Description

TITLE

ROLLATOR FUSE UNIT FOR A TRANSPORT

TECHNICAL AREA

The present invention relates to a rollator securing unit of a means of transport, in particular a public transport means such as a bus, train or tram.

STATE OF THE ART

Walkers, also called rollators, are walkers for elderly or handicapped people. They enable mobility without outside help and, in particular, they are easy to take along in public transport. Public transport now has satisfactorily functioning fixation and securing means for bicycles and wheelchairs. For rollators suitable fuses, in which the rollator does not have to be folded, but are hardly available.

WO 2014/177344 Al discloses a device in which the wheels of the rollator are blocked. The adjustment of the braking device from a release position to a braking position is preferably carried out by means of an electric motor, which is actuated via a switch. This device is relatively complex and expensive and susceptible to interference.

In DE 10 2012 023 157 B4 a securing device for rollators is described, in which a linkage in the form of a parallelogram kinematics is attached to a vehicle wall and can be unfolded as a partition. This allows the walker to park in a newly formed space. Optionally, fold down a folding seat on which the passenger can sit and hold the rollator. The folding seat can be pivoted more than 90 °, so that it is on the seat of the rollator to come to rest. This device is relatively complicated to use for older people, since on the one hand the partition and on the other hand the folding seat must be operated. In addition, the folding seat does not provide sufficient security, since it rests obliquely on the seat in most cases. Furthermore, sitting on an inclined surface is relatively uncomfortable and for an older passenger mostly not possible because of the movements of the vehicle. Furthermore, many rollator models have a back support that makes it impossible to use a folding seat.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a for the Rollatorbenützer easy to use and safe for him Rollator safety device for transport, especially for a public transport, such as a tram and a bus.

This object is achieved by a rollator safety unit having the features of patent claim 1.

The rollator securing unit according to the invention has a support element, which secures the rollator in its position by resting on a seat surface of a rollator in the case of an external load of the support element from above. The support element forms a horizontally extending support surface whose height is variable.

Preferably, the support element is height adjustable when used as intended and it forms in different height settings a horizontally extending support surface.

The Rollatorbenützer can thus safely seated on this support surface. By sitting on he brings the necessary to secure the rollator external load on the support surface. Since the support surface in a height suitable for the user in the horizontal position can be brought, the user himself can also sit securely and must not laboriously hold his position by force with his legs. J

In a simple embodiment, the support element is formed only by one or more strips, which are placed on the seat surface of the rollator. The user then sits on the one hand on this at least one strip and on the other hand on the seat of his rollator.

Preferably, the support element is flat and designed as a seat for a Rollatorbenützer. The support element thus forms a continuous seat for the user.

Depending on the embodiment, the support element is rigid or flexible. In a flexible embodiment, the support element is formed, for example, as a flexible one-piece mat or in the form of a mat formed from interconnected individual members. In a flexible embodiment, the height adjustment of the support element is preferably formed by the fact that it can be flexibly bent down to the desired height or up and forms a horizontal extending surface at the desired height, for example by resting on the seat surface of the rollator. Not the entire mat itself must be brought to the desired height.

Preferably, the support element against a spring force in a horizontal position of use can be brought and returned by the spring force in a vertical position back. As a result, the Rollatorbenützer when leaving the means of transport must not return the fuse unit itself in its former position. This would otherwise be forgotten.

In a preferred embodiment, the securing unit has a vertical rod for attachment to an interior of the means of transport, wherein the support element is pivotally arranged about the vertical axis and pivotable about a horizontal axis. This is a simple solution, which also has the advantage that the support element is visible to everyone and the operation of the fuse unit is easily recognizable.

Preferably, the support element must only about the vertical axis to about the Rollator seat can be pivoted so that the user can sit on it. By sitting on the support element is lowered onto the rollator and this is secured.

Preferably, in this embodiment, a sliding bushing is present, which is spring-loaded along the vertical rod in the vertical direction displaceable and pivotable in the horizontal direction about the vertical rod. A horizontal pivot arm is firmly connected to the sliding bushing. A horizontal pivot axis is arranged at right angles to the pivot arm on this and the support element is designed as a seat plate, which is arranged on the pivot axis. This arrangement is very simple, robust and inexpensive and can be optimally integrated into the bay or niche for wheelchairs and strollers of transport, such as buses and trams. For example, it can be attached to existing tubular separations, which run transversely to the direction of travel.

