Abstract

The device foresees an overturned U-shaped tool for interposition and support, solidarily acting for the skis (19), consisting of two structures (1 and 5) centrally articulated with binding automatism, of which one (5) slides on guides (4) inside the other (1) through a synchronous action on the sides of gripping couples (2-3 and 6-7) with lateral outboaring. Of the said gripping pieces, the lower ones (6 and 7) are brought on the terminals of the sliding structure (5), whereas the upper ones (2 and 3) get out from the fixed structure (1). When the device is opened, helical retention springs (16) fitted in their seats (17) in the containment part (1) keep the sliding piece (5) in position enabling to put the skis (19) on the gripping parts (6 and 7) of the mobile structure (5). The activation of the control lever assembly (13), fitted on the upper part acting as handle when closed, raises the sliding structure (5) blocking the skis in solidarily operating condition.

Description

"Device for ski hand-transport".

The invention refers to a tool carrying out the compaction of the skis in their natural trimmed disposition, with solidarily opera¬ ting bound, controlled in synchronism and manually by means of an automatism, and is integrated with a central catching handle. The assembly can be lifted with only one hand when in balanced condi¬ tion.

To be rationally positioned and/or transported, the skis must be fitted together on their lower surface and bound together with a view to forming only one assembly with minimum encumbrance. The conventional procedure foresees their ends bound by means of straps. The operation can be carried out subsequently with the two hands and the assembly can then be transported on one shoulder. With this system, a precarious binding condition is carried out which compels to act with strips up to the limit of the clasp in¬ sertion. An uncomfortable condition thus results both on account of the assembly to carry as well as of the binding elements and of the loss of time. A further proceeding carries out the imprisonment by means of articulation elements, with intermediate disposition on the approached skis on their two lower surfaces. In this way, the binding stability is increased in ccmparison with the preceding sv stem, but deforming strains are generated on them since their na¬ tural trjjπning is changed. A further proceeding foresees the ac- comodation of the skis in purses: this system cannot be used on the snow fields as it increases the encn_m_bering volume in the transport phase.

The invention device obviates the above inconveniences by adopting a new conception means which realizes the acccxrrnodation in a soli¬ darily operating way and by maintaining the ski natural trirrmed po sition. The device can be promptly employed, transported even with only one hand and with positioned stability on a plane. Substantial¬ ly- a bridge type structure is employed which is available with in- terposition and supports the skis in composition on their sides in gripping pair of symmetric scheme line. The device consists of two centrally articulated structures with binding autαratism, of which one slides on guides in the inner space of the other for the syn¬ chronous drive of the said gripping parts outboarding on their si- des, and with retairάng tongues, the lower ones of which are mova¬ ble since their are a part of the sliding structure and act also as leaning feet of the tool on the plane; the upper ones, on the con¬ trary, belong to the fixed part and get out in correspondence with the containment structure. The binding automatism Θtroloys a through pin which retains the containment part and is hand-controlled by means of an excentric lever device contained between the sides of the upper length of the containment part. In this way, the higher part of the containment structure, when closed with the one of the relevant re-entered sliding part, forms a handgrip in the central upper position which enables to lift with one hand the tool in ba¬ lanced condition. When the tool is open, helical reta÷ining springs fitted in seats of the containment structure and beating on the i- nitial parts of the leaning bases on the mobile part gripping devi¬ ces, keep back the sliding structure on the lower limit. This allows to lay the composed skis into the binding seats on the leaning bases o mo e ar g pp ng , c e re a n ng ongues keep the whole in this condition. The control lever assembly, when activated, brings the sliding structure to return up to the supe¬ rior limit. This causes the ski blocking in solidarily operating condition, with the interposed supporting part acting as a dista ce piece.

