connection is now the user side, the handle 14 of the clamping connector 5 to use. As a result, the actuator 8 moves in the space between the two spring legs 10 and 11 of the associated clamping means 9, wherein the clamping connector 9 by means of its nut 19 on the outside of the square tube 12 is supported. As a result of this movement of the Control element 8 moves the cone plate 16 in the space between the two spring legs 10 and 11, which causes a spreading derselbigen. They lie on the inside of the square tube 12, so they brace against the square tube 12. The square tube 12 serves as an abutment for the clamping means 9, wherein the spring legs 10 and 11 press on the inside of the square tube 12 to this. As a result of the movement of the adjusting element 8, the square tube 12 is also pressed with its in the figures above wall inside on the clamping means 9, so that a total of three-sided concerns of the square tube 12 takes place on the clamping means 9. In this clamped position of the clamping connector 9 a position-safe and durable connection of the square tube 12 and thus the bed frame 2 at the end part 3 and 4 is ensured.

For the purpose of dismantling the clamping connection is to be solved, for which purpose the handle 14 of the clamping connector 5 is zurückverwenken in the starting position. The extent provided by the handle 14 eccentric is thereby solved, so that the adjusting element 8 is released in its movement in the direction of the handle 14. The spring legs 10 and 11 can spring in this released position and press the actuator 8 from the intermediate space formed between them, whereby the clamping connection between the clamping means 9 and square tube 12 is dissolved. In this released position then the square tube 12 can be deducted from the clamping connector 9, that is, a disassembly of end part 3 or 4 and bed frame 2 take place. <B> LIST OF REFERENCES </ b> 1 bed 18 mating contour 2 bed frame 19 mother 3 End part (foot part) 20 transverse spar 4 End part (head part) 21 longeron 5 Fastening means (clamping connector) 22 flap 8th actuator 23 axis of rotation 9 clamping means 10 spring leg 11 spring leg 12 Clamping device holder (square tube) 13 bolt 14 handle 15 guide contour 16 first section (cone disk) 17 second section (washer)