In another preferred embodiment, the securing unit has two parallel and vertically extending posts for attachment to an interior of the means of transport. The two posts have a guide for the support element, which is vertically displaceable upwards and pivotable at different heights in a horizontal position. Such an arrangement can be attached, for example, in a simple manner to a vehicle interior wall and only minimally so that it takes up little space when not in use.

Preferably, the support element is designed as a rigid seat plate. This preferably also applies to the two preferred embodiments mentioned above.

The seat plate is formed in one embodiment throughout stiff. In other embodiments, it has at least two rigid areas, which are connected to each other via a crease or a pivot axis. In this case, a first rigid region can be formed as a head part with a free end, which forms a handle.

In other embodiments, the support element is designed as a flexible seat mat. This seat mat can also be preferably provided with a flexible or a rigid headboard with handle. In one embodiment, the flexible seat mat consists of interlocking mat members which form a plurality of buckling axes distributed over the length of the seat mat. Preferably, the flexible seat mat is pulled out of a housing, wherein a return mechanism for retraction of the seat mat is arranged in the housing in the housing. The use of a housing with pull-out seat mat in turn allows a space-saving training, which also has no protruding elements when not in use, to which passengers could get stuck with their clothes. In one embodiment, the seat mat is retracted flat, in another embodiment, it is rolled up.

Also in the embodiment with a seat mat, a return mechanism is preferably provided which retracts the seat mat automatically into the housing. Preferably, there is a time delay and / or a damper. For example, a mechanical timer for the withdrawal of the seat mat is arranged in the housing. In a preferred embodiment, the return mechanism includes a scroll spring, a tension roller and a tension curve along which the tension roller extends, wherein the scroll spring is tensioned by pulling out the seat mat from the housing. This is a simple and robust, but very effective training. In another embodiment, a tensioning lever in the form of a spring-loaded pivoting arm is tensioned, wherein a driver is moved along a guide during the time delay.

The described embodiments and in the sense of the invention designed variants thereof are inexpensive to manufacture, easy to use and robust.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1 to 5 show a first embodiment of a rollator securing unit according to the invention. It is part of an interior of a public transport, e.g. a bus or tram. There are no seats in this section, but it is designed as a cove or niche for prams, wheelchairs and rollators. An interior 1 of such bays usually has a vertical bar 10, and horizontal bars 11 and / or partitions 13 for separation from the seats. To this end, they are limited by a side wall 12 of the vehicle.

The inventive fuse unit 2 can optimally be arranged in such a bay. Other locations within the vehicle may also be appropriate depending on the design of the vehicle.

A vertical bar 20 of the rollator securing unit 2 extends from the vehicle floor to one of the horizontal bars 11, which is preferably at least 70 cm, preferably at least 1 m above the vehicle floor.

At this vertical rod 20, a seat plate 24 is pivotally and vertically adjustable. The seat plate 24 is preferably rigid. Preferably, it is plane-parallel. It is preferably rectangular, being oval in other embodiments or having another suitable shape. The height-adjustable and swivel mount can be done in different ways. In this example, a sliding bushing 21 is present, which surrounds the vertical rod 20 and is displaceable in the longitudinal direction of this and pivotable about it. Below the sliding bush 21, a stop bushing 26 is fixedly connected to the vertical rod and between the two bushings 21, 26, a return spring 25 is arranged.

On the sliding sleeve 21, a radially projecting, horizontal pivot arm 22 is arranged on which a perpendicular thereto extending, horizontally extending pivot axis 23 is mounted. On the pivot axis 23, the seat plate 24 is pivotally mounted.

When not in use, the seat plate 24 is directed vertically upwards, as can be seen in Figure 1. Preferably, the seat plate 24 engages in this position so that it can not fold down automatically during movements of the vehicle or it is otherwise fixed in this position. These latching or fixing agents are well known and therefore not shown here.

A rollator 3 can be pushed next to this securing unit until it rests against the side wall 12 of the vehicle. The seat plate 24 can then pivot by hand in the direction of rollator 3, as shown in Figure 2. In Figure 3, the seat plate 24 is above a seat surface 30 of the rollator 3. It can now fold down, with a non-visible stop the fuse unit, the seat plate 24 is fixed or latched in the horizontal position. These funds are well known and not shown here. The seat plate 24 can thus preferably be pivoted by approximately exactly 90 °.