Form of execution of a tool with containment and sliding structures in plastik materials is illustrated, in a merely indicative way, in the drawings of tables 1 and 2. With reference to them, fig. 1 ^' is the separated view of the tool components; in the higher side, the containment structure can be observed with the inside sliding guides, as well as the helical spring seats in the shoulders. The excenter lever device can be noted in the centre, and below the sliding structure bringing the articulation pivot on an intermedia¬ te higher length to which the above mentioned control organ can be bound. Fig. 2 is the front view of the opened device. Fig. 3 is the view of the same device as per the previous figure, but in block ed position of the ski pair, which can be seen in hatched execution. Fig. 4 is the perspective view of the tool in blocked condition as per previous drawings.

The bridge-shaped tool consists of two upset "U"-shaped ccmponents of which 1 is the containment structure with fixed gripping parts 2 and 3, and inside guides 4 for structure 5 sliding with gripping teπrάnals 6 and 7 of mobile part. The two structures are axially ar ticulated by pivto 8 in screw thread 9 of part 5, passing into bore 10 of part 1. This pivot 8, by means of pin 11 , passes above into excentric bore 12 of the control lever assembly 13, beating on the upper channel 14 of component 1 , which channel is contained between the sides 15 that prevent part 5 deranganent through unscrewing of the same pin 8 and integrate the said control lever system in the structure. With contrasted movement of the pair of helical sprincrs 16 fitted into seat 17 and beating on the initial part 18 of the leaning bases of the gripping parts 6 and 7, after having set the ski pair 19, it is possible to bring the whole assembly in block¬ ed position by activating the control lever system 13 by means of clockwise rotation. In blocked condition, the upper part of compo nents 1 and 5 which are outboarding from the skis, dete__mines a catching handle for hoitsting the whole assembly. By regulating the pivot 8 in threading 9 of part 5, the device can be suited to the width of the skis to bear. This can be carried out by means of the control lever assembly 13. In order to obtain an additional retaining effect, the gripping parts are fitted with containment tangs 20.

The components, arrangαnent and n___ber of the gripping parts, as well as the ret_a__ning means and materials, may be foreseen in dif¬ ferent ways.

Claims

.

1) Device for ski hand-transport, characterized by the fact that a bridge-shaped structure available with interposition and which sup ports the skis in side composition (19) in pair of line gripping parts (2 - 3 and 6 - 7) , is used. The toll consists of two structu re (1 and 5) centrally articulated with binding autcmatism, of which one (5) glides on guides (4) in the inside space of the other (1) , by means of the synchronous activation of the said gripping parts which have outboarding sides and retaining wings. Of the abo- ve gripping parts, the lower ones (6 and 7) are mobile since they are parts of the sliding structure (5) and act also as leaning foot of the tool on the plane, whereas the upper ones (2 and 3) of fix¬ ed part (1) get out in correspondence to the containment structure. The binding automatism employs a passing pivot (8) , which holds back the containment part (1) , and can be controlled by hand through an excentric lever system enclosed between the sides of the upper con¬ tainment structure (1) . In enclosed position, the higher part of the containment structure (1), along with the one of the relevant reentered slidind part (5) , forms a handle in upper central posi- tion which enables to raise the tool. When the tool is open, retain ing helical springs ( 6) fitted in seats (17) of the containment structure (1) and beating on the initial parts (18) of the leaning bases on the mobile part (5) , hold the sliding structure on the low¬ er limit. This allows to lay the skis (1 ) into the binding seats on the lea ng bases of the gripping parts (6 and ) of the mobile section (5) since the whole assembly kept in this condition in fur¬ ther assured by the retaining wings. The control lever assembly (13) , when activated, brings the sliding structure (5) back to re-enter up to the higher limit: this determines the ski (19) blocking in mutual. ly solidarily operating condition with the supporing interposed part acting as distance piece.

2) Device for ski hand-trasport, as per claim 1, characterized by mobile part (5) , it is possible to suit the tool to the width of the skis to carry. This can be acccmplished by means of the control lever assembly (13) .

3) Device for ski hand-transport, as per claim 1, characterized by the fact that in order to obtain an additional retention effect, the gripping parts (2 - 3 and 6 - 7) are fitted with containment wings.
