need mid-stand clamp for umbrella & speedlight

All the clamps that I've found for mounting a speedlight and umbrella on a light stand sit on top of the stand. I'm looking for one that will clamp onto the middle of the stand. Does anyone know of something like that?
Thanks

Manfrotto Super Clamp? Or use a boom to get it away from the stand.

Superclamp and umbrella bracket, or, for more flexibility a grip arm with the superclamp (http://www.bhphotovide​o.com …KIT_Grip_Kit_an​d_Bag.html) and the umbrella bracket.

You could also benefit from the Manfrotto 244 flexible arm (http://www.bhphotovide​o.com …able_Friction_M​agic.html), with or without camera bracket: https://www.youtube.co​m/watch?v=DB159XXbSIs

A Mf Superclamp - but - add the 6 in extension arm - it adds an upright spigot at the end, giving nice clearance from the mother stand.

For a really heavy light, use two, like this:

Grip arm for me.

So, researching all your suggestions, looks like what I need is called a grip head. Now, more research.
Thanks folks.

I'm not sure how much this will help you but it may give you an idea of how to do it.

I use an ancient mounting bracket from a Larson Reflectasol which was a high quality umbrella type reflector from many years ago. I use it for sports headshot to create a clamshell lighting scheme with a minimum of equipment to haul around.

Well, Bob, your shot #3 is exactly what I want to do. And the fact is, 30 or so years ago I had the same equipment! That's hilarious! Unfortunately, about 13 years ago I got the idea that I wasn't going to need them anymore (or the stands, or the Vivitar 283's, or the Quantum batteries... sigh) and sold them all. Oh well.

You ever heard of Finelight? The guy made all these amazing diffusers, reflectors, and stands, all from PVC. Bulky but they worked really well and cost pennies.
It's from the same era.

Here you go, $23.

Edit: Actually if you search for larson reflectasol at eBay there are quite a few options, some even less expensive.

The setup works pretty well. You do have to be aware of the light stand in front of you and keep it out of the frame.

Maybe. An Extension Grip Arm typically has a Grip head permanently fixed at one end. You'd probably want an extra spare Grip head to be able to grip the arm midway along its length. A Grip head on a stand is typically used at the stand's top - where the stand should have a full Baby pin top fitting - not just the more usual 5/8 X 35 mm spigot. All this can offer a rock solid solution but has costs, $ & Kg.

For a Speedlite plus shoot through umbrella, a Mf Superclamp-6 in Ext piece-spigot/stud-umbrella adapter, would be my choice. (There is a 50cm version of the extension instead of 6 in.)

Well so there are! Thanks Bob.

Here's my solution to OP's problem. I do have a certain Manfrotto umbrella adapter, but its popularity and metal build cannot disguise the awkward handling, uncertain hold, and faulty geometry. Standard grip gear is far sturdier and allows on-axis positioning:
