The utility model content
At this problem, the present invention redesigns and transforms known towel rack, so that downward can not cause above-mentioned reversing when powerful and cause unexpected distortion running into.
The problems referred to above of towel rack will solve by the feature of describing in the claim 1 according to the upperseat concept of claim 1.
Importantly to recognize, between support member and base, have a friction traditionally and connect (kraftschl ü ssigen verbindung), especially because of the big gravity that may bring than the long lever arm of force and people due to the towel bar length, thereby it is destroyed to cause this friction connection to be easy to, so that cause the joint of towel bar that top said reversing taken place.
The present invention proposes to connect to substitute the just connection of friction connection between connector and the base with one in the form fit on the rotation direction, thereby the form fit only by corresponding interface at least one part of connector and the base effectively prevents to rotate, even can there not be to realize under the big change situation effectively to prevent to be connected the rotation of the connector of base at material specification and production cost.If support member does not rotate, then towel rack also can bear the strong gravity of certain limit and it is transferred to metope.
First-selected especially design according to claim 2 can predefine particularly advantageously be distributed to energy flux on each element of towel rack, and this point meets " screw rule ".
By different designs to each section of connector, according to the first-selected especially design of claim 5 can realize separately independently, rotation direction with axially on can both carry out form fit with connector and be connected.
First-selected especially design according to claim 6 and 7 will be used a special pad, and it produces a pulling force by being threaded to connector, and applies a thrust via base to the sleeve that links to each other with support member equally simultaneously.So just guaranteed when support member is stressed, can be locked within the towel rack by momentum.
By according to a first-selected especially design of claim 12 can with at least one Lian Jie – of connector promptly and the Lian Jie – between the support member design firmly especially, for example pass through welding manner.
The specific embodiment
The towel rack of being described among the figure has two towel bar 1a, 1b.But it also can have arbitrarily many towel bar 1a, and 1b comprises only having unique towel bar 1a, a 1b.Towel rack can also have other peg except towel bar 1a outside the 1b, for example the rocking arm of a mirror or suchlike peg.
As describing among Fig. 1 a, b, the c, towel rack comprises a support member 1, on have an overhanging connector 2.Support member 1 is designed to support one or more towel bar 1a that are fixed on the support member 1,1b.Connector 2 has one threaded terminal 3.The end 3 of connector 2 has following characteristics, and promptly it is away from that end of support member 1 on the connector 2.
Towel rack also comprises a base 4 in addition, has one to be used for the opening 5 that connector 2 stretches on it.Base 4 is a cover plate that certain depth is arranged basically, it around and shelter from the installation position of towel rack at metope.Pay the utmost attention to the middle part of opening 5 designs at base 4.
Towel rack also comprise one at least with support member 1 and base 4 in one be the sleeve 6 that friction is connected.When that is to say between support member 1 and base 4 installing sleeve 6, be at least or sleeve 6 and support member 1 between or link to each other with the friction connected mode between sleeve 6 and the base 4.Therefore sleeve 6 neither can connect as one also with support member 1 and can not connect as one with base 4.Except covering connector 2, sleeve 6 can also become another energy transfer way except that connector 2 between base 4 and the support member 1.
Towel rack also comprises a counterpart 7 with the threads engaged of connector 2 in addition, and a spacing washer 8 that is placed between counterpart 7 and the base 4.
Importantly, the setting of counterpart 7 is in order to make the sleeve 6 between support member 1 and the base 4 generate the friction connection by spacing washer 8 and base 4.The friction here connects and is meant at least in existing friction between sleeve 6 and the support member 1 or between sleeve 6 and base 4 and connects.Equally also the very important point is, the setting of base 4 is in order to make antitorque the linking together in base and connector 2 form fit ground by the opening 5 that connector 2 is penetrated base 4.Base 4 just can not rotate around the axle of the connector 2 axially like this.
