Definitions
- TITLE TELESCOPE STAND FOR CARRYING OF ITEMS AND TOOLS.
- the present invention relates to a telescope stand for carrying items and tools, primarily for use and handling of a sanding tool during the sanding of ceiling surfaces and walls and comprising a base with a number of radial protruding wheel borne stands, in the middle of which is a center tube comprising a bush for receiving a telescopic column vertically upstanding from the base, comprising an outer tube and inside this, at least one inner axially displaceable telescopic tube, and where the free end of the inner telescopic tube comprises an U-shaped bracket with at least one horizontally oriented shaft by which the tool is tilt-able attached.
- DEU 831 1080 U1 discloses a wheel borne telescopic stand comprising a sanding tool with a basis, a number of wheel borne supports in the mid- die of which is a center tube with a bush comprising an outer tube and an inner telescopic tube with a U-shaped bracket in the free end of the tube in which the sanding tool is tilt-able rested via a pair of horizontally oriented stud shafts.
- Said stand enables tilting of the sanding tool during operation, but leaves certain features concerning freedom of movement.
- hand held/portable machines are used for process- ing items. Certain types of these machines is relatively heavy, and physically demanding for a person to handle and operate, often resulting in limitations in which persons who are able to handle said machines, due to lack of physical strength, and further attrition of those persons who have the necessary strength to operate with said machines.
- the reason for said attrition is the combination of a relatively heavy burden of the weight of the tool, combined with economically awkward working positions. It is the object by the invention to provide a stand, which enables that a larger group of persons are able to perform work with heavy machines in awkward working positions, which thus reduces the risk of attrition of the persons, which perform such tasks.
- the upper free end of the telescopic column comprises a vertically oriented stud shaft, to which the U-shaped bracket is pivotally mounted and upstanding from the free end of the telescopic column, said U-shaped bracket being connected, via horizontally hinge pin connections, to the first part of a pivotally mounted, dismountable, two- or multiple partitioned hinge bracket with clamping means for clamping of a tool preferably a sanding tool.
- giraffe sanders which is mostly used by house painter for sanding wall- and ceiling surfaces.
- the construction of the giraffe sanders are made to minimize the weight of these, shows he weight of these, however, yet to be a not inconsiderable in connection with its use. Therefore, it is mostly persons who have the sufficient physically strength, which perform said sanding work with said tool, and this often holds the female group of house painters to perform sanding work with a giraffe sander.
- a giraffe sander can be mounted in the hinge bracket in a manner that it approximately is balanced in the suspension point of the hinge bracket. This means that the user shall not carry the sander, which is rested in the pivotally and tilt-able mounted hinge bracket, in an easy manner can be rotated and pivoted to all preferred positions, so that the sanding abrasive disc surface can process all surfaces on ceilings and walls.
- a further advantage by the stand according to the invention is thus, that since the user does not have to use energy carrying the sander, it can instead concentrate on steering the giraffe sanders abrasive disc, whereby a significant more su- perior performance of the sanding process is achieved.
- the inner- and the outer telescope tube is interconnected with a fall lock, said fall lock being so designed, that it further coun- teracts relative circumferential displacements between the inner telescope tube and the outer telescope tube in the locked position of the fall lock.
- the sander can be displaced to, and be maintained in an optional position, thanks to the telescope tube.
- the fall lock is further designed so that it does not block for upward displacements of the telescope tube.
- the fall lock will have to be released, if downwards displacements of the telescope tube shall be performed, and thus the hinge bracket to a lower positioned working position.
- a shock absorber can be arranged inside the outer tube.
- the shock absorber may advantageously consist of an air-filled space with a piston and a pressure relief valve on the pressure side.
- the load of the tool carried in the hinge bracket will due to the gravitational force generate a pressure behind the piston, which pressure will be compensated through the valve, which typically only consists of a small hole on the pressure side, whereby the pressurized air behind the piston, during the downwards displacement of the telescope tube, will act as a resilient air cushion, the extent of which will decrease as the pressure is compensated through the valve, whereby the hinge bracket and the load/tool arranged therein, is displaced downwards.
- the pressure relief valve can be adjustable.
- a tilt-lock for locking the hinge bracket in a preferred position may be arranged between the U-shaped bracket and the hinge bracket.
- the against the base oriented side of the part of the hinge bracket connected with the U-shaped bracket can comprise a detachable operation rod, whose parts are interrelated with detachable locking means, said operation rod comprising a pivotally and length displaceable mounted folded/turned handle, which is essentially parallel to the operation rod.
- the handle can be turned and displaced around its length axis, and thus allows for a high degree of individual adjustment options for the user of the stand with a therein inserted tool, e.g. a giraffe sander.
- the outer tube of the telescope column may comprise a wall sanding bracket/parking bracket, consisting of a pivotally mounted pipe section arranged on the outside of the outer tube and comprising a from said pipe section protruding party, the free end of which comprises a vertically oriented tube section for receiving a stud shaft in the bottom of the U-shaped bracket with the clamp-able hinge bracket.
