Description

The present invention relates to a device holder for clamping of handle devices under gravity according to the preamble of claim 1.

Device holders are needed for hanging work equipment, preferably those with a handle, and should be as easy to operate, preferably by the suspended work tool itself without the help of a hand of an operator. It is known to use this gravity, on the one hand facilitates the closing of the device holder to hold the implement as well as the holding force applies.

Such a device holder is from the EP 0 180 884 B2 known, which discloses a device holder according to the preamble of claim 1. He has a fastened to a wall clamp carrier and a reversible to this from a horizontally closed to a vertically open position pivotable clamping shears. The clamping shears consists of two scissor arms, which are each rotatably mounted in the clamp carrier with an angled clamp carrier side end, the free legs cross each other and define a device receptacle between them. The closing movement of this known device holder is limited by a sliding ring around both scissor legs at the intersection. A disadvantage of this prior art is that the crossing scissor legs lie in an inclined plane, so that hinged tools experienced by the vertically spaced contact points of the scissor legs on the implement a force that swings them laterally and thus can hang crooked in the device holder. This facilitates falling out of the tools from the holder and leads to a non-secure suspension. At the same time would be an opening Damage of the ring lead to a uselessness of this known device holder, since the scissor legs could then swing past each other. Finally, it can also lead to a jamming of the ring and scissor legs, which can be unusable the known device holder.

From the DE 20 2006 009 550 U1 Therefore, a device holder for clamping of handle devices under gravity is known, in which the scissor legs are guided vertically by means of a link in the clamping part and their closing downward movement is limited by a stop. In this known device holder, the scissor legs lie in a horizontal plane and do not cross each other. The simultaneous movement of both scissor legs is enforced by a spacer placed between them and guiding them. If this is damaged, proper functioning of the device holder is no longer possible because the scissor legs are movable separately, so that when hanging a hand must be taken to the rescue. At the same time, the terminal part side stop can be knocked out for prolonged use by heavy equipment.

It is therefore an object of the present invention to provide a device holder that holds the devices safely and remains functional for a long time.

This object is achieved in that the scissor legs in the field of device recording are always in a plane whose cutting line is aligned horizontally with the clamping carrier plane and that at least one scissor leg is at least the pivotal movement of the other scissor leg in the clamping position by means of a stop limiting. If the scissor legs in the area of the device receptacle always lie in a plane whose cutting line is aligned horizontally with the clamping carrier plane, it is advantageous ensures that the scissor legs are in the clamping state parallel to each other and in an approximately horizontal plane. As a result, a clamped between them device is held without torque, so that it hangs straight, not swing away sideways and thus can not easily slip out of the clamp. This advantage of the invention over the prior art is further enhanced by the fact that according to the invention the scissor legs are used to mutually guide and limit the pivoting movement. As a result, an additional component as required in the prior art can advantageously be dispensed with, on the one hand, and on the other hand, the clamping support can be simplified structurally and does not have to fulfill any further functions. According to the invention, at least one pair of scissors should limit the pivotal movement of the other by means of a stop, of course, a mutual restriction is conceivable. According to the invention, the stop can be designed in any desired form, for example as a patch stop or molded stop lug, as a flank, through surface profiling or the like.

In an embodiment of the invention, it is provided that at least one scissor leg is a movement link for the other scissor leg, in particular has a cranked portion. With great advantage, this configuration causes the second leg is more or less forcibly guided by the first and thus can change its relative position to the first scissor limb only difficult, which promotes the safety of the clamping. An embodiment of this Bewegungsungskulisse is according to the invention a cranked portion, in the cranking of the other leg of the scissors is guided and on whose flanks he finds a movement-limiting stop.

With particular advantage, the invention provides that the free legs of the clamping shears are formed penetrating. In this case, according to the invention, in particular a penetration of the mutual position levels of the scissor legs and less a material penetration meant. This penetration is achieved, in particular, by one or both scissor legs having a portion bent away from the other scissor leg.

A particularly simple but effective embodiment of the invention is that in which a clamping shear has a slot through which the second clamping shears passes. Such a slot is easy to produce and provides a completely enclosed gate path, so that the second pair of scissors can escape from their forced operation only after material breakage. The walls on the narrow sides of the oblong hole form the stops that limit the path of movement of the guided in the slot Scherenschenkels.

If the oblong hole is formed by a long-hole cuff made of plastic or metal, which is inserted in the scissor leg, a simple production path is advantageously indicated. The connection of the separately produced oblong sleeve with the scissor limb can be effected according to the invention by gluing, welding, clipping, screwing or riveting. In the case of screwing would be provided on the scissor leg an external thread, complementary to an internal thread in the slot cuff.

Particularly simple is the embodiment in which the slot is introduced into the material of the scissor leg, for example, by slotting the same.

In an embodiment of the invention it is provided that the clamping shears is pivotable against a counter force in the open position. Such Counterforce prevents the clamping shear remains in the open, vertical state and must be triggered by hand to move to the clamping position. In addition, such an opposing force increases the gravitational clamping force and thus contributes to an even safer mounting of the clamped devices.

If the counteracting force acts on at least one clip carrier-side end of the scissor legs, the lever is minimal, but the structural integration in the device holder is simplified since it can be arranged in the clamping carrier.

Advantageously, the invention provides that the counterforce is a torsional force or acting on a arranged on a clamping carrier end end actuating surface spring force. A torsional force could be generated for example by the design of the implementation of the ends in the terminal carrier or by the provision of a bending spring. On the other hand, a spring force on an actuating surface is particularly easy to implement because a simple coil spring can be used, for example, be supported on a pin penetrating her eye and loosely bear against the actuating surface with its free end, wherein the actuating surface with the clamp carrier end of a scissor leg connected is.

It is particularly advantageous that the clamping carrier according to the invention has a fastening-side profiling for a wall system or a profile system. As a result, it can either be arranged directly on a wall if it has a flat rear side or be held in a profile if it has a rear side matched to the profile. This can, for example, according to the DE 10 2008 006 439.4 be designed.

The invention will be described by way of example in a preferred embodiment with reference to a drawing, wherein further advantageous details are shown in the figures of the drawing.

Functionally identical parts are provided with the same reference numerals.

FIG. 1 schematically shows a perspective front view of an embodiment of the device holder according to the invention. Good to see is the terminal support 1, which is to be attached in this embodiment to a wall. For this serve through holes 15 which are penetrated by fasteners such as screws. The embodiment of the invention further comprises a clamping shear 2, formed by a first scissor leg 3 and a second scissor leg 4. These scissor legs have a diameter of 6 mm and are made of metal. Both scissor legs each have a clamp carrier side end, which is received and held in the interior of the clamp carrier 1. They continue to instruct free end, which forms the device holder 9. The first scissor leg 3 has a first free end 7 and the second scissor leg a second free end 8. Both free ends 7, 8 are respectively corresponding to each other and bent away from each other. You can like in FIG. 1 shown, a rubber coating 16, which increases the static friction to a non-illustrated salaried device, so that it is held stronger and safer. The two scissor legs 3 and 4 lie in a common plane, which in the illustrated horizontal clamping position of the clamping shear 2 has a straight line with the mounting plane of the clamp carrier 1, which is strictly aligned horizontally. This is particularly important according to the invention in order to generate no torque generating, horizontally offset points of attack of the free ends 7 and 8 on the non-illustrated content Erten device. The clamping shears 2 can be pivoted from the illustrated horizontal clamping position vertically upward into an open position. In this case, the position of the second scissor leg 4 to the first scissor leg 3 changes. In the illustrated clamping position, the second scissor leg 4 abuts against a stop 10, which is formed by the inner wall of the front narrow side of the elongated hole 12. The slot 12 is simultaneously a Bewegungsungskulisse for the second scissor leg 4, wherein the movement end positions is formed by the front stop 10 in the clamping position and the rear stop 10 'in the open position. The second scissor leg 4 is thus forcibly guided in the first scissor leg 3.

In FIG. 2 is shown schematically and in perspective a rear view of this embodiment, in which the rear stop 10 'can be seen better. Likewise conceivable according to the invention would be an embodiment in which the upper long side of the oblong hole 12 is missing, so that instead a downwardly cranked section 11 would result. In this second scissor leg 4 would still be forcibly guided. He would find on the narrow sides also a front stop 10 and a rear stop 10 'before. In this embodiment, it would also be conceivable to provide the second scissor leg 4 with a second cranked portion 11, which would result in movement of the clamping shears in the open position to a stop for the first scissor leg 3, as in position of both legs 3, 4 to each other during the movement changes. On the back of the clamp carrier 1 to recognize the attachment-side profiling 14, which is a flat surface in this embodiment. Good to see are also the passage holes 15 to the passage for fastening means, not shown. Evident are the clamp carrier side ends 5 and 6 of the two scissor legs 3 and 4, which pass through the housing and are supported in the respective opposite housing wall. Evident is a retaining ring 17 which is pulled over the clamping carrier-side end 6 of the second scissor leg 4 and prevents axial displacement of the clamping carrier-side end 6. Shown is also attached to this end actuating surface 13, under which a coil spring 18 is located.

This is in FIG. 3 which shows a schematic side view in cut form. The actuating surface 13 is arranged on the clamp carrier end 6. The housing 1 and the actuating surface 13 have mutually facing lugs 19 and 20, between which a helical spring 18 is arranged. The lugs 19, 20 penetrate into the respective eye of the coil spring 18. During the pivoting movement from the illustrated clamping position upwards into the open position, the actuating surface 13 is thereby moved toward the clamping carrier housing 1, and the helical spring 18 is tensioned with it. The opposing force generated thereby causes the device according to the invention in the rest position always the clamping shears. 2 in the clamping position has. With great advantage, the invention prevents thereby that the clamping shears 2 or one of their scissor legs 3, 4 remain in the open position and thus an operator must take a hand to help.

In the last FIG. 4 is shown schematically in perspective rear view of a second embodiment of a clamp support 1 according to the invention. This embodiment differs from the one described above primarily by the configuration of the fastening-side profiling 14. This is designed here so that it can be received in a profile, and has a corresponding counter-profiling 21. This consists of a sliding block 23 and two mutually parallel and horizontally spaced support planes 22 and a curved rear wall portion 24. Of course, according to the invention, any other profiling 21 is conceivable.