So, between base 4 and support member 1, form friction by counterpart 7 by sleeve 6 on the one hand and connect, prevented connector 2 slippage from the opening 5 of base 4.The form fit on rotation direction has prevented that base 4 from rotating between base 4 and the connector 2 on the other hand, has guaranteed also that thus the base 4 and the friction between the support member 1 that produce via sleeve 6 connect.According to this invention, two connections have guaranteed can not become flexible separately mutually.
The towel rack of describing among Fig. 1 a, 1b, 1c and Fig. 2 a, the 2b has a lot of favourable designs.As by at least with support member 1 and base 4 in a sleeve 6 that has friction to be connected apply a pressure, and connector 2 is in order to bear a pulling force between support member 1 and counterpart 7, at towel bar 1a, when 1b suffered external force, kinetic energy can be distributed in the towel rack better so.
The power that this power distribution mode in the towel rack also can be described as according to " screw rule " distributes.Be that the cork bottle opener has applied a pulling force by its helix to cork, and press to the bottleneck around stopper, the result who has caused cork to be drawn out thus.The connector 2 that is fixed together with support member 1 on the towel rack here moves, but acts on the pulling force on the inner member and be identical on principle to the pressure that acts on outer member.
, if the screw thread of counterpart 7 by connector 2 pulls to base 4 with it, promptly applied a pulling force here, can apply a pressure to spacing washer 8 simultaneously so, spacing washer 8 is passed to sleeve 6 by base 4 with this pressure again.The kinetic energy of 1 pulling force and pressure is distributed on connector 2 and the sleeve 6 thus well from counterpart 7 to support member.
Herein that fully independently sleeve is especially favourable, and it neither becomes one with other any elements, can predetermined fixed yet on what.According to this first-selected design of sleeve 6, sleeve 6 is used for accepting support member 1 like this, and all has friction to be connected with support member 1 and base 4 both sides.Because sleeve 6 encases connector 2 fully, it also can be transferred to the bending stress from any direction support member 1.If especially sleeve 6 is independently accessories, then it all is that friction connects with being connected of support member 1 or base 4.
Same spacing washer 8 is also paid the utmost attention to and is designed to counterpart 7 and base 4 all is to rub to be connected, and it also is designed to independently accessory so.
If there is one to separate with threaded terminal 3 and during a end that pattern is different, antitorque form fit connects and more can ensure between connector 2 and the base 4.In the favourable design of towel rack, connector 2 has a stage casing 9, connects and can produce antitorque form fit between the stage casing 9 of base 4 and connector 2.As depicted in figs. 1 and 2, stage casing 9 can or terminal 3 and support member 1 between whole one section, one or more other sections perhaps also can be set between stage casing 9 and support member 1.Also can be optionally or one or more other sections also are set between stage casing 9 and terminal 3 extraly.
Connector 2 just has two sections of separating respectively like this, and one is threaded terminal 3, is used for preventing that connector 2 is drawn out, and one is stage casing 9, rotates in order to prevent connector 2.
On the one hand in order to guarantee antitorque form fit, on the one hand in order to make connector 2 pass the opening 5 of base 4 fast and as far as possible easily, especially be fit to consider first-selected following proposal, be that to be designed to the cross section be polygonal in stage casing 9, the opening 5 of base 4 matches with the cross section in stage casing 9, and spacing washer contains a pad 8, has an opening 10 that allows stage casing 9 pass above.As shown in Fig. 1 and Fig. 2, the cross section in stage casing 9 can be a square cross section, and the opening of base 4 also should have a square cross section as shown in the figure mutually in this first-selected design.
The cross section in stage casing 9, and the opening 5 of corresponding base 4 and the opening 10 of pad 8 can be a triangle, rectangle or any one polygonal too, connects just so long as be adapted at forming on the rotation direction form fit.
According to " screw rule ", in order to make counterpart 7 produce pulling force by 8 pairs of connectors of pad 2, and simultaneously sleeve 6 is produced pressure, especially pay the utmost attention to end 3 and stage casing 9 direct neighbors, sleeve 6 is between base 4 and support member 1, connector 2 passes the opening 5 of base 4, and the length of sleeve 6 will just make the part in stage casing 9 stretch out away from that side of connector 2 from the opening 5 of base 4.Can be clear that the sight that stretch out in stage casing 9 especially among Fig. 1 b.
In this external this preferred option, the thickness of spacing washer or title pad 8 is greater than the part that stretch out in stage casing 9 from the opening 5 of base 4.In order to guarantee this point, the length of sleeve need less than from support member 1 to the stage casing distance, especially this difference 9 the end at least with the consistency of thickness of base 4 in its opening 5 zones.By pad 8 required minimum thickness, counterpart 7 can produce pressure to sleeve 6 via base 4.
Fig. 1 a, 1, the variant of being described among b, 1c and Fig. 2 a, the 2b also will be paid the utmost attention to especially, and wherein terminal 3 have an external screw thread, and counterpart comprises a tapped nut 7.As especially can be high-visible among Fig. 1 b, terminal 3 can be to be conical taper.
In order to make the pressure that acts on sleeve 6 is laterally or axially all to reach more uniformly to distribute, can pay the utmost attention to following scheme, the feature of this scheme is: support member 1 is for cylindric, and sleeve 6 also is cylindric, and its scarf 11 is just in time fitted with support member 1.The circular tangent plane of support member 1 must have rotational symmetry, and regardless of towel bar 1a, whether 1b reverses, and rib or angle can not occur on the support member 1 like this.Because the cross section of sleeve 6 also is circular, it has rotational symmetry, and scarf connects the friction between sleeve 6 and the support member 1 and can produce along the gamut of sleeve 6.
For each self energy of more than one towel bar that is fixed on the support member 1 is rotated separately, preferably support member 1 comprises at least two coaxial hinges 12,13.As depicted in figs. 1 and 2, all can fix a towel bar on each hinge.
What also give special priority in this embodiment is that connector 2 links to each other with support member 1 between at least two coaxial hinges 12,13 of support member 1.Reduced towel bar 1a by this assembling mode, the ultimate range between the tie point of 1b and the connector 2 can make that advantageously lever arm of force was shorter when towel bar 1a, 1b suffered downward greatly pressure.
It is rectangular with support member 1 to give special priority for connector 2 equally, connects, especially links to each other with support member 1 by welding by material.Then make connection firm especially and reliable by the material connection.
Installation process to the towel rack described among Fig. 1 a to 1c is described below.At first sleeve 6 is enclosed within on the connector 2.Connector 2 part of from sleeve 6, stretching out then, especially terminal 3 and the part in stage casing 9 pass the opening 5 of base 4, base 4 just is connected with the antitorque form fit of stage casing 9 formation of connector like this.
Pad 8 is enclosed within that section of the connector 2 that stretches out from the opening 5 of base 4, nut 7 is tightened on terminal 3 the external screw thread.So just connector 2 is produced a pulling force, produced a pressure by pad 8 and 4 pairs of sleeves of base simultaneously.
As Fig. 2 a, shown in the b, towel rack preferably has one with holes 15 mounting disc 14.Hole 15 is to be used for ordering screw and to form bolt connecting, promptly be fixed within the walls being connected in order to wooden unit that towel rack is installed.
Same as Fig. 2 a, shown in the b, the edge that also will pay the utmost attention to mounting disc 14 has a recess 16 at least, and base 4 has two flanges 17,18 at least, and flange 17,18 have at least one to have an eyelet 19 to insert screw 20, at least two flange 17,18 passes through to insert the screw 20 of eyelet 19 and recess 16 interlocks of at least one, thereby mounting disc 14 is fixed in the base 4.
Mounting disc 14 through screw by two or more holes 15 fixing on the wall after, will be contained in the mounting disc 14 by the base 4 of the described towel rack that assembles before. Flange 17,18 fastens the edge of mounting disc 14.Being connected by screw 20 of base 4 and mounting disc 14 is fixing, and screw 20 connects so that form friction between mounting disc 4 and base by the screw thread of the eyelet 19 of flange 18 and recess 16 interlocks of mounting disc 14.