- the combination of the hinge bracket and the wall sanding bracket/parking bracket provides for an easier mounting procedure for the sanding tool in the hinge bracket, when the hinge bracket is locked in a given position using the tilt lock.
- the wall sanding bracket/parking bracket can comprise a fall lock which locks the wall sanding bracket/parking bracket against downwards oriented displacements, said fall lock being designed in a manner that it further counteracts circumferential displacements of the wall sanding bracket/parking bracket around the outer periphery of the outer telescope tube, in the locked position of the fall lock.
- the wall sanding bracket/parking bracket can be arranged in a preferred working level, or parking level. It should be noticed that the fall lock is de- signed in a manner that it does not lock against, or block upwards directed relative displacements between the inner and the outer tube.
- the support legs may be borne by swivel wheels, causing the execu- tion of a change in direction of movement of the stand easy to implement.
- At least one of the swivel wheels can be provided with a brake.

- Fig. 1 1 show a displaceable lock for arranging on the outside telescope tube for retaining of a vessel arranged on the carrying console shown in Fig. 10 and Fig. 2.
- a first embodiment of a telescopic stand 2 according to the present invention is shown in Fig. 1 and Fig. 2.
- the telescope stand 2 comprises a basis 4 with radial outstanding organs 6, the free end of which, are borne on swivel wheels 8, which can be lockable.
- I the center of basis 4 is a center tube 10 in which is inserted a vertically oriented telescopic column 12.
- the vertically oriented telescopic column 12 comprises in the shown embodiment of the telescope stand 12 an outer tube 14 and inside this an inner tube 16, which is carried on the outer tube 14 by a first fall lock 18.
- the upper free end 20 of the telescope column comprises an U-shaped bracket 22, which via a not shown vertical oriented stud shaft is pivotally mounted in and upstanding from the first free end 20 of the telescopic column 12.
- the U-shaped bracket 22 is via horizontally oriented hinge stud connections
- a tool which in the shown embodiment of the telescope stand 2 consists of a sanding tool, more specific a giraffe sander 32.
- a detail section of the fall lock 18 in locked position which encloses the inner telescope tube 16.
- the fall lock consists of tree parts, an angle bent perforated plate 34 which encloses the inner telescope tube 16, a therewith related mainly parallel displaced part 36 which is hinged to the first end 35 of the angle bent perforated plate 34 and a tightened spring 38 between the angle bent perforated plate 34 and the parallel displaced part 36, anchored in suited openings 40 in said parts 36, 34.
- the free end 37 of the mainly parallel displaced part 36 is attached to the outer telescope tube 14 as it appears from Fig. 1 , Fig. 4b, Fig. 5b and fig. 6a.
- the opposite end 42 of the angled perforated plate 34 is bent in the direction of basis 4 and forms an operating grip for releasing the fall lock 18.
- Fig. 4a which is an overview of the fall lock in unlocked position
- Fig. 4b which is a side view of the same, is shown how the inner telescope tube 16 are free to be displaced inside the outer telescope tube 14.
- the hole 46 in the perforated plate is not circular but oval or elliptic, which in combination with the angle bend 44 result in, that all pres- sure points /attack points between the outer surface of the inner tube becomes oblique, and thereby aggressive in a manner that all attack points will cut itself into the surface on the inner tube 16, which results in that the fall lock will be more efficient, and as a further advantage is achieved that relative turns between the inner tube 16 and the outer tube 14 are prevented efficiently.
- Fig. 5a and Fig. 5b are analogous illustrations with the illustrations in Fig. 4a and Fig. 4b but with the difference that the fall lock 18 is shown in locked position.
- Fig. 5a it is shown how the fall lock 18 in the shown embodiment is locking the inner tube 16 in 3 points against relative displacements, namely in the pressure points 48, 50 opposite the operation grip 42 and in the pressure point 52 at the same side as the operation grip 42.
- Fig. 6a and Fig. 6b which is respectively a perspective view of the fall lock shown in fig. 5a and fig. 5b, but seen from an oblique angle from below, and from below, but in locked position, the attack points 48, 50, 52 on the outside of tube 16 appears clearly.
- the angle bend 44 of the perforated plate 34 results in that the pressure points 48, 50 forms an angle with the pressure point 52, thus all the pressure points becomes oblique relative to the outer surface of the tube 16, which results in that it will be the edges of the hole 46, which attacks the outer side of the tube 16, and the pressure points 48, 50, 52 of the perforated plate will thus function as shares which aggressively will attack the outside surface of the tube.
- Fig. 7 is a perspective section of the outer telescope tube 14 with a mounted wall sand bracket/parking bracket 54
- Fig. 8 is a side view of the same in locked position.