Now sets a passenger on the seat plate 24, the sliding sleeve 21 moves against the spring force down until the seat plate 24 rests on the Rollatorsitzfläche 30. This position is shown in Figure 5, wherein the passenger is not drawn himself. The rollator is thus fixed in position and can be transported. At the same time, the Rollatorbenützer can sit on his rollator and does not have to search without a rollator a seat. Will the Rollatorbenützer leave the vehicle, he just gets up. The return spring 25 then raises the seat plate 24 back to its usual height and the Rollatorbenützer need only swing back to its original position to remove his rollator from the niche can. Since the rollator would still be blocked by pivoting the seat plate 24 back by the clamped handle 31, it is ensured that the rollator safety unit is returned by the user himself back to its original position.

This unit is very easy to produce and the vehicles can be easily retrofitted. The rods are preferably made of metal and the seat plate made of metal, wood or a suitable plastic.

FIGS. 6 to 10 show a further embodiment of the rollator securing unit 4 according to the invention. It is preferably in turn in the niche of the vehicle, which is designed for walkers, wheelchairs and prams. The unit is preferably arranged on the side wall 12 of the vehicle. However, it can also be fastened to a wall extending transversely to the direction of travel.

The securing unit has two vertically and mutually parallel post 40, which are connected to each other via an upper cross member 41 and a lower cross member 41 ⁴ . The mutually facing inner sides of the posts 40 have guides 47, in which a displacement rod 45 is held displaceably in the vertical direction. On the sliding rod 45, a seat plate 42 is pivotally mounted. It can preferably be pivoted by a maximum of 90 °. In other embodiments, it can be adapted to an inclination of the seat surface of the rollator, which can also be more than 90 °.

The seat plate 42 is preferably rigid. The upper end of the seat plate 42 is connected via a pivot or a bending axis 46 with a head part 43. The head part 43 is preferably also stiff. It has a passage opening which forms a handle 44. This unit is preferably made of metal, wherein the seat plate 42 and the head part 43 made of metal, Wood or a plastic are.

In FIG. 6, the device is in the starting position. The seat plate 42 extends flat between the two posts 40, the sliding rod 45 is moved down to a stop 470. In Figure 7, a walker 3 is parked in front of the unit, wherein it is present on the unit and / or on both sides of the unit on the side wall 12 of the vehicle.

The Rollatorbenützer can now, as can be seen in Figure 8, pull on the handle 44 and the head part 43 and the seat plate 42 pull out. This can be done in different ways. In this example, the head portion 43 is first folded down (see Figure 8) and then the seat plate 42 is pulled up, whereby the sliding rod 45 along the guide 47 moves upward (see Figure 9). When the desired height is reached, the seat plate 42 is placed on the rollator seat surface 30. Depending on the width of the Rollatorsitzfläche 30 and the head part 43 is horizontal on the seat surface 30 or it is bent downwards. The first case is shown in FIG. The Rollatorbenützer can in turn sit comfortably on the seat plate 42 and thus secures his rollator.

Will the Rollatorbenützer leave the vehicle, he gets up and raises the headboard 43 and the seat plate 42 again. As a result, the displacement rod 54 shifts along the guide 47 back down, either due to a return spring or by its own weight. Depending on the embodiment, a mechanical, hydraulic or pneumatic brake is installed to decelerate the case of the shifting rod 45. This unit has the advantage that the rollator user can focus on getting out of the car and does not first have to bring the safety unit back to its original position.

FIGS. 11 to 19 show a third embodiment. This embodiment has the advantage that it can adapt optimally to the depth of the rollator seat surface 30 and thus allows the user a similar sitting feeling as when sitting directly on the rollator seat surface. This rollator securing unit 5 is also preferably arranged on the side wall 12 of the vehicle in the aforementioned bay or niche. However, it can also be arranged on a transverse to the direction of travel wall and / or at another suitable location in the vehicle interior.

This rollator securing unit has a housing 50, which is preferably formed completely closed except for an upper slot in a front wall 51. The housing 50 forms an interior, in which a support element in the form of a flexible seat mat 54 is arranged. The seat mat 54 terminates in a preferably stiff head part 53 with a passage opening, which forms a flange handle 52. The head part 53 with the handle 52 projects out of the upper slot of the housing 50 in the starting position, as can be seen in FIG.

The rollator 3 in turn is in contact with this housing 50 and / or on the side wall 12 of the vehicle. The user can now pull the seat mat 54 out of the housing 50 and over the seat surface 30 of his rollator, as can be seen in Figures 12 to 14.

The seat mat preferably consists of individual mat members 541, which engage in one another and thus form buckling axes 540 at a plurality of locations. As a result, it can be optimally adapted to the width of the rollator seat surface 30, as can be seen in FIG.

If the height of the rollator seat surface 30 does not correspond to the height of the slot, the seat mat 54 can nevertheless be brought to the desired height since it is designed to be flexible. The individual members can be easily bent relative to each other until a horizontal seat is formed.

The seat mat 54 is preferably made of plastic.

In the housing 50, a mechanism is arranged, which allows easy withdrawal and automatic retraction of the seat mat 54. Thanks to the automatic retraction, the user is also relieved when exiting and he does not have to first supply the seat mat 54 before he can pull his rollator out of the niche. In addition, the mechanism ensures that the seat mat 54 is again ready for the next use trouble-free.

Different types of mechanisms can be used. FIGS. 15 to 19 show a preferred variant. In Figure 15, the seat mat 54 is in its initial position. It is arranged completely in the housing 50 except for the head part 53, wherein it runs flat along a rear wall of the housing 50 and is guided in the upper part of the housing 50 via a deflection plate 500 to the slot.

In a lower region of the seat mat 54, a driver 542 is attached, which is also firmly connected to a cable 59 which passes through the driver 542. The rope 59 forms a self-contained band.

It extends from the driver 542 along the seat mat 54 up to below the baffle 500, where it is directed by means of a plurality of upper pulleys 590 to the side edge of the housing 50 and then again vertically downwards. The upper deflection rollers 590 are mounted on an upper horizontal axis 55, wherein the axis 55 is fixedly fixed in the housing 50. The cable 59 once revolves around the wheel 57, being guided in a corresponding groove on the circumference of the wheel 57. The cable 59 then leads to a lower axis 56 and lower pulleys 591 back to the driver 542th

In the center of the wheel 57, a scroll spring 58 is arranged, which is tensioned by rotation of the wheel 57 or rotates the wheel 57 in the direction of relaxation. An outer end of the scroll spring 58 is fixedly connected to the wheel 57 for this purpose. An inner end of the scroll spring 58 is held stationary in the housing. When pulling out the seat mat 54 thus the cable 59 is moved, the wheel 57 is rotated and the spring 58 tensioned. This can be seen by looking through FIGS. 15 to 17. Preferably, the wheel 57 rotates by approximately 140 °. Other angles of rotation are possible depending on the embodiment.

If the tensile force on the seat mat 54 is removed, the seat mat 54 is thus pulled back into the housing 50 due to the relaxation of the spring 58 by means of the cable 59. This does not happen while the Rollator user on the If you want to set pulled-Sitzmate 54, the device preferably has a time delay. This can in turn be realized in different ways.

FIGS. 15 to 19 show a preferred variant. In the wheel 57, a tension curve 581 is arranged, which forms a pitch circle whose distance to the circumference of the wheel 57 steadily decreases. The tension curve 581 is connected to the wheel 57, together with this pivotable and preferably in the radial direction to this movable. The tension curve 581 is connected via a return spring 582 with the outer end of the scroll spring 58. It runs with its inside when pulling out the seat mat 54 along a fixed tension roller 580, which is connected via a spring-loaded arm 583 in the center of the scroll spring 58 to the housing 50. This can be seen in FIGS. 13 to 17. The arm 583 and thus the tension roller 580 are thereby displaced against the force of the spring 584 to the wheel center.

If the seat mat is completely pulled out, as can be seen in FIG. 17, the tensioning cam 581 is below the tensioning roller 580. The tensioning roller 580 is thus released again. It pushes thanks to the partial relaxation of the spring 584 on the cocking curve 581 and thereby blocks a relaxation of the scroll spring 583 or a turning back of the wheel 57. The further relaxation of the spring 584 takes place with a time delay, including known, for example, hydraulic or pneumatic means are used , These means are preferably arranged inside the arm 583. The idler 580 is slowly pushed to the periphery of the wheel 58 until it is on the outside of the cam 581 and thus releases them again. This can be seen in FIG.

In the absence of load on the seat mat 54 or in the absence of tension on the seat mat 54 from the outside and released tension roller 580 according to Figure 18, the scroll spring 58 can relax again. Since the scroll spring 58 acts between the wheel 57 and the housing 50, the wheel 57 moves together with the cam 581 counterclockwise back to the starting position. The tension roller 580 remains on the outside of the tensioning curve 581 (see FIG. 19) until it releases it again. This end position, which corresponds to the initial position, is shown in FIG. The tension roller 580 together with the delay mechanism arranged in the arm 583 and the spring 584 forms a mechanical timer or a mechanical interrupt or delay unit. This is determined by the hold-open time, ie the time before the mat is retracted again. During this time of driving over the seat mat is blocked and will not be retracted. The user can use this time for sitting down.

FIGS. 20 to 35 show a fourth embodiment of the invention. Identical parts are provided with the same reference numerals as in the examples described above and will not be described again in detail here.

The rollator securing unit 6 in turn has a housing 60 in which a flexible seat mat 64 is arranged. The housing 60 is wider compared to the previous example, but designed to be lower. The seat mat 64 preferably consists of mat members 641 which are connected to one another and which can be bent relative to one another via bending axes 640. The seat mat 64 is wound on a roll 7 (see FIG. 24) in the housing 60. From the housing 60 protrudes the free end of the seat mat 64, which is formed by a rigid head portion 63 which is provided with a handle 62 or formed as a handle. The seat mat 64 is preferably made of plastic.

In FIGS. 20 to 23, the seat mat 63 is shown in various pull-out positions. In Figure 20, it is completely retracted into the housing 60. In FIGS. 21 and 22, it is pulled over the seating surface 30 of the rollator 3 until, according to FIG. 23, it extends completely over the seating surface 30 and is bent in the region of the free end. As in the previous example, the user can now sit on the seat mat 64, whereby he simultaneously secures his rollator in the vehicle.

In Figures 24 and 25, the seat mat 64 is shown in the wound state. It is arranged in the housing 60, now shown in dashed lines. The already mentioned roller 7 extends over the width of the housing 60 and is pivotally or rotatably mounted in this on both sides. A roller axle mounted in the housing 60 is provided with the reference numeral 70. The restoring or winding mechanism has at each end of the Roll 7 a headboard 65, 66 on.

The first head part 65 has (see Figure 26) has a transmission with two gears. A first gear 654 with an external toothing is fixedly connected to the roller axis 70. A larger second gear 655 with an external toothing is rotatable about a first bearing 656 and engages the first gear 654. A cylindrical base body 650 of the first head part 65 is also firmly connected to the roller axis 70.

On the main body 650 a radially projecting resilient switch 651, a partially extending over the circumference partition 652 and a first stop 653 are present.

The second gear 655 has a part-circular slot 657, in which engages a second stop 659 in the form of a bolt. The second stop 659 is fixedly arranged on the housing 60.

The diameters of the two gears 654, 655 are sized such that multiple rotation of the first gear 655 allows only a rotation of less than 360 °, preferably 270 °, of the second gear 655.

The resilient switch 651 is attached to one end of the partition wall 652 and extends over part of the circumference of the base body 650. Below the freely movable end of the resilient switch 651 is the first stop 653 in the form of a block arranged on the circumference of the base 650 with a curved arranged lower surface. Spaced below the ends of the partition 652 facing the switch 651 ends with an end face 652 'directed towards the first stop 653 (see FIG. 29).

The second head portion 66 has, as well seen in Figure 24, a gear with a fourth and a fifth gear 660, 661 and a scroll spring 663 with an outer end 664 and an inner end 665 on. The outer end 664 is fixed to the housing 60, the inner end 665 to the roller axis 70.

The fifth gear 661 is connected to the housing 60 by means of a first fastening plate 662 attached. The larger fourth gear 660 is mounted on the roller axle 70. This braking mechanism is preferably increased by means of at least one brake disk, preferably made of a plastic, which inhibit the movement of the fourth and / or fifth gear 660, 661.