- the wall sander bracket/parking bracket 54 consists of a pipe section 56 lo- cated above the outer telescope tube 14, said pipe section 56 comprising a mainly radial protruding plate 58 in the free end 60 of which is a vertically oriented tube section 61 for the receive of a stud shaft on the U-shaped bracket carrying the hinge bracket 30.
- the tube section 56 which is displaceable rested on the outer telescope tube, comprises a fall lock 62 anchored in the downward turning side of the plate 58.
- the fall lock 62 comprises tree parts, a connection piece 64 to the plate 58, a thereto connected plate 66 with an angle bend 67 comprising a hole for the receiving the outer telescope tube 14, and a not shown spring between the plate 58 and the angle bent plate 66.
- the angle bent plate 66 comprises a blunt downward protruding end 68 below the plate 58, which is used as operation grip for releasing the fall lock.
- the plate 58 is designed with a downward slope 59 to maintain maximum freedom of movement of the sander, if it in function is turned completely into the tube 56.
- both fall locks 18, 62 is, that they does not lock by an upwards displacement of the inner telescope tube 16 and the tube section 16 respectively, but they lock by a downwards movement and load.
- Fig. 9 is a section view of basis 4 of the telescope stand shown in Fig. 1 , showing an embodiment of an integrated fall damper 70.
- the fall damper 70 which operates after the similar principle as a bicycle pump, comprises a leather piston 72 located in the lower end of the inner telescope tube 16, an above the leather piston arranged guide piston 74 for guiding of the displacement of the inner telescope tube inside the outer telescope tube 14, a pin 76 for bottom stop, and a air dispenser- and support ring 78 between the pin and the leather piston 72, a bottom stop hole-disc 80 located in a bottom plug 82 with an air compensating hole 81 and an outlet hole 84.
- Fig. 9 shows the inside telescope tube 16 during displacement downwards, with the fall damper 70 in action.
- the leather piston 72 function as a bicycle pump and compress the air inside the cavity 15 inside the outer telescope tube 14.
- the air in the air in the cavity 15, in front of the piston 72 is pressed out through the hole in the hole-disc 80 and further out through the air compressing hole 81 and the outlet hole 84 in the bottom plug 82.
- the velocity with which the inner telescope tube 16 is displaced inside the outer telescope tube 14, depends partly on the size of the air compensating hole 81 in the bottom plug 82, and partly of the size of the downwards directed force on the inner telescope tube 16.
- the leather piston 72 is drawn away from the guide piston 74 and is supported on the air dispenser- and support ring 78 whereby air can pass the guide piston 74 and the leather piston 72 into the tube 14, so that a vacuum in the tube 14 is not generated during an upwards displacement of the inner telescope tube 16, and the tube 16 can accordingly easily be displaced upwards.
- Fig. 10 is a perspective picture of a support console 86, shown in fig. 2, de- signed for mounting on the supports 6 on basis 4.
- the support console comprises a bent plate 88, the end of which are connected with upside-down turned U- shaped consoles 90, 92 which are mutually rotated in a suitable angle to fit on the supports 6 on basis 4, as it appears from Fig. 2.
- the support console 86 is eyed for arranging a vessel or a bucket (not shown), e.g. for accumulation of sanding dust from the giraffe sander 32.
- Fig. 11 shows a displaceable lock 94 for mounting on the outer telescope tube 14, cf. Fig. 2.
- the displaceable lock comprises a displaceable tube 96 on the outside telescope tube 14, which has an downwards oblique part 98 which can be brought in engagement with the rim of a vessel or bucket (not shown) arranged on the support console 86, so that the vessel or bucket is retained on the support console when the telescope stand is in operation.
- the telescope stand comprise an operation grip 100 for operation/control of the motions of the hinge bracket 30.
- the operation grip comprises a first operation rod 102 connected to the against the basis 4 oriented side of the first part 26 of the hinge bracket 30, and a thereto con- nected dismountable second operation rod 104, the parts of which are mutually connected by releasable locking means 106, 108.
- the second operation rod comprises further a pivotally mounted turned handle 110, extending mainly parallel with the operation rod and the second operation rod 104.
- the length of the operation grip 100 is adjustable, as the distance between the handle 110 and the first operation rod 102 is variable according to the telescope principle, which allows for operation with the sanding tool arranged in the hinge bracket in optional operation heights.
- the handle 110 is further pivotally mounted to the second operation rod 104, to allow an optional working position for the operator.
- the inventor has realized that the invention can adopt other embodiments than the one stated in the previous and shown in the drawing.
- Par example could one or more of the swivel wheels on the supports on basis be replaced by fixedly wheels, likewise one or more of the wheels, or all, might be supplied with brakes.
- the fall damper might be constructed according to other principles than air, e.g. it could consist of a hydraulic- or gas influenced piston.
- telescope tubes might be constructed of other than the shown cular steel tubes, e.g. square or hexagonal steel tubes.
- the material might e.g. consist of aluminum, plastic, glass fiber or carbon fiber. The fall lock and fall damper will easily adapt these materials.