Further, a deceleration mechanism 67 with a pivot lever 670, a coil spring 68 and a rod 69 is provided. The pivot lever 670 is pivotally mounted on a pivot axis 671 on the housing 60. It has a first arm with a protruding catch 672. The driver 672 is directed towards the main body 650 of the first head part 65. The driver 672 is formed in this embodiment as a bolt.

The pivot lever 670 has a second arm, which forms a toothed ring 674 on one end face. On the housing 60, a sixth gear 676 is fixed, preferably by means of the second mounting plate 675 shown in the figures. The sixth gear 676 engages the toothed ring gear 674.

The rod 69 is held at the opposite end in the longitudinal direction in a recess of a receptacle of the housing 60. For this purpose, a lock nut 690 is provided. The recess and the receptacle are not shown in the figures.

One end of the seat mat 64 is fixed to the roller 7. If the seat mat 64 unwound, so that is connected to the roller 7 first gear 654 is rotated. This drives the second gear 654, which rotates about the first bearing 656. This is clearly visible in FIG.

At the same time, the second head part 66 also rotates on the opposite side of the Roll 7 with. The scroll spring 663 is tensioned. This can be seen in FIG.

FIGS. 26 to 35 show how the manual withdrawal and the automatic resetting of the seat mat 64 take place. The automatic reset preferably takes place only after a time delay. In addition, the winding movement is braked and slowed down accordingly. This will be explained below. The direction of movement of the seat mat 64 is shown in the figures on the left side of the figures, each with thick gray arrows.

In Figure 26, the seat mat 64 is fully wound and thus in its home position. The scroll spring 663 is relaxed and the driver 672 is located below the resilient flap 651. The second stop 659 is located at a first end of the slot 657th

Now, if the seat mat 64 is pulled out of the housing 60 for use, then the roll axis 70, the first gear 654 and with the two head parts 65 and 66 rotate in the same direction.

On the one hand by the scroll spring 663 is stretched.

On the other hand, the second gear 655 also rotates and the main body 650 moves along a path A, here referred to as the standard path, relative to the driver 672. By comparing FIGS. 26 and 27, it can be seen that the second gear 655 has rotated by approximately 90 ° while the body 650 has been rotated more than 360 °.

If the seat mat 64 is further pulled out, then the main body 650 now moves so that the driver 672 comes to lie on the inside of the resilient switch 651. The swing arm 670 is pivoted about the pivot axis 671, the fifth gear 676 winds along the sixth gear 676 and the coil spring 68 is tensioned. The mechanical timer is thereby charged. Instead of the standard track A, a secondary track B, which is separated from the standard track A by the dividing wall 672, is now used on the main body 650. This is clearly visible in FIG. In FIG. 29, a further rotation of the basic body 650 of almost 360 ° was carried out. The driver 672 is now at the first stop 653. The coil spring 68 is still stretched maximum. The second stop 659 is located at the second end of the slot 657 and thus prevents further rotation of the second gear 655. As a result, the roller 7 can not continue to rotate. The maximum extension position of the seat mat 64 is reached and further extension is prevented thanks to the second stop 659.

Now, the seat mat 64 is released, i. the externally applied force is removed, so prevents the first stop 653 together with the end face 652 'of the partition 652 a turning back of the main body 650 and thus the roller 7. The seat mat 64 remains even without external force in the extended position. This is shown in FIG.

Due to the restoring force of the spiral spring 68, however, the driver 672 along a guide 653 ', formed by the lower end face of the first stop 653, pulled in the direction of standard web A, as shown in Figure 31 can be seen. The train is enough to get on the standard train A.

Once this position has been reached, the base body 650 and thus the first gear 654 and the roller 7 can be rotated again. The seat mat 64 is retracted. In this case, the second gear 655 also rotates, so that the slot 657 also moves back to the starting position with respect to the second stop 659. This is shown in FIGS. 32 to 34. In Fig. 35, the home position is reached. The seat mat is fully retracted as shown in Figure 26 and ready for the next use.

This embodiment has the advantage that it can be made very compact.

The inventive Rollator security unit provides easy operation and a secure seat for the passenger and can also train cost and robust. REFERENCE LIST Interior equipment 5 Securing unit Vertical rod 50 Housing
